3Astragalus extract inhibits destruction of gastric cancer cells to mesothelial cells by anti-apoptosis显示文摘AIM: To determine the inhibitory effect of Astragalus memebranaceushas on gastric cancer cell supernatantinduced apoptosis of human peritoneal mesothelial cells. METHODS: Human peritoneal mesothelial cell (HPMC) line HMrSV5 was co-incubated with gastric cancer cell supernatant (MKN45) and/or Astragalus memebranaceushas. Morphological changes in gastric cancer cells were observed under phase-contrast microscope. Quantitative cell damage was determined by MTT assay. Apoptosis was determined under transmission electron microscope and quantified by detecting acridine orange/ethidium bromide-stained (AO/EB) condensed nuclei under fluorescent microscope or by flow cytometry. Expressions of Bcl-2 and Bax were evaluated with immunostaining. RESULTS: Morphological changes and exfoliation occurred and naked areas appeared in cultured HMrSV5 cells 24 h after they were treated with gastric cancer cell supernatant. Cell supernatant from MKN45 gastric cancer cells induced apoptosis of HMrSV5 cells in a time-dependent manner. Obvious morphological changes were observed in cell apoptosis, such as condensation of chromatin, nuclear fragmentations and apoptotic bodies. Astragalus memebranaceus could partly suppress these changes and regulate the expressions of Bcl-2 and Bax in HMrSV5 cells.CONCLUSION: Gastric cancer cells induce apoptosis of HPMCs through the supernatant. Astragalus memebranaceushas inhibits this phenomenon and can be used an adjuvant chemothera-peutic agent in gastric cancer therapy.Di Na Fu-Nan Liu Zhi-Feng Miao Zong-Min Du Hui-Mian Xu 2009World Journal of Gastroenterology2009,15,5:17

6Serum Uric Acid is Associated with the Predicted Risk of Prevalent Cardiovascular Disease in a Community-dwelling Population without Diabetes显示文摘Objective To examine the association between serum uric acid levels and cardiovascular disease risk among individuals without diabetes. Methods We investigated the association between serum uric acid levels and the risk of prevalent cardiometabolic diseases, 10-year Framingham risk for coronary heart disease, and 10-year risk for atherosclerotic cardiovascular diseases(ASCVD) among 8,252 participants aged ≥ 40 years without diabetes from Jiading district, Shanghai, China. Results Body mass index, waist circumference, blood glucose, glycated hemoglobin, blood pressure, and serum lipids increased progressively across the sex-specific quartiles of uric acid(all P trend < 0.05). Compared with individuals in the lowest quartile, those in the higher quartiles had a significantly higher prevalence of obesity, hypertension, and dyslipidemia(all P trend < 0.05). A fully adjusted logistic regression analysis revealed that individuals in the highest quartile had an increased risk of predicted cardiovascular disease compared with those in the lowest quartile of uric acid. The multivariate adjusted odds ratios(ORs) [95% confidence intervals(CIs)] for the highest quartiles for high Framingham risk were 3.00(2.00-4.50) in men and 2.95(1.08-8.43) in women. The multivariate adjusted ORs(95% CIs) for the highest quartile for high ASCVD risk were 1.93(1.17-3.17) in men and 4.53(2.57-7.98) in women. Conclusion Serum uric acid level is associated with an increased risk of prevalent obesity, hypertension, dyslipidemia, 10-year Framingham risk for coronary heart disease, and 10-year risk for ASCVD among Chinese adults without diabetes.CHENG Di DU Rui WU Xue Yan LIN Lin PENG Kui MA Li Na XU Yu XU Min CHEN Yu Hong BI Yu Fang WANG Wei Qing DAI Meng LU Jie Li 2018Biomedical and Environmental Sciences2018,31,2:13

8Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12

10Single-cell RNA sequencing reveals atlas of dairy goat testis cells显示文摘Single-cell RNA sequencing(scRNA-seq)is useful for exploring cell heterogeneity.For large animals,however,little is known regarding spermatogonial stem cell(SSC)selfrenewal regulation,especially in dairy goats.In this study,we described a high-resolution scRNA-seq atlas derived from a dairy goat.We identified six somatic cell and five spermatogenic cell subtypes.During spermatogenesis,genes with significantly changed expression were mainly enriched in the Notch,TGF-β,and Hippo signaling pathways as well as the signaling pathway involved in the regulation of stem cell pluripotency.We detected and screened specific candidate marker genes(TKTL1 and AES)for spermatogonia.Our study provides new insights into goat spermatogenesis and the development of testicular somatic cells.Xiu-Wei Yu Tong-Tong Li Xiao-Min Du Qiao-Yan Shen Meng-Fei Zhang Yu-Dong Wei Dong-Hui Yang Wen-Jing Xu Wen-Bo Chen Chun-Ling Bai Xue-Ling Li Guang-Peng Li Na Li Sha Peng Ming-Zhi Liao Jin-Lian Hua 2021Zoological Research2021,42,4:9
11Supplemental magnolol or honokiol attenuates adverse effects in broilers infected with Salmonella pullorum by modulating mucosal gene expression and the gut microbiota显示文摘Background:Salmonella pullorum is one of the most harmful pathogens to avian species.Magnolol and honokiol,natural compounds extracted from Magnolia officinalis,exerts anti-inflammatory,anti-oxidant and antibacterial activities.This study was conducted to evaluate the effects of dietary supplemental magnolol and honokiol in broilers infected with S.pullorum.A total of 360 one-day-old broilers were selected and randomly divided into four groups with six replicates:the negative control group(CTL),S.pullorum-infected group(SP),and the S.pulloruminfected group supplemented with 300 mg/kg honokiol(SPH)or magnolol(SPM).Results:The results showed that challenging with S.pullorum impaired growth performance in broilers,as indicated by the observed decreases in body weight(P<0.05)and average daily gains(P<0.05),along with increased spleen(P<0.01)and bursa of Fabricus weights(P<0.05),serum globulin contents,and the decreased intestine villus height and villus/crypt ratios(P<0.05).Notably,supplemental magnolol and honokiol attenuated these adverse changes,and the effects of magnolol were better than those of honokiol.Therefore,we performed RNA-Seq in ileum tissues and 16S rRNA gene sequencing of ileum bacteria.Our analysis revealed that magnolol increased the α-diversity(observed species,Chao1,ACE,and PD whole tree)and β-diversity of the ileum bacteria(P<0.05).In addition,magnolol supplementation increased the abundance of Lactobacillus(P<0.01)and decreased unidentified Cyanobacteria(P<0.05)both at d 14 and d 21.Further study confirmed that differentially expressed genes induced by magnolol and honokiol supplementation enriched in cytokine-cytokine receptor interactions,in the intestinal immune network for IgA production,and in the cell adhesion molecule pathways.Conclusions:Supplemental magnolol and honokiol alleviated S.pullorum-induced impairments in growth performance,and the effect of magnolol was better than that of honokiol,which could be partially due to magnolol’s ability to improve the intestinal microbial and mucosal barrier.Fang Chen Hao Zhang Encun Du Qiwen Fan Na Zhao Feng Jin Wei Zhang Wanzheng Guo Shaowen Huang Jintao Wei 2022Journal of Animal Science and Biotechnology2022,13,1:9
12Strengths, weaknesses, opportunities and threats (SWOT) analysis of reinitiation into methamphetamine abusers: qualitative findings from an exploration of methamphetamine abusers in Shanghai, China显示文摘Background Despite high relapse rate among methamphetamine (MA) abusers, there still have been little empirical data to date detecting the risk factors related to craving and relapse from the perspective of MA abusers. Therefore, the aim of this study was to use qualitative research methods exploring the strengths, weaknesses, opportunities and threat factors that could facilitate or impede individuals' abstinence in a real-life context from the perspectives of MA abusers. Aim To use qualitative research methods exploring the strengths, weaknesses, opportunities and threat factors relating to individuals' abstinence in a real-life context. Method Semistructured interviews were conducted with 32 MA abusers recruited in Shanghai guided by open-ended questions on narrating the real-life catalysts and inhibitors related to craving, initiation, relapse and abstinence. All data were transcribed verbatim and analysed using a strengths, weaknesses, opportunities and threats (SWOT) analysis. Results The results of the SWOT analysis revealed that contextual factors including peer influence, prevalence and availability of MA, familiar venue of MA use, discrimination, sexual behaviours, alcohol, emotional states and their attitudes towards smoking MA were important factors that contribute to reinitiation and relapse. Surveillance systems, antidrug social workers, vocational skills trainings, moving to another city and family responsibility might serve as counter measures targeti叩 those mentioned weaknesses and threats above. Conclusion This SWOT analysis highlights the complex nature of relapse. Comprehensive interventions strengtheni叩 coping skills such as virtual reality techniques are desperately needed to facilitate individuals1 sustained abstinence.Youwei Zhu Na Zhong Hang Su Xiaolu Ruan Jiayi Bao Lei Zhang Jiang Du Ding Xu Rongjie Ding Ke Xiao Min Zhao 2019General Psychiatry2019,32,3:9
13Sensitivity studies of a high accuracy surface modeling method显示文摘The sensitivities of the initial value and the sampling information to the accuracy of a high accuracy surface modeling(HASM) are investigated and the implementations of this new modeling method are modified and enhanced. Based on the fundamental theorem of surface theory, HASM is developed to correct the error produced in geographical information system and ecological modeling process. However, the earlier version of HASM is theoretically incomplete and its initial value must be produced by other surface modeling methods, such as spline, which limit its promotion. In other words, we must use other interpolators to drive HASM. According to the fundamental theorem of surface theory, we modify HASM, namely HASM.MOD, by adding another important nonlinear equation to make it independent of other methods and, at the same time, have a complete and solid theory foundation. Two mathematic surfaces and monthly mean temperature of 1951–2010 are used to validate the effectiveness of the new method. Experiments show that the modified version of HASM is insensitive to the selection of initial value which is particular important for HASM. We analyze the sensitivities of sampling error and sampling ratio to the simulation accuracy of HASM.MOD. It is found that sampling information plays an important role in the simulation accuracy of HASM.MOD. Another feature of the modified version of HASM is that it is theoretically perfect as it considers the third equation of the surface theory which reflects the local warping of the surface. The modified HASM may be useful with a wide range of spatial interpolation as it would no longer rely on other interpolation methods.ZHAO Na YUE TianXiang ZHAO MingWei DU ZhengPing FAN ZeMeng CHEN ChuanFa 2014Science China Earth Sciences2014,57,10:9

15A fundamental theorem for eco-environmental surface modelling and its applications显示文摘We propose a fundamental theorem for eco-environmental surface modelling(FTEEM) in order to apply it into the fields of ecology and environmental science more easily after the fundamental theorem for Earth’s surface system modeling(FTESM). The Beijing-Tianjin-Hebei(BTH) region is taken as a case area to conduct empirical studies of algorithms for spatial upscaling, spatial downscaling, spatial interpolation, data fusion and model-data assimilation, which are based on high accuracy surface modelling(HASM), corresponding with corollaries of FTEEM. The case studies demonstrate how eco-environmental surface modelling is substantially improved when both extrinsic and intrinsic information are used along with an appropriate method of HASM. Compared with classic algorithms, the HASM-based algorithm for spatial upscaling reduced the root-meansquare error of the BTH elevation surface by 9 m. The HASM-based algorithm for spatial downscaling reduced the relative error of future scenarios of annual mean temperature by 16%. The HASM-based algorithm for spatial interpolation reduced the relative error of change trend of annual mean precipitation by 0.2%. The HASM-based algorithm for data fusion reduced the relative error of change trend of annual mean temperature by 70%. The HASM-based algorithm for model-data assimilation reduced the relative error of carbon stocks by 40%. We propose five theoretical challenges and three application problems of HASM that need to be addressed to improve FTEEM.Tianxiang YUE Na ZHAO Yu LIU Yifu WANG Bin ZHANG Zhengping DU Zemeng FAN Wenjiao SHI Chuanfa CHEN Mingwei ZHAO Dunjiang SONG Shihai WANG Yinjun SONG Changqing YAN Qiquan LI Xiaofang SUN Lili ZHANG Yongzhong TIAN Wei WANG Ying’an WANG Shengnan MA Hongsheng HUANG Yimin LU Qing WANG Chenliang WANG Yuzhu WANG Ming LU Wei ZHOU Yi LIU Xiaozhe YIN Zong WANG Zhengyi BAO Miaomiao ZHAO Yapeng ZHAO Yimeng JIAO Ufra NASEER Bin FAN Saibo LI Yang YANG John PWILSON 2020Science China Earth Sciences2020,63,8:7
16Effectiveness of Dinoprostone and Cook's Balloon for Labor Induction in Primipara Women at Term显示文摘Labor induction is commonly used for achieving successful vaginal delivery.This study aimed to compare the effectiveness of dinoprostone and Cook's balloon as labor-inducing agents in primipara women at term.A retrospective cohort study among primipara women was conducted in Hubei Maternity and Child Health Hospital.Basic clinical characteristics were collected.The main outcomes were vaginal delivery rate,cesarean section rate and forceps delivery rate.Obstetric and perinatal outcomes were also compared.Univariate and multivariate analyses were further performed to evaluate the predictors for vaginal delivery within 24 h.A total of 845 eligible primipara women undergoing labor induction were recruited.Of them,141 women were induced with dinoprostone(dinoprostone group,DG),and 704 with Cook's balloon(Cook's balloon group,CG).Groups were homogeneous except more women with premature rupture of membranes in DG,with gestational hypertension in CG(P<0.05).The vaginal delivery rate within 12 h was 1.98%and 16.52%in CG and DG respectively(P=0.0001).Besides,the vaginal delivery rate within 24 h was 37.62%and 52.26%in CG and DG respectively(P=0.0079).DG showed the lower rate of oxytocin augmentation,artificial rupture of membrane and postpartum hemorrhage and the shorter interval from insertion to active labor than CG(P<0.05).Multivariate regression analysis revealed that abortion history,oxytocin augmentation,artificial rupture of membrane,and obstric analgesia were independent predictors for vaginal delivery within 24 h.In conclusion,dinoprostone was more effective than Cook's balloon to induce labor and achieve vaginal birth in the sample of primipara women at term.Hui DU Na ZHANG Chan-yun XIAO Guo-qiang SUN Yun ZHAO 2020Current Medical Science2020,40,5:7
17IL-17 sustains the plasma cell response via p38-mediated Bcl-xL RNA stability in lupus pathogenesis显示文摘Recent studies have demonstrated a central role for plasma cells in the development of autoimmune diseases,such as systemic lupus erythematosus(SLE).Currently,both the phenotypic features and functional regulation of autoreactive plasma cells during SLE pathogenesis remain largely unclear.In this study,we first found that a major subset of IL-17 receptor-expressing plasma cells potently produced anti-dsDNA IgG upon IL-17A(IL-17)stimulation in SLE patients and lupus mice.Using a humanized lupus mouse model,we showed that the transfer of Th17 cell-depleted PBMCs from lupus patients resulted in a significantly reduced plasma cell response and attenuated renal damage in recipient mice compared to the transfer of total SLE PBMCs.Moreover,long-term BrdU incorporation in lupus mice detected highly enriched long-lived BrdU+subsets among IL-17 receptor-expressing plasma cells.Lupus mice deficient in IL-17 or IL-17 receptor C(IL-17RC)exhibited a diminished plasma cell response and reduced autoantibody production with attenuated renal damage,while the adoptive transfer of Th17 cells triggered the plasma cell response and renal damage in IL-17-deficient lupus mice.In reconstituted chimeric mice,IL-17RC deficiency resulted in severely impaired plasma cell generation but showed no obvious effect on germinal center B cells.Further mechanistic studies revealed that IL-17 significantly promoted plasma cell survival via p38-mediated Bcl-xL transcript stabilization.Together,our findings identified a novel function of IL-17 in enhancing plasma cell survival for autoantibody production in lupus pathogenesis,which may provide new therapeutic strategies for the treatment of SLE.Kongyang Ma Wenhan Du Fan Xiao Man Han Enyu Huang Na Peng Yuan Tang Chong Deng Lixiong Liu Yulan Chen Jingjing Li Shiwen Yuan Qin Huang Xiaoping Hong Dajun Hu Xiaoyan Cai Quan Jiang Dongzhou Liu Liwei Lu 2021Cellular & Molecular Immunology2021,18,7:6
18Circulating MicroRNAs as Novel Diagnostic Biomarkers for Very Early-onset(≤40 years) Coronary Artery Disease显示文摘Objective Very early-onset coronary artery disease(CAD) is a great challenge in cardiovascular medicine throughout the world,especially regarding its early diagnosis.This study explored whether circulating micro RNAs(mi RNAs) could be used as potential biomarkers for patients with very early-onset CAD.Methods We performed an initial screening of mi RNA expression using RNA isolated from 20 patients with angiographically documented very early-onset CAD and 20 age-and sex-matched normal controls.For further confirmation,we prospectively examined the mi RNAs selected from 40 patients with very early-onset CAD and 40 angiography-normal controls.Results A total of 22 overexpressed mi RNAs and 22 underexpressed mi RNAs were detected in the initial screening.RT-q PCR analysis of the mi RNAs obtained from the initial screening revealed that four mi RNAs including mi R-196-5p,mi R-3163-3p,mi R-145-3p,and mi R-190a-5p exhibited significantly decreased expression in patients compared with that in controls(P<0.05).The areas under the receiver operating characteristic curve for these mi RNAs were 0.824(95% CI,0.731-0.917;P<0.001),0.758(95% CI,0.651-0.864;P<0.001),0.753(95% CI,0.643-0.863;P<0.001),and 0.782(95% CI,0.680-0.884;P<0.001),respectively,in the validation set.Conclusion To our knowledge,this is an advanced study to report about four serum mi RNAs(mi R-196-5p,mi R-3163-3p,mi R-145-3p,and mi R-190a-5p) that could be used as novel biomarkers for the diagnosis of very early-onset CAD.DU Ying YANG Sheng Hua LI Sha CUI Chuan Jue ZHANG Yan ZHU Cheng Gang GUO Yuan Lin WU Na Qiong GAO Ying SUN Jing DONG Qian LIU Geng LI Jian Jun 2016Biomedical and Environmental Sciences2016,29,8:5
19Preparation of Electrospun PVDF Nanofiber Composite Filter Medium and Its Application in Air Filtration显示文摘Nanofibrous media with both high particle interception efficiency and robust air permeability has broad technological applications in areas including individual protection, industrial security, and environmental governance. However, producing such filtration media has proven to be extremely challenging. Here we reported an approach to preparing and fabricating a polyvinylidene fluoride (PVDF) nanofiber composite filter medium composed of 2D PVDF nanofiber nets and a stable substrate via onestep electrospinning for effective air filtration. PVDF nanofibers are obtained by adjusting the electrospinning process. With the combined properties of ultrasmall diameter, high porosity, and a bonded scaffold, the resulting PVDF nanofiber composite filter medium exhibits a robust high filtration efficiency of 99.901%(equivalent to an F9 rating) for 0.4 mm particles and a long service life (a large dust holding capacity of 36 g/m^2) for ultrafine airborne particles based on the sieving principle and surface filtration behavior. The successful synthesis of PVDF nanofibers medium would not only make it a promising candidate for air filtration, but also provide new insights into the design and development of composite nanofiber structures for various applications.Qi Du Na Wang Wen Liu XueFeng Chen Yue Xu Ying Wan 2019Paper And Biomaterials2019,4,1:5
