This study aimed to investigate the mechanism of compound Agrimonia pilosula enteritis capsules (CAPEC) on ulcerative colitis (UC) in mice with dampness-heat syndrome. The mice were randomly divided into five groups: the control group, the model group, the positive drug (5-aminosalicylic acid, 5-ASA) group, the low-dose CAPEC (CAPEC-L) group and the high-dose CAPEC (CAPEC-H) group. The mice models were established by using high-fat high-sucrose diet, feeding with distilled spirit and dextran sulfate sodium (DSS). The effects of CAPEC on bile acids (BAs) metabolic profiles in bile and the FXR-SREBP-1 signaling pathway were investigated in the model of UC in mice with dampness-heat syndrome by ELISA, qRT-PCR, UHPLC-QQQ/MS, and histopathological analysis. The results showed that, compared with the model group, the CAPEC-L group and the CAPEC-H group significantly reduced the disease activity index (DAI), and proinflammatory cytokine levels (including IL-6, IL-1β, and TNF-α) in both serum and colon tissues. Additionally, CAPEC markedly ameliorated intestinal inflammation, hepatic lipid accumulation, and pathological alterations in tongue tissue. The CAPEC-H group significantly attenuated the abnormal elevation of BAs profiles in bile, and up-regulated hepatic mRNA levels of Cyp7a1, Cyp7b1, Cyp27a1, Bsep, Fxr, and Shp, while down-regulating Srebp-1 and Cyp8b1 expression. The experimental results suggest that CAPEC alleviates UC with dampness-heat syndrome by ameliorating BAs metabolic disorders, hepatic lipid accumulation, and intestinal inflammation. These findings provide mechanistic insights into CAPEC’s traditional effects of clearing heat and drying dampness, and strengthening the spleen to relieve diarrhea.

Evaluating the absorption of traditional Chinese medicine (TCM) formulations in skin has long been a challenge in cutaneous pharmacokinetic studies of TCM. In recent years, various new techniques, including diffusion cell, microphysiological system, matrix-assisted laser desorption/ionization mass spectrometry imaging, tape stripping, microdialysis/open-flow microperfusion, and confocal Raman microscopy technology, have been developed to characterize and predict the pharmacokinetic profiles of these formulations more accurately. This review systematically summarizes the application progress of these methods in the evaluation of cutaneous pharmacokinetics of TCM, highlights their technical features and suitable scenarios, and discusses future development trends, providing new research perspectives for further understanding the dynamic changes, spatial distribution characteristics of active ingredients in the skin, and the rationality of compatibility in topical preparations.

ObjectiveTo evaluate the efficacy and safety of Janus kinase （JAK） inhibitors combined with Chinese herbal medicine （CHM） in treating rheumatoid arthritis （RA）. MethodsClinical data from 169 RA patients were retrospectively collected. Among them， 71 cases received JAK inhibitors as the control group， while 98 cases received JAK inhibitors plus CHM as the observation group， both treated for 24 weeks. The rheumatoid factor （RF）， cyclic citic peptide antibody （anti-CCP）， erythrocyte sedimentation rate （ESR）， C-reactive protein （CRP）， and white blood cell count （WBC） were recorded before and after treatment. Databases including CNKI， Wanfang， VIP， PubMed and Web of Science were searched from inception till August 31st， 2025 for randomized controlled trials （RCTs） on the combined use of JAK inhibitors and CHM for RA. The methodological quality of the included studies was evaluated using the risk of bias assessment tool. Meta-analyses were performed for RF， anti-CCP， ESR， CRP， 28-joint disease activity score （DAS28）， overall clinical effective rate， and incidence of adverse events. Sensitivity analysis were also performed. ResultsThe retrospective study demonstrated that after treatment， ESR， CRP， and anti-CCP levels decreased in the observation group， while ESR and CRP levels decreased in the control group （P＜0.05）. Moreover， ESR and RF levels in the observation group were lower than those in the control group （P＜0.05）. A total of 9 RCTs involving 770 patients were included in the meta-analysis. The results indicated that the JAK inhibitors plus CHM group was superior to the JAK inhibitors group in reducing RF （MD=-8.97， 95%CI -15.01 to -2.94， P=0.004）， CRP （MD=-3.34， 95%CI -3.82 to -2.86， P＜0.001）， ESR （MD=-5.33， 95%CI -7.98 to -2.69， P＜0.001）， and DAS28 score （MD=-0.54， 95%CI -0.74 to -0.34， P＜0.001）， as well as in improving the overall clinical effective rate （OR=4.53， 95%CI 2.55 to 8.03， P＜0.001）. No statistically significant differences were observed between groups in anti-CCP levels （SMD=-2.08， 95%CI -4.41 to 0.24， P=0.080） or incidence of adverse events （OR=0.93， 95%CI 0.55 to 1.57， P=0.790）. ConclusionThe combination of JAK inhibitors and CHM demonstrates remarkable efficacy in treating RA， contributing to improved disease activity and reduced inflammatory markers with a favorable safety profile.

Objective:To evaluate the clinical efficacy and safety of an antioxidant gel containing tea polyphenols combined with narrow-band ultraviolet B in the treatment of vitiligo.Methods:A single-center, randomized controlled clinical trial was conducted. From April 25 to June 27, 2024, patients with vitiligo were selected from the Department of Dermatology, Hangzhou Third People's Hospital. An open-label and researcher-blinded design was used. The patients were divided into 3 groups: a phototherapy group receiving phototherapy alone, a tea polyphenols combined group treated with an antioxidant gel containing tea polyphenols combined with phototherapy, and a positive control group treated with an antioxidant gel containing superoxide dismutase combined with phototherapy, with the treatment duration being 3 months. The efficacy was evaluated using the Vitiligo Area Scoring Index (VASI), and when the VASI was improved by ≥ 10%, the treatment would be considered effective. Changes in skin aging and skin barrier function indicators before and after treatment were assessed for 72 vitiligo lesions in the tea polyphenols combined group and for 72 lesions in the phototherapy group. Comparisons between the groups were performed using one-way analysis of variance, Fisher's exact test, chi-square test, or t test. Results:A total of 171 vitiligo patients with 307 target lesions were successfully followed up in this study, including 74 males and 97 females, and their ages ranged from 1 to 64 years. Among the 307 lesions, 95 were treated with phototherapy alone, of which 35 showed improvement, resulting in a total response rate of 36.8% and an average VASI improvement rate of 10.9%; adverse reactions occurred in 29 lesions (30.5%). Of 138 lesions treated with the antioxidant gel containing tea polyphenols combined with phototherapy, 73 showed improvement, resulting in a total response rate of 52.9% and an average VASI improvement rate of 24.0%; adverse reactions occurred in 10 lesions (7.2%). In the positive control group, 74 lesions were treated, and 40 showed improvement, resulting in a total response rate of 54.1% and an average VASI improvement rate of 18.3%; adverse reactions occurred in 5 lesions (6.8%). Compared with the phototherapy group, the tea polyphenols combined group showed a significantly increased total response rate and a VASI improvement rate (both P < 0.01), but a significantly decreased incidence rate of adverse reactions ( P < 0.001). No significant differences in the above indicators were observed between the tea polyphenols combined group and the positive control group (all P > 0.05). In addition, the changes in skin barrier function and skin aging indicators (except for wrinkle depth) before and after treatment were significantly reduced in the tea polyphenols combined group compared to the phototherapy group (all P < 0.05). After the phototherapy alone, the transepidermal water loss significantly increased ( P = 0.004), and the water content of the stratum corneum significantly decreased ( P = 0.012). However, no significant differences in skin barrier function or skin aging indicators were found between pre- and post-treatment in the tea polyphenols combined group ( P > 0.05) . Conclusion:The antioxidant gel containing tea polyphenols could effectively improve the efficacy of narrow-band ultraviolet B in the treatment of vitiligo, and alleviate skin aging and barrier damage caused by phototherapy.

Pyroptosis is a form of programmed cell death that differs from classical apoptosis and passive necrosis.It plays a crucial role in activating innate immune responses,driving local inflam-matory reactions,regulating immune cell activation and infiltration,and remodeling the tumor immune microenvironment.In recent years,the role of pyroptosis in the initiation,progression,and treatment response of urological tumors has garnered increasing attention.Current studies have demonstrated that pyroptosis exhibits dual regulatory effects in various tumors:on the one hand,it exerts anti-tumor effects by inducing lytic death of tumor cells;on the other hand,under specific microenvironmental conditions,the chronic inflammatory response mediated by pyroptosis may promote immune escape,thereby driving tumor progression.This review systematically summarized the similarities and differ-ences in the molecular mechanisms of pyroptosis in three common urological tumors,namely renal cell carcinoma,bladder cancer,and prostate cancer.It also summarized the regulatory networks and po-tential therapeutic targets during tumor initiation and progression.Furthermore,it elucidated the re-search progress on enhancing the efficacy of immune checkpoint inhibitors by modulating pyroptosis pathways,aiming to provide novel strategies and theoretical foundations for the precise treatment of u-rological.

The cooccurrence of NPM1, FLT3-ITD, and DNMT3A mutations (i.e., triple mutation) is related to dismal prognosis in patients with acute myeloid leukemia (AML) receiving chemotherapy alone. In this multicenter retrospective cohort study, we aimed to identify whether allogeneic hematopoietic stem cell transplantation (allo-HSCT) could overcome the poor prognosis of DNMT3A^mutNPM1^mutFLT3-ITD^mut AML across four transplant centers in China. Fifty-three patients with triple-mutated AML receiving allo-HSCT in complete remission were enrolled. The 1.5-year probabilities of relapse, leukemia-free survival, and overall survival after allo-HSCT were 11.9%, 80.3%, and 81.8%, respectively. Multivariate analysis revealed that more than one course of induction chemotherapy and allo-HSCT beyond CR1 were associated with poor survival. To our knowledge, this work is the largest study to explore the up-to-date undefined role of allo-HSCT in patients with triple-mutated AML. Our real-world data suggest that allo-HSCT could overcome the poor prognosis of DNMT3A^mutNPM1^mutFLT3-ITD^mut in AML.

Objective:To explore the application effect of a hierarchical training model based on the "geese formation effect" in the professional training of gastrointestinal center nurses.Methods:A total of 122 nurses at the Gastrointestinal Center of West China Hospital, Sichuan University, were randomly divided into an experimental group ( n=61) and a control group ( n=61). The experimental group received a hierarchical training model based on the "geese formation effect". Nurses in this group were divided into four levels of N1 to N4 according to seniority, corresponding to the roles of "young geese", "growing geese", "flying geese", and "leading geese/flying geese", and differentiated training content and formats were implemented. The control group received routine training. At the end of the training and at 3 and 6 months after the training, theoretical knowledge and operational skills were assessed, along with evaluations of job competency, professional characteristic indicators, and teaching satisfaction. The chi-square test and independent samples t-test were performed using SPSS 25.0. Results:At the end of the training and at 3 and 6 months after the training, compared with the control group, the experimental group achieved significantly higher scores in theoretical knowledge [(91.69±3.04) vs. (83.66±6.35), (89.42±3.29) vs. (81.33±5.79), (85.63±3.67) vs. (76.59±6.48)] and operational skills [(92.20±2.54) vs. (82.95±6.09), (90.15±2.83) vs. (81.61±5.47), (89.24±3.18) vs. (78.91±5.89)] (all P<0.001). The total score of job competency in the experimental group was higher than that in the control group. For the professional characteristic indicators, the experimental group also outperformed the control group in the implementation rate of postoperative pressure ulcer prevention (90.16% vs. 72.13%) and the ERAS compliance rate (93.44% vs. 80.33%) (both P<0.05). The total score of training satisfaction was higher in the experimental group than in the control group. Conclusions:The hierarchical training model based on the "geese formation effect" can effectively improve the theoretical knowledge, operational skills, job competency, and clinical nursing quality of nurses, with high teaching satisfaction and promotion value.
