Renal microcirculation changes can not be reflected also. This study amied at evaluate significance of renal perfusion angiography and the indexes of relevant biochemical in early diagnosis of type 2 diabetic nephropathy. Methods: 30 I-III T2DN patients (DN group) and 25 healthy volunteers (control group) were studied, and both of groups were performed renal perfusion CT angiography imaging examination. Biochemical indexes, which are fasting blood glucose (FBG), urinary albumin excretion rate (UAE), 24 h urine protein quantitation (UPQ), blood urea nitrogen (BUN), serum creatinine (Scr), Cystatin C(Cys C), random albumin to creatinine ratio(ACR), were measured in both of groups, then simplified MDRD (Modification of Diet in Renal Disease) and Cys C equation were used to calculate the Estimated Glomerular Filtration Rate(eGFR). double-renal perfusion contrast scanning in both of groups were also conducted to obtain data of double renal blood flow (BF), blood volume (BV), mean transit time (MTT), and permeability surface (PS) for statistical analysis. Results: The indexes of BF, MTT and FBG, UAE, 24 h UPQ, ACR, Cys C, eGFR were found to have relative strong correlation and statistical significance (P<0.05). BF was shown the negative correlation with those indexes, however MTT had positive correlation with them. The area under ROC (receiver operating characteristic curve), were more than 0.9 for UAE, ACR, NF, and MTT, and it indicate that these indexes have relatively positive effect on the early diagnosis of the DN. For 24 h UPQ, cysteine C, eGFR and BV value, the area Under the curve are between 0.7 and 0.9, which indicates that diagnosis using those index for the disease were accuracy. Thus, the above indexes have better diagnostic efficiency compared to Scr, BUN and eGFR. Conclusion: The biochemical indexes such as UAE, ACR and renal perfusion indexes such as BF and MTT can be applied in the early predicative diagnosis and DN screening. Its diagnosis effect is better than other biochemical indexes.","PeriodicalId":88950,"journal":{"name":"Pathology and laboratory medicine international","volume":"82 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74556438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been shown to regulate the expression of a number of genes, acting as either an activator or repressor of gene expression, depending on the context. It is over-expressed in several cancers, but has been shown to be involved in apoptosis and to have a negative influence on cell growth in part by interactions with p53. Previously, ZBP-89 was shown to activate transcription of the matrix metalloproteinase-3 (MMP-3) gene by binding to a polymorphic promoter element in competition with nuclear factor kappaB (NF-kappaB). NF-kappaB is known to be a key regulator of the inflammatory response, but relatively little is known about regulation of ZBP-89. In order to ascertain whether ZBP-89 is regulated during inflammation, we designed experiments to determine whether and to what extent ZBP-89 levels are affected by inflammatory cytokines. Here we show that ZBP-89 mRNA and protein expression are significantly inhibited in human fibroblasts by the inflammatory cytokine interleukin-1beta. Since any change in the levels of ZBP-89 would presumably impact the regulation of MMP-3 and other ZBP-89 target genes, these results provide important insight into mechanisms involved in fine-tuning the immune response.</p>","PeriodicalId":88950,"journal":{"name":"Pathology and laboratory medicine international","volume":"1 ","pages":"7-12"},"PeriodicalIF":0.0,"publicationDate":"2009-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/plmi.s6249","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29171087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
