Abstract
OBJECTIVE To assess the efficacy of metformin in megestrol acetate (MA)-based fertility-sparing treatment for patients with atypical endometrial hyperplasia (AEH) and endometrioid endometrial cancer (EEC). DESIGN A randomised, single-centre, open-label, controlled trial conducted between October 2013 and December 2017. SETTING Shanghai OBGYN Hospital of Fudan University, China. POPULATION A total of 150 patients (18-45 years old) with primary AEH or well-differentiated EEC were randomised into an MA group (n = 74) and an MA plus metformin group (n = 76). METHODS Patients with AEH or EEC were firstly stratified, then randomised to receive MA (160 mg orally, daily) or MA (160 mg orally, daily) plus metformin (500 mg orally, three times a day). MAIN OUTCOMES AND MEASURES The primary efficacy parameter was the cumulate complete response (CR) rate within 16 weeks of treatment (16w-CR rate); the secondary efficacy parameters were 30w-CR rate and adverse events. RESULTS The 16w-CR rate was higher in the metformin plus MA group than in the MA-only group (34.3 versus 20.7%, odds ratio [OR] 2.0, 95% confidence interval [CI] 0.89-4.51, P = 0.09) but the difference was more significant in 102 AEH patients (39.6 versus 20.4%, OR 2.56, 95% CI 1.06-6.21, P = 0.04). This effect of metformin was also significant in non-obese (51.4 versus 24.3%, OR 3.28, 95% CI 1.22-8.84, P = 0.02) and insulin-sensitive (54.8 versus 28.6%, OR 3.04, 95% CI 1.03-8.97, P = 0.04) subgroups of AEH women. No significant result was found in secondary endpoints. CONCLUSION As a fertility-sparing treatment, metformin plus MA was associated with a higher early CR rate compared with MA alone in AEH patients. TWEETABLE ABSTRACT For AEH patients, metformin plus MA might be a better fertility-sparing treatment to achieve a higher early CR rate compared with MA alone.

Abstract
Immunocastration (vaccination against Gonadotropin-releasing hormone (GnRH)) has been regarded as a friendly substitution to physical castration in animals. To date, a few studies have reported the use of Improvac for immunocastration in boar and one study in broiler chickens; however, there is an apparent dearth of scientific evidence regarding the application of Improvac for immunocastration in birds. In the present study, we evaluated the effects of Improvac-based immunocastration on testosterone levels and spermatogenesis in broiler chickens and the effects of Improvac on the expression of genes related to testosterone biosynthesis and metabolism as well as spermatogenesis. The birds were randomly divided into 4 groups (n = 30 each): Control group (non-immunized), Early group (immunized with Improvac at week 3), Late group (immunized with Improvac at week 6), and Early + Late group (immunized with Improvac at weeks 3 and 6). Immunization with Improvac significantly improved the average daily gain compared to the Control group. Of note, following Improvac vaccination, the reproductive efficiency was significantly decreased in male broiler chickens. Furthermore, parameters such as the serum testosterone concentration, spermatogenesis, and the expression levels of genes related to testosterone metabolism (Cyp17A1, Cyp19, HSD3B1, and HSD17B3) and spermatogenesis (Cyclin A1 and Cyclin A2) were significantly reduced in the immunized groups compared to the Control group. Taken together, these findings reveal that immunization against GnRH can be achieved, at least partially, in male broiler chickens. The results of our study also support the hypothesis of using Improvac as an alternative solution to caponization, with considerably improved animal welfare.

Abstract
PURPOSE Epithelial to mesenchymal transition (EMT) plays an important role in acquired resistance to gefitinib in lung cancer. This study aimed to explore the underlying mechanism of gefitinib-induced EMT in lung adenocarcinoma cells harboring EGFR mutation. METHODS CXC chemokine receptor 4 (CXCR4) expression was determined through qRT-PCR, Western blot and flow cytometry assays in lung cancer cell line (PC9) bearing mutated EGFR. Functional role of CXCR4 was inhibited applying siRNAs as well as the specific antagonist AMD3100. The expression of EMT markers was determined, and the migration of PC9 cells was measured with transwell assay. RESULTS We found that gefitinib promoted the migratory capacity of PC9 cells in vitro, which correlated with EMT occurrence through upregulation of CXCR4. Blocking CXCR4 significantly suppressed gefitinib-induced enhancement of migration and EMT. Moreover, we determined that the upregulation of CXCR4 by gefitinib was dependent on TGF-β1/Smad2 signaling activity. CONCLUSIONS Our study suggested a potential mechanism by which gefitinib induced EMT in cells harboring EGFR mutation through a pathway involving TGF-β1 and CXCR4. Thus, the combination of CXCR4 antagonist and TGFβR inhibitors might provide an alternative strategy to overcome progression of lung cancer after gefitinib treatment.

Abstract
This study sought to investigate Chinese farmers' attitude towards animal welfare by using the Theory of Planned Behaviour (TPB). According to the TPB, an individual's intention to behave in a certain way is determined by his/her attitude towards the behaviour (specific attitude —
importance — and general attitudes), the perceived behavioural control (easiness), and the supposed opinion of the people who are important to him/her (subjective norms). A total of 253 questionnaires are used, which included the three main animal productions in chena (swine, poultry
and cattle). Chinese farmers have perceived the improvement of animal welfare as two abstracts: general attitudes (reward-seeking, and empathic farmer); and four specific categories of actions (favourable environment, animal health, humane treatment of animals and farmers' well-being). Our
analysis revealted that general and specific attitudes were the strongest predictors of farmers' intentions to improve animal welfare in the questionnaire study. In fact, Chinese farmers considered it fairly important to improve the animal welfare meaures considered in the survey. In contrast,
the same animal welfare measures were considered difficult to improve by the farmers as indicated by the lack of association between the easiness of improving animal welfare and the intentions. In addition, veterinarians, agricultural advisers, and scientific experts were considered to be
relatively influential subjective norms as regards the activities of the farmers. This is the first study to provide an insight into the underlying meanings and values of Chinese farmers views on improvements to animal welfare.

Abstract
OBJECTIVE MicroRNAs (miRNAs/miRs) are small noncoding RNAs that primarily function in RNA silencing and gene regulation at the posttranscriptional level in animals, plants and certain viruses. They have been reported to play a vital role in development and progression of diseases such as cancer. The present study was undertaken to establish a correlation between a specific miRNA in this cluster, termed miR92a, and its association with nonsmall cell lung cancer (NSCLC). MATERIALS AND METHODS Total RNA was isolated from the plasma using an RNeasy mini kit and cDNA was synthesized by TaqMan MicroRNA Reverse Transcription kit. The expression of miR-92a was quantified by quantitative Real-time PCR (RT-PCR). All transfections were performed using Lipofectamine 2000. Digoxigenin (DIG)labeled locked nucleic acid (LNA)modified probes for miR92a and negative control oligonucleotides were used for in vitro hybridization following manufacturers protocol. Digoxigenin (DIG)labeled locked nucleic acid (LNA)modified probes for miR92a and negative control oligonucleotides (miRCURY LNA MicroRNA Detection Probes; Exiqon, Vedbaek, Denmark) were used. Cell proliferation was examined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) MTT assay. RESULTS It was observed that miR92a is highly expressed in NSCLC compared with adjacent tissue samples and plasma from healthy donors. Additionally, the proliferation of three NSCLCderived cell lines, SPCA1, A549 and H2170, was enhanced by miR92a and inhibited by a complementary antimiR92a oligonucleotide sequence. Although the underlying mechanisms of reduced cellular proliferation in the presence of miR92a antagomirs cannot be explained from the current results. CONCLUSIONS The upregulation of miR92a expression, in cells and plasma, is manifested during the development of NSCLC.

Abstract
OBJECTIVE Drug-induced liver injury has become a serious public health problem that cannot be ignored. Although the mechanism of acetaminophen (APAP)-induced liver injury has been investigated for several decades, there are still many deficiencies. However, only a deeper study of its mechanism can provide more effective measures of prevention and treatment for APAP-induced liver injury. The aim of this study was to investigate whether toll-like receptor 4 (TLR4) participates in and regulates APAP-induced liver injury, which may provide a new direction for the prevention and treatment of clinical drug-induced hepatitis. MATERIALS AND METHODS WT mice were treated with APAP (300 mg/kg) or equivalent PBS. The livers of mice were taken at 1 h, 3 h, 6 h and 12 h after treatment. Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) was used to detect TLR4 mRNA expression level in the liver. After TLR4 involving in APAP-induced liver injury was confirmed, we investigated the relationship between TLR4 expression and hepatic inflammation. WT and TLR4-/- mice received APAP (3000 mg/kg) intraperitoneal injection after 16 h of fasting; serum was collected after 8 h and 24 h, and serum alanine aminotransferase (ALT) and reduced glutathione (GSH) activity were measured. Rat liver tissue was observed for histological changes by hematoxylin and eosin (H&E) staining. RT-qPCR and enzyme-linked immunosorbent assay (ELISA) assay were performed to analyze proinflammatory cytokines expression (such as TNF-α, IL-1β, MCP-1, IL-6). After isolating mononuclear cells (MNCs) in the liver of mice, flow cytometry was used to detect cell activation level and infiltration of macrophages and neutrophils. Western blotting was used to analyze the activation of phosphorylated JNK and p38 signaling pathways in livers of WT and TLR4-/- mice. In addition, after stimulated with APAP, the silence of TLR4 in RAW264.7 cells could activate phosphorylated JNK and p38 signaling pathways. RESULTS After APAP stimulation, WT mice exhibited more severe liver injury than TLR4-/- mice, with higher ALT levels, lower GSH levels, and more necrotic or apoptotic cells. TLR4-/- mice have lower levels of inflammatory cytokines including MCP-1 and IL-6; at the same time, the number of infiltrating macrophages and neutrophils in liver tissue of TLR4-/- mice was significantly lower than that of WT mice. The activation of JNK signaling pathway was strikingly enhanced in WT mice treated with APAP, but no significant difference was observed in the activation of JNK phosphorylation in TLR4-/- mice after the same dose of APAP stimulation. Similarly, in RAW264.7 cells, the activation of phosphorylated JNK and p38 was remarkably inhibited by TLR4-siRNA, but was activated in the control group, which was consistent in vivo. CONCLUSIONS APAP-treated TLR4-/- mice showed milder liver injury compared to WT mice. It was confirmed that TLR4 could activate the JNK signaling pathway to induce the secretion of inflammatory factors and the infiltration of macrophages to promote APAP-induced liver injury. This finding might provide a new prevention and treatment idea for clinical drug-induced hepatitis.

Abstract
BACKGROUND AND PURPOSE Zero TE-MRA is less sensitive to field heterogeneity, complex flow, and acquisition noise. This study aimed to prospectively validate the feasibility of zero TE-MRA for cerebrovascular diseases assessment, compared with TOF-MRA. MATERIALS AND METHODS Seventy patients suspected of having cerebrovascular disorders were recruited. Sound levels were estimated for each MRA subjectively and objectively in different modes. MRA image quality was estimated by 2 neuroradiologists. The degree of stenosis (grades 0-4) and the z-diameter of aneurysms (tiny group ≤3 mm and large group >3 mm) were measured for further quantitative analysis. CTA was used as the criterion standard. RESULTS Zero TE-MRA achieved significantly lower subjective perception and objective noise reduction (37.53%). Zero TE-MRA images showed higher signal homogeneity (3.29 ± 0.59 versus 3.04 ± 0.43) and quality of venous signal suppression (3.67 ± 0.47 versus 2.75 ± 0.46). The intermodality agreement was higher for zero TE-MRA than for TOF-MRA (zero TE, 0.90; TOF, 0.81) in the grading of stenosis. Zero TE-MRA had a higher correlation than TOF-MRA (zero TE, 0.84; TOF, 0.74) in the tiny group and a higher consistency with CTA (intraclass correlation coefficient, 0.83; intercept, -0.5084-1.1794; slope -0.4952 to -0.2093) than TOF-MRA (intraclass correlation coefficient, 0.64; intercept, 0.7000-2.6133; slope -1.0344 to -0.1923). Zero TE-MRA and TOF-MRA were comparable in the large group. Zero TE-MRA had more accurate details than TOF-MRA of AVM and Moyamoya lesions. CONCLUSIONS Compared with TOF-MRA, zero TE-MRA achieved more robust performance in depicting cerebrovascular diseases. Therefore, zero TE-MRA was shown to be a promising MRA technique for further routine application in the clinic in patients with cerebrovascular diseases.

Methods: According to the inclusion and exclusion criteria, we selected 319 puerperae and their infants in maternal hospitals of Songjiang district November 2016 to February 2017, venous blood were collected and serum measles and rubella IgG antibodies were measured using ELISA. To study the correlation between the level of measles and rubella antibodies in infants and mothers' by using the Spearman's correlation analysis. Results: The age at delivery was (29.71±4.25) years old; and the gestational age at delivery was (39.06±1.30) weeks. The positive rate and protection rate of measles antibody in puerperae were 82.5% (243/319) and 43.3% (135/319), the GMC [M (QR)] was 655.74 (251.21-1 299.02) mIU/ml. The positive rate of rubella antibody in puerperae was 61.1% (195/319), the GMC [M (QR)] was 31.34 (11.65-73.61) IU/ml. The positive rate and protection rate of measles antibody in infants were 84.1% (270/321) and 46.1% (148/321), the GMC [M (QR)] was 665.07 (279.63-1 544.07) mIU/ml. The positive rate of rubella antibody in infants was 69.5% (223/321), the GMC [M (QR)] was 40.30 (16.12-98.48) IU/ml. There was statistical difference in measles (Z=-14.64, P<0.001) and rubella (Z=-8.66, P<0.001) antibody levels between mothers and infants. There was positive correlation in measles (r=0.76, P<0.001) and rubella (r=0.86, P<0.001) antibody level between mothers and infants. Conclusion: The maternal antibody of measles and rubella had a concentration effect. The level of measles and rubella antibodies in the infants was higher than that in the mothers' and increased with the increase of the level of measles and rubella antibodies in the mothers.

Abstract
Aim: To compare the pharmacokinetic profiles of tilmicosin, administered orally at a single dose of 20 mg/kg bodyweight, in healthy pigs and in pigs experimentally infected with Actinobacillus pleuropneumoniae. Methods: Twelve healthy crossbred pigs, aged approximately 8 weeks, were randomly assigned to uninfected and infected groups, with six pigs per group. Pigs in the infected group were inoculated intranasally with a bacterial suspension of A. pleuropneumoniae containing approximately 108 cfu. Each pig received a single oral dose of 20 mg/kg bodyweight of tilmicosin, given 3-4 hours after inoculation in infected pigs. Blood samples were collected before drug administration and up to 48 hours after tilmicosin administration. Concentrations of tilmicosin in plasma samples were determined by HPLC. Throughout the experimental period pigs were observed for signs of inappetence and clinical abnormalities. After sampling was complete pigs were subject to euthanasia and samples collected for gross and histopathology as well as microbiology. Results: Infected pigs showed signs of bradykinesia, nasal discharge dyspnoea, and coughing 1 hours after inoculation and A. pleuropneumoniae was cultured from the lungs of all infected pigs postmortem. Comparing pharmacokinetic parameters in uninfected and infected pigs, the maximum plasma concentration of tilmicosin was higher in uninfected pigs (1.17 (SD 0.17) vs. 0.96 (SD 0.17) µg/mL), the time to reach maximum concentration was shorter (1.53 (SD 0.23) vs. 2.40 (SD 0.37) hours), and the half-life of the absorption phase and half-life of the elimination phase were both shorter (0.66 (SD 0.08) vs. 1.00 (SD 0.27) hours) and (12.93 (SD 0.96) vs. 16.53 (SD 0.55) hours), respectively. The apparent volume of distribution was smaller in uninfected than infected pigs (1.91 (SD 0.22) vs. 2.16 (SD 0.21) L/kg). The relative bioavailability of tilmicosin in infected relative to uninfected pigs was 108.6 (SD 9.71)%. Conclusions and clinical relevance: The results of this study indicate that A. pleuropneumoniae infection significantly changed certain pharmacokinetic parameters of tilmicosin in pigs. In infected pigs tilmicosin exhibited a longer drug persistence and a better extent of absorption. These results indicate that it is necessary to monitor and adjust the dose of tilmicosin administration during the presence of pleuropneumonia. It is expected that this can optimise clinical efficacy and help avoid the development of resistance.

Abstract
Aim Intrauterine growth retardation (IUGR) is a prevalent problem in mammals. The present study was conducted to unveil the alterations in intestinal microbiota in IUGR piglets. Methods and Results We identified the alterations of small intestinal microbiota in IUGR piglets on 7, 21 and 28 days of age using 16S rRNA sequencing. The results showed that IUGR piglets had a decreased alpha diversity of jejunum microbiota at 7 and 21 days of age; had lower abundances of Bacteroidetes and Bacteroides in the jejunum at 7, 21 and 28 days of age, Oscillibacter in the jejunum at 21 days of age, and Firmicutes in the ileum at 21 days of age; whereas they had higher abundances of Proteobacteria and Pasteurella in the ileum at 21 days of age and Escherichia–Shigella in the jejunum at 28 days of age. Correlation analysis showed that Bacteroides, Oscillibacter and Ruminococcaceae_UCG‐002 compositions were positively associated with the body weight (BW) of IUGR piglets, nevertheless Proteobacteria and Escherichia–Shigella relative abundances were negatively correlated with the BW of IUGR piglets. Gene function prediction analysis indicated that microbiota‐associated carbohydrate metabolism, lipid metabolism, glycan biosynthesis and metabolism, amino acid metabolism, and xenobiotics biodegradation and metabolism were downregulated in the IUGR piglets compared to control piglets. Conclusions The present study profiled the intestinal microbiota of newborn piglets with IUGR and the newborn IUGR piglets have lower diversity and different taxonomic abundances. Alterations in the abundances of Bacteroidetes, Bacteroides, Proteobacteria Escherichia–Shigella and Pasteurella may be involved in nutrient digestion and absorption, as well as the potential mechanisms connecting to the growth and development of IUGR in mammals. Significance and Impact of the Study The small intestinal microbiota were highly shaped in the IUGR piglets, which might further mediate the growth and development of IUGR piglets; and the gut microbiota could serve as a potential target for IUGR treatment.

Abstract
Objective: To investigate the health status, functional ability, mental psychology, health care and other longevity-related characteristics of individuals aged ≥100 years as well as risk factors in Hainan province, China. Methods: China Hainan Centenarian Cohort Study (CHCCS) is a community-based, prospective cohort study to establish multi-dimensional database consisting of questionnaire findings, anthropometric parameters and biological specimens as well as imaging features. With the household registration information provided by the Department of Civil Affairs of Hainan province, a baseline survey was conducted in centenarians in 18 counties in Hainan with the oldest old in 5 counties as controls between 2014 and 2017. The survey included face to face interview, physical examination and biological specimen collection. After the baseline survey, the participants of CHCCS were followed up at an interval of 2 years to collect the information about their living status, disease status or major death causes. Results: According to the information provided by the Department of Civil Affairs of Hainan province in 2014, the survey found that 1 473 centenarians were still living. By December 2016, 1 002 of them had agreed to be surveyed. The average age of 722 centenarians with complete information in the baseline survey was (102.7±2.7) years, the majority of them were females (83.0%), widows (88.8%), in Han ethnic group (84.5%), lived with family members (87.8%), illiterates (89.7%) and farmers (81.0%). Conclusion: CHCCS has provided longevity-related information of the large longevity population and collected the valuable and rare biological specimens with great urgency to establish an interdisciplinary platform and base for longevity, senility and healthy aging research.

Abstract
Objective: To understand the major high risk behaviors and related factors among reported HIV/AIDS cases aged ≥60 years in some areas of Henan province. Methods: In Dengzhou, Xunxian county of Hebi and Xiangcheng county of Xuchang, where the reported number and proportion of HIV/AIDS cases aged ≥60 years were high, a face to face interview was conducted among the cases aged ≥60 years during July-August in 2016. The information about the high risk behaviors before HIV infection confirmation were collected by using a semi-structured questionnaire. Results: A total of 33 HIV/AIDS cases aged ≥60 years were interviewed, including 28 males and 5 females. Their average age was 67.4 years. The infection route was sexual contact. The main findings revealed that the main factor for HIV infection in elder males was commercial heterosexual behavior with local female sex workers. The condom use rate was low. The poor awareness of the knowledge about AIDS prevention could explain why the elderly could not recognize the risk of HIV infection. There were also homosexual and bisexual behaviors in elder male HIV/AIDS patients. Late detection of HIV transmission among couples was the main cause of HIV infection in elder women. Conclusions: The major epidemiological related factors for HIV infection in the elderly in some areas of Henan were unsafe sex behavior and the poor awareness of knowledge about AIDS prevention. A targeted strategy should be taken to control the spread of HIV in the elderly.

Abstract
Background Abhydrolase domain containing 5 (ABHD5) functions as a tumor suppressor in colorectal and prostate cancers. The aim of this study was to investigate the roles of ABHD5 in endometrial cancer. Materials and methods ABHD5 expression was detected in clinical samples by immunohistochemical staining. Cell proliferation and invasion were evaluated with the Cell Counting Kit-8 and Transwell assay, respectively. Western blotting was performed to analyze protein expression. Glucose uptake was assessed by 2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino]-2-deoxyglucose. Lactate production was detected by a lactate assay kit. Results In the present study, ABHD5 was overexpressed in endometrial cancer tissues, and its expression was closely correlated with the International Federation of Gynecology and Obstetrics (FIGO) stage and lymph node metastasis. In addition, we observed that the knockdown of ABHD5 inhibited cell proliferation, invasion, glucose uptake and lactate production in HEC-1A cells, which expressed high levels of ABHD5. Conversely, the opposite effects were observed when ABHD5 was ectopically expressed in Ishikawa cells, which had low levels of ABHD5. Furthermore, the changes in glycolysis regulators (enolase 1 [ENO1], glucose transporter 1 [GLUT1] and lactate dehydrogenase A [LDHA]) and epithelial-to-mesenchymal transition-related proteins (E-cadherin and Snail) in HEC-1A cells with ABHD5 knockdown were consistent with the effects of ABHD5 on glycolysis and cell invasion. Phosphatase and tensin homolog deleted on chromosome 10 (PTEN) was increased, while the phosphorylated AKT (p-AKT) was decreased when ABHD5 was downregulated. Notably, treatment with the allosteric AKT inhibitor MK-2206 completely abolished the effects caused by ABHD5 overexpression in Ishikawa cells. Finally, ABHD5 knockdown potently suppressed tumor growth in vivo. Conclusion Overall, these results suggest that ABHD5 may play an oncogenic role in endometrial cancer via the AKT pathway.
