Rat hepatic oval cell model was induced by hyperglycemia and streptozotocin in vivo. Expression of insulin and mRNA expression of pancreatic transcription factors(Nkx6.1, PDX-1) were carried out. It showed that under high glucose, liver tissues were positive for insulin staining, the expression of Nkx6.1 and Pdx-1mRNA was significantly enhanced, and insulin-1mRNA was found to be expressed. The result suggests that under high glucose, hepatic oval cells can differentiate into insulin-producing cells.

Objective To observe the effect of paeoniflorin on insulin resistance in rats fed with high-fat diet and to investigate the possible mechanisms.Methods Male Sprague Dawley (SD) rats were randomized into 4 groups:normal control,high-fat diet,high-dosage paeoniflorin (HDP group),and lowdosage paeoniflorin (LDP group).The control group was fed with ordinary diet,while the others with highfat diet,paeoniflorin intervention groups were given low-or high-dosage paeoniflorin by intraperitoneal injection.After 6 weeks,fasting serum triacylglycerol (TG),total cholesterol (TC),free fatty acids (FFA),fasting blood glucose (FBG),and insulin were determined.Insulin sensitivity index (ISI) were calculated and then the animals were sacrificed to acquire epididymal fat mass.The tumor necrosis factor alpha (TNFα) and glucose transporter 4 (Glut4) expressions in adipose tissue were detected by quantitative realtime polymerase chain reaction(PCR).Results Compared with high-fat fed group,HDP group had lower epididymal fat pad weight,reduced level of FBG,insulin and FFA (P <0.05) and improved ISI(-5.84 ± 0.24 vs-6.44 ± 0.25,P < 0.05).LDP group had similar trends.In adipose tissue,the TNFα expression in LDP and HDP group was lower,Glut4 expression in HDP group was higher than that of high-fat fed group (P < 0.05).Conclusion Paeoniflorin can reduce visceral adipose content,inhibit TNFα expression and increase Glut4 expression in adipose tissue,eventually lower glucose,and improve insulin resistance caused by high-fat diet.

Mitochondria, the power house of cells, are important organelles in eukaryotic cells. Having their own unique and complete DNA (mtDNA) and genetic system, mitochondria play an essential role in cellular energy metabolism, intracel?lular signaling and apoptotic pathways, as well as many other biological functions, which are closely related with cellular met?abolic network. A disruption of mitochondrial genes can therefore result in mitochondrial dysfunction and human diseases, thus they have been widely used in molecular biology, development biology, genetics, forensic identification and clinical diag?nosis. Consequently, sequencing mitochondrial genome has shown great significance in mitochondrial structure and function research. In this review, research progress in mitochondrial genome sequencing method is summarized, mainly focusing on Sanger sequencing, long-PCR and next-generation sequencing. Also rolling circle amplification and indirect sequencing of mtDNA are reviewed. The ambiguities caused by numts in indirect sequencing are mentioned and resolved.

Objective To evaluate the effects of metformin on thyrotropin(TSH)levels. Methods From the patients with type 2 diabetes mellitus or metabolic syndrome, 48 patients with primary hypothyroidism were enrolled and grouped. 17 patients were treated only with metformin(group A), 19 patients with metformin and stable L-T4substitution(group B), and the remaining 12 patients with antidiabetic drugs(other than metformin)and L-T4(group C). Meanwhile, 20 euthyroid patients with other thyroid abnormalities(group D)and 30 patients without thyroid diseases(group E)served as control. TSH, FT3, FT4, TT3, TT4, and blood glucose were determined regularly in all these subjects. Results After administration of metformin for 12 months, serum TSH were decreased in group A [(5.05±1.07 vs 2.61±0.91)mU/L, P<0.01] and group B [(2.67±1.03 vs 1.35±0.74)mU/L, P<0.01]. No difference was found in FT3and FT4in both groups. TSH levels were raised from(1.30±0.71)to(2.58±1.02)mU/L(P<0.01)within 8~12 weeks in 13 out of 15 patients after metformin withdrawal. Serum TSH and thyroid hormones in the other 3 groups were not significantly changed. Conclusion Administration of metformin may lead to reduction of serum TSH level.
