Objective To evaluate the effect of exercise-diet behavior intervention based on the transtheoretical model in patients undergoing weight loss surgery.Methods By convenience sampling,72 patients undergoing weight loss surgery in a tertiary general hospital in Xinxiang City,Henan Province from February 2021 to October 2022 were selected as the research subjects.By a random number table method,they were divided into a test group and a control group,with 36 cases in each group.The test group received exercise-diet behavior intervention based on the trans-theoretical model,while the control group received conventional intervention.The intervention began on the first day after admission and ended 6 months after surgery.The body mass index,body fat,lean body mass,diastolic blood pressure,systolic blood pressure,fasting blood glucose,insulin resistance index(HOMA-IR),Health Promoting Lifestyle Profile-Ⅱ(HPLP-Ⅱ)score,and Short-Form-36 Health Survey(SF-36)score were compared between the 2 groups before and after surgery for 3 and 6 months,as well as the complications within 6 weeks after surgery.Results The results of repeated measures analysis of variance showed that there was an interaction between the 2 groups in terms of anthropometric measurements,blood pressure and blood glucose,HPLP-Ⅱ scores,and SF-36 scores,with statistically significant differences(P＜0.001).After 6 months of surgery,the body mass index(23.32±2.32),body fat(24.10±3.46)kg,and lean body mass(41.64±3.24)kg in the test group were lower than(27.32±3.64),(28.46±4.18)kg,and(46.68±4.65)kg in the control group,and the differences were statistically significant(P＜0.001).At 3 and 6 months after operation,the diastolic blood pressure,systolic blood pressure,fasting blood glucose and HOMA-IR of the test group were lower than those of the control group,and the differences were statistically significant(P＜0.05).The HPLP-Ⅱ score of the test group was higher than that of the control group at 3 and 6 months after operation(P＜0.001).The SF-36 score of the test group was significantly higher than that of the control group at 6 months after operation(P＜0.05).The incidence of complications in the test group was 2.56％,which was not significantly different from 19.44％in the control group(P＞0.05).Conclusion The exercise-dietary behavior intervention based on the transtheoretical model can promote the formation of healthy behaviors in patients undergoing weight loss surgery,maintain weight loss effects,improve blood pressure and blood glucose levels,and enhance the quality of life of patients.

Objective To study the action and mechanism of Sancai Lianmei Particle on cell apoptosis of liver cells in Type 2 Diabetes Mellitus(T2DM)combined with Non-alcoholic Fatty Liver Disease(NAFLD).Methods High fat and sugar + STZ induced diabetic with fatty liver rats used as models,intervention with Sancai Lianmei Particle,intraperitoneal glucose tolerance test(IPGTT)to assess insulin resistance,ELISA method to detect the mice serum biochemistry,insulin levels;ELISA method to detect inflammatory factors in liver homogenate;SOD and MDA levels were monitored to assess the degree of oxidative stress;ASK1/JNK/NF-κB mRNA expression in liver tissue was monitored by Real-time PCR;apoptotic-related proteins were detected by Western blot,apoptosis of hepatocytes was assayed by TUNEL;HE staining was conducted to observe the liver tissue.Results Sancai Lianmei Particle can obviously reduce the body weight of T2DM with NAFLD model rats;reduce the levels of GHb,INS,TC,TG,LDL-C,ALT,AST,IL-1β,IL-6,TNF-α,MDA;improve insulin resistance and oxidative stress.HE staining of liver tissue showed that Sancai Lianmei Particle could alleviate the vacuolar degeneration of liver and deposition of lipid droplets.Sancai Lianmei Particle can effectively down-regulate the expressions of ASK1,JNK and NF-κB mRNA in liver tissues of model rats.Western Blot results exhibited that Sancai Lianmei Particle could significantly regulate the expression of apoptotic proteins of Bax,Caspase-3,and Bcl-2 and inhibit the apoptosis of hepatocytes.Conclusion This study proved that Sancai Lianmei Particle can improve hepatic insulin resistance and oxidative stress,slow the progression of NAFLD by regulating liver cell apoptosis based on ROS-ASK1-JNK/NF-κB pathway.
