Objective To investigate the immune effect and the security after inoculating rabies vaccine in children. Methods To investigate and to detect the antibody level by the way of ELISA among the 337 children wounded by animals and vaccined the rabies vaccine. Results The positive rate of the antibody is 99.7%, the ad-verse effect is moderate. Conclusion Domestic adjuvant-free aqueous rabies vaccine, domestic freeze dried rabies vaccine and peregrinus freeze dried rabies vaccine all have satisfactory immunogenicity and little adverse effect.

Objective To study the role of deleted in liver cancer-1 (DLC-1) gene main domains on the regulation of human colon cancer HT29 cell proliferation.Methods Subcloning recombinant plasmid vectors with Rho GTPase activating protein (RhoGAP),sterile alpha motif (SAM) or steroidogenic acute regulatory-related lipid-transfer (START) domains of DLC-1 gene knockout were constructed and transfected into human colon cancer cell HT29.Wild HT29 cell group (control group),pcDNA3.1-HT29 cell group (vector group) and pcDNA3.1-HT29-DLC-1 cell group (whole DLC-1 gene transfected group) were set as control.The change of cell proliferation was detected by methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay and colony formation test.The cell apoptosis was analyzed by flow cytometry.The activity of RhoA protein was detected by pull-down assay.The differences between the groups were analyzed by the analysis of variance.Results At 48 hours after the successful transfection,compared with control group and vector group,cells proliferation and the activity of RhoA protein were significantly suppressed in whole DLC-1 gene transfected group (F=146.36,698.08,both P＜0.05) and early cell apoptosis increased (F=294.08,P＜0.05).Compared with control group and vector group,there was no significant difference in cell proliferation ability,cell apoptosis and the activity of RhoA protein activity in RhoGAP knockout transfected cells (F=0.99,0.049,5.769,all P＞0.05).Compared with whole DLC-1 gene transfected group,the suppression of cell proliferation was more significant in SAM knockout transfected cells (F=31.00,P＜0.05),the activity of RhoA protein down regulated (F=92.57,P＜0.05) and apoptosis increased (F=130.44,P＜0.05).Compared with whole DLC-1 gene transfected group,the ability of cell proliferation increased (F=15.47,P＜0.05),apoptosis cell decreased (F＝110.23,P＜0.05) and the activity of RhoA protein up regulated (F=199.39,P＜0.05) in START knockout transfected cells.Conclusions The role of DLC-1 gene in the suppression of cell proliferation in HT29 cells was RhoGAP-dependent.SAM domain may be the self suppression domain for endogenous RhoGAP activity.START domain may take effect through enhancing RhoGAP domain.

We reported a rare case with metastatic prostate cancer complicated with hemorrhagic syndrome caused byprimary hyperfibrinolysis.The correct diagnosis of bleeding disorders is a prerequisite for choosing the correct treatment.Tranexamic acid can be used as the preferred treatment for patients with bleeding caused by primary hyperfibrinolysis. In this case, the combination of antifibrinolytics and antiandrogen therapy effectively controlled the severe bleeding symptoms caused by primary hyperfibrinolysis in metastatic prostate cancer. Appropriate treatment after early diagnosis is essential to prevent bleeding and improve prognosis.
