Background:Tuberculosis (TB) is one of the most debilitating diseases worldwide.Current studies have shown that vitamin D plays a significant role in host immune defense against Mycobacterium tuberculosis,but clinical trials reported inconsistent results.Therefore,we systematically reviewed the literature to investigate whether vitamin D supplementation could improve the effect of anti-TB therapy.Methods:We systematically searched PubMed,Embase,and the Cochrane Central Register of Controlled Trials from their inception to February 8th,2019 for randomized controlled trials on vitamin D supplementation in patients with pulmonary TB receiving anti-TB therapy.The primary outcomes were time to sputum culture and smear conversion and proportion of participants with negative sputum culture.The secondary outcomes were clinical response to treatment and adverse events.A random-effects model was used to pool studies.Data were analyzed using RevMan 5.3 software.Results:Five studies with a total of 1126 participants were included in our meta-analysis.Vitamin D supplementation did not shorten the time to sputum culture and smear conversion (hazard ratio [HR] 1.04,95% confidence interval [CI] 0.89-1.23,P =0.60;HR 1.15,95% CI 0.93-1.41,P =0.20,respectively) and did not lead to an increase in the proportion of participants with negative sputum culture (relative risk [RR] 1.04,95% CI 0.97-1.11,P =0.32).However,it reduced the time to sputum culture conversion in the sub-group of participants with TaqI tt genotype (HR 8.09,95 % CI 1.39-47.09,P =0.02) and improved the multidrug-resistant (MDR) TB sputum culture conversion rate (RR 2.40,95 % CI 1.11-5.18,P =0.03).There was no influence on secondary outcomes.Conclusions:Vitamin D supplementation had no beneficial effect on anti-TB treatment,but it reduced the time to sputum culture conversion in participants with tt genotype of the TaqI vitamin D receptor gene polymorphism and improved the MDR TB sputum culture conversion rate.

Thrombus is a major factor leading to cardiovascular diseases such as myocardial infarction and stroke. Although fibrinolytic anti-thrombotic drugs have been widely used in clinical practice, they are still limited by narrow therapeutic windows, short half-lives, susceptibility to inactivation, and abnormal bleeding caused by non-targeting. Therefore, it is crucial to effectively deliver thrombolytic agents to the site of thrombus with minimal adverse effects. Based on the long blood circulation and excellent drug-loading properties of human serum albumin (HSA), we employed genetic engineering techniques to insert a functional peptide (P-selectin binding peptide, PBP) which can target the thrombus site to the

Objective To detect brain natriuretic peptide(BNPs) level in serum in order to confirm its applical value.Methods Forty-eight patients with congestive heart failure(CHF) were chosen,which included 36 patients with pneumonia,12 patients with congenital heart diseases.Forty heathy children were chosen as control group.BNPs level of two groups were detected by enzyme label.Results The level of BNP in patients with CHF(that′s positive group) was obviously higher than that in control group in the stage of CHF and recoverty(t=14.30,20.38 all P0.05),this included that the cardiac function had significantly changes in the stage of CHF,at the same time,the level of BNP had negative correlation to CI and LVEF(r=-0.61,-0.79 all P

0.05)and the TNM staging (P=0.55).A mild elevated compared other pathological classification was found in small cell lung cancer (0.191?0.275).Conclusions The results showed that RFQ-PCR was suitable for measurement of the mRNA level of PLKI in bronchoscopic bioptic specimens.This study suggest elevated expression of PLK1 might play a important role in development of lung cancer,so that PLK1 might be a potential tumor marker for Lung cancers.Advanced studies will be needed to clarify that PLKI mRNA level do not relate to TNM staging and pathological classification.

Objective To study the structure of class 1 integrons in 90 strains of Pseudomonas aeruginosa isolated during two periods of 1992-1996 and 2003-2005,and to get information about the structure changing of class 1 integrons by comparing their structures in two different periods.Methods Routine PCR and long PCR were performed to amplify the class 1 integrons and the gene cassettes they carried, followed with sequencing and blast via GenBank.Results Thirteen out of 41 strians ioslated during the period of 1992-1996 were positive on class 1 intergrons.Long PCR showed that the class 1 integron was 1868 bp in length and contained 2 resistance genes averagely.Six types of resistance genes of qacEA1 (n=6), sull (n=14),aadA1 (n=2),aadB (n=1),PSE-1 (n=2) and tetA (n=1) were found in these integrons, which consisted of 5 patterns of resistance cassette arrangements.Nineteen strains were proved to carry class 1 integrons in 49 isolates from 2003-2005.The mean DNA sequence length of them was 3383 bp with 3.6 resistant genes in averagely,10 types of resistance genes,qacEA1 (n=18),sull (n=25),aadA1 (n=6), aadB (n=7),aacA4 (n=2),PSE-1 (n=3),VEB-1 (n=4),OXA10 (n=1),cm1 A (n=1) and tetA (n =2),were identified in these integrons,which were composed of 9 patterns of resistance cassette arrangements.Conclusion In terms of produce length and resistance cassettes carried in the integrons, greater complexity is found in the structure of class 1 integrons in strains isolated during 2003-2005 than those during 1992-1996.
