7Comparison of plasma microRNA-1 and cardiac troponin T in early diagnosis of patients with acute myocardial infarction显示文摘BACKGROUND:Early reperfusion can effectively treat acute myocardial infarction(AMI) and reduce the mortality signif icantly. This study aimed to compare the role of plasma microRNA-1(miR-1) and cardiac troponin T(cTnT) in early diagnosis of AMI patients.METHODS:From May 2011 to May 2012,plasma samples were collected from 56 AMI patients and 28 non-AMI controls. The expression of plasma miR-1 was measured by quantitative reverse transcription-polymerase chain reaction(qRT-PCR),and the level of plasma cTnT was measured using electrochemiluminescence-based methods on an Elecsys 2010 Immunoassay Analyzer. SPSS 16.0 was used for the statistical analysis of the results. Data were expressed as mean±standard deviation unless otherwise described. The differences about clinical characteristics between the AMI patients and controls were tested using Student's t test or Fisher's exact test. The Mann-Whitney U test was conducted to compare the expression of microRNAs between the AMI patients and controls. MicroRNAs expression between different intervals of the AMI patients was compared using Wilcoxon's signed-rank test. The receiver operating characteristic(ROC) curve was established to discriminate the AMI patients from the controls.RESULTS:In the present study,the expression of plasma miR-1 was signifi cantly increased in the AMI patients compared with the healthy controls(P<0.01). The plasma miR-1 in the AMI patients decreased to the normal level at 14 days(P>0.05). The expression of plasma miR-1 was not related to the clinical characteristics of the study population(P>0.05). ROC curve analyses demonstrated that miR-1 was specifi c and sensitive for the early diagnosis of AMI,but not superior to cTnT.CONCLUSION:Plasma miR-1 could be used in the early diagnosis of AMI,but it is similar to cTnT.Li-ming Li Wen-bo Cai Qin Ye Jian-min Liu Xin Li Xiao-xing Liao 2014World Journal of Emergency Medicine2014,5,3:20
8Effect of H pylori infection and its eradication on hyperammo-nemia and hepatic encephalopathy in cirrhotic patients显示文摘AIM: To investigate the relationship between H pylori infection, blood ammonia concentration and hepatic encephalopathy (HE), and the effect of H pylori eradication in cirrhotic patients. METHODS: From July 2003 to January 2005, 457 cirrhotic patients in five regions of Zhejiang Province were enrolled. Patients were evaluated for demographics, number connection test, H pylori infection, liver impairment, blood ammonia concentration and HE. Patients with H pylori infection were given 1 wk therapy with omeprazole plus clarithromycin and tinidazole. 14C urea breath test was performed and mental symptoms and blood ammonia level were reassessed after bacterium eradication. RESULTS: Overall H pylori infection rate was 60.6%, and HE occurred in 47.5% of cirrhotic patients. Subclinical HE (SHE) was detected in 55 of 117 cirrhotic patients. Blood ammonia concentration in H pylori negative (n = 180) and positive (n = 277) cirrhotic patients was 53.8 ± 51.4 and 78.4 ± 63.6 μmol/L, respectively (P < 0.01), which was significantly reduced to 53.5 ± 37.7 μmol/L after bacterium eradication (n = 126) (P < 0.01). Blood ammonia was 97.5 ± 81.0 μmol/L in H pylori -positive cirrhotic patients, and this did not significantly change in those with persistent infection after H pylori eradication (n = 11). HE was more frequently observed in patients with H pylori infection than in those without (58.5% vs 30.6%, P < 0.01). HE rate significantly dropped to 34.1% after H pylori eradiation (P < 0.01). H pylori prevalence significantly differed among cirrhotic patients with HE (74.4%), SHE(69.1%), and those without HE (53.2%) (P < 0.05). Blood ammonia level was significantly different among cirrhotic patients with HE (94.5 ± 75.6 μmol/L), SHE (59.9 ± 49.2 μmol/L), and without HE (47.3 ± 33.5 μmol/L) (P < 0.05). Logistic regression analysis showed that blood ammonia concentration, Child-Pugh stage, upper gastrointestinal bleeding, electrolyte disturbance, and urea nitrogen were risk factors for HE. CONCLUSION: H pylori infection is an important factor for inducing high blood ammonia concentration and HE in cirrhotic patients. H pylori eradication may be helpful for treatment and prevention of HE.Shu-Jie Chen Liang-Jing Wang Qin Zhu Jian-Ting Cai Tao Chen Jian-Min Si 2008World Journal of Gastroenterology2008,14,12:19
9Outcomes of furazolidone-and amoxicillin-based quadruple therapy for Helicobacter pylori infection and predictors of failed eradication显示文摘AIM To evaluate the outcomes of furazolidone-and amoxicillin-based quadruple therapy for treatment of Helicobacter pylori(H. pylori) infection and identify predictors of failed eradication.METHODS Patients with H. pylori infection treated with furazolidone, amoxicillin, bismuth, and proton pump inhibitor therapy(January 2015 to December 2015) who received the ^(13)C-urea breath test > 4 wk after treatment were evaluated. Demographic and clinical data including prior H. pylori treatment attempts, medication adherence, alcohol and cigarette consumption during therapy, and treatment-related adverse events were recorded by reviewing medical records and telephone surveys. H. pylori eradication rates for overall and subgroups were evaluated. Multivariate analysis was performed to identify independent predictors of failed H. pylori eradication.RESULTS Of the 992 patients treated and retested for H. pylori infection, the overall eradication rate was 94.5% [95% confidence interval(CI): 94.1%-95.9%]. H. pylori eradication rate of primary therapy was 95.0%(95%CI: 93.5%-96.5%), while that of rescue therapy was 91.3%(95%CI: 86.8%-95.8%). Among the 859 patients who completed the study protocol, 144(17%) reported treatment-related adverse events including 24(3%) leading to premature discontinuation. On multivariate analysis, poor medication adherence [adjusted odds ratio(AOR) = 6.7, 95%CI: 2.8-15.8], two or more previous H. pylori treatments(AOR = 7.4, 95%CI: 2.2-24.9), alcohol consumption during therapy(AOR = 4.4, 95%CI: 1.5-12.3), and possibly smoking during therapy(AOR = 1.9, 95%CI: 0.9-4.3) were associated with failed H. pylori eradication. CONCLUSION Furazolidone-and amoxicillin-based quadruple therapy for H. pylori infection in an area with a high prevalence of clarithromycin resistance demonstrated high eradication rates as primary and rescue therapies with a favorable safety profile. Patient education targeting abstinence from alcohol during therapy and strict medication adherence may further optimize H. pylori eradication.Ya-Wen Zhang Wei-Ling Hu Yuan Cai Wen-Fang Zheng Qin Du John J Kim John Y Kao Ning Dai Jian-Min Si 2018World Journal of Gastroenterology2018,24,40:18

11COVID-19 Outbreak Caused by Contaminated Packaging of Imported Cold-Chain Products—Liaoning Province,China,July 2020显示文摘Summary What is known about this topic?Few major outbreaks of coronavirus disease 2019(COVID-19)have occurred in China after major nonpharmaceutical interventions and vaccines have been deployed and implemented.However,sporadic outbreaks that had high possibility to be linked to cold chain products were reported in several cities of China..What is added by this report?In July 2020,a COVID-19 outbreak occurred in Dalian,China.The investigations of this outbreak strongly suggested that the infection source was from COVID-19 virus-contaminated packaging of frozen seafood during inbound unloading personnel contact.What are the implications for public health practice?Virus contaminated paper surfaces could maintain infectivity for at least 17–24 days at-25℃.Exposure to COVID-19 virus-contaminated surfaces is a potential route for introducing the virus to a susceptible population.Countries with no domestic transmission of COVID-19 should consider introducing prevention strategies for both inbound travellers and imported goods.Several measures to prevent the introduction of the virus via cold-chain goods can be implemented.Huilai Ma1 Jianqun Zhang Ji Wang Ying Qin Cao Chen Yang Song Liang Wang Jun Meng Lingling Mao Fengqin Li Ning Li Jian Cai Yong Zhang Dayan Wang Yunting Xia Hong Wang Shaofeng Jiang Xiang Zhao Peihua Niu Wenjie Tan Tao Ma Yecheng Yao Naiying Mao Zhen Zhu Tianjiao Ji Qian Yang Baoying Huang Li Zhao Jianxing Yu Li Bai Shuangli Zhu Dongyan Wang Yan Zhang Yingwei Sun Mingchun Luan Yanhai Wang Haibo Sun Shihong Yang Zhijian Bo Xiang Ren Zhongjie Li George Fu Gao Wei Yao Wenqing Yao Zijian Feng Wenbo Xu 2021China CDC weekly2021,3,21:16
12Rhododendron Molle(Ericaceae):phytochemistry,pharmacology,and toxicology显示文摘Rhododendron molle G. Don, belonging to the Ericaceae family, is a traditional Chinese medicinal plant with a wide spectrum of pharmacological effects. This paper aimed to review the phytochemistry, pharmacology and toxicology of R. molle, and to discuss the tendency of future investigations on this plant. A systematic review of literature about R. molle was carried out using resources including classic books about Chinese herbal medicine, and scientific data bases including CNKI, Pubmed, Sci Finder, Scopus, and Web of Science. Over 67 compounds, including diterpenes, triterpenes, flavonoids, and lignans, had been extracted and identified from R. molle. The extracts/monomers isolated from the root, flower and fruits of this plant were used as effective agents for treating pains, inflammatory diseases, hypertension, and pest, etc. In addition, diterpenes, such as rhodojaponin III, were considered as the toxic agents associated with the toxicities of this plant. These findings will be significant for the discovery of new drugs from this plant and full utilization of R. molle.CAI Yong-Qing HU Jian-Hui QIN Jie SUN Tao LI Xiao-Li 2018Chinese Journal of Natural Medicines2018,16,6:16

17Endoscopic submucosal dissection for foregut neuroendocrine tumors:An initial study显示文摘AIM:To evaluate the feasibility and efficacy of endoscopic submucosal dissection(ESD) for foregut neuroendocrine tumors(NETs).METHODS:From April 2008 to December 2010,patients with confirmed histological diagnosis of foregut NETs were included.None had regional lymph node enlargement or distant metastases to the liver or lung on preoperative computerized tomography scanning or endoscopic ultrasonography(EUS).ESD was attempted under general anesthesia.After making several marking dots around the lesion,a mixture solution was injected into the submucosa.The mucosa was incised outside the marking dots.Dissection of the submucosal layer beneath the tumor was performed under direct vision to achieve complete en bloc resection of the specimen.Tumor features,clinicopathological characteristics,complete resection rate,and complications were evaluated.Foregut NETs were graded as G1,G2,or G3 on the basis of proliferative activity by mitotic count or Ki-67 index.All patients underwent regular follow-up to evaluate for any local recurrence or distant metastasis.RESULTS:Those treated by ESD included 24 patients with 29 foregut NETs.The locations of the 29 lesions are as follows:esophagus(n = 1),cardia(n = 1),stomach(n = 23),and duodenal bulb(n = 4).All lesions were found incidentally during routine upper gastrointestinal endoscopy for other indications,and none had symptoms of carcinoid syndrome.Preoperative EUS showed that all tumors were confined to the submucosa.Among the 24 gastric lesions,16 lesions in 11 patients were type I gastric NETs arising in chronic atrophic gastritis with hypergastrinemia,while the other 8 solitary lesions were type Ⅲ because of absence of atrophic gastritis in these cases.All of the tumors were removed in an en bloc fashion.The average maximum diameter of the lesions was 9.4 mm(range:2-30 mm),and the procedure time was 20.3 min(range:10-45 min).According to the World Health Organization 2010 classification,histological evaluation determined that 26 lesions were NET-G1,2 gastric lesions were NET-G2,and 1 esophageal lesion was neuroendocrine carcinoma(NEC).Complete resection was achieved in 28 lesions(28/29,96.6%),and all of them were confined to the submucosa in histopathologic assessment with no lymphovascular invasion.The remaining patient with NEC underwent additional surgery because the resected specimens revealed angiolymphatic and muscularis invasion,as well as incomplete resection.Delayed bleeding occurred in 1 case 3 d after ESD,which was managed by endoscopic treatment.There were no procedure-related perforations.During a mean follow-up period of 24.4 mo(range:12-48 mo),local recurrence occurred in only 1 patient 7 mo after initial ESD.This patient successfully underwent repeat ESD.Metastasis to lymph nodes or distal organs was not observed in any patient.No patients died during the study period.CONCLUSION:ESD appears to be a safe,feasible,and effective procedure for providing accurate histopathological evaluations and curative treatment for eligible foregut NETs.Quan-Lin Li Yi-Qun Zhang Wei-Feng Chen Mei-Dong Xu Yun-Shi Zhong Li-Li Ma Wen-Zheng Qin Jian-Wei Hu Ming-Yan Cai Li-Qing Yao Ping-Hong Zhou 2012World Journal of Gastroenterology2012,18,40:13
18The Homo sapiens Cave hominin site of Mulan Mountain,Jiangzhou District,Chongzuo,Guangxi with emphasis on its age显示文摘One of the most hotly debated and frontal issues in paleoanthropology focuses on the origins of modern humans. Recently, an incomplete hominin mandible with a distinctly weaker mental protuberance than modern human and a great variety of coexisting fossil mammals were unearthed from the Homo sapiens Cave of Mulan Mountain, Chongzuo, Guangxi. The mammalian fauna from the Homo sapiens Cave characterized by the combination of Elephas kiangnanensis, first occurring Elephas maixmus, and Megatapirus augustus, and strikingly different from the Early Pleistocene Gigantopithecus fauna and the Middle Pleistocene Ailuropoda-Stogodon fauna of South China could be regarded as an early representive of the typical Asian elephant fauna. Faunal analysis, biostratigraphic correlation, and, most importantly, U-series dating all consistently support an estimate of ca. 110 ka for the age of the fossil Homo sapiens and coexisting mammalian fauna, that is, the early Late Pleistocene. The fauna is mainly made up of tropical-subtropical elements, but grassland elements have a much greater variety than forest elements, which probably indicates a drier climate at that time. This discovery of early Homo sapiens at the Mulan Mountain will play a significant role in the study of the origin and its environmental background of modern humans.JIN ChangZhu PAN WenShi ZHANG YingQi CAI YanJun XU QinQi TANG ZhiLu WANG Wei WANG Yuan LIU JinYi QIN DaGong R.

19Promotional effect of Si-doped V_2O_5/TiO_2 for selective catalytic reduction of NOx by NH_3显示文摘TiO2 supports doped with different amounts of Si were prepared by a sol-gel method, and 1 wt% vanadia (V2O5) loaded on Si-doped TiO2 was obtained by an impregnation method. The mole ratio of Si/Ti was 0.2, NOx conversion exceeds 94% at 300℃ and GHSV of 41,324 hr-1 , which is about 20% higher than pure V2O5/TiO2 . The catalysts were characterized by XRD, BET, TEM, FT-IR, NH3-TPD, XPS, H2-TPR, Raman and in situ DRIFTS. The results of FT-IR and XPS indicated that Si was doped into the TiO2 lattice successfully and a solid solution was obtained. V2O5 active component could be dispersed well on the support with the increasing of surface area of the catalyst, which was confirmed by Raman and XRD results. Above all, the numbers of acid sites (especially the Br nsted-acid) and oxidation properties were enhanced for Si-doped V2O5/TiO2 catalysts, which improved the deNOx catalytic activity.Yanxiao Pan Wei Zhao Qin Zhong Wei Cai Hongyu Li 2013Journal of Environmental Sciences2013,25,8:13
20Insights into the molecular mechanisms of Polygonum muitiflorum Thunb-induced liver injury: a computational systems toxicology approach显示文摘导致植物的肝损害(HILI ) 的越来越多的案例被报导了,提出新临床的挑战。在这研究,作为一个例子拿蓼 multiflorum Thunb (PmT ) ,我们建议了一条计算系统毒物学途径探索 HILI 的分子的机制。首先, PmT 的化学部件象与自然产品有关的文学一样从 3 个主要 TCM 数据库被提取。然后,已知的目标通过数据集成被收集,并且潜在的复合目标的相互作用(CTI ) 用我们的 substructure-drug-target 被预言基于网络的推理(SDTNBI ) 方法。在由估计 HILI 的症状为 hepatotoxicity 相关的基因屏蔽以后,一个复合目标的相互作用网络被构造。得分功能,也就是 Ascore,被开发在肝估计化学药品的毒性。我们进行了网络分析用分析工具决定 biphasic 效果的可能的机制,包括宾果游戏,小径丰富,机关分发分析和和 CYP450 酶的相互作用的预言。在 PmT 的化学部件之中,有好肠的吸收的 54 个部件被用于分析,并且 2939 CTI 被获得。在在 BioGPS 数据库分析 mRNA 表达式数据以后,与肝疾病有关的 1599 CTI 和 125 个目标被识别。在 15 加重的顶,七与 Ascore 价值 >(emodin,橡黄素, apigenin, resveratrol,法国的酸, kaempferol 和 luteolin ) 3000 显然与 hepatotoxicity 被联系。从小径丰富分析的结果建议在 apoptosis 和新陈代谢之间的多重相互作用可以位于导致 PmT 的肝损害下面。许多在特定的混合物小径被验证了,例如谷胱甘肽新陈代谢,细胞色素 P450 新陈代谢,和 p53 小径,在其它之中。肝炎症状,九胆汁酸的不安和黄或黄褐色的尿也有相应小径,认为我们的方法正当。在结论,这个计算系统毒物学方法揭示可能的有毒的部件并且能对理解 HILI 的机制很有用。这样,方法可能也便于新奇肝毒素的植物的鉴定。Yin-yin WANG Jie LI Zeng-rui WU Bo ZHANG Hong-bin YANG Qin WANG Ying-chun CAI Gui-xia LIU Wei-hua LI Yun TANG 2017Acta Pharmacologica Sinica2017,38,5:12
