ABSTRACT
ObjectiveThe aim of this study was to evaluate and compare the surgical outcomes of endoscop ic and conventional open thyroidectomies in patients with thyroid disease.Methods116 patients with tyroid tumor were enrolled.56 patients underwent endoscopic thyroidectomy ( endoscopic group ),and 60 patients underwent conventional open thyroidectomy( conventional group).We analyzed the patients' clinic characteristics,surgical outcomes and complications between the two groups.ResultsThe blood loss was less in the endoscopic group than the open group[( 16.8 ± 9.6) ml vs ( 24.9 ± 14.2 ) ml,t =- 2.427,P ＜ 0.05].The degree of satisfaction for cosmetic outcome in endoscopy group( 96.4％ ) was higher than that in conventional group ( 16.7％ ) ( x2 =74.508,P ＜ 0.01 ).There was no significant difference in the operating time,volume of drainage and postoperative hospital stay between two groups,and there was no significant difference in the skin ecchymosis,redness and swelling and postoperative pain between two groups( all P ＞ 0.05).No severe postoperative complication was encountered,such as injuries of the re current or superior laryngeal nerve,parathyroid gland injury or massive hemorrhage.ConclusionEndoscopic thyroidectomy has less blood loss,mini-open and excellent cosmetic benefits compared with conventional open thyroidectomy.
ABSTRACT
Objective To look for a better way to assay vascular endothelial growth factor(VEGF) and explore the correlation of serum VEGF levels with platelet and leucocyte count in breast cancer by comparison of peripheral blood plasma, serum and P-APR. Methods Blood samples were obtained from 42 patients with breast cancer and 20 healthy volunteers. Serum, plasma and P-APR samples were analyzed for VEGF using a commercially available sandwich ELISA, and assayed for semiquantitative measurement using microplatereader. At the same time, samples were analyzed by hematology analyzer. Results The level of VEGF in peripheral blood positively correlated to platelet (health control group: r=0.424, P=0.063) and leucocyte (health control group: r=0.443, P=0.050). The difference in VEGF values of P-APR between the localized breast cancer group and the health control group was statistically significant. Conclusion The level of VEGF in peripheral blood positively correlates to platelet and leucocyte. Platelet and leucocyte possibly secrete VEGF in vitro. Compared with serum and plasma, P-APR is the best section assaying VEGF in peripheral blood.
