ABSTRACT
【Objective】 To investigate the correlation between body composition and thyroid function indicators in type 2 diabetic patients with euthyroidism of different genders. 【Methods】 Type 2 diabetic patients with euthyroidism who were hospitalized in the Endocrinology Department of The Second Affiliated Hospital of Xi’an Jiaotong University from February 2016 to September 2018 were enrolled in this study. Bioelectric impedance analysis was used to measure body composition, and the thyroid function indicators (FT3, FT4, and TSH) were tested. The male and female subjects were matched according to the ratio of 2:1 using the propensity score matching method, and the correlation between body composition and thyroid function indicators was studied in different genders by correlation analysis. 【Results】 The basal metabolic rate, trunk fat mass, fat-free mass, fat-free mass index, bone mass, water mass, total body muscle mass, skeletal muscle mass, and skeletal muscle index were positively correlated with FT3 in male patients (P<0.05). The percentage of body fat mass and fat mass index were positively correlated with FT3 and TSH (P<0.05), and the percentages of lean mass, water mass, and total body muscle mass were negatively correlated with FT3 and TSH (P<0.05), and the basal metabolic rate was negatively correlated with FT4 (P<0.05) in female. 【Conclusion】 In euthyroid type 2 diabetic patients, the correlation between body composition and thyroid function indicators are different between males and females. In males, only FT3 is positively correlated with basal metabolic rate, trunk fat mass, and fat free-related composition; while in females, both FT3 and TSH are positively correlated with fat-related composition, but negatively correlated with fat-free-related composition.
ABSTRACT
ObjectiveTo preliminarily investigate the relationship between the chronic hepatitis C virus (HCV) genotypes, 2a and 1b, and thyroid hormone levels and autoantibodies. MethodsIn patients who were admitted to our hospital and diagnosed with chronic hepatitis C from October 2013 to December 2014, reverse transcription-polymerase chain reaction was performed to determine the HCV genotype. A total of 196 patients with HCV genotype 2a or 1b were enrolled as subjects. The levels of thyroid hormone and thyroid autoantibodies were determined by chemiluminescence immunoassay, and the relationship between the HCV genotype and thyroid function was analyzed. Between-group comparison of continuous data was performed by t test, and the risk factors were evaluated by logistic regression analysis. ResultsIn the 196 patients with hepatitis C, 57.7% (n=113) were infected with HCV-2a, and 42.3% (n=83) were infected with HCV-1b. There were no significant differences in levels of thyroid hormone and thyroid autoantibodies between patients with HCV-2a and HCV-1b (P＞0.05). In the 92 patients who were treated with interferon, there were no significant differences in levels of thyroid hormone and thyroid autoantibodies between patients with HCV-2a and HCV-1b (P＞0.05). Logistic regression analysis showed that the genotype classification was not a risk factor for abnormal thyroid autoantibodies (OR=2.012, P＞0.05). ConclusionThere is no intrinsic link between chronic HCV genotype classification and thyroid function. The genotype classification has no substantial effect on thyroid function.
ABSTRACT
Objective:To observe the effect of metformin on the expression of SIRT1 and UCP2 in rat liver of type 2 diabetes mellitus (T2DM) with nonalcoholic fatty liver disease (NAFLD), and discuss the pathogenesis of T2DM with NAFLD, and the treatment with and possible mechanism of metformin.Methods:Thirty-six male SD rats were randomly divided into a normal control group (group NC, n=12), a T2DM with NAFLD group (group MC, n=12), and a metformin group (group A, n=12). We established the model of T2DM with NAFLD rats by feeding high-fat and high-sugar diet and injecting STZ. After the success establishment of the model, the metformin group was given metformin 300 mg/(kg.d) for 8 weeks. At the end of the experiment, we measured FBG, ALT, AST, TC, TG, HDL-C, LDL-C, VLDL, FFAs, FINs and HOMA-IR respectively in group NC, MC and A. We observed the change of liver tissue pathology by HE, determined the expression of SIRT1 and UCP2 in rat liver by immunohistochemical method and real-time quantitative method. Results:FBG, ALT, AST, TC, TG, LDL-C, VLDL, FFAs, FINs and HOMA-IR were higher in group MC than in group NC (P Conclusion:The expression of SIRT1 is low and the expression of UCP2 is high in rat liver of T2DM with NAFLD. Metformin can increase the expression of SIRT1 and reduce the expression of UCP2, with negative correlation between the expression of SIRT1 and UCP2.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate serum APPL1 level in patients with newly diagnosed type 2 diabetes mellitus (T2DM) and analyze its correlation with body mass index (BMI), waist-to-hip ratio (WHR), blood pressure, fasting plasma glucose, fasting blood insulin, HbA1c, and insulin resistance (HOMA-IR).</p><p><b>METHOD</b>Serum APPL1 levels were determined using ELISA in 22 normal control subjects and 63 patients with newly diagnosed T2DM, and HOMA-IR of the subjects was calculated using the HOMA model.</p><p><b>RESULTS</b>The diabetic patients had significantly elevated levels of serum APPL1 compared with the control subjects (85.71∓27.39 vs 64.52∓16.28 pg/ml, P<0.01), with also significantly increased BMI, WHR, SBP, FINS, LgHOMA-IR (P<0.01) and LDL-C (P<0.05) but lowered HDL-C (P<0.01). Fasting serum APPL1 levels were positively correlated with FPG, FINS, and HOMA-IR (r=0.215, 0.297, 0.334, P=0.014, 0.006, 0.002, respectively). In multiple linear regression analysis with APPL1 as the dependent variable, HOMA-IR (β=0.329, P=0.002) was included in the equation.</p><p><b>CONCLUSION</b>Patients with newly diagnosed T2DM have elevated serum APPL1 levels, suggesting the involvement of APPL1 in the development of T2DM.</p>

<p><b>OBJECTIVE</b>To observe the expression of SIRT1 and mitochondrial uncoupling protein 2 (UCP2) in the liver of rats with type 2 diabetes mellitus (T2DM) and nonalcoholic fatty liver (NAFLD) and explore the possible pathogenesis of T2DM and NAFLD.</p><p><b>METHODS</b>Twenty-four male SD rat were randomized equally into control group and T2DM and NAFLD group (MC group), fed with standard diet and high-fat and high-sugar diet, respectively. At 12 weeks, the rats in MC group received a single dose of STZ (30 mg/kg) injected into the abdominal cavity for pancreatic islet destruction, and those in the control group received an equivalent volume of citric acid buffer. At 14 weeks, the body weight, FBG, hepatic function, blood lipid levels, FFAs, FINs and HOMA-IR of the rats were measured, and the liver pathology was examined with HE staining. The expression of SIRT1 and UCP2 in the rat liver was detected by immunohistochemistry and real-time quantitative PCR.</p><p><b>RESULTS</b>At 14 weeks, FBG, ALT, AST, TC, TG, LDL-C, VLDL, FFAs, FINs and HOMA-IR were significantly higher and HDL-C was significantly lower in MC group than in the control group (P<0.05). Pathological examination showed good structural integrity of the liver in the control group, and the liver cells were closely arranged with rich cytoplasm and round cell nuclei; in MC group, moderate to severe fatty liver was detected, and the liver cells showed severe ballooning degeneration and contained lipid vacuoles in the cytoplasm. The expression of SIRT1 was significantly lower and UCP2 significantly higher in MC group than in the control group (P<0.05).</p><p><b>CONCLUSION</b>The expression of SIRT1 is significantly lowered and UCP2 increased in the liver of rats with T2DM and NAFLD.</p>
