Objective: To investigate the diagnostic value of combined examination of copeptin and high sensitivity cardiac troponin T (hs-cTnT) in patients at the early stage of acute myocardial infarction (AMI) . Methods: A total of 272 patients were enrolled in this study, all of them suffered from chest pain and admitted within 4 hours. The patients were divided into 4 groups according to coronary artery angiography (CAG) results. Control group, the patients with normal CAG,n=64, UAP group (unstable angina pectoris),n=50, STEMI group,n=82, NSTEMI group,n=76. All patients received in-hospital observation, plasma levels of copeptin and hs-cTnT were examined at admission and at 6 hours after the chest pain respectively. Results: Within 4 hours of chest pain, combined examination of copeptin and hs-cTnT had the higher sensitivity for diagnosing AMI than a single detection of hs-cTnT with the cut-off point of hs-cTnT ≤ 14ng/L and Copeptin < 14pmol/L. In NSTEMI group, the AUC (area under curve) for combined examination was 0.97 (95% CI 0.88-0.99), AUC for single hs-cTnT detection was 0.75 (95% CI 0.62-0.87),P<0.05. In STEMI group, the AUC for combined examination was 0.97 (95% CI 0.88-0.99), AUC for single hs-cTnT detection was 0.74 (95% CI 0.60-0.88),P< 0.05. The AUC for combined examination of copeptin and hs-cTnT in diagnosing early AMI was 0.912 (95% CI 0.812-0.961) which was higher than single detection of hs-cTnT, AUC 0.851 (95% CI 0.713-0.936), Z=2.553,P<0.05. Conclusion: Combined examination of copeptin and hs-cTnT had the higher sensitivity and accuracy for diagnosing the patients at the early stage of AMI, it may help the risk stratiifcation of chest pain which is valuable in clinical practice.

Five compounds were isolated from the rhizome and roots of Rhodiola crenulata S.H.Fu.They werc identified as rhodionin (Ⅰ), rhodiosin(Ⅱ), tyrosol(Ⅲ), salidroside(Ⅳ) and gallic acid (Ⅴ), respectively, by UV, MS, 1H and 13CNMR spectroscopic and chemical reactions.

The new cataloguing rules, RDA, have been implemented in NLM and more RDA bibliographic data can thus be accessed in domestic medical libraries when the Western documents are catalogued by offloading their bibliographic data.The differences in RDA and AACR2 were compared, the common modified fields and descrip-tive contents were described when the RDA bibliographic data were changed into AACR2 bibliographic data in order to provide certain reference for cataloguing of Western documents using the RDA bibliographic data.

Objective To investigate quality of life and its influencing factors among elderly women with urinary incontinence(UI) living at nursing homes in Beijing. Method A randomized method was used to select six districts in Beijing. All the nursing homes in these 6 districts were included in our study,642 eligible elderly women participated in the survey. Quality of life of 244 women who were identified with different type UI were assessed. Bivariate analysis and multiple analysis were performed. Results The average score of quality of life was 8.5 ± 6.6. Scores of social embarrassment, activity & limiting behavior, psychosocial impacts were 1.8 ± 1.4,4.0 ± 3.5 and 3.3 ± 2.7 respectively. In bivariate analysis, significant differences were found by type of UI, severity of UI,course of UI, health condition, income level and self-care ability. In multiple analysis after adjustment of other variables, UI course≥5 years and inability to take care of herself were risk factors of quality of life.Conclusion Quality of life of elderly women with UI is poor, specific nursing and treatment should be conducted.

Objective To explore whether lymphovascular invasion can be used as a prognostic indicator in patients with bladder cancer underwent radical cystectomy.Methods The series included clinical data of 459 patients who had underwent radical cystectomy for bladder cancer between January 2006 and December 2012 in our hospital.Among all the patients,391 were male while 68 were female.Pathological grade G1 was diagnosed in 47,G2 in 104 and G3 in 308.Amount of pathological stage T1 or Tis or Ta or T0 was 167,T2 127,T3 89 and T4 76.Of all the patients,92 had lymph node metastasis.Follow-up time was between 13 and 99 months.The presence or absence of lymphovascular invasion was determined by HE staining in the radical cystectomy specimen.The x2 test was used to detect the association between lymphovascular invasion and several clinicopathological features,the Kaplan-Meier method was used to compare recurrence-free survival according to findings of lymphovascular invasion in the surgical specimen,and the multivariate Cox proportional-hazards regression model was used to assess the prognostic significance of some factors.Results Lymphovascular invasion was detected in 128 (28％) specimens.Among them,44 (34％) had tumor recurrence.Lymphovascular invasion was significantly associated with gender,tumor grade,pathological stage,lymph node metastasis and disease recurrence.Recurrence-free survival in patients without lymphovascular invasion was significantly higher than that in those with lymphovascular invasion (P＜ 0.05).Cox proportional hazards model showed that age,pathological stage and lymph node metastasis were independent predictors for disease recurrence.Conclusion In patients with bladder cancer underwent radical cystectomy,lymphovascular invasion may have a significant association with some prognostic parameters,but it can not be used as an independent predictor of disease recurrence.
