Objective To study the effects of monomers in Lagotis brachystachya Maxim including quercetin,echinacoside,and apigenin on the p38MAPK/JNK,TLR4/MyD88/NF-κB,and NLRP3 signaling through establishing a rat model of chronic alcoholic liver injury combined with gouty arthritis,and to explore the mechanism of the above-mentioned monomers in the treatment of chronic alcoholic liver injury combined with gouty arthritis.Methods Eighty rats were randomly divided into normal group,model group,bifendate group(100 mg·kg-1),colchicine group(0.3 mg·kg-1),and different dose groups of quercetin(50,25 mg·kg-1),echinacoside(50,25 mg·kg-1),and apigenin(50,25 mg·kg-1).The rats were administered at a dose of 10 mL·kg-1 per day in the morning and administered with 56-degree Red Star Erguotou at a dose of 4 mL·kg-1 in the afternoon,with gradual increasement of 2 mL·kg-1 per week until a final dose of 10 mL·kg-1.The rats were continuously fed by gavage for 8 weeks.Gouty arthritis model was induced at the 53th day of alcohol-based feeding.Toe volume was measured at difference time.At the end of the 8th week,blood was collected after the last administration.Serum alanine aminotransferase(ALT),aspartate aminotransferase(AST),alkaline phosphatase(ALP)levels,total cholesterol(TC)and triglycerides(TG)were measured.Enzyme-Linked Immunosorbent Assay(ELISA)was used to detect interleukin-1β(IL-1β)in rat serum.Western Blot was used to detect the expression of p38 mitogen-activated protein kinase(p38MAPK),phosphorylated p38MAPK(p-p38MAPK),c-Jun N-terminal kinase(JNK),phosphorylated JNK(p-JNK),Toll-like receptor 4(TLR4),myeloid differentiation factor 88(MyD88),nuclear factor-κB(NF-κB),phosphorylated NF-κB(p-NF-κB),and NOD-like receptor protein domain containing 3(NLRP3)in liver and synovial tissues.Results Compared with the normal group,the toe swelling degree in the model group was significantly increased at difference time(P<0.05,P<0.01).The levels of ALT,AST,ALP,TC,TG,and IL-1β in serum were significantly increased(P<0.01).The protein expression levels of p-p38MAPK,p-JNK,MyD88,p-NF-κB,TLR4,and NLRP3 in liver and synovial tissues were all increased to varying degrees(P<0.01).Compared with the model group,the toe swelling degree in all treatment groups significantly decreased after 24 hours(P<0.01).The levels of ALT and TC in the bifendate group and different dose groups of monomers decreased to varying degrees(P<0.05,P<0.01).Except for the low dose group of echinacoside,the levels of AST and ALP in other treatment groups decreased to varying degrees(P<0.01).Except for the high dose group of quercetin,the levels of TG in other treatment groups decreased to varying degrees(P<0.01).The protein expression levels of p-p38MAPK,p-JNK,MyD88,p-NF-κB,TLR4,and NLRP3 in liver and synovial tissues of rats in all treatment groups were down-regulated(P<0.05,P<0.01).Conclusion The monomers in Lagotis brachystachya Maxim show certain therapeutic effects of treating different diseases with same treatment on the rat model of chronic alcoholic liver injury combined with gouty arthritis,and their therapeutic effects may be mediated through p38MAPK/JNK,TLR4/MyD88/NF-κB,and NLRP3 signaling pathways.

OBJECTIVE: To investigate the subjective symptoms of eyes induced by laser radiation in workers and its related influencing factors. METHODS: A total of 82 workers exposed to laser radiation were taken as exposure group, and 71 workers without laser radiation exposure as control group by judgment sampling method. The questionnaire survey and subjective symptoms of eyes were surveyed in these two groups. The work-site surveys of laser radiation job posts and laser irradiation testing were conducted to evaluate the exposure level of laser radiation on each post. The basic eye use and eye discomfort symptoms were investigated. RESULTS: The median of the laser radiation in 12 workplaces was 2.18×10~(-5) W/cm~2, and it was below occupational exposure limit(2.22×10~(-3) W/cm~2). The total detection rate of subjective discomfort of eyes in the exposed group was significantly higher than that in the control group(35.4% vs 15.5%, P<0.05). The results of multivariate logistic regression analysis indicated that laser exposure and smoking were the risk factors of subjective symptoms of eyes(P<0.05). CONCLUSION: Laser radiation operation has the risk of causing the subjective symptoms of eyes in exposed workers.

Objective To analyze the expression and clinical treatment and prognosis assessment significance of FAM83H-AS1 in breast cancer by bioinformatics analysis.Methods The expression of FAM83H-AS1 in various cancer types was analyzed in the Cancer Genome Atlas(TCGA)database by R language.Additionally the expression in breast cancer was examined by Gene Expression Profiling Interactive Analysis(GEPIA)online database.Survival data were downloaded from TCGA to analyze the correlation between FAM83H-AS1 expression levels and prognosis among breast cancer patients.GEPIA and Kaplan-Meier Plotter were used for dual verification.Clinical information was obtained from TCGA for further analysis on the relationship between FAM83H-AS1 and clinical characteristics.And the relationship between FAM83H-AS1 and tumor microenvironment,immunodetection point-related genes and tumor mutation burden(TMB)was analyzed using R language.Gene set enrichment analysis(GSEA)was performed.Results The expression of FAM83H-AS1 was abnormal in many cancers,particularly exhibiting a significant increase in breast cancer.High expression of FAM83H-AS1 is associated with significantly reduced overall survival in breast cancer patients.Furthermore,the expression level of FAM83H-AS1 varies among breast cancer patients with different clinical stages.FAM83H-AS1 exhibits negative correlation with stromal cell score and immune cell score in breast cancer samples,and correlated with immune detection point-related gene.TMB radar map results suggest that the expression of FAM83H-AS1 in breast cancer is positively correlated with tumor mutational burden.GSEA revealed a positive correlation between the expression of FAM83H-AS1 and the function of mismatch repair.Conclusion FAM83H-AS1 is highly expressed in breast cancer,and is related to poor prognosis.Its expression correlates with clinicopathological stage,tumor microenvironment and TMB of breast cancer patients.Furthermore,FAM83H-AS1 exhibits associations with certain immune checkpoint-related genes and mismatch repair genes.These findings provide a important theoretical basis for clinical treatment,prognosis prediction and development of gene-target drugs.
