1A study of the efficacy of bacterial biofilm cleanout for gastrointestinal endoscopes显示文摘AIM:To compare the influence and clearance effect of enzymatic and non-enzymatic detergents against Escherichia coli (E. coli) biofilm on the inner surface of gastroscopes.METHODS:Teflon tubes were incubated in a mixture of different detergents and E. coli culture (106 CFU/mL) for 72 h at 15℃,and biofilms on the inner surface of the teflon tubes were analyzed by bacterial count and scanning electron microscopy. To evaluate the clear-ance effect of detergents,after biofilms were formed on the inner surface of Teflon tubes by 72 h lavage with E. coli culture,tubes were lavaged by enzymatic and non-enzymatic detergents at a speed of 250 mL/min,then biofilms on the inner surface were analyzed by bacterial count and scanning electron microscopy.RESULTS:Non-enzymatic detergent had a better inhi-bition function on biofilm formation than enzymatic de-tergent as it reduced bacterial burden by 2.4 log compared with the control samples (P = 0.00). Inhibition function of enzymatic detergent was not significantly different to that of control samples and reduced bac-terial burden by 0.2 log on average (P > 0.05). After lavaging at 250 mL/min for 3 min,no living bacteria were left in the tubes. Scanning electron microscopy observation showed biofi lms became very loose by the high shear force effect. CONCLUSION:Non-enzymatic detergent has a better inhibition effect on biofilm formation at room temperature. High speed pre-lavage and detergents are very important in temporal formed biofilm elimination.Fang, Ying Shen, Zhe Li, Lan Cao, Yong Gu, Li-Ying Gu, Qing Zhong, Xiao-Qi Yu, Chao-Hui Li, You-Ming 2010World Journal of Gastroenterology2010,16,8:28
2Effects of probiotics on nonalcoholic fatty liver disease:A meta-analysis显示文摘AIM:To investigate the relationship between the gutliver axis and nonalcoholic fatty liver disease(NAFLD),we performed a meta-analysis to evaluate the effects of probiotic therapy in NAFLD.METHODS:We searched PubMed,Medline,Embase,Web of Science,the Cochrane Library and Chinese Biomedicine Database for all relevant randomized controlled trials on probiotics in patients with NAFLD/nonalcoholic steatohepatitis(NASH).A statistical analysis was performed using RevMan 5.0 software.RESULTS:Four randomized trials involving 134 NAFLD/NASH patients were included.The results showed that probiotic therapy signifcantly decreased alanine aminotransferase(ALT),aspartate transaminase(AST),total-cholesterol(T-chol),high density lipoprotein(HDL),tumor necrosis factor(TNF)-αand homeostasis model assessment of insulin resistance(HOMAIR)[ALT:weighted mean difference(WMD)-23.71,95%CI:-33.46--13.95,P<0.00001;AST:WMD-19.77,95%CI:-32.55--7.00,P=0.002;T-chol:WMD-0.28,95%CI:-0.55--0.01,P=0.04;HDL:WMD-0.09,95%CI:-0.16-0.01,P=0.03;TNF-α:WMD-0.32,95%CI:-0.48--0.17,P<0.0001;HOMA-IR:WMD-0.46,95%CI:-0.73--0.19,P=0.0008].However,the use of probiotics was not associated with changes in body mass index(BMI),glucose(GLU)and low density lipoprotein(LDL)(BMI:WMD 0.05,95%CI:-0.18-0.29,P=0.64;GLU:WMD 0.05,95%CI:-0.25-0.35,P=0.76;LDL:WMD-0.38,95%CI:-0.78-0.02,P=0.06).CONCLUSION:Probiotic therapies can reduce liver aminotransferases,total-cholesterol,TNF-αand improve insulin resistance in NAFLD patients.Modulation of the gut microbiota represents a new treatment for NAFLD.Yan-Yan Ma Lin Li Chao-Hui Yu Zhe Shen Li-Hua Chen You-Ming Li 2013World Journal of Gastroenterology2013,19,40:28
3Risk factors for alcohol-related liver injury in the island population of China: A population-based case-control study显示文摘AIM:To investigate the association of alcohol dose, duration of drinking and obesity with abnormal alcohol-related liver injury indicators, the prevalence of alcohol-related liver injury in the island population of China.METHODS:Randomized multistage stratified cluster sampling from the island population of China was used in the population-based case-control study. Then interview, physical examination, laboratory assessments and ultrasonography were done. RESULTS:Daily alcohol intake ≥ 20 g, duration of drinking ≥ 5 years and obesity were closely related to alcohol-related liver injury (P < 0.05). The odds-ratio (OR) (95% CI) was 1.965 (1.122-3.442), 3.412 (1.789-6.507) and 1.887 (1.261-2.824), respectively. The prevalence rate of alcohol-related liver injury in ≥ 20 g daily alcohol intake group and < 20 g daily alcohol intake group was 37.14% and 12.06%, respectively. The prevalence rate of alcohol-related liver injury in ≥ 5 years drinking group and < 5 years drinking group was 34.44% and 8.53%, respectively. No significant dose-response relation was found between daily alcohol intake and abnormal alcohol-related liver injury indicators as well as between duration of drinking and abnormal alcohol-related liver injury indicators. There was no significant difference in the prevalence of alcohol-related liver injury between beer drinking group and yellow rice wine drinking group, hard liquor drinking group, multiple drinking group.CONCLUSION:The risk threshold of daily alcohol intake is 20 g and duration of drinking inducing alcohol-related liver injury 5 years in the island population of China. Liver injury induced by obesity should be concerned.Zhe Shen You-Ming Li Chao-Hui Yu Yi Shen Lei Xu Cheng-Fu Xu Jin-Jin Chen Hua Ye Gen-Yun Xu 2008World Journal of Gastroenterology2008,14,14:28

5N6-Methyladenine DNA Methylation in Japonica and Indica Rice Genomes and Its Association with Gene Expression,Plant Development, and Stress Responses显示文摘N6-Methyladenine (6mA)DNA methylation has recently been implicated as a potential new epigenetic marker in eukaryotes,including the dioot modelArabidopsis thaliana.However,the conservation and divergence of 6mA distribution patterns and functions in plants remain elusive.Here we report high-quality 6mA methylomes at single-nucleotide resolution in rice based on substantially improved genome sequences of two rice cultivars,Nipponbare (Nip;Japonica)and 93-11 (Indica).Analysis of 6mA genomic distribution and its association with transcription suggest that 6mA distribution and function is rather conserved between rice and Arabidopsis.We found that 6mA levels are positively correlated with the expression of key stressrelated genes,which may be responsible for the difference in stress tolerance between Nip and 93-11. Moreover,we showed that mutations in DDM1 cause defects in plant growth and decreased 6mA level. Our results reveal that 6mA is a conserved DNA modification that is positively associated with gene expression and contributes to key agronomic traits in plants.Qian Zhang Zhe Liang Xuean Cui Changmian Ji Yun Li Pingxian Zhang Jingrong Liu Adeel Riaz Pu Yao Min Liu Yunpeng Wang Tiegang Lu Hao Yu Donglei Yang Hongkun Zheng Xiaofeng Gu 2018Molecular Plant2018,11,12:18
6Exploring an Integrative Therapy for Treating COVID-19:A Randomized Controlled Trial显示文摘Objectives:To develop a new Chinese medicine(CM)-based drug and to evaluate its safety and effect for suppressing acute respiratory distress syndrome(ARDS)in COVID-19 patients.Methods:A putative ARDS-suppressing drug Keguan-1 was first developed and then evaluated by a randomized,controlled two-arm trial.The two arms of the trial consist of a control therapy(alpha interferon inhalation,50(x g twice daily;and lopinavir/ritonavir,400 and 100 mg twice daily,respectively)and a testing therapy(control therapy plus Keguan-119.4 g twice daily)by random number table at 1:1 ratio with 24 cases each group.After 2-week treatment,adverse events,time to fever resolution,ARDS development,and lung injury on newly diagnosed COVID-19 patients were assessed.Results:An analysis of the data from the first 30 participants showed that the control arm and the testing arm did not exhibit any significant differences in terms of adverse events.Based on this result,the study was expanded to include a total of 48 participants(24 cases each arm).The results show that compared with the control arm,the testing arm exhibited a significant improvement in time to fever resolution(P=0.035),and a significant reduction in the development of ARDS(P=0.048).Conclusions:Keguan-1-based integrative therapy was safe and superior to the standard therapy in suppressing the development of ARDS in COVID-19 patients.(Trial registration No.NCT 04251871 at www.clinicaltrials.gov).WANG Jia-bo WANG Zhong-xia JING Jing ZHAO Peng DONG Jing-hui ZHOU Yong-feng YANG Guang NIU Ming ZHAO Xu JIANG Tian-jun Bl Jing-feng XU Zhe ZHANG Ping WU Dan BAI Zhao-fang GUO Yu-ming YU Si-miao SUN Yong-qiang ZHANG Zi-teng ZHAN Xiao-yan LI Peng-yan DING Jin-biao ZHAO Peng-fei SONG Xue-ai TANG Jian-yuan HE Dong-chu CHEN Zhu QIN En-qiang WANG Rui-lin XIAO Xiao-he 2020Chinese Journal of Integrative Medicine2020,26,9:18

10Vascular endothelial growth factor concentration in vitreous humor of patients with severe proliferative diabetic retinopathy after intravitreal injection of conbercept as an adjunctive therapy for vitrectomy显示文摘Background:Proliferative diabetic retinopathy(PDR)is a progressive stage of diabetic retinopathy featured by the formation of neovascular and proliferative membrane.Vascular endothelial growth factor(VEGF)acts as a pivot factor in the development of neovascularization.This study was to investigate the changes of intravitreal VEGF concentrations of severe PDR after intravitreal injection of conbercept(IVC)and its potential advantages to the following vitrectomy.Methods:This was a prospective,interventional,randomized controlled study.Sixty eyes(60 patients)with severe PDR and 20 eyes from 20 patients with rhegmatogenous retinal detachment complicated with proliferative vitreoretinopathy were enrolled in this study.PDR eyes were randomly assigned to three groups by sortation randomization method with 20 eyes in each based on the interval of preoperative IVC(group A:7 days,group B:14 days,group C:non-IVC).Another 20 eyes without diabetes were enrolled as the non-diabetic control group(group D),receiving PPV directly.Vitreous specimens of all 80 patients were collected and evaluated afterwards.The intravitreal VEGF concentration of the four groups,and the total surgical time and the intraoperative bleeding rate of the PDR groups were recorded.Results:The mean intravitreal VEGF concentrations of groups A-D were 66.6±43.3,93.1±52.3,161.4±106.1 and 1.8±1.2 pg/mL,respectively.It increased significantly in PDR patients(groups A,B and C)(P=0.002,<0.001,and<0.001,respectively).PDR patients with preoperative IVC(groups A and B)presented significantly lower VEGF concentrations(P<0.001 and 0.001),intraoperative bleeding rates(P=0.004)and total surgical time(P<0.001,P=0.003)compared with group C.No statistical differences were presented between groups A and B on the three parameters.Conclusion:Seven days and 14 days of preoperative IVC are equally efficient and safe for the vitrectomy of severe PDR patients through decreasing vitreous VEGF concentrations,intraoperative bleeding rate and total surgical times.Bing Li Meng-Da Li Jun-Jie Ye Zhe Chen Zi-Jian Guo Yu Di 2020Chinese Medical Journal2020,,6:14
11High HIV incidence epidemic among men who have sex with men in china: results from a multi-site cross-sectional study显示文摘Background:Recent upsurge of new HIV infections among men who have sex with men(MSM)is a major concern in China.Paucity of national-level information regarding the burden and predictors of this progressive epidemic of new infections called for a multi-centric,timely and comprehensive investigation.Methods:Mixed methods were used to recruit MSM from seven cities in China between 2012 and 2013.Recent and established HIV infections were estimated by Western Blot and BED HIV-1 capture enzyme immunoassay.Syphilis and herpes simplex virus-2(HSV-2)were also tested.Results:A total of 4496 eligible MSM were recruited.The majority was aged≤35 years(77.5%),migrants(60.3%),never married(69.8%),and played receptive role in anal sex(70.5%).The HIV prevalence was 9.9%,and 41.9%were recently infected,with sensitivity/specificity adjusted HIV incidence of 8.9(95%CI:7.6-10.2)/100 Person-Years.The prevalence of history HSV-2 and syphilis were 12.5%and 8.5%,respectively.Recent HIV infection was associated with having multiple male partners(aOR=1.4,95%CI 1.1-1.9),recreational drug use(aOR=2.2,95%CI 1.6-3.0),anal bleeding(aOR=2.1,95%CI 1.4-3.0),syphilis infection(aOR=2.8,95%CI 1.9-4.3)and history HSV-2 infection(aOR=2.3,95%CI 1.5-3.3).Conclusion:High rate of recent HIV infection is potentially resulting in progressive deterioration of the overall HIV epidemic among MSM in China.Targeted interventions to address high-risk MSM including those having multiple partners,history of recreational drug use and syphilis or HSV-2 infection seemed to be the need of the hour.Jun-Jie Xu Wei-Ming Tang Hua-Chun Zou Tanmay Mahapatra Qing-Hai Hu Geng-Feng Fu Zhe Wang Lin Lu Ming-Hua Zhuang Xi Chen Ji-Hua Fu Yan-Qiu Yu Jin-Xin Lu Yong-Jun Jiang Wen-Qing Geng Xiao-Xu Han Hong Shang 2016Infectious Diseases of Poverty2016,5,1:14

13CXCR7/CXCL12 axis is involved in lymph node and liver metastasis of gastric carcinoma显示文摘AIM To investigate the role of CXC chemokine receptor(CXCR)-7 and CXCL12 in lymph node and liver metastasis of gastric carcinoma.METHODS In 160 cases of gastric cancer, the expression of CXCR7 and CXCL12 in tumor and matched tumoradjacent non-cancer tissues, in the lymph nodes around the stomach and in the liver was detected using immunohistochemistry to analyze the relationship between CXCR7/CXCL12 expression and clinicopathological features and to determine whether CXCR7 and CXCL12 constitute a biological axis to promote lymph node and liver metastasis of gastric cancer. Furthermore, the CXCR7 gene was silenced and overexpressed in human gastric cancer SGC-7901 cells, and cell proliferation, migration and invasiveness were measured by the MTT, wound healing and Transwell assays, respectively. RESULTS CXCR7 expression was up-regulated in gastric cancer tissues(P = 0.011). CXCR7/CXCL12 expression was significantly related to poor tumor differentiation, high tumor stage and lymph node(r = 0.338, P = 0.000) and liver metastasis(r = 0.629, P = 0.000). The expression of CXCL12 in lymph node and liver metastasis was higher than that in primary gastric cancer tissues(χ2 = 6.669, P = 0.010; χ2 = 25379, P = 0.000), and the expression of CXCL12 in lymph node and liver metastasis of gastric cancer was consistent with the positive expression of CXCR7 in primary gastric cancer(r = 0.338, P = 0.000; r = 0.629, P = 0.000). Overexpression of the CXCR7 gene promoted cell proliferation, migration and invasion. Silencing of the CXCR7 gene suppressed SGC-7901 cell proliferation, migration and invasion. Human gastric cancer cell lines expressed CXCR7 and showed vigorous proliferation and migratory responses to CXCL12.CONCLUSION The CXCR7/CXCL12 axis is involved in lymph node and liver metastasis of gastric cancer. CXCR7 is considered a potential therapeutic target for the treatment of gastric cancer.Qi Xin Na Zhang Hai-Bo Yu Qin Zhang Yan-Fen Cui Chuan-Shan Zhang Zhe Ma Yan Yang Wei Liu 2017World Journal of Gastroenterology2017,23,17:14
14PCA3 and TMPRSS2-ERG gene fusions as diagnostic biomarkers for prostate cancer显示文摘The incidence of prostate cancer(PCa) is rising steadily among males in many countries. Serum prostate-specific antigen(PSA) is widely applied to clinical diagnosis and screening of PCa. However, the so-called grey area of PSA levels 4.0–10.0 ng/m L has a low specificity of 25–40% resulting in a high rate of negative biopsy and overtreatment. So in order to treat PCa patients in early stage, there is an urgent need for new biomarkers in PCa diagnosis. The PCA3 gene, a non-coding RNA(nc RNA) that is highly expressed in prostate cancer(PCa) cells, has been identified as a molecular biomarkers to detect PCa, of which PCA3 has already under clinical application. PCA3 is strongly overexpressed in malignant prostate tissue compared to benign or normal adjacent one. Newly, PCA3 is considered to be a promising biomarker in clinical diagnosis and targeted therapy. The diagnostic significance of PCA3, however, is awaiting further researches. Moreover, it has been demonstrated recently that TMPRSS2-ERG gene fusion is identified as the predominant genetic change in patients diagnosed with PCa. Recent study revealed that combination of the PCA3 and TMPRSS2-ERG gene fusion test optimizes PCa detection compared with that of single biomarker, which would lead to a considerable reduction of the number of prostate biopsies. In this review, we focused on the potential use of PCA3 and TMPRSS2-ERG gene fusion detection in the diagnosis of PCa.Zheng Yang Lu Yu Zhe Wang 2016Chinese Journal of Cancer Research2016,28,1:13
15Effect of human umbilical cord-derived mesenchymal stem cells on lung damage in severe COVID-19 patients:a randomized,double-blind,placebo-controlled phase 2 trial显示文摘Treatment of severe Coronavirus Disease 2019(COVID-19)is challenging.We performed a phase 2 trial to assess the efficacy andsafety of human umbilical cord-mesenchymal stem cells(UC-MScs)to treat severe coViD-19 patients with lung damage,based onour phase 1 data.In this randomized,double-blind,and placebo-controlled trial,we recruited 101 severe coVID-19 patients withlung damage.They were randomly assigned at a 2:1 ratio to receive either UC-MSCs(4×10^(7)cells per infusion)or placebo on day 0,3,and 6.The primary endpoint was an altered proportion of whole lung lesion volumes from baseline to day 28.Other imagingoutcomes,6-minute walk test(6-MWT),maximum vital capacity,diffusing capacity,and adverse events were recorded and analyzed.In all,100 COVID-19 patients were finally received either UC-MSCs in=65)or placebo(n=35).UC-MSCs administrationexerted numerical improvement in whole lung lesion volume from baseline to day 28 compared with the placebo(the mediandifference was-13.31%,95%Cl-29.14%,2.13%,P=0.08).UC-MSCs significanty reduced the proportions of solid componentlesion volume compared with the placebo(median difference:-15.45%;95%CI-30.82%,-0.39%;P=0.043).The 6-MWT showedan increased distance in patients treated with UC-MSCs(difference:27.00 m;95%CI 0.00,57.00;P=0.057).The incidence of adverseevents was similar in the two groups.These results suggest that UC-MSCs treatment is a safe and potentially effective therapeuticapproach for COVID-19 patients with lung damage.A phase 3 trial is required to evaluate effects on reducing mortality andpreventing long-term pulmonary disability.Lei Shi Hai Huang Xuechun Lu Xiaoyan Yan Xiaojing Jiang Ruonan Xu Siyu Wang Chao Zhang Xin Yuan Zhe Xu Lei Huang Jun-Liang Fu Yuanyuan Li Yu Zhang Wei-Qi Yao Tianyi Liu Jinwen Song Liangliang Sun Fan Yang Xin Zhang Bo Zhang Ming Shi Fanping Meng Yanning Song Yongpei Yu Jiqiu Wen Qi Li Qing Mao Markus Maeurer Alimuddin Zumla Chen Yao Wei-Fen Xie Fu-Sheng Wang 2021Signal Transduction and Targeted Therapy2021,6,3:13

17m^6A-dependent biogenesis of circular RNAs in male germ cells显示文摘The majority of circular RNAs(circRNAs)spliced from coding genes contain open reading frames(ORFs)and thus,have protein coding potential.However,it remains unknown what regulates the biogenesis of these ORF-containing circRNAs,whether they are actually translated into proteins and what functions they play in specific physiological contexts.Here,we report that a large number of circRNAs are synthesized with increasing abundance when late pachytene spermatocytes develop into round and then elongating spermatids during murine spermatogenesis.For a subset of circRNAs,the back splicing appears to occur mostly at m^6A-enriched sites,which are usually located around the start and stop codons in linear mRNAs.Consequently,approximately a half of these male germ cell circRNAs contain large ORFs with m^6A-modified start codons in their junctions,features that have been recently shown to be associated with protein-coding potential.Hundreds of peptides encoded by the junction sequences of these circRNAs were detected using liquid chromatography coupled with mass spectrometry,suggesting that these circRNAs can indeed be translated into proteins in both developing(spermatocytes and spermatids)and mature(spermatozoa)male germ cells.The present study discovered not only a novel role of m^6A in the biogenesis of coding circRNAs,but also a potential mechanism to ensure stable and long-lasting protein production in the absence of linear mRNAs,i.e.,through production of circRNAs containing large ORFs and m^6A-modified start codons in junction sequences.Chong Tang Yeming Xie Tian Yu Na Liu Zhuqing Wang Rebekah J.Woolsey Yunge Tang Xinzong Zhang Weibing Qin Ying Zhang Ge Song Weiwei Zheng Juan Wang Weitian Chen Xiongyi Wei Zhe Xie Rachel Klukovich Huili Zheng David R.Quilici Wei Yan 2020Cell Research2020,30,3:12

19MiR-122-5p suppresses the proliferation, migration, and invasion of gastric cancer cells by targeting LYN显示文摘Gastric cancer(GC)is one of malignant tumors with high mortality and morbidity in the world.MicroRNA-122(miR-122)acts as a tumor suppressor in a variety of cancers and has been found to be dominant in gastric adenocarcinoma.However,the specific biological function of miR-122-5p in GC is not completely clear.In this study,we found that miR-122-5p was low-expressed in GC tissues and cell lines by using qRT-PCR.Overexpression of miR-122-5p inhibited the proliferation,migration,and invasion of GC cells by using CCK-8 and transwell assays.On the contrary,downregulation of miR-122-5p promoted the proliferation,migration,and invasion of GC cells.In addition,we found that the expression of LYN,an Src family tyrosine kinase,was inversely correlated with miR-122-5p expression in GC tissues by using western blot analysis,immunohistochemistry,and qRT-PCR assays.Meanwhile,luciferase assay results indicated that LYN is a direct target of miR-122-5p in GC cells.Moreover,silencing LYN expression by its siRNA inhibited the proliferation,migration,and invasion of GC cells.Importantly,overexpression of LYN restored miR-122-5p-mediated inhibition of the proliferation,migration,and invasion of GC cells.Taken together,our results indicated miR-122-5p inhibited the proliferation,migration,and invasion by targeting LYN in GC.Lei Meng Zhangming Chen Zhe Jiang Ting Huang Jie Hu Panquan Luo Hongli Zhang Mengqi Huang Lei Huang Yu Chen Ming Lu A-man Xu Songcheng Ying 2020Acta Biochimica et Biophysica Sinica2020,52,1:12
20Enhanced Mechanical Properties of Multi-layer Graphene Filled Poly(vinyl chloride) Composite Films显示文摘In order to improve mechanical properties of soft poly(vinyl chloride)(PVC) films,we used commercial multi-layer graphene(MLG) with large size and high structural integrity as reinforcing fillers,and prepared MLG/PVC composite films by using conventional melt-mixing methods.Microstructures,static and dynamic mechanical properties of the MLG/PVC composite films were investigated.The results showed that a small amount of MLG loading could greatly increase the mechanical properties of the MLG/PVC composites.The tensile modulus of the 0.96 wt%MLG/PVC composites was up to 40 MPa,increasing by31.3%in comparison to the neat PVC.Such a significant mechanical reinforcement was mainly attributed to uniform dispersion of the large-size MLG,good compatibility and strong interactions among MLG and plasticizers and PVC.Han Wang Guiyuan Xie Zhe Ying Yu Tong You Zeng 2015Journal of Materials Science & Technology2015,31,4:11
