The aim of the experiment was to investigate the effect of VC and bacterial enzyme complex combined with glucose on serum biochemical indexes, immune and antioxidant function of cows with antibiotic poisoning. Twenty cows with antibiotic poisoning, weighing about (250.00±10.23) kg were randomly divided into a control group and an experimental group, with five replicates in each group and two cows in each replicate. The cows in the control group received an intravenous injection of glucose and VC, and the cows in the experimental group received an oral administration of glucose and bacterial enzyme complex for seven days. The results showed that compared with the control group, on the 8th day, the leukocytes, neutrophils, erythrocytes and hemoglobin of cows in the experimental group were significantly decreased ( P<0.05), and the platelets were significantly increased ( P<0.05). The activitiy of ALT and CK, and the concentrations of TBIL, Na, P and BUN in serum significantly decreased ( P<0.05), while the concentrations of ALB and Ca significantly increased ( P<0.05). The concentrations of IgM, IgG, IL-6, IFN-γ, SOD activity and T-AOC in the serum of the cows in the experimental group significantly increased ( P<0.05), while the concentrations of MDA significantly decreased ( P<0.05). On the 8th day of the experiment, there were no significant differences in blood routine, serum biochemistry, antioxidant indexes and immune between the experimental group and healthy cows ( P>0.05). The study indicates that glucose and bacteriase complex treatment can effectively improve the blood routine, serum biochemical, immunity and antioxidant function. [ABSTRACT FROM AUTHOR]

Background: Blood anticoagulation after heart valve replacement is a recognized difficulty all over the world. In this study, we identified the effect of amiodarone on the function of warfarin and confirmed the countermeasure by concluding the genotype distribution of vitamin K epoxide reductase complex 1 (VKORC1) and cytochrome P450 2C9 (CYP2C9) of the patient to predict the security dose of warfarin., Methods: Studying on the VKORC1 (-1639G>A) and CYP2C9 genotype of 271 cases on heart valve replacement in the First Affiliated Hospital of Soochow University from Jan. 2012 to Jan. 2014. Warfarin's multivariable regression equation was taken to calculate their warfarin dosage. In the study, 80 of them were selected and divided into 4 groups according to their different warfarin dosage and their usage of amiodaron. The differences of INR values at the 5(th), 8(th), 11(th), 14(th) days of operation were analyzed., Results: Among the 80 cases, VKORC1 (-1639G>A) AA types accounted for 90%, and AG types accounted for another 10%, while GG types were not found. In addition that, all of the patients (100%) had CYP2C9*1/*1 type, and CYP2C9*1/*3 had not appeared. There was significant difference in INR values between the groups who used amiodarone or not. The pharmacogenetic equation was accurate in the predicting of the warfarin dosage, so that satisfied anticoagulation efficacy had been achieved in 2 weeks after surgery., Conclusion: It is necessary for the patients to do the warfarin pharmacogenetic test to get the suitable dose before heart valve replacement. Amiodarone can enhance the anticoagulant efficacy of warfarin, so the dosages of warfarin should be reduced properly because of the medicine combination, and INR values must be monitored more frequently to make the anticoagulant process secure and efficient.

Objective: To search for the bone mesenchymal stem cell (MSC) subgroup which might be more effective on repairing myocardial damage., Methods: In this experiment, four MSC subgroups were defined based on the surface differentiation antigen detection of mouse bone mesenchymal stem cells (mBMSCs): SCA-1(+)/CD45(+)/CD31(+), SCA-1(+)/CD45(+)/CD31(-), SCA-1(+)/CD45(-)/CD31(-) and SCA-1(+)/CD45(-)/CD31(+). These subgroup cells and unselected mBMSCs were injected into infarcted mouse via tail vein. Echocardiographic heart function measurement and in vivo DiR-labeled stem cells imaging were performed at 48 h after injection. In situ C-kit (a flag antigen of cardiac stem cells) and cardiac-specific differentiation antigen immunohistochemistry detection was made in the infarcted myocardium., Results: The capacity of the SCA-1(+)/CD45(+)/CD31(+) cells on improving heart function was significantly higher than other cell groups (all P < 0.05). In vivo imaging showed that the mean fluorescence intensity of the SCA-1(+)/CD45(+)/CD31(+) cells was also higher than other cell groups (all P < 0.05). Number of cardiac stem cells in the infracted myocardium was significantly increased after the injection of all subgroup cells and unsorted mBMSCs cells for 48 h compared untreated infracted myocardium. The capacity of mobilizing cardiac stem cells is as follows: SCA-1(+)/CD45(+)/CD31(+) >SCA-1(+)/CD45(-)/CD31(+) >SCA-1(+)/CD45(-)/CD31(-) >SCA-1(+)/CD45(+)/CD31(-)., Conclusion: The SCA-1(+)/CD45(+)/CD31(+) subgroups of mBMSCs exhibites the highest capacity to improve cardiac function after myocardial infarction and to mobilize autologous cardiac stem cells compared with other mBMSCs subgroups and unsorted mBMSCs cells.
