Objective To explore the application of video-assisted thoracic surgery (VATS) in the diagnosis and treatment of mediastinal tumors. Methods Thirty-four patients with mediastinal tumors underwent VATS from June 1995 to December 2002. The patients comprised 9 men and 25 women, with a mean age 43 9 years (16～74 years). Entered into the study there were 14 cases of thymoma (9 benign thymomas and 5 malignant), 6 cases of neurogenic benign tumors, 5 bronchogenic cysts, 4 teratomas, 2 pericardial cysts and 3 other conditions (metastatic carcinoma, lymphoma and hemangioma racemosum, respectively). Maximum diameter of the tumors ranged 3 5 cm to 6 cm, mean 4 5 cm. Operations were performed under general anesthesia, double lumen endotracheal tube placement and single lung ventilation. The patients were maintained in the lateral decubitus position. Camera port was placed at the sixth or the seventh intercostals space on the midaxillary line. Sites of the other two ports depended upon the location of the tumors. Results Out of the 34 patients with mediastinal tumors, 25 patients underwent tumor removal by VATS alone and 6 patients received VATS combined with mini-thoracotomy, while the remaining 3 patients only underwent biopsy by VATS. Postoperatively, all patients recovered uneventfully, without severe complications or mortality. Conclusions VATS is the first choice for benign mediastinal tumors, typically those in the middle and posterior mediastinum.

Objective To explore the association of Lipoprotein-associated phospholipase A2(LP-PLA2) and Antithrombin Ⅲ(AT-Ⅲ)level with the severity of coronary artery lesion in patients with coronary disease. Methods 276 patients undergoing coronary angiography were recruited in the Affiliated Hospital of Xuzhou Medical University from March,2016 to March,2017. Patients were sent to one of the two following groups according to their CAG reports:the controlled group(n=111)and the CAD group(n=165). Gensini scores were calculated in CAD group,and divided CAD group into 4 groups by quartiles:group 1(n=41),group 2(n=39),group 3 (n=42)and group 4(n=43). LP-PLA2 and AT-Ⅲwere then compared in different groups and correlation was analyzed in deciding the severity of coronary artery disease. Results (1)LP-PLA2 level in CAD group was signifi-cantly higher than the controlled group(342.9 ± 91.9 vs. 131.8 ± 27.0,P<0.05),but AT-Ⅲlevel was lower than controlled group and(91.0 ± 12.9 vs. 97.8 ± 11.0,P<0.05).(2)Both LP-PLA2 and AT-Ⅲlevel were different in groups stratified by the quartiles of Gensini scores,and the difference is statistically significant.(3)LP-PLA2 was a risk factor while AT-Ⅲwas a protectional factor for coronary artery disease(OR=1.08,95%CI:1.05~1.11,P<0.01;OR=0.95,95%CI:0.93~0.98,P<0.01;respectively )analyzed by Logisitic regression model.(4)Correla-tion analysis showed a positive association of LP-PLA2 level with Gensini scores(r=0.48,P<0.01),and a nega-tive association of AT-Ⅲlevel with Gensini scores(r=-0.24,P<0.01). Conclusion LP-PLA2 level was higher in CAD patients compared to normal patients ,while the relationship of AT-Ⅲ level among the two groups was reversed. Elevated LP-PLA2 level was associated with the increased severity of coronary artery and can provide guidance for clinic.
