Objective To study the rule of dynamic change of cognitive function in community elderly and predicting for dementia through using items of MMSE. Methods A 10 year follow up of cognitive function survey was carried out in the non dementia old people using Chinese version Mini Mental State Examination(MMSE). The elder people were divided into two groups (dementia group and non dementia group) according to the DSM Ⅲ R diagnostic criteria 10 years later. Results (1) A total of 1 192 subjects completed all data sheets by two surveys and 124 cases(10 4%)were identified in the second survey 10 years later. (2)Almost all the baseline item scores and its change of MMSE of the dementia group were higher than that of the non dementia group. (3)Orientation of time, serial subtration by seven, reading items of MMSE were effective predictors for the dementia, resding and orientation of time were significant predictors for Alzheimer's disease through logistic regression model. Conclusions The item analysis of MMSE is important information for the epidemiological research.

Objective 　To explore the relationship between psychosocial factors and risk of vascular dementia. Methods　A cohort study of people 55 years old and over were followed up 10 years after a baseline screening. 5055 older subjects in Shanghai were stratified and cluster sampled from community. Information about psychosocial factors was collected during the baseline screening with an interview in 1987. The clinical diagnosis of dementia and vascular dementia (VD) were made according to DSM-Ⅲ-R and Hachinski Ischemic Score (HIS). In 1997,the elders who were not having dementia in 1987 were surveyed; Clinical diagnosis terms of that was made in above mentioned criteria. Then we analyzed the relationship between the psychosocial factors and VD in community elderly population by means of Logistic regression and estimated the incidence of VD.Results　1203 subjects were re-surveyed in 1997 and among them 124 new cases of dementia including 36 cases of VD were identified. By calculating the relative risk (RR) of psychosocial factors to the VD, we found that several psychosocial factors were correlated with the VD including not taking group activities, unsatisfying life, negative life events and depression (RR＞1). ADL total score are also good predictive points for VD.Conclusions　Psychosocial factor may play an important role in the vascular dementia developed.

Objective To optimize the antibacterial drug regimen in ICU common staphylococcal infection.Methods The pharmacokinetic and pharmacodynamic parameters of antibacterial drugs were collected in combination with the hospital ICU anti-microbial drug resistance monitoring reports from the national antimicrobial resistance investigation net (Mohnarin)of the Ministry of Health and the performance standards for antimicrobial susceptibility testing (2013)issued by the clinical and laboratory stand-ards institute (CLSI),the minimum inhibitory concentration (MIC)of staphylococci was set by using the discrete uniform distribu-tion method and 16 kinds of administration regimens with 6 antimicrobial agents were worked out.The best initially antimicrobial regimen was optimized by using the pharmacokinetic and pharmacodynamic models and Monte Carlo simulations of cumulative frac-tion of response (CFR)from 5 000 patients.Results The alternative initially drug regimens to the infectious bacteria were:linezolid 0.40 g twice daily and vancomycin 0.75 g twice daily for staphylococcus aureus;amikacin 0.60 g once daily and linezolid 0.40 g twice daily,and vancomycin 0.75 g twice daily for hemolytic staphylococci and staphylococcus epidermidis;linezolid 0.40 g twice daily and vancomycin 0.75 g twice daily for methicillin-resistant Staphylococcus aureus;ampicillin/sulbactam 1.50 g 4 times daily, cefuroxime 0.75 g 4 times daily,amikacin 0.60 g once daily,moxifloxacin 0.40 g once daily for methicillin-sensitive staphylococcus aureus.Conclusion In the Staphylococcus aureus infection occurred in ICU,if which being methicillin-sensitive could be deter-mined,ampicillin/sulbactam,cefuroxime,amikacin and moxifloxacin could be selected for treatment,and linezolid or vancomycin could be selected for treating possible methicillin-resistant Staphylococcus aureus infection or undetermined whether being methicil-lin-resistant Staphylococcus aureus infection.

Objective To evaluate the utility of multi-slice computed tomography (MSCT) in assessing acute non-reperfused myocardial infarct size. Methods Seven domestic pigs (mean weight 17.3 ± 1.9 kg) underwent ligation of the distal left anterior descending artery to establish a model of acute myocardial infarction (MI). MSCT and triphenyltetrazolium chloride (TTC) staining were performed two hours later. The following data were acquired and analyzed:MI volume (%), CT values of the infarcted region, left ventricular cavity and normal cardiac tissue at various scanning time-points (1, 5, 10, 15, 20 min after contrast injection). Results Using MSCT, the overall MI volume showed a time-dependent decrease, with a reduction of 28.87%after 20 min. The greatest reduction occurred at the 5 min time-point. In TTC staining, MI volume was 9.87%± 2.44%. When MI size, as determined by MSCT, was compared with that by TTC staining in Bland-Altman plots, there was a better agreement at 5, 10, and 15 min time-points at 1 and 20 min. Conclusions The study indicates that double-phase scanning examination using MSCT is a useful tool to assess MI size, and the optimal late-phase scanning time-point set within 5-15 min of contrast injection.

Objective:Based on the construction of benign organizational climate of tertiary public hospitals, this paper tries to understand the practical demands of hospital staff for the internal organizational climate.Methods:A seven-dimension organizational climate questionnaire for public hospitals was designed by literature review and Delphi expert survey method. On the basis of satisfying the reliability and validity test, Kano questionnaire analysis and Better-Worse coefficient analysis were combined to identify the key climate factors to improve the satisfaction of hospital staff.Results:28 climate indicators were divided into: 9 (32.1%) attractive requirements, 7 (25.0%) one-dimensional requirements, 4 (14.3%) hybrid requirements, 6 (21.4%) must-be requirements, and 2 (7.2%) indifference requirements.Conclusions:According to Kano model classification results and satisfaction influence matrix distribution results, Some suggestions are put forward for constructing benign organizational climate in hospitals from the aspects of constructing equitable system, popularizing democratic leadership, attaching importance to cultivating scientific research and improving humanistic care.

Objective:To investigate the intervention effect of binary coping strategy based on systemic interaction model on the postoperative survival quality of patients with oral cancer.Methods:A total of 99 patients with oral cancer admitted to the Department of Oral and Maxillofacial Surgery of a tertiary hospital from Jun 2021 to Jun 2022 was selected.They were randomly divided into the control group(50 cases)and the observation group(49 cases)with random number table method.The control group received routine nursing for oral cancer.On this basis,the observation group also received the binary coping strategy based on the systemic interaction model.The scores of UW-QOL quality of life scale and binary coping scale were compared between the two groups before surgery,at the 3rd and 9th weeks after surgery.Results:The UW-QOL scores of both groups at the 3rd and 9th weeks after surgery were lower than those at admission,and the UW-QOL score in the control group was lower than that in the observation group(P＜0.05).At the 3rd week after surgery,the score of coping with the partner in the observation group was higher than that in the control group(P＜0.05).At the 9th week after surgery,the total score,negative coping,stress communication,coping together,and supportive coping scores in the observation group were higher than those in the control group(P＜0.05).Repeated measures analysis of variance showed that there was an interaction between time and group for the total score of binary coping scale(P＜0.05).And there was a significant main effect of time and group on the total score of binary coping scale(P＜0.05).Conclusions:The quality of life of patients with oral cancer is poor.The binary coping strategy based on the systemic interaction model can improve the quality of life of patients,enhance the intimacy of patients with their partners,and contribute to the disease recovery of patients with oral cancer.

ObjectiveTo investigate the efficacy and safety of CalliSpheres microsphere-transcatheter arterial chemoembolization (CSM-TACE) versus conventional transcatheter arterial chemoembolization (cTACE) in the treatment of hepatocellular carcinoma (HCC) through a meta-analysis. MethodsPubMed, Web of Science, Cochrane Library, CNKI, Wanfang Data, and VIP were searched for all Chinese and English articles on the application of CSM-TACE and cTACE in HCC published up to the end of October, 2020. After quality assessment was performed for the articles included, RevMan 5.3 software provided by Cochrane Library was used for analysis. ResultsA total of 15 studies were included, with 1535 patients in total. This meta-analysis showed that compared with the patients receiving cTACE, the patients receiving CSM-TACE had significantly higher 1-year overall survival rate (odds ratio ［OR］=2.26, 95% confidence interval ［CI］: 1.63-3.13, P＜0.000 01), 2-year overall survival rate (OR=1.73, 95%CI: 1.20-2.50, P=0.003), and 2-year progression-free survival rate (OR=1.60, 95%CI: 1.05-2.43, P=0.03). In terms of safety, compared with the patients receiving cTACE, the patients receiving CSM-TACE had significantly lower incidence rates of postoperative vomiting (OR=0.65, 95%CI: 0.46-0.92, P=0.01), bone marrow suppression (OR=0.17, 95%CI: 0.05-0.54, P=0.003), and neutropenia (OR=0.18, 95%CI: 0.07-045, P=0.000 3), while there were no significant differences between the two groups of patients in postoperative pyrexia, abdominal pain, and ascites (all P＞0.05). ConclusionCSM-TACE has significant advantages in improving 1- and 2-year overall survival rates and 2-year progression-free survival rates and can significantly reduce the incidence rates of postoperative vomiting, bone marrow suppression, and neutropenia. Therefore, CSM-TACE is a safe and effective treatment method.
