RESUMO
Objective:To observe the effect of nutrition intervention and exercise rehabilitation treatment on the sarcopenia in elderly patients with type 2 diabetes.Methods:It was a cross-sectional study. From March 2019 to September 2020, 101 elderly patients with type 2 diabetes complicated with sarcopenia treated in the Department of Endocrinology of Tianjin Third Central Hospital were enrolled in this study. The patients were divided into four groups with propensity score matching method: sarcopenia education group without nutrition and resistance training group (group A, n=22), simple nutrition intervention group (group B, n=28), nutritional intervention combined with resistance training group (group C, n=27) and nutritional intervention combined with aerobic and resistance training group (group D, n=24). All the patients were intervened for 24 weeks, two patients in groups C and D dropped due to their own reasons. The 25-dihydroxy vitamin D3 (25(OH)D 3), grip strength, muscle mass of the limbs and short physical performance battery (SPPB) scores were measured before and 24 weeks after the intervention in all the participants. Results:After the intervention, the 25(OH)D 3 levels in the B, C, D groups was (33.45±4.05), (33.68±4.69), (34.28±5.58) μg/L, respectively, all were higher than those before the treatment (all P<0.01), and there was no significant differences among the three groups ( P>0.05). The muscle mass in the B, C, D groups after intervention was 5.650 (5.102, 6.658), 6.601 (6.007, 7.156) and 6.520 (6.017, 7.302) kg/m 2, respectively, all were significantly higher than those before the treatment (all P<0.01); the muscle mass in group C and D increased more significantly than that in group B ( P<0.01), but there was no significant differences between group C and D ( P>0.05). After the intervention, the muscle strength in the C and D groups was 20.60 (19.20, 24.55) kg and 21.15 (19.43, 26.63) kg, and the SPPB scores was 8.00 (7.00, 9.00) points and 8.00 (8.00, 9.00) points, respectively, all were higher than those before the intervention (all P<0.01), but there was no significant differences between the two groups(both P>0.05). The SPPB function score in group D was better than that in group C, the difference was statistically significant ( P<0.05). Conclusions:Nutritional intervention can improve the muscle mass in elderly type 2 diabetes patients with sarcopenia. Combined with rehabilitation training, the muscle strength and muscle function of these patients could also be improved, and the improvement of muscle mass is better than that in patients receiving nutritional intervention only. In terms of increasing muscle strength, the two kinds of rehabilitation training are equivalent. If combined with aerobic exercise, it can also improve the muscle function of these patients.
RESUMO
Objective@#To investigate the effect of dietary control combined with different exercise modes on plasma vaspin, irisin, and metabolic parameters in patients with non-alcoholic fatty liver disease (NAFLD) through a randomized open parallel-controlled study.@*Methods@#The patients aged 30-65 years who visited Tianjin Third Central Hospital from January 2013 to December 2014 and were diagnosed with NAFLD by liver ultrasound and fat content determination were screening, and 474 patients were enrolled in this randomized controlled trial and divided into aerobic exercise group, resistance exercise group, and control group. All patients received dietary intervention. The three groups were compared in terms of biochemical parameters, fat content, NFS score, energy metabolic parameters, body composition index, and levels of vaspin and irisin at baseline and after 6 months of intervention. SPSS 19.0 was used for statistical analysis. The t-test, the Mann-Whitney U test, the chi-square test, and an analysis of variance were used for comparison between groups. The multiple imputation method was used for missing data, and the results were included in the intention-to-treat analysis.@*Results@#There were no significant differences in age, sex, anthropometrical parameters, and biochemical parameters between the three groups at baseline. Compared with dietary control alone, aerobic exercise and resistance exercise helped to achieve significant reductions in waist circumference, diastolic pressure, percentage of body fat, volatile fatty acid, fasting blood glucose, homeostasis model assessment of insulin resistance, triglyceride, low-density lipoprotein cholesterol, free fatty acid, uric acid, alanine aminotransferase, and liver fat content after 6 months of intervention (P < 0.05). The aerobic exercise group had a significant increase in non-protein respiratory quotient and significant reductions in body mass index and aspartate aminotransferase after intervention, as well as a significant increase in resting energy expenditure and significant reductions in abdominal fat ratio and total cholesterol after 6 months of resistance exercise (P < 0.05). The aerobic exercise group and the resistance exercise group had a significant reduction in vaspin and a significant increase in irisin after intervention (P < 0.05), and the resistance exercise group had significantly greater changes in these two adipokines than the aerobic exercise group (P < 0.05).@*Conclusion@#Exercise therapy is an effective method for the treatment of metabolism-associated diseases, and a combination of resistance and aerobic exercises is more reasonable and effective in clinical practice. As a relatively safe exercise mode, resistance exercise can also effectively improve the metabolic state of NAFLD patients.
RESUMO
Objective To evaluate the accuracy of different noninvasive methods for the diagnosis of nonalcoholic steatohepatitis(NASH) and hepatic fibrosis in patients with non-alcoholic fatty liver disease (NAFLD) combined with type 2 diabetes mellitus(T2DM). Method A prospective comparative study was performed for 91 patients with T2DM and NAFLD, which were diagnosed by glucose tolerance test and liver biopsy. The height and body mass of the patient were measured, and the body mass index(BMI) was calculated. The fasting venous blood of the patient was collected, and then the blood routine, liver function and ferritin were measured. NPS, neutrophil lymphocyte ratio(NLR), BARD score, FIB-4 index, APRI, and NAFLD fibrosis score(NFS) were calculated. All patients underwent transient elastography (Fibrotouch) to evaluate the degree of liver stiffness measurement (LSM) and controlled attenuation parameter. All the liver biopsy specimens were categorized by SAF as the gold standard for evaluating NASH and liver fibrosis NASH. Correlation analysis was applied to compare the correlation between the noninvasive methods and SAF. The receiver operating characteristic (ROC) curve and the area under the curve (AUC) were used to assess the diagnostic value of the noninvasive methods for NASH and liver fibrosis NASH. Results In T2DM combine with NAFLD patients, NPS, LSM, NFS, APRI, FIB4 and BMI scores were positively correlated with SAF (r value was 0.509, 0.508, 0.252, 0.396, 0.313 and 0.213, respectively; P value was <0.001, <0.001, 0.016,<0.001, 0.003 and 0.043, respectively). LSM, NPS, NFS and FIB4 scores were positively correlated with liver fibrosis (r value was 0.535, 0.337, 0.315 and 0.315, respectively; P value was <0.001, 0.001, 0.002, 0.002, respectively). The ROC curve shows that the area under the curve of NPS, LSM, APRI, FIB4 and BMI for diagnosing NASH was 0.838, 0.760, 0.734, 0.623 and 0.682, respectively, and P value was 0.000, 0.000, 0.000, 0.044 and 0.003, respectively. For the diagnosis of fibrotic NASH, that value of LSM, NFS, FIB4 and NPS was 0.795, 0.765, 0.686 and 0.623, respectively, and P value was 0.000, 0.001, 0.020 and 0.123, respectively. Conclusions NPS, LSM and APRI have good clinical diagnostic value for NASH. LSM and NFS have good diagnostic value for fibrotic NASH.
