Objective To investigate the therapeutic method and effect of thrombolysis via super-selective ophthalmic artery catheterization treating central retinal artery occlusion (CRAO). Methods 9 patients with CRAO were treated by urokinase infusion via super-selective ophthalmic artery catheterization with Seldinger technique. Results In the 9 patients, the visual acuity was improved to different extent in 8, and remained unchanged in 1. No complications was found during the treatment in any patients. Conclusions Thrombolysis via super-selective ophthalmic artery catheterization for CRAO can improve the visual acuity of most of the patients in different degrees. No positive relation exists in clinical therapeutic effect, time of onset, quantity of urokinase and the visual acuity before the treatment. The method of thrombolysis via super-selective ophthalmic artery catheterization for CRVO is safe and reliable.

OBJECTIVE To investigate the significance of expression of p53, Mdm2 and p21WAF/ CIP1 proteins and their relationships. METHODS Pathological specimens from thyroid carcinoma, adjacent non-tumor thyroid tissues and thyroid benign lesions were examined for p53, Mdm2 and p21WAF/CIP1 proteins by tissue microarray technique and immunohistochemistry method. RESULTS The positive expression rate of p53, Mdm2 and p21WAF/CIP1 in thyroid carcinoma was 50.6 %(37/73), 63.0 %(47/73) and 38.4 %(28/73) respectively. The expression of p53 and Mdm2 increased(P

Objective To explore factors influencing the prognosis of hepatocellular carcinoma (HCC) patients after hepatectomy. Methods From May 1994 to January 1998, 189 patients who underwent hepatectomy for HCC were enrolled for reviewing their clinical characteristics, treatment and prognosis. Twenty-two parameters contributing to long-term survival rate (SR) and disease-free SR were analysed. Results The 3,5-year cumulative SR of the whole group was 63%,45%, respectively. The 3,5-year SR and disease-free SR in the curative resection (CR) group ( n =162) were 67%,47% and 45%,26% respectively. Results showed that the way by which a tumor was found, tumor size, portal tumor thrombi, satellite nodule, TNM stage, cirrhosis type, recurrent and treatment, blood transfusion, differentiation grade,and CR were risk factors by individual variable analysis( P =0.0000～0.0034); A multivariable analysis showed that CR, tumor size, tumor finding mode and reoperation were significant factors associating with prognosis( P =0.0000～0.0024). Blood transfusion and type of cirrhosis were closely correlated with tumor-free survival ( P =0.0001). Conclusions Curative resection, tumor size, reoperation for recurrence were important factors for recurrence by multivariate analysis. The severity of concomittant liver cirrhosis and perioperative blood transfusion were closely correlated with postoperative tumor free survival.

OBJECTIVETo assess the safety, feasibility and clinical outcome of laparoscopic radical resection for low rectal cancer with telescopic anastomosis or with colostomy by stapler through transanal resection without abdominal incisions.

METHODSFrom January 2010 to September 2014, 37 patients underwent laparoscopic radical resection for low rectal cancer through transanal resection without abdominal incisions. The tumors were 4-7 cm above the anal verge. On preoperative assessment, 26 cases were T1N0M0 and 11 were T2N0M0.

RESULTSFor all cases, successful surgery was performed. In telescopic anastomosis group, the mean operative time was (178±21) min, with average blood loss of (76±11) ml and (13±7) lymph nodes harvested. Return of bowel function was (3.0±1.2) d and the hospital stay was (12.0±4.2) d without postoperative complications. Patients were followed up for 3-45 months. Twelve months after surgery, 94.6%(35/37) patients achieved anal function Kirwan grade 1, indicating that their anal function returned to normal.

CONCLUSIONSLaparoscopic radical resection for low rectal cancer with telescopic anastomosis or colostomy by stapler through transanal resection without abdominal incisions is safe and feasible. Satisfactory clinical outcome can be achieved mini-invasively.
