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.

Objective To investigate the prevalence of pulmonary acariasis among the employees working on traditional Chinese medicinal materials and observe the effect of treatment. Methods History inquiry, detection of mites in sputum, blood examination for eosinophils and specific antibodies, x-ray chest film were carried out for 327 workers involving in traditional Chinese medicinal materials. Mites were found in sputum in 121 persons who were then treated with metronidazole, twice a day with a daily dosage of 0.8g for seven days as a course of treatment. Two courses were conducted with an interval of 7-10 day. Prevalence and morbidity in different groups of occupation, age, and sex were analyzed. Results The overall infection rate of mites in sputum was 37.0% (121/327) with an average morbidity of 12.5% (41/327). Among the four types of worker investigated, the highest infection rate (51.8%), and morbidity (18.6%) were in those working in transfer warehouse; the second highest infection rate (40.7%) and morbidity (15.7%) were in employees in factory of Chinese traditional medicine. Both groups showed a significant difference with others(?2inf=11.36,P0.05). After treatment with metronidazole, 88.4% showed negative in sputum examination for mites and the efficacy of the treatment for pulmonary acariasis was 92.3%. Conclusions Employees engaged in traditional Chinese medicinal materials are one of the groups at the highest risk of pulmonary acariasis. Metronidazole is effective in treating the infection.

Objective To compare the infectivity between laboratory adapted human inununodefi- ciency virus(HIV-1) and primary HIV-1 isolates for different mucosal epithelial cell lines. Methods Mu-cosal epithelial cells Caco-2, T-84, HeLa and lymphocyte MT-4 were infected with laboratory adapted HIV-1 SF33 and 2 primary HIV-1 isolates (02010561, 02010141). Culture supernatant and cells were collected respectively on 3-4 days interval after virus inoculation. The former was tested for HIV-1 antigen P24 level and viral load, and the latter was tested for total viral DNA and integrated viral DNA. Results All 3 virus strains could infect MT-4 cells and integrate into their genome. Only HIV-1 SF33 could infect Caco-2 cells but could not integrate into their genomic DNA. Both HIV-1 SF33 and 02010561 infected HeLa cells but only integration of HIV-1 SF33 was detected. All the 3 HIV-1 strains infected T-84 cells but only the integra-tion of HIV-1 SF33 and 02010141 was observed. Conclusion Although laboratory adapted and primary HIV-1 strains are able to infect human mucosal epithelial cell lines, transient or productive infection estab-lished in different mucosal epithelial cells is dependent on the character of cells and virus strains.

BACKGROUND: Demineralized bone matrix and bone morphogenetic protein have been shown to have good bone induction, but less studies concerned nanometer demineralized bone matrix. Its physical and chemical properties and biological security are not yet clear.
OBJECTIVE:On the basis of preparing the nanometer human demineralized bone matrix in previous experiment, we mixed the recombinant human bone morphogenetic protein-2 together to obtain the new bone graft substitute and to research its physical and chemical properties and biological security.
METHODS:The human demineralized bone matrixes were prepared by the method of modified Urist and nano-processed then mixed with the bone morphogenetic protein-2 in specific proportions in order to be lyophilized to complete the fol owing experiments. (1) Pyrogen experiment:the material extracts were injected in the rabbits by ear intravenous. (2) Toxicity experiments:material extracts and saline were separately injected via the tail vein of mice in vivo. (3) Implantation experiments:experimental materials andβ-tricalcium phosphate were implanted into rabbits on both sides of the hindlimb muscle.
RESULTS AND CONCLUSION:After lyophilized shaping, the nanometer demineralized bone matrix material had dense surface and it’s pore diameter was 100-400μm. The pore distribution was less uniform and the porosity was of less than 30%. The main elements were carbon, oxygen and nitrogen. Nanometer human demineralized bone matrix with recombinant human bone morphogenetic protein-2 did not have pyrogen effect and the rabbits’ body temperature had no significant fluctuations after injection. The acute systemic toxicity test results showed that the nanometer human demineralized bone matrix with recombinant human bone morphogenetic protein-2 complied with the relevant provisions of the State, without obvious toxic reaction. The inflammatory response of nanometer human demineralized bone matrix with recombinant human bone morphogenetic protein-2 was significantly lighter than the reaction ofβ-tricalcium phosphate. The results showed that the nanometer human demineralized bone matrix with recombinant human bone morphogenetic protein-2 is a nanometer al ogeneic bone graft substitutes with nontoxicity, good biocompatibility, high bioavailability, and less inflammatory reaction.
