Objective : To investigate the dynamic changes of the expression of GLUT1 mRNA and GLUT4 mRNA in rats myocardium with transient ischemia and reperfusion, and the relationship between the dynamic changes and the time during reperfusion. Methods : In rats, the left anterior descending coronary artery was occluded for 20 min followed by reperfusion for 4 hours, 1, 3 or 7 days as ischemia reperfusion model. The relative content of GLUT1 mRNA and GLUT4 mRNA in myocardium was detected by RT-PCR and gel electrophoresis imaging. Results: During myocardial post-ischemia and reperfusion, the levels of GLUT1 mRNA got up to the peak at 4th hour[ (0.666?0. 003 ) vs (0. 509?0.002) controls , P 0.05). Conclusion; Transient ischemia and reperfusion induce the expression of glucose transporters GLUT1 and GLUT4 genes in rat myocardi- um, which contribute to promote glucose utilization during ischemia, protect ischemic myocardium and improve functional recovery on reperfusion.

Objective: To study the effect of GLP-Ⅱ on residual bowel absorption of glucose in a rat model of short bowel syndrome. Methods: Rats undertaken 75% small bowel resection were randomly assigned to SB group and SB/GLP-Ⅱ group. Another group of weight-matched normal rats(Normal) received normal diet ad libitum was used as control group for SB group. All rats were allowed normal chow on the 1st postoperative day(POD). On the POD6,the intestinal glucose absorption data per unit length as well as per unit weight of ileum were measured by in vivo circulatory perfusion experiment. Results: Length of perfused ileum in 3 groups of rats were not significantly different. Wet weight to length ratio of perfused ileum in SB group was significantly higher than that of normal group,but significantly lower than that of SB/GLP-Ⅱ group. 45min glucose absorption of per cm ileum in SB/GLP-Ⅱ group was significantly higher than that of SB group(P0.05). Conclusions: In a rat model of SBS, GLP-Ⅱ can enhance the intestinal glucose absorption measured as per unit length of resudial ileum and GLP-Ⅱ manifests a trend to increase the glucose absorption measured as per unit wet weight of resudial ileum.

Objective To evaluate the treatment methods of endophthalmitis after IOL implantation. Design Retrospective case series. Participants 15 patients with endophthalmitis after IOL implantation treated by Beijing Xuanwu Hospital in 2002-2008. Meth-ods Vancomycin was injected into vitreous cavity in all patients. Vitrectomy was performed on the patient whose infective bacteria could not be controlled by intravitreal injection. Main outcome measures Infective status, visual function, results of microbiological exami-nation. Result Endophthalmitis occured in 13 cases (86.6%) after 72 hours of cartaract surgery. Microbiological examination was per-formed on 15 cases (aqueous or vitreous sample), 6 cases showed positive results, in which 4 cases were staphylococcus epidermidis. The infection of 12 patients (80%) were controlled with intravitreal injection and 10 patients gained final visual acuity better than 0.1. Three patients received vitrectomy because infective bacteria can not be controlled. Conclusion Staphylococcus epi. may be the major cause of subacute endophthalmitis after cartaract surgery. Antibiotics injected immediately into vitreous cavity can control the infections in most cases.(Ophthalmol CHN, 2009, 18: 270-272)

Objective To investigate the role of Wnt/β-catenin pathway in the glucocorticoids (GC)-mediated Alzheimer' s disease-like pathological changes in vitro.Methods Human embryonic kidney 293 (HEK293/wt) cells stably transfected with the longest human tau (tau441,HEK293/tau) and wild-type HEK293 cells were employed to study the role of GC.Cell viabilities of the two cell lines were examined by cell counting kit-8 ( CCK-8 ).Levels of phosphorylated tau ( p-T205 ) and dephosphorylated tau (Tau-1),β-catenin,phosphorylated β-catenin (p-β-catenin),glycogen synthase kinase-3β (GSK-3β),phosphorylated GSK-3β at Ser9 (ps9-GSK-3β) and Bcl-2 were determined by Western blotting.Results Treatment with 1 μmol/L GC for 48 h decreased the viability of HEK293/wt and HEK293/tau cells to 95.5% ±3.2% and 77.8% ± 4.4% (t =6.60,P < 0.05 ).Moreover,GC treatment decreased the levels of ps9-GSK-3β,Tau-1,β-catenin and Bcl-2 to 47.8% ± 10.4%,53.9% ± 11.7%,50.9% ±7.6%,48.4% ±6.5% of control groups ( t =7.01,3.86,7.09,7.30,all P < 0.05 ),and increased the relative levels of pT205,p-β-catenin to 180.5% ± 22.2%,201.3 % ± 27.6% of control groups (t =5.51,5.27,both P <0.05) only in HEK293/tau cells.Finally,LiCI efficiently prevented the above effects of GC in HEK293/tau cells.Conclusion GC may trigger Alzheimer' s disease-like pathological changes by inhibiting the Wnt/β-catenin pathway and these pathological processes seem to specifically depend on the presence of human tau.

Aim To study effects of loganin and morro-niside on aging astrocytes induced by D-galactose. Methods Cortex astrocytes of newly born rats were cultured in vivo and indentified by immunofluorescence method.Firstly,appropriate D-galactose concentration was selected and effects of loganin and morroniside on proliferation activity of aging astrocytes induced by D-galactose were determined by MTT test.Then SOD, MDA were taken as indicators to study the effects of loganin and morroniside on aging astrocytes induced by D-galactose.Thirdly,growth factors like gliar cell line-derived neurotrophic factor (GDNF),basic fibro-blast growth factor (bFGF)tested by ELISA method and expression of Bax,caspase-3,phospho-extracellu-lar signal-regulated kinese (p-ERK1 /2),phospho-mi-togen-actived protein kinase /extracellular signal-regu-lated kinase kinase (p-MEK1 /2)were taken as indi-cators to discuss the potential protection mechanism. Results Loganin and morroniside exerted certain effects on proliferation of aging astrocytes induced by D-galactose,improving SOD,GDNF,bFGF release and lowering MDA release significantly (P <0.05 ). The expressions of Bax and caspase-3 proteins had no difference between model group and loganin group, morroniside group.While the expressions of p-ERK1 /2,p-MEK1 /2 of loganin group,morroniside group were improved significantly compared with model group.Conclusion Loganin and morroniside have protective effects on aging astrocytes induced by D-ga-lactose,and increase the proliferation ability.Protec-ting their antioxidant systems and improving the expres-sion of p-ERK1 /2,p-MEK1 /2 proteins are possible mechanisms.
