RESUMO
Objective To investigate the safety and efficacy of endoscopic thyroid surgery through axillary approach in the treatment of unilateral papillary thyroid carcinoma.Methods A total of 135 patients admitted to Yunnan Cancer Hospital from April 2022 to November 2022 were selected.According to the surgical method,69 patients were in the endoscopic group and 66 patients were in the open surgery group.The clinical data,operation time,intraoperative blood loss,postoperative drainage volume,postoperative hospitalization stay,complications,cosmetic satisfaction,scar evaluation,postoperative swallowing pain and blood calcium,blood phosphorus,PTH levels of the two groups were observed.Results There were no significant differences in general data,pathological features,number of lymph node dissection,and perioperative complications between the two groups(P>0.05).The operation time and postoperative drainage volume in the endoscopic group were significantly higher than those in the open surgery group.The intraoperative blood loss,postoperative hospital stay,pain score,serum calcium,serum phosphorus,PTH levels and cosmetic satisfaction in the endoscopic group were significantly better than those in the open group(P<0.05).Conclusion Transaxillary approach endoscopic thyroid surgery for the treatment of single-sided papillary thyroid carcinoma is safe,feasible,and provides better protection of the parathyroid glands,postoperative swallowing pain,and cosmetic satisfaction.
RESUMO
Objective@#To explore the effect of hematopoietic cytokines IL-11 on invasion and metastasis abilities of anaplastic thyroid cacinoma(ATC) cells.@*Methods@#Real-time PCR was performed for examining the IL-11 mRNA expression in thyroid carcinoma cell lines, and IL-11 protein expression in the supernament of thyroid carcinoma cell lines was detected by ELISA. Molecular cloning was employed to construct IL-11 stable knockdown cell line; MTT assay was used to analyze the effect of IL-11 on the proliferation of ATC cells; Transwell and wound healing assays were employed to analyze the abilities of migration and invasion in ATC cells. Western blotting was used to detect the relative pathway proteins. SPSS statistical package 19.0 was used to analyze the date, and Student′s t test was used for multiple comparisons.@*Results@#The protein level of IL-11 were significantly lower in knock-down cell lines than that in negative control cell lines(21.55±1.69, 16.18±0.85, 26.37±2.00 vs 54.54±3.99, all P<0.05). Colony formation assays reveal that colony number between knock-down cells and negative control cells has no significance(P>0.05). Meanwhile, MTT assays show that there is no significance between knock-down cell lines and negative control cell line(P>0.05). However, Transwell invasion and migration assays show that number of migrated cells is increased when ATC cells were treated with rhIL-11(0-100 ng/ml)at increasing concentrations.@*Conclusion@#IL-11 improves the migratory and invasive abilities of ATC cells via inducing EMT of ATC cells, and it can be used as a potential target for ATC molecular targeted therapy.
