ObjectiveTo analyze the comorbidity patterns of chronic metabolic diseases and their influencing factors among residents aged 35‒75 years old in Nantong City of Jiangsu Province, and to provide theoretical support for the prevention and control of comorbidities. MethodsThe permanent residents aged 35‒75 years from the Comprehensive Prevention and Control Project of Cardiovascular and Cerebrovascular Diseases in Nantong City from 2021 to 2024 were selected as the research subjects. Clustering analysis and association rule were used to investigate the comorbidity patterns of chronic metabolic diseases, and their influencing factors were identified through logistic regression analyses. ResultsThe prevalence of comorbidity of chronic metabolic diseases among residents aged 35‒75 years in Nantong City was 47.40%. Among comorbidity patterns based on disease counts, the prevalence of hypertension+dyslipidemia was highest in binary comorbidity patterns (6.25%), while that of hypertension+dyslipidemia+obesity was highest in ternary comorbidity patterns (4.01%). Association rules showed that in both binary and ternary comorbidity patterns, the confidence level was highest for obesity+hypertension (72.70%) and obesity+dyslipidemia+hypertension (74.54%). Renal insufficiency formed an independent cluster in cluster analyses. Logistic regression analyses revealed that, compared with the non-comorbidity group, males (OR=2.22, 95%CI: 1.69‒2.91), advanced age (45‒54 years, OR=1.38, 95%CI: 1.02‒1.88; 55‒64 years, OR=1.59, 95%CI: 1.14‒2.23; 65‒75 years, OR=2.34, 95%CI: 1.58‒3.47), and low physical activity (OR=1.26, 95%CI: 1.10‒1.65) were influencing factors for metabolic disease comorbidity. ConclusionIn the comorbidity patterns of chronic metabolic diseases among residents aged 35‒75 years in Nantong City, hypertension, diabetes mellitus, and dyslipidemia interact with each other. Individuals with obesity are more prone to diseases such as hypertension and dyslipidemia. Prevention and control of chronic metabolic diseases should be strengthened for males, individuals with low physical activity and advanced age.

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.

Hepatic stellate cells (HSCs) are the primary fibrogenic cells in the liver, and their activation plays a crucial role in the development and progression of hepatic fibrosis. Here, we report that retinoid X receptor-alpha (RXRα), a unique member of the nuclear receptor superfamily, is a key modulator of HSC activation and liver fibrosis. RXRα exerts its effects by modulating calcium/calmodulin-dependent protein kinase kinase β (CaMKKβ)-mediated activation of AMP-activated protein kinase-alpha (AMPKα). In addition, we demonstrate that K-80003, which binds RXRα by a unique mechanism, effectively suppresses HSC activation, proliferation, and migration, thereby inhibiting liver fibrosis in the CCl₄ and amylin liver NASH (AMLN) diet animal models. The effect is mediated by AMPKα activation, promoting mitophagy in HSCs. Mechanistically, K-80003 activates AMPKα by inducing RXRα to form condensates with CaMKKβ and AMPKα via a two-phase process. The formation of RXRα condensates is driven by its N-terminal intrinsic disorder region and requires phosphorylation by CaMKKβ. Our results reveal a crucial role of RXRα in liver fibrosis regulation through modulating mitochondrial activities in HSCs. Furthermore, they suggest that K-80003 and related RXRα modulators hold promise as therapeutic agents for fibrosis-related diseases.

AIM:To explore the therapeutic effect of Tongfeng-Qingli mixture(TFQLM)and its mechanism in hyperuricemic(HUA)rats based on uric acid(UA)transporter and Janus kinase 2(JAK2)/signal transducer and acti-vator of transcription 3(STAT3)signaling pathway.METHODS:(1)In vivo experiment:36 male SD rats were random-ly divided into control(CON)group,model(MOD)group,benzbromarone(BEN)group,low-dose TFQLM(TFQLM-L)group,medium-dose TFQLM(TFQLM-M)group,and high-dose TFQLM(TFQLM-H)group,with 6 rats in each group.In all groups except CON group,HUA was induced in rats by giving hypoxanthine(HP)combined with potassium oxybate(OP)for 35 consecutive days.The rats in CON group were given sodium carboxymethyl cellulose solution by gavage.A fully automatic biochemistry analyzer was used to detecte serum UA,serum creatinine(SCr)and blood urea nitrogen(BUN)levels.The xanthine oxidase(XOD)and adenosine deaminase(ADA)levels in the liver were detected by ELISA kits.The histopathological changes of kidneys were observed by HE staining.Immunohistochemistry was performed to de-tect urate transporter 1(URAT1)and glucose transporter 9(GLUT9),organic anion transporter 1(OAT1)and OAT3 ex-pression in the kidney.Western blot was used to measure the protein levels of URAT1,GLUT9,OAT1,OAT3,interleu-kin-6(IL-6),tumor necrosis factor-α(TNF-α),JAK2,p-JAK2,STAT3,p-STAT3 and repressor of cytokine signaling 3(SOCS3)in the kidney.(2)In vitro experiments:HUA cellular model was established by UA stimulation in HK2 cells,and the protein levels of URAT1,GLUT9,OAT1,OAT3,IL-6,TNF-α,JAK2,p-JAK2,STAT3,p-STAT3,and SOCS3 were detected by Western blot.RESULTS:Compared with MOD group,serum UA,SCr and BUN levels of the rats in all TFQLM groups were reduced(P<0.05).The XOD and ADA levels in liver tissues were significantly reduced(P<0.05).The protein levels of URAT1,GLUT9,IL-6,TNF-α,JAK2,p-JAK2,STAT3,p-STAT3 and SOCS3 were decreased(P<0.05),and OAT1 and OAT3 protein expression was increased(P<0.05)in kidneys and HK2 cells.CONCLUSION:By establishing rat and HK2 cell HUA models,it is hypothesized that TFQLM may reduce UA levels and attenuate renal inflammation in HUA rats,and its mechanism may be related to the regulation of UA transport proteins and inhibition of the JAK2/STAT3 signaling pathway.

【Objective】 To investigate the situation of carbapenem-resistant Enterobacteriaceae(CRE) colonization in patients undergoing haploidentical hematopoietic stem cell transplantation (haplo-HSCT). 【Methods】 A total of 241 consecutive patients who underwent haplo-HSCT in the First Affiliated Hospital of Soochow University from June 1, 2021 to June 1, 2022 were enrolled. Anal swab screening was performed within 48 hours of admission and blood cultures were taken when the patient developed fever. Univariate and multivariate analysis were used to analyze the colonization rate, distribution, risk factors and the correlation between CRE colonization and post-transplant bloodstream infection(BSI). 【Results】 Among 241 patients with haplo-HSCT, there were 90 cases in CRE colonization positive group, with a colonization rate of 37.3% (90/241). Multivariate logistic regression analysis showed that sex (OR 2.42, 95% CI 1.38-4.22, P<0.05) and history of infection within 30 days before transplantation (OR 3.37, 95% CI 1.59-7.17, P<0.05) may be independent risk factors for CRE intestinal colonization. Of the 95 CRE strains, the top five species were carbapenem-resistant Klebsiella pneumoniae (38/95, 40.0%), carbapenem-resistant Escherichia coli (29/95, 30.5%), carbapenem-resistant Enterobacter cloacae (13/95, 13.6%), carbapenem-resistant Klebsiella acidophilus (6/95, 6.3%) and carbapenem-resistant Proteus mirabilis (3/95, 3.1%). The incidence of post-transplant BSI was 12.0% (29/241) in the CRE-colonized group and 3.3% (8/241) in the non-colonized group. In the colonization group, 100% of the pathogens of BSI were identical with those of CRE colonization. 【Conclusion】 Bacterial culture of anal swab during haplo-HSCT is helpful for detection of CRE colonization in intestinal tract, which provides some clinical basis for active monitoring of key flora, prevention and control of infection.
