1Notch signaling mediated by TGF-β/Smad pathway in concanavalin A-induced liver fibrosis in rats显示文摘AIM To explore the exact interaction between Notch and transforming growth factor(TGF)-β signaling in liver fibrosis. METHODS We established a rat model of liver fibrosis induced by concanavalin A. Peripheral blood mononuclear cells(PBMCs) were isolated from the modeled rats, and cultured with γ-secretase inhibitor DAPT and TGF-β inhibitor for 24 h. The m RNA levels of Notch and TGF-β signaling were detected by quantitative real-time polymerase chain reaction. Expression of Notch and TGF-β proteins was analyzed by western blotting.RESULTS Compared to control rats, Notch and TGF-β signaling was activated in PBMCs of model rats. Administration of DAPT and TGF-β inhibitor suppressed Notch and TGF-β signal transducer in PBMCs of model rats. DAPT reduced m RNA and protein expression of TGF-β signaling, such as TGF-β1 and Smad3. TGF-β inhibitor also downregulated Notch1, Hes1 and Hes5, and m RNA and protein expression of the Notch signaling pathway.CONCLUSION Notch and TGF-β signaling play a role in liver fibrosis. TGF-β signaling upregulates Notch signaling, which promotes TGF-β signaling.Yi Wang Ruo-Wu Shen Bing Han Zhen Li Le Xiong Feng-Yu Zhang Bei-Bei Cong Bei Zhang 2017World Journal of Gastroenterology2017,23,13:25
2Detection of hepatitis C virus NS5 protein and genome in Chinese carcinoma of the extrahepatic bile duct and its significance显示文摘AIM To investigate the hepatitis C virus(HCV)infection in the tissues of carcinoma ofextrahepatic bile duct and study theircorrelation.METHODS HCV NS5 protein and HCV RNA weredetected by labeled streptavidin biotin(LSAB)method and in situ reverse transcriptionpolymerase chain reaction(IS-RT-PCR)insections of 51 cases of carcinoma ofextrahepatic bile duct and 34 cases of controlgroup(without malignant biliary disease).RESULTS In 51 cases of carcinoma ofextrahepatic bile duct,HCV NS5 protein wasdetected in 14(27.5%),which was clearlystained in the cytoplasm of cancer cell but not inthe nucleus or cell membrane.HCV RNA wasdetected in 18(35.4%),which was located inthe nucleus of cancer cell in 12 cases and in thecytoplasm in 6 cases.HCV NS5 protein and RNAcoexistence was found in 2 cases.In 34 cases ofcontrol group,HCV RNA was detected in 2(5.9%).HCV NS5 protein and RNA positive cellswere found either scattered or in clusters.CONCLUSION The prevalence of hepatitis C viral infection in the tissues of carcinoma ofextrahepatic bile duct was significantly higherthan in control group(X^2=9.808,P=0.002).The findings suggest a correlation between HCVinfection and carcinoma of extrahepatic bileduct,which is different from the traditionalviewpoint.HCV infection might be involved inthe development of carcinoma of extrahepaticbile duct.Ming Yi Chen Zhi Qiang Huang Le Zhen Chen Ya Bing Gao Rui Yun Peng De Wen Wang 2000World Journal of Gastroenterology2000,6,6:19
3Validation of the chinese version of the EORTC QLQ-CR29 in patients with colorectal cancer显示文摘AIM To assess the validity and reliability of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Colorectal Cancer 29(EORTC QLQ-CR29) in Chinese patients with colorectal cancer(CRC). METHODS From March 2014 to January 2015, 356 patients with CRC from four different hospitals in China were enrolled in the study, and all patients self-administered the EORTC QLQ-CR29 and the quality of life core questionnaire(EORTC QLQ-C30). Evaluation of the scores was based on the Karnofsky Performance Scale(KPS). The reliability and validity of the questionnaires were assessed by Cronbach's α coefficient, the Spearman correlation test and Wilcoxon rank sum test.RESULTS The EORTC QLQ-CR29 showed satisfactory reliability(α > 0.7), although the urinary frequency and blood and mucus in stool dimensions had only moderate reliability(α = 0.608). The multitrait scaling analyses showed good convergent(r > 0.4) and discriminant validity. Significant differences were obtained for each item in the different KPS subgroups(KPS ≤ 80; KPS > 80). body image and most single-item dimensions showed statistically significant differences in patients with a stoma compared with the rest of the patients. CONCLUSION The EORTC QLQ-CR29 exhibits high validity and reliability in Chinese patients with CRC, and can therefore be recommended as a valuable tool for the assessment of quality of life in these patients.Jin-bo Lin Lei Zhang Dong-Wen Wu Zhou-Huan xi xue-Jun Wang Yun-Shou Lin Wakana Fujiwara Jing-Ru Tian Min Wang Peng Peng Ai Guo Zhen Yang Le Luo Ling-Ya Jiang Qia-Qia Li xue-Ying Zhang Yun-Feng Zhang Hou-Wei xu bing Yang xun-Lin Li Yi-xiong Lei 2017World Journal of Gastroenterology2017,23,10:12

6An individualized immune signature of pretreatment biopsies predicts pathological complete response to neoadjuvant chemoradiotherapy and outcomes in patients with esophageal squamous cell carcinoma显示文摘No clinically available biomarkers can predict pathological complete response(pCR)for esophageal squamous cell carcinomas(ESCCs)with neoadjuvant chemoradiotherapy(nCRT).Considering that antitumor immunity status is an important determinant for nCRT,we performed an integrative analysis of immune-related gene profiles from pretreatment biopsies and constructed the first individualized immune signature for pCR and outcome prediction of ESCCs through a multicenter analysis.During the discovery phase,14 differentially expressed immune-related genes(DEIGs)with greater than a twofold change between pCRs and less than pCRs(Chaoqi Zhang Guochao Zhang Nan Sun Zhen Zhang Liyan Xue Zhihui Zhang Haijun Yang Yuejun Luo Xiaoli Zheng Yonglei Zhang Yufen Yuan Ruixue Lei Zhaoyang Yang Bo Zheng Le Wang Yun Che Feng Wang Sihui Wang Shugeng Gao Qi Xue Yi Zhang Jie He 2020Signal Transduction and Targeted Therapy2020,5,1:7
7Surface acoustic wave humidity sensors based on uniform and thickness controllable graphene oxide thin films formed by surface tension显示文摘Graphene oxide(GO)is a promising candidate for humidity sensing,and the uniformity and thickness of GO films are important for the reproducibility and test signal strength of humidity sensors.In this paper,uniform and thicknesscontrollable GO films are first formed by the surface tension of different concentrations of GO solution and then transferred to surface acoustic wave(SAW)humidity sensors.This GO film formation and transfer process has very good repeatability and stability,as evidenced by the humidity response of the sensors.With the help of the uniform and highly oxidized GO film,the humidity sensors show a significantly high sensitivity(absolute sensitivity of 25.3 kHz/%RH and relative sensitivity of 111.7 p.p.m./%RH)in a wide test range from 10%RH to 90%RH with very little hysteresis(<1%RH).The sensors achieve good reversibility,excellent short-term repeatability and stability.Moreover,the humidity sensors also show a fast response and recovery time of<10 s.Xianhao Le Yihan Liu Li Peng Jintao Pang Zhen Xu Chao Gao Jin Xie 2019Microsystems & Nanoengineering2019,5,1:4
8Neuroprotective effects of Asiaticoside显示文摘In the central nervous system, Asiaticoside has been shown to attenuate in vitro neuronal damage caused by exposure to β-amyloid. In vivo studies demonstrated that Asiaticoside could attenuate neurobehavioral, neurochemical and histological changes in transient focal middle cerebral artery occlusion animals. In addition, Asiaticoside showed anxiolytic effects in acute and chronic stress animals. However, its potential neuroprotective properties in glutamate-induced excitotoxicity have not been fully studied. We investigated the neuroprotective effects of Asiaticoside in primary cultured mouse cortical neurons exposed to glutamate-induced excitotoxicity invoked by N-methyl-D-aspartate. Pretreatment with Asiaticoside decreased neuronal cell loss in a concentration-dependent manner and restored changes in expression of apoptotic-related proteins Bcl-2 and Bax. Asiaticoside pretreatment also attenuated the upregulation of NR2 B expression, a subunit of N-methyl-D-aspartate receptors, but did not affect expression of NR2 A subunits. Additionally, in cultured neurons, Asiaticoside significantly inhibited Ca2+ influx induced by N-methyl-D-aspartate. These experimental findings provide preliminary evidence that during excitotoxicity induced by N-methyl-D-aspartate exposure in cultured cortical neurons, the neuroprotective effects of Asiaticoside are mediated through inhibition of calcium influx. Aside from its anti-oxidant activity, down-regulation of NR2B-containing N-methyl-D-aspartate receptors may be one of the underlying mechanisms in Asiaticoside neuroprotection.Feng-yan Qi Le Yang Zhen Tian Ming-gao Zhao Shui-bing Liu Jia-ze An 2014Neural Regeneration Research2014,9,13:3

10Cobalt and nitrogen codoped porous carbon as superior bifunctional electrocatalyst for oxygen reduction and hydrogen evolution reaction in alkaline medium显示文摘Cobalt and nitrogen codoped carbon materials(Co-N-C) were fabricated by pyrolysis of the mixture of poly(4-vinylpyridine) and cobalt chloride using SiO_2 nanoparticles as hard template, which were the first transition metal/nitrogen-codoped carbon bifunctional electrocatalyst derived from noncarbonizable polymer for ORR and HER. The as-made Co-N-C possessed hierarchical pore structure and high specific surface area, achieving excellent electrocatalytic performances for ORR and HER. Its ORR catalytic performances were comparable to those of Pt/C catalyst and its HER catalytic performances were superior to those of most doped carbon catalysts in KOH electrolyte. Moreover, its bifunctional electrocatalytic performances for ORR and HER were better than those of most bifunctional doped carbon catalysts in alkaline electrolyte.Xiaoxia Chen Xiangjun Zhen Hongyu Gong Le Li Jianwei Xiao Zhi Xu Deyue Yan Guyu Xiao Ruizhi Yang 2019Chinese Chemical Letters2019,30,3:2
11A fast boundary protection for an AC transmission line connected to an LCCHVDC inverter station显示文摘For AC transmission lines connected to an LCC-HVDC inverter station,commutation failure can lead to the wrong operation of traditional protection.To solve the problem,this paper proposes a fast protection scheme using transient information from one end of the AC line.The boundary frequency characteristics of the AC line connected to LCC-HVDC inverter are analyzed first.This reveals the existence of significant attenuation on both high frequency signals and some specific frequency signals.Based on the boundary characteristics,a novel boundary protection principle utilizing a backward traveling wave is then proposed.A PSCAD/EMTDC simulation model of a±800 kV LCC-HVDC and 500 kV AC transmission system is established,and different fault cases are simulated.The simulation results prove that the novel protection principle is immune to commutation failure,fault resistance and fault type.Zhen Liu Houlei Gao Sibei Luo Le Zhao Yuyao Feng 2020Protection and Control of Modern Power Systems2020,5,1:2

14Comparison of the Prevalence and Characteristics Between EWGSOP1-and EWGSOP2-defined Sarcopenia in Patients with Colorectal Cancer显示文摘Background Sarcopenia,as diagnosed by the former EWGSOP1 guidelines,was prevalent in cancer patients.The aim of this study was to examine the diagnostic capabilities of the previous and current guidelines,and to compare the clinicopathological features between patients diagnosed using the algorithms comprising the EWGSOP1 and EWGSOP2 guidelines.Methods We conducted a study including colorectal cancer patients from July 2014 to July 2019.The skeletal muscle mass,muscle attenuation,handgrip strength,and 6-meter usual gait speed were prospectively measured to define sarcopenia once patients were hospitalized.Results Of a total of 840 patients,160(19.0%)patients were diagnosed with sarcopenia based on the EWGSOP1 and 241(28.7%)patients were diagnosed based on the EWGSOP2.The numbers of patients diagnosed with sarcopenia and severe sarcopenia were much higher when the EWGSOP2 guidelines were used(160 vs.241 and 74 vs.140,respectively).The patients with EWGSOP2-defined sarcopenia showed a lower plasma albumin concentration(37.4 vs.36.4,P=0.039)but higher BMI(21.01 vs.22.22,P<0.001)than the patient diagnosed based on the EWGSOP1 guidelines.Conclusion The diagnosis of sarcopenia based on screening using the EWGSOP1 and EWGSOP2 guidelines differs considerably,at least in patients with colorectal cancer.In addition,the patients with EWGSOP2-diagnosed sarcopenia also showed a trend toward a lower plasma albumin level and higher BMI.Feng Min Zhang Zhen Yu Han Ping Shi Cheng Le Zhuang 2020Journal of Nutritional Oncology2020,5,1:2
15Contribution of Temperature Increase to Restrain the Transmission of COVID-19显示文摘The COVID-19 outbreak has already become a global pandemic and containing this rapid worldwide transmission is of great challenge.The impacts of temperature and humidity on the COVID-19 transmission rate are still under discussion.Here,we elucidated these relationships by utilizing two unique scenarios,repeated measurement and natural experiment,using the COVID-19 cases reported from January 23–February 21,2020,in China.The modeling results revealed that higher temperature was most strongly associated with decreased COVID-19 transmission at a lag time of 8 days.Relative humidity(RH)appeared to have only a slight effect.These findings were verified by assessing SARSCoV-2 infectivity under the relevant conditions of temperature(4C–37C)and RH(>40%).We concluded that temperature increase made an important,but not determined,contribution to restrain the COVID19 outbreak in China.It suggests that the emphasis of other effective controlling polices should be strictly implemented to restrain COVID19 transmission in cold seasons.Mengyuan Ren Rongjuan Pei Bahabaike Jiangtulu Junxi Chen Tao Xue Guofeng Shen Xiaoru Yuan Kexin Li Changxin Lan Zhen Chen Xinwen Chen Yun Wang Xiaoqian Jia Zewu Li Audil Rashid Tippawan Prapamontol Xiuge Zhao Zhaomin Dong Yali Zhang Le Zhang Rongwei Ye Zhiwen Li Wuxiang Guan Bin Wang 2021The Innovation2021,2,1:2
16Blue AIEgens bearing triphenylethylene peripheral:adjustable intramolecular conjugation and good device performance显示文摘The new approaches to construct deep blue aggregation-induced emission(AIE) materials have been explored, which control the conjugation by two different strategies, to make a great step for the commercialization of organic light-emitting diodes. In order to shorten the intramolecular conjugation length, triphenylethylene(t PE)was utilized to construct blue AIEgens as peripheral groups,instead of tetraphenylethylene(TPE), the famous AIE star molecule, to yield three blue AIEgens of 3,4-Bt PE-PI, 4,4-Bt PE-PI and 4,4-Bt PE-PPI. Nondoped electroluminescence devices are fabricated by using these three AIEgens as the emitting material layer, the best performance of 3.8 cd/A as the maximum current efficiency achieved at the commission internationale de l'Eclairage coordinates of(0.17, 0.18).Can Wang Le Li Xuejun Zhan Zhijun Ruan Yujun Xie Quanyuan Hu Shanghui Ye Qianqian Li Zhen Li 2016Science Bulletin2016,61,22:2
