Clinically,the surgical treatment of varicose veins of the lower extremities(VVLE)is now developing towards the direction of precision,minimally-invasive and individuation.Thus,comprehensive preoperative examination and evaluation of the venous system,and scientific marking of the target veins are prerequisite for achieving these goals.This paper describes the latest research progress in VVLE,focusing on the pathophysiology,risk factors,etiology,evaluation method of venous system,preoperative evaluation of commonly-seen secondary etiology,selection of surgical method,and marking technique of targeted veins,etc.So as to promote the development of surgical treatment for VVLE in clinical practice.

Objective To assess the correlation between the severity of postoperative nausea and vomiting(PONV)with the quality of postoperative recovery and capacity of mobility in patients after video-assisted thoracoscopic surgery.Methods A total of 125 patients,80 males and 45 females,aged 18-64 years,BMI 18-35 kg/m2,ASA physical status Ⅰ-Ⅲ,undergoing video-assisted thoracoscopic surgery were observed.The severity of PONV was assessed using the simplified PONV impact scale day 1 after sur-gery.The patients were divided into three groups according to the severity of PONV:non-PONV group(n = 87),mild PONV group(n = 31),and moderate to severe PONV group(n = 7).The quality of recovery was assessed using the quality of recovery-15(QoR-15)on the first day after surgery,and the capacity of mobility was assessed using the 6-minute walk test(6-MWT)on the second day after surgery.The multiple linear regression model was used to analyze the correlation between the severity of PONV and quality of post-operative recovery and capacity of mobility.Results The results of the corrected multiple linear regression model showed that,compared with the patients without PONV,the QoR-15 scores of the patients with mild and moderate-severe PONV on the first day after surgery were reduced by 4.5 scores(95%CI-8.9 to-0.04 scores,P = 0.048)and 15.8 scores(95%CI-24.8 to-6.8 scores,P = 0.001),respectively.Mild(MD =-27.4 m,95%CI-70.1 to 15.4 m,P = 0.207)and moderate-severe PONV(MD =-57.0 m,95%CI-145.7 to 31.6 m,P = 0.204)were not significantly associated with 6-MWT distance shortening on the second day after surgery.Conclusion Increased PONV severity is associated with poorer recovery quality in patients undergoing pulmonary surgery.Active prevention and treatment of PONV may contribute to early recovery of patients.

Objective:To investigate the application value of early and late interventional embolization in intracranial aneurysms.Methods:Eighty-two patients with intracranial aneurysm who received treatment in Wenzhou People's Hospital from October 2015 to February 2020 were included in this study. These patients were divided into early (≤ 3 days) and late (> 3 days) groups, with 41 patients in each group, according to time from disease onset to surgery. The early group was subjected to early interventional embolization, and the late group was treated with late interventional embolization. The effects of embolization and National Institutes of Health Stroke Scale score pre- and post-treatment, as well as modified Barthel index, Mini-Mental State Exam score, matrix metalloproteinase-9 level, and soluble intercellular adhesion molecule-1 level post-treatment and prognosis were compared between the two groups.Results:The embolization effects in the early group were statistically superior to those in the late group ( P = 0.046). After treatment, National Institutes of Health Stroke Scale score in the early group was significantly lower than that in the late group [(4.02 ± 1.64) points vs. (6.81 ± 2.02) points, t = 6.86, P < 0.01]. Mini-Mental State Exam score and modified Barthel index in the early group were (28.09 ± 1.35) points and (81.12 ± 9.67) points, respectively, which were significantly higher than (26.01 ± 1.19) points and (73.02 ± 8.19) points in the late group ( t = 7.40, 4.09, both P < 0.001). After treatment, matrix metalloproteinase-9 and soluble intercellular adhesion molecule-1 levels in the early group were (420.33 ± 29.40) μg/L and (403.70 ± 23.28) ug/L, respectively, which were significantly lower than (491.30 ± 31.19) μg/mL and (496.37 ± 30.46) μg/L in the late group ( t = 10.60, 15.47, both P < 0.001). Prognosis in the early group was superior to that in the late group ( P = 0.049). Conclusion:Early interventional embolization has better efficacy than late interventional embolization in the treatment of intracranial aneurysm. The former can effectively improve neurological function and mental state, enhance living ability, and improve prognosis, which may be related to the regulation of matrix metalloproteinase-9 and soluble intercellular adhesion molecule-1 levels.

Cancer-associated fibroblasts (CAFs) are essential parts of tumor stroma. Fibroblast activation protein (FAP), overexpressed in CAFs, is closely related to tumor growth, invasion, metastasis, immunosuppression and prognosis, which is a vital target for tumor targeted diagnosis and therapy. In recent years, a variety of new radiolabeled quinoline-based FAP inhibitors (FAPIs) have been used for tumor targeted diagnostic and therapeutic research. A number of studies have confirmed that radiolabeled FAPIs plays an important role in tumor diagnosis, staging and treatment, which have a good clinical application prospect. This review summarizes the research status of radiolabeled FAPIs and discusses their potential in the accurate diagnosis and therapy of tumors.
