Objective To explore the apoptosis of alveolar epithelial cell(AEC)and the dynamic changes of Caspase-3 mRNA and Bax and Bcl-2 expression in premature rat with hyperoxia-induced chronic lung disease(CLD).Methods Sixty premature rats within 1 day after birth were randomly divided into 2 groups:hyperoxia group(n=30)and control group(n=30).Hyperoxia-induced premature rat CLD models were prepared,and situ nick end-labeling(TUNEL),reverse transcription polymerasechain reaction(RT-PCR)and immunohistochemical technique were used to determine apoptosis index(AI)of AEC and the expressions of Caspase-3 mRNA and Bax and Bcl-2 proteins in lung tissues at 1,3,7,14 and 21 d after birth.Results Compared with control group,in the hyperoxia group,on the third day after exposured to hyperoxia,the AI of AEC and the expressions of Caspase-3 mRNA and Bax began to increase,and the expression of Caspase-3 mRNA was kept at high level on 7-21 d.The expression of Bcl-2 began to decrease on 7 d,and significantly decreased on 7-21 d.AI of AEC was positively correlated with the expression of Caspase-3 mRNA and Bax,and negatively with the expression of Bcl-2.Conclusions Hyperoxia may induce the increased expression of Caspase-3 mRNA,which might result in the abnormal expression of Bax and Bcl-2 in lung tissues and their imbalance,which might be one of the underlying mechanisms of apoptosis of AEC in premature rats with CLD.

Objective To investigate the effects of basal and early phase insulin secretion on plasma glucose level in type 2 diabetes. Methods Plasma glucose and true insulin levels were measured at 0, 30, 60, 120 min during standard meal test in 81 patients with type 2 diabetes. Insulin sensitivity index (ISI) and insulin secretion index (?I 30 /?G 30 ) were calculated for evaluating the insulin sensitivity. Contributions of basal and early insulin secretion to plasma glucose level were evaluated by multivariate regression analysis with SAS software. Results ISI and ?I 30 /?G 30 showed nearly equal effects on plasma glucose levels by multivariate regression analysis. Among insulin levels of different time points during standard meal test, basal and postprandial 60 min insulin levels played important roles in changes of plasma glucose levels. The effect of fasting insulin on the area under plasma glucose curve was stronger than that of ?I 30 /?G 30 . Conclusion Both basal and early insulin secretions greatly contribute to glycemic control.

To observe therapeutic effects of acupuncture on female's climacteric depression and to study on the mechanism. Methods Sixty cases enrolled were randomly divided into an acupuncture group and a control group, 30 cases in each group. In the acupuncture group, acupuncture were given at Ganshu (BL 18), Shenshu (BL 23), Xinshu (BL 15), etc. with uniform reinforcing-reducing method, once each day, and the control group were treated with oral administration of fluexertine hydrochloride, 20 mg, once daily. HAMD scale was used for assessment before treatment and 2,4,6 weeks after treatment. Blood dopamine (DA), norepinephrine (NE) and 5-hydroxy-indoleacetic acid (5-HIAA) contents were detected before treatment and after one therapeutic course. Results The total effective rate was 86.7% in the acupuncture group and 92.9% in the control group with no significant difference between the two groups (P > 0.05). After treatment, DA content increased significantly in the acupuncture group with a significant difference as compared with that of the control group (P < 0.05); and after treatment NE and 5-HIAA contents in the two groups significantly increased as compared with that before treatment (P < 0.05, P < 0.01), with no significant difference between the two groups (P > 0.05). Conclusion Acupuncture can benignly and comprehensively regulate general functions, and increase contents of monoamines in the body, so as to play the role of anti-depression.
