AIM: To investigate the repair mechanism associated with cholesterol synthesis regulated by silent information regulator 1 (SIRT1) in rat model of optic nerve damage.METHODS: Preparation of optic nerve damage in 70 rats was randomly divided into normal group (10 rats), resveratrol treatment group ( experimental group 30 rats) and PBS buffer control group ( 30 rats ) . The experimental group and control group was further divided into 3 subgroups ( each group 10 rats ) , respectively. After 7, 14, 21d injected resveratrol or PBS, optic nerve injury were observed, then the rats were sacrificed. Retina was segregated; the surviving retinal ganglion cell ( RGCs ) was counted. Dissection of optic nerve, cholesterol content of them were tested; RT-PCR was used to detect mRNA expression of SIRT1, SREBP2 and HMGCR; Western blot assay was used to test the protein expression levels of SIRT1, cholesterol regulatory element binding protein 2 (SREBP2) and HMGCR.
RESULTS:The numbers of RGCs and cholesterol levels of rat model with optic nerve injury decreased significantly (P<0. 01). The mRNA and protein expression levels of SIRT1, SREBP2 and HMGCR were all decreased in a time-dependent manner (P<0. 05). Three components of the three time points, with time injuries were aggravated, and the extent of damage was significantly reduced in the treatment group compared with the control group. But in resveratrol treatment group, the cholesterol levels and mRNA or protein expression of SIRT1, SREBP2, HMGCR in optic nerve were significantly restored in a time-dependent ( P<0.05 ) . The number of surviving RGCs restored significantly in resveratrol treatment group (P<0. 01) in a time-dependent manner.
CONCLUSION:Up-regulating the expression of SIRT1, SREBP2 and down- regulating HMGCR by resveratrol could repair the injury of optic nerve through promoting the synthesis of cholesterol in neurons and retinal ganglion cells in the repair process. SIRT1 may be as a promising new target for treatment on optic nerve damage.

Objective: To observe the effect of acupuncture on serum peptide YY (PYY) and nesfatin-1 in obese patients with insulin resistance. Methods: Ninety-eight obese patients with insulin resistance were divided into a control group and an observation group by the random number table method, with 49 cases in each group. The control group received exercise and dietary interventions, and the observation group received additional acupuncture treatment to the exercise and dietary interventions. The body mass index (BMI), body fat percentage, fasting insulin (FINS), fasting plasma glucose (FPG), homeostasis model assessment for insulin resistance (HOMA-IR), triglyceride (TG), total cholesterol (TC), and serum PYY and nesfatin-1 levels were compared before and after treatment. The efficacy was evaluated after treatment. Results: The total effective rate was significantly higher in the observation group than in the control group (P<0.05). After treatment, the BMI, body fat percentage, and serum TG and TC levels decreased significantly in both groups (P<0.05), and were significantly lower in the observation group than those in the control group (P<0.05). The FINS, FPG, HOMA-IR, and serum PYY and nesfatin-1 levels of the control group were not significantly changed after treatment (P>0.05). The FINS, FPG and HOMA-IR of the observation group decreased significantly after treatment (P<0.05), and were lower than those in the control group (P<0.05). The serum PYY and nesfatin-1 levels of the observation group increased significantly after treatment (P<0.05), and were higher than those in the control group (P<0.05). Conclusion: Based on exercise and dietary interventions, acupuncture is effective for obese patients with insulin resistance. It can reduce the BMI, body fat percentage, blood lipids, blood glucose, and serum insulin levels and improve insulin resistance. The action may be associated with the up-regulation of serum PYY and nesfatin-1.
