Objective To explore the role of high mobility group box protein 1 ( HMGB1 ) and receptor for ad-vanced glycation endproducts( RAGE) in lupus nephritis( LN) . Methods The serum and urine levels of HMGB1 were detected by ELISA in SLE patients and normal controls, and intrarenal expressions of HMGB1 and RAGE were detected by immunohistochemistry in renal tissues of SLE patients and normal-appearing renal tissues. Results
The serum and urine levels of HMGB1 were significantly higher in SLE patients compared to healthy controls( P<0. 01 ) , in patients with active disease compared to those with inactive disease ( P <0. 05 ) , serum levels of HMGB1 were found to be significantly higher in patients with renal involvement compared to those without renal in-volvement(P<0. 05). In addition, the levels of serum HMGB1 showed positive correlation with SLEDAI,urine pro-tein(24 h) and lencocyte count (P <0. 05). The expression of urine HMGB1 showed positive correlation with SLEDAI ( P<0. 05 ) . Intermediate-intensity staining of HMGB1 and RAGE was detected in renal tubules in normal-appearing renal tissues, however, both renal tubules and glomerular cells had the strong expression of HMGB1 and RAGE in SLE patients. The intrarenal production of HMGB1 and RAGE in SLE patients was obviously higher than that in normal-appearing renal tissues(P<0. 05), and the expression levels of HMGB1 in SLE IV and IV+V were higher than those in SLE II ( P<0. 05 ) . The expression levels of RAGE in SLE IV were higher than those in SLE II(P<0. 05). Conclusion HMGB1 and RAGE may play key roles in the pathogenesis of LN and may associate with the pathology category of LN.

Objective To observe the effects of enriched environment on cognitive function in mice with sepsis-associated encephalopathy and to study the neuron PAS domain protein 4 (NPAS4)/brain deprive neurotrophic factor (BDNF)related mechanisms.Methods Sixty adult male mice were divided randomly into three groups:sham operation with standard environment group (group SS,n =12),cecal ligation and puncture with standard environment group (group CS,n =24),cecal ligation and puncture with enriched environment group (group CE,n =24).All mice were reared in standard environment or enriched environment for 28 days.The fear condition test was conducted on day 29 af-ter operation in mice.The change of NPAS4 and BDNF,the density of dendritic spine were detected by western blot or golgi staining.Results Compared with group SS,the context freezing time, NPAS4 and BDNF expression and the density of dendritic spine in hippocampus decreased significantly in group CS (P < 0.05).Compared with group CS,the context freezing time,NPAS4 and BDNF expression and the density of dendritic spine in hippocampus increased significantly in group CE (P <0.05).No significant difference was observed in the conditional freezing time among three groups.Conclusion Enriched environment can obviously improve cognitive function impairment induced by sepsis-associated encephalopathy,which may be related with up-regulated expression of NPAS4/BDNF,and promoted synaptic plasticity.

AIM\ To observe the effect of methionine enkephalin(Met Enk) on proliferation and mechanism involved by opiate receptor of peripheral blood lymphocyte(PBL) from patients with systemic lupus erythematosus(SLE). METHODS\ Lymphocyte proliferation assay. RESULTS\ Naloxone (Nal,1?10 -6 mol?L -1 )could block the increasing effect of Met Enk(1?10 -8 ～1?10 -6 mol?L -1 )on the PBL proliferation of normal humans,but there was no direct effect on that. However,Nal could not only block the promotive action of Met Enk on PBL proliferation of SLE patients,but there was a direct decreasing effect on it. CONCLUSION\ Endogenous Met Enk may participate in the abnormal regulation with SLE PBL via opiate receptor.

Objective To observe changes of hippocampal levels of pro-inflammatory cytokines in rats with neuropathic pain-induced depression, and to explore the relationship between hippocampal levels of pro-inflammatory cytokines and severity of depression.Methods Twenty-eight adult male rats were randomly divided into two groups: group sham (n=14) and spared nerve injury (group SNI) (n=14).Mechanical withdrawal thresholds (MWT) were measured 1 day before and 7, 14 and 21 days after operation.Sucrose preference test and forced swim test were tested 1-3 days before and 21-23 days after operation.After test, hippocampus was collected.The hippocampal levels of interleukin (IL)-1β, IL-6 and tumor necrosis factor-α (TNF-α) were measured by ELISA.Correlational relationships between hippocampal levels of pro-inflammatory cytokines and sucrose preference were evaluated.Results Compared with group sham, MWT was decreased 7, 14, 21 days after operation (P<0.001).Group SNI displayed decreased sucrose preference 21 days after operation (P<0.01) and increased immobility time in FST 23 days after operation (P<0.05).The levels of IL-6 and TNF-α were increased in hippocampus (P<0.05 or P<0.01).No significant difference was observed in IL-1β.The hippocampal levels of IL-1β (r2=0.60,P<0.01), IL-6 (r2=0.55,P<0.01) and TNF-α(r2=0.60,P<0.01) were negatively correlated with sucrose preference.Conclusion The hippocampal levels of pro-inflammatory cytokines IL-6 and TNF-α are increased in rats with depression induced by neuropathic pain, and the levels of hippocampal pro-inflammatory cytokines are negatively correlated with the severity of depression.

A novel Cu-IUDs material, PU/PEG/Cu nanocomposite, was prepared by melt blending method with thermoplastic polyurethane (PU) as the matrix, with polyethylene glycol (PEG) as a hydrophilic modifier, and with nanometer particles of copper as active matter instead of copper wire or copper tube. The structure, morphology, mechanical properties, thermal stability and water absorption were investigated by using FT-IR, XRD, SEM and so on. The results indicated that the nanometer particles of copper were uniformly dispersed in the matrix in PU/PEG/ Cu nanocomposites. It can be seen that the water absorption ability of this nanocomposite was obviously improved while mechanical properties and thermal stability were at high levels. These results provided a good basis for the studies on the cupric ions release of the nanocomposites in future.
