Changes and clinical significance of serum vaspin levels in patients with type 2 diabetes

L. Yang, Chen, S. J., Yuan, G. Y., Wang, D., and Chen, J. J., “Changes and clinical significance of serum vaspin levels in patients with type 2 diabetes”, vol. 14, pp. 11356-11361, 2015.

We investigated serum visceral adipose tissue-derived serpin (vaspin) levels in patients with normal glucose regulation and recently diagnosed type 2 diabetes (T2DM) and explored the association between vaspin and body mass index, age, gender, glucose, lipid metabolism, and insulin sensitivity. Fasting serum vaspin levels in 66 patients with T2DM and 48 normal subjects were detected using enzyme-linked immunosorbent assay. We found that serum vaspin levels in the DM group were 0.65 ± 0.13 mg/L in non-obese patients and 1.13 ± 0.25 mg/L in obese patients.

TNF-αG-308A polymorphism is associated with insulin resistance: a meta-analysis

H. G. Wang, Yang, J., Han, H., Xu, F., Bian, Y., Zhang, H., and Wang, J. L., “TNF-αG-308A polymorphism is associated with insulin resistance: a meta-analysis”, vol. 14, pp. 563-573, 2015.

Tumor necrosis factor-α (TNF-α) promoter polymorphisms has been reported to be associated with obesity and insulin resistance and gained widespread attention. However, results obtained so far are quite conf‍‍licting. We therefore performed a meta-analysis to address this issue, basing on 17 studies from electronic databases (MEDLINE and EMBASE).

Role of APN and TNF-α in type 2 diabetes mellitus complicated by nonalcoholic fatty liver disease

X. Lin, Zhang, Z., Chen, J. M., Xu, Y. Y., Ye, H. R., Cui, J., Fang, Y., Jin, Y., Zhu, D. R., and Yuan, L., “Role of APN and TNF-α in type 2 diabetes mellitus complicated by nonalcoholic fatty liver disease”, vol. 14, pp. 2940-2946, 2015.

Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease caused by non-excessive alcohol consumption and is the most common cause of elevated levels of serum liver enzymes. We examined changes in adiponectin (APN) and tumor necrosis factor-α (TNF-α) in type 2 diabetes mellitus (T2DM) complicated by NAFLD and their relationships with insulin resistance (IR). Forty-two T2DM, 39 NAFLD, and 45 T2DM complicated with NAFLD (complicated group) patients were enrolled in this study.

Large-scale analysis of factors influencing nonalcoholic fatty liver disease and its relationship with liver enzymes

W. R. Bi, Yang, C. Q., Shi, Q., Xu, Y., Cao, C. P., Ling, J., and Wang, X. Y., “Large-scale analysis of factors influencing nonalcoholic fatty liver disease and its relationship with liver enzymes”, vol. 13, pp. 5880-5891, 2014.

Serum liver enzyme levels are often used effectively for the evaluation of nonalcoholic fatty liver disease (NAFLD). We aimed to investigate the associations between serum liver enzyme levels and risks for NAFLD in over 8000 cases in a large-scale analysis. A cross-sectional survey with multiple stages and random samplings was performed from May 2007 to May 2009 on 8102 workers at Tongji University. A questionnaire was given, assessments of physical measurements, plasma glucose, lipid profiles, and liver enzymes were made, and real-time liver ultrasounds conducted.

Association between adipose tissue expression and serum levels of leptin and adiponectin in women with polycystic ovary syndrome

S. B. Lecke, Morsch, D. M., and Spritzer, P. M., “Association between adipose tissue expression and serum levels of leptin and adiponectin in women with polycystic ovary syndrome”, vol. 12, pp. 4292-4296, 2013.

We reviewed emerging evidence linking serum levels and adipose tissue expression of leptin and adiponectin in women with polycystic ovary syndrome (PCOS). Previous data obtained by our group from a sample of overweight/obese PCOS women and a control sample of normal weight controls, both stratified by BMI, were reanalyzed. Circulating levels of leptin and adiponectin were determined by commercially available enzyme-linked immuno­sorbent assays.

Metagenomic study of single-nucleotide polymorphism within candidate genes associated with type 2 diabetes in

P. N. Mukhopadhyaya, Acharya, A., Chavan, Y., Purohit, S. S., and Mutha, A., “Metagenomic study of single-nucleotide polymorphism within candidate genes associated with type 2 diabetes in”, vol. 9, pp. 2060-2068, 2010.

A population-based study was undertaken to evaluate linkage between single-nucleotide polymorphisms known as risk factors and type 2 diabetes in an Indian population. The study population was comprised of 40 normal glucose-tolerant individuals (21 males and 19 females) and 40 type 2 diabetes patients (21 males and 19 females). The genes and their corresponding single-nucleotide polymorphisms that we screened were VDR (rs 731236 and rs 1544410), IL-6 (rs 1800795), TCF7L2 (rs 7903146) and TNF-α (rs 1800629).
