6Bone-marrow mesenchymal stem cells reduce rat intestinal ischemia-reperfusion injury, ZO-1 downregulation and tight junction disruption via a TNF-α-regulated mechanism显示文摘AIM: To investigate the effect of bone-marrow mesenchymal stem cells (BM MSCs) on the intestinal mucosa barrier in ischemia/reperfusion (I/R) injury. METHODS: BM MSCs were isolated from male Sprague-Dawley rats by density gradient centrifugation, cultured, and analyzed by flow cytometry. I/R injury was induced by occlusion of the superior mesenteric artery for 30 min. Rats were treated with saline, BM MSCs (via intramucosal injection) or tumor necrosis factor (TNF)-α blocking antibodies (via the tail vein). I/R injury was assessed using transmission electron microscopy, hematoxylin and eosin (HE) staining, immunohistochemistry, western blotting and enzyme linked immunosorbent assay.RESULTS: Intestinal permeability increased, tight junctions (TJs) were disrupted, and zona occludens 1 (ZO-1) was downregulated after I/R injury. BM MSCs reduced intestinal mucosal barrier destruction, ZO-1 downregulation, and TJ disruption. The morphological abnormalities after intestinal I/R injury positively correlated with serum TNF-α levels. Administration of anti-TNF-α IgG or anti-TNF-α receptor 1 antibodies attenuated the intestinal ultrastructural changes, ZO-1 downregulation, and TJ disruption. CONCLUSION: Altered serum TNF-α levels play an important role in the ability of BM MSCs to protect against intestinal I/R injury.Zhong-Yang Shen Jing Zhang Hong-Li Song Wei-Ping Zheng 2013World Journal of Gastroenterology2013,19,23:23

9Trends in particulate matter and its chemical compositions in China from 2013–2017显示文摘Accurate determination of the atmospheric particulate matter mass concentration and chemical composition is helpful in exploring the causes and sources of atmospheric enthalpy pollution and in evaluating the rationality of environmental air quality control strategies.Based on the sampling and chemical composition data of PM2.5 in different key regions of China in the CARE-China observation network,this research analyzes the environmental air quality data released by the China National Environmental Monitoring Centre during the studied period to determine the changes in the particulate matter mass concentration in key regions and the evolution of the corresponding chemical compositions during the implementation of the Action Plan for Prevention and Control of Air Pollution from 2013-2017.The results show the following.(1)The particulate matter mass concentration in China showed a significant downward trend;however,the PM2.5 annual mass concentration in 64%of cities exceeds the New Chinese Ambient Air Quality Standard(CAAQS)GradeⅡ(GB3095-2012).The region to the east of the Taihang Mountains,the Fenhe and Weihe River Plain and the Urumqi-Changji regions in Xinjiang,all have PM2.5 concentration loading that is still high,and heavy haze pollution occurred frequently in the autumn and winter.(2)During the heavy pollution in the autumn and winter,the concentrations of sulfate and organic components decreased significantly.The mean SO42-concentration in PM2.5 decreased by 76%,12%,81%and 38%in Beijing-Tianjin-Hebei(BTH),the Pearl River Delta(PRD),the Sichuan-Chongqing region(SC)and the Fenhe and Weihe River Plain,respectively.The mean organic matter(OM)concentration decreased by 70%,44%,48%and 31%,respectively,and the mean concentration of NH4+decreased by 68%,1.6%,38%and 25%,respectively.The mean elemental carbon(EC)concentration decreased by 84%and 20%in BTH and SC,respectively,and it increased by 61%and 11%in the PRD and Fenhe and Weihe River Plain,respectively.The mean concentration of mineral and unresolved chemical components(MI)dropped by 70%,24%and 13%in BTH,the PRD and the Fenhe and Weihe River Plain,respectively.The change in the PM2.5 chemical composition is consistent with the decrease of the PM2.5mass concentration.(3)In 2015,the mean OM concentration contributions to fine particles and coarse particles were 13-46%and 46-57%,respectively,and the mean MI concentration contributions to fine particles and coarse and particles were 31-60%and 39-73%,respectively;these values are lower than the 2013 values from the key regions,which is the most important factor behind the decrease of the particulate matter mass concentration.From 2013 to 2015,among the chemical components of different particle size fractions,the peak value of the coarse particle size fraction decreased significantly,and the fine particle size fractions of SO42-,NO3-,and NH4+decreased with the decrease of the particulate matter mass concentration in different particle size fractions.The fine-particle size peaks of SO42-,NO3-and NH4+shifted from 0.65-1.1μm to the finer size range of0.43-0.65μm during the same time frame.Yuesi WANG Wenjie LI Wenkang GAO Zirui LIU Shili TIAN Rongrong SHEN Dongsheng JI Shuai WANG Lili WANG Guiqian TANG Tao SONG Mengtian CHENG Gehui WANG Zhengyu GONG Jiming HAO Yuanhang ZHANG 2019Science China Earth Sciences2019,62,12:23
10The second natural gas hydrate production test in the South China Sea显示文摘Clayey silt reservoirs bearing natural gas hydrates(NGH)are considered to be the hydrate-bearing reservoirs that boast the highest reserves but tend to be the most difficult to exploit.They are proved to be exploitable by the first NGH production test conducted in the South China Sea in 2017.Based on the understanding of the first production test,the China Geological Survey determined the optimal target NGH reservoirs for production test and conducted a detailed assessment,numerical and experimental simulation,and onshore testing of the reservoirs.After that,it conducted the second offshore NGH production test in 1225 m deep Shenhu Area,South China Sea(also referred to as the second production test)from October 2019 to April 2020.During the second production test,a series of technical challenges of drilling horizontal wells in shallow soft strata in deep sea were met,including wellhead stability,directional drilling of a horizontal well,reservoir stimulation and sand control,and accurate depressurization.As a result,30 days of continuous gas production was achieved,with a cumulative gas production of 86.14×104 m3.Thus,the average daily gas production is 2.87×10^4 m^3,which is 5.57 times as much as that obtained in the first production test.Therefore,both the cumulative gas production and the daily gas production were highly improved compared to the first production test.As indicated by the monitoring results of the second production test,there was no anomaly in methane content in the seafloor,seawater,and atmosphere throughout the whole production test.This successful production test further indicates that safe and effective NGH exploitation is feasible in clayey silt NGH reservoirs.The industrialization of hydrates consists of five stages in general,namely theoretical research and simulation experiments,exploratory production test,experimental production test,productive production test,and commercial production.The second production test serves as an important step from the exploratory production test to experimental production test.Jian-liang Ye Xu-wen Qin Wen-wei Xie Hai-long Lu Bao-jin Ma Hai-jun Qiu Jin-qiang Liang Jing-an Lu Zeng-gui Kuang Cheng Lu Qian-yong Liang Shi-peng Wei Yan-jiang Yu Chunsheng Liu Bin Li Kai-xiang Shen Hao-xian Shi Qiu-ping Lu Jing Li Bei-bei Kou Gang Song Bo Li He-en Zhang Hong-feng Lu Chao Ma Yi-fei Dong Hang Bian 2020China Geology2020,3,2:22

12Current status of diagnosis and treatment of bladder cancer in China-Analyses of Chinese Bladder Cancer Consortium database显示文摘Objective:To investigate current status of diagnosis and treatment of bladder cancer in China.Methods:A database was generated by Chinese Bladder Cancer Consortium(CBCC).From January 2007 to December 2012,14,260 cases from 44 CBCC centers were included.Data of diagnosis,treatment and pathology were collected.Results:The average age was 63.5 year-old and most patients were male(84.3%).The most common histologic types were urothelial carcinoma(91.4%),adenocarcinoma(1.8%),and squamous carcinoma(1.9%).According to 1973 and 2004 WHO grading system,42.0%,41.0%,and 17.0% of patients were grade 1,2,and 3,and 16.0%,48.7%,and 35.3% of patients were papillary urothelial neoplasms of low malignant potential,low,and high grade,respectively.Non-muscle invasive bladder cancer(NMIBC)and muscle invasive bladder cancer(MIBC)were 25.2% and 74.1%,respectively(0.8% not clear).Carcinoma in situ was only 2.4%.Most patients were diagnosed by white-light cystoscopy with biopsy(74.3%).Fluorescence and narrow band imaging cystoscopy had additional detection rate of 1.0% and 4.0%,respectively.Diagnostic transurethral resection(TUR)provided detection rate of 16.9%.Most NMIBCs were treated with TUR(89.2%).After initial TUR,2.6%accepted second TUR,and 45.7%,69.9%,and 58.7% accepted immediate,induced,and maintenance chemotherapy instillation,respectively.Most MIBCs were treated with radical cystectomy(RC,59.7%).Laparoscopic RCs were 35.1%,while open RC 63.4%.Extended and standard pelvic lymph node dissection were 7% and 66%,respectively.Three most common urinary diversions were orthotopic neobladder(44%),ileal conduit(31%),and ureterocutaneostomy(23%).Only 2.3% of patients accepted neo-adjuvant chemotherapy and only 18%of T3 and T4 patients accepted adjuvant chemotherapy.Conclusion:Disease characteristics are similar to international reports,while differences of diagnosis and treatment exist.This study can provide evidences for revisions of the guideline on bladder cancer in China.Kaiwen Li Tianxin Lin Wei Xue Xin Mu Enci Xu Xu Yang Fubao Chen Guangyong Li Lulin Ma Guoliang Wang Chaozhao Liang Haoqiang Shi Ming Li Mao Tang Xueyi Xue Yisong Lv Yaoliang Deng Chengyang Li Zhiwen Chen Xiaozhou Zhou Fengshuo Jin Xudong Liu Jinxin Wei Lei Shi Xin Gou Weiyang He Liqun Zhou Lin Cai Baiye Jin Guanghou Fu Xiangbo Kong Hongyan Sun Ye Tian Lang Feng Tiejun Pan Yiyi Wu Dongwen Wang Hailong Hao Benkang Shi Yaofeng Zhu Qiang Wei Ping Han Changli Wu Dawei Tian Zhangqun Ye Zheng Liu Zhiping Wang Junqiang Tian Lin Qi Minfeng Chen Wei Li Jinchun Qi Gongxian Wang Longlong Fu Zhaolin Sun Guangheng Luo Zhoujun Shen Zhaowei Zhu Jinchun Xing Zhun Wu Dong Wei Xin Chen Yanqun Na Hongfeng Guo Chunxi Wang Zhihua Lu Chuize Kong Yang Liu Jin Yang Jianyun Hu Xin Gao Jielin Li Changjun Yin Pu Li Shan Chen Zhen Du Jiongming Li Yongji Yan Xu Zhang Shuang Huang Fangjian Zhou Zhiling Zhang Yinghao Sun Shuxiong Zeng Song Cen Jiaquan Zhou Hanzhong Li Jin Wen Jian Huang 2015Asian Journal of Urology2015,2,2:21
13A step metallogenetic model for gold deposits in the northwestern Shandong Peninsula, China显示文摘Based on our study of the nature and variation of mineralization-controlling faults in their deep extension and the spatial distribution of gold orebodies in the northwestern Shandong Peninsula (NSP), here we propose that the gold deposits in the Jiaojia gold belt are controlled by listric faults and the gold deposits in the NSP are controlled by extensional fault system. We also suggest that there is a multiple mineralization space in the deep part of the NSP gold belt. As steps or benches occur along the deep extention of the listric fault where its dipping angle changes from steep to gentle, a number of gold deposits are correspondingly distributed as a steplike pattern, which is named as a step metallogenetic model for gold deposits in the NSP. The gold deposits in Shandong Peninsula were formed in the Cretaceous when the crust in the region experienced extention and thinning following the strong collision between North China Plate and Yangtze Plate during the Triassic. Crust anataxis, fluid remobilization, and extention-detachement of the crust are the leading factors for the gold mineralization.SONG MingChun YI PiHou XU JunXiang CUI ShuXue SHEN Kun JIANG HongLi YUAN WenHua WANG HuaJiang 2012Science China Earth Sciences2012,55,6:21
14Dendritic Cells Transduced with SOCS1 Gene Exhibit Regulatory DC Properties and Prolong Allograft Survival显示文摘SOCS1 is a key regulator of cytokine signaling and is important for maintaining balance in the immune system. It is thought to participate in negative feedback loops in cytokine signaling and may be an important signal for the regulation of dendritic cell (DC) maturation. However, it remains unclear whether DCs transduced with SOCS1 exhibit characteristics of regulatory DCs and induce allogeneic T-cell hyporesponsiveness. In this study, we constructed adenoviral vector coding SOCS1 (Ad-SOCS1) that can efficiently increase SOCS1 gene expression in bone marrow-derived dendritic cells. DCs transduced with Ad-SOCS1 (DC-SOCS1) expressed low levels of costimulatory and MHC molecules, were resistant to maturation and activation stimulation, induced allogeneic T-cell hyporesponsiveness, and promoted the generation of regulatory-like T cells in vitro. DC-SOCS1 pretreatment significantly prolonged the survival of allografts and led to a substantial increase in the generation of regulatory T cells. Our data suggest that SOCS1 inhibits DC maturation and induces regulatory DC generation, therefore possessing therapeutic potential to prevent rejection in organ transplantation.Hong Fu Shaohua Song Fang Liu Zhijia Ni Xiaoyun Shen Liang Xiao Guoshan Ding Quanxing Wang 2009Cellular & Molecular Immunology2009,6,2:20

16Growth inhibition induced by short hairpin RNA to silence survivin gene in human pancreatic cancer cells显示文摘BACKGROUND:Survivin is known to be overexpressed in various human malignancies,including pancreatic cancer,and mediates cancer cell proliferation and tumor growth,so the regulation of this molecule could be a new strategy for treating pancreatic cancer.In this study,short hairpin RNAs (shRNAs) specific to survivin were introduced into human pancreatic cancer Patu8988 cells to investigate the inhibitory effects on survivin expression and cell proliferation in vitro and in vivo.METHODS:Three kinds of shRNA specific to the survivin gene were designed and cloned into eukaryotic expression plasmid pGenesil-1 vector.Subsequently the recombinant plasmids were transfected into human pancreatic cancer Patu8988 cells with lipfectamine TM 2000 reagent.The mRNA and protein expressions of survivin in the transiently transfected Patu8988 cells were determined by RT-PCR,flow cytometry,and Western blotting analysis.The proliferation inhibition rates of stably transfected Patu8988 cells were determined by MTT assay.The antitumor activities of the three kinds of survivin-shRNA plasmids were evaluated in BALB/c nude mice inoculated with Patu8988 cells and bearing human pancreatic cancer.RESULTS:The three survivin-shRNA plasmids named pGenesil1-survivin-1,pGenesil-1-survivin-2 and pGenesil-1-survivin-1+2 (with double interfering RNA sites) were successfully constructed,and were confirmed by restriction enzyme cutting and sequencing.At 48 hours after transfection,the expression of survivin mRNA and protein was inhibited in Patu8988 cells transfected with pGenesil-1-survivin-1,pGenesil-1-survivin-2,and pGenesil-1-survivin-1+2 when compared with that of either pGenesil-1-NC (with scrambled small interfering RNA) transfected cells or control cells (P<0.05).The MTT results showed that the proliferation rates of Patu8988 cells stably transfected with survivin-shRNA plasmids were reduced when compared with that of either pGenesil-1-NC transfected cells or control cells (P<0.01).Furthermore,when Patu8988 cells stably transfected with survivin-shRNA were injected into BALB/c nude mice,tumor growth was dramatically lower and the tumor was smaller than that of either pGenesil-1-NC transfected cells or control cells (P<0.01).The inhibitory effect of pGenesil1-survivin-1 was the best among the three kinds of survivinshRNA plasmids,but no combination of inhibitory effects was found in pGenesil-1-survivin-1+2.CONCLUSIONS:shRNAs specific to survivin have gene silencing effects and inhibit pancreatic cancer cell proliferation.shRNA activity against survivin could be of potential value in gene therapy for pancreatic cancer.However,shRNAs with double combining sites did not significantly enhance the interference compared with single site shRNAs,therefore further studies on this are needed.Shen, Yong-Mei Yang, Xiao-Chun Song, Miao-Li Qin, Chen-Hao Yang, Chen Sun, Yi-Hui 2010Hepatobiliary & Pancreatic Diseases International2010,9,1:18

18Effects of electroacupuncture at Zusanli(ST36) on inflammatory cytokines in a rat model of smokeinduced chronic obstructive pulmonary disease显示文摘OBJECTIVE:Improvement in lung function was reported after acupuncture treatment of chronic obstructive pulmonary disease(COPD),but little is known about the underlying mechanisms. Because an immune response imbalance could be seen in COPD,we hypothesize that electroacupuncture(EA) may play a role in regulating inflammatory cytokines and contribute to lung protection in a rat model of smoke-induced COPD. METHODS:A COPD model using male Sprague-Dawley rats exposed to cigarette smoke was established.The rats were randomly divided into four groups(control,sham,COPD,and COPD plus EA),and COPD model was evaluated by measuring pulmonary pathological changes and lung function.EA was applied to the acupuncture point Zusanli(ST36) for 30 min/d for 14 d in sham and COPD rats.Bronchoalveolar lavage fluid(BALF) was used to measure levels of tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),and malonaldehyde(MDA). RESULTS:Compared with the control rats,COPD rats had significant changes in lung resistance(R_L) and lung compliance(C_L)(both P<0.01),bronchi and bronchiole airway obstruction(P<0.01),and levels of MDA,TNF-α,and IL-1β(P<0.01).There were no significant differences between the control and the sham groups.Compared with the COPD rats,the COPD plus EA rats had decreased R_L and increased C_L(both P<0.05),and reduced bronchi and bronchiole airway obstruction(P<0.05,P<0.01,respectively),while levels of TNF-α,IL-1β, and MDA in BALF were lowered(P<0.05 and P<0.01,respectively).However,TNF-αand IL-1βlevels of the EA group rats remained higher than those of the control group(P<0.05). CONCLUSION:EA at ST36 can reduce lung injury in a COPD rat model,and beneficial effects may be related to down-regulation of inflammatory cytokines.The anti-inflammatory and antioxidant effects mav prolong the clinical benefit of EA.Wen-ye Geng Zi-bing Liu Na-na Song Gui-hong Zhang Wei-zhong Jin Wang Zhou Li Li Yin-xiang Cao Da-nian Zhu Lin-lin Shen 2013Journal of Integrative Medicine2013,11,3:18
19A comparative study between Embosphere~ and conventional transcatheter arterial chemoembolization for treatment of unresectable liver metastasis from GIST显示文摘Objective:Transcatheter arterial chemoembolization(TACE) is a standard treatment for hepatocellular carcinoma(HCC) and/or some unresectable liver metastasis tumors.Hypervascular liver metastatic lesions such as metastasis from gastrointestinal stromal tumor(GIST) are an indication for transcatheter arterial embolization(TAE).The purpose of this study was to evaluate the efficacy and safety of Embosphere~-TAE(Embo-TAE) in comparison with conventional TACE(cTACE) for the treatment of liver metastasis from GIST.Methods:A total of 45 patients who underwent TACE between Aug 2008 and Feb 2013 were enrolled.Patients with GIST who underwent TAE with Embosphere~(n=19) were compared with controls who received cTACE(n=26).The primary end points were treatment response and treatment-related adverse events.The secondary end points were progression-free survival(PFS) and overall survival(OS).Results:The treatment response of Embo-TAE group was significantly higher than that of the cTACE group(P<0.001).The PFS was significantly better in the Embosphere~-group than in the cTACE group(56.6 and 42.1 weeks,respectively;P=0.003).However,there was no statistically significant difference in liver toxicity between the two groups(P>0.05).The median OS in the Embo-TAE group was longer than that in the cTACE group(74.0 weeks,95% CI:68.2-79.8 vs.61.7 weeks,95% CI:56.2-67.2 weeks)(unadjusted P=0.045).The use of Embo-TAE significantly reduced the risk of death in patients with GIST with liver metastases according to the Cox proportional hazards regression model [hazard ratio(HR):0.149;95% CI:0.064-0.475].Conclusions:TAE with Embosphere~ showed better treatment response and delayed tumor progression compared with cTACE.There was no significant difference in treatment-related hepatic toxicities.EmboTAE thus appears to be a feasible and promising approach in the treatment of liver metastasis from GIST.Guang Cao Xu Zhu Jian Li Lin Shen Renjie Yang Hui Chen Xiaodong Wang Song Gao Haifeng Xu Linzhong Zhu Peng Liu Jianhai Guo 2014Chinese Journal of Cancer Research2014,26,1:18
