AIM:To investigate the effect of the N-terminal 24-amino acid (N24) overexpression in p55γre-gulatory subunit of phosphatidylinositiol 3-kinase ( PI3K) on the cell adhesion of human gastric carcinoma cell MGC 803. METHODS:MGC803 cells, which stably expressed GFP-N24 fusion protein and GFP alone , were generated by transfec-tion with pEGFPN-24 plasmid and control plasmid pEGFP-C1, respectively.The morphological change of the cells was ob-served under inverted microscope .The expression of GFP-N24 fusion protein was detected by Western blot .The adhesion of the cells was determined by cell adhesion assay .The effects of GFP-N24 fusion protein on the expression of E-cadherin andβ-catenin were analyzed by Western blot .The expression and secretion of matrix metalloproteinase 9 (MMP9) and u-rokinase-type plasminogen activator ( uPA ) in the MGC803 cells were detected by gelatin zymography .RESULTS:MGC803/GFP-N24 cell line steadily expressed GFP-N24 fusion protein and MGC803/GFP cell line steadily expressing GFP were successfully established , but the expression of fusion protein GFP-N24 was lower than that of the control protein GFP.The morphological changes of the transfected cells from paving stone to fibroblast cell form after gene transfection , and the cytoplasm secretory granules were increased significantly .The cell adhesion to fibronectin and collagen decreased after GFP-N24 transfection .GFP-N24 fusion protein increased the expression of cell adhesion molecule E-cadherin and de-creased the wnt signal pathway molecule β-catenin in the MGC803 cells.However, it did not affect the expression and se-cretion of tumor metastasis-related proteins MMP9 and uPA.CONCLUSION:Overexpression of N24p55γinhibits cell ad-hesion by influencing the expression of E-cadherin and β-catenin in the MGC803 cells.

Objective To investigate the association of the gene polymorphism of plasminogen activator inhibitor 1 (PAI 1) with the cerebral infarction and recurrent cerebral infarction (RCI). Methods The plasma PAI 1 activity, by means of chromgenic substrate assay, and the sequence polymorphisms of 4G/5G in promotor region and (CA)n dinucleotide repeats in the 4th intron of PAI 1 gene, by amplified fragment length polymorphism assay, were measured in 50 patients with first ever cerebral infarction (FCI), 45 patients with RCI and 60 healthy controls.Results The plasma PAI 1 activities in both FCI patients (1.13?1 1 AU/ml) and RCI (1.13?0.150 AU/ml) were remarkably higher than that in the controls (0.7?0.25 AU/ml) (both P

Objective To discuss clinical and cytological features of cerebrospinal fluid (CSF) in meningeal careinomatosis (MC). Methods The data of clinic, imaging and CSF of 59 inpatients with MC were analyzed retrospectively. Results There were 91.5% (54 cases) of middle and elder aged in the group. Most of patients were at acute or subacute onset . Condition developed fast. 55 cases (93.2%) didn't feel fever primarily. Intracranial hypertension of headache (57 cases ),vomitted(45 cases ) and disc edema(21 cases ) ect. were predominant features. In 32 cases (54.2%), cranial nerves were involved. Optic never and abducent never damage appeared the most frequently. Oculomotor never, facial nerve and vestibulocochlear nerve were in the next. All of 59 cases had meningeal irritation sign, among them 31 cases (52.5%) with obvious sign. Tumor cells in cytological examination of CSF were found in all of 59 cases. Conclusions The clinical manifestations of MC has some certain features. Diagnosis of MC still relay on finding tumor cells in cytological examination of CSF.

Object To investigate the structure, physicochemical properties and anticancer activity of three kind of glycyrrhizic acid aniline platinum complex compounds. Methods Using the FT IR methods, elementary analysis and X ray diffraction, the physicochemical properties of the tested drugs were determined; by means of MTT test the inhibitory effects of the drugs on human tumor cell growth were examined, with hematopoietic cell K 562 , melanoma cell LiBr and liver cancer cell 7721 as the model of anticancer activity. Results Experimental values of elemental analysis of three complex compounds tally with the theoretically calculative values. The infrared spectroscopy showed that the functional group location agreed with the structure. The X ray diffraction exhibited that this type of the compounds was monoclinic system. Conclusion The experimental results show that the anticancer activity of the test complex compounds is related to their concentration and ligands. Magnetic field treatment has significant influence on anticancer activity of this type of compounds.

Objective To evaluate the reproducibility of the three-dimensional volume measurement and two-dimensional measurement of pulmonary nodule volume with 64-detector computed tomography.Methods Thirty-three patients with pulmonary nodule who underwent the examination with 64-detector spiral CT(Lightspeed VCT,GE) were included,in whom sixty solid nodules with the diameter less than 3 cm were found.There were 18 women and 15 men.CT images were analysed by two radiologists,respectively,the volumes of pulmonary nodules were measured with ALA software continuously,and two-dimensional measurements which were separated a month apart were also done in the GE AW4.2 workstation independently.Intra-and inter-reader agreement were determined by using Bland and Altman method and the Spearman correlation coefficients,the variability between three-dimensional measurements and two-dimensional ones were identified.Results 57 nodules in 60 were successfully segmented and 3 were segmented incorrectly or unsuccessfully,the ratio of successful segmentation was 95%.Three-dimensional measurements between two readers were highly correlated with r of 0.998,and the r was 0.974 in the two-dimensional measurements.The difference between the two correlation coefficients was significant.The three-dimensional measurements between two readers had completely agreed with each other for nodules that of the diameter

Objective To investigate one year survival rate and life quality of patients with non-small cell lung cancer(NSCLC)treated by different arms.Methods One hundred and seventy-nine cases NSCLC patients from January 2013 to December 2014 were selected from the Third Hospital of Tanshan and followed-up,including 57 cases with surgical treatment,70 cases with the use of Navelbine plus cisplatin,52 cases with dendritic cells(DC)and cytokine induced killer cells(CIK)immune based therapy(DC/CIK)treatment.After one year period of radiotherapy and chemotherapy,the SF-36 questionnaire was used to investigate the quality of life of the surviving patients,and the quality of life was assessed from three aspects of the physiological,psychological and social functions.To quantify the quality of life score,the 100 percentage grading system was adopted,logistic regression analysis was used to adjust the influence of age and gender on survival rate,and the data were analyzed by SAS 9.2 statistical software package.Results One hundred and seventy-nine subjects were included in this study,by the end of follow-up on December 2015,there were 119 cases survived,the survival rate was 66.5％(119/179).Survival rate of surgical operation group,DC/CIK group and chemotherapy group orderly decreased(82.5％(47/57),76.9％(40/52)and 45.7％(32/70),P＜0.01).After adjusting age and gender impact,multiple logistic regression model showed that DC/CIK group survival rate was 3.96 times higher than the pure chemotherapy group(95％CI=1.78-8.80),surgical operation group was 5.58 times higher than simple chemotherapy group(95％CI=2.44-12.79).There were no significant differences between DC/CIK group and surgical operation group on physical disease,health status,emotional intelligence,mental health and social function,no significant difference(P＞0.05),but the chemotherapy group was lower(P＜0.05);physiological function in the chemotherapy group,operation group and DC/CIK group showed an increasing trend(P＜0.05).Conclusion The one year survival rate of NSCLC patients treated by different arms is 66.5％,and the life quality of patients with biological immune therapy method is better.

Objective To analyze the changes of leptin and adiponectin levels in serum of patients with diabetic retinopathy and investigate their chnical significance in diabetic retinopathy (DR).Methods One hundred and twenty-one patients with type 2 diabetes mellitus as the case group who hospitalized from Nov.2012 to Nov.2013.Among the patients,41 cases of non-DR,40 cases of nonproliferative-DR,40 cases of proliferativeDR.Forty healthy were served as the control group.The levels of leptin and adiponectin in serum were detected by Enzyme-Linked Immuno Sorbent Assay (ELISA).Results The overall levels of leptin in case group was (15.25 ± 4.70) μg/L,significantly higher than the control group ((6.15 ± 1.70) μg/L; t =-11.696,P ＜0.01)).The level of adiponectin in case group was (7.39 ± 1.92) mg/L,lower than the control group ((11.10 ± 1.46) mg/L; t =11.216,P ＜ 0.01).Moreover,the levels of leptin increased successively from (10.91 ±1.21) μg/L in NDR,(15.22 ±3.75) μg/ L in NPDR and (20.50 ±3.70) μg/L in PDR.While,the adiponectin levels decreased from (9.61 ± 1.35) mg/L in NDR,(7.11 ± 1.18) mg/L in NPDR and (5.34 ± 1.36) mg/L in PDR respectively.And the differences between the groups were significant(F =149,542,291,550;P ＜0.05).The levels of leptin and adiponectin in serum showed a negative correlation (r =-0.662,P ＜0.01).Condusion Levels of leptin and adiponectin in serum associate with DR,and both of them might be the important indexes for the prediction and curative effect evaluation of DR.
