International Journal of Cerebrovascular Diseases 2006;0(12):-
The etiology of reversible posterior leukoencephalopathy syndrome(RPLS)is more complex.Its pathogenesis has a lot of controversies,and its clinical manifestations are headache, nausea,vomiting,epileptic seizure,consciousness disturbance and visual abnormality.Neuroim- aging examinations have shown that diffuse symmetrical white matter edema is predominantly in the bilateral posterior brain regions.Clinical symptoms and neuroimaging changes can be recov- ered completely after timely and effective treatment.If the treatment is delayed,it may compli- cate with cerebral infarction or hemorrhage,and lead to irreversible damage.

OBJECTIVE To study the HBV-DNA level and its replication with only HBsAb positive for transplantation. METHODS Serial serum samples were studied with the quantitative determination of HBV-DNA by a quantitative PCR assay and determination of HBsAb by ELISA. RESULTS The positive rate of HBV-DNA was 8.4% in the patients with only HBsAb positive and that was 11.11% in the patients who had not been injected with vaccine;the level of HBV-DNA in 11 samples was less than 10~4 copies/ml and five samples showed the amount between 10~4-10~6 copies/ml.The positive rate of HBV-DNA was 8.4% in the patients with only HBsAb positive and that was 11.11% in the patients who had not been injected with vaccine;the level of HBV-DNA in 11 samples was less than 10~4 copies/ml and five samples showed the level between 10~4-10~6 copies/ml. CONCLUSIONS Patients with only HBsAb positive are still infective,which should be paid attention in transplantation.
