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.

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.

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.

Objective To investigate the detection results of GHB with different instruments, and to provide reliable basis for improving the accuracy of GHB detection. Methods ADVIA 1650 biochemical analyzer and HA-8160 glycosylated hemoglobin analyzer were used. The accurate detection of glycosylated hemoglobin in 100 healthy people was carried out, and the related data were recorded and analyzed statistically. Attention should be paid to this group according to glycosylated hemoglobin detection value, that is, within 6.5％ for A group, 6.5％-10.0％ for B group, more than 10％ for C group, and compare the above-mentioned different grouping of corresponding instrument glycosylated hemoglobin detection value. Results The analysis showed that there was no significant difference between the two groups of C instrument glycosylated hemoglobin levels, but the level of glycosylated hemoglobin detected by A in group HA-8160 and group B was significantly higher than that of ADVIA 1650(P<0.05). Conclusion Different instruments have some differences in the detection value of glycosylated hemoglobin. Clinicians should judge the disease comprehensively according to the actual situation and other indicators.

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 investigate the clinicopathologic characteristics and etiological factors of cervical cancer in young Uygur women in Xinjiang.Methods" We reviewed 350 cases of young Uygur females diagnosed with cervical cancer in our hospital during 1998-2007.The patients were divided into two groups according to their admission time (1998～2002 group and 2003～2007 group).Results: The incidence of cervical carcinoma among yong Uygur women was 12.9% in the 1998-2002 group and 10.3% in the 2003-2007 group.The first symptom was vaginal contactive bleeding.In both groups, most patients were peasants, but the percentages of highbrow was higher in the 2003-2007 group.Patients in the 2003～2007 group were of older age at first marriage and had lower rate of abortion.There was no significant difference in histological type between the two groups.However, patients in the 2003-2007 group presented with much earlier stage of cervical cancer and 56.9% of them were of stage Ⅱ disease, compared with 18.1% in the 1998-2002 group (P<0.05).Squamous cell carcinoma was the dominant histological type.Conclusion: The incidence of cervical carcinoma in young Uygur women tends to decrease due to screening and advocation of late marriage, less reproduction in remote rural areas of Xinjiang.
