As a distinctive resource of Chinese civilization, traditional Chinese medicine (TCM) technology transfer faces significant opportunities under the background of digital and intelligent transformation, while also being constrained by unique challenges such as the complexity of its theoretical system, lengthy industrial chains, and multidimensional policy restrictions, resulting in a "high-value-high-threshold" paradox. At present, TCM technology transfer is deeply trapped in a "threefold reluctance" dilemma, i.e., unwillingness to transfer, inability to transfer, and lack of capacity to transfer. Specifically, the disconnection between scientific research evaluation systems and market demand leads to low conversion rates of research achievements, unclear ownership and compliance risks suppress innovation incentives, and the absence of professional services intensifies supply-demand mismatches. This article systematically analyzes the specific characteristics of TCM technology transfer and proposes a breakthrough pathway centered on full-chain digital and intelligent transformation. By integrating technologies such as intelligent sorting systems, blockchain-based traceability, and AI diagnostic models, the TCM ecosystem spanning "cultivation-production-service" can be reconstructed. In terms of standardization, promoting the progression from "experience-based data conversion" to "data standardization" and further to "intelligent standardization" is advocated to resolve quality control challenges. For example, a "three-no-one-full" certification system can strengthen quality trust. Policy coordination should focus on optimizing mechanisms for the transformation of scientific and technological achievements, while exploring intellectual property securitization and risk-sharing models to stimulate research momentum. In terms of internationalization, reliance on the Belt and Road Initiative platform to promote the export of geo-authentic medicinal material brands and standards is recommended to build a dual-driven model of "technology plus culture". Looking ahead, through the construction of national-level databases, the cultivation of interdisciplinary talent, and the mutual recognition of international standards, a new paradigm of "scientific intelligent manufacturing" can be formed, providing systematic solutions for the modernization of TCM and global health governance.

OBJECTIVE To clarify the roles and functions of full-time pharmacists in the management of early-phase clinical trials of antineoplastic drugs, and to provide theoretical and practical support for their transformation from traditional drug managers to multi-dimensional roles in clinical research. METHODS Combined with relevant regulations such as the Good Clinical Practice (GCP) (2020 Edition), and based on the clinical practice experience of the Phase Ⅰ Clinical Ward in our hospital, this study systematically sorted out full-time pharmacists’ roles and functions in early-phase clinical trials of antineoplastic drugs, and explored the core challenges and optimization pathways for role transformation and capacity-building of domestic full-time clinical trial pharmacists. RESULTS & CONCLUSIONS Full-time pharmacists assumed multiple roles in early-phase clinical trials of antineoplastic drugs, including providing pharmaceutical support for protocol design, implementing whole-process standardized management of clinical trial drugs, ensuring medication safety for clinical trial subjects/participants, conducting quality control throughout the clinical trial process, and serving as a bridge for interdisciplinary collaboration and communication. Currently, there are challenges in this field in China, such as unclear roles, an imperfect capacity building system, and insufficient regulatory support. This paper proposes that by establishing a standardized role framework, clarifying the core responsibilities and authorities of full-time pharmacists, and leveraging cutting-edge technologies to provide comprehensive support for their roles, so as to fully harness their pharmaceutical expertise and contribute to the standardization and efficiency of the antineoplastic new drug development process.

Objective To investigate the effect of bone metabolic markers on sarcopenia in elderly patients with type 2 diabetes mellitus (T2DM). Methods A total of 412 patients with T2DM in the department of endocrinology of Nanjing Central Hospital from May 2020 to June 2025 were selected as the research subjects. According to Asian Working Group for Sarcopenia (AWGS) in 2019, these patients were evaluated for skeletal muscle mass index (ASMI), muscle strength, and muscle function, and were divided into a sarcopenia group (84 cases) and a non-sarcopenia group (328 cases). The glucolipid metabolic indexes were detected in both groups of patients, and the bone metabolic markers were evaluated, including procollagen type 1 N-terminal peptide (P1NP), beta-C-terminal telopeptide of type 1 collagen (β-CTX), and 25-hydroxy vitamin D [25-(OH)D]. The factors influencing the occurrence of sarcopenia in T2DM patients were analyzed by logistic regression analysis, and the diagnostic values of bone metabolic markers on sarcopenia in patients with T2DM were assessed by ROC curve. Results The levels of P1NP and 25-(OH)D were lower, while β-CTX level was higher in the sarcopenia group compared to the non-sarcopenia group, with statistical differences (P<0.05). After logistic correlation analysis, it was found that P1NP, β-CTX and 25-(OH)D were all influencing factors for the occurrence of sarcopenia in T2DM patients. ROC curve analysis suggested that combined detection of PINP, β-CTX, and 25-(OH)D had higher diagnostic value, with an area under the curve up to 0.805. Conclusion The abnormal expression of bone metabolic markers is associated with the increased risk of sarcopenia in patients with T2DM. The detection of serum bone metabolic markers expression level is of certain significance for the assessment of diabetes-related sarcopenia.

Objective:
To analyze the trajectories of blood pressure and body mass index (BMI) among primary and secondary school students aged 7-17 in Shunyi District of Beijing, and to explore the association between different growth trajectories and visual outcomes, so as to provide a scientific basis for the prevention and control of common diseases in children and adolescents.
Methods:
Health examination data (including vision, blood pressure and BMI) of primary and secondary school students in Shunyi District of Beijing from 2019 to 2023 were collected and analyzed. Group based trajectory modeling was used to classify the trajectories of BMI and blood pressure (systolic and diastolic) into distinct groups among students aged 7-17 years. The relationship between these trajectories and visual outcomes was examined using binary Logistic regression analysis.
Results:
The prevalence of screening myopia among students in Shunyi District was 57.2%, while the rate of moderate to severe visual impairment was 55.8%. Based on the latent growth model, the trajectories of systolic blood pressure, diastolic blood pressure, and BMI were divided into three groups:low growth trajectory, moderate growth trajectory and high maintenance trajectory. Logistic regression analysis revealed that, compared to the low growth trajectory group, the moderate growth and high maintenance trajectory groups for systolic blood pressure, diastolic blood pressure, and BMI were associated with an increased risk of screening myopia ( OR =1.14, 1.11; 1.07, 1.19 ; 1.06, 1.08, P <0.05). Similarly, the moderate growth and high maintenance trajectory groups for systolic blood pressure, diastolic blood pressure, and BMI were similarly associated with an increased risk of moderate to severe visual impairment ( OR = 1.12 , 1.12; 1.09, 1.17; 1.08, 1.11, P <0.05).
Conclusions
Moderate growth and high maintenance trajectories of blood pressure and BMI are associated with an increased risk of screening myopia and moderate to severe visual impairment among students. It is recommended to closely monitor changes in blood pressure and overweight/obesity trajectories in primary and secondary school students, conduct regular assessments, and actively prevent the development and progression of multimorbidity and comorbidity.
5.Changes in the body shape and ergonomic compatibility for functional dimensions of desks and chairs for students in Harbin during 2010-2024
Chinese Journal of School Health 2025;46(3):315-320
Objective:
To analyze the change trends in the body shape indicators and proportions of students in Harbin from 2010 to 2024, and to investigate ergonomic compatibility of functional dimensions of school desks and chairs with current student shape indicators, so as to provide a reference for revising furniture standards of desks and chairs.
Methods:
Between September and November of both 2010 and 2024, a combination of convenience sampling and stratified cluster random sampling was conducted across three districts in Harbin, yielding samples of 6 590 and 6 252 students, respectively. Anthropometric shape indicators cluding height, sitting height, crus length, and thigh length-and their proportional changes were compared over the 15-year period. The 2024 data were compared with current standard functional dimensions of school furniture. The statistical analysis incorporated t-test and Mann-Whitney U- test.
Results:
From 2010 to 2024, average height increased by 1.8 cm for boys and 1.5 cm for girls; sitting height increased by 1.5 cm for both genders; crus length increased by 0.3 cm for boys and 0.4 cm for girls; and thigh length increased by 0.5 cm for both genders. The ratios of sitting height to height, and sitting height to leg length increased by less than 0.1 . The difference between desk chair height and 1/3 sitting height ranged from 0.4-0.8 cm. Among students matched with size 0 desks and chairs, 22.0% had a desk to chair height difference less than 0, indicating that the desk to chair height difference might be insufficient for taller students. The differences between seat height and fibular height ranged from -1.4 to 1.1 cm; and the differences between seat depth and buttock popliteal length ranged from -9.8 to 3.4 cm. Among obese students, the differences between seat width and 1/2 hip circumference ranged from -20.5 to -8.7 cm, while it ranged from -12.2 to -3.8 cm among non obese students.
Conclusion
Current furniture standards basically satisfy hygienic requirements; however, in the case of exceptionally tall and obese students, ergonomic accommodations such as adaptive seating allocation or personalized adjustments are recommended to meet hygienic requirements.

ObjectiveTo study the regulatory effects of Yinchenhao Tang combined with Yinchen Zhufu Tang on the expression of regulatory T (Treg)/helper T 17 (Th17) cells cultured in vitro from the patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). MethodsFresh peripheral blood was collected from the patients with HBV-ACLF for the separation of peripheral blood mononuclear cells (PBMCs). Immunomagnetic beads were used to isolate primary Treg and naive CD4+ T cells. After in vitro expansion, naive CD4+ T cells were induced to differentiate into Th17 cells. Rats were treated with the clearing method (Yinchenhao Tang), warming method (Yinchen Zhufu Tang), and combination of clearing method with warming method (Yinchenhao Tang combined with Yinchen Zhufu Tang, also known as Wenyang Jiedu Huayu Prescription), respectively, and then the medicated plasma samples were collected. Meanwhile, blank plasma was collected from the rats treated with normal saline. Cells were classified into blank, clearing method (5.04 g·kg-1), warming method (6.21 g·kg-1), and combination of clearing method with warming method (17.1 g·kg-1) groups and treated with corresponding plasma. The frequency of Treg/Th17 cells was detected by flow cytometry. The level of transforming growth factor-β (TGF-β) was measured by the enzyme-linked immunosorbent assay. The cytometric bead array (CBA) was employed to measure the levels of interleukin-10 (IL-10), interleukin-17A (IL-17A), tumor necrosis factor-α (TNF-α), and interleukin-23 (IL-23). The mRNA and protein levels of Forkhead box P3 (FoxP3) and retinoic acid-related orphan receptor-gamma t (ROR-γt) were determined by Real-time PCR and Western blot, respectively. ResultsCompared with the blank group, the combination of clearing method with warming method group showed decreased frequency of Treg and Th17 cells, lowered levels of Treg cytokines (TGF-β and IL-10) and Th17 cytokines (TNF-α, IL-17A, and IL-23), and down-regulated mRNA and protein levels of FoxP3 and ROR-γt (P<0.01). Compared with the clearing method group, the combination of clearing method with warming method group showed decreased Treg cell frequency and down-regulated mRNA and protein levels of FoxP3. Meanwhile, the combination group showed decreased Th17 cell frequency, lowered levels of TGF-β, IL-10, TNF-α, IL-17A, and IL-23, and down-regulated mRNA and protein levels of ROR-γt (P<0.05, P<0.01). Compared with the warming method group, the combination of clearing method with warming method group showed decreased frequency of Treg cells and down-regulated mRNA and protein levels of FoxP3. Meanwhile, the combination group showed decreased Th17 cell frequency, declined levels of TGF-β, IL-10, TNF-α, IL-17A, and IL-23, and down-regulated mRNA and protein levels of ROR-γt (P<0.05). ConclusionThe combination of clearing method with warming method can down-regulate the expression of specific cytokines of Treg and Th17 cells, inhibit the over activation of Treg and Th17 cells, and reduce the secretion of cytokines such as TGF-β, IL-10, TNF-α, IL-17A, and IL-23, thereby alleviating inflammation and improving the prognosis of the patients with liver failure.

ObjectiveTo investigate the differential expression of intestinal flora in patients with different traditional Chinese medicine (TCM) syndrome types (Yang Huang syndrome, Yin-Yang Huang syndrome, and Yin Huang syndrome) of hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) and clarify the biological basis of jaundice and Yin Huang syndrome in liver failure. MethodsA total of 20 cases of HBV-ACLF patients were included in the Yang Huang group, 20 cases in the Yin-Yang Huang group, 16 cases in the Yin Huang group, and 20 healthy adult volunteers. 16S rRNA gene sequencing was used to detect the diversity, species distribution, and differences of the subjects' intestinal flora, and bioinformatics analysis was conducted. ResultsCompared with those in the healthy control group, the species richness and diversity of intestinal flora in the HBV-ACLF Yang Huang group, Yin-Yang Huang group, and Yin Huang group were significantly reduced, and there were significant differences in the composition of intestinal flora compared with healthy volunteers. However, there were no significant differences in the species richness, diversity, and composition of intestinal flora among the three groups. LEfSe analysis showed that compared with the healthy control group, the HBV-ACLF Yang Huang group showed significant enrichment of Staphylococcus aureus(P<0.01). Yin-Yang Huang group showed significant enrichment of s_Ileibacterium valens(P<0.05,P<0.01), and the Yin Huang group showed significant enrichment of Enterococcus faecium and Streptococcus sali varius(P<0.05). These strains may be biomarkers between the three groups of patients and the healthy control group. Compared with that in the Yin-Yang Huang group, Tyzzerella_nexilis was significantly enriched in the Yang-Huang group, and Streptococcus lactiae was significantly enriched in the Yin-Yang Huang group. Compared with that in the Yang-Huang group and the Yin-Yang Huang group, Enterococcus faecalis was significantly enriched in the Yin Huang group. The above strains may be biomarkers among the three groups of patients, and Enterococcus faecium may be a biomarker for the transition from the Yang Huang group to the Yin Huang group. ConclusionsThere are significant differences in the intestinal flora between patients with HBV-ACLF Yang Huang syndrome, Yin-Yang Huang syndrome, and Yin Huang syndrome. Enterococcus faecium is significantly enriched in the Yin Huang syndrome group, suggesting that dysbiosis of the intestinal flora may be the biological basis for jaundice and Yin Huang syndrome in liver failure.

Objective To evaluate the current status in the implementation of GBZ/T 201.5-2015 Radiation shielding requirements for radiotherapy rooms-Part 5: Radiotherapy room of proton accelerators, identify issues in the application of its technical indicators, and provide a basis for the in-depth implementation and further revision of the standard. Methods In accordance with the Standardization Law of the People’s Republic of China and the Guidelines for Health Standards Tracking Evaluation (WS/T 536-2017), a combination of cluster sampling and stratified sampling methods was employed to select professionals involved in proton accelerator radiotherapy devices and facilities in three provinces (or municipalities directly under the central government) as the subjects of the survey. A questionnaire was developed to collect basic information about the subjects and their understanding and application of the technical indicators in the standard. A standard evaluation indicator system with a total score of 100 points was established to score the implementation of the standard (40 points), the technical content (30 points), and the effectiveness of the implementation (30 points). Results A total of 169 professionals from 107 institutions participated in the survey, with 79.88% of the respondents having at least 5 years of experience in radiation therapy and 74.56% holding intermediate or higher professional titles. The score of standard implementation was 18.3 points. The awareness rate exceeded 80%, indicating a high level of awareness about the standard. However, the scores for the dissemination and application of the standard were relatively low, accounting for 28% and 32% of their respective full marks. The technical content of the standard and the effectiveness of its implementation scored 27.0 and 26.6 points, respectively. The overall score in the evaluation of standard implementation was 72 points, with scores of 68.6, 72.3, and 75.0 for Beijing City, Shanghai City, and Jiangsu Province, respectively. Conclusion GBZ/T 201.5-2015 Radiation shielding requirements for radiotherapy rooms-Part 5: Radiotherapy room of proton accelerators is scientific and operable, and it is well-coordinated with relevant laws and standards. However, considering the development in FLASH technology and multi-chamber radiotherapy room, it is necessary to revise and improve the standard.
