Effect of opsonized zpoosan on polymorphonuclear leukocyte (PMN)were studied by chemilundnescence (CL)and hydrogen peroxide (H2O2)assays. Results showed that different concentrations of Physalin B(PhB) presented a dose-dependent inhibitive effect on CL and H2O2 production of activated PMN. It suggested that the anti-inflammatory action of PhB may be related to the inhibition of production and release of oxygen free radical by PMN.

Objective To investigate the association between prodromal headache and the propensity of rebleeding after aneurysmal subarachnoid hemorrhage.Method Prodromal headache was defined as a sudden attack of severe headache lasting at least one hour with or without accompanying symptoms,not leading to a diagnosis of SAH 4 weeks before the confirmation of subarachnoid hemorrhage.Two hundred and nine patients with aneurymal subarachnoid hemorrhage were enrolled in this research.Age,gender,Hunt-Hess grade,D-dimer, (FBG),site and number of aneurysms and prodromal headache were recorded.Patients were divided into rebleeding group and non-rebleeding group.Comparing the above survey components between two groups was carried out by using case control study method.Age,aneurysm number,D-dimer and fibrinogen of the two groups were analyzed by t test.Prodromal headache,gender,site of aneurysms were analyzed by chi square test.Hunt- Hess grade was analyzed by rank test.Results Twenty-two(10.5%)patients had rebleeding.In the rebleeding group,10 patients(45.5%)had prodromal headache,while in the non-rebleeding group(n=187),21 patients (11.2%)had prodromal headache.Patients with prodromal headache had greater propensity of rebleeding compared with those without prodromal headache(P

Objective To analyze the application of recombinant VCA-BALF4(S) and VCA-BFRF3 proteins in serological diagnosis of nasopharyngeal carcinoma (NPC). Methods DNA extracted from the B95-8 cells was used as the templates in a polymerase chain reaction(PCR). VCA-BALF4 1008 bp (S) (aa 287-623) and VCA-BFRF3 531 bp(177 as) were generated and inserted into pPICZaA vector.The recombinant plasmids were transformed into GS115 yeast by electroporation. The yeast transformants in-duced by methanol expressed recombinant proteins. The recombinant proteins synthesized were coated to mi-croplate for detection of EBV-IgA antibody in NPC patients by ELISA. Results We have successfully se-cretly expressed the recombinant VCA-BALF4(S) and VCA-BFRF3 protein in the Pichia pastoris. The mo-lecular weight of products were approximately 37×10~3 and 18×10~3, respectively. The recombinant proteins VCA-BALF4(S) and VCA-BFRF3 in the culture supematant showed good immunoreactivity with IgA anti-bodies to EBV by Western blot. A novel ELISA was established using Pichia pastoris-expressed VCA-BALF4 (S) and VCA-BFRF3 proteins. Serum samples were collected from patients with NPC and healthy controls and using this ELISA tested. The sensitivity of VCA-BALF4(S) and VCA-BFRF3 tests in the NPC sera were 88.7% and 71.0%, whereas the specificity of normal individuals are 96.4% and 91.8% separately. Con-clusion The recombinant proteins BALF4 (S) and BFRF3 were highly secretly expressed in Pichia pastoris,the diagnostic value of two recombinant proteins in screening for NPC patients were primary evaluated and the valuable pPICZa-BALF4(S) yeast strain was obtained.

ObjectiveTo find out the electroencephalogram(EEG)change of the children with language retardation.MethodsThe EEG change and prognosis of 78 cases of language retardation children were analysed and compared with normal ones.ResultsThe EEG abnormal rate of language retardation was 69.3%,while that of the normal children was 10%(P<0.001).Conclusions The EEG is helpful to understand the developmental status of brain functions.
