To thoroughly implement the strategic deployment outlined in the Opinions of the Central Committee of the Communist Party of China and the State Council on Promoting the Inheritance and Innovative Development of Traditional Chinese Medicine regarding research on dominant diseases of traditional Chinese medicine and to uphold the development philosophy of equal emphasis on traditional Chinese medicine and western medicine，the China Association of Chinese Medicine has fully played a leading academic role by systematically organizing and conducting a series of academic youth salons on clinical dominant diseases of traditional Chinese medicine. On September 13，2024，the 36^th Youth Salon on Clinical Dominant Diseases was successfully held in Nanjing，focusing on the advantages of traditional Chinese medicine and the integrative traditional Chinese medicine and western medicine in the diagnosis and treatment of erectile dysfunction （ED）. The conference brought together leading experts from traditional Chinese medicine，western medicine，and interdisciplinary fields，facilitating in-depth multidisciplinary discussions that led to key consensus on optimizing traditional Chinese medicine treatment protocols for ED，researching and developing new drugs of traditional Chinese medicine，and advancing interdisciplinary development in traditional Chinese medicine. This salon systematically sorted out the clinical strengths and distinctive features of traditional Chinese medicine in the diagnosis and treatment of ED. Based on current research foundations and clinical needs，it identified key directions for future scientific layout and scientific research tackling： （1） Standardization of syndrome differentiation system of traditional Chinese medicine for ED. （2） Optimization and standardization of intervention methods of integrated traditional Chinese medicine and western medicine. （3） High-quality clinical research guided by evidence-based medicine. （4） In-depth analysis of the pharmacological mechanisms of traditional Chinese medicine in the treatment of ED. （5） Clinical translation and application promotion of new drugs of traditional Chinese medicine. （6） Interdisciplinary integration and innovation in traditional Chinese medicine. For each research direction，key focus areas，expected objectives，and clinical value were further refined，along with the establishment of a scientifically sound priority funding level evaluation system. Therefore，building on the series of salons on the ED-focused dominant diseases of traditional Chinese medicine，this paper provides standardized guidance for clinical practice of traditional Chinese medicine in ED management，effectively contributing to the high-quality development of traditional Chinese medicine. It serves as a valuable reference for national scientific and technological strategic layout， research and development decision-making in new drugs of traditional Chinese medicine，research topic planning，and clinical guideline formulation.

Langerhans cell histiocytosis（LCH）is an inflammatory myeloid neoplasm characterized by aberrant differentiation or proliferation of mononuclear phagocytes. Orbital involvement，termed orbital LCH（OLCH），typically presents with periorbital masses，eyelid edema，and localized osteolytic lesions. Besides，optic nerve involvement may cause diplopia，visual impairment and so on，significantly impairing quality of life. Central nervous system-Langerhans cell histiocytosis（CNS-LCH），including central diabetes insipidus and neurodegeneration，may cause irreversible sequelae such as diabetes insipidus，progressive tremor，and ataxia，severely impacting prognosis. Current management of OLCH and its association with CNS-LCH remain controversial.The Histiocyte Society considers OLCH to be one of the risk factors for CNS-LCH，and therefore should receive 6 months of systemic chemotherapy to prevent sequelae. However，conflicting evidence suggests an unclear relationship between OLCH and CNS-LCH progression，with studies demonstrating favorable outcomes in isolated orbital cases treated through localized approaches（surgical excision，curettage，or intralesional corticosteroid injection）.Patients with unifocal OLCH exhibit favorable prognosis and potential for spontaneous resolution，and may could spare from systemic chemotherapy to avoid related adverse effects.

Objective:To explore the differences on contraindication information for children in domestic and foreign drug instructions, and provide reference for improving the relevant information in Chinese drug insert sheets.Methods:Chinese drug insert sheets of chemicals and biological products contained in the China Pharmacopoeia 2020 and those of the western medicines in the 2023 China′s Basic Medical Insurance, Work-related Injury Insurance and Childbirth Insurance Drug Catalog were collected; drugs that were marked as contraindication for children were selected and relevant contraindication information in the Chinese drug insert sheets was collected. Instructions of the above-mentioned drugs approved by the U.S. Food and Drug Administration (English labels) were also collected, and the information on pediatric medication was reviewed and compared with the Chinese drug insert sheets. Results:A total of 222 drugs were labeled as contraindication for children in the Chinese drug insert sheets, of which 149 were available for their English labels; 123 drugs (17.5%) were not labeled as contraindication for children in English labels, and 26 (82.5%) were labeled. The 123 drugs that were not labeled as contraindication for children in the English labels included the following conditions: 58 were labeled as contraindication for children of some age in the Chinese drug insert sheets but not in the English labels, and relevant medication information was provided; 40 were labeled as contraindication for children of some age group in the Chinese drug insert sheets but was described as the effectiveness and safety of the use for children have not yet been determined for this age group in the English labels; 13 were labeled as contraindication for children in the Chinese drug insert sheets, but the medication information on children in the English labels was not clear or missing; 12 were labeled as contraindicated for children in Chinese drug insert sheets but not in the English labels, only expressed as not yet determined or not recommended for use, etc., with inconsistent age group. Among the 26 drugs labeled as contraindication for children in both Chinese and English instructions, the contraindication age group were the same in above 2 instructions for 20 drugs, and were inconsistent for the other 6 drugs; reasons for contraindication were described in both the 2 instructions for 17 drugs (13 were consistent, 4 were inconsistent), only in English labels for 8 drugs, and only in Chinese drug insert sheets for 1 drug.Conclusions:Many drugs are labeled as contraindication for children in Chinese drug insert sheets, but reasons for contraindication are rarely explained. Differences in children′s age in contraindications exist for some drugs between the Chinese drug insert sheets and English labels. The information on contraindications for children in Chinese drug insert sheets still needs to be further improved.

BACKGROUND:The study of deer antler stem cells and exosomes to promote the repair of acute skin injuries has received increasing attention in recent years,but the effect and mechanism of exosomes composite hydrogel to promote the repair of burn wounds are still unclear.OBJECTIVE:To investigate the effect of deer antler stem cell exosome composite hydrogel on the healing speed and quality of rat deep third-degree burn wound and its mechanism of action.METHODS:Deer antler stem cell exosomes and bone marrow mesenchymal stem cell exosomes were extracted and compounded with Pluronic F-127 to prepare a temperature-sensitive hydrogel.A constant temperature and pressure burn apparatus was used to prepare a rat model of deep third-degree burn.The drug was administered to four groups:deer antler stem cell exosome composite hydrogel group,bone marrow mesenchymal stem cell exosome composite hydrogel group,human epidermal growth factor gel group,and the control group.The healing of burned rats was observed and the wound healing rate was calculated.At 28 days after burn,hematoxylin-eosin staining was used to observe the generation of skin accessory structures in the healing tissues.Masson staining was used to analyze the accumulation of collagen in the healing tissues.Immunohistochemistry was used to examine the angiogenesis and nflammatory response in the healing tissues.qRT-PCR was used to examine the expression level of mRNA of the wound healing-related genes in the healing tissues.RESULTS AND CONCLUSION:(1)Deer antler stem cell exosome composite hydrogel can significantly promote the healing rate of deep burn wounds in rats,and improve the quality of wound healing by promoting the regeneration of skin collateral structures,increasing the dermal thickness and enhancing the accumulation of collagen.(2)The number of myofibroblasts in the wound healing tissues of deer antler stem cell exosome composite hydrogel group was significantly reduced,and the number of neovascularization and M2 macrophages was significantly increased.(3)The mRNA levels of transforming growth factor β3 and type Ⅲ collagen in the wound healing tissue of deer antler stem cell exosome composite hydrogel group were significantly higher than those of the blank group,and the mRNA levels of transforming growth factor β1,matrix metalloproteinase 3,and type Ⅰ collagen were significantly lower than those of the blank group,and there was no significant difference between the bone marrow-derived mesenchymal stem cell exosome composite hydrogel group and the human epidermal growth factor gel group.In conclusion,deer antler stem cell exosome composite hydrogel can promote the healing speed and the quality of healing of deep burned wounds in rats,which may be achieved by inhibiting fibroblastogenesis,promoting angiogenesis,macrophage M2 polarization,and regulating the expression of genes for collagen production/degradation.

Objective In order to provide a better reference and basis for the selection of reasonable hypoglycemic drugs for clinical treatment,the study conducted a comprehensive clinical evaluation of the innovator sodium-glucose transporters 2(SGLT-2)inhibitors,based on A Quick Guideline for Drug Evaluation and Selection in Chinese Medical Institutions(the Second Edition).Methods The real-world studies,randomized controlled trials,Meta-analysis/systematic review,drug clinical use guidelines,expert consensus and drug description evaluation evidence were collected,and the included drugs were assigned and evaluated from five dimensions:pharmaceutical characteristics,efficacy,safety,economy and other attributes.Results All SGLT-2 inhibitors had evaluation scores above 75,with dagaglifloztin tablets having the highest score of 84.6,and canaglifloztin having the lowest score of 75.1.Conclusions All five original SGLT-2 inhibitors showed good clinical utility,the difference is that the participating original drugs have different advantageous intervals in clinical use.The results show that dagliflozin has the most ideal clinical utility,and its clinical use should be safer and more effective.Due to the short time on the market and insufficient evidence-based reasons,the advantages of clinical use of proline hemegliflozin are not obvious compared with other evaluated drugs.

BACKGROUND: Arsenic trioxide (ATO) is indicated as a broad-spectrum medicine for a variety of diseases, including cancer and cardiac disease. While the role of ATO in hepatic ischemia/reperfusion injury (HIRI) has not been reported. Thus, the purpose of this study was to identify the effects of ATO on HIRI. METHODS: In the present study, we established a 70% hepatic warm I/R injury and partial hepatectomy (30% resection) animal models in vivo and hepatocytes anoxia/reoxygenation (A/R) models in vitro with ATO pretreatment and further assessed liver function by histopathologic changes, enzyme-linked immunosorbent assay, cell counting kit-8, and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay. Small interfering RNA (siRNA) for extracellular signal-regulated kinase (ERK) 1/2 was transfected to evaluate the role of ERK1/2 pathway during HIRI, followed by ATO pretreatment. The dynamic process of autophagic flux and numbers of autophagosomes were detected by green fluorescent protein-monomeric red fluorescent protein-LC3 (GFP-mRFP-LC3) staining and transmission electron microscopy. RESULTS: A low dose of ATO (0.75 μmol/L in vitro and 1 mg/kg in vivo ) significantly reduced tissue necrosis, inflammatory infiltration, and hepatocyte apoptosis during the process of hepatic I/R. Meanwhile, ATO obviously promoted the ability of cell proliferation and liver regeneration. Mechanistically, in vitro  studies have shown that nontoxic concentrations of ATO can activate both ERK and phosphoinositide 3-kinase-serine/threonine kinase (PI3K-AKT) pathways and further induce autophagy. The hepatoprotective mechanism of ATO, at least in part, relies on the effects of ATO on the activation of autophagy, which is ERK-dependent. CONCLUSION Low, non-toxic doses of ATO can activate ERK/PI3K-AKT pathways and induce ERK-dependent autophagy in hepatocytes, protecting liver against I/R injury and accelerating hepatocyte regeneration after partial hepatectomy.
