ABSTRACT
The seventh article of Measures for the Ethical Review of Biomedical Research Involving Humans (2016) stipulated that medical and health institutions without an ethics committee shall not carry out biomedical research involving Humans. The Opinions on Strengthening the Governance of Ethics in Science and Technology, issued in March 2022, clearly stated that the institutions that do not meet the conditions for establishing a scientific and technological ethics (review) committee should entrust other institutions to conduct the review. The fourteenth article of Measures for Ethical Review of Life Science and Medical Research Involving Humans (2023) proposes that if an institution, which carries out life science and medical research involving humans, has not established an ethics committee or its ethics committee is not competent for ethics review, it can entrust a competent ethics committee or regional ethics committee in writing to carry out ethical review. Most medical institutions at or above the second level in China have set up ethics committees. While most universities and colleges, scientific research institutions, enterprises and grass-roots medical and health institutions have not set up ethics committees, which lack a working system to protect the safety and interests of the participants, and is difficult to conduct life sciences and medical research involving humans. At present, there is a need for some research institutions that do not have the conditions to establish ethics committees to entrust their projects of life science and medical research involving humans to other institutions for ethical review. The entrusted review is still in the exploratory stage, and there is no relevant specification. The hasty implementation of entrusted review may not achieve the goal of effectively protecting the safety and interests of the participants, and even cause legal disputes. Based on the thematic discussion, with reference to the relevant laws and regulations, departmental rules, ethical standards, and the experience of the ethics committees of some domestic institutions in implementing the entrusted review, the guideline was formulated for the reference of the current entrusted review to ensure the safety and interests of the participants.
ABSTRACT
The use of human biological specimen has great significance to the development of biomedicine. Meanwhile, the powerful electronic data set with sophisticated analytic techniques creates challenge to the protec-tion of private information. As for the research with human biological specimen, how to facilitate the research con-duct on the basis of ethical principles is one of the key considerations when the US Department of Health and Hu-man Service initiated the revision of Code of Federal Regulations ( CFR) -theCommon Rule for subject protec-tion. The Notice of Proposed Rulemaking ( NPRM) proposed:Respect for autonomy will be enforced by broad con-sent to enforce and waiver of consent intend to be rare;If the research risks only involve privacy protection, review process will be simplified under the premise of ensuring the implementation of privacy laws and other protective measures. The paper introduced the revisions related to the researches using human biological specimen in NPRM, analyzed the terms of broad consent, exemption and exclusion, and explored the elicitation to ethical review prac-tice in China.
ABSTRACT
From the point of view of ethics review work situation of our country, the existing capacity of our review of ethical problems in development are analyzed, a preliminary summary of the Chinese medicine ethics review ca-pacity development, systematically analyzes the Assessment Human Research Protection System of TCM and Chinese medicine clinical research ethics review platform evaluation work, and to improve the ethical review system to perfect supervision system, improve the medical ethics review standards and guidelines, carrying out the innovation and con-struction of ethical review professional knowledge training, to promote Chinese medicine ethics review certification and accreditation system construction work and Chinese medical ethics review of the clinical research objective, the practice of ethical review management of Chinese medicine are discussed.
ABSTRACT
In September 2012, the Assessment for Ethics Review of Traditional Chinese Medicine (TCM) Re-search with Human Participants (named CAP, Chinese medicine assessment human research protection system) was officially commissioned to the World Federation of Chinese Medicine Societies to organize by the State Ad-ministration of TCM. Through the assessment of 20 medical institutions, a comprehensive analysis on ethical re-view platform was conducted. Combined with current regulatory system of ethics in the U.S., this article discussed independent assessment on important CAP features of local brands, the practice and benefit of construction pro-motion based on assessment and continuous improvement, as well as the importance of vigorously promote CAP assessment .
ABSTRACT
Objective To summarize the experience of establishing the stable rat model of chronic allograft nephropathy. Methods We used Fisher rats as donors and Lewis rats as recipients.After the left kidney of the donor perfused in situ under hypothermic condition, the left renal vein,abdominal aorta and bladder flap of the donor was anastomosed with the left renal vein, renal artery and bladder of the recipient, respectively. The recipients were given cyclosporin oral solution 10 mg/kg every day by gavage for 10 days after transplantation. The blood and urine samples were collected 1 month, 2 months and 4 months after transplantation and renal function and total urine protein were examined. The pathological changes of the renal allograft were observed 2 and 4 months after transplantation. Results Forty-five rats received operation and achievement ratio was 85%. The renal transplantations were finished in 120 ± 20 min. The Scr, BUN, Cycs and total urine protein demonstrated a significant increase one month after transplantation. On the second and fourth month,with the exception of urine protein continued to increase, the other indicators did not change significantly. Two months after transplantation renal pathology demonstrated light to moderate interstitial fibrosis, infiltration of lymphocytes and plasma cells. At 4th month the renal allografts showed extensive interstitial fibrosis, a large number of infiltrating interstitial cells, thickening,hardening, occlusion of glomerular basement membrane, and renal tubular atrophy that were consistent with pathological changes of chronic allograft nephropathy. Conclusion Through adequate surgical training and improvement, and specification for rat nephrectomy, transplantation surgery,and postoperative management in every detail, the model with high success rate and stability can be achieved.
ABSTRACT
It's a hard but imperative research subject for postgraduate to study medical English in TCM colleges.For more than 3 years,Nanjing University of TCM has obtained good effect in such a field and their practices include adopting original edition of textbooks,selecting medical professionals who are good at English as teachers rather than English teachers who have some medical knowledge.Our teaching methodology is continuous,large volume fast reading.
ABSTRACT
Intravenous preparations take more risk than oral preparation and externally applied agent.In phaseⅠtoler- ance trial of intravenous preparations of TCM on human subjects,minimum dose and maximum dose should be decided in light of data derived from preclinical pharmacodynamic and toxicological experiments,combined with practical situation in clinic.Dose-ascending coefficient of the should be reasonable.During the application of intravenous preparations of TCM in tolerance trial,clinical monitoring must be done to ensure the safety of subjects.Overall and integrated observa- tional indices should be designed on the basis of the features of preparation types,administration methods,the nature of medicine,etc.,so as to provide full-scale data for safe dose range,concentration of the preparation,dripping veloci- ty and possible adverse reactions,etc.
ABSTRACT
Objective: To explore the operating procedure for designing the randomized scheme of multi-center clinical trial. Methods: SAS randomized program was written in accordance with the randomized parameters and stipulated randomized rules of centers, cases and blocks. The design of the SAS randomized program adopts the same seed in multi-hierarchical factors, and the principles of succession and repeatability of the randomized code. Results: This program can produce randomized numbers and complete the design and permutation of randomized codes in a standard and convenient way.
ABSTRACT
Bias in undoubled blind design in the clinical trial of Chinese herb affects the evaluation of efficacy and safety. With two examples, the paper recommended a "segregation" technique to minimize the bias in investigators during undoubled blind trial. The results showed that this method combined other strict means can achieve the conclusions the same as a double blind trial.
ABSTRACT
Kidney transplantation is a high-cost and high-risk surgery,thus genuine informed consent from the patients and their family members is indispensable both for protecting rights of patients and ensuring medical safety.Guided by related regulations and ethical guidelines,this paper proposes necessary information which should be provided for patients,one example of Informed Consent Form(ICF) composing of information sheet,and consent signature form offered for reference.The proposed ICF applies three accepted requirements for informed consent,i.e.,completely being informed,fully understood and free to make choice.
