Stroke is the leading cause of death and disability among adults in China， and its common complications include digestive system abnormalities， cognitive impairment， depression， stroke-associated pneumonia， and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang （XLCQT） is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically， XLCQT is often used to treat stroke and its complications. However， the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally， since the basic research is weak， the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis， medicinal properties， safety evaluation， and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients， resveratrol， kaempferol， luteolin， chrysoeriol， apigenin， （+）-catechin， and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex， including inflammatory response， brain-gut axis， hypothalamic-pituitary-adrenal （HPA） axis， intestinal flora， neurotrophic factors， autophagy， oxidative stress， and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

Diabetic kidney disease（DKD） is a chronic kidney structural and functional disorder caused by diabetes. With the global prevalence of diabetes continuing to rise， DKD has gradually become a major cause of chronic kidney disease and end-stage renal disease（ESRD）， posing a serious threat to patients' quality of life and long-term health outcomes. Studies have shown that apoptosis plays a pivotal role in the development and progression of DKD， with its mechanisms involving abnormal activation of multiple signaling pathways such as Toll-like receptor 4（TLR4）/nuclear transcription factor-κB（NF-κB）/B-cell lymphoma-2（Bcl-2）/cysteinyl aspartate-specific proteinase（Caspase）-3， protein kinase R-like endoplasmic reticulum kinase（PERK）/eukaryotic initiation factor 2α（eIF2α）/activating transcript factor 4（ATF4）/CCAAT enhancer-binding protein homologous protein（CHOP）， phosphatidylinositol 3-kinase（PI3K）/protein kinase B（Akt）/glycogen synthase kinase-3β（GSK-3β）， Janus kinase 2（JAK2）/signal transducer and activator of transcription 3（STAT3）， adenosine monophosphate-activated protein kinase（AMPK）/mammalian target of rapamycin（mTOR） and silent information regulator 1（SIRT1）/tumor suppressor protein 53（p53）， thereby accelerating renal pathological damage in DKD. Extensive evidence-based medical studies have confirmed that traditional Chinese medicine（TCM）， leveraging its unique therapeutic advantages of multi-target， multi-component and multi-pathway approaches， has demonstrated remarkable efficacy and favorable safety profiles in treating DKD. Recent studies have demonstrated that active components of TCM can specifically target and modulate key effectors in apoptotic signaling pathways. Meanwhile， traditional compound formulations exert synergistic effects through multiple approaches such as replenishing deficiency and activating blood circulation， detoxifying and dredging collaterals， tonifying kidney essence， and removing stasis and purging turbidity， thereby comprehensively regulating critical pathological processes including endoplasmic reticulum stress and mitochondrial apoptosis pathways. This combined therapeutic approach of molecular targeting and holistic regulation provides novel strategies for delaying the progression of DKD. Based on this， this paper provides an in-depth analysis of key apoptotic signaling pathways and their regulatory mechanisms， while systematically summarizing recent research advances regarding the therapeutic effects of TCM active components， compound formulations， and proprietary Chinese medicines on DKD through modulation of these pathways， with particular emphasis on their underlying molecular mechanisms. These findings not only elucidate the modern scientific connotation and theoretical basis of TCM in treating DKD but also establish a solid theoretical and practical foundation for promoting the wider clinical application and further research of TCM in the field of DKD treatment.

Lung cancer is one of the most common malignant tumors. Brain metastasis, especially meningeal metastasis, is a fatal complication of lung cancer. The sensitivity of traditional diagnostic methods for this disease is limited. As a new technology, cerebrospinal fluid liquid biopsy can noninvasively and dynamically detect the molecular characteristics of intracranial tumors. Cerebrospinal fluid directly contacts the central nervous system lesions. It contains more unique and representative tumor-derived molecular information compared with those obtained from other body fluids such as blood for lung cancer meningeal metastasis, thus remarkably improving the diagnosis and personalized treatment of lung cancer meningeal metastasis. This work reviews the research progress on cerebrospinal fluid liquid biopsy in lung cancer brain metastasis and explores its value in guiding targeted therapy, delineating drug resistance, and evaluating prognostic progression to provide new directions for the clinical diagnosis and treatment of lung cancer brain metastasis.

OBJECTIVES: To explore the mechanism of Shuangshu Decoction (SSD) for inhibiting growth of gastric cancer xenografts in nude mice. METHODS: Network pharmacology analysis was conducted to identify the common targets of SSD and gastric cancer cell ferroptosis, and bioinformatics analysis and molecular docking were used to validate the core targets. In the cell experiment, AGS cells were treated with SSD-medicated serum, Fer-1 (a ferroptosis inhibitor), or both, and the changes in cell viability, ferroptosis markers (ROS, Fe²⁺ and GSH), expressions of P53, SLC7A11 and GPX4, and mitochondrial morphology were examined. In a nude mouse model bearing gastric cancer xenografts, the effects of gavage with SSD, intraperitoneal injection of Fer-1, or their combination on tumor volume/weight, histopathology, and expressions of P53, SLC7A11 and GPX4 levels were evaluated. RESULTS: The active components in SSD (quercetin and wogonin) showed strong binding affinities to P53. In AGS cells, SSD treatment dose-dependently inhibited cell proliferation, increased ROS and Fe²⁺ levels, upregulated P53 expression, and downregulated the expressions of SLC7A11 and GPX4, but these effects were effectively attenuated by Fer-1 treatment. SSD also induced mitochondrial shrinkage and increased the membrane density, which were alleviated by Fer-1. In the tumor-bearing mouse models, gavage with SSD significantly reduced tumor size and weight, caused tumor cell necrosis, upregulated P53 and downregulated SLC7A11 and GPX4 expression in the tumor tissue, and these effects were obviously mitigated by Fer-1 treatment. CONCLUSIONS SSD inhibits gastric cancer growth in nude mice by inducing cell ferroptosis via the P53/SLC7A11/GPX4 axis.

BACKGROUND: Generalized pustular psoriasis (GPP), a rare and recurrent autoinflammatory disease, imposes a substantial burden on patients and society. Awareness of GPP in China remains limited. METHODS: This cross-sectional survey, conducted between September 2021 and May 2023 across 14 hospitals in China, included GPP patients of all ages and disease phases. Data collected encompassed demographics, clinical characteristics, economic impact, disease severity, quality of life, and treatment-related complications. Risk factors for GPP recurrence were analyzed. RESULTS: Among 127 patients (female/male ratio = 1.35:1), the mean age of disease onset was 25 years (1st quartile [Q1]-3rd quartile [Q3]: 11-44 years); 29.2% had experienced GPP for more than 10 years. Recurrence occurred in 75.6% of patients, and nearly half reported no identifiable triggers. Younger age at disease onset ( P  = 0.021) and transitioning to plaque psoriasis ( P  = 0.022) were associated with higher recurrence rates. The median diagnostic delay was 8 months (Q1-Q3: 2-41 months), and 32.3% of patients reported misdiagnoses. Comorbidities were present in 53.5% of patients, whereas 51.1% experienced systemic complications during treatment. Depression and anxiety affected 84.5% and 95.6% of patients, respectively. During GPP flares, the median Dermatology Life Quality Index score was 19.0 (Q1-Q3: 13.0-23.5). This score showed significant differences between patients with and without systemic symptoms; it demonstrated correlations with both depression and anxiety scores. Treatment costs caused financial hardship in 55.9% of patients, underscoring the burden associated with GPP. CONCLUSIONS The substantial disease and economic burdens among Chinese GPP patients warrant increased attention. Patients with early onset disease and those transitioning to plaque psoriasis require targeted interventions to mitigate the high recurrence risk.

Objective:To investigate the clinical value of puncture biopsy for the diagnosis of vessels that encapsulate tumor clusters (VETC) and macrotrabecular-massive (MTM) subtypes of hepatocellular carcinoma (HCC).Methods:One hundred and eighty-four patients with HCC who underwent surgical resection at the Fifth Medical Centre of Chinses PLA General Hospital from November 2023 to July 2024 were prospectively collected, including 154 males and 30 females, aged (57.1±8.6) years. By simulating the clinical puncture procedure, puncture biopsy tissue specimens were obtained postoperatively from the patient's isolated tumors. The puncture biopsies and surgical resection specimens were stained with HE and CD34, and evaluated for VETC and MTM. Patients were divided into two groups based on the histopathological VETC results of surgically resected specimens: the VETC-positive group ( n=41) and the VETC-negative group ( n=143); and two groups based on the histopathological MTM results of surgically resected specimens: the MTM-positive group ( n=39) and the MTM-negative group ( n=145). Clinical data such as gender, age, tumor length, and alpha-fetoprotein (AFP) were recorded. Logistic regression analysis was performed to screen the risk factors of VETC and MTM. Evaluating the diagnostic efficacy of puncture biopsy for VETC and MTM. Results:The results of multivariable logistic analysis showed that puncture biopsy VETC-positive ( OR=63.97, 95% CI: 16.28-251.29), grade of M2 microvascular invasion ( OR=5.07, 95% CI: 1.31-19.59) and tumor length ≥5 cm ( OR=3.42, 95% CI: 1.11-10.52) were the risk factors for VETC-positive (all P<0.05); whereas the risk factors for MTM-positive were only puncture biopsy MTM-positive ( OR=34.78, 95% CI: 12.06-100.29, P<0.001). Puncture biopsy correctly diagnosed VETC subtype in 163 patients with a diagnostic accuracy of 0.89, sensitivity of 0.61, specificity of 0.97, positive predictive value (PPV) of 0.83, and negative predictive value (NPV) of 0.90; MTM subtype was correctly diagnosed in 164 patients with a diagnostic accuracy of 0.89, sensitivity of 0.72, specificity of 0.94, PPV of 0.76, and NPV of 0.93. Using the three indicators of puncture biopsy diagnosis, tumor length and AFP level as a combined indicator, the accuracy to diagnose VETC was 0.83, sensitivity was 0.71, specificity was 0.87, PPV was 0.60, and NPV was 0.91; and the combined indicator diagnosis of MTM had a diagnostic accuracy of 0.85, a sensitivity of 0.82, specificity of 0.86, PPV of 0.68 and NPV of 0.95. Conclusion:Puncture biopsy has high specificity and accuracy in the diagnosis of VETC and MTM subtypes, but the sensitivity is relatively limited, and the role of puncture combined with clinical factors in improving diagnostic efficacy is limited.

Objective:To investigate the factors influencing the prescribing habits of general practitioners (GPs) in relation to single-pill combination (SPC) antihypertensive drugs.Methods:This was a qualitative study. Using the purposive sampling method, 2 general hospitals (designated as HAZ1-2) and 4 community health service centers (designated as HAS1-4) in Huai′an city, Jiangsu province were selected from April to May 2023. In addition, 4 general practitioners (designated as A-D) were selected as interviewees from each general hospital and center. The selected individuals were interviewed using on-site thematic group interviews. The interview mainly included the principles of clinical selection of SPC antihypertensive drugs; the degree of acceptance of SPC antihypertensive drugs by patients after prescription; the evaluation of SPC antihypertensive drugs and the difficulties existing in their clinical use. The data of the interview were analyzed according to the thematic framework.Results:Twenty-four GPs were interviewed. Four themes and 9 sub-themes were extracted regarding factors influencing GP prescribing of SPC antihypertensive drugs. The study showed that: (1) the prescribing of SPC antihypertensive drugs by GPs according to patients′ specific conditions; (2) the prescribing of SPC antihypertensive drugs by GPs was influenced by factors such as price and drug adjustment; (3) the different evaluations of SPC antihypertensive drugs among GPs; (4) GPs in community health service centers faced many difficulties in prescribing SPC antihypertensive drugs (relatively fewer varieties of SPC drugs in the community, lower patient trust in community GPs, and lower standardization of prescribing by community GPs).Conclusion:The factors influencing GPs′ prescribing of SPC antihypertensive drugs mainly include the patients′ specific situation, price, medication adjustment, attitude of GPs, and some clinical practice problems.

Objective:To investigate the clinical characteristics and risk factors of airway mucus plugging in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods:This was a retrospective cross-sectional study. A total of 322 hospitalized AECOPD patients admitted to the First Affiliated Hospital of Anhui Medical University from February 2023 to February 2025 were enrolled. Based on chest high-resolution computed tomography (HRCT) findings of airway mucus plugging, patients were classified into mucus plugging and non-mucus plugging groups. General and clinical data were collected, including age, sex, disease duration, smoking and alcohol history, comorbidities, number of acute exacerbations in the past year, routine blood tests, biochemical indices, pulmonary function, and pathogen detection. The incidence of airway mucus plugging in AECOPD patients was calculated, and differences in baseline characteristics, laboratory parameters, and pulmonary function between the two groups were compared. Logistic regression was used to identify independent risk factors for mucus plugging, and receiver operating characteristic (ROC) curves were plotted to evaluate the predictive value of relevant indicators.Results:Of the 322 enrolled patients, 87(27.02%) were found to have airway mucus plugging. Univariate analysis revealed statistically significant differences between the mucus plug group and the non-plug group in the following parameters (all P<0.05): body mass index (BMI), disease duration, smoking status, Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification, modified British Medical Research Council (mMRC) dyspnea scale, COPD Assessment Test (CAT) score, frequency of acute exacerbations, neutrophil percentage, absolute lymphocyte count, lymphocyte percentage, albumin, C-reactive protein (CRP), activated partial thromboplastin time, fibrinogen, fibrin(ogen) degradation products, D-dimer, Aspergillus infection rate, percentage of forced expiratory volume in 1 second to predicted value (FEV 1%pred), ratio of FEV 1 to forced vital capacity (FEV 1/FVC), and percentage of maximal mid-expiratory flow to predicted value (MMEF 75/25%pred). Multivariate logistic regression analysis identified the following as independent risk factors for airway mucus plugs (all P<0.05): elevated CRP ( OR=1.022, 95% CI: 1.013-1.036), decreased albumin ( OR=0.891, 95% CI: 0.825-0.959), Aspergillus infection ( OR=1.774, 95% CI: 1.366-2.317), and reduced MMEF 75/25%pred value ( OR=0.978, 95% CI: 0.964-0.990). ROC curve analysis showed that the combined predictive model incorporating CRP, albumin, Aspergillus infection, and MMEF 75/25%pred had an area under the ROC curve (AUC) of 0.776(95% CI: 0.714-0.838), which was superior to each individual indicator alone, with AUCs of 0.721 for CRP, 0.687 for albumin, 0.579 for Aspergillus infection, and 0.631 for MMEF 75/25%pred. Conclusions:AECOPD patients with airway mucus plugging exhibit higher inflammatory markers, poorer nutritional status, a higher likelihood of Aspergillus infection, worse pulmonary function, and poorer prognosis. Aspergillus infection, elevated CRP, decreased albumin, and reduced MMEF 75/25%pred are independent risk factors for mucus plugs in AECOPD.

Pre-admission is a critical initiative to optimize medical service processes and alleviate the challenge of "difficult access to healthcare. "However, there is currently a lack of standardized protocols for pre-admission procedures. This study aims to systematically analyze key nodes and risk factors in pre-admission process design and propose optimization strategies, providing a foundation for policy formulation and hospital practices. By constructing a "forward-reverse" dual-process model of pre-admission and identifying risk points based on stakeholder theory (patients, hospitals, healthcare administration, and insurance), the study reveals that while pre-admission can reduce the average length of stay, improve bed turnover rates, and enhance patient satisfaction, it also presents risks such as cross-period financial settlement, challenges in insurance policy adaptability, demands for information system integration, and the need for defining medical safety boundaries. To optimize the pre-admission process and mitigate these risks, this study explores framework improvements in areas including eligibility criteria, mode selection, cost settlement, transition between pre-admission and inpatient status, and cancellation of pre-admission, offering practical guidance for public hospitals. The authors argue that pre-admission requires tripartite collaboration among hospitals, insurers, and healthcare administrations: hospitals should establish top-level design, continuously refine processes, and implement dynamic risk assessment mechanisms; insurance providers should support cross-period settlement policies; and healthcare administrations should issue guiding policies or standardized protocols. Through multi-department coordination and collaborative efforts, the optimization and innovation of pre-admission processes can be advanced, ultimately delivering more efficient and convenient healthcare experiences for patients.
