ObjectiveThis study aims to systematically review the marketed traditional Chinese patent medicines for treating chronic gastritis （CG） in China. By analyzing their variety characteristics and prescription patterns， it seeks to provide references for clinical syndrome differentiation-based drug selection， treatment method optimization， and the design of high-quality clinical research. MethodsInformation on marketed traditional Chinese patent medicines for treating CG was collected. Microsoft Excel software was used to collate and statistically analyze representative drugs for each pathological stage， market status， syndrome types， and other contents. The Ancient and Modern Medical Case Cloud Platform （V2.3.9） was employed to analyze the formula composition patterns of standardized prescriptions. ResultsA total of 141 marketed traditional Chinese patent medicines for treating CG in China were included. Based on the disease's pathological progression， they can be classified into drugs for non-atrophic gastritis， atrophic gastritis， and precancerous lesions. Post-marketing research reveals that relevant evaluation is only conducted on 17 drugs， of which 2 involve pharmacoeconomic studies and 14 possess standardized evidence-based evidence. The primary dosage forms were capsules， granules， and tablets. From the 100 prescriptions screened according to inclusion/exclusion criteria， the varieties indicated for the stomach collateral stasis syndrome in atrophic gastritis accounted for the highest proportion. The main efficacy distributions were clearing heat， detoxifying， and relieving pain by promoting Qi circulation. Core drugs included Glycyrrhizae Radix et Rhizome， Paeoniae Radix Alba， and Aucklandiae Radix. Medicinal properties were predominantly warm and neutral. Flavors were mainly bitter， pungent， and sweet. The drugs primarily entered the spleen and stomach meridians. Analysis of the package inserts reveals that 67 products list "contraindications"， 110 include "precautions"， and 23 explicitly state "adverse reactions". ConclusionTraditional Chinese patent medicines for treating CG hold unique value in clinical practice. However， currently there are challenges such as insufficient clarity in syndrome type descriptions within package inserts and a relative lack of high-level evidence-based medical evidence， as well as pharmacoeconomic evaluations. Future efforts should focus on addressing these shortcomings by advancing research on syndrome characteristics and medication patterns based on syndrome differentiation， systematically conducting pharmacoeconomic evaluations， strengthening the accumulation of high-level evidence-based evidence， and， on this basis， improving patient medication adherence. This will comprehensively enhance the clinical application value and scientific connotation of this category of drugs.

Purpose: This study aimed to develop and evaluate the effectiveness of the Trauma-nursing Education and Skill Support (TESS) program based on the ADDIE model (Analysis, Design, Development, Implementation, Evaluation model). The program was designed to enhance trauma nurses’ clinical competencies, including trauma-related knowledge, self-efficacy, and problem-solving ability, through the integration of theoretical education and simulation-based practice. Methods: A quasi-experimental study using a non-equivalent control group pretest–posttest design was conducted. Participants included 108 trauma nurses from regional trauma centers, military trauma centers, and emergency care facilities, who were assigned to an experimental group (n=52) or a control group (n=56). The TESS program consisted of a 2-day, 14-hour blended-learning course that included eight lecture sessions and four simulation-based practice stations. Data were collected at baseline, immediately after the intervention, and at 6 months using validated instruments measuring trauma-related knowledge, self-efficacy, and problem-solving ability. Two-way repeated-measures analysis of variance was used for data analysis. Results: The experimental group demonstrated significant improvements in trauma-related knowledge, self-efficacy, and problem-solving ability compared with baseline (all p<.001). These improvements were sustained at 6 months, although trauma-related knowledge scores showed a slight decline compared with immediate posttest levels. Between-group analyses confirmed significant group-by-time interaction effects for all outcomes: trauma-related knowledge (η2=0.12, p<.001), self-efficacy (η2=0.09, p=.002), and problem-solving ability (η2=0.08, p=.003). Conclusion The TESS program effectively enhanced trauma nurses’ trauma-related knowledge, self-efficacy, and problem-solving ability, with effects sustained for up to 6 months. Incorporating blended learning and simulation-based training into standardized trauma nursing education may strengthen clinical competencies and ultimately contribute to improved patient outcomes.

The Pheochromocytoma of the Adrenal Gland Scaled Score (PASS) is widely used for risk stratification in pheochromocytoma and paraganglioma (PPGL), but its clinical utility is limited by inter-observer variability of its parameters and inconsistent predictive performance. Methods: We conducted a multicenter retrospective study of 1,518 patients with PPGL from five tertiary referral centers in Korea. Prognostic utility of PASS system was assessed using logistic regression, Kaplan-Meier analysis, and receiver operating characteristic (ROC) curve analysis. Inter-observer variability was inferred by comparing area under the ROC curve (AUCs) across institutions. Simplified PASS systems were developed based on multivariable analysis of key histopathological parameters. Results: The PASS system was a significant predictor of adverse events and recurrence-free survival. Although the PASS system demonstrated only modest discriminative ability (AUC, 0.673), it showed a high negative predictive value (NPV, 0.885), supporting its usefulness as a screening tool for benign behavior. However, there was significant inter-institutional variability in PASS performance (AUC; range, 0.513 to 0.727; p < .05). The 3-factor Simple PASS, which incorporates necrosis, spindling, and mitotic figures, exhibited less inter-observer variation. The 4-factor Simple PASS, which adds vascular invasion to the 3-factor model, also showed reduced inter-observer variability and improved AUC and NPV compared to the original PASS system. Conclusions: In this multicenter cohort, the PASS system demonstrated high NPV and screening potential, but significant inter-observer variability remains a challenge. Simplification of the PASS system and enhanced pathologist training may improve reproducibility and clinical utility in PPGL risk stratification.

Purpose: The aim of this study is to summarize cancer risk among patients with clinical indications of immunosuppressive and antineoplastic drugs in Korea, which are pharmaceuticals defined as group 1 by International Agency for Research on Cancer. Materials and Methods: We conducted a nationwide population-based retrospective cohort study using the Korean National Health Insurance Service claims data from 2002 to 2018. Patients with clinical indications for group 1 pharmaceuticals from 2002 to 2017 were selected as baseline population, and followed up until 2018. Cox proportional hazards regression model was used to analyze the risk of cancer and dose-response relationship between group 1 pharmaceuticals and cancer. Results: Azathioprine use increased the risk of skin and hematologic cancer (hazard ratio [HR], 4.63; 95% confidence interval [CI], 2.91 to 7.39 and HR, 3.15; 95% CI, 2.41 to 4.13). Cyclosporine use increased the risk of skin and hematologic cancer (HR, 2.30; 95% CI, 1.79 to 2.95 and HR, 2.96; 95% CI, 2.59 to 3.40). Cyclophosphamide use increased the risk of bladder and hematologic cancer (HR, 2.69; 95% CI, 1.92 to 3.78 and HR, 3.83; 95% CI, 3.20 to 4.59). Chlorambucil use increased the risk of hematologic cancer (HR, 3.51; 95% CI, 2.53 to 4.87) and melphalan use increased the risk of hematologic cancer (HR, 16.31; 95% CI, 13.41 to 19.85). Methoxsalen use increased the risk of skin cancer (HR, 2.32; 95% CI, 1.36 to 3.95). Conclusion Group 1 pharmaceuticals were associated with increased risk of cancer. The results are expected to help establish alternative clinical strategies and policies for patients with clinical indications of group 1 pharmaceuticals, by continuous risk analysis and discussions on the surveillance systems.

Purpose: To develop the 2025 update to the Korean colorectal cancer (CRC) screening guidelines by systematically evaluating recent evidence, integrating domestic data, and addressing changes since the 2015 guideline revision, thereby providing an evidence-based standard for clinicians and policymakers. Methods: A multidisciplinary committee developed the guidelines using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology. The process included formulation of three key questions addressing screening efficacy, diagnostic accuracy, and optimal screening age and interval. A systematic review of international guidelines and primary literature was conducted, yielding 327 eligible studies. In addition, a utility-based analysis using a Markov model was performed to determine optimal screening ages and intervals. Results: The evidence synthesis identified high-certainty evidence supporting the use of the fecal immunochemical test (FIT) for reducing CRC mortality and moderate-certainty evidence for colonoscopy. Evidence for computed tomographic colonography (CTC) and stool DNA testing was rated as very low certainty. Based on the evidence review and cost-utility analysis, the committee conditionally recommends CRC screening for asymptomatic, average-risk adults aged 45–74 years using either colonoscopy every 10 years or FIT every 1–2 years. CTC and stool DNA testing were not recommended owing to insufficient evidence. Conclusion The 2025 Korean Guidelines for Colorectal Cancer Screening present updated, evidence-based recommendations tailored to the domestic healthcare context. By conditionally endorsing both colonoscopy and FIT for individuals aged 45–74 years, these guidelines aim to improve population-level screening effectiveness and reduce the burden of CRC in South Korea.

ObjectiveTo systematically characterize the in vitro chemical constituents of Entada phaseoloides and its absorbed prototype compounds and metabolites in a neuropathic pain （NP） model， thereby elucidating the potential pharmacological material basis underlying its analgesic activity. MethodsUltra-high-performance liquid chromatography coupled with quadrupole-Orbitrap high-resolution mass spectrometry （UHPLC-Q-Orbitrap HRMS） was used to analyze the constituents of the 80% methanol extract of E. phaseoloides. Thirty-six mice were divided into a blank group， low-， medium-， and high-dose E. phaseoloides extract groups （25， 50， and 100 mg·kg^-1， respectively）， an aspirin group （400 mg·kg^-1）， and a morphine group （10 mg·kg^-1）， with six mice in each group. The tail-flick threshold was measured. Twenty-four mice were randomly divided into a blank group and low-， medium-， and high-dose E. phaseoloides extract groups （25， 50， and 100 mg·kg^-1， respectively）， with six mice in each group， and motor coordination was evaluated. A spinal nerve ligation （SNL） model was established in mice. Twenty-four mice were randomly divided into a sham-operated （Sham） group， an SNL group， an SNL + E. phaseoloides extract group （750 mg·kg^-1）， and an SNL + pregabalin group （20 mg·kg^-1）， with 6 mice in each group. Mechanical allodynia and thermal hyperalgesia were evaluated. Behavioral assessments were combined to determine the optimal onset time of the analgesic effect， and plasma samples were collected at this time point. Absorbed components and metabolites were systematically identified based on accurate mass， MS/MS fragmentation patterns， retention time， and comparisons with literature data and reference standards. Meanwhile， network pharmacology， target similarity analysis， and molecular docking validation were integrated to evaluate the potential effects of absorbed components on disease intervention. ResultsCompared with the blank group， the high-dose E. phaseoloides extract group and morphine group showed significantly increased pain response thresholds （P<0.01）， without affecting motor coordination in normal mice. Compared with the Sham group， the SNL group exhibited significantly decreased thresholds for mechanical allodynia and thermal hyperalgesia （P<0.01）. Compared with the SNL group， the SNL + E. phaseoloides extract group and SNL + pregabalin group showed significantly increased thresholds for mechanical allodynia and thermal hyperalgesia （P<0.01）. The analgesic effect of E. phaseoloides was most significant at 2 h after administration. A total of 70 constituents were identified in vitro， and 22 prototype compounds and 29 metabolites were detected in plasma. The targets of the absorbed components were mainly enriched in biological processes associated with pain signal perception and transmission and showed a high degree of overlap with disease genes related to neuropathic pain. In addition， multiple components exhibited strong binding energies with core pain-related targets. Based on integrated analysis of in vitro content， plasma exposure levels， and target associations， ketanthamide A-β-D-pyranoside and ketengzide were identified as the most representative pharmacologically active substances responsible for the analgesic effect. ConclusionThis study systematically elucidates the material basis of E. phaseoloides intervention in neuropathic pain from three aspects， including chemical constituent characteristics， in vivo behavioral characteristics， and potential targets， providing important theoretical foundations and experimental support for further studies on its pharmacological mechanism and analgesic drug development.

OBJECTIVE To evaluate the efficacy and safety of second-line treatment regimens for human epidermal growth factor receptor 2 （HER2）-positive advanced gastric cancer.METHODS Phase Ⅲ randomized controlled trials（RCTs） about second-line treatment regimens for HER2-positive advanced gastric cancer patients were retrieved from PubMed， CNKI， and other Chinese and English databases. The search period spanned from the inception to April 1， 2026. After screening the literature， extracting data， and assessing the quality of the included studies， a network meta-analysis was conducted using R 4.3.2 software. Descriptive comparisons of characteristic adverse events （AEs） for each intervention were performed， followed by sensitivity analyses using different effect models to evaluate the robustness of the results.RESULTS A total of 5 RCTs involving 6 intervention regimens were included. Regarding efficacy， compared with trastuzumab emtansine， chemotherapy alone， and lapatinib+paclitaxel， anbenitamab+chemotherapy significantly prolonged patients’ median overall survival （OS） and median progression-free survival （PFS） （ P ＜0.05）. Compared with ramucirumab+paclitaxel and trastuzumab emtansine， trastuzumab deruxtecan also significantly prolonged patients’ median OS and median PFS （ P ＜0.05）. The top two treatment regimens in terms of surface under the cumulative ranking curve （SUCRA） were both anbenitamab+chemotherapy and trastuzumab deruxtecan. In terms of safety， the SUCRA for the incidence of adverse events （AEs） of any grade （41.6%-57.1%） was generally similar across treatments. The SUCRA for the incidence of grade≥3 AEs and serious AEs was lowest for trastuzumab emtansine （19.3%） and chemotherapy alone （25.9%）， respectively. The SUCRA for treatment-related mortality was lowest for anbenitamab+chemotherapy （3.7%）， while the SUCRA for treatment discontinuation due to AEs was lowest for trastuzumab deruxtecan （4.3%）； for both， the SUCRA was highest for lapatinib+paclitaxel （78.3% and 85.6%， respectively）. Regarding characteristic AEs， the incidence of interstitial lung disease/pneumonitis was highest in the trastuzumab deruxtecan group （13.93%）， the incidence of diarrhea was highest in the lapatinib+paclitaxel group （77.10%）， and hypertension was primarily observed in the ramucirumab+paclitaxel group （23.85%）. The results of the sensitivity analysis were consistent with those of the main analysis.CONCLUSIONS For second-line treatment regimens of patients with HER2-positive advanced gastric cancer， both anbenitamab+chemotherapy and trastuzumab deruxtecan demonstrate a trend toward superior OS and PFS benefits； in terms of safety， the incidence rates of AEs of any grade are similar across the intervention groups， but the characteristic profiles of AEs differ significantly among the regimens， requiring close clinical monitoring and comprehensive management throughout treatment.

A method for simultaneous determination of 21 kinds of Aconitum alkaloids(ATS)in biological specimens and infused liquor using ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS)was developed.The biological samples were pretreated with methanol-acetonitrile(1∶2,V/V)for protein precipitation,while infused liquors were diluted 100-fold with acetonitrile,followed by centrifugation,and filtration by a 0.22-μm membrane.Chromatographic separation was carried out on an EC-C18 column using gradient elution with the mixture of 10 mmol/L ammonium acetate and 0.2%formic acid as mobile phase A and acetonitrile as mobile phase B.With this method,all the analytes were separated within 9.5 min.The samples were detected in positive ESI mode with dynamic multiple reaction monitoring(MRM)and quantified via external standard calibration.The results showed that the concentrations of the analytes in the range of 2-1000 ng/mL had excellent linearity(R2>0.9992)with the peak area.The developed method was successfully used for detection of 21 kinds of aconitum alkaloids,with limits of detection of 0.5-2 ng/mL,quantification limits of 2-6 ng/mL,intra/inter-day precision≤6.0%,spiked recoveries of 89.4%-100.9%,extraction recoveries of 74.2%-104.4%,and matrix effects ranging from-11.1%to 9.2%in blood/urine.The method was applied to detection of 12 samples from 4 fatal aconite poisoning cases,and all 21 kinds of ATS with total alkaloid concentrations of 0.04-4.18 μg/mL in blood and 154.96-422.83 μg/mL in medicinal liquors were detected.Tissue distribution revealed that the order of concentrations from highest to lowest is as follows:urine(157.22 μg/mL)>gastric contents(51.37 μg/mL)>kidney(21.6 μg/g)>whole blood(4.18 μg/mL)>liver(0.03 μg/g).This method showed many advantages such as simple pretreatment,low detection limits,accurate quantification,broad analyte coverage,and superior anti-interference capability in complex matrices,proving ideal for forensic and toxicological analysis of aconitum alkaloids.

Objective:To compare the efficacy and safety of irradiation-incorporated and chemotherapy only-based myeloablative conditioning regimens in haploidentical hematopoietic stem cell transplantation (haplo-HSCT) for patients with high-risk myeloid malignancies.Methods:This study retrospectively collected clinical data from 63 high-risk acute myeloid leukemia/myelodysplastic syndrome (AML/MDS) patients who underwent haplo-HSCT at the Fifth Medical Center of the Chinese PLA General Hospital from January 2015 to December 2019. These patients were classified into the irradiation ( n = 17) and chemotherapy ( n = 46) groups based on different conditioning regimens. The differences between the two groups were compared in terms of hematopoietic reconstitution, cumulative incidence of acute/chronic graft-versus-host diseases (aGVHD and cGVHD), non-relapse mortality (NRM), relapse rate (RR), overall survival (OS), and disease-free survival (DFS), followed by the analysis of prognostic factors. Results:The median follow-up time for the irradiation and chemotherapy groups was 78.5 and 72.3 months, respectively. The median time for neutrophil engraftment was 14.0 days in the irradiation group and 14.5 d in the chemotherapy group, and for platelet engraftment was 15.0 and 13.0 d, respectively. As a result, the two groups showed no statistically significant differences in hematopoietic reconstitution ( P > 0.05). The cumulative incidence of aGVHD and cGVHD was higher in the irradiation group compared to the chemotherapy group, yet showing no statistically significant differences ( P > 0.05). Specifically, the cumulative incidence of grade Ⅱ-Ⅳ aGVHD within 100 d was 29.4% and 21.7% for the irradiation and chemotherapy groups, respectively. The cumulative incidence of grade Ⅲ-Ⅳ aGVHD was 23.5% and 13.0%, respectively. The cumulative incidence of severe cGVHD within five years was 11.8% in the irradiation group and 8.7% in the chemotherapy group. In terms of long-term survival, the cumulative 5\|year RR and NRM were 20.2% and 28.4% in the irradiation group, 5.9% and 23.9% in the chemotherapy group, respectively, showing no statistically significant differences ( P > 0.05). The 5-year DFS and OS rates were 73.9% and 47.7% in the irradiation group, and 81.1% and 54.4% in the chemotherapy group, respectively, without statistically significant differences ( P > 0.05). Notably, the irradiation group manifested more favorable DFS and OS survival curves compared to the chemotherapy group. The survival curves indicate that the irradiation-incorporated regimen exhibited better trends in OS, DFS, and cGVHD-free relapse-free survival (GRFS). However, multivariate analysis did not reveal that irradiation conditioning is an independent prognostic factor affecting survival [ HR = 0.532 (0.163-1.735), 0.370 (0.091-1.516), 0.683 (0.248-1.882), P > 0.05]. Conclusions:In haplo-HSCT for high-risk myeloid malignancies, the irradiation-incorporated conditioning regimen demonstrates lower RR and NRM, higher DFS and OS, and potentially superior survival outcomes compared to the chemotherapy only-based regimen. Therefore, the irradiation-incorporated conditioning regimen may be preferentially considered in haplo-HSCT.

OBJECTIVE To evaluate the efficacy,safety and economics of the centrally procured generic versus original esomeprazole in the treatment of acute non-variceal upper gastrointestinal bleeding(ANVUGIB).METHODS A retrospective collection of real-world clinical data was conducted for ANVUGIB patients who received treatment at Shenzhen People's Hospital and University of Hong Kong-Shenzhen Hospital from January 2018 to March 2024.Patients were divided into imported original drug group(original drug group,221 cases)and centrally procured generic drug group(generic drug group,75 cases)according to the types of drug used.Propensity score matching(PSM)was performed at a ratio of 3∶1 to compare the clinical efficacy,safety and economics between the two groups.RESULTS Totally 241 patients were included after PSM,with 170 in the original drug group and 71 in the generic drug group.There were no significant differences between the two groups in terms of rebleeding rate,rate of second endoscopic intervention,blood transfusion rate,length of hospital stay,mortality due to gastrointestinal bleeding,30-day readmission due to rebleeding,and overall survival rate(P＞0.05).The incidence of adverse events among all patients in both groups also showed no statistically significant difference(P＞0.05);furthermore,the adverse events reported by the respective hospitals to the National Center for ADR Monitoring were comparable between the two groups.After PSM,the median total drug cost and high-dose esomeprazole cost in the generic drug group were significantly lower than those in the original drug group,while the median nursing fee and bed fee were significantly higher than those in the original drug group(P＜0.05).There was no statistically significant difference between the two groups in terms of median total hospitalization expenses,total treatment costs,laboratory fees,examination fees,material costs,or consultation fees(P＞0.05).CONCLUSIONS The clinical efficacy and safety of centrally procured generic esomeprazole in the treatment of ANVUGIB are comparable to those of the original drug,and it is more economical.
