It is very limited that the benefit of perioperative chemotherapy in early non-small cell lung cancer (NSCLC), and the 5-year survival rate is only 5% higher than surgery. Antibodies that block programmed cell death protein 1/programmed death-ligand 1 significantly improve the survival of advanced NSCLC. The value of immunotherapy in early NSCLC is also being explored. This paper firstly summarized and analyzed the progress of immunotherapy in the perioperative period of NSCLC. Secondly, the safety and feasibility of surgical resection after neoadjuvant immunotherapy were discussed. Finally, the clinical value of different therapeutic efficacy prediction indicators was summarized, in order to clarify the current status of immunotherapy in the perioperative period, so as to improve the clinical benefits of early NSCLC patients.

AIM:To investigate the therapeutic effects and potential mechanism of pachymic acid(PA)on li-popolysaccharide(LPS)-induced acute kidney injury(AKI)in mice.METHODS:(1)Genes related to AKI were screened using the DAVID database.Core genes were identified by intersecting related genes and analyzed using Cyto-scape software.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analyses were performed through the DAVID database for the cross-targets.Molecular docking and activity assays were conducted on the primary core targets.(2)A total of 100 C57BL/6J mice were randomly divided into five groups:normal control(NC),model(LPS),solvent control(LPS+DMSO),and treatment groups(LPS+PA-10 and LPS+PA-20),with 20 mice in each group.The LPS-AKI model was established by intraperitoneal injection of 18 mg/kg LPS.The treatment groups received 10 mg/kg and 20 mg/kg PA,respectively,and the solvent control group was administered an equivalent dose of DMSO.Mice were euthanized 24 h after injection.Serum was collected for biochemical analysis,and Western blot was used to detect neutro-phil gelatinase-associated lipocalin(NGAL),kidney injury molecule-1(KIM-1),caspase-3,cleaved caspase-3,interleu-kin-1β(IL-1β),and monocyte chemoattractant protein-1(MCP-1)protein expression.RT-qPCR was employed to detect inflammatory factor mRNA levels.Molecular docking was used to simulate the optimal binding site of PA to caspase-3.En-zyme activity assays were performed to assess caspase protein activity,and renal lesions were observed via hematoxylin and eosin(HE)staining.Apoptosis was detected by TUNEL staining.RESULTS:(1)Thirty-one potential targets of PA against AKI were identified through network pharmacology.GO and KEGG enrichment analyses indicated that these tar-gets were primarily involved in immune response,inflammatory processes,apoptosis and survival,angiogenesis and hemo-dynamics,oxidative stress,and endoplasmic reticulum stress.Key targets included CASP3(caspase-3),PTGS2,BCL2,CCL2,and CYP219.(2)PA treatment improved renal function and reduced tubular epithelial injury.It significantly de-creased NGAL,KIM-1,and cleaved caspase-3 protein levels,as well as inflammatory factors TNF-α,IL-1β,and MCP-1 mRNA and protein expression.PA also reduced apoptosis of renal tubular epithelial cells.Enzyme activity assays and mo-lecular docking revealed that PA exerted its anti-apoptotic effect by directly binding to caspase-3,thereby inhibiting its ac-tivation by caspase-8.CONCLUSION:PA demonstrated a therapeutic effect in LPS-AKI,potentially through the inhibi-tion of inflammatory factor synthesis and release,as well as the inhibition of caspase-3 activation by caspase-8,reducing apoptosis in renal tubular epithelial cells.

Objective :
To explore the relationship between single nucleotide polymorphisms ( SNPs) in D-loop region of mitochondrial DNA ( mtDNA) and mtDNA copy number and the risk of dermatomyositis ( DM) ,and its in- fluencing factors.
Methods :
74 patients with DM and 92 healthy controls were included in the study. Genomic DNA was extracted from peripheral blood and the target fragment of mtDNA D-loop region was amplified by PCR technique,and the products were subsequently sequenced.Serum levels of ROS were assessed using a high-sensi- tivity reactive oxygen species detection kit.The expression levels of cytokines,interleukin ( IL) -5,IL-13,inter- feron-γ ( IFN-γ) ,IL-2,IL-6,IL-10,tumor necrosis factor-α ( TNF-α) and IL-4 were measured using Flow Fluo- rescence Immunmicrobeads Assay.Wilcoxon rank-sum test was used to assess the potential correlation between cy- tokines and SNPs associated with DM risk.The relative copy number of mtDNA was measured using quantitative re- al-time polymerase chain reaction ( qPCR) analysis.
Results :
Two SNPs ( 16304T / C,16519T / C) were found to be associated with the risk of developing DM,and alleles 16304C ( χ2 = 4. 937,P = 0. 026) and 16519C ( χ2 = 4. 405,P = 0. 036) in the mitochondrial D-loop region were confirmed to be associated with DM development risk. The DM risk-associated allele 16304C was significantly associated with lower IL-4 expression ( P = 0. 016) .The mtDNA copy number was significantly higher in DM patients than in controls ( P <0. 001) .
Conclusion
Mitochondrial D-loop SNPs can be potential biomarkers for DM risk,and SNPs may be involved in DM by influencing cytokines.DM shows high expression of mtDNA copy number,and the increase in mtDNA copy number may lead to mitochondrial dysfunction,which triggers the pathogenesis of DM.
