ObjectiveTo explore the clinical efficacy and mechanism of Bupi Qingfei prescription (BPQF) in treating stable bronchiectasis in the patients with syndromes of lung-spleen Qi deficiency and phlegm-heat accumulation in the lungs. MethodsA randomized, double-blind, placebo-controlled trial was conducted. Patients were randomized into BPQF and placebo control (PC) groups. On the basis of conventional Western medicine treatment, the BPQF granules and placebo were respectively administered at 10 g each time, twice a day, for a course of 24 weeks. The TCM symptom scores, Quality of Life Questionnaire for Bronchiectasis (QOL-B) scores, lung function indicators, T lymphocyte subsets, level of inflammatory factors in the sputum, level of neutrophil elastase (NE) in the sputum, and occurrence of adverse reactions were observed before and after treatment in the two groups. ResultsA total of 64 patients completed the study, encompassing 32 in the BPQF group and 32 in the PC group. After treatment, the BPQF group showed decreased TCM symptom scores (P<0.01), increased QOL-B scores (P<0.01), and declined levels of tumor necrosis factor (TNF)-α and NE (P<0.05, P<0.01). The PC group showed decreased TCM symptom (except spleen deficiency) scores (P<0.01), increased the QOL-B health cognition and respiratory symptom domain scores (P<0.05, P<0.01), and a declined TNF-α level (P<0.01). Moreover, the BPQF group had lower TCM symptom (except chest tightness) scores (P<0.05, P<0.01), higher QOL-B (except treatment burden) scores (P<0.05, P<0.01), and lower levels of interleukin-6 and TNF-α (P<0.05) than the PC group. Neither group showed serious adverse reactions during the treatment process. ConclusionBPQF can ameliorate the clinical symptoms of stable bronchiectasis patients who have lung-spleen Qi deficiency or phlegm-heat accumulation in the lungs by regulating the immune balance and inhibiting airway inflammatory responses.

ObjectiveAge-related macular degeneration (AMD) is one of the leading causes of low vision and blindness in people over 50 years old, and dry AMD (dAMD) is one type for which there is currently no clear treatment. On the basis of the diagnosis and clinical characteristics of dAMD in traditional Chinese and Western medicine, this paper evaluated the fitting degrees of existing animal models of dAMD with clinical characteristics according to the evaluation methods of animal models, and put forward suggestions and prospects. MethodsLiterature on animal models of dAMD was searched against database, and the characteristics of the models were assigned according to the diagnosis criteria of diseases and syndromes of traditional Chinese and Western medicine, and the fitting degrees of the models with clinical characteristics were analyzed and evaluated. ResultsAt present, the animal models of dAMD are mainly established targeting complement factors, chemokines, oxidative damage, lipid/glucose metabolism, and natural strains. Most of the models can simulate the major pathological changes of dAMD, showing the fitting degree of 25%-50% with clinical characteristics in Western medicine. However, the evaluation of traditional Chinese medicine (TCM) syndromes, especially the evaluation of secondary syndromes, is missing, and the models present low fitting degrees with the clinical characteristics in TCM. ConclusionExisting animal models of dAMD are mostly established under the guidance of Western diagnostic standards, which reproduce the main disease characteristics of Western medicine and lack observation of TCM syndromes. Future studies can pay attention to the intervention factors and evaluation systems of spleen deficiency Qi deficiency and liver-kidney Yin deficiency syndrome and build the animal model of dAMD with integration of disease and syndrome based on clinical characteristics of traditional Chinese and Western medicine.

ObjectiveRetinal vein occlusion (RVO) is the second most common vascular disease leading to vision loss. Since its pathogenesis remains unclear, current Western medical treatments primarily target complications such as macular edema and neovascularization. The main therapeutic approaches include intravitreal injections of anti-vascular endothelial growth factor (VEGF) agents or corticosteroids, laser photocoagulation, and pars plana vitrectomy. However, these treatments cannot fully reverse disease progression or structural damage. Traditional Chinese medicine (TCM) has unique advantages in the clinical diagnosis and treatment of RVO, and integrated Chinese and Western medicine approaches may offer better clinical outcomes. This study, based on the clinical manifestations of RVO, systematically reviews the existing literature and evaluates the alignment of current RVO animal models with clinical manifestations. The aim is to identify the characteristics and limitations of existing models and provide recommendations and prospects for developing RVO animal models featuring the combination of disease and syndrome. MethodsDatabases including CNKI, Wanfang Data, PubMed, and Web of Science were searched with the keywords of "retinal vein occlusion" and "animal model". Model characteristics were assessed based on the diagnostic criteria for diseases and syndromes in both TCM and Western medicine. The alignment of each model with clinical manifestations was analyzed and evaluated. ResultsThe available RVO models were primarily established via methods such as laser photocoagulation, photodynamic therapy, diathermy, intravitreal drug injection, and mechanical modeling. These models demonstrated moderate overall alignment with clinical manifestations, mainly reflecting disease characteristics. However, they generally lack representation of TCM syndrome features. ConclusionExisting RVO models are predominantly based on Western medicine and lack TCM syndrome features. Western medical treatments for RVO have certain limitations, while syndrome differentiation and treatment in TCM offer potential advantages. Future research should focus on developing disease-syndrome integrated animal models that incorporate both pathological features and TCM syndrome characteristics. This approach will enhance the design of RVO models and facilitate both basic and clinical research, which make it a scientifically valuable and necessary endeavor.

Pancreatic cancer is a highly malignant solid tumor of the digestive system with extremely poor treatment prognosis. Although its incidence rate is low, its mortality rate is extremely high. In recent years, the number of diagnosed cases worldwide has continued to rise, making pancreatic cancer the sixth leading cause of cancer-related deaths globally. Currently, clinical treatment primarily relies on operation and chemotherapy to suppress tumors. However, these approaches face challenges such as suboptimal efficacy, high postoperative recurrence rates, and severe adverse reactions. Therefore, identifying safe and effective treatment modalities remains a pressing challenge for the medical community. In recent years, research on traditional Chinese medicine (TCM) interventions for pancreatic cancer has increased significantly. Multiple studies have shown that single-herb TCM, TCM formulas, and their derived single compounds can regulate the levels of tumor cell signaling pathways through multiple action targets. They inhibit the development and progression of pancreatic cancer by inhibiting cancer cell proliferation, promoting cell apoptosis, inhibiting tumor angiogenesis, reducing cancer cell invasion and migration capabilities, regulating the cell cycle, and modulating the tumor microenvironment. Additionally, TCM has the advantages of significantly enhancing the anticancer efficacy of chemotherapy drugs and causing fewer adverse reactions. However, the specific action mechanisms by which TCM intervenes in pancreatic cancer remain unclear. Further extensive research is still needed to validate the role of regulating classical signaling pathways such as phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR), Wnt/β-catenin, nuclear transcription factor-κB (NF-κB), notch, and hedgehog in the treatment of pancreatic cancer. Therefore, this paper reviewed Chinese and international studies on TCM intervention in pancreatic cancer through relevant signaling pathways in recent years, summarized the potential action mechanisms of TCM in the treatment of pancreatic cancer, and provided references for related research in the future.

OBJECTIVE To investigate the influence of CYP2C19 gene polymorphism on platelet function and inflammatory cytokines in elderly patients with ischemic stroke, and to analyze potential factors associated with poor prognosis. METHODS A retrospective study was conducted on elderly patients with ischemic stroke admitted to our hospital from June 2024 to June 2025, wh o underwent CYP2C19 genotype testing and received antiplatelet therapy with clopidogrel. The levels of platelet function indicators and inflammatory cytokines before and after treatment were compared among patients with different metabolic phenotypes. Based on the prognosis at 6 months post-treatment, patients were divided into poor prognosis group and good prognosis group. Univariate analysis was performed on general data, metabolic phenotype, the levels of platelet function indicators and inflammatory cytokines. Variables with P <0.05 and the levels of inflammatory cytokines before treatment were included in a multivariate Logistic regression analysis to identify independent risk factors for poor prognosis. Multiple linear regression was used to further analyze the relationship between metabolic phenotypes and inflammatory cytokines. RESULTS A total of 448 elderly patients with ischemic stroke were included; among them, 162 cases were normal metabolic phenotype, 218 were intermediate metabolic phenotype, and 68 were poor metabolic phenotype. No rapid or ultrarapid metabolic phenotypes were observed. After treatment, platelet aggregation rate, the levels of P-selectin and platelet activated complex-1 (PAC-1), high-sensitivity C-reactive Protein (hs-CRP), interleukin-1β (IL-1β), IL-6 and tumor necrosis factor-α (TNF-α) in the normal metabolic phenotype group, intermediate metabolic phenotype group, and poor metabolic phenotype group (except for platelet aggregation rate, and the levels of P-selectin and PAC-1 in the poor metabolic phenotype group) were significantly lower than those before treatment in the same group. Moreover, the above indicators in the normal metabolic phenotype group were significantly lower than those in the intermediate and poor metabolic phenotype groups at the corresponding time, and the levels of platelet function indicators in the intermediate metabolic phenotype group were significantly lower than those in the poor metabol ic phenotype group at the corresponding time ( P <0.05). Univariate and multivariate Logistic regression analyses showed that combined with hypertension, combined with diabetes mellitus, and intermediate or poor metabolic genotypes were independent risk factors for poor prognosis in elderly patients with ischemic stroke ( P <0.05). Multiple linear regression analysis showed that serum levels of hs-CRP, IL-1β, IL-6 and TNF-α before treatment were significantly higher in patients with intermediate and poor metabolic genotypes compared to those with normal metabolic genotype ( P <0.05), with a greater magnitude of increase in inflammatory cytokines observed in the patients with poor metabolic genotype. CONCLUSIONS The elderly ischemic stroke patients with CYP2C19 intermediate and poor metabolic genotypes have poor inhibition effect on platelet and higher levels of inflammatory cytokines than normal metabolic genotype; CYP2C19 gene polymorphism, and in combination with hypertension and diabetes, can be used as independent predictors of poor prognosis.

Objective To comprehensively investigate the levels of exposure and distribution characteristics of trihalomethanes (THMs) in drinking water in Guangzhou City, and evaluate the health risks of different groups of children, adolescents and adults, and to provide data and evidence for protecting human health and promoting risk control of drinking water. Methods According to the technical requirements of the "Standards for Drinking Water Quality Testing Methods" (GB/T 5750-2023), the concentration of THMs, including trichloromethane (TCM), bromodichloromethane (BDCM), dibromochloromethane (DBCM), and tribromomethane (TBM) in drinking water in Guangzhou City from 2023-2024 were detected. The health risk model recommended by USEPA was used for risk assessment.Results TCM, BDCM and DBCM were detected in the factory water and terminal water, with TCM contributing the most. There was a statistically significant difference (P<0.05) between the wet and dry seasons, and the concentration of TCM in the wet season was higher than that in the dry season. Among the multiple exposure factors, the amount of exposure through drinking water intake was much greater than that through skin absorption. The carcinogenic risk index of THMs for children, adolescents, and adults was 22.0×10-6, 12.2×10-6, and 11.4×10-6, respectively, while the non-carcinogenic risk was less than 1. Conclusion The exposure risks of THMs in children, adolescents, and adults is within an acceptable range, but monitoring needs to be strengthened, with a particular focus on children.

Autoimmune hepatitis (AIH) is a chronic, immune-mediated liver injury of unknown etiology. The onset of this disease involves the activation and recruitment of diverse immune and non-immune cells, which in turn trigger hepatic damage. Immune checkpoint molecules (ICM) are expressed on the surface of multiple cell types. By regulating cellular functional states, they help limit the intensity and duration of immune responses, thereby preventing excessive inflammation and tissue damage, and maintaining immune homeostasis. In AIH, however, this natural "braking" mechanism is impaired, leading to aberrant activation of both immune and non-immune cells and the breakdown of immune homeostasis. Consequently, ICM are likely to play a critical role in the pathogenesis of AIH. A deeper understanding of the function of ICM in AIH not onlyadvances our insight into the disease mechanism, but also suggests that targeting these molecules may represent a promising therapeutic strategy for the treatment of AIH.
