RESUMEN
Objective:To retrospectively analyze the efficacy of video-assisted thoracoscopic surgery (VATS) in the treatment of solitary pulmonary nodule (SPN) and related factors affecting the diagnosis of benign and malignant SPN.Methods:The clinical data and surgical conditions of 317 patients with SPN who were resected by VATS and diagnosed by pathology in Chaoyang Central Hospital from January 2017 to December 2019 were retrospectively analyzed.The patient′s surgical efficacy and corresponding imaging features were explored.Results:Of the 317 patients, 124 (39.1%) cases underwent uniportal VATS and 193(60.9%) cases underwent multi-portal-portal VATS, 195(61.5%) cases had lobectomy, 16(5.1%) cases had anatomical segmentectomy, and 106(33.4%) cases had wedge resection. The operation time of the whole group was 50 - 210 (146.5 ± 34.7) min, intraoperative blood loss was 10 - 180 (69.3 ± 31.5) ml, thoracic drainage tube retention time was 2 - 7 (3.7 ± 1.4) d, postoperative hospital stay was 3 - 21 (6.4 ± 1.8) d, and the complication rate was 1.0%(3/317). No perioperative death occurred. Among all the nodules, 98(31.0%) cases were benign nodules and 219(69.1%) cases were malignant. Multivariate analysis showed that maximum nodule diameter, lobulated sign, burr sign, vascular bundle sign and pleural sag sign were independent related factors for the diagnosis of benign and malignant nodules ( P<0.05). Conclusions:VATS has less trauma and fewer complications, which has important clinical value for the diagnosis and treatment of benign and malignant SPN. Nodule maximum diameter, lobulated sign, burr sign, vascular bundle sign, pleural pit sign are independent related factors that affect the diagnosis of benign and malignant SPN.
RESUMEN
Objective To investigate the neurocognitive characteristics and related factors in the elderly with subjective cognitive decline. Methods Among the 1 850 elderly volunteers aged over 50,377 cognitive normal elderly (NC group),234 subjective cognitive decline ( SCD Group) and 291 patients with mild cognitive impairment (aMCI Group) were screened with the brief elderly cognitive screening question-naire and the elderly rapid cognitive screening scale. They were all received clinical interview and examina-tion and core neurocognitive test. Results ( 1) There were statistically significant differences in the three groups on the age,education,occupation,HAMD,low density lipoprotein and blood pressure (P<0. 01). (2) The score of the picture-symbol association in SCD group( 8. 94 ± 4. 05) was lower than that in NC group (9. 83±4. 18)and higher than that in aMCI group (7. 12±4. 17)(all P<0. 05),while the scores of the other neuropsychological tests were higher than those in aMCI group. There were no statistically significant differ-ence between SCD group and NC group on the other neuropsychological tests(P>0. 05). (3) The SCD was mainly influenced by age( β=0. 063, OR=1. 065,95% CI=1. 033-1. 099), depression ( β=0. 182,OR=1. 199,95%CI=1. 084-1. 327) and hypertension(β=0. 473,OR=1. 604,95% CI=1. 185-2. 171) ( all P<0. 01). And the aMCI was mainly influenced by age(β=0. 078,OR=1. 081,95%CI=1. 048-1. 115),educa-tion(β=-0. 174,OR=0. 840,95%CI=0. 778-0. 907),occupation( β=-0. 406,OR=0. 666,95%CI=0. 535-0. 830)and low density lipoprotein(β=-0. 451,OR=0. 637,95%CI=0. 497-0. 816)(all P<0. 01 ). Conclu-sion Objective neurocognitive function of the elderly with subjective cognitive decline is basically normal. Age,depression and hypertension are risk factors of subjective cognitive decline.
