Traditional Chinese medicine （TCM）， through its multi-target and systematic regulatory effects， has demonstrated unique advantages in the treatment of gastric precancerous lesions （GPL）. At present， TCM theoretical research on GPL is mainly reflected in three aspects， the integration of macroscopic syndrome differentiation， the inflammation-carcinoma transformation mechanism， as well as the systematization and scientization of theoretical inheritance from famous TCM practitioners. High-quality evidence-based research findings serve as the foundation for clinical practice guidelines on GPL， and TCM has gained international academic recognition in the field of GPL prevention and treatment. Research on TCM mechanisms has yielded a series of important outcomes in the aspects of signaling pathways， gene expression regulation， cellular epigenetics， histone modification， and intestinal microecology. It is proposed that future research on GPL should focus on four key directions， establishing multi-omics data， exploring targeted intervention strategies on key regulatory nodes， advancing the standardization process of integrated traditional Chinese and western medicine prevention and treatment technologies， and constructing stratified screening and intervention platforms. The in-depth integration of TCM microcosmic mechanism of action with its macroscopic syndrome differentiation and treatment system， coupled with interdisciplinary research， will provide valuable references for the clinical treatment and scientific research of GPL.

Geniposide， the primary active component of the traditional Chinese medicine Gardeniae Fructus， is a water-soluble iridoid glycoside. Pharmacological studies have demonstrated that geniposide exhibits various biological activities， including hepatoprotective， anti-inflammatory， analgesic， neuroprotective， antidepressant effects， and inhibitory activity against ischemia-reperfusion injury. Recent research has revealed its promising potential in preventing and treating diseases such as atherosclerosis and osteoporosis， indicating broad application prospects. Numerous in vitro and in vivo studies indicate that the pharmacodynamic mechanisms of geniposide are primarily associated with the inhibition of inflammatory responses and oxidative stress， improvement of lipid metabolism， and regulation of apoptosis. However， due to its high water solubility and rapid metabolism in vivo， geniposide suffers from low oral bioavailability， which limits its therapeutic efficacy and clinical application. In recent years， various formulations， such as creams， cubic liquid crystals， hydrogels， and liposomes， have been developed to address its bioavailability issues. This article reviewed the latest research progress on the pharmacological activities and formulation development of geniposide by analyzing domestic and international literature from the past decade， aiming to provide a theoretical basis for further research， development， and utilization of geniposide and its formulations.

ObjectiveTo systematically assess the public health governance capacity in Zhejiang Province, to conduct an in-depth analysis of its strengths and weaknesses, so as to provide scientific basis and strategic recommendations for further enhancement. MethodsA systematic collection of policy documents, public information reports, and research literature related to public health governance capacity in Zhejiang Province from 2002 to 2023 was conducted (encompassing a total of 1 263 policy documents, 138 pieces of information reports and 631 research articles). Based on the evaluation criteria suitable for public health systems previously developed by the research team, the basic status and magnitude of change in public health governance capacity in Zhejiang Province was evaluated. Additionally, normative gap analyses were employed to identify the strengths and weaknesses. ResultsZhejiang Province ranked 4th nationwide in terms of public health governance capacity with a score of 733.4 points (1 000.0-point maximum). The province has effectively implemented the principle of health first (scoring 698.5 points in the assessment of health-first strategy implementation) and attached sufficient importance to health-related goals (scoring 658.2 points in the scientific rationality of goal setting). However, the implementation of inter-departmental coordination and incentive mechanisms only scored 178.7 points, the feasibility of management and monitoring mechanisms scored even lower at only 144.0 points, and the coverage of incentive mechanisms scored 286.0 points. ConclusionZhejiang Province has effectively implemented its health first strategy and attached great importance to health targets, but still needs to strengthen cross-departmental coordination mechanisms and health-oriented incentives.

ObjectiveTo investigate the effects of Huangqi Jianzhongtang （HQJZ） on macrophage polarization and fat consumption in cancer cachexia （CC） mice. MethodsUltra-performance liquid chromatography-quadrupole/electrostatic field Orbitrap high-resolution mass spectrometry （UPLC-Q-Orbitrap HRMS） was used to control the quality of HQJZ. （1） In vitro experiment： HQJZ-containing serum was prepared， and the optimal concentration was determined by cytotoxicity assay. Mouse monocyte-derived macrophages （RAW264.7） were cultured and randomly divided into six groups， including a blank group， a classically activated macrophages （M1） group， an alternatively activated macrophages （M2） group， a HQJZ + blank group， a HQJZ+M1 group， and a HQJZ + M2 group. The relative expression of macrophage marker genes CD86， inducible nitric oxide synthase （iNOS）， CD206， and arginase-1 （Arg1） was detected by real-time quantitative polymerase chain reaction （Real-time PCR ）. （2） In vivo experiment： Thirty-two BALB/c mice were randomly divided into a control group， a model group， a medroxyprogesterone acetate （MPA） group， and a HQJZ group. Except for the control group， the other mice were injected with CT-26 colon cancer cells to establish a CC model. Mice in the MPA and HQJZ groups were given MPA （0.13 g·kg^-1·d^-1） or HQJZ （13.13 g·kg^-1·d^-1） by gavage， respectively， while mice in the control and model groups were given an equal volume of saline by gavage， with interventions continued for 10 d. Real-time PCR was used to detect the expression of macrophage markers （iNOS， Arg1， CD86， CD206） and fat browning-related genes uncoupling protein 1 （UCP1） and peroxisome proliferator-activated receptor γ （PPARγ） in epididymal adipose tissue. Western blot （WB） was used to detect protein expression levels of UCP1 and PPARγ. Micro-computed tomography （micro-CT） was used to measure residual fat volume， and hematoxylin-eosin （HE） staining was used to assess fat browning and calculate pathological scores. ResultsIn vitro， the dominant effective concentration of HQJZ-containing serum was 12.5%. Real-time PCR results showed that， compared with the blank group， Arg1 expression decreased in the HQJZ+blank group （P<0.05）， CD206 showed a downward trend without statistical significance， while iNOS and CD86 expression were significantly increased （P<0.05）. Compared with the M1 group， Arg1 and CD206 expression decreased in the HQJZ+M1 group （P<0.05）. Compared with the M2 group， CD206 expression decreased in the HQJZ+M2 group （P<0.05）， CD86 expression increased significantly （P<0.01）. In vivo， Real-time PCR results showed that， compared with the control group， CD86 and CD206 expression levels were significantly increased in the model group （P<0.01）. Compared with the model group， CD206 expression in the MPA group was significantly decreased （P<0.01）. In the HQJZ group， CD206 was significantly decreased （P<0.01）. WB results showed that， compared with the model group， protein expression of UCP1 and PPARγ was significantly reduced in the HQJZ group （P<0.05， P<0.01）. micro-CT results showed that the total white fat volume in the HQJZ group was greater than that in the model group （P<0.05）. HE staining results showed that pathological scores in the HQJZ group were lower than those in the model group （P<0.05）. ConclusionHQJZ may inhibit white adipose tissue browning by promoting macrophage M1 polarization and suppressing M2 polarization， thereby delaying fat consumption in CC mice.

Organ transplantation is a vital means of saving patients with end-stage diseases, and organ donation serves as its foundation. China’s cadaveric organ donation system adopts a dual model that recognizes both individual autonomy and next-of-kin decision-making rights. However, in practice, the next-of-kin decision-making rule faces multiple challenges, including a narrow scope of eligible decision-makers, inefficient decision-making processes, the misuse of revocation rights and the absence of disqualification mechanisms. This article explores the legal nature of next-of-kin decision-making rights and reflects on the existing rules. By integrating the principles respect, ‘non-maleficence, beneficence, and justice’ in medical ethics, it proposes three pathways for reform: hierarchical ordering of decision-makers, limitation of revocation rights, and legal codification of disqualification grounds. The aim is to balance individual autonomy, family ethics and public interest, realign the cadaveric organ donation system with its altruistic essence and public-oriented mission, and promote the development of organ donation in China.

ObjectiveTo develop a community-family management model for older adults with mild cognitive impairment (MCI) and to formulate detailed application specifications, and to fully leverage the initiative of communities and families under limited resource conditions, for achieving community-based early detection and early intervention for older adults with MCI. MethodsA systematic literature review was conducted to identify pertinent publications. Corpus-based research methodologies were employed to extract, refine, integrate and synthesize management elements, thereby establishing the specific content and service processes for each stage of the management model. Utilizing the 5W2H analytical framework, essential elements such as management stakeholders, target populations, content and methods for each stage were delineated. The model and its application guidelines were finalized through expert consultation and demonstration. ResultsAn expert evaluation of the management model yielded mean scores of 4.84, 4.32 and 4.84 for acceptability, feasibility and systematicity, respectively. By integrating the identified core elements with expert ratings and feedback, the final iteration of the community-family management model for older adults with MCI was formulated. This model comprised of five stages: screening and identification, comprehensive assessment, intervention planning, monitoring and referral pathways to ensure implementation, and enhanced support for communities, family members and caregivers. Additionally, it included 18 specific application guidelines. ConclusionThe proposed management model may theoretically help delay cognitive decline, improve cognitive function and potentially promote reversal from MCI to normal cognition. It may also enhance the awareness and coping capacity of older adults and their families, strengthen community healthcare professionals' ability to early identify and manage MCI.

Objective The causal relationship between endometriosis(EMs)and 15 trace elements including copper,calcium,carotene,folic acid,iron,magnesium,potassium,selenium,vitamin A,vitamin B12,vitamin B6,vitamin C,vitamin D,vitamin E and zinc was analyzed by double sample Mendelian randomization(MR).Methods Multiple trace elements were used as exposure factors,and the incidence risk of EMs was used as the outcome factor for two-sample MR analysis.The data were sourced from the publicly available integrative epidemiology unit open Genome-Wide Association Studies database and Finnish Genome Research Project database.Five Mendelian randomization analysis methods were employed to investigate the causal relationship between EMs and trace elements.Additionally,sensitivity analysis was carried out to evaluate the influence of heterogeneity and horizontal pleiotropy on the results of the MR analysis.Results The impact of trace elements on various types of EMs varies.The results of the inverse variance weighted(IVW)method indicated that trace element calcium(OR=1.465,95％CI:1.094-1.962)and vitamin B6(OR=1.580,95％CI:1.146-2.178)might be risk factors for ovarian EMs.Vitamin B6(OR=0.203,95％CI:0.044-0.939)may be a protective factor for tubal EMs.The above research results were not affected by heterogeneity and horizontal pleiotropy(P＞0.05).This study did not find a causal relationship between other trace elements and EMs.Conclusion The trace elements calcium and vitamin B6 predicted by genetics may play a regulatory role in the development of EMs.

OBJECTIVE To investigate the current status of infection control departments setting,allocation of in-fection control professionals and their position competence in the secondary,tertiary traditional Chinese medi-cine institutions of Beijing.METHODS The questionnaire survey was conducted for all of the secondary and tertiary traditional Chinese medicine institutions in Beijing by Beijing Traditional Chinese Medicine Hospital Infection Man-agement Quality Control Center from Feb.17,2023 to Apr.11,2023.The content of the survey involved the in-formation of the hospitals,setting information of infection control departments and allocation of infection control professionals.RESULTS Totally 59 traditional Chines medicine medical institutions were involved in the survey,35(59.32％)were tertiary hospitals.The median of opened beds was 331(155,479)in the first quarter of 2023.The median of equipped infection control professionals was 4(3,5).The number of infection control professional e-quipped in 67.80％of the medical institutions conformed to requirements of"Notice regarding to further strength-en the management of infection control professionals allocation in medical institutions"released by The Joint Pre-vention and Control Mechanism of the State Council for the Response to the Novel Coronavirus Pneumonia Epi-demic in Aug.2021,with the ratio of infection control professionals to beds 1∶94.20.The principals in charge of the infection control department who had the qualifications for senior professional and technical position and en-gaged in infection control for more than 5 years accounted for 20.00％.Among the infection control professionals,nurses accounted for 49.17％,doctors 41.67％,other professionals 9.17％.CONCLUSIONS There is relatively adequate quantity of the infection control professional equipped in the secondary and tertia-ry medical institutions of Beijing,however,the principals in charge of the infection control department who had the qualifications for senior professional and technical position and engaged in infection control for more than 5 years are very scarce.It is necessary to further optimize the structure of the infection control professionals.

Objective To explore the characteristics of gastric emptying in the whole process of drinking water for colonoscopy in the elderly,and to develop an elderly-friendly drinking water program,thereby improving the comfort and the quality of bowel preparation.Methods From April to September 2024,gastric ultrasound was used to monitor gastric emptying indicators in the whole process of drinking water for colonoscopy in the elderly,summa-rizing its physiological features.On this basis,in October 2024,through literature review and expert argumentation,a bowel preparation drinking water program that meets the characteristics of gastric emptying in the elderly was de-veloped.A convenience sample of 90 elderly patients scheduled for colonoscopy at 2 tertiary hospitals in Beijing was enrolled from November 2024 to January 2025.A non-concurrent controlled trial was conducted:an experimen-tal group from December 2024 to January 2025 received the new elderly-friendly drinking water program,while a control group in November 2024 followed the conventional program.Outcomes included drinking comfort assessed via Visual Analogue Scale(VAS),adverse events,total fluid intake volume and bowel preparation quality via Boston Bowel Preparation Scale(BBPS).Results The experimental group demonstrated superior VAS score(P＜0.05),bowel preparation quality(P＜0.05),total fluid intake(P＜0.05),and higher compliance with optimal stool consistency(P＜0.05),compared to the control group.The experimental group also exhibited a lower incidence of adverse events(P＜0.05).No significant difference was observed in total bowel preparation duration between 2 groups(P＞0.05).Conclusion The bowel preparation drinking water program based on the characteristics of gastric emptying in the elderly improved solution intake tolerance and bowel preparation quality,with practical implications for clinical implementation.

Objective To investigate the current status and barriers to implementing non-accompanied care services in medical institutions in Zhejiang Province,and to provide a basis for the improvement of standardized management of such services.Methods A self-designed questionnaire was conducted from September to October 2024 among all secondary and tertiary medical institutions in Zhejiang Province to assess the implementation status and barriers to non-accompanied care services.Results A total of 397 questionnaires were distributed,with 389 valid responses,yielding a valid response rate of 97.98％.Non-accompanied care services were implemented in 118 institutions(30.33％).Among these,90 institutions(76.27％)had established management systems for non-accompanied wards;71 institutions(60.17％)had a medical nursing assistant-to-bed ratio lower than 1∶5;41 institu-tions(34.75％)provided tiered training for medical nursing assistants;93 institutions(78.81％)required patients to bear the full cost of the service.Compared with secondary medical institutions,tertiary medical institutions have more complete management system for non-accompanied care services.The main obstacles hindering the development of non-accompanied care services include an imperfect management system for non-accompanied wards,a shortage of medical nursing assistants,a lack of standardized training for such assistants,inconsistent charging standards,and low acceptance among patients and their families.Conclusion The promotion of non-accompanied care services in medical institutions in Zhejiang Province has achieved initial success.However,challenges persist,including incomplete management systems,uneven development across hospital tiers,and imperfect charging mechanisms.It is recommended that relevant authorities strengthen policy support,enhance standardized training for healthcare nursing assistants,refine cost-sharing mechanisms,and improve the quality and sustainability of non-accompanied care services through multi-party collaboration.
