ObjectiveTo discuss the relationship between serum homocysteine (Hcy) level and severity of acute coronary syndrome(ACS) through measuring the level of serum Hey in the patients with ACS.Methods95 patients who were diagnosed ACS were divided into two groups:40 cases of unstable angina(UA) and 55 cases of a cute myocardial infarction(AMI).30 individuals were chosen as normal control(NC).In addition,according to the results of coronary angiography,the same 95 patients were further divided into three subgroups which were single-vessel disease( 28cases),double-vessel disease ( 36cases ) and multi-vessel disease ( 31 cases ).Level of serum Hcy was measured in all groups.ResultsSerum Hcy level of ACS patients was significantly higher than NC group( P ＜ 0.01 ).The level of serum Hcy in AMI group was significantly higher than that in UA group( P ＜ 0.05 ).The Hcy level in the multi-vessel disease group,double-vessel disease group and single-vessel disease group were increased in turn,and the difference of pairwise comparison was statistically significant ( P ＜ 0.05 ).ConclusionThe serum Hcy level has rela tionship with the severity of coronary lesions and is directly proportional to the number of coronary artery lesions.The result suggests that the level of serum Hcy maybe play an important role in the prevention,diagnosis,treatment and monitoring of ACS.

Objective To investigate the effect of intensive nursing intervention on the secondary infection in chemotherapy of elderly patients with lung cancer.Methods 168 cases of elderly lung cancer patients whose neutrophil ≤ 1.0×109/L during chemotherapy were randomly divided into two groups,namely,the intensive care group and the control group,with 84 cases in each group.The control group was given routine nursing of infection prevention,while the intensive care group was given intensified nursing for infection prevention.A contrastive analysis was conducted in terms of the incidence,clinical characteristics and the duration of antibiotic treatment of the two groups of patients with secondary infection.Results The secondary infection rate of the intensive care group was lower than that of the control group during chemotherapy.What's more,the duration of fever and treatment of the intensive care group was shorter than that of the control group,hence the patients were safe during infection period.The difference was statistically significant.Conclusions Strengthening the nursing intervention can reduce the incidence rate of secondary infection in aged patients with lung cancer,increase the tolerance of patients to chemotherapy and ensure the successful completion of the chemotherapy cycle,prolong the life span of the patients with an improved quality of life.

Through the analysis of questionnaire about medical ethics cases teaching,we acquire the recognition states of medical students about cases teaching of medical ethics,find out the problems in teaching processes and provide reality basis for carrying out cases teaching in medical ethics education purposedly and effectively.

On this paper,the author explored the experimental teaching system of medical physics under the guidance of giving the prominence to the characteristics of medical physics experiment,and strengthening the improvement of medical students’com-prehensive quality.The purpose of this paper is to make good use of the updated course design and advanced teaching methods,get the physics experiment to form an independent and integrated system based on the requirements of experiment example center materials proposed by National Education Committee.

By comparing the correlated evaluation index between Researches in Medical Education and Chinaese Journal of Medical Education,the author analyzed their differnces to promote one another and raise the quality of running both journals.

Developing and promoting college students' employment guidance work,setting up the right career ideal and professional concept,helping students make a reasonable career choice in the fierce competition have become the most prior work in the university. The essay mainly studies the present situation of college career guidance and the existing problems,discusses how to improve the employment guidance work in combination with the practice work in the new situation.

Objective:To analyze the serum levels of 25OHD 3 in children.Methods:489 children who visited the Children's Hospital of Chongqing University Medical Sciences during 1994 to 2001 were included in the analysis.Serum level of 25OHD 3 was measured for each child by reversed-phase HPLC method,which was developed in our laboratory in early 1990s.Results:Of the 489 children, boys 287(58.69%) and girls 202(41.31%).30.67(150/489) children had serum level of 25OHD 3 above the normal range in this laboratory.23.31%(114/489) children had a serum 25OHD 3 below the normal range.The majority came from the Department of Primary Child Care of this hospital.77.86%(102/131) children clinically diagnosed as hypervitamin D were proved by our 25OHD 3 measurement,while only 37.29%(44/118) children clinically diagnosed as vitamin D deficiency had their serum 25OHD 3 below the normal range.In bone fracture patients,10.34%(3/29) children were found to be at lower level of serum 25OHD 3.Conclusion:Pediatricians should realize the possibility of herpervitamin D caused by incorrect treatment of rickets.The diagnosis of rickets,i.e.vitamin D deficiency,could not be just based on its clinical manifestations.25OHD 3 measured by HPLC is important for making correct diagnosis.
