OBJECTIVE To confirm trigger items for adverse drug reaction (ADR) induced by bevacizumab, to identify and analyze the occurrence of related ADR, and to establish a predictive model for severe adverse reaction (SAR) caused by this drug. METHODS Based on the global trigger tool (GTT) theory, and referencing the GTT White Paper, drug package inserts and relevant literature, trigger items for bevacizumab-related ADR were confirmed using a single-round Delphi method. Utilizing these established items, electronic medical records of relevant patients at Guilin People’s Hospital from January 2020 to September 2024 were actively screened via the China Hospital Pharmacovigilance System. Pharmacists then identified and tallied the occurrence of bevacizumab-induced ADR. Data from patients with any positive trigger item served as the study subjects (divided into training and test sets at a ratio of 7∶3), candidate feature variables were selected from 39 related variables using the Boruta algorithm, and the multivariable Logistic regression analysis was performed with the occurrence of SAR as the dependent variable. Based on these candidate features, Logistic Regression, Extreme Gradient Boosting, Light Gradient Boosting Machine, Random Forest, and Categorical Boosting models were constructed. Model performance was evaluated using metrics including the area under the curve (AUC) of receiver operating characteristic curve and recall rate. The Shapley Additive exPlanations (SHAP) method was applied to analyze and interpret the contribution of each variable. A nomogram was constructed based on the optimal model. RESULTS A total of 38 trigger items for active monitoring of bevacizumab-related ADR were determined, comprising 17 laboratory indicators, 13 clinical manifestations, and 8 intervention measures. In total, 483 patients with positive trigger items were included, and 318 patients with bevacizumab-induced ADR were identified, including 83 SARs. The positive predictive values for the trigger items and cases were 43.57% (708/1 625) and 63.84% (318/483), respectively. Bevacizumab-induced ADR involved 7 systems/organs, with the hematological system being the most frequently involved (64.15%). The Boruta algorithm selected 7 vari ables: serum potassium, hematocrit, albumin-to-globulin ratio, prealbumin, hypertension history, age and red blood cell count. Multivariable Logistic regression showed that elevated serum potassium levels were associated with a decreased risk of bevacizumab-induced SAR (OR=0.234, P =0.002), while a history of hypertension (OR=2.642, P =0.006) and increased age (OR=1.040, P =0.025) were associated with an increased risk. The Logistic Regression model demonstrated superior performance with higher AUC, F1 score and recall rate (0.761, 0.447, 0.607), compared to other models. SHAP evaluation results indicated that variables such as serum potassium, hematocrit, and age ranked highest in importance. CONCLUSIONS Totally 38 trigger entries have been successfully identified for active screening of bevacizumab-related ADR. Elevated serum potassium levels are a protective factor against bevacizumab-induced SAR, whereas the hypertension history and increased age are risk factors. The Logistic Regression model is the optimal predictive model.

OBJECTIVE To evaluate the effect of clinical pharmacists participating in the treatment of chronic heart failure (CHF) based on the clinical pharmacy pathway (CPP). METHODS Totally 226 CHF patients recruited from August 24th, 2024 to March 14th, 2025, were divided into an observation group and a control group based on the random number table method, with 113 cases in each group. All patients were treated with conventional therapy. The observation group was additionally given CPP management (including pharmaceutical care during hospitalization, the formulation of individualized discharge medication regimens, and pharmaceutical follow-up after discharge). The cardiac function parameters at admission, at discharge, at 3 and 6 months after discharge, drug use at 6 months after discharge, economic indicators, as well as the readmission rate and mortality rate at 6 months after discharge were compared between the two groups. Morisky Medication Adherence Scale-8 Items (MMAS-8), Somatic Self-rating Scale (SSS) and Patient Health Questionnaire-9 (PHQ-9) scores were compared at admission, at discharge and at 3 and 6 months after discharge. RESULTS Six months after discharge, 24 patients dropped out. Eventually, 104 patients in the observation group and 98 patients in the control group completed the study. Compared with at admission, New York Heart Association (NYHA) cardiac functional classification, left ventricular ejection fraction (LVEF) and N -terminal pro-B-type natriuretic peptide (NT-proBNP) of both groups of patients at discharge as well as at 3 and 6 months after discharge were significantly improved; moreover, the improvements at 3 and 6 months after discharge were significantly better than those at discharge. Meanwhile, the above indexes (except for NYHA cardiac functional classification at discharge, NT-proBNP and NYHA cardiac functional classification at 3 months after discharge) of the observation group at discharge, at 3 and 6 months after discharge were significantly better than the control group ( P <0.05). The utilization rates of angiotensin converting enzyme inhibitor (ACEI)/angiotensin Ⅱ receptor blocker (ARB)/angiotensin receptor neprilysin inhibitor (ARNI), the proportion of β-blockers reaching the target dose, the utilization rate of sodium-glucose linked transporter 2 inhibitor (SGLT2i), and the proportion of SGLT2i reaching the target dose in the observation group were significantly higher than the control group ( P <0.05), and the proportion of drugs and readmission rate were significantly lower than the control group ( P <0.05). Compared with at admission, MMAS-8 scores of the patients in the observation group at discharge, at 3 and 6 months after discharge were significantly increased, while SSS and PHQ-9 scores were significantly lowered ( P <0.05). And all the above scores gradually decreas ed with the extension of discharge time ( P <0.05). CONCLUSIONS Clinical pharmacists can utilize CPP to significantly improve patients’ cardiac function, medication adherence, somatic symptoms and depression. Additionally, they can significantly improve the utilization rates of ACEI/ARB/ARNI and SGLT2i, as well as the proportion of target doses of β-blockers and SGLT2i, while simultaneously reducing readmission rates.

Objective:
To systematically evaluate the therapeutic efficacy and maintenance effects of digital psychological therapies on depressive symptoms among adolescents, so as to provide a reference for clinical practice.
Methods:
Randomized controlled trial(RCT) investigating digital psychological therapies to improve depressive symptoms among adolescents were searched across databases, including PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang database, VIP database, and SinoMed, from database inception to November 20, 2025. Following literature screening, quality assessment, and data extraction, a Meta analysis was performed using Stata 18.0 software.
Results:
A total of 20 studies involving 2 042 adolescents aged 11-19 were included. The Meta analysis revealed that digital psychological therapies significantly alleviated depressive symptoms in adolescents ( SMD =-0.59, 95% CI =-0.85 to -0.32, P <0.01). The therapeutic effect was sustained at long term follow up ( SMD =-0.21, 95% CI =-0.34 to -0.09, P <0.01). Furthermore, depression scores in the intervention group showed a continued decrease from post intervention to long term follow up ( SMD =-0.28, 95% CI =-0.41 to -0.14, P <0.01). Egger s linear regression test indicated possible publication bias (Kendall s tall=0.28, P <0.01).
Conclusions
Digital psychological therapies can effectively improve depressive symptoms among adolescents, with stable long term efficacy. However, current evidence remains limited and exhibits substantial heterogeneity. Therefore, further large sample, high quality RCTs are warranted to validate the effectiveness of this intervention.

ObjectiveTo explore the effect of transcutaneous electrical acupoint stimulation (TEAS) on stress response in patients undergoing unilateral biportal endoscopy (UBE) and to identify optimal TEAS parameters. MethodsA total of 96 patients undergoing UBE were randomly grouped into total intravenous anesthesia (TIVA) group, acupuncture-assisted anesthesia with continuous waves (AACW) group, and acupuncture-assisted anesthesia with sparse-dense waves (AASDW) group, with 32 patients per group. All groups were given a standardized TIVA protocol. In the AACW group (100 Hz continuous wave stimulation) and the AASDW group (2/100 Hz sparse-dense wave stimulation), TEAS intervention was applied to both bilateral Zusanli (ST36) and Sanyinjiao (SP6) 30 minutes before TIVA induction and continued until the end of the surgery. In the TIVA group, electrodes were only connected without electrical stimulation. The stress response indicators including cortisol (Cor) and adrenocorticotropic hormone (ACTH), heart rate (HR), mean arterial pressure (MAP), and bispectral index (BIS) at before anesthesia induction (T0), after tracheal intubation (T1), during laminectomy (T2), and 1 hour after surgery (T3) were compared across groups. The operation duration, anesthesia duration, extubation and recovery duration were recorded, as well as pain intensity including visual analogue scale (VAS), and sedation level (by Ramsay sedation score) at 2, 6, 12 hours after surgery, and postoperative complications. ResultsThe AACW group and AASDW group had lower ACTH and COR levels at T1, T2 and T3, as well as lower HR and MAP levels at T1 and T2 than TIVA group, with AASDW group being lower than AACW group (P<0.05). At T3, the AASDW group had higher BIS than TIVA group and AACW group (P<0.05). No significant difference in operation duration was observed (P>0.05). The AACW group and AASDW group had shorter anesthesia, extubation and recovery duration than TIVA group, with AASDW group being the shortest (P<0.05). The VAS scores at 2 h, 6 h, and 12 h after surgery in the AACW and AASDW groups were lower than those in the TIVA group, with the AASDW group showing significantly lower scores than the AACW group (P<0.05). The Ramsay sedation scores in the AASDW group were lower than those in the AACW group at 2 h and 6 h after surgery (P<0.05). The total incidence of complications in the AASDW group was 6.25% (2/32), significantly lower than 28.13% (9/32) in the TIVA group (P<0.05). ConclusionTEAS can effectively suppresses stress response in patients undergoing UBE, with the 2/100 Hz sparse-dense wave parameter being most effective, which can stabilize hemodynamics, accelerate recovery, improve postoperative sedation and analgesia quality, and reduces complications.

ObjectiveTo explore the mechanism by which Qiangjing tablets (QJT) alleviate the spermatogenic function damage caused by varicocele (VC) based on the Kelch-like ECH-associated protein 1 (Keap1)/nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway-mediated oxidative stress. MethodsTen Sprague-Dawley (SD) rats were randomly assigned into a control group and a model group. Pathological examination confirmed the stability of the model. Thirty-six SD rats were randomized into control, model, low-dose (0.23 g·kg-1) QJT, medium-dose (0.46 g·kg-1) QJT, high-dose (0.92 g·kg-1) QJT, and mazhilin (61.7 mg·kg-1) groups, with 6 rats in each group. A rat model of experimental left varicocele (ELV) was established by partially ligating the left renal vein to simulate the human nutcracker syndrome. The rats were administrated with corresponding agents once a day for 28 consecutive days. The in vitro testicular culture model of rats was established through the Transwell chamber method and intervened with QJT-containing sera (2.3, 4.6, and 9.2 g·kg-1). Microscopic observation was carried out for the morphology of the left kidney. A micrometer was used to measure the diameter of the left spermatic vein (LSV). The body weights of rats were recorded weekly, and the epididymis and testis weights were measured. The pathological changes of the testicular tissue was observed via hematoxylin-eosin (HE) staining. The levels of testosterone (T) in the cell culture supernatant and reactive oxygen species (ROS) in the rat testicular tissue were measured by enzyme-linked immunosorbent assay (ELISA). Flow cytometry was employed to determine the ROS content. Immunohistochemical staining was conducted to analyze Keap1, Nrf2, 3β-hydroxysteroid dehydrogenase (3β-Hsd), GATA-binding protein-4 (Gata-4), and proto-oncogene receptor tyrosine kinase (C-kit). The ultrastructure of the tissue was observed by transmission electron microscopy (TEM). Cell apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) staining. The expression of Keap1, Nrf2, glutathione S-transferase α2 (Gsta2), glutathione S-transferase μ1 (Gstm1), heme oxygenase-1 (HO-1), quinone oxidoreductase 1 (Nqo1), and thioredoxin reductase 1 (Txnrd1) was quantified by Real-time quantitative polymerase chain reaction(Real-time PCR) and Western blot. ResultsCompared with the control group, the ROS content and the percentage of apoptotic cells in the model group were significantly increased (P<0.01), the T concentration was significantly decreased (P<0.01), the mRNA and protein expressions of Keap1 were significantly increased (P<0.01), and the mRNA and protein expressions of Nrf2, Gsta2, Gstm1, HO-1, Nqo1 and Txnrd1 were significantly decreased (P<0.05). Compared with the model group, the ROS content and the percentage of apoptotic cells in each dose group of the Qiangjing Tablets were significantly reduced (P<0.05), and the mRNA and protein expressions of Keap1 were significantly decreased (P<0.05), while the mRNA and protein expressions of Nrf2, Gsta2, Gstm1, HO-1, Nqo1 and Txnrd1 were significantly increased (P<0.05). ConclusionQJT improves sperm motility in the rat model of VC by modulating the Keap1/Nrf2 signaling pathway and reducing oxidative stress injury.

AIM:To analyze the influencing factors of visual outcome after vitrectomy for polypoidal choroidal vasculopathy(PCV)combined with vitreous hemorrhage and establish a predictive model.METHODS: A retrospective analysis was conducted on the clinical data of 129 cases(129 eyes)of patients who underwent vitrectomy for PCV combined with vitreous hemorrhage from June 2021 to January 2024 in our hospital. They were divided into elevated group(71 eyes)and non-elevated group(58 eyes)according to visual outcome at early posoperative stage(within 24 mo). Another 30 cases(30 eyes)of PCV with vitreous hemorrhage undergoing vitrectomy were selected as external validation data. The predictive value of the model for the postoperative visual outcomes of both internal and external populations was evaluated.RESULTS: The non-elevated group had a higher proportion of patients aged ≥60 years, diabetes, continuous abnormalities of the ellipsoid zone(EZ)during surgery, bleeding involving the macular fovea, and postoperative retinal scar formation than the elevated group were independent factors affecting postoperative visual acuity(all P<0.05). The AUC of the predictive model for predicting the postoperative visual outcomes of internal and external populations was 0.824(95%CI: 0.750-0.898)and 0.809(95%CI: 0.723-0.865), respectively.CONCLUSION:Patients aged ≥60 years, diabetes, intraoperative continuous abnormalities of EZ, bleeding involving the macular fovea, and postoperative retinal scar formation are influencing factors for visual outcome after vitrectomy in patients with PCV combined with vitreous hemorrhage. A predictive model based on those factors has been established, which has a certain predictive value for postoperative visual outcome.

Objective: To analyze the serological characteristics of anti-Mur antibodies and investigate the distribution frequency of the Mur antigen among voluntary blood donors in Shiyan, thereby providing a basis for guiding clinical transfusion and establishing a Mur blood type database. Methods: ABO blood grouping of donors and patients was performed using an automated blood typing analyzer and the gel card method, respectively. Unexpected antibody screening and identification were performed using the saline, tube anti-human globulin, and polybrene methods. The specificity of anti-Mur antibodies was confirmed using Fisher's exact probability test. Plasma treated with 2-mercaptoethanol was used to distinguish IgM and IgG antibodies. IgM and IgG anti-Mur titers were determined by the saline tube method and the anti-human globulin tube method, respectively, at 4℃, room temperature, and 37℃. A total of 1 659 donor red blood cell samples were initially screened for the Mur antigen phenotype using three samples of human-derived anti-Mur plasma by the micro-tube method. Donors who tested positive for Mur antigen were further tested by the direct antiglobulin test (DAT); those with negative results were confirmed for Mur antigen by the gel card and polybrene methods. Results: Three blood samples were identified to contain mixed IgG and IgM anti-Mur antibodies. The titers of both IgM and IgG anti-Mur antibodies were highest at 4℃, intermediate at room temperature, and lowest at 37℃. The positive frequency of the Mur antigen among voluntary blood donors in Shiyan was 1.99% (33/1 659). Conclusion: anti-Mur antibodies were detected in both blood donors and patients in our region. The Mur antigen shows a certain distribution frequency among voluntary blood donors in Shiyan. Screening for the Mur blood type and establishing a corresponding database could enhance transfusion safety.

Traditional Chinese medicine formula (TCMF) represents a fundamental component of Chinese medical practice, incorporating medical knowledge and practices from both Han Chinese and various ethnic minorities, while providing comprehensive insights into health and disease. The foundation of TCMF lies in its holistic approach, manifested through herbal compatibility theory, which has emerged from extensive clinical experience and evolved into a highly refined knowledge system. Within this framework, Chinese herbal medicines exhibit intricated characteristics, including multi-component interactions, diverse target sites, and varied biological pathways. These complexities pose significant challenges for understanding their molecular mechanisms. Contemporary advances in artificial intelligence (AI) are reshaping research in traditional Chinese medicine (TCM), offering immense potential to transform our understanding of the molecular mechanisms underlying TCMFs. This review explores the application of AI in uncovering these mechanisms, highlighting its role in compound absorption, distribution, metabolism, and excretion (ADME) prediction, molecular target identification, compound and target synergy recognition, pharmacological mechanisms exploration, and herbal formula optimization. Furthermore, the review discusses the challenges and opportunities in AI-assisted research on TCMF molecular mechanisms, promoting the modernization and globalization of TCM.

In current clinical practice, various dermal templates and skin substitutes are used to enhance wound healing. However, the role of wound commensal microbiome in regulating scaffold performance and the healing process remains unclear. In this study, we investigated the influence of both natural and synthetic scaffolds on the wound commensal microbiome and wound repair in three distinct models including diabetic wounds, burn injuries, and germ-free (GF) wounds. Remarkably, synthetic electrospun polycaprolactone (PCL) scaffolds were observed to positively promote microbiome diversity, leading to enhanced diabetic wound healing compared to the natural scaffolds Integra® (INT) and MatriDerm® (MAD). In contrast, both natural and synthetic scaffolds exhibited comparable effects on the diversity of the microbiome and the healing of burn injuries. In GF wounds with no detectable microorganisms, a reversed healing rate was noted showing natural scaffold (MAD) accelerated wound repair compared to the open or the synthetic scaffold (PCL) treatment. Furthermore, the response of the wound commensal microbiome to PCL scaffolds appears pivotal in promoting anti-inflammatory factors during diabetic wound healing. Our results emphasize that the wound commensal microbiome, mediated by different scaffolds plays an important role in the wound healing process.

Intestinal fibrosis is a significant clinical challenge in inflammatory bowel diseases, but no effective anti-fibrotic therapy is currently available. Glucagon receptor (GCGR) and glucagon-like peptide 1 receptor (GLP1R) are both peptide hormone receptors involved in energy metabolism of epithelial cells. However, their role in intestinal fibrosis and the underlying mechanisms remain largely unexplored. Herein GCGR and GLP1R were found to be reduced in the stenotic ileum of patients with Crohn's disease as well as in the fibrotic colon of mice with chronic colitis. The downregulation of GCGR and GLP1R led to the accumulation of the metabolic byproduct lactate, resulting in histone H3K9 lactylation and exacerbated intestinal fibrosis through epithelial-to-mesenchymal transition (EMT). Dual activating GCGR and GLP1R by peptide 1907B reduced the H3K9 lactylation in epithelial cells and ameliorated intestinal fibrosis in vivo. We uncovered the role of GCGR/GLP1R in regulating EMT involved in intestinal fibrosis via histone lactylation. Simultaneously activating GCGR/GLP1R with the novel dual agonist peptide 1907B holds promise as a treatment strategy for alleviating intestinal fibrosis.
