Acute pancreatitis (AP) is a life-threatening gastrointestinal disorder for which no effective pharmacological treatments are currently available. One of the pharmacological targets that merits further research is the neurokinin 1 receptor (NK1R), which is found on pancreatic acinar cells and responds to the neuropeptide substance P (SP) that participates in AP. Although a few studies have stated the involvement of SP/NK1R in neurogenic inflammation in AP development, the regulatory mechanism remains unclear. In this study, we found that following activation of NK1R by SP, β-arrestin1, a scaffold protein of NK1R, down-regulated transcription of Adss, Adsl, and Ampd in the purine nucleotide cycle, thereby inhibiting mitochondrial function through fumarate depletion. Interestingly, we identified magnolol as a new and natural NK1R inhibitor with a non-nitrogenous biphenyl core structure. It exhibited a beneficial effect on AP by restoring purine nucleotide cycle metabolic enzymes and fumarate levels. Our study not only provides new therapeutic strategies, leading compounds, and drug translation possibilities for AP, but also provides important clues for the study of downstream mechanisms driven by SP in other diseases.

ObjectiveTo investigate the correlation of polymorphism and loci interaction of nucleic acid binding oligomeric domain-like receptor heat protein domain associated protein 3 (NLRP3) gene and susceptibility to coal workers' pneumoconiosis (CWP) in Xinjiang Region. Methods A total of 109 CWP were selected as the case group, and 69 coal miners with similar age, years of dust exposure and work types were selected as the control group by convenient sampling method. Blood samples of individuals in workers in these two groups were collected, and the genotypes of single nucleotide polymorphism loci, rs1539019, rs4612666, rs4925650 and rs7525979, in the NLRP3 gene were detected using an improved multiplex ligation detection reaction. The optimal genetic model was selected based on the Akaike information criterion. Results The results of unconditional logistic regression analysis showed that individuals with the C allele of rs1539019 or rs4612666 had a higher risk of CWP than those with the A or T allele (all P<0.05), and individuals with the AA genotype of rs1539019 or the TT genotype of rs4612666 had a lower risk of CWP than those with the CC genotype (all P<0.05), after adjusting for age, years of work, alcohol, and smoking. The optimal genetic models for rs1539019 and rs4612666 were the recessive model and the additive model, respectively, and these differences were associated with the susceptibility to CWP at the Bonferroni-corrected level (all P<0.05). No correlation was found between rs4925650 and rs7525979 and the susceptibility to CWP (all P>0.05). In the smoking population, the rs1539019 co-dominant model, recessive model, and additive model were associated with a decreased risk of CWP (all P<0.05). The rs4612666 co-dominant model, dominant model and additive model were associated with an increased risk of CWP (all P<0.05), with the optimal genetic models being the recessive model and the additive model among smokers. The rs1539019 and rs4612666 were not found to be associated with the increased risk of CWP in non-smokers (all P>0.05). The rs4612666 dominant model and additive model were associated with an increased risk of CWP (all P<0.05), and the rs4925650 recessive model and over-dominant model were associated with a decreased and increased risk of developing CWP (all P<0.05), with the optimal genetic models being the dominant model and the over-dominant model in drinkers. The rs1539019 co-dominant model, dominant model, recessive model, and additive model were associated with a decreased risk of developing CWP (all P<0.05), and the rs4612666 co-dominant model, recessive model, and additive model were associated with an increased risk of developing CWP (all P<0.05), with the optimal genetic models being the additive model and the recessive model in non-drinkers. The result of haplotype analysis showed that the ACAC and ACGC haplotypes were associated with a reduced risk of CWP (all P<0.05). Conclusion The rs1539019 and rs4612666 loci of the NLRP3 gene are associated with susceptibility to CWP. This study provides clues for further research on the risk of CWP in coal workers.

Objective To investigate the mechanism by which mycobacterial antigen 85B (Ag85B) inhibits autophagy and promotes apoptosis in Hodgkin lymphoma (HL) cells. Methods The clinical data and pathological tissue slides were retrospectively collected from 80 HL children and 30 children with reactive lymphadenopathy (control group) treated at the First Affiliated Hospital of Xinjiang Medical University. Immunohistochemical analysis was performed to assess the expression of microtubule-associated protein 1 light chain 3 (LC3),sequestosome 1 (P62/SQSTM1),and Beclin-1 in the pathological tissues of HL and control groups. Human Hodgkin lymphoma cells (HDLM-2) were divided into the HDLM-2 group and the HDLM-2+Ag85B groups (with Ag85B concentrations of 0.5,1,2,and 4 μg/mL). The CCK8 method was used to measure HDLM-2 cell proliferation;qRT-PCR was employed to detect the expression of LC3,P62,Beclin-1,Akt,and mTOR mRNA in cells. An apoptosis kit was used to detect cell apoptosis. Results The positive expression of LC3 and Beclin-1 in the HL group were higher than those in the control group (P<0.05),while the positive expression of P62 was lower than that in the control group (P<0.05). In stages Ⅲ-Ⅳ compared to stages Ⅰ-Ⅱ,the positive expression of LC3 and Beclin-1 increased,while the positive expression of P62 decreased (P<0.05). Cell experiment results showed that the HDLM-2+Ag85B group had suppressed cell proliferation compared to the HDLM-2 group,with decreased mRNA expression of LC3 and Beclin-1,and increased mRNA expression of P62,PI3K,Akt,and mTOR,leading to increased cell apoptosis. Notably,when Ag85B was at a concentration of 2 μg/mL,it had the strongest effect on HDLM-2 cells after 24 hours (P<0.05). Conclusions Autophagy is enhanced in children with HL and increases with disease stage. Ag85B can inhibit the proliferation and autophagy of HL tumor cells and promote apoptosis,possibly related to the activation of the PI3K/Akt/mTOR pathway.
