Objective To investigate the influence of IVIG on immunologic function and cytokines levels in children with EV71 infection associated high-risk pulmonary hemorrhage. Methods According to the inclu-sion criteria , 64 children were enrolled and randomly divided into two groups: 39 cases in the IVIG treatment group and 25 cases in the general treatment group. The alternations of blood and immune cytokine markers before and after treatment were detected in the patients. Results (1) Before treatment, the peripheral blood T cells, TH and B cells in the IVIG group were higher than those in the general group , but the peripheral blood IgA was lower than that in the general group(P < 0.05); (2) In the IVIG group, the NK cells and IgG increased and T cells, TH cell and B cells significantly decreased after receiving IVIG therapy (P < 0.05); (3)No significant difference was observed in the levels of IL-6 and IL-10 in the two treatment groups before treatment. However , after IVIG treatment, IL-6 and IFN-γ levels reduced, IL-10 level increased (P < 0.05). After the general treat-ment, no significant difference was found in levels of IL-6,IL-10 and IFN-γ in peripheral blood (P > 0.05). Conclusion Disorders of cellular immunity and humoral immunity appeared in children with EV71 infection-re-lated high-risk pulmonary hemorrhage. It has clinical value to use IVIG timely to regulate the immune disorder.

Objective To investigate the relationship between growth inhibiting effect of arsenic trioxide(As_2O_3) and phosphorylation of P27kip threonine residue 187(P27T187) in human hepatocellular carcinoma(HCC) cell line SMMC-7721.Methods SMMC-7721 were treated for 72 h with 2 ?mol/L As_2O_3.The cell growth inhibition was detected by cell counting and the cell cycle was detected by flow cytometry(FCM).The expression and localization of P27,T187 phosphorylated P27(p-P27T187) were detected by Subcellular Fractionation,Western blot and immunoflurescence.Results As_2O_3 significantly inhibited the proliferation of SMMC-7721 cell and cell cycle was arrested in G2/M.A significant decrease in p-P27T187 expression and a reciprocal increase in P27 expression were found in 2 ?mol/L As_2O_3-treated SMMC-7721 cell.Meanwhile,As_2O_3 decreased the protein levels of Cdk2 and cyclinE.The location of P27 was transferred from cytoplasm to nuclei and the expression of p-P27T187 was decreased in nuclei.Conclusion As_2O_3 inhibits the phosphorylation of P27T187,thereby promoting P27 accumu-lation in SMMC-7721 cell nuclei,inducing cel1 cycle arrest and growth inhibition.

Objective To investigate the expression of C-JUN activation domain binding protein 1(JAB1)and its relationship with expression of P27 protein in human hepatocellular carcinoma(HCC),and to determine whether JAB1 is associated with clinicopathological parameters and prognosis of HCC.Methods Immunohistochemical analysis was performed to investigate the expression of JAB1 and P27 in 76 cases of HCC and adjacent nontumorous tissues.Fresh tumor tissues and their adjacent nontumorous tissues from 8 cases of HCC were collected for Western blot and immunoprecipitation assays.Results The expression of JAB1 in HCC was significantly higher than that in adjacent nontumorous tissues.In contrast,P27 level was higher in nontumorous liver tissues than that in HCC.JAB1 overexpression was correlated with histological differentiation,serum alpha-fetoprotein(AFP)level and metastasis(P

Objective To prepare and evaluate the reference materials for plasma von Willebrand Factor antigen testing with fresh frozen plasma.Methods The candidates were prepared by low temperature centrifugation in 5 different concentration levels.The homogeneity and stability of the preparation was evaluated according to the ISO Guide35 and CNAS-GL03.The comparability between STAGO and IL system was evaluated according to the WS/T 356-2011.Then the preparations were characterized by six laboratories with the Secondary Coagulation Standard established by NIBSC(SSCLOT4).Results Homogeneity evaluation of the preparation showed that there was no statistically significant difference between the groups (P >0.05),the F values of factor analysis of variance were 0.317~0.844,the uncertainty range was 1.01% ~2.06%.A linear regression based on stability evaluation indicated that the linear trend (within 24 weeks)was insignificant (P >0.05). The uncertainty range of long-term (within 24 weeks)stability was 0.79% ~ 1.20%.The results of the preparations on STAGO and IL system were comparable.The certificated values of the candidates were range from 12.2% to 138.9% with uncertainties were 0.06%~0.09%,respectively.The range of combined standard uncertainty was 0.03% ~ 0.16% while the expanded uncertainty was 2.2%~6.7%.Conclusion The reference materials for von Willebrand Factor antigen testing were stable and homogenous with comparability between STAGO and IL.The method of characterization was accurate and reliable.

Objective To improve the knowledge,diagnostic level on concealed penis in children,and explore the operative treatment methods of concealed penis.Methods Ten children with concealed penis were reviewed retrospectively in the First Hospital of Jilin University from Jun.2005 to Jul.2007.Patients were 6-12 years old.Penis length was 1.2-2.6 cm.Patients growthing and micturition were normal,the results of androgne and estrogen examination were normal.The etiology was simple obesity in one case,fiber streak of penis sarcolemma in 9 cases.The clinical symptoms and signs,diagnosis and operative method were analyzed.Results The diagnosis of 10 children were correct,and all patients were treated by Devine's operation and 10 cases patients had healed in one stage.There was no vessel,nerve and urethra injury during the operation.The length of penis was 3.0-5.5 cm,average in 3.6 cm after operation.Followed up 3 months to 2 years,10 children's phimosis were removed,the micturition were normal;the appearance of penis was also satisfactory after operation.One patient with under-developed penis had a amelioration after treatment with HCG postoperatively.The penis contour was dissatisfactory in 1 obesity patient,but it was ameliorated gradually while growing up.Conclusions The correct diagnosis and differential diagnosis are very important for operative treatment depend on the different etiology and pathologic changes of concealed penis.Suitable operation can extend the length;moreover,ameliorate the symptom of micturition and the appearance of the penis.
