ObjectiveTo investigate the effects of intraoperative intermittent pneumatic compression (IPC) treatment on coagulation and fibrinolysis, lower extremity venous blood flow velocity, and deep venous thrombosis (DVT) in patients with gastric cancer (GC) after radical gastrectomy. MethodsThe patients with GC who underwent radical gastrectomy at Hebei Provincial People’s Hospital from July 2021 to July 2024 were retrospectively enrolled, then the patients were assigned into control group (the patients who did not receive intraoperative IPC) and study group (the patients who received intraoperative IPC), and the propensity score matching (PSM) method was used to conduct 1∶1 matching based on the basic characteristics such as age, gender, body mass index, comorbidities to ensure baseline comparability between the two groups. The incidences of postoperative DVT and lower extremity swelling, and coagulations [prothrombin time (PT), thrombin time (TT), activated partial thromboplastin time (APTT)] and fibrinolysis [D-dimer (D-D), fibrinogen (FIB), and fibrin degradation products (FDP)], as well as lower extremity venous blood flow velocity were analyzed after PSM. The locally weighted regression was used to analyze the correlation between the coagulation and fibrinolytic functions indexes and the lower extremity venous blood flow velocity. ResultsA total of 120 patients were matched (60 cases per group). The baseline characteristics of both groups were comparable (P>0.05). The incidences of DVT on day 7 and lower extremity swelling on day 1, 3, and 7 after surgery in the study group were significantly lower than those in the control group (P<0.05). The results of repeated-measures analysis of variance showed that there were statistically significant differences in the inter-group, time-related, and group-by-time interaction effects of coagulation and fibrinolysis indexes as well as lower extrimety venous blood flow velocities (P<0.05). The impact of the time factor on coagulation and fibrinolysis indexes and lower extrimety venous blood flow velocities varied with intraoperative IPC intervention measures. After surgery, the PT, TT, APTT, and lower extrimety venous blood flow velocities in the study group first decreased and then increased as compared with those before surgery, and the decrease degree was smaller and the increase degree was larger than those in the control group. After surgery, the D-D, FIB, and FDP in the study group first increased and then decreased as compared with those before surgery, and the increase degree was smaller and the decrease degree was larger than those in the control group. Both PT and TT were significantly positively correlated with femoral vein blood flow velocity (r=0.21, P=0.042; r=0.22, P=0.040), and both also showed significant positive correlations with popliteal vein blood flow velocity (r=0.25, P＜0.001; r=0.20, P=0.032). APTT was only significantly positively correlated with popliteal vein blood flow velocity (r=0.33, P＜0.001). D-D was negatively correlated with the flow velocities of the femoral vein, external iliac vein, and popliteal vein (r=–0.23, P=0.012; r=–0.22, P=0.047; r=–0.37, P<0.001). Both FIB and FDP were negatively correlated with the flow velocity of the femoral vein (r=–0.23, P=0.036; r=–0.27, P=0.002). FIB was also negatively correlated with the flow velocity of the popliteal vein (r=–0.26, P=0.038), and FDP was negatively correlated with the flow velocity of the external iliac vein (r=–0.31, P<0.001). ConclusionBased on the results of this study, intraoperative IPC treatment could improve coagulation and fibrinolytic functions of patients with GC after surgery, and has a certain preventive effect on occurrence DVT of lower extremity.

Candida auris is an emerging multidrug-resistant fungus that has become a significant global public health threat due to its strong resistance to antifungal agents and its ability to spread within healthcare facilities. This paper reviews the global epidemiological trends of Candida auris and the current status of existing prevention and control systems, focusing specifically on pathogen epidemiological characteristics, domestic and international epidemic situations, current prevention and control frameworks, and the construction of prevention networks. In response to the challenges posed by the international spread of Candida auris , China’s fungal disease prevention system should advance towards a more systematic and scientific direction. By integrating resources from medical institutions, disease control agencies, and research institutes, and combining multidisciplinary knowledge and technologies, China should establish a multi-level coordinated prevention and control mechanism to improve its monitoring, prevention, and treatment systems. In the future, China’s fungal disease prevention and control system needs to further strengthen talent cultivation, improve surveillance networks, promote technological innovation, and build a comprehensive, multi-level modern prevention and control system.
How to accurately identify factors of cancer occurrence and to provide intervention early are the key issues that urgently need to be addressed in cancer prevention and treatment. Mendelian randomization (MR) analysis uses genetic variants as instrument variables for exposures of interest, which compensates the shortcomings of traditional observational studies and clinical trials. This review introduced the current application status of MR analysis in cancer etiology and treatment researches in details, including assessment of cancer risk factors, exploration of cancer treatment targets, and evaluation of drug efficiency and adverse reactions. The scopes and dimensions of cancer etiology and treatment researches are greatly expanded because of various MR designs and abundant high-level omics data. As well, it provides a practical and feasible method for constructing cancer etiology networks and drug targeted databases, which are promising for supporting the development of precision cancer prevention and treatment.
