Aim To identify the GABA transporter subtypes and to find its new associated member at the blood brain barrier.Methods Labeled by in vitro infusion of magnetic beads through carotid arteries,the brain microvessels without intact neural cells were sorted in magnetic fields,and identified by RT PCR.The homologous primer of GAT superfamily and the tRNA from isolated brain microvessels were used in the RT PCR to amplify target DNA.The PCR products were isolated by polyacrylamide gel electrophoresis(PAGE) and cloned, sequenced rospectively.The sequences were screened in dbEST of Genbank by Blast.Results Seven DNA bands were isolated from RT PCR products of isolated brain microvessels by PAGE. B3,B5 complete sequences were highly homologous with rat partial GAT 2 and BGT 1 respectively,B7 complete sequence was highly homologous with rat partial TAUT. The other 4 EST of B1(Accession No:CF358965), B2(CD568346), B4(CF358966) and B6(CD568347) were submitted to dbEST,they were homologous with some sequences in Genbank,but were not homologous with GAT members.Conclusion GAT 2 and BGT 1 of GAT and TAUT were localized at the blood brain barrier which might be responsible for the GABA transport across the blood brain barrier.The genes and their functions of 4 EST associated with GAT need to be clarified.

The indexes of teaching quality evaluation,such as attitude,teaching and evaluation,contents and methods,and evaluation standards,such as "excellent,good,medium,bad,worse",show the characteristics of inaccuracy.While traditional evaluation methods focus on accurate figures,the paper proposes a new method which is based on fuzzy mathematics to evaluate teaching quality.The theory,computing procedure and examples of the method are introduced.

BACKGROUND:With elevated medical levels, limb salvage surgery for limb malignant tumor is valuable day by day. At present, the limb salvage surgery has substituted amputation and becomes mainstream and development direction of present surgical treatment of limb tumors. However, so far, there are no unified surgical indications for proximal femur tumor, which are controversial. OBJECTIVE:To investigate the efficacy of artificial total hip arthroplasty combined with extended resection of tumor sections for proximal femoral bone tumors. METHODS:Patients with proximal femoral bone tumors in the Second Xiangya Hospital of Central South University were selected and divided into control group and observation group, with 30 patients in each group. According to the disease, lesion curettage, aneurysm wal inactivation, autologous and (or) al ogeneic bone, mixed bone graft and bone graft fixation were selected to treat the control group. The observation group patients received extended resection of tumor sections and total hip arthroplasty. The operative time, intraoperative blood loss, hospital stay and joint function of two groups were compared. 2 years later, patients were revisited. Metastasis and recurrence rate, death rate and quality of life of two groups were compared. RESULTS AND CONCLUSION:There was no significant difference in intraoperative blood loss and surgery time between the two groups (P>0.05). However, hospital stay of patients in the observation group was shorter than the control group. The excellent and good rate of recovery of joint function (83%) was higher in the observation group than in the control group (53%). The metastasis and recurrence rate within 2 years after surgery (7%) and death rate (3%) were lower in the observation group than in the control group (30%, 23%). Various indicators of quality of life of patients in the observation group were significantly better than the control group (P<0.05). These results confirmed that artificial total hip arthroplasty in the treatment of proximal femur tumors is safe and effective.

During the development of pancreatic cancer,the local and whole immune state of the patients is constantly changing,and through which the cancer cells escape from the immune attack.The main immunologic mechanism includes the induction of tumor immune suppression cells and producing the related cytokines.The changes of the whole immune status include the increase of immunosuppressive cells,the change of the immune function of T cell subsets and the inhibition of natural killers and lymphokine activated killer cells.In the local tumor,the infiltrating lymphocytes loss the function,and the ratio of Thl/Th2 cytokines is imbalance.

Twenty four hours after occluding of the middle cerebral artery in rats, thecirculating neutrophils were in activated state and the lipidperoxidation increased in ische-mic brain tissue. Tanshinone inhibited the chemoluminescence of the circulating neutrophilphagocytosis and decreased leukocyte infiltration in infarcted brain tissue. It alsodecreased lipoperoxide, malondialdehyde and increased SOD activity in ischemic cerebralregion. In addition, it reduced cerebral infarction size in the model. The correlationbetween inhibitory effects on leukocyte and reduction in ischemic cerebral damage wassignificant. Dexamethasone used as a positive control had similar effects on neutrophils andischemic cerebral injury. It was shown that the prophylactic effcts of Tanshinone oncerebral infarction might be mainly due to its inhibition on leukocyte function.
