2Survival of transplanted neurotrophin-3 expressing human neural stem cells and motor function in a rat model of spinal cord injury显示文摘<正>BACKGROUND:Many methods have been attempted to repair nerves following spinal cord injury, including peripheral nerve transplantation,Schwann cell transplantation,olfactory ensheathing cell transplantation,and embryonic neural tissue transplantation.However,there is a need for improved outcomes. OBJECTIVE:To investigate the repair feasibility for rat spinal cord injury using human neural stem cells(hNSCs) genetically modified by lentivirus to express neurotrophin-3. DESIGN,TIME AND SETTING:In vitro cell biological experiment and in vivo randomized,controlled, genetic engineering experiment were performed at the Third Military Medical University of Chinese PLA and First People's Hospital of Yibin,China from March 2006 to December 2007. MATERIALS:A total of 64 adult,female,Wistar rats were used for the in vivo study.Of them,48 rats were used to establish models of spinal cord hemisection,and were subsequently equally and randomly assigned to model,genetically modified hNSC,and normal hNSC groups.The remaining 16 rats served as normal controls. METHODS:hNSCs were in vitro genetically modified by lentivirus to secrete both green fluorescence protein and neurotrophin-3.Neurotrophin-3 expression was measured by Western blot. Genetically modified hNSC or normal hNSC suspension(5×10~5) was injected into the rat spinal cord following T_(10) spinal cord hemisection.A total of 5μL Dulbecco's-modified Eagle's medium was infused into the rat spinal cord in the model group.Transgene expression and survival of transplanted hNSCs were determined by immunohistochemistry.Motor function was evaluated using the Basso,Beattie,and Bresnahan(BBB) scale. MAIN OUTCOME MEASURES:The following parameters were measured:expression of neurotrophin-3 produced by genetically modified hNSCs,transgene expression and survival of hNSCs in rats,motor function in rats. RESULTS:hNSCs were successfully genetically modified by lentivirus to stably express neurotrophin-3.The transplanted hNSCs primarily gathered at,or around,the injection site two weeks following transplantation,and gradually migrated towards the surrounding tissue. Transplanted hNSCs were observed 7.0-8.0 mm away from the injection site.In addition,hNSCs were observed 10 weeks after transplantation.At week 4,BBB locomotor scores were significantly greater in the genetically modified hNSC and normal hNSC groups,compared with the model group (P<0.05),and scores were significantly greater in the genetically modified hNSC group compared with the normal hNSC group(P<0.05). CONCLUSION:hNSCs were genetically modified with lentivirus to stably secrete neurotrophin-3. hNSCs improved motor function recovery in rats following spinal cord injury.Peiqiang Cai Guangyun Sun Peishu Cai Martin Oudega Rui Xiao Xuewen Wang Wei Li Yunbing Shu Cheng Cai Haihao Yang Xuebing Shan Wuhua Luo 2009Neural Regeneration Research2009,4,7:18

7MiR-146a-5p targeting SMAD4 and TRAF6 inhibits adipogenensis through TGF-β and AKT/mTORC1 signal pathways in porcine intramuscular preadipocytes显示文摘Background: Intramuscular fat(IMF) content is a vital parameter for assessing pork quality. Increasing evidence has shown that microRNAs(miRNAs) play an important role in regulating porcine IMF deposition. Here, a novel miRNA implicated in porcine IMF adipogenesis was found, and its effect and regulatory mechanism were further explored with respect to intramuscular preadipocyte proliferation and differentiation.Results: By porcine adipose tissue miRNA sequencing analysis, we found that miR-146a-5p is a potential regulator of porcine IMF adipogenesis. Further studies showed that miR-146a-5p mimics inhibited porcine intramuscular preadipocyte proliferation and differentiation, while the miR-146a-5p inhibitor promoted cell proliferation and adipogenic differentiation. Mechanistically, miR-146a-5p suppressed cell proliferation by directly targeting SMAD family member 4(SMAD4) to attenuate TGF-β signaling. Moreover, miR-146a-5p inhibited the differentiation of intramuscular preadipocytes by targeting TNF receptor-associated factor 6(TRAF6) to weaken the AKT/mTORC1 signaling downstream of the TRAF6 pathway.Conclusions: MiR-146a-5p targets SMAD4 and TRAF6 to inhibit porcine intramuscular adipogenesis by attenuating TGF-β and AKT/mTORC1 signaling, respectively. These findings provide a novel miRNA biomarker for regulating intramuscular adipogenesis to promote pork quality.Que Zhang Rui Cai Guorong Tang Wanrong Zhang Weijun Pang 2021Journal of Animal Science and Biotechnology2021,12,1:10

9Analysis of inpatient payments of breast cancer patients with different medical insurance coverages in China(mainland) in 2011–2015显示文摘Objective: An understanding of the levels and trends of medical cost is made for breast cancer patients with different medical insurance coverages in China(mainland), in an attempt to offer a clue to further control the costs.Methods: The inpatient payments of 9,716,180 breast cancer patients spent in medical institutions of different types and grades during 2011–2015 were collected from the inpatient medical record home page(IMRHP) dataset.The data were then processed with SAS(Version 9.3; SAS Institute, Cary, NC, USA). Indicators like means,increase(decrease) percentages were used to descriptively analyze the average hospitalization expense of each time(AHEET) and its trends of breast cancer patients with different medical insurance coverages treated in medical institutions of different types and grades.Results:In 2011–2015,the AHEET borne by breast cancer patients in China had been constantly increasing.Specifically,the self-pay inpatients had the largest increase,inpatients covered by Urban Employee Basic Medical Insurance(UEBMI)and Urban Resident Basic Medical Insurance(URBMI)were the next,and those covered by New Rural Cooperative Medical System(NRCMS)had the least increase.Breast cancer inpatient treated in public hospitals had quite greater increase and higher expenditure level than those in private hospitals.The AHEET borne by the inpatients in Grade 3 hospitals had greater increase and higher cost than those in Grade 2 hospitals.Conclusions:The inpatient payments of breast cancer patients will be wisely controlled by reducing the number of self-pay inpatients,taking advantage of restriction mechanism of the medical insurances,and promoting healthy competition between private hospitals and public hospitals.The economic burden imposed on the society by breast cancer can be relieved through further control of inpatient payments of UEBMI-and URBMI-covered breast cancer patients and of Grade 3 hospitals.Rui Li Liang Zhang Jinxia Yang Yue Cai Wanqing Chen Lan Lan Ming Xue Qun Meng 2017Chinese Journal of Cancer Research2017,29,5:9
10Estimating survival benefit of adjuvant therapy based on a Bayesian network prediction model in curatively resected advanced gallbladder adenocarcinoma显示文摘BACKGROUND The factors affecting the prognosis and role of adjuvant therapy in advanced gallbladder carcinoma(GBC)after curative resection remain unclear.AIM To provide a survival prediction model to patients with GBC as well as to identify the role of adjuvant therapy.METHODS Patients with curatively resected advanced gallbladder adenocarcinoma(T3 and T4)were selected from the Surveillance,Epidemiology,and End Results database between 2004 and 2015.A survival prediction model based on Bayesian network(BN)was constructed using the tree-augmented na?ve Bayes algorithm,and composite importance measures were applied to rank the influence of factors on survival.The dataset was divided into a training dataset to establish the BN model and a testing dataset to test the model randomly at a ratio of 7:3.The confusion matrix and receiver operating characteristic curve were used to evaluate the model accuracy.RESULTS A total of 818 patients met the inclusion criteria.The median survival time was 9.0 mo.The accuracy of BN model was 69.67%,and the area under the curve value for the testing dataset was 77.72%.Adjuvant radiation,adjuvant chemotherapy(CTx),T stage,scope of regional lymph node surgery,and radiation sequence were ranked as the top five prognostic factors.A survival prediction table was established based on T stage,N stage,adjuvant radiotherapy(XRT),and CTx.The distribution of the survival time(>9.0 mo)was affected by different treatments with the order of adjuvant chemoradiotherapy(cXRT)>adjuvant radiation>adjuvant chemotherapy>surgery alone.For patients with node-positive disease,the larger benefit predicted by the model is adjuvant chemoradiotherapy.The survival analysis showed that there was a significant difference among the different adjuvant therapy groups(log rank,surgery alone vs CTx,P<0.001;surgery alone vs XRT,P=0.014;surgery alone vs cXRT,P<0.001).CONCLUSION The BN-based survival prediction model can be used as a decision-making support tool for advanced GBC patients.Adjuvant chemoradiotherapy is expected to improve the survival significantly for patients with node-positive disease.Zhi-Min Geng Zhi-Qiang Cai Zhen Zhang Zhao-Hui Tang Feng Xue Chen Chen Dong Zhang Qi Li Rui Zhang Wen-Zhi Li Lin Wang Shu-Bin Si 2019World Journal of Gastroenterology2019,25,37:9

15Advances in research of the mid-deep South China Sea circulation显示文摘The South China Sea(SCS)is a large marginal sea connecting the Indian and Pacific oceans.Under the factors of monsoons,strait transport,and varied bathymetry,the SCS presents a three-layer structure and strong diapycnal mixing which is far greater than that in the open ocean.Theoretical analysis and observations reveal that internal tides,internal solitary waves,and strong winds are the sources of the strong mixing in the northern SCS.A major consequence of the strong mixing is an active mid-deep circulation system.This system promotes exchange of water between the SCS and adjacent oceans,and also regulates the upper layer of wind-driven circulation,making the 3 dimensional SCS circulation clearly different from that in other tropical and subtropical marginal seas.The mass transport capacity of the mid-deep circulation has a substantial impact on marine sedimentation,the biogeochemical cycle,and other processes in the SCS.This paper summarizes the recent advances in middeep sea circulation dynamics of the SCS,and discusses the opportunities and challenges in this area.Dongxiao WANG Qiang WANG Shuqun CAI Xiaodong SHANG Shiqiu PENG Yeqiang SHU Jingen XIAO Xiaohui XIE Zhiwei ZHANG Zhiqiang LIU Jian LAN Dake CHEN Huijie XUE Guihua WANG Jianping GAN Xinong XIE Rui ZHANG Hui CHEN Qingxuan YANG 2019Science China Earth Sciences2019,62,12:8
16The U-Pb chronologic evidence and sedimentary responses of Silurian tectonic activities at northeastern margin of Tarim Basin显示文摘U-Pb ages of Devonian detrital zircons from Tabei Uplift have been determined through LA-ICP-MS test technology.The results revealed that most zircon ages concentrate on 460-414 Ma,especially around 436-423 Ma,indicating possible occurrences of strong tectonic events at the northern margin of Tarim Basin during that period.Combined with previous researches on the basin marginal orogenic belts,intense tectonic activities developed at the northeast margin of Tarim Basin and its obvious sedimentary responses in basin during the end of Ordovician to Early-Middle Silurian are discussed.These include(1) several unconformities within the Late Ordovician-Silurian,showing truncation,erosion,and onlap characteristics,which reflected the local uplift formed during the surrounding extrusion process;(2) the Silurian fluvial delta system from northeast to southwest in Keping,Yingmaili,Hade,and Caohu areas,which reflected the partial uplift at the northeast margin and provided clastic supply to basin;and(3) as indicated by heavy mineral analysis,the Silurian sediments came mainly from the recycles of orogenic belts provenance,which indicated the compress tectonic setting.In addition,a wide range of red mudstone layer distribution in the upper part of the Silurian may be closely related to the surrounding tectonic uplift and the rapid decline of sea levels.LIU JingYan YANG HaiJun YANG YongHeng CAI ZhenZhong LIU YongQuan RUI ZhiFeng SU ZhenZhen 2012Science China Earth Sciences2012,55,9:7
17A cohort autopsy study defines COVID-19 systemic pathogenesis显示文摘Severe COVID-19 disease caused by SARS-CoV-2 is frequently accompanied by dysfunction of the lungs and extrapulmonary organs.However,the organotropism of SARS-CoV-2 and the port of virus entry for systemic dissemination remain largely unknown.We profiled 26 COVID-19 autopsy cases from four cohorts in Wuhan,China,and determined the systemic distribution of SARS-CoV-2.Xiao-Hong Yao Tao Luo Yu Shi Zhi-Cheng He Rui Tang Pei-Pei Zhang Jun Cai Xiang-Dong Zhou Dong-Po Jiang Xiao-Chun Fei Xue-Quan Huang Lei Zhao Heng Zhang Hai-Bo Wu Yong Ren Zhen-Hua Liu Hua-Rong Zhang Cong Chen Wen-Juan Fu Heng Li Xin-Yi Xia Rong Chen Yan Wang Xin-Dong Liu Chang-Lin Yin Ze-Xuan Yan Juan Wang Rui Jing Tai-Sheng Li Wei-Qin Li Chao-Fu Wang Yan-Qing Ding Qing Mao Ding-Yu Zhang Shu-Yang Zhang Yi-Fang Ping Xiu-Wu Bian 2021Cell Research2021,31,8:7
18An efficient bifunctional electrocatalyst derived from layer-by-layer self-assembly of a three-dimensional porous Co-N-C@graphene显示文摘Three-dimensional (3D) porous carbon-based materials with tunable composition and microstructure are of great interest for the development of oxygen involved electrocatalytic reactions. Here, we report the synthesis of 3D porous carbon-based electrocatalyst by self-assembling Co-metal organic frameworks (MOF) building blocks on graphene via a layer-by-layer technique. Precise control of the structure and morphology is achieved by varying the MOF layer to tune the electrocatalytic properties. The as-produced electrocatalyst exhibits an excellent catalytic activity for the oxygen reduction reaction in 0.1molL^-1 KOH, showing a high onset potential of 0.963V vs. reversible hydrogen electrode (RHE) and a low tafel slope of 54mVdec^-1, compared to Pt/C (0.934V and 52mVdec^-1, respectively). Additionally, it shows a slightly lower potential vs. RHE (1.72V) than RuO2 (1.75V) at 10mAcm^-2 in an alkaline electrolyte. A rechargeable Zn-air battery based on the as-produced 3D porous catalyst demonstrates a high peak power density of 119mWcm^-2 at a cell voltage of 0.578V while retaining an excellent stability over 250 charge-discharge cycles.Shichang Cai Rui Wang William M.

19Meta-analysis of immunohistochemical expression of hypoxia inducible factor-1α as a prognostic role in gastric cancer显示文摘AIM:To conduct a meta-analysis to evaluate the prognostic role of hypoxia inducible factor-1α(HIF-1α)expression in gastric cancer.METHODS:The PubMed,EMBASE,and Web of Science databases were searched systematically for all articles published in English before August,2013.Pooled effect was calculated from the available data to evaluate the association between HIF-1αexpression and 5-year overall survival and tumor clinicopathological features in gastric cancer patients.Pooled odds ratios(ORs)with95%CIs were calculated using either a fixed-effects or a random-effects model.RESULTS:Nine studies matched the selection criteria,which reported on 1103 subjects,548 of whom had HIF-1αpositive expression(50%).This meta-analysis indicated that HIF-1αpositive expression in gastric cancer correlated with lower 5-year overall survival(OR=0.36;95%CI:0.21-0.64),worse tumor differentiation(OR=0.38;95%CI:0.23-0.64),deeper invasion(OR=0.42;95%CI:0.32-0.57),higher rates of lymph node metastasis(OR=2.23;95%CI:1.46-3.40),lymphatic invasion(OR=2.50;95%CI:1.46-4.28),and vascular invasion(OR=1.80;95%CI:1.29-2.51),and higher TNM stage(Ⅲ+Ⅳ)(OR=0.31;95%CI:0.15-0.60).CONCLUSION:HIF-1αpositive expression indicates a poor prognosis for patients with gastric cancer.Further studies are required to confirm these results.Shuang Lin Rui Ma Xue-Yong Zheng Hong Yu Xiao Liang Hui Lin Xiu-Jun Cai 2014World Journal of Gastroenterology2014,20,4:6
20Low complexity construction for quasi-cyclic low-density parity-check codes by Progressive-Block Growth显示文摘In this paper, a novel method for constructing quasi-cyclic LDPC codes with low complexity is proposed. By choosing each circulant permutation matrix sequentially, the proposed method ensures that the current circulant permutation matrix forms no cycles of length smaller than g with the existent circulant permutation matrices. The construction complexity of the proposed algorithm is much lower than that of the random construction. Simulation results show that the proposed QC-LDPC codes can outperform both the random regular LDPC codes with short to moderate block lengths, and the proposed construction method LDPC codes based on the finite geometries in terms of bit-error-rate (BER).REN PinYi YUAN Qiang WANG Rui CAI Jun 2011Science China(Information Sciences)2011,54,2:6
