1.Diagnostic Value of Combined Examination of Copeptin and High Sensitivity Cardiac Troponin T in Patients at Early Stage of Acute Myocardial Infarction
Chinese Circulation Journal 2014;(10):772-775
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 provide the service for scientific innovation and competition in biomedical industry of Hunan Province and the reference for working out biomedical patent strategies.Methods The data of biomedical patents in Hunan Province were collected using the patentEX and processed by metrics.Results The application number of patents increased from year to year with a high expiry rate.The technology of biomedical patents has entered into its mature period and the application of patents was focused on several important IPC classifications.Conclusion Tra-ditional technologies play a main role in biomedical industry of Hunan Province, but Hunan Province is relatively backward in modern biological technologies.The application number of invented biomedical patents is rather large, but their overall academic level is rather low.The majority of biomedical industry enterprises lack of competition awareness.It is thus necessary to strengthen the development of modern biological technologies, improve the aca-demic level of biomedical patents, increase the competition awareness of biomedical industry enterprises, lay stress on cooperative development of biomedical patents and on support of biomedical industry enterprises.

Objective To evaluate prevalence and risk factors of urinary incontinence(UI)among aged women living at nursing homes in Beijing,and provide references of relative health strategy.Methods Totally 642 women aged 60 years and over were randomly selected at nursing homes from 6 districts in Beijing.A questionnaire survey was conducted using International Consultationon Incontinence Questionnaire Female Lower Urinary Tract Symptoms Module (ICIQFLUTS) recommended by International Consultation on Incontinence (ICI).Results The prevalence rate of UI was 38.0% (244/642) among whom 38.5% (94/244) of participants knew their health conditions,7.8% (19/244) visited hospital and 6.6% (16/244) received medical or operational treatment.The proportions of respiratory disease ( 27.0 % vs.14.6%),digestive disease (23.4%vs.15.3%),urological disease(24.6%vs.8.5%),cardio-cerebralvascular disease(74.2% vs.53.5%),neurological disease ( 9.4 % vs.5.0%),obstetric disease ( 27.5% vs.10.1%),menstrual disorder (21.4%vs.14.4%),getting married before aged 21 years (51.5%vs.40.8%),being pregnant more than 4 times(50.2%vs.40.9%),the experience of both cesarean and natural birth (4.0%vs.0.8%),constipation(40.2% vs.29.4%),fecal incontinence ( 13.1% vs.4.0%),uneasy movement ( 22.5%vs.10.6%) and drinking (8.6%vs.3.5%) were higher in women with UI than in women without UI (P<0.05 or P<0.01).Eight risk factors that were entered into logistic regression model included getting married before 21 years old (OR =1.5,95 % CI:1.0-2.3,P<0.05),being pregnant more than 4 times(OR=1.7,95%CI:1.1-2.4,P<0.05),menstrual disorder(OR=1.7,95%CI:1.0-2.7,P<0.05),respiratory disease(OR=1.6,95 %CI:1.0-2.6,P<0.05),urological disease(OR=2.4,95 %CI:1.4-4.1,P< 0.01 ),cardio-cerebralvascular disease ( OR =2.0,95 % CI:1.3-3.0,P < 0.01 ),obstetric disease(OR=3.4,95%CI:2.0-5.6,P<0.01),moving uneasily(OR=2.5,95%CI:1.5-4.0,P<0.01).Conclusions UI is a common disease among women residing at nursing homes.Specific measures including intervention and clinical treatment targeting risk factors should be conducted.
