Acute lung injury (ALI) is one of the most common and critical diseases in clinical practice, with extremely high morbidity and mortality, seriously threatening human life and health. The pathogenesis of ALI is complex, in which the inflammatory response is a key factor. Studies have shown that NOD-like receptor protein 3 (NLRP3) inflammasomes are involved in ALI through mechanisms such as inflammation induction, increased microvascular permeability, recruitment of neutrophils, oxidative stress, and pyroptosis, playing a key role in the occurrence and progression of ALI. Therefore, regulating NLRP3 inflammasomes and inhibiting the release of inflammatory factors can alleviate the damage in ALI. At present, ALI is mainly treated by mechanical ventilation and oxygen therapy, which have problems such as high costs and poor prognosis. In recent years, studies have shown that traditional Chinese medicine (TCM) can reduce the inflammatory response and the occurrence of oxidative stress and pyroptosis by regulating the NLRP3 inflammasome, thus alleviating the damage and decreasing the mortality of ALI. Based on the relevant literature in recent years, this article reviews the research progress in TCM treatment of ALI by regulating NLRP3 inflammasomes, discusses how NLRP3 inflammasomes participate in ALI, and summarizes the active ingredients, extracts, and compound prescriptions of TCM that regulate NLRP3 inflammasomes, aiming to provide new ideas for the clinical treatment of ALI and the development of relevant drugs.

ObjectiveTo investigate whether there are differences in the efficacy of Gegen Qinliantang with different contents of Puerariae Lobatae Radix on the acute enteritis (AE) model mice and provide a scientific basis for the interpretation of Gegen Qinliantang in the treatment of "Xie Re Li". MethodsA total of 112 male BALB/c mice were randomly divided into a blank group,model group,single Puerariae Lobatae Radix group,non-Puerariae Lobatae Radix group,regular dose Gegen Qinliantang group (regular dose group),half-dose Puerariae Lobatae Radix group,and doubled-dose Puerariae Lobatae Radix group, with 16 mice in each group. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of the colon tissue. Western blot was employed to detect the expression of ZO-1 (a protein in the tight junction) and Occludin in the colon tissue, as well as the changes of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). ResultsCompared with the blank group,the DAI scores of the mice in the model group were significantly higher (P<0.05),and the histopathological sections of their colon tissues showed mucosal damage,glandular atrophy,disordered arrangement,and a large number of inflammatory cells infiltration,and the expression of ZO-1 and Occludin proteins in their colon tissues was significantly down-regulated (P<0.05,P<0.01). The expression of inflammatory factors TNF-α and IL-1β was significantly up-regulated (P<0.05,P<0.01). Compared with the model group,the DAI scores of mice in all dosing groups decreased significantly (P<0.05),with the most significant effect in the regular dose group. After 7 d of drug administration,the regular dose group had the best impact on the repair of colonic mucosa in the AE mouse model. The regular dose group significantly down-regulated the expression of TNF-α (P<0.05) and significantly up-regulated the expression of ZO-1 protein (P<0.05). The doubled-dose Puerariae Lobatae Radix group significantly down-regulated the expression of IL-1β protein (P<0.01),and there was no significant difference between all dosing groups and the model group in terms of the expression of Occludin protein. After 14 d of drug administration,the best effect on the repair of colonic mucosa in the AE mouse model was observed in the doubled dose Puerariae Lobatae Radix group. All groups except the non-Puerariae Lobatae Radix group significantly down-regulated the expression of TNF-α (P<0.01). Meanwhile,the regular dose group and doubled-dose Puerariae Lobatae Radix group significantly elevated the expression level of Occludin protein (P<0.01). The doubled-dose Puerariae Lobatae Radix group also significantly inhibited the expression of IL-1β protein (P<0.05) and up-regulated ZO-1 protein expression (P<0.05). ConclusionGegen Qinliantang can reduce the pathological damage of colon tissue, protect the barrier function and structure of intestinal epithelial cells, and reduce the expression of inflammatory factors, so as to achieve the therapeutic effect of AE model mice. When comparing the therapeutic efficacy of Gegen Qinliantang containing different Gegen contents, Gegen Qinliantang with the proportion of the original formula of Zhongjing was the most effective in AE model mice.

Aim To explore the effects of Lycium berry seed oil on Nrf2/ARE pathway and oxidative damage in testis of subacute aging rats. Methods Fifty out of 60 male SD rats, aged 8 weeks, were subcutaneously injected with 125 mg • kg"D-galactosidase in the neck for 8 weeks to establish a subacute senescent rat model. The presence of senescent cells was observed using P-galactosidase ((3-gal), while testicular morphology was examined using HE staining. Serum levels of testosterone (testosterone, T), follicle-stimulating hormone ( follicle stimulating hormone, FSH ) , luteinizing hormone ( luteinizing hormone, LH ) , superoxide dis-mutase ( superoxide dismutase, SOD ) , glutathione ( glutathione, GSH) and malondialdehyde ( malondial-dehyde, MDA) were measured through ELISA, and the expressions of factors related to aging, oxidative damage, and the Nrf2/ARE pathway were assessed via immunohistochemical analysis and Western blotting. Results After successfully identifying the model, the morphology of the testis was improved and the intervention of Lycium seed oil led to a down-regulation in the expression of [3-gal and -yH2AX. The serum levels of SOD, GSH, T, and FSH increased while MDA and LH decreased (P 0. 05) . Additionally, there was an up-regulated expression of Nrf2, GCLC, NQOl, and SOD2 proteins in testicular tissue ( P 0. 05 ) and nuclear expression of Nrf2 in sertoli cells. Conclusion Lycium barbarum seed oil may reduce oxidative damage in testes of subacute senescent rats by activating the Nrf2/ARE signaling pathway.

Osteoarthritis (OA) is a common degenerative joint disease with a rising incidence rate year by year. Treatment often relies on analgesics and non-steroidal anti-inflammatory drugs (NSAIDs), which can lead to gastrointestinal damage with long-term use and the recurrence of symptoms. Chinese medicine has a long history of preventing and treating OA, with widespread application and fewer side effects. It offers unique advantages such as a broad treatment scope, multiple targets, and pathways. The effective components of Chinese medicine can reduce the content of reactive oxygen species (ROS), relieve oxidative stress (OS) damage, and increase the antioxidant capacity of the body by interfering with the expression of biomarkers of OS response such as malondialdehyde (MDA) and superoxide dismutase (SOD). Through the modulation of signaling pathways such as nuclear factor E2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1), phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt), nuclear factor kappa B (NF-κB), c-Jun N-terminal kinase (JNK), NOD-like receptor protein 3 (NLRP3), and osteoprotegerin (OPG), they downregulated the expression of inflammatory factors such as interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α), thereby effectively relieving local joint inflammation, protecting chondrocytes and bone tissue, inhibiting chondrocyte apoptosis, and further alleviating the progression of OA. Currently, there are still certain limitations in the medical research status and development trends of OA, necessitating the continued advancement of traditional Chinese medicine. This paper reviewed the literature on the regulation of OS response by effective components of Chinese medicine for the prevention and treatment of OA, providing new directions and ideas for future research.
