The paper is to systematically evaluate the efficacy and safety of Deng Zhan Xi Xin injection ( DZXXI) as an adjuvant treatment for patients with angina pectoris. The Cochrane Library, Medline, EMbase, CBM, CNKI, VIP, and Wan fang Data base were searched. Randomized controlled trials (RCTs) of DZXXI combined with western medicine routine treatment versus western medicine routine treatment alone for angina pectoris patients were all included. All trials were assessed according to the Cochrane Reviewer' s Handbook 5.1 for Systematic Reviews of Intervention and Meta analyses were performed by RevMan 5. 2 Software. A total of 30RCTs (3 086 patients including 1 572 patients of treatment group and 1 514 patients of control group) were included. Meta-analysis of treatment group compared with control group showed superior effect over reducing cardiovascular events ( OR = 0.33; 95% CI: [0.16, 0.67], P = 0.002, improving effective rate of DZXXI as adjuvant treatment for angina pectoris patients (OR = 3.97; 95% CI: [3.15, 5.02]; P < 0.000 010 and electrocardiogram curative effect (OR = 2.21; 95% CI; [1.83, 2.68]; P < 0.000 010. Funnel figure seemed that there was publication bias. The current limited evidence showed that when compared with the control group, treatment group was superior in improving patients with angina pectoris. But based on the limitations of the study, rigorous design with long follow up clinical trials are necessary for further evidence.

Objective To investigate the mechanism of acute inflammatory response and tissue repair when rats accepted transplanted bone marrow mesenchymal stem cells (MSC) in severe acute pancreatitis (SAP).Methods A total of 40 rats were randomly divided into 4 groups which included the normal group (n=10),the model severe acute pancreatitis group (n=10),the transplanted bone marrow mesenchymal stem cells group (n =10),and the combination of bone marrow mesenchymal stem cells and granulocyte colony-stimulating factor (G-CSF) group (n=10).To cure the acute severe pancreatic injury caused by SAP,rats were injected with EDU-labeled MSCs and granulocyte colonystimulating factor (Gr-CSF).The conversion rate of MSCs to pancreatic cells or MSCs to endothelial cells was detected to assess the role of MSCs in tissue regeneration and repair.The expression of amylase,interleukin-6 (IL-6),and interleukin-10 (IL-10) in serum was detected to assess the role of MSCs in an acute inflammatory response.Results The concentrations of amylase and IL-6 were reduced and the concentration of IL-10 was increased in MSC and MSC+G-CSF groups after the onset of SAP.Flow cytometry showed a small amount of MSCs converting to endothelial or pancreatic cells,but the conversion rate was relatively low.Conclusions MSCs can play an important role in the antipre-release of inflammatory mediators,reducing acute immune response to control the acute inflammatory response in SAP.Moreover,MSCs can repair a damaged pancreas by converting into both pancreatic and endothelial cells.

ObjectiveTo explore the mental health level of family members of stroke patient and related factors.Methods34 stroke patients' family members were tested with the Symptom Checklist-90(SCL-90), and compared with norms; SCL-90 factor scores, which were higher than that of norms, were analyzed for related factors.ResultsScores of 4 factors in the SCL-90 (somatization, depression, anxiety and phobia) were higher than norms in the family members of stroke patients. Scores of somatization factor correlated with the education background; depression factor correlated with the family income variable; anxiety factor correlated with the cognitive impairment variable of patients. In the correlation analysis with patient's activities of daily living (ADL) scores, somatization factor negatively correlated with total score of ADL and hygiene, feeding, bowel management, locomotion, bathing scores; both depression factor scores and positive item numbers negatively correlated with feeding and bowel management scores; phobia anxiety factor scores with hygiene, feeding, bowel management, communication, locomotion, bathing and total scores.ConclusionThe mental health level of family members of stroke patient is lower, and it is related to family income reduction, patient's cognitive impairment, and especially with the patient\s ADL level.

Halohydrin dehalogenase is of great significance for biodegradation of the chlorinated pollutants, and also serves as an important biocatalyst in the synthesis of chiral pharmaceutical intermediates. A putative halohydrin dehalogenase (HheTM) gene from Tistrella mobilis KA081020-065 was cloned and over-expressed in Escherichia coli BL21 (DE3). The recombinant enzyme was purified by Ni-NTA column and characterized. Gel filtration and SDS-PAGE analysis showed that the native form of HheTM was a tetramer. It exhibited the highest activity at 50 degrees C. The nature and pH of the buffer had a great effect on its activity. The enzyme maintained high stability under the alkaline conditions and below 30 degrees C. HheTM catalyzed the transformation of ethyl(S)-4-chloro-3-hydroxybutyrate in the presence of cyanide, to give ethyl (R)-4-cyano-3-hydroxybutyrate, a key intermediate for the synthesis of atorvastatin.

Objective To determine the distribution of HCV genotypes in patients with chronic hepatitis C,study the distribution of genotype in different gender and the relationship between genotypes and serum HCV-RNA levels.Methods Two hundred and six cases of HCV RNA positive patients(all with relevant clinical data) receiving pegylated interferon therapy were collected from May to December 2010.HCV RNA was detected in 206 hepatitis C patients from 40 hospitals in China by Roche Cobas AmpliPrep/Cobas TaqMan HBV test,and genotype was determined by Abbott RealTime HCV G enotype Ⅱ .The distribution of genotypes in the gender was analyzed by chi-square test analysis.The relationship between genotypes and serum HCV RNA levels was detected by single factor analysis and two independent sample t test analysis.Results There were seven different subtypes of HCV in 206 samples,including genotype 1,7 cases(3.4% ,7/206); genotype 1a,2 cases(1.0%,2/206); genotype 1b,123 cases (59.7 %,123/206); genotype 2,32 cases(15.5 %,32/206); genotype 3,27 cases(13.1%,27/206); genotype 6,6 cases(2.9% ,6/206) ;genotype 1/6,5 cases(2.4% ,5/206) ;genotype 2/4,1 cases(0.5%,1/206).There was no significant difference between HCV genotype and gender in 132 cases with genotype 1 and 65 cases with non-genotype 1(genotype 2,3,6) (x2 = 0.000,P ＞ 0.05).There was significant association between quantity of HCV RNA and genotype in 188 patients with HCV(F = 3.371,P＜ 0.01).The 197 patients with HCV single genotype were divided into five groups in terms of region(East,South,West,North and Center).There was no significant difference between HCV genotype 1 and non-genotype 1 in the five groups(x2 = 5.840,P ＞ 0.05).Conclusions It is suggested that HCV 1 b is the most prevalent type in China,followed by HCV 2.There is no significant difference between HCV genotype and gender.The levels of HCV RNA with genotype 1b are significantly higher than those with genotype 3.The levels of HCV RNA with genotype 2 are significantly higher than those with genotype 3.The levels of HCV RNA with genotype 6 are significantly higher than those with genotype 3.

This study is to explore characteristic indexes in evaluation criteria for rat skin anaphylactoid test comparing skin blue spot OD values at the treated position and the control position in the same animal. Common contrast agents, traditional Chinese medicine injections and injections' active pharmaceutical ingredients or excipients in the existing clinical anaphylactoid reaction reports were taken as test drugs in the rat skin anaphylactoid test to define the K value: K > 2 represents positive anaphylactoid reaction, 1.2 ≤ K ≤ 2 represent doubtable anaphylactoid; K < 1.2 represents negative anaphylactoid reaction, which were taken as the criteria for evaluating anaphylactoid of tested drugs. The evaluation result and that for classic criteria were compared to study the applicability of K value. According to the comparison, K value, as the evaluation criteria in the rat skin anaphylactoid test, can more truly reflect the actual situation of skin aizen and minimize the error caused by animal individual factors. Compared with positive and negative two-level criteria for blue spot diameter, K value's positive, doubtable and negative three-level criteria are more objective and accurate. Therefore, K value can be used as the evaluation criteria in the rat skin anaphylactoid test.
