ObjectiveTo observe the effects of Jiangtang No. 3 prescription on inflammatory pathways and insulin resistance-related indicators in rats with type 2 diabetes mellitus (T2DM), and to elucidate its molecular mechanism in combating diabetes. MethodsA T2DM rat model was established using a high-fat diet combined with intraperitoneal injection of streptozotocin (STZ). Successfully modeled rats were randomly assigned to the model group, metformin group, and low-, medium-, and high-dose Jiangtang No. 3 prescription groups, and a normal group was also set. Daily gavage was administered for 8 weeks as follows: metformin at 0.1 g·kg-1·d-1, Jiangtang No. 3 prescription granules at 1.62, 3.24, 6.48 g·kg-1·d-1 for the respective dose groups, and sterile water for the normal and model groups. Rat body weight, fasting blood glucose (FBG), oral glucose tolerance test (OGTT), and insulin tolerance test (ITT) were measured. After drug intervention, enzyme-linked immunosorbent assay (ELISA) was used to determine serum levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), non-esterified fatty acids (NEFA), interleukin (IL)-1β, IL-18, and insulin (INS). Hematoxylin-eosin (HE) staining was used to observe morphological changes in adipose tissue. Real-time quantitative PCR was used to detect the mRNA expression of Toll-like receptor 4 (TLR4), nuclear factor-κB (NF-κB), NOD-like receptor protein 3 (NLRP3), Caspase-1, IL-1β, IL-18, and gasdermin D (GSDMD) in adipose tissue. Western blot was used to measure the corresponding protein expression levels. ResultsCompared with the model group, Jiangtang No. 3 prescription groups exhibited significantly increased body weight (P<0.05, P<0.01), significantly reduced FBG (P<0.05, P<0.01), significant reductions in TC, TG, NEFA, and LDL (P<0.05, P<0.01), and a significant increase in HDL (P<0.01). Serum levels of inflammatory mediators IL-1β and IL-18 were significantly decreased (P<0.01), the homeostatic model assessment of insulin resistance (HOMA-IR) index was significantly reduced (P<0.05, P<0.01), and adipose tissue pathology was improved. The protein expression levels of TLR4, NF-κB, NLRP3, Caspase-1, IL-1β, IL-18, and GSDMD were markedly decreased (P<0.05, P<0.01), and the mRNA expression levels of these indicators were also significantly downregulated (P<0.05, P<0.01). Some effects were superior to those of the positive control drug metformin, and certain indicators exhibited dose-dependent improvements. ConclusionT2DM rats display significant inflammatory responses, disordered glucose and lipid metabolism, and insulin resistance. Jiangtang No. 3 prescription effectively suppresses inflammatory mediators, improves glucose and lipid metabolism and insulin resistance, and ameliorates pathological changes in adipose tissue. Its mechanism may be related to the regulation of the TLR4/NF-κB/NLRP3 signaling pathway in visceral adipose tissue, thereby influencing downstream inflammatory mediators.

To explore the correlation between MTHFR C677T gene polymorphism and hypertension, hyperhomocysteinemia(Hcy), and hyperlipidemia in the Tibetan population of Tibet. Using a cluster sampling method, participants from high-altitude regions including Ngari Prefecture, Lhasa City, and Nyingchi City in Tibet were enrolled. Differences in MTHFR C677T genotype distribution among individuals with hypertension, HHcy, and hyperlipidemia were analyzed, and multivariate logistic regression was performed to assess the association between these conditions and the TT genotype. A total of 574 eligible subjects were included, with a mean age of 40.64±12.67 years. Males accounted for 46.7%(268/574) and females 53.3%(306/574). Regional distribution was 34.8%(200/574) from Nyingchi City, 33.1%(190/574) from Lhasa City, and 32.1%(184/574) from Ngari Prefecture. Mean systolic and diastolic blood pressures were 117.89±18.98 mm Hg and 79.74±14.88 mm Hg, respectively. The frequency of the TT genotype was significantly higher in the hypertension group than in the non-hypertension group(12.32% The MTHFR C677T TT genotype is significantly associated with hypertension and hyperhomocysteinemia in the Tibetan population, suggesting that this polymorphism may be a genetic risk factor for these diseases in high-altitude regions.

ObjectiveTo investigate the effects of retention enema with Huangling Jiedu Xiezhuo granules(HJXG) on Nod-like receptor protein 3(NLRP3), intestinal flora, and short-term prognosis in patients with gout. MethodsA total of 60 patients with gout admitted to the hospital from January 2021 to December 2023 were selected and divided into a control group and an observation group according to the random number table method, with 30 cases in each group. The control group was treated with febuxostat, and the observation group was treated with retention enema with HJXG on the basis of the control group. After 14 days of continuous treatment, the clinical efficacy, traditional Chinese medicine (TCM) syndrome score, and visual analogue scale (VAS) pain index of the two groups were compared, and serum creatinine(SCr), blood urea nitrogen(BUN), uric acid(UA), cystatin C(CysC), β2- microglobulin(β2-MG), glomerular filtration rate test(GFR), creatinine clearance rate (Ccr), erythrocyte sedimentation rate(ESR), hypersensitive C-reactive protein,(hs-CRP), interleukin 6(IL-6), interleukin-1β(IL-1β), interleukin-18 (IL-18), NLRP3 inflammasome levels, and the number of intestinal flora were detected in the two groups. The prognosis of patients was followed up within 12 weeks. COX regression analysis was used to analyze the effect of short-term prognosis. ResultsAfter treatment, TCM syndrome scores and VAS pain index in both groups were reduced (P<0.05), and TCM syndrome scores in the observation group were significantly lower than those in the control group. After treatment, ESR, hs-CRP, IL-6, NLRP3, IL-18, and IL-1β were significantly decreased in both groups (P<0.01), and the levels of IL-6, ESR, NLRP3, and IL-18 were significantly improved in the observation group compared with the control group (P<0.05). BUN, SCr, UA, β2-MG, GFR indexes in both groups were significantly lower after treatment, Ccr indexes in both groups were significantly higher after treatment, and the levels of SCr, UA, CysC, and Ccr in the observation group were significantly better than those in the control group (P<0.05). After treatment, the intestinal flora in both groups was improved, and the observation group was significantly improved compared with the control group in terms of Lactobacillus, Proteus, Bacteroides, and Escherichia coli (P<0.05). COX regression analysis showed that retention enema with HJXG could reduce the risk of poor short-term prognosis in patients with gout compared with Western medicine alone. ConclusionThe retention enema with HJXG can improve the curative effect of patients with gout, improve the TCM syndromes, reduce inflammation, and enhance renal function, intestinal flora, and short-term prognosis.

OBJECTIVE To investigate the effect and mechanism of Jingangteng capsules in the treatment of non-alcoholic fatty liver disease (NAFLD). METHODS Thirty-two SD rats were randomly divided into normal group and modeling group. The modeling group was fed a high-fat diet to establish a NAFLD model. The successfully modeled rats were then randomly divided into model group, atorvastatin group[positive control, 2 mg/(kg·d)], and Jingangteng capsules low- and high-dose groups [0.63 and 2.52 mg/(kg·d)], with 6 rats in each group. The pathological changes of the liver were observed by hematoxylin-eosin staining and oil red O staining. Enzyme-linked immunosorbent assay was performed to determine the serum levels of triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), alanine transaminase (ALT), aspartate transaminase (AST), tumour necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6, IL-18. 16S rDNA amplicon sequencing and metabolomics techniques were applied to explore the effects of Jingangteng capsules on gut microbiota and metabolisms in NAFLD rats. Based on the E-mail:591146765@qq.com metabolomics results, Western blot analysis was performed to detect proteins related to the nuclear factor kappa-B (NF-κB)/NOD-like receptor family protein 3 (NLRP3) signaling pathway in the livers of NAFLD rats. RESULTS The experimental results showed that Jingangteng capsules could significantly reduce the serum levels of TG, TC, LDL-C, AST, ALT, TNF-α, IL-1β, IL-6, IL-18, while increased the level of HDL-C, and alleviated the hepatic cellular steatosis and inflammatory infiltration in NAFLD rats. They could regulate the gut microbiota disorders in NAFLD rats, significantly increased the relative abundance of Romboutsia and Oscillospira, and significantly decreased the relative abundance of Blautia (P<0.05). They also regulated metabolic disorders primarily by affecting secondary bile acid biosynthesis, fatty acid degradation, O-antigen nucleotide sugar biosynthesis, etc. Results of Western blot assay showed that they significantly reduced the phosphorylation levels of NF-κB p65 and NF-κB inhibitor α, and the protein expression levels of NLRP3, caspase-1 and ASC (P<0.05 or P<0.01). CONCLUSIONS Jingangteng capsules could improve inflammation, lipid accumulation and liver injury in NAFLD rats, regulate the disorders of gut microbiota and metabolisms, and inhibit NF-κB/NLRP3 signaling pathway. Their therapeutic effects against NAFLD are mediated through the inhibition of the NF-κB/NLRP3 signaling pathway.

Objective:To investigate and analyze the current status of dietary behavior compliance among patients following bariatric metabolic surgery, as well as its associated influencing factors.Methods:A convenience sampling approach was employed to select 149 discharged patients who underwent bariatric metabolic surgery at the Gastric Surgery Department of a tertiary hospital in Fuzhou between August 2021 and February 2024. A WeChat communication group was established for survey participants, and a questionnaire survey was conducted via the mobile app "Wenjuanxing." Patients′ data were collected using the General Information Questionnaire and the Dietary Behavior Compliance Scale for Patients After Bariatric Metabolic Surgery. Multiple stepwise linear regression analysis was used to evaluate the influencing factors of dietary behavior compliance in postoperative patients.Results:A total of 165 questionnaires were distributed, with 149 valid responses retrieved. Among the 149 post-bariatric surgery patients, 37 were males and 112 were females, with an average age of (31.10 ± 7.26) years. The overall level of dietary behavior compliance was (56.91 ± 9.70). Significant differences in dietary behavior compliance were observed among patients of different genders, educational levels, drinking habits, and postoperative durations ( t = 2.17, 1.93, F = 4.27, 3.50, all P<0.05). Specifically, postoperative duration emerged as the primary factor influencing dietary behavior compliance following bariatric metabolic surgery ( t = -2.22, P<0.05). Conclusions:Female patients, those with a college degree or higher, and individuals within 0 to 6 months post-surgery demonstrated better dietary behavior compliance. Medical staff should comprehensively consider patient individual differences, develop, and implement personalized health education plans to enhance patient dietary behavior compliance.

Journal of Sun Yat-sen University(Medical Sciences) 2025;46(3):361-370
Breast cancer is one of the most common cancers in women, which seriously threatens women's health. Early diagnosis and precise treatment of breast cancer are helpful to improve the prognosis of patients. This article summarizes the research status of bacteria and their metabolites in the development and treatment of breast cancer, and discusses in detail the role and mechanism of bacteria and their metabolites in the development and intervention of breast cancer. These mechanisms include regulation of inflammation and immune response, DNA damage, and regulation of cell biological characteristics. Engineering bacteria have become one of the hotspots in the field of breast cancer treatment in recent years due to their natural advantages in targeting tumors and activating immunity. This article further summarizes the research progress of engineered bacteria in the treatment of breast cancer, aiming to provide an important reference for formulating targeted treatment strategies and improving the prognosis of patients. Although bacteria and their metabolites affect the development and treatment of breast cancer through a variety of mechanisms, and can enhance the therapeutic effect of cancer and reduce the adverse effects of treatment, the clinical application of bacteria in anti-breast cancer therapy still faces numerous challenges. The highly individualized composition of bacteria leads to the lack of universality of treatment, and the complex interaction between bacteria and host further increases the difficulty of research. In the future, it is urgent to further explore the mechanism of bacteria and their metabolites affecting the development and treatment of breast cancer, and promote the clinical application of bacteria in anti-breast cancer treatment.

Objective To systematically evaluate the risk factors for persistent cough after lung resection, providing a theoretical basis for preventing persistent postoperative cough. Methods The Cochrane Library, Web of Science, EMbase, PubMed, Chinese Biomedical Literature Database, Wanfang, CNKI, and VIP databases were searched for studies related to risk factors for persistent cough after lung resection. The search period was from database inception to March 30, 2023. Two researchers independently screened the literature, extracted data, and performed quality assessment. RevMan 5.3 software was used for meta-analysis. Results A total of 17 articles with 3 698 patients were included. Meta-analysis results showed that females [OR=3.10, 95%CI (1.99, 4.81), P<0.001], age [OR=1.72, 95%CI (1.33, 2.21), P<0.001], right-sided lung surgery [OR=2.36, 95%CI (1.80, 3.10), P<0.001], lobectomy [OR=3.40, 95%CI (2.47, 4.68), P<0.001], upper lobectomy [OR=8.19, 95%CI (3.87, 17.36), P<0.001], lymph node dissection [OR=3.59, 95%CI (2.72, 4.72), P<0.001], bronchial stump closure method [OR=5.19, 95%CI (1.79, 16.07), P=0.002], and postoperative gastric acid reflux [OR=6.24, 95%CI (3.27, 11.91), P<0.001] were risk factors for persistent cough after lung resection, while smoking history was a protective factor against postoperative cough [OR=0.59, 95%CI (0.45, 0.77), P<0.001]. In addition, the quality of life score of patients with postoperative cough decreased compared with that before surgery [MD=1.50, 95%CI (0.14, 2.86), P=0.03]. Conclusion Current evidence suggests that females, age, right-sided lung surgery, lobectomy, upper lobectomy, lymph node dissection, bronchial stump closure method (stapler closure), and postoperative gastric acid reflux are independent risk factors for persistent postoperative cough in lung resection patients, while smoking history may be a protective factor against postoperative cough. This provides evidence-based information for clinical medical staff on how to prevent and reduce persistent postoperative cough in patients and improve their quality of life in the future.
