[Variances of leptin mRNA in the adipose tissue of NAFLD rats intervened with the extracts of Polygonum cuspidatum compound].

The NAFLD rats were intervened with the extracts of Polygonum cuspidatum compound for 4 weeks. The reverse transcription and real-time quantitative polymerase chain reaction (RT-qPCR) methods were used to detecte the relative level of leptin mRNA in the adipose tissue of intervenient and control groups. Their variances of fat and glucose in serum were detected with the biochemical methods.

[Relationship between leptin gene of adipose tissues and nonalcoholic fatty liver disease].

Objective: To investigate leptin mRNA expressions in subcutaneous (SC) and omental (OM) adipose tissues of patients with nonalcoholic fatty liver disease (NAFLD), and their relationships with insulin resistance (IR), blood leptin, blood triglyceride, total blood cholesterol, blood glucose, body weight index and waist-hip ratio.

Methods: SC and OM adipose tissues were obtained from 10 obese and 11 nonobese NAFLD patients and from 11 obese and 13 nonobese patients without NAFLD, who served as controls. Leptin mRNA expression levels in the subcutaneous and omental adipose tissues were measured using SYBR Green I quantitative real-time PCR.

[TNF-alpha gene expression of NAFLD rat intervened by the extracts of Rizoma Polygoni Cuspidati].

The real-time qPCR method had been used to detect and analyze the non-alcohol fatty liver disease (NEFLD) model in medical intervention in this research. The relative level of TNF-alpha mRNA in adipose tissue of intervention group was lower than that of control group. Their difference was significant (t = 2.
