Objective To understand the prevalence rate of mild cognitive impairment (MCI) and its related factors in community elderly so as to provide evidence for the community intervention. Methods A cross-sectional study was performed in a random sampling of 925 elderly people. Mini-mental state examination (MMSE), activities of daily living (ADL) scale and questionnaire were used for face-to-face interview. Chi-square test and logistic regression analysis were applied in this study. Results The prevalence rate of MCI was 21.1% in elderly people. Female, high age, illiteracy, loss of spouse, lack of exercise, no professional activitives and not doing some work for the descendants were the risk factors for MCI. Conclusions The aging and the low educational level are the risk factors for MCI in the elderly. High self-care ability scores are the protective factors for MCI.

Objective To evaluate the efficiency of inhaling penehyelidine hydyoehloride(PHC)in reducing pulmonary arterial pressure and improving lung funetion in patients with acute exaeerbation of ehronie obstruetive pulmonary disease(AECOPD).Methods Sixty patients with AECOPD were randomly divided into the control group(30 patients) and the treatment group(30 patients).The patients in treatment group inhaled PHC,and patients in control group inhaled diprophylline.The pulmonary arterial pressure was measured before and after inhalation.The peak expiratory flow(PEF) and forced expiratory volume in one second(FEV1)was measured at different time points before and after inhalation. Arterial blood gas and,symptoms were also observed.Results The pulmonary arterial pressure in treatment group was reduced by 20% and reduced by 5% in the control group.FEV1 and PEF were improved after inhalation,the average increase of FEV1 was 350 ml(P＜0.01),and PEF was improved by 37 L/min(P＜0.05).Arterial blood gas analysis was improved,and PaO_2 increased by 18 mmHg(P＜0.01).The respiratory rate and the symptoms of cough and sputum were also improved.Conclusion PHC improved the lung function of patients with AECOPD by reducing the pulmonary arterial pressure.

ObjectiveTo explore the effect of tracer methodology on management of high-risk medicine.Methods The management of high-risk medicine was investigated with tracer methodology to find out the problems in the medicine management, construct effective management system and establish tracer programme and pyramid management mode for high-risk medicine management.The rate of adverse events in high-risk medicine management before the use of tracer methodology was compared with that after the use.Result The incidence of adverse events was significantly lower than that before the use of tracer methodology (χ2=5.379,P<0.05).Conclusion The tracer methodology in the management of high-risk medicine can be effective in the reduction of incidence of adverse events in high-risk medicine management and promotion of safety management.

Objective To find out the living condition of the elderly adults and their needs for community bealthcare services so as to provide evidence-based guidance for our govemment. Methods A total of 925 participants aged ＞ 60 years were personally interviewed for questionnaire and ADL scale evaluation. Chi-square test and Kmskal-Wallis H test were used for data analysis. Results The subjects showed relatively lower education level and the illiteracy rate was high. Their marriage was stable and a decreased divorce rate was found. The economic situation was satisfactory. Their life satisfaction was farbeyond the health satisfaction. Most of the elderly did not live with their offspring,although 21.8% could not take care of themselves. The prevalence rate of chronic diseases was 81.5% ,which resulted in more demands for social activities, health consultation, rehabilitation nursing, and home healtheare services in the community. Conclusion They need to pay more attention to physical and mental health of the elderly. A community healthcare system that could provide services in an-all-round way,including medical care, should be established and improved.

Objective To evaluate the prevalence of obstructive sleep apnea syndrome (OSAS) and its characteristics in elderly patients with cardiovascular diseases, and provide reference for the clinical decisions. Methods All patients who were hospitalized in department of cardiovascular medicine from January to June in 2007 were invited to participate in the current study. A total of 317 hospitalized elderly patients were recruited into this study. All participants were assessed by portable bedside nocturnal polysomnograph and Epworth sleepiness scale (ESS). Results Among 317 patients, 281 cases (88.6%) met the criterion of obstructive sleep apnea (OSA) [apnea and hypopnea index (AHI)≥5] and 47 cases (14.8%) met the criteria of obstructive sleep apnea syndrome (OSAS) (AHI≥5 and ESS≥9). When the severity of OSA (as indicated by AHI) was considered as a dependent variable, multiple regression analysis indicated that it was significantly associated with minimal SaO2 and the oxygen desaturation index, while age, habitual snoring, ESS, BMI, mean SaO2 and the duration of SaO2≤ 90% did not show significant effects on the severity of OSA. Conclusions High prevalence of obstructive sleep apnea syndrome (with daytime sleepiness) is found in elderly hospitalized patients and the rate of obstructive sleep apnea is much higher in patients without daytime sleepiness symptoms. Minimal SaO2 and the oxygen desaturation index are the important predicting factors for the severity of OSA, while age, BMI, habitual snoring, sleepiness are not correlated with the severity of OSA after adjusting minimal SaO2 and oxygen desaturation index.

Objective To investigate the knowledge of chronic heart failure (CHF) and influencing factors in general practitioners (GP) in Beijing.Methods A self-designed questionnaire contained total 28 items,including basic knowledge of CHF,non-drug management,drug management and other management ; clinical cases were used to test clinical ability in 7 items.The questionnaire survey was conducted among GPs who participated in continuing education courses from 16 counties/districts in Beijing during January to June 2013.Results Total 720 questionnaires were distributed and 657 valid questionnaires were returned with a recovery rate of 91.3％.Total scores was 60.6.Scores of basic knowledge,non-drug management,drug management and other management was 63.1,76.9,44.0 and 56.9,respectively.There were statistical differences in scores of basic knowledge,non-drug management,drug management and other management between GPs with different diploma (F value:36.8,5.8,21.6,12.2,respectively; P ＜0.01) ; there were significant differences in scores of basic knowledge and drug management among GPs with different working years (F value:15.1 and 17.4,respectively ; P ＜ 0.01) ; there was significant difference in scores of drug management among GPs with different professional title (F =7.69,P ＜ 0.01).Only for GPs with junior college diploma,the scores of basic knowledge and drug management in GPs with working ≥20 y were higher than those working ＜ 20 y(P ＜ 0.01).The accuracy of clinical ability in GPs with junior college diploma,undergraduate diploma and post-undergraduate diploma was 39.6％,41.6％,41.8％ (P ＞ 0.05).Conclusions The knowledge of CHF is less desirable in GPs of Beijing,so that measures should be taken to improve the GP's knowledge of CHF.

In order to enhance the specificity of TNF-α monoclonal antibody to inflamed site, a bispecific antibody BsDb that targets TNF-α and the extra-domain B (ED-B) of fibronectin (FN) was constructed by covalently linking the anti-TNF-α single chain Fv antibody (TNF-scFv) and the anti-ED-B scFv L19 via a flexible peptide linker deriving from human serum albumin (HSA). ED-B is an antigen specifically expressed at the inflamed site. BsDb is expressed in E. coli, identified by immunoblot, and purified with affinity chromatography. This was followed by further examination of its bioactivities and pharmacokinetics. We demonstrated that BsDb retained the immunoreactivity of its original antibodies as it could simultaneously bind to TNF-α and ED-B and neutralize the biological action of TNF-α. In the collagen-induced arthritis mice model, BsDb selectively accumulate in the inflamed joint with a maximal uptake of (12.2 ± 1.50)% ID/g in a single inflamed paw and retain in the inflamed paw for at least 72 h. In contrast, BsDb showed a short serum half-life of (0.50 ± 0.05) h and a rapid clearance from normal tissues. The findings reported herein indicate that BsDb has good specificity to the inflamed site and low toxicity to normal tissues. BsDb is therefore likely to have greater clinical applications in the treatment of rheumatoid arthritis and other autoimmune diseases. This laid a stable basis for its preclinical study.

Objective To investigate the feasibility of Six Dimensions Scale (6-D scale) of Nursing Performance used for evaluating the effect of standardized hospital-department training on new graduate nurses.Methods 6-D Scale of Nursing Performance was conducted to evaluate the nursing ability of 216 new graduate nurses (2013) of our hospital pre and post the three-month intervention,including the self-appraisal and appraisals by head nurses.Results The nursing ability was improved significantly after the training.The total score of self-appraisal 6-D scale were significantly higher than that before the training (142.34±19.92 vs 135.81±18.30),in which the subscales scores within the dimensions of leader-ship,critical care,teaching/collaboration,planning/evaluation,interpersonal relations/communication were increased significantly,while the increase of professional development was not significant.Six-D Scale and six subscales scores based on self-appraisal were higher than that based on the head nurses' appraisals.Conclusions The application of 6-D scale is scientific to evaluate the effect of standardized nurse training.We had demonstrated that standardized hospital-department training is of great benefit for new graduates to improve the nursing ability and adapt to the clinical circumstances.

A survey on clinical knowledge of coronary artery disease (CAD) management in general practitioners (GPs) in Beijing was conducted from March to September,2013.The questionnaire contained 4 cases (stable angina pectoris,post-percutaneous coronary intervention,acute anterior myocardial infarction and acute inferior myocardial infarction) and related clinical questions.Five hundred questionnaires were distributed and 471 valid questionnaires were returned with a recovery rate of 94.2％.The correct rate was 87.3％ and 61.8％ for diagnosis and treatment of emergent events in acute anterior myocardial infarction; however,the correct rate for other knowledge was ranged between 23.4％ and 40.6％.The correct rate increased with the educational levels in 5/11 items(P ＜ 0.01)and increased with the professional titles(P ＜ 0.001)in 3/11 items,which was not associated with the attendance of training or frequency of training attendance.The results indicate that clinical knowledge of CAD management for GPs in Beijing should be improved and the training methods should be focused on the clinical capacity.
