Abstract
Objective: To establish the nutrition literacy core items for preschool children in China. Methods: The framework system and preliminary items of nutrition literacy were established through literature review and experts consultation. E-Delphi method was used to determine the nutrition literacy items. Nine experts in the field of nutrition, child and adolescent health, health education were invited to score the importance of each nutrition literacy item via Email. The judgment basis and familiarity of experts towards the items, active coefficient, authority coefficient and harmony coefficient were evaluated and analyzed to generate the final list of nutrition literacy items. Results: In the first round of E-Delphi consultation, the active coefficient and authority coefficient were 88.9%(8/9) and(0.88±0.07).The harmony coefficient was 0.350 (χ2=36.432, P=0.001). In the second round, the active coefficient and authority coefficient were 100% (9/9) and (0.89±0.11).The harmony coefficient was 0.347 (χ2=34.330, P<0.001). After qualitative and quantitative analyses, we identified the final list of nutrition literacy items consisting of two scales (basic knowledge, lifestyles and dietary behaviors), six subscales (food knowledge, food characteristic, food choice, dietary behavior, dietary safety, and physical activity)with 14 items in total. Conclusion: The framework system and core items of nutrition literacy are established for Chinese preschool children, which could provide a reference basis for the implementation of nutrition education project and the establishment of standardized evaluation tools.

Abstract
Objective: To study the bacterial pathogen, the optimal plan of antibacterial drugs and the prognostic factors in patients with liver cirrhosis combined with bacterial pneumonia. Methods: Data of 324 cases with liver cirrhosis from the Department of Traditional and Western Medical Hepatology, the Third Hospital of Hebei Medical University were collected, including 217 cases of bacterial pneumonia. Baseline characteristics of the patients, factors affecting the efficacy of antibacterial treatment and prognosis were compared and analyzed. Logistic regression analysis was used to screen and predict the antibacterial efficacy indicators and a prediction model was established. Receiver operating characteristic curve was used to evaluate the value of the established model and Child-Turcortte-Pugh, model for end-stage liver disease, and model for end-stage liver disease combined with serum sodium concentration predict the therapeutic efficacy. Results: Chronic HBV and HCV infections were the main causes of cirrhosis, followed by cryptogenic cirrhosis and alcoholic cirrhosis. Diabetes, cardio-cerebrovascular and chronic obstructive pulmonary disease were susceptible factors for bacterial pneumonia. As infection occurred, the ratio of neutrophils to lymphocytes, serum C-reactive protein, procalcitonin, alanine aminotransferase, and total bilirubin levels had increased significantly. The results of pathogenic analysis showed that the top three pathogenic bacteria were Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Staphylococcus aureus. The resistance rate of Klebsiella pneumoniae to ceftriaxone was 50.0%, and that of ceftazidime, cefepime, and cefoperazone sulbactam were 27.8%. Imipenem and piperacillin tazobactam containing β-lactamase inhibitors were the most effective antibacterial therapies. Regression analysis showed that age, procalcitonin, and albumin was significantly correlated with antibacterial effects. The PAA model was established and had predicted the efficacy of Child-Turcortte-Pugh, model for end-stage liver disease, and model for end-stage liver disease combined with serum sodium. The specificity and sensitivity of the PAA was confirmed to be 94.12% and 93.62%, which was significantly higher than other models. Conclusion: The main common pathogenic bacterium of cirrhosis combined with bacterial pneumonia is Klebsiella pneumonia (G-bacilli). In addition, gram positive cocci (Staphylococcus aureus) and other are also visible. The elderly, diabetics and patients using hormones are prone to secondary fungal infections. Age, procalcitonin and serum albumin can accurately predict the antibacterial effect, guide clinical treatment and judge the prognosis of the established PAA model.

Abstract
Objective: To explore the feasibility of using faster regional convolutional neural network (Faster R-CNN) to evaluate the status of circumferential resection margin (CRM) of rectal cancer in the magnetic resonance imaging (MRI). Methods: This study was registered in the Chinese Clinical Trial Registry (ChiCTR-1800017410). Case inclusion criteria: (1) the positive area of CRM was located between the plane of the levator ani, anal canal and peritoneal reflection; (2) rectal malignancy was confirmed by electronic colonoscopy and histopathological examination; (3) positive CRM was confirmed by postoperative pathology or preoperative high-resolution MRI. Exclusion criteria: patients after neoadjuvant therapy, recurrent cancer after surgery, poor quality images, giant tumor with extensive necrosis and tissue degeneration, and rectal tissue construction changes in previous pelvic surgery. According to the above criteria, MRI plain scan images of 350 patients with rectal cancer and positive CRM in The Affiliated Hospital of Qingdao University from July 2016 to June 2019 were collected. The patients were classified by gender and tumor position, and randomly assigned to the training group (300 cases) and the validation group (50 cases) at a ratio of 6:1 by computer random number method. The CRM positive region was identified on the T2WI image using the LabelImg software. The identified training group images were used to iteratively train and optimize parameters of the Faster R-CNN model until the network converged to obtain the best deep learning model. The test set data were used to evaluate the recognition performance of the artificial intelligence platform. The selected indicators included accuracy, sensitivity, positive predictive value, receiver operating characteristic (ROC) curves, areas under the ROC curves (AUC), and the time taken to identify a single image. Results: The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of the CRM status determined by the trained Faster R-CNN artificial intelligence approach were 0.884, 0.857, 0.898, 0.807, and 0.926, respectively; the AUC was 0.934 (95% CI: 91.3% to 95.4%). The Faster R-CNN model's automatic recognition time for a single image was 0.2 s. Conclusion: The artificial intelligence model based on Faster R-CNN for the identification and segmentation of CRM-positive MRI images of rectal cancer is established, which can complete the risk assessment of CRM-positive areas caused by in-situ tumor invasion and has the application value of preliminary screening.

Abstract
Objective: To investigate the effect and molecular mechanism of circular RNA-UBXN7 (circ_UBXN7) on the proliferation, migration and apoptosis of hepatocellular carcinoma cells. Methods: Circ_UBXN7 expression in the tissues and cells of hepatocellular cancer was detected by quantitative real-time polymerase chain reaction (qRT-PCR), and the relationship between circ_UBXN7 expression and clinicopathological features, including age, gender, tumor volume, pathological classification, staging, and lymph node metastasis was analyzed. The full-length sequence of circ_UBXN7 with lentivirus carrying lenti circ_UBXN7 and lenti circ_UBXN7 shRNA was constructed to transfect hepatocellular cell lines (HepG2 and Huh-7), respectively. CCK-8 experiments were performed to detect the ability of up- or down-regulation of circ_UBXN7 on the proliferation of HEPG2 and HUH-7 cells. Annexin V / PI experiment was used to detect the changes in apoptosis of HEPG2 and HUH-7 cells after up-regulation or down-regulation of circ_UBXN7 expression. JC-1 assay was used to detect the changes in mitochondrial potential energy of HEPG2 and HUH-7 cells after up-regulation or down-regulation of circ_UBXN7 expression. Transwell was used to detect the migration ability of HEPG2 and HUH-7 cells after up-regulation or down-regulation of circ_UBXN7 expression. Western blotting was used to detect the expressional change of TWIST, E-cadherin, N-cadherin and vimentin. Statistical analysis: The expression levels of circ_UBXN7 and clinicopathological features were measured by chi-square test. Two groups were compared by t-test and three groups and above were compared by single factor analysis of variance. LSD method was used for comparison between groups. Results: The expression of circ_UBXN7 in liver cancer tissues was significantly higher than adjacent tissues, and its expression level was significantly positively correlated with tumor volume, stage, and lymph node metastasis (P < 0.05). Lenti-circ_UBXN7 had up-regulated the expression of circ_UBXN7 in HEPG2 and HUH-7 cells and promoted cell proliferation. Lenti-circ_UBXN7-shRNA had down-regulated the expression of circ_UBXN7 and induced apoptosis. Lenti-circ_UBXN7-shRNA had reduced the mitochondrial membrane potential of cells. Lenti-circ_UBXN7 had promoted cell migration, while lenti-circ_UBXN7-shRNA had inhibited cell migration. Lenti-circ_UBXN7 had induced increased expression of Twist, N-cadherin, and Vimentin proteins, and reduced the expression of E-cadherin protein. Lenti-circ_UBXN7-shRNA had opposite effects on the expression levels of each protein. Starbase V2.0 software showed that miR-203a and circ_UBXN7 had potential binding sites, and miR-203a and circ_UBXN7 expression levels were negatively correlated in HEP G2 and HUH-7 cells. Conclusion: circ_UBXN7 plays an important role in promoting the occurrence and development of liver cancer, and is expected to become a potential target for the treatment of liver cancer.

Abstract
Objective: To calculate both the epidemic and intensity thresholds for different levels in Beijing and to establish a tiered alert system in the 2018-2019 influenza season as well as to evaluate the performance of calculated thresholds. Method: Weekly count of influenza-like illness and percentage of influenza-like illness (ILI%) of the last five influenza seasons were modeled by 'moving epidemic method' (MEM) to calculate the influenza epidemic and intensity thresholds at different levels. A cross-validation procedure was used to evaluate the performance. Indicators of Matthew correlation coefficient, Youden's index, sensitivity and specificity were calculated. Results: For weekly count of influenza-like illness, data showed that the epidemic threshold for 2018-2019 influenza season was 12 984 and the medium, high and very high intensity thresholds were 22 503, 37 589, 47 157, respectively. Matthew correlation coefficient of the epidemic threshold was 62% and youden's index as 60% , sensitivity as 69%, specificity as 91%. Data on weekly ILI%, the epidemic threshold for 2018-2019 influenza season was 1.66%, with medium, high and very high intensity thresholds as 2.46%, 3.84% and 4.66%, respectively. The overall Matthew correlation coefficient of the epidemic threshold was 59%, with 54% for the Youden's index, sensitivity as 60% and specificity as 94%. Conclusions: MEM produced a good specific signal for detecting the influenza epidemics and the accuracy of the method was acceptable. The early warning performance regarding the application of weekly count on influenza-like illness was slightly better than ILI%. This method could be applied in the practical influenza epidemic alert "work in Beijing" .

Abstract
BACKGROUND AND AIMS We aim to quantify the variation in root distribution in a set of 35 experimental wheat lines. We also compared the effect of variation in hydraulic properties of the rhizosphere on water uptake by roots. METHODS We measured the root length density and soil drying in 35 wheat lines in a field experiment. A 3D numerical model was used to predict soil drying profiles with the different root length distributions and compared with measured soil drying. The model was used to test different scenarios of the hydraulic properties of the rhizosphere. RESULTS We showed that wheat lines with no detectable differences in root length density can induce soil drying profiles with statistically significant differences. Our data confirmed that a root length density of at least 1 cm/cm3 is needed to drain all the available water in soil. In surface layers where the root length density was far greater than 1 cm/cm3 water uptake was independent of rooting density due to competition for water. However, in deeper layers where root length density was less than 1 cm/cm3, water uptake by roots was proportional to root density. CONCLUSION In a set of wheat lines with no detectable differences in the root length density we found significant differences in water uptake. This may be because small differences in root density at depth can result in larger differences in water uptake or that the hydraulic properties of the rhizosphere can greatly affect water uptake.

Abstract
Objective: To explore the prevalence risk factors of Beijing genotype Mycobacterium tuberculosis (MTB) in Beijing and its correlation with second-line anti tuberculosis drug resistance. Methods: A total of 1 140 clinical MTB positive strains were collected from various districts in Beijing, and the drug sensitivity was detected by proportion method. Beijing genotype and non Beijing genotype MTB were identified by the method of Spoligotyping. Using SPSS 22.0 statistical software, chi square test or Fisher exact probability test was used to analyze the experimental data. Results: Among 1 140 MTB clinical isolates, 941 (82.5%) were Beijing genotype MTB, 199 were non Beijing genotype MTB. There were 663 males (70.5%) in Beijing genotype and 124 males (62.3%) in non Beijing genotype strains. There were significant differences in the proportion of males between the two genotypes [P=0.021, OR (95% CI):1.442 (1.048-1.985)]. There were 441 floating population (46.9%) in Beijing genotype MTB and 78 floating population (39.2%) in non Beijing genotype MTB. There was a significant difference in the proportion of floating population between the two genotypes [P=0.048,OR (95%CI):1.368(1.001-1.869)]. There were 129 patients (13.7%) aged 65 or older in Beijing genotype MTB, 40 patients (20.1%) aged 65 or older in non Beijing genotype MTB. The difference was statistically significant [P=0.021, or (95% CI): 0.631 (0.426-0.936)]. The resistance drug rates of Levofloxacin (Lfx), Amikacin (Am), Capreomycin (Cm), Para-aminosalicylic (PAS) in Beijing genotypes were 5.5% (52/941), 1.3% (12/941), 3.2% (30/941) and 3.0% (28/941), respectively, and those of non Beijing genotypes were 10.6% (21/199), 8.5% (17/199, 12.6% (25/199) and 11.6% (23/199), the difference was statistically significant (all P<0.05). There were 58 (6.2%) multidrug-resistant (MDR) strains in Beijing genotype MTB and 19 (9.5%) multidrug-resistant strains in non Beijing genotype. There was no significant difference in the proportion of MDR strains between Beijing genotype and non Beijing genotype (P>0.05). Conclusions: Beijing genotype MTB is widespread in Beijing and has a higher proportion in male population and floating population. Compared with non Beijing genotype, Beijing genotype MTB has a lower resistance rate to Lfx, Am, Cm and PAS, and there is no significant difference in the proportion of MDR-TB patients between the two genotypes.

Abstract
The aim of this study was to optimize the protein hydrolysates from chicken liver with xylose under Maillard reaction (MR) conditions using response surface methodology. The correlation between the browning degree, grafting degree, and the antioxidant activities of the Maillard reaction products (MRPs) was investigated. The optimal reaction conditions were achieved with a reaction temperature of 138.78°C, an initial pH of 7.99, and a reaction time of 93.14 min. The grafting degree (41.98%) and browning degree (2.582) of chicken liver protein hydrolysate MRPs (CLPHM) were notably higher (P < 0.05) than those of protein MRPs (CLPM) and were significantly lower (P < 0.05) than those of sonicated hydrolysate MRPs (SCLPHM). The reducing power, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and hydroxyl radical scavenging of CLPM, CLPHM, and SCLPHM were significantly higher (P < 0.01) than those of the protein or hydrolysate substrates. The grafting degree and browning degree of CLPM, CLPHM, and SCLPHM had positive correlations with DPPH and hydroxyl radical scavenging activity. Hence, this study could enhance the added value of chicken liver by exhibiting the enhancements from ultrasound pretreatment and the MR. MRPs could have an effective and potential application in the food industry.

Abstract
BACKGROUND AND AIMS We aim to quantify the variation in root distribution in a set of 35 experimental wheat lines. We also compared the effect of variation in hydraulic properties of the rhizosphere on water uptake by roots. METHODS We measured the root length density and soil drying in 35 wheat lines in a field experiment. A 3D numerical model was used to predict soil drying profiles with the different root length distributions and compared with measured soil drying. The model was used to test different scenarios of the hydraulic properties of the rhizosphere. RESULTS We showed that wheat lines with no detectable differences in root length density can induce soil drying profiles with statistically significant differences. Our data confirmed that a root length density of at least 1 cm/cm3 is needed to drain all the available water in soil. In surface layers where the root length density was far greater than 1 cm/cm3 water uptake was independent of rooting density due to competition for water. However, in deeper layers where root length density was less than 1 cm/cm3, water uptake by roots was proportional to root density. CONCLUSION In a set of wheat lines with no detectable differences in the root length density we found significant differences in water uptake. This may be because small differences in root density at depth can result in larger differences in water uptake or that the hydraulic properties of the rhizosphere can greatly affect water uptake.

Abstract
Objective:To investigate the clinical characteristics, imaging features and treatment of neurogenic tumor in chilehood and to improve the experience in diagnosis and treatment for the disease. Method:The twenty-nine inpatients of histopathologically proven neurogenic tumor from January 2015 to December 2018 were retrospectively analyzed. The pathological types, clinical characteristics, imaging findings, and management were analyzed. Result: There were five cases of schwannoma aged from 9 years to 14 years, five cases of neurofibroma aged from 9 months to 9 years, and nineteen cases of neuroblastic tumor aged from 3 months to 5 years in our series. The chief manifestations were soft tissue masses, snore, and Honer syndrome. As the tumors had different components pathologically, on scans they presented as masses with heterogeneous density. Schwannoma showed as oval masses with clear margins, with the characteristic of"tail sign". The imaging findings of neurofibromas showed unclear boundaries and plexiform neurofibromas showed multiple clumps with visible separation. The ultrasonography of neuroblastic tumor was characterized by hypoechoic, heterogeneous and spotty calcification. All the cases underwent surgical resections. In 5 cases of schwannoma, it was confirmed that the tumors originated from the vagus nerve during the operation, which could be completely removed without postoperative complications. Two cases of neurofibromas were completely resected, 2 cases were only partially resected, and 1 case which located at the entrance of the esophagus was resected under supportive laryngoscopic for three times. Thirteen of 19 children with neuroblastogenic tumors underwent resection in our department after chemotherapy, and 2 patients with postoperative recurrence underwent another operation. Conclusion:Neuroblastoma is the most common neurogenic tumor in the head and neck of children. Most neurogenic tumors have their corresponding characteristics on imaging and should be differentiated. Schwannoma has clear boundary and intact capsule, so it is easier to complete resection. The neurofibroma is commonly difficult to remove with safety margin because of its unclear boundaries. Neuroblastoma should be treated according to the lesion range and stage. Most of the lesions are difficult to remove completely due to the wide range, peripheral blood vessels and important nerves. So preoperative chemotherapy is generally required.

Abstract
Objective: To analyze the influencing factors of acute gastroenteritis outbreaks caused by norovirus in Beijing from 2014 to 2018. Methods: Data of acute gastroenteritis events caused by norovirus in Beijing from April 2014 to March 2018 were collected. Unconditional logistic regression model was conducted to identify the risk factors of the outbreaks. Results: A total of 765 acute gastroenteritis epidemics caused by norovirus were reported in Beijing, in which 85.88% (657/765) were cluster events and 14.12% (108/765) were outbreaks. Among the outbreaks, 70.37% (76/108) were reported in 2017; 84.26% (91/108) were reported in winter and spring; 88.89% (96/108) were reported in kindergartens, primary or secondary schools; 81.48% (88/108) were through person-to-person transmission; 93.52% (101/108) were caused by norovirus GⅡ infection. The risk of outbreaks in suburban and out suburb area were 1.84 times (95%CI: 1.13-3.02) and 3.78 times (95%CI: 1.62-8.82) as high as that in urban area, respectively. The risks of outbreaks in primary, secondary schools and other institutions were 6.26 times (95%CI: 3.53-11.10), 14.98 times (95%CI: 6.23-36.01) and 8.71 times (95%CI: 3.07-24.71) as high as that in kindergartens, respectively. The risk of outbreak in which patients having lower hospital visiting rate than the median rate of all events was 2.29 times than that in the context of having higher hospital visiting rate (95%CI:1.42-3.68). The risk of foodborne outbreak was 14.55 times as high as that transmitted through person-to-person (95%CI: 3.15-67.07). Conclusion: Measures such as strengthening the prevention and control of norovirus outbreaks in suburbs, primary schools, secondary schools and other institutions, promoting patients to visit the hospital actively, improving the management of foodborne events and kitchen workers should be taken to reduce the incidence of acute gastroenteritis outbreaks caused by norovirus.

Abstract
Objective: To explore the clinical features, the risk factors of mortality and drug resistance of the isolates in patients with group B streptococcus (GBS) meningitis. Methods: A retrospective analysis was performed in 96 children with GBS meningitis (46 males and 50 females) at Beijing Children's Hospital Affiliated to Capital Medical University from January 2013 to October 2017. The clinical characteristics, prognosis and drug resistance were reviewed and analyzed. According to the onset time, the patients were divided into early onset disease (EOD, 0-6 days), late onset disease (LOD, 7-89 days) and very late onset disease (VLOD, 90 days-16 years), the clinical features were compared. According to the results of cranial imaging examination, the patients were divided into two groups: those with neurological complications and those without neurological complications. The influencing factors of neurological complications were analyzed. According to the outcome of 28 days after discharge, patients were divided into death group and survival group. The risk factors of mortality were analyzed by multivariate Logistic regression analysis. Non-numeric variables were analyzed with χ(2) test or Fisher's exact test. Numeric variable between groups were compared with nonparametric test. Results: A total of 96 patients were enrolled, including 18 (19%) EOD, 71 (74%) LOD and 7 (7%) VLOD cases. The median age of EOD cases was 2 days, with a range from 0 to 6 days. The median age of LOD cases was 31 days, with a range from 7 to 81 days. The median age of VLOD cases was 153 days, with a range from 95 to 214 days. Before the onset of the disease, the mother had mastitis in 6 cases and premature rupture of membranes in 6 cases. The common clinical manifestations of patients were fever (95%, 91/96), anorexia (65%, 62/96), seizure (56%, 54/96), and consciousness changes (36%, 35/96). The differences were statistically significant in gender (13/18 vs. 28/71 vs. 5/7, χ(2)=7.705, P=0.024), the number of cases who was admitted to intensive care unit (ICU) (5/18 vs. 31/71 vs. 0, χ(2)=6.065, P=0.042) and peripheral blood leukocyte (12(4, 18)×10(9)/L vs. 6(3, 11)×10(9)/L vs. 13(6, 17)×10(9)/L, H=9.885, P=0.007) in EOD group, LOD group and VLOD group. Cranial imaging was performed in 94 patients, 60 patients (64%) developed neurological complications, including subdural effusion (31/94, 33%), followed by intracranial hemorrhage (26/94, 28%), cerebral softening (19/94, 20%), cerebral atrophy (15/94, 16%), ependinitis (8/94, 9%) and hydrocephalus (4/94, 4%). By univariate χ(2) test analysis, seizure (63% (38/60) vs.41% (14/34), χ(2)=4.310, P=0.038) was a risk factor of neurological complications. Within 28 days after discharge, 88 patients survived and 8 patients died, with a fatality rate of 8%. The independent risk factors for the death were septic shock (OR: 9.548, 95% CI 1.439-63.356, P=0.019) and respiratory failure (OR: 7.053, 95% CI 1.160-42.888, P=0.034). All of isolates were susceptible to penicillin (68/68), ceftriaxone (47/47), cefepime (50/50), vancomycin (60/60) and linezolid (54/54), while the rates of resistance to tetracycline, levofloxacin, clindamycin and erythromycin were 5/12, 17/45, 38/46 and 32/37, respectively. Conclusions: The main type of GBS meningitis is late onset cases. The incidence of neurological complications was high. The independent risk factors for death were septic shock and respiratory failure. The strains were severely resistant to clindamycin and erythromycin.

Abstract
Objective: To evaluate the effect of a community-based intervention supporting type 2 diabetes mellitus patients in their self-management of the disease. Methods: This research was a randomized controlled trial conducted in communities in Fangshan District, Beijing, China. Adult patients with type 2 diabetes from 17 communities in 4 sub-district of Fangshan District were randomly assigned to either the intervention or control group. Participants in the intervention group participated in a three-month group-based diabetes self-management intervention service. Data were collected both in intervention and control group at baseline and after the intervention to evaluate the effect of the intervention. A questionnaire survey was completed by all participants to collect their demographic information, diabetes related health behaviors and skills. A physical examination and lab testing including height, weight, blood pressure, and waist circumference as well as HbA1c, fasting blood glucose, lipid profile were conducted before and after the intervention. Results: A total of 500 valid questionnaires were received, including 259 in the intervention group and 241 in the control group. Patients in the intervention group who learned how to conduct the self-monitoring of blood glucose increased from 56.76% (n=147) to 87.26% (n=226) after the intervention, higher than that of control group (63.07%, n=152) (P<0.001). 69.50% (n=180) patients in intervention group had blood glucose monitor at home, which was 60.62% (n=157) prior to the intervention and higher than that of control group (57.68%, n=139) (P=0.004). After the intervention, 3.09% (n=8) patients in intervention group ceased to take medicine by themselves, which was 16.22% (n=42) before the intervention, while the control group was 8.30% (n=20) after the intervention (P=0.009). Patients in the intervention group made significant improvements in implementing self monitoring on blood glucose (SMBG), which was increased from one day per week to 2 days per week, and foot self-examination, which increased from 2 days per week to 7 days per week. The body weight of patients in the intervention group reduced 1.62 kg on average after the intervention, while it increased 0.88 kg in the control group. Similar improvement was found in waist circumstance between the intervention and control group (-0.83 cm vs -0.16 m). There was a significant reduction on body weight and waist circumstance in the intervention group (P<0.05). Conclusion: The group activities focusing on people with type 2 diabetes resulted in improvement in their lifestyle and self management behaviors, as well as their body weight and waist circumstance.

Abstract
Objective: To investigate the relationship between the previous cesarean scar thickness, previous cesarean scar defect and the occurrence of uterine rupture for pregnancy women after previous cesarean section and to predict the occurrence of uterine rupture in the third trimester for pregnancy women after previous cesarean section by analyzing the lower uterine segment (LUS) situation or quantitatively measure LUS myometrium thickness. Methods: A total of 154 pregnant women who have a prior cesarean from January 2015 to March 2016 were selected, all of them regularly did the prenatal examination in the pregnancy period and finally gave birth in hospital. By the transvaginal sonograph, the LUS myometrium thickness (transverse and longitudinal thickness) and the size of the previous cesarean scar defect were measured in the first trimester, the LUS myometrium thickness (longitudinal thickness) and qualitatively analysis LUS condition were measured in the third trimester. They were divided into two groups according to the pregnancy outcome: uterine rupture group (found in the cesarean operation or during the pregnancy) and without uterine rupture group (including the vaginal delivery women and those without uterine rupture in the cesarean operation period). The sensitivity and specificity of LUS myometrium thickness in the first trimester and the qualitative analysis LUS situation, the quantitative measurement of LUS myometrium thickness in the third trimester were compared in the prediction of occurrence of uterine rupture (dehiscence or complete rupture). Results: The group without uterine rupture included 134 women (6 vaginal delivery and 128 cesarean delivery), and the group with uterine rupture included 20 women (all of them cesarean delivery). The LUS myometrium thickness in the third trimester in the group without uterine rupture was (1.6±0.5) mm, and was (1.1±0.7) mm in the uterine rupture group (P= 0.004). There were no significant difference between two groups in the mean value of age, height, weight, the interdelivery interval, the LUS myometrium thickness (transverse and longitudinal thickness) in the first trimester. Qualitative analysis of LUS condition had higher specificity (99%), higher positive predictive value (92%), higher negative predictive value (94%) and slightly lower sensitivity (60%) than quantitative measure of LUS myometrium thickness in predicting uterine rupture. Conclusions: Measurement of the LUS myometrium thickness in the first trimester is helpful for predicting the occurrence of uterine rupture, so it is not necessary to terminate the pregnancy because of the thin LUS or the little prior cesarean scar defect in the first trimester. However it should be paid close attention to the LUS situation during the whole gestation. Qualitatively analyzing LUS situation is more meaningful than quantitatively measuring LUS myometrium thickness in predicting the uterine rupture in the third trimester.

Abstract
The aim of present study was to investigate the effect of different times (5 min (UCPP-5), 10 min (UCPP-10), 20 min (UCPP-20), and 30 min (UCPP-30)) of ultrasound treatment on physicochemical, thermal, and antioxidant properties of chicken plasma protein (CPP). UCPP-20 had the highest fluorescence intensity and the lowest particle size. However, no major changes in the subunit compositions and the secondary structure of UCPPs were presented in SDS-PAGE and circular dichroism. The surface hydrophobicity and sulfhydryl content of UCPPs increased significantly (P < 0.05) as compared to those of CPP. With the increasing time of ultrasound treatment, there were more and deeper holes on the protein surfaces. Furthermore, protein modification by ultrasound could improve the thermal properties of UCPPs. Additionally, UCPPs showed a significant increase in antioxidant properties over CPP, especially UCPP-20. These observations indicated that ultrasound treatment was necessary for modification of CPP to meet the requirements for food processing.

Abstract
This study investigated the protein changes in goat milk during the homogenization process using label-free quantification. We quantified 310 and 315 proteins in the control group (CG) and homogenized group (HG), respectively, and 16 proteins were significantly different between the 2 groups. For HG, the goat milk protein particle sizes were smaller and more evenly distributed and exhibited an increase in the regular arrangement of the secondary structures. Proteomics analysis verified that xanthine dehydrogenase and asparaginase-like 1 expression in CG were higher than in HG, whereas the opposite was observed for fructose-bisphosphate aldolase, κ-casein, and β-casein. Significant changes were found in the homogenization-treated goat milk proteome that were related to goat milk glycolysis/gluconeogenesis metabolism. This work provides updated information on the current proteome characteristics of homogenized goat milk, which may be important for applying the protein component of goat milk to human nutrition and health.

Abstract
Objective: To assess the prevalence of HIV infection and related factors in men who have sex with men (MSM) living for ≤5 years in Wenzhou of Zhejiang province. Methods: MSM who were aged ≥16 years, had lived in Wenzhou for ≥3 months and had anal sex and/or oral sex with men in the last 12 months were recruited through respondent-driven sampling (RDS) from February to October in 2015. The MSM recruited completed a questionnaire for the information collection on socio-demographic characteristics, sexual behavior, awareness of HIV and related intervention, mental health status. Blood samples were collected from them for serological detection of HIV and syphilis antibodies. Software SPSS 18.0 was used to analyze HIV infection and related factors. Results: A total of 454 MSM were investigated, 108 of them (23.7%) were HIV positive. There were 267 MSM who lived in Wenzhou for ≤5 years, and 73 of them (27.3%) were HIV positive. Most of them were workers and commercial servants aged ≥25 years with personal monthly income <4 000 yuan and educational level of junior high school or below. According to multiple logistics regression analysis, age of 25-68 years old (OR=12.19, 95%CI: 2.29-65.02), heterosexual behavior in recent 6 months (OR=0.42, 95%CI: 0.18-0.96), believing it was possible to be infected with HIV (OR=0.06, 95%CI: 0.01-0.95), believing it was impossible to be infected with HIV (OR=0.03, 95%CI: 0.01-0.35) and syphilis status (OR=3.32, 95%CI: 1.05-10.52) were the risk factors associated with HIV infection. Conclusion: Compared with MSM who lived in Wenzhou for >5 years, MSM who lived in Wenzhou for ≤5 years had higher HIV infection rate and higher prevalence of risk behavior. It is necessary to conduct targeted intervention among them.

Abstract
The aberrant expression of microRNA-375 (miR-375) has been proved to be associated with carcinogenesis. However, the role of miR-375 in glioblastoma (GBM) remains unknown. The aim of this study was to investigate biological functions and its molecular mechanisms of miR-375 in GBM cells. In this study, real-time PCR results showed that the level of miR-375 expression in GBM tissues and GBM cell lines (U87 and U251) was decreased. Using MTT assay, Transwell migration and invasion assay, we demonstrated that miR-375 overexpression significantly suppress cell proliferation, cell migration and cell invasion capacity in U87 and U251 cells. However, downregulation of miR-375 had reverse effects on cell proliferation, migration and invasion. Targeting association analysis, dual luciferase assay, RT-PCR and western blot analysis results confirmed that miR-375 could target the 3'UTR of Wnt5a mRNA and regulated its protein expression. Further studies also find overexpression of Wnt5a could significantly reverse miR-375-mediated proliferation, migration and invasion on U87 and U251 cells. Therefore, we concluded that miR-375 inhibited the proliferation and invasion of GBM by regulating Wnt5a and might be a possible therapeutic agent for GBM.

Abstract
Bacterial fruit blotch (BFB) of cucurbits, caused by Acidovorax citrulli, is a major threat to commercial watermelon and melon production worldwide. At present, there are at least two genetically distinct sub-populations (group I and II) of A. citrulli that differ in host preference among cucurbit species and copper sensitivity. In this study, we analyzed the pilA gene sequences of 103 A. citrulli strains from China and other countries. Based on these data, we classified all tested A. citrulli strains into three types. The pilA-based type 1 strains in this study coincided with the previously established group I strains; while the type 2 strains coincided with group II strains. Ten strains that did not cluster with group I or II strains were classified into a new type, designated type 3. Based on differences in pilA sequences, we designed a multiplex PCR assay to distinguish the three A. citrulli pilus types. This multiplex PCR assay has proven to be viable for strain typing of 139 A. citrulli strains and for the detection of this pathogen in artificially inoculated seeds and leaves and naturally infected leaves and fruits. This assay proved to be rapid, accurate, reliable and applicable for early distinction of A. citrulli types associated with BFB epidemics. It may also inform the judicious and environmentally sound use of bactericides, especially copper-based compounds.

Abstract
Objective: To improve the clinical recognition of eosinophilic granulomatosis with polyangiitis(EGPA) in clinical manifestations, diagnosis and treatment. Methods: The clinical manifestations, pathological characteristic, imaging manifestations, diagnosis and the therapy of three patients with EGPA were presented. Results: These 3 patients had asthma-like symptoms and extrapulmonary manifestations of systemic vasculitis. They were 20, 40 and 44 years old. All of them were female.They denied exposure or contact. Chest radiographic examination showed that the most common features were nodule shadow and tree-in-bud in the lung. The pathological manifestation was characterized by hypereosinophilia, high total IgE(over 300 KU/L) and high CRP(over 14.1mg/L). The FeNO of 2 patients was over 100ppb. The ANCA of these 3 patients was negative. The pulmonary pathology was observed had eosinophil infiltration in the alveolar, interstitial and vessel for 3 cases. The clinical manifestations were nonspecific. All patients were treated by glucocorticoid and immune-inhibitor(alkylating agents or purine synthesis inhibitors) therapy. Because patients were complicated with other organs involved, they needed long-time treatment. Conclusions: This disease is diverse and complex, with a lack of pathognomonic symptoms. We should highly suspect eosinophilic granulomatosis with polyangiitis, when the patients present severe asthma and eosinophilia. Early detection, early treatment, and the prognosis could be better.

Abstract
Objective: To observe the clinical course of children with juvenile-onset recurrent respiratory papillomatosis (JORRP) until 14 years old. Methods: The clinical data of one hundred and twenty cases treated between Januray 1, 2002 and September 30, 2017 in Beijing Tongren Hospital were analyzed retrospectively. Excluding the deaths and the lost, patients who could be ≥ 5 years without recurrence, were defined as the cured group, and < 5 years with recurrence defined as the recurrent group. Furthermore, using statistical methods to analyze the differences of the age of initial operation, total number of operations, invasive lesion, HPV infection, tracheotomy, airway dissemination after tracheotomy and time of tube wear between the two groups. Results: One hundred and three cases were followed up, except for the six deaths.Numbers of operations in eight cases were ≤2, and ≥3 in eighty nine cases.Peak of the primary surgical age were about 4.5 years old, while the self-healing trend occurred at nine years old. In the cured group, forty three cases were cured, with a curative rate of 41.7% (43/103), and there were all fifty four survivors in the recurrent group.The total number of operations, invasive cases, HPV positive cases and the G score of hoarseness in the recurrent group were higher than those in the cured group (F=13.02, χ(2)=13.04, χ(2)=17.37, Z=-4.59, P<0.05). The number of tracheal dissemination caused by tracheotomy in the recurrent group (66.7%, 27.8%)was more than that in the cured group (χ(2)=16.01, P<0.05). Compared with the time of wearing a tracheostomy tube in cured group, the recurrent group was longer ((3.4±3.1) years vs (8.3±6.7) years, χ(2)=7.19, P<0.05). Conclusions: 41.7% of the patients had no relapse for at least five years.There exsisted differences between the cured and recurrent group in the following aspects: the total numbers of surgery, the agression of the lesions, tracheal intratracheal dissemination after tracheotomy, the time of tracheotomy, the HPV typing and the G grading of hoarseness.

Abstract
Objective: To compare the efficacy and safety of anatomic hepatectomy and non-anatomic hepatectomy in the treatment of single small Hepatocellular carcinoma with MVI. Methods: The clinical data of 84 patients with single small Hepatocellular carcinoma with MVI in Beijing Chaoyang Hospital between January 2008 and December 2013 were retrospectively analyzed. Patients undergoing anatomical hepatectomy were enrolled in the AR group, and the patients undergoing non-anatomic hepatectomy were enrolled in the NR group. The efficacy and survival rate of the two groups were compared. Results: (1) Operation time, numbers of patients with volume of intraoperative blood loss ≥300 ml and number of patients with blood transfusion were (170±41)minutes, 8, 7 in the AR group and (148±35)minutes, 19, 18 in the NR group, respectively, with statistically significant differences between the 2 groups (P<0.05). (2) The 1-year, 2-year and 3-year overall survival rate were 85.7%, 68.6%, 57.1% in the AR group and 79.6%, 53.1%, 42.9% in the NR group, respectively. The 1-year, 2-year and 3-year progression-free survival rate were 80.0%, 62.9%, 51.4% in the AR group and 71.4%, 49.0%, 38.8%, in the NR group, respectively. There were statistically significant differences between the 2 groups both in the overall survival rate and the progression-free survival rate (P<0.05). (3) Prognostic factors analysis of HCC patients with MVI: result of univariate analysis showed that maximum diameter of tumor and surgical procedures were relative factors affecting overall survival and progression-free survival of HCC patients with MVI, AFP level was relative factors affecting progression-free survival of HCC patients with MVI, with statistically significant differences (P<0.05). Result of multivariate analysis showed that maximum diameter of tumor between 3.0 and 5.0 cm and non-anatomic liver resection were independent factors affecting poor overall survival and progression-free survival of HCC patients with MVI, and AFP≥20 μg/L and total bilirubin ≥20 μmol/L were independent factors affecting poor progression-free survival of HCC patients with MVI, with a statistically significant differences (P< 0.05). Conclusion: Anatomic hepatectomy for patients with single small hepatocellular carcinoma with microvascular invasion has better clinical efficacy and safety.

Abstract
Objective: To evaluate the clinicopathological characteristics of foot and ankle soft tissue and bone tumor, and to analyze the prognosis and the related factors of malignant tumors in this site. Methods: 74 patients with soft tissue and bone tumors of foot and ankle from January 2006 to February 2017 were retrospectively analyzed. The clinicopathological characteristics, the treatment and survival status of malignant tumors were followed up, and the clinical and therapeutic factors related to prognosis were analyzed. Results: Of the 74 patients, 34 were males and 40 were females. The male to female ratio was 1∶1.18; the age ranged from 12 to 64 years and the median age was 42 years. Tumors located in forefoot of 22 cases, 22 in midfoot, 10 in hind foot, 14 in ankle joint and 6 in multiple sites. 14 cases were bone tumors, including 7 benign and 7 malignant, and 60 cases were soft tissue tumors, including 14 benign and 46 malignant. The most common malignant soft tissue tumors were synovial sarcomas (13 cases), and the most common benign soft tissue tumors were hemangiomas (4 cases). 44 cases of malignant tumors underwent surgery were followed up, of which were 7 bone and 37 soft tissue malignant tumors. Limb salvage surgeries were performed in 33 cases and amputation in 11 cases. The median follow-up time was 69.8 months, and the median survival time was 40.7 months. The 1-year, 3-year and 5-year survival rate of soft tissue malignant tumors was 88.0%, 73.0%, and 63.0%, respectively. The 1-year, 3-year and 5-year survival rate of bone malignant tumors was 86.0%, 57.0% and 57.0%, respectively. Univariate analysis showed that the prognostic factors affecting 5-year survival rate were tumor size and adjuvant therapy (P<0.05). Patient's gender, age, tumor location, histological type and surgical procedure had no effect on overall survival(P>0.05). Multivariate analysis showed that tumor size was an independent prognostic factor (RR=7.262, P=0.005). Conclusions: Forefoot and midfoot are more common in foot and ankle soft tissue and bone tumors. Synovial sarcoma is the most common diagnosis in malignant soft tissue tumors, and hemangioma is the most common diagnosis in benign soft tissue tumors. The prognostic factor of malignant soft tissue and bone tumors in foot and ankle is tumor size. Patients with the tumor size of 5 cm or more have a worse prognosis.

Abstract
Objective: To evaluate the association of the ultrasonographic optic nerve sheath diameter (ONSD) and intracranial pressure (ICP), and the feasibility of ultrasonographic ONSD in predicting high ICP. Methods: A prospective study. The outpatients who planned to measure ICP by lumbar puncture in Department of Neurology, Xuanwu Hospital, Capital Medical University were selected from January 2011 to May 2012. All the retrobulbar ONSD measurement with B-scan ultrasound was performed just before lumbar puncture. When high ICP was defined as ICP more than 200 mmH2O(1 mmH2O=0.009 8 kPa), the participants were divided into the high ICP group and the normal ICP group. The Pearson correlation coefficient analysis was used to analyze the correlation between ICP and postbulbar ONSD measurements. The difference in ONSD was compared between the high ICP and normal ICP groups with the t test. The receiver operating characteristic (ROC) curve was used to calculate the cutoff value of mean ONSD and evaluate the sensitivity and specificity of the method. Results: A total of 130 participants were involved in this study. There were 71 males and 59 females, aged (38±14) years.The mean ICP was (209.84±79.99) mmH2O. The mean ONSD was (5.68±0.78) mm in the right eyes, (5.78±0.78) mm in the left eyes, and (5.73±0.71) mm in both eyes. The ICP had a significant correlation with ONSD in the right eyes (r=0.54, P<0.001), ONSD in the left eyes (r=0.56, P<0.001) and ONSD in both eyes (r=0.60, P<0.001), but no correlation with age (r=-0.14, P=0.114) and gender (r=0.20, P=0.817). The ONSD in the high ICP group (n=65) was (6.11±0.66) mm, (6.22±0.56) mm and (6.17±0.50) mm in the right eyes, left eyes, and both eyes, respectively. Compared with the ONSD in the normal ICP group (n=65), which was (5.26±0.64) mm in the right eyes, (5.34±0.72) mm in the left eyes and (5.30±0.62) mm in both eyes, there was a significantly enlarged ONSD in the high ICP group (t=-7.507, -7.778, -8.779, all P<0.001). The ROC analysis showed the ONSD of 5.6 mm was the best cutoff value with a sensitivity of 86% and a specificity of 71% for identifying high ICP. Conclusions: There is a significantly positive correlation between ICP and postbulbar ONSD measured by ultrasound. This non-invasive method may be an alternative approach to predicting the ICP value of patients whose ICP measurement via lumbar puncture is at high risk. However, it can not replace the direct ICP measurement with the invasive method. (Chin J Ophthalmol, 2018, 54: 683-687).

Abstract
Objective: To improve the accuracy of diagnosis and to reduce the misdiagnosis rate of nasopharyngeal carcinoma by analyzing the characteristics of such masses. Methods: Clinical data from 55 patients with suspicion of nasopharyngeal carcinoma diagnosed and treated between March 2016 and September 2017 were analyzed. All patients were followed up regularly. Results: With following-up of 12 to 25 months, 6 (10.9%) of 55 cases were identified as nasopharyngeal malignant tumors, including 4 cases of nasopharyngeal carcinoma and 2 cases of lymphoma, and 49 cases (89.1%) were diagnosed with nasopharyngeal benign masses, including 29 (59.2%) cases for nasopharyngeal lymphoid proliferation, 15 (30.6%) for adenoid hypertrophy, 2 (4.1%) for nasopharyngeal cyst, 1 (2.0%) for polyp, 1 for papilloma and 1 for nasopharyngeal pharyngeal cyst. Small nasopharyngeal malignant tumor and masses with benign hyperplasia showed the overlap of images on the enhanced MRI/CT and Fibro-nasopharyngoscopy, but all 6 patients with nasopharyngeal malignant tumors presented with moderately enhanced multiple enlarged lymph nodes. Conclusions: Fibro-nasopharyngoscopy and enhanced MRI/CT have some value on evaluation of nasopharyngeal masses, but biopsy is a golden standard for diagnosis. Follow-up is necessary for the patients with negative biopsy and benign nasopharyngeal hyperplasia indicated by fibro-nasopharyngoscopy and enhanced MRI/CT.

Abstract
OBJECTIVE To explore mechanism of health beliefs by application of health belief model (HBM) and structural equation modeling (SEM) with regard to recreational physical activity (PA), to identify the differences of among population with high risk of chronic diseases and healthy people, and to provide the specific interventions of recreational physical activity and reference for health relevant policy-making in the future. METHODS A total of 2 736 residents with high risk of chronic diseases and 1 514 healthy people were involved. A questionnaire survey, physical examination and biochemical examination were conducted. The questionnaire based on HBM had acceptable validity and reliability. The proposed model based on the total sample size of the two groups was developed using the structural equation modeling and multi-comparison in the ways of appearance and parameters were also validated. RESULTS The median amount of recreational (PA) among population with high risk of chronic diseases and healthy people were 0.0 thousand-step equivalent with quartile of (0.0, 4.6) and 0.0 thousand-step equivalent with quartile of (0.0, 4.0) respectively. The results of SEM suggested that the direct effects of perceived objective barriers (β=-0.245), perceived subjective barriers (β=-0.057), cues to action (β=-0.043) and self-efficacy (β=0.117) on recreational (PA) were significant. Self-efficacy was the most important mediator. The multi-group comparisons indicated that the models of the two groups had the same appearance but the parameters between them were significant (δ χ2=27.4, P<0.05). The multi-group structural equation model (MSEM) indicated that two paths from cues to action and from perceived subjective barriers to recreational (PA) were not statistically significant among the population with high-risk of chronic diseases. In the two groups, one path coefficient from perceived objective barriers to subjective barriers (P=0.007) was statistically significant (P<0.05). CONCLUSION The recreational (PA) levels of both groups were lower. Health beliefs on recreational (PA) of the two groups played different roles and some paths were also different. Therefore, specific interventions and strategies should be developed for different people. For residents with high risk of chronic diseases, much more attention should be paid to reduce the objective and subjective barriers of recreational physical activity and to improve self-efficacy so as to delay or prevent the occurrence of chronic diseases and then to improve the quality of life of this kind of population.

Abstract
Objective: To compare the safety of continued warfarin therapy and bridging anticoagulation therapy during hospital stay in patients undergoing percutaneous coronary intervention (PCI). Methods: We retrospectively analyzed patients on warfarin therapy referred for PCI in Beijing Anzhen Hospital from January 2008 to December 2016. The patients were divided into continued warfarin therapy (n=195) or bridging anticoagulation therapy (n=311) groups. After Propensity Score Matching, data from matched patients (n=123 in each group) were analyzed. Bleeding complications and major adverse cardiac events including death, myocardial infarction, target vessel revascularization, and stent thrombosis were assessed. Results: There were no significant difference in the rate of death (2.4%(3/123) vs. 1.6%(2/123),P=0.54), acute myocardial infarction (4.1%(5/123) vs. 4.9%(6/123), P=0.78),re-revascularization (0.8%(1/123) vs. 1.6%(2/123),P=0.16), stent thrombosis (1.6%(2/123) vs. 1.6%(2/123),P=1.00) and stroke between the two groups. Prevalence of minor bleeding complications was significantly higher in the bridging therapy group (15.4%(19/123) vs. 9.8%(12/123),P=0.01). Rate of access-site complications (hematoma:4.1%(5/123) vs. 2.4%(3/123),P=0.20; pseudoaneurysm:2.4%(3/123) vs. 2.4%(3/123),P=1.00; arteriovenous fistula:0.8%(1/123) vs. 1.6%(2/123),P=0.09; and retroperitoneal hematoma:0(0/123) vs. 0.8%(1/123),P=0.23) were similar between the two groups. Conclusion: For patients receiving chronic warfarin therapy, the uninterrupted oral anticoagulant treatment is as safe as bridging therapy in PCI patients.

Abstract
Objective: To evaluate the clinical value of preoperative (18)F-Fludeoxyglucose ((18)F-FDG PET-CT) in lymphatic metastasis diagnosis of cutaneous melanoma on extremities and trunk. Methods: 112 patients with cutaneous melanoma pathologically of extremities and trunk from January 2006 to December 2016, who received (18)F-FDG PET-CT examination preoperatively, were retrospectively reviewed. The correlations between the maximal diameters of lymph nodes, the maximal standard uptake value (SUV) and the diagnostic impression grades of PET-CT examination, and the final pathological diagnosis were analyzed. The correlations between Breslow thickness of primary lesions and the diagnostic impression of PET-CT examination were also analyzed. All the above were analyzed with Receiver Operating Characteristic (ROC) curve to get the cut-off value. Based on the final results of pathological diagnosis of lymph nodes as the golden standard, the statistically significant indicators of ROC curve analysis were used to evaluate the diagnostic effect, as well as to calculate the sensitivity, specificity and accuracy. With gender, age, maximal diameter of lymph nodes, maximal SUV, diagnosis impressions, and Breslow thickness as the independent variables and pathological diagnosis results of lymph nodes as the dependent variable, two-class stepwise Logistic regression analysis was used to determine the independence of diagnostic indicators. ROC curve analysis and log rank test were used to analyze the relationship between Breslow thickness and patient survival. Results: To evaluate melanoma patients' lymph node status, the results of ROC curve analysis showed that the area under the curve of lymph node maximal diameter, maximal SUV, diagnosis impression of PET-CT examinations were 0.789, 0.786 and 0.816, respectively (all P<0.05). The cut-off values were 0.85 cm, 1.45 and 2.5, respectively. The sensitivity of the cut-off values to determine the status of lymph nodes in melanoma patients were 71.4%, 64.9% and 72.1% respectively, and the specificities were 85.2%, 88.7% and 87.0% respectively. Multivariate Logistic regression analysis showed that PET-CT diagnosis impressions had independent diagnostic significance for the lymph node status of melanoma patients (OR=11.296, 95%CI: 2.550~50.033). The area under the curve of Breslow thickness evaluating PET-CT diagnostic impression is 0.664 (P=0.042) and the cut-off value was 4.25 mm. The survival rate of the patients with Breslow thickness ≥ 4.25 mm was lower than that in the group <4.25 mm (P=0.006). Conclusions: (18)F-FDG PET-CT can help to evaluate metastases and make treatment decisions for cutaneous melanoma of extremities and trunk, especially for patients whose primary lesion's Breslow thickness has reached more than 4.25 mm. For the patients whose maximal SUV of regional lymph node is higher than 1.45 and short diameter of the largest lymph node is larger than 0.85cm, the possibility of metastases should be considered.

Abstract
OBJECTIVES The changes of CSF flow dynamics in idiopathic normal pressure hydrocephalus (iNPH) are not fully elucidated. Most previous studies took the whole cardiac cycle as a unit. In this work, it is divided into systole and diastole phase and compared between iNPH patients and normal elderly and paid special attention to the change of netflow direction. MATERIALS AND METHODS Twenty iNPH patients according to international guideline and twenty healthy volunteers were included in this study and examined by MRI. Three categories of CSF flow parameters were measured: peak velocity (Vpeak ), stroke volume (SV), and minute flow volume (MinV) covering the whole cycle; peak velocity (Vpeak-s , Vpeak-d ) and flow volume (Vols , Vold ) of the systole and diastole, respectively; net flow. Evans index (EI) was also measured and compared statistically between the two groups. RESULTS EI, Vpeak , SV, MinV, Vols , Vold , and Vpeak-d significantly increased in iNPH group (P<0.05). Vpeak-s of the two groups were not significantly different (P>0.05). The net flow of 16 iNPH patients (16/20) was in the caudo-cranial direction, while 15 volunteers (15/20) were in the opposite direction, which showed statistically significant differences (P=.001). CONCLUSIONS INPH patients present hyperdynamic flow with increased velocity and volume both in systole and diastole phase. Degree of rising in diastole phase exceeds that of systole phase. The resulting reversal of netflow direction may play a key role in the occurrence of ventriculomegaly in iNPH patients.

Abstract
Chronic hepatitis B (CHB) is one of the major public health challenges in the world. Due to a strong interplay between specific T-cell immunity and elimination of hepatitis B virus (HBV), efforts to develop novel immunotherapeutics are gaining attention. TG1050, a novel immunotherapy, has shown efficacy in an animal study. To support the clinical development of TG1050 in China, specific immunity to the fusion antigens of TG1050 was assessed in Chinese patients. One hundred and thirty subjects were divided into three groups as CHB patients, HBV spontaneous resolvers, and CHB patients with HBsAg loss after antiviral treatment. HBV-specific T-cell responses to pools of HBV Core or Polymerase genotype D peptides included in TG1050 were evaluated. HBV Core- or Polymerase-specific cells were detected in peripheral blood mononuclear cells (PBMCs) from the different cohorts. The frequencies and intensities of HBV Core-specific immune responses were significantly lower in CHB patients than in HBsAg loss subjects. In CHB patients, a dominant pool derived from Polymerase (Pol1) was the most immunogenic. CHB patients with low viral loads (<106 IU/mL) were more likely to have a positive response specific to the Core peptide pool. Overall, genotype D-derived peptides included in TG1050 could raise broad and functional T-cell responses in PBMCs from Chinese CHB patients infected with genotype B/C isolates. Core-specific immunogenic domains appeared as "hot spots" with the capacity to differentiate between CHB vs HBsAg loss subjects. These observations support the extended application and associated immune monitoring of TG1050 in China.

Abstract
Adaptive immunity, especially the cellular immunity mediated by T lymphocytes, plays an important role in the body's fight against hepatitis C virus (HCV) infection. The clearance of HCV requires a strong, sustained, and multi-epitope response from specific T lymphocytes, and the dysfunction of specific T lymphocytes is the major reason for chronic infection. Effective treatment can restore the function of specific T lymphocytes to a certain extent. This article reviews the features and related mechanisms of immune response from specific T lymphocytes when the prognosis of patients with HCV infection is different.

Abstract
Nonalcoholic fatty fiver disease (NAFLD) is one of the most common causes of chronic liver disease in clinical practice. It develops from simple fatty liver, nonalcoholic fatty hepatitis to liver fibrosis which may develop liver cirrhosis and result in hepatocellular carcinoma(HCC) eventually. Although studies show that many cell signaling pathways, genes and cell factors are involved in the progression and development of NAFLD related HCC, the exact mechanism underling the pathogenesis of NAFLD-HCC remains poorly understand. Here in this review, we give a summary of the recent findings at home and abroad that describe the epidemiology and pathogenesis of NAFLD associated HCC.

Abstract
The Head and neck squamous cell carcinoma (HNSCC) is a group of heterogeneous diseases. Patients with HNSCC demonstrate poor prognosis and survival time with standard therapy, especially in patients with advanced HNSCC. Recurrence and metastasis have not yet been effectively controlled. The immune profile in HNSCC, whether caused by carcinogen exposure or human papillomavirus (HPV), showed significantly immunosuppression. With the understanding of the complex interaction between tumor and immune system and immune escape mechanism of HNSCC, new immunotherapies have been generating. This article will summarize the immunological mechanism and immune therapy of HNSCC currently..

Abstract
Objective: To investigate the clinicopathological features and prognosis of malignant peripheral nerve sheath tumors (MPNST). Methods: We retrospectively reviewed the clinical data of MPNST patients who were treated at Cancer Institute & Hospital, Chinese Academy of Medical Science from January 1999 to January 2016. A total of 140 patients with 66 male and 74 female with MPNST were enrolled in the study. The median age was 40 at the time of diagnosis. Survival analysis were estimated by Kaplan-Meier method and Log rank test. Multivariate analysis were estimated by Cox proportional hazards regression model. Results: The median follow-up time was 43.0 months. The 3- and 5-year overall survival (OS) rates were 56.4% and 48.6%, respectively. The 3-year local recurrence (LR) rate and distant metastasis (DM) rates were 42.9% and 49.3%, respectively. Univariate analysis showed that the tumor location, AJCC stage, S-100, radiotherapy and margin status affected 5-year OS rate (all P<0.05). The tumor location, AJCC stage, S-100, Ki-67 staining, margin status, radiotherapy and chemotherapy affected 3-year LR rate (all P<0.05). The tumor location, AJCC stage, S-100, Ki-67 staining and margin status affected 3-year DM rate (all P<0.05). Multivariate analysis showed that the tumor location, AJCC stage, S-100 were independent factors for 5-year OS rate (all P<0.05). The tumor location, Ki-67 staining and chemotherapy were independent factors for LR (all P<0.05) while the AJCC stage, margin status and Ki-67 staining were independent factors for DM (all P<0.05). Conclusions: MPSNT is an aggressive tumor with poor prognosis. Multiple factors were identified in this study. Patients with the tumor located at head and neck, advanced AJCC stage and negative S-100 usually have a low 5-year overall survival rate. Patients with the tumor located at head and neck, Ki-67 staining ≥ 20% and without chemotherapy had a higher tendency of local recurrence. Poor prognosis factors for DM were advanced AJCC stage, positive margin and Ki-67 staining ≥ 20%.

Abstract
Chinese cabbage is an important cruciferous vegetable in China. The differences in the morphology and other characteristics of the different varieties of Chinese cabbage are generally caused by their different genes. Using the simple sequence repeat (SSR) DNA molecular markers is an effective way to identify different genotypes. The identification of a genetic relationship is a key point in the breeding process, and it plays an important role in guiding parent selection and breeding of high-yield varieties. Moreover, the establishment of genomic fingerprints is significant for plant variety protection. Three to five SSR sites were selected from each of the 10 Chinese cabbage chromosomes on the basis of the abundance of SSR loci on them. According to the differences in the SSR polymorphic bands, a genomic fingerprint comprising 36 different loci was established in the 20 main inbred lines of Chinese cabbage, and this fingerprint was converted digitally into a molecular ID with 36 numbers based on the 36 SSR sites. The utility of this core set SSRs was demonstrated in 20 main inbred lines of Chinese cabbage, which could be placed into six clusters that were largely consistent with previous classification based on morphology data. Moreover, the molecular ID of an F1 hybrid can be deduced from its parents molecular IDs, and its purity can be determined by selecting one or two SSR loci from the 36 different loci.

Abstract
Objective: To prepare a rabbit monoclonal antibody GCET2 and to investigate its diagnostic value in the workup of diffuse large B-cell lymphoma (DLBCL). Methods: GCET2 rabbit monoclonal antibody was developed by using RabMAb® technology, and its specificity was confirmed by ELISA, Western blot, immunohistochemistry (IHC) and flow cytometry. A panel of immunomarkers including GCET2, CD10, bcl-6, MUM1, GCET1, FOXP1, Ki-67 and CMYC was evaluated in 81 cases of DLBCLs, 5 cases of follicular lymphomas (FL) and 2 cases of Burkitt's lymphomas. Results: Rabbit monoclonal GCET2 antibody (clone EP316) was developed with specificity for normal germinal center B-cells (GCB) and GCB origined lymphomas. In 81 cases of DLBCL, the positive rate of GCET2 was 43.2%(35/81), which was significantly higher than that of other germinal center markers. Moreover, among 81 DLBCLs, the proportions of high CMYC expression in GCET2 negative and positive groups were 15.2% (7/46) and 2.8% (1/35), respectively. Conclusion: GCET2 is a sensitive immunohistochemical marker for GCB derived lymphomas. Combined with other biomarkers, it may improve the diagnostic sensitivity of GCB-DLBCL.

However, it is a great challenge to quantitatively compare the topological structural variations of modules (allosteric modules [AMs]) under different situations. A total of 23, 42, and 15 coexpression modules were identified in baicalin (BA), jasminoidin (JA), and ursodeoxycholic acid (UA) in a global anti‐ischemic mice network, respectively. Then, we integrated the methods of module‐based consensus ratio (MCR) and modified Zsummary module statistic to validate 12 BA, 22 JA, and 8 UA on‐modules based on comparing with vehicle. The MCRs for pairwise comparisons were 1.55% (BA vs. JA), 1.45% (BA vs. UA), and 1.27% (JA vs. UA), respectively. Five conserved allosteric modules (CAMs) and 17 unique allosteric modules (UAMs) were identified among these groups. In conclusion, module‐centric analysis may provide us a unique approach to understand multiple pharmacological mechanisms associated with differential phenotypes in the era of modular pharmacology.

Abstract
OBJECTIVE To analyze the clinical characteristics of multiple primary cancers (MPC) associated with head and neck. METHODS A total of 71 patients with MPC associated with head and neck treated from January 2008 to November 2015 were included in the retrospective study, of them 20 patients were synchronous MPC and 51 patients were metachronous MPC; 45 (63.4%) patients were field cancerization of head neck (FCHN) and 26 (36.6%) patients were non-field cancerization of head neck (NFCHN). For the synchronous MPC patients with an interval of 0 month, the lesion sites of FCHN were treated with combined chemotherapy and radiotherapy, the site of severe lesion of NFCHN received firstly a standard treatment. Other types of MPC were treated according to international guide lines or experts consensus. RESULTS With the mean follow-up of 63.4 months, the 3-year and 5-year overall survival (OS) were 84.6% and 75.7% respectively. The 3-year and 5-year OS were 56.4% and 37.6% respectively in patients with synchronous MPC, and were 92.2% and 84.2% respectively in patients with metachronous MPC. There was significant difference in the OS between patients with metachronous MPC and patients with synchronous MPC (P=0.0002). The 3-year and 5-year OS were 85.7% and 77.9% respectively in patients with FCHN, and were 82.9% and 72.8% respectively in patients with NFCHN, with no significant difference between the two groups (P=0.297). CONCLUSION With correct diagnosis and effective curative treatment, some of patients with MPC can get long-term survival, showing the better prognosis in metachronous MPC compared to synchronous MPC.

Abstract
BACKGROUND Tuberculous meningitis (TBM) is the most severe form of tuberculosis. Microbiological confirmation is rare and treatment is often delayed. Early diagnosis and immediate initiation of treatment are essential for effective TBM control. A systematic review was performed in this study to assess the diagnostic accuracy of detecting antibodies against Mycobacterium tuberculosis in the cerebrospinal fluid (CSF), according to standard methods. Test performance was summarized using a bivariate random-effects meta-analysis. METHODS Studies were identified by a search of the literature, up to July 25, 2015, in the EMBASE and MEDLINE databases via Ovid SP and PubMed. The Cochrane Library was also searched for original, peer-reviewed molecular epidemiology studies that reported the diagnosis of TBM based on antibody detection in the CSF. RESULTS Thirty-six articles (58 studies) were identified. The sensitivity of antibody detection was 0.75 (95% confidence interval (CI) 0.66-0.82), specificity was 0.98 (95% CI 0.96-0.99), and the area under the receiver operating characteristic curve (AUROC) was 0.97 (95% CI 0.95-0.98). By subgroup analysis, the detection of anti-M37Ra was the highest (AUROC 0.99, 95% CI 0.98-1.00), followed by anti-antigen 5 (AUROC 0.99, 95% CI 0.97-0.99) and anti-M37Rv (AUROC 0.97, 95% CI 0.95-0.98). CONCLUSIONS For the early diagnosis of TBM based on antibodies in the CSF, the detection of anti-M37Ra, anti-antigen 5, or anti-M37Rv provides the greatest sensitivity and specificity.
