Objective To determine the significance of thymidine phosphorylase for prognosis of HCC.Methods The clinical data and pathological finding of 65 patients with HCC treated in our hospital were retrospectively analyzed.Immunohistochemical staining was performed to evaluate the expression of TP and MVD count.Statistical analysis was used to analyze the relationship between TP expression and other pathological parameters.Survival curves in 54 patients were plotted using the Kaplan-Meier method.Results The positive expressed rate of HCC tissues was significantly higher than that of normal liver tissues (P<0.01).MVD count in positive-TP group and negative-TP group was respectively 16.14±5.11,10.11±4.55.The difference between two groups had statistical significance (P<0.01).TP expression was positively correlated with tumor size,Edmondson-Steiner grade,tumor capsule status,microsatellite marker and tumor thrombi in portal vein (TTPV).The rate of postoperational recurrence after one,two and three years in TP-positive group was respectively 40%,66.7%,79.2% and it was respectively 27.4%,31.3% and 45.7% in TP-negative group.The postoperative recurrence rate after two years and three years in poitive-TP group was significantly higher than that in negative-TP group (P<0.01).In 54 patients with HCC followed up successfully,the total survival rate in TP-positive group was significantly lower than in TP-negative group (P<0.01).Conclusion TP plays an important role in neovascularization of HCC and TP may be a new prognosis index of HCC.

Objective To investigate the clinical and imaging features of von Hippel-Lindau disease to raise awareness of the disease. Methods The clinical and imaging data of a case of VHL patient were analyzed retrospectively and discussed with relative literature review. The patient was a 50-year-old man, who was admitted with the chief complaints of painless gross hematuria and blurred vision for 5 months. Imaging data and ophthalmoscopy examination showed bilateral multiple renal tumors, renal cysts, pancreatic cysts, hepatic cysts and retinal angioma in his right eye. He suffered a surgical operation for his cerebellar hemangioblastoma 12 years ago without family history. Results The patient underwent nephron- sparing surgery (NSS) in the left kidney. Five renal tumors were removed, and the largest tumor was 3.5 cm× 3.5 cm. Postoperative oral administration of Sorafenib agents was applied. Followed up for 4 months, the renal function was normal and the right kidney tumor reduced. Pathology confirmed the diagnosis of multiple renal clear cell carcinoma. Conclusions VHL disease is a familial autosomal dominant hereditary syndrome, with the performance of hemangioblastorna in central nervous system, visceral tumors and multiple visceral cysts. Comprehensive imaging examination plays a major role in both the diagnosis and the follow-up of VHL disease.

Objective To investigate the relationship of urinary vascular endothelial growth factor (VEGF) and occurrence and invasiveness of bladder cancer. Method The expression of urinary VEGF in 48 patients with bladder cancer (bladder cancer group) and 45 normal cases (control group) were examined by ELISA immunohistochemical staining. Results VEGF levels in urine in bladder cancer group [(174.77±83.41) μg/L] were higher statistically than those in control group [(63.53 ±22.62) μg/L] (P < 0.01), and related to the staging and grading of tumors. VEGF levels were significant higher in invasive lesions [(223.00 ± 83.13) μg/L] than those in superficial ones [(130.40 ± 54.86) μg/L] (P < 0.01). VEGF levels of G3 [(259.23 ± 75.82) μg/L] were significant higher compared with G1 [(138.00± 85.60) μ g/L] and G2 [(146.22 ±47.53) μ g/L] (P < 0.01). Conclusion The concentration of urinary VEGF relates to the clinical staging and pathological grading, and it is a labeling index of the biological behavior of bladder cancer.

Methods Before and after chemoembolizafion of therapy,the expression of Ki-67 in 30 patients of bladder cancer tissue were examined by immunohistochemical staining.The rehtion of its expression to the pathological grade and clinical stage was evaluated clinically.Results Positive rate of Ki-67 expression in the bladder cancer tissue was 70.00% and 26.67% respectively.There was significant difference between the before and after therapy (P＜0.01). Follow-up for mean 24.6 months recurrence rate in 30 cases was 16.67%.The expression of Ki-67 correhted to the pathological grade, clinical stage and patient recurrence rates of bladder cancer.Conclusions Preoperative arterial chemeembelization can reduce the expression of Ki-67,adjust malignancy of bladder cancer,could downgrade and downstage the tumors,and cut down the postoperative metastasis,improve survival rate and reduce recurrence rate.Both of the Ki-67 labeling index are predictive factor for recurrence of superficial bladder cancer.

Objective To study the influence of transeatheter bladder arterial chemoembolization on neovascularization and vascular endothelial growth factor (VEGF) expression in bladder cancer treatment. Methods Thirty bladder cancer patients (Tis =1, Ta =2, T1 =6, T2 =11, T3 =9, T4 = 1; G1 = 9, G2=13, G3 = 8) were treated with transcatheter arterial chemotherapy with Mitomycin (20 mg) or Hydroxycamptothecin (10 nag) adding cisplatin (60 rag) and embolization with gelatine sponge particle gelform 1 week before surgery. Before and after the chemoembolization, the expression of VEGF and microvessel density (MVD) count in cancer tissue were examined by SP immunohistochemical staining. Tumor samples after chemoembolization were taken and sent for pathological examination. The over all survival rates were recorded and analyzed as well. Results Before and after the chemoembolization, positive rates of VEGF expression in bladder cancer tissue were 73. 3% and 43.3%, respectively and MVD were 69.8±3.4 and 56. 4±3.3, respectively. There were significant differences between the parameters before and after the treatment (P<0.05). After the intervention, tumor diameter decreased from 2.2±0.9 cm to 1.6±0. 9 cm (P<0.05) and tumor tissues were in severe necrosis and degeneration. During the follow-up of 24. 6 months (ranging from 12 to 36 months),there were 5 recurrent cases (G1 T1 =1, G2 T1=1, G2T3=1, G3T3 = 1, G3 T4 =1, primary transitional cell carcinoma= 4, admixture carcinoma= 1). In the recurrent group, VEGF expression were positive in 5 cases (100% strong positive) and 4 cases (80%, 3 positive, 1 strong positive) (P>0. 05) before and after the chemoembolization. However, it had significant difference in strong positive expression (P<0.05); MVD were 87.4±3.0 and 72.4±4.1 (P<0.05) before and after the treatment. The MVD in no recurrent group was 53.2±3. 5 after chemoembolization, and it had statistical significance comparing with the recurrent group (P<0. 05). Conclusions The chemoembolization can decrease the expression of tumor VEGF and MVD. Thus, it can adjust bladder cancer malignancy, downgrade and downstage the tumors and decrease the risk of postoperative metastasis. For the long-term, this treatment will improve the survival rate and reduce recurrence rate.
