1Inhibiting effect of antisense oligonucleotides phosphorthioate on gene expression of TIMP-1 in rat liver fibrosis显示文摘AIM To observe the inhibition of antisenseoligonucleotides (asON) phosphorthioate to thetissue inhibitors metalloproteinase-1 (TIMP-1)gene and protein expression in the liver tissue ofimmunologically induced hepatic fibrosis rats.The possibility of reversing hepatic fibrosisthrough gene therapy was observed.METHODS Human serum albumin (HSA) wasused to attack rats, as hepatic fibrosis model, inwhich asONs were used to block the gene andprotein expressing TIMP-1. According to theanalysis of modulator, structure protein, codingseries of TIMP-1 genome, we designed fourdifferent asONs. These asONs were injected intothe hepatic fibrosis models through coccygealvein. The results was observed by RT-PCR formeasuring TIMP-1 mRNA expression,immunohistochemistry and in situ hybridizationfor collagen Ⅰ, Ⅲ, special staining of collagenfiber, and electron microscopic examination.RESULTS Hepatic fibrosis could last within 363days in our modified model. The expressinglevel of TIMP-1 was high during hepatic fibrosisprocess. It has been proved by theimmunohistochemical and the electronmicroscopic examination that the asONphosphorthioate of TIMP-1 could exactly expressin vivo. The effect of colchicine wasdemonstrated to inhibit the expressing level ofmRNA and the content of collagen Ⅰ, Ⅲ in theliver of experimental hepatic fibrosis rats.However, the electron microscopy research andthe pathologic grading of hepatic fibrosisshowed that there was no significant differencebetween the treatment group and the modelgroup (P>0.05).CONCLUSION The experimental rat model ofhepatic fibrosis is one of the preferable modelsto estimate the curative effect of anti-hepaticfibrosis drugs. The asON phosphorthioate ofTIMP-1 could block the gene and proteinexpression of TIMP-1 in the liver of experimentalhepatic fibrosis rats at the mRNA level. It ispossible to reverse hepatic fibrosis, and it isexpected to study a new drug of anti-hepaticfibrosis on the genetic level. Colchicine has verylimited therapeutic effect on hepatic fibrosis,furthermore, its toxicity and side effects areobvious.Qing He Nie Yong Qian Cheng Yu Mei Xie Yong Xing Zhou Yi Zhan Cao The Center of Infectious Disease Diagnosis and Treatment of PLA,Tangdu Hospital,Forth Military Medical University,Xi’an 710038,Shaanxi Province,ChinaDr,Qing He Nie graduated from Qinghai Medical College as a doctor in 1983,got master degree at Beijing 302 Army Hospital in 1993,got doctor degree at the Third Military Medical University in 1998,engaged in postdoctoral research at the Fourth Military Medical University from 1998 to 2000,now an associate professor,specialized in clinical and experimental research of infectious diseases,had more than 90 papers published,coauthor of ten books,first author of one book. 2001World Journal of Gastroenterology2001,7,3:73
2Study of BESIII trigger efficiencies with the 2018 J/ψ data显示文摘Using a dedicated data sample taken in 2018 on the J/ψpeak,we perform a detailed study of the trigger efficiencies of the BESIII detector.The efficiencies are determined from three representative physics processes,namely Bhabha scattering,dimuon production and generic hadronic events with charged particles.The combined efficiency of all active triggers approaches 100%in most cases,with uncertainties small enough not to affect most physics analyses.M.Ablikim M.N.Achasov P.Adlarson S.Ahmed M.Albrecht R.Aliberti A.Amoroso M.R.An Q.An X.H.Bai Y.Bai O.Bakina R.Baldini Ferroli I.Balossino Y.Ban K.Begzsuren N.Berger M.Bertani D.Bettoni F.Bianchi J.Bloms A.Bortone I.Boyko R.A.Briere H.Cai X.Cai A.Calcaterra G.F.Cao N.Cao S.A.Cetin J.F.Chang W.L.Chang G.Chelkov D.Y.Chen G.Chen H.S.Chen M.L.Chen S.J.Chen X.R.Chen Y.B.Chen Z.J Chen W.S.Cheng G.Cibinetto F.Cossio X.F.Cui H.L.Dai X.C.Dai A.Dbeyssi R.E.de Boer D.Dedovich Z.Y.Deng A.Denig I.Denysenko M.Destefanis F.De Mori Y.Ding C.Dong J.Dong L.Y.Dong M.Y.Dong X.Dong S.X.Du Y.L.Fan J.Fang S.S.Fang Y.Fang R.Farinelli L.Fava F.Feldbauer G.Felici C.Q.Feng J.H.Feng M.Fritsch C.D.Fu Y.Gao Y.Gao Y.Gao Y.G.Gao I.Garzia P.T.Ge C.Geng E.M.Gersabeck A Gilman K.Goetzen L.Gong W.X.Gong W.Gradl M.Greco L.M.Gu M.H.Gu S.Gu Y.T.Gu C.Y Guan A.Q.Guo L.B.Guo R.P.Guo Y.P.Guo A.Guskov T.T.Han W.Y.Han X.Q.Hao F.A.Harris H Hüsken K.L.He F.H.Heinsius C.H.Heinz T.Held Y.K.Heng C.Herold M.Himmelreich T.Holtmann Y.R.Hou Z.L.Hou H.M.Hu J.F.Hu T.Hu Y.Hu G.S.Huang L.Q.Huang X.T.Huang Y.P.Huang Z.Huang T.Hussain W.Ikegami Andersson W.Imoehl M.Irshad S.Jaeger S.Janchiv Q.Ji Q.P.Ji X.B.Ji X.L.Ji H.B.Jiang X.S.Jiang J.B.Jiao Z.Jiao S.Jin Y.Jin T.Johansson N.Kalantar-Nayestanaki X.S.Kang R.Kappert M.Kavatsyuk B.C.Ke I.K.Keshk A.Khoukaz P.Kiese R.Kiuchi R.Kliemt L.Koch O.B.Kolcu B.Kopf M.Kuemmel M.Kuessner A.Kupsc M.G.Kurth W.Kühn J.J.Lane J.S.Lange P.Larin A.Lavania L.Lavezzi Z.H.Lei H.Leithoff M.Lellmann T.Lenz C.Li C.H.Li Cheng Li D.M.Li F.Li G.Li H.Li H.Li H.B.Li H.J.Li J.L.Li J.Q.Li J.S.Li Ke Li L.K.Li Lei Li P.R.Li S.Y.Li W.D.Li W.G.Li X.H.Li X.L.Li Z.Y.Li H.Liang H.Liang H.Liang Y.F.Liang Y.T.Liang L.Z.Liao J.Libby C.X.Lin B.J.Liu C.X.Liu D.Liu F.H.Liu Fang Liu Feng Liu H.B.Liu H.M.Liu Huanhuan Liu Huihui Liu J.B.Liu J.L.Liu J.Y.Liu K.Liu K.Y.Liu Ke Liu L.Liu M.H.Liu P.L.Liu Q.Liu Q.Liu S.B.Liu Shuai Liu T.Liu W.M.Liu X.Liu Y.Liu Y.B.Liu Z.A.Liu Z.Q.Liu X.C.Lou F.X.Lu H.J.Lu J.D.Lu J.G.Lu X.L.Lu Y.Lu Y.P.Lu C.L.Luo M.X.Luo b P.W.Luo T.Luo X.L.Luo S.Lusso X.R.Lyu F.C.Ma H.L.Ma L.L.Ma M.M.Ma Q.M.Ma R.Q.Ma R.T.Ma X.X.Ma X.Y.Ma F.E.Maas M.Maggiora S.Maldaner S.Malde Q.A.Malik A.Mangoni Y.J.Mao Z.P.Mao S.Marcello Z.X.Meng J.G.Messchendorp G.Mezzadri T.J.Min R.E.Mitchell X.H.Mo Y.J.Mo N.Yu.Muchnoi H.Muramatsu S.Nakhoul Y.Nefedov F.Nerling I.B.Nikolaev Z.Ning S.Nisar S.L.Olsen Q.Ouyang S.Pacetti X.Pan Y.Pan A.Pathak P.Patteri M.Pelizaeus H.P.Peng K.Peters J.Pettersson J.L.Ping R.G.Ping R.Poling V.Prasad H.Qi H.R.Qi K.H.Qi M.Qi T.Y.Qi T.Y.Qi S.Qian W.-B.Qian Z.Qian C.F.Qiao L.Q.Qin X.S.Qin Z.H.Qin J.F.Qiu S.Q.Qu K.H.Rashid K.Ravindran C.F.Redmer A.Rivetti V.Rodin M.Rolo G.Rong Ch.Rosner M.Rump H.S.Sang A.Sarantsev Y.Schelhaas C.Schnier K.Schoenning M.Scodeggio D.C.Shan W.Shan X.Y.Shan J.F.Shangguan M.Shao C.P.Shen P.X.Shen X.Y.Shen H.C.Shi R.S.Shi X.Shi X.D Shi W.M.Song Y.X.Song S.Sosio S.Spataro K.X.Su P.P.Su F.F.Sui G.X.Sun H.K.Sun J.F.Sun L.Sun S.S.Sun T.Sun W.Y.Sun X Sun Y.J.Sun Y.K.Sun Y.Z.Sun Z.T.Sun Y.H.Tan Y.X.Tan C.J.Tang G.Y.Tang J.Tang J.X.Teng V.Thoren I.Uman B.Wang C.W.Wang D.Y.Wang H.J.Wang H.P.Wang K.Wang L.L.Wang M.Wang M.Z.Wang Meng Wang W.Wang W.H.Wang W.P.Wang X.Wang X.F.Wang X.L.Wang Y.Wang Y.D.Wang Y.F.Wang Y.Q.Wang Y.Y.Wang Z.Wang Z.Y.Wang Ziyi Wang Zongyuan Wang D.H.Wei P.Weidenkaff F.Weidner S.P.Wen D.J.White U.Wiedner G.Wilkinson M.Wolke L.Wollenberg J.F.Wu L.H.Wu L.J.Wu X.Wu Z.Wu L.Xia H.Xiao S.Y.Xiao Z.J.Xiao X.H.Xie Y.G.Xie Y.H.Xie T.Y.Xing G.F.Xu Q.J.Xu W.Xu X.P.Xu F.Yan L.Yan W.B.Yan W.C.Yan Xu Yan H.J.Yang H.X.Yang L.Yang S.L.Yang Y.X.Yang Yifan Yang Zhi Yang M.Ye M.H.Ye J.H.Yin Z.Y.You B.X.Yu C.X.Yu G.Yu J.S.Yu T.Yu C.Z.Yuan L.Yuan X.Q.Yuan Y.Yuan Z.Y.Yuan C.X.Yue A.Yuncu A.A.Zafar Y.Zeng B.X.Zhang Guangyi Zhang H.Zhang H.H.Zhang H.Y.Zhang J.J.Zhang J.L.Zhang J.Q.Zhang J.W.Zhang J.Y.Zhang J.Z.Zhang Jianyu Zhang Jiawei Zhang L.Q.Zhang Lei Zhang S.Zhang S.F.Zhang Shulei Zhang X.D.Zhang X.Y.Zhang Y.Zhang Y.H.Zhang Y.T.Zhang Yan Zhang Yao Zhang Yi Zhang Z.H.Zhang Z.Y.Zhang G.Zhao J.Zhao J.Y.Zhao J.Z.Zhao Lei Zhao Ling Zhao M.G.Zhao Q.Zhao S.J.Zhao Y.B.Zhao Y.X.Zhao Z.G.Zhao A.Zhemchugov B.Zheng J.P.Zheng Y.Zheng Y.H.Zheng B.Zhong C.Zhong L.P.Zhou Q.Zhou X.Zhou X.K.Zhou X.R.Zhou A.N.Zhu J.Zhu K.Zhu K.J.Zhu S.H.Zhu T.J.Zhu W.J.Zhu W.J.Zhu Y.C.Zhu Z.A.Zhu B.S.Zou J.H.Zou 2021Chinese Physics C2021,45,2:33

4Mycoplasma infections and different human carcinomas显示文摘AIM To explore relationships between human carcinomas and mycoplasma infection.METHODS Monoclonal antibody PD4, which specifically recognizes a distinct protein from mycoplasma hyorhinis, was used to detect mycoplasma infection in different paraffinembedded carcinoma tissues with immunohistochemistry. PCR was applied to amplify the mycoplasma DNA from the positive samples for confirming immunohistochemistry.RESULTS Fifty of 90 cases (56%) of gastric carcinoma were positive for mycoplasma hyorhinis. In other gastric diseases, the mycoplasma infection ratio was 28% (18/49) in chronic superficial gastritis, 30% (14/ 46) in gastric ulcer and 37% (18/ 49) in intestinal metaplasia. The difference is significant with gastric cancer (X2=12.06, P<0.05). In colon carcinoma, the mycoplasma infection ratio was 55.1% (32/58), but it was 20.9% (10/49) in adenomarous polyp (X2=13.46, P<0.005).Gastric and colon cancers with high differentiation had a higher mycoplasma infection ratio than those with low differentiation (P< 0.05). Mycoplasma infection in esophageal cancer, lung cancer, breast cancer and glioma was 50.9% (27/53), 52.6% (31/ 59), 39.7%(25/63) and 41% (38/91), respectively. The mycoplasma DNA was successfully amplified with the DNA extracted from the cancer tissues that were positive for mycoplasma infection (detected with antibody PD4).CONCLUSION There was high correlation between mycoplasma infection and different cancers, which suggests the possibility of an association between the two. The mechanism involved in oncogenesis by mycoplasma remains unknown.Su Huang Ji You Li Jan Wu Lin Meng Cheng Chao Shou Beijing Institute for Cancer Research, Peking University School of Oncology, Beijing 100034.

6Research progress on electrical signals in higher plants显示文摘This review introduces the characteristics of electrical signals in higher plants and their corresponding physiological significance, and describes in detail the impact of environmental factors (e.g. light and temperature) on the electrical potential of the plants. Also, we evaluate the measurement techniques used for electrical signals in plants, including intracellular measurement, extracellular measurement, measurement of the ion channel based on the patch-clamp technique and on the non-invasive microelectrode vibrating probe technique. We also give a brief review of the applications of these methods for investigating electrical signals in plants. The ionic mechanism of electrical activity in plants is then discussed in terms of environmental response in higher plants, and this is used to provide a theoretical basis for quantitative description of the electrical signals in plants. A model for interpretation of the electrical signal mechanisms in higher plants is discussed, but further experiments are required for the verification of this model.Xiaofei Yana, Zhongyi Wang a, Lan Huang a, Cheng Wang b, Ruifeng Hou b, Zhilong Xu b, Xiaojun Qiao b a College of Information and Electrical Engineering, China Agricultural University, Beijing 100083, China b National Engineering Research Center for Information Technology in Agriculture, Beijing 100097, China 2009Progress in Natural Science:Materials International2009,19,5:13
7Optimization of Short Stroke Control Preset for Automatic Width Control of Hot Rolling Mill显示文摘Automatic width control is a key issue in hot strip rolling process. The edge rolling has been widely used in the roughing stand of hot strip mill to control the width of the slab. However, the edge rolling and consequent horizontal rolling will cause a significant width change in the head part and tail part of the slab, which have to be trimmed before the finishing stands. Based on the width reduction deformation curve of the head and tail along the longitudinal direction of slab, the short stroke control (SSC) technology has been developed to overcome this problem. The finite element method has been used to simulate the unsteady edge rolling process. Three short stroke control curves have been compared in order to obtain the best width control result. The optimized short stroke control curve has been applied to the automatic width control system of industrial hot rolling mill,and good performance is obtained.DU Xiao-zhong YANG Quan LU Cheng WANG Ai-li Tieu A Kiet 2010Journal of Iron and Steel Research(International)2010,17,6:12
8Protective effect of early enteral feeding on postburn impairment of liver function and its mechanism in rats显示文摘AIM To study the protective effect of earlyenteral feeding(EEF)on the postburnimpairment of liver function and its mechanism.METHODS Wistar rats with 30% of total bodysurface area(TBSA)full-thickness burn wereemployed.The effects of EEF on the postburnchanges of gastric intramucosal pH,endotoxinlevels in portal vein,water contents of hepatictissue,blood concentrations of tumor necrosisfactor(TNF-α),plasma activities of alanineaminotransferase(ALT)and asparateaminotransferase(AST),as well as the bloodcontents of total(TB)and direct bilirubin(DB),total protein(TP)and albumin(ALB)wereserially determined within 48h postburn.RESULTS EEF could significantly improvegastric mucosal acidosis,reduce portal veinendotoxin level and water content of hepatictissue,as well as plasma concentrations of TNF-α at all timepoints after severe burns(P<0.01);postburn elevation of the plasma activities ofALT,AST and the contents of TB,DB wereeffectively prevented,whereas the plasmaconcentrations of TP and ALB were markedlyincreased 24 h and 48 h posturn in EEF groupcompared with that of the burn without EEFgroup(P<0.01).CONCLUSION EEF has significant beneficialeffects on the improvement of hepatic function in rats after severe burn,and is probably relatedwith an increase in splanchnic blood flow,reduction of the absorption of gut-originendotoxin and the consequent release ofinflammatory mediators.Zhu L Yang ZC Li A Cheng DC 2000World Journal of Gastroenterology2000,6,1:10

10Reaction decoupling in thermochemical fuel conversion and technical progress based on decoupling using fluidized bed显示文摘Thermochemical conversion of fuels via pyrolysis/carbonization,cracking,gasification and combustion has to involve a number of individual reactions called attribution reactions to form an intercorrelated reaction network for any conversion process.By separating one or some attribution reactions from the others to decouple their interactions existing in the reaction network,the so-called reaction decoupling enables a better understanding of the complex thermal conversion process and further the optimization of the conditions for attribution reactions as well as the entire conversion process to realize advanced performances.The dual bed conversion and two-stage conversion are the two representative types of fuel conversion technologies developed in recent years based on reaction decoupling.Many technical advantages have been proven for such decoupling fuel conversion technologies,such as poly-generation of products,low-cost production of high-grade products,elimination of undesirable products or pollutants,easy operation and control,and so on.The treated fuels with decoupling conversion technologies mainly include solid biomass and coal,as well as liquid petroleum oil.This paper is devoted to reiteration of the reaction decoupling concept and further to reviewing the research,developments and successful applications of several decoupling fuel conversion technologies of two such types by using fluidized bed as their major reactors.Zhennan Han Sulong Geng Xi Zeng Shipei Xu a Ping An Jiguang Cheng Jun Yang Feng Li Suyi Zhang Miao Liu Guoqing Guan Guangwen Xu 2018Carbon Resources Conversion2018,1,2:8
11Transretinoic acid inhibits rats gastric epithelial dysplasia induced by N-methyi-N-nitro-N-nitrosoguanidine:influences on cell apoptosis and expression of its regulatory genes显示文摘INTRODUCTIONGastric epithelial dysplasia (GED) hypothetically is a straight-forward concept: dysplastic epithelium replacing the normal gastric epithelium of the stomach [1].In the stomach ,like any other segment of the gut ,it is defined as an unequivocal non-invasive epithelial change[2,3].The observation of gastric dysplasia as a cancerous lesion was recognized over a century ago ,but it is only after the advent of gastroscopy that its clinical significance has been stressed[4-7].Ru Tao Cui~1 Gan Cai~2 Zhao Bao Yin~(2*) Yong Cheng~2 Qiu Hong Yang~1 Tao Tian~(3#) ~1Liver Center,Beijing Friendship Hospital Affiliated to CapitalUniversity of Medical Sciences~2Department of Gastroenterology,Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine,Shanghai China and Department of Pathophysiology.Shanghai Medical University.Shanghai,China ~3Pathological Department,Shanghai Medical University (?)Now working at UCLA,USA ~#Now working at University of Michigan,USADr.Ru Tao Cui graduated and got the bachelor degree from Shandong University of Traditional Chinese Medicine in 1994,got doctor degree from Shanghai University of Traditional Chinese Medicine in 2000,now studying as a postdoc,majoring gastroenterology,having 29 papers published. 2001World Journal of Gastroenterology2001,7,3:8
12Microsecond scale vibrational spectroscopic imaging by multiplex stimulated Raman scattering microscopy显示文摘Real-time vibrational spectroscopic imaging is desired for monitoring cellular states and cellular processes in a label-free manner.Raman spectroscopic imaging of highly dynamic systems is inhibited by relatively slow spectral acquisition on millisecond to second scale.Here,we report microsecond scale vibrational spectroscopic imaging by lock-in free parallel detection of spectrally dispersed stimulated Raman scattering signal.Using a homebuilt tuned amplifier array,our method enables Raman spectral acquisition,within the window defined by the broadband pulse,at the speed of 32 μs and with close to shot-noise limited detection sensitivity.Incorporated with multivariate curve resolution analysis,our platform allows compositional mapping of lipid droplets in single live cells,observation of intracellular retinoid metabolism,discrimination of fat droplets from protein-rich organelles in Caenorhabditis elegans,spectral detection of fast flowing tumor cells and monitoring drug diffusion through skin tissue in vivo.The reported technique opens new opportunities for compositional analysis of cellular compartment in a microscope setting and high-throughput spectral profiling of single cells in a flow cytometer setting.Chien-Sheng Liao Mikhail N Slipchenko Ping Wang Junjie Li Seung-Young Lee Robert A Oglesbee Ji-Xin Cheng 2015Light(Science & Applications)2015,4,1:8

14Reduced gastric acid production in burn shock period and its significance in the prevention and treatment of acute gastric mucosal lesions显示文摘AIM To investigate the changes of gastric acidproduction and its mechanism in shock period ofsevere burn in rats.METHODS A rat model with 30% TBSA full-thickness burn injury was employed and thegastric acid production,together with gastricmucosal blood flow(GMBF)and energy charge(EC)were measured serially within 48hpostburn.RESULTS The gastric acid production in theacute shock period was markedly inhibited aftersevere burn injury.At the 3rd h postburn,thegastric juice volume,total acidity and acidoutput were already significantly decreased(P<0.01),and reached the lowest point,0.63mL/L±0.20mL/L,10.81mmol/L±2.58mmol/L and 2.23mmol/h±0.73mmol/hrespectively,at the 12th h postburn.Althoughrestored to some degree 24 h after thermalinjury,the variables above were stillstatistically lower,compared with those ofcontrol animals at the 48th h postburn.TheGMBF and EC were also significantly reducedafter severe burns,consistent with the trend ofgastric acid production changes.CONCLUSION Gastric acid production,as wellas GMBF and EC was predominantly decreased in the early postburn stage,suggesting that gastricmucosal ischemia and hypoxia with resultantdisturbance in energy metabolism,but notgastric acid proper,might be the decisive factorin the pathogenesis of AGML after thermalinjury,and that the preventive use of anti-aciddrugs during burn shock period wasunreasonable in some respects.Therefore,taking effective measures to improve gastricmucosal blood perfusion as early as possiblepostburn might be more preferable for the AGMLprevention and treatment.Zhu L Yang ZC Li A Cheng DC 2000World Journal of Gastroenterology2000,6,1:7

16Effects of disinhibition on spatiotemporal pattern of neuronal first recruitment in neuronal networks显示文摘The propagation of neuronal activities is a key feature to understanding information processing in networks. The analysis based on first-spikes of bursts in turn plays an important role in the research of neuronal activity propagation. Our focus here is to investigate how spatiotemporal patterns of neuronal first-spikes are affected by disinhibition. Multi-electrode arrays were used to record stimulation-evoked bursts of multiple neurons in randomly cultured neuronal networks. Both the precise timing of and the rank relationships between first-spikes were analyzed. Compared with evoked bursts in the network's native state, the precise first-spike latencies in its dis-inhibited state are more consistent and the propagation of its bursting activities is much faster. Additional points of interest are that disinhibited neuronal networks can be evoked to generate stable and distinguishable neuronal first recruitment spatiotemporal patterns specific to the stimulation site, and that the disinhibition may cause the original spatiotemporal patterns to change in a heterogeneous manner with regards to different propagation pathways.Liangbin Pana,b,c,1, Xindong Songa,b,c,1, Guangxin Xiang a,b,c, Jing Zhua,b,c, Jing Cheng a,b,c,d,a Medical Systems Biology Research Center, Tsinghua University School of Medicine, Beijing 100084, China b Department of Biological Sciences and Biotechnology, Tsinghua University, Beijing 100084, China c National Engineering Research Center for Beijing Biochip Technology, 18 Life Science Parkway, Beijing 102206, China d State Key Laboratory of Biomembrane and Membrane Biotechnology, Tsinghua University, Beijing 100084, China 2009Progress in Natural Science:Materials International2009,19,5:6
17Age and menopausal status are important factors influencing the serum human epididymis secretory protein 4 level:a prospective cross-sectional study in healthy Chinese people显示文摘Background::Human epididymis secretory protein 4(HE4)is a new ovarian cancer biomarker.The factors influencing HE4 levels are not clear,and the reference data in China are limited.Here,we aim to evaluate the effects of menopause and age on HE4 levels and to provide a possible reference value for HE4 in healthy Chinese people.Methods::A total of 2493 healthy females aged 40 years or older were recruited from March 2013 to March 2017 with the cooperation of four medical institutions across Beijing,China.The serum levels of HE4 and cancer antigen 125(CA125)were measured by enzyme-linked immunosorbent assay.The Wilcoxon rank-sum test of variance and a stratified analysis were used to analyze the relationships among age,menopausal status,and levels of HE4 or CA125.Confidence intervals(5%-95%)were determined for reference ranges in different populations.Results::There was a statistically significant difference in median HE4 levels between the post-menopausal(n=2168)and premenopausal groups(n=325)(36.46 vs.24.04 pmol/L,Z=-14.41,P<0.001).HE4 increased significantly with age in the post-menopausal groups(H=408.18,P<0.001)but not in the pre-menopausal subjects(Z=-0.43,P=0.67).The upper 95th percentile of HE4 levels were 44.63 pmol/L for pre-menopausal women,78.17 pmol/L for post-menopausal women,and 73.3 pmol/L for all women.In the post-menopausal population,the HE4 reference ranges were 13.15 to 47.31,14.31 to 58.04,17.06 to 73.51,24.50 to 115.25,and 35.71 to 212.37 pmol/L for different age groups from forty divided by decade.The CA125 level was affected mainly by menopausal status and not age.Conclusions::Menopausal status and age were both important factors influencing the level of HE4,and age affected HE4 levels mainly in post-menopausal women.The HE4 level was higher in the post-menopausal population than in the pre-menopausal population and increased with age.Hong-Yan Cheng Lin Zeng Xue Ye Rui-Qiong M a Zhi-Jian Tang Hong-Ling Chu Yi-M ing Zhao Li-Rong Zhu Yu-Nong Gao Xiao-Hong Chang Heng Cui 2020Chinese Medical Journal2020,,11:6

19Pancreatitis after endoscopic retrograde cholangiopancreatography:A narrative review显示文摘Acute post-endoscopic retrograde cholangiopancreatography pancreatitis(PEP)is a feared and potentially fatal complication that can be as high as up to 30%in high-risk patients.Pre-examination measures,during the examination and after the examination are the key to technical and clinical success with a decrease in adverse events.Several studies have debated on the subject,however,numerous topics remain controversial,such as the effectiveness of prophylactic medications and the amylase dosage time.This review was designed to provide an update on the current scientific evidence regarding PEP available in the literature.Igor Braga Ribeiro Epifanio Silvino do Monte Junior Antonio Afonso Miranda Neto Igor Mendonça Proença Diogo Turiani Hourneaux de Moura Mauricio Kazuyoshi Minata Edson Ide Marcos Eduardo Lera dos Santos Gustavo de Oliveira Luz Sergio Eiji Matuguma Spencer Cheng Renato Baracat Eduardo Guimarães Hourneaux de Moura 2021World Journal of Gastroenterology2021,27,20:5
