Objective To evaluate the effects of the short-term intervention lifestyle intervention on metabolic measurements of community patients with impaired glucose regulation (IGR). Methods A total of 90 IGR participants were randomly assigned to the control group (n=45) or the intervention group (n= 45). The subjects in the control group received routine diet and physical exercise advice once a month. The subjects in the intervention group received additional individualized diet counseling and circuit-type resistance training. Metabolic parameters were compared before or after the intervention between the two groups. Results In oral glucose tolerance test (OGTT),2-h plasma glucose (PG) and homeostasis model of insulin resistance index (HOMA-IR) were significantly decreased in the intervention group at 3 months(F= 13.47 or 82.25 ,both P < 0.05). Body mass index (t=-2.44, P<0.05), systolic blood pressure (t= -3.39, P<0.05), diastolic blood pressure (t=-3.97, P<0.05), fasting plasma glucose (t=-3.89, P<0.05),2-h PG (t=-7.22,P <0.05) ,total cholesterol (t=-2.72,P<0.05),low-density lipoprotein cholesterol (t=-2.74, P<0.05), and glycosylated hemoglobin A1 C (t=-3.73, P<0.05) were significantly declined in the intervention group compared to the control group (all P<0.05). Conclusions Intensive lifestyle intervention can significantly improve the metabolic markers of IGR subjects and should be used to prevent type 2 diabetes.
Résumé
Object To study the chemical constituents of Dracaena cochinchinensis (Lour.) S. C. Chen. Methods The constituents were isolated on silica gel chromatography, preparative TLC, and spectral data. Results Six compounds were isolated and identified from the resin of D. cochinchinensis as: 1, 2, 4, 5-tetrachloro-3, 6-dimethoxybenzene (Ⅰ), cholest-4?-methyl-7-en-3?-ol (Ⅱ), cholest-4?-methyl-7-en-3-one (Ⅲ), hexacosane (Ⅳ), cholest-7-en-3?-ol (Ⅴ), cholest-7-en-3-one (Ⅵ). Conclusion Compounds Ⅳ-Ⅵ were isolated from D. cochinchinensis for the first time.
Résumé
Practical teaching of medical ethics is the key point in judging the effectiveness of the course.After 27 years of teaching efforts and exploration,the teaching of medical ethics in our college has gradually formed the basic form of practical teaching,such as case teaching,group discussion,scientific research activities,case assessment,the combination of medical ethics teachers and clinical teachers in the teaching process.But more attention and efforts are still needed in the following issues,including building a scientific evaluation system for the course of medical ethics,focusing on the continuity of practical and systematic teaching,dedicated practice of medical ethics course,and handling new arising problems in modern medical and healthcare practice.
