Objective: Psoriasis is associated with a high prevalence of metabolic syndrome (MS), and patients with concomitant psoriasis and MS are more severely affected and less responsive to treatment. However, the molecular mechanisms behind these effects are unknown. Recent studies have shown that leptin may serve as a molecular link between psoriasis and MS, suggesting that high leptin concentrations may exacerbate psoriasis. However, the molecular mechanism of this effect is still unclear. We aimed to investigate the effect of leptin on autophagy in patients with psoriasis. Methods: From January 2021 to June 2022 in PLA general hospital, we enrolled 51 patients with psoriasis, including 21 patients with MS and 30 without MS, and 30 healthy controls who had undergone nevus surgery. We measured the epidermal leptin, P62, and LC3B concentrations of patients by immunohistochemistry, and measured the serum leptin concentration by enzyme-linked immunosorbent assay. We then performed correlation analyses to compare these proteins' concentrations between patients with concomitant psoriasis and MS, patients with psoriasis alone, and healthy control groups. Additionally, we performed western blotting after in vitro culture of HaCaT cells with different concentrations of leptin and measured the expression levels of the autophagy markers Beclin1, LC3B, and P62; the differentiation markers K10, K16, and K17; and PI3K/AKT/mTOR signaling pathway-related proteins of HaCat cells. Next, we transfected ATG5 into HaCaT cells to revert autophagy and used the specific PI3K inhibitor LY294002 to block PI3K/AKT/mTOR signaling. The expression levels of K10, K16, and K17 of HaCat cells were again measured. One-way analysis of variance was used for the comparison of means of multiple samples, and LSD-t post hoc test was used for comparison between the 2 groups. The counting data were analyzed by the chi-square test. Correlations were evaluated by Pearson correlation analysis. Results: The serum l

Chlorfenapyr is a liposoluble insecticide belonging to the pyrrole *** is activated when the N-ethoxymethyl side chain breaks,forming a toxic metabolite,which uncouples oxidative phosphorylation in the mitochondria,inhibits the production of adenosine triphosphate (ATP),and leads to the death of cells and targe organisms.[1] Symptoms of chlorfenapyr poisoning in patients are mild and atypical in the early stage,especially in patients receiving low dose exposure;however,such cases are rare and may be ignored by physicians,often leading to delayed treatment.[2,3].
