Human papillomavirus(HPV)is one of the common sexually transmitted viruses in the human reproductive tract,which can cause cervical cancer, genital warts and other related diseases. HPV vaccines could not only prevent infection caused by the same HPV types as vaccines effectively, but also provide additional cross-protection against infection or diseases caused by non-vaccine types. This paper reviewed the cross-protection mechanisms of various types of HPV, the cross-protection effects of the commercial HPV vaccines, as well as the new preventive vaccines in progress, in order to provide a reference for the development of new generation of HPV preventive vaccines with broader protection

Objective To investigate the effects of continuous infusion of moderate dose tranexamic acid and ulinastatin on fibrinolysis during orthotopic liver transplantation (OLT).Methods Thirty ASA Ⅲ or Ⅳ patients aged 34-63 yr with a body mass index of 17-37 kg/m2 and end-stage liver disease score 6-34,undergoing OLT,were randomly assigned to one of 3 groups ( n =10 each):group control (group C) ; group tranexamic acid (group T) and group ulinastatin (group U).The patients received continuous infusion of normal saline at 10 ml/h in group C or ulinastatin at 100 000 U/h in group U immediately after tracheal intubation until 120 min after portal vein was declamped,while in group T the patients received a loading dose of tranexamic acid 1 g followed by continuous infusion at 10 mg· kg-1 ·h- 1.Prothrombin time (PT),activated partial thromboplastin time (APTT),international normalized ratio ( INR),fibrinogen (Fg),D-dimers (D-D) and fibrin degradation product (FDP) were measured before induction of anesthesia (baseline),at 120 min after skin incision,30 min after clamping of portal vein (anhepatic phase),30 and 120 min after declamping (neohepatic phase) and at the end of operation.The amount of blood loss and transfusion were recorded.The patients were followed up after operation for hepatic artery and portal vein thrombosis in groups U and T.Results There were no significant differences in PT,APTT,Fg,INR and amount of blood loss and transfusion among the 3 groups.The plasma D-D concentration and percentage of patients with plasma FDP ＞ 20μg/ml were significantly lower in group T than in group C.There were no significant differences in plasma D-D concentration and percentage of patients with plasma FDP ＞ 20 μg/ml between groups U and C.No hepatic artery and portal vein thrombosis was detected after operation in groups T and U.Conclusion Continuous infusion of moderate dose tranexamic acid can inhibit fibrinolysis during OLT,but can not reduce the amount of blood loss.Continuous infusion of ulinastatin ( 100 000 U/h) has no significant effect on fibrinolysis during OLT.

Objective To study whether stem cell antigen-positive(Sca-1 + )cells from fetal liver can differentiate into neural cells. Methods Sca-1+ cells from male fetal liver were isolated with a magnetic cell sorting kit and transplanted into lethally irradiated female mice (2?103 cells/mouse). The donor cells and their characteristics in recipient brains were identified and detected by FISH and immunohistochemistry double-staining analysis at 2, 4, 6 months after transplantation. Results There existed many male cells in brains of female recipients, including white and gray matters, for brain, midbrain, the ependyma of the ventricular system, and the choroid plexus of the lateral ventri cle. Immunochemistry revealed that the Y chromosome-positive cells expressed many neural specific markers, including Neu N, TuJ-1 , NF-M, GFAP and so on. Statistic analysis showed that ratio of Y chromosome positive cells in brain was (4. 5 ? 0. 5) %, ratio of both Y chromosome and NeuN posi live cells (1. 2 ? 0. 3) %. ratio of both Y chromosome and GFAP positive cells (1. 0 ? 0. 2) %. There was no difference between the ratios of Y chromosome-positive cells in brains 2,4, and 6 month after transplantation. Conclusion Sca-1 + cells from fetal liver, the most of which are regarded as hemato-poietic stem cells, can differentiate into neural cells and astrocytes in the brains of adult mice and survive more than 6 months.

Objective To observe the effects of treadmill training on the expression of axonal guidance factor Netrin-4 and its receptor deleted in colorectal cancer (DCC) protein in the brains of rats with cerebral ischemia.Also to explore how training promotes the recovery of neurological function after cerebral ischemia.Methods Sixty-three adult, male Sprague-Dawley rats were randomly divided into a sham group (n =9) , a model group (n =27) and an exercise group (n =27).A modified version of Longa's method was used to establish an animal model of cerebral ischemia by occluding the right middle cerebral artery (MCAO) in the rats of the model and exercise groups while the rats of the sham group were subjected to the same surgical procedure except that no thread was inserted.The rats of the exercise group were given treadmill training beginning 24 h after the modeling, while those of the other two groups were left on the treadmill without training.The rats' neurological functioning was tested by assigning modified neurological severity scores (mNSS) on the 3rd, 7th and 14th day after modeling.Then the ischemic brain tissue was dissected to detect the expression of Netrin-4 and DCC protein using western blotting and immunofluorescent staining and analysis.Results On the 3rd, 7th and 14th day after modeling, the model and exercise groups had significant differences in their average mNSS scores when compared to the sham group.The average mNSS scores of the exercise group on the 7th and the 14th day were significantly lower than those of the model group at the same time point.The average expression level of Netrin-4 and DCC protein in the exercise group was significantly higher in than the model group on the 7th and 14 th days.Immunofluorescent staining showed that Netrin-4 was mainly observed in the blood vessels and astrocytes in the ischemic brain area.DCC protein was found mainly in neural processes and astrocytes in the same area.Conclusions Treadmill training can improve the recovery of neurological function after cerebral ischemia.Its mechanisms may be partly attributed to up-regulating the expression of Netrin-4 and DCC protein in the ischemic brain area, which strengthens the regeneration and reconstruction of nerves and blood vessels.
