Objective:To analyze the effect of simvastatin combined with tanshinone in the treatment of patients with acute cere-bral infarction. Methods:The patients with acute cerebral infarction were randomly divided into the treatment group (n=50) and the control group (n=50). The control group was given tanshinone treatment, the treatment group was given simvastatin treatment addi-tionally, and the treatment course was 14 d. The NIHSS ( nerve function defect degree) , ADL ( daily life activity) and the treatment effect before and after the treatment were comprehensively evaluated and compared between the two groups. Results: Compared with those before the treatment, the NIHSS and ADL scores were significantly improved in the two groups after the treatment, and the differ-ences were statistically significant (P<0. 05), and the improvement in the treatment group was significantly better than that in the control group with statistical significance (P<0. 05). The total effective rate of the observation group was 98%, which was higher than that (70%) in the control group (P<0. 05). Conclusion: Simvastatin combined with tanshinone in the treatment of acute cerebral infarction shows obvious therapeutic effect, which can obviously improve neurologic deficits and daily life activity, and is worthy of fur-ther clinical application.

Objective To observe the influence of wind-dispelling therapy on therapeutic effect of blood-cooling and kidney-tonifying herbs for chronic idiopathic thrombocytopenic purpura(CITP),and to investigate its immunoregulatory effect.Methods Forty-two CITP patients were randomized into 2 groups:the treatment group(N=22) received therapy of dispelling wind,cooling blood and tonifying kidney,and the control group(N=20) received therapy of cooling blood and tonifying kidney.Six weeks constituted one treatment course,and the treatment lasted 3 courses.Serum interleukin 2(IL-2),soluble IL-2 receptor(sIL-2R),Fas protein,Fas-L protein,and platelet-associated immunoglobulin G(PAIgG) levels and lymphocyte subtypes were compared before and after treatment.Results In the treatment group,14 patients were clinically cured,5 markedly effective,2 effective,1 ineffective and the total effective rate was 95.5%;in the control group,8 patients were clinically cured,4 markedly effective,3 effective,5 ineffective and the total effective rate was 75.0%.The therapeutic effect in the treatment group was superior to that in the control group(P

OBJECTIVE:To investigate the influence of cephalosporins antibiotics on cost and length of hospital stay in pa-tients underwent gallbladder calculus resection,and to provide reference for drug use in clinic. METHODS:A total of 1866 patients underwent gallbladder calculus resection were collected from 9 third grade class A hospitals in Guangxi during 2013-2014. SPSS 22.0 software was adopted to analyze cost and length of hospital stay in patients underwent gallbladder calculus resection. RESULTS:Multi-factor analysis showed that the factors which significantly affected the cost and length of hospital stay were antibiotics,hospi-tals,age,surgery types and disease species (all P<0.01). The antibiotics were divided into the subset 1-4 according to the cost of hospital stay:the subset 1 only contained cefuroxime(9454 yuan);the subset 2 contained noncephalosporins(16199 yuan)and ce-fazolin pentahydrate(17241 yuan);the subset 3 contained ceftazidime(20716 yuan),other cephalosporins(21046 yuan)and cefo-taxime sulbactam(22724 yuan);subset 4 contained cefotaxime sulbactam(22724 yuan),cefoperazone sulbactam(23688 yuan), cefoxitin(24685 yuan)and cefodizime(24698 yuan). The antibiotics were also divided into the subset 1-4 according to the length of hospital stay:the subset 1 only contained noncephalosporins (7.61 d);the subset 2 contained cefuroxime (8.94 d) and cefazolin pentahydrate(9.78 d);the subset 3 contained cefoxitin(13.39 d),cefodizime(13.44 d),other cephalosporins(14.32 d)and ceftazi-dime(14.60 d);the subset 4 included cefoperazone sulbactam(16.03 d)and cefotaxime sulbactam(16.91 d). The higher the subset numbers,the higher the cost of hospital stay or the longer the length of hospital stay;there were statistical differences among differ-ent subsets (P<0.05),while there was no statistical difference among the same subsets (P>0.05). CONCLUSIONS:Cephalospo-rins antibiotics can significantly influence the cost and length of hospital stay in patients underwent gallbladder calculus resec-tion. Antibiotics selection canbe considered comprehensively ac-cording to local medical resources and the patients'demands.

[Objective] To explore the effect of wind-expelling and blood-cooling therapy in treating chronic idiopathic thrombocytopenia purpura (ITP) . [Methods] Thirteen cases of chronic ITP differentiated in TCM as heat-induced blood extravasation (group A) were treated with wind-expelling and blood-cooling therapy. The changes of peripheral T-lymphocyte subsets and natural killer (NK) cells before and after treatment were observed and compared with the normal volunteers (group B). [Results] Before treatment, peripheral T-lymphocyte subsets of CD3 and CD4 levels, CD4/CD8 ratio and NK cells count were lower in group A than those in group B while CD8 level was higher ( P

This study was aimed to optimize the extraction process of hyperoside from leaves ofAcanthopanax senticosusby compounding-enzyme method and orthogonal experiment. The hyperoside compound was regarded as standard and determined by HPLC. Based on the experiments of 4 factors including the enzyme amount, temperature, extraction time and PH values, the extraction process of hyperoside was determined by the orthogonal experiments and variance analysis. The results of single-factor experiments showed that different enzymes showed different effects on the enhance yield of hyperoside. The effects of different factors showed that the order of PH, neutral protease, temperature, time, pectinase, xylanase and cellulose was from strong to weak. Through orthogonal analysis, the optimum conditions were 2% pectinase, 2% xylanase, 0.5% neutral protease, and 0.5% cellulose, under the temperature of 30°C, extraction time of 10 min, and pH = 4.5. Under these conditions, the extraction rate was 1.84%. The yield was increased 107% compared with traditional process. It was concluded that the use of compounding enzyme can increase the yield of hyperoside, which possessed a lot of economic benefits.

Objective To investigate the influence of diabetes mellitus (DM) on left ventricular(LV) remodeling in patients with acute ST-segment elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (PCI) within 12 hours of symptom onset. Methods Four hundred and fifty-one consecutive patients with acute STEMI treated by primary PCI were prospectively enrolled in the current study. Baseline, angiographic and PCI features and prevalence of LV remodeling at one-week during hospitalization and 6-month clinical follow-up by two-dimensional echocardiography were compared between 93 diabetic and 358 non-diabetic patients. Results Despite similar baseline clinical and angiographic characteristics, symptom-to-door time was longer (399±106 min vs. 321±116 min, P=0.006) and prevalence of multivessel disease was higher (65.6%vs. 51.7%, P=0.02) in diabetic patients. More patients in diabetic group had LV remodeling at 6-month clinical follow-up (29.0%vs. 17.3%, P=0.01), and DM was an independent predictor of LV remodeling (RR 2.1, 95%CI 1.31-4.79, P=0.02). The rate of rehospitalization due to heart failure did not differ between diabetic and non-diabetic patients (12.9%vs. 8.1%, P=0.15), however, more adverse events occurred in patients with LV remodeling comparing to those without LV remodeling (25.8% vs. 6.6%, P < 0.001). Conclusions Diabetic patients with STEMI often have an increased risk of LV remodeling after treated by primary PCI. Thus, comprehensive therapeutic strategy for diabetic patients presented with STEMI is required considering the poor prognosis of these patients with LV remodeling.

Objective To set up a new method,which is sensitive,low cost,rapid and suitable for clinical application for FTO gene rs9930506 variant genotyping basing on high resolution melting (HRM) platform,and to preliminarily put into practice in susceptibility analysis for metabolic syndrome (MS) in Beijing.Methods Unlabelled probe with C3-spacer block specific for rs9930506 variant has been designed according to the Refseq from GenBank.With LC-Green plus dye pre-mixed,we scanned the signal for the genotype analysis after PCR amplification and HRM reaction.Restriction fragment length polymorphism (RFLP) and PCR-sequencing methods were designed as 2 control genotyping methods for the evaluation of accuracy and convenience.Afterwards,the HRM-based method was put into practice in metabolic syndrome patients (n =500) and control groups (n =500) for rs9930506 genotyping,and primarily study the association between rs9930506 and MS.Results All the 3 methods could genotype rs9930506 appropriately,although the 2 control methods seemed to be a little time-inefficient.The call rate of HRM-method was 100％ and sampling accuracy reached 99.3％ according to sequencing results.In the MS group,AA,AG and GG genotypes were found in 290,185 and 25 cases,respectively.And in the control group,those were found in 344,138 and 18 cases.No genotype distribution difference was detected between control group and HapMap-CHB data (P =0.520 ).The genotype distributions were all in Hardy-Weinberg equilibrium in each group.AA genotype of rs9930506 seemed to reduce the risk for MS( OR =0.626,95％CI =0.483-0.812).Conclusions The AA genotype of rs9930506 variant in FTO might be a protective factor for MS in Beijing population.The susceptibility related genotyping in clinical samples could be more rapid,precise and inexpensive with the development of HRM in genotyping.
