ObjectiveTo summarize the incidence and clinical features of drug hypersensitivity reactions in children treated with sustained-releasing gonadotropin-releasing hormone agonists （GnRHa）， aiming to provide guidance for the safe clinical application of GnRHa in children. MethodsThe medical data of children diagnosed with central precocious puberty （CPP） or early and fast puberty （EFP） were retrospectively analyzed， who received GnRHa treatment at the Children's Growth Center of the First Affiliated Hospital of Sun Yat-sen University between January 1990 and July 2023. The occurrence of GnRHa-related drug hypersensitivity reactions were summarized， including the incidence and clinical features of systemic reactions and sterile abscesses. ResultsAmong the 1 684 children treated with GnRHa for CPP/EFP， the female-to-male ratio was 3.8∶1. A total of nine children （0.53%） developed 44 occurrences of drug hypersensitivity reactions. Four children （0.24%） presented with sterile abscesses （21 occurrences）， and five children （0.30%） experienced systemic hypersensitivity reactions （14 occurrences）. Four children were hypersensitive to triptorelin acetate， three were hypersensitive to leuprorelin acetate， and two were hypersensitive to both triptorelin acetate and leuprorelin acetate. The predominant hypersensitivity reactions to leuprorelin acetate were sterile abscesses， observed in four cases （4/277， 1.44%）， whereas the main reactions to triptorelin acetate were systemic hypersensitivity reactions， affecting five cases （5/1 501， 0.33%）. Case one presented with a severe and complex condition， exhibiting hypersensitivity to multiple GnRHa preparations （sustained-releasing triptorelin， sustained-releasing leuprorelin， and short-acting triptorelin）， and presenting with diverse manifestations， including induration， sterile abscesses， systemic hypersensitivity reactions， and even loss of suppression of the hypothalamic-pituitary-gonadal axis， leading to treatment failure. ConclusionsThe proportion of children experiencing drug hypersensitivity reactions to sustained-releasing GnRHa is relatively low at 0.53%， with diverse manifestations. The reactions primarily manifest as sterile abscesses and systemic hypersensitivity reactions， and in severe cases， may lead to treatment failure due to loss of suppression of the hypothalamic-pituitary-gonadal axis.

To address the challenges of fragmented data, inconsistent standards, and delayed feedback in the full-cycle competency development process at teaching hospitals, this paper proposes the LEADS data governance system for Precision Medical Education (LEADS-PME), drawing on the practical experience of building the integrated medical education management platform at Zhongshan Hospital, Fudan University. The LEADS-PME framework comprises five interconnected core components: Longitudinal foundation, Evidence-chain generation, Analytics and profiling, Decision-support and prediction, and Simulation and digital-twin governance. Currently, Zhongshan Hospital has established a full-cycle educational data infrastructure and achieved multi-system data integration and competency-based profiling and evaluation, while the prediction and simulation modules are still in the prototype exploration phase. A mixed-methods evaluation will be subsequently conducted from the perspectives of data quality, management effectiveness, and predictive intervention. As a locally adapted framework, LEADS-PME can transform operational data derived from clinical practice, teaching, assessment, and management processes into traceable, interpretable, and reusable evidence of competency development. It is expected to facilitate the transformation of medical education management from a outcome-oriented approach to process monitoring, evidence-driven decision-making, and precision governance, thereby providing both a theoretical framework and practical reference for precision medical education in Chinese teaching hospitals.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

Helicobacter pylori(H.pylori)infection triggers gastric mucosal inflammatory responses and spasmolytic polypeptide-expressing metaplasia(SPEM).These pathological conditions can escalate the severity of chronic gas-tritis,gastric ulcers and even cause gastric cancer.SPEM is frequently viewed as an early sign of gastric mucosal injury and the onset of carcinogenesis.A comprehensive analysis of the genesis and molecular regulation of SPEM cells in the context of H.pylori infection further has enlightened the pathogenesis of gastric mucosal diseases and provide new ideas and targets for diagnosing and treatment of H.pylori-related gastric mucosal diseases.This paper reviews a variety of molecular biomarkers associated with SPEM,encompassing TFF2,CD44v9,and AQP5,and delineates their pivotal regulatory functions in H.pylori infection and SPEM.This paper also reviews the origination of SPEM cells and pertinent molecular regulatory mechanisms.

ObjectiveTo investigate the therapeutic effect of sequential administration of Dihuang Baoyuan granules （DHBY， the prescription for consolidating body resistance） and Fuling Yunhua granules （FLYH， the prescription for treating symptoms） on spontaneous type 2 diabetes mellitus （T2DM） in mice. MethodsAccording to the fasting blood glucose （FBG） level， 12-week-old db/db mice were randomized into six groups： model， DHBY （18.02 g·kg^-1）， FLYH （14.80 g·kg^-1）， sequential administration 1 （SEQ-1， DHBY 18.02 g·kg^-1+FLYH 14.80 g·kg^-1）， sequential administration 2 （SEQ-2， FLYH 14.80 g·kg^-1+DHBY 18.02 g·kg^-1）， and dapagliflozin （Dapa， 1.3 mg·kg^-1）. The m/m mice in the same litter were selected as the normal group. The mice were administrated with corresponding drugs by gavage for 8 consecutive weeks. During the 8 weeks of drug administration and 2 weeks after withdrawal， the retinal thickness， FBG， hemoglobin A1c （HbA1c）， and insulin were determined， and histopathological changes of the pancreas， liver， kidney， and retina were observed by hematoxylin-eosin （HE） staining. ResultsCompared with the model group， SEQ-1 for 4 weeks lowered the FBG level （P<0.05）， raised the insulin level， decreased the triglyceride （TG） level （P<0.05）， increased the number of optic ganglion cells and diminished vacuolar degeneration of pancreatic islet and liver. SEQ-2 lowered FBG and HbA1c levels （P<0.05）， rose the insulin level， increased the retinal thickness and the number of optic ganglion cells （P<0.05）， and alleviated vacuolar degeneration of pancreatic islet and liver. Two weeks after drug withdrawal， Dapa tended to increase FBG and HbA1c compared with those at the time of drug withdrawal. However， the levels of FBG and HbA1c in the SEQ-2 group remained decreasing （P<0.05）. ConclusionSEQ-1 and SEQ-2 can lower the blood glucose level and ameliorate diabetic retinopathy， and SEQ-2 outperformed DHBY and FLYH in lowering the blood glucose level. Moreover， SEQ-2 can maintain the blood glucose-lowering effect after drug withdrawal.

Objective:To analyze the clinical characteristics and gene mutations of 4 patients with the male phenotype of 17α-hydroxylase /17, 20-lyase deficiency(17-OHD), in order to improve the recognition and appropriate management of atypical cases.Methods:A retrospective analysis was performed on the clinical features, biochemical findings, and gene mutations of 4 patients with the male phenotype of 17-OHD treated in our hospital between 2018 and 2023.Results:The social gender of all 4 patients with 17-OHD was male. None of the 4 patients had hypertension or hypokalemia, but all had micropenis and gynecomastia. Two patients had adrenal hyperplasia, while adrenal morphology was normal in the other two. One patient had decreased bone mass. There were typical changes in the steroid synthesis-related hormone spectrum: progesterone was significantly elevated in all 4 patients, 17-hydroxyprogesterone was not markedly abnormal, cortisol, dehydroepiandrosterone sulfate(DHEAS) and estradiol levels were low, and testosterone levels were also low.Conclusion:17-OHD is a rare type of congenital adrenal hyperplasia, with the male phenotype being even rarer. Early symptoms are often atypical, resulting in high rates of misdiagnosis and missed diagnosis. Patients without hypertension and hypokalemia are particularly prone to diagnostic confusion. Male patients with unexplained progesterone elevation, poor secondary sexual development, and gynecomastia should undergo timely steroid hormone profiling and genetic testing to avoid misdiagnosis and missed diagnosis.

Objective:To investigate the current status of standardized residency training (SRT) teaching activities at Zhongshan Hospital affiliated to Fudan University, and to explore optimization strategies.Methods:We collected behavioral data from the SRT course selection platform and resident questionnaire survey data throughout 2024. Descriptive analysis, chi-square test, Mann-Whitney U test, and multivariable logistic regression analysis were performed. Results:A total of 170 teaching sessions were conducted in 2024, with interactive practice-based sessions accounting for 42.35% and lecture-based sessions accounting for 47.06%. According to 536 questionnaires, residents' overall satisfaction with teaching activities scored 87.83 points (high satisfaction, ≥85 points; moderate satisfaction, <85 points). The proportion of high satisfaction with interactive practice-based sessions was significantly higher than that with lecture-based sessions (82.81% vs. 75.46%, P=0.034). The enrollment for weekday evening courses filled up significantly faster than that for weekday daytime courses [4 (2, 6) seconds vs. 12 (8, 15) seconds, P<0.001]. Interactive practice-based sessions [odds ratio ( OR)=1.6, 95% CI=1.1-2.3, P=0.018] and weekday evening sessions ( OR=1.4, 95% CI=1.0-2.0, P=0.048) significantly improved resident satisfaction. Conclusions:Optimizing course formats and scheduling can enhance the quality of SRT teaching activities.

Objective:To explore the application effect of multidisciplinary graded nutritional intervention in patients with cervical cancer undergoing radiochemotherapy.Methods:A convenience sampling method was used to select 160 patients with cervical cancer who received radiochemotherapy in the First Affiliated Hospital of Wenzhou Medical University from June 2022 to June 2024. According to the order of admission, 80 patients admitted between June 2022 and June 2023 were assigned to the control group, and 80 patients admitted between July 2023 and June 2024 were assigned to the observation group. The control group received routine nutritional intervention, while the observation group received multidisciplinary graded nutritional intervention. Serum albumin, prealbumin, hemoglobin, body mass index (BMI), and Functional Assessment of Cancer Therapy-General (FACT-G) scores were compared between the two groups before and after intervention.Results:Before the intervention, there were no statistically significant differences between the two groups in serum albumin, prealbumin, hemoglobin, BMI, and FACT-G dimension scores ( P>0.05). After the intervention, serum albumin, prealbumin, hemoglobin, BMI, and FACT-G dimension scores were all higher in the observation group than in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Multidisciplinary graded nutritional intervention can improve the nutritional status and quality of life of patients with cervical cancer undergoing radiochemotherapy, and is worthy of wider application.
