Objective To investigate the diagnosis and the microsurgical treatment of intramedullary hemangioblastoma in cervical spinal cord.Methods The signs of MRI,and the results of operations were analysed in 26 patients with the tumors.Rusults The tumors can be classified into two types:Solid type (14 cases)and cystic type(12 eases).All the tumors underwent total removal and were all hemangioblastoma confirmed by histopathologic examinations.Postoperatively,neurological status were improved in 17 patients, remained in 7 cases and worse in 2 cases.Conclusion For intrameduUary hemangioblastoma of cervical spinal cord MRI is of significant importance in the diagnosis of localization and the nature of the tumors which is conductive to selecting appropriate operative methods.There is high risk in operating at cervical section,but microsurgical total resection is the optimal method to stop the development of the clinical presentation.Opera- tive methods varied with the different typer of the tumor.It is the most important principal that dissection is performed along the correct interface and the tumor should be removed en bloc after it is devascularized.

·Age-related macular degeneration (AMD) and retinitis pigmentosa (RP) are common outer retinal degenerative problems, which are also the predominant causes of most blinding retinal diseases. Retinal prosthesis is a promising solution for such photoreceptor degeneration diseases.Most of current concepts for a retinal prosthesis are based on neuronal electrical stimulation. In the past twenty years, retinal prosthesis has been developed in two different directions: epiretinal prosthesis and subretinal prosthesis. Each prosthesis technique has its advantages and disadvantages. For epiretinal prosthesis, it is easier to be implanted and has the advantage of keeping most of the electronics in the vitreous cavity, off the retinal surface, which greatly helps in dissipating the heat generated by the implant device. In this paper, a brief overview of retinal prostheses concepts is introduced. After that, several important aspects of epiretinal electrical stimulation will be discussed. Moreover, some practical epiretinal prosthesis devices developed by researchers in United States, Germany and Japan in the past have been reviewed. We hope that the devices will be used widely in the near future.

OBJECTIVETo assess the value of multi-slice spiral computed tomography (MSCT) in the diagnosis of total anomalous pulmonary venous connection (TAPVC).

METHODSA retrospective analysis was conducted in 12 patients with the diagnosis of TAPVC established by MSCT. Multi-planar reconstruction (MPR), curved-planar reconstruction (CPR), volume rendering (VR), maximum intensity projection (MIP) and minimum intensity projection were performed in all the cases, and the results were analyzed in comparison with those of ultrasound echocardiography (12 cases) and surgical findings (10 cases). Cardiovascular angiography was performed in 2 cases.

RESULTSIn the 10 patients receiving surgical interventions, 7 presented with supracardiac TAPVC, 2 with cardiac TAPVC, and 1 with infracardiac TAPVC. MSCT allowed qualitative diagnosis and identified the location of the lesions in all the 10 surgical patients, whereas echocardiography established the diagnosis in only 5 patients. In the 2 cases undergoing cardiovascular angiography, the diagnosis was established in only 1 case without clear display of the draining vein.

CONCLUSIONMSCT combined with 3-dimensional reconstruction provides a noninvasive and accurate means for the diagnosis of TAPVC.

Objective To compaire results of recombinant virus assay and live virus assay on evaluateing anti-HIV-1 drugs. Methods The pseudoviruse was generated by cotransfection of the plasmid B01 containing gp160 genes and pSG3△ env plasmid. After co-incubation of pseudovirus with serially diluted drug, the EC50 and ED50 were calculated according to RLU(relative light unit) for each drug. After coincubation of live virus with serially diluted drug, the EC50 was calculated according to cytopathic effect.Results EC50 of IDV measured by the recombinant virus assay and live virus assay was 88.9 nmol/L, 89.5 nmol/L, respectively, while EC50 of NVP measured by the recombinant virus assay and live virus assay was 0. 36 μmol/L,0. 23 μmol/L, respectively. The recombinant virus assay showed good reproducibility with coefficient variation of 0, however coefficient variation of live virus assay reached to 60%. ED50 of IDV and NVP measured by the recombinant virus assay were 70.6 nmol/L and 0.62 μmol/L, respectively.Coefficient variations for IDV and NVP were 14.3% and 9.7%, respectively. Conclusion The pseudoviruses could be used in evaluating anti-HIV-1 drugs. The recombinant virus assay showed good reproducibility and could calculate not only the EC50 but also the ED50 of drugs.

OBJECTIVETo analyze the cervical cancer mortality and distribution profiles by areas and population in 2004 - 2005 and the changes in the last 30 years.

METHODSThe demographic information and cervical cancer death data came from the Third National Retrospective Sampling Survey of Death Causes which including 158 sampling areas (including 61 cities and 97 villages; 52 in the east region, 49 in the middle region and 57 in the west region) covered 31 province-level regions in the interior of China by multiple stage stratified clustering sampling. The total number of the samples were 142 660 482 person years (72 970 241 person years in male and 69 690 241 person years in female). The crude and age-specific death rate was calculated. The standardized death rate was calculated by using 5 years interval from the census data of 2000. In addition, the mortality data was compared with the two previous national death surveys in 1970's and 1990's, respectively.

RESULTSIn the sampling region of the third retrospective death causes survey from 2004 to 2005, the crude death rate of cervical cancer was 2.86/100 000 (1995/69 690 241), which accounting for 2.86% (1995/69 667) and ranking 9th of all cancer death causes in female population. The crude death rates of cervical cancer were 2.88/100 000 (1326/46 091 419) and 2.83/100 000 (669/23 598 822) for rural areas and urban areas, respectively, the Chinese population adjusted death rates of rural and urban areas were 2.01/100 000 and 1.67/100 000, respectively. The standardized death rates of cervical cancer in 1973 - 1975 and 1990 - 1992 were 11.10/100 000 and 3.25/100 000, respectively, which accounting for 17.91% and 4.86%, respectively; in 2004 - 2005, the crude death rates increased by age, rose remarkably from the age of 40 and arrived the peak of 20.83/100 000 (82/393 624) at the age of 85. The mortality among 35 - 44 year-old group was higher than those in 1990's. The crude death rates of the middle, west and east areas were 3.41/100 000 (827/24 225 738), 3.25/100 000 (636/19 563 647) and 2.05/100 000 (532/25 900 856), respectively, the Chinese population adjusted death rates of the middle and west areas were about twice that of the east (2.35/100 000 in the middle, 2.38/100 000 in the west, and 1.19/100 000 in the east).

CONCLUSIONThe mortality of cervical cancer was higher in rural areas than that in urban, as well as higher in the middle and west areas than that in east area in the interior of China in 2004 - 2005. Younger trend of cervical cancer death was observed; the mortality of cervical cancer and constituent ratio in the female tumor death continued to decline compared to those in 1973 - 1975 and 1990 - 1992.

With improved overall survival of cervical cancer patients, the importance of the quality of life (QOL) is increasingly recognized. This study was conducted to compare the QOL of women with different stage cervical cancer before and after treatment to facilitate improved cervical cancer prevention and treatment. We used the generic Medical Outcomes Study Short Form-36 (MOS SF-36) to collect QOL information. Based on SF-36, we interviewed cervical cancer patients at West China Second Affiliated Hospital and Sichuan Cancer Hospital between May 2010 and January 2011. A total of 92 patients with precancerous lesions, 93 with early cancer, and 35 with advanced cancer responded to our survey. Average physical component summary (PCS) scores were significantly different between the three groups at every time point (P < 0.05). Average mental component summary (MCS) scores were significantly different between the three groups after treatment (P < 0.05). Average PCS and MCS scores increased gradually from the pretreatment to posttreatment period for patients with precancerous lesions. However, they reached the lowest at 1 month after treatment for patients with early and advanced cancers and rebounded between 1 and 6 months after treatment. Our results indicate that patients with precancerous lesions and early cervical cancer show better overall QOL than do those with advanced cervical cancer. Additionally, patients with early cancer recover more quickly than do those with advanced cancer in terms of both physical and mental functions. Thus, early detection and treatment initiatives may improve the QOL for patients with precancerous lesions and cervical cancer.
