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.

Objective: To investigate the expression of pituitary tumor transforming gene (PTTG) and basic fibroblast growth factor (bFGF) in oral squamous cell carcinoma and their relation with each other, as well as the relationship of their expression with clinical-pathological indexes. Methods: The expression of PTTG and bFGF were examined among 55 oral squamous cell carcinoma tissues and 10 normal oral mucosal tissues by the streptavidin-biotinperoxidase (S-P) method. Results:The positive rate of PTTG and bFGF was 78.2% and 67.3% respectively in oral squamous cell carcinoma. The positive rate and grade of PTTG and bFGF were significantly higher than that in the normal mucosa tissues (P

The Apolipoprotein E(APOE)gene plays important roles in the pathogenesis of the Alzheimer disease(AD).It is clear that APOE gene is closely related with dementia in the elderly.In recent years,extensive researches regarding the relationship between APOE gene polymorphism and AD has been conducted in both health population and patients with AD using molecular biology technique.This paper reviewed the progress in this field for sharing some fundamental information on the research in AD.

Actovegin is a drug,which can improve cellular energy metabolism,especially glycometabolism.It has an insulin-like effect,such as increasing the uptake of glucose and activating glucose metabolic enzyme.In addition,it can inhibit the production of lactic acid.Actovegin was mainly applied to the treatment of Alzheimer disease initially,but now it is indicated more and more.

Objective To discuss mammographic findings and pathologic foundation of the fat necrosis of the breast and to improve the imaging diagnosis of the fat necrosis of the breast. Methods The mammographic findings of 91 cases with pathologically proved breast fat necrosis were retrospectively analyzed, of which 2 cases were bilateral breast fat necrosis, and a comparison with pathological results was made. Results The mammographic findings included (1)No abnomal mammographic findings (n=14, 15.4%);(2) Single and multiple lipid-cysts (n=6, 6.6%);(3) Masses (n=20, 22.0%), of which 1 case was bilateral breast mass;(4) Nodules (n=13, 14.3%);(5) Focal opacities like stars or pieces in the subcutaneous fat layer (n=28, 30.8%), of which 1 case was bilateral breast lesion;(6) Faint reticular opacity in the subcutaneous fat layer (n=5, 5.5%);(7) Structure distortion (n=5, 5.5%). The location of the liesions:(1) 55 lesions located in fat layer;(2) 13 lesions standed out to the fat layer or located the boundary of the fat layer and breast parenchyma. When routine mammography demonstrated the disease located the boundary of the fat layer and breast parenchyma, there will be helpful with tangent location mammography to show the disease in the subcutaneous fat layer;(3) 9 lesions located in the breast parenchyma;(4) 14 lesions did not find abnormity in the mammography. The pathologic appearance (1) A lipid cyst is the characteristic mammographic finding in the early stage of the lesion;(2) Asymmetry density masses or nodules in the subcutaneous fat layer is the characteristic mammographic finding in the metaphase stage of the lesion, which hinted necrotic fatty tissue gradually be replaced by fibrous tissue;(3) Focal opacities like stars and irregular reticulation findings in the subcutaneous fat layer or superficial layer adenoid tissues are the characteristic mammographic findings in the later stage of the lesion, which hinted that necrotic fatty tissue was licked up, circumference remained some fibrous tissue.The mammographic findings of the different pathological stages often appear in the same time. Conclusion The mammographic findings of fat necrosis of breast was different in its different stage. The mammography is very helpful for making the diagnosis of breast fat necrosis.
