RESUMO
@#Objective By applying the mutual corroboration in the diagnosis, we aimed to improve the accuracy of preoperative imaging diagnosis, select the appropriate timing of operation and guide the follow-up time for patients with pulmonary nodules. Methods Clinical data of 1 368 patients with pulmonary nodules undergoing surgical treatment in our department from July 2016 to October 2019 were summarized. There were 531 males and 837 females at age of 44 (21-67) years. The intraoperative findings, images and pathology were classified and analyzed. The imaging pathology and pathological changes of pulmonary nodules were shown as a dynamic process through mutual collaboration and interaction. Results Of 1 368 patients with pulmonary nodules, 376 (27.5%) were pure ground-glass nodules, 729 (53.3%) were mixed ground-glass nodules and 263 (19.2%) were solid nodules. Among the pure ground-glass nodules, adenocarcinoma in situ (AIS) accounted for the highest proportion (156 patients), followed by microinvasive adenocarcinoma (MIA, 90 patients), atypical adenomatous hyperplasia (AAH, 85 patients), and benign tumors (20 patients). Among mixed ground-glass nodules, 495 patients were invasive adenocarcinoma (IA) and 207 patients of MIA. no patient was featured by AAH, AIS or MIA. Conclusion The mutual collaboration and interaction can improve the accuracy of preoperative diagnosis of pulmonary nodules, and it supports the choice of operation timing and the judgment of follow-up time.
RESUMO
Objective:To investigate Th17,Treg and related factors before and after myocardial infarction ,and explore the cor-relations among them.Methods:Extracted mononuclear cell in peripheral blood ,and used fluorescence-activated cell sorting analysis to detect the contect of Th17 and Treg.Enzyme-linked immunosorbent assay was used to detect cytokine production of IL-17 and TGF-β;real-time PCR was used to detect the contect of RORγT and Foxp3.Results: Compared with the control group , experimental group (both before and after thrombolysis) had increased expressions of Th17,IL-17 and RORγT(P<0.05);the expressions of Treg,TGF-βand Foxp3 had decreased(P<0.05).Compared with the group of before thrombolysis ,the group of after thrombolysis 7 d had decreased expressions of Th17,IL-17 and RORγT(P<0.05);increased expressions of Treg,TGF-βand Foxp3(P<0.05).Conclusion:Compared with the control group,patients with myocardial infarction have the high levels of Th 17 and the related factors,the decreased levels of Treg and the related factors.Thrombolytic therapy can decrease the levels of Th 17 and the related factors,and increase levels of Treg and the related factors.
