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 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.

Objective To explore the feasibility of somatosensory evoked potentials (SEP) evaluating Tourette syndrome, based on the theory of SEP evaluating sensory-motor cortical function. Methods 33 cases of Tourette syndrome in our hospital from March 2014 to April 2015 were as the experiment group and 30 healthy participants were as the normal control group. Both groups were evaluated with Yale Global Tic Severity Scale (YGTSS) and SEP. Results There was no significant difference in N20 leak latency and leak-leak amplitude of SEP between 2 groups (P>0.05). The P22 leak latency prolonged (t=2.356, P<0.05) and the leak-leak amplitude decreased (t=2.507, P<0.05) in the experiment group compared with the normal control group. The YGTSS score was higher in the experiment group than in the normal control group (t=3.012, P<0.01). The P22 leak latency was positively (r=0.402, P<0.001), and the P22 leak-leak amplitude was negatively (r=-0.180, P<0.001) correlated with YGTSS score. Conclusion Children with Tourette syndrome are disordered in inhibiting sensory or mo-tor impulse through cortex-striatum-thalamus-cortex regulation circuit. SEP is considered as the objective indicator of patients with Tourette syndrome.
