Mitochondrial quality control includes mechanisms such as mitochondria-derived vesicles, fusion / fission and autophagy. These processes rely on the collaboration of a variety of key proteins in the inner and outer membranes of mitochondria to jointly regulate the morphological structure and functional integrity of mitochondria, repair mitochondrial damage, and maintain the homeostasis of their internal environment. The imbalance of mitochondrial quality control is associated with leukemia. Therefore, by exploring the mechanisms related to mitochondrial quality control of various leukemia cells and their interactions with immune cells and immune microenvironment, this article sought possible targets in the treatment of leukemia, providing new ideas for the immunotherapy of leukemia.

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.

Objective To explore the value of applying intelligent quality control systems to the quality management of hospital health examination services, and to provide a reference for quality control improvement in the health examination industry. Methods The Department of Health Management Center of Zigong Fourth People’s Hospital used an intelligent quality control system to optimize the health management service process. The work efficiency and feedback of health examinations in the Department of Health Management Center before (From October to December 2019) and after (From October to December 2023) the intelligent upgrade of the health management service system were compared. Results During the research period, 27047 individuals were tested before the intelligent upgrade, and 33868 individuals were tested after the upgrade. Before the intelligent upgrade, there were 205 cases (14.24%) of errors that the system failed to detect; 208 cases (8.72%) were missed in the initial examination system; 18 cases (13.53%) were missed in the overall examination system; 90 cases (0.33%) had overdue physical examination reports. After the intelligent upgrade, there were 38 cases (2.42%) of errors that the system failed to detect; 56 cases (1.93%) were missed in the initial examination system; 10 cases (3.31%) were missed in the overall examination system; 67 cases (0.20%) had overdue physical examination reports. After the intelligent upgrade, the system showed better performance than before in detecting errors in health examinations, avoiding initial and total leak diagnosis, timely report submission, and improving the satisfaction and complaint situation of health management services among examinees (P<0.05). Conclusion The intelligent quality control system is conducive to improving the quality management of hospital health examination services and enhancing the efficiency of examination services.

Objective To monitor surgical quality and analyze learning curve of minimally invasive totally thoracoscopic cardiac surgery. Methods We retrospectively analyzed the clinical data of 150 consecutive patients who underwent minimally invasive totally thoracoscopic cardiac surgery in the Guangdong General Hospital between January 2013 and December 2015. There were 60 males and 90 females at age of 43.1 years. There were 60 patients with atrial or ventricular septal defect repair, 12 patients with cardiac tumor resection, 53 patients with mitral valve replacement and 25 patients with mitral valve repair. According to the surgical sequence, all the patients were divided into 3 groups including a group A, group B, and group C with 50 patients in each group (every 10 patients as a sequence, every 5 sequence as a group). Surgical outcomes were compared among the 3 groups, and surgical quality was analyzed with descriptive statistics. Results Surgical failure rate was 6.7% (10/150). There was no in-hospital mortality. Aortic cross-clamp time, cardiopulmonary bypass time and duration of mechanical ventilation, duration of ICU stay, duration of hospital stays of the group C were significantly shorter than those of the group A and group B. Analysis showed a significant learning curve effect in totally thoracoscopic cardiac surgery. When surgical cases reached about 100 cases, cardiopulmonary bypass and aortic cross-clamp time was shorter than the average value stably. Conclusion Totally thoracoscopic cardiac surgery is safe and reliable. For the beginners, it needs about 100 patients of surgery to master the totally thoracoscopic cardiac surgery.
