Objective To investigate the effects of Qiliqiangxin capsule on serum concentration of adiponectin (APN) and heart function in patients with uremia combined with heart failure. Methods Uremia patients combined with heart failure were randomly divided into treatment group and control group , both of which were given anti-failure routine therapy. The patients in treatment group were treated with Qiliqiangxin capsule for 8 weeks and those in control group with placebo. The New York Heart Association (NYHA) heart function classi-fication, left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular ejection fraction(LVEF), and the levels of APN were observed before and after treatment. Results The level of APN in uremic patients combined with heart failure was significantly higher than that in normal subjects. With the increase in the class of NYHA heart function, the serum concentrations of APN increased, but the difference was not significant(P > 0.05). After 8 weeks′ treatment, the effective rate in treatment group was higher than that in control group (P < 0.05). LVEDD and LVESD in both groups decreased significantly. LVEF in both groups increased, but serum concentration of APN decreased significantly. More obvious effects were observed in treatment group (P < 0.05). Conclution Qiliqiangxin capsule could significantly reduce the level of APN and improve heart function in patients with uremia combined with heart failure.

Objective To test the reliability and validity of Chinese version of Stressful Life Events Questionnaire and the influence of preinjury stressful life events on the life quality and mood symptoms of the patents following cerebral concussion.Methods 285 patients with cerebral concussion were assessed by Stressful Life Events Questionnaire(SLESQ),PTSD Checklist civilian version(PCL-C),Thirty-Six-Item Short-Form Health Survey (SF-36),Hamilton Depression Rating Scale(HDRS),Hamilton Anxiety Scale(HAMA) at baseline.The patients had been reassessed with the HDRS,HAMA,SF-36 at 3 months after cerebral concussion.The hierarchical regression analyses were used to determine the influence of Stressful Life Events for the life quality and mood symptoms of the patient with cerebral concussion.Results The incidence of stressful life events was 42.8％.The multiple regression analysis showed the experience of stressful life events were the influence factor of scores on the SF-36,HDRS,HAMA after adjusted by the age,gender,education,income,social support,the scores of anxiety and depression before injury and the R 2 value of SLESQ to SF-36 physical health factor,mental health factor,HDRS,HAMA was 0.064,0.111,0.145,0.028,respectively.Conclusion The history of stressful events is the influence factor of the patient with cerebral concussion to have poor life quality and mood disorder.

Background and purpose:Radiotherapy and endocrine therapy are both important parts of adjuvant therapy for breast cancer, yet few studies have been conducted focusing on the interaction between radiation and endocrine therapy. Up to now, no conclusion has been drawn on the timing sequence of adjuvant radiation and endocrine therapy, which is indeed crucial in clinical practice. This study intended primarily to investigate the effect of concurrent or sequential exemestane combined with radiation on radiosensitivity of MCF-7 cells and its possible mechanism,and further to provide rationale for optimal clinical treatment modality.Methods:MCF-7 cells were arranged into three trial groups: the radiation group, exemestane sequenced with radiation group and exemestane followed radiation group. Radiosensitivity was evaluated by clonogenic assay, cell proliferation was measured by MTT assay, the ability to induce cell apoptosis was evaluated by DAPI staining assay, the changes of Bcl-2 and Bax were detected by Western blot.Results:Sensitive enhancement ratios (SER) were 1.51 and 1.37 in the exemestane sequenced with radiation group and exemestane followed radiation group, respectively. Compared with the radiation group, the percentage of cellular proliferation inhibition and apoptosis increased obviously in the exemestane sequenced with radiation group and exemestane followed radiation group. Exemestane combined with radiation made the Bax protein increase obviously and the Bcl-2 protein lowered significantly.Conclusion:Exemestane can enhance the radiosensitivity of MCF-7 cells, whose mechanism might be relevant to the promotion of cellular apoptosis. However,the treatment sequence does not affect the outcome.

OBJECTIVE: To discuss the evaluation of comprehensive benefit of hospital pharmacy department with comprehensive index method. METHODS: Suitable evaluation indexes on social effects and economic returns were respectively selected to be assigned with weight numbers by analytic hierarchy process, and the comprehensive benefits of pharmacy department in our hospital during the period from 2002 to 2004 were evaluated. RESULTS: The index values of social effects, economic returns and comprehensive benefits increased year by year, which was in line with the objective actuality. CONCLUSION: It is feasible to evaluate comprehensive benefit of hospital pharmacy department with comprehensive index method.

Objective To evaluate the effects of early and late tracbeostomy on patients with acute severe cerebral trauma.Methods In the retrospective study,167 patients with severe brain trauma ( GCS ＜ 9 ) requiring prolonged mechanical ventilation ( MV ) were managed by percutaneous dilational tracheostomy (PDT) from May 2001 to December 2010.According to the transoral incubation MV duration,the patients were divided into the early tracheostomy (ET) group ( MV duration≤7 d,81 cases)and late tracheostomy (LT) group (MV duration ＞ 7 d,86 cases).The basic clinical characteristics,pre-and post-PDT MV period,total MV duration,length of post-PDT ICU stay,length of ICU stay,length of hospital stay and mortality were compared between the two groups.Results The two groups showed no statistical differences in aspects of age,sex,acute physiology and chronic health evaluation Ⅱ (A-PACHE Ⅱ ) score,GCS,trauma index and craniotomy rate (P＞0.05).Compared with LT group,ET group significantly shortened the pre-PDT MV period [ (5.16 ± 1.33 ) d∶ ( 1 1.64 ± 4.25 ) d,P ＜ 0.01 ],post-PDT MV period ( median:15.0 d∶ 17.0 d,P ＜ 0.05 ),total MV duration ( median:18.0 d∶26.0 d,P＜0.05),length of post-PDT ICU stay (median:16.0 d∶21.0 d,P＜0.01 ) and length of ICU stay (median:21.0 d∶32.0 d,P ＜0.01 ).But the two groups had no statistical differences concerning the length of hospital stay ( P ＞ 0.05 ),ICU mortality ( 17％ ∶ 14％,P ＞ 0.05 ) and in-hospital mortality (25％∶28.4％,P ＞0.05).Kaplan-Meier curves showed that the frequency of MV and ICU stay rate within 60 days in ET group were significantly lower than those in LT group.Conclusions For patients with severe brain trauma,early tracheostomy shortens the duration of MV and length of ICU stay without affecting their prognosis.Thereby,tracheostomy can be performed at early stage when managing acute severe brain injury.

OBJECTIVE:To establish the method for the simultaneous determination of anticancer activity components of flavonoids from Hedyotis diffusa,i.e. quercetin,kaempferol. METHODS:HPLC was applied to determine the contents and performed on Alltima C18(250 mm?4.6 mm,5 ?m) column. Mobile phase consisted of methanol(A)-0.5% glacial acetic acid,(gradient elution). The detection wavelength was aet at 350 nm. RESULTS:The linear range of quercetin was 0.006 2～0.244 0 ?g(r=0.999 8)and that of kaempferol 0.007 8～0.310 6 ?g(r=0.999 9). The average recovery of quercetin was 101.84%(RSD=1.79%,n=6) and that of kaempferol 99.04%(RSD=2.90%,n=6). CONCLUSIONS:The method is simple,accurate and reproducible for the quality control of H. diffusa.
