Objective: To study the relationship between negative behavior of preschool children and behavior of their mothers. Method.. 742 mothers of children in their 3 ～ 6 year old age were tested by self- made questionnaire. Results: Negative behavior was not significantly related to age and gender of children. It was negatively related to maternal supporting behavior and positively to maternal un- supporting behavior. The culture background (urban/rural), family income and mother' s occupation were found to be important factors mediating maternal un- supporting behavior. Conclusion: Negative behavior of preschool children is influenced by mother' s behavior, which in turn has its cultural - economical background.

Objective:To investigate the routine maintenance and inspection methods of magnetic resonance imaging (MRI) equipment, reduce the failure rate and improve the image quality, and ensure the normal operation of medical image diagnostic equipment.Methods:According to the characteristics of the equipment, to make maintenance inspection goals and complete the daily management of MRI equipment. According to the medical equipment management system requirements, to establish and maintain records to provide data to meet the requirements and the effective operation of quality management system, and to record the data for each equipment for continuity and traceability.Results: There are the potential problems through the management and analysis of MRI equipment data. And the problems were timely solved to make the device operate steady. It’s easy to get a clear and reliable image and to provide an objective and true diagnostic basis for clinical.Conclusion: The routine maintenance and inspection of MRI equipment is an indispensable and important work in medical engineering.

Objective To understand the current situation of multidrug-resistant organism (MDRO)infection in hospitalized patients in a tertiary first-class hospital,as well as efficacy of bundle intervention measures on preven-tion and control of infection. Methods Hospitalized patients who were infected with MDROs in this hospital during 2012-2014 were monitored and conducted bundle intervention. Results In 2012-2014,a total of 1909 MDRO strains were isolated. The isolation rates of MDROs in 2012-2014 were 30.69% ,31 .04% ,and 29.40% respec-tively,bedside intervention rates were 81 .02% ,92.05% ,and 94.23% respectively,implementation rates of clinical isolation were 69.97% ,82.98% ,and 93.04% respectively;MDRO isolation rates during 2012-2014 were not sig-nificantly different(P>0.05);bedside intervention rates and implementation rates of clinical isolation were both sig-nificantly different(both P<0.05). The top 3 isolated MDROs in 2012-2014 were extended-spectrumβ-lactamases (ESBLs)-producing Escherichia coli,multidrug-resistant Acinetobacter baumannii,and ESBLs-producing Klebsiel-lapneumoniae. Conclusion Bundle intervention measures,such as multi-department collaboration and strengthened on-site supervision,can promote more standardized management of healthcare-associated infection,enhance the im-plementation rate of clinical isolation,and effectively prevent and control the spread of MDRO in hospital.

Objective: To investigate the relationship between serum albumin level and severity of coronary heart disease (CHD). Methods: A total of 237 patients admitted in our hospital from 2008 to 2009 and undergoing coronary angiography were enrolled. CHD severity was evaluated according to clinical types, number of diseased coronary vessels and coronary artery score respectively, and patients were divided into non-CHD group (n=84), angina pectoris group (n=92) and myocardial infarction group (n=61). Serum total protein, albumin and globulin were measured in all patients on second day after admission. Relationship among indexes of CHD severity and serum proteins were analyzed. Results: Compared with non-CHD group, there was significant decrease in albumin level [(40.22±3.56) g/L vs. (39.81±3.56) g/L vs. (38.68±3.43) g/L, P<0.05] in angina pectoris group and myocardial infarction group. Spearman correlation analysis indicated that serum albumin level was significant negatively correlated with clinical types (r=-0.18, P=0.005), number of diseased coronary vessels (r=-0.195, P=0.003) and coronary artery score (r=-0.188, P=0.004). Serum total protein, globulin and ratio of albumin/globulin were not significantly correlated with clinical types, number of diseased coronary vessels and coronary artery score (P>0.05). Conclusion: Serum albumin level is negatively correlated with severity of coronary heart disease. Low serum albumin may be a risk factor for coronary heart disease.

Objective To observe the clinical effects of invigorating the spleen promoting blood flow and removing stasis therapy on hypertension .Methods 104 subjects were randomly divided into 2 groups :control group ,including 52 cases ,which was treated by Benalapril and treatment group ,including 52 cases ,which was treated by Benalapril and herbs ,with a course of 4 weeks .The clinical symptom score ,blood rheology were observed .Results The total effective rate was 92 .31% in treatment group ,which was higher than that in control group ,whose effective rate was 76 .92% (P<0 .05);Improvement of the clinical symptoms and blood rheology were better in treatment group than in control group(P<0 .01) .Conclusion This therapy is quite effective for hyperten-sion and can reduce blood lipid and improve blood rheology .

Epilepsy was arousing the attention of medical circles because of the complexity of its mechanism and the difficulty of its control.The project which used the pioneering research as the basement and was directed by the chinese medicine used the modern multidisciplinary research technologies and explored the mechanism of the brain damage in epilesy.The project′s treatment idea is different from the others,which provided a new way for seeking new medicines for treating epilepsy.The research techniques took use of the application of the behavioral methods and the electrophysiological methods creatively and the subject firstly used this way to observe it dynamically,which greatly improved the accuracy of evaluating the models and pharmacodynamics studies of the epilepsy.The research method of the project firstly observed the changing mechanism of the brain damage and the regulation of the apoptosis related genes,and even the efficiency of tsaoko-anemarrhenae decoction,which enriched the scientific intension of the decoction.The conclusions palyed a very important role in exploiting the new medicine for treating epilepsy and enriching the knowledge of the five visceras in chinese medicine.

Objective:To describe the status of self-rated health(SRH)among the elderly and find out the relationship between SRH and other health measures such as two weeks prevalence and chronic disease prevalence.Methods:The data used was generated from cross-sectional household health survey conducted in the year of 2009 in Shunyi district,Beijing.SPSS software was used to conduct univariate and multivariate liner regression analysis with self-rated health.Results:The average score of self-rated health among the elderly is 72.49.Univariate analyses suggest that are age,sex,marital status,income level,education,employment,medical insurance type,self-perceived anxious or depression,disease state are all associated with poor SRH score.Multiple liner regression model shows that age,job,medical insurance,self-perceived anxious or depression,suffer from two-week illness and chronic disease had effects on SRH of the elderly.Conclusion:Physical and psychological unhealthy are independent risk factors of SRH among the elderly,disease status is the most influential predictor on SRH score.Thus,a single measurement of SRH question can be used in health status assessment of the elderly.

Objective The aims of the present study are to further investigate mechanism of toxicological role of sulfur dioxide (SO 2) exposure on mammalian animals Methods Effects of SO 2 inhalation (14 mg/m 3) on activities of antioxidative enzymes and levels of lipid peroxidation in erythrocytes of male rats were determined Results SO 2 inhalation caused the decrease of Cu,Zn SOD activity,the increase of GSH Px activity,and no change of CAT activity,and the increase of level of lipid peroxidation in rat erythrocytes Conclusion Primary mechanism of toxicological role of SO 2 exposure at low concentrations may be that oxidation damages of lipid and other biological large moleculars are caused by SO 2 producing reactive oxygen species
