Establishing and improving the quality control system of drug clinical trial institutions is the key to ensure the quality of clinical trial. In recent years, the number of drug clinical trial has been continuously improved, and the quality control requirements have been continuously improved. However, in clinical work, the workload of medical staff is heavy, and the energy devoted to clinical trial is limited. Clinical research coordinator (CRC), as a participant and coordinator of clinical trial, has carried out transactional work related to non-medical judgment under the authorization and guidance of researchers, and has undertaken any specific work in clinical trial. Based on the quality control management experience of nosocomial CRC and hospital drug clinical trial institutions in West China Hospital of Sichuan University, this paper discusses the mode of nosocomial CRC participating in clinical trial quality control. By participating in the quality control of clinical trial, the nosocomial CRC has improved the quality control efficiency, enriched the quality control team and improved the overall level of CRC. This model enriches the quality control system of drug clinical trial.
ObjectiveTo investigate the current situation of domestic registry studies, and to provide basis for future research.MethodsWorld Health Organization (WHO) registration platform, ClinicalTrials.gov registration platform and other registration platforms were searched to collect the registered registration studies in Mainland China from inception to July 31st, 2018. Two researchers collected and collated data, analyzed by descriptive statistical methods, and then python-igraph package in Python 3.5 was used to draw the network diagram.ResultsA total of 247 studies were retrieved, mainly for disease registry and pharmaceutical product registry. Cohort and case-series were the principally study design. The research focused on chronic diseases such as cardiovascular and cerebrovascular diseases, and research sites were based on the economically developed area, for example, Beijing, Shanghai and Guangdong. The network diagram of study design and disease system shows that cohort research design is widely used in the nervous system and circulatory system; the network diagram of the research sites and disease system found that Beijing mainly studied circulatory and nervous system diseases, Shanghai mainly studied circulatory system diseases, and Guangdong relatively studied more on nervous system and urinary system diseases.ConclusionThe increasing number of registry studies in China reflects the importance of long-term outcome assessment of diseases.
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.

Ethical issues in clinical research are receiving increasing attention. The application of research projects, the registration of clinical trials and the publication of scientific researches have always been involved with ethical issues. This paper elaborates ethical development and changes in Chinese clinical research from the aspects of the development of medical ethics, the establishment of ethics laws and regulations, international certification of medical ethics committee, the advantages, challenges, opportunities and innovation and development of TCM clinical research ethics as well as the certification system of TCM research ethics.
Telephone follow-up is one of the important ways to follow up patients. High-quality follow-up can benefit both doctors and patients. However, clinical research-related follow-up is often faced with problems such as time-consuming, laborious and poor patient compliance. The authors belong to a team that has been committed to the study of patient-reported outcomes for a long time. The team has carried out long-term follow-up of symptoms, daily function and postoperative complications of more than 1 000 patients after lung cancer surgery, and accumulated certain experience. In this paper, the experience of telephone follow-up was summarized and discussed with relevant literatures from the aspects of clarifying the purpose of clinical research follow-up, understanding the needs of patients in follow-up, and using follow-up skills.
In recent years, clinical research shows the trend of globalization. Due to characteristics of the huge number and relative concentration of patients, the wide variety of diseases, a high patient enrolment rate, lower trials costs, and so on, China and India become a focus of this trend. However, China and India also have their own advantages in the aspects of diseases, infrastructure, policies, regulations, regulatory environment, language, and culture. The key question to address is: how to increase the shares in the trial market in the future and to enhance the international status of China’s clinical research? Before we answer this question, we must understand the present situations of clinical research resources in China and India. So, we searched the relevant literature at home and abroad by computer and hand to analyze advantages and efficiency of clinical research resources in China and India.

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.
Evidence-based research in traditional Chinese medicine (TCM) has made many important achievements and promoted the modernization and internationalization of TCM. The ability to produce research evidence to guide clinical practice in an emergency treatment situation is a major test of the development of evidence-based Chinese medicine (EBCM) when emerging infectious diseases outbreaks. Along with the development of EBCM, TCM has experienced emerging infectious disease events such as atypical pneumonia (SARS), influenza A (HIN1), and corona virus disease 2019 (COVID-19), and the ability of TCM to conduct clinical research in emergency treatment work has been continuously improved. This article provides an overview of the clinical research conducted in TCM to resist emerging infectious diseases in the past, focusing on the clinical research results obtained in the present time of COVID-19 rescue and treatment, and discusses the role of EBCM development to enhance the clinical research capacity of TCM in emerging infectious diseases.
