Objective To investigate changes in serum level of glial fibrillary acidic protein (GFAP) in patients with Parkinson disease (PD) and its clinical significance. Methods Serum GFAP was determined with sandwich ELISA for 82 patients with PD and acute cerebral infarction (ACI), as well as healthy normal controls. Patients with PD were then divided into two sub-groups in terms of their course duration, one with less than five years and the other with more than or equal to five years. Effects of course duration and age of the patients on their serum GFAP were analyzed. Results Serum level of GFAP was significantly higher in patients with PD [(1.628±0.104) μg/L] and ACI [(1. 637±0. 063 )μg/L] than that in healthy normal controls [ (0. 025±0. 003)μg/L, t = 82. 7, 142. 2, all P <0. 05 ]. But, there was no significant difference in serum GFAP between patients with PD and ACI ( t =0. 214, P > 0. 05 ). Serum level of GFAP in PD patients had no significant correlation with their age. There was no significant difference in serum GFAP between two sub-groups of patients with PD (P > 0.05 ). Conclusions Serum level of GFAP increased significantly in PD patients, as compared to healthy normal controls, but it is not specific. Serum GFAP in patients with PD maintained at certain high level with progression of the disease, indicating effect of astrocytes may persistently exist during the disease course.

AIM:To synthesize the human platelet factor-4(hPF4) gene with a convenient and effective approach, and high express the hPF4 gene in E. coli BL21 (DE3). METHODS: According to the primary structure of hPF4, the nucleotide sequence was synthesized using touch-down PCR method. The resultant gene fragment containing EcoR Ⅰ and Xho Ⅰ overhangs at 5' and 3' ends was cloned into the expression vector pGEX-4T-1 to construct the recombinant plasmid pGEX-4T-1-hPF4,which was then transformed into the E. coli strain BL21 (DE3). RESULTS: hPF4 gene was successfully synthesized by touchdown PCR method. A fusion protein composed of glutathione S-transferase (GST) and the recombinant hPF4 was expressed in BL21(DE3) by IPTG induction. The expression level of the fusion protein in E. coli was about 30% of the total cellular protein. CONCLUSION: Touch-down PCR may provide a convenient and effective approach to obtain other target genes. The expressed fusion protein forms the inclusion bodies, providing sufficient material for further purification and biological activities process.

Objective To investigate the effect of taurine transporter in the process of protection of brain edema in rats with severe traumatic head injury. Methods A total of 24 Male Sprague-Dawley rats were randomly divided into 4 groups. Except the control rats (Group Sham), all other three groups were subjected to lateral fluid percussion head injury. The TBI (Traumatic brain injury) models (Group TBI) and surgical control rats (Group Sham) were injected with saline through caudal vein after surgery, while the Taurine prevention and Taurine treatment models (Group Pre Tau and Group Tau) were injected with 120 g/L taurine solution before or after surgeries respectively. Water content in each brain, mRNA and protein expres?sion of aquaporin 4 and taurine transporter in the injured rat brain hemispheres were all evaluated over the time course of the study (7 d) in each group. Results Compared with rats in Group Sham, water content in each brain increase, mRNA tran?scription and protein expression of AQP4 were both up regulated but the mRNA transcription and protein expression of TauT were both down-regulated in rats in TBI group. Compared with rats in TBI group, brain water content, mRNA transcription and protein expression of AQP4 all decrease while mRNA transcription and protein expression of TauT all increase in rats in Pre tau and Tau groups. There is no statistical difference of TauT expression between rats in pre-tau group and Tau group. Conclusion Taurine exert its neuron protection role through draining water content from brain and down regulating expres?sion of AQP4 but rising expression of TauT after TBI.
