Objective To investigate the protective effects of Radix Paeoniae Rubra(RPR)extracts on reticulum stress and macrophage infiltration on diabetic cardiomyopathy rats and the mechanism. Methods Sprague￣Dawley rats were randomly divided into 5 groups: normol control, model control (induced by streptozotocin),RPR extracts at low dose (i.p.15 g.kg-1 ), middle dose (i.p.30 g.kg-1 ), and high dose (i.p.60 g.kg-1 ).The artery intubation was carried out in all rats for detecting cardiac function 10 weeks later.The myocardial structure was detected by masson staining.The level of myocardial tissue glucose regulatory proteins GRP78,caspase￣12 and caspase￣3 expression were measured by Western blot.The ED￣1 protein was tested by immunohistochemical staining. Results Compared with the normal controls, the model rats presented decreased LVSP, +dp/dtmax ,-dp/ dtmax , LVEF, increased expressions of GRP78, caspase￣12,caspase￣3, ED￣1 and the synthesis of collagen fiber(P<0.05 or P<0.01).RPR extract inhibited the above indexes of model control rats in a concentration￣dependent manner(P<0.05 or P<0.01). Conclusion The RPR obviously ameliorates the cardiac function and myocardial fibrosis of diabetic cardiomyopathy rats,which may be associated with suppressing the expression of GRP78,caspase￣12,caspase￣3 and macrophage infiltration.

AIM: To investigate the effects of globular adiponectin (gAd) on the expression of adiponectin receptor 1 (AdipoR1) in human umbilical vein endothelial cells (HUVECs), and on the apoptosis induced by advanced glycation end products (AGEs). METHODS: HUVECs were treated with the indicated concentrations of AGEs for 24 h or 48 h in vitro. The cells in gAd treatment group were pretreated with gAd for 24 h, and then were treated with AGEs for another 24 h or 48 h. Cell variability was quantified by MTT assay. Apoptotic cells were detected by flow cytometry with Annexin-FITC/PI double staining. AdipoR1 mRNA in the cells was determined by quantitative real time reverse transcriptase-polymerase chain reaction (RT-PCR). RESULTS: The viability of HUVECs treated with AGEs decreased significantly as compared to the cells treated with HSA (control, P<0.05). Under the same condition of AGEs exposure, the viability of the cells treated with gAd was greatly higher than that of the cells without gAd treatment (P<0.01). The apoptotic rate of HUVECs was significantly elevated by AGEs treatment vs HSA treatment observed by Annexin V-FITC/PI double staining analysis with flow cytometry (P<0.05). Under the condition of AGEs stimulation, the apoptosis of HUVECs was decreased by pretreatment with gAd as compared to that of the cells without gAd treatment (P<0.01). Measured by quantitative real time PCR, AGEs decreased the expression level of AdipoR1 mRNA and gAd increased the expression of AdipoR1 mRNA contrarily (P<0.05). CONCLUSION: AGEs increase the apoptotic rate of HUVECs in a concentration dependent manner and gAd promotes the AdipoR1 mRNA expression.
