ObjectiveTo investigate the therapeutic effect and mechanism of Solanum nigrum on hepatic fibrosis induced by carbon tetrachloride (CCl4) in rats. MethodsSixty SD rats were randomly allocated into blank, model, low-, medium-, and high-dose (0.9, 1.8, 3.6 g·kg-1, respectively) S. nigrum, and silibinin capsules (18.9 mg·kg-1) groups. Except the blank group, the other groups were subjected to intraperitoneal injection of 40% CCl4 solution for the modeling of hepatic fibrosis. After 4 weeks of gavage, blood was collected from the abdominal aorta following intraperitoneal anesthesia. The rats were sacrificed, and the liver was separated. The pathological changes were observed by hematoxylin-eosin staining and Masson staining. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and liver fibrosis indexes [type Ⅲ procollagen (PCⅢ), type Ⅳ collagen (Col Ⅳ), laminin (LN), and hyaluronic acid (HA)] in the rat serum were determined. The mRNA and protein levels of B cell lymphoma-2 (Bcl-2)/Bcl-2-associated X protein (Bax)/cysteinyl aspartate-specific proteinase-3 (Caspase-3) pathway-related factors were determined by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot, respectively. ResultsCompared with the blank group, the model group exhibited significant hepatocyte edema, infiltration of inflammatory cells, connective tissue proliferation, and collagen fiber deposition in the liver tissue. Compared with the model group, low-, medium-, and high-dose S. nigrum and silymarin capsules significantly improved the structure of liver cells and alleviated the edema, inflammatory cell infiltration, connective tissue proliferation, and collagen fiber deposition. Compared with those in the blank group, the serum levels of ALT, AST, PCⅢ, Col Ⅳ, LN, and HA were elevated in the model group (P<0.01). Compared with the model group, the serum levels of ALT, AST, PCⅢ, Col Ⅳ, LN, and HA were reduced in all the treatment groups (P<0.05). Real-time PCR and Western blot results showed that compared with the blank group, the model group had up-regulated mRNA and protein levels of Bcl-2 and down-regulated mRNA and protein levels of Bax and Caspase-3 (P<0.01). Compared with the model group, all the treatment groups showed down-regulated mRNA and protein levels of Bcl-2 and up-regulated mRNA and protein levels of Bax and Caspase-3 (P<0.05), with the high-dose S. nigrum group showing the best therapeutic effect. ConclusionS. nigrum modulates the progression of hepatic fibrosis in rats by regulating apoptosis through the Bcl-2/Bax/caspase-3 pathway.

ObjectiveTo assess the efficacy and safety of the Qi-regulating and phlegm-removing method(Liu Junzitang Combined with Linggang Wuwei Jiangxintang) for treating acute exacerbations of chronic obstructive pulmonary disease (AECOPD) with increased eosinophils (EOS). MethodsSixty-eight AECOPD patients with increased EOS who were hospitalized in the Department of Pulmonary Diseases of Jinhua Traditional Chinese Medicine Hospital from April 2023 to April 2024 were recruited and randomly assigned to an experimental group (EG) or a control group (CG). Both groups received conventional Western medicine, with the EG additionally receiving Liujunzitang and Linggan Wuwei Jiangxintang. The therapeutic efficacy indicators were measured after the treatment. The main therapeutic efficacy indicators included partial pressure of oxygen (PaO2) and partial pressure of carbon dioxide (PaCO2). The secondary efficacy indicators included the TCM symptom scores, the COPD Assessment Test (CAT) score, the Modified Medical Research Council (mMRC) Dyspnea Scale score, and the length of hospital stay. The indicators were measured at baseline and on days 3 and 7 of intervention. The safety was evaluated based on the adverse events. ResultsBaseline characteristics were not statistically different between the two groups. Compared with CG, EG showed no significant difference in PaO2 (P=0.773), PaCO2 (P=0.632) and or CAT score (P=0.336) at on day 3 but better PaO2 (P=0.004), PaCO2 (P=0.008), and CAT score (P=0.013) were significantly better at on day 7. Compared with CGAfter treatment, EG had lower TCM syndrome scores of than CG EG on day 3 (P=0.005) and day 7 were significantly decreased (P0.001). There was no significant difference in mMRC score between the two groups on day 3 (P=0.514) and day 7 (P=0.176) as wasor the length of hospital stay (P=0.915). The generalized linear mixed model (GLMM) showed that compared with CG, EG had significant improvements over time in PaO2, PaCO2, TCM syndrome symptom scores, CAT score, and mMRC score.

ObjectivePolygoni Multiflori Radix is a commonly used tonic traditional Chinese medicine (TCM) in clinical practice, but liver injury has often been reported in recent years. Some related preparations containing Polygoni Multiflori Radix have been reported by the National Medical Products Administration many times for the risk of liver injury. This has caused extensive discussion on the potential toxicity of TCM in China and abroad, which has limited the clinical use of Polygoni Multiflori Radix to some extent. To understand the adverse reactions of Polygoni Multiflori Radix, the safe and rational use of Polygoni Multiflori Radix in clinical practice was discussed. MethodsThe pharmacovigilance thought of modern Chinese medicine and the TCM pharmacovigilance system framework of ''identification of poison, use of poison, anti-poison, and detoxification'' were employed to mine the relevant toxicity records, usage and dosage, processing compatibility, and contraindication of taking Polygoni Multiflori Radix in ancient books. The drug safety information of Polygoni Multiflori Radix was summarized by comparing with modern reports. ResultsA total of 74 ancient books related to Polygoni Multiflori Radix were included, suggesting that the toxicity of Polygoni Multiflori Radix was recognized in ancient times. The main chemical components of Polygoni Multiflori Radix had both efficacy and toxicity, and the adverse reactions may be related to long-term use, excessive use, and individual differences. The results showed that the toxic components of Polygoni Multiflori Radix could be reduced by peeling, steaming with black beans, and processing without iron tools. The toxic effects of Polygoni Multiflori Radix could be reduced by the compatibility of Polygoni Multiflori Radix with Poria, Psoraleae Fructus, and Cistanches Herba. ConclusionReasonable dosage, standard processing, correct compatibility, and syndrome differentiation are the key points to standardize the use of Polygoni Multiflori Radix and reduce the incidence of adverse reactions. Clinically, the toxicity classification of TCM should be strengthened, and the susceptible population should be prioritized. The detection indicators and early warning mechanisms should be improved, and precise drug dosage and course of treatment should be guaranteed. These measures can ensure the safe use of Polygoni Multiflori Radix.

Risk prediction models for postoperative pulmonary complications (PPCs) can assist healthcare professionals in assessing the likelihood of PPCs occurring after surgery, thereby supporting rapid decision-making. This study evaluated the merits, limitations, and challenges of these models, focusing on model types, construction methods, performance, and clinical applications. The findings indicate that current risk prediction models for PPCs following lung cancer surgery demonstrate a certain level of predictive effectiveness. However, there are notable deficiencies in study design, clinical implementation, and reporting transparency. Future research should prioritize large-scale, prospective, multi-center studies that utilize multiomics approaches to ensure robust data for accurate predictions, ultimately facilitating clinical translation, adoption, and promotion.

OBJECTIVE To investigate the ameliorative effects and mechanisms of Miao medicine Euphorbia humifusa on hepatic fibrosis (HF) model rats. METHODS Thirty-eight rats were randomly assigned according to a random number table into control group (normal saline, n=7), model group (normal saline, n=7), E. humifusa low-, medium- and high-dose groups (0.675, 1.35, 2.70 g/kg, n=6), and silybin group (positive control, 18.9 mg/kg, n=6). All groups except the control group were subjected to HF induction via intraperitoneal injection of carbon tetrachloride. After modeling, rats were administered their respective drugs/normal saline by gavage, once a day, for 30 days. At the last medication, the liver index was calculated, and serum levels of tumor necrosis factor-α (TNF-α), interleukin-17 (IL-17), IL-1β, IL-6, alanine transaminase (ALT), aspartate transaminase (AST), and hydroxyproline (HYP) were measured. Liver morphology and HF changes were observed. Levels of transforming growth factor- β1 (TGF- β1) and α-smooth muscle actin (α-SMA), as well as the expressions of α -SMA, proteins related to TNF- α/NF- κB signaling pathway, mRNA expressions of TNF-α and NF-κB p65 in liver tissue were determined. RESULTS Compared with model group, liver index, serum levels of TNF-α, IL-17, IL-1β, IL-6, ALT, AST and HYP, relative expression of NF-κB p65 mRNA, and the levels of TNF-α and α-SMA proteins and phosphorylated NF-κB p65 in liver tissues of rats from administration groups, the expressions of α-SMA and TGF-β1 in liver tissue of rats from E. humifusa medium-dose and high-dose groups, as well as positive staining percentage and mRNA expression of TNF- α in liver tissue of rats from E. humifusa high-dose group were all decreased significantly (P<0.05 or P<0.01); IκBα protein expression from administration groups was significantly increased (P<0.05 or P<0.01). Pathological changes and the degree of HF in the liver tissues of rats from administration groups were ameliorated to various extents. CONCLUSIONS E. humifusa may alleviate HF in rats by inhibiting the activation of the TNF-α/NF-κB signaling pathway.

Objective:
To investigate the urban and rural differences in adverse outcomes of pulmonary tuberculosis (PTB) in patients with pulmonary tuberculosis-diabetes mellitus comorbidity (PTB-DM), so as to provide insights into improving the prevention and treatment measures for PTB-DM.
Methods:
Patients with PTB-DM who were admitted and discharged from 14 designated tuberculosis hospitals in Hangzhou City from 2018 to 2022 were selected. Basic information, and history of diagnosis and treatment were collected through hospital information systems. The adverse outcomes of PTB were defined as endpoints, and the proportions of adverse outcomes of PTB in urban and rural patients with PTB-DM were analyzed. Factors affecting the adverse outcomes of PTB were identified using a multivariable Cox proportional hazards regression model.
Results:
A total of 823 patients with PTB-DM were enrolled, including 354 (43.01%) urban and 469 (56.99%) rural patients. There were 112 (13.61%) patients with adverse outcomes of PTB. The proportions of adverse outcomes of PTB in urban and rural patients were 14.41% and 13.01%, respectively, with no statistically significant difference (P>0.05). Multivariable Cox proportional hazards regression analysis identified first diagnosed in county-level hospitals or above (HR=2.107, 95%CI: 1.181-3.758) and drug resistance (HR=3.303, 95%CI: 1.653-6.600) as the risk factors for adverse outcomes of PTB in urban patients with PTB-DM, while the treatment/observed management throughout the process (HR=0.470, 95%CI: 0.274-0.803) and fixed-dose combinations throughout the process (HR=0.331, 95%CI: 0.151-0.729) as the protective factors for adverse outcomes in rural patients with PTB-DM.
Conclusions
There are differences in influencing factors for adverse outcomes of PTB in urban and rural patients with PTB-DM. The adverse outcomes of PTB are associated with first diagnosed hospitals and drug resistance in urban patients, and are associated with the treatment/observed management and fixed-dose combinations throughout the process in rural patients.

BACKGROUND:Hydroxy safflower yellow A has anti-ischemia,anti-oxidation,anti-thrombotic and anti-inflammatory effects.Whether it affects neuronal pyroptosis after glucose-oxygen deprivation/reglucose-reoxygenation is still unclear. OBJECTIVE:To investigate the protective effect of hydroxy safflower yellow A on neuronal pyroptosis and its mechanism. METHODS:HT22 cells in logarithmic growth phase were randomly divided into five groups:normal group,model group,hydroxy safflower yellow A group,colivelin group,and colivelin+hydroxy safflower yellow A group.HT22 cells were treated with glucose-oxygen deprivation/reglucose-reoxygenation to establish neuronal pyroptosis model,and then treated with STAT3 agonist Colivelin and hydroxy safflower yellow A.JC-1 probe was employed to assess changes in mitochondrial membrane potential.Reactive oxygen species kit was used to determine the content of reactive oxygen species in cells.GSDMD/TUNEL staining was conducted to observe cell pyroptosis.Immunofluorescence analysis was performed to detect STAT3 and GSDMD protein expression.RT-PCR was utilized for assessing mRNA expression levels of STAT3,NLRP3,and Caspase-1.Western blot assay was utilized to measure the protein expression levels of p-STAT3,NLRP3,GSDMD,Cleaved-caspase-1,and interleukin-1β. RESULTS AND CONCLUSION:(1)Compared with the normal group,the number of pyroptotic cells increased in HT22 cells in the model group along with a significant increase in protein expression levels of p-STAT3,NLRP3,Cleaved-caspase-1,GSDMD,and interleukin-1β.Compared with the model group,the number of pyroptotic cells reduced,and the expression of pyroptosis-related proteins significantly decreased in the hydroxy safflower yellow A group.(2)In comparison with the model group,pyroptosis worsened in the colivelin group where mitochondrial membrane potential decreased along with elevated reactive oxygen species content and increased mRNA expression levels of STAT3,NLRP3,and Caspase-1,as well as increased protein expression levels of p-STAT3,NLRP3,GSDMD,Cleaved-caspase-1,and interleukin-1β.Compared with the Colivelin group,above indexes were improved in the colivelin+hydroxy safflower yellow A group.These results suggest that hydroxy safflower yellow A plays a neuroprotective role through STAT3 signaling pathway to inhibit HT22 pyroptosis after glucose-oxygen deprivation/reglucose-reoxygenation treatment.
