OBJECTIVE To investigate the time and dose relation of new urine bio markers in rat model of acute kidney injury induced by genta mycin (GM)to search for more sensitive,noninvasive and specific markers than traditional approaches to monitor nephrotoxicity.METHODS SD Rats were im treated with GM5,20,80 mg·kg -1 or saline once daily.Rats were randomly divided into 20 subgroups:treated for 1 ,3,7,14 d and 14 d followed with 28 d recovery period.Ten rats per group (5 rats per sex)were scarified at 24 h after the last dosing or the end of recovery period.Blood sa mples were col-lected for blood urea nitrogen (BUN)and creatinine(CRE)analysis.Urine was collected at each nec-ropsy for urine protein by dry che mistry method,for kidney injury molecule-1 (KIM-1 )analysis by ELISA, and for β2-microglobulin (β2-MG)analysis by ELISA.Kidneys were obtained for histological exa mination after HE stains.RESULTS Positive protein(3 +)was noted for several fe male animals treated for 7 or 14 d at 80 mg·kg -1 and the tendency of recovery were noted at the end of recovery period.Co mpared with those in saline control group treated for 7 d,the seru m BUN and CRE levels for fe males and the CRE level for males were significantly increased at 80 mg·kg -1 (P <0.05),and the BUN level showed the tendency of increase for males at 80 mg·kg -1 (P >0.05).When treated for 14 d,the seru m BUN and CRE levels for fe males and males at 80 mg·kg -1 and the seru m CRE level for fe males at 20 mg·kg -1 were significantly increased when compared with those in saline control group(P <0.05). The seru m BUN and CRE recovered to base line for all animals treated for 14 d followed by a 28 d recov-ery period.Histopathological observation of kidney tissues indicated that focal tubule dilatation was noted for animals treated for 3 d at 20 and 80 mg·kg -1 ,infla mmatory cell infiltration and focal tubule dilatation were noted at 20 mg·kg -1 and focal renal tubular epithelial cell degeneration,infla mmatory cell infiltra-tion,focal casts (lightly)were noted at 80 mg·kg -1 for animals treated for 7 or 14 d.For animals treated for 14 d followed by a 28 d recovery period,only basophilic tubules and renal casts were noted at 80 mg·kg -1 .New urine bio markers determination indicated that KIM-1 level was significantly increased at 20 and 80 mg·kg -1 for animals treated for 3,7 or 14 d when compared with that in saline control group (P<0.05).For animals treated for 14 d followed by a 28 d recovery period,the KIM-1 level was still significantly higher than saline control group for males and fe males at 80 mg·kg -1 and males at 20 mg·kg -1 (P <0.05 ),but there was evidence for reversal.The β2-MG level was significantly increased at 80 mg·kg -1 for animals treated for 3 d(P<0.05),at 20 or 80 mg·kg -1 for animals treated for 7 or 14 d(P<0.05 or P<0.01 ),when compared with that in the saline control group.For animals treated for 14 d followed by a 28 d recovery period,the β2-MG level was still significantly higher than saline control group for males and fe males at 80 mg·kg -1 and fe males at 20 mg·kg -1 (P <0.05),but there was also evidence for reversal.CONCLUSION Urine KIM-1 and β2-GM are more sensitive and specific markers for early diagnosis of kidney injury induced by GM when compared with the traditional approaches to monitor nephrotoxicity.

Background Benign lymphoepithelial lesion of lacrimal gland is not a common orbital disease in clinic,which mainly presented as symmetrical and painless enlargement of bilateral lacrimal glands.However,the etiology and pathogenesis of this disease is still unclear now.Objective This study was to screen the differentially expressed genes between benign lymphoid epithelial lesion of lacrimal gland and orbital cavernous hemangioma and explore the pathogenesis of benign lymphoepithelial lesion of lacrimal gland at the molecular level.Methods Nine patients diagnosed as benign lymphoepithelial lesion of lacrimal gland in Beijing Tongren Hospital,Capital Medical University were enrolled from September 2010 to April 2013,and nine patients with orbital cavernous hemangioma served as control group.The intraorbital tissue was collected during surgery.Whole-genome gene expression microarray was used to detect the expressed genes,and limma algorithm was used to analyze the differentially expressed genes between the benign lymphoepithelial lesion of lacrimal gland and the orbital cavernous hemangioma.Real-time PCR was used to verify differentially expressed genes,Fisher method and gene ontology (GO) functional analysis were performed to realize function and signaling pathways analysis.This study complied with Helsinki Declaration and the protocol was aproved by Institutional Review Board of Beijing Tongren Hospital,and informed consent was obtained.Results Total 5 260 differentially expressed genes were screened between benign lymphoepithelial lesion of lacrimal gland and orbital cavernous hemangioma.The Fisher function and signaling pathways analysis showed that 109 GO terms were significantly upregulated and 101 GO terms were significantly downregulated,and 32 relevant signaling pathways were significantly upregulated and 25 signaling pathways were significantly downregulated in the benign lymphoepithelial lesion of lacrimal gland.GO analysis showed that the expression enrichment of complement receptormediated signaling pathway was high,then following the upregulation of T cell and B cell signaling pathways and downregulation of mitogen-activated protein kinase (MAPK) and transforming growth factor-β (TGF-β) signaling pathways.Real-time PCR results showed that the expressions of TIPRL,TLR7 and TLR10 genes were significantly higher in the benign lymphoepithelial lesion of lacrimal gland than that in the orbital cavernous hemangioma,with significant differences between the two diseases (Z =-2.03,-2.32,-2.32;all at P＜0.05),which was consistent with the microarray data.Conclusions Gene expression profiles are significantly different between benign lymphoepithelial lesion of lacrimal gland and orbital cavernous hemangioma.Those differentially expressed genes play roles in the upregulation of T cell and B cell signaling pathways,downregulation of MAPK and TGF-β signaling pathways and the change of complement system.It is implied that a comprehensive effect of various genes and pathways participates in the pathogenesis of benign lymphoepithelial lesion of lacrimal gland.
