Objective: To compare the in vitro quality differences of leukoreduced pooled concentrated platelets prepared from whole blood preserved at different temperatures and for various durations, determine the safe time window for refrigerated whole blood in platelet preparation, and provide experimental evidence for optimizing blood component preparation procedures and improving the comprehensive utilization rate of blood resources. Methods: A total of 324 units of 400 mL ACD-B anticoagulated whole blood were randomly divided into two groups and stored at 4℃ and 22℃, respectively. The buffy coat was separated at three time intervals: <6 h, 6-12 h, and >12 h (≤18 h) post-collection, and allowed to rest overnight at 22℃. On the following day, the buffy coats from each group were pooled to prepare leukoreduced pooled platelet concentrates (LPPCs). Cell counts were performed, and metabolic parameters including pH, glucose, and lactate levels were measured to evaluate metabolic status. Platelet in vitro function and activation were assessed by thromboelastography (TEG), platelet aggregation rate, and the expression of PAC-1 and CD62P. The differences between the two groups were compared. Results: For pooled concentrated platelets prepared from whole blood stored at 4℃ and 22℃ for <6 h and 6-12 h, there were no significant differences in platelet count, pH, glucose levels, lactic acid levels, thromboelastography (TEG), platelet aggregation rate, or platelet activation rate (P>0.05). With prolonged refrigeration time of whole blood, compared with pooled concentrated platelets prepared from whole blood stored at 22℃ for >12 h but ≤18 h, those prepared from whole blood stored at 4℃ for >12 h but ≤18 h showed a decreased platelet count (1 152.83±180.08 vs 1 368.83±134.86, P=0.040), a significantly increased ADP-induced aggregation rate (26.82±6.59 vs 13.88±10.21, P=0.030), and significantly elevated expression rates of PAC-1 and CD62P (72.64±6.74 vs 63.28±5.97, P=0.030). However, there were no significant differences in pH, glucose content, lactate content, or thromboelastography (P>0.05). Conclusion: There was no significant difference in the in vitro count, function, or activation of pooled concentrated platelets prepared from whole blood stored at 4℃ and 22℃ within 12 hours. However, statistically significant differences were observed between the mixed concentrated platelets prepared from whole blood stored at 4℃ and those stored at 22℃ for more than 12 hours but not exceeding 18 hours. These findings can provide a reference for the preparation methods and clinical application of refrigerated platelets.

To assess the current status of early surgical site infections following prosthetic implantation in plastic surgery across four provincial-level administrative regions in China, and to explore the effectiveness of standardized training for infection prevention and control.

In 2022, general president Xi Jinping pointed out that "high-quality development is the top task of building China into a modern socialist country in all respects" at the 20th National Congress of the Communist Party of China. Since then, various industries have embraced the trend of high-quality development. This article aims to provide a specific reference point for the high-quality development of the plastic and aesthetic industry, based on the understanding of national policy documents and combined with the current situation and characteristics of the plastic and aesthetic specialty.

Medical quality and safety are essential safeguards for the harmonious society in China, directly affecting people's sense of security and happiness. Continuously improving medical quality and ensuring medical safety are fundamental and essential to implementing the strategies of the Party Central Committee and the State Council, and promoting the construction of a healthy China. In recent years, with the rapid development of China's economy and the people's increasing emphasis on their own health and safety, China's plastic surgery industry has achieved significant progress and yielded outstanding results. However, along with the rapid growth of the industry, medical quality issues and safety accidents have occurred frequently, attracting widespread attention from all sectors of society. This article briefly outlines the history of quality management and quality control for medical quality and safety in China's plastic surgery specialty. It explores the development of quality management from its origin to medical quality management, as well as the responsibilities and contributions of the National Plastic Surgery Quality Control Center in improving industry standards and ensuring patient safety. It aims to provide support for the standardized management of the plastic surgery industry in the future, so as to promote its healthy and sustainable development.

Objective To investigate the feasibility of leucocyte-reduced pooled platelet concentrates from whole blood stored at 4℃,and provide theoretical basis for the components preparation.Methods The collected 400 mL ACD-B antico-agulant whole blood was randomly divided into two groups,stored at 4℃and room temperature.The buffy coat was prepared within 6 hours and store at 22℃until next day to prepare leucocyte-reduced pooled platelet concentrates.Platelet samples on day 1,3,5 and 7 were taken for the blood cell count and related parameter detection.The pH,glucose and lactic acid con-tent were determined to reflect the metabolic status,and the thromboelastography,platelet aggregation rate and PAC-1 and CD62P expression were determined to reflect the function and activation of platelets.The difference in platelets between two groups were analyzed.Results With the extension of storage time,the count of leucocyte-reduced pooled platelet concen-trates decreased gradually,but the platelets distribution width(PDW),mean platelet volume(MPV)and platelet-larger cell ratio(P-LCR)increased gradually in two groups,with no statistical significance(P＞0.05).The pH and glucose con-tents in two groups gradually decreased,but the lactic acid content gradually increased,with no significant difference(P＞0.05).The thrombelastogram showed MA value that reflecting platelet function has no significant change during the storage,and there was no significant difference between the two groups(P＞0.05).The aggregation rates decreased while the expres-sion of PAC-1 and CD62P increased gradually with the prolongation of preservation time,with no significant difference be-tween the two groups(P＞0.05).Conclusion There is no significant difference in platelet count,function and activation between whole blood stored at 4℃and at room temperature within 6 hours.Whole blood stored at 4℃within 6 hours can be considered as the raw material for leucocyte-reduced pooled platelet concentrates.
