ObjectiveTo explore the process and guidelines for ethical review in decentralized drug clinical trials， promote clinical trial progress， and ensure drug development progress. MethodsThe key points of the ethical review were summarized by studying the relevant laws and regulations on decentralized drug clinical trials， analyzing the advantages and challenges of decentralized drug clinical trials， and combining the experience of the ethics committee of the institution in reviewing decentralized drug clinical trials. ResultsRelevant laws and regulations were the basis for the ethical review， and the ethics committee should adopt appropriate review methods based on regulations and hospital ethical standard operating procedures. The ethics committee should focus on the feasibility， applicability， and rationality， the adequacy of informed consent， the protection of rights and interests and privacy of subjects， as well as the qualification and standard operating procedures of electronic platforms for conducting decentralized drug clinical trials. ConclusionDecentralized drug clinical trials are in their early stages and urgently require guidance from relevant laws and regulations. Ethical review is also constantly being refined through exploration. It is necessary to supervise the implementation of responsibilities by all parties， pay attention to the rights and interests of subjects， and gradually promote the implementation of decentralized drug clinical trials.

The number of investigator-initiated trials(IIT)projects in medical institutions has increased rapidly,yet there are certain issues such as uneven quality and insufficient consideration of research design.The scientific review and ethical review of IIT complement each other.To improve the research quality and review efficiency of IIT and reduce review repeatability,this paper described the current situation of scientific review and ethical review of IIT in a tertiary A hospital.Combined with literature analysis,the common issues in scientific review and ethical review were summarized into four types:standardization,reliability,safety,and lag.Corresponding to these common issues,the reasons for their occurrence were analyzed as the lack of unified review points,the ambiguity of each review focus,the lack of review communication and exchange,and the lack of ability and awareness of relevant personnel.The explored solutions included establishing a collaborative review mechanism,by unifying the key points of collaborative review,clarifying the review responsibilities of each committee,building a review communication mechanism with the help of information technology,strengthening training and publicity,and other means.These solutions aimed to promote the organic combination of scientific review and ethical review,fully leverage the synergistic effect,improve the efficiency of review,and promote the high-quality and healthy development of IIT.

Objective:This study aims to improve the management level and quality of horizontal scientific research contracts in hospitals, reduce the risk of contract management, and explore an efficient mode of information management of horizontal scientific research contract management.Methods:Taking a Tertiary Grade A hospital as an example, this study described and summarized the management status of horizontal scientific research contracts from 2018 to 2022, sorted out the potential risks and prevention and control nodes of the review, signing, performance, and archiving of horizontal scientific research contracts in the whole cycle management process, and designed an information management model according to the relevant elements of risk prevention and control and the standardized requirements of contract management, thereby developing information platform related functions.Results:The horizontal research contract management function of the clinical research platform based on the integration concept was available to meet the requirements of risk prevention and control of horizontal research contracts, and the contract review and signing cycle of the information management mode was shortened by 33.33% and 31.95% respectively compared with the traditional management mode. The platform realized a standardized whole process management of contract submission, review, repair and revision, signing, performance, and filing.Conclusions:Information management can effectively reduce the risk of horizontal scientific research contract management. It is necessary to strengthen the docking and interaction function with other information platforms and further explore the information auxiliary function to improve the refined management effect of horizontal scientific research contracts.

Objective:To explore the management strategies of conflicts of interest(COI) by analyzing the definition, manifestations, and implications of COI related to clinical research.Methods:This study summarized the definitions and types, manifestations, and implications of different groups of COI in clinical research. It explored the management response of medical institutions to the COI related to clinical research.Results:Conflicts of Interest could be divided into economic and non-economic conflicts of interest, showing different manifestations in different groups. COI occurs in a variety of links involved in clinical research, and the overall disclosure ratio of COI is low, which might have adverse effects on institutions, investigators, clinical research quality, and subjects.Conclusions:COI management should be implemented by strengthening the construction of the COI management system, strictly following the principle of public disclosure, and strengthening education and training, to improve the quality and credibility of clinical research.

Objective To investigate the effect of diosgenin on the proliferation and apoptosis of breast cancer cells and its potential molecular mechanism. Methods The breast cancer cell line MCF-7 was treated with low, medium, and high doses of diosgenin, and cell proliferation was detected through the MMT method. Flow cytometry was used to detect cell apoptosis. Nuclear-cytoplasmic-protein separation method was applied to detect the subcellular localization of death associated protein (DAXX). qRT-PCR and Western blot were used to detect the expressions of DAXX and c-Jun N-terminal kinase pathway (JNK)-related proteins. Results Diosgenin considerably inhibited the proliferation of MCF-7 cells and promoted cell apoptosis in a concentration-dependent manner. Diosgenin can promote the movement of DAXX from nucleus into the cytoplasm. Diosgenin upregulated the expression of cell surface death receptor (Fas), increased the phosphorylation levels of JNK and mitogen activated protein kinase (p38), and activated the JNK/p38 signaling pathway with concentration dependence. Conclusion Diosgenin inhibits the proliferation and promotes the apoptosis of the breast cancer cell line MCF-7, whose mechanism may be related to the regulation of DAXX subcellular localization and the activation of JNK/p38 signaling pathway.

Objective:This study aims to investigate the willingness of subjects to use electronic informed consent and analyze its influencing factors, so as to provide theoretical basis for the promotion of electronic informed consent.Methods:Questionnaires were designed and distributed to subjects through clinical research coordinator. Univariate and multivariate analysis were used to analyze the influencing factors of subjects′ preferred electronic informed consent.Results:All the subjects who had used e-informed consent had a positive evaluation on their overall satisfaction. 57.48% of subjects preferred electronic informed consent. The results of multi-factor analysis showed that age, the degree of concern about privacy disclosure and the electronic form were the 3 influencing factors.Conclusions:Electronic informed consent should be fully informed of the content, the language should be easy to understand, and the subject should be given a fair choice and a voluntary decision. The subject′s privacy must be protected in accordance with laws and regulations during the informed process. We should enhance the preferred willingness of subject to electronic informed consent through the above measures.The future development of electronic informed consent still needs the support of relevant policies, the continuous improvement of technical equipment and the supervision of relevant departments.
