Objective: To explore the relationship between insulin sensitivity index （ISI）and extent of coronary atherosclerosis in Uygur and Han nationality patients. Methods: A total of 125 patients with coronary heart disease were enrolled, including 59 Uygur nationality patients and 66 Han nationality patients. There were 42 cases with stable angina pectoris, 52 cases with unstable angina pectoris, 31 cases with old myocardial infarction, 53 cases with type 2 diabetes and 35 cases with hypertension. Relevant medical history of patients [age, body mass index (BMI) etc.] was collected and laboratory examination （blood lipid, fasting blood glucose, fasting insulin etc.）were performed, and extent of coronary atherosclerosis was evaluated by coronary angiography in all patients. ISI was calculated and its relationship with extent of coronary atherosclerosis was analyzed. Results: In both nationality patients, ISI was negatively correlated with extent of coronary atherosclerosis (Han nationality: r=-0.71, P=0.03, Uygur nationality: r=-0.52, P=0.04). ISI was negatively correlated with BMI, glycosylated hemoglobin (HbA1c) and low density lipoprotein –cholesterol (LDL-C) (r=-0.45, -0.68, -0.55, P<0.05 all) in Han nationality patients; ISI was positively correlated with high density lipoprotein–cholesterol (HDL-C, r=0.67, P<0.01), and negatively correlated with HbA1c, LDL and lipoprotein a (r=-0.47, -0.35, -0.42, P<0.05) in Uygur nationality patients. Conclusion: Insulin resistance participates and promotes formation and development of coronary atherosclerotic plaques. Controlling weight, blood glucose and LDL-C levels etc. can decrease insulin resistance and prevent occurrence and development of coronary heart disease.

Objective:To observe the short-term therapeutic effect and safety of amlodipine combined terazosin on middle and old aged male patients with essential hypertension (EH).Methods:A total of 64 middle and old aged male EH patients treated in our hospital from Jan 2011 to Feb 2012 were enrolled.They were randomly and equally divided into amlodipine group and combined therapy group (received amlodipine combined terazosin treatment).Re-sults:Total effective rate of combined therapy group (93.75%)was significantly higher than that of amlodipine group (65.63%),P =0.028;there were significant reductions in levels of systolic blood pressure (SBP),diastolic blood pressure (DBP),total cholesterol (TC),triglyceride (TG)and fasting plasma glucose (FPG)in both groups after treatment (P <0.05~<0.01),compared with amlodipine group,there were more significant reductions in these indexes [SBP:(138.55±7.96)mmHg vs.(110.65±7.28)mmHg,DBP:(93.35±5.86)mmHg vs.(80.11 ±5.93)mmHg,TC:(5.67±0.76)mmol/L vs.(4.22±0.63)mmol/L,TG:(2.67±0.86)mmol/L vs.(2.01± 0.75)mmol/L,FBG: (5.69±0.86)mmol/L vs.(4.31±0.58)mmol/L]in combined therapy group,P <0.05 all;incidence rate of adverse reactions in combined therapy group (6.25%)was significantly lower than that of am-lodipine group (18.75%),P <0.05. Conclusion:Amlodipine combined terazosin possesses more therapeutic effect in middle and old aged male patients with essential hypertension.It can effectively reduce systolic and diastolic blood pressure;the adverse reactions are fewer,so it's worth extending in clinic.

Objective: To determine the national norm of Chinese questionnaire of quality of life in Chinese patients with cardiovascular diseases (CQQC) according patients with hypertension, coronary artery disease（CAD）, and congestive heart failure（CHF）and to analyze the influence factors. Methods: The quality of life was estimated by CQQC to evaluate 7937 persons normal and with cardiovascular diseases（contain with hypertension, CAD, and CHF ） in 28 hospitals of 19 cities across China. The data were compared in gender, age, exercise, psychologic condition, education, number of family member and medical cost. Results: 1、The mean scores（national norms）of normal persons were （95.74±23.21）; 2、The scores of hypertension patients were （73.75±23.62）, the scores of hypertension stage 3 group （69.06±21.78）were least compared with other stages（P<0.01）; 3、The scores of CAD patients were（64.67±20.59）, the scores of unstable angina group（55.37±18.62）were least compared with other types in CAD patients（P<0.01）; 4、The scores of CHF patients were （40.36±17.24）, it was least compared with those of hypertension and CAD patients （P<0.01）; 5、Influence factor: （1）Sex, age: The mean scores were （71.41±27.8）for 7937 persons, the scores of male persons were significantly higher than those of female (P=0.000). In normal persons, along with age increased, the scores decreased （P<0.05） ; except ≥70 ages group, the scores of male persons were higher than those of female（P<0.05） ; （2）Exercise: The scores of patients participating exercise were significantly higher than those of no participating exercise [（72.64±21.87）vs.（66.91±23.13）, P=0.000]; （3）Psychological condition: The scores of patients with healthy psychological condition were significantly higher than those of with psychologic disorder [（70.13±25.66）vs.（68.91±20.44）, P=0.001]; （4）Other: patients with better education, more than 1 family members and medical insurance or public expense had more scores (P<0.05～0.001). Conclusions： The sample size is large and the datum is reliable for Chinese questionnaire of quality of life in Chinese patients with cardiovascular diseases. It can reflect influence of age, sex, exercise, psychologic condition, family, education background, medical condition and disease, its item is brief, clear, and operation is easy, so it may well be spread.
