Chronic stress triggers the imbalance of the homeostasis of the tumor immune microenvironment(TIME),which is a key factor driving the development of lung cancer.Based on the mapping relationship between the concept of"spirit"in traditional Chinese medicine and chronic stress,and between"qi"and"immunity",it is believed that the cross-linking mechanism of"chronic stress-TIME-lung cancer"aligns with the understanding of traditional Chinese medicine of disease as involving the interplay between the"body,qi and spirit".The disorganization of"spirit"and"qi"is not only the root of the change of the"form",but also the key to prevent and control it.The treatment principle of synergizing to improve the chronic stress of"regulating the spirit"and remodeling the TIME of"invigorating the qi"is further proposed,which emphasizes on grasping the core pathogenesis of lung cancer at each stage of its evolution in order to administer medicines,drawing on the clinical experience and pharmacological research results in order to accurately hit the target,and combining special therapies like acupuncture,Chinese kungfu,sound therapy to treat the change of"shape"by modulating neuro-endocrine-immune network homeostasis,so as to provide new ideas and accessible solutions for the comprehensive prevention and treatment system of lung cancer.

Sheep and goats are important tuberculosis hosts found predominantly in plateau and mountainous regions.In recent years,the number of reported tuberculosis cases in sheep and goats has increased.The tuberculosis pathogen can spread among vari-ous animal species and even infect humans,thus further complicating disease prevention and control,and posing a serious threat to the health of both humans and livestock.This article summarizes the global prevalence of tuberculosis in sheep and goats,and specifi-cally analyzes the epidemic status in China.Frequently used tuberculosis detection methods in sheep and goats are described,and the shortcomings of each method are briefly introduced.Additionally,on the basis of frequently applied methods for monitoring,handling,and controlling tuberculosis in sheep and goats worldwide,suggestions are offered to provide a reference for tuberculosis control in sheep and goats in China.

This study was aimed at investigating the immunoregulatory function of Mycobacterium tuberculosis Rv3641c gene in modulating host type Ⅰ interferon responses.The shuttle plasmid pMV261 was used to construct Rv3641c overexpression recombinant Mycobacterium smegmatis,and the biological characteristics of the recombinant bacteria were analyzed to explore the effect of Rv3641c on the growth curve,colony morphology and stress resistance of Mycobacterium.Subsequently,RAW264.7 cells were infected with Rv3641c overexpressing Mycobacterium smegmatis,and the transcriptional expression of genes related to the inhibition of type I inter-feron pathway was determined by RT-PCR.The expression level of IFN-βprotein was determined by ELISA,and the intracellular sur-vival level was determined.As a result,the recombinant rMS::pMV261-Rv3641c was successfully constructed.The results of biologi-cal characteristics analysis showed that Rv3641c did not affect the growth of mycobacteria,but significantly changed the colony mor-phology of mycobacteria and improved its resistance to H2O2.The results of recombinant bacteria infection experiments showed that Rv3641c significantly down-regulated the transcription levels of IFN-α,IFN-βand downstream ISGs genes CXCL10,IFIT2 and IL-1β in host cells,and Rv3641c significantly down-regulated the transcription levels of IFN-α,IFN-βand downstream ISGs genes CXCL10,IFIT2 and IL-1βin host cells.The results of intracellular colonization experiments showed that the intracellular mycobacte-ria in the overexpression recombinant bacteria infection group were significantly higher than those in the empty vector group,indicat-ing that Rv3641c could promote the intracellular surviv al of mycobacteria.In summary,the Rv3641c gene of M.tuberculosis can inhibit the host type I interferon response and promote the intracellular survival of M.tuberculosis,which provides a new idea for further explor-ing the immune escape function of M.tuberculosis and the discovery of new targets for anti-tuberculosis drugs.

Objective:To investigate the efficacy and safety of bridging thrombectomy and direct thrombectomy in patients with acute anterior circulation large core infarction.Methods:A retrospective cross-sectional study was performed; 131 patients with acute anterior circulation large core infarction with an onset time≤ 24 hours received endovascular treatment (EVT) at Department of Intervention Neurosurgery, Nanyang Central Hospital, Xinxiang Medical University, from June 2022 to June 2024 were chosen; they were divided into bridging thrombectomy group (accepted intravenous thrombolysis [IVT] before EVT, n=55) and direct thrombectomy group ( n=76). Statistical analysis was conducted to compare the differences in efficacy and safety between the two groups. Efficacy indicators included modified Rankin scale (mRS) score 90 days after thrombectomy, and good prognosis rate 90 days after thrombectomy (mRS scores of 0-2). Safety indicators included intracranial hemorrhage (ICH) incidence within 72 hours of thrombectomy, symptomatic intracranial hemorrhage (sICH) incidence within 72 hours of thrombectomy, mortality 90 days after thrombectomy, and ratio of patients receiving decompressive craniectomy after surgery. Results:No significant difference between the direct thrombectomy group and bridging thrombectomy group was noted in terms of mRS score 90 days after thrombectomy (3 [2, 6] vs. 3 [2, 6]), good prognosis rate 90 days after thrombectomy (38.2% vs. 25.5%), ICH incidence within 72 hours of thrombectomy (30.3% vs. 40.0%), sICH incidence within 72 hours of thrombectomy (21.1% vs. 21.8%), mortality rate within 90 days of thrombectomy (28.9% vs. 25.5%), and ratio of patients receiving decompressive craniectomy after surgery (9.2% vs. 9.1%, P>0.05). Core infarction volume at 100 mL was used as grouping standard, subgroup analysis showed that when the core infarction volume was 70-100 mL and >100 mL, respectively, no significant difference in sICH incidence was noted between the bridging thrombectomy group and direct thrombectomy group ( P>0.05). Conclusion:For patients with acute anterior circulation large core infarction with an onset time≤ 24 hours, bridging thrombectomy has similar efficacy and safety as direct thrombectomy.

Plant polysaccharides are effective components that widely present in traditional Chinese medicine(TCM), exhibiting rich biological activities. However, as most plant polysaccharides cannot be directly absorbed and utilized by the human digestive system, it is now believed that their mode of action mainly involves interaction with intestinal microbiota, leading to the production of functional small molecules. The efficacy of Astragalus polysaccharide(APS) is extensive, including weight loss, improvement of fatty liver, reduction of blood lipids, and enhancement of insulin sensitivity, which may also be related to the regulation of intestinal microbiota. Adipose tissue senescence is an important characteristic of the physiological aging process in the body, often occurring prior to the aging of other important organs. Its main features include the accumulation of senescent cells and exacerbation of inflammation within the tissue. Therefore, to explore the potential protective effects of APS on aging, the improvement of adipose tissue aging phenotype in naturally aging mice was observed using APS, and combined with metagenomic metabolomics, corresponding microbial metabolic functional molecules were identified. Furthermore, functional tests in cell aging models were conducted. The results showed that APS significantly improved the adipocyte aging characteristics of naturally aging mice: specifically reducing aging-induced adipocyte hypertrophy; decreasing the protein expression of aging markers cyclin-dependent kinase inhibitor p21(P21) and multiple tumor suppressor 1(P16); lowering the tissue inflammation reaction. Metagenomic metabolomic analysis of serum from mice in each group revealed that APS significantly increased the content of indole-3-lactic acid(ILA) in naturally aging mice. Further in vitro studies showed that ILA could improve the aging of 3T3-L1 mouse embryonic fibroblasts induced by bleomycin, reduce the protein expression of the aging marker P21, alleviate inflammation, and enhance the ability of preadipocytes to mature. Therefore, APS had the efficacy of protecting naturally aging mice, and its action may be related to the increase in the intestinal microbiota metabolite ILA. This study suggested that TCM may serve as an important entry point for explaining the mechanism of action of TCM by regulating intestinal microbiota and their functional metabolites.
