OBJECTIVETo observe the effect of heart protection on diabetic cardiomyopathy in rats by tripterysium glucosides.

METHODThe rat diabetic cardiomyopathy rats model are made by streptozotocin, then divided into tripterysium glucosides group (n=8) and model group (n=8). In addition, the control group is established (n=8). Glucosides group was orally administrated tripterysium glucosides (18 mg x kg(-1)), the control groups was orally administrated same volume NS for 3 months. Blood sugar, heart function and cardiac index were detected after 3 months. Immunohistochemical techniques were used to detect NF-kappaB and ICAM-1 expression. Ultrastructure of cardiac muscle cell were observed by electronmicroscope.

RESULTCompared with model group, cardiac index was decreased after tripterysium glucosides administration, and LVSP, LVEDP, + dp/dtmax, -dp/dtmax, were improved, and the expression of nuclear Factor-kappaB (NF-kappaB) and intercellular adhension molecule-1 (ICAM-1) was inhibited. Ultrastructure of cardiac muscle cell such as mitochondrion and cardiac muscle fibers was atttenuated.

CONCLUSIONTripterysium glucosides could protect rat diabetic cardiomyopathy rats heart. These function may be related to inflammatory reaction inhibition and immunosuppression of tripterysium glucosides.

OBJECTIVETo develop a non-pharmacotherapy program for patients with hyperlipidemia and assess its effectiveness.

METHODSA cluster control trial was used. The experimental group was given non-pharmacotherapy for hyperlipidemia once a week for 6 weeks; the content of non-pharmacotherapy included the basic knowledge about hyperlipidemia, a guide of changing unhealthy diet and life-style. Patients were followed for once every two weeks in the department of out-patient. The control group received general care conducted by university clinicians, without the non-pharmacotherapy program. A self-completion questionnaire on hyperlipidemia-related knowledge level, questionnaires on diet and exercise, body weight, body height and the serum TG, TC were measured at entry point and at the end of 6 month.

RESULTSOne hundred and fifty-four patients in experimental group and 150 patients in control group completed the study. The non-pharmacotherapy group showed a significant increase of knowledge on hyperlipidemia in the experimental group comparing with the control group: the mean (sd) score of hyperlipidemia-related knowledge were 22.5 (4.8), 17.4 (4.2) (95% CI: 4.1, 6.1). The diet score and the proportion of regular physical activity had increased 27.20%, 21.78% respectively in experimental group. The mean (sd) of serum TG, TC and body mass index (BMI) for experimental group [2.0 (0.9) mmol/L, 5.4 (0.9) mmol/L, 23.4 (1.9)] lowered significantly comparing to those for control group [2.4 (0.9) mmol/L, 5.9 (1.0) mmol/L, 24.2 (3.0)].

CONCLUSIONNon-pharmacotherapy seemed to be an important intervention for the patients with hyperlipidemia. If same patients with hyperlipidemia failed to respond to non-pharmacotherapy, it is necessary to use pharmacotherapy. However, non-pharmacotherapy should be viewed as basic therapy.
