Objective To explore the clinical application of anticoagulation therapy for patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods 55 patients with AECOPD were selected and divided into control group(24 cases) and treatment group(31 cases).Oxygen treatment,anti-infection treatment were applied to the patients of the control group.Treatment group was given anticoagulation treatment with heparin at the base treatment of the control group.The treatment efficacy,pulmonary functions,coagulation functions and inflammatory factors were tested and compared.Results There were no significant differences between two groups of total treatment efficacy(80.65％ vs 79.17％,x2 =1.304,P ＞0.05) ;PaCO2 decreased,pH and PaO2 increased significantly after treatments in the two groups(all P ＜ 0.05),which was more significantly in the treatment group (all P ＜0.05) ;FVC,FEV1 and FEV1/ FVC％ increased significantly after treatments in the two groups(all P ＜ 0.05),more significantly in the treatment group (all P ＜ 0.05) ; APTT,PT were prolonged,the level of DD and PAD decreased significantly after treatments in the two groups(all P ＜ 0.05),which was more significantly in the treatment group(all P ＜ 0.05) ;The level of IL-6,IL-10 and hs-CRP decreased significantly in all patients(all P ＜ 0.05),IL-6and hs-CRP were more significantly in the treatment group (all P ＜ 0.05),but the level of IL-10 of the treatment group was higher than that of the control group (P ＜ 0.05).Conclusion Pulmonary functions,Blood-gas indexes could be improved,inflammatory balance and coagulation status could be maintained by anti-coagulation treatment in patients with AECOPD.

Objective To investigate effects of sevoflurane and propofol on hemodynamic changes in patients undergoing cardiac double valve replacement.Methods Totally 80 patients admitted with rheumatic heart disease were divided into sevoflurane group and propofol groups.The anesthetic drugs on hemodynamics,myocardial function and renal function were compared.Results There were statistically significant in CIL concentration,stroke volume index (SVI)and left ventricular -stroke work index (LVSWI)levels between the two groups at the same time points (F =2.467,2.4783,2.553,P =0.032,0.032,0.021).The levels of MAP,HR,PAWP,CIL,SVI and LVSWITBIL between the two groups were statistically significant at different time points (F =2.597,2.468,2.523,2.589,2.532, 2.556,P =0.032,0.021,0.030,0.021,0.024,0.023),and difference at the same group at different time points (F =2.597,2.468,2.523,2.497,2.479,2.538,P =0.032,0.021,0.030,0.034,0.034,0.038).No obvious liver and renal function damage was found during the surgery in the two groups.Conclusion Anesthesia induction of sevoflurane and propofol for patients undergoing cardiac double valve replacement has similar effects on the hemody-namics and cardiac function,without obvious damage to liver and renal function.

Objective To explore the teaching effect of cooperative learning approach in the training class of basic nursing operation techniques for male students. Methods A total of 82 male nursing students who were admitted into college in 2013 with a 3-year study program were divided into two groups based on mechanical sampling method, 42 students in the experimental group were trained with cooperative learning approach, while 40 students in the control group were trained with traditional teaching method. At the end of the semester, surveys were conducted and the results of students′operative skill were analyzed. Results The result of operative skills evaluation in the experiment group was 88.0 ± 6.9while that in the control group was 79.0 ± 9.2. The comparative difference between the two groups had statistical significance(t = 4.392,P<0.01). The qualified rate in the experiment group was 95.23%(40/42)while that in the control group was 70.00%(28/40).The comparative difference between the two groups had statistical significance(χ2=9.118,P<0.01). Conclusions Cooperative learning approach can improve the teaching effect of nursing operative skills for male nursing students. Thus it is an effective teaching method that deserves promotion and application in the practice teaching of Basic Nursing Techniques.

To introduce the academic thoughts of traditional Chinese medicine(TCM)master GUO Zi-guang based on the analysis of clinical cases.His main academic thoughts are:①He proposes the theory of six meridians and their differentiation in the diagnosis and treatment of typhoid.The six meridians are bases for the treatment of all diseases,and their differentiation provides a fundamental principle for the differentiation of diseases.②He uses the method of combining the disease and syndrome in diagnosis and treatment,which widens the horizon of traditional differentiation and diagnosis in TCM and avoids the absence of syndrome in the practice of differentiation.In this way,the therapeutic effects of Chinese medicine can be guaranteed so as to meet the needs of medical and social development.③He emphasizes that it is fundamental to improve the therapeutic effects of TCM for its development.The approach is to combine disease and syndrome in diagnosis and treatment,and the way is to apply different methods in disease treatment.
