Abstract
PURPOSE/OBJECTIVE(S) Bone marrow sparing intensity modulated radiotherapy (BMS-IMRT) can reduce the incidence of acute hematologic toxicity (HT) for locoregionally advanced cervical cancer (LACC) patients receiving concurrent chemoradiotherapy (CCRT), but the norm has been controversial. The purpose of the study was to evaluate the effects of bone marrow (BM) V40 <25% on decreasing the incidence of acute HT in a prospective clinical trial. MATERIALS/METHODS A total of 242 LACC patients were recruited from May 2021 to May 2022, who were evenly randomized into BMS-IMRT group and standard IMRT group according to a computer-generated random number list. All patients received pelvic irradiation with concurrent cisplatin (40 mg/m2 weekly), followed by brachytherapy. For patients in BMS-IMRT group, the outer contour of pelvic bone, lumbar spine and left and right femur heads were additionally delineated as a surrogate for BM, and V40 <25% was prescribed. Blood counts were tested weekly, of which nadirs during external beam radiotherapy (EBRT) were graded to assess acute HT as primary observation index. Second observation index were dosimetric parameters of EBRT plan from the dose volume histograms (DVHs). Binary logistic regression model and receiver operating characteristic (ROC) curve were used for predictive value analysis. RESULTS Baseline demographic, disease and treatment characteristics were all balanced between BMS-IMRT group and standard IMRT group. BMS-IMRT was associated with a lower incidence of grade ≥2 and grade ≥3 acute HT, leukopenia and neutropenia (72.70% vs 90.90%, P <0.001*; 16.50% vs 65.30%, P <0.001*; 66.10% vs 85.10%, P = 0.001*; 13.20% vs 54.50%, P <0.001*; 37.20% vs 66.10%, P <0.001*; 10.70% vs 43.80%, P <0.001*). Plan target volume (PTV) for all patients satisfied the clinical requirement of V(100%) ≥95%, and conformity and homogeneity were both comparable between 2 groups. BMS also decreased dose delivered to the organs at risk (OARs) including rectum, bladder and left and right femur head. Univariate and multivariate analyses showed that BM V40 was an independent risk factor for grade ≥3 acute HT (odds ratio [OR] = 2.734, 95% confidence interval [CI] = 1.959-3.815, P <0.001*). Cutoff value was 25.036% and area under the curve (AUC) was 0.786. The nomogram was constructed, which was rigorously evaluated and internally cross-validated, showing good predictive performance. CONCLUSION BM V40 <25% can reduce the risks of acute HT for LACC patients receiving CCRT while the dose delivery of target volume and other normal tissues were not compromised. With great practicality and applicability, BM V40 <25% is a promising strategy, making BMS-IMRT widespread especially in the area where application of image guided radiotherapy (IGRT) such as 18F-fluorodeoxyglucose positron emission tomography (18FDG-PET)/CT is not popularized.

Abstract
To provide references for the diagnosis and treatment of congenital granular cell tumor (CGCT), by comprehensive analysis of the clinical data, histopathological and immunohistochemical results. Patients with CGCT were involede, from March 2015 to November 2020, at the Department of Oral and Maxillofacial Surgery of the First Affiliated Hospital of Zhengzhou University. A total of 6 children, aged 3-16 days, 1 male and 5 female, 5 maxillary and 1 mandibular, with maximum tumor diameter of 6-70 mm, were included. The lesions of CGCT were single and connected to the alveolar ridge by a pedicle. The surface of the tumor was covered with a vascular network, and two cases had ulcers on the surface of the tumor. All 6 cases had the tumor removed surgically and there was no recurrence or metastasis in the follow-up visit. Although CGCT is rare, it is a benign tumor and generally does not recur or metastasize after surgery, and has a good prognosis. The prenatal imaging, clinical manifestations after delivery, pathological characteristics and immunohistochemical analyses may provide reference for early diagnosis and treatment of CGCT.

Abstract
OBJECTIVE To investigate heterogeneous effects of a combination of conservative therapies compared with an education comparator for thumb base (TB) osteoarthritis (OA) according to clinically relevant characteristics. METHODS Pre-planned subgroup analysis of the COMBO trial (n = 204) which compared a combination of education on self-management and ergonomic principles, a prefabricated neoprene splint, hand exercises, and diclofenac sodium gel, with education alone for radiographic and symptomatic TB OA. Primary outcomes were change in pain (visual analogue scale [VAS], 0-100 mm) and hand function (Functional Index for Hand Osteoarthritis questionnaire, 0-30) from baseline to week-6. Other outcomes were grip and tip-pinch strength and patient's global assessment (PGA) (VAS, 0-100 mm). Possible treatment effect modifiers were the presence of interphalangeal joint pain, erosive hand OA, radiographic thumb carpometacarpal joint subluxation (higher vs equal or lower than the sample mean), and baseline radiographic OA severity (Kellgren Lawrence grade). Linear regression models were fitted, adding interaction terms for each subgroup of interest. RESULTS The treatment effects of the combined intervention at 6 weeks were greater in participants with lower joint subluxation compared with those with greater subluxation (pain -11.6 [95%CI -22.2, -9.9] and 2.6 [-5.5, 10.7], respectively, difference between the subluxation groups 14.2 units (95% CI 2.3, 26.1), p-value 0.02; and PGA -14.0 [-22.4, -5.5] and 1.5 [-6.2, 9.3), respectively, difference between the subluxation groups 15.5 units (95% CI 4.2, 26.8), p-value 0.03). There was no statistically significant heterogeneity for the other subgroups. CONCLUSION A combination of conservative therapies may provide greater benefits over 6 weeks in individuals with lower joint subluxation, although the clinical relevance is uncertain given the wide confidence intervals. Treatment strategies may need to be customized for those with greater joint subluxation. TRIAL REGISTRATION NUMBER ACTRN 12616000353493.

Abstract
Objective: To analyse the quality of life of patients receiving repair of bone defect with folded fibula flap after removal of mandibular ameloblastoma. Methods: The case data of 39 patients with ameloblastoma admitted to the First Affiliated Hospital of Zhengzhou University from August 2013 to April 2016 were retrospectively analysed, including 21 males and 18 females, from 18 to 58 years old. 3D printing and digital technology were used in flap preparation before surgery in all patients. The folded fibular flaps were used to repair mandibular defects and the implants were placed between 6-9 months after surgery. The short form-36 health survey questionnaire (SF-36) and the university of Washington quality of life questionnaire (UW-QOL) were applied to evaluate the quality of life of patients before surgery and at 6 months and 24 months after surgery. The higher the score, the better the condition. SPSS 20.0 was adopted for statistical analysis. Results: The SF-36 survey showed that the mean score of body role before surgery (72.4±11.7) was significantly higher than that at 6 months after surgery (39.6±11.1, t=23.580, P<0.05) or that at 24 months after surgery (59.8±6.4, t=8.358, P<0.001). Compared with the preoperative mean scores of Physical Pain (73.0±11.0), General Health (73.4±10.4) and Health Changes (79.2±3.9) before surgery, the mean scores Physical Pain (53.1±7.7), General Health (53.5±7.5) and Health Changes (63.9±11.7) at 6 months after surgery were decreased significantly respectively (t=13.068, 13.756 and 10.880, respectively, all P<0.05), but the mean scores Physical Pain (78.8±14.0), General Health (80.9±12.6) and Health Changes (84.4±4.6) at 24 months after surgery were increased significantly respectively (t=-2.904, -4.027 and -7.586, respectively, all P<0.05), with significant differences in the mean scores of Physical Pain, General Health and Health Changes between 6 and 24 months after surgery (t=-14.241, -16.490, -14.294, respectively, all P<0.001). The UW-QOL survey showed that the mean scores of chewing, language and taste functions decreased at 6 months after surgery (53.1±6.7, 53.0±7.7 and 62.2±9.9, respectively), but improved at 24 months after surgery (67.9±3.9, 63.9±2.9 and 68.4±11.1, respectively), with statistically significant difference (t=-16.765, -11.675 and 2.498, respectively, all P<0.001). Conclusion: The application of folded fibula flaps to repair bone defects after sugery of mandibular ameloblastoma can better meet the needs of language and chewing functions and improve the quality of life of patients.

Abstract
Objective: To summarize the clinical and pathological features of intravascular NK and T cell lymphoma for better understanding of such disease to reduce misdiagnosis and miss-diagnosis. Methods: Clinical and pathological features were analyzed retrospectively in one case of intravascular peripheral T-cell lymphoma, not otherwise specified (IVPTCL, NOS) , with literatures review. Results: The case presented in this study was a 66-year-old man. PET/CT scan showed multiple lymph nodes enlargement throughout the body. Normal lymph node structure could not be observed by tissue biopsy, while lymph follicles were partially disrupted. High-power light microscope revealed a large number of blood vessels with diffuse proliferation and dilation, where atypical lymphoid cell mass was restricted in the lumen and partially infiltrated the large blood vessel wall. These tumor cells were medium to large with moderate cytoplasm. The nucleus was irregular, single or multiple nucleoli could be seen, chromatin was condensed, some were empty and bright, and mitotic figures could be seen. Immunohistochemical staining showed that the neoplastic cells were positive for expression of CD3, CD43, CD8, GrB, TIA-1 and perforin. EBER in situ hybridization result was negative. Polymerase chain reaction test identified a clonal gene rearrangement of T-cell receptor γ. The patient was treated with CHOP in combination with chidamide, but died of infection and cardiopulmonary failure within 2 months. 56 cases of intravascular NK/T cell lymphoma with definite classification were collected from relevant literatures, including 47 cases with nasal type of extranodal NK/T cell lymphoma (27 were male and 20 were female) , 8 cases with anaplastic large cell lymphoma (3 males and 5 females) , and only one case with de nova IVPTCL, NOS in brain. We report the second case of IVPTCL,NOS, and notably originated from lymph node for the first time. Conclusions: Intravascular NK/T cell lymphoma is a highly aggressive disease with no effective treatment at present. Involvement of Lymph node has rarely been reported, and further studies on more cases are necessary.

Abstract
To explore the feasibility of using the posteromedial thigh flap as an alternative source for oral and maxillofacial reconstruction. During January 2019 to January 2020, twenty-three patients underwent oral and maxillofacial tumor ablation and defect reconstruction with 23 posteromedial thigh flaps were enrolled in the Department of Oral and Maxillofacial Surgery, The First Affiliated Hospital of Zhengzhou University. Thirteen of the patients were male and ten were female, with age of (54.5±9.7) years (33-72 years). The numbers and types of perforators, the dimension of flap and the vascular pedicle length were measured. The outcomes of flaps and donor-site complication were recorded. The patients' satisfaction with donor-site cosmesis were evaluated by the visual analogue scale (VAS). More than one sizable perforators was found in each case and the median number of perforators was 2 (range, 1 to 4), and all of the perforators were musculocutaneous. The pedicle length was (9.8±1.5) cm (range, 7.3 to 13.4 cm). The diameters of artery and the larger vein were 2.0 mm (range, 1.5 to 2.5 mm) and 2.0 mm (range, 1.5 to 3.0 mm), respectively. The dimension of the flaps ranged from 8 cm×6 cm to 12 cm×8 cm, and the donor sites were all closed primarily. All of the flaps were clinically survived, only one patient experienced partial wound dehiscence of donor site 14 days postoperatively and no donor site infection or permanent muscular weakness was reported. The VAS scores of the patients' satisfaction with donor-site cosmesis were all more than 8. The perforators of the posteromedial thigh flap is consistent and the donor-site scar is well concealed, which make the posteromedial thigh flap an excellent option for oral and maxillofacial reconstruction.

Abstract
Objective: To explore the value of neuroendoscopy combined with fluorescence angiography in anterior circulation aneurysm clipping. Methods: A total of 15 patients with anterior circulation aneurysm from Department of Neurosurgery, Zhongnan Hospital of Wuhan University between October 2018 and January 2019 were enrolled. Neuroendoscopy combined with indocyanine green fluorescence angiography (ICGA) was used to determine the shape of the aneurysm, the specific location of the aneurysm neck and its relationship with the aneurysm-bearing artery during anterior circulation aneurysm clipping. Meanwhile, Neuroendoscopy combined with ICGA can be employed to observe whether there was stenosis and incomplete clamping of the aneurysm-bearing artery after clipping the aneurysm, and whether there was misclamping of the perforating branches hidden under the posterior wall of the aneurysm. Results: The success rate of aneurysm clipping in 15 cases was 15/15. After aneurysm clipping, ICGA and neuroendoscopy were performed. The residual aneurysm neck was detected in 3 cases, and the position of aneurysm clip was adjusted or aneurysm clips were added. In one case, the anterior choroidal aneurysm was found to be mistakenly clipped. After adjusting the aneurysm clip, ICGA and neuroendoscopy showed that the anterior choroidal artery was normal. In another case, the A1 segment aneurysm was clipped. ICGA and neuroendoscopy found that the perforating branch blood vessels were mistakenly clipped. After the adjustment of the aneurysm clip, the blood vessels recovered their patency. There were no surgical-related deaths, disability and coma cases in the study. Conclusions: During aneurysm clipping, neuroendoscopy combined with ICGA can reduce cerebral vasospasm, decrease the misclipping rate of perforation of blood vessels, and avoid residual neck of aneurysm, stenosis or occlusion of aneurysm-bearing artery by using neuroendoscopy to observe whether misclipping of the perforating branch vessels exist and whether the aneurysm is clipped. Therefore, it can reduce postoperative complications.

Abstract
Objective: To investigate the incidence and risk factors of ventilator-associated pneumonia (VAP) in neonatal intensive care unit (NICU), and to provide evidence for the prevention and control of VAP. Methods: A total of 1 872 neonates, who were admitted into NICU of Hunan Provincial Maternal and Child Health Hospital and subjected to mechanical ventilation from October 2016 to June 2018, were enrolled in the study. The neonates who met the diagnostic criteria of VAP were selected as the case group, and those who were treated with ventilator for 48 hours at the same time were regarded as the control group. Multivariate logistic regression model was used to analyze the related factors of VAP. Results: Of the 1 872 neonates who underwent the mechanical ventilation, the VAP occurred in 160 cases with the incidence rate of 8.5% (160 cases). The 227 specimens were collected. Gram-positive bacteria (n=116, 51.1%) were the main pathogens. The main pathogens were Staphylococcus epidermidis, Enterococcus faecalis, Acinetobacter baumannii. By Chi-square test, birth weight, birth age, Apgar score, duration of ventilator, and whether newborn mothers with pregnancy hypertension were influencing factors. The result of logistic regression analysis showed that compared with no pregnancy included hypertension, the first aid measure at birth was initial resuscitation, and the MV time ≤ 5 days, the risk factors of ventilator-associated pneumonia in neonates included: their mothers with hypertensive disorders complicating pregnancy, using of tracheal intubation and ventilator time more than 5 days. Conclusion: The incidence of VAP in neonates receiving continuous MV therapy in neonatal intensive care unit is higher. Gram-positive bacteria are the main pathogens. VAP in neonates is related to whether newborn mothers with pregnancy hypertension, MV duration and tracheal intubation.

Abstract
Objectives: Our objective was to evaluate the association of weather factors with the risk of pain exacerbations in people with symptomatic hip osteoarthritis (OA). Method: Eligible participants with symptomatic hip OA were instructed to log on to the study website and complete questionnaires every 10 days and additionally whenever they considered they were experiencing a pain exacerbation (case period) during the 90 day follow-up. Pain exacerbation was defined as an increase of two points in pain intensity on an 11-point numeric rating scale (0-10) during the follow-up compared with baseline. Each case period was anchored to four control periods within a 35 day interval using a time-stratified approach. Weather data were obtained for both periods from the publicly available meteorological database of the Australian Bureau of Meteorology. We examined the association of weather factors across 72 h before the index date with the risk of pain exacerbation, using conditional logistic regression. Results: Among 252 participants recruited, 129 participants had at least one episode of pain exacerbation and were included in the analysis. A significant dose-response relationship was found between average daily temperature variation in the prior 72 h and risk of pain exacerbations (p = 0.04 for linear trend). There was no significant association between maximum daily temperature, minimum daily temperature, relative humidity, precipitation, or barometric pressure and hip pain exacerbations. Conclusion: The overall results suggest that only daily temperature variation among different weather factors was associated with hip pain exacerbations in people with symptomatic hip OA.

Abstract
Objective: To investigate the strong expression (S+) of P53 and BCL2 proteins in MYC/BCL2 double-expression DLBCL (DEL) and whether they can be used for the prognostic evaluation and stratified diagnosis of DELs. Methods: Tissue microarray were made by filed FFPE blocks of 174 DLBCL cases. The translocation of MYC, BCL2 and BCL6 genes were detected by FISH, and the proteins were detected by IHC. Data of clinicopathologic features and follow up of patients were collected and OS (overall survival) and PFS (progression free survival) were analyzed by statistics. Results: Eight double-hit lymphomas (DHLs) were identified in all cases, and 45 DELs were selected from 166 remaining cases, which have no significant difference in OS and PFS compared with non-DEL cases (P=0.668 and P=0.790) . Of 42 DEL-cases with follow up data, 24 cases with P53+ or/and BCL2 (S+) are significantly shorter OS and PFS than others (P=0.003 and P=0.000) , in which the cases with P53+/BCL2 (S+) co-expression were the worst prognosis, and P53/BCL2 co-weaker positive DEL cases even have superior OS and PFS than those non-DELs. Although statistics showed that the cases of P53+ or/and BCL2 (S+) have a lower OS and PFS in total cases (P=0.063 and P=0.024) , it is not the case when the DEL-cases take out from total cases, that is the cases with P53+ or/and BCL2 (S+) are as similar OS and PFS as others in non-DEL group (P=0.590 and P=0.550) . Conclusion: The strong expression of P53 and BCL2 proteins can be used as indicators of stratified diagnosis and poor prognosis of DEL.

The Maytenus compound tablet as traditional Chinese compound medicine has been approved for alleviating hyperplasia of mammary glands, whether it can inhibit cancer still unknown. The study was to evaluate the anticancer activity of the Maytenus compound tablet. Methods MTS assay evaluated the anti-proliferation effect of the Maytenus compound on H226, A2058, 786O and HeLa cancer cells and two normal epithelial cell lines, namely, 16HBE and Hecate. Nude mouse xenograft tumor model using H226 and HeLa cells examined the drug’s anticancer effect in vivo. Western blot assay studied the possible mechanism. Results The Maytenus compound indicated obvious ability to against proliferation in four strains of cancer cells, particularly against H226 cells by an IC50 of 85.47±10.06 µg/mL and against HeLa cells by an IC50 of 128.74±17.46 µg/mL. However, it had a low cytotoxicity in human normal epithelial cell lines 16HBE with an IC50 of 4,555.86±25.21 µg/mL and Hecate with an IC50 of 833.56±181.88 µg/mL. The Maytenus compound at the 2.45 g/kg oral dosages inhibited the proliferation of H226 cells and HeLa cells in nude mouse with inhibitory rates of 36.06% and 26.45%, respectively, and no organ toxicity. The Maytenus compound could significantly downregulate the expression of pEGFR, pPI3K, pAKT, pGSK3β, β-catenin, and c-MYC and upregulate the protein expression of GSK3β. Conclusions The Maytenus compound has significant anticancer activities against human cancer H226 and HeLa cells both in vitro and in vivo, highlighting it may be an anticancer medicine.

Abstract
Whole sections are important for investigation in situ of the development of cell morphology and accumulation of storage substance in cereal kernels. We developed an improved, simple method to obtain good quality whole histological sections of wheat grains during mid- and late-stage (28 and 35 days post anthesis) grain filling. The wheat grains were fixed and dehydrated, cleared in chloroform for 3 days and infiltrated in paraffin at 55° C for 3 - 5 days. The infiltrated grains then were embedded in paraffin wax, softened using diethyl pyrocarbonate (DEPC) water before sectioning. After these treatments, the wheat grains can be sectioned easily at 10 - 25 μm while retaining the cellular structure and antigenicity. The cell structure, cell distribution, autofluorescence, starch accumulation and localization in situ of bam1, one of the genes encoding β-amylase transcripts in the sections of the late developing wheat grain were observed readily.

Abstract
Objective: To evaluate the quality of life (QOL) of patients who underwent resection of mandible and reconstruction by fibula flap. Methods: A total of seventy six patients who underwent resection of mandible and reconstruction by fibula flap admitted to The First Affiliated Hospital of Zhengzhou University from January 2013 to August 2016 were prospectively analyzed. In the preoperative and postoperative 3 month, 12 months, the QOL of these patients were assessed by using the 14-item oral health impact profile questionnaires (OHIP), The University of Washington quality of life (UW-QOL) and the European organization for research and treatment of cancer quality of life questionnaire head and neck module (EORTC-QLQ-H&N). Results: The OHIP-14 questionnaire showed the highest score of the three months after surgery was mental discomfort (73.0±11.9) and psychological disorder (72.1±11.9), and it was difficult to be relieved over time. In the 12 months after surgery, the lowest scores were physiological pain (35.0±8.6) and disability (37.5±10.2), and 87% (66/76) patients thought that the flap repair worked well. The UW-QOL questionnaire showed that the scores of the patients' chewing, taste and salivary were significantly reduced by 3 months after the operation, and they were still unable to recover to preoperative level 12 months after surgery. The EORTC-QLQ-H&N35 questionnaire showed that swallowing, language, and diet scored higher in the three months after surgery, but could be restored to preoperative levels 12 months after surgery. The score was higher in 12 months after the operation than before surgery and was related to radiotherapy in some patients. Conclusions: Using fibula flap to repair the mandible defect can restore the patient's jaw function and improve the quality of life of the patients.

Abstract
Aims The aim of this study was to investigate the changes in femoral trochlear morphology following surgical correction of recurrent patellar dislocation associated with trochlear dysplasia in children. Patients and Methods A total of 23 patients with a mean age of 9.6 years (7 to 11) were included All had bilateral recurrent patellar dislocation associated with femoral trochlear dysplasia. The knee with traumatic dislocation at the time of presentation or that had dislocated most frequently was treated with medial patellar retinacular plasty (Group S). The contralateral knee served as a control and was treated conservatively (Group C). All patients were treated between October 2008 and August 2013. The mean follow-up was 48.7 months (43 to 56). Axial CT scans were undertaken in all patients to assess the trochlear morphological characteristics on a particular axial image which was established at the point with the greatest epicondylar width based on measurements preoperatively and at the final follow-up. Results Preoperatively, there were no statistically significant differences between the trochlear morphology in the two groups (sulcus angle, p 0.852; trochlear groove depth, p 0.885; lateral trochlear inclination, p 0.676; lateral-to-medial facet ratio, p 0.468; lateral condylar height, p 0.899; medial condylar height, p 0.816). Many radiological parameters of trochlear morphology were significantly different between the two groups at the final follow-up, including well-known parameters, such as the mean sulcus angle (Group S, 146.27° (sd 7.18); Group C, 160.61° (sd 9.29); p < 0.001), the mean trochlear groove depth (Group S, 6.25 mm (sd 0.41); Group C, 3.48 mm (sd 0.65); p < 0.001) and the mean lateral trochlear inclination (Group S, 20.99° (sd 3.87); Group C, 12.18° (sd 1.85); p < 0.001). Lesser known parameters such as the ratio of the lateral to medial trochlear length (Group S, 1.46 (sd 0.19); Group C, 2.14 (sd 0.42); p < 0.001), which is a measurement of facet asymmetry, and the lateral and medial condylar height were also significantly different between the two groups (p < 0.001). Conclusion The femoral trochlear morphology can be improved by early (before epiphyseal closure) surgical correction in children with recurrent patellar dislocation associated with femoral trochlear dysplasia.

Abstract
OBJECTIVE We report a minority of cases presented with abdominal pain due to intermittent hydronephrosis, to improve the recognition of this condition. PATIENTS AND METHODS We retrospectively studied 1152 children complained of abdominal pain in our center from January 2010 to December 2015. Also, we analyzed the clinical presentation, treatment experience, examination results, and image features in detail. RESULTS 14 patients received a diagnosis of intermittent hydronephrosis including 11 boys and 3 girls. 9 patients were affected on the left kidney and other 5 on the right side. All children presented recurrent abdominal pain, and the ultrasound images varied during different stages. All patients had been misdiagnosed and delayed treatment. CONCLUSIONS Abdominal pain caused by intermittent hydronephrosis is easily misdiagnosed; all preschool children with a history of recurrent abdominal pain should be suspected of this condition.

Abstract
Objective: To evaluate the quality of life (QOL) of patients who underwent resection of tongue base cancer and reconstruction by anterolateral thigh perforator free flap(ALTFF). Methods: A total of 77 patients with tongue cancer who underwent glossectomy and reconstruction by ALTFF were retrospectively analyzed in this work. At intervals of 3-month before operation, as well as both 3-month and 12-month post-operation, the QOL of these patients was assessed by using the 14-item Oral Health Impact Profile questionnaires(OHIP-14) and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck Module(EORTC-QLQ-H&N35). Results: The OHIP-14 questionnaire showed the physiological pain can be significantly alleviated at 3 months postoperatively. The highest score were psychological discomfort and psychological disorders at 3 months postoperatively. Functional limitations cannot be restored to preoperative level at 12 months postoperatively, although lower than that in 3 months postoperatively(40.6±10.3 vs 39.2±10.6, t=-0.812, P=0.948). The EORTC-QLQ-H & N35 survey showed that swallowing, language and diet were higher at 3 months postoperatively, and improved significantly at 12 months postoperatively. Teeth and mouth opening was lower before and after surgery, and no significant difference was observed. Conclusion: The use of ALTFF to repair tongue base cancer, can restore the patient's appearance, language and chewing function of the basic needs and improve the quality of life of patients.

Abstract
The study of rare genetic diseases provides valuable insights into human gene function. Here, we investigate dominant Robinow syndrome (RS), which affects the WNT5A signaling pathway. Autosomal dominant RS is caused by missense mutations in WNT5A or nonsense mutations in the adaptor protein DVL1 or DVL3. The recessive form of the disease is caused by loss-of-function mutations in the receptor ROR2. RS is characterized by hypertelorism, midface, and mandibular hypoplasia. Here, we focus on the missense mutations in WNT5A, since the impact on function is difficult to predict from in silico analysis. We used chicken embryo to express wild-type or 2 mutant versions of human WNT5A in the mandible and then examined the morphologic, cellular, and molecular effects. The 3 experimental viruses—wt WNT5A, WNT5AC83S, or WNT5AC182R—all caused shortening of the mandible on the injected side as compared with GFP controls. Although the phenotypes initially appeared similar, we uncovered specific disruption of chondrocyte polarity and shape, inhibition of cell migration, differences in target gene expression, and absence of JNK signaling only in the presence of mutant viruses. In addition, the missense mutations do not appear to block receptor binding, since in paracrine experiments, the mutant protein inhibits cell migration. In this study, we ruled out a straightforward gain or loss of function caused by the WNT5A missense mutations. Instead, the mutations are likely redirecting WNT signaling away from JNK-PCP toward other noncanonical pathways. We conclude that in RS, WNT5A missense mutations have dominant neomorphic effects that interfere with the function of the wild-type protein.

Abstract
OBJECTIVE To analyze the expression of profilin-1 in endothelial cells of rats with acute myocardial infarction. MATERIALS AND METHODS Twenty adult male Wistar rats were randomly divided into the myocardial infarction (model) group (n=10) and sham-operation (control) group (n=10). The expression of profilin-1 and phosphorylated extracellular signal kinase (pERK1/2) in aortic endothelial cells, indexes of endothelial injury [levels of endothelial microparticles (EMPs) and nitric oxide (NO)], indexes of myocardial injury [cardiac troponin T (cTnT) and creatine kinase-MB (CK-MB)], and mRNA levels of myocardial apoptotic factors (P53, Fas, Bax, and Bcl-2) in rats between the two groups were compared. RESULTS The expression of profilin-1 and pERK1/2 in aortic endothelial cells of rats in the model group was higher than in the control group (p<0.05), the levels of EMPs were increased, and NO levels were lower (p<0.05); cTnT and CK-MB in myocardial tissue, and mRNA of pro-apoptotic factors (P53, Fas, and Bax) were increased, whereas Bcl-2 mRNA was decreased (p<0.05). The protein expression of profilin-1 and pERK1 was positively correlated with the levels of cTnT, CK-MB, EMP, P53, Fas, and Bax, and negatively correlated with the levels of NO and Bcl-2 (p<0.05). CONCLUSIONS The high expression of profilin-1 is an important mechanism of acute myocardial infarction, and is expected to become a new target for the treatment of myocardial infarction.

Abstract
Objective: To evaluate the quality of life (QOL) in elderly patients with tongue cancer who underwent immediate free flap reconstruction surgery. In addition, the efficacy of the anterolateral thigh perforator free flap (ALTFF) and the radial free forearm flap (RFFF) for reconstruction was compared in patients with glossectomy. Methods: Ninty-eight patients undergoing complete or partial glossectomy and reconstruction with free flaps were grouped according to flap type. Oral functions were assessed using The University of Washington Quality of Life (UW-QOL), and the 14-item Oral Health Impact Profile questionnaires (OHIP-14) at 6 and 12 months after reconstructive surgery. Results: Eighty-six of 98 questionnaires (88%) were returned. There was significant difference between the 2 groups in the style of resection (P<0.05). For all oral function domains, the score improved progressively after the operation (6 and 12 months after the procedure). The UW-QOL questionnaire showed a significant difference between the 6 months postoperatively (ALTFF: 290.0 ± 7.8, RFFF: 236.6 ± 24.2) and 12 months postoperatively (ALTFF: 302.0±21.1, RFFF: 331.1±20.4) (P<0.05). The OHIP-14 questionnaire showed a total score of ALTFF (422.0± 15.2) which was significantly less than RFFF (434.0±38.7) at 6 months postoperatively (P<0.05). There were no meaningful differences between the 2 flap types for all oral function domains at 12 months. Conclusions: Using the RFFF or ALTFF for reconstruction of tongue defects after cancer resection influences oral function. There was no significant difference in quality of life between the two flaps at 12 months postoperatively.

Abstract
Litter size affects profitability in the swine industry. Mammalian ovaries play important roles during reproduction, including ovulation and hormone secretion, which are tightly regulated by specific microRNAs (miRNAs). In this study, we investigated the effects of specific miRNAs on porcine litter size. We compared the ovarian miRNAs of Yorkshire pigs with high (YH) and low (YL) litter sizes using Solexa sequencing technology. We identified 327 and 320 miRNAs in the ovaries of YH and YL pigs respectively. A total of 297 miRNAs were co-expressed; 30 and 23 miRNAs respectively were specifically expressed in the two libraries. A total of 83 novel miRNAs were predicted; 37 specific miRNAs were obtained, of which 21 miRNAs were upregulated and 16 miRNAs were downregulated in YH compared with YL. Additionally, 19 628 and 19 250 target genes were predicted in the two libraries respectively. The results revealed that specific miRNAs (i.e., miR-224, miR-99a, let-7c, miR-181c, miR-214 and miR-21) may affect porcine litter size. The results of this study will help in gaining understanding of the role of miRNAs in porcine litter size regulation.

Abstract
Peripheral T-cell lymphomas (PTCLs) comprise a heterogeneous group of mature T-cell neoplasms with a poor prognosis. Recently, mutations in TET2 and other epigenetic modifiers as well as RHOA have been identified in these diseases, particularly in angioimmunoblastic T-cell lymphoma (AITL). CD28 is the major co-stimulatory receptor in T cells which, upon binding ligand, induces sustained T-cell proliferation and cytokine production when combined with T-cell receptor stimulation. We have identified recurrent mutations in CD28 in PTCLs. Two residues-D124 and T195-were recurrently mutated in 11.3% of cases of AITL and in one case of PTCL, not otherwise specified (PTCL-NOS). Surface plasmon resonance analysis of mutations at these residues with predicted differential partner interactions showed increased affinity for ligand CD86 (residue D124) and increased affinity for intracellular adaptor proteins GRB2 and GADS/GRAP2 (residue T195). Molecular modeling studies on each of these mutations suggested how these mutants result in increased affinities. We found increased transcription of the CD28-responsive genes CD226 and TNFA in cells expressing the T195P mutant in response to CD3 and CD86 co-stimulation and increased downstream activation of NF-κB by both D124V and T195P mutants, suggesting a potential therapeutic target in CD28-mutated PTCLs.

Abstract
Some polymorphisms of the human CETP gene are causally and significantly associated with serum lipids levels; however, the information regarding this gene in pigs is sparse. To evaluate the effects of CETP on blood lipid traits and fat deposition in pig, porcine CETP tissue expression patterns were observed by quantitative real-time polymerase chain reaction (qPCR) first. High expression was detected in liver, spleen, gluteus medius (GM) muscle and backfat. A de novo polymorphism (AF333037:g.795C>T) in the intron 1 region of porcine CETP was identified. This polymorphism was further genotyped by direct sequencing of the PCR products of 390 Wannan Black pigs, a Chinese native breed population. Association analyses at 45 and 300 days of age revealed highly significant associations between CETP genotypes and serum lipid traits. Furthermore, this polymorphism was proved to be associated with differences in liver CETP mRNA levels: pigs at 300 days of age with the TT genotype had higher levels than did those with other genotypes (P = 0.021). Additionally, analysis at 300 days of age showed that GM CETP mRNA expression correlated positively with serum lipids levels as well as with carcass backfat thickness and intramuscular fat content in GM. These results indicate that CETP is involved in serum, adipose and muscle lipid metabolism in pigs. The mechanisms underlying such relationships and their functional implications are worthy of further research.

Abstract
We investigated dexamethasone therapy for preventing delayed encephalopathy after carbon monoxide (CO) poisoning. Eighty healthy male rats were exposed to CO and randomly divided into four groups: hyperbaric oxygen treatment (H), treatment (D), combined hyperbaric and dexamethasone treatment (C), and a control (M) group in which the rats inhaled CO to coma in the hyperbaric oxygen chamber, then were removed without further treatment. Twelve rats were put into the hyperbaric oxygen chamber and treated with air for 60 min (N) group. An eight arm maze was used to evaluate cognitive and memory abilities of these mice. Serum myelin basic protein (MBP) levels were evaluated using ELISA, and magnetic resonance imaging was used to observe brain demyelination and morbidity associated with delayed encephalopathy. A sample of the hippocampus from each group was examined by light microscopy. Cognitive and memory functions decreased in the control group M. Three days after CO poisoning, the serum MBP level of each group increased significantly. On Day 10 after CO poisoning, the MBP levels in groups C and D decreased significantly, but returned to normal on Day 18. MBP levels in the M and H groups were elevated at all time points. Brain MRIs showed significant differences among C, D, H and control M groups. Hematoxylin & eosin staining of the hippocampus showed greater damage in the control M and H groups. Early dexamethasone treatment may be useful for preventing delayed encephalopathy after CO poisoning and may reduce serum MBP levels.

Abstract
The median survival of patients with mantle cell lymphoma (MCL) ranges from 3 to 5 years with current chemotherapeutic regimens. A common secondary genomic alteration detected in MCL is chromosome 13q31-q32 gain/amplification, which targets a microRNA (miRNA) cluster, miR-17∼92. On the basis of gene expression profiling, we found that high level expression of C13orf25, the primary transcript from which these miRNAs are processed, was associated with poorer survival in patients with MCL (P=0.021). We demonstrated that the protein phosphatase PHLPP2, an important negative regulator of the PI3K/AKT pathway, was a direct target of miR-17∼92 miRNAs, in addition to PTEN and BIM. These proteins were down-modulated in MCL cells with overexpression of the miR-17∼92 cluster. Overexpression of miR-17∼92 activated the PI3K/AKT pathway and inhibited chemotherapy-induced apoptosis in MCL cell lines. Conversely, inhibition of miR-17∼92 expression suppressed the PI3K/AKT pathway and inhibited tumor growth in a xenograft MCL mouse model. Targeting the miR-17∼92 cluster may therefore provide a novel therapeutic approach for patients with MCL.

Abstract
We report a unique case of a biopsy-proven rectal cancer exhibiting spontaneous complete regression in an extremely short period of 3 months. An 80-year-old man visited our hospital because of a positive fecal occult blood test. Colonoscopy showed a sessile polyp, about 25 mm in diameter, in the middle part of the rectum. Instead of endoscopic resection, two endoscopic biopsies were taken for histological evaluation, as an invasive cancer was endoscopically suspected.Well-differentiated invasive adenocarcinoma was revealed, and thus surgical resection was planned. At the second colonoscopy for endoscopic tattooing before surgery, the polyp was found to have unexpectedly developed into a flat lesion. Furthermore, the surgically removed specimen showed that the flat lesion had transformed to a depressed lesion, and surprisingly, no cancerous tissue was detected histologically.

Abstract
Implantable medical devices and home monitors make use of wireless radio communication for both therapeutic functions and remote monitoring of patients' vital signs. While our past work showed that lack of cryptographic protection results in disclosure of private medical data and manipulation of therapies (Halperin et al., IEEE S&P, 2008) our present work shows that even using encryption is insufficient to protect the confidentiality of patient telemetry. Our experiment analyzes the security of data traffic patterns of two sets of real medical telemetry: a corpus from PhysioNet (an online biomedical research database) and a network trace of a live disaster drill using Harvard's CodeBlue medical sensor network (Chen et al., DCOSS, 2008). Our work shows that even if a wireless medical device uses encryption, patient data can leak to unauthorized parties who need not be near the patient. Our measurements show that data packet timing information and headers distinguish the types of medical and monitoring devices even if traditional cryptographic mechanisms are used. Furthermore, the highly repetitive nature of medical data, such as ECG or respiration signals, leads to additional privacy vulnerabilities that cannot be easily mitigated by means of encryption without significant modification. Data compression technology further exposes encrypted telemetry to cryptanalysis. The information leakage of telemetry could facilitate unauthorized tracking of a patient because an ECG is known to uniquely identify a person in a predetermined group (Biel et al., IEEE I&M, 2002). Moreover, our study shows that data packet padding, encryption, authentication, and other common defenses against security threats require significant energy, storage, and computation that impose on the already scarce battery and space resources. Two of our experiments show how to automatically recover data from encrypted telemetry using Bayesian classifiers. In one experiment, we encrypted an ECG signal. By observing only the length of the digitally encrypted data, we were able to reconstruct sufficient information about the original ECG data that we determined the patient's heart rate. Using similar techniques, we recovered a leaked respiration signal that visually matches the original signal. Our findings show the weakness of using common cryptographic techniques on highly periodic and often compressed medical telemetry. Our work further discusses techniques to mitigate these security and privacy risks in wireless medical telemetry systems. However, all known techniques require extra energy, computation, and bandwidth from the medical device. The lesson learned is that encryption is not enough to protect the privacy of medical telemetry, and that reasonable assurance for security and privacy will require an energy budget. Future design of medical devices will have to make difficult tradeoffs between battery life versus security and privacy.

Abstract
BACKGROUND The addition of rituximab to combination chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP), or R-CHOP, has significantly improved the survival of patients with diffuse large-B-cell lymphoma. Whether gene-expression signatures correlate with survival after treatment of diffuse large-B-cell lymphoma is unclear. METHODS We profiled gene expression in pretreatment biopsy specimens from 181 patients with diffuse large-B-cell lymphoma who received CHOP and 233 patients with this disease who received R-CHOP. A multivariate gene-expression-based survival-predictor model derived from a training group was tested in a validation group. RESULTS A multivariate model created from three gene-expression signatures--termed "germinal-center B-cell," "stromal-1," and "stromal-2"--predicted survival both in patients who received CHOP and patients who received R-CHOP. The prognostically favorable stromal-1 signature reflected extracellular-matrix deposition and histiocytic infiltration. By contrast, the prognostically unfavorable stromal-2 signature reflected tumor blood-vessel density. CONCLUSIONS Survival after treatment of diffuse large-B-cell lymphoma is influenced by differences in immune cells, fibrosis, and angiogenesis in the tumor microenvironment.
