Objective:To investigate the expression of AEG-1 gene in NSCLC and its clinical significance. Methods:Selected our hospital cardiothoracic surgical resection of 83 cases of postoperative cancer tissues of NSCLC patients and 20 paracancer to study, immunohistochemical staining was used to detect the expression level of AEG-1 protein in two groups,the clinical and pathological of AEG-1 protein in patients with NSCLC was analyzed. Results:NSCLC tissues AEG-1 protein expression 46 cases ( 55. 42%) was sig-nificantly higher than 2 cases ( 10. 00%) of paracancer ( P<0. 05 ) . The high expression of AEG-1 protein in NSCLC tissue was significantly correlated with T stage,N stage and distant metastasis (P<0. 05),the relationship of AEG-1 between the age,sex,and dif-ferentiation degree of the patients was not significant ( P>0. 05 ) . AEG-1 high expression of NSCLC in patients with a median survival time of 15. 0 months was significantly lower than that of 19. 0 months (log-rankχ2=4. 119 P<0. 05,) in patients with low expression of AEG-1. Conclusion:AEG-1 gene expression has been up-regulated in NSCLC tissue,which was related to the clinical stage and distant metastasis of the patients.

Objective To observe the effect of H shaped decalcified bone grafting on spinal fusion and anti conglutination by posterior approach and to evaluate its values in the application in spinal posterior approach surgery. Methods Total laminectomy was performed on 23 cases of severe spinal stenosis and 31 cases of intraspinal tumor for decompression. Thorough decompression of the nerve roots was performed on the former following total laminectomy while exploration and excision of the neoplasm were done on the latter. Then, H shaped decalcified bone grafts were inlaid between spinous processes and transverse processes to cover the lamina defection and overlap the adjacent segments in all cases. At last, the spinal internal fixation or plaster external fixation were used to stabilize vertebral segments according to the economic status of patients. The average time of follow up was 21 months (18～31 months). Results All patients got successful segmental spinal fusion within 8 months. Clinical symptoms were obviously alleviated in 43 cases at the end of follow up but symptoms recurred 12 months after operation in other 11 cases(all were tumor patients). Conclusion H shaped decalcified bone graft is valuable in spinal fusion and anti conglutination in spinal posterior approach surgery.

Objective To study the correlation of HBV infection pretransplantation and posttrans-plantation and HCMV recurrence after liver transplantation (LT). Methods We reviewed historical patient medical records of LT patients in recent two years in our hospital. All the patients were divided into HBV in-fection group and a control group based on a peripheral blood HB antigen assay before LT. The HBV infec-tion group was divided into HBV reactive infection group and HBV non-relapse group. HCMV antigen pp~65 was detected by immunohistochemical methods. HB antigens and antibodies were detected by time-resolved fluorescence immunoassay, and liver enzyme levels were detected by conventional methods. Results Com-paring two groups of patients, pp65-positive rates of LT patients with HBV infection and control group pa-tients were 84.3% and 57.9% respectively (P=0.024). While in HBV recurrence infection group and non-recurrence infection group, the incidences of HCMV recurrence were 90.9% and 83.3% (P=0.843). The changes in the liver transaminases level in both groups have no statistical significance (P>0.05). Conclusion Pretransplantation HBV infection may increase the incidence of HCMV recurrence. Posttrans-plantation HBV reactive infection, however, may not increase the incidence of HCMV reactive infection. Meanwhile, compare with either HBV infection or HCMV infection alone, co-infection may not serious in liv-er enzymes levels.

Objective To evaluate the application value of real-time three-dimensional transesophageal echocardiography (RT-3DTEE) for the risk assessment of unusual atrial septal defect (ASD) in clinic therapy.Methods Accurate assessment before operation was conducted in 57 cases of patients with unusual ASD by two-dimensional transthoracic echocardiography (2DTTE),two-dimensional transesophageal echocardiography (2DTEE) and RT-3DTEE.The ultrasound manifestations were observed.And the guidance in clinic therapy were compared.Results The shape and number can be displayed clearly by 2D-TTE and 2D-TEE in 46 of 57 eases.Another 11 cases were diagnosed as irregular or two holes possibly.RT-3DTEE can help to observe the morphology and quantity of ASD visually and comprehensively in all cases.There was no statistical difference among 2DTTE,2DTEE and RT-3DTEE for the measurement of right atrium end-systolic transverse diameter (RATD),left atrium end-systolic transverse diameter (LATD),right ventricular end-diastolic diameter (RVDD) and left ventricular end-diastolic diameter (LVDD;all P＞0.05).The statistic difference for the diameter of atrial septal defect (ASDD) was found between 2D-TEE and 2D-TTE (P＜0.05) and RT-3DTEE and 2D-TTE (P＜0.05).There was no statistical difference among 2D-TEE,2DTTE and RT-3DTEE for the measurement of residual boundary condition of superior vena cava,aorta side and the top side of the atrium (all P＞0.05),whereas significant difference was found in measuring the residual boundary condition of inferior vena cava (F=50.39,P＜0.001).There were statistic differences between 2DTEE and 2DTTE,RT-3DTEE and 2DTTE,RT-3DTEE and 2DTEE (all P＜0.05).The clinic therapy can be directed by RT-3DTEE in all 57 cases.The diagnosis of 5 cases was failed by 2D-TTE,and 2 cases was failed by 2D-TEE.Conclusion Abundant image information can be offered by RT-3DTEE which plays an important role in the risk assessment of unusual atrial septal defect.

Objective To investigate JC virus(JCV) infection in kidney transplant recipients and its influence on graft function and also initially explore JCV infection factors. Methods A total of 49 kidney transplant recipients and 24 health examination persons were enrolled in our study, JCV DNA was measured using nested qualitative polymerase chain reaction assays of urine, while CMV DNA was measured by common qualitative polymerase chain reaction assays of urine. JCV infection factors, such as age, male, immunosuppressive therapy, cytomegalovirus(CMV) infection were analyzed by Binary Logistic Regression, and glomerular filtration rate(GFR) was selected as a index of kidney function and the difference of GFR between JCV-infected and non-infected patients was compared using t test. Results JCV was detected in 42.9% of kidney transplant patients and 4.2% health examination persons. CMV infection and Pred + MMF + CsA triple immunosuppressive regimen were found to be the risk factors of JCV infection. No difference of GFR was observed between JCV infected and non-infected patients (86.470 ± 29.990 and 84.060 ± 33. 729 for each; t =0. 259, P =0.797). Conclusion JCV is frequently detected in kidney transplant recipients. CMV infection and using of Pred + MMF + CsA triple immunosuppressive regimen can significantly increase the risk of JCV infection. While, graft function was not influenced by JCV infection in kidney transplant patients.

Objective To estimate brain grey matter volume changes and location of abnormal brain regions cerebrum in early stage of bipolar disorder I (BD),in order to provided objective basis for diagnosing early stages BD.Methods 1 7 cases of BD with duration less than 2 years and 1 7 normal controls were recruited in this study.The volumetric difference of grey matter between two groups were analyzed by using voxel-based morphometry(VBM)software.Statistical threshold was voxel> 100,P <0.001 (uncor-rected).Results Compared to the normal controls,the grey matter volume of BD patients decreased in the left dorcial anterior cingu-late cortex(ACC),left insular,right sub-genu ACC,left superior temporal cortex,bilateral hippocampus-parahippocampus-amydala and left posterior lobe of cerebellum(P <0.001).Conclusion The grey matter volume of early stage BD patients is decreased,main-ly locating in the bilateral limbic system,the superior temporal gyrus and the cerebellar cortex,which probably is the morphological appearance of pathomechanism in early stages of BD.

Background Researches showed that elevatory blood glucose level results in long-term damage of cells and tissue,or metabolic memory phenomenon,and manipulation of hyperglycemic memory is a good approach in the prevention of diabetic complications.However,its mechanism is not clear.It is speculated that the pathogenesis of diabetic retinopathy (DR) in diabetic patients may be associated to related mechanisms.Uncoupling proteins (UCPs) can decrease the production of reactive oxygen species (ROS),which may be related to DR.Objective This study was to explore the association between DR and the single nucleotide polymorphisms (SNPs) of UCP genes in Chinese Han population with type 2 diabetes.Methods A cross-sectional study was performed.This study was approved by Ethic Committee of Affiliated First Hospital of Shanghai Jiao Tong University and complied with Declaration of Helsinki,and written informed consent was obtained from each subject prior to any medical examination.One thousand eight hundreds and seventy-five patients with type 2 diabetes mellitus were enrolled in Xinjing district of Shanghai city by cluster sampling from November 2014 to January 2015.The demographic and medical baseline characteristics,ocular examination and laboratory tests were obtained and periphery blood of 2 ml was collected for extraction of DNA.Eight tag SNPs of UCP1,three tag SNPs of UCP2,and seven tag SNPs of UCP3 were selected as marker locus for the detection of genotype by Sequenom Mass ARRAY.Matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry platform were used for genotyping.Hardy-Weinberg equilibrium (HWE) analysis,allele and genotype frequencies,haplotype analysis,and association tests for DR and SNPs were performed by SAS and SHEsis software.Results A total of 530 DR patients were checked out from 1 875 subjects with type 2 diabetes mellitus,with the detection rate of 28.27％.rs660339 locn of UCP2 gene and rs1626521,rs668514 locus of UCP3 gene appeared to have low detectable rates,and the secondary allele base frequency of rs632862 in UCP2 gene was ＜0.01 and rs15763 of UCP3 gene was unmatched with HWE,therefore,these locus analysis was not included.In 13 SNPs locus included in the analysis,only 2 SNPs of UCP1 gene were related to DR.Compared with the non-diabetic retinopathy (NDR) patients,the G allele frequency of rs10011540 was increased (P =0.03,OR =1.31,95 ％ confidence interval[CI] =1.03-1.67,and T allele frequency of rs3811787 was decreased (P=0.04,OR=0.86,95％ CI=0.75-0.99) in DR patients.Genotyping detection showed that the C/C and A/A frequencies of rs3811790 in UCP1 gene were significantly more and C/A frequency was less in DR patients than those in NDR patients (all at P＜0.01).The logistic regression analysis indicated an association of SNPs of rs10011540 and rs3811787 with DR independent from glucose and disease duration.Conclusions The SNPs of rs10011540 and rs3811787 locus in UCP1 gene are associated with DR in Chinese type 2 diabetes patients.
