Objective To explore the clinical application value of transcranial Doppler on patients with hyperlipidemia. Methods 80 patients with hyperlipemia and 70 healthy people were studied by transcranial Doppler ultrasound(TCD) of interal carotid artery hemodynamics. Results 57 (71.7%)of the 80 patients with hyperlipemia had arteriosclerosis, and terminal sclerosis happened on 12 patients ( 13.3% ). Compared with the control group, the difference was all statistically significant ( P ＜ 0.05 ). Conclusion Hemodynamics at the terminal of interal carotid artery patients with hyperlipemia was obvious abnormal studied by transcranial Doppler ultrasound (TCD) , and sclerosis of interal carotid artery is common complication of patients with hyperlipemia. Results showed that TCD could be used as a routine method for testing of patients with hyperlipemia and had some value in preventing cerebrovascular disease induced by hyperlipidemia.

Objective:To analyze the effect of thoracoscopic subsegmental resection under the guidance of three dimensional(3D)computed tomography bronchography and angiography(3D-CTBA)for resection of pulmonary nodules.Methods:A total of 40 patients who underwent 3D-CTBA-guided thoracoscopic subsegmental resection in Nanjing Jiangbei Hospital of Nantong University from January 2020 to October 2021 were selected as the observation group,and other 35 patients who underwent 3D-CTBA-guided thoracoscopic pulmonary segmentectomy were selected as the control group.The intraoperative and postoperative conditions,and the incidence of postoperative complications of the two groups were observed.Results:The differences of amount of intraoperative blood loss,average margin width,postoperative drainage,retention time of drainage tube between observation group and control group were significant(t=8.644,2.862,10.03,3.277,P<0.05),respectively.The numbers of occurring postoperative chest leakage,pulmonary infection and hemoptysis in observation group and control group were respectively"3,1,1"and"2,1,2".The incidences of complications of two groups were respectively 12.5%and 14.29%,without statistical significance between the two groups(P>0.05).Conclusion:3D-CTBA-guided thoracoscopic subsegmental resection can shorten the operation time,and reduce intraoperative blood loss and the injury of tracheas and blood vessels,and improve the postoperative recovery of patients.
