Objective: To study the effect of aerobic exercise training on insulin resistance, lipid metabolism and inflammatory response in patients with Alzheimer’s disease (AD). Methods: A total of 84 patients who were diagnosed with Alzheimer’s disease in the Mental Health Center in Zigong City between June 2014 and December 2016 were selected and randomly divided into aerobic exercise group and normal control group who received aerobic exercise intervention combined with conventional drug therapy and conventional drug therapy respectively. The insulin resistance indexes, blood lipid metabolism indexes and inflammatory response indicators were detected before intervention as well as 3 months and 6 months after intervention. Results: 3 months and 6 months after intervention, the HOMA-IR levels as well as serum TC, LDL-C, ApoB, TNF-α, MCP-1, MIA-1α and HMGB1 contents of aerobic exercise group were significantly lower than those before intervention while HOMA-β, ISIcomp and MBCI levels as well as serum HDL-C and ApoAI contents were significantly higher than those before intervention; the HOMA-IR, HOMA-β, ISIcomp and MBCI levels as well as serum TC, LDL-C, HDL-C, ApoAI, ApoB, TNF-α, MCP-1, MIA-1α and HMGB1 contents of normal control group were not statistically different from those before intervention. Conclusion: Aerobic exercise training can improve insulin resistance and blood lipid metabolism, and inhibit inflammatory response in patients with AD.

Objective Mutations in polymerase gamma gene (POLG) are believed to be an important cause of early and juvenile onset of non-syndromic intractable epilepsy. The aim of this study is to investigate the incidence/prevalence of POLG pathogenic variants in epilespy patients of Han population through sequencing it.Methods Han Chinese patients with seizures prior valproic acid (VPA) exposure at Shanghai Children's Hospital were collected from 2015 to 2019. The clinical diagnosis was based on the 2014 Consensus Statement of Epilepsy by the International League against Epilepsy (ILAE). Blood sampling were performed before VPA treatment. The POLG gene DNA was sequenced by either the first or the next generation sequencing (NGS). The POLG variant burden was illustrated. Liver functions were tested to describe whether they experienced VPA toxicity.Results Totally 216 Han Chinese patients were included, aged from 1 month to 15 years old, 102 were male and 114 were female. The onset age was 1 month old to 13 years old, and the epilepsy course ranged from 2 weeks to about 3 years. VPA treatment was delivered for the generalized or intractable partial seizures at standard dosage. No patient experienced hepatic toxicity following VPA exposure. DNA sequencing data showed no patient had either a homozygous mutation or compound heterozygous mutation of POLG. Single heterozygous mutations of c.1150G>T and p.D384Y were found in 2 patients, and single heterozygous mutation of c.156_158dupGCA was found in 1 patient. None of these variants showed clinical significance.Conclusions Functional modifying POLG homozygous mutations and compound heterozygous mutations were not detected and VPA toxicity was not seen in the current study. POLG mutation frequency might be rare in Han Chinese, and standard VPA therapeutic dosage might be safe for Han Chinese patients.
