Objective　To study the effect of the combined use of aminoguanidine (AG) and cyclosporine A (CsA) on acute rejection following cardiac allograft. Methods　Except the control group, all other three groups were respectively treated by AG 600mg/kg every day subcutaneously 0 to 7 days after transplantation, low-dose CsA 2mg/kg every day i.m 0 to 7 days after transplantation, and low-dose CsA plus AG. Inducible nitric oxide synthase (iNOS) expression and nitric oxide (NO) production during acute allograft rejection were detected at 4th day after operation, and the graft survival was observed.Results　Compared with the control group, iNOS expression and NO production were significantly inhibited in the AG-treated group (P＜0.05)，the progression of acute rejection was slightly attenuated and allografted heart survival prolonged. The inhibitory effects of iNOS activity and NO production in the recipients receiving the combined treatment of low-dose CsA plus AG were higher than those receiving low-dose CsA alone. Compared with the low-dose CsA group, low-dose CsA plus AG could significantly reduce the histologic grade of acute rejection (P＜0.01) and prolong the graft survival (P＜0.05). Conclusion　The combined use of low-dose CsA and AG could synergistically suppress iNOS activity and NO production, and significantly prolong allografted heart survival.

At present, more and more studies show that epithelial-mesenchymal transition (EMT) is closely associated with cancer stem cell formation and tumor cell invasion, migration and metastasis.EMT not only enhances the capacity of cancer cell invasion and metastasis, but also makes the cell obtain self regeneration and other stem cell characteristics and promotes the production of cancer stem cells.As a result, the investigation of the relationship between EMT and common stem cells can be served as a new approach for searching for effective ways to control tumor invasion and metastasis.It also can provide new targets for the treatment of tumor.

Objective To explore the effect of evidence-based care on the constipation of psychiatric patients.Methods The constipations in 328 psychiatric patients admitted to our department were intervened with evidence-based nursing.Frequency for defecation,incidence of difficult defecation and incidence of dry stool before intervention were compared to those two weeks after intervention.Result Two weeks after intervention,the defecation frequency,incidence of difficult defecation and incidence of dry stool were all significantly lower than those before the intervention(P<0.001).Conclusions The evidence-based nursing used in care to psychiatric patients with constipation can reduce the incidence of constipation,and relieve their physiological and psychological pains.

Forensic medical talents with creative ability should have ability to find.analyze and solve problems from complex cases.According to teaching practice on the basis of PBL this article illustrates application methods of PBL teaching characters in the training of forensic medical talents with creative ability.

ObjectiveTo study the correlation between human erythrocyte membrane phospholipid profile and insulin sensitivity in elderly diabetic patients. MethodsThe levels of phosphatidylcholine (PC), phosphatidylserine(PS),phosphatidtlinostiol(PI),phosphatidylethanolamine(PE),the maximum erythrocyte deformation index(DImax) , the maximum erythrocyte aggregation index(AImax) and glucose disposal contant Ki (KITT) were measured in 32 cases of elderly diabetics and 30 healthy old subjects. ResultsThe KITT was lower in diabetic patients than in normal controls (P

0.05).The iris diaphragm was flat to mild concave which lead the width of anterior chamber angle increased postoperation, no peripheral synechia was found. Conclusion: Phacoemulsification and foldable posterior chamber intraocular lens implantation through clear corneal incision had no significant influence on the long term intraocular pressure in simple senile cataract patients, the width of anterior chamber angle increased postoperation.

Objective To study the relationship between the mRNA degradation in the retinal cells of rat after death and postmortem interval(PMI) in order to provide a new methods of inferring PMI.Methods The level of ?-actin,Pgk1 and Rpl 4 mRNA in the retinal cell of rat were measured at different time(0,2,4,6,8,10, 12,14,16,18,20,22,24,26,28h)after death by compound fluorescence RT-PCR.The rats executed immediately were used as controls.Results Within 28h after death,the absorbance value of total RNA and the level of ?-actin,Pgk1 and Rpl 4 mRNA in the retinal cells decreased along with the prolongation of PMI.The equations of linear regression fitting the relationship between mRNA degradation and PMI were as follows:Y?-actin=-4436.205X?-actin+127581.7(r2=0.976),Ypgk1=-1993.884Xpgk1+57651.54(r2=0.973),YRpl 4=-1189.791XRpl 4+34533.46(r2=0.955).The return model had remarkable statistical significance(P

The changes of retinal nuclear DNA content in rats after death was detected and the relationship between degradation of retinal nuclear DNA and postmortem interval (PMI) was analyzed. Ninety healthy adult SD rats, female, weighing 250+/-10 g, were randomly divided into 15 groups. At 20 degrees C, the retinal cells were withdrawn every 2 h within 0 to 28 h after death and stained with Feulgen-Vans. Index of density (ID), integral absorbance (IA) and average absorbance (AA) in retinal nucleus were analyzed by image analysis system. And the obtained data were subjected to linear regression analysis by using SPSS12.0 software. The results showed that in retinal nucleus, AA and IA were gradually declined with the prolongation of PMI, while ID had an increased tendency. Within 28 h after PMI, the regression equations were as follows: Y(AA )=-0.009X(AA )+0.590 (R(2)=0.949), Y(IA )=-0.097X(IA )+18.903 (R(2)=0.968), Y(ID)=0.122X(ID)+2.246 (R(2)=0.951). It was concluded that retinal nuclear DNA after death in rats was degraded gradually and had a good correlation with PMI.

Objective To explore the effect of myocardial cell Oil high bilirubin blood newborns.Methods Total bilirubin and myocardial ferment value(AST,LDH,CK,CK-MB)in high bilirubin blood group(n=104)and control group(n=60)were examined at the game time.Once again examined total bilirubin and myocardial ferment value after synthetical treat the hish bilirubin blood group.Results The myocardial ferment value diversity significant (P＜0.01) in bilirubin blood group and control group;mild group and severe group myocardial ferment value dlversity notable(P＜0.01),especially CK-MB.Normal value approach of myocardial ferment with bilirubin value after treat the billrubin blood group.Conclusion Myocardial cell damage is temporary and a period of time can bring about of hish bilirubin blood newborns.
