ABSTRACT
BACKGROUND: The rehabilitation treatment for acute myocardial infarction has started since 1980' s, but it has not been popularized yet in municipal hospitals due to limited conditions.OBJECTIVE: To probe into the possibility of 3-week rehabilitation intervention in patients with acute myocardial infarction implemented in municipal hospitals.DESIGN: Controlled retrospective analysis was designed.SETTING: Department of Cardiology of YingKou Center Hospital.PARTICIPANTS: Sixty cases of acute myocardial infarction were collected in Department of Cardiology of Center Hospital in Yingkou City in 1996 and they were taken as experimental group. Totally 58 cases of acute myocardial infarction hospitalized in 1986 were taken as the control. In experimental group, 44 cases were males and 16 cases females, aged varied from 34 to 79 years; of which, 45 cases were diagnosed as cardiac dysfunction and cardiac arrhythmia. The situation in the control was near basically to that in experimental group. During the intervention, in experimental group, 10 cases presented chest oppression, 3 cases were afraid to accept the intervention; but by monitoring and explanation, all of those accomplished the experiment.METHODS: In the control, only rational clinical management was given. In experimental group, at the same time of clinical management implemented,the rehabilitation treatment for 3 weeks was carried out for patients with acute myocardial infarction, aiming to earlier movement, earlier getting up, earlier discharge. The rehabilitation procedure stood by gradually increased exercise amount and individualization and it was adjusted according to age, situation of sickness and psychological state, etc. For instance, if the signs of over-endurance presented, the exercise would stop temporarily or the exercise intensity be reduced.MAIN OUTCOME MEASURES: Comparisons of exercise endurance, recovery time of exercise and hospitalizing time in 3 weeks of two groups.RESULTS: The patients in experimental group all accomplished 3-week rehabilitation intervention. In experimental group, the cases, in which, the exercise endurance was up to 5 to 6 equivalents 3 weeks after acute myocardial infarction, were more than the control (78%, 12%, P ＜ 0.05). The cases that were able to go up-down stairs were more than the control(83%, 7%, P＜ 0.05) . The cases hospitalized ＜ 3 weeks were more than the control (78%, 10%, P ＜0.05).CONCLUSION: It is practical and safe to carry on rehabilitation procedure for acute myocardial infarction in municipal hospital. Rehabilitation exercise at the early stage accelerates remarkably the recovery of acute myocardial infarction.
ABSTRACT
Indoor microbial contamination of the buildings and the related health impacts has been more and more concerned by the public.The indoor microbial contaminants contain bacteria,virus,fungus,dust mites,pollen and so on,and the source is diversity.Many studies at home and abroad have found that the microbial contaminants in different kinds of the buildings like the public places,schools,living rooms and so on are very popular,sometimes quite high level.Indoor microbial contamination can cause adverse impact on health of the exposed population,such as some infectious diseases,allergenic symptoms/diseases,even cancers.
ABSTRACT
Objective To know the microbial pollution in the indoor air of classrooms and dormitories in a university and analyze the possible impact factors.Methods In April and May,2007,the indoor air sampling was conducted and the total count of air microbe in indoors was determined in eight classrooms and twenty dormitories by the impacting method.Results According to the related national hygienic standard of China, the total count of air microbe in all classrooms was qualified, the total count of air microbe in the dormitories was all qualified, but it was higher in male's dormitories compared with female's.Conclusion In general, there was not obviously indoor microbial pollution in the investigated university.
