Objective To study the role of sodium nitroprusside in preventing pulmonary ische-mia-reperfusion injury and the possible mechanism. Methods Fourteen pigs were randomly divided into 2 groups: control group underwent controlled reperfusion with reperfusion solution (leukocyte-depleting blood modified buckberg perfusate = 4:1) for 10 min at lower pressure of 18 mm Hg and 37℃? 1℃ before removing the pulmonary artery clamp; experimental group were subjected to controlled reperfusion with reperfusion solution before removing the pulmonary artery clamp, followed by infusion of sodium nitroprusside (10?g?kg-1?min 1 for 10 min) via pulmonary artery. Blood oxygen pressure, pulmonary vascular resistance, pulmonary compliance and the changes in pulmonary oxygen-ation function were assessed 0. 5, 1 and 2 h later. After the trail, the contents of water, NO and MDA in pulmonary tissues were measured. Results In the experimental group, left lung oxygenation function and pulmonary compliance was significantly better (P

Objective To investigate the effect of the use of audio and video feedback on the rehabilitation of patients with ankylosing spondylitis (AS). Methods 60 AS patients were divided into two parts (32 in the experimental group and 28 in the control group) by random number table method, and two groups of patients were treated with the same drug treatment. Patients in the control group were instructed by oral instruction, in the experimental group, the use of audio and video feedback teaching guide patients family exercise, compared with the two groups of patients with four months of follow-up, family exercise compliance, joint function and quality of life, and other indicators. Results Four months after the intervention, the experimental group patients family exercise compliance was better than 84%(27/32), higher than the control group of 36% (10/28), the difference was statistically significant (χ2=9.238, P < 0.01). Patients in the experimental group in four months after the intervention, the health questionnaire to investigate the physiological function, role limitation due to physical problems, body pain, general health, vitality, social function, role limitation due to emotional problems, mental health eight dimension scores respectively were (72.7±8.4), (81.5±9.5), (57.2±8.4), (65.5±8.4), (62.9±7.2), (78.4±7.4), (67.3±6.2), (77.2±7.6) points while in the control group were (60.8±9.1), (72.1±9.6), (50.3±9.4), (60.8±7.0), (58.2±9.1), (74.4±8.7), (60.2±7.2), (74.3±7.4) points, the difference between the two groups had statistical significance (t=1.493-5.266, P < 0.05 or 0.01). Four months after the intervention, the scores of Bath Ankylosing Spondylitis Functional Index (BASFI) of patients with AS in the experimental group were (1.1± 0.8), (1.7±0.2), (1.8±1.3), (1.6±1.0), (3.1±2.1), (1.0±0.6), (1.9±1.6), (3.8±2.5), (2.6±1.7), (2.7±1.6) points, while (3.8±1.6), (2.8±1.5),(2.6±1.5)、(2.8±1.2),(4.4±2.2),(2.2±1.0),(3.3±1.6),(6.5±2.5),(5.6±2.6), (4.3 ± 1.5)control group, the two groups the difference was statistically significant (t=0.282-8.427, P<0.05). Conclusions Application of audio and video feedback teaching in patients with AS rehabilitation guidance, help patients to master the family training methods, improve the joint function of patients, improve the quality of life.

Objective To evaluate the effect of the standardized training program for resident physicians in Ruijin Hospital,and analyse the problems so as to provide reference to improve the training.Methods Questionnaire surveys were conducted among 113 resident physicians,31 teachers and 43 head nurses in Rujin Hospital by using the simple random sampling and 300.The data was analysed by Kirkpatrick's model in four layers including reaction layer,learning layer,behaviors layer and results layer.Data of reation layer was analysed by ANOVA and data of behaviors layer was compared by paired t-test.Results Reaction layer:the resident physicians' overall satisfaction score for the training is 3.45.Learning layer:all resident doctors participating in the training passed all the exams organised by the hospital.Behaviors layer:Residents made a great progress in many aspects after the standardized training program,and the difference was statistically significant (P＜0.01) according to the analysis of all questionnaires written by residents,clinical teachers and head nurses.Results layer:both the patient complaint rate and the accident rate of the 113 resident physicians was 0 while they all passed the National Medical Licensing Examination and the employment rate was 100％.Conclusions the standardized training program for resident physicians in Ruijin Hospital gets fairly good effect.Resident doctors' quality and ability in many aspects are improved and the overall satisfaction for the training is high,but in salary,benefits and sense of belonging to the hospital,the satisfaction is relatively low.
