Objective To investigate the effects of Danshen Duofensuanyan on the blood coagulation,inflammatory and cardiac function in acute myocardial infarction(AMI) patients who did not accept emergency percutaneous coronary intervention.Methods One hundred and twenty patients,from January 2012 to November 2014 in the First Hospital of Qinhuangdao admission due to acute myocardial infarction frequent episodes of angina(Killip grade Ⅱ,grade m),were randomly divided into two groups:control group (n =60) and observation group (n =60).All patients suffered from severe angina after AMI and heart failure but without PCI.All included patients were gave antiplatelet drug,anticoagulants and Statins,etc.And the patients in observation group were additionally given 7-day Danshen Duofensuanyan injection 200 mg/d once daily intravenously.Platelet aggregation rate (PAG),fibrinogen (FIB),c-reaction protein (CRP),erythrocyte sedimentation rate (ESR),troponin Ⅰ (TNI),plasma brain natriuretic peptide (BNP) and left ventricular end diastolic dimension(LVEDD),left ventricular ejection fraction (LVEF) and cardiac output (CO) of two group were monitored before and after treatment.Results (1)Changes in coagulation,inflammatory cytokines and enzymes between the treatment group and the control group after treatment (Treatment Group:PAG (22.32 ±17.61) %,FIB(3.58±0.74) g/L,CRP(9.34±1.82) mg/L,ESR(10.1±4.6) mm/1 h,TNI(4.51± 1.89) ng/ml);control group:PAG(31.32±21.62)%,FIB(3.84±0.62) g/L,CRP (14.32±1.79) mg/L,ESR(13.2 ± ±5.4) mm/1 h,TNI(5.32±2.31) μg/L) and before treatment(Treatment group:PAG(88.87± 18.21) %,FIB (4.78±0.97) g/L,CRP(32.13±11.59) mg/L,ESR(28.5±6.1) mm/1 h,TNI (56.43 ± 21.87) μg/L);control group:PAG (89.53± 19.35) %,FIB (4.66 ± 0.78) g/L,CRP (29.06± 12.47) mg/L,ESR (29.3 ± 3.2) mm/1 h,TNI (53.69± 18.76) μg/L) were significandy improved,and the differences were statistically significant (P<0.01),and observation group had more significant improvements than the control group(P<0.05 or P <0.01) after treatment.(2) All aboved indexes were improved after treatment except LVEDD.And Danshen Duofensuanyan can significantly improve PAG,FIB,CRP,ESR,TNI,BNP LVEF and CO(P<0.05 or P <0.01).Conclusion Danshen Duofensuanyan can effectively improve the blood rheology and the frequency of angina,and then improve heart functions.

Fas-associated death domain (FADD) is a signal connection protein in Fas/FasL apoptotic path which might play a key role on apoptosis by transferring apoptotic signal. To reveal the intracellular signal transduction molecules involved in the procedure of follicular development in bovine ovary, we cloned FADD gene in bovine ovary tissue with RT-PCR, deleted the termination codon in its cDNA and directionally cloned the amplified FADD gene into eukaryotic expression vector pAcGFP-N1 including AcGFP, successfully constructed the fusion protein recombinant plasmid. After identifying by restrictive enzyme Bgl II/EcoR I and sequencing, transfected pAcGFP-bFADD into CHO-K1 cell mediated by Lipofectamine 2000, observed the expression of AcGFP and detected the transcription and expression of FADD by RT-PCR and Western blotting. The results showed that the cattle FADD was successfully cloned, the pAcGFP-bFADD fusion protein recombinant plasmid was successfully constructed by introducing Bgl II, EcoR I cloning site at two ends of FADD open reading frame and inserting a Kozak sequence before start codon. AcGFP expression was detected as early as 24 h after transfection. The percentage of AcGFP positive cells reached about 65% after 24 h. A 654 bp transcription was amplified by RT-PCR, and 51.4 kD target protein was detected by Western blotting. Construction of pAcGFP-bFADD recombinant plasmid should be helpful for further understanding the mechanism of regulation of FADD on bovine oocytes formation and development.

The intestinal dysbacteriosis is closely associated with the occurrence and progress of radiation-induced intestinal injury. However, the specific mechanism remains unclear. Symbiotic bacteria in the human body play a significant role in maintaining the homeostasis of the intestinal microenvironment while participating in various physiological and pathological processes such as metabolism, immunoregulation, inflammation, and tumorigenesis. Ionizing radiation can destroy the intestinal epithelial barrier, creating an oxidative stress microenvironment. Consequently, the composition and structure of microbiota change, leading to dysbacteriosis through downstream inflammatory factors. Dysbacteriosis can further exacerbate radiation-induced intestinal injury by weakening the resistance of the intestinal epithelial barrier, activating inflammatory signaling pathways, and upregulating radiation-induced apoptosis response. The probiotic supplementation and fecal bacteria transplantation can reduce radiation-induced intestinal injury by regulating the balance of intestinal microbiota. This study reviews the advances in research on the pathogenesis and clinical protection of radiation enteritis based on gut microbiota, in order to provide a theoretical basis and reference for the prevention and treatment of radiation enteritis.

Objective To analyze the necessity of anti-human leukocyte antigen (HLA)antibody monitoring and graft biopsy on early diagnosis of antibody-mediated rejection (AMR). Methods Fifty-one recipients with de novo donor specific antibody (dnDSA)were screened and chosen. Donor specific antibody (DSA)and its ability to bind with C1 q were evaluated. Pathological biopsy of the kidney graft was performed. The recipients diagnosed with AMR were divided into the unstable and stable kidney function groups. Type of DSA,binding ability of the complement and Banff score were statistically compared between two groups. Kaplan-Meier survival analysis of the kidney graft in the recipients from non-rejection, unstable and stable kidney function groups was performed. Results Type of HLA antibody,mean fluorescent intensity (MFI)of DSA,C1 q binding ability and C4d deposition in peritubular capillary did not significantly differ between the unstable and stable groups (all P>0. 05 ). Histomorphologically,the Banff score of microvasculitis,endarteritis,renal tubule-interstitial nephritis,transplantation glomerulopathy and renal tubular atrophy-stroma fibrosis did not significantly differ between two groups (all P>0. 05 ). In the unstable group,the accumulated survival rate of the kidney graft was significantly lower compared with that in the stable group,which was significantly lower than that of their counterparts who were ineligible for pathological diagnosis (P=0. 002). Conclusions It is necessary to perform regular anti-HLA antibody monitoring and pathological puncture examination after renal transplantation,which contributes to early detection and diagnosis of AMR.
