Triptolide (TP), the core active component of the traditional Chinese medicine Tripterygium wilfordii , exhibits remarkable pharmacological activities including anti-inflammatory, immunosuppressive and anti-tumor effects, and holds broad application prospects in the treatment of major diseases such as autoimmune diseases and malignant tumors. However, TP has a narrow therapeutic window and causes multi-organ toxicities including liver, kidney and reproductive toxicities, which severely restrict its safe clinical application and new drug development. Therefore, toxicity reduction and efficacy enhancement has become a core scientific problem urgently to be solved in this field. This paper systematically reviews the four core strategies for TP toxicity reduction and efficacy enhancement, including structural modification, dosage form improvement, herbal compatibility, and external therapies of traditional Chinese medicine. Among them, structural modification optimizes the toxic and efficacy characteristics of TP from the molecular structure level, with typica l derivatives including (5 R )-5-hydroxy triptolide, ZT01, PG490-88, etc. Dosage form modification achieves toxicity reduction and efficacy enhancement via targeted and sustained-controlled drug release of diverse delivery systems. It includes triptolide preparations such as nanoparticles, liposomes, microemulsion gels and liquid crystals, possessing favorable clinical transformation potential. The herbal compatibility and external therapies of traditional Chinese medicine conform to the holistic view of traditional Chinese medicine and have a profound clinical application foundation, but their mechanisms of action are insufficiently elucidated, and they lack unified standardized specifications and high-quality evidence-based proof. In the future, we should rely on multi-omics technology to elucidate the toxic and efficacy mechanisms, integrate technologies to optimize preparations, improve the evaluation system and promote clinical transformation.

Background:
Adrenocortical hormones, particularly 11-oxygenated androgens, are pivotal in female reproductive health and fertility. Standardized detection kits and population-specific reference intervals are lacking in China, hindering related clinical applications.
Methods:
A HPLC-tandem mass spectrometry (HPLC-MS/MS) pipeline was developed, rigorously validated, and applied to simultaneously quantify corticosterone, cortisone, cortisol, 18-OH cortisol, androstenedione (A4), 11β-hydroxyandrostenedione (11-OH A4), dehydroepiandrosterone, and dehydroepiandrosterone sulfate in serum samples from 455 reproductive-aged women (18–45 yrs) in Guangxi, China. Age-dependent concentration trends were analyzed, and reference intervals stratified by age (2.5th to 97.5th percentiles) were established. Correlations with body-composition metrics, ethnicity, and the menstrual cycle were investigated.
Results:
The HPLC-MS/MS method demonstrated high precision (intra- and inter-assay CVs < 15%), accuracy, and sensitivity. All eight hormones exhibited significant age-related declines (P < 0.001 for seven hormones; P = 0.001 for 11-OH A4). Notably, 11-OH A4 levels were significantly lower in the 35–45-yr (3.05 nmol/L) and 25–34-yr (3.09 nmol/L) age groups than in the 18–24-yr (3.57 nmol/L) age group, whereas no significant difference was observed between the 35–45-yr and 25–34-yr age groups. Weak negative correlations were observed between the body mass index and corticosterone and cortisone levels, whereas ethnicity and the menstrual cycle showed no significant associations with hormone levels.
Conclusions
We developed an HPLC-MS/MS-based method for simultaneously quantifying eight adrenocortical hormones, including 11-OH A4, and defined age-specific reference intervals for reproductive-aged Chinese women. These findings advance the clinical utility of adrenocortical hormones in diagnosing and managing reproductive disorders.

Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease mediated by T lymphocytes, and it can progress to liver cirrhosis or even liver failure without timely intervention. As a natural flavonoid compound, naringenin (NAR) shows a potential value in the prevention and treatment of AIH through multiple mechanisms such as remodeling immune homeostasis, targeted inhibition of inflammatory pathways, antioxidation, regulating hepatocyte metabolism and apoptosis, improving mitochondrial function, and regulating intestinal flora. However, the clinical translation and application of NAR is limited by issues such as low bioavailability and insufficient efficiency of liver-targeted delivery. This article systematically reviews the mechanism of action of NAR in the prevention and treatment of AIH, explores the potential signaling pathways involved in this process, and analyzes existing challenges in its translation and application and future research directions, so as to provide a reference for further research on NAR and its application in the prevention and treatment of AIH.

The core pathogenesis of childhood IgA vasculitis nephritis (IgAVN) lies in the intermingled conditions of heat, stasis and deficiency. Deficiency is the fundamental cause, while heat acts as the predominant manifestation at the initial stage, and stasis serves as the key factor leading to protracted illness. Based on this understanding, the overall therapeutic principle of clearing heat and cooling blood, dissolving stasis and unblocking collaterals, reinforcing healthy qi and consolidating the root is established. A self-formulated Qingre Zhixue Formula (清热止血方) is used as the basic prescription. According to the characteristics of different disease stages, childhood IgAVN is further classified into three main syndrome types, including blood heat with stasis obstruction, deficiency of both qi and yin, and deficiency of both spleen and kidney, with corresponding syndrome-based treatments. Throughout the treatment process, emphasis is placed on dissolving stasis and unblocking collaterals, while protecting the spleen and stomach of children and maintaining healthy qi. This paper provides new perspectives for diagnosis and treatment of childhood IgAVN with traditional Chinese medicine.

To assess the current status of early surgical site infections following prosthetic implantation in plastic surgery across four provincial-level administrative regions in China, and to explore the effectiveness of standardized training for infection prevention and control. From January to May 2025, an online questionnaire survey was conducted to perform a baseline investigation in medical institutions performing plastic and aesthetic prosthetic implant surgeries in Chongqing, Shaanxi, Jiangxi, and Guizhou provinces. Data were collected on the volume of various types of prosthetic implant surgeries and the corresponding incidence of early surgical site infections. Improvement strategies for the prevention and control of early surgical site infections in prosthetic implant surgeries were jointly developed by the National Medical Quality Control Center for Plastic and Aesthetic Surgery and the National Medical Quality Control Center for Hospital Infection Management, followed by promotion and training. Subsequently, post-implementation data from June to October 2025 were collected from the above regions, and comparisons were made between pre- and post-implementation periods across different regions and surgical categories. A total of 209 medical institutions were included in the baseline period, with a questionnaire response rate of 99.52% and a total of 7475 prosthetic implantation surgeries. In the post-implementation period, 624 medical institutions were included, with a response rate of 96.00% and a total of 4813 surgeries. The combined proportion of breast prosthesis implantation and nasal/nasal base prosthesis implantation surgeries consistently exceeded 80% across all regions and periods. Regarding the distribution of infection cases, among different types of prosthetic implant surgeries, nasal/nasal base prostheses accounted for the highest proportion, with 57.50%(23/40) at baseline and 62.86% 22/35) post-implementation. The proportion of breast prosthesis infections decreased from 40.00%(16/40) at baseline to 17.14%(6/35) post-implementation. Across different regions, infection cases in Jiangxi (post-implementation)(100%), Guizhou[both baseline(100%) and post-implementation(100%)] were all concentrated in nasal/nasal base prostheses. Shaanxi reported four cases of chin prosthesis infections (22.22%) during the post-implementation period, and Chongqing reported three cases of metal-related infections(27.27%) during the post-implementation period. In terms of infection rates, Chongqing(0.55% Breast prostheses and nasal/nasal base prostheses currently represent the main types of implants used in prosthetic implantation surgeries. The improvement strategies implemented in this study were associated with decreased early surgical site infection rates in multiple regions, suggesting that these strategies provide clinical insights for the prevention and control of early infections following prosthetic implantation surgeries in China.

Objective:To investigate the perioperative safety, short-term and long-term efficacy, and surgical strategy of laparoscopic partial gastrectomy for gastrointestinal stromal tumors at the esophagogastric junction.Methods:Seventy-eight patients with mesenchymal tumors in the esophagogastric junction were retrospectively enrolled from September 2018 to August 2023 in which the upper edge of the tumor is less than 2 cm from the Z-line or has invaded the Z-line <1/2 circumference. There were 31 males (39.7%) and 47 females (60.3%), with an average age of (57.2±11.8) years and an average body mass index of (24.5±3.5) kg/m 2. All cases were divided into the wedge resection (WR) group ( n=51) and the resection by opening all of the layers of the stomach wall (RASW) group ( n=27) according to the surgical methods. Surgical outcomes, complications, recover and postoperative gastroesophageal reflux of both groups were compared. The measurement data with a normal distribution were represented by mean±standard deviation ( ± s), and values were compared using the independent sample t-test. The measurement data with a skewed distribution were represented by median (interquartile range) [ M( Q1, Q3)], and values were compared using the Mann-Whitney U test. Count data were expressed as examples (percentages) [ n(%)], and the χ2 test was used to compare countable data. A non-parametric test was used to compare the grade data. Results:The WR group had shorter operation time [(97.1±32.6) min vs (149.9±54.9) min, t=-5.33, P<0.001], less intraoperative blood loss [15(10, 20) mL vs 20(10, 50) mL, z=-2.47, P=0.014], shorter postoperative exhaust time [2(1, 3) d vs 3(2, 3) d, z=-2.49, P=0.013], shorter postoperative oral intake time [2(2, 3) d vs 4(2, 5) d, t=-3.70, P<0.001], shorter postoperative semi-liquid diet time[5(4, 6) d vs 7(5, 8) d, z=-3.57, P<0.001], and shorter postoperative hospital stay [5(4, 6) d vs 7(6, 8) d, z=-4.16, P<0.001] than the RASW group, with statistically significant differences. There was no significant difference in short-term (≤30 days) complications between the two groups (2.0% vs 3.7%, z=-0.46, P=0.648). No cases of cardia stenosis occurred in either group. In the WR group, 3 patients developed gastroesophageal reflux at 6 months postoperatively, with 2 patients relieved after taking acid-suppressing drugs and 1 patient not completely relieved. In the RASW group, 1 patient developed gastroesophageal reflux at 6 months postoperatively and was not completely relieved after taking acid-suppressing drugs. No other patients had gastroesophageal reflux. No other patients have gastroesophageal reflux. Conclusions:WR and RASW are safe and feasible for mesenchymal tumors at the esophagogastric junction in which the upper edge of the tumor is less than 2 cm from the Z-line or has invaded the Z-line <1/2 circumference, and has achieved an excellent short-term effect. The choice of surgical approach can be determined based on varions factors such as the location of the tumor, the relationship of the position between the tumor and the cardia, and whether the tumor is exophytic growth.
