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.

BACKGROUND:Neuregulin 1 has been shown to be characterized in cell proliferation,differentiation,and vascular growth.Human amniotic mesenchymal stem cells are important seed cells in the field of tissue engineering,and have been shown to be involved in tissue repair and regeneration. OBJECTIVE:To construct human amniotic mesenchymal stem cells overexpressing neuregulin 1 and investigate their proliferation and migration abilities,as well as their effects on wound healing. METHODS:(1)Human amniotic mesenchymal stem cells were in vitro isolated and cultured and identified.(2)A lentivirus overexpressing neuregulin 1 was constructed.Human amniotic mesenchymal stem cells were divided into empty group,neuregulin 1 group,and control group,and transfected with empty lentivirus and lentivirus overexpressing neuregulin 1,or not transfected,respectively.(3)Edu assay was used to detect the proliferation ability of the cells of each group,and Transwell assay was used to detect the migration ability of the cells.(4)The C57 BL/6 mouse trauma models were constructed and randomly divided into control group,empty group,neuregulin 1 group,with 8 mice in each group.Human amniotic mesenchymal stem cells transfected with empty lentivirus or lentivirus overexpressing neuregulin-1 were uniformly injected with 1 mL at multiple local wound sites.The control group was injected with an equal amount of saline.(5)The healing of the trauma was observed at 1,7,and 14 days after model establishment.Histological changes of the healing of the trauma were observed by hematoxylin-eosin staining.The expression of CD31 on the trauma was observed by immunohistochemistry. RESULTS AND CONCLUSION:(1)Human amniotic mesenchymal stem cells overexpressing neuregulin-1 were successfully constructed.The mRNA and protein expression of intracellular neuregulin 1 was significantly up-regulated compared with the empty group(P<0.05).(2)The overexpression of neuregulin 1 promoted the migratory ability(P<0.01)and proliferative ability of human amniotic mesenchymal stem cells(P<0.05).(3)Human amniotic mesenchymal stem cells overexpressing neuregulin 1 promoted wound healing in mice(P<0.05)and wound angiogenesis(P<0.05).The results showed that overexpression of neuregulin 1 resulted in an increase in the proliferative and migratory capacities of human amniotic mesenchymal stem cells,significantly promoting wound healing and angiogenesis.
