BACKGROUND: In treatment of traditional acute myocardial infarction,patients were required to lie on the bed resting for 1-4 weeks. Recently research showed that early rehabilitation exercise in myocardial infarction patients could ameliorate the reservation of cardio function, increase exercise tolerance, augment myocardial hemoperfusion, decrease myocardial ischemia and reduce the anxious and depressive emotion.OBJECTIVE: To observe the influence of early rehabilitation movement on activity of daily living, duration of hospital stay, mean hospitalized cost,incidence rate of arrhythmia and recurrence rate of myocardial infarction in two years.DESIGN: Non-randomized concurrent control analysis.SETTING: Beijing Tiantan Hospital.PARTICIPANTS: Totally 80 patients with acute myocardial infarction,who were hospitalized at Department of Circulation, Beijing Tiantan Hospital from August 2002 to October 2003, were enrolled. They were all at most 70 years old with stable pathogenetic condition. Left ventricular ejection fraction (LVEF) was over 35%. They were not combined with severe hypertension, severe pulmonary disease, nerve and disease of locomotor system.METHODS: The selected cases based on patients' will were assigned into two groups (n=40), ①early rehabilitation group: They were treated with routine drugs, absolute bed rest for 24 hours. At day 2 the head stock was rose about 30°to do passive exercise of extremity joint. At days 3-5, the patients sat on the bed, 3 times per day. At days 6-7,the patients stood at bedside, 3 times per day. At days 8-9, the patients moved joints of extremities at bedside and walked slowly in room. At days 10-14, the patients exercised walking. If there were angina pectoris attacks, serious cardiac arrhythmias or dyspneic respiration, etc., the movement should be suspended or the exercise intensity came back to that in the former stage. ②Absolute bed rest group: The patients were absolute bed rest, and only treated with routine drug without any rehabilitation training.MAIN OUTCOME MEASURES: Barthel index (full mark was 100 points, and ＜ 60 points represented unable self-care) was used to assess activity of daily living of patients. Mean duration of hospital stay, mean hospitalized cost, incidence rate of arrhythmia and recurrence rate of my ocardial infarction in two years were compared between the two groups.RESULTS: A total of 80 patients that conducted the therapy and follow up were involved in the result analysis. ①Mean duration of hospital stay and mean hospitalized cost in the early rehabilitation group were less than those in the absolute bed rest group (17.1 days vs 24.5 days; 9 021.23 yuan vs 12 383.45 yuan; P ＜ 0.05). ②Barthel index: There was insignificant difference before treatment between the two groups. It was significantly higher in the early rehabilitation group than that in the absolute bed rest group before discharge (81.43±13.57,70.68±11.48,P ＜ 0.05). ③Six and seven patients had the onset of arrhythmia in the early rehabilitation group and the absolute bed rest group, respectively. ④Follow-up observation was performed for two years. The recurrence rate of myocardial infarction in the early rehabilitation group (5% ,2/40) was obviously lower than that in the absolute bed rest group (22 %,9/40).CONCLUSION: The early rehabilitation training is of benefit to elevate activity of daily living of myocardial infarction patients, reduce mean duration of hospital stay and mean hospitalized cost and decrease recurrence rate.

Aim To establish an animal model of inflammatory pleural adhesion and to investigate the role of low-molecular-weight heparin(LMWH) in preventing encapsulation of pleural effusion.Methods Thirty New-Zealand rabbits were randomly divided into three groups:the model and the treatment group received injection of tetracycline(35 mg?kg~(-1)) in the right chest cavity,the control animals received injection of normal saline.LMWH (55 U?kg~(-1)) was injected into the right chest cavity of rabbits in the treatment group.The animals were killed on 14 d.Result In the model group,pleural effusion appeared at 2 h and reached maximum within 2～3 days.In the effusion,leukocytes accumulated and procoagulant activity increased at the same time.Fibrosis and pleural adhesion,encapsulation appeared on the fourteenth day.In the treatment group pleural effusion and procoagulant activity were reduced.No pleural adhesion was observed.Conclusion Tetracycline was successfully used to establish an animal model of pleural adhesion in rabbits.LMWH was effective in reducing pleural effusion and preventing pleural fibrosis and encapsulation.

Protein post-translational modifications are important ways to regulate protein function and cell behavior, and oxidative stress directly influences protein post-translational modifications. P53 protein has various post-translational modifications, which can be quickly regulated under stress conditions to activate a series of downstream target genes and facilitate the p53 function diversity. The effects of oxidative stress on p53 post-translational modifications of phosphorylation, ubiquitination, sumoylation, acetylation and methylation are introduced in this paper.

BACKGROUND:Vascular endothelial growth factor(VEGF)can promote vascular endothelial regeneration,inhibit thrombosis,and attenuate neonatal intimal thickness and luminal stenosis degree.OBJECTIVE:The present study established atherosclerosis models in rabbits and observed the effects of local transfection of VEGF gene on restenosis after angioplasty.DESIGN,TIME AND SETTING:A randomized controlled animal experiment was performed at the Laboratory of Microorganism,Tongji Medical College,Huazhong University of Science and Technology between November 2004 and December 2006.MATERIALS:Rabbits were daily raised with high-fat diet to create atherosclerosis models.Twenty successful rabbit models were randomly and evenly divided into a control group and a gene treatment group.METHODS:The DcNDA 3.0 recombinant human VEGF165(hVEGF 165)was trimsferred to the ventral aorta through the use of Foley's catheters.and the pcDNA3.0 was transfefred in the controls.MAIN OUTCOME MEASURES:At 1,2,and 4 weeks after surgery,luminal area of left renal artery opening was measured by MRI.At 2 and 4 weeks after surgery,the ratio for intimal to medial area was obtained through the use of HMIAS-2000 high definition color medical image analysis software.Simultaneously,vascular endothelial cell regeneration was observed by immunohistochemistry of factor Ⅷ related antigen.RESULTS:The pcDNA3.0/hVEGF 165 could be successfully transferred through the use of Foley's catheters.At 2 and 4 weeks after surgery,luminal area was larger in the gene treatment group than in the control group(P<0.01);simultaneously, the ratio of intimal to medial area was significantly smaller in the gene treatment group than in the control group(P<0.05).In the gene treatment group,expanded vascular endothelial cell regeneration was accomplished at 2 weeks after surgery,while in the control group,it took 4 weeks.CONCLUSION:pcDNA3.0/hVEGF 165 gene transduction can promote local vascular endotllelialization and apparently attenuate restenosis degree and intiaml thickening.

Objective To analyze right ventrieular diastolic dysfunction in essential hypertension by quantitative tissue velocity imaging(QTVI). Methods Twenty normotensives and forty-five hypertensives underwent standard Doppler echocardiography and QTVI of right ventricular lateral tricuspid annulus. By QTVI,diastolic measurements were obtained. According to WHO standard, the patients with hypertension were classified into three groups, grade Ⅰ (group Ⅰ) 15 cases, grade Ⅱ(group Ⅱ) 15 cases, grade Ⅲ (group Ⅲ) 15 cases. Results Pulsed Doppler eehocardiography showed impaired Doppler diastolic indexes in hypertensives, without changes among the eases groups. In all hypertension groups, QTVI showed reduction of right ventricular Ea, increase of Aa and Ea/Aa<1 comparison with controls. IVRT of Ⅱ, Ⅲgroups was longer than normal. Conclusions Right ventricular diastolic function with essential hypertension decreased according to the degree of staging. QTVI has a greater predictive value than conventional imaging, and is useful for evaluating right ventricular function in patients with essential hypertension.

Objective To explore the factors influencing the patients' treatment compliance infected with chronic hepatitis B virus, and provide some useful advices to improve patients compliance. Methods Data were collected through deep interviews with 9 patients and analyzed using a phenomenological hermeneutic method. Results Using generic analysis, the factors influencing patients' compliance fell in-to three themes: (1) The enforceability of the doctor's advice; (2)The factors of the patients their own, in-cluding the disease-related knowledge, the realization of how harmful the disease is, and past behavior habits; (3)The social factors, including economic situation, pressure of life, family care, and the supervision and guidance of health care workers. Conclusions In order to make the patients consciously adopt the doctor's advice, health workers should pay more attention to strengthen the enforceability of the doctor's ad-vice and health education, and focus on the impact of cognitive, psychological and social factors on pa-tients' compliance.
