In recent years， with the extensive application of traditional Chinese medicine （TCM） both domestically and internationally， safety concerns associated with TCM have been frequently reported. Notably， some TCM substances traditionally regarded as ''non-toxic'' have exhibited significant adverse reactions during clinical use， drawing substantial attention to TCM safety. This study first analyzed the risk factors contributing to the potential toxicity of TCM from perspectives such as drug properties， individual constitution， and clinical medication practices. Subsequently， it proposed research strategies and methodologies for investigating potential TCM toxicity： ① conduct studies under the guidance of TCM theory， adhering to the principle of diversity and unity. ② adopt an integrated research paradigm of ''originating from clinical practice-syndrome-based foundation-returning to clinical practice-serving supervision''. ③ implement a three-tier technical system of ''Mathematical modeling-high-throughput screening via liquid chromatography-mass spectrometry （LC-MS）-systems biology'' to systematically elucidate the causes， material basis， and mechanisms of toxicity. Finally， scientific regulatory recommendations for potential TCM toxicity are proposed： ① establish a multidimensional prevention and control system addressing drug properties， physical constitution factors， and clinical medication practices. ② address the impact of modern processing techniques on the safety of new TCM drugs. ③ strengthen the revision of standards for Chinese medicinal materials to ensure their safety. ④ account for disease-syndrome combination animal models and interspecies differences in safety assessment outcomes. This study aims to overcome critical challenges in TCM regulation by advancing evaluation through research and driving research through evaluation. By establishing a high-level scientific regulatory framework， it seeks to not only safeguard clinical medication safety but also propel the high-quality development of the TCM industry， thereby providing scientific support for the inheritance and innovative evolution of TCM.

ObjectiveTo explore the effects of astragalin （AST） on autophagy and apoptosis of astrocytes in the L_4-5 dorsal horn of the spinal cord in mice with inflammatory pain induced by complete Freund's adjuvant （CFA）. MethodsTwenty-four male C57BL/6 mice， aged six months， were randomly assigned to four groups： control group， saline group， CFA model group， and CFA+AST group， six mice in each group. The inflammatory pain model was established by injection of 10 µL CFA into the right lateral malleolus fossa. The saline group were injected with an equal amount of normal saline at the same site. The inflammatory pain mice in CFA+AST group were further treated with AST （60 mg/kg） intraperitoneally once a day for 21 consecutive days. Multiplex immunofluorescence staining was used to detect the coexpression of autophagy-related factors including ATG 12 and Beclin-1， apoptosis-related factors including Cleaved-Caspase3 and Caspase9， and the astrocyte marker such as GFAP in the L_4-5 spinal dorsal horn of the mice in each group. Western blot was used to examine the protein expression levels of autophagy-related proteins（ATG12， Beclin-1） and apoptosis-related proteins（Caspase 3， Caspase 9） in the L_4-5 spinal dorsal horn of mice. ResultsImmunofluorescent staining showed that in the L_4-5 dorsal horn of the spinal cord， the fluorescence intensity of ATG12 （P<0.000 1） and Beclin-1 （P<0.000 1） was significantly increased， while that of Cleaved-Caspase 3 （P<0.001） and Caspase 9 （P<0.000 1） was decreased in the CFA+AST group when compared to the CFA model group. Furthermore， AST could inhibit the activation of astrocytes. Western blot further confirmed that AST significantly upregulated the expression of ATG12 （P<0.000 1） and Beclin-1 （P<0.000 1） in the L_4-5 spinal cord of CFA mice， and downregulated the expression of Caspase 3 （P<0.01） and Caspase 9 （P<0.001）. ConclusionsAST promotes autophagy of astrocytes and inhibits their apoptosis in the L_4-5 spinal dorsal horn of CFA mice.

OBJECTIVES: To evaluate the effectiveness of single-balloon and double-balloon enteroscopy in diagnosing pediatric small bowel diseases and assess the diagnostic efficacy of computed tomography enterography (CTE) for small bowel diseases using enteroscopy as the reference standard. METHODS: Clinical data from 576 children who underwent enteroscopy at Hunan Children's Hospital between January 2017 and December 2023 were retrospectively collected. The children were categorized based on enteroscopy type into the single-balloon enteroscopy (SBE) group (n=457) and double-balloon enteroscopy (DBE) group (n=119), and the clinical data were compared between the two groups. The sensitivity and specificity of CTE for diagnosing small bowel diseases were evaluated using enteroscopy results as the standard. RESULTS: Among the 576 children, small bowel lesions were detected by enteroscopy in 274 children (47.6%).There was no significant difference in lesion detection rates or complication rates between the SBE and DBE groups (P>0.05), but the DBE group had deeper insertion, longer procedure time, and higher complete small bowel examination rate (P<0.05). The complication rate during enteroscopy was 4.3% (25/576), with 18 cases (3.1%) of mild complications and 7 cases (1.2%) of severe complications, which improved with symptomatic treatment, surgical, or endoscopic intervention. Among the 412 children who underwent CTE, the sensitivity and specificity for diagnosing small bowel diseases were 44.4% and 71.3%, respectively. CONCLUSIONS SBE and DBE have similar diagnostic efficacy for pediatric small bowel diseases, but DBE is preferred for suspected deep small bowel lesions and comprehensive small bowel examination. Enteroscopy in children demonstrates relatively good overall safety. CTE demonstrates relatively low sensitivity but comparatively high specificity for diagnosing small bowel diseases.

Traditional Chinese medicine (TCM) is a well-accepted therapy for atopic dermatitis (AD). However, there are currently no evidence-based guidelines integrating TCM and Western medicine for the treatment of AD, limiting the clinical application of such combined approaches. Therefore, the China Association of Chinese Medicine initiated the development of the current guideline, focusing on key issues related to the use of TCM in the treatment of AD. This guideline was developed in accordance with the principles of the guideline formulation manual published by the World Health Organization. A comprehensive review of the literature on the combined use of TCM and Western medicine to treat AD was conducted. The findings were extensively discussed by experts in dermatology and pharmacy with expertise in both TCM and Western medicine. This guideline comprises 23 recommendations across seven major areas, including TCM syndrome differentiation and classification of AD, principles and application scenarios of TCM combined with Western medicine for treating AD, outcome indicators for evaluating clinical efficacy of AD treatment, integration of TCM pattern classification and Western medicine across disease stages, daily management of AD, the use of internal TCM therapies and proprietary Chinese medicines, and TCM external treatments.

Compared with matrix-assisted laser desorption ionization mass spectrometry(MALDI-MS)using organic small molecule matrix,surface-assisted laser desorption ionization mass spectrometry(SALDI-MS)based on nanomaterial matrix is more effective in analysis of small molecule compounds.Ion sputtering instruments have obvious advantages for applying inorganic nanomatrix.In this work,the carbon-platinum material was sputtered onto a glass cover slip using an ion sputtering instrument to form a carbon-platinum(C-Pt)composite nanomatrix,and an SALDI-MS analytical method was thus established based on the prefabricated C-Pt composite matrix.The experimental results showed that the C-Pt composite nanomatrix could significantly improve the signal intensity and signal-to-noise ratio of the mass spectrum peaks of the components to be measured.The ratio of carbon to platinum,the duration of ion sputtering,and the laser power in mass spectrometer were investigated to select the optimal C-Pt matrix prefabricated conditions and SALDI-MS experimental conditions.Using the prefabricated C-Pt composite matrix,the melittriose and daidzein sample solution were applied as sample to examine repeatability.The results showed that the intra-point repeatability(RSD)was≤4.8%and the inter-point repeatability(RSD)was≤6.4%.The quercetin and melitriose were applied as model samples,and a linearity between MS peak intensity and respective concentration in the range of 0.05-1.0 mg/mL was found,with linear correlation coefficients(R2)greater than 0.994,showing good potential for quantitative and imaging analysis.Then,the prefabricated C-Pt composite matrix was applied to SALDI-MS analysis of the 50%ethanol extract of soybean,and 15 kinds of compounds including oligosaccharides and triglycerides were identified from the mass spectra.Furthermore,the C-Pt matrix was employed in SALDI-MS imaging for the compositions in corn tissue section,and the results showed that diglycerides and triglycerides were mainly distributed in the corn embryo and around the embryo,and the distribution of oligosaccharides was relatively even.

ObjectiveHuman Ku70 protein mainly involves the non-homologous end joining (NHEJ) repair of double-stranded DNA breaks (DSB) through its DNA-binding properties, and it is recently reported having an RNA-binding ability. This paper is to explore whether Ku70 has RNA helicase activity and affects miRNA maturation. MethodsRNAs bound to Ku protein were analyzed by RNA immunoprecipitation sequencing (RIP-seq) and bioinfomatic anaylsis. The expression relationship between Ku protein and miRNAs was verified by Western blot (WB) and quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) assays. Binding ability of Ku protein to the RNAs was tested by biolayer interferometry (BLI) assay. RNA helicase activity of Ku protein was identified with EMSA assay. The effect of Ku70 regulated miR-124 on neuronal differentiation was performed by morphology analysis, WB and immunofluorescence assays with or without Zika virus (ZIKV) infection. ResultsWe revealed that the Ku70 protein had RNA helicase activity and affected miRNA maturation. Deficiency of Ku70 led to the up-regulation of a large number of mature miRNAs, especially neuronal specific miRNAs like miR-124. The knockdown of Ku70 promoted neuronal differentiation in human neural progenitor cells (hNPCs) and SH-SY5Y cells by boosting miR-124 maturation. Importantly, ZIKV infection reduced the expression of Ku70 whereas increased expression of miR-124 in hNPCs, and led to morphologically neuronal differentiation. ConclusionOur study revealed a novel function of Ku70 as an RNA helicase and regulating miRNA maturation. The reduced expression of Ku70 with ZIKV infection increased the expression of miR-124 and led to the premature differentiation of embryonic neural progenitor cells, which might be one of the causes of microcephaly.

Objective:To establish a practical and systematic pre-deployment base-based training course for medical units in peacekeeping level-II hospitals.Methods:We surveyed the current status of pre-deployment training of medical teams in peacekeeping level-II hospitals, and organized expert discussions to preliminarily construct centralized training course contents. At the same time, the Delphi method was used to conduct two rounds of questionnaire-based consultation to evaluate the overall framework design of the course and the rationality and importance scores of each module. The contents of the pre-deployment training course were further selected and optimized based on the positive coefficient (%), authority coefficient (Cr), coefficient of concordance ( W), and coefficient of variation (Cv). Results:The contents of the pre-deployment training course for the medical units of peacekeeping level-II hospitals were preliminarily established. The experts scored high for the combat onsite first-aid skills module [rationality score, (9.32±0.75) points; importance score, (9.45±0.65) points] and the combat wound treatment module [rationality score, (9.33±0.75) points; importance score, (9.28±0.74) points], and scored lowest for the field survival module [rationality score, (7.95±2.28) points; importance score, (7.87±2.16) points].Conclusions:The established contents of the pre-deployment base-based training course for the medical units of peacekeeping level-II hospitals are reasonable and practical, which lays the foundation for perfecting the pre-deployment training system of peacekeeping medical teams.
