Objective:To screen the binding peptide against adenovirus type 7(Ad7) and evaluate the relevance with the ade-novirus receptor .Methods:Binding peptide against Ad 7 was screened by panning the phage display 12 peptides library .The antibody against the selected peptide was prepared and was used to study the binding to the membrane by immunofluorescence technique .Re-sults:Using Ad7 as the target protein , GTS09 peptide was selected from the phage display 12 peptides library by biopanning .GTS09-phage complex could significantly bind Ad 7, with the affinity constant up to 1.93 ×1010 L/mol;at the same time, immunofluorescence showed that antibody of GTS09 could specifically bind to membrane of 293 cell.Conclusion: Antibody against GTS09 peptide could specifically bind to membrane of 293 cell,which shows that the peptide may presumably have homology with the cell receptors of Ad 7.

AIM: To investigate lipoprotein lipase gene HindⅢ polymorphism and its relationship with serum lipids and apolipoprotein, serum HDL subclasses in patients with hyperlipoidemia. METHODS: Lipoprotein lipase gene HindⅢ polymorphism was assayed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The subclasses of serum HDL in 152 hyperlipoidemia patients and 128 healthy subjects were determined by two-dimensional gel electrophoresis conjunction with immunodetection method. RESULTS: H+H+ genotype and allele H+ in hyperlipoidemia and control groups were both the highest. In hyperlipidemia group, H+H+ genotypes tended to be higher than that in control group, while H+H- and H-H- genotypes were significantly lower (P

Objective To study the spinal neurocyte apoptosis and the changes of p53 in chronic fluorosis rats,and the improvement after drinking no fluoride water.Methods One hundred twenty Wistar rats were divided into 4 groups by random number table method according to body mass,30 rats in one group fed with high concentration NaF water (200 mg/L) to make fluorosis model and classified as high fluoride group;other 30 rats were fed with distilled water as control group;another 30 rats were fed with high concentration NaF water (200 mg/L) for 12 weeks,then fed with distilled water for 12 weeks and classified as defluorination group;the rest 30 rats were classified as defluorination control group.The content of fluoride in urine was tested after the 4th,8th,and 12th weeks.Then the content of fluoride in urine of defluorination group and defluorination control group was tested.The high fluoride group rats and control group rats were killed after 12th week.Defluorination group rats and defluorination control group rats were killed after 24th week.Their spinal cord was collected.The expression of p53 protein in spinal cord was detected by immunohistochemistry and Westem blotting.Apoptosis of the neurocyte was quantitatively analyzed by flow cytometry (FCM).Results By FCM,apoptosis of neurocyte was increased in both high fluorosis group rats and defluorination group rats compared with those in control group rats [(3.36 ± 0.71)％ vs.(0.78 ± 0.65)％;(3.47 ± 0.56)％ vs.(0.83 ± 0.64)％,t =14.680,17.003,all P ＜ 0.01)],but no difference was found between these two groups [(3.47 ± 0.56)％ vs.(3.36 ± 0.71)％,P ＞ 0.05)].Immunohistochemistry and Western blotting revealed that p53 expression in spinal cord of high fluorosis group rats was increased compared with those in control group rats (422.69 ± 12.35 vs.177.82 ± 14.16;253.37 ± 10.42 vs.87.14 ± 7.39,t =77.212,72.988,all P ＜ 0.01).And p53 expression in spinal cord of defluorination group rats was increased compared with those in control group rats (418.75 ± 11.84 vs.163.47 ± 8.57;248.29 ± 10.23 vs.98.74 ± 11.52,t =95.663,53.167,all P＜ 0.01).But the differences were not statistically significant (418.75 ± 11.84 vs.422.69 ± 12.35;248.29 ± 10.23 vs.253.37 ± 10.42,t =1.261,1.906,all P ＞ 0.05).Conclusions There is apoptosis of neurocytes in the spinal cord of chronic fluorosis rats;overexpression of p53 probably plays an important role in the mechanism of damage induced by excessive fluorine.Apoptosis can not be recovered after defluorination for a short time,and persistent overexpression of p53 may be one of the reasons that apoptosis of neurocytes in the spinal cord can not decrease.

Objective To investigate the personality traits, anxiety and depression in patients with leukemia. Methods A cross-sectional survey was performed in 120 patients with leukemia and 118 age and gender-matched controls. Personality was assessed using the Type A Behavior Pattern Questionnaire (TABPQ). Emotion was ascertained using the self-rating anxiety scale (SAS) and self-rating depression scale (SDS). The relationship between personality type A and anxiety and depression was evaluated by Pearson correlation analysis. Results The prevalence of personality type A was significantly higher in patients with leukemia than healthy controls [71.67 % (86/120) vs. 30.51 % (36/118), P< 0.01]. Patients with leukemia also had higher prevalence of anxiety and depression compared with healthy controls [36.67%(44/120) vs. 9.32%(11/118), P< 0.01; 29.17 % (35/120) vs. 5.93 % (7/118), P< 0.01]. Pearson correlation analysis showed that time-hurry (TH) and competition-hostility (CH) of personality type A correlated positively with anxiety (r=0.292, r= 0.277, respectively; both P< 0.05). Conclusion TH and CH of personality type A are associated with anxiety in leukemia patients.

BACKGROUND:Some scholars have found that cervical vertebral body bone trabecula was reduced,became thin,even perforated in old patients with osteoporosis.Whether this change will induce cervical vertebral body deformation,and what relationship to the onset of cervical syndromeOBJECTIVE:To study the relation of cervical spondylotic myelopathy and osteoporosis by measuring and comparing.METHODS:A totaI of 40 subjects with normal lumbar vertebra density and without cervical spondylosis were enrolled as control group,averagely 32 5 years.A total of 30 patients with cervical spondylosis served as cervical spondylosis group,averagely 43.6 years.Totally 46 patients with cervical spondylosis and osteoporosis served as combined with osteoporosis group,averagely 58.6 years.116 subjects underwent radiograph Height and sagittal diameter of the vertebral body ratio of height to sagittal diameter of the vertebral body.and ratio of sagittal diameter of cervical canal/vertebra body were measured.RESULTS AND CONCLUSION:Compared with the control group.vertebral height was decreased.and sagittal diameter became longer(P＜0.05),and the ratio of sagittal diameter of cervical canal/vertebra body became smaller(P＜0.05)in the combined with osteoporosis group.Vertebral body deformation was characterized by decreased vertebral height and prolonged sagittal diameter became flat.Results suggested that osteoporosis induced cervical vertebral deformation,correlation between osteoporosis and cervical spondylosis,which may be a factor for cervical spondylosis development.
