Endogenous ouabain (EO) is a recently found hormone that may be secreted from adrenal cortex. As an endogenous mammalian analogue of cardiac glycosides and an inhibitor of the sodium pump, it regulates the body fluid balance, urine sodium extraction and vasoconstrictive tone, and thus plays an important role in the pathogenesis of hypertension and some other cardiovascular disorders. This articke reviews its biological features, receptor and antibody, detection, effects on diseases and relationship with endothelial cells.

ObjectiveTo investigate the clinicopathological characteristics of non-diabetic renal diseases (NDRD) in the patients with diabetes mellitus.MethodsClinicopatholigical data of 202 patients with diabetes mellitus and NDRD identified by renal biopsy from January 1st,2003 to December 31st,2010 were analyzed retrospectively.All the patients were divided into three groups:the young (≤35 years old),the middle-aged (36-59 years old) and the elder (≥60 years old).Clinicopathological characteristics were compared among 3 groups.ResultsIn the young group (n=33),42.4％ of patients presented as chronic glomerulonephritic syndrome,while 36.4％ as IgA nephropathy for pathology.In the middle-aged group(n=136),35.3％ of patients presented as chronic glomerulonephritic syndrome,27.2％ as nephritic syndrome,17.6％ as chronic renal failure,14.7％ as latent glomerulonephritis,and 5.1％ as acute renal failure,while42.6％ as IgA nephropathy for pathology.In the elder group(n=33),30.3％ of patients presented as nephritic syndrome,30.3％ as chronic renal failure,while 27.3％ as membranous nephropathy for pathology.ConclusionsIn clinical manifestation,young patients are mainly chronic glomerulonephritic syndrome,middle-aged patients are diversified,and elder patients are mainly nephritic syndrome andchronicrenalfailure. Inpathology, youngandmiddle-agedpatientsaremainlyIgA nephropathy,and elder patients are mainly membranous nephropathy.

Objective To understand the epidemiologic characteristics and pathogenic virus of cases of viral diarrhea in sentinel hospitals in Liaoning Province.Methods From Jan 2009 to Dec 2011,639 stool samples from sentinel hospitals of Liaoning Province were collected.Rotavirus,human calicivirus,astrovirus and adenovirus were detected by polymerase chain reaction and reverse transcriptase-polymerase chain reaction.The data analysis used chi-squanetest and Fisher's exact test.Results Rotavirus,human calicivirus,astrovirus and adenovirus were detected in 15.96 ％,11.25 ％,1.25％ and 0.31％ of the 639 specimens,respectively.G3 was the most prevailing serotype and P[8] was the most common genotype among 101 group A rotavirus isolates.One strain of group C rotavirus was also detected,which was reported for the first time from Liaoning Province.Phylogenetic analysis showed that this group C rotavirus JX407109 in the present study had the closest genetic relationship with the outbreak strain AB648916 from Japan,with nucleotide sequence consistency of 99 ％.Among the 72 samples of human calicivirus,70 samples were norovirus with G Ⅱ/4 being the predominant genotype,and 2 samples were sapovirus.Astrovirus was detected in 8 samples,most of which were genotype 1.Adenovirus was detected in 2 samples,and both were genotype 41.High incidences of viral diarrhea were noted during the months from December to next year February,and children under 5 years of age had high incidence of rotavirus and astrovirus,while the incidence of calicivirus were similar among different age groups.Conclusions The predominant pathogens of viral diarrhea in Liaoning Province are group A rotavirus and calicivirus.Notably,the group C rotavirus in Liaoning Province shares high genetic consistency with the outbreak strain from Japan.

Objective:To explore the expression and location of TLR5 and NLRC4 on different breast cancer cell lines MDA-MB-231,MCF-7 and MDA-MB-435 and TLR5 activation in breast cancer cell line by recombinant flagellin . Methods:The mRNA level of TLR5 and NLRC4 in MDA-MB-231, MCF-7 and MDA-MB-435 cell were detected with quantitative Real-time PCR and TLR5 expression and location in MDA-MB-231 and MCF-7 cell were detected with Flow cytometry. Induction,expression,purification and i-dentification of recombiant flagellin,including FliC (activating both TLR5 and NLRC4),FliC△90-97(unable to activate TLR5),FliC-L3A (unable to activate NLRC4),FliC△90-97:L3A (unable to activate both TLR5 and NLRC4). 1 μg/ml recombinant flagellin were used to stimulate MCF-7 cell lines,12 h later,the supernate were collected,and ELISA was performed to assess the secretion of IL-8. Results:The mRNA level of TLR5 in MCF-7 cell was 1 700 folds higher than that of MDA-MB-435. TLR5 was expressed in MCF-7 cell surface and ctyosol,while expressed only in cytosol in MDA-MB-231 cell. FliC and FliC-L3A,which were able to activate TLR5 pathway,stimualted MCF-7 cell line to secret IL-8,but FliC△90-97 and FliC△90-97:L3A did not. Conclusion:TLR5 and NLRC4 have been expressed in different breast cancer lines,but there exists difference on the expression level and location of TLR5. Expression level of TLR5 and NLRC4 in MCF-7 cell were higher than other breast cancer lines. TLR5 receptor which is expressed on the surface of breast cancer cell can be activated by flagellin,and these work also provide us experimental basis to further understand the impact of TLR5 activation on breast cancer cell proliferation.
