METHODS: All patients met the NCEP-ATP Ⅲ criteria for metabolic syndrome. Histology confirmed steatohepatitis, defined as a NAS greater than five up to 3 wk prior inclusion, using the current criteria. Patients with viral hepatitis, chronic alcohol intake, drug abuse or other significant immune or metabolic hepatic pathology were excluded. Subjects were randomly assigned either to the valsartan (V) group (standard dose 80 mg o.d., n = 26), or to the telmisartan (T) group (standard dose 20 mg o.d., n = 28). Treatment had to be taken daily at the same hour with no concomitant medication or alcohol consumption allowed. Neither the patient nor the medical staff was aware of treatment group allocation. Paired liver biopsies obtained at inclusion (visit 1) and end of treatment (EOT) were assessed by a single blinded pathologist, not aware of patient or treatment group. Blood pressure, BMI, ALT, AST, HOMA-IR, plasma triglycerides (TG) and total cholesterol (TC) were evaluated at inclusion and every 4 mo until EOT (visit 6). RESULTS: At EOT we noticed a significant decrease in ALT levels vs inclusion in all patients and this decrease did not differ significantly in group T vs group V. HOMA-IR significantly decreased at EOT vs inclusion in all patients but in group T, the mean HOMA-IR decrease per month was higher than in group V. NAS significantly diminished at EOT in all patients with a higher decrease in group T vs group V. CONCLUSION: Angiotensin receptor blockers seem to be efficient in hypertension-associated NASH. Telmisartan showed a higher efficacy regarding insulin resistance and histology, perhaps because of its specific PPAR-gamma ligand effect.展开更多

METHODS: Patients (n = 64; 37 men, 27 women; mean age, 44 + 12 years) with chronic hepatitis C, genotype 1, received treatment with peg-interferon plus ribavirin. Genotyping of rs12979860 was per- formed on peripheral blood DNA. Histopathological assessment of necroinflammatory grade and fibrosis stage were scored using the METAVIR system on a liver biopsy sample before treatment. Serum viral load, ami- notransferase activity, and insulin level were measured. Insulin resistance index, body mass index, waist/hip ratio, percentage of body fat and fibrosis progression rate were calculated. Applied dose of interferon and ribavirin, platelet and neutrophil count and hemoglobin level were measured. RESULTS: A sustained virological response (SVR) was significantly associated with IL28B polymorphism (CC vs -l-r allele: odds ratio (OR), 25; CC vs CT allele: OR, 5.4), inflammation activity (G 〈 1 vs G 〉 1: OR, 3.9), fibrosis (F 〈 1 vs F 〉 1: OR, 5.9), platelet count (〉 200 × 109/L vs 〈 200 ×109/L: OR, 4.7; OR in patients with genotype CT: 12.8), fatty liver (absence vs presence of steatosis: OR, 4.8), insulin resistance index (〈 2.5 vs 〉 2.5: OR, 3.9), and baseline HCV viral load (〈 106 IU/mL vs 〉 106 IU/mL: OR, 3.0). There was no association with age, sex, aminotransferases activity, body mass index, waist/hip ratio, or percentage body fat. There was borderline significance (P = 0.064) of increased fibrosis in patients with the I-I allele, and no differences in the insulin resistance index between groups of patients with CC, CT and -IF alleles (P = 0.12). Spearman's rank correlation coefficient between insulin resistance and stage of fibrosis and body mass index was r = 0.618 and r = 0.605, respectively (P 〈 0.001). Significant dif- ferences were found in the insulin resistance index (P = 0.01) between patients with and without steatosis. Patients with the C-I- allele and absence of a SVR had a higher incidence of requiring threshold dose reduction of interferon (P = 0.07). CONCLUSION: IL28B variation is the strongest host factor not related to insulin resistance that determines outcome of antiviral therapy. Baseline platelet count predicts the outcome of antiviral therapy in CT allele patients.展开更多

Methods A cross-section study was conducted in a Xinjiang Uygur population(438 males and 716 females,aged 30 to 70 years).The fasting lipid profiles,serum glucose,insulin,and uric acid were determined.Homeostasis model assessment of insulin resistance(HOMA-IR)index was used to assess insulin resistance(IR).Binary logistic regression analysis was performed to determine risk factors for prehypertension.Blood pressure levels ofnormotensives and prehypertensives in different body mass index(BMI)categories were compared. Results Binary logistic regression analysis performed after adjustment for gender,lipids profiles,waist-to-hip ratio,uric acid,HOMA-IR,and lifestyle(alcohol drinking and smoking)showed a significantly increasing prevalence of prehypertension with BMI.The odds ratios for prehypertension against the lowest BMI group(separated by 24 and 28)were 1.934 and 2.490(95% confidence interval:1.435-2.606 and 1.825-3.399,respectively).Age was independently correlated to the increasing prevalence of prehypertension.HOMA-IR was not associated with prehypertensive.The mean diastolic blood pressure(DBP)was significantly increased with BMI categories in either normotensives or prehypertensives(P〈0.001)while the mean systolic blood pressure(SBP)was significantly increased with BMI only in normotensives(P〈0.001). Conclusions In Xinjiang Uygurs,BMI and age was the risk factors for prehypertension.DBP is significantly increased with BMI.IR is not associated with prehypertension.These findings emphasize the importance of management of obesity for the control of blood pressure and other cardiovascular complications.展开更多

Additionally, post-weaning caloric restriction and its hepatic effects were explored, as this intervention is reported as a useful measure against obesity and its related disturbances. The animals were raised in litters of nine (control, CG) or three pups during lactation. These small-litter pups were FG (fed freely) or subjected to 30% RG (caloric restriction) after weaning until 60 days of age. The increased adiposity induced by lactational overfeeding was not reversed by caloric restriction. Hepatocyte glucose metabolism and glucose tolerance test were not affected by litter size, but caloric restriction increased liver basal glucose release, diminished gluconeogenesis and retarded the glycemic decay during the insulin tolerance test. Liver glucose metabolism of young adult rats was not affected by lactational overfeeding. Up to this age, however, moderate caloric restriction had a potent influence that might compromise whole-body glucose homeostasis and prompt to insulin resistance.展开更多

(Orchidaceae), an indigenous and valuable Chinese folk medicine, has been widely used in China to treat diabetes. However, few reports are available about its constituents and activity. The present experiment was conducted to investigate the active fractions from A. chapaensis in diabetic rat model induced by high-fat diet plus streptozotocin. The total EtOH extract from the whole herbs ofA. chapaensis, half of which was partitioned in sequence with petrol ether (PE), ethyl acetate (EtOAc), n-BuOH and H2O, thus yielding four fractions, all of them were orally administered with an identical dose amount to 4 g/kg dried crude herbs once a day for consecutive two weeks to further investigate the antihyperglycemic activity. The EtOAc fraction caused a significant fall in the non-fasting blood glucose level of diabetic rats from (402.66±82.26) to (226.26±62.10) mg/dl, which may be attributed to ameliorating insulin resistance, modulating the activity of enzymatic antioxidants, reducing the content of NO, etc. Much more intact β cells in the islets of Langerhans in EtOAc fraction-treated groups than the negative control were observed, which greatly supported the morphological and functional elucidation. The OGTT evidenced that EtOAc fraction could promote the endurance capacity of acute glucose increase in diabetic rats. The EtOAc fraction of A. chapaensis contains some hypoglycemic and antioxidant principles with the potential to be developed further for the treatment of diabetes specifically associated with an insulin resistance state.展开更多
Objective: To observe different efficacies of low-frequency electroacupuncture(EA) on pancreatic endocrine system in male and female patients with simple obesity due to spleen deficiency-related dampness. Methods:...Objective: To observe different efficacies of low-frequency electroacupuncture(EA) on pancreatic endocrine system in male and female patients with simple obesity due to spleen deficiency-related dampness. Methods: A total of 80 simple obesity patients were assigned to a male group(n=37) and a female group(n=43). Both groups received a 30-minute low-frequency EA at Yinlingquan(SP 9), Sanyinjiao(SP 6), Zusanli(ST 36), Fenglong(ST 40), Quchi(LI 11), Tianshu(ST 25), Zhongwan(CV 12), Shuifen(CV 9), Qihai(CV 6) and Guanyuan(CV 4). The treatment was done once a day, and 10 times made up a course of treatment. Patients in both groups were treated for 2 courses. Then the changes in body mass index(BMI), serum insulin, insulin antibodies and leptin level in the two groups were observed and analyzed. Results: After treatment, the BMI, serum insulin, insulin antibodies and leptin levels were significantly reduced in both groups(P〈0.01 or P〈0.05); the BMI and serum insulin concentration were more significantly reduced in the male group than those in the female group(both P〈0.01); and the leptin level was more significantly reduced in the female group than that in the male group(P〈0.01). Conclusion: EA can significantly regulate BMI and pancreatic endocrine system in both men and women with simple obesity; however, there is a gender difference: better effect for men in reducing BMI and serum insulin and better effect for women in reducing serum leptin level.展开更多

Methods:The study included 33 patients (25 females and 8 males; mean age 46 years) with body mass index (BMI) values of〉40 kg/m2. Evaluations of CRP, IL-6, TNF-α, lipid profile, HOMA-IR, and fasting glucose were carried out before (baseline data) and three weeks after the treatment. The control group consisted of 20 healthy volunteers (15 females and 5 males) with a mean age of 39 years and BMI values of≤24.9 kg/m2. Results:In the blood of patients with morbid obesity we found significantly elevated levels of CRP, TNF-α, triglycerides, HOMA-IR and fasting glucose, but a de-creased level of high density lipoprotein (HDL)-cholesterol, compared with the healthy individuals. The treatment resulted in about a 9.4%reduction in body weight from 122.5 to 111.0 kg and a significant decrease in the concen-tration of CRP, but no change in TNF-αor IL-6. HOMA-IR was significantly reduced. Conclusions:The decrease in CRP level without changes in TNF-α or IL-6 concentrations after the low-calorie diet and balneological treatment, suggests that an essential amount of adipose tissue must be removed before proper adipocyte function is restored. The decrease in HOMA-IR indicates an improvement in insulin sensitivity, which is beneficial in obese patients.展开更多

文摘Objective:The aim of this study was to evaluate the concentrations of C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and the degree of homeostasis model assessment-insulin resistance (HOMA-IR) in patients with morbid obesity exposed to a three-week low-calorie diet and balneotherapy. Methods:The study included 33 patients (25 females and 8 males; mean age 46 years) with body mass index (BMI) values of〉40 kg/m2.
