Results Hierarchical management of medical equipment was realized based on the quantitative evaluation of risk grade. The desired target was implemented, and medical equipment risk was controlled properly.Conclusion The introduction of risk management into medical equipment management benefits medical staff, medical service and patient.

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 investigate the distribution of TCM Syndromes of Parkinson's disease(PD).Methods The 125 PD patients were graded according to Hoehn-Yahr(H&Y) criteria for assessment.The assigned TCM physician investigated TCM syndromes of these patients with the structured questionnaire which was based on literature and experience of experts.Results Of 125 cases,96 ones(76.8%) presented a single syndrome,and 29 ones(23.2%) presented complex syndrome.The positive rate of main syndrome was in an order of deficiency of both the Spleen and Kidney(22.4%),yin deficiency of the Liver and Kidney(18.4%),yang deficiency of the Spleen and Kidney(16%),qi deficiency of both qi and yin(15.2%),phlegm-heat stirring up the wind(12.8%),qi deficiency with blood stasis(4.8%),deficiency of both yin and yang(4%),damp abundance due to the Spleen deficiency(3.2%),endoretention of damp heat(1.6%),stagnation of the Liver qi with deficiency of the Spleen and Liver fire flaring(0.8%).There existed a significant difference in the distribution of TCM syndromes in H&Y 1.0~1.5 and H&Y 2.0~3.0(P

Embryonic stem cells (ESC) can develop into neural cells both in vivo and in vitro, this may elucidate the mechanism of nervous system development. ESC-derived uncommitted neural precursors or progenitors may play a role in future transplantation therapies for injury or deregeneration of nervous system. This article reviews embryonic stem cells differentiating into neural cells and characteristics of its gene expression.
