To explore the mechanism of Sijunzi Decoction in the treatment of ulcerative colitis(UC) based on network pharmacology. The active components and corresponding targets of Sijunzi Decoction were extracted with Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and the targets were standardized with the help of Uniprot database. The related targets of UC were obtained through GeneCards database and Disgenet database, and the intersection targets of drugs and diseases were screened by R language. The visual regulation network of "active ingredient-disease target" of Sijunzi Decoction was constructed by Cytoscape software, and the protein-protein interaction network was constructed by STRING database. The functional enrichment analysis of gene ontology(GO) and the enrichment analysis of Kyoto encyclopedia of genes and genomes(KEGG) pathway were carried out on Bioconductor platform, and some of the targets were verified by animal experiments. Through database analysis, a total of 135 active components of Sijunzi Decoction, 114 predicted targets and 80 common targets with UC were obtained. The core target proteins included interleukin 6(IL-6), caspase-3(CASP3), vascular endothelial growth factor A(VEGFA), epidermal growth factor receptor(EGFR) and so on. GO functional enrichment analysis involved 102 items, which mainly affected transcription factor activity, enzyme activity, receptor activity and biochemical process regulation. KEGG pathway enrichment analysis showed that 120 items were involved in human cytomegalovirus infection, cancer, apoptosis, inflammation and other pathways. Mouse experiments showed that Sijunzi Decoction could down-regulate the expression of target proteins IL-6 and caspase-3 and inhibit intestinal epithelial cell apoptosis. The treatment of UC with Sijunzi Decoction is the result of the interaction among multi-components, multi-targets and multi-pathways. It is proved by experiments that Sijunzi Decoction may play an effective role by regulating the expression of IL-6 and caspase-3, and getting involved in apoptosis, inflammation and other pathways.

Objective To compare the efficacy and safety of tacrolimus with those of cyclosporine in treating idiopathic membranous nephropathy (IMN) via network meta-analysis. Methods Databases including PubMed,Embase,CENTRAL (Cochrane),Wanfang Database,CNKI,and VIP citation database were searched for relevant studies according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Package Meta 4.5.0 and Gemtc 0.8.1 in R 3.3.1 were used to analyze the included studies. Results In this network meta-analysis,the complete remission rate (RR=0.98,95% CI:0.70-1.40)and the total remission rate (RR=1.00,95% CI:0.90-1.20)of idiopathic membranous nephropathy did not differ significantly between IMN patients treated with cyclosporine A or tacrolimusand,nor did the incidences of hepatic dysfunction(RR=1.40,95% CI:0.52-4.00),infection(RR=0.75,95% CI:0.18-3.10),or gastrointestinal syndrome(RR=2.1,95% CI:0.36-28.00). Conclusion Cyclosporine A seems to have similar effectiveness and safety to tacrolimus in treating IMN.

The aim of this study was to investigate the pattern of distribution of mating type (MAT) genes of Tuber indicum in ectomycorhizosphere soils from natural T. indicum-producing areas and cultivated truffle orchards and ascocarp samples from different regions. Quantitative real-time PCR and multiplex PCR were used to weight the copy numbers of MAT1-1-1 and MAT1-2-1 in natural truffle soils and cultivated orchard soils. The effect of limestone on the pattern of truffle MAT genes and the correlation between soil properties and the proportion of MAT genes were also assessed. These results indicated that an uneven and nonrandom distribution of MAT genes was common in truffle-producing areas, cultivated truffle orchards, and ascocarps gleba. The competition between the two mating type genes and the expansion of unbalanced distribution was found to be closely related to truffle fructification. Limestone treatments failed to alter the proportion of the two mating type genes in the soil. The content of available phosphorus in soil was significantly correlated with the value of MAT1-1-1/MAT1-2-1 in cultivated and natural ectomycorhizosphere soils. The application of real-time quantitative PCR can provide reference for monitoring the dynamic changes of mating type genes in soil. This study investigates the distributional pattern of T. indicum MAT genes in the ectomycorhizosphere soil and ascocarp gleba from different regions, which may provide a foundation for the cultivation of T. indicum.

ObjectiveDiabetic kidney disease (DKD) has become one of the major causes of end-stage renal disease. Urinary extracellular vesicles (uEVs) contain rich biological information which could be the ideal source for noninvasive biomarkers of DKD. This review discussed the potential early diagnostic and therapeutic values of proteins and microRNAs in uEVs in DKD.

Data SourcesThis review was based articles published in PubMed, Embase, Cochrane, and Google Scholar databases up to November 20, 2017, with the following keywords: "Diabetic kidney disease", "Extracellular vesicle", and "Urine".

Study SelectionRelevant articles were carefully reviewed, with no exclusions applied to the study design and publication type.

ResultsThere is no "gold standard" technology to separate and/or purify uEVs. The uEVs contain a variety of proteins and RNAs and participate in the physiological and pathological processes of the kidney. UEVs, especially urinary exosomes, may be useful biomarkers for early diagnosis and treatment to DKD. Furthermore, the uEVs has been used as a therapeutic target for DKD.

ConclusionProteins and nucleic acids in uEVs represent promising biomarker for the diagnosis and treatment of DKD.

Objective:To study the relationship between apoptosis and the pORF5 protein of Chlamydia trachomatis,and further to explore its molecular mechanisms,which could lay a foundation for chlamydial pathogenic mechanisms.Methods:pGEX-6p/pORF5 recombinant expression vector was transformed to XL1-blue E.Coli to express GST-pORF5 fusion protein,and GST-pORF5 fusion protein was purified with Glutathione Sepharose 4B Beads,and cleaved to get pORF5 protein without GST tag by PreScission protease.The pORF5 protein was used to stimulate HeLa cells at different concentrations,then Western blot was used to evaluate the ex-pression of Bax,Bcl-2 and phosphorylation of PI3K/Akt at different time points,Hoechst staining and Flow cytometry were applied to measure the apoptosis of HeLa cells.Before treated with pORF5 protein for 24 h,HeLa cells were pretreated with PI3K inhibitor LY294002 for 1 h,the expression of Bax,Bcl-2 and the phosphorylation of Akt were evaluated by Western blot,apoptosis rates were also determined.Results:The pORF5 protein changed the expression of Bax and Bcl-2 in dose-and time-dependent manners,pORF5 increased the expression of Bcl-2 and decreased the expression of Bax at the concentration of 10 μg/ml,and there was obvious change at concentration of 15 μg/ml for 24 h.The apoptosis rates of pORF5 treated group were reduced by 27.3% and 8.4% respectively when compared with TNF-α treated group(P<0.01) and untreated group (P<0.05).Akt was phosphorylated after stimulated with pORF5 protein for 15 min,and reached its peak at 30 min.PI3K/Akt inhibitor led to the decrease of the expression of Bcl-2 and phosphorylation of Akt and increase of the expression of Bax,furthermore,PI3K/Akt inhibitor reversed pORF5-mediated anti-apoptosis, the apoptosis rate in LY294002 treated group was increased by 13.0%,when compared with the control group(P<0.01).Conclusion:pORF5 protein could inhibit apoptosis through activating PI3K/Akt signal pathway by induction of Bcl-2 and suppression of Bax.
