The von willebrand factor (vWF) and angiotensin converting enzyme(ACE) were measured in asthmatic patients in stages of attack and remission, using ELISA and ultraviolet methods. The results showed that the vWF and ACE were (72.1 ? 58.3)%, and 22.9 ? 6.9U in the stage of attack, and (68.8 ? 42.1)% and 23.2? 7.9U in the stage of remission, respectively. All these values were significantly lower than that of healthy controls [(117.1 ? 50.30)% and 31.3 ? 9.3U, respectively, P

Objective To evaluate the effects of two different dosage of rosuvastatin on endothelial dysfunction in diabetic rats. Methods The 24 diabetic rats were randomly divided into three groups (n=8,each): diabetic control group, 20 mg rosuvastatin daily (RV 20 mg group) and 10mg rosuvastatin daily for 8 weeks (RV 10 mg group) and normal control group (SD group). The levels of blood glucose, lipid, nitric oxide(NO) and endothelin-1 (ET-1) were measured before and 8 weeks after treatment. Results The levels of blood glucose were higher in all diabetic rats groups than in SD group before experiment (P<0. 01). Compared with diabetic rats control group, blood glucose was slightly lower in RV 10 mg group and RV 20 mg group at 8 weeks (P>0. 05). The plasma NO level was significantly lower in diabetic rats control group than in SD group (P<0. 05).After 8 weeks, plasma NO levels were significantly higher in RV 20 mg and RV 10 mg groups than in diabetic rats control group (P<0. 01 or P<0. 05). The plasma levels of ET-1 was significantly higher in diabetic rats control group than in SD group (P<0. 01). After 8 weeks, plasma ET-1 levels were significantly lower in RV 20 mg and RV 10 mg group than in diabetic rats control group (P<0. 01).Meanwhile, the plasma lipids were lower in RV 20 mg and RV 10 mg group than in diabetic control group (P<0. 05 or P<0. 01). Conclusions Rosuvastatin can adjust blood lipids and significantly improve endothelial function in diabetic rats by increasing plasma NO level and decreasing plasma ET-1 level.

Objective To research the relationship between the myocardiac ischemic activity and degree of depression in elderly patients.MethodsThe Center For Epidemiological Studies-Depressive Scale(CES-D) was administered to evaluate depressive degree for 121 patients who were defined as coronary artery diseased by coronary angiography (CAG); group A (n=64) for no depressive symptoms,group B (n=34) for minor depression, group C (n=23) for major depression were studied to observing the myocardial ischemia using Holter's recording and exercise testing.ResultsCAG showed that single vessel disease was more frequently in group A;single,double and three-vessel disease showed approximative proportion in group B,three-vessel disease was more frequently in group C.The times of ST-depress were (4.2±1.3),lasting time of ST-depress was (35.8±9.2) min,and index of ST-depress was (3.28±0.9) min/h,which were higher than those of group A [(1.8±0.3),(16.6±4.2) min,(1.76±0.4) min/h] and group C [(2.1±0.7),(17.8±5.8) min,(1.69±0.5)min/ h](P<0.05);There was significantly frequent myocardial ischemia in group B than in group A during exercise testing (χ2=3.274,P<0.05). patients in group C tended to have approximative incidence of ischemia compared with group A during daily living,but more incidence of ischemia than group B during exercise testing(χ2=5.473,P<0.05).ConclusionThe depressive degree was associated with severity of coronary artery disease,mild to moderate symptoms of depression are associated with an increased likelihood of myocardial ischemia during daily living and exercise,but patients with severity depression absence symptoms of myocardial ischemia during daily living,and exhibit markedly myocardial ischemia during exercise.
