Abstract
Recently, the deep learning methods have received more attention in histopathological image analysis. However, the traditional deep learning methods assume that training data and test data have the same distributions, which causes certain limitations in real-world histopathological applications. However, it is costly to recollect a large amount of labeled histology data to train a new neural network for each specified image acquisition procedure even for similar tasks. In this paper, an unsupervised domain adaptation is introduced into a typical deep convolutional neural network (CNN) model to mitigate the repeating of the labels. The unsupervised domain adaptation is implemented by adding two regularisation terms, namely the feature-based adaptation and entropy minimisation, to the object function of a widely used CNN model called the AlexNet. Three independent public epithelium-stroma datasets were used to verify the proposed method. The experimental results have demonstrated that in the epithelium-stroma classification, the proposed method can achieve better performance than the commonly used deep learning methods and some existing deep domain adaptation methods. Therefore, the proposed method can be considered as a better option for the real-world applications of histopathological image analysis because there is no requirement for recollection of large-scale labeled data for every specified domain.

Abstract
AIM To explore the role of computed tomography (CT) texture analysis in predicting pathologic stage of gastric cancers. MATERIALS AND METHODS Preoperative enhanced CT images of 153 patients (112 men, 41 women) with gastric cancers were reviewed retrospectively. Regions of interest (ROIs) were manually drawn along the margin of the lesion on the section where it appeared largest on the arterial and venous CT images, which yielded texture parameters, including mean, maximum frequency, mode, skewness, kurtosis, and entropy. Correlations between texture parameters and pathological stage were analysed with Spearman's correlation test. The diagnostic performance of CT texture parameters in differentiating different stages was evaluated using receiver operating characteristic (ROC) analysis. RESULTS Maximum frequency in the arterial phase and mean, maximum frequency, mode in the venous phase correlated positively with T stage, N stage, and overall stage (all p<0.05) of gastric cancer. Entropy in the venous phase also correlated positively with N stage (p=0.009) and overall stage (p=0.032). Skewness in the arterial phase had the highest area under the ROC curve (AUC) of 0.822 in identifying early from advanced gastric cancers. Multivariate analysis identified four parameters, including maximum frequency, skewness, entropy in the venous phase, and differentiation degree from biopsy, for predicting lymph node metastasis of gastric cancer. The multivariate model could distinguish gastric cancers with and without lymph node metastasis with an AUC of 0.892. CONCLUSION Multiple CT texture parameters, especially those in the venous phase, correlated well with pathological stage and hold great potential in predicting lymph node metastasis of gastric cancers.

Abstract
Objective: To understand the prevalence rates of HIV-syphilis and HIV-herpes simplex virus 2 (HSV-2) co-infections and related factors among men having sex with men (MSM) who had visited the voluntary HIV counseling and testing (VCT) clinics in Shanghai, China. Methods: 756 eligible MSM who attended the VCT clinics of Shanghai Municipality and Putuo district during March to August, 2015 were recruited to participate in a cross-sectional survey with questionnaire interview and blood testing for HIV, syphilis and HSV-2. Results: A total of 732 participants completed a valid questionnaire survey. The prevalence rates were 3.3% (24/732) for HIV/Syphilis co-infection, 1.9% (14/732) for HIV/HSV-2 co-infection, and 0.7% (5/732) for HIV/Syphilis/HSV-2 co-infection, respectively. HIV prevalence appeared significantly higher among syphilis-infected participants (45.3%, 24/53) than those without Syphilis (7.2%, 61/679) (χ(2)=63.11, P<0.001), and was also significantly higher among HSV-2 infected participants (34.1%, 14/41) than those without the HSV-2 infection (10.3%, 71/691) (χ(2)=21.49, P<0.001). Results from the Multivariate regression analysis indicated that participants who were migrants (OR=3.50, 95%CI: 1.01-12.17), having had middle school or lower levels of education (OR=4.46, 95%CI: 1.54-12.87) or ever used illicit drugs (OR=4.25, 95%CI: 1.67-10.82, P=0.002) were under possible risks on HIV and Syphilis co-infection. Those participants who had high middle school or lower levels of education (OR=6.87, 95%CI: 1.86-25.42; OR=9.82, 95%CI: 2.25-42.85) were under risk on HIV and HSV-2 co-infection. Conclusion: HIV/Syphilis and HIV/HSV-2 co-infection were seen among MSM who attended the VCT clinics in Shanghai that called for special attention, especially on migrants, those with low education or illicit drug users.

Abstract
Poly-ε-L-lysine is a natural homo-polyamide of L-lysine with excellent antimicrobial properties, which can be used as a novel preservative and has a wide range of applications. In this paper, the fermentation medium for ε-PL production by Streptomyces diastatochromogenes 6#-7 was optimized by Response Surface Methodology. The results of Plackett-Burman design showed that glucose, yeast extract and (NH4 )2 SO4 were the major influencing factors in ε-PL production of S. diastatochromogenes 6#-7. The optimal concentrations of glucose, yeast extract and (NH4 )2 SO4 were determined to be 60, 7·5 and 7·5 g l-1 according to Box-Behnken experiment and regression analysis, respectively. Under the optimized conditions, the ε-PL yield in shake-flask fermentation was 0·948 ± 0·030 g l-1 , which was in good agreement with the predicted value of 0·970 g l-1 . The yield was improved by 43·1% from that with the initial medium. In 5 l jar-fermenter the ε-PL yield reached 25·5 g l-1 , which was increased by 56·4% from the original medium. In addition, the fermentation time was reduced from 174 to 120 h. SIGNIFICANCE AND IMPACT OF THE STUDY Medium optimization is a very practical and valuable tool for fermentation industry to improve product yield and minimize by-products as well as reduce overall manufacturing costs. The response surface methodology is not new, but it is still a very effective method in medium optimization research. This study used ε-polylysine fermentation as an example to demonstrate how the product yield can be significantly increased by medium optimization through surface response methodology. Similar approach can be used in other microbial fermentations such as in pharmaceutical, food, agricultural and energy industries. As an example, ε-polylysine is one of a few newly approved natural food-grade antimicrobials for food and beverages preservations. Yield improvement is economically beneficial to not only ε-polylysine manufacturers but also to their users and consumers due to lower costs and price.

Abstract
Electrical control of structural and physical properties is a long-sought, but elusive goal of contemporary science and technology. We demonstrate that a combination of strong spin-orbit interactions (SOI) and a canted antiferromagnetic Mott state is sufficient to attain that goal. The antiferromagnetic insulator Sr_{2}IrO_{4} provides a model system in which strong SOI lock canted Ir magnetic moments to IrO_{6} octahedra, causing them to rigidly rotate together. A novel coupling between an applied electrical current and the canting angle reduces the Néel temperature and drives a large, nonlinear lattice expansion that closely tracks the magnetization, increases the electron mobility, and precipitates a unique resistive switching effect. Our observations open new avenues for understanding fundamental physics driven by strong SOI in condensed matter, and provide a new paradigm for functional materials and devices.

Abstract
We describe the epidemiology of hepatitis B virus (HBV) infection among women of reproductive age residing in areas of China that are highly endemic for chronic HBV, and provide evidence useful for decision-makers to guide strategies for preventing mother-to-child transmission of HBV, and assess the impact of perinatal transmission PMTCT by projecting HBsAg prevalence trends without interventions. We conducted a cross-sectional HBV serological survey of women, 15-49 years of age, residing in Fujian, Guangdong, Guangxi and Hainan provinces. Demographic and other subject-level data were collected in face-to-face interviews, after which we obtain blood specimens. Specimens were tested for HBV sero-markers by ELISA (Beijing Wantai Biological Pharmacy), and HBV DNA was tested with PCR (Hunan Sansure Biotech). Weighted HBsAg and HBV (either HBsAg+ or anti-HBc+ indicating either present or past infection) prevalences were 11.82% and 57.16%, respectively. Among the HBsAg-positive women, 27% were also HBeAg positive. The proportion of individuals with HBV DNA loads >105 IU/mL declined with increasing age. Among HBsAg-negative women, 0.9% had occult HBV infection. The prevalence of chronic HBV infection among reproductive women in these highly endemic provinces is high, posing a threat to maternal health and risk of mother-to-child transmission. Prevention of mother-to-child transmission remains critically important.

Abstract
AIMS In this study, we investigated the preventive properties of the supernatant of Lactobacillus helveticus NS8-fermented milk (NS8-FS) against UV light-induced skin oxidative damage and hyperpigmentation. METHODS AND RESULTS NS8-FS exhibited significant radical scavenging activity in tests with ABST+ and DPPH scavenging methods, and as well strongly inhibited 3-morpholinosydnonimine (Sin-1)-induced ROS generation in HaCat keratinocytes. Unexpectedly, NS8-FS was found to inhibit melanin production in B16F10 melanoma cells and to exhibit inhibitory effects both to the enzymatic activity of tyrosinase (TYR) and the expression of proteins required for melanin synthesis. In SKH-1 hairless mice, topical application of NS8-FS alleviated UVB-induced skin photodamage, including the improvement of the appearance of epidermal thickness, transepidennal water loss and lipid peroxidation levels. In the tanning guinea pig model, the whitening effect of NS8-FS was demonstrated using Masson-Fontana staining and TYR staining. Furthermore, NS8-FS was shown to stimulate the nuclear translocation and activation of the Nrf2 protein, along with recovery of antioxidant enzyme activities. CONCLUSION NS8-FS exhibits the protective capacities against UV light-induced skin oxidative damage and hyperpigmentation. SIGNIFICANCE AND IMPACT OF THE STUDY Our findings indicate the potential of cell-free fermented products of lactic acid bacteria in topical photoprotection.

Abstract
Objective: To analyze the epidemiological characteristics of hepatitis A cases in China from 2004 to 2015. Methods: Data of hepatitis A were reported through national notifiable disease information reporting system, which covered the 31 provinces (Hong Kong, Macau and Taiwan excluded). The inclusion criteria was: date of illness onset was between January 1(st) 2004 and December 31(st) 2015, the status of reported card was confirmed, the case was classified as laboratory confirmed or clinical diagnosed, the disease was Hepatitis A. The information such as sex, date of birth, date of illness onset, place of residence was collected. The data was divided into three phases, 2004-2007, 2008-2011, 2012-2015, which represented the phase before expanded program on immunization (EPI), first 4 years after EPI, second 4 years after EPI. Results: From 2004 to 2015, there were totally 574 697 hepatitis A cases in China, the mean annual incidence was 3.62/100 000. The risk ratio of hepatitis A in 2015 was 0.23 when compared with 2004. Sichuan, Xinjiang and Yunnan contributed to 27.27% of the total cases in China. In 2012-2015, the incidence of western (3.46/100 000) region was significantly higher than that in central (1.21/100 000) and eastern (1.08/100 000) regions. From 2004-2015, number of cases in each age group declined greatly, with number of cases declining from 43 711 to 5 938 in the age group of 5-9 years, from 29 722 to 3 438 in 10-14, from 23 212 to 3 646 in 15-19. The number of cases declined from 24 079 to 10 304 in the age group of 0-4 (declined by 57.21%), but in 2012-2015, the incidence of 0-4 age group was still the highest, with 77.72% cases in Xinjiang and Sichuan. Famers, students and scattered children accounted for 69.95% of total cases, with student cases declined from 24.08% (2004-2007) to 8.67% (2012-2015). Conclusion: The incidence of hepatitis A in China is decreasing year by year, the risk has been decreasing to a relatively low level. However, in western regions and children under age five, the risk is still high. Precision intervention is needed for further prevention and control of hepatitis A.

Objective: To evaluate the effect of hepatitis B prevention and control by comparative analysis on the results of HBsAg, anti-HBs and anti-HBc prevalence from national hepatitis B seroepidemiological surveys in 1992 and 2014 in different epidemic regions of China. Methods: Data was from the national seroepidemiological surveys of hepatitis B conducted in 1992 and 2014. The survey in 1992 was conducted in 145 disease surveillance points of 30 provinces (excluding Hong Kong, Macao Special Administrative Region and Taiwan province) in China. The survey in 2016 was conducted in 160 disease surveillance points of 31 provinces (excluding Hong Kong, Macao Special Administrative Region and Taiwan province) in China. In the two surveys, face-to-face interviews with the subject by door to door or on the investigation site were conducted by trained staff using standard questionnaires to obtain basic information including birth date, gender, ethnicity, resident place and so on. And then 5 ml venous blood was collected to test the sero-markers of HBsAg, anti-HBs and anti-HBc. We analyzed unweighted point prevalence and 95% CI of HBsAg, anti-HBs and anti-HBc in 1992 which had no design weighting, and analyzed weighted point prevalence and 95%CI of HBsAg, anti-HBs and anti-HBc in 2014 which had design weighting. Results: 34 291 and 31 713 people aged 1-29 years were involved in 1992 and 2014 national serosurveys of China, respectively. For the people aged 1-29 years, HBsAg prevalence was 2.64% (95%CI: 2.28%-3.06%) in 2014 and decreased by 73.92% as compared with the rate 10.13% (95% CI: 9.81%-10.45%) in 1992. Anti-HBc prevalence was 13.01% (95%CI: 12.09%-14.00%) in 2014 and decreased by 71.61% as compared with the rate 45.84% (95% CI: 45.31%-46.37%) in 1992. Anti-HBs prevalence was 57.79% (95%CI: 56.33%-59.25%) in 2014 and ascended by 127.41% as compared with the rate 25.41% (95% CI: 24.95%-25.87%) in 1992. In high, medium and low epidemic region, for the people who born during 1992-2001 when hepatitis B vaccine was introduced in routine immunization management, HBsAg prevalence was 4.74% (95%CI: 3.79%-5.69%), 1.59% (95%CI: 1.09%-2.10%) and 2.53% (95%CI: 1.66%-3.39%), respectively, and anti-HBs prevalence was 64.25% (95% CI: 62.11%-66.39%), 56.34% (95% CI: 54.50%-58.57%), 54.49% (95%CI: 51.75%-57.23%), respectively, and anti-HBc prevalence was 15.16% (95%CI: 13.56%-16.76%), 11.07% (95%CI: 9.80%-12.33%), 7.61% (95%CI: 6.15%-9.07%), respectively. In high, medium and low epidemic region, for the people who born during 2002-2013 the duration which hepatitis B vaccine was integrated in expanded immunization program born during when HBsAg prevalence was 0.88% (95%CI: 0.66%-1.11%), 0.37% (95%CI: 0.24%-0.49%)and 0.71% (95%CI: 0.48%-0.94%), respectively, and anti-HBs prevalence was 60.74% (95%CI: 59.57%-61.90%), 59.46% (95%CI: 58.44%-60.49%), 52.56% (95% CI: 51.20%-53.92%), respectively, and anti-HBc prevalence was 3.30% (95% CI: 2.87%-3.72%), 1.91% (95%CI: 1.63%-2.20%), 2.25% (95%CI: 1.85%-2.66%), respectively. Conclusion: China had made great achievement in hepatitis B prevention and control. HBsAg prevalence among people aged 1-29 years old in 2014 decreased dramatically as compared with that in 1992. Since hepatitis B vaccine was integrated into expanded immunization program, China reduced HBsAg prevalence to less than 1% among people aged 1-12 years in 2014 in different epidemic region.

Abstract
AIM The cardioprotective effects of sevoflurane postconditioning (SpostC) are eliminated under diabetic conditions, and the underlying mechanism for this phenomenon remains unclear. Many studies have demonstrated that the hypoxia-inducible factor-1 (HIF-1) signalling pathway in the myocardium is impaired under diabetic conditions. This study was to investigate whether deferoxamine (DFO)-induced activation of HIF-1 signalling pathway can restore the cardioprotective effects of SpostC in diabetic rats. METHODS A model of myocardial ischaemia/reperfusion (I/R) injury was induced via ligation of the left anterior descending artery. SpostC was conducted by administering 1.0 MAC sevoflurane. After inducing the I/R injury, the following parameters were measured: myocardial infarct size, cardiac function, myocardial ultrastructure, mitochondrial respiratory function, respiratory chain enzyme activity, rate of reactive oxygen species (ROS) generation, and protein expression of HIF-1α, vascular endothelial growth factor (VEGF), cleaved caspase-3, Bcl-2 and Bax. RESULTS After DFO activated HIF-1 in the impaired myocardium of diabetic rats, SpostC significantly upregulated the protein expression of HIF-1α and its downstream mediator VEGF. This improved myocardial mitochondrial respiratory function and respiratory chain enzyme activity and reduced ROS generation as well as the protein expression of cleaved caspase-3 and Bax. As a result, myocardial infarct size decreased, and cardiac function and mitochondrial ultrastructure improved. CONCLUSION This study demonstrates for the first time that abolishment of the cardioprotective effects of SpostC in diabetic rats is associated with impairment of the HIF-1 signalling pathway and that DFO can activate HIF-1 to restore these cardioprotective effects of SpostC in diabetic rats.

Abstract
AIM To explore the role of texture analysis of computed tomography (CT) images in predicting the malignancy risk of gastrointestinal stromal tumours (GISTs). MATERIALS AND METHODS Seventy-eight patients with histopathologically confirmed GISTs underwent preoperative CT. Texture analysis was performed on unenhanced and contrast-enhanced CT images, respectively. Fourteen CT texture parameters were obtained and compared among GISTs at different malignancy risks with one-way analysis of variance or independent-samples Kruskal-Wallis test. Correlations between CT texture parameters and malignancy risk were analysed with Spearman's correlation test. Diagnostic performance of CT texture parameters in differentiating GISTs at low/very low malignancy risk was tested with receiver operating characteristic (ROC) analysis. RESULTS Three parameters on unenhanced images (r=-0.268-0.506), four parameters on arterial phase (r=-0.365-0.508), and six parameters on venous phase (r=-0.343-0.481) imaging correlated significantly with malignancy risk of GISTs, respectively (all p<0.05). For identifying GISTs at low/very low malignancy risk, three parameters on unenhanced images (area under ROC curve [AUC], 0.676-0.802), four parameters on arterial phase (AUC, 0.637-0.811), and six parameters on venous phase (AUC, 0.636-0.791) imaging showed significant diagnostic performance, respectively (all p<0.05), especially maximum frequency on both unenhanced and contrast-enhanced images (AUC, 0.791-0.811). CONCLUSION Texture analysis of CT images holds great potential to predict the malignancy risk of GISTs preoperatively.

Abstract
During endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), a needle is commonly used with a stylet, although recently the stylet has been omitted. This prospective study aimed to compare the quality of specimens obtained by EBUS-TBNA performed with and without a stylet. Between November 2013 and November 2014, 131 patients with lung cancer underwent EBUS-TBNA, with a total of 148 mediastinal or hilar lymph nodes sampled both with and without an inner-stylet, yielding 296 cytological specimens. Specimens were scored cytologically using five parameters: background blood or clot, amount of cellular material, degree of cellular degeneration, degree of cellular trauma, and retention of appropriate architecture. The procedure with a stylet required significantly longer operation time than without a stylet (14.5±0.8 vs 12.7±1.1 min, P<0.001). Excellent specimens were obtained in 261/296 and 260/296 samples in the procedures with and without a stylet, respectively (P=0.9), while the remaining 35 and 36 samples, respectively, were adequate. The diagnosing and staging of lung cancer using EBUS-TBNA did not differ significantly between the groups. In conclusion, specimen collection by EBUS-TBNA without a stylet is easier and faster than the procedure using a stylet and absence of a stylet did not alter specimen quality or diagnostic accuracy.

Abstract
Objective: To investigate the usefulness and effectiveness of multi-slice spiral computerized tomographic fistulography (MSCTF) in the diagnosis and treatment of congenital fistula of neck. Methods: Thirty-four patients with thyroglossal fistulasor branchial cleft fistulas who were initial treated from July 2008 to August 2015 in Fujian Provincial Hospital were retrospectively analyses. Thirteen males and 21 females patients aging from 3 to 46 years old with a median age of 37 were included. There were thyroglossal fistula in 6 cases, the first branchialcleft fistula in 9 cases, the second branchialcleft fistula in 3 cases, the third branchialcleft fistula in 9 cases, and the fourth branchialcleft fistula in 7 cases. All the patients underwent preopeative MSCTF and the diagnoses were finally confirmed with surgery and histopathology. Multiplanar reconstruction(MPR), maximumintensity projection(MIP)and volume rendering(VR) were completed with AW Volume Share 4.2 image processing software after initial CT scanning.The internal openings, distribution, and neighboring relationship of the fistulas showed by MSCTF were analyzed and the surgical strategies were subsequently made. Results: Except 2 cases, 32 patients had obtained successfully MSCTF image. The presence and location of the fistulas could be showed clearly on MSCTF. Based on the results of MSCTF examination, the surgical planes to treat the fistulas were made. The fistulas in all cases were successfully found and excised. Three cases underwent selective neck dissection. Postoperative infection occurred in 1 case. Unilateral vocal fold paralysis due to surgery recovered 3 months after surgery with follow-up. One case lost follow-up, the remaining 33 cases were followed up for 13-97 months with no the fistula recurrence. Conclusions: MSCTF could provide valuable information and benefit surgical planning by demonstrating the coursesof congenital fistulas of neck in detail.

Abstract
BACKGROUND The BEYOND trial found that the addition of bevacizumab (B) to paclitaxel-carboplatin (PC) chemotherapy provided a significant clinical benefit to Chinese patients with metastatic non-squamous non-small-cell lung cancer (NSCLC). This study aimed to evaluate the cost-effectiveness of adding B to first-line PC induction and continuation maintenance therapy from a Chinese perspective. METHODS A Markov model was developed to estimate the cost and effectiveness of B + PC in the induction and maintenance therapy of patients with metastatic non-squamous NSCLC. Costs were calculated in the Chinese setting, and health outcomes derived from the BEYOND trial were measured as quality-adjusted life years (QALYs). A one-way sensitivity analysis was conducted to explore the impact of various parameters in the study. RESULTS The B + PC treatment was more costly ($112,943.40 versus $32,171.43) and more effective (1.07 QALYs versus 0.80 QALYs) compared with the PC treatment. Adding B to the PC regimen for non-squamous NSCLC results in an incremental cost-effectiveness ratio of $299,155.44 per QALY, which exceeded the accepted societal willingness-to-pay threshold ($23,970.00) for China. In the sensitivity analysis, the duration of progression-free survival (PFS) for the B + PC group, the cost of the PFS state for B + PC group and the price of B were considered the most sensitive factors in the model. CONCLUSIONS The addition of B to first-line PC induction and maintenance therapy was not determined to be a cost-effective strategy for metastatic non-squamous NSCLC in China, even when an assistance program was provided.

Abstract
Cystic echinococcosis (CE) is an anthropozoonotic disease with worldwide distribution and is caused by the cestode Echinococcus granulosus. Anaphylactic shock induced by CE rupture is a serious complication especially in patients with hydatid infections, as the resulting leakage of fluid contains highly toxic endogenous antigen. We aimed to isolate and identify the antigens of specific IgE and IgG1 (sIgE and sIgG1) in E. granulosus cyst fluid (EgCF). Crude antigen for EgCF was prepared from E. granulosus-infected sheep liver. Antigens were separated and identified by one-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis (1D SDS-PAGE), two-dimensional gel electrophoresis (2-DE), and immunoblotting. Results of 1D SDS-PAGE and immunoblotting showed that 40.5 kDa protein was the major antigen of sIgE, and 35.5 kDa protein was the major antigen of sIgG1 in EgCF. Results of 2-DE and immunoblotting showed that main antigens of sIgE in EgCF were four proteins with pI values ranging from 6.5 to 9.0 and a molecular weight of 40.5 kDa. Main antigens of sIgG1 in EgCF were five proteins with pI values ranging from 6.5 to 9.0 and a molecular weight of 35.5 kDa. The antigens identified for sIgE and sIgG1 can provide critical insights into cellular and molecular mechanisms underlying anaphylactic shock induced by CE.

Abstract
Objective: To understand the characteristics of acute hepatitis B inpatients reported by the hepatitis B surveillance pilot points and to estimate the consistency between the diagnosed and reported types of hepatitis B by the clinicians involved. Methods: Data related to acute hepatitis B was from the NNDRS and the characteristics of acute hepatitis B were classified by querying Hospital Information System. We recorded the results based on clinical diagnosis and analyzed the consistency between the reported and diagnosed types that the clinicians made, on hepatitis B. Results: A total of 179 patients were included in this study with all of them as acute hepatitis B reported through NNDRS in 2015-2016. In terms of the durations of disease, among the 179 cases who were HBsAg positive, 32.40% (58/179) of them exceeding 6 months, 2.79% (5/179) within 6 months and 64.80% (116/179) tested the first time or never. Among the 179 cases who claimed having the history of hepatitis, 33.52% (60/179) of them identified as having hepatitis B, 1.12% (2/179) were hepatitis A, C or E, 41.34% (74/179) did not have the signs on hepatitis, while the rest 24.02% (43/179) did not know the situation. Only 79.89% (143/179) of the patients showed the symptoms or signs of hepatitis, but the rest 20.11% (36/179) did not. Among the 179 reported acute hepatitis patients, 67 of them were diagnosed as acute hepatitis B while 112 cases were as non-acute hepatitis B. The consistent rate of acute hepatitis B was 37.43% (67/179). Among the 112 cases that were diagnosed as non-acute hepatitis B, proportions of chronic hepatitis B and cirrhosis were 49.11%(55/112) and 16.07%(18/112) respectively. Conclusion: Consistency between the reported type of acute hepatitis B inpatients and the types diagnosed by clinicians was poor. Our results suggested that clinicians should make the accurate diagnosis at first place and then report to the Network in accordance with the clinical diagnosis classification criterfia, set by the government.

Abstract
Objective: To evaluate the epidemiological characteristics of the children aged 1-4 years without timely birth dose of hepatitis B vaccine (HepB(1)) vaccination. Methods: Based on the data from 160 disease surveillance points in 31 provinces of China, two-stage cluster random sampling was used to select the target population aged 1-4 years. A standard questionnaire was used to collect the information about the birth date, gender, ethnic group, place of birth, HepB immunization history of the children selected. A blood sample (3 ml) was taken from each subject for HBsAg testing. SAS software (Version 9.4) was used in our study. We analyzed the age, gender, ethnic group, area specific distributions of the children aged 1-4 years without timely HepB(1) vaccination and the influencing factors, and the relationship between the HepB(1) vaccination time and HBsAg prevalence rate. Results: A total of 12 587 children aged 1-4 years were analyzed and the non-timely HepB(1) vaccination rate was 10.12%. The place of birth, ethnic group, urban/rural area, eastern/central/western area, age were the main influencing factor of the non-timely HepB(1) vaccination. The non-timely HepB(1) vaccination rate was higher in 3-4 years old children (11.13%) than in 1-2 years old children (8.97%), in rural area (12.05%) than in urban area (8.19%), in western area (13.41%) than in central area (9.27%) and eastern area (7.72%), in minority ethnic group (18.06%) than in Han ethnic group (8.77%) and in children born outside hospital (57.66%) than in children born in hospital (9.27%). The HBsAg prevalence rate among 1-4 years children was 0.31%. The HBsAg prevalence rate of the children with timely HepB(1) vaccination (0.25%) was lower than that of the children without timely HepB(1) vaccination (0.89%). Conclusions: In China, the HBsAg prevalence rate among 1-4 years children with HepB vaccination decreased to <0.5% and the timely HepB(1) vaccination rate reached to 90%. We should strengthen the timely HepB(1) vaccination for the children in minority ethnic groups, in western area, in rural area as well as those born outside hospitals.

Abstract
Oryza longistaminata originates from African wild rice and contains valuable traits conferring tolerance to biotic and abiotic stress. However, interspecific crosses between O. longistaminata and Oryza sativa cultivars are hindered by reproductive barriers. To dissect the mechanism of interspecific hybrid sterility, we developed a near-isogenic line (NIL) using indica variety RD23 as the recipient parent and O. longistaminata as the donor parent. Both pollen and embryo sac semi-sterility were observed in F1 hybrids between RD23 and NIL. Cytological analysis demonstrated that pollen abortion in F1 hybrids occurred at the early bi-nucleate stage due to a failure of the first mitosis in microspores. Partial embryo sacs in the F1 hybrids were defective during the functional megaspore formation stage. Most notably, nearly half of the male or female gametes were aborted in heterozygotes S40iS40l, regardless of their genotypes. Thus, S40 was indicated as a one-locus sporophytic sterility gene controlling both male and female fertility in hybrids between RD23 and O. longistaminata. A population of 16 802 plants derived from the hybrid RD23/NIL-S40 was developed to fine-map S40. Finally, the S40 locus was delimited to an 80-kb region on the short arm of chromosome 1 in terms with reference sequences of cv. 93-11. Eight open reading frames (ORFs) were localized in this region. On the basis of gene expression and genomic sequence analysis, ORF5 and ORF8 were identified as candidate genes for the S40 locus. These results are helpful in cloning the S40 gene and marker-assisted transferring of the corresponding neutral allele in rice breeding programs.

Abstract
Since early 2017, several outbreaks of Seneca Valley virus (SVV) infection have re-emerged in China. We report the identification of novel SVV KS15-01-like strains showing a notable distinction with previous Chinese SVV strains. The determined SVV strains are currently causing new outbreaks in two provinces in China where no SVV infection has been reported previously, implying the increased epidemic regions and potential threat to local pig breeds of SVV in China.

Abstract
Tumor-associated macrophages (TAMs) play an essential role in metastasis. However, what enables TAMs to have a superior capacity to establish pre-metastatic microenvironment in distant organs is unclear. Here we have begun to uncover the effects of cytochrome P450 (CYP) 4A in TAMs on lung pre-metastatic niche formation and metastasis. CYP4A+ TAM infiltration was positively associated with metastasis, pre-metastatic niche formation and poor prognosis in breast cancer patients. The pharmacological inhibition of CYP4A reduced lung pre-metastatic niche formation (evidenced by a decrease in vascular endothelial growth factor receptor 1 positive (VEGFR1+) myeloid cell recruitment and pro-metastatic protein expression) and metastatic burden, accompanied with TAM polarization away from the M2 phenotype in spontaneous metastasis models of 4T1 breast cancer and B16F10 melanoma. Co-implantation of 4T1 cells with CYP4A10high macrophages promoted lung pre-metastatic niche formation and metastasis. Depletion of TAMs disrupted lung pre-metastatic niches and thereby prevented metastasis. Treatment with the CM from CYP4A10high M2 macrophages (M2) increased pre-metastatic niche formation and metastatic burden in the lungs, whereas CYP4A inhibition attenuated these effects. In vitro TAM polarization away from the M2 phenotype induced by CYP4A inhibition decreased VEGFR1+ myeloid cell migration and fibronectin expression, accompanied with downregulation of STAT3 signaling. Conversely, overexpression of CYP4A or exogenous addition of 20-hydroxyeicosatetraenoic acid promoted M2 polarization and cytokine production of macrophages and thereby enhanced migration of VEGFR1+ myeloid cells, which were reversed by siRNA or pharmacological inhibition of STAT3. Importantly, a combined blocking M2 macrophage-derived factors TGF-β, VEGF and SDF-1 abolished VEGFR1+ myeloid cell migration and fibroblast activation induced by CYP4A. In summary, CYP4A in TAMs is crucial for lung pre-metastatic niche formation and metastasis, and may serve as a potential therapeutic target in human cancer.

Abstract
AIM Hyperglycaemia-induced cell injury is a primary cause of cardiovascular complications in patients with diabetes. In vivo studies demonstrated that sevoflurane post-conditioning (SpostC) was cardioprotective against ischaemia/reperfusion injury, which was blocked by hyperglycaemia. This study investigated whether high glucose concentration abrogated SpostC cardioprotection in vitro by advancing mitochondrial fission and whether mitochondrial division inhibitor-1 (Mdivi-1) restored SpostC cardioprotection in cultured primary neonatal rat cardiomyocytes (NCMs). METHODS Primary cultured NCMs in low and high glucose concentrations were subjected to hypoxia/reoxygenation (H/R) injury. SpostC was carried out by adding 2.4% sevoflurane to the cells at the beginning of reoxygenation for 15 min. Cell viability, lactate dehydrogenase (LDH) level, cell death, mitochondrial morphology, mitochondrial membrane potential and mitochondrial permeability transition pore (mPTP) opening level, as well as fission- and fusion-related proteins, were measured after H/R injury. Mdivi-1 treatment was performed 40 min before hypoxia to inhibit DRP1. RESULTS SpostC protected cultured cardiomyocytes by increasing cell viability and reducing the LDH level and cell death following H/R, but high glucose concentration eliminated the cardioprotective effect. High glucose concentration abrogated SpostC cardioprotection via mitochondrial fragmentation (evidenced by decreased mitochondrial interconnectivity and elongation) and facilitation of mPTP opening. Decreased mitochondrial membrane potential was investigated with increased DRP1, FIS1 and MFN2 and decreased MFN1 and OPA1 expressions. Mdivi-1 (100 μmol L-1 ) inhibited excessive mitochondrial fission and restored the cardioprotective effect of SpostC in high glucose conditions. CONCLUSION SpostC-induced cardioprotection against H/R injury was impaired under high glucose concentrations, but the inhibition of excess mitochondrial fission restored these effects.

Abstract
Open aortic aneurysm repair in the setting of bilateral hypogastric aneurysms is technically challenging. We present a novel technique for open surgical repair for bilateral hypogastric aneurysms using the Gore hybrid vascular graft (GVHG; W. L. Gore and Associates Inc, Flagstaff, Arizona). The GVHG is an expanded polytetrafluoroethylene graft with a nitinol stent at 1 end designed for hemodialysis access. The GVHG has been also been used for aortic debranching and treatment of occlusive disease. We describe the first report using GVHG to repair hypogastric aneurysms.

Abstract
OBJECTIVE Recruitment of endothelial progenitor cells (EPCs) to the ischemia has recently been suggested as an important mechanism of neovascularization. Although tissue ischemia can mobilize EPCs from bone marrow, the effects of hypoxia on the migration of EPCs are little known. MATERIALS AND METHODS In this study, migratory function of EPCs was examined by a modified Boyden chamber technique. The expression of CXCR4 was detected by reverse transcription PCR and flow cytometry assay. The protein expressions of ERK1/2 and PI3K/Akt signaling pathways were detected by Western blotting. RESULTS Migration of EPCs in response to the chemokine Stomal-derived factory-1α (SDF-1α) was much enhanced by hypoxia. The enhanced migration can be blocked by the CXCR4 antagonist AMD3100 and the phosphatidylinositol 3-kinase (PI3K) inhibitor LY294002, whereas mitogen-activated protein ERK1/2 kinase inhibitor PD98056 had no significant effect on enhanced migration induced by hypoxia. The expression of CXCR4 markedly increased under hypoxic conditions. A molecular analysis of these events indicated that augmented CXCR4 expression was regulated by the PI3K/Akt signal transduction pathway. CONCLUSIONS These results indicated that exposure of EPCs to hypoxia resulted in a significant up-regulation of CXCR4 expression by PI3K/Akt activation, leading to enhancing chemotaxis behavior.

Abstract
Monema flavescens Walker (Lepidoptera: Limacodidae) is a serious polyphagous defoliator. Using scanning electron microscopy, the external morphology of the antennal sensilla of this pest was examined for a better understanding of the mechanisms of insect-insect and insect-plant chemical communications. The antennae of M. flavescens were filiform in shape, and 11 morphological types of sensilla were found in both sexes. Six types of likely chemosensory sensilla were identified: uniporous sensilla chaetica, multiporous sensilla trichodea, and four types of multiporous sensilla basiconica. The sensilla identified as likely mechanoreceptors included two subtypes of aporous sensilla chaetica, aporous sensilla coeloconica, aporous sensilla styloconica, and Böhm's bristles, whereas the position of the antennae was monitored by Böhm's bristles.

Abstract
AIM To investigate the association between changes in oestradiol and follicle-stimulating hormone levels during the menopausal transition and incident diabetes. METHODS We followed 1407 pre-menopausal women, aged 42-52 years at baseline, who experienced natural menopause, from baseline to the 12th annual follow-up visit in the Study of Women's Health Across the Nation (SWAN). Diabetes was defined based on fasting glucose level, medication use and self-report of physician diagnosis. Cox proportional hazards regression was used to evaluate the associations of incident diabetes with three components of the rate of change in hormones: the intercept (pre-menopausal levels) and two piece-wise slopes representing change during the early and late transition, respectively. RESULTS During 15 years of follow-up, 132 women developed diabetes. After adjusting for potential confounders, a higher oestradiol intercept, but not its rate of change, was borderline significantly associated with lower risk of diabetes [hazard ratio for an interquartile range increase (75.2 pmol/L) 0.53, 95% CI 0.27-1.06]. For follicle-stimulating hormone, a greater rate of increase in the early transition, but not the intercept or late transition, was significantly associated with lower risk of diabetes [hazard ratio for an interquartile range increase (5.9 IU/L/year) 0.31, 95% CI 0.10-0.94]. CONCLUSIONS Lower pre-menopausal oestradiol levels and a slower rate of follicle-stimulating hormone change during the early transition were associated with higher risk of developing diabetes. Given that obesity plays an important role in diabetes risk and in the levels and changes in oestradiol and follicle-stimulating hormone over the menopausal transition, weight control in earlier mid-life is important to prevent future diabetes development.

Abstract
As the only extant school of traditional Chinese medicine(TCM) at the founding of New China, the Guangdong Professional School of TCM was ordered to shut down, thus arousing the contention on whether such schools should be held or not. After the First Congress on Health, the School was existed for the time being, and was incorporated into the Guangdong Training School of TCM due to the reformation of educational system. Actually, the goal of the latter School was to "reform" TCM rather than to cultivate and protect TCM. By 1954, there was a substantial adjustment of the TCM policy, and thus TCM was running into the right path. The original staffs and material resources became the basis for the higher education of TCM in Guangdong Province. The changes of the schools reflect the vicissitudes of TCM education in early New China.

Abstract
OBJECTIVE To analyse and explore the indications and efficacy of liver transplantation for benign liver tumor. METHODS From Jan.2001 to Dec.2014, 6 patients, incluing 3 males and 3 females, with benign liver tumor underwent liver transplantation in our department.There were 2 cases of hepatic epithelioid hemangioendothelioma, 1 case of hepatic cavernous hemangioma, 1 case of liver mesenchymal hamartoma, 1 case of hilar bile duct mucinous cystadenoma, and 1 case of hepatic adenoma. The data of surgical procedure, perioperative complications, postoperative management, and the outcome of follow-up were analyzed. RESULTS Six orthotopic liver transplantation from one living donor and five cadaveric donors were performed. One patient died in the perioperative period, and other patients were discharged with normal liver and kidney function. Within the follow-up time of 22 to 88 months, these patients could live the normal lives with stable graft function and nutritional status. CONCLUSIONS Liver transplantation is the most efficient treatment for unresectable and symptomatic benign lesions, with the favourable outcome.

Abstract
Epithelial-mesenchymal transition (EMT) is a critical event in metastasis of colorectal cancer (CRC). Rho/ROCKs signaling has a pivotal role in orchestrating actin cytoskeleton, leading to EMT and cancer invasion. However, the underlying mechanisms for ROCKs activation are not fully understood. Here, we identified FOXM1D, a novel isoform of Forkhead box M1 (FOXM1) that has a pivotal role in ROCKs activation by directly interacting with coiled-coil region of ROCK2. FOXM1D overexpression significantly polymerizes actin assembly and impairs E-cadherin expression, resulting in EMT and metastasis in xenograft mouse model and knockdown of FOXM1D has the opposite effect. Moreover, a high FOXM1D level correlates closely with clinical CRC metastasis. FOXM1D-induced ROCKs activation could be abrogated by the ROCKs inhibitors Y-27632 and fasudil. These observations indicate that the FOXM1D-ROCK2 interaction is crucial for Rho/ROCKs signaling and provide novel insight into actin cytoskeleton regulation and therapeutic potential for CRC metastasis.

Abstract
OBJECTIVE The present study has been planned to explore the relationship between P13K/AKT signal pathway-mediated matrix metalloproteinase-9 (MMP-9) gene and lung cancer. PATIENTS AND METHODS The adjacent lesion tissues were removed from 68 cases of patients with lung cancer admitted to our hospital from February 2013 to February 2015. They were selected as observation group, and the pulmonary adjacent normal section specimens from 18 cases were taken as control group. The differences in expression quantities of P13K, AKT and MMP-9 genes in adjacent lesion tissues and adjacent normal tissues were detected by fluorescence quantitative PCR technology, enzyme-linked immunosorbent assay (ELISA), Western-blotting technology and immunohistochemical technique and SP staining technology. RESULTS The mRNA expression quantities of P13K, AKT and MMP-9 genes in adjacent lesion tissues increased significantly in comparison to adjacent normal tissues, and the differences were statistically significant (p<0.05). The results of Spearman correlation detection showed that the expression quantity of MMP-9 in adjacent lesion tissues had a significantly positive correlation with that of P13K and AKT (r=0.232, p<0.05). CONCLUSIONS MMP-9 gene could promote the generation of lung cancer through P13K/AKT signal pathway, which provides certain theoretical and experimental basis for subsequent diagnosis and treatment of lung cancer.

Abstract
The commonly used Bacillus Calmette-Guérin (BCG) vaccine only induces moderate T cell responses and is less effective in protecting against pulmonary tuberculosis (TB) in adults and ageing populations. Thus, developing new TB vaccine candidates is an important strategy against the spread of Mycobacterium tuberculosis. Here, we demonstrated that immunization with heat-shock protein gp96 as an adjuvant led to a significantly increased CD4(+) and CD8(+) T cell response to a BCG vaccine. Secretion of the Th1-type cytokines was increased by splenocytes from gp96-immunized mice. In addition, adding gp96 as an adjuvant effectively improved the protection against intravenous challenge with Mycobacterium bovis BCG in mice. Our study reveals the novel property of gp96 in boosting the vaccine-specific T cell response and its potential use as an adjuvant for BCG vaccines against mycobacterial infection.
