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 discuss the quantitative diagnosis of stagnation of Qi and blood stasis syndrome in chronic prostatitis. To make diagnosis chart and ensure diagnosis threshold level which provide statistics evidence for syndrome differentiation of TCM. Methods By the statistical ways, 168 cases of chronic prostatitis belong to stagnation of Qi blood and stasis syndrome and 198 cases of non-stagnation of Qi and blood stasis syndrome were investigated. To make a diagnosis chart and ensure diagnosis threshold level by applying the method of the maximum likelihood discriminatory analysis. Results The quantitative diagnosis chart was made and diagnosis threshold level was 26. According to the retrospective and prospective test, its sensitivity, especially degree, coincidence rate, error rate and positive likelihood ratio were 94.64%, 88.89%, 91.53%, 8.47%, 8.52 and 94.28%, 90.32%, 92.42%, 7.58%, 9.74. Conclusion The indexes of the quantitative diagnosis have good objectivity. According to the retrospective and prospective test, the diagnosis chart was proved to be practical.

OBJECTIVE To investigate the characteristics and antibiotics resistance of nosocomial infection caused by Stenotrophomonas maltophilia after open-heart operation.METHODS The clinical data of 324 patients with microbiologically documented nosocomial infection from Jan 2004 to Dec 2006 were retrospectively analyzed.RESULTS There were 34 infected cases caused by S.maltophilia,and accounted for 10.5% of all infections during the same period.All infected patients had serious original heart diseases,and received previous glucocorticoids and broad-spectrum antibiotic therapy.Thirty patients prolonged mechanical ventilation time for over 2 weeks.Results of susceptibility test showed that trimethoprim-sulfamethoxazole,ticarcillin-clavulanic acid and levofloxacin were the most active antibiotics,followed by ceftazidime and ciprofloxacin.S.maltophilia presented high resistantce to carbopenems and aminoglycoside antibiotics.CONCLUSIONS Nosocomial S.maltophilia infection is associated with the severity of preoperative underlying heart diseases,prolonged mechanical ventilation and longer period of broad-spectrum antibiotic therapy,especially carbopenems antibiotics.

The HSS found in the cytosol of new-born calf liver was heat-stable and it promoted the DNA-synthesis of guinea-pig liver cells (P/o:5.72),HSS was also found in the cytosol of new-born rat livers,and its most effective concentration to promote incorporation of H2-TdR into DNA of guinea-pig liver cells was about 0.05mg/ml.This activity was reduced with both the increase and decrease of cytosol content,and the reason was not clear.It was proved with SDS-PAGE that the molecular weight of the active component was about 14000 and 23000 daltons.The cytosol from control rat livers showed no HSS activity and also no component measuring 23000 daltons.It needs further identification that the 23000 daltons protein is the active component in the cytosol of new-born calf and rat livers and the partially hepatectomized rat livers,but not in the cytosol of control rat livers.This finding indicateds that the livers of new-born calf and rat contain highly active HSS and are a valuable resource of HSS

0.05). Conclusion When TOFR recovers to 0.55,antagonism of residual neuromuscular blockade is still necessary.Different doses of neostigmine may antagonize vecuronium-induced residual neuromuscular blockade,and lower dose of neostigmine(10-20 ?g/kg) is recommended.

Objective To systematically review the efficiency of 18 F-FDG PET in glioma grading by using Meta-analysis. Methods Retrieval in PubMed and China National Knowledge Infrastructure (CNKI)was performed. Relevant papers concerning with glioma diagnoses with 18 F- FDG PET were selected. Paper quality was evaluated according to the standard of diagnostic test recommended by Cochrane Workshop. The data of glioma malignancy degree defined as semi-quantitatively and qualitatively were extracted from the papers. Meta-analysis was conducted with the Meta-Disc software to calculate pooled weighted sensitivity and specificity with 95% confidence interval (CI). Summary receiver operating characteristic (SROC) curve was performed and the areas under the curve (AUC) were calculated. Results Seven hundred and fifty-three patients from 17 papers ( 16 in English, 1 in Chinese) were included. Two hundred and seventy-two patients from 11 papers were using semi-quantitative (tumor to cortex ratio, T/C; tumor to white matter ratio,T/W) method and 481 patients from 9 papers were using qualitative method (visual observation, some of the papers had 2 or more methods). After heterogeneity test was done, different effect models were selected. The pooled weighted sensitivity, specificity and diagnostic odds ratio (DOR) with 95% CI for T/C group was 0. 952 (95% CI: 0. 903 -0. 980), 0. 409 (95% CI: 0. 318-0. 504) and 11. 746 (95% CI:5. 368-25. 702) respectively. The pooled weighted sensitivity, specificity and DOR with 95% CI for T/W group was 0. 857 (95% CI: 0. 768-0. 922), 0. 538 (95% CI: 0. 431 -0. 642) and 22. 066 (95% CI:7. 077-68. 800) respectively. The pooled weighted sensitivity, specificity and diagnostic odds ratio (DOR)with 95% CI for qualitative method was 0.810 (95%CI: 0.757-0.855), 0.870 (95%CI: 0. 819-0.911 ) and 15.282 (95% CI: 3. 716-62. 851 ) respectively. The AUC for T/C group, T/W group and qualitative method was 0.8604, 0. 8373 and 0. 8724 respectively. Conclusions Grading glioma by 18 F-FDG PET with semi-quantitative method may provide high diagnostic sensitivity. If qualitative method is used, the diagnostic specificity may be higher.
