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 On basis of physical dose optimization, LQ model was used to investigate the difference between the curves of biological effective dose and physical isodose. The influence of applying the biological dose concept on three dimensional conformal radiotherapy of prostate carcinoma was discussed. Methods Four treatment plannings were designed for physical dose optimization: three fields, four-box fields, five fields and six fields. Target dose uniformity and protection of the critical tissue -rectum were used as the principal standard for designing the treatment planning. Biological effective dose (BED) was calculated by LQ model. The difference between the BED curve drawn in the central layer and the physical isodose curve was studied. The difference between the adjusted physical dose (APD) and the physical dose was also studied. Results Five field planning was the best in target dose uniformity and protection of the critical tissue -rectum. The physical dose was uniform in the target, but the biological effective doses revealed great discrepancy in the biological model. Adjusted physical dose distribution also displayed larger discrepancy than the physical dose unadjusted. Conclusions Intensified Modulated Radiotherapy (IMRT) technique with inversion planning using biological dose concept may be much more advantageous to reach a high tumor control probability and low normal tissue complication probability.

OBJECTIVE To study the carbapenemase genotypes among Acinetobacter calcoaceticus isolates infected after liver transplantation. METHODS The 5.4 software was used to analyze the resistance of Acinetobacter species. Eight strains of imipenem-resistant A. calcoaceticus which were resistant to multiple drugs were collected. Analytical isoelectric focusing electrophoresis was used to measure the pI of the ?-lactamase. The homology of the isolates was determined by pulsed field gel electrophoresis(PFGE). blaTEM, blaSHV, blaIMP, blaVIM, blaOXA Genes for resistant isolates were amplified and sequenced. RESULTS Imipenem-resistant A. calcoaceticus infected after liver transplantation was resistant to multiple drugs. All of 8 strains were produced OXA-23 carbapenemases (pI of 6.7). The results of PFGE indicated there was a trend of resistant clone transmisstion in the transplantation ward. CONCLUSIONS There is a transmisstion of A. calcoaceticus producing OXA-23 carbapenemase in the transplantation ward of our hospital. It is important to monitor powerfully the bacterial resistance to control infection more effectively.

AIM:To observe the characterization in neural cells derived from the hippocampus of embryonic rats and to examine the effect of myelin-associated glycoprotein(MAG) on the proliferation,differentiation and neurite growth of neural stem cells(NSCs).METHODS:The hippocampus cells of embryonic rats were isolated and cultured in vitro.The expressions of nestin and doublecortin,the marks of NSCs,were observed by immunocytochemical method.The rate of proliferating cells was examined by BrdU immunocytochemistry.The average neuronal neurite length and the percentage of differentiated neurons were detected by immunocytochemistry staining.RESULTS:The hippocampus cells of 16 days old embryonic rats had the characteristics of NSCs.The percentage of differentiated neurons(?-tubulin Ⅲ-positive cells) was 18.17%?2.79% and the average neuronal neurite length was(136.27?33.66)?m,seven days after the differentiation initiated in vitro in control group.After NSCs were treated with MAG-Fc(200 ?g/L),the percentage of differentiated neurons and the average neurite length were decreased,respectively,to 10.05%?3.42%(P0.05).CONCLUSION:MAG-Fc inhibits the differentiation and neurite growth of the NSCs,but has no effect on the proliferation.

Objective To observe glucose metabolism in C57 mice treated with different doses of fluoride.Methods Forty male C57 mice (body weight 20-24 g) were divided into four groups which were exposed to 0,50,100 and 150 mg/L sodium fluoride (NaF) by random number table according to body weight,each group had 10 mice.At 2,4,6,8,10 and 12 weeks after fluoride exposure,body weight was measured,blood glucose and glycosylated hemoglobin were detected by blood glucose meter and glycosylated hemoglobin meter,serum insulin and glucagon were detected by enzyme-linked immunosorbent assay (ELISA).Results At 10 and 12 weeks after fluoride exposure,the differences of fasting glucose between groups of C57 mice were statistically significant (F =35.12,21.92,all P ＜ 0.05),the fasting glucose of 100,150 mg/L fluoride groups [(7.7 ± 0.2),(7.3 ± 0.3),(8.6 ± 0.5),(9.1 ± 0.7)mmol/L] were higher than those of the control group [(5.4 ± 0.3),(5.0 ± 0.3)mmol/L,all P ＜ 0.01].The differences of glycosylated hemoglobin,glucagons between groups were statistically significant (F =3.85,8.74,all P ＜ 0.05).The glycosylated hemoglobin of 100,150 mg/L fluoride groups [(7.73 ± 0.76),(7.80 ± 1.15) mmo]/L] were higher than those of the control group [(5.43 ± 1.27) mmol/L,all P ＜ 0.05]; serum glucagon levels of 50,100,150 mg/L fluoride groups [(19.15 ± 11.84),(26.55 ± 15.97),(20.05 ± 7.29)ng/L] were lower than that of the control group [(48.35 ± 2.79)ng/L,all P ＜ 0.01].Conclusion Long term excess fluoride intake can reduce the function of sugar metabolism in C57 mice.

Objective To study the effect of metastasis-associated in colon cancer 1 ( MACC1 ) inhibition by small interference RNA( siRNA) on the formation of tumor cells that promote blood vessels, and to explore its possible molecular mechanism.Methods Synthesized MACC1 specific siRNA was transfected into human lung cancer cell lines XWLC-05. Then, the inhibitory effect of siRNA on the protein level of MET, MEK/p-MEK, ERK/p-ERK, and AKT/p-AKT was detected using Western blotting while the change in VEGF, bFGF and IL-8 protein level was detected using ELISA method. Results Western blotting results indicated that the expression level of MET, p-MEK and p-ERK was significantly decreased in the XWLC-05 cells transfected by MACC1 specific siRNA compared with control and nonsense siRNA groups, but the expression of total protein MEK and ERK did not change.Furthermore, the level of AKT and phosphorylated protein was not affected.ELISA results suggested that the secretion level of VEGF, bFGF and IL-8 was significantly suppressed at 48 h or 72 h compared with control and nonsense siRNA groups.Conclusion MACC1 may reduce the secretion levels of VEGF, bFGF and IL-8 via HGF/c-Met and MEK/ERK signal transduction pathways, and regulate angiogenesis of lung cancer.

Aim To study the interference role of Bcl-2 siRNA on HL-60 cells. Methods Bcl-2 siRNA was synthesized in vitro transcription with silencer siRNA construction kit. The synthesized siRNA was transfected into HL-60 cells with lipid siPORT transfection. Forty-eight hours after the transfection, we used MTT and immunofluorescence to detect cell proliferation and apoptosis,and used RT-PCR and immunofluorescence to detect the level of Bcl-2 mRNA and Bcl-2 protein expression. Result Bcl-2 siRNA reduced the level of Bcl-2 mRNA and Bcl-2 protein expression in HL-60 cells and induced cell apoptosis. There was no difference on the effect of other groups compared with the control. Effective Bcl-2 siRNA specifically degraded Bcl-2 expression in the levels of mRNA and protein and induced HL-60 cells apoptosis.Conclusion These results indicate that siRNA is a highly specific tool for targeted gene knockdown. siRNA-mediated gene silencing is a reliable approach for large-scale screening of gene function and drug target validation.
