Abstract
PURPOSE This study aimed to develop and validate a nomogram for predicting the efficacy of transurethral surgery in benign prostatic hyperplasia (BPH) patients. METHODS Patients with BPH who underwent transurethral surgery in the West China Hospital and West China Shang Jin Hospital were enrolled. Patients were retrospectively involved as the training group and were prospectively recruited as the validation group for the nomogram. Logistic regression analysis was utilized to generate nomogram for predicting the efficacy of transurethral surgery. The discrimination of the nomogram was assessed using the area under the receiver operating characteristic curve (AUC) and calibration plots were applied to evaluate the calibration of the nomogram. RESULTS A total of 426 patients with BPH who underwent transurethral surgery were included in the study, and they were further divided into a training group (n = 245) and a validation group (n = 181). Age (OR 1.07, 95% CI 1.02-1.15, P < 0.01), the compliance of the bladder (OR 2.37, 95% CI 1.20-4.67, P < 0.01), the function of the detrusor (OR 5.92, 95% CI 2.10-16.6, P < 0.01), and the bladder outlet obstruction (OR 2.21, 95% CI 1.07-4.54, P < 0.01) were incorporated in the nomogram. The AUC of the nomogram was 0.825 in the training group, and 0.785 in the validation group, respectively. CONCLUSION The nomogram we developed included age, the compliance of the bladder, the function of the detrusor, and the severity of bladder outlet obstruction. The discrimination and calibration of the nomogram were confirmed by internal and external validation.

Abstract
To explore the clinical and pathological characteristics as well as therapies and prognosis of gray zone lymphoma (GZL). The clinical data of 10 GZL patients admitted to the First Affiliated Hospital of Soochow University from December 2016 to December 2022 were retrospectively collected. The clinical and pathological characteristics, therapies and prognosis were analyzed. The cut-off time for follow-up visits was December 31, 2022, and the median time for follow-up visits [M(Q1, Q3)] was 40.0 (28.3, 59.8) months. Treatment efficacy was divided into complete remission (CR), partial remission (PR), stable disease (SD) and progressive disease (PD). There were 6 males and 4 females, with a median age [M(Q1, Q3)] of 33.5 (27.3-39.5) years. Among them, 8 patients had mediastinal (thymus) involvement and 7 patients were accompanied with extranodal involvement. According to Ann Arbor staging, 1 case was in the limited stage and 9 cases were in the progressive stage. The immunophenotypes of 4 patients were strong expression of CD20, expression of CD30, and no expression of CD15. The immunophenotypes of 6 patients were unequal expression of CD20 and strong expression of CD30 and CD15. One patient received classical hodgkin lymphoma(cHL)-like immunochemotherapy and only achieved PR, and then received enhanced diffuse large b-cell lymphoma (DLBCL)-like immunochemotherapy to achieve CR. Five patients received enhanced DLBCL-like immunochemotherapy for induction therapy and achieved CR. All 4 patients who did not achieve CR achieved CR after receiving second-line or third-line salvage therapy. All patients were given autologous stem cell transplantation (ASCT) for consolidation therapy. One patient relapsed and died during the follow-up visit in the 33rd month, and the remaining patients currently maintained a state of sustained remission. It is found that GZL mostly occurs in young patients, mediastinal involvement is common, and diagnosis relies on pathological morphology and immunophenotype. GZL may be more sensitive to DLBCL-like intensive immune regimens. Sequential ASCT for consolidation can reduce the risk of relapse.

Abstract
Objective: To investigate the oncological outcomes of active surveillance (AS) in patients showing thyroid nodules measuring≤1 cm with highly suspicious ultrasound features. Methods: A prospective single-center cohort study. A total of 534 patients with highly suspicious thyroid nodules (2015 American Thyroid Association Nodule Sonographic Patterns and Risk of Malignancy: High Suspicion) were enrolled in this study, the patients received AS at Peking Union Medical College Hospital between January 2017 and November 2022 to assess oncological outcomes (disease progression, recurrence/metastasis rate, etc). The patients were followed up every 6 months for physical examination and neck ultrasound examination. And the value of tumor volume changes in evaluating tumor enlargement was explored too. Results: There were 413 females and 121 males in this cohort, with a mean age of (42.6±11.8) years. During a median follow-up period of 45.6 months (ranged from 3.5 to 176.0 months), disease progression occurred in 26 patients (4.9%) with highly suspicious thyroid nodules, characterized by a minimum 3-mm increase in tumor diameter in 19 patients (3.6%) and lymph node metastases in 7 patients (1.3%). Forty-seven (8.8%) patients opted for delayed surgery, with 29 patients due to a change in preference. There was no significant differences in pathologic and follow-up outcomes between patients with disease progression and preference change. Patients aged≤40 years had a higher cumulative incidence of 5-year disease progression than those aged>40 years (4.9% vs 1.9%, P=0.060). No patients experienced distant metastases or deaths. Among the 595 high-risk thyroid nodules with continuous volume assessment results and an increase in nodule diameter of less than 3 mm (including all high-risk nodules in patients with single or multiple nodules), 184 (30.9%) and 79 (13.3%) nodules exhibited volume increases of more than 50% and 100%, respectively, in multiple measurements. Among the nodules with volume changes exceeding 50% and 100%, the proportion of nodules with a baseline tumor diameter of≤0.5 cm was significantly higher than those with a diameter of>0.5 cm, at 69.0% vs 31.0% (P<0.001) and 77.2% vs 22.8% (P<0.001), respectively. Conclusions: Active surveillance in patients with highly suspicious subcentimeter thyroid nodules has good short-term oncological outcomes and can be considered a safe alternative to surgery. Due to the large variability in the measurement results of tumor volume, it is not suitable as an indicator for evaluating tumor enlargement.

Abstract
Objective: To investigate clinical effects of anterolateral thigh flap with blood supply source of medial femoral perforator in repairing the wounds on extremities. Methods: A retrospective observational study was conducted. From October 2018 to June 2021, Suzhou Ruihua Orthopedic Hospital admitted 12 patients (11 males and 1 female, aged 24-64 years) who met the inclusion criteria, and did not have the lateral circumflex femoral artery during anterolateral thigh flap resection, or changed to medial femoral perforator as a source of blood supply due to small perforator to repair the wound with flap transplantation. The wounds were on the upper limbs in 7 cases and on the lower limbs in 5 cases. The wound area after debridement was 8.0 cm×5.0 cm-24.0 cm×6.5 cm, and the applied flap area was 9 cm×6 cm-25 cm×7 cm. During transplantation, the perforating branch or source artery of the flap was anastomosed end to end with the vascular pedicle of the recipient area. Subcutaneous beauty suture was performed on all the donor wounds. After operation, the survival of the flap and vascular crisis were observed; and the wound healing at the donor site was observed. During follow-up, the texture of the flap and complications at the donor site were observed. At the last follow-up, the effect of flap repair was evaluated by using the modified self-made comprehensive efficacy rating table. Results: After operation, all the flaps of patients survived without vascular crisis; the wounds in the donor site healed smoothly. During follow-up of 6 to 26 months, the flaps had good texture; only linear scars remained in the donor area without scar contracture, pain or other discomfort. At the last follow-up, the total score of flap repair effect of 12 patients was 75-95, with an average of 87, of which 5 cases were rated as excellent, 6 cases as good, and 1 case as fair, and the proportion of excellent and good patients was 11/12. Conclusions: The application of anterolateral thigh flap with blood supply from the medial femoral perforator to repair wounds on extremities is an alternative method for the vascular variations such as no descending branch, oblique branch, or small perforator of the lateral circumflex femoral artery during the resection of the anterolateral thigh flap. This operation has the advantages of simple operation, small trauma, and others, which effectively ensures the smooth operation.

Abstract
Objective: To investigate the surgical methods and clinical effects of free superficial peroneal artery perforator flap in repairing small and medium-sized thermal crush injury wounds in the hand. Methods: A retrospective observational study was conducted. From August 2018 to December 2021, 12 patients (19 wounds) with small and medium-sized thermal crush injury in the hand who met the inclusion criteria were hospitalized in Suzhou Ruihua Orthopaedic Hospital, including 5 males and 7 females, aged from 30 to 54 years. The area of the wound was from 2.5 cm×2.0 cm to 14.0 cm×3.5 cm, and all the wounds were repaired by using free superficial peroneal artery perforator flaps from lower leg on one side (including single flap, multiple flaps, and multiple flaps with one pedicle resected from the same donor site). The area of the flap was from 3.5 cm×3.0 cm to 16.0 cm×4.0 cm. The wound in the donor site was sutured directly. The vascular crisis and survival of the flap were observed after operation. The texture, appearance, color, hyperpigmentation, sensation, and two-point discrimination of the flap repaired area were followed up, as well as the hyperplasia of scar and pain condition in the donor and recipient sites. At the last follow-up, the curative effect of flap repair was evaluated by the comprehensive evaluation scale, and the extension and flexion functions of the reserved digital joint were evaluated by the total active movement systematic evaluation method recommended by American Academy for Surgery of Hand. Results: One flap developed arterial crisis on the first day after operation but survived after timely exploration. The other 18 flaps survived successfully after operation. Follow-up of 4 to 24 months after operation showed good texture and appearance in the flap repaired area; the color of the flap repaired area was similar to that of the normal skin around the recipient site, without pigmentation; the protective sensation was restored in all cases, but there was no two-point discrimination; there was no obvious hypertrophic scarring or pain in the donor or recipient site. At the last follow-up, the curative effect of flap repair was evaluated with 3 flaps being excellent and 16 flaps being good; the extension and flexion functions of the reserved digital joint were also assessed, being excellent in 8 fingers, good in 9 fingers, and fair in 2 fingers. Conclusions: The blood supply of superficial peroneal artery perforator flap is sufficient and reliable, and multiple flaps of this type or multiple flaps with one pedicle can be resected from one donor site. The use of this flap to repair small and medium-sized thermal crush injury wounds in the hand results in minimal damage to the donor area, and good postoperative appearance and texture of the flap.

Abstract
Objective: To evaluate the efficacy and prognosis of orthopedic surgical resection surgery in patients with newly diagnosed multiple myeloma (NDMM). Methods: This retrospective cohort study collected clinical data of patients with NDMM who underwent surgery due to spinal cord compression or pathological long-bone fractures at the Peking Union Medical College Hospital from 1 January 2003 to 31 December 2021. Patients who received biopsy or vertebroplasty/kyphoplasty were excluded and patients with the same degree of bone disease and who did not undergo any surgical intervention were selected as controls. Visual analogue scale (VAS) and physical status (ECOG) scores, progression-free survival (PFS), and overall survival (OS) were compared. Statistical analysis included the χ2-test, t-test, and Kaplan-Meier methods. Results: Baseline data were compared between the surgical group (n=40 with 43 interventions) and the non-surgical group (n=80), and included sex, age, paraprotein type, International Staging System (ISS), number of lytic lesions, cytogenetic abnormalities, first-line treatment, and the proportion of patients receiving autologous stem cell transplantation (ASCT) (all P>0.05). Serum M protein levels in the surgical group were significantly lower than those of the non-surgical group [(21.95±16.44) g/L vs. (36.18±20.85) g/L, P=0.005]. The surgical lesions involved the axial skeleton (79.1%, 34/43) or the extremities (20.9%, 9/43). VAS and ECOG scores improved significantly after surgery (VAS: 2.30±0.80 vs. 6.60±1.50, P<0.001; ECOG: 2.09±0.59 vs. 3.09±0.73, P<0.001). The median follow-up time was 51 months. Kaplan-Meier survival analysis suggested that the median PFS (25 vs. 29 months) and OS (46 vs. 60 months) were comparable between the surgical and non-surgical intervention groups (both P>0.05). Subgroup analysis showed that among patients with ISS Ⅰ or those who had received ASCT, PFS in the surgical group was similar to that of the non-surgical intervention group (both P>0.05), while OS was worse (P=0.005, 0.017). Patients with ISS Ⅱ/Ⅲ scores or without ASCT had similar PFS and OS between the surgical and non-surgical intervention groups (all P>0.05). Cox multivariate analysis suggested that ISS and ASCT were independent prognostic factors for OS (ISS: HR=0.42, 95%CI 0.19-0.93, P=0.031; ASCT: HR=0.41, 95%CI 0.18-0.97, P=0.041), while orthopedic surgery did not influence survival (P=0.233). Conclusion: For patients with NDMM, orthopedic surgical resection decreased bone-related complications and improved quality of life, but did not affect survival.

Abstract
Objective: To investigate the curative effects of the superficial peroneal artery perforator flap carrying two and more homologous perforators in repairing hand and foot wounds. Methods: A retrospective observational study was conducted. From January to September 2021, 23 patients with hand and foot wounds combined with bone or tendon exposure who met the inclusion criteria were admitted to Suzhou Ruihua Orthopaedic Hospital, including 16 males and 7 females, aged 23 to 68 years. After expansion of the wound, the wound area was 3.0 cm×2.0 cm to 11.0 cm×4.0 cm. All the wounds were repaired with the superficial peroneal artery perforator flap carrying two and more homologous perforators. The area of the resected flap was 4.0 cm×2.0 cm to 12.0 cm×5.0 cm. All the wounds in donor areas were sutured directly. During the operation, the resection of the flap, the number and caliber of carried perforators, the caliber of superficial peroneal artery, the length of vascular pedicle, and the number of accompanying veins of the superficial peroneal artery were recorded. The survival of the flap, the occurrence of complications, and the wound healing in the donor area were observed after operation. The recovery of the donor and recipient areas was followed up. At the last follow-up, the comprehensive evaluation scale was used to evaluate the curative effect of flap repair, and the sensory grading scale was used to evaluate the sensory function of the recipient area. Results: Totally 24 flaps were successfully resected in surgical operations, carrying 56 superficial peroneal artery perforators in total, with the caliber of perforators of 0.20-0.70 mm. The calibers of all perforators carried by 7 flaps were smaller than 0.40 mm. Nineteen flaps carried 2 perforators each, 3 flaps carried 3 perforators each, 1 flap carried 4 perforators, and 1 flap carried 5 perforators. During the operation, the superficial peroneal artery was resected with a caliber of 0.40-1.50 mm, the vascular pedicle was 2-6 cm in length, and each superficial peroneal artery had two accompanying veins. After operation, all the flaps survived smoothly, no vascular crisis or distal necrosis occurred, and the wounds healed well in the donor area. During the follow-up of 6 to 10 months after operation, the color, texture, and elasticity of the recipient area were good. Among them, 6 recipient areas were thinned and reshaped because of bloating. There was only linear scar and no obvious scar hyperplasia or pigmentation in the donor area, without significant change in sensory or motor function. At the last follow-up, the curative effect evaluation of flap repair was excellent in 22 flaps and good in 2 flaps, and the sensory function evaluation of the recipient area was grade S3 in 1 area and grade S2 in 23 areas. Conclusions: The superficial peroneal artery perforator flap with two and more homologous perforators has sufficient and reliable blood supply and is effective in repairing hand and foot wounds. It provides an ideal solution for the clinical problem in which the original operation scheme is abandoned due to the existence of only multiple slender perforators of caliber smaller than 0.40 mm, and only a single perforator in the operative field that cannot satisfy the needs of the flap blood supply and recipient area.

Abstract
BACKGROUND Survival is a key metric of the effectiveness of a health system in managing cancer. We set out to provide a comprehensive examination of worldwide variation and trends in survival from brain tumors in adults, by histology. METHODS We analyzed individual data for adults (15-99 years) diagnosed with a brain tumor (ICD-O-3 topography code C71) during 2000-2014, regardless of tumor behavior. Data underwent a 3-phase quality control as part of CONCORD-3. We estimated net survival for 11 histology groups, using the unbiased nonparametric Pohar Perme estimator. RESULTS The study included 556,237 adults. In 2010-2014, the global range in age-standardized 5-year net survival for the most common sub-types was broad: in the range 20%-38% for diffuse and anaplastic astrocytoma, from 4% to 17% for glioblastoma, and between 32% and 69% for oligodendroglioma. For patients with glioblastoma, the largest gains in survival occurred between 2000-2004 and 2005-2009. These improvements were more noticeable among adults diagnosed aged 40-70 years than among younger adults. CONCLUSIONS To the best of our knowledge, this study provides the largest account to date of global trends in population-based survival for brain tumors by histology in adults. We have highlighted remarkable gains in 5-year survival from glioblastoma since 2005, providing large-scale empirical evidence on the uptake of chemoradiation at population level. Worldwide, survival improvements have been extensive, but some countries still lag behind. Our findings may help clinicians involved in national and international tumor pathway boards to promote initiatives aimed at more extensive implementation of clinical guidelines.

Abstract
Objective: To explore the anatomical characteristics of the anterolateral thigh perforator flap pedicled with oblique branch trunk of lateral circumflex femoral artery in the muscular septum and the clinical effect of this flap in repairing skin and soft tissue defects in the extremities. Methods: A retrospective observational study was conducted. From December 2020 to April 2021, 59 patients with skin and soft tissue defects in the extremities admitted to the Department of Hand Surgery of Suzhou Ruihua Orthopaedic Hospital met the inclusion criteria, including 46 males and 13 females, aged 20 to 81 years. The wound area after debridement ranged from 8 cm×5 cm to 38 cm×20 cm. According to the condition of the wound, the perforators in the anterolateral femoral region on the unaffected side were located by color Doppler ultrasound. The anterolateral thigh perforator flap with the oblique branch of lateral circumflex femoral artery as the source artery was designed, and the wound was repaired by unilateral flap or series combination of bilateral flaps (with the area of unilateral flap ranging from 7 cm×5 cm to 37 cm×11 cm). The wound of the donor site was sutured directly. The following items were recorded, including the number of perforators in the anterolateral femoral region marked before operation, the course characteristics of oblique branch trunk of lateral circumflex femoral artery and its perforators, and the number, origin, and type of perforators observed during operation, the flap repair mode and the flap harvest time. After operation, the survival condition of the flap, the wound healing time in the recipient site, and the suture healing in the donor area were observed, and the recovery of the donor and recipient areas was followed up. At the last follow-up, the sensation function evaluated by sensory rating scale of British Medical Research Association and two-point discrimination of the area transplanted with flap were recorded, and the improved comprehensive curative effect evaluation scale of flap was used to evaluate the repair effect of the flap. Results: A total of 156 perforators were marked in the anterolateral femoral region before operation, and 144 perforators were observed during the operation, of which 98 came from the oblique branch of the lateral circumflex femoral artery, and the first perforator of the oblique branch was the intermuscular septal perforator. Once formed, most oblique branch trunk of lateral circumflex femoral artery in the muscular septum could be divided into the deep branch and the superficial branch at the middle and upper 1/3 junction of the line between the anterior superior iliac spine and the lateral edge of the patella, the deep branch mainly ran in the muscle of vastus intermedius and vastus lateralis, and rarely developed the skin perforators, while the superficial branch mainly ran in the muscular septum between the rectus femoris and the vastus lateralis, and grew out the perforators to the proximal skin of the anterolateral femoral region. Fifty-six patients were repaired with unilateral flap and 3 patients with bilateral flap in series combination, with the harvesting time of the unilateral flap ranged from 9 to 99 min. Three patients developed arterial crisis within 48 hours after operation and survived after timely exploration; the flap of 1 patient developed necrosis 11 days after operation and was repaired by abdominal split-thickness skin graft; the other flaps survived smoothly. The wound healing time in the recipient area was 10 to 42 days after operation, and the sutures in the donor area healed well. During the follow-up of 6 to 10 months, 8 patients underwent thinning and plastic surgery 6 months after operation because of bloating in the flap transplantation area, while the other patients had a good shape of the flap transplantation area, with no deep tissue infection such as osteomyelitis, with soft texture, good elasticity, no pain, and good blood circulation; all the donor areas were left with linear scars, normal blood circulation in the distal extremities, no limitation of knee joint motion or quadriceps muscle strength. At the last follow-up, the sensation function was restored in the flap transplantation area of the affected limb, including 14 cases of S1 grade and 45 cases of S2 grade; there was only one point of two-point discrimination; the curative effect evaluation of flap repair included excellent in 24 cases, good in 35 cases, and general in 3 cases. Conclusions: The anterolateral thigh perforator flap pedicled with oblique branch trunk of lateral circumflex femoral artery in the muscular septum has the advantages of relatively concealed donor area, large cutting width, and simple operation during surgery. It protects the donor area to the greatest extent while repairing skin and soft tissue defects in the extremities, and is a useful supplement to the classic anterolateral thigh perforator flap.

Abstract
Objective: To explore the clinical effects of free superficial peroneal artery perforator flaps in repairing skin and soft tissue defects of the hallux. Methods: A retrospective observational study was conducted. From January 2020 to January 2021, 13 patients with skin and soft tissue defects of the hallux who met the inclusion criteria were admitted to Department of Foot and Ankle Surgery of Ruihua Affiliated Hospital of Soochow University, including 12 males and 1 female, aged 26 to 53 years. Before operation, the perforating point of the superficial peroneal artery perforator was located by color Doppler ultrasound on the calf on the same side of the affected hallux and marked on the body surface. The operation was performed under spinal anesthesia combined with continuous epidural anesthesia. The area of skin and soft tissue defect after debridement was 4.5 cm×2.5 cm to 12.0 cm×3.0 cm. According to the size and shape of the wound, the superficial peroneal artery perforator flap was designed with the line between the fibular head and the lateral malleolus tip parallel shifting 2 cm to the tibial side as the flap axis line, and the perforating point of the perforator near the midpoint of the axis line as the center. The cut area of the flap was 5.0 cm×3.0 cm to 13.0 cm×4.0 cm, and part of the deep fascia was cut when the pedicle was freed. The donor site wound was sutured directly. During the operation, the number and type of the perforator and the cutting time of the flap were recorded, and the length of the perforator pedicle and diameter of the perforator were measured. The survival of the flap, the healing time and the healing condition of the donor and recipient areas were recorded after operation. The color, texture, elasticity of the flap, standing and walking functions of patients, the recovery of the donor area, and the patients' satisfaction with the recovery of the donor and recipient areas were recorded during the follow-up. At the last follow-up, the sensation of the flap was evaluated by the British Medical Association sensory function evaluation standard, the function of the affected limb was evaluated by the American Society of Foot and Ankle Surgery scoring system, and the excellent and good rate of the function of the affected limb was calculated. Results: A total of 13 perforators of the superficial peroneal artery were detected during the operation, all of which were septocutaneous perforators, and the perforator diameter was 0.3 to 0.5 mm. The vascular pedicle length was 2 to 5 cm. Flap cutting time was 11 to 26 minutes. The flaps of 13 patients all survived completely. The wounds at the donor and recipient sites healed well 9 to 18 days after operation. During follow-up of 6 to 14 months, the flaps had good color, texture, and elasticity; 11 patients had no obvious bloated appearance, and the other 2 patients underwent flap thinning and plastic surgery in the second stage because of their bloated appearance; all the patients returned to normal walking and standing functions. There was only one linear scar left in the donor site, with no obvious scar hyperplasia or hyperpigmentation. All the patients were satisfied with the recovery of the donor and recipient areas. At the last follow-up, the sensation of the flap was evaluated as grade S3 in 2 cases, grade S2 in 9 cases, and grade S1 in 2 cases; the function of the affected limb was evaluated as excellent in 7 cases and good in 6 cases, with an excellent and good rate of 100%. Conclusions: The free superficial peroneal artery perforator flap has relatively constant vascular anatomy, which is thin and wear-resistant, with less damage to the donor site after flap excision, and can preserve the shape and function of the hallux to the greatest extent. It is an effective method for repairing skin and soft tissue defect of the hallux.

Abstract
Objective: To estimate stomach cancer incidence and mortality in Henan, 2016 and analyze the trend of stomach cancer incidence and mortality from 2010 to 2016. Methods: Stomach cancer related data in 2016 was extracted from Henan cancer registration and follow-up system. All data were qualified in validity, reliability and completeness according to the Guideline on Cancer Registration in China and International Agency for Research on Cancer (IARC/IACR). The incidence and mortality of stomach cancer were estimated by areas, gender and age based on the quality data and the registered population data of Henan province in 2016. The epidemic trend of stomach cancer was also been evaluated based on the age-standardized incidence and mortality by Chinese population (ASR China) from 2010 to 2016. Results: In 2016, the estimated incident cases of stomach cancer were 44 311. The incidence was 41.07/100 000, ASR China was 30.17/100 000, ASR by world population (ASR world) was 30.36/100 000, and the cumulative incidence rate was 3.84%. The incidences of male and female were 55.65/100 000 and 25.35/100 000, respectively. Meanwhile, 32 927 people died of stomach cancer in Henan. The mortality was 30.52/100 000, ASR China was 21.45/100 000, ASR world was 21.54/100 000, and the cumulative mortality was 2.53%. From 2010 to 2016, both the ASR China for incidence and mortality of stomach cancer in Henan showed a steady downward trend. In rural, the ASR China for incidence and mortality decreased rapidly, while the stable trend was observed in urban. Nevertheless, the incidence and mortality of stomach cancer in rural were still higher than those in urban. Conclusions: The incidence and mortality of stomach cancer in Henan province showed steadily declining trend from 2010 to 2016, and the geographical distribution difference between rural and urban areas was gradually narrowing. However, the disease burden was still high in 2016.

Abstract
Objective: To estimate the incidence and mortality of esophageal cancer in 2016 and their changing trend during 2010-2016 according to the cancer registration data in Henan province. Methods: The data quality including completeness, validity, and reliability of local registries which submitted the cancer registration data of 2016 were assessed according to the criteria of Guideline on Cancer Registration in China and IARC/IACR. Esophageal cancer cases (ICD10: C15) were extracted from the database, and the incidence and mortality stratified by gender, age, and areas (urban/rural) were calculated, the incidence and mortality of provincial cancer were estimated combined with provincial population data. China's 2000 census population and Segi's population were used to calculate the age-standardized rate. Joinpoint model was used to estimate the changing trend of age standardized incidence and mortality along with the calendar year. Results: Approximately 40.10 thousand new esophageal cancer cases were diagnosed in Henan in 2016, accounting for 13.46% of all new cancer cases, and it ranked the third among cancer of all sites. The crude incidence of esophageal cancer was 37.21/100 000 with an age-standardized incidence rate by China standard population (ASIRC) of 26.74/100 000 and an age-standardized incidence rate by world standard population (ASIRW) of 27.12/100 000. The incidence of esophageal cancer in males was higher than that in females, with the ASIRC of 34.53/100 000 and 19.19/100 000, respectively. It was higher in rural areas than that in urban areas, with the ASIRC of 28.13/100 000 and 20.90/100 000, respectively. About 29.30 thousand deaths of esophageal cancer in Henan in 2016, accounting for 15.61% of all cancer deaths in Henan, which ranked the third among cancer of all sites. The crude mortality rate was 27.14/100 000 with an age-standardized mortality rate by China standard population (ASMRC) of 18.74/100 000 and an age-standardized mortality rate by world standard population (ASMRW) of 18.78/100 000. The mortality in males was higher than that in females, with the ASMRC of 24.78/100 000 and 13.12/100 000, respectively. It was also higher in rural areas than that in urban areas, with the ASMRC of 19.48/100 000 and 15.73/100 000, respectively. The ASIRC and ASMRC were declining with annual percent change (APC) of 3.12% (APC=-3.12%; 95%CI: -5.30%, -0.90%; P=0.015) and 2.47% (APC=-2.47%; 95%CI: -4.70%, -0.20%; P=0.039) during 2010-2016. However, the significant declining trend was only observed in rural areas in Henan, and the changing trend was same between males and females. Conclusions: The incidence and mortality of esophageal cancer are declining since 2010, however, the disease burden remains large in Henan. Therefore, comprehensive prevention and control efforts should be strengthened according to its epidemic characteristics and risk factors.

Abstract
Objective: To explore the clinical effects of anterolateral thigh perforator flap with sensory nerves in repairing the plantar skin and soft tissue defects. Methods: From January 2016 to March 2019, 13 male patients with plantar skin and soft tissue defects were admitted to the Department of Foot and Ankle Surgery of Ruihua Affiliated Hospital of Soochow University, aged 27 to 73 years. The retrospective cohort study was conducted. The wounds of 4 patients underwent 2 times of debridement. The wounds of 9 patients underwent 1 time of debridement and 1 or 2 time(s) of vacuum sealing drainage. Then all the wounds of patients were repaired with flaps when the wounds were clean and dry with no purulent exudation and were negative in secretion culture. The wound areas of this group of patients after wound debridement were 13.0 cm×5.5 cm to 36.0 cm×10.5 cm, and the wounds were repaired with anterolateral thigh perforator flaps with sensory nerves with area of 14 cm×6 cm to 37 cm×11 cm. The wound of 1 patient was repaired with a bilobed flap. The oblique or descending branch of the lateral circumflex femoral artery and its accompanying vein in the flap were anastomosed with the posterior tibial artery and its accompanying vein or the medial plantar artery and its accompanying vein in recipient sites. The lateral femoral cutaneous nerve in the flap was anastomosed with the recipient saphenous nerve or medial plantar cutaneous nerve. The donor sites were directly sutured. The survival of flaps and the healing of wounds in the donor and recipient areas were recorded, and the ulcers of the plantar repaired flap were followed up for 3 months after operation. The sensory function of the flap was evaluated by the sensory evaluation standard of British Medical Research Council (BMRC), and the ankle and foot function score system of American Orthopedic Foot and Ankle Society (AOFAS) was used for comprehensive functional evaluation at the last follow-up. Results: All the 14 flaps in 13 cases survived, and venous crisis occurred in two cases and the flaps survived smoothly after the venous re-anastomosis. One patient developed deep tissue infection after being discharged and was healed after secondary debridement. The donor and recipient areas of the remaining patients healed well. The patients were followed up for 6 to 18 months, the shape of flaps was slightly bloated in 5 patients, and the shape and texture of flaps in the other 8 patients were good. Six patients had ulcers in flaps at 3 months of follow-up after operation, which were healed after stopping weight-bearing activities. At the last follow-up, little linear scar hyperplasia could be seen in the donor site of patients; the BMRC sensory function evaluation results were S1 grade in 4 cases, S2 grade in 7 cases, and S3 grade in 2 cases; the AOFAS scores were excellent in 3 cases, good in 7 cases, fair in 2 cases, and poor in 1 case. Conclusions: The anterolateral thigh perforator flaps with sensory nerves can repair the plantar skin and soft tissue defects with the donor sites directly sutured and good shape of flaps, which provide a good treatment method for the recovery of plantar proprioceptive sensation and weight-bearing function.

Abstract
Objective: To explore the clinical effects of bilateral overlength anterolateral femoral perforator flaps connected in series or parallel in repairing large area of wounds in limbs. Methods: From January 2017 to July 2019, 9 patients with large area of skin and soft tissue defects in limbs were admitted to the Departments of Hand Surgery and Foot and Ankle Surgery of Ruihua Affiliated Hospital of Soochow University, including 8 males and 1 female, aged 36 to 63 years. The retrospective cohort study was conducted. The wound areas of patients after debridement were 20 cm×15 cm to 30 cm×25 cm, and the wounds were repaired with bilateral overlength anterolateral femoral perforator flaps. One main artery defect in the receiving area of 4 patients was repaired with bilateral flaps connected in series. Two main artery defects in the receiving area of 5 patients were repaired with bilateral flaps connected in parallel. A total of 18 flaps were excised, and the area of a single flap ranged from 20 cm×8 cm to 46 cm×9 cm. The donor sites of 17 flaps were sutured directly, and the donor site of 1 flap was repaired with free full-thickness skin graft from hypogastrium. Harvesting time of flaps, survival condition of flaps after surgery, and wound healing time, and flap observation, two-point discrimination distance of flaps, functional recovery of joint and appearance of recipient site, and recovery of donor site during follow-up were recorded. Results: In this group of 9 patients, the flap harvesting time was 1.0 to 4.5 hours, and all the 18 flaps survived. The wound healing time of recipient site was 18 to 72 days after flap transplantation. They were followed up for 6 to 34 months. The shape of the recipient site was satisfactory, with no deep tissue infection such as osteomyelitis. Four flaps in 2 patients were bloated and were thinned in 6 months after operation; 4 flaps in 2 patients had skin pigmentation on the edge of the flap; the flap of one patient was scalded but healed by dressing change, with patchy scar being observed during follow-up. The rest of the flaps were soft, elastic, and painless with good blood supply. All the flaps restored with protective sensation, with only one point in two-point discrimination. Only linear scars remained in the donor sites of 17 flaps. All the limbs had good blood supply in the distal end of donor sites, and no restriction occurred in range of motion of knee joint and quadriceps muscle strength. Conclusions: The bilateral overlength anterolateral femoral perforator flaps connected in series or parallel have constant anatomy, reliable blood supply, and flexible combination. It is an ideal surgical method for repairing large area of skin and soft tissue defects in limbs at one time.

Abstract
Objective: To evaluate the compliance rate and its impact factors of liver cancer screening for high-risk groups in urban areas of Henan Province from 2013 to 2019. Methods: Residents of 40-74 years old in 8 cities of Henan province were selected to investigate the risk factors and liver cancer risk assessment. Subjects with high risk of liver cancer received AFP combined ultrasonography for screening. Chi-square tests were used to compare the differences in liver cancer screening participation rates between groups. Multivariate logistic regression models were applied to explore the potential factors correlating to the compliance of liver cancer screening. Results: Overall, 3 6781 participants who met the inclusion criteria were included in this analysis, and 17 241 of them took the following liver cancer screening, yielding a participation rate of 46.87%. The participation rate varied greatly across cities, ranging from 62.50% to 38.59%. Moreover, the participation rate varied greatly across periods, ranging from 52.77% in 2014-2015 to 38.14% in 2013-2014. The multivariate Logistic regression analyses showed that: female, older, high education degree, cigarette and alcohol intake, infrequent physical exercise, chronic hepatitis B, chronic hepatitis C, fatty liver, gallstones and a family history of liver cancer were inclined to accept liver cancer screening (P<0.05). Conclusions: The overall participation rate of liver cancer screening among high-risk population is less than 50% in urban areas of Henan Province. Implement of effective interventions targeting the specific high-risk populations might improve the overall compliance rate of liver cancer screening in the future.

Abstract
Objective: To analyze the effects of esophageal cancer screening in Henan rural areas with cancer screening program from 2014 to 2018. Methods: From July 2014 to June 2019, according to the National Early Diagnosis and Treatment of Upper Gastrointestinal Cancer in Rural Areas Project, cluster sampling method was adopted in 16 counties/county-level cities in rural areas with high incidence of esophageal cancer in Henan province. Endoscopic iodine staining and indicative biopsy were used to screen esophageal cancer. The patients with mild and moderate dysplasia confirmed in screening were followed up. The distribution of esophageal diseases in the screening population was calculated, and Chi-square test was used to compare the differences of detection rate and early diagnosis rate between the primary screening population and the follow-up population. Results: The age of 116 630 primary screening population was (54.29±7.70) years old, and the proportion of males was 41.2% (48 108). In the primary screening population, patients with normal esophagus, mild to moderate dysplasia, severe dysplasia and above accounted for 92.91% (108 363), 6.03% (7 035) and 1.06% (1 232), respectively. The detection rate of esophageal cancer was 1.06% (1 232/116 630), and the rate of early diagnosis was 85.80% (1 057). Among the follow-up population of 6 154 people, those with normal esophagus, mild to moderate dysplasia, severe dysplasia and above diseases accounted for 63.45% (3 905), 33.13% (1 519) and 3.41% (210), respectively. The detection rate of esophageal cancer was 3.41% (210/6 154), and the rate of early diagnosis was 91.90% (1 939). Compared with the primary screening population, the risk of esophageal cancer was higher in the overall follow-up population, people either with mild or with moderate dysplasia diagnosed in primary screening, with OR values (95%CI) of 3.23 (2.78, 3.75), 1.85 (1.49, 2.29) and 8.13 (6.69, 9.88), respectively. Conclusion: From 2014 to 2018, in the early diagnosis and early treatment of upper digestive tract cancer project in rural areas of Henan Province, the detection rate of the follow-up population is significantly higher than that of the primary screening population. Improving follow-up rate and paying more attention to the screening of people who need follow-up could further improve the screening effect.

Abstract
Objective: To estimate cancer incidence and mortality of kidney and unspecified urinary organs in China using cancer registry data in 2015. Methods: The cancer registry data from 501 local cancer registries in China were collected, checked and assessed based on the criteria of data quality control of the National Central Cancer Registry of China (NCCRC), and data from 368 registries were qualified for the analysis. Cancer incidence and mortality rates of kidney and unspecified urinary organs stratified by geographical location (eastern, middle, western areas), gender, age groups were calculated. Population data of 2015 was used to estimate the cancer cases and deaths of kidney and unspecified urinary organs in China. Chinese standard population in 2000 and Segi's world population were used for the calculation of age-standardized incidence and mortality rates. Results: A total of 74.2 thousand new cancer cases of kidney and unspecified urinary organs were diagnosed in 2015, 46.9 thousand of them were male, while 27.3 thousand were female, with a crude incidence rate of 5.40/10(5). The age-standardized incidence rates by Chinese (ASIRC) and world standard population (ASIRW) were 3.57/10(5) and 3.56/10(5), respectively. A total of 53.4 thousand and 20.8 thousand new cases were diagnosed in urban and rural area, with incidence rates of 6.93/10(5) and 3.45/10(5), respectively. The ASIRC of urban area was higher than that of rural area. There were 39.2 thousand, 20.6 thousand, and 14.4 thousand new cases diagnosed in eastern, middle, and western areas of China, respectively. The crude incidence rates were 7.60/10(5), 4.47/10(5), and 3.63/10(5), respectively, with a descend ASIRC of each area. A total of 27.1 thousand death cases reported, of them 16.9 thousand were male, while 10.2 thousand were female, with a crude mortality rate of 1.97/10(5), both of the ASIRC and ASMRW were 1.21/10(5). The deaths of urban and rural area were 19.5 thousand and 7.6 thousand cases, with the crude mortality rates of 2.53/10(5) and 1.26/10(5), respectively. The ASIRC of urban area was higher than that of rural area. There were 13.4 thousand, 8.4 thousand, and 5.1 thousand death cases reported in eastern, middle, and western areas, respectively, the crude mortality rates were 2.61/10(5), 1.83/10(5) and 1.30/10(5), respectively, with a descend ASIRC of each area. Conclusion: The disease burden of kidney cancer differs between urban area and rural area, and differs among eastern, middle, and western areas of China, therefore, different prevent and treatment strategies should be taken in different areas of China.

Abstract
Objective: To study the significance of induction chemotherapy and subsequent comprehensive therapy for overall survival rate (OS) and larynx dysfunction-free survival rate (LDFS) in patients with advanced hypopharyngeal carcinoma. Methods: Patients who met the inclusion criteria with the diagnoses of advanced hypopharyngeal carcinoma between 2011 and 2017 received 2 or 3 cycles of TPF regimen induction chemotherapy. Patients who attained complete response (CR) received radical chemotherapy. Patients who attained partial response (PR) and the reduction of tumor volume was more than 70% were defined as large PR and received concurrent chemoradiotherapy. When the tumor volume reduction of PR patients was less than 70%, they were defined as small PR. (CR+large PR) group was defined as effective group. Patients who did not reach CR and large PR were defined as uneffective group and underwent radical surgery and received adjuvant radiotherapy as appropriate after the surgery. The end points of the study were OS, progression-free survival (PFS) and LDFS. Chi-square (χ(2)) test was used for correlation analysis. Survival analysis was performed by the Kaplan-Meier method with a Log-rank test. Cox proportional hazards model was used for univariate and multivariate survival analysis. Results: A total of 260 patients were enrolled in the study. The follow-up period ranged from 5 to 83 months, with an average of 24.7 months. The 3-year and 5-year OS rate was 46.0% and 32.6%, respectively. The 3-year and 5-year PFS rate was 41.0% and 26.6%, respectively. The 3-year and 5-year LDFS rate was 37.9% and 24.8%, respectively. Poor outcome of induction chemotherapy, advanced N stage, strong positive Ki-67 immunohistochemistry (all P<0.001) were negative prognostic factors. The advanced clinical stage was positively related to the poor outcome of induction chemotherapy (P=0.015). There was no significant difference in OS and PFS between the large PR group and the small PR group (all P>0.005). Conclusion: TPF regimen induction chemotherapy and subsequent comprehensive therapy for patients with advanced hypopharyngeal carcinoma may improve the quality of life of patients, with high OS rate and LDFS rate.

Abstract
AIMS This study evaluated the effects of Bacillus amyloliquefaciens TL106, isolated from Tibetan pigs' faeces, on the growth performance, immune response, intestinal barrier function, morphology of jejunum, caecum and colon, and gut microbiota in the mice with enterohaemorrhagic Escherichia coli (EHEC)-induced intestinal diseases. METHODS AND RESULTS In all, 40 female C57BL/6J mice were randomly divided into four groups: mice fed a normal diet (Control), mice oral administration of TL106 daily (Ba), mice challenged with EHEC O157:H7 on day 15 (O157) and mice oral administration of TL106 daily and challenged with EHEC O157:H7 on day 15 (Ba+O157). The TL106 was administrated to mice for 14 days, and mice were infected with O157:H7 at day 15. We found that TL106 could prevent the weight loss caused by O157:H7 infection and alleviated the associated increase in pro-inflammatory factors (TNF-α, IL-1β, IL-6 and IL-8) and decrease in anti-inflammatory factor (IL-10) in serum and intestinal tissues of mice caused by O157:H7 infection (P < 0·05). Additionally, TL106 could prevent disruption of gut morphology caused by O157:H7 infection, and alleviate the associated decrease in expression of tight junction proteins (ZO-1, occludin and claudin-1) in jejunum and colon (P < 0·05). In caecum and colon, the alpha diversity for bacterial community analysis of Chao and ACE index in Ba+O157 group were higher than O157 group. The TL106 stabilized gut microbiota disturbed by O157:H7, including increasing Lachnospiraceae, Prevotellaceae, Muribaculaceae and Akkermansiaceae, and reducing Lactobacillaceae. CONCLUSIONS We indicated the B. amyloliquefaciens TL106 can effectively protect mice against EHEC O157:H7 infection by relieving inflammation, improving intestinal barrier function, mitigating permeability disruption and stabilizing the gut microbiota. SIGNIFICANCE AND IMPACT OF THE STUDY Bacillus amyloliquefaciens TL106 can prevent and treat intestinal disease induced by EHEC O157:H7 in mice, which may be a promising probiotic for disease prevention in animals.

Abstract
1. Probiotic fermented feed (PFF) has been widely used in poultry production. The current study was designed to investigate whether PPF could alleviate the negative effects of hypoxia on yellow-feathered broilers reared at high altitude on the Tibet Plateau. 2. A total of 480, one-day-old male Lingnan yellow-feathered broilers were divided into four treatment groups with six replicates, each containing 20 broiler chickens. Broilers in the four groups were offered either a basal diet (without antibiotics) or test diets containing 5, 10 and 15% of PFF respectively. The experiment lasted for eight weeks. 3. Birds fed the 10% PFF diet exhibited increased (P < 0.05) average daily gain (ADG) on d 28 and 56, body weight (BW) on d 56, total tract apparent digestibility (TTAD) of dry matter (DM), crude protein (CP) and gross energy (GE). Feeding diets supplemented with 10% PFF increased (P < 0.05) digestive activity and gut development in duodenum and jejunum. Supplementation with 10% or 15% PFF significantly increased (P < 0.05) the caecal populations of Lactobacilli and Bifidobacteria spp. and decreased (P < 0.05) caecal E. coli and Salmonella spp. on d 28 and 56. 4. The ADG and BW on d 56, protease activity in duodenum on d 56 and jejunum on d 28 and 56, villus height and villi absorptive area in duodenum and jejunum and caecal Bifidobacteria spp. showed a quadratic (P < 0.05) dose response as supplemental PFF level increased. The TTAD of DM and CP and caecal Lactobacilli spp. increased linearly with PFF level. The caecal populations of E. coli and Salmonella spp. decreased linearly with PFF level. 5. In conclusion, addition of PFF in broiler diets had the potential to improve production performance, nutrient utilisation, intestinal digestive function and caecal microflora in yellow broiler chickens raised at high altitude.

Abstract
Objective: To evaluate the compliance of low-dose computed tomography (LDCT) screening for high-risk groups of lung cancer and influencing factors in urban area of Henan province during 2013-2017. Methods: Cluster sampling method was used to select the residents of 40-74 years old in Henan for cancer risk factor investigation and lung cancer risk assessment. Subjects with high risk of lung cancer received LDCT screening. The differences of LDCT receiving rates between groups were compared with χ(2) tests, and the time trend of rates were tested with the Cochran- Armitage trend test. The potential factors correlating to the compliance of LDCT screening were identified with multivariate logistic regression models. Results: Overall, 35 672 participants who met the inclusion criteria were included in this analysis, and 13 383 of them received LDCT screening, the receiving rate was 37.52%. The receiving rate varied greatly across cities, ranging from 38.47% to 26.73% (P<0.05). Moreover, the receiving rate varied greatly across periods, ranging from 29.22% during 2013-2014 to 43.30% during 2014-2015, and the receiving rate increases gradually as the screening year increases (P<0.001). The multivariate logistic regression analyses showed that: being female, age 45-69 years, with education level of junior high school/high school, previous smoking, drinking or previous drinking, infrequent physical exercise, history of tuberculosis, history of chronic bronchitis, history of emphysema, history of asthma bronchiectasis and family history of lung cancer were positive factors for receiving LDCT screening (All P<0.05). Conclusions: The overall compliance of LDCT screening in high-risk population of lung cancer was still not high in urban area of Henan. Implementation of effective interventions targeting the specific high-risk populations might improve the overall compliance of LDCT screening in the future.

Abstract
Objective: To study the compliance of endoscopic screening for high-risk population of upper gastrointestinal cancer and relevant factors in urban areas of Henan Province, 2013-2017. Methods: The study participants were from the Cancer Screening Program in Urban Henan Province, China. From October 2013 to October 2017, 43 423 residents, who were evaluated as high-risk population for upper gastrointestinal cancer, were recruited from Zhengzhou, Zhumadian and Anyang. The cancer risk assessment questionnaire was used to collect basic demographic characteristics, dietary habits, living environment and habits, psychology and emotions, disease history and family history of cancer, and women's physiological and reproductive history. The data of endoscopic screening was obtained from hospitals participating in the Cancer Screening Program. Multivariate logistic regression model was applied to explore potential factors related to the compliance of endoscopic screening. Results: The age of study participants was(55.49±8.15) years old, and 44.00% (19 105) were male. About 18.41% of study subjects (7 996) took the endoscopic screening. The multivariate logistic regression analysis showed that females, individuals aged 45-64 years old, with junior high school education or above, unmarried/divorced/widowed, previous smoking, alcohol drinking, infrequent physical exercise, history of reflux esophagitis, history of superficial gastritis, history of gastric ulcer, history of duodenal ulcer, history of gastric polyps and family history of upper gastrointestinal cancer were more likely to accept endoscopic screening. Conclusion: The overall participation rate of endoscopic screening among high-risk population of upper gastrointestinal cancer was still low in urban areas of Henan Province. Gender, age, education, marital status, smoking, alcohol consumption, physical activity, history of upper gastrointestinal disease and family history of upper gastroin testinal cancer were associated with the compliance of endoscopic screening.

Abstract
BACKGROUND Persistent or recurrent haemospermia often occurs in individuals with ejaculatory duct obstruction (EDO). This study aimed to evaluate the efficacy and safety of transurethral resection of the ejaculatory duct (TURED) combined with seminal vesiculoscopy in treating persistent or recurrent haemospermia in men with EDO. METHODS From June 2014 to March 2018, 103 consecutive patients with EDO who underwent TURED combined with seminal vesiculoscopy for persistent or recurrent haemospermia at the Department of Urology of West China Hospital were enrolled into this retrospective study. The patients were evaluated mainly by detailed history-taking and performing semen analysis, transrectal ultrasonography, and magnetic resonance imaging. RESULTS Among the 103 patients, 79 (76.70%) had cysts of the lower male genitourinary tract; 63 (61.17%) had blood clots; and 32 (31.07%) had calculi in the seminal vesicle and/or prostatic utricle. The duration of postoperative follow-up was 12 months, and the symptoms of haemospermia disappeared in 96 (93.20%) patients. There was no significant difference in the semen PH and sperm count before and after surgery; however, the ejaculate volume and sperm motility significantly improved postoperatively. Except for two cases of acute urinary retention and one case of watery ejaculate after surgery, no severe postoperative complications, including epididymitis, urethral stricture, urinary incontinence, retrograde ejaculation, or rectal injury, were observed. CONCLUSION TURED combined with seminal vesiculoscopy is a suitable method for the diagnosis and treatment of persistent or recurrent haemospermia in men with EDO.

Abstract
Objective: To evaluate the postoperatively hidden blood loss of elderly intertrochanteric fracture patients fixed with combined external fixator, and to explore the correlation between hidden blood loss and age. Methods: A retrospective analysis was conducted on 60 elderly intertrochanteric fracture patients who were admitted to the Department of Orthopedics of Hebei Provincial Hospital from January 2016 to May 2019. All the fractures were fixed with combined external fixators. The patients were divided into two groups according to the age: there were 31 cases in group A (60-80 years old) and 29 cases in group B (≥80 years old). The Gross equation and the Nandler formula were used to evaluate the amount of hidden blood loss based on changes in hematocrit (Hct) at the day preoperatively, 3 days postoperatively and the weight. The data were compared between the two groups by independent-sample t test. Results: The decreased Hct, hemoglobin(Hb) and the dominant blood loss and hidden blood loss in group A and B was 3.4%±1.7%, (13±7) g/L, (25±6) ml, (186±7) ml and 3.8%±1.2%, (13±3) g/L, (24±8) ml, (194±7) ml, respectively. There was no significant differences in the dominant and hidden blood loss between the groups (t=0.309, 0.883, both P>0.05). Conclusion: The age doesn't affect the hidden blood loss in elderly intertrochanteric fracture patients fixed with combined external fixator, which indicated that the operation is safe and reliable for such patients.

Abstract
Objective: To describe the status of non-steroidal anti-inflammatory drugs (NSAIDs) use in areas with a high incidence of upper gastrointestinal cancer in China. Methods: This study was based on the National Key Research and Development Program of "National Precision Medicine Cohort of Esophageal Cancer" and "Study on Identification and Prevention of High-risk Populations of Gastrointestinal Malignancies (Esophageal cancer, Gastric cancer and Colorectal cancer)" . From January 2017 to August 2018, 212 villages or communities with a high incidence of esophageal cancer or gastric cancer were selected from 12 regions in 6 provinces. A total of 35 910 residents aged between 40 and 69 years old who met the inclusion criteria and signed the informed consent were investigated and enrolled in this study. The use of NSAIDs, demographic characteristics, health-related habits, height, weight, and blood pressure were collected by the questionnaire and physical examination. The status of main NSAIDs (aspirin, acetaminophen and ibuprofen) use with the difference varying in genders, age groups and regions were analyzed by using χ(2) test and Cochran-Armitage trend analysis method. Results: Of 35 910 subjects, the mean age was (54.6±7.1) years old and males accounted for 43.42% (15 591). The overall prevalence of NSAIDs intake was 4.56% (1 638), but it significantly varied in different provinces (P<0.001). The overall prevalence of NSAIDs intake was 4.87% (1 750) in females, which was significantly higher than that in males 4.24% (1 524) (P<0.001). The prevalence of NSAIDs intake increased with age (P for trend <0.001). As the frequency of NSAIDs intake increased, the incidence of gastrointestinal symptoms, gastrointestinal ulcers and black stools increased (P for trend <0.05 for all). Conclusion: The use of NSAIDs is prevalent in some areas with a high incidence of upper gastrointestinal cancer in China. The increased use of NSAIDs may lead to more adverse effects related to the gastrointestinal tract.

Abstract
To evaluate the relationship between the aryl hydrocarbon receptor (AHR) rs2066853 gene polymorphism and the risk of male infertility. PubMed, Embase, Web of Science, and Chinese National Knowledge Infrastructure (CNKI) were searched for relevant case–control studies up to 31 July 2019. Odds ratio (OR) and 95% confidence interval (95% CI) were used to assess the strength of associations. Finally, seven case–control studies involving 1247 cases and 1762 controls were included in this meta-analysis. The pooled results showed that there was no significant association between AHR rs2066853 gene polymorphism and male infertility risk (A vs. G: OR = 1.08, 95% CI = 0.83–1.39; AA vs. GG: OR = 1.16, 95% CI = 0.65–2.04; AA vs. GA + GG: OR = 1.17, 95% CI = 0.66–2.07; AA + GA vs. GG: OR = 0.99, 95% CI = 0.85–1.15). Subgroup analysis by ethnicity showed the same result. However, significant association was found between AHR rs2066853 gene polymorphism and male infertility risk in oligoasthenotspermia (A vs. G: OR = 2.52, 95% CI = 1.72–3.70). In conclusion, our meta-analysis indicated that AHR rs2066853 gene polymorphism might be associated with an increased susceptibility to oligoasthenotspermia.

Abstract
Dual energy computed tomography (DE CT) is a promising technology for the assessment of bone compositions. One of potential applications involves evaluations of fracture healing using longitudinal measurements of callus mineralization. However, imaging of fractures is often challenged by the presence of metal fixation hardware. In this work, we report on a new simultaneous DE reconstruction-decomposition algorithm that integrates the previously introduced Model-Based Material Decomposition (MBMD) with a Known-Component (KC) framework to mitigate metal artifacts. The algorithm was applied to the DE data obtained on a dedicated extremity cone-beam CT (CBCT) with capability for weight-bearing imaging. To acquire DE projections in a single gantry rotation, we exploited a unique multisource design of the system, where three X-ray sources were mounted parallel to the axis of rotation. The central source provided high energy (HE) data at 120 kVp, while the two remaining sources were operated at a low energy (LE) of 60 kVp. This novel acquisition trajectory further motivates the use of MBMD to accommodate this complex DE sampling pattern. The algorithm was validated in a simulation study using a digital extremity phantom. The phantom consisted of a water background with an insert containing varying concentrations of calcium (50 - 175 mg/mL). Two configurations of titanium implants were considered: a fixation plate and an intramedullary nail. The accuracy of calcium-water decompositions obtained with the proposed KC-MBMD algorithm was compared to MBMD without metal component model. Metal artifacts were almost completely removed by KC-MBMD. Relative absolute errors of calcium concentration in the vicinity of metal were 6% - 31% for KC-MBMD (depending on the calcium insert and implant configuration), compared favorably to 48% - 273% for MBMD. Moreover, accuracy of concentration estimates for KC-MBMD in the presence of metal implant approached that of MBMD in a configuration without implant (6%-23%). The proposed algorithm achieved accurate DE material decomposition in the presence of metal implants using a non-conventional, axial multisource DE acquisition pattern.

Abstract
Objective: To estimate the incidence and mortality of kidney cancer in China in 2014, based on the cancer registration data. Data was collected through the National Central Cancer Registry (NCCR). Methods: All together, 449 cancer registries submitted required data on incidence and deaths of kidney cancer occurred in 2014, to the NCCR. After evaluation on the quality of data,339 registries were accepted for analysis and stratified by areas (urban/rural) and age groups. Combined with data from the National population in 2014, the nationwide incidence and mortality of kidney cancer were estimated. Data from the 2000 National census was used, and with Segi's population used for the rates of age-standardized incidence/mortality. Results: The qualified 339 cancer registries covered a total population of 288 243 347, with 144 061 915 in urban and 144 181 432 in rural areas. The percentage of morphologically verified cases and cases with only available death certificates were 72.70% and 1.27%, respectively. The mortality to incidence ratio was 0.37. The estimates of new cases were around 68 300 in whole China, in 2014, with a crude incidence rate as 4.99/100 000 (95%CI: 4.95/100 000-5.03/100 000). The age-standardized incidence rates of kidney cancer, estimated by China standard population (ASR China) and world standard population (ASR world) were 3.43/100 000 (95%CI: 3.40/100 000-3.46/100 000) and 3.40/100 000 (95%CI: 3.37/100 000- 3.43/100 000), respectively. The cumulative incidence rate of kidney cancer was 0.40% in China. The crude and ASR China incidence rates for males appeared as 6.09/100 000 (6.03/100 000-6.15/100 000) and 4.32/100 000 (4.28/100 000-4.36/100 000), respectively, whereas those were 3.84/100 000 (3.79/100 000-3.89/100 000) and 2.54/100 000 (2.50/100 000-2.58/100 000) for females. The crude and ASR China incidence rates in urban areas appeared as 6.60/100 000 (95%CI: 6.54/100 000-6.66/100 000) and 4.25/100 000 (95%CI: 4.21/100 000-4.29/100 000), respectively, whereas those were 3.05/100 000 (95%CI: 3.01/100 000-3.09/100 000) and 2.29/100 000 (95%CI: 2.25/100 000-2.33/100 000) in rural areas. The estimates of kidney cancer deaths were around 25 600 in the country, in 2014, with a crude mortality rate of 1.87/100 000 (95%CI: 1.85/100 000-1.89/100 000). The ASR China and ASR world mortality rates appeared as 1.16/100 000 (95%CI: 1.14/100 000-1.18/100 000) and 1.16/100 000(95%CI: 1.14/100 000-1.18/100 000), respectively, with a cumulative mortality rate (0-74 years old) of 0.12%. The crude and ASR China mortality rates were 2.31/100 000 (95%CI: 2.27/100 000- 2.35/100 000) and 1.52/100 000 (95%CI: 1.50/100 000-1.54/100 000) for males, respectively, whereas those were 1.41/100 000 (95%CI: 1.38/100 000-1.44/100 000) and 0.81/100 000 (95%CI: 0.79/100 000- 0.83/100 000) for females. The crude and ASR China mortality rates were 2.49/100 000 (95%CI: 2.45/100 000-2.53/100 000) and 1.42/100 000 (95%CI: 1.40/100 000-1.44/100 000) in urban areas, respectively, whereas those were 1.12/100 000 (95%CI: 1.09/100 000-1.15/100 000) and 0.78/100 000 (95%CI: 0.76/100 000-0.80/100 000) in the rural areas. Conclusions: Both the incidence and mortality of kidney cancer seemed low, in China. However, the incidence of kidney cancer had greatly increased. Our findings suggested that prevention and control strategies for kidney cancer should be focused on males in the urban areas.

Abstract
To evaluate the association between TP53 codon72 polymorphism and male infertility risk. We conducted a search on Medline, Embase, Web of Science and CNKI up to April 30, 2017. Odds ratio (OR) and 95% confidence interval (95% CI) were used to assess the strength of the association. Seven studies including 1,818 cases and 2,278 controls met the inclusion criteria. The pooled results indicated that no significant association was observed between TP53 codon72 polymorphism and male infertility risk (G versus C: OR = 1.11, 95%CI = 0.94-1.32; GG versus CC: OR = 1.26, 95%CI = 0.90-1.78; GG versus GC+CC: OR = 1.16, 95%CI = 0.90-1.49; GG+GC versus CC: OR = 1.15, 95%CI = 0.88-1.49). In the subgroup analysis by ethnicity, significant association was observed between TP53 codon72 polymorphism and male infertility risk in non-Chinese (G versus C: OR = 1.47, 95%CI = 1.14-1.89), but not in Chinese population (G versus C: OR = 1.03, 95%CI = 0.87-1.22). In conclusion, this study suggested that TP53 codon72 polymorphism might be associated with an increased susceptibility to male infertility in non-Chinese population, but not in Chinese population. Studies with larger sample sizes and representative population-based cases and well-matched controls are needed to validate our results.

Abstract
Objective: To investigate the effect of fried food intake on the pathogenesis of gastric cancer and precancerous lesions. Methods: From 2005 to 2013, the residents aged 40-69 years from 11 counties/cities where cancer screening of upper gastrointestinal cancer were conducted in rural areas of Henan province as the subjects (82 367 cases). The information such as demography and lifestyle was collected. The residents were screened with endoscopic examination. The biopsy sampleswere diagnosed pathologically, according to pathological diagnosis criteria, the subjects with high risk were divided into the groups with different pathological degrees. The multivariate ordinal logistic regression analysis was used to analyze the relationship between the frequency of fried food intake and gastric cancer and precancerous lesions. Results: The study coverd 46 425 males and 35 942 females, with a age of (53.46±8.07)years. The study collected 6 707 cases of normal stomach, 2 325 cases of low grade intraepithelial neoplasia, 226 cases of high grade intraepithelial neoplasia and 331 cases of gastric cancer. Multivariate logistic regression analysis showed that, compared with those whoeat fried food less than one time per week, fried foods intake (<2 times/week: OR=1.89, 95%CI: 1.57-2.28; ≥ 2 times/week: OR=1.91, 95%CI: 1.66-2.20) were a risk factor for gastric cancer and precancerous lesions after adjustment for age, sex, marital status, educational level, body mass index (BMI), smoking and drinking status. Conclusion: The intake of fried food is a risk factor for gastric cancer and precancerous lesions. Therefore, reducing the intake of fried food can prevent the occurrence of gastric carcinoma and precancerous lesions.

Abstract
Objective: To explore existing evidence of economic burden of esophageal cancer in China over the past 20 years. Methods: Based on PubMed, CNKI and Wanfang, literatures published from 1996 to 2015 were retrieved with the key words such as " economic burden" , "cost of illness" and so on. Then the information excerpted from those literatures were analyzed after several exclusionary procedures for non-esophageal cancer related literatures. The information about subjects and data source, methodology, main results were structurally abstracted and then analyzed. Quality assessments were conducted independently by two investigators using an 11-item instrument recommended by the Agency for Healthcare Research and Quality (AHRQ) for cross-sectional studies. All the expenditure data were calculated according to year-specific personal health care consumer price index (CPI) of China, the annual growth rate was calculated according to the average speed of growth. Results: A total of 23 studies (21 individual surveys and 2 population-based surveys) were included in the analysis, in which 12 were published over the past 5 years. Among the 21 individual surveys, 17 were hospital-based and the data were obtained through medical record review, and most of which only considered the direct medical economic burden (including the average overall expenditure per patient, per time and per diem). The median expenditure per patient during 1996-2011 ranged from 7 463 to 37 647 yuan (RMB) and the average growth rate was 7.68%. The median medical expenditure per clinical visit during 1996-2013 ranged from 6 851 to 57 554 yuan (RMB) and the average growth rate was 11.89%. The median medical expenditure per diem during 1996-2010 ranged from 225 to 1 319 yuan (RMB) and the average growth rate was 12.53%. The direct medical expenditure per clinical visit varied greatly with area, which were much higher in Beijing, Shanxi and Hubei. In both individual survey and population-based survey, less data about the direct non-medical expenditure and the influence of indirect expenditure on the economic burden were reported. Conclusion: Less data are available on economic burden of esophageal cancer in China over the past 20 years and the data's comparability are poor, especially in terms of population level or indirect burden. Direct medical expenditure is on the rise, and regional differences.

Abstract
To evaluate the association between the SPO11 gene C631T polymorphism and the risk of male infertility. We conducted a search on PubMed, Embase, Web of Science, Chinese National Knowledge Infrastructure (CNKI), China biology medical literature database (CBM), VIP, and Chinese literature database (Wan Fang) on 31 March 2016. Odds ratio (OR) and 95% confidence interval (95%CI) were used to assess the strength of associations. A total of five studies including 542 cases and 510 controls were involved in this meta-analysis. The pooled results indicated that the SPO11 gene C631T polymorphism was significantly associated with increased risk of male infertility (TT + CT vs. CC: OR = 4.14, 95%CI = 2.48–6.89; CT vs. CC: OR = 4.34, 95%CI = 2.56–7.34; T vs. C: OR = 4.35, 95%CI = 2.58–7.34). Subgroup analysis of different countries proved the relationship between SPO11 gene C631T polymorphism and male infertility risk in Chinese, but not in Iranian peoples. In conclusion, this study suggested that SPO11 gene C631T polymorphism may contribute as a genetic factor susceptible to cause male infertility. Furthermore, more large sample and representative population-based cases and well-matched controls are needed to validate our results.

Objective:To explore the clinic characters and the associated factors for the onset of the sinus fungus ball disease. Method:Analyze 52 cases who have received surgery with sinus fungus ball disease retrospectively. The effect factors of age, sex, occupation, the side of the lesion, involving sinus group number, accompany with merger polyps or not, presence of nasal septum deviation, vesicular middle turbinate, paradoxical middle turbinate, infraorbital cells,routine blood leukocyte classification, serum specific IgE, pathogenic fungi species have all been taken into consideration for statistical analysis. Result:In 52 cases of sinus fungus ball disease, 36 cases only suffered in maxillary sinus, 1 case only suffered in ethmoid sinus, 4 cases only suffered in sphenoid sinus, 7 cases suffered from two sinus lesions with the combination of maxillary sinus and ethmoid sinus in all, 4 cases fuffered from three sinus lesions with the combination of maxillary sinus, ethmoid sinus and sphenoid sinus in 2 cases, maxillary sinus, ethmoid sinus and frontal sinus in 2 cases. 26 cases have the lesion on left side,17 cases on the right side, 8 cases on both sides. Aspergillus is the main pathogenic fungus for sinus fungus ball. Maxillary sinus is the most susceptible single sinus for sinus fungus ball. Nasal polyps is commonly seen in multiple sinuses fungus ball(P<0.01). Single sphenoid sinus fungus ball is more commonly seen in the patients with diabetes mellitus(P<0.01). Lesion side of sinus fungus ball has nothing to do with the nasal anatomy abnormalities of nasal septum deviation, vesicular middle turbinate, paradoxical middle turbinate, infraorbital cells. Conclusion:The present study indicates that maxillary sinus fungus ball is the most common type for sinus fungus ball. Aspergillus is the main pathogenic fungus for sinus fungus ball. Nasal polyps is more involved in multiple sinuses fungus ball,Single sphenoid sinus fungus ball is more commonly seen in the patients with diabetes mellitus. Lesion side of sinus fungus ball has none relationship with common nasal anatomy abnormalities.

Abstract
To investigate the value and essentiality of 6- and 24-h delay hepatobiliary scintigraphy in the differential diagnosis of biliary atresia (BA), we retrospectively analyzed 197 infants (121 boys/76 girls; age range, 3-205 days; average age, 63.9 days) admitted to Jiangxi Children's Hospital for persistent jaundice (> 2 weeks), hepatosplenomegaly, and abnormal liver function. After receiving anti-inflammatory treatment and cholagogic pre-treatment for 7-10 days without a clear diagnosis, the children underwent 99mTc-labeled diethylacetanilide-iminodiacetic acid hepatobiliary scintigraphy. BA and infant hepatitis syndrome were diagnosed in 107 and 90 infants, respectively after laparoscopic cholangiography, surgical pathology, or 6-month clinical follow-up. The diagnostic efficiencies of hepatobiliary scintigraphy for BA were evaluated within 50 min and at 6 and 24 h. The areas under the receiver operating characteristic curves within 50 min, at 6 and 24 h were 0.696, 0.829 , and 0.779 , suggesting poor diagnostic value within 50 min, but improvement at 6 and 24 h. The compliance rate of 6- and 24-h imaging for BA diagnosis was 89.34% (176/197; paired chi-square test Kappa value, 0.77; P > 0.05), signifying high consistency. The diagnostic efficiency values of 6-/24-h imaging for BA diagnosis were sensitivity (90.65/89.72%), specificity (74.44/78.89%), accuracy (83.25/84.77%), positive and negative predictive values (80.83/83.48% and 87.01/86.59%), with no significant difference (P > 0.05). To provide optimal treatment in early BA, the- 6-h hepatobiliary scintigraphy had practical value, especially when combined with tomographic or dynamic imaging; 24-h delay imaging was deemed unnecessary because it was not significantly superior.

Abstract
AIMS This experiment investigated the effects of sub-chronic aluminum chloride (AlCl3) exposure on rat ovaries. MAIN METHODS Eighty female Wistar (5weeks old) rats, weighed 110-120g, were randomly divided into four treatment groups: control group (CG), low-dose group (LG, 64mg/kg BW AlCl3), mid-dose group (MG, 128mg/kg BW AlCl3) and high-dose group (HG, 256mg/kg BW AlCl3). The AlCl3 was administered in drinking water for 120days. The ovarian ultrastructure was observed. The activities of acid phosphatase (ACP), alkaline phosphatase (ALP), succinate dehydrogenase (SDH), Na(+)-K(+)-ATPase, Mg(2+)-ATPase and Ca(2+)-ATPase, the contents of Fe, Cu and Zn, and the protein expression of follicle-stimulating hormone receptor (FSHR) and luteinizing hormone receptor (LHR) in the ovary were determined. KEY FINDINGS The results showed that the structure of the ovary was disrupted, the activities of ALP, ACP, SDH, Na(+)-K(+)-ATPase, Mg(2+)-ATPase and Ca(2+)-ATPase, the contents of Zn, Fe and the protein expression of FSHR and LHR were lowered, and the content of Cu was increased in AlCl3-treated rats than those in control. SIGNIFICANCE The results indicate that sub-chronic AlCl3 exposure caused the damage of the ovarian structure, the disturbed metabolism of Fe, Zn and Cu and the decreased activities of Na(+)-K(+)-ATPase, Mg(2+)-ATPase and Ca(2+)-ATPase in the ovary, which could result in suppressed energy supply in the ovary. A combination of suppression of energy supply and reduction of expression of FSHR and LHR could inhibit ovulation and corpus luteum development, leading to infertility in female rats.

Abstract
Effect of a low dose of whole-body X-irradiation (D1 = 0.075 Gy) of mice on some biochemical changes induced in the spleen and thymus by a subsequent challenge dose (D2 = 1.5 Gy) was studied by electron paramagnetic resonance (EPR). Kunming and SHK mice were used. Concentration of ribonucleotide reductase (RR) in the spleen and thymus of unirradiated Kunming mice was 0.70 and 0.46 microM respectively, and of unirradiated SKH mice--0.37 and 0.21 microM respectively (systematic error 45%). For mice exposed only to the low dose (D1 group), a stimulating effect on RR activity in spleen and thymus was found, while in mice subjected only to the D2 dose (D2 group) activity of the enzyme in the organs decreased considerably 18 h after irradiation. The group of mice irradiated with D1 and D2 doses, given at a 6-h interval (D1 plus D2 group), showed a RR activity in the organs lower than D1 and higher than D2 groups. This finding indicates that there exists an adaptation-like response to a low-dose whole-body irradiation in murine spleen and thymus. This low 'inductive' dose makes the organs' RR less susceptible to inhibition induced by a subsequent challenge dose. Preliminary results showed that the same kind of response is probably a characteristic of the RR content of splenocytes as well as of the rate of thymidine incorporation into splenocytes. 5-Thyml radicals of DNA (TH radicals) induced in whole tissues by gamma-irradiation in vitro at 77 K were also studied. Radiochemical yield of these radicals (4.0 and 5.3 nmol j-1), for spleen and thymus respectively of unirradiated Kunming mice, and 2.3 and 2.6 nmol J-1, for spleen and thymus respectively of unirradiated SHK mice (systematic error 30%), decreased significantly in both organs upon D2 irradiation. This decrease, however, was the consequence of DNA content diminishing upon D2 irradiation rather than change of DNA radiosensitivity: the beta value of TH radicals, i.e. yield of radicals per unit mass of DNA in each organ was equal for the mice from all D1, D1 plus D2, D2 and control groups. The beta values of TH radicals in mouse spleen and thymus were of the same order of magnitude compared with the yield of the single-strand breaks of DNA measured previously in rat organs just after whole-body irradiation, i.e. about 1 x 10(2) (Gy x 10(12) Da)-1.

Abstract
A passive air sampler was developed for collecting polycyclic aromatic hydrocarbons (PAHs) in air mass from various directions. The airflow velocity within the sampler was assessed for its responses to ambient wind speed and direction. The sampler was examined for trapped particles, evaluated quantitatively for influence of airflow velocity and temperature on PAH uptake, examined for PAH uptake kinetics, calibrated against active sampling, and finally tested in the field. The airflow volume passing the sampler was linearly proportional to ambient wind speed and sensitive to wind direction. The uptake rate for an individual PAH was a function of airflow velocity, temperature and the octanol-air partitioning coefficient of the PAH. For all PAHs with more than two rings, the passive sampler operated in a linear uptake phase for three weeks. Different PAH concentrations were obtained in air masses from different directions in the field test.

Abstract
The purpose of the present study was to explore the possibility of establishing cancer radiotherapy protocols that could promote treatment efficacy at a reduced radiation dose. Mouse models of melanoma (B16) and Lewis lung carcinoma (LLC) were used in the experiments. Conventional local radiotherapy was combined with low dose whole-body irradiation (LDWBI) in the presence or absence of gene therapy by intratumor injection of a recombinant plasmid Egr-mIL-18-B7.1 (E18B). After a number of trials with different combinations it was found that a protocol of 2-week treatment with 2 x (E18B + 2 Gy + 0.075 Gy x 2) was found to be able to promote treatment efficacy at a reduced radiation dose. In this protocol local irradiation with 2Gy was administered 24h after intratumor injection of 10 microg of the plasmid E18B followed by LDWBI with 0.075 Gy every other day for 2 sessions in 1 week, and the procedure was repeated for another week. When this combined treatment was compared with conventional radiotherapy, i.e., 2Gy every other day 3 times in one week repeated for 2 weeks, the treatment efficacy was improved, as judged by increased average survival rate, reduced mean tumor weight, reduced pulmonary metastasis and suppressed intratumor capillary growth with a 2/3 reduction of radiation dose. Immunologic studies showed stimulated natural killer (NK) and cytotoxic T lymphocyte (CTL) activity as well as increased interferon-gamma (IFN-gamma) secretion in this combined treatment group as compared with the group receiving local treatment alone. It is suggested that up-regulation of host anticancer immunity by LDWBI and the initiation of expression of immune genes by both the local large dose and LDWBI are important factors in the realization of improved cancer control.

Abstract
An airtight two-chamber exposure devise was designed for investigating foliar uptake of polycyclic aromatic hydrocarbons (PAHs) by plants. The upper and the bottom chambers of the device were air-tightly separated by an aluminum foil and the plant aerial tissues and roots were exposed in the two chambers, respectively. The device was tested using maize exposed to several PAH species. Positive correlations between air and aerial tissue concentrations of the exposed PAH species were revealed. PAHs spiking in the culture solution had no influence on the leaf concentrations.

Abstract
Often, the sources of polycyclic aromatic hydrocarbons (PAHs) in environmental media can be identified by comparing the ratios of concentrations of selected pairs of PAH congeners in the source emissions to the ratios in the contaminated environmental media. However, these ratios can be altered significantly due to differences in the transport of the PAH compounds in a multimedia environment. To examine such changes, a fugacity model was applied to PAH ratios in a model environment. A linear relationship between the rate of emission and the bulk media concentration was identified for each PAH compound in an environmental medium at steady state and was quantified by a receptor-to-source ratio (RRS). It was demonstrated that the RRS values of the two congeners usually differ significantly. Consequentially, PAH ratios changed remarkably from the source emissions to various environmental media. A site-specific rectification factor (RF) was defined as the ratio of the two RRS values of the paired congeners for a specific PAH ratio in a given medium, which can be applied to account for the ratio changes in a multimedia environment. The PAH ratio changes were further verified with the surface soil data collected from Tianjin, China, and the observed changes of PAH ratios were compared favorably with the model predictions. The sensitivity analysis revealed that PAH ratios of the low molecular weight compounds were less stable. The most influential parameters controlling PAH ratios were those pertaining to dry precipitation, surface-to-air diffusion, degradation in air and water, and exchange between water and sediment.

Abstract
A number of studies have indicated that 8p22-p12 is likely to harbor schizophrenia susceptibility loci. In this region, the candidate gene of interest, neuregulin 1 (NRG1), may play a role in the pathogenesis of schizophrenia. Then in the present study, we performed the linkage disequilibrium to determine the association between three genetic variants (SNPs: rs3924999, rs2954041, SNP8NRG221533) on NRG1 gene and schizophrenia in 246 Chinese Han schizophrenic family trios using PCR-based restriction fragment length polymorphism method and denaturing high-performance liquid chromatography. The transmission disequilibrium test analysis for each variant showed a significant difference between two transmitted alleles even after Bonferroni correction (rs3924999, P=0.007752; rs2954041, P=0.0009309; SNP8NRG221533, P=0.012606). The global chi(2) test for haplotype transmission also revealed a strong association (chi(2)=46.068, df=7, P&<0.000001). Our results suggest that the NRG1 gene may play a role in conferring susceptibility to the disease.

Abstract
OBJECTIVE To establish through analysis of the radial pressure pulse waveform the dose dependent effects of glyceryl trinitrate (GTN) on properties of different blood vessels. DESIGN Radial pulse waveform was measured in randomised order before, during a five hour application of a GTN patch delivering 0.104-0.625 mg/h, and for two hours after patch removal. The radial pressure waveform (Millar applanation tonometer) was convolved into an ascending aortic wave using a generalised transfer function (SphygmoCor process) enabling measurement of aortic systolic, diastolic, pulse, mean, and augmented pressure and left ventricular ejection duration in addition to standard brachial cuff pressures. SETTING Fu Wai and Ren Ming hospitals in Beijing, China. PATIENTS 46 recumbent hospitalised patients aged 56 (9) years, awaiting electrophysiological or other diagnostic studies, fasting, and with other treatments suspended. MAJOR OUTCOME MEASURES Conventional brachial pressure measures and data from the synthesised aortic pulse. RESULTS There was no consistent change in heart rate or brachial pressures except for a decrease in systolic and pulse pressures (p < 0.01) at dose > 0.416 mg/h. In contrast, there were substantial and significant (p < 0.0001) decreases in aortic systolic, pulse, and augmented pressures at all doses, mean pressure (p < 0.001) at doses > 0.416 mg/h, and ejection duration (p < 0.001) at doses > 0.208 mg/h. CONCLUSIONS Pulse waveform analysis exposes dose dependent effects of GTN on the aortic waveform, suggesting muscular conduit arterial dilatation with reduced wave reflection at the lowest dose, arteriolar dilatation and decreased peripheral resistance at the highest dose, and venous dilatation at the intermediate dose.

Abstract
OBJECTIVE To evaluate the efficacy of excimer laser photorefractive keratectomy(PRK) on myopia and myopia astigmatism. METHODS PRK was performed with VISXC20/20 on 377 eyes of 209 patients. Treated eyes were divided into two groups, according to their conditions before operation: Group I included 238 eyes (-1.50 to -6.00 D); Group II, 139 eyes (-6.25 to -16.00 D). All patients were followed-up for more than three years. RESULTS Percentages of uncorrected visual acuity (UCVA) > or = 10/20 and 20/20 were 99.6% and 85.3% in Group I, and 79.9% and 48.2% in Group II respectively. Percentage of diopter < +/- 1.00 in Group I was 94.5%, and 61.9% in Group II. The rate of corneal haze of grade 0 was 100% in Group I, and 98.6% in Group II, but corneal haze of grade 2 was found in 1.2% of eyes in Group II. The postoperative intraocular pressure (IOP) of all operated eyes was normal. CONCLUSION The results suggest that excimer laser PRK is an effective method for treating myopia and myopic astigmatism, especially for low and moderate myopia.

Abstract
OBJECTIVE To investigate the molecular regulation of G1 arrest of mouse thymocytes induced by ionizing radiation. METHODS Cell cycle was analyzed by flow cytometry (FCM) following staining of cells with propidium iodide. Fluorescent staining and flow cytometry analysis were employed for measurement of protein expression. RESULTS It was demonstrated that G1 phase of mouse thymocytes increased significantly at 12 h after whole body irradiation (WBI) with the doses of 0.5, 1.0 and 2.0 Gy, and at 24 h following 2.0 Gy exposure, measured by FCM. In the time course experiment, it was found that G1 phase of thymocytes increased significantly at 4 h, reached a peak level at 24 h and came down toward 48 h after WBI with 2.0 Gy X-rays. The results also showed that after 2.0 Gy exposure, the expression of proteins in mouse thymocytes increased significantly from 1 h to 8 h for p53, for p21 from 4 h to 48 h, and for MDM2 at 4 h and 8 h, measured by FCM. But no change was found for GADD45 protein expression. CONCLUSION These results suggest that G1 arrest could be induced by a single dose of 0.5 Gy, 1.0 Gy or 2.0 Gy, and its molecular control might be established through the p53-p21 pathway.
