Abstract
Objective: To explore the effect of accurately localized mini anterolateral thigh perforator flap in repairing medium-sized skin and soft tissue defects in fingers. Methods: The study was a retrospective observational study. From December 2019 to September 2022, 15 patients with medium-sized skin and soft tissue defects who met the inclusion criteria in fingers were admitted to the Second Affiliated Hospital of Wenzhou Medical University, including 12 males and 3 females, aged 23 to 62 years. After debridement, the wounds were all accompanied by exposed tendons, bones, vessels and nerves, with an area from 4.0 cm×3.0 cm to 8.0 cm×3.5 cm. Computed tomography angiography and color Doppler ultrasonography examinations were performed on both lower limbs of the patient before surgery to accurately locate the anterolateral thigh perforators. When the flap with area from 6.0 cm×3.0 cm to 11.0 cm×4.0 cm was harvested, the flap was thinned. The artery and vein perforators of the flap were anastomosed respectively with the digital artery and dorsal metacarpal vein. If there was avulsion injury, infection, or burn in the recipient area, the main arterial and veinous vessels carried by the skin flap was anastomosed with the radial artery and accompanying vein. The lateral thigh cutaneous nerve carried by the flap was anastomosed with the stump of the digital nerve. The types of perforators of the lateral thigh artery were observed during operation and compared with the location of the vessels before operation. After operation, the survival and adverse complication of the flap were closely observed. During follow-up, the skin flap color, texture, and shape were observed; the wound healing in donor area was observed. At the last follow-up, the two-point discriminative distance of the affected finger pulp was measured, and the function of the affected finger was evaluated using the trial standard for the evaluation of functions of upper limbs of Hand Surgery Society of Chinese Medical Association, and the interphalangeal joint movement of the affected finger was observed; the patients' complaints about the adverse effects of flap resection on lower limbs were recorded. Results: During the operation, it was observed that the perforators of the flaps in 11 patients were the descending branch of the lateral circumflex thigh artery, in two patients, the perforators of skin flaps were the oblique branch of the lateral thigh artery, and the perforators in another two patients were the transverse branch of the lateral circumflex thigh artery, which were consistent with the preoperative vascular localization. After operation, all flaps survived without vascular crisis and infection. The patients were followed up for 6-12 months, the flaps had excellent color, texture, and appearance; only linear scars remained on the donor wound. At the last follow-up, the two-point discrimination distance in the finger pulp was 7-11 mm; the affected finger function was rated as excellent in 6 cases, good in 6 cases, and fair in 3 cases; the flexion and extension function of the finger was not affected; two patients complained of numbness in the lateral thigh after excision of the skin flap, and the other 13 patients had no complain of adverse complaints. Conclusions: The perforating branch in lateral thigh region can be accurately located by computed tomography angiography and color Doppler ultrasonography, accurate positioning of perforators before operation can reduce the damage to the donor area during the incision of the flap, the appearance and function of the affected finger can be restored to the maximum extent by thinning the transplanted flap and rebuilding the finger sensation. Therefore, it is an effective and reliable way to repair the medium-sized skin and soft tissue defects of fingers with the mini thigh anterolateral perforator flap.

Abstract
Objective: To analyze the association between exposure to ambient PM2.5 and its components [sulfate (SO42-), nitrate (NO3-), ammonium (NH4+), organic matter (OM), and black carbon (BC)] and psychological distress among school children and adolescents aged 9 to 18 years in China. Methods: Based on data from the 2019 Chinese National Survey on Students' Constitution and Health, 130 808 children and adolescents aged 9 to 18 years were included. Scoring and determination of higher psychological distress were based on the Kessler Psychological Distress Scale (K10), and annual average exposure data for air pollution were matched by survey location and time. We used a restricted cubic spline approach based on logistic regression to fit the associations between PM2.5, SO42-, NO3-, NH4+, organic matter, black carbon concentrations, and psychological distress. Logistic regression models were used to analyse different age, gender, BMI and physical activity subgroups to estimate the association between exposure to high levels of pollution and high levels of psychological distress in different subgroups. Results: The proportion of children and adolescents with high levels of psychological distress in China was 30.4%, with girls being higher than boys at 31.6% and 29.1%, respectively (P<0.05). A non-linear positive association existed between exposure to PM2.5, SO42-, NO3- and organic matter concentrations and higher psychological distress. As PM2.5, NO3-, NH4+, organic matter, and black carbon concentrations continued to rise, the increase in the risk of higher psychological distress slowed, while SO42- showed little change in the OR of psychological distress at lower concentrations but continued to rise at higher concentrations. PM2.5 and its components were statistically associated with psychological distress in the physically inactive group but not in the physically active group. The association between high levels of pollutants and high psychological distress was stronger among students aged 9 to 12 years compared with students aged 13 to 15 years and 16 to 18 years. Conclusions: The ambient pollutant PM2.5 and its components are associated with psychological distress in children and adolescents aged 9 to 18 years in China. High pollutant exposure is a risk factor for high psychological distress among physically inactive children and adolescents, and there are age differences in the association between PM2.5 and components and psychological distress.

Abstract
Objective: To compare the differences in clinical symptoms and the time required for diagnosis of benign paroxysmal positional vertigo (BPPV) between older patients and young and middle-aged patients in the structured inquiry of dizziness history. Methods: The medical records of 6 807 patients diagnosed with BPPV from the Vertigo Database of Vertigo Clinical Diagnosis, Treatment, and Research Center of Beijing Tiantan Hospital, Capital Medical University, between January 2019 and October 2021 were retrospectively analyzed. The data included basic demographic information, clinical symptoms in a structured medical history questionnaire, and the time interval from the appearance of BPPV symptoms to diagnosis consultation. The patients were divided into the young and middle-aged group (<65 years old) and the older group (≥65 years old). The differences in clinical symptoms and consultation time were compared between these two groups. Categorical variables were represented by numbers (%), and compared using Chi-squared tests or Fisher's exact probability test for analysis; whereas, continuous variables conforming to normal distribution were represented by mean±standard deviation. Both data groups were compared and analyzed by Student's t-test. Results: The mean age of the older group was 65-92 (71±5) years, while the mean age of the middle-aged group was 18-64 (49±12) years. The incidence of vertigo (42.5% vs. 49.1%, χ2=23.69, P<0.001); vertigo triggered by changes in position of the head or body (52.4% vs. 58.7%, χ2=22.31, P<0.001); and autonomic symptoms (10.1% vs. 12.4%, χ2=7.09, P=0.008) were lower, but hearing loss (11.8% vs. 7.8%, χ2=27.36, P<0.001) and sleep disorders (18.5% vs. 15.2%, χ2=11.13, P=0.001) were higher in the older group than in the young and middle-aged group. The time from the appearance of dizziness to diagnosis was commonly longer in the older patient group than the other group (55.0% vs. 38.5%, χ2=55.95, P<0.001). Conclusions: Older patients with BPPV have more atypical symptoms and complex concomitant symptoms than young and middle-aged patients. For older patients with dizziness, positional testing is needed to confirm the possibility of BPPV even if the clinical symptoms are atypical.

Abstract
OBJECTIVE To investigate the status of depression and social anxiety in children and adolescents, and to analyze the association between body fat distribution and depression, social anxiety in children and adolescents. METHODS A total of 1 412 children aged 7 to 18 years in Beijing were included by stratified cluster random sampling method. Body fat distribution, including total body fat percentage (total BF%), Android BF%, Gynoid BF% and Android-to-Gynoid fat ratio (AOI), were obtained by dual-energy X-ray absorption method. Depression and social anxiety were evaluated by Children Depression Inventory and Social Anxiety Scale for Children. Multivariate linear regression and restricted cubic spline analysis were used to estimate the linear and non-linear correlation between body fat distribution and depression and social anxiety. RESULTS 13.1% and 31.1% of the children and adolescents had depressive symptoms and social anxiety symptoms respectively, and the detection rate of depression and social anxiety in the boys and young groups was significantly lower than those in the girls and old groups. There was no significant linear correlation between total BF%, Android BF%, Gynoid BF%, AOI and depression and social anxiety in the children and adolescents. However, total BF% and Gynoid BF% had significant nonlinear correlation with depression, showing an inverted U-shaped curve relationship with the tangent points of 26.8% and 30.9%, respectively. In terms of the nonlinear association of total BF%, Android BF%, Gynoid BF% and AOI with depression and social anxiety, the change trends of the boys and girls, low age group and high age group were consistent. The overall anxiety risk HR of body fat distribution in the boys was significantly higher than that in the girls, and the risk HR of depression and social anxiety were significantly higher in the high age group than those in the low age group. CONCLUSION There was no significant linear correlation between body fat distribution and depression and social anxiety in children and adolescents. Total BF% and depression showed an inverted U-shaped curve, mainly manifested in Gynoid BF%, and this trend was consistent in different genders and different age groups. Maintaining children and adolescents' body fat distribution at an appropriate level is the future direction of the prevention and control of depression and social anxiety in children and adolescents.

Abstract
Objective: To analyze and predict the epidemic trend of overweight and obesity among children and adolescents aged 7-18 years in China from 1985 to 2019. Methods: Data were collected from the Chinese National Survey on Students Constitution and Health in 1985, 1995, 2000, 2005, 2010, 2014, and 2019 with the sample size of 409 945, 204 931, 209 209, 234 420, 215 317, 214 353, and 212 711, respectively. Overweight and obesity were evaluated according to the "classification standard of the weight index value of overweight and obesity screening for Chinese school-age children and adolescents" of the Working Group on Obesity in China (WGOC). The detection rate and average annual growth rate of overweight and obesity, and single obesity among children and adolescents aged 7-18 years were calculated, and ArcGis10.6 software was used to analyze the difference in the prevalence of overweight and obesity among children and adolescents in different regions in 2019. Polynomial regression function was used to fit the prevalence and average annual growth rate of overweight and obesity, and single obesity among children and adolescents from 1985 to 2019, and to predict the prevalence of overweight and obesity and single obesity among children and adolescents in China. Results: In 2019, the total prevalence of overweight and obesity among children and adolescents aged 7-18 years in China was 23.4%, and the prevalence of single obesity was 9.6%. The prevalence of overweight and obesity among urban children and adolescents was higher than that in rural areas (25.4% vs. 21.5%), and the prevalence in boys was higher than that in girls (28.4% vs. 18.4%) (both P values<0.001). In 2019, there was a large regional disparity in the prevalence of overweight and obesity in different provinces, with the lowest in Guangdong (12.2%) and the highest in Shandong (38.9%), and the high epidemic areas were mainly concentrated in North China and Northeast China. From 1985 to 2019, the prevalence of overweight and obesity among children and adolescents aged 7-18 years in China increased from 1.2% to 23.4%, with an increase of 18.1 times, while the prevalence of obesity alone increased from 0.1% to 9.6%, with an increase of 75.6 times. The prevalence of overweight and obesity in urban boys, urban girls, rural boys and rural girls increased from 1.3%, 1.5%, 0.5%, and 1.6% in 1985 to 31.2%, 19.4%, 25.6%, and 17.4% in 2019, with an increase of 22.3, 11.7, 54.2, and 10.1 times, respectively. According to the prediction model, the prevalence of overweight and obesity among children and adolescents aged 7-18 years in China will increase from 23.4% in 2019 to 32.7% in 2030, and the prevalence of obesity alone will increase from 9.6% in 2019 to 15.1% in 2030. The growth of rural children and adolescents is obvious. By 2025, the prevalence of overweight and obesity among rural children and adolescents in China will comprehensively exceed that of urban, and there will be an "urban-rural reversal" phenomenon. At the same time, the prevalence of children's obesity in China's low, medium and high epidemic areas will also continue to increase. By 2035, the prevalence of overweight and obesity among children and adolescents in medium epidemic areas will exceed that in high epidemic areas, and there will be a "provincial reversal" phenomenon. Conclusion: From 1985 to 2019, the overweight and obesity of children and adolescents in China will continue to grow rapidly with large regional differences.

Abstract
Objective: To explore the epidemiological characteristics and geographical distribution of unhealthy lifestyle among children and adolescents of Han nationality in China and obtain evidence for proposing the related strategies to improve the well-being of this population. Methods: Students aged 6-22 years old were selected from the Chinese National Survey on Students Constitution and Health in 2019. The prevalence of unhealthy lifestyles (physical inactivity, lack of outdoor activity, sedentary behavior, excessive screen time, sleep insufficiency, unhealthy eating behavior) between sex, residence, and age groups was calculated and compared. Multilevel logistic regression was used to explore the influencing factors of unhealthy lifestyle. Results: The prevalence of moderate-to-vigorous physical activity less than 1 h/d or 30 min/d were 82.06% and 54.69%, respectively. The prevalence of less than 2 h/d or 3 h/d of outdoor activities were 95.20% and 83.26%, respectively. The prevalence of more than 2 h/d or 3 h/d of sitting time were 50.64% and 31.92%, respectively. The prevalence of more than 2 h/d or 3 h/d of screen time were 42.02% and 27.79%, respectively. The prevalence of sleep insufficiency, excessive sugary beverages consumption (≥ 1 time/d), and insufficient consumption of eggs, milk, and breakfast (<7 d/week) were 66.49%, 20.97%, 83.36%, 70.71%, and 34.34%, respectively. The prevalence of severe sleep insufficiency, excessive sugary beverages consumption (≥ 3 times/d), and insufficient consumption of eggs, milk, and breakfast (≤2 d/week) were 27.77%, 8.21%, 47.21%, 32.36% and 9.73%, respectively. Conclusion: In 2019, unhealthy lifestyle is common among Han students aged 6-22 years in China. It is of importance to propose policies to strengthen the health education and initiatives to support healthy behaviors in Han children and adolescents. Jointly promotion on the creation of a healthy environment for Han children and adolescents, and formulation of targeted improvement measures in accordance with the epidemic characteristics in various regions are essential to improve the healthy lifestyle of this population.

Abstract
Although gastric cancer with para-aortic lymph node (PAN) metastasis is commonly regarded as unresectable, surgeons have explored the optimal treatment for patients with PAN metastases limited to No.16a2/b1 in the past few decades. Preoperative systemic therapy combined with D2 gastrectomy plus PAN dissection may improve the prognosis of these patients. In this multicenter phase II trial, 29 gastric cancer patients with PAN metastasis limited to No.16a2/b1 will receive preoperative treatment with nab-paclitaxel, oxaliplatin, S-1 (nab-POS: nab-paclitaxel, oxaliplatin, S-1) and sintilimab followed by D2 gastrectomy plus PAN dissection; and postoperative treatment with oral S-1, intravenous sintilimab and intraperitoneal paclitaxel. The end points for the study are 3-year overall survival, 3-year disease-free survival, pathological response rate, incidence of postoperative complications and adverse events.

Abstract
Butyrate, normally produced by probiotics in the gut, not only provides energy for cells, but also changes the phosphorylation, acetylation and methylation levels of many proteins in cells. As a result, it affects the expression of many genes and the transmission of cell signals. Through G protein-coupled receptors, butyrate promotes the secretion of intestinal mucus and the formation of epithelial barriers, and attenuates the impacts of the pathogenic bacteria and their metabolites on human body. The Toll-like receptors (TLRs) are a group of pattern recognition receptors, and their activation causes the translocation of nuclear factor κB (NF-κB) from the cytoplasm to the nucleus and eventually leads to expression and secretion of various pro-inflammatory factors and chemokines. The expression of TLRs is also involved in the pathogenesis of some inflammatory diseases and tumors. The purpose of this review is to summarize the effects of butyrate on TLRs and their downstream signaling pathways. We not only summarized the production of butyrate, the expression of TLRs and the influence of their interaction on the body under the conditions of inflammation and tumor, but also discussed the potential role of butyrate as a bacterial metabolite in the treatments of some human diseases.

Abstract
OBJECTIVE To explore and analyze the relationship between early onset of puberty and different types of obesity in children, by combining large sample cross-sectional survey data with long-term longitudinal cohort data, so as to provide clues for further clarifying the health hazards of early onset of puberty and obesity prevention and control. METHODS The research data were from the cross-sectional survey data of seven provinces(autonomous regions, municipalities) in China and the cohort data of adolescent development in Xiamen. The study first found the association between early onset of puberty and obesity by Logistic regression on the cross-sectional data, and then used Poisson regression to analyze the association between early puberty initiation and various types of obesity risk. RESULTS In the study, 43 137 and 1 266 children were included in the cross-sectional survey and cohort survey respectively. The cross-sectional study found that among the girls aged 10-13 years, compared with the girls of the same age who did not start puberty, the body mass index (BMI)-Z score of the girls in the puberty start group was 0.5-0.8 higher, and the waist circumference Z score was 0.4-0.7 higher, and the risk of various types of obesity was higher. At the same time, the early onset of puberty was positively correlated with simple obesity, central obesity and compound obesity, the OR (95%CI) were 1.86 (1.42-2.44), 1.95 (1.65-2.32) and 1.86 (1.41-2.45), respectively. No significant association was found in boys. According to the cohort data, in girls, the risk of simple obesity was 6.00 times [RR (95%CI): 6.00 (1.07-33.60)], the risk of central obesity was 3.30 times [RR (95%CI): 3.30 (1.22-8.92)], and the risk of compound obesity was 5.76 times [RR (95%CI): 5.76 (1.03-32.30)], compared with the group without early puberty initiation, while no association between early puberty initiation and obesity was found in boys. CONCLUSION Based on the cross-sectional survey and longitudinal cohort survey, it is confirmed that the early onset of puberty in girls may increase the risk of simple obesity, central obesity and compound obesity, while there is no significant correlation between puberty onset and obesity in boys.

Abstract
This study focuses on the function of WTAP in esophageal squamous cell carcinoma (ESCC) samples and cell lines. The results showed that WTAP expression in ESCC tissues was significantly upregulated in 78.1% (57 of 73) of the ESCC tissues at the protein level compared with adjacent non-cancerous tissues via immunohistochemical staining. The WTAP protein expression level was positively correlated with the lymph node metastasis and TNM stage, and patients with higher WTAP protein expression level exhibited a shorter overall survival interval. Knocking down WTAP significantly reduced cell proliferation and migration but promoted cell apoptosis of TE-1and KYSE150 cells. Moreover, WTAP inhibition reduced the expression of ki67 and Snail related to cell proliferation and migration but increased the expression of Bax and Caspase-3 which were involved in cell apoptosis. In conclusion, our results suggest that the WTAP, a potential biomarker of ESCC, maybe play an important role in ESCC-genesis through regulating expression of genes related to cell proliferation, migration and apoptosis.

Abstract
Objective: We aimed to assess the effects of outdoor time in preventing incident myopia among primary school students and evaluate its differences among different grades to provide evidence for policy formulation related to myopia prevention. Methods: This study is a cohort study. We investigated 6 046 grade 1 to 5 students in 9 provinces, Jiangsu, Shanghai, Fujian, Shanxi, Henan, Hunan, Gansu, Chongqing, and Guangxi. In 2019, we measured their myopia on site. In 2020, we did a follow-up visit on those students to detect the myopia incidence rate. Information regarding outdoor time and myopia-related behaviors were obtained from a questionnaire within one week of visual acuity measurement in 2020. The chi-square test and Cochran-Armitage trend test compared the differences between groups. The Cox proportional hazards risk model was used to test the relationship between outdoor time and myopia. Results: In 2020, the overall myopia incidence rate of grade 1 to 5 students in the baseline was 27.5%; while 23.0% in grades 1 and 2 students and 31.7% in grades 3 to 5 students, respectively. After controlling for covariates, for students in grade 1 to 2, those with ≥1 hour of outdoor time per day were at 0.76 (95%CI: 0.62-0.93, P=0.008) times risk of being myopia than that of students with <1 hour of outdoor time per day; while for students in grades 3 to 5, an average of ≥3 hours of outdoor time per day was required to have a significant protective effect on myopia. The students with ≥3 hours of outdoor time per day were less likely to be myopia (OR=0.75, 95%CI: 0.61-0.93, P=0.007) than those students with <3 hours of outdoor time per day. Conclusions: For grade 1 and 2 students, 1 hour of outdoor time per day could reduce the incidence of myopia, whereas for grade 3 to 5 students, 3 hours of outdoor time per day could effectively reduce the incidence of myopia. Therefore, the recommendations for outdoor time as myopia prevention should be different for different grades. The higher the grade is, the more outdoor time should be spent to reduce myopia incidence. Moreover, other factors that affect myopia's incidence should be also paid attention to, and a comprehensive approach should be adopted to prevent and control the incidence of myopia.

Abstract
Although recent advances in systemic chemotherapy have improved the clinical outcomes of gastric cancer patients with peritoneal metastasis, the peritoneum still represents a common site of treatment failure and disease recurrence. Neoadjuvant intraperitoneal-systemic chemotherapy has been acknowledged as a more aggressive treatment for gastric cancer patients with peritoneal metastasis. In this multicenter phase III randomized controlled trial, 238 patients will be randomly separated into two groups in a 2:1 ratio after laparoscopic exploration. The experimental arm will receive the proposed neoadjuvant intraperitoneal-systemic chemotherapy regimen, whereas the control group will receive a Paclitaxel + S-1 (PS) chemotherapy regimen. The endpoints for the study are overall survival, response rate, gastrectomy radicality rate, progression-free survival and adverse events.

Abstract
Objective: To investigate the seasonal changes of benign paroxysmal positional vertigo (BPPV) onset, and explore the relationship between vascular risk factors and the seasonal patterns of BPPV. Methods: Data of 3 886 patients subjected to vestibular function examination and diagnosed with BPPV who underwent manipulation or instrumental repositioning from January 1, 2016 to December 31, 2019 in the Department of Neurology, Beijing Tiantan Hospital were retrospectively analyzed. Demographic information and medical history of the patients were recorded. Weather temperature data of Beijing were obtained and monthly averages were calculated. The relationship between the BPPV onset and temperature and seasonality was investigated. Meanwhile, the influence of vascular risk factors on the seasonal patterns of BPPV was determined. Results: BPPV is more common in women (n=2 667). The male to female ratio of patients was approximately 1∶2, with a mean age of (55±13) years. The cases of BPPV in spring (March-May), summer (June-August), autumn (September-November) and winter (December-February) were 1 000 (25.7%), 911 (23.4%), 808 (20.8%) and 1 167 (30.0%), respectively. The peak incidence of BPPV occurred in December (n=491) and the lowest occurred in September (n=251). The number of BPPV cases diagnosed monthly was inversely correlated with mean temperature (R2=0.317; P<0.001). Patients with ≥2 vascular risk factors were at higher risk of developing BPPV in spring or winter than those without risk factors (OR=1.32, 95%CI: 1.13-1.53,P<0.001). Proportion of onset in spring or winter increased with each additional risk factor (P trend<0.001). Conclusions: BPPV often occurs in the months with low temperature (spring and winter) and the number of cases is inversely correlated with temperature. Compared with those with no vascular risk factors, patients with more vascular risk factors are more likely to develop BPPV in spring and winter.

Abstract
Although complete omentectomy is traditionally performed in patients with gastric cancer as part of radical gastrectomy to ensure the elimination of micrometastases, the prognostic value of omentectomy during gastrectomy remains unclear. Retrospective studies have shown that the incidence of metastases in the greater omentum is very low in T1-T3 gastric cancer. Thus radical gastrectomy with D2 lymphadenectomy and preservation of the greater omentum may be a proper curative treatment for gastric cancer patients with T1-T3 tumors. The aim of this article is to describe the design and rationale for this prospective, randomized controlled DRAGON-05 trial, conducted to evaluate the prognostic value of omentum-preserving gastrectomy for patients with T1-T3 gastric cancer. Clinical trial registration: ChiCTR2000040045 (ClinicalTrials.gov).

Abstract
In the 2020 Final Rule, the Center for Medicare & Medicaid Services adopted a new coding structure and accepted the substantial increase in valuation for office/outpatient Evaluation and Management codes set to begin in 2021. Given budget neutrality requirements, the projected increase in reimbursement will require a reduction in the conversion factor to offset such increases. The aim is to inform neuroradiologists the impact of these proposed changes on reimbursement and the profession.

Abstract
Hepatocellular carcinoma (HCC) is the third deadliest cancer in the world with high morbidity and poor prognosis. CTCFL (CCCTC-binding factor like) is a member of the cancer testis antigen (CTA) family with oncogenic properties. To demonstrate whether the hypomethylation of CTCFL promoters in plasma could be used as a noninvasive biomarker to predict poor prognosis of HCC, we extracted cell-free DNA from the plasma and detected the methylation status of CTCFL in 43 HCC, 5 liver cirrhosis and 6 benign lesion samples using methylation specific PCR (MSP). Our study indicated that the hypomethylation of CTCFL promoters in HCC plasma samples (60.4%) was significantly different from that in benign lesion plasma samples (16.7%) with a p-value of 0.043. Analysis of clinicopathological data showed that the methylation status of CTCFL promoters was significantly correlated with microvascular involvement (MVI) (p=0.001) and postoperative recurrence (p=0.031). Furthermore, clinical prognosis data of 347 HCC patients from The Cancer Genome Atlas (TCGA) database displayed that the hypomethylated group had worse overall survival than the hypermethylated group (p=0.0056). In conclusion, we provide evidence that the hypomethylation of CTCFL promoters in cell-free DNA is a biomarker for monitoring HCC patients, which can be used as a noninvasive prediction index for tumor recurrence and provide the individualized decision-making for clinicians.

Abstract
The use of transoral sonography-guided fine-needle aspiration for intraoperative localization of retropharyngeal masses has been described by Fornage et al. The purpose of this study was to assess the accuracy of this technique. We reviewed the images and medical records of 26 patients with a retropharyngeal lesion suspicious for a metastatic lymph node of Rouviere identified on CT and/or PET/CT. There were 14 patients with a history of thyroid cancer, 7 with mucosal squamous cell carcinoma, 1 with renal cell carcinoma, 1 with parotid acinic cell cancer, 1 with metastatic colon adenocarcinoma, and 2 with no history of cancer. Intraoperative transoral sonography was performed using a commercially available endovaginal transducer. A transoral sonography-guided fine-needle aspiration was performed with a 25-cm-long 20-ga Chiba needle through a needle guide attached to the transducer shaft. Cytopathologic results were categorized as malignant, benign, or nondiagnostic. Transoral sonography and transoral sonography-guided fine-needle aspiration were performed in all patients. A diagnostic specimen was obtained in 25 of 26 (96%) patients with a 100% overall accuracy. Twelve patients underwent subsequent transoral resection of the retropharyngeal mass. In each patient, surgical pathology confirmed the fine-needle aspiration biopsy result. In 4 patients, transoral sonography-guided injection of methylene blue was used to facilitate intraoperative localization of the metastatic retropharyngeal mass. Transoral sonography and transoral sonography-guided fine-needle aspiration of suspicious masses in the retropharyngeal space are highly accurate procedures for identification and cytologic evaluation of benign and metastatic lymph nodes of Rouviere and for presurgical localization.

Abstract
Objective: To investigate the differences of clinicopathological features, diagnosis, treatment and prognosis between patients with extra-gastrointestinal stromal tumors (EGIST) and duodenal gastrointestinal stromal tumors (DGIST). Methods: A retrospective case - control study was performed. Case inclusion criteria: (1) tumor confirmed by histology and pathology; (2) primary tumor locating in the extra - gastrointestinal tract or duodenum; (3) without other synchronous tumors; (4) complete clinical and pathological data. Clinical data of 20 EGIST patients and 32 DGIST patients from March 2011 to September 2016 at Department of Gastrointestinal Surgery, Ruijin Hospital, Shanghai Jiaotong University School of Medicine were retrospectively collected and analyzed. The observational parameters included clinicopathological characteristics, treatment and prognosis conditions. Continuous data of abnormal distribution were expressed as median (range) and compared using the Mann-Whitney U-test. Survival curves were drawn by the Kaplan-Meier method and compared with the Log-rank test. Results: Of the 20 EGIST patients, 8 were males and 12 were females with age of 61.0 (30.0 to 86.0) years and of the 32 DGIST patients, 12 were males and 20 were females with age of 55.5 (27.0 to 70.0) years. Compared with DGIST patients, EGIST patients were older (U=188.000, P=0.012], had larger tumor size [10.0 (3.0 to 29.0) cm vs. 4.0 (1.5 to 10.0) cm, U=98.500, P<0.001] and higher ratio of high risk classification [85.0% (17/20) vs. 12.5% (4/32), χ(2)=26.870, P<0.001]. Among the 20 EGIST patients, 5 were diagnosed with distal metastasis and received imatinib (400 mg/d), and the other 15 patients underwent radical resection who were included in survival analysis. All the 32 DGIST patients underwent radical resection. The median follow-up of whole group was 43 (14 to 76) months. The 3-year recurrence/metastasis-free survival rate of 15 cases undergoing radical resection in the EGIST group was 85.6%, which was lower than that of the DGIST group (88.6%), and the difference was not statistically significant (P=0.745). There was no significant difference in the 3-year overall survival rate between the EGIST group (92.9%) and the DGIST group (100%) (P=0.271). Conclusions: As compared to DGIST, EGIST mostly occurs in those with older age, larger tumor size and higher risk grade. The prognosis of EGIST patients after radical resection is similar to that of DGIST patients.

Abstract
Professional use of social media continues to increase. We analyzed Twitter use of our own American Society of Neuroradiology (ASNR) 2018 annual meeting, reviewing all Twitter posts (3020 tweets from 523 participants) containing the hashtag #ASNR18 from May 21, 2018, to June 12, 2018, extracting the transcripts from Symplur. Then, each tweet was categorized by the role of user, type of tweet, and topic. The dominant user category was neuroradiologist/radiologist (63%). The keynote address, "The Radiology Renaissance: Shaping the Future of Healthcare," presented by Andy DeLao @Cancergeek was the most frequently tweeted topic (10%). Comment on a session was the major type of tweet. When we compared the data with a similar analysis in 2014, our data analysis showed a growth in the use of Twitter in only 4 years.

Abstract
Objective: To investigate the distribution and resistance of pathogens isolated from blood cultures in patients with hematological malignancies after chemotherapy in Union Hospital of Fujian Medical University so as to understand the real situation of blood stream infection (BSI) and provide the basis for rational use of antibiotics in clinic. Methods: The data of 657 strains isolated from blood culture specimens of patients with hematological malignancies from January 2013 to December 2016 were collected analyzed. Results: A total of 657 cases of blood culture positive bacterial strains were included in the study, involving 410 cases (62.4%) with single Gram-negative bacteria (G(-) bacteria) , 163 cases (24.8%) with single Gram-positive bacteria (G(+) bacteria) , 50 cases (7.6%) with single fungi. The most common 5 isolates in blood culture were Klebsiella pneumoniae (17.5%) , Escherichia coli (17.2%) , Coagulase negative staphylococci (CNS) (14.9%) , Pseudomonas aeruginosa (14.2%) and Staphylococcus aureus (3.5%) . The extended-spectrum beta-lactamase (ESBL) production rates of Klebsiella pneumoniae and Escherichia coli were 25.2% and 55.8%, respectively. ESBL producing strains were almost more resistant than non-ESBL producing strains. The resistance rates of Enterobacteriaceae to carbapenems, piperacillin/tazobactam and tigecycline were lower than 14.0%. The resistance rates of Pseudomonas aeruginosa to a variety of drugs were lower than 12.0%. Tigecycline-resistant Acinetobacter baumannii bacteria were not detected, and the resistance rates of Acinetobacter baumannii to cefixime and cefotaxime were 7.1%. Methicillin-resistant strains in CNS (MRCNS) and in Staphylococcus aureus (MRSA) accounted for 84.7% and 43.5%, respectively. Vancomycin, linezolid and tigecycline-resistant G(+) bacteria were not detected. Conclusion: The pathogens isolated from blood culture were widely distributed. Most of them were G(-) bacteria, and the resistance to antibiotics was quite common. Furhermore, vancomycin, linezolid and tigecycline can be chosen empirically to treat patiens who ar suspected to have G(+) bacterial BSI.

Abstract
Diseases caused by Aeromonas veronii in freshwater fish have been widely reported, but other species such as aquatic mammals have probably been overlooked. Here, we identified one isolate of A. veronii from a Yangtze finless porpoise Neophocaena asiaeorientalis asiaeorientalis exhibiting disease and mortality, and subsequently confirmed its virulence in artificial infection of BALB/c mice. The bacterial isolate was identified as A. veronii based on physiological, biochemical, and phenotypic features, and homology of the 16S rRNA, cpn60, rpoB, dnaJ and gyrB genes. Our results expand the known host spectrum of A. veronii, which is of great importance for the etiology of porpoise, dolphin, and other cetacean diseases.

Abstract
Toll-like receptors (TLRs) can be recognized and activated by different pathogen associated molecular patterns (PAMPs), which induce innate immune response and inflammation of the body. Na+/H+ exchangers (NHEs) not only play roles in the regulation of cellular pH and cell volume, maintenance of the cavity microenvironment and nutrients absorption, but also are related to cell proliferation, migration and apoptosis. The activity and membrane protein expression of NHEs are inhibited under the inflammation condition. It has been shown that the activation of TLR2 in colon epithelial cells can inhibit the activity of NHE1 through MyD88 independent pathway, which involves the recruitment of Src and the phosphorylation of PI3Ks. Other studies on intestinal macrophage showed long-term LPS stimulation can induce TLR4 activation through MyD88-dependent pathway (TLR4/MyD88/NF-κB) and induce inflammation and degeneration of intracellular NHE1, which leads to NHE1 activity inhibition. But short-term LPS exposure increases the activity and protein expression of NHE1. The activation of TLR5 increases the activity of NHE3. The activity and/or expression of NHE3 in intestinal macrophages in colitis patients and model animals were decreased. In renal tubular epithelial cells, basolateral LPS stimulation inhibits luminal NHE3 activation through TLR4/MyD88-dependent MAPK/ERK signaling pathway. And LPS stimulation on the lumen side activates TLR4/MyD88-dependent PI3K-AKT-mTOR signaling pathway, which results in the inhibition of NHE1 activity in basolateral side, and then affects the NHE3 function of the lumen side.

Abstract
Clear cell renal cell carcinoma (ccRCC) is the most common subtype of renal cell carcinoma. The chromo-helicase-DNA binding proteins (CHDs), containing nine members named CHD1-9, act as regulators of the chromatin remodeling process and gene expression. To determine the correlation between CHD9 expression and ccRCC, we performed an immunohistochemical staining in a tissue microarray (TMAs) containing tissue samples from 88 ccRCC patients. The results showed that cytoplasm CHD9 expression was statistically decreased in tumor tissues compared to adjacent tissues (8.54±2.90 vs 12.61±2.05, P=0.000), while nuclear CHD9 expression was upregulated in the tumor tissues (1.47±2.93 vs 0.29±1.24, P=0.000). A univariate analysis found that cytoplasm CHD9 expression in cancer tissues was correlated with the patients' pathological grading (P=0.002, r=0.330), the clinical stages (P=0.02, r=0.250) and the T grading (P=0.024, r=0.241) significantly. In addition, cytoplasm CHD9 expression in non-tumor tissues was correlated with the ccRCC patients' pathological grading (P=0.031, r=-0.231) significantly. Patients with high cytoplasm CHD9 expression had a significantly worse prognosis than those with low cytoplasm CHD9 expression levels (59.7% vs 85.7%, P=0. 042). In conclusion, our study indicated the important role of CHD9 in ccRCC and suggested CHD9 may be a potential biomarker for prognostic prediction and a new target for therapy.

Abstract
The aim of this study was to elaborate the correlation between metastasis-associated protein (MTA) family and the occurrence, progression, prognosis and chemotherapy efficiency in nasopharyngeal carcinoma (NPC).The expression of MTA1, MTA2 and MTA3 protein were detected by immunohistochemistry in a tissue microarray (TMAs) which contains tissue samples of 152 NPC patients embedded by formalin-fixed paraffin. The MTA proteins were mainly expressed in the nuclei of NPC tissues and the correlations between MTAs expression and clinical parameters as well as prognosis of NPC patients showed ethnical differences according to statistically analysis. The results showed that in Han ethnic group, MTA1 expression was positively correlated with N staging, while the expression of MTA2 was negatively correlated with age, and the expression of MTA3 was positively correlated with gender. Patients with high MTA1 expression had poorprognosis. In Zhuang ethnic group, only MTA3 expression was positively correlated with age, recurrence and metastasis of NPC patients; neither MTA1 nor MTA2 expression had any correlation with clinical indexes. Patients with high MTA3 expression had unfavorable prognosis. In addition, our results showed that overall survival among Zhuang NPC patients with low expression of MTA2 increased significantly owing to "carboplatin + fluorouracil" chemotherapy. This therapeutic success, however, did not translate to longer overall survival among Han NPC patients. The biological function of MTA protein family in NPC patients was different among different ethnic groups. In conclusion, we demonstrated that MTAs had a certain tumor promoting function in patients with NPC, and the biological functions of MTAs might be ethnic differences, which suggesting MTAs to be important markers for guiding clinical treatment of NPC.

Abstract
Objective: To understand the epidemiological characteristics and viral sources of dengue fever outbreak in Guangxi Zhuang Autonomous Region (Guangxi) in 2014. Methods: A combined analysis of epidemiological characteristics and genetic characteristics were performed in this study. The time, population and area distributions of the cases were analyzed. Serum samples were collected from dengue fever cases to detect NS1 antigen by using commercial ELISA kits according to the guideline of the manufacture. RT-PCR assay was conducted to detect dengue virus in NS1 positive samples. Phylogenetic tree based on E gene sequence of dengue virus were further analyzed. Results: During September-December 2014, an outbreak of dengue fever caused by dengue virus type 1 and 2 occurred in Guangxi, a total of 854 cases were reported without death, including 712 laboratory confirmed cases and 142 clinical diagnosed cases, in which 79.63% (680/854) occurred during 22 September-21 October 2014. All the cases had typical dengue fever symptoms. Most cases occurred in Nanning and Wuzhou, in which 83.61% (714/854) were in age group 15-59 years; 46.60% (398/854) were staff or people engaged in commercial service. A total 526 serum samples were tested for dengue virus serotype by RT-PCR assay. Among 414 positive samples, 345 were positive for dengue virus type 1 (DENV-1) and 69 were positive for dengue virus type 2 (DENV-2), no DENV-3 and DENV-4 were detected. The results of phylogenetic analysis of E gene sequence indicated that the sequences of 99.12%(113/114) of DENV-1 strains in Nanning in China shared 100.00% homology with the isolate (SG EHI D1/529Y13) from Singapore in 2013, which belonged to the genotype Ⅰ; All the DENV-2 isolates from Wuzhou shared 99.80% homology with the isolate (D14005) from Guangdong province, which belonged to genotype Cosmopolitan. Conclusions: The outbreak was caused by DENV-1 from Singapore and DENV-2 from Guangdong province in China. It is necessary to strengthen the surveillance and early warning for imported dengue fever, conduct vector control and improve the diagnosis of suspected dengue fever cases for the effective control of dengue fever outbreak.

Abstract
In this study, cultures of neural stem-progenitor cells (NSPC) from the brain of green terror cichlid Aequidens rivulatus were established and various NSPCs were demonstrated using immunocytochemistry. All of the NSPCs expressed brain lipid-binding protein, dopamine- and cAMP-regulated neuronal phosphoprotein 32 (DARPP-32), oligodendrocyte transcription factor 2, paired box 6 and sex determining region Y-box 2. The intensity and localisation of these proteins, however, varied among the different NSPCs. Despite being intermediate cells, NSPCs can be divided into radial glial cells, oligodendrocyte progenitor cells (OPC) and neuroblasts by expressing the astrocyte marker glial fibrillary acidic protein (GFAP), OPC marker A2B5 and neuronal markers, including acetyl-tubulin, βIII-tubulin, microtubule-associated protein 2 and neurofilament protein. Nevertheless, astrocytes were polymorphic and were the most dominant cells in the NSPC cultures. By using Matrigel, radial glia exhibiting a long GFAP+ or DARPP-32+ fibre and neurons exhibiting a significant acetyl-tubulin+ process were obtained. The results confirmed that NSPCs obtained from A. rivulatus brains can proliferate and differentiate into neurons in vitro. Clonal culture can be useful for further studying the distinct NSPCs.

Abstract
Marbled eels, Anguilla marmorata (Quoy & Gaimard), cultured in Taiwan exhibited haemorrhage and mortality in January 2012. The severely diseased eels bled from the gills and showed congestion of the central venous sinus of the gill filaments and haemorrhage throughout the body similar to viral endothelial cell necrosis of eel. In this study, a novel polyomavirus (AmPyV) was isolated from the diseased eels using the AMPF cell line established from the pectoral fin of healthy marbled eels. AmPyV was found to encode a long T-antigen orthologous gene. Phylogenetic analysis showed that AmPyV was closely related to Japanese eel endothelial cell-infecting virus. PCR assays revealed AmPyV infection throughout the systemic organs. AmPyV proliferated in the AMPF, EK-1 and EO-2 cells at temperatures 25-30 °C, and the progeny virus yields were 10(7.0) , 10(7.4) and 10(7.7) TCID50 mL(-1) , respectively. The purified virions were icosahedral particles, 70-80 nm in diameter. No clinical signs or mortality was observed among the eels injected with the virus; however, the virus was reisolated from the brain, eyes, kidneys, fins and gills of infected eels 2 month after injection. Our results suggest that AmPyV exhibits a latent infection. Pathogen of the disease needs to study further.

Abstract
OBJECTIVE To explore the the expression of Klotho mRNA and protein in placenta of macrosomia and its relationship with the birth weight of neonates. METHODS The cases were from November 2014 to March 2015 in Shengjing Hospital of China Medical University, divided into 4 groups: the gestational diabetes with macrosomia group (GM), the gestational diabetes with normal birth weight group (GN), the normal pregnancy with macrosomia group (NM) and the normal pregnancy with normal birth weight group (NN). Klotho mRNA and protein expression in the placenta were detected by immunohistochemistry SP method, real-time fluorescent quantitative PCR and western blot, respectively, and were compared among the 4 groups. RESULTS (1) Immunohistochemical detection showed the positive rate of Klotho protein was significantly higher in the placenta of GM (93%,28/30) than in the GN (73%,22/30; P<0.05). The positive rate was significantly higher in the placenta of NM (97%,29/30) than in the NN (80%,24/30; P<0.05). (2) Real-time fluorescent quantitative PCR showed the Klotho mRNA expression was significantly higher in the placenta of GM (4.3 ± 3.1) than in the GN (2.1 ± 2.4; P<0.05). The Klotho mRNA expression was also significantly higher in the placenta of NM (4.8± 3.4) than in the NN (2.6± 3.3; P<0.05). (3) Western blot showed the Klotho protein expression was significantly higher in the placenta of GM (1.27±0.90) than in the GN (0.64±0.24; P<0.05). It was also significantly higher in the placenta of NM (2.51±3.52) than in the NN (0.77±0.37; P<0.05). (4) There were no significant differences in the expression of Klotho mRNA and protein between GM and NM, GN and NN (P>0.05). CONCLUSIONS The up-regulation of Klotho gene may be associated with macrosomia. The relationship is not affected by the complication of gestational diabetes.

Abstract
This study aimed to investigate the therapeutic mechanism of treating SMMC-7721 liver
cancer cells with magnetic fluid hyperthermia (MFH) using Fe2O3
nanoparticles. Hepatocarcinoma SMMC-7721 cells cultured in vitro
were treated with ferrofluid containing Fe2O3 nanoparticles and
irradiated with an alternating radio frequency magnetic field. The influence of the
treatment on the cells was examined by inverted microscopy, MTT and flow cytometry.
To study the therapeutic mechanism of the Fe2O3 MFH, Hsp70,
Bax, Bcl-2 and p53 were detected by immunocytochemistry and reverse transcription
polymerase chain reaction (RT-PCR). It was shown that Fe2O3 MFH
could cause cellular necrosis, induce cellular apoptosis, and significantly inhibit
cellular growth, all of which appeared to be dependent on the concentration of the
Fe2O3 nanoparticles. Immunocytochemistry results showed that
MFH could induce high expression of Hsp70 and Bax, decrease the expression of mutant
p53, and had little effect on Bcl-2. RT-PCR indicated that Hsp70 expression was high
in the early stage of MFH (<24 h) and became low or absent after 24 h of MFH
treatment. It can be concluded that Fe2O3 MFH significantly
inhibited the proliferation of in vitro cultured liver cancer cells
(SMMC-7721), induced cell apoptosis and arrested the cell cycle at the
G2/M phase. Fe2O3 MFH can induce high Hsp70
expression at an early stage, enhance the expression of Bax, and decrease the
expression of mutant p53, which promotes the apoptosis of tumor cells.

Abstract
OBJECTIVE To study the disability identification for cases with clinical diagnosis of diffuse axonal injury (DAI) due to traffic accidents, and to explore the possible effects of DAI on identification results. METHODS Five hundred and fifty-six cases of cerebral injury due to traffic accidents were collected, including 467 cases diagnosed with cerebral contusion or laceration and 89 cases diagnosed with DAI. The identification results of different groups with diagnosis of DAI diagnosis, diagnosis of DAI with cerebral contusion (laceration), and diagnosis of cerebral contusion or laceration without DAI were compared and statistically analyzed, based on the results of CT and MRI re-review. RESULTS The disability identification levels in DAI group (20 cases), DAI group (69 cases) with cerebral contusion (laceration) and DAI group (467 cases) not complicated by cerebral contusion (laceration) were 7.72 +/- 1.09, 7.78 +/- 1.11, and 8.86 +/- 0.66, respectively. The disability levels of the two groups diagnosed with DAI were higher than those of the group without DAI diagnosis (P < 0.05). CONCLUSION Patients with DAI diagnosis might have more severe cerebral injury. In the identification process, one should pay attention to the possible missed diagnosis and misdiagnosis, and meanwhile avoid relying on those evidences provided only by CT and MRI.

Abstract
OBJECTIVES The aim of this study was to compare the effectiveness of IDF (International Diabetes Federation) and ATP-III (National Cholesterol Education Program-Adult Treatment Panel III) for predicting metabolic syndrome, and to evaluate the usefulness of these definitions for health promotion. DESIGN A cross-sectional study. SETTING A national random sample. PARTICIPANTS A population representative sample of 1021 54-91 year-old Taiwanese. MEASUREMENTS Subjects were measured for anthropometric and biochemical indicators and rated for the presence of metabolic syndrome using the two definitions. We evaluated the effectiveness of the two definitions in predicting MetS among those who had specific metabolic disorders. Results were analyzed with Student t-test and McNemar's test. RESULTS Among the 918 subjects who had one or more MetS-item disorders, ATP-III rated greater proportions of subjects as having MetS than IDF, but both definitions predicted less than 50% (37.7% and 45.4%, respectively) as having MetS. CONCLUSION Compared to IDF, ATP-III rated a greater proportion of subjects as having MetS, but both definitions missed more than 50% of subjects who had metabolic disorder(s). Since those who are missed have as much need for lifestyle intervention, the definitions appear not appropriate for health promotion.

Abstract
UNLABELLED Thermotolerant strains of lactic acid bacteria (LAB) were screened for their suitability for silage making at high temperatures. Four selected strains were identified by 16S rRNA sequencing analyses and added to unwilted and wilted Italian ryegrass for ensiling at 45°C. All four strains (HT1, HT2, HT3 and HT4) grew at 50°C and pH 4·0. Strains HT1 and HT2 were identified as Lactobacillus rhamnosus; HT3 and HT4 were identified as Lact. fermentum. Strains HT1 and HT2 were the most effective at improving the fermentation quality of Italian ryegrass silage, irrespective of wilting, as indicated by lower pH values, less NH(3) -N, and more lactic acid. In contrast, strains HT3, HT4 and a commercial inoculant consisting of Lact. plantarum and Pediococcus acidilactici conferred no or reduced benefits. Wilting alone did not improve the fermentation quality of Italian ryegrass at 45°C. Inoculating with thermotolerant Lact. rhamnosus HT1 and HT2 could improve the fermentation quality of silage at high temperatures. Lactobacillus rhamnosus HT1 and HT2 can be used as inoculants for silage making in the tropics and subtropics and could play an important role in developing silage production in such regions. SIGNIFICANCE AND IMPACT OF THE STUDY Grasses are often difficult to ensile in the tropics and subtropics because of the high temperatures there. To solve this problem, we screened for thermotolerant lactic acid bacteria and obtained two valuable strains of Lactobacillus rhamnosus, HT1 and HT2, which proved to be beneficial to silage fermentation at high temperatures. Lactobacillus rhamnosus HT1 and HT2 can be used as inoculants for silage making in the tropics and subtropics, and will play an important role in developing silage production in such regions.

Abstract
In animals, infection by the Epsilonproteobacteria Helicobacter spp. and H. cetorum is widespread. It has been suggested that H. cetorum may cause gastritis in cetaceans. The aim of our study was to investigate the presence of Helicobacter spp. in the fecal material of the endangered Yangtze finless porpoise Neophocaena phocaenoides asiaeorientalis. The fecal material of 12 porpoises living in the wild in Poyang Lake and 1 porpoise living in captivity at the Wuhan Baiji Dolphinarium were examined by PCR for the presence of Helicobacter spp. The fecal material of 8 of 12 wild porpoises and the captive porpoise were positive for Helicobacter spp. as determined by PCR using Helicobacter-specific primers, which target the 16S rRNA gene. A 16S rRNA clone library was then prepared from 1 sample isolated from a female porpoise living in the wild. DNA sequence analysis from 3 of the clones showed 98 to 99% identity to the H. cetorum 16S rRNA gene. These results demonstrate the prevalence of Helicobacter spp. and H. cetorum in endangered freshwater finless porpoises.

Abstract
Pseudomonas chlororaphis GP72 is a root-colonizing biocontrol strain isolated from the green pepper rhizosphere that synthesizes two phenazine derivatives: phenazine-1-carboxylic acid (PCA) and 2-hydroxyphenazine (2-OH-PHZ). The 2-OH-PHZ derivative shows somewhat stronger broad-spectrum antifungal activity than PCA, but its conversion mechanism has not yet been clearly revealed. The aim of this study was to clone and analyze the phenazine biosynthesis gene cluster in this newly found strain and to improve the production of 2-OH-PHZ by gene disruption and precursor addition. The conserved phenazine biosynthesis core operon in GP72 was cloned by PCR, and the unknown sequences located upstream and downstream of the core operon were detected by random PCR gene walking. This led to a complete isolation of the phenazine biosynthesis gene cluster phzIRABCDEFG and phzO in GP72. Gene rpeA and phzO were insertionally mutated to construct GP72AN and GP72ON, respectively, and GP72ANON collectively. The inactivation of rpeA resulted in a fivefold increase in the production of PCA, as well as 2-OH-PHZ. The addition of exogenous precursor PCA to the broth culture, to determine the conversion efficiency of PCA to 2-OH-PHZ under current culture conditions, revealed that PCA had a positive feedback effect on its own accumulation, leading to enhanced synthesis of both PCA and 2-OH-PHZ. The production of 2-OH-PHZ by GP72AN increased to about 170 μg ml(-1), compared with just 5 μg ml(-1) for the wild type. The hypothesis of biosynthetic pathway for 2-OH-PHZ from PCA was confirmed by identification of 2-hydroxyphenazine-1-carboxylic acid as an intermediate in the culture medium of the high-phenazine producing GP72AN mutant.

Abstract
AIM: To investigate the occurrence of postoperative complications of gastric cancer surgery, and analyze the potential causes of reoperation for early postoperative complications.
METHODS: A total of 1639 patients who underwent radical or palliative gastrectomies for gastric cancer were included in the study. The study endpoint was the analysis of postoperative complications in inpatients.
RESULTS: About 31% of patients had early postoperative complications, and complications of infection occurred most frequently. Intra-abdominal hemorrhage and anastomotic leak were the main causes of reoperation, which accounted for about 2.2%. Mortality was 11.1% in the reoperation group, but was only 0.8% in other patients. The duration of postoperative stay in hospital was significantly longer and the total expenditure was markedly higher in the patients who underwent reoperation (P < 0.001). There was no significant association of any available factors in this study with the high rate of reoperation.
CONCLUSION: Reoperation significantly increases the mortality rate and raises the burden of the surgical unit. More prospective studies are required to explore the potential risk factors.

Abstract
Background The selection of an anastomosis method after a distal gastrectomy is a highly debatable topic; however, the available documentation lacks the necessary research based on a comparison of early postoperative complications. This study was conducted to investigate the difference of early postoperative complications between Billroth I and Billroth II types of anastomosis for distal gastrectomies. Methods A total of 809 patients who underwent distal gastrectomies for gastric cancer during four years were included in the study. The only study endpoint was analysis of in-patients' postoperative complications. The risk adjusted complication rate was compared by POSSUM (Physiological and operative severity score for enumeration of morbidity and mortality) and the severity of complications was compared by Rui Jin Hospital classification of complication. Results Complication rate of Billroth II type of anastomosis was almost double of that in Billroth I (P = 0.000). Similarly, the risk adjusted complication rate was also higher in Billroth II group. More severe complications were observed and the postoperative duration was significantly longer in Billroth II type (P = 0.000). Overall expenditure was significantly higher in Billroth II type (P = 0.000). Conclusion Billroth II method of anastomosis was associated with higher rate of early postoperative complications. Therefore, we conclude that the Billroth I method should be the first choice after a distal gastrectomy as long as the anatomic and oncological environment of an individual patient allows us to perform it. However more prospective studies should be designed to compare the overall surgical outcomes of both anastomosis methods.

Abstract
AIM: To investigate the role of sex hormones in the early postoperative complications of gastrointestinal diseases.
METHODS: A total of 65 patients who underwent operations for gastric and colorectal diseases (mainly malignant diseases) were included in the study. Peripheral venous blood samples were collected at different times for analysis of estradiol, testosterone and progesterone. The only study endpoint was analysis of postoperative complications.
RESULTS: Patients of both sexes were uniform but postoperative complication rate was significantly higher in female patients (P = 0.027). There was no significant association of estradiol and progesterone with postoperative complications. Testosterone levels in complicated patients were significantly lower than in uncomplicated patients (P < 0.05). Area under the receiver operating characteristic curve showed that a lower value of testosterone was a predictor for higher complication rate (P < 0.05), and a lower value of testosterone at later times after surgery was a better predictor of complications.
CONCLUSION: Patients with low testosterone level were prone to higher postoperative complications, which was evident in both sexes. However, further studies are necessary to support this result.

Abstract
We applied physiological and operative severity score for the enumeration of morbidity and mortality (POSSUM) to evaluate overall surgical outcome and investigated the role of gender for early post-operative complications in gastric cancer surgery. The data from a total of 357 patients of gastric cancer were analysed by univariate and multivariate analysis. Post-operative complications were recorded according to definition of POSSUM. Post-operative complications of male and female patients were compared separately. The observed to estimated morbidity ratio (O:E) was 1.01. Among the pre-operative variables, patient gender was one of the independent risk factors for a higher rate of post-operative complications (risk ratio 1.777, P = 0.024). Post-operative complication was significantly higher in female patients. Similarly, post-operative length of stay was significantly longer and more severe complications were observed in female patients (P = 0.03). In conclusion, POSSUM system is a valid algorithm for risk-adjusted surgical audit. We conclude that a patient's gender influences the early post-operative complications after gastric cancer surgery. A detailed understanding on disparity of early post-operative complications between men and women may provide valuable information to improve surgical outcome of gastric cancer. However, results of this study need further confirmation by a prospective study involving a larger cohort.

Abstract
OBJECTIVES To investigate the value of multidetector-row computed tomography (MDCT) in the preoperative T and N staging of gastric carcinoma and to further investigate the clinicopathological factors affecting the diagnostic accuracy. METHODS Seven hundred ninety gastric carcinoma patients underwent preoperative MDCT examination. The results of MDCT were compared with surgical and pathological findings. RESULTS Early gastric carcinoma patients whose primary tumor was detected by MDCT had higher incidence of lymph node metastasis, larger tumor size, and deeper invasion. The overall accuracy of MDCT in determining T stage of gastric carcinoma was 73.80% (T1 45.93%, T2 53.03%, T3 86.49%, and T4 85.79%). The overall accuracy of MDCT in preoperative N staging was 75.22% (N0 76.17%, N1 68.81%, and N2 80.63%). The overall diagnostic sensitivity, specificity, and accuracy of MDCT for determining lymph node metastasis was 86.26%, 76.17%, and 82.09%, respectively. Multivariate analysis showed that the diagnostic sensitivity of MDCT in determining lymph node metastasis related with tumor size, N stage, and number of metastatic lymph nodes. CONCLUSIONS The clinical value of MDCT in the preoperative T and N staging of gastric carcinoma is relatively high. MDCT can be the first choice for the preoperative evaluation of patients with gastric carcinoma.

Abstract
AIMS The physiological effects of glucocorticoids in a given tissue are driven by the local level of the active glucocorticoid, which is determined by two sources: the plasma cortisol in human (or corticosterone in rodents) and the cortisol produced locally through 11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1) activity. Because of the circadian variation of plasma glucocorticoids, the pharmacological efficacy of 11beta-HSD1 inhibition may depend on the time of the day for inhibitor administration. METHODS The circadian profile of corticosterone was established in lean and diet-induced obesity (DIO) C57BL/6 mice from blood collected at different time of the day. 11beta-HSD1 enzyme activity was also measured throughout the day in DIO mice. To determine the optimal timing for administration of an 11beta-HSD1 inhibitor to obtain maximum efficacy, we used a DIO mouse model and a small molecule inhibitor of 11beta-HSD1 from our thiazolinone series. Based on the circadian profile of corticosterone obtained, we administered the 11beta-HSD1 inhibitor to these animals at different times of the day and evaluated the effects on plasma glucose levels and glucose tolerance. RESULTS We report that corticosterone circadian rhythm was similar between lean and DIO C57BL/6 mice, and 11beta-HSD1 enzyme activity undergoes minimal variations throughout the day. Interestingly, the compound exhibited maximum efficacy if dosed in the afternoon when plasma corticosterone is high; the morning dosing when plasma corticosterone is low did not lead to efficacy. CONCLUSION These data suggest that because of the circadian rhythm of circulating glucocorticoids, the time of the day for 11beta-HSD1 inhibitor administration is important in achieving efficacy.

Abstract
BACKGROUND Hypertriglyceridaemia, commonly found in subjects with obesity and type 2 diabetes mellitus, is associated with increased risk of coronary heart disease (CHD). Apolipoprotein C-III (apoC-III) plays an important role in regulating the metabolism of triglyceride-rich lipoproteins (TRLs) and may provide a new approach to assessing hypertriglyceridaemia. AIMS We review the role of apoC-III in regulating TRL metabolism and address the potential importance of apoC-III in clinical practice. DISCUSSION Hypertriglyceridaemia is chiefly a consequence of alterations in the kinetics of TRLs, including overproduction and delayed clearance of very-low density lipoprotein (VLDL). ApoC-III is an inhibitor of lipoprotein lipase and of TRLs remnant uptake by hepatic lipoprotein receptors. Elevated apoC-III, usually resulting from hepatic overproduction of VLDL apoC-III, may cause accumulation of plasma TRLs leading to hypertriglyceridaemia. The results from recent observational studies demonstrate that apoC-III is a strong predictor of risk for CHD, but this chiefly relates to apoC-III in apoB-containing lipoproteins. Lifestyle and pharmacological intervention can correct hypertriglyceridaemia by a mechanism of action that regulates apoC-III transport. CONCLUSIONS Targeting apoC-III metabolism may therefore be an important, new therapeutic approach to managing dyslipidaemia and CHD risk in obesity, insulin resistance and type 2 diabetes mellitus. However, further work is required to establish the practical aspects of measuring apoC-III in routine laboratory service and the precise therapeutic targets for serum total apoC-III and/or apoC-III in apoB-containing lipoproteins. While showing much promise as a potentially useful cardiovascular risk factor, apoC-III is not yet ready for prime time use in clinical practice.

Abstract
AIM: To identify the risk factors predicting lymph node metastasis in early gastric carcinoma (EGC) and to investigate the value of multidetector-row computed tomography (MDCT) in the preoperative assessment of lymph node metastasis.
METHODS: Relationship between the clinicopathological parameters and lymph node metastasis in 109 EGC patients (male 64, female 45, mean age 56) who underwent preoperative MDCT examination and curative gastrectomy was retrospectively analyzed. In addition, the results of lymph node status evaluated by MDCT were compared with pathologic findings.
RESULTS: The incidence rate of lymph node metastasis was 15.60% in EGC patients. The incidence of lymph node metastasis in submucosal carcinoma was significantly higher than that in mucosal carcinoma (25.00% vs 9.23%, P = 0.026). However, the lymph node metastasis in EGC was not closely related to the gender, age of patients, tumor size, macroscopic type, tumor location, and histological type. Receiver operating characteristic (ROC) analysis further showed that the accuracy of tumor size for determination of lymph node metastasis in EGC was relatively low (area under ROC curve was 0.63). The overall accuracy of MDCT in preoperative N staging of EGC was 82.6% (N0 85.9%, N1 64.3%, N2 66.7%, respectively). The diagnostic sensitivity, specificity and accuracy of MDCT for determining lymph node metastases of EGC were 70.6%, 85.9%, and 83.5%, respectively. The diagnostic sensitivity of MDCT for determining lymph node metastasis was 50.0% in patients with solitary lymph node metastasis, while 88.89% in those with more than one lymph node metastasis. In 5 EGC patients, the lymph node metastasis was not detected by MDCT. However, the tumor size of all these 5 patients was larger than or equal to 2 cm in diameter, and both of the two mucosal carcinomas belonged to depressed EGC.
CONCLUSION: Although the clinical value of MDCT in the preoperative assessment of lymph node metastasis in patients with EGC is relatively high, we still must pay great attention to the value of lymph node metastasis-associated clinicopathological parameters in predicting lymph node status when the minimally invasive therapy is to be performed for patients with EGC.

Abstract
Cell-based immunizations are often used when membrane antigens are difficult to purify. To confirm that an antibody binding to the surface of a cell line is, in fact, binding to the desired antigen, FACS can be performed independently on two cell lines, a transfected cell line expressing the antigen of interest and a control cell line not expressing the antigen. Antibodies binding only to the transfected cell line are then selected for further analysis. This approach can be challenging if a large number of antibodies need to be screened and the antibody quantities are limited. Here we describe a novel method that combines the above two steps of FACS screening into a single step, based on the use of two fluorochromes, CMFDA and CMTMR, to stain transfected and control cell lines, respectively. Antibodies conjugated to a thirdfluorochrome are then added to the combined cells, followed by three-color FACS analysis. The newly modified FACS method is simple, sensitive, and high throughput. It can be used for antibody screening in multiple cell lines simultaneously.
