Objective To investigate the relationship of the serum anti-lysosome associated membrane protein 2 (LAMP-2) antibody levels and anti-neutrophil cytoplasmic antibodies (ANCA)-associated glomerulonephritis.Methods Thirty-three patients with new onset ANCA-associated glomerulonephritis and thirty healthy controls were enrolled.ANCA detection was performed using indirect immunofluorescence (IIF).Enzyme-linked immunosorbent assay (ELISA) was used to detect myeloperoxidase (MPO),proteinase-3 (PR3) and other ANCA-associated antibodies including LAMP-2.The cut-off value of the serum anti-LAMP-2 antibody was determined by a receiver operating characteristic (ROC) curve.Results The serum levels of anti-LAMP-2 antibody in new onset ANCA-associated glomerulonephritis patients were significantly higher than remission stage ANCA-associated glomerulonephritis patients and healthy controls (P ＜ 0.05).The serum levels of anti-LAMP-2 antibody showed no visible difference between the remission ANCA-associated glomerulonephritis patients and healthy controls (P ＞ 0.05).The levels of anti-LAMP-2 antibody showed a strong positive correlation with ESR,Scr,BUN,proteinuria,crescent proportion and Birmingham vasculitis activity score (BVAS) and a negative correlation with Ccr,Hb and Alb.Conclusions Anti-LAMP-2 antibody is correlated with the activity of ANCA-associated glomerulonephritis and the severity of renal damage.It may be a useful indicator on the activity of ANCA-associated glomerulonephritis.

BACKGROUND: Resent studies demonstrate that sciatica is caused by inflammatory reaction of nucleus pulposus, and dorsal root ganglion (DRG) is in involved in this process; however, its pathophysiological changes remain poorly understood. OBJECTIVE: To explore pathogenesis of sciatica related to nucleus pulposus protrusion without mechanical compression. METHODS: Totally 24 male SD rats were randomly divided into the experimental group and control group, with 12 rats in each group, The coccygeal intarvartebral discs of rats were opened to obtain 5 coccygeal nucleus pulposus, mixed with 50 μL physiological saline to prepare suspension. Rats in the experimental group were prepared non-compressive models by injecting suspension to the epidural cavum of rats. Meantime, the same volumes of physiological saline were injected into rats in the control group. The rat hind paw mechanical withdrawal thresholds were measured, pain-related behavior and dorsal root ganglion morphology were observed. RESULTS AND CONCLUSION: In the absence of mechanical pressure, disappearance of the nucleolus, degeneration of the nuclear membrane and significant hyperalgesia derived by auto-transplantation of nucleus pulposus to the epidural cavum of rats were observed. Dorsal root ganglion cells often had hyperemia, edema and intracytoplasmic vacuoles, with large and irregular nuclei. Prominent Nissl bodies were not seen. The Inflammatory reaction derived by autograft nucleus pulpcsus is an important factor in DRG injury and sciatica.

~3H-Clonidine, a potent and selective alpha2-adrenergic agonist was used to label alpha2-a-drenoceptors in intact lymphocytes isolated from rat spleen. Binding of ~3H-Clo-nidine was rapid(t1/2: 2min)and readily reversed by 10umol?L~(-1) clonidine(t1/2: 3-4min). ~3H-Clonidine saturationexperiments indicated a single c1ass of site with a K_D of 6.57?1.63nM and Bmax of 72.4?13.4 fmol/10~7 lymphocytes. Adrenergic agonists competed for ~3H-clonidine binding site with anorder of potency:epinephrine)norepinephrine)isoproterenol. These results show the presence ofalpha2-adrenoceptors in splenic lymphocytes. Computer analysis of competition experiments withadrenergic agonists revealed three classes of sites: high affinity site, medium affinity site and lowaffinity site. The affinity of high affinity site is 2-3 orders of magnitude higher than the one ofmedium affinity site, whereas the latter is the same orders higher than low affinity site Using im-proved Mishell-Dutton method, 10umol?L~(-1) clonidine suppressed the Ig M synthesis and thesuppression was blocked by 10 umol?L~(-1) phentolamine. These results indicate the suppression ofIg M antibody response to SRBC in vitro by clonidine is mediated by the alpha-adrenoceptors.
