RESUMO
Objective:To investigate the relationship between parathyroid hormone（PTH） level and permanent hypoparathyroidism（PHPP） on the first day after radical papillary thyroidectomy, and its predictive value. Methods:A total of 80 patients with papillary thyroid cancer who underwent total thyroid resection and central lymph node dissection were collected and analyzed from January 2021 to January 2022. According to whether PHPP occurred after surgery, the patients were divided into hypoparathyroidism group and normal parathyroid function group, and univariate and binary logistics regression were used to analyze the correlation between PTH and serum calcium levels and PHPP on the first day after surgery in two groups. The dynamic changes of PTH at different time points after operation were analyzed. The area under the receiver operating characteristic was used to evaluate the predictive power of PTH on the development of PHPP after surgery. Results:Among the 80 patients with papillary thyroid cancer, 10 cases developed PHPP, with an incidence rate of 12.5%. Binary logistics regression analysis showed that PTH on the first postoperative day（OR=14.534, 95%CI: 2.377-88.858, P=0.004） was an independent predictive risk factor for postoperative PHPP. Taking PTH=8.75 ng/L on the first postoperative day as the cut-off value, the AUC of the area under the curve was 0.874（95%CI: 0.790-0.958, P<0.001）, the sensitivity was 71.4%, the specificity was 100%, and the Yoden index was 0.714. Conclusion:PTH level on the first day after total thyroid papillary carcinoma surgery is closely related to PHPP, and is an independent predictor of PHPP.

Objective To find the potential risk factors for pancreatic fistula after distal pancreatectomy.Methods Clinical data of 125 cases of consecutive distal pancreatectomy in Ningbo Lihuili Hospital from January 2006 to June 2013 were retrospectively analyzed.Results In all the 125 patients with distal pancreatectomy,pancreatic fistula was the most common surgical complication (43/125,34.4％),including 27 cases of grade A fistula,16 cases of grade B pancreatic fistula.Multivariate analysis showed that the texture of the pancreas and main pancreatic duct ligation were the independent risk factors for pancreatic fistula (all P ＜ 0.05).Conclusions Pancreatic fistula was the most common surgical complication of distal pancreatectomy.The texture of the pancreas and main pancreatic duct ligation effect the occurrence of postoperative pancreatic fistula.
RESUMO
As the capital WaS invested increasingly to key disciplines,the university regarded the performance.Strengthening the evaluation on performance will help to the development of the disciplines.The omni directional performance evaluation iS a mode of all orientation.which will help the performance evaluation of disciplines go on well.At the same time.it should be paid attention to the design of the evaluation index,and the selection of the persons ioining in the evaluation team and the time of the evaluation.
RESUMO
Objective To observe the effect of tyrosine kinase Src on activating Notch-1 protein in pancreatic cancer cell line-BxPC3. Methods Notch-1 expression and c-Src expression were inhibited by siRNA interference, and the activation of Src was inhibited by its inhibitor PP2. The growth rate of BxPC3 cells was measured by MTT. The change of Notch-1 NICD level and Src protein level was measured by Western blot. Results The growth of BxPC3 cells decreased after inhibiting Notch-1 expression, as well as the cells were treated with PP2. The level of Notch-1 NICD decreased both after inhibiting c-Src expression and after Src activation was inhibited by PP2. Conclusion In BxPC3 cells, tyrosine kinase Src promotes the level of Notch-1 NICD, which directly influences the cell growth.
RESUMO
Objective To elucidates the regulation of Notch1 activity by Rab5 which controls endosome fusion.Methods Rab5 expression of BxPC3 cells were inhibited by siRNA interference,the changes of Notch ICD protein were measured by Western blot.We use Wortmannin and LY294002 which inhibit the acticity of Phosphatidylinositol(PI) 3-kinases to investigate Notch ICD protein level.Results After inhibiting Rab5 expression or the activity of Phosphatidylinositol(PI) 3-kinases,Notch ICD protein level and the growth of BxPC3 cells decreased.Conclusion In BxPC3 cells,Rab5 and Phosphatidylinositol(PI) 3-kinases are important to regulate Notch1 activity and the activation of Notch is dependent on endocytosis.
RESUMO
Objective To investigate the effect of Notch1 and Jagged1 on the growth of prostate cancer PC3 cells and the regulation of Jagged1 expression by its receptor Notch1 in PC3. Methods Notch1 and Jagged1 expression were inhibited by siRNA interference. The growth rate of PC3 cells was measured by MTT. Notch1 expression was inhibited by siRNA interference and promoted by transfection of Notch1 cDNA. The changes of Notch1 and Jagged1 protein and mRNA levels were measured by Western blot and Real-time RCR. Results The growth of PC3 cells decreased after inhibiting Notch1 and Jagged1 expression. Jagged1 protein level decreased after inhibiting Notch1 expression and increased after over-expressing Notch1. Moreover, the change of Jagged1 protein level was discordant with the situation of mRNA. Conclusion In PC3 cells, Notch1 and Jagged1 are important to cell growth. Notch1 may regulate Jagged1 expression.
