Objective To evaluate the applicability of small molecular markers of nephrotoxicity that in prediction of drug toxicity.Method Extracts of five kinds of traditional Chinese medicines (Tripterygium wilfordii,Strychni semen,Aristolochiafangchi,Rhei Radix et Rhizoma,and Xanthium sibiricum) that had known as nephrotoxicity were ig given to rats to establish renal injury models,and the blood samples were collected after administration for 1 and 7 d.Then blood samples were analyzed by UPLC/Q-TOF-MS for five kinds of small molecule biomarkers-thymidine,lyso-phosphatidylcholine (LPC 16:1),LPC (18:4),LPC (20:5),and LPC (22:5).The support vector machine (SVM) prediction model was established to determine the toxicity.The levels of Cr and BUN in serum were determined by automatic biochemical analyzer.The rats in each group were sacrificed after blood collection,and the kidneys were taken for HE staining.Result No toxicity was observed in the control group,and the biochemical test results showed no renal injury after mentioned five kinds Chinese herbs were given for 1 d,while SVM model of nephrotoxicity had been found abnormal.After administration for 7 d,the results of SVM model show renal toxicity,which were consistent with biochemical and pathological examination.Conclusion Metabonomics combined with the earlier established SVM model enabled prediction of drug nephrotoxicity more sensitively,quickly and \ccurately,and it is of great significance for the discovery of drug toxicity as well as the prevention and treatment of drug-induced renal injuries in clinic.

ObjectiveTo analyze the clinical manifestation of hemolytic disease of the newborn (HDN) due to anti-M and Rhesus system.MethodsClinical information was collected and analyzed for three cases with HDN due to anti-M and 64 with Rhesus hemolytic disease, who were admitted to Department of Neonatology, Beijing Children's Hospital Affiliated to Capital Medical University from February 2011 to January 2015, as well as another 28 cases of HDN due to anti-M with complete information retrieved from literature in Wanfang and China National Knowledge lnfrastructure (CNKI) Database from 1992 to 2014.Chi-square test was performed for statistical analysis.ResultsTwo out of the 64 Rh hemolytic babies gave up therapy due to kernicterus and another two out of the 31 MN hemolytic babies, obtained from literature, died 24 h after birth because of anemia or edema, while the rest survived. Although more babies were the first child of the family in HDN due to anti-M than those of Rh hemolytic disease [26%(8/31) vs 9%(6/64),χ2=4.487, P=0.034], but lower incidence of jaundice [81%(25/31) vs 98%(63/64),χ2=9.686,P=0.002], less proportion of presentation of jaundice within 24 h after birth [29% (9/31) vs 64%(41/64),χ2=10.279,P=0.001] and lower positive rate of direct antiglobulin test [39%(12/31) vs 100%(64/64), Fisher exact test,P=0.000] were shown in HDN due to anti-M. No significant difference was found in the incidences of hyperbilirubinemia [58%(18/31) vs 66%(42/64),χ2=0.513], severe hyperbilirubinemia [23%(7/31) vs 36%(23/64),χ2=1.724], anemia [81%(25/31) vs 89%(57/64),χ2=1.253] and severe anemia [29%(9/31) vs 34%(22/64),χ2=0.271] between HDN due to anti-M and Rh hemolytic babies (allP>0.05).ConclusionsHDN due to anti-M and Rhesus hemolytic disease can cause severe pathological jaundice and/or anemia in newborns. Indirect antiglobulin test should be offered when direct antiglobulin test is negative which is helpful in the diagnosis of HDN due to anti-M.

Objective:Scope review of exercise-related research in patients with inflammatory bowel disease (IBD), while pointing out the limitations of existing research, and providing references for future studies in this area.Methods:We searched PubMed, EMBASE, Web of science, Cochrane databases, China Biology Medicine, Chinese National Knowledge Infrastructure, Wan Fang Data, and Chinese Science Journal Database for studies related to exercise intervention in patients with IBD from January 1974 to July 2020. We extracted data from the included studies. Then we summarized and presented the results.Results:16 articles were finally included, of which 14 were randomized controlled trials and 2 were quasi-experimental studies. Results show that exercise methods can be divided into four categories: aerobic exercise, resistance exercise, flexibility exercise and mixed exercise. The intensity of exercise was mostly low to moderate. The frequency of exercise was mostly 3 times/week, lasting for 30-60 minutes per session. The results showed that exercise had positive effects on physical fitness, bone density, anxiety and depression, quality of life among patients with IBD. However, the effect of exercise on disease activity are diverse.Conclusion:exercise is beneficial to the mental and physical health among this group, but the existing studies have small sample sizes, short exercise intervention period, neglect of individualization in exercise prescription design, low exercise compliance, non-uniformity of exercise effect evaluation indicators.

Objective To identify molecular typing of Brucella abortus isolates in Xinjiang,and determine the identification ability of multiple locus variable-number tandem repeat analysis (MLVA).Methods The optimized Brucella AMOS-PCR was used for identification of Brucella (n =7) genus and species in Xinjiang from 2010-2015,and MLVA-16 was used to further identify the isolates.Results were compared with the data of the Brucella standard strain provided by the http://mlva.u-psud.fr database.Cluster analysis was carried out with Bionumerics 6.6.Results The results of AMOS-PCR and MLVA-16 were identical,all were Brucella abortus.Further classification results of the MLVA-16 showed that the strain in Xinjiang was type 3 of Brucella abortus,which was basically the same as that of the domestic Brucella.Conclusions The molecular typing of isolates separated in Xinjiang is type 3 of Brucella abortus.MLVA can identify Brucella at the level of species,and highly sensitive to Brucella biotype and isolates differences,which provides a basis for the traceability and evolution of brucellosis epidemic strains.

Circular RNA(circRNA) is a class of endogenous non-coding RNA molecules,which is ubiquitous in eukaryotic cells.They have a closed ring structure,and are mainly composed of exons and / or introns.Circular RNAs have been widely studied in recent years,and studies show that they are remarkably stable,highly conserved and cell-or tissue-specifically expressed.Recently,it has been found that circRNAs can regulate gene expression at the transcriptional or post-transcriptional level by interacting with microRNAs and other molecules.Recent studies have shown that circular RNA may be associated with various diseases,including atherosclerotic vascular disease,prion diseases,neurological disorders,osteoarthritis and diabetes mellitus.In addition,circular RNAs exhibit abnormal expression in a variety of types of cancers,including colorectal cancer,hepatocellular carcinoma,and gastric cancer.Therefore,we believe that circular RNA can be used as a diagnostic marker or therapeutic target of clinical diseases.This article reviews the potential of circular RNA as a diagnostic marker and therapeutic target.
