Objective To investigate the relationship between serum levels of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMP) and the mortality in patients with malignant middle cerebral artery infarction.Methods A total of 74 patients with malignant middle cerebral artery infarction (MMCAI) was assigned to research group,74 healthy volunteers were recruited to serve as healthy controls,and 242 patients with other cerebral infarction were recruited to serve as case controls.Quality-of-life questionnaire and clinical examination were used to collect the information of participants.Endpoint was 30-day mortality.Results The research group showed higher serum levels of MMP-9,MMP-10,and TIMP-1 relative to the case control group,and the case control group showed higher serum levels of MMP-9,MMP-10,and TIMP-1 relative to the healthy control group (P ＜ 0.05).Compared to survivor ones,non-surviving MMCAI patients showed lower Glasgow Coma Scale score (P ＜ 0.05),higher serum levels of tumor necrosis factorα (TNF-α),MMP-9,MMP-10,and TIMP-1 (P ＜ 0.05).Multiple logistic regression analysis showed that serum levels of TNF-α,MMP-9,MMP-10,and TIMP-1 were associated with 30-day mortality,and the OR were 1.09,1.18,1.13,and 1.32,respectively.Conclusions Serum levels of MMP-9,MMP-10,and TIMP-1 levels in MMCAI patients were associated with mortality,and could be used as an auxiliary index of mortality in MMCAI patients.

Objective To evaluate the curative effect of normobaric oxygen therapy on fetal atrial premature contractions(PACs) with Doppler ultrasound. Methods Maternal normobaric oxygen therapy was performed in one hundred and seventy three fetus with PACs but without congenital heart disease diagnosed by Doppler echocardiography. Another 63 cases with isolated PACs receiving no therapy served as controls. Results (1) The average ratio of full recovery in the second course of treatment was 97.8 % in one hundred and seventy three fetus with PACs; (2) The valves′ regurgitation volume reduced or disappeared, the pericardial edema′s volume reduced or absorbed and the peripheral blood flow improved obviously (P

Objective To analyze the impact of health service and some other factors on the improvement of health. Methods The production function model introduced by Auster was employed. With the age adjusted mortality taken to be the output of health and factors like health service, life style, living environment, economy, and education taken to be the input, the two-stage least square was used to analyze the impact as well as the degree of the impact of the various factors. Results The impact of health service, the contribution of which to the age adjusted mortality was around 0.37, was greater than that of education but smaller than that of economy. Conclusion The result indicates that health service is an important influencing factor in the improvement of health. Full attention ought to be paid to it so that investment into health, especially public health, will be expanded and the health of the people better protected.

Information Dissymmetry is a common phenomenon in this economical market.None of us can master all information about anything.The relative difference of the information's occupancy leads to a sharp distinction of the bargainer' status currently.During the service of our hospital library,Information Dissymmetry seriously restricts the development of our library and makes many readers dissatisfied.The author analyzed the problem in progress of service to the reader and finally put forward the countermeasure of this progress reconstruction in the hospital library.

Objective To compare sequence analysis of the yeast-like fungal isolates with traditional methods and analyze the feasibility of identification of common yeast-like fungal by sequence analysis of gene. Methods 115 yeast-like fungal isolates were collected in the clinical laboratory of Beijing Tongren Hospital. DNA of yeast-like fungal was extracted and then amplified with universal primers of part of 18S rRNA genes followed by sequencing directly. The sequences obtained were submitted to the GenBank (NCBI) to identify the fungi. At the same time, the CHROMagar Candida and Vitek 32 YBC were used to identify the fungi. The identification accuracy with three methods was compared to explore the feasibility of the identification of sequence analysis. Results 18S rRNA gene sequence analysis was compared with traditional method. There were some differences in the identification results of 13 strains. The coincidence rate between CHROMagar Candida and sequence analysis was 89. 2% (91/102) and the coincidence rate between Vitek 32 YBC and sequence analysis was 91.3% (105/115). The positivity rate of species-level identification by CHROMagar Candida , Vitek 32 YBC and the 18S rRNA gene sequence analysis were 88. 7 % ( 102/115 ), 100% ( 115/115 ), 100% ( 115/115 ). Conclusion Identification of medically important yeast-like fungal by sequence analysis of the 18S rRNA gene is reliability.

Objective:To investigate the role of monocyte chemoattractant protein-1 in the progress that isometric exercise training improves arteriogenesis.Method:Twenty-four male Sprague-Dawley rats were used,weighing (200±20)g.The rats were randomized into control group (CG),myocardial ischemia group (MI),exercise training group (ET),MCP-1 inhibitor group (LG).There were 6 rats in each group.Rats were continuously administered 10mg/kg subcutaneously isoproterenol for successive 2 weeks to establish the myocardial ischemia model.Successfully modeled rats were in groups MI,ET and LG.Isometric exercise training were performed in group ET and LG.The rats in group LG were given MCP-1 inhibitor leflunomide by gavage.After 8 weeks of training,the left ventricular myocardium was extracted and relative collateral blood flow (RCBF) was measured by microspheres.Artery density (AD) and monocytes were measured by immunohistochemistry analysis.Western blot analysis and real-time quantitative PCR were performed to assay protein and mRNA of MCP-1.Result:RCBF and AD increased significantly in group ET as compared to the rest groups.RCBF and AD in group LG showed higher than that in group MI but not significant.The number of monocytes,MCP-1 mRNA and MCP-1 expression were significantly elevated in ischemic myocardium of group ET.Interestingly,the number of monocytes,MCP-1 mRNA and MCP-1 expression showed lower than that in group MI but also not significant.Conclusion:Eight weeks of isometric exercise training can increase the expression of MCP-1 in ischemic myocardium and promote the arteriogenesis.

To analyze the change of physiological indices in male and female pilot students during lower body negative pressure (LBNP) exposure, one female group and one male group participated in the experiment. They were subjected to LBNP up to 50 mmHg for 8 min. Electrocardiogram (ECG), heart rate (HR), blood pressure (BP), cerebral blood flow (CBF) and time of exposure were monitored during LBNP. The results showed that during LBNP, heart rate (HR) increased while systolic blood pressure (SBP) and cerebral blood flow (CBF) decreased with the prolongation of exposure. It is concluded that LBNP exposure could produce similar physiological changes in both male and femal pilot students.
