Objective To study the necessirity of endocrine treatment for thyroid adenoma after operation. Methods TSH receptors were determined in 100 patient's thyroid adenoma specimens with SP method. The continuous pathologic sections of the thyroid tissues around the tumor were examined to find out that if there was any small focus. The patients were divided into two groups radnomly: Group A, patients received thyroid hormone(TH) treatment after operation; Group B, the patients received no TH treatment after operation. Blood T 3, T 4 and TSH concentration were determined, and the residual thyroid was examined with 131 I scanning and ultrasunography peroidically after operation. Results TSH receptors were presented in all of the thyroid adenomas, and small focus presented in 8% of the patients. Blood T 3, T 4, TSH and residual thyroid were normal in all patients in group A. In group B, Blood T 3, T 4 were below the normal lever in 45(90%), TSH over normal lever in 41(82%),residual thyroid hyperplasia and enlargement were found in 48 patients(96%), and thyroid nodule or tumor in 33(66%). Conclusions TH should be taken in patients with thyroid adenoma after operation to prevent high TSH of serum and tumor replapse, because these patients have the characteristics of muttiple focuses of tumor and postoperative hypothyroidism.

Objective To evaluate the effect of a protein kinase CK2 inhibitor on intracellular levels of reactive oxygen species and DNA double?stand break in human non?small cell lung cancer H460 cells. Methods H460 cells were exposed to 0, 12?5, 25.0, and 50.0μmol/L quinalizarin, a specific inhibitor of protein kinase CK2, for 24 hours. The changes in protein and mRNA levels of CK2 subunits were measured. Flow cytometry was used to measure changes in the intracellular levels of reactive oxygen species in H460 cells after 4 or 24 hours of quinalizarin treatment. Immunofluorescence assays were performed to determine the effect of the CK2 inhibitor onγ?H2 AX expression and the average fluorescent number ofγ?H2 AX foci in H460 cells. Comparison was made by analysis of variance and t test. Results There were no significant differences in protein or mRNA levels of CK2 subunits in H460 cells after quinalizarin treatment ( CK2α,0μmol vs. 12?5 μmol/L, P=0?966;0 μmol/L vs. 25 μmol/L, P=0?355;0 μmol/L vs. 50 μmol/L, P=0?864, CK2α’ , 0 μmol/L vs. 12?5μmol/L,P=0?409;0μmol/L vs. 25μmol/L,P=0?833;0μmol/L vs. 50 μmol/L, P=0?0. 746, CK2β, 0 μmol/L vs. 12?5 μmol/L, P=0?532;0 μmol/L vs. 25 μmol/L, P=0?830;0 μmol/L vs. 50 μmol/L, P= 0?061 ) . The intracellular levels of reactive oxygen species were substantially elevated in H460 cells with the increase in quinalizarin concentration and treatment time. Different concentrations of quinalizarin resulted in dose?and time?dependent increases in the numbers of γ?H2 AX foci after 4 and 24 hours of treatment ( treated by Quianlizarin for 4 or 24 h, 0 μmol/L vs. 12?5μmol/L,12?5 μmol/L vs. 25 μmol/L, 25 μmol/L vs. 50 μmol/L, all P=0?000, concentration is 12?5μmol/L,25 μmol/L or 50 μmol/L, 4 h vs. 24 h, all all P=0?000 ) . Conclusions Quinalizarin can increase the intracellular levels of reactive oxygen species and DNA double?stand break in H460 cells by inhibition of protein kinase CK2 activity. This study provides a theoretical basis for using quinalizarin as a potential radiosensitizer for lung cancer.

Objective:To investigate the relationship between microsatellite instability (MSI) , and clinicopathological features ,prognosis in patients with stage Ⅱ and Ⅲ colon cancer.Methods:Patients undergoing surgical resection for stage Ⅱ and Ⅲ colonic tumor in the Affiliated Hospital of Qingdao University from Dec 2016 to Nov 2018 were enrolled. All the 292 patients were with stage Ⅱ and Ⅲ colon cancer and MSI status. Propensity score matching method was used to match the two groups of patients according to 1:1. χ 2 analysis, Logistic Regression and COX regression was used to analyse the relationship between MSI status, the clinicopathological features and prognosis. Results:The risk of MSI-H in young patients ( OR=0.340, 95% CI: 0.126~0.921, P=0.034), right-sided colon cancer ( OR=7.985, 95% CI: 3.040-20.973, P<0.001), mucinous adenocarcinoma ( OR=4.285, 95% CI: 1.495-12.284, P=0.007), poorer differentiation ( OR=4.848, 95% CI: 1.597-14.716, P=0.005), N0 staging ( OR=0.235 , 95% CI: 0.077-0.719, P=0.011) increased . The total OS of colon cancer patients in the MSS group (66.7%) and the MSI-H group (86.9%) were statistically different( P=0.003). The MSI status ( HR=0.367, 95% CI: 0.151-0.891, P=0.027) is an independent factor affecting the prognosis of patients. Conclusions:In stage Ⅱ and Ⅲ colon cancer, patients with MSI-H have a better prognosis. MSI status is prognosis relevant factor for colon cancer patients.

Objective To investigate the effect of continuous quality improvement on subjective well-being quality of life and satisfaction of esophageal cancer patients. Methods A total of 120 esophageal cancer patients in our hospital were randomly divided into two groups, 60 cases in the observation group treated with continuous quality improvement while the other 60 cases in the control group treated with routine care. The two groups were compared in terms of subjective well-being,quality of life and nursing satisfaction. Results Before the intervention, there were no significant differences between the two groups in view of the quality of life scale score and subjective well-being score (P>0.05). After the intervention, in view of symptoms, the scores on all the items in the boservation group were significantly lower than those in the control group (P<0.05), except constipation, economic difficulty and diarrhea and the function items were higher. The subjective satisfaction of the observation group was significantly better than that of the control group (P<0.05). Conclusion Continuous quality improvement care can promote the improvement of subjective well-being, improve the quality of life and satisfaction of patients with esophageal cancer.

Objective:To evaluate the curative effect, safety and feasibility of percutaneous transhepatic cholangio drainage(PTCD) combined with balloon dilatation in treating benign biliary-enteric anastomosis stricture(BBES).Methods:The clinical data of 33 patients with benign biliary-enteric anastomosis stricture, who were admitted to the First Affiliated Hospital of Zhengzhou University during the period from January 2013 to May 2019, were retrospectively analyzed. There were 23 cases of benign etiology and 10 cases of malignant etiology, benign strictures of which 15 cases were located in the hepatic hilum and of which 18 cases outside of it. All patients were considered as benign stenosis by at least two imaging examinations of magnetic resonance imaging of pancreatic or enhanced MRI or enhanced CT, laboratory examinations of tumor markers and other clinical data before operation. 10 cases of malignant etiology were confirmed by intraoperative biopsy and pathology. All patients were treated with balloon dilatation at an interval of 1 to 4 weeks after PTCD. The changes of clinical symptoms, bilirubin and liver function before and after operation were compared and analyzed, and the postoperative complications and anastomotic patency rate were followed up.Results:PTCD combined with balloon dilatation was performed successfully in all patients, and the success rate was 100%. After operation, the benign biliary-enteric anastomosis stricture was significantly improved in all patients, and the clinical symptoms were improved obviously. The liver function and bilirubin decreased significantly in all patients after operation, and there was significant statistical significance ( P<0.05). There is no serious complications such as biliary bleeding and biliary fistula were found after operation. At 3 months, 6 months, 12 months, 24 months and 36 months after operation, the anastomotic patency rates of all patients were 90.9%(30/33), 72.7%(24/33), 63.6%(21/33), 63.6%(21/33), 60.6%(20/33), respectively. During the whole follow-up period, anastomotic restenosis happened in 13 patients, of which 9 cases with restenosis, the benign stenosis site of the anastomosis was the hepatic hilum and of which 4 cases located on the outside of the hepatic hilum. After treatment, the incidence of benign restenosis of the anastomosis at the hepatic hilum (60.0%, 9/15) was higher than that at outside of the hepatic hilum (22.2%, 4/18) and it's statistically significant ( P<0.05). Among the 13 patients with recurrence of BBES, 4 cases underwent choledochojejunostomy for malignant causes and 9 cases with benign causes. The recurrence rates after the first balloon dilatation were 40.0% (4/10) and 39.1% (9/23), respectively, and the average recurrence time was 5.8 months and 6.8 months respectively, the difference was not statistically significant( P>0.05). Conclusion:For the treatment of benign biliary-enteric anastomosis stricture, percutaneous transhepatic cholangio drainage combined with balloon dilatation with reliable curative effect, with high safety and less trauma, with less operative complications, and with repeatability, so it is worth applying in clinic.
