Objective To study the influence of valsartan combined with indapamide on the UmAlb level and blood pressure in patients with hypertension and diabetes mellitus.Methods 90 patients with hypertension and diabetes mellitus were selected and randomly divided into three groups by number table.30 cases of the control group A were treated with indapamide,30 cases of the control group B were treated with valsartan,30 cases of the observa-tion group were treated with indapamide combined with valsartan.After treatment,the clinical parameters and effect of the three groups were compared.Results After treatment,the systolic blood pressure and diastolic blood pressure of the three groups were decreased(all P <0.05),and the observation group decreased obviously(all P <0.05).The total effective rate of the observation group was 96.7%,which was higher than 86.6% of the control group A and 83.3% of the control group B(χ2 =4.1 2,4.22,all P <0.05).Conclusion In the treatment of hypertension and diabetes,the antihypertensive effect of indapamide combined with valsartan is obvious and can protect the renal func-tion,which should be promoted in clinical use.

Objective　To evaluate the efficiency of low molecular weight heparin(LMWH, fraxiparine) given as a single predialysis bolus injection with reused dialyzers in comparison with standard heparin(SH) administered with a continuous infusion. Methods　30 hemodialysis patients were studied in a radomized crossover fashion. Dialyzers fibrer bundle volumes(FBV), predialysis hemocrit and 2 h clearance of urea, creatinine were observed in the first, the fourth dialysis. The plasma heparin activities(anti-Fxa levels) were measured by the chromogenic substrate assay in 0 h, 2 h, 4 h of dialysis. Results　Significant increase (P<0.05) was seen in the number of dialyzer reuse in LMWH group compared with SH group; there was not significant decrease in dialysis FBV as well as 2 h clearance of urea, creatinine (P>0.05); in addition, the plasma heparin activity(anti-Fxa levels) were comparable in both groups after 2 h of dialysis, however, they were significantly higher after 4 h in the LMWH than those in the SH group (P<0.05). Conclusion　LMWH as a single bolus dose can prevent decrease in dialyzer clearance. It is clinically worthy of further popularity.

Objective:To investigate the effects of Mycobacterium Phlei on functional states of Th_1/Th_2 in patients with chronic obstructive pulmonary disease(COPD),and clinical effects on the prevention of acute exacerbation of chronic obstructive pulmonary diseases(AECOPD).Method:60 patients with COPD of gradeⅡwere randomly divided into a treatment group and controlled group.The controlled group were given a routine therapy,while the treatment group were given utilins in addition to the routine treatment.The contents of?-interferon(IFN-?) and interleukin-4(IL-4) in their peripheral blood and their clinical efficacy were observed before and after the treatment.Result:Before and after the treatment, IFN-?/IL-4 ratio in the treatment group was 1.39?0.20 and 1.94?0.31 respectively(P

Objective To explore the clinical efficacy of NEOVEIL in postoperative pulmonary air leakage of pulmonary bullae resection by video-assisted thoracic surgery. Methods We retrospectively analyzed clinical data of 37 cases received NEOVEIL combined with ATB45 in video-assisted thoracic surgery (the NEOVEIL group), and clinical data of 40 cases by ATB45 alone(the control group) . We compared postoperative hospitalization time, keeping time of pleural cavity tubes, the pulmonary leakage time and the incidence of pulmonary infection in the two groups. Results There was no postoperative mechanical ventilation,hemothorax and death. In the NEOVEIL group, the postoperative hospitalization time was 5 to 9 days, the postoperative keeping time of pleural cavity tubes 2 to 4 days, the postoperative pulmonary leakage time 0 to 2 days with 4 patients un-leakage, and 1 patients with pulmonary infection; whereas the postoperative hospitalization time was 6 to 10 days,the postoperative keeping time of pleural cavity tubes 3 to 6 days,the postoperative pulmonary leakage time 2 to 5 days and 8 patients with pulmonary infection in the control group. There was statistical significance in the postoperative hospitalization time, keeping time of pleural cavity tubes, the pulmonary leakage time and the incidence of pulmonary inflammation in two groups(P ＜ 0. 05). The incidence of pulmonary inflammation of the NEOVEIL group (2. 7%) was significantly lower than that of the control group(20. 0%)(x2 = 4. 02, P ＜ 0. 05). Conclusion The operative effectiveness of the NEOVEIL group is better than that of the control group. The NEOVEIL can prevent the postoperative pulmonary leakage.

Objective To construct a recombinant interfering RNA(miRNA)plasmid vector targeting annexinA3 and observe its impact on the growth and apoptosis of human gallbladder cancer cell line SGC-996.Methods Four small fragments of miRNA and one negative control were sequenced and cloned into vector pcDNATM 6.2-GW/EmGFPmiR.The recombinant plasmids were then transfected into gallbladder cancer cell line SGC-996 by positive liposomal transfection.The transcription and translation level of annexinA3 expression were detected by RT-PCR and Western Blot.Meanwhile, the proliferation and apoptosis of transfected tumor cells were determined by MTT and flow cytometry.Results The recombinant plasmids containing annexinA3 miRNA were successfully constructed.AnnexinA3 expression was significantly knocked down after miRNA plasmid transfection.Transfection of annexinA3 gene miRNA could effectively inhibit the proliferation of gallbladder cancer cell and promote apoptosis.Conclusion AnnexinA3 gene silenced by miRNA can induce the apoptosis of human gallbladder cancer cell line SGC-996.The process might serve as a potential approach for cancer gene therapy.

Objective To investigate the change and clinical significance of serum procalcitonin (PCT) level in patients with community-acquired pneumonia (CAP).Methods One hundred and forty-five CAP patients were enrolled.Serum PCT level was measured by immunofluorescent antibody staining method.CURB-65 score and pneumonia severity index (PSI) score were used to evaluate the severity of the patients with CAP.Correlations between PCT and blood white blood cell (WBC) count,serum C-reactive protein (CRP),PSI score,CURB-65 score,hospitalization duration and mortality were analyzed with Pearson correlation analysis,Logistic regression analysis and so on.Results Serum PCT in patients with CAP showed positively correlated with CURB-65 score and PSI score (r =0.606,0.943,P＜ 0.01 ),and serum PCT was also positively correlated with age,serum CRP and hospitalization duration (r =0.753,0.233,0.281,P ＜0.01),but it wasn't correlated with blood WBC count (r =0.152,P ＞0.05).Logistic regression analysis showed that each increment of 1 μ g/L for serum PCT would increase 2.828-fold for the risk of death in CAP patients.Conclusions Serum PCT predicts the sensitivity and specificity of CAP with a similar prognostic accuracy with CURB-65 score and PSI score.Serum PCT in patients with CAP correlates with hospitalization duration and mortality.Therefore,it is a promising prognostic marker to evaluate the severity and outcome of CAP.It may serve as a useful marker for clinicians to evaluate the severity and prognosis of CAP.

Aim Drug repositioning is to find new indications for existing drugs,however,potential drug-disease relationships are often hidden in millions of unknown relationship.With the analyzing of medical big data,we predict the potential drug-dis-ease relationships.Methods Based on the assumption that similar drugs tend to have similar indications,we applied a rec-ommendation-based strategy to drug repositioning.First,we col-lected the information of known drug-disease therapeutic effect, side effect,drug characters and disease characters;second,we calculated the drug-drug similarity measurements and disease-disease similarity measurements;last,we used a collaborative filtering (CF)method to predict unknown drug-disease relation-ships based on the known drug-disease relationships by integra-ting the similarity measurements,and built a ranking list of pre-diction results.Results The experiments demonstrated that a-mong the TOP 500 of the list,1 2.8% were supported by clinical experiments or review,and 20% were supported by model or-ganism or cell experiments.Conclusion Compared to the clas-sification model and random sampling results,the CF model can effectively reduce the false positives.
