Objective To investigate the changes of CD11b on neutrophils during myocardial ischemia-reperfusion injury. Methods 12 patients undergoing coronary bypass grafts under CPB were studied. Blood samples were obtained from the coronary (coronary sinus) and systemic circulation (central venous and CPB machine), respectively. Samples obtained from coronary and systemic circulation were taken before the beginning of CPB, during CPB and after cardiac reperfusion. Neutrophil CD11b expression and serum cTnI concentration were measured. Results (1)Expression of CD11b increased gradually in systemic circulation during CPB and after reperfusion (P

OBJECTIVE: To determine serum levels of betatrophin in patients with polycystic ovary syndrome (PCOS) and the influential factors. 
 METHODS: A total of 100 PCOS patients were enrolled randomly as a PCOS group, and 40 age-matched healthy women were recruited as a normal control (NC) group. Primary clinical or biochemical parameters of the subjects were detected. The results were analyzed by SPSS 19.0.
 RESULTS: Serum betatrophin levels were elevated in the PCOS group compared with the NC group. Serum betatrophin levels were positively correlated with age and Whole Body Insulin Sensitivity Index (WBISI),and negatively correlated with body mass index, fasting insulin(FINS), homeostatic model assessment insulin resistance (HOMA-IR) and homeostatic model assessment β cell function (HOMA-β). Multiple linear stepwise regression analysis showed that age and waist hip ratio (WHR) were independent influential factors for the level of betatrophin. PCOS was more likely to occur in women with higher betatrophin levels.
 CONCLUSION Serum betatrophin levels increase in women with PCOS and they are independently associated with age and WHR. There is no significant correlation between betatrophin and insulin resistance or insulin levels.

National Comprehensive Cancer Network (NCCN) has updated and released the latest content of NCCN guidelines version 1. 2023 thymomas and thymic carcinomas (known as "guidelines"). The guideline sets standards for the diagnosis and treatment of thymoma and thymic carcinoma based on high quality clinical evidence and the latest advances in research. There have been some updates and revisions in the latest two versions of the guidelines, mainly focusing on the principles of radiotherapy, the principles of systematic therapy, multidisciplinary participation and the improvement of some footnotes, compared with the first version of the guidelines in 2022. In this paper, the contents of the new guideline will be interpreted in order to provide reference for the work of thymoma and thymic carcinoma in our country at the present stage.

Surgery is an important treatment for the anterior mediastinal disease. With the rapid development of minimally invasive techniques, complete resection of the lesion in most patients with thymic disease can be achieved through thoracoscopic surgery. Practice has proved that the three-port resection of anterior mediastinal thymus disease via the subxiphoid approach is an ideal surgical method for the treatment of anterior mediastinal thymic tumors at present, which has strong popularization and popularity and can benefit the patients. The procedure focuses primarily on the anterior and upper mediastinum and can thoroughly expose the anatomy of the mediastinum and both sides, with minimal intraoperative bleeding, high safety, minimal trauma and postoperative pain, and a short hospital stay. It has clear advantages over conventional thoracic open-heart surgery and transversal resection. However, the surgical approach and field of view, and intraoperative precautions of this procedure are completely different from those of previous thoracoscopic procedures, and from the subxiphoid single-port approach adopted by other centers. Based on 10 years of surgical experience at our center, a modular mode of surgical operation has been developed and its procedure has been standardized. This paper will share and discuss relevant operational points and experiences.
