Objective To analyze the changes of the intima-media thickness(IMT)of carotid and femoral arteries, serum advanced glycosylation end-products(AGEs),and AGEs soluble receptor(sRAGE)after intensively controlling blood glucose, blood pressure, and lipid. Methods One hundred and thirty-two type 2 diabetic patients were divided into 3 groups and followed for 5 years: 20 patients were treated with intensive control of blood glucose and blood pressure, 80 patients with intensive control of blood glucose, blood pressure, and lipid; and 32 patients with conventional therapy. AGEs, sRAGE, and IMT of carotid and femoral arteries were measured and compared among different groups. Results The IMT of carotid and femoral arteries and serum level of AGEs were significantly decreased after intensive treatment. The ratio of sRAGE and HbA1C(sRAGE/HbA1C)were negatively correlated with the mean of HbA1Cin the past five years(r=-0.417, P<0.001)and the fluctuation of HbA1C(r=-0.309,P<0.001). Multinomial regression analysis showed that AGEs were the important risk factors of IMT of femoral artery(β=0.152,P=0.068). Conclusion Intensive treatment is significant in controlling the growing IMT of carotid and femoral arteries, while decreasing serum level of AGEs.

Objective :
To investigate the expression and prognosis of protein regulator of cytokinesis 1 ( PRC1) in pancreatic carcinoma tissues.Moreover,to explore the effects of PRC1 on the biological functions of pancreatic carcinoma cell line SW1990 and its related mechanisms.
Methods:
The GEPIA database was used to analyze the expression difference of PRC1 in pancreatic carcinoma tissues and normal pancreatic tissues.Overexpression and interference of PRC1 were achieved by Lipofectamine 3000 transfection plasmid or shRNA method.Then CCK-8 assay,Transwell assay and flow cytometry were used to detect the proliferation level,invasion ability and apoptosis of the SW1990 cells,respectively.The pancreatic carcinoma data were collected from the Cancer Genome Atlas (TCGA) database.The correlation between expression level of PRC1 and clinicopathological features of pancreatic carcinoma was analyzed.The STRING database was used to analyze the network of proteins interacting with PRC1 . Gene set enrichment analysis ( GSEA) was used to predict the possible signal pathways of PRC1 in pancreatic car- cinoma.
Results:
GEPIA database results showed that PRC1 expression in pancreatic carcinoma tissue was higher than that in normal pancreatic tissue (P<0.05) .The results of CCK-8 assay,Transwell assay and flow cytometry showed that PRC1 overexpression significantly enhanced SW1990 cell proliferation,invasion and inhibited apoptosis (P<0. 01) .Whereas PRC1 interference significantly inhibited SW1990 cell proliferation,invasion and enhanced apoptosis (P<0. 01) .TCGA database data analysis identified PRC1 mRNA expression level and M stage were independent risk factors affecting the prognosis of pancreatic carcinoma (P<0. 05) .STRING database showed that there was an interaction between PRC1 and PLK1 and so on.GSEA research results showed that the PRC1 mRNA high expression samples were enriched into P53 signaling pathway and so on (P<0. 05) .
Conclusion
PRC1 is highly expressed in pancreatic carcinoma,and it is associated with proliferation,invasion,apoptosis and prognosis of pancreatic carcinoma.Moreover,it plays an important role in pancreatic carcinoma by regulating interacting proteins PLK1 and activating P53 signaling pathways.
