The complete coding sequences of Eya gene family was amplified by standard PCR fromhuman tissues or cells cDNA library.The product of PCR was cloned into the eukaryotic expression vector pcDNA3-FLAG,generating pcDNA3-FLAG-Eya1～4.Thenhuman embryo kidney 293T cells were transfected with the recombinant plasmids and the expression of Eya genes were identified by Western blot.Transcriptional assay using a reporter containing myogenin enhance factor indicated that expression of Eya cooperation with Six in 293T cells affected the Myogenin gene expression.The expression vectors of Eya genes were constructed and confirmed by restriction enzyme digestion and DNA sequence analysis.Transcriptional assay using a reporter containing myogenin enhance factor indicated that expression of Eya in coordination with Six in 293T cells stimulated the Myogenin gene expression.Eya proteins are transcriptional activator of Six and can improve the activity of myogenin promoter.

OBJECTIVESTo screen differential proteins in serum from hepatocellular carcinoma (HCC) patients by Proteomic Technology and to purify and identify them.

METHODSSurface enhanced laser desorption Ionization time of flight-mass spectrum (SELDI-TOF-MS) was employed to screen differential proteins in serum from 33 HCC patients and 33 control cases, and then to purify and identify them using isoelectric precipitation, Tricine sodium dodecyl sulphate polyacrylamide gel electrophoresis (Tricine-SDS-PAGE) and high performance liquid chromatography tandem Mass Spectrum (HPLC-MS).

RESULTS65 protein peaks in the range of relative molecular weight from 2,000 to 10,000 were found significant difference (P less than 0.05) between the patient group and control group. Based on these differential protein peaks, diagnostic model for HCC detection was established and its sensitivity and specificity were 100% and 96.97% respectively. Proteins with 8,706.5 and 8,579.2 relative molecular weights (the t value was 2.562 and 2.783 respectively, and P value was 0.013 and 0.015 respectively) out of the 65 differential proteins were purified and identified, and then recognized as Apolipoprotein AII (Apo AII).

CONCLUSIONApo AII is probably a differential protein of HCC and maybe related to the pathogenesis of HCC.

As an important link during the whole operation process of acupuncture, it is very necessary to launch quantity study closely related to acupuncture finger force in the acupuncture quantity study. After retrieval of related literatures on finger force during acupuncture in recent 20 years, it was found out that although some exploration on acupuncture finger force had been made, it was scattered and had no deep research, which pointed out it was a weak link in the acupuncture quantity study. So study of finger force should be paid attention to in acupuncture-moxibustion field, the level of theoretical and experimental research and development of measuring instrument on acupuncture finger force should be strengthened, the application of instrument should be expanded in teaching and scientific research areas, which could promote the modernization and internationalization of acupuncture and moxibustion better and faster.

OBJECTIVETo investigate the effect of sulindac on proliferation and apoptosis of human gastric cancer BGC-823 cells and its antineoplastic mechanisms.

METHODSHuman gastric cancer BGC-823 cells were incubated with sulindac at various concentrations and for different times. Morphological changes of BGC-823 cells were observed under an inversion microscope. MTT colorimetric assay was used to examine the effect of sulindac on the proliferation of BGC-823 cells. Flow cytometry was used to determine the cell cycle distribution and apoptosis. Transmission electron microscopy was performed to examine cell apoptosis morphology. Immunohistochemical staining was used to detect the expressions of COX-2, bcl-2 and ki-67 in the cells.

RESULTSsulindac induced morphologic alterations in BGC-823 cells, inhibited cell proliferation, increased the proportion of cells in G0/G1 phase and decreased the proportion of cells in S phase, induced apoptosis of BGC-823 cells, and decreased expressions of COX-2, bcl-2, ki-67 in the cells. All the effects were in a time- and dose-dependent manner (P < 0.05). Some characteristic morphologic features of apoptosis were revealed by transmission electron microscopy.

CONCLUSIONsulindac may inhibit the growth of gastric cancer BGC-823 cells in vitro and the anti-tumor mechanism may be related to changes in cell cycle distribution, induction of apoptosis and inhibition of expression of COX-2, bcl-2, and ki-67.

OBJECTIVESTo study the acupoint specificity through the comprehensive evaluation of the acupuncture effect on rat model with the middle cerebral artery occlusion (MCAO).

METHODSDuplicated MCAO model by Zea-longa's thread ligation was assessed by Zausinger's six-point method, and rats with 1-3 scores were chosen to be grouped. According to the randomized and controlled principle, rats were divided into 6 basic control groups (including normal group, sham group, model control group, model group without intervention, Nimodipine group, lateral-to-Renzhong group) and 6 acupuncture groups [including Neiguan (PC6) group, Weizhong (BL40) group, Chize (LU5) group, Sanyinjiao (SP6) group, Renzhong (DU6) group and non-acupoint group]; in each acupoint or non-acupoint 9 different parameter combinations were respectively set by orthogonal intersection method. There were in total 60 groups, and each group had 12 rats. The rats were treated by acupuncture with the lifting-thrusting manipulation every 12 h, in total 6 times. Indices of neurobehavioral scores, cerebral blood flow, infarction rate, microcirculation, and light microscope, etc. were measured. In order to comprehensively evaluate the acupuncture effect to research the specificity of acupoint, a cluster analysis was made with SPSS17.0 for the comprehensive effect scores of the samples computed according to the comprehensive evaluation models, and then sorting and classification were made for the comprehensive effect scores.

RESULTSIn the acupuncture groups every acupoint had different therapeutic effect due to different acupuncture parameter combinations; among the acupuncture groups the orders of curative effect were as followings: Neiguan group was of exceptional result, Weizhong group and Sanyinjiao group were of valid results in upper level, Chize group and Renzhong group were of valid results in lower level, and non-acupoint group was of invalid result; the therapeutic result of acupoint group was superior to non-acupoint group; and the curative effect of acupuncture group was also superior to basic control group.

CONCLUSIONThe acupoint has the specificity of acupuncture effect, and the acupoint specificity is relative.

OBJECTIVETo investigate the influence of acupuncture parameters on the acupuncture effect through the cluster analysis in Wistar rat model with middle cerebral artery occlusion (MCAO).

METHODSDuplicated MCAO models by Zea-longa's thread ligation and chose rats with 1-3 scores assessed by Zausinger's six-score method to be grouped. The rats were divided into 6 basic control groups [(including a normal group, a sham group, a model control group, a model group without intervention, a Nimodipine group, a lateral-to-Renzhong (DU6) group] and 6 acupuncture groups [a Neiguan (PC6) group, a Weizhong (BL40) group, a Sanyinjiao (SP6) group, a Chize (LU5) group, a Renzhong (DU6) group and a Feixue (non-acupoint) group]. In the acupuncture groups, for every acupoint or needling site, 9 different parameters [2 factors (frequency and time) and 3 levels (180, 120, and 60 cpm of the frequency and 5, 60, and 180 s of the time)] were set respectively by the orthogonal intersection method, in total 54 groups. The rats were treated by acupuncture with a lifting-thrusting manipulation once every 12 h, in total 6 times. Neurobehavioral scores, cerebral blood flow, infarction rate, microcirculation, light microscopy, etc. were measured. The factor analysis was first applied to get the comprehensive effect scores of the samples in the acupuncture groups and then by which the cluster analysis was made with the statistical software of SPSS17.0.

RESULTSFor the Neiguan (PC6) group, the exceptional results of acupuncture comprehensive effect were parameters 7, 8, 9, 10; the valid results were parameters 2, 3, 4, and the invalid were parameters 5, 6. For the Weizhong (BL40) group, the exceptional results were parameters 2, 4; the valid results were parameters 3, 5, 6, 7, and the invalid were parameters 8, 9, 10. For the Chize (LU5) group, the exceptional results were parameters 7, 8; the valid results were parameters 3, 4, 5, 6, 9, 10; and the invalid was parameter 2. For the Sanyinjiao (SP6) group, the exceptional results were parameters 4, 6; the valid results were parameters 2, 3, 5; and the invalid were parameters 7, 8, 9,10. For the Renzhong (DU6) group, the exceptional results were parameters 3, 4, 6, 7, 9, 10; the valid results were parameters 2, 5; and the invalid was parameter 8. For the Non-acupoint group, the exceptional result was parameter 10; the valid results were parameters 2, 3, 4, 7, 9; and the invalid were parameters 5, 6, 8.

CONCLUSIONSFor each meridian acupoint, different acupuncture parameters could consequently get a different acupuncture effect; each meridian acupoint had the most suitable or optimal acupuncture parameters; acupuncture parameters might be the main factors impacting on acupuncture effect.
