Lung cancer remains one of the leading causes of cancer-related morbidity and mortality worldwide, and its treatment continues to face major challenges such as therapeutic resistance and tumor recurrence. Pyroptosis, a newly characterized form of programmed cell death, induces tumor cell death through gasdermin-mediated membrane pore formation and is accompanied by the release of inflammatory mediators, thereby playing complex roles in lung cancer initiation, progression, and modulation of the tumor microenvironment. Active components and herbal formulas derived from traditional Chinese medicine can modulate pyroptosis-related signaling pathways through multi-target mechanisms, showing potential advantages in inducing lung cancer cell death, inhibiting proliferation and migration, and reversing chemoresistance. This review systematically summarizes relevant studies from domestic and international sources, focusing on the molecular mechanisms of pyroptosis, its roles in lung cancer development and tumor microenvironment remodeling, and the current research progress on traditional Chinese medicine-based interventions targeting pyroptosis, with the aim of providing references for the prevention and treatment of lung cancer using traditional Chinese medicine.

Ulcerative colitis （UC）， a chronic nonspecific inflammatory bowel disease characterized by unclear etiology， complex contributing factors， and a refractory course with malignant transformation potential， imposes a substantial burden on both individual patients and healthcare systems. There is an urgent need to explore effective therapeutic strategies and pharmacological interventions. Professor LIU Zhen， based on years of clinical practice， proposed a dynamic pathogenesis chain of UC： Spleen deficiency with dampness excess as the foundation， dampness obstruction as the nexus， stasis-toxin interaction as the key， and stasis-toxin damaging intestinal collaterals as the terminal outcome. The treatment， following the progression of deficiency （depression）-dampness-toxin-stasis （toxin）， should focus on invigorating the spleen and resolving dampness. A stage-specific treatment approach is emphasized. During the susceptible stage， prevention is recommended， which relies on regulating the diet， maintaining a positive mental state， and adjusting daily routines to invigorate the spleen and replenish Qi. During the acute attack and remission stages， the treatment should be tailored according to clinical typing and disease severity， flexibly employing therapeutic strategies such as tonifying deficiency， resolving depression， eliminating dampness， clearing heat， detoxifying， arresting bleeding， and resolving stasis in order to interrupt disease progression. In the recovery stage， latent pathogenic factors should be addressed while the postnatal constitutional foundation be preserved to prevent recurrence. According to the TCM principle of treating disease before its onset， a whole-course management path of early protection-interception-stratified care-consolidation has been developed， covering all stages of UC， to inform its clinical prevention and treatment.

OBJECTIVE To investigate the ameliorative effects of Coptidis Rhizoma-Ophiopogonis Radix herb pair （HLMD） in rats with type 2 diabetes mellitus （T2DM） and its potential mechanisms.METHODS Male Wistar rats were randomly divided into a control group （6 rats） and a model induction group （30 rats）. The T2DM rat model was established by feeding a high-sugar and high-fat diet combined with intraperitoneal injection of streptozotocin. The successfully modeled rats were subsequently divided into the model group， the metformin group （200 mg/kg）， and the low-， medium-， and high-dose HLMD groups （100， 200 and 400 mg/kg， respectively）， with six rats in each group. Rats in each group were administered the corresponding drug solution or normal saline by oral gavage once daily for six consecutive weeks. Body weight， fasting blood glucose （FBG）， the area under the curve （AUC） of the oral glucose tolerance test， serum lipid profiles [total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C）]， and inflammatory cytokine [interleukin-6 （IL-6）， IL-1β， tumor necrosis factor-α （TNF-α）， and IL-10] levels were measured. Histopathological changes in liver and pancreatic tissues， as well as hepatic lipid accumulation， were evaluated. Changes in gut microbiota composition were analyzed in the control， model， and high-dose HLMD groups. Network pharmacology and molecular docking analyses were performed to identify potential therapeutic targets of HLMD against T2DM， followed by experimental validation.RESULTS Compared with the model group， the body weight generally recovered in rats in all HLMD dose groups， while FBG levels consistently decreased. Histopathological abnormalities， including disrupted pancreatic islet architecture， disorganized hepatocyte arrangement， hepatic cord necrosis， and lipid accumulation， were alleviated to varying degrees. AUC （except for the low-dose group）， levels of TC， TG， LDL-C， IL-6（except for the low-dose group）， IL-1β and TNF-α， Simpson and Shannon indices， as well as the relative abundances of Firmicutes， Proteobacteria， and Clostridium were significantly reduced； meanwhile， the levels of HDL-C（except for the low-dose group） and IL-10 （except for the low-dose group）， as well as the relative abundances of Bacteroidota and Ligilactobacillus were significantly increased （ P ＜0.05）. Network pharmacology and molecular docking analyses suggested that the active constituents of HLMD， including quercetin， adenosine， oleanolic acid， stigmasterol， and ophiopogonin D′， may exert antidiabetic effects by targeting key proteins such as protein kinase B1（Akt1）， TNF， IL-6， P53 and IL-1β. Experimental validation further demonstrated that HLMD significantly downregulated the protein expressions of P53 （except for the low-dose group）， IL-6 （except for the low-dose group）， IL-1β and TNF-α in the liver tissues of T2DM rats （ P ＜0.05）.CONCLUSIONS HLMD alleviates glucose and lipid metabolism disorders， attenuates inflammatory responses， and ameliorates hepatic and pancreatic tissue damage in T2DM rats. These beneficial effects may be associated with the modulation of gut microbiota composition and the downregulation of inflammation-related targets， including P53， IL-6， IL-1β and TNF-α.

ObjectiveTo evaluate the inhibitory effect of online-sold “preservative-free” cosmetics against contaminated microorganisms during storage and use, to establish a method for assessing the preservative efficacy of such cosmetics, and to provide data support for the formulation of relevant standards. MethodsA total of 16 batches of cosmetics claiming preservative free were collected to determine their pH value, water activity, total aerobic microbial count (TAMC) and total molds and yeasts count (TYMC). Meanwhile, preservatives not listed in the Safety and Technical Standards for Cosmetics (2015 edition) (referred to as “unlisted preservatives”) were screened. In addition, a preservative challenge test was conducted on these cosmetics. ResultsAll the 16 batches of samples were generally weakly acidic, and with a water activity ≥0.6, which were suitable for microbial growth. Unlisted preservative not labeled on the package was detected in one batch of cosmetic. The results of neutralizer verification showed that three batches required further dilution to eliminate the antimicrobial interference. After inoculation with challenge microorganisms and cultivation for 7 days, two batches of cosmetics did not achieve a bacterial reduction rate of 99.90%, and the fungal reduction rate did not reach 90.00% either. While another two batches of cosmetics experienced microbial growth during testing, indicating a failure of the preservative challenge test. The overall pass rate was 75.00%. ConclusionSome online-sold preservative free cosmetics have insufficient preservation efficacy and pose a certain risk of microbial contamination.

Objective: To analyze the serotypes and drug resistance of Salmonella isolated from food-borne disease surveillance samples in Longwan District, Wenzhou City, Zhejiang Province, so as to provide evidence for the prevention and treatment of Salmonella infection. Methods: Salmonella strains isolated from feces or anal swabs of patients with foodborne diarrhea in Longwan District People's Hospital from 2018 to 2024 were collected. After re-identification, slide agglutination test was used to identify serotypes. The drug susceptibility test of live Salmonella strains was performed using the broth microdilution method, and the resistance patterns were analyzed. Results: A total of 2 293 samples were collected, and 186 strains of Salmonella were isolated, with a detection rate of 8.11%. The detection rate was higher from May to October. A total of 28 Salmonella serotypes were identified, with S. typhimurium (72 isolates, 38.71%), S. enteritidis (31 isolates, 16.67%), and S. London (30 isolates, 16.13%) being dominant. Among the 121 Salmonella live strains, 20 strains were susceptible to 14 antibacterial drugs. A total of 101 strains were resistant to antibacterial drugs, and the drug resistance rate was 1.65%-67.77%, with the drug resistance rate of ampicillin being the highest, and the drug resistance rate of imipenem was the lowest. S. typhimurium had the highest resistance rate to tetracycline (78.26%). S. enteritidis had the highest resistance rate to ampicillin (100.00%). S. London had the highest resistance rate to tetracycline (66.67%). Fifty-five types of drug resistance patterns were detected, showing a number of drug resistance of 1-10, of which 76 strains were multi-drug resistant, accounting for 75.25%. The predominant multidrug resistance patterns were ampicillin/sulbactam-cefazolin-ampicillin-nalidixic acid (10.53%), tetracycline-ampicillin-nalidixic acid (9.21%), and ampicillin/sulbactam-ampicillin-nalidixic acid (7.89%). Conclusions Salmonella strains isolated from foodborne diseases in Longwan District were mainly detected in summer and autumn. S. typhimurium, S. enteritidis, and S. London were the predominant serotypes. The drug resistance of Salmonella to different antibacterial drugs was different, and the drug resistance spectrum showed diversity.

Objective:To investigate the differences in resistance to chemical disinfectants between bacteriophage Phi-X174 and disinfection effect indicator microorganisms, Staphylococcus aureus and Escherichia coli. Methods:Three commonly used disinfectants, including chlorine-containing disinfectants, alcohol-based disinfectants and quaternary ammonium salt disinfectants, were selected to analyze the differences in resistance of phage Phi-X174, Staphylococcus aureus and Escherichia coli by using the quantitative sterilization test of suspension. Results:The 250 mg/L sodium dichloroisocyanurate solution treated for 10 minutes yielded log reduction values of 3.39, 7.25 and 7.37 against phage Phi-X174, Staphylococcus aureus and Escherichia coli respectively. The 40% ethanol for 1 minute yielded log reduction values of 0.03, 2.46 and 7.30 against phage Phi-X174, Staphylococcus aureus and Escherichia coli, respectively. The 100 mg/L benzalkonium chloride for 10 minutes yielded log reduction values of 1.41, 6.84 and 0.93 for phage Phi-X174, Staphylococcus aureus and Escherichia coli, respectively. Conclusion:Phage Phi-X174 has stronger resistance to chlorine-containing disinfectants and alcohol-based disinfectants than Escherichia coli and Staphylococcus aureus. Its resistance to quaternary ammonium salt disinfectants is between that of Staphylococcus aureus and Escherichia coli.

OBJECTIVES: To investigate the subcellular localization and biological functions of transmembrane protein 240 (TMEM240). METHODS: NCBI BLAST and TMHMM bioinformatics software were used for protein sequence analysis and prediction of transmembrane domain of TMEM240. Brain tissues from male C57BL/6 mice (18-20 days old) were examined for distribution of TMEM240 using in situ hybridization, and qPCR and Western blotting were used to detect TMEM240 expression in different mouse tissues and in cortical neurons at different time points (n=3). In the in vitro experiment, HepG2 and Neuro-2a cells were transfected with plasmids for overexpression of TMEM240, and subcellular localization of TMEM240 was analyzed using cell imaging. In primary cultures of cortical neurons isolated from C57BL/6 mice, TMEM240 expression and its biological functions were investigated using qPCR, Western blotting, and immunofluorescence staining. RESULTS: Human and mouse TMEM240 proteins share a 97.69% similarity in the protein sequences, and both are transmembrane proteins with two transmembrane domains. TMEM240 mRNA and protein were highly expressed in mouse brain tissues and cortical neurons. In isolated mouse cortical neurons, TMEM240 expression reached the peak level after primary culture for 9 days and distributed in scattered spots within the cells. In HepG2 cells, TMEM240 was characterized as intracellular membrane structures and showed 80% colocalization with peroxisomes. In Neuro-2a cells, TMEM240 overexpression caused significant enhancement of the expressions of Rho GDP dissociation inhibitor β (ARHGDIB) at both the mRNA and protein levels. CONCLUSIONS TMEM240 is a novel intracellular subcellular structure specifically expressed in neurons with significant potential for targeted cellular function regulation.
