The scientific research on prevention and control of coronavirus disease 2019 (COVID-19) has been a major and urgent task, of which clinical trials occupy a pivotal position in the entire prevention and control system. 204 relative clinical trials of traditional Chinese medicine (TCM) have been registered on Chinese Clinical Trial Registry. Through the analysis of all online public protocols of registered trials, it is found that the clinical studies of TCM in China showed lack of research foundation, tight time and heavy tasks, difficult clinical implementation, and disturbance by changes of the epidemic status. Based on these characteristics, this paper put forward several thoughts and suggestions on the quality management and design improvement for clinical trials of TCM preventing and treating COVID-19, in order to improve the quality of clinical trials in China, provide effective supports for the public health decision-making on the epidemic, and also give a reference for the prevention and control of epidemics in the future.
The use of core outcome sets reduces heterogeneity in the reporting of outcomes in clinical trials, increasing the value and significance of research. This paper first introduces and interprets “core outcome sets for myocardial infarction (COS-MI) in clinical trials of traditional Chinese medicine and Western medicine”, in order to help Chinese researchers better understand and use it. Second, this study surveyed the use of COS-MI in MI related clinical trials from January 1, 2023 to June 1, 2024, showing that 91% (10/11) of the 35 acute myocardial infarction clinical studies included reported core outcomes, and the median percentage of using core outcome sets was only 36% (4/11). As the publication time of the core outcome set is close to the literature search time, the understanding of domestic researchers about it is still unclear. Further research is needed to explore the application of core outcome sets for myocardial infarction in clinical trials of traditional Chinese medicine and Western medicine, providing a reference for its update and improvement.
To investigate the shortsegment pedicle screw in treating degenerative L4 spondylolisthesis and the relationship of the preliminarily bending degree of the titanium rod with the lumbar lordosisangle, the slipping angle and the slipping percentage and to evaluate the clinical coincidence and curative effects of the preliminarilybent rod. MethodsFrom September 2005 to March 2007, 31 female patients (age, 40-70 years; average, 58.3 years) were admitted for surgical treatment of their L4 degenerative spondylolisthesis (MeyerdingⅠ°, Ⅱ°)． Their lumbar lordosis angle （x1）, slipping angle (x2), and slipping percentage (x3) were measured in the L4,5 segment before operation. During the operation, the titanium rod bent beforehand according to the corresponding standards was inserted. The angle of the bent rod (Y) was measured, and then the multiple linear regression equation was established. The regression equation was applied to the surgical treatment of the 30 patients.Results According to the criteria in the JOA scoring system, the 31 patients had scores of 8.300± 1.080 and 26.916±1.859 before operation and after operation, respectively. There was a significant difference between before operation and after operation（Plt;0.05）. The established multiple linear regression equation was as follows:Y=0.1390-0.327logx1+0.463x2+0.288x32．The operating time was 51.290±3.408 min in the 30 patients who underwent an insertion of the preliminarilybent rod during the operation; however, the operating time was 102.360±5.004 min in the 31 patients who underwent an insertion of the bent rod that was made based on experience during the previous operations. There was a significant difference in the operating time between the two kinds of the rods （Plt;0.05）. Estimated according to 90%, 95% and 99% of the areas under the normalcurve, the clinical coincidence rates in the preliminarily bending degrees of the titanium rod in the 30 patients were 80.00％，90.00％ and 96.67％, respectively.Conclusion The titanium rod that has been bent into a certain angle before operation according to the established criteria can definitely diminish its strain during operation and efficiently shorten the operating time．Thiskind of the titanium rod has a good coincidence in clinical application and can be effectively used in clinical practice.It is worth reference during the clinical operation.

Objective To understand the current status of the preferences and opinions on the investigator-initiated trails (IIT) of the neurosurgeons participating in INTERACT3 in China, as well as the design preference for IIT projects, and to provide a basis for the design and organization of multi-center clinical studies in the future. Methods Neurosurgeons with different seniority and professional titles from 89 domestic research institutions participating in the INTERACT3 project were collected from September to October 2023. The questionnaires were collected by questionnaire star. Results A total of 56 valid questionnaires were collected from 29 units. Among the 56 respondents, 52 neurosurgeons (92.86%) were from teaching hospitals and 45 (80.36%) were from grade A tertiary hospitals. 30 neurosurgeons (53.57%) had experience in conducting various clinical studies, and 55 neurosurgeons (98.21%) had experience in participating in various clinical studies. The main purposes of presiding over or participating in clinical research focused on “accumulating relevant experience and preparing for future projects” and “standardizing clinical diagnosis and treatment”, which were 89.29% and 83.93%. Respectively, regarding the way the case report form completing, respondents preferred to use electronic data collection systems (83.93%). Conclusions The purpose of the neurosurgeons interviewed to host or participate in clinical research is mainly to assist clinical and scientific research. Economic reasons have little impact on whether to participate in clinical research. The rationality and ease of operation of the trail design are the keys to attracting respondents to participate in clinical researches, and the level of remuneration has little impact on the decision-making of the respondents. The safety of clinical studies and the difficulty of enrolling subjects are the key factors that hinder respondents’ participation in clinical studies.
A team with strong cohesion and high execution is an important guarantee for conducting high-quality and sustainable clinical researches. Combined with the previous literature and the author’s view, this paper summarizes the key points of team building, which include a clear research direction, a balanced composition of team members, an outstanding team leader, the competence enhancement of team members, and a member-oriented management philosophy. Clear research direction is the premise of the existence and development of a team. Multi-level, multi-disciplinary membership can avoid potential conflicts of interest caused by homogeneity, and enable research to be refined and strengthened in interdisciplinary collisions. Team leader is the key to team development. The enhancement of team members’ competence is the cornerstone of team development. Adherence to member-oriented principle can form a true team culture. This paper aims to summarize and analyze the key points of clinical research team construction for peer reference.

Surgical innovation is an important part of surgical research and practice. The evaluation of surgical innovation through the stages is similar to those for drug development, but with important differences. The Idea, Development, Exploration, Assessment, and Long-term follow-up (IDEAL) Framework and Recommendations represent a new paradigm for the evaluation of surgical intervention and devices which was developed in 2009. The IDEAL is a five-stage framework involving the nature stages of surgical innovation, together with recommendations for surgical research pathway. The Framework and Recommendations were updated and published in 2019, which added a pre-IDEAL stage if necessary. The updated IDEAL also underlines the purpose, key question and ethical issues for each stage. In the first paper of IDEAL Framework and Recommendations series, we conducted a comprehensive introduction of IDEAL (e.g. the development, updates and application of IDEAL) to promote the dissemination and application of IDEAL in China.
Objective With reference to the method of operationalization of concept in the field of sociology, this study developed a methodological framework for intervention trials of Chinese medicine (CM) under the mode of syndrome dominating disease. Methods First, an operational definition of the syndrome dominating disease research model was clarified to provide the scope and direction of the methodological framework construction. Then a scoping review was conducted to identify the design features of clinical researches under the model to summarize the basic structure and content of the framework; furthermore, in-depth interviews were carried out to collect the views and suggestions of CM experts on this type of study, which added details to the framework. Finally, a survey was conducted to evaluate the rationality and feasibility of the methodological framework. Results A total of 74 studies were included and 12 CM experts were interviewed, and the results of the literature and interview study were synthesized to form a preliminary methodological framework. Thirty-two experts participated in the survey and most of them held a positive assessment of the rationality of the framework, then according to the experts’ suggestions, the final methodological framework which was a four-level structure with 25 items was established. Conclusion Following the internationally recognized methods and steps, this study develops a rational and feasible methodological framework for CM trials under the mode of syndrome dominating disease, which can provide references for future studies’ design, implementation and evaluation.
