We have performed systematical studies on intrauterine transmission of hepatitis B virus and our studies suggested that HBV may occur through progressive infection of different placental layers until the virus reaches the fetoplacental circulation, which is the named "transplacental cellular traffic" except through placental tears with transfusion of infected maternal blood into the fetal circulation, which is the named "hematogenous transmission".

我室近年来对HBV宫内传播进行了系列研究，发现了胎盘在宫内传播中的作用，并提出了HBV宫内传播机制的假设：除血源性途径外，还可通过HBV在胎盘组织内的&细胞传递&途径，即HBV可以从母体蜕膜细胞通过&逐层转移&至胎儿绒毛毛细血管内皮细胞，导致胎儿感染。

Results Astrocyte of rat optic nerve was cultured and purified,which showed positive reaction to glial fibrillary acidic protein.

Cases healthy subjects served as control. In addition, density of glomerular matrix membrane and quantity of cell in glomeruli were measured with CMIAS image analysis system by computer. Global sclerosis, cellular crescents, fiber or fibrocellular crescents were measured with Memphis scope. Tubulointerstitial lesions were examined with semi-quantitative grades (including O-III grades).Results Compared to normal control, there was a significant increase of urinary TGF-betaK IL-6 and Col-lV levels in patients with IgAN (p. 01). There were also significantly positive correlation between the levels of urinary TGF-betaK Col-IV and density of glomerular matrix membrane ., interstitial fibrosisp.
