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
Abstract
Background: Some population-base studies have reported similar or improved survival for breast-conserving surgery (BCS) plus radiotherapy compared with mastectomy (Mx) in early breast cancer [PMID: 22373563, 27344114]. Among the screening detected early breast cancer, ultrasound (US) could detect more invasive non-palpable breast cancer (NPBC) with positive lymph nodes in hospital-based asymptomatic Chinese women, who could achieve comparable 10-year DFS and OS as mammography (MG)-detected NPBC [2016 SABCS P5-02-05, PMID: 27689334]. However, there is little data about the surgical outcomes of BCS verse Mx in the low-risk screening detected NPBC with US as the initial imaging test.
Methods: From 2001 to 2017, 6,423 consecutive asymptomatic women underwent mammography or ultrasound guided biopsy in Peking Union Medical College Hospital. Among them, 1130 NPBC including 914 US-detected and 216 MG-detected NPBC were diagnosed and treated. There were 349 (30.9%) patients underwent BCS including 286 (25.3%) patients received radiation therapy and 63 (5.6%) elderly patients (>70 years) who did not. The clinicopathological features, treatment choice, 10-year disease-free survival (DFS) and overall survival (OS) were compared between breast conservingsurgery (BCS) versus mastectomy(Mx) in all NPBC and between the US-detected and MG-detected NPBC.
Result: Compared to those who received BCS, the 781 (69.1%) patients who underwent Mx had more cancers with relatively higher histologic grade (p=0.003), positive lymph node (18.8% vs 12.0%, p=0.005), ER-negative (22.5% vs 11.5%, p<0.001), PR-negative (29.6% vs 16.3, p<0.001), Her2-positive (16.3% vs 8.9%, p=0.001), and received chemotherapy (37.6% vs 28.7%, p=0.003). The breast conserving rates of US-NPBCwere higher than that of MG-NPBC (32.6% vs 23.6%, p=0.010), but the breast conserving rates were similar between ductal carcinoma in situ (DCIS) and invasive cancers. The 10-year DFS and OS were similar among BCS with radiation therapy, BCS without radiation therapy and Mx as well as among US-NPBC with BCS, US-NPBC with Mx, MG-NPBC with BCS and MG-NPBC with Mx. However, MG-NPBC with Mx had favorable 10-year DFS than that of MG-NPBC with BCS (p=0.041).

Conclusion: The 10-year DFS and OS of breast conserving surgery versus mastectomy were similar among all NPBC patients. As the current initial imaging test, US-detected NPBC patients would receive significantly more BCS compared to MG. There was no significant difference in surgical outcomes among BCS and Mx in US-detected NPBC. However, among MG-detected NPBC, patients with Mx reached a better DFS but a similar OS than those with BCS. The radiation therapy could be safely omitted in the elderly patients (>70 years) with NPBC.

Abstract
Abstract
Background: Ultrasound (US) is an effective initial screening test for breast cancer both in Caucasian and Chinese women [PMID: 26712110, 26715161, and 25668012]. The real-world modality of breast cancer screening in the China is hospital-based screening among asymptomatic self-referred women. In our previous study, we showed that US and mammography (MG) detected non-palpable breast cancer (NPBC) had similar long-term survival and that US detected more invasive NPBC with positive lymph node [2016 SABCS P5-02-05, PMID: 27689334]. This study was to investigate whether these findings would be still true with more NPBC cases included and longer follow-up in the consecutive hospital cohort.
Methods: From 2001 to 2017, 5,264 asymptomatic women with positive (BI-RADS 4 and 5) initial screening US underwent biopsies in PUMC Hospital, and 914 US-NPBC in 883 women were diagnosed. Meanwhile, women without dense breasts (defined as BI-RADS category C and D) also received screening MG after physical examination and US. There were 1,159 patients with positive (BI-RADS 4 and 5) MG and normal US (BI-RADS 1, 2 and 3) underwent MG-guided biopsies and 216 MG-NPBC were diagnosed in 214 women. The clinicopathological characteristics and 10-year disease-free survival (DFS) and overall survival (OS) were reviewed and compared between the US-NPBC and MG-NPBC. Prognostic factors of NPBC were identified by univariate and multivariate Cox analysis.
Result: Compared to MG, US could detect more invasive (81.2% vs 48.6%, p<0.001), lymph node positive (18.3% vs 10.2%, p<0.001), stage II+III (21.7% vs 12.5%, p<0.001) and low grade cancer (p=0.001).Between invasive US-NPBC and MG-NPBC, no significant difference was identified for lymph node status, TNM stage or subtype.US-NPBC received more breast conserving surgery (32.6% vs 24.1%, p<0.001) and chemotherapy (37.5% vs 23.6%, p<0.001). There was no significant difference in DFS or OS between US- vs MG-NPBC among ductal carcinoma in situ (DCIS), invasive and all NPBC. For the US-NPBC, the DFS factors included TNM stage and Hormone receptor status whereas OS-predictors were pN and subtype.

Conclusion: Overall, US could detect more invasive NPBC patients with positive lymph node and advanced stage compared to MG, and screen invasive NPBC at similar TNM stage and subtype distribution as MG. US-NPBC patients received more breast conserving surgery and chemotherapy, and could achieve comparable 10-year DFS and OS as MG-detected NPBC. Hence US is justified in the real-world as the initial imaging modality in hospital-based screening Chinese women.

Abstract
BACKGROUND In the West, the safety and efficacy of the Lotus valve have been demonstrated; however, data in the Chinese population are still lacking. Few studies have compared the clinical outcomes of transcatheter aortic valve replacement (TAVR) with the Lotus valve in patients with bicuspid or tricuspid aortic valve stenosis. Our aim was to assess TAVR outcomes with the Lotus aortic valve in a Chinese patient cohort. METHODS In total, 23 symptomatic, high-surgical risk patients with severe aortic valve stenosis were enrolled. Among them, nine patients (39%) had bicuspid aortic valves, and three patients had a large annulus dimension. The Lotus valve was successfully implanted in all patients. To facilitate accurate positioning, partial re-sheathing was attempted in ten patients (43.5%), while one patient had a full retrieval. One-year clinical follow-up was completed in all patients. RESULTS There were no deaths, strokes, or major adverse cardiac and cerebrovascular events in 22 of the 23 patients at 30 days; the all-cause mortality rate at 1 year was 4.4% (1 of 23 patients). The mean aortic valve gradient decreased from 51.5 ± 8.8 mm Hg at baseline to 13.4 ± 4.9 mm Hg (p < 0.001) and the valve area increased from 0.6 ± 0.2 cm2 to 1.5 ± 0.4 cm2 (p < 0.001) at 30 days. Paravalvular leakage was absent or mild (22%), and no patient had severe paravalvular leakage. Six patients (26.1%) required a postprocedural pacemaker. There was no difference regarding the procedural and the 1‑year outcomes between patients with bicuspid and tricuspid aortic valve stenosis. CONCLUSION Our single-center experience demonstrated that the Lotus valve is feasible and effective for Chinese patients with aortic valve stenosis, including atypical cases with bicuspid aortic valves or large aortic annulus size.

Abstract
Trace elements are key regulators of metabolism and physiological pathways, and their levels change during aging. Hair, as a biological sample, has attracted much attention due to its ease of collection and slow substance metabolism. Also, trace elements in hair can reveal the distribution of essential nutrients and toxic elements in the body pools. Therefore, we investigated the lifestyle and dietary status by questionnaire and measured 8 trace elements in hair and 6 elements in blood of a sample of elders over 80 residing in Hainan province of China. Our data showed that the concentration of Se, Fe and Pb dropped as people grow older, but Mn rose. Changes in trace elements may affect enzyme activity and biological pathways, and are associated with many diseases, including cancer and chronic diseases. In addition, association between age-related diseases and trace elements are increasingly being reported, suggesting that approaches of combining nutrition with longevity studies in the further study will help us to identify the mechanisms whereby trace elements affect the aging process.

Abstract
OBJECTIVES This study aims to investigate the prevalence of vitamin D deficiency in Chinese centenarians and to identify the factors associated with vitamin D deficiency. DESIGN Cross-sectional population-based study. SETTING Hainan province in the south of China. PARTICIPANTS 943 subjects aged 100 years old and older. METHODS Details on sociodemographics and lifestyle characteristics were collected using a structured questionnaire. Anthropometrics and blood samples were obtained. Vitamin D deficiency was defined as serum 25-hydroxyvitamin D concentration < 20ng/mL (50nmol/L). RESULTS The overall prevalence of vitamin D deficiency among these 943 centenarians was 39.9% (376 subjects) and the mean serum vitamin D concentrations were 22.7±9.5 (ng/mL). Female centenarians had higher prevalence of vitamin D deficiency than male (44.0% vs. 21.7%, P <0.001). Multivariate logistic regression analyses showed that being female, urban residency, lower body mass index, higher serum parathyroid hormone levels, no fish consumption, and less sun exposure time were all significant and independent determinants of vitamin D deficiency. No significant associations of vitamin D deficiency with ethnic, education, geographic location, tea drinking, alcohol use, or smoking were found in this study. CONCLUSION Vitamin D deficiency was common in Chinese centenarians, especially in women. Given that vitamin D deficiency is linked to numerous adverse health outcomes, dietary, outdoor activities and other intervention measures are needed to correct vitamin D deficiency in this population.

Abstract
BACKGROUND Obesity puts a great health burden in the world. Previous studies suggest that caesarean section (CS) may increase the risk of obesity in children, but it is still uncertain whether this association is causal or due to residual confounding by medical indication. AIM To assess the association between CS, CS without medical indications in particular and the risk of overweight and obesity in school-aged children. DESIGN Cross-sectional survey. METHODS The 2014 Shanghai Child Health, Education and Lifestyle Evaluation was a large population-based survey with cluster random probability sampling in 26 primary schools in Shanghai, China, in 2014. The mode of delivery was reported by parents. The height, weight and waist circumference of the children were measured. Logistic regression models with SURVEYLOGISTIC procedure were used to estimate the risk of childhood obesity. Pupils delivered vaginally were served as the reference group. RESULTS A total of 17 571 pupils completed this survey, and 13 724 of them who were singleton, born term and between 5 and 13 years old were included in our analysis. CS was associated with increased risks of overweight and obesity (BMI: adjusted OR = 1.28 [95%CI 1.13-1.45] and 1.44 [1.26-1.66], respectively; weight for height ratio [WHtR] >0.46: 1.33 [1.20-1.48]). Similar results were found in CS without medical indication (BMI: overweight = 1.24 [1.05-1.47], obesity = 1.43 [1.19-1.72]; WHtR > 0.46: 1.30 [1.13-1.50]). CONCLUSIONS CS overall and CS without medical indications were associated with increased risks of overweight and obesity in primary school children.

Abstract
Objectives The aim of this study is to investigate the sex-specific aortic root anatomy in patients with bicuspid aortic valve (BAV). Patients and methods This retrospective study includes 73 consecutive patients with BAV who underwent CT evaluation before transcatheter aortic valve replacement (TAVR) between July 2013 and April 2017 in the Second Affiliated Hospital of Zhejiang University. Result The size of the annulus, diameter and height of the sinotubular junction (STJ), height of the coronary artery ostia, and dimension of the aorta were measured. Women had significantly smaller annulus parameters (mean diameter: 23.4 ± 1.8 vs. 26.1 ± 2.1 mm; area: 425.3 ± 59.4 vs. 527.4 ± 84.6 mm2; perimeter: 74.3 ± 5.2 vs. 83.2 ± 6.4 mm), and STJ diameter (29.7 ± 3.1 vs. 32.6 ± 4.5 mm) than men (p < 0.01 for all), even after adjustment for their smaller body surface area (BSA). Dimension of aorta and height of right coronary artery were also significantly smaller in women, although not when indexing for the BSA. The left ventricular ejection fraction of women is significantly higher than that of men before discharge (60.2 ± 9.7% vs. 53.7 ± 13.6%, p = 0.01). There were no differences between women and men in the all-cause 30-day and 1‑year mortality. Conclusion Women with BAV had smaller annulus and STJ diameter after indexing for BSA, reflecting a sex-specific difference. There were no differences in 30-day and 1‑year mortality between the two groups.

Abstract
Background Fibroblast growth factor 13 (FGF13) is one of the most highly expressed FGF family members in adult mouse ovary. However, its precise roles in ovarian function remain largely unknown. We sought to evaluate the associations between FGF13 in follicular fluid and oocyte developmental competence in patients with polycystic ovary syndrome (PCOS). Methods A cross-sectional study was conducted on 43 patients with PCOS and 32 non-PCOS patients who underwent in vitro fertilization/intracytoplasmic sperm injection treatments. The highest quartiles of follicular fluid (FF)-FGF13 (≥117.51 pg/mL) and FF-total testosterone (FF-TT) (≥51.90 nmol/L) were defined as “elevated” FF-FGF13 levels and “elevated” FF-TT levels, respectively. Results The levels of FF-FGF13 were skewed, with a median of 82.97 pg/mL (59.79–117.51 pg/mL) in 75 patients. The prevalence of elevated FF-TT levels was significantly higher in the PCOS patients with elevated FF-FGF13 levels than in those without (64.3% vs. 35.7%, adjusted P = 0.0096). FF-TT and increased ovarian volume (> 10 mL for one or both ovaries) were positively correlated with FF-FGF13 in PCOS patients (r = 0.37, P = 0.013; r = 0.33, P = 0.032). A negative association was evident between FF-FGF13 and the MII oocyte rate in the multiple linear regression analysis (β = − 0.10, SE = 0.045, adjusted P = 0.027). However, the associations were not evident in the non-PCOS patients. Conclusions Our study suggests the presence of intrafollicular FGF13 in PCOS patients and implies that FGF13 might be involved in the pathophysiological process of PCOS.

Abstract
OBJECTIVE To investigate cross-sectional associations between serum level of Matrix metalloproteinase (MMP)13 and knee structural measures and circulating inflammatory factors in patients with symptomatic knee osteoarthritis (OA). DESIGN A total of 149 subjects with symptomatic knee OA were included. Magnetic resonance imaging was used to measure infrapatellar fat pad (IPFP) volume, IPFP signal intensity alternation, cartilage volume and cartilage defects. Knee radiography was used to assess radiographic OA using the Kellgren-Lawrence (K-L) grading system. Enzyme-linked immunosorbent assay was used to measure the serum levels of inflammatory factors and MMP13. RESULTS In multivariable analyses, serum MMP13 was negatively associated with cartilage volume at patellar site (β: -32.94 mm3 per 10 ng/ml, P < 0.05), and positively associated with cartilage defect at medial femoral site (OR: 1.13 per 10 ng/ml, P < 0.05). Also, MMP13 was positively associated with K-L grading and IPFP signal intensity alteration (OR: 1.14 and 1.15 per 10 ng/ml, respectively, both P < 0.05), and negatively associated with IPFP volume (β: -0.34 cm3 per 10 ng/ml, P < 0.05). Furthermore, serum level of adiponectin was negatively associated serum MMP13 quartiles (OR: 0.66 per 10 μg/ml, P < 0.05), and serum levels of tumor necrosis factor (TNF)-α, interleukin (IL)-8 and IL-18 were positively associated with serum MMP13 quartiles (ORs: 1.01-1.18 per 10 pg/ml, all P < 0.05). CONCLUSIONS Serum level of MMP13 was associated with knee structural abnormalities as well as serum inflammatory factors. These suggest that systemic MMP13 may play a role in knee OA, and could be regulated by inflammatory factors.

Abstract
AIMS The objective of this study was twofold: (i) to examine the effect of Clostridium butyricum on intestinal barrier function and (ii) to elucidate the mechanisms involved in enhanced intestinal barrier function. METHODS AND RESULTS Forty-eight weaned piglets were assigned randomly to either a basal diet or a C. butyricum-supplemented diet. On day 15, all pigs were orally challenged with enterotoxigenic Escherichia coli (ETEC) K88 or saline. Clostridium butyricum decreased serum diamine oxidase activity and d-lactic acid concentration, as well as increased intestinal tight junction proteins (ZO-1, claudin-3 and occludin) expression in ETEC K88-infected pigs. Moreover, C. butyricum decreased IL-1β and IL-18 levels in serum and gut, whereas it increased IL-10 levels. Furthermore, C. butyricum downregulated NLRP3 and caspase-1 expression in ETEC K88-challenged pig gut, but did not affect apoptosis-associated speck-like protein expression. CONCLUSIONS Clostridium butyricum enhanced intestinal barrier function and inhibited apoptosis-associated speck-like protein-independent NLRP3 inflammasome signalling pathway in weaned piglets after ETEC K88 challenge. SIGNIFICANCE AND IMPACT OF THE STUDY The novelty of this study lies in the beneficial effects of C. butyricum on intestinal health, likely by improving intestinal barrier function and alleviating inflammatory reactions.

Abstract
CONTEXT Endometrial insulin resistance (IR) may account for the endometrial dysfunction in polycystic ovary syndrome (PCOS). The underlying mechanism remains to be elucidated. OBJECTIVE To investigate whether the abundance of 11β-hydroxysteroid dehydrogenases (11β-HSDs) 1 and 2 and cortisol as well as the insulin signaling pathway are altered in PCOS endometrium and to clarify the relationship between endometrial IR and local cortisol. DESIGN We measured cortisol and cortisone concentrations, 11β-HSD1 and 11β-HSD2, and core insulin signaling molecules in endometrial biopsies collected from non-PCOS and PCOS with or without IR patients on the seventh day after human chorionic gonadotropin injection. We also studied the effects of cortisol on glucose uptake and the insulin signaling pathway in primary cultured endometrial epithelial cells (EECs). RESULTS The cortisol concentration was elevated, whereas 11β-HSD2 expression was diminished in endometrial biopsies obtained from PCOS with IR patients compared with those from non-PCOS and PCOS without IR patients. The implantation rate was relatively impaired and the endometrial insulin signaling pathway was defective in PCOS with IR patients. In addition, cortisol attenuated insulin-stimulated glucose uptake in EECs, which was mediated by inhibition of Akt phosphorylation and glucose transporter type 4 translocation via induction of phosphatase and tensin homolog deleted on chromosome ten (PTEN). CONCLUSIONS Decreased oxidation of cortisol and defects of insulin signaling in endometrium were observed in PCOS with IR patients. The excessive cortisol level, derived from the reduction of 11β-HSD2, might contribute to the development of endometrial IR by inhibiting the insulin signaling pathway via induction of PTEN expression in EECs.

Abstract
BACKGROUND Use of the immune checkpoint inhibitor ipilimumab is sometimes complicated by ipilimumab-associated colitis (Ipi-AC), an immune-mediated colitis that mimics inflammatory bowel disease. OBJECTIVE We sought to characterize the histopathologic and immunophenotypic features of Ipi-AC and to directly compare these features to ulcerative colitis (UC). METHODS This is a retrospective cohort study of 22 patients with Ipi-AC, 12 patients with treatment-naïve UC and five controls with diarrhoea but normal endoscopic findings. Immunohistopathologic features were described, and quantitative immunohistochemistry (IHC) was performed for CD4, CD8, CD20, CD138 and FOXP3. RESULTS Endoscopic findings in both the Ipi-AC and UC groups included ulcerated, oedematous and erythematous mucosa. Involvement of the GI tract was more diffuse in Ipi-AC. As compared to UC, a smaller proportion of Ipi-AC biopsies had basal plasmacytosis (14% for Ipi-AC vs. 92% for UC, P < 0.0001) and crypt distortion (23% for Ipi-AC vs. 75% for UC, P = 0.003), whereas Ipi-AC biopsies had more apoptotic bodies in the left colon (17.6 ± 15.3 for Ipi-AC vs. 8.2 ± 4.2 for UC, P = 0.011). Cryptitis, ulcerations and crypt abscesses were common in both groups. Biopsy specimens from Ipi-AC had a lower density of CD20-positive lymphocytes than UC (275.8 ± 253.3 cells mm-2 for Ipi-AC vs. 1173.3 ± 1158.2 cells mm-2 for UC, P = 0.022) but had a similar density of CD4, CD8, CD138 and FOXP3-positive cells. CONCLUSIONS Ipi-AC is a distinct pathologic entity with notable clinical and histopathological differences compared to UC. These findings provide insights into the pathophysiology of immune-related adverse events (iAEs) from ipilimumab therapy.

Abstract
We report a computational discovery of novel grain boundary structures and multiple grain boundary phases in elemental body-centered cubic (bcc) metals represented by tungsten, tantalum and molybdenum. While grain boundary structures created by the γ-surface method as a union of two perfect half crystals have been studied extensively, it is known that the method has limitations and does not always predict the correct ground states. Herein, we use a newly developed computational tool, based on evolutionary algorithms, to perform a grand-canonical search of high-angle symmetric tilt and twist boundaries, and we find new ground states and multiple phases that cannot be described using the conventional structural unit model. We use molecular dynamics (MD) simulations to demonstrate that the new structures can coexist at finite temperature in a closed system, confirming that these are examples of different grain boundary phases. The new ground state is confirmed by first-principles calculations.

Abstract
Objective: To investigate the sleep quality and related determinants among centenarians in Hainan. Methods: A cross-sectional study of centenarians from 16 cities/counties was carried out in Hainan province between June 2014 and June 2016. Data related to demography, chronic diseases and lifestyles of the centenarians were collected. Pittsburg sleep quality index (PSQI) was used to assess the quality of sleep while multivariable logistic Regression model was used to determine the risk factors on the quality of sleep. Results: Of the 730 centenarians in this study, 225 suffered from sleep disorders (30.8%). The average score of PSQI was (6.44±3.05), with the top three problems related to sleep as sleep inefficiency (48.5%), sleep latency (35.5%), and daytime dysfuntion (20.6%) among the centenarians. Results from the multivariate logistic analysis showed that incontinence, cardiovascular disease and chronic pain were risk factors, while habitual afternoon nap, and regular diet appeared as protective factors (P<0.05), related to sleep disorder. Conclusions: Quality of sleep had been a problem to the centenarians in Hainan. Intervention on risk factors of sleep disorder should be helpful on these centenarians.

Abstract
Approximately 40% of middle‐aged men exhibit symptoms of late‐onset hypogonadism (LOH). However, the mechanism of androgen deficiency is still currently unclear. As shown in our previous studies, the SET protein is expressed in testicular Leydig cells and ovarian granule cells. This study was designed to investigate the effect of the SET protein on androgen production in Leydig cells. The AdCMV/SET and AdH1siRNA/SET adenoviruses were individually transduced into a cultured mouse Leydig cell line (mLTC‐1) with or without human chorionic gonadotropin (HCG) stimulation in vitro. The primary mouse Leydig cells were used to confirm the main data from mLTC‐1 cells. The SET protein was expressed in the cytoplasm and nucleus of mLTC‐1 cells. Testosterone production was significantly increased in mLTC‐1 cells overexpressing the SET protein compared with the control group (p < 0.05), whereas testosterone production was significantly decreased in the SET knockdown mLTC‐1 cells (p < 0.05). Consistent with the testosterone levels, the expression levels of the steroidogenic acute regulatory (StAR) and cytochrome P450c17α‐hydroxylase (CYP17a1) mRNAs and proteins synchronously changed according to the expression level of the SET protein. Interestingly, the expression of the SET protein was significantly increased in the mLTC‐1 cells stimulated with 0.04 and 0.1 U/mL hCG. In the mLTC‐1 cells transfected with AdH1siRNA/SET and concurrently stimulated with 0.1 U/mL hCG, both testosterone production and StAR expression were significantly lower than in the cells without SET knockdown (p < 0.05). In conclusion, the SET protein participates in regulating testosterone production by increasing the expression of StAR and CYP17a1, and it may be a downstream factor of the classic luteinizing hormone (LH)/luteinizing hormone receptor (LHR) signaling pathway. This study improves our understanding of the intracellular mechanism of testicular steroidogenesis and the pathophysiological mechanism of LOH in the aging male.

Abstract
BACKGROUND Conventional criteria for tumor progression may not fully reflect the clinical benefit of immunotherapy or appropriately guide treatment decisions. The phase II IMvigor210 study demonstrated the efficacy and safety of atezolizumab, a programmed death-ligand 1-directed antibody, in patients with platinum-treated locally advanced or metastatic urothelial carcinoma. Patients could continue atezolizumab beyond Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 progression at the investigator's discretion: this analysis assessed post-progression outcomes in these patients. PATIENTS AND METHODS Patients were treated with atezolizumab 1200 mg i.v. every 3 weeks until loss of clinical benefit. Efficacy and safety outcomes in patients who experienced RECIST v1.1 progression and did, or did not, continue atezolizumab were analyzed descriptively. RESULTS In total, 220 patients who experienced progression from the overall cohort (n = 310) were analyzed: 137 continued atezolizumab for ≥ 1 dose after progression, 19 received other systemic therapy, and 64 received no further systemic therapy. Compared with those who discontinued, patients continuing atezolizumab beyond progression were more likely to have had a baseline Eastern Cooperative Oncology Group performance status of 0 (43.1% versus 31.3%), less likely to have had baseline liver metastases (27.0% versus 41.0%), and more likely to have had an initial response to atezolizumab (responses in 11.7% versus 1.2%). Five patients (3.6%) continuing atezolizumab after progression had subsequent responses compared with baseline measurements. Median post-progression overall survival was 8.6 months in patients continuing atezolizumab, 6.8 months in those receiving another treatment, and 1.2 months in those receiving no further treatment. Atezolizumab exposure-adjusted adverse event frequencies were generally similar before and following progression. CONCLUSION In this single-arm study, patients who continued atezolizumab beyond RECIST v1.1 progression derived prolonged clinical benefit without additional safety signals. Identification of patients most likely to benefit from atezolizumab beyond progression remains an important challenge in the management of metastatic urothelial carcinoma.

Abstract
The proinflammatory cytokine interleukin-1β (IL-1β) may be involved in several ovulation-associated events, such as protease synthesis, prostaglandin production, and steroidogenesis in granulosa cells. However, the exact effect of IL-1β on progesterone synthesis in granulosa cells and the underlying mechanism remain unclear. By using cultured granulosa-lutein cells collected from women undergoing in vitro fertilization or intracytoplasmic sperm injection, we found that IL-1β upregulated steroidogenic acute regulatory protein (StAR) expression and progesterone synthesis in granulosa-lutein cells, which was comparable with luteinizing hormone effect and could be abolished by an IL-1 receptor antagonist. Moreover, IL-1β activated the phosphorylation of cyclic adenosine monophosphate response element-binding protein (CREB), and knockdown of CREB attenuated the induction of StAR expression and progesterone synthesis by IL-1β in granulosa-lutein cells. Furthermore, IL-1β activated the extracellular signal-regulated kinase (ERK)1/2 and p38 pathways and inhibition of the ERK1/2 and p38 pathways attenuated the IL-1β-induced phosphorylation of CREB, StAR expression, and progesterone synthesis in granulosa-lutein cells. In conclusion, IL-1β could upregulate StAR expression and stimulate progesterone biosynthesis through increase in CREB phosphorylation via activating the ERK1/2 and p38 pathways in human granulosa-lutein cells.

Abstract
Osteoarthritis (OA) as a debilitating affliction of joints currently affects millions of people and remains an unsolved problem. The disease involves multiple cellular and molecular pathways that converge on the progressive destruction of cartilage. Activation of cartilage regenerative potential and specific targeting pathogenic mediators have been the major focus of research efforts aimed at slowing the progression of cartilage degeneration and preserve joint function. This review will summarize recent key discoveries toward better understanding of the complex mechanisms behind OA development and highlight the latest advances in basic and clinical research in the approach for cartilage regeneration. Prospectively, more potent therapeutic strategies against progressive cartilage deterioration may use a combination of cytotherapy, pharmacotherapy, and bioscaffoldings for improved chondrogenic differentiation and stem/progenitor cell homing as well as the concomitant reduced enzymatic matrix degradation and inflammation. Further, treatments need to be provided with increased preciseness of targeted therapy. One might expect that the regenerative therapies could potentially control or even possibly cure OA if performed at early stages of the disease.

Abstract
OBJECTIVE The roles of ghrelin in knee osteoarthritis (OA) are unclear. This study aimed to examine cross-sectional associations of ghrelin with knee symptoms, joint structures and cartilage or bone biomarkers in patients with knee OA. METHODS This study included 146 patients with symptomatic knee OA. Serum levels of ghrelin and cartilage or bone biomarkers including cartilage oligomeric matrix protein (COMP), cross linked C-telopeptide of type I collagen (CTXI), cross linked N-telopeptide of type I collagen (NTXI), N-terminal procollagen III propeptide (PIIINP), and matrix metalloproteinase (MMP)-3, 10, 13 were measured using Enzyme-linked immunosorbent assay (ELISA). Knee symptoms were assessed using the Western Ontario and McMaster Universities Arthritis Index (WOMAC). Infrapatellar fat pad (IPFP) volume, IPFP signal intensity alternation, cartilage defects, bone marrow lesions (BMLs) and effusion-synovitis were assessed using the (MRI). Osteophytes and joint space narrowing (JSN) were assessed using the Osteoarthritis Research Society International atlas. RESULTS After adjustment for potential confounders, ghrelin quartiles were positively associated with knee symptoms including pain, stiffness, dysfunction and total score (quartile 4 vs 1: β 24.19, 95% CI 8.13-40.25). Ghrelin quartiles were also significantly associated with increased IPFP signal intensity alteration (quartile 4 vs 1: OR 3.57, 95% CI 1.55-8.25) and NTXI, PIIINP, MMP3 and MMP13. Ghrelin was not significantly associated with other joint structures and biomarkers. CONCLUSIONS Serum levels of ghrelin were significantly associated with increased knee symptoms, IPFP signal intensity alteration and serum levels of MMP3, MMP13, NTXI and PIIINP, suggesting that ghrelin may have a role to play in knee OA.

Abstract
Objective: To investigate the expression of long non-coding RNA (lncRNA) SNHG8 in EB virus related gastric cancer and their correlation prognosis. Methods: The expression of SNHG8 in 93 gastric cancers and 93 cancer-free controls, matched by age and sex, were determined by real-time PCR. EB virus expression was detected by EBER in situ hybridization. Results: Forty-one gastric cancers were EB virus associated. For all gastric cancers, SNHG8 expression was 14 times higher (P=0.001) than that in non-cancer controls; in the EB virus related gastric cancers, SNHG8 expression was increased 25 times (P<0.05) over EB virus negative gastric cancers. SNHG8 expression level was also significantly associated with TNM staging (P<0.05). Conclusions: SNHG8 may act as a proto-oncogene, participating in gastric carcinogenesis.EB virus infection of gastric mucosa may promote SNHG8 expression.

Abstract
Rheumatoid arthritis (RA) is a chronic immune inflammatory disease mediated by the influx of immune cells into the synovial joint space. As Tanshinone IIA (TIIA) has potent anti-oxidant and anti-inflammatory activities, we used the adjuvant-induced arthritis (AA) murine model of RA to investigate the impact of TIIA on RA and immune cell activation. The anti-arthritic activity of TIIA was investigated in an adjuvant-induced arthritis model of RA in mice. Myeloperoxidase and neutrophil elastase expression levels were assessed in ankle joints by immunohistochemistry analysis. Immune cell infiltration was evaluated in air pouch experiments. Proinflammatory cytokines expression levels were determined by quantitative real-time polymerase chain reaction (PCR) and enzyme-linked immunosorbent assays. Neutrophil extracellular traps (NETs) were assessed by immunostaining and confocal microscopy. Treatment with TIIA alleviated cartilage erosion and neutrophil infiltration in the ankle joints of AA mice and reduced proinflammatory cytokine expression levels in sera. TIIA suppressed interleukin-6 and tumour necrosis factor-α expression and release in neutrophils and promoted neutrophil apoptosis. TIIA also inhibited the NET formation of neutrophils. Our findings demonstrated that TIIA can ameliorate RA effectively by targeting neutrophils, indicating that TIIA may act as a potential therapeutic for RA.

Abstract
OBJECTIVE To investigate HIV-1 subtype diversity and the frequency of primary drug resistance in newly confirmed HIV infections/AIDS, and the ratio of recently infected cases in Henan. METHODS Newly confirmed HIV infections/AIDS from June 2013 to October 2013 and from June 2014 to October 2014 in the municipal CDC and county CDC of six cities in Henan province (Nanyang, Luohe, Pingdingshan, Shangqiu, Xuchang and Zhengzhou) were included in this study. Information on demographics, route of infection and antiviral therapy regimen were obtained from report cards, and at follow-up visits. After collection of blood samples from 402 individuals for confirmatory diagnostic tests, 100 were excluded because of hemolysis or insufficient samples in 11 cases, and incomplete amplification results in 89 cases. Recent HIV infection was determined by the BED capture immunoassay. An in-house method were used for genotypic drug resistance tests and sequence analysis. RESULTS Among the 302 individuals included, the mean age was (44.0±15.5) years, and 160 (53.0%) and 142 (47.0%) cases were confirmed in 2013 and 2014, respectively. The ratio of recent infections was 29.5% (89 cases), inside, the ratio of recent infections were 31.3% (20/64), 40.5% (30/74), 21.3% (32/150), 3/8 and 4/6 in 01_AE, 07_BC, B, 01_B and other subtypes (B/C, C, 01_BC and 08_BC) (χ(2)=13.48, P=0.009). The frequency of the B subtype was higher in former infections, at 55.4% (118/213), than in recent infections, at 36% (32/89) (χ(2)=9.49, P=0.002). In contrast, the ratios of both 07_BC and other subtypes were lower in former infections (20.7% (44/213) and 1% (2/213), respectively) than recent infections (33.7% (30/89), χ(2)=5.78, P=0.016 and 5% (4/89), χ(2)=4.08; P=0.044, respectively). The frequency of primary HIV-1 drug resistance was 6.0% (18 cases) in 302 subjects. The frequency of resistance to nucleoside reverse transcriptase inhibitor (NRTI) and non-nucleoside reverse transcriptase inhibitor (NNRTI) drugs was 2.7% (8 cases) and 3.6% (11 cases), respectively. Primary HIV-1 drug resistance was more frequent in subtypes B and 07_BC, at 8.7% (13 cases) and 5.4% (4 cases), respectively. CONCLUSION Newly confirmed HIV infections/AIDS in Henan province harbored certain proportion of none-B subtypes, the frequency of primary resistance tended to be high in HIV-1B infection. The molecular epidemiology of HIV and the development of primary drug resistance should be regularly monitored.

Abstract
Objective: To investigate the current bedtime routine among Chinese children less than 3 years of age and explore its dose-dependent association with sleep duration and sleep quality. Method: Healthy full-term born children aged 0-35 months were selected by stratified cluster random sampling method from 8 provinces in China following the "Hospital of Province-City-County" sampling technical route during 2012-2013.Brief Infant Sleep Questionnaire(BISQ) was used to assess sleep conditions of these children.Children's personal and family information was obtained by Shanghai Children's Medical Center Socio-demographic Questionnaire.Both of these questionnaires were filled in by parents. The effects of bedtime routine on children's sleep duration and quality were analyzed by multivariate analysis of variance. Result: The children's average age was(12±10) months(n=1 304), of whom 689 were males (52.8%, 689/1 304). There were 48.5%(632/1 304)of the parents reported that their children had not established regular sleep routines. There was a consistent dose-dependent association between bedtime routine and sleep duration, as well as other indicators for sleep quality (all P<0.05). The more regular the sleep routines, the longer the sleep duration, the earlier the children went to sleep, the shorter the sleep onset latency, the fewer the nighttime wakeup and the shorter the nighttime waking.The nighttime sleep duration was significantly longer for those with a bedtime routine 'every night' than those who 'never' had a bedtime routine (9.5(95%CI: 9.4-9.6)vs. 8.9(95%CI: 8.6-9.3)h, t=3.345, P=0.001). Compared with children who never had bedtime routines, children with regular bedtime routines had fewer night wakeup (1.3(95%CI: 1.2-1.4) vs. 2.4( 95%CI: 2.0-2.9), t=3.182, P=0.001) and shorter night waking duration(16.6(95%CI: 14.6-18.8) vs. 59.2 (95%CI: 47.0-72.7)min, t=6.383, P<0.01). Conclusion: The percentage of children who have established regular bedtime routine is low in China. There is significant dose-dependent association between regular bedtime routine and sleep outcomes, especially sleep quality. The more regular the sleep routines, the better the sleep quality.
