Chinese Journal of Primary Medicine and Pharmacy 2009;16(12):2171-2172
Objective To explore the relationship between plasm level of vascular endothelial growth factor (VEGF) and children Anaphylactoid purpura(AP).Methods The concentrations of VEGF in serum were detected with enzyme-linked immunosorhent assay in twenty four children with AP,twenty four children with APN in acute phase and twenty four healthy children.Results The concentrations of VEGF in patients with APN in acute phase,AP and normal control was (244.56±51.12)μg/L,(155.71±50.48)μg/L and (54.91±40.07)μg/L,respectively.Plasma levels of VEGF in children with APN and AP were significantly higher than those in normal control,statistically significant difference was observed (F=95.789,P=0.000<0.01).Conclusion The concentrations of VEGF in serum increases markedly in acute phase of AP,those in APN is higher than in AP.It indicated that VEGF involved in the occurrence and development of AP vaseulitis,and may reflect the extent of pathogenetic condition.

Objective To investigate the clinical significance of NKp44+NK cells in the peripheral blood and synovial fluid of rheumatoid arthritis (RA) patients.Methods The proportions of NKp44+NK cells in the PB of 20 active and 15 remission patients with RA and 20 healthy individuals were detected using flow cytometry.The proportions of NKp44+NK cells in the SF of 10 active patients were detected.Multiple nonparametric test was used to compared the difference of NKp44+NK cells proportions.Clinical data including DAS28,anti-CCP antibody and RF were collected.The relationship between NKp44+NK cells and clinical data was analyzed by Spearman correlation analysis.Results The proportions of NKp44+NK cells in PB of active and remission patients and healthy individuals were (1.480±4.750)%,(0.540±0.590)%,(0.000±0.000)%respectively.The proportion of NKp44+NK cells in PB of active patients was significantly higher than that of remission patients and healthy individuals (x2=46.708,P=0.000).The proportion of NKp44+NK cells in the SF of ten active RA patients was significantly higher than matched PB.There was positive correlation between NKp44+NK cells proportion in PB and SF of active patients and DAS 28 and anti-CCP antibody level.There was no correlation between NKp44+NK cells proportion in PB,SF and RF.Conclusion There is a marked increase in the proportion of NKp44+NK cells in PB and SF of RA patients.Moreover,NKp44+NK cells are positively correlated with DAS28 and anti-CCP antibody,suggesting that NKp44+NK cells may be correlated with disease activity and severity.

5.A novel hormone found in circulation--endogenous ouabain.
Acta Academiae Medicinae Sinicae 2005;27(4):534-538
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.

Aim To observe the change of amyloid, acetylcholine transferase and glial fibrillary acidic protein expression in Macaca Rhesus hippocampal after infused the Aβ_(1-42) and thiorphan and explore the possibility of the establishment of Macaca Rhsus AD model in brain.Method The Rhesus monkeys were anesthetized (im), the skull was exposed by a midline scalp incision, and oriented craniotomy was performed on left side by dental drill.First, neprilysin in cerebral cortex and basal nucleus was consumed by infusion thiorphan. Then cerebral cortex and basal nucleus were slowly infused with fibrilla Aβ_(1-42). Finally, the cannula for thiorphan infusion was implanted into the basal nucleus.Miniosmotic pump (Alzet MODEL 2ML4,) was subcutaneously fixed by bio gel 454 on the calvaria (Loctite Co. Ltd,USA) according to the manufacturer's instructions.After 50 days' survival, animals were deep anesthetized with ketamine and sacrificed. The pathological changes were observed by HE staining and immunostaining in monkey brains.Result Neuronal loss and a proliferation of microglia were detected in hippocampal formation by HE staining.Immuno-staining showed Aβ_(1-42),ChAT and GFAP positive cells density were 0.59±0.05,0.21±0.04 and 0.19±0.04 separately.Compared with control group, the density in experimental groups showed distinct difference in statistic analysis (P<0.01).Conclusion The same pathological change was detected in the thioaphan and Aβ_(1-42) infusion in Macaca Rhesus hippocampal formation as what was found in AD patients.

Corneal opacity is one of the most commonly used parameters for estimating postmortem interval (PMI). This paper proposes a new method to study the relationship between changes of corneal opacity and PMI by processing and analyzing cornea images. Corneal regions were extracted from images of rabbits' eyes and described by color-based and texture-based features, which could represent the changes of cornea at different PMI. A KNN classifier was used to reveal the association of image features and PMI. The result of the classification showed that the new method was reliable and effective.

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 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.
