Cell death is a fundamental phenomenon for organisms to maintain their basic morphology.When a pathogen infects a cell,the process of programmed cell death is activated,the lysed cells carrying the pathogen ac-tivate the immune response of the organism in the process of removing infected cells,thus exerting immune de-fense.The molecular mechanisms of the 4 types of cell death modes apoptosis,pyroptosis,necroptosis and pan-apoptosis as well as their effects on innate immune defense against microbial infections were mainly elaborated in the article,the interactions among the different programmed cell death pathways were briefly interpreted so as to provide new ideas for further study of pathogenic mechanisms of infectious diseases.

Objective To investigate the action mechanism of Bufei Yiqi Tongluo formula in treating id-iopathic pulmonary fibrosis (IPF) based on the transforming growth factor-β1 (TGF-β1)/c-Jun N-terminal ki-nase (JNK) signaling pathway.Methods The key targets of network pharmacology conducted the enrichment analysis and the IPF rat model was constructed,which was divided into the blank control group,IPF model group and Bufei Yiqi Tongluo formula group.The pathological changes of lung tissue in various groups were observed,and the levels of white blood cells (WBC) in bronchoalveolar lavage fluid (BALF) were analyzed. The enzyme-linked immunosorbent assay (ELISA) was used to detect the protein expression levels of tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6),phosphorylated JNK (p-JNK)/JNK,TGF-β1,tissue inhibitor of metalloproteinases-1 (TIMP-1) and matrix metalloproteinase-9 (MMP-9) in serum,BALF and lung tissue. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the mRNA expression levels of these proteins in serum,BALF and lung tissue.Results The network pharmacology enrichment analysis re-sults revealed that TGF-β1 and JNK signaling pathways were closely related with IPF.Compared with the IPF model group,the lung tissue orderliness in the Bufei Yiqi Tongluo formula group was increased,the consolida-tion range was decreased,the fibrotic tissue proliferation was significantly reduced,the WBC level and expres-sion levels of TNF-α and IL-6 in BALF were significantly decreased.Compared with the blank control group,the mRNA expression levels of TGF-β1,p-JNK/JNK,TIMP-1 and MMP-9 in serum,BALF and lung tissues in the IPF model group were increased with statistical difference (P<0.05).After the intervention on the model rats by the Bufei Yiqi Tongluo formula,except there was no difference in the expression level of MMP-9 pro-tein in serum,TGF-β1 in BALF,TIMP-1 in serum and MMP-9 mRNA in lung tissue,but the other indicators were decreased (P<0.05).Conclusion The therapeutic effect of Bufei Yiqi Tongluo formula in IPF may be related to its regulation on the TGF-β1/JNK signaling pathway.

Objective To assess the methodology,reporting quality and intervention reporting quality of randomised controlled trials(RCT)of acupuncture for chronic obstructive pulmonary disease(COPD).Methods Randomized controlled trials of acupuncture for the treatment of chronic obstructive pulmonary disease from the establishment of the database to March 1,2023 through computer system search of CNKI,Wanfang,VIP,SinoMed,and PubMed databases.Two researchers independently conducted literature search,relevant data extraction,etc.,and assessed the quality of reports using the bias assessment tools ROB2,CONSORT Extended Statement and STRICTA List of Cochrane Systematic Review Manuals.Results After excluding non-compliant articles through the developed exclusion criteria,31 RCT remained.A methodological assessment of the included RCT according to the Cochrane website bias assessment tool ROB2 showed that 9 studies(29.03%)were at high risk of bias and no studies at low risk of bias.The CONSORT extended statement based on non-drug randomized controlled trials evaluated the quality of the literature,indicating that the reporting rate in terms of methods,results,trial protocol registration,etc.was low.The results of the evaluation according to the entries in the STRICTA list show that most of the literature does not describe the details of acupuncture and the background of the therapist in sufficient detail,but the reasonableness of acupuncture treatment is relatively complete.Conclusion At present,the quality of randomized controlled trials of acupuncture for COPD is generally low,and it is recommended that future researchers strictly follow the internationally recognized CONSORT statement and STRICTA list for trial protocol design and study result reporting.
