Ties essay discusses the law problems about procreation right in single women in order to improve the law and protect peoples rights.

The promulgation of regulations of coping with public health affairs outbreak offers the powerful legal protection. In order to enhance the consciousness implementary, we must go along with futher discussion of ethical principle in the regulations. By doing this, we expect to enhance the responsibility, collaboration and dedication consciousness of people, then to prevent and control the occurrences of public health affairs outbreak effectively.

With the development of medicine and the raising of people' s health sciousness, the structure of harmoaious medicine ethic views will be more important. It will have great directive meaning on the innovation development of medicine ethincs system, have fatal practical meaning on protesting people's livesand health, and also have far- reaching meaning on the persistent development of health career.

The proposal of the view of scientific development is a new opportunity for the development of the hygiene industry,and plays an important part in the prevention and cure of AIDS.Therefore,during the prevention and cure of AIDS,we should make people the center,coordinate comprehensively,and promote social harmony,to strengthen the ba?sis of the prevention and cure of AIDS.

AIM:To evaluate the effects of atorvastatin on nitric oxide(NO),endothelin-1(ET-1)and myocardial no-reflow in a rabbit model of acute myocardial infarction and reperfusion(AMI/R). METHODS:Twenty-four rabbits were randomized into 3 groups:8 in AMI/R group,8 in atorvastatin-treated group(5 mg·kg~(-1)·d~(-1))and 8 in sham-operated group. Animals in the former two groups were subjected to 60 min of coronary occlusion followed by 120 min of reperfusion. Data on haemodynamics were collected. NO in blood sample,and in normal,and in infarcted reflow and no-reflow myocardium were evaluated respectively by nitrate reductase method. The levels of ET-1 in blood sample,and in normal,infarcted reflow and no-reflow myocardium were determined by radioimmunoassay. RESULTS:(1)Compared to the baselines,the heart rate(HR),systolic blood pressure(SBP),diastolic blood pressure(DBP),left ventricular systolic pressure(LVSP),maximal rate of increase and decline in left ventricular pressure(±dp/dt_(max))and cardiac output(CO)in AMI/R and atorvastatin-treated groups were significantly declined,whereas left ventricular end-diastolic pressure(LVEDP)was increased after 60 min of coronary occlusion and 120 min of reperfusion(P<0.05 or P<0.01). However,in atorvastatin-treated group,LVSP,LVEDP,±dp/dt_(max) and CO at the time point of 120 min of reperfusion recovered more significantly than those at the time point of 60 min of coronary occlusion(P<0.01),which was more significant than those in AMI/R group(P<0.05 or P<0.01). Compared to AMI/R group,the SBP and DBP were significantly heigher in atorvastatin-treated group(P<0.01).(2)In atorvastatin-treated group,the levels of ET-1 in blood sample were significantly lower than those in AMI/R group(P<0.01),and the levels of NO were significantly higher(P<0.01). Moreover,the levels of NO or ET-1 in infarcted reflow myocardium were significantly lower than that in AMI/R group(P<0.05 or P<0.01).(3)Atorvastatin could ameliorate myocardial function. CONCLUSION:Atorvastatin is effective in increasing NO and reducing ET-1 in blood plasma and local myocardium,and in protection of endothelial cells. Atorvastatin also has a beneficial effect on improving left ventricular function during acute myocardial infarction and reperfusion in rabbits.

A questionnaire is carried out in order to understand the status quo of life view among medical students in our college.The analysis of the data shows there are deviations in treating death,significance of life,life value,etc.Therefore,we conclude that it's imminent to strengthen the life-education for medical students.

The promulgation of regulations of coping with public health affairs outbreak bring the prevention and cure of atypicalpneumonia into a legal system, and it has an important meaning of overcoming the atypicalpneumonia. In order to cope with all kinds of public health affairs outbreak more effectively, we must perfect the public health legal system, establish scientific system of meeting emergency, strengthen the popularization and education of legal knowledge, and enhance the whole social consciousness of prevention epidemic diseases by law.

Animals in the former two groups were subjected to 60 min of coronary occlusion followed by 120 min of reperfusion. Data on haemodynamics were collected.

RESULTS:(1)Compared to the baselines,the heart rate(HR),systolic blood pressure(SBP),diastolic blood pressure(DBP),left ventricular systolic pressure(LVSP),maximal rate of increase and decline in left ventricular pressure(?dp/dtmax)and cardiac output(CO)in AMI/R and atorvastatin-treated groups were significantly declined,whereas left ventricular end-diastolic pressure(LVEDP)was increased after 60 min of coronary occlusion and 120 min of reperfusion(P

According to the characteristics of general surgery class teaching,methods and experiences of the application of associative approach to general surgery class teaching were analyzed,such as word,picture,contrast,comprehensive,analogical and association,which is advantageous to the improvement of class teaching methods,effects and students' study interests and ideation.
