Objective To investigate the effect and safety of urinary kallidinogenase on acute cerebral infarction.Methods One hundred and sixty-four patients with acute cerebral infarction were randomly divided into two groups:treatment group with urinary kallidinogenase(86 cases)and control group (78 cases).According to Chinese guidelines for prevention and management cerebrovascular disease,two groups were treated with basic therapy,such as antiplatelet,neurologic protection,blood pressure control,and so on.On basis of control group,treatment group Was administrated intravenous injection of urinary kallidinogenase 0.15 PNA U per day for 10 days.The primary efficacy Was evaluated by the National Institutes of Health Stroke Scale(NIHSS)score and Barthel index.Results The score of NIHSS and Barthel index at 15 days after treatment in the treatment group were higher than those in the control group[(6.67±3.02)scores vs(7.42±3.02)scores;75.36±23.56 vs 68.36±22.36,P＜0.05].Urinary kallidinogenase could significantly reduce neurological deficits in big artherosclerosis type by TOAST typing.Conclusion Urinary kallidinogenase may be effective and safe in the treatment of acute cerebral infarction.

Objective To provide evidence for diagnosis and treatment by investigating the pathogens and drug resistance of immunocompromised host (ICH)pneumonias.Methods Statistical method was used to analyze retrospectively the data of pathogens and drug resistance of ICH pneumonia treated in our hospital in 2014. Results We confirmed 187 cases of ICH pneumonia by pathogen study of 324 patients.Gram-negative bacillus (68.42%)was the main pathogen of ICH pneumonia.Acinetobacter baumanii (AB)accounted for the first place. Staphylococcus aureus infection was still the first of Gram-positive coccus.Conclusion Gram-negative bacillus was the main pathogen of ICH pneumonia in our hospital and the isolated bacteria show strong antibiotic resistance. Therefore,it is necessary to strengthen dynamic monitoring of pathogens in the secretions from ICH pneumonia patients’ lower respiratory tract and drug resistance.It is suggested that clinicians make anti-infection treatment cover drug-resistant bacteria.

The experimental group of 28 students used “one week with one case” teaching method with college-enterprise cooperation; the control group of 28 people used traditional “one week with one case”teaching method. The examination scores and questionnaire were used to evaluate the teaching effects.?RESULTS:The students of experimental group acquired higher test scores in short-answer questions and the case analysis questions compared with students of control group (P<0. 05). The questionnaire survey showed the“one week with one case” teaching method with college-enterprise cooperation acquired higher scores in 6 items which include the intensity of learning interest, information acquisition ability, team cooperation ability, communication skills, oral communication ability and the satisfaction of teaching method (P<0. 05). Four items included participation, preparation, communication ability and team spirit of experimental group students were significantly superior to those of the control group students (P<0. 05).?CONCLUSION:“One week with one case” teaching method with college-enterprise cooperation can improve comprehensive ability of students. It is an effective teaching method with the characteristics of the contact lens courses.

Objective To explore the related factors of fertilization failure after in-vitro fertilization and embryo transfer. Methods 150 patients were divided into total fertilization failure (TFF) group, low fertilization (LFR) group, and control (NFR) group according to fertilization rate. Semen was collected from the male pa-tients; the number, concentration, shape, and progressive motility of sperms were measured. Level of gACE was detected by Western blot. Logistic regression was used to explore the factors affecting fertilization rate. Results The fertilization rate and the concentration , progressive motility , and shape of sperms in were lower TFF group than in LFR group and NFR group (P < 0.05). Western blot proved that level of gACE group was higher in TFF than in LFR group and NFR group (P < 0.05). Logistic regression showed that the fertilization rate, the concen-tration , progressive motility , shape of sperms , and the level of gACE were all the independent risk factors for fertilization failure. Conclusions The concentration, progressive motility, and shape of sperms have impact on IVF. A lower expression of gACE in patients with lower fertilization rate can be used as a potential biomarker for predicting fertilization failure.

Objective By means of analyzing the antihypertensive use of hypertension patients of Guiyang in 2013 and impact factors for basic drug use,to evaluate the impacts of the essential medicines list in place in Guiyang to hypertension patients in communities in Guiyang.Methods 969 hypertension patients were surveyed with structured questionnaire of stratified random sampling at 6 community health centers in Guiyang city.Results Hypertension patients in communities averaged 1.4 types of antihypertensive,and the essential medicines used accounted for 39.8％of all the antihypertensive.The distribution differences of the ratio of essential medicines use are significant interms of age,gender,and household annual income.Use ratio of non-essential medicines of the 55～64 age group and 65～74 age group are 3.48 times and 0.47 times over that of the 75 and above age group.For hypertension patients of low income and medium income,their probable use of non-essential medicines is 2.05 and 2.87 times that of high income households.Conclusion As the use ratio of hypertension patients in Guiyang is relatively low,and the factors for it are age and household income,focused intervention is recommended for the 65～74 age group and low-income households,for the purpose of high use ratio of essential medicines of such people.

Objective To study the clinical significance of pulmonary membrane diffusing capacity(Dm) and pulmonary capillary blood volume(Vc) in patients with stable chronic obstructive pulmonary disease(COPD). Methods Spirometry was performed in 38 patients with stable COPD and 35 healthy individuals in resting condition.The changes of pulmonary parameters were obtained and compared between groups. Results Spirometry test revealed that the percent predicted forced expired volume in one second(FEV1),FEV1/forced volume capacity(FVC)and the percent predicted maximal ventilatory volume(MVV) were declined from stage Ⅰin patients with COPD in comparison with healthy individuals,while diffusing capacity for carbon monoxide of lung(DLCO),carbon monoxide diffusing capacity per liter of alveolar(DLCO/VA),Dm and Vc were declined from stage Ⅱ.Dm in patients with COPD of stageⅠwas sig-nificantly decreased compared with the controls,while Vc was increased compared with the controls(both P
