ABSTRACT
Objective To investigate onthe correlation between the seven single nucleotide polymorphisms and genesis of T2DM. Methods High‐resolution melting (HRM ) curve technology was used to detect thegenotype of the seven SNPs in 202 T2DM patients and 200 healthy volunteers. The relationship between susceptible gene polymorphism and T 2DM was analyzed. Results The frequency of five SNP loci rs8050136 ,rs13266634 ,rs7578597 ,rs864745 and rs7961581 showed significant differences between T2DM patients and controls ( P1 ,while OR of rs7961581 was <1. There was no significant difference in rs10811661 and rs10923931 loci between T2DM patients and controls (OR=1). Conclusion The polymorphism of loci rs8050136 ,rs13266634 ,rs7578597 and rs864745 is associated with T2DM genesis in this study population , while rs10811661 and rs10923931 is not associated with T 2DM genesis ,and rs7961581 may be a protective factor for T2DM.
ABSTRACT
The changes of plasma myostatin levels in patients with type 2 diabetes mellitus (T2D) and their clinical correlation were investigated. We recruited 43 T2D patients and 20 age-matched healthy subjects. Plasma myostatin, lipid and glucose, and serum insulin were determined. T2D patients showed significantly higher fasting plasma glucose (FPG), serum insulin and triglyceride levels, and lower high-density lipoprotein levels than normal control subjects (P<0.01). Mean plasma myostatin level in T2D patients and health controls was (66.5±17.8) and (46.2±13.8) ng/mL, respectively. An unpaired t test showed that the increase of myostatin in the T2D patients was significant (P<0.001). In both healthy control and T2D groups, the female subjects showed higher myostatin levels than the male subjects. In the T2D patients, plasma level of myostatin was negatively correlated with body mass index (BMI, r=-0.42, P<0.01) and FPG (r=-0.51, P[Symbol: see text]0.01), but positively correlated with insulin resistance index (HOMA-IR, r=0.48, P<0.01). Up-regulation of plasma myostatin in the T2D patients and its correlation with BMI, FPG and blood insulin sensitivity suggests that plasma myostatin may be implicated in the pathogenesis of T2D and thus presented as a therapeutic target for treating the disease. Furthermore, circulating myostatin levels may be used as a biomarker for the disease.

Retrospective analysis was performed on the preoperative imaging examinations in 18 patients with primary hyperparathyroidism (PHPT). The results showed that non-invasive imaging examinations such as B ultrasound, CT, MRI and ~(99m)Tc-MIBI radionuclide scanning were of great value in locating the lesions of PHPT, ~(99m)Tc-MIBI radionuclide scanning is recommended as the method of first choice.
