Adenoviruses harboring E. coli cytosine deaminase gene (AdCD) were used to transfect murine FBL-3 ery-throleukemia cells in vitro. FBL3 cells infected with AdCD were more sensitive to 5-fluorocytosine (5-FC) than cells infected with a control adenovirus AdLacZ. Further study indicated that this combination therapy (AdCD and 5-FC) killed tumor cells by inducing apoptosis of FBL-3 cells. The supematants from FBL-3 cells treated with AdCD/5-Fc were transferred on the culture system of uninfected (wild - type) FBL-3 cells, the result indicated that only 6.25% of the supernatant could induce significant cytotoxicity on wild type FBL3 cells. The results demonoustrated that bystander effect plays an important role in AdCD-mediated cytotoxicities. Direct injection of AdCD into established subcutaneous FBL3 tumor in mice followed by daily intraperitoneal injection of 5-FC for 10 days was found to inhibit tumor growth significant-

Antitumor effect of combined transfer of suicide gene and cytokine gene was evaluated in the present study. Adenoviruses expressing E. coli. cytosine deaminase (AdCD) and adenoviruses expressing murine interleukin 2 (AdTL2) were used for the treatment of tumor-bearing mice. The mice were inoculated s. c. with FBL-3 leukemia cells and 3 days later received intratumoral injection of AdCD in the presence or absence of AdIL2 followed by intraperitoneal 5-fluorocytosine (5FC) administration. The results demonstrated that tumor-bearing mice treated with AdCD/5FC in combination with AdTL2 showed more .potent inhibition of tumor growth and survived much longer as compared with mice treated with AdCD/5FC, AdEL2, AdlacZ/5FC or PBS. It was illustrated that the tumor mass showed obvious necrosis and inflammatory cell infiltration, and more CD4+ and CD8+ T cells infiltrated into the tumor after combined therapy. The splenic NK and CTL activities increased significantly in mice after combined transfer of CD gene and EH gene. Our results demonstrated that combined transfer of suicide gene and IL-2 gene could inhibit the growth of established tumor in mice significantly and induce antitumor immunity of the host efficiently.

OBJECTIVETo study the influence of alcohol on the liver sinusoids endothelial cell (LSEC) fenestrae of rats.

METHODSSetting up the rat model of alcoholic liver disease by orogastric administration of alcohol, then kill the experimental and control groups of rats at the end of 4 weeks, 8 weeks and 12 weeks after alcohol feeding, and also at the end of another 12 weeks after balance foods feeding succeeding with alcohol feeding for 12 weeks. Staining the liver tissue by means of HE method and observing the successive change of LSEC fenestrae by transmission electron microscope.

RESULTSThe normal LSEC was flat with nucleus and organelle arranged regularly. The distal cytoplasm displayed as lamina with many fenestrae, not accompanied by basement membrane (BM) formation under the endothelial cell. At the end of 4 weeks of alcohol feeding, fenestrae decreased at the partial distal LSEC cytoplasm, but no BM developed. At the end of 8 weeks, fenestrae decreased significantly, even disappeared, with the BM developed incompletely under the endothelial cell. Concomitantly, fibroblast with active function developed. At the end of 12 weeks, the changes became more obvious; the complete BM could even be seen. However, this kind of changes was mostly limited in the single or adjoining sinusoids, as well as with little widespread formation of fibrosis. At the end of 12 weeks of stopping alcohol feeding, defenestrae and development of BM attenuated obviously.

CONCLUSIONThe defenestrae and BM of LSEC develop gradually with the chronic alcohol stimulation. Sinusoid capillarization and liver fibrosis even form when significant changes happen. The early change of the limited defenestrae and capillarization may be the basis of alcohol periportal fibrosis formation. This kind of liver fibrosis can be reversible after stopping alcohol feeding.

OBJECTIVETo present data from a baseline investigation on stroke-related cohort population in rural area of Shanghai.

METHODSA cross-sectional study was carried out in a cluster sampling population aged 40 years and over. General information and data on common risk factors in the population were gathered and cerebral vascular hemodynamic indexes were checked. Hemodynamic score was estimated according to single indexes by unified methods. 5335 persons who had met the inclusion criteria were enlisted in the study. Exposure level of risk factors, prevalence of stroke, and hemodynamic indexes were analyzed and distributional characteristics were described.

RESULTSExposure rate of hypertension, heart disease, diabetes, family history of hypertension, overweight or obesity in males were 31.74%, 6.09%, 1.16%, 3.22%, 17.64%, 29.68% and were 32.76%, 9.22%, 1.55%, 3.84%, 19.22%, 29.44% in female respectively. Standard prevalence of stroke was 1167.3/100000, which in male was significantly higher than that in female (P < 0.05). The change of cerebral vascular hemodynamic indexes was significantly associated with age. Hemodynamic score in 21.3% of the subjects was below 75 points.

CONCLUSIONSAmong population of 40 years old and over in rural areas, hypertension was the principal risk factor regarding the rate of stroke. Prevalence of stroke in males was significantly higher than that in females. Abnormal rate of hemodynamic score was about 20% in this population.
