The gamma-secretase complex mediates the final cleavage of APP to generate the principal component of amyloid plaques in the brains of Alzheimer's disease patients.Four integral membrane proteins (PS,NCT,PEN-2 and APH-1) are essential and sufficient for gamma-secretase activity.To identify the promoter of human nicastrin gene (NCT),its 5' -flanking region has been characterized and a 270 bp fragment containing the TSS (transcription start site) for the promoter activity has been identified.EMSA assays confirmed that all four AP-1 binding sites and two NFAT sites in the NCT promoter region were able to bind relative transcription factors in vitro.Mutations,as well as treatment with PDTC,which adjust the regulatory effect of AP-1 and NFAT,altered NCT promoter activity in both HeLa cells and rat cortical neurons.The results demonstrated that AP-1 and NFAT are involved in the regulation of hNCT transcription and suggest that balanced activation of AP-1 and NFAT ensures a strict temporal and tissue-specific control of NCT transcription.

The aim of the paper is to prepare stable antisense oligodeoxynucleotides-loaded cationic liposomes and evaluate the transfection efficiency of asODN to MCF-7 oophoroma cells and study their distribution to different tissues in mice. Antisense oligodeoxynucleotides (asODN)-loaded cationic liposomes were prepared by a thin film-adsorption-lyophilization method which is simple and can overcome crucial pharmaceutical defects (e.g. instability) of liposomes during storage. The morphology was investigated by transmission electron microscope. The size and surface charge of the liposomes were determined by laser particle analyter. The dissociated ligodeoxynucleotides were separated from the liposomes by sephadex column and the entrapment efficiency was determined by using an ultraviolet photometer. Trehalose, mannitol, and glycine were suitable for lyophilization especially trehalose. The resulting liposomes were global microcapsule in a narrow particle size with a mean diameter of 175 nm and 320 nm before and after lyophilization, and a high zeta potentials of +32 mV. The dissociated asODN were separated from the liposomes by sephadex G-50 column and the entrapment coefficient of asODN was 88.4% pre and 83.2% post-lyophilization separately for trehalose. The growth of MCF-7 oophoroma cells were inhibited in vitro obviously (P < 0.05) and transfection efficiency of asODN was 18%, 26%, 44% after 2 h, 4 h and 8 h, respectively. The formulation and method can be used to prepare stable cationic liposomes which can effectively inhibit the growth of MCF-7 oophoroma cells and obtain a high transfection efficiency. This system can improve distribution amount of asODN to tissues especially tumors in mice.

OBJECTIVETo observe a turning performance in the rats excited by using a proper electrical stimuli of the barrel cortex region (BC), and the expression of choline acetyltransferase (ChAT) in the BC regions after electoral stimulation.
METHODSSD rats were divided into three groups. The stimulation electrodes were surgically implanted into the bilateral BC regions in the control group and the experimental group rats. The experiment group post surgery for seven days was given the electrical impulses via connection with the electrodes for three times each day through consecutive three days. Three groups of the rats were killed and the brains were quickly removed for frozen sections and then performed with conventional HE and immunohistochemistry staining. And protein samples were prepared from brain and the hippocampus tissues of the three groups to detect the level of the ChAT protein by Western blot.
RESULTSThe experimental rats turn left or right when continuously stimulation in the bilateral BC regions with electric pulse. HE staining showed no significant damage around electrodes in the cerebral cortex. Compared with the control and blank groups, the ChAT positive rate in the brain section in the experimental rats was significantly high by immunohistochemistry assay; the level of the ChAT protein in the rats given the electrical stimulation increased.
CONCLUSIONTurnings performance of the rat could be initiated hy electrical stimuli in the BC region. Expression of ChAT is significantly higher in the BC regions of rat under electrical stimulation, suggesting that acetylcholine might be associated with signal transmission between senses and movement behavior in the nervous central system.

OBJECTIVETo study the feasibility and authenticity of repairing alveolar defects in alveolar cleft patients with osteoinduction active material (OAM) in clinic.
METHODSTwenty-seven cases of alveolar defect chosen from clinic were divided into two groups (test group and control group). For test group (12 cases), OAM was transplanted to repair the alveolar cleft. For control group (15 cases), autogenous ilium cancellous bone were transplanted into the defect region to repair alveolar cleft. At 6 months after operation, CT and three-dimensional reconstruction were used to observe alveolar appearance, and the effect and clinical success rate of recover alveolar cleft by using different repair material were compared.
RESULTSIn the 27 cases, all the maxillary continuity was restored except two of test group and two of control group. There was no significant difference between test group and control group regarding the clinical success rate of the alveolar cleft repair (P = 1.000).
CONCLUSIONOAM was used to repair the alveolar cleft that can result in new bone formations and the burgeon of canines from the bone grafted areas. There is no significant difference between OAM and autogenous ilium cancellous bone regarding the effect of the alveolar cleft repair.

OBJECTIVETo investigate the association between the expression of galectin- 3 protein and peritoneal metastasis in gastric cancer.
METHODThe expressions of galectin- 3 was detected in matching- samples including primary gastric cancer lesions,lymph node metastases,peritoneal metastases and paratumor normal tissues by immunohistochemistry. All specimens were gained from 35 patients who had synchronous peritoneal metastasis from gastric cancer.
RESULTSThe over- expression of galectin- 3 was observed in 97% (34/35) of the gastric cancer lesions, the peritoneal metastases and the lymph node metastases,whereas in 14% (5/35) of paratumor normal tissues. There were significant differences in the expression of galectin- 3 between paratumor normal tissues and the gastric carcinoma lesions,peritoneal metastases and lymph node metastases (P< 0.05),but there were no significant differences among the gastric cancer lesions,the peritoneal metastases,and the lymph node metastases (P> 0.05).
CONCLUSIONThe expression of galectin- 3 in gastric cancer lesions can be used as a biological marker of peritoneal metastasis from gastric cancer before operation and as a prognostic factor of gastric cancer.
