Objective@#To investigate the expression of CD155/TIGIT in patients with osteosarcoma and its significance@*Methods @#The expression differences of CD155 and TIGIT in tumor tissues of distant metastatic osteosarcoma patients and non⁃metastatic osteosarcoma patients were analyzed by cancer Genome Atlas ( TCGA) database.The surgically removed tissues of osteosarcoma patients were collected to prepare pathological sections and tissue chips , and the tumor tissue and cell morphology were observed by HE staining. Immunohistochemical staining was used to detect the expression of CD155 and TIGIT , and the scores were divided into high expression group and low expression group according to the scores. Chi⁃square test was used to analyze the relationship between CD155/TIG⁃IT expression and clinical features and prognosis.@*Results @#TCGA database data showed higher expression of CD155 and TIGIT in patients with osteosarcoma accompanied by metastasis. HE staining of pathological sections revealed that tumor tissues with high expression of CD155/TIGIT contained more binuclear or multinucleated , hyperchromatic and obviously heteromorphic tumor cells. Immunohistochemical staining and score analysis of tissue chip showed that the expression of CD155 and TIGIT was correlated with clinical stage and distant metastasis ( P < 0. 05) , but not with age , sex , tumor size , pathological type and tumor necrosis rate. @*Conclusion@#CD155 and TIGIT may be one of the prognostic indicators of osteosarcoma.

Objective To evaluate the efficacy and safety of laparoscopic surgery in the treatment of gallstones and common bile duct stones.Methods Eighty-seven patients with gallstones complicated with common bile duct stones who underwent concurrent laparoscopic surgery at Zhoushan Hospital from December 2015 to December 2017 were enrolled.The patients were divided into A group and B group according to the digital table.A group (38 cases) underwent laparoscopic cholecystectomy (LC) combined with laparoscopic common bile duct exploration (LCBDE),and B group (49 cases) underwent endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterotomy (EST) combined with laparoscopic cholecystectomy (LC).The curative effect of the two groups was observed.The operation time,the success rate of the operation and the rate of laparotomy were recorded in the two groups.The corresponding hospitalization time and cost were compared.The safety of the two different procedures was compared after surgery,and the complications of the two groups were recorded.Results In A group,the average diameter of common bile duct stones was (1.02 ± 0.25) cm,the average diameter of common bile duct diameter was (1.15 ± 0.25) cm.In B group,the mean diameter of common bile duct stones was (0.99 ± 0.26) cm,and the average diameter of common bile duct was (1.13 ± 0.26) cm.The differences between the two groups were not statistically significant (t =0.513,0.437,0.367,P =2.083,1.533,1.095).The successful operation rate of A group was 92.11％ (35/38),which in B group was 91.84％ (45/49),the difference was not statistically significant between the two groups (x2 =0.006,P =0.974).The incidence rate of complications in B group was 20.41％,which was significantly higher than that in A group,the difference was statistically significant(x2 =3.654,P =0.019).The hospitalization time,hospitalization expenses in A group were (10.6 ± 2.6) d,(26 649.8 ± 3 478.6) CNY,respectively,which were significantly better than those in B group (t =21.971,17.168,all P ＜ 0.05).Conclusion The efficacy of LC combined with LCBDE for patients with gallstones complicated with common bile duct stones is better than ERCP/EST combined with LC surgery,and the safety of the former is higher than the latter.

Objective To investigate the effect of preoperative preplacement of nasobiliary drainage in radiofrequency ablation of small hepatocellular carcinoma at hepatic portal. Methods 7 patients with small hepatocellular carcinoma who were admitted to our hospital from June 2014 to June 2017 were selected. All patients were the cases who were prone to injure the bile duct at hepatic portal upon the radiofrequency electrode needle entering liver cancer in the small hepatocellular carcinoma at hepatic portal. The nasal bile duct was pre-placed preoperatively, and infusion of water into nasobiliary bile duct was conducted to expand the bile duct for intraoperative identification and avoiding false puncture. In some cases, after intraoperative bile duct injury, postoperative nasobiliary drainage was given to avoid obstructive jaundice or the occurrence of bile tumor at hepatic portal. Results The treatment effective rate in the patients was 100％ (7/7). Blood biochemistry, routine blood test, liver function were re-examined after surgery. Liver CT or MRI was reexamined 30 to 60 d after surgery. After the preplacement of nasal biliary, there was one case of pancreatitis, with the incidence rate of complications of 14. 3％. The long-term treatment effect was favorable, without tumor recur-rence. Conclusion For small hepatocellular carcinoma at hepatic portal, preoperative preplacment of nasobiliary drainage is used, and the direction of the bile duct during radiofrequency ablation can be clearly observed, so as to effectively avoid the bile duct injury.
