[Objective] To analyse seminal fluid quality of seamen with unsterility,discuss the concerned environmental influencing factors.[Method] Take 128 seamen as research group,100 drivers as control;apply the Qinghua Tongfang Auto Analytic Instrument to routinly test the seminal fluid.[Result] For the seamen with unsterility,the important indexes of spermatozoon concentration,activity rate and level-a ratio were much reduced(P

Objective:To analyze the usage of anti-hypertensive drugs in our hospital,and provide a reference for clinical rational drug use.Method:With the consumption sort and DDDs analysis,the consumption of anti-hypertensive drugs used in 2006-2008 was analyzed.Result:The consumption of anti-hypertensive drugs in our hospital increased every year,and the consumption of the angiotensinⅡreceptor blockers(ARB),calcium channel blockers(CCB),angiotensin-converting enzyme inhibitor(ACEI) in three years were the top three of the total drug consumptions.Conclusion:The use of anti-hypertensive drugs was basically rational in our hospital and matched the domestic usage of anti-hypertensive drugs.

BACKGROUND: Insulin resistance may be a risk factor for hypertension,but the relationship between insulin resistance and hypertension are quite different from different race or nationalities. OBJECTIVE: To analyze the relationship between insulin resistance and hypertension in Chinese Mongolian population.DESIGN: Prevalent investigation.SETTING: Staff Room of Epidemiology, Public Health College of Harbin Medical University. PARTICIPANTS: Totally 232 patients with primary hypertension and persons with normal blood pressure, aged from 30-60 years from Kezuohouqi of Tongliao city in June 2001 based on the prevalent survey, and they all Mongoloid population. Examination was performed and blood pressure was measured. They were involved in this investigation after signing the consent. Other cardiovascular disease patients were excluded.METHODS: A total of 115 patients with primary hypertension and 117normotensives were selected with cluster sampling method. Height, body mass, waistline, hip line and waist-to hip ratio (WHR), I.e. Waist line/ hip line were standardization method. Body mass index (BMI) ＜ 24 kg/m2 or waist-to-hip ratio (WHR) ＜ 0.9, body mass or somatotype was partial to normal. Blood glucose was detected with glucose meter. Radio-immunoassay (RIA) were utilized to measure insulin and C-peptide. Degree of insulin resistance was determined by means of insulin sensitivity index (ISI), ISI =-ln [glucose (mmol/L) × insulin (Mu/L)]. After considering the effect of BMI and WHR as well as the stratification of BMI (≥24 kg/m2 and ＜ 24 kg/m2) and WHR (≥ 0.9 and ＜ 0.9), statistical analysis was performed. MAIN OUTCOME MEASURES: ISI of the investigational subjects of the two groups. RESULTS: Totally 232 included investigational subjects were involved in the result analysis, without drop out. ①Comparison of ISI of the investigational subjects of the two groups: The ISI of the hypertension group was slightly lower than that of the normotensive group, but the difference was not significant [-3.56±0.27,-3.50±0.20(P ＞ 0.05)]. ②Comparison of ISI of the investigational subjects of the two groups after delamination according to BMI and WHR: When the BMI was less than 24, the ISI in the hypertension group was lower distinctly than that in the normotensive group [-3.56+0.27,-3.48±0.17(F=5.037, P ＜ 0.05)]. When the WHR was less than 0.9, the ISI of the hypertension group was lower dramatically than that in the normotensive group [-3.57+0.27,-3.49+0.20(F=4.537, P ＜ 0.05 )].CONCLUSION: The insulin resistance may be related to primary hypertension in non-obese Chinese Mongolian population.
