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.

Objective To analyze the difference of psoas major muscle morphology and pain degree in patients with different types of lumbar disc herniation ( LDH ) by quantitative CT, and to further explore the relationship between psoas major muscle morphology and pain degree. Methods A total of 120 patients with LDH admitted to our hospital from January to December 2025 were enrolled as study subjects. Based on clinical symptoms and lesion location, they were divided into a simple lower extremity pain group and a lumbar and leg pain group. All patients underwent lumbar CT examination. The psoas major muscle index was used as a CT quantitative parameter, which was calculated as the mean of the maximum cross-sectional areas of both psoas major muscles divided by the cross-sectional area of the L5 vertebral body. This index was measured to reflect psoas major muscle morphology. Pain severity was assessed using the visual analogue scale (VAS). Differences in psoas major muscle morphology and pain severity between the two groups were compared. A Pearson correlation analysis was used to examine the relationship between the psoas major muscle index and pain severity. A linear regression model was used to analyze the independent risk factors affecting pain severity. Results There were no statistically significant differences in sex, age, or body mass index between the two groups (P>0.05). The disease duration was longer and the incidence of anxiety and depression was higher in the lumbar and leg pain group than those in the simple lower extremity pain group (P<0.05). Compared with the simple lower extremity pain group, the lumbar and leg pain group showed lower psoas major muscle index [(0.53 ± 0.05) vs. (0.61 ± 0.07)] and higher VAS score [(4.67 ± 1.10) vs. (3.02 ± 0.89)], and the differences were statistically significant (P<0.05). Pearson correlation analysis revealed a negative correlation between the psoas major muscle index and the VAS score (r=−0.288, P<0.05). Linear regression model analysis indicated that the independent risk factors affecting the VAS score were age, disease duration, LDH type, and the psoas major muscle index. Conclusion Compared with LDH patients with simple lower extremity pain, those with lumbar and leg pain demonstrate a longer disease duration, a higher incidence of anxiety and depression, and a higher severity of psoas major muscle atrophy and pain. The severity of pain is associated with not only advanced age and prolonged disease duration but also the LDH type and psoas major muscle atrophy.

Objective To compare the quality of liquids dispensed by intelligent dispensing robot and traditional manual in PIVAS,to ensure the safety of clinical infusion.Methods Using omeprazole and ambroxol as the main drugs and 5％glucose injection and 0.9％sodium chloride solution as the solvent,a number of quality indexes including drug residues and the number of insoluble particles were evaluated in the two modes of manual and robotic dispensing,respectively.Results Under the robot dispensing mode and manual dispensing mode,the residual amount of drugs was less than 5％,the insoluble particles were far less than the limit,the pH value was in line with the human infusion range,and the endotoxin and aseptic culture were negative results,with no statistical significance(P＞0.05).Conclusions The quality of liquid dispensed under the robotic dispensing mode is guaranteed,and there is no significant difference in the quality of liquid dispensed with the traditional manual dispensing mode,which provides a reliable guarantee for the large-scale application of robotic dispensing in intravenous admixture service.

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.

Objective:To investigate the implementation of boxed warning of drug labels in US Food and Drug Administration (FDA) from 2019 to 2024, and compared it with the relevant situations in China, in order to provide reference for the revision of drug labels and safe drug use.Methods:Data on boxed warning revisions in the US FDA "Drugs Safety Related Labeling Changes" Database from January 1, 2019 to December 31, 2024 were retrieved, and the revised contents were classified. The drug labels for newly marketed drugs in the United States during the same period were collected, the boxed warnings were recorded and summarized, and compared with the warning statements in drug labels of relevant drugs approved in China.Results:From 2019 to 2024, FDA revised boxed warnings in 209 drug labels. Among them, 22 items (10.53%) were newly added, 63 items (30.14%) were major updates, 115 items (55.02%) were minor updates, and 9 items (4.31%) were removed. A total of 293 new drugs were approved in the United States from 2019 to 2024, of which 69 (23.55%) had boxed warnings when they were approved, and 4 (1.37%) were added boxed warnings when they were revised in the labels. Up to December 31, 2024, 92 of the 293 new drugs had been approved in China. Compared with the labeling in the United States, some drugs lacked warning statements section in China, including zolpidem tartrate, dexzopiclone, zaleplon, montelukast sodium, denosumab, terlipressin, etc.Conclusions:The warning statements in some Chinese drug labels are inconsistent with the boxed warnings in the American drug labels. It is suggested that the revision of the boxed warning by US FDA should be regarded as one of the new sources of safety information to assess the risks of related drugs and determine whether it is necessary to revise the relevant drug labels in China.

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:To investigate the awareness of medical staff on pharmacovigilance and the current situation of the construction of pharmacovigilance system in medical institutions.Methods:A self-designed questionnaire was sent to medical institutions in China through Professional Committee on Pharmacovigilance Research, China Society for Drug Regulation in the form of Wechat, and medical staff participated voluntarily. The contents of the questionnaire included 23 questions in 4 dimensions, including the basic information of the respondents, their understanding of the concept and regulations of pharmacovigilance, the management of pharmacovigilance, and the reporting and feedback of adverse drug reactions(ADRs)/events in their medical institutions. The survey time was from August 18, 2023 to October 18, 2023. The data from the questionnaire were analyzed descriptively.Results:The collected questionnaires were from medical institutions in 31 provinces, autonomous regions, and municipalities directly under the central government, with a total of over 100 questionnaires collected in each region. A total of 10 991 medical staff participated in the survey, including 5 504 pharmacists, 2 120 doctors, and 3 367 nurses. Among them, 10 131 (92.18%) respondents had heard of pharmacovigilance, 4 511 (41.04%) had participated in pharmacovigilance-related works, 9 368 respondents (86.41%) answered that the ADRs monitoring and management system had been established in medical institutions where they worked, 8 186 respondents (75.51%) answered that leading group for pharmacovigilance (including ADRs monitoring) had been set up in the medical institutions where they worked, 8 605 respondents (79.37%) answered that the pharmacovigilance works was managed by special personnel in the institutions where they worked, 7 859 (72.49%) answered that there were liaison officers in the clinical departments where they worked, 6 043 (55.74%) answered that the individuals would be rewarded for reporting ADRs, 4 809 (44.36%) answered that pharmacovigilance had been included in the daily works and assessment indicators of the departments, and 5 351 (49.36%) answered that reports of ADRs were reviewed by special personnel. Active reporting by medical staff was the main collection channel of ADRs, 3 391 (31.28%) answered they had actively captured ADRs from the hospital information system, and 7 728 (71.28%) answered they had reported ADRs through the hospital information system, 10 061 (92.81%) answered that the monitoring results of ADRs would be regularly fed back in the hospitals where they worked, and 6 239 (57.55%) answered that regular training on pharmacovigilance for all medical staff would be provided in the institutions where they worked.Conclusions:Medical staff have generally heard of pharmacovigilance and are aware of the national pharmacovigilance system, but they still have insufficient understanding of the concept and regulations of pharmacovigilance. The degree of participating in pharmacovigilance works of medical staff in different regions are different. The monitoring and management of ADRs could be paid attention to in the most medical institutions, but the degree of improvement of pharmacovigilance system in different levels of medical institutions is different.
