Purpose To investigate the significance of arterial phase display of right ovarian vein (ROV) for patients with pelvic congestion syndrome (PCS) through multi-slice CT angiography (MSCTA) Materials and Methods Forty-three patients with PCS confirmed clinically who underwent MSCTA were involved in the study. Revascularization was realized via add vessel volume rendering technique and maximum intensity projection (MIP) and the relationships among ROV early development, location of converging vascular, development of LOV and pelvic draining veins were analyzed. Results Out of 43 cases of ROV early development during arterial phase, 21 cases (48.8%) took ROV as draining vein of PCS, among which 17 cases (81.0%) converged into the inferior cava vena. In 19 cases (44.2%), ROV took part in the formation of PCS, all originating from the main right renal vein. Three cases (7.0%) were renal vein-derived PCS, among which two ROV originated from the main right renal vein and one from the branch of the right renal vein. Conclusion According to the imaging features of bilateral ovarian veins and pelvic veins, ROV, as draining veins, is associated with the formation of PCS.

Objective:To observe the effect of Kechuanning on Th cytokine expression in pediatric virus-induced asthma.Methods:120 cases of pediatric virus-induced asthma were randomly divided into Kechuanning group(treatment group,n =60,treated with Kechuanning) and Western medicine group(control group,n=60,treated with virazole).The change of Th1 cytokine IL-12 and Th2 cytokine IL-4 in blood serum were detected and analyzed.Results:Kechuanning could increase IL-12 but decrease IL-4 level in the patient's blood,therefore regulate Th cell subset,and the effect was more obvious than in control group.Conclusion:The mechanism of Kechuanning in curing pediatrics asthma induced by virus was related with increasing IL-12 and decreasing IL-4 level.

Objective To analyze the characteristics and prognostic factors of gallbladder carcinoma and investigate the measures of various modus operandi. Methods The clinicopathological data of 181 patients with advanced gallbladder carcinoma treated in our hospital from June 2002 to June 2008 were retrospectively analyzed. SPSS16. 0 software package was used for statistical analysis.Results The overall median survival rate of the 181 patients with gallbladder carcinoma was 6 months. The median survival rate after radical resection for gallbladder carcinoma was 19.5 months,which was remarkably higher than other R1 resection, R2 resection and palliative operation groups (P ＜0. 01) The RO resection rates were 95.5%, 62. 2%, 14.1% and 4.7%, respectively based on different pathological stages of Nevin( Ⅱ , Ⅲ, Ⅳ, and Ⅴ ). There were significant differences among all groups (P＜0.01). The Cox multivariate analysis revealed that pathological stages of Nevin, total bilirubin, CA-199 and therapeutic method had significantly higher risk ratios for gallbladder carcinoma.Conclusion Radical resection may help to improve the survival rate and prognosis of advanced gallbladder carcinoma.

Objective To compare the safety and damage to liver function of 3 methods of hepatic infusive vascular occlusion in hepatectomy for hepatocellular carcinoma. Methods Retrospectively, the clinical data of patients undergoing curative liver resection with pan- (n=30) and hemi(n= 30) vascular occlusion or hemi-hepatic artery reservation (n= 30) method were analyzed. Results All patients in the 3 groups had similar surgical duration and blood loss. Two and one patients from group 2 suffered from portal vein impairment and hemorrhea, respectively. Patients from group 1 had higher serum alanine aminotransferase and total bilirubin on days 1 and 7 after surgery. Conclusion Hepatectomy with hemi-hepatic artery reservation, which was not closely related to hepatic hilum, is safe and convenient for the resection of tumor involving hemi-liver and is especially suitable for the patients with severe liver cirrhosis.
