Objective To discuss the relationship between thyroid stimulating hormone (TSH) and clinicopathologic features of the papillary thyroid microcarcinoma (PTMC) patients. Methods The thyroid nodules of 806 cases retrospectively that were for the first time hospitalized to our department in recent 5 years were collected, among them, postoperative pathological examination confirmed the diagnosis of PTMC in 403 cases, 403 cases of benign thyroid lesions, the history data of selected cases that meet the criterion of selection were retrospectively analyzed. TSH and anti thyroid globulin antibody (TGAb) levels between the 2 groups and the prevalence of ratio of PTMC in different TSH levels were compared. Univariate and multivariate analysis were performed to determine the risk factors of PTMC. Results The differences of preoperative TSH levels between the two groups was statistical significance (Z=–6.233,P=0.001), gender composition no statistical significance in two groups (χ2=3.246,P=0.072), and age was statistically significant (Z=–5.855,P=0.001). The constitution of ethnics of two groups was different (χ2=38.961,P=0.001). Logistic regression analysis display that age and TSH level were the independent risk factors of PTMC (age:OR=0.914,P=0.027; TSH:OR=4.662,P=0.008). Conclusions The level of serum TSH in PTMC patients is higher than in patients with benign thyroid nodules. TSH level is probably predictive of malignancy of PTMC.
Objective To discusses the feasibilities of the hybrid surgical treatment of Stanford type B aortic dissection. Methods From August 2011 to August 2015 a total of 14 cases of complex Stanford type B aortic dissection patients had been completed hybrid surgery. Among them 11 cases of men and 3 cases of women, aged 22 to 62, an average of 44±7.2 years old. Twelve cases with dissecting aneurysm involving the aortic arch and its three vascular branch. There were 2 cases of patients after TEVER, occurred new dissection or pseudoaneurysms, and had hybrid surgery by traditional thoracotomy; 3 cases involving carotid artery were received neck-neck hybrid surgery, and 7 cases involving left subclavian artery were received neck-lock hybrid surgery. Two cases of dissecting aneurysm involving the iliac artery to thrombosis that result in lower limb ischemia, then femoral to femoral artery hybrid surgery were performed. Results All the patients were successfully completed the operation of covered stent implantation and hybrid surgery. Intraoperative angiography showed that the position of the stent was accurate, the interlayer isolation was successful, there was no obvious leakage and displacement of the stent, the true lumen blood flow of the aortic dissection was returned to normal, and bypass blood and target blood vessels were unobstructed. Fourteen patients were followed-up for a period of 3 to 36 months, with an average of (24.0±8.2) months. In 1 month after operation, pleural effusion occurred in 1 case, there was 1 case of cerebral stroke in two days after surgery, incision hematoma occurred in 1 case in 10 days after surgery, and the other patients had no postoperative death and severe complications. All 14 patients were followed-up and returned to normal life. Conclusion The hybrid operations can increase the success rate of TEVAR in complex Stanford type B aortic dissection patients, and early and mid-term results are satisfactory.
