Parkinson's disease(PD)is the second most prevalent neurodegenerative disease and a major cause of movement disorders.Neuroinflammation plays an important role in the pathogenesis of PD.Icilin is a small molecule compound that has been reported to inhibit inflammation.Howev-er,its role in PD has not been reported.This study explored the effects of icilin on motor behavior,nerve damage,microglia activation,and neuroinflammation in MPTP-induced PD Meriones unguic-ulatus by behavioral experiments,immunohistochemistry,Western blot,and fluorescence quantifi-cation.The results showed that Icilin not only ameliorated motor dysfunction and neurological damage in MPTP-induced Meriones unguiculatus,but also inhibited microglia hyperactivation and its mediated neuroinflammation.The present study provides an evidence that icilin attenuates MPTP-induced neurodegenerative lesions in long-pawed gerbils,suggesting that it is a promising candidate for PD.

Objective To study the damage effect of high-voltage electric shock on skin based on metabolomics,analyze its metabolic differences,and explore its injury mechanism.Methods A total of 16 SPF C57BL/6J male mice were divided into the electric shock group(head skin received electric shock treatment)and control group(head skin received electric shock acoustic-optical stimulation),and the skin appearance after treatment of mice in the two groups was observed.The histopathological changes caused by electric shock were analyzed by HE staining,EVG staining and Masson staining.GC-MS and LC-MS metabonomics were used to analyze the changes of skin metabolism spectrum and tissue metabolites after electric shock exposure,and the differential metabolites were analyzed.The obtained differential metabolites were combined and KEGG enrichment analysis was conducted.Results After high-voltage electric shock,the skin of mice could be damaged to the dermis,and the epidermis was partially thickened,lifted and separated.The structure of skin appendages in the dermis was destroyed,with a large number of inflammatory cells infiltrating and obvious swelling,accompanied by congestion,which led to severe skin inflammatory reaction and impaired skin barrier function.Metabonomics analysis suggested that the metabolites changed after electric shock exposure.KEGG enrichment analysis showed that electric shock significantly affected the central carbon metabolism pathway of cancer,pentose phosphate pathway,purine metabolism,glycine,serine and threonine metabolism processes,amino acid tRNA biosynthesis mechanism,glycerophospholipid metabolism pathway,pyrimidine metabolism pattern,glycolysis/gluconeogenesis,alanine metabolism process,glucagon signal pathway and so on.Conclusion High voltage electric shock can cause deep skin damage,disturb its energy metabolism and amino acid metabolism,and seriously interfere with its antioxidant and DNA repair system functions.

ObjectiveTo analyse the efficacy and mechanism of Guizhi Fulingwan in regulating sex hormone disorders in rats with benign prostatic hyperplasia (BPH). MethodsThirty male SD rats were randomly divided into a sham group, a model group, a finasteride group (0.45 mg·kg-1·d-1), and low-dose and high-dose groups of Guizhi Fulingwan (0.135, 0.337 5 g∙kg-1∙d-1), with six in each group. The BPH model was prepared by subcutaneous injection of 3.5 mg∙kg-1∙d-1 testosterone propionate after debridement surgery in all groups except the sham group. The rats in the sham group and the model group were administered with an equal volume of saline by gavage, and the rest of the groups were administered with the corresponding medicinal solution by gavage for 35 days. Histopathology in rats was evaluated by prostate wet weight, volume, index, and hematoxylin-eosin (HE) staining. The serum sex hormone levels of testosterone (T), dihydrotestosterone (DHT), and estradiol (E2) were determined by enzyme-linked immunosorbent assay. The protein expression of the androgen receptor (AR) was detected by immunohistochemistry. The serum metabolism profiles of rats in the sham group, the model group, and the high-dose group of Guizhi Fulingwan were compared by ultra-high performance liquid chromatography tandem Fourier transform mass spectrometry (UHPLCQ Exactive) to screen for metabolic markers and to obtain relevant metabolic pathways. ResultsCompared with those in the sham group, the wet weight, volume, index, serum sex hormone level, and AR protein expression of the prostate in the model group were all elevated (P<0.05, P<0.01), and the histomorphology showed pathological changes. Compared with those in the model group, the wet weight, volume, index, serum sex hormone level, and AR protein expression of the prostate in the intervention groups showed a decreasing trend (P<0.05, P<0.01), and histopathology was improved. Serum metabolomics analysis obtained a total of 40 metabolic markers related to the intervention effect of Guizhi Fulingwan, such as dehydrosafynol, hyoscyamine, and lumichrome, which were involved in the pathways of autophagy, riboflavin metabolism, and retrograde endocannabinoid signaling. ConclusionGuizhi Fulingwan can effectively regulate sex hormone disorders in BPH rats, and its mechanism may be related to autophagy, riboflavin metabolism, and retrograde endocannabinoid signaling.

This study aims to explore the intervention effects of isorhamnetin(Isor) on acute lung injury(ALI) and its regulatory effects on pyroptosis mediated by the NOD-like receptor family pyrin domain containing 3(NLRP3)/apoptosis-associated speck-like protein containing a CARD(ASC)/cysteine aspartate-specific protease-1(caspase-1) axis. In the in vivo experiments, 60 BALB/c mice were divided into five groups. Except for the control group, the other groups were administered Isor by gavage 1 hour before intratracheal instillation of LPS to induce ALI, and tissues were collected after 12 hours. In the in vitro experiments, RAW264.7 cells were divided into five groups. Except for the control group, the other groups were pretreated with Isor for 2 hours before LPS stimulation and subsequent assessments. Hematoxylin-eosin(HE) staining was used to observe pathological changes in lung tissue, while lung swelling, protein levels in bronchoalveolar lavage fluid(BALF), and myeloperoxidase(MPO) levels in lung tissue were measured. Cell proliferation toxicity and viability were assessed using the cell counting kit-8(CCK-8) method. Enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of interleukin-1β(IL-1β), IL-6, IL-18, and tumor necrosis factor-α(TNF-α). Protein levels of NLRP3, ASC, cleaved caspase-1, and the N-terminal fragment of gasdermin D(GSDMD-N) were evaluated using immunohistochemistry, immunofluorescence, and Western blot. The results showed that in the in vivo experiments, Isor significantly improved pathological damage in lung tissue, reduced lung swelling, protein levels in BALF, MPO levels in lung tissue, and levels of inflammatory cytokines such as IL-1β, IL-6, IL-18, and TNF-α, and inhibited the high expression of the NLRP3/ASC/caspase-1 axis and the pyroptosis core gene GSDMD-N. In the in vitro experiments, the safe dose of Isor was determined through cell proliferation toxicity assays. Isor reduced cell death and inhibited the expression levels of the NLRP3/ASC/caspase-1 axis, GSDMD-N, and inflammatory cytokines. In conclusion, Isor may alleviate ALI by modulating pyroptosis mediated by the NLRP3/ASC/caspase-1 axis.
