Objective To study B lymphocyte subsets(na(?)ve B cells,memory B cells and plas- mablasts)of peripheral blood in patients with rheumatoid arthritis(RA)and its relationship with autoantibod- ies and clinical manifestation.Methods Blood samples and clinical data of 60 patients with RA were enrolled into this study.They were divided into three groups:active,inactive and refractory RA based on clinical mani- festations and 24 healthy controls were included.CD19 and CD27 of B cells in peripheral blood of RA patients and healthy controls were detected using flow cytometry at single-cell level.Frequence of na(?)ve B cells (CD19~+CD27~-),memory B cells(CD19~+CD27~(dim)),plasmablasts(CD19~+CD27~(high))and average fluorescence in- tensity of CD19 were analyzed,and their relationship with clinical manifestations and rheumatoid factor(RF), anti-typeⅡcollagen(anti-CⅡ),anti-cyclic citrullianted peptide(CCP)antibodies were investigatied.Results Frequence of na(?)ve B cells and plasmablasts in peripheral blood of patients with RA was increased compared with normal control.In contrast,memory B cells in patients with RA were decreased.The na(?)ve B cells subset in inactive and refractory RA was higher than that of healthy controls(P<0.05),and the memory B cells subset in those groups was lower than that of healthy controls(P<0.05).The plasmablasts in active and refractory groups of RA were higher than those of healthy controls(P<0.05).The average fluorescence intensity of CD19 in peripheral blood in patients with RA was positively correlated with ESR,C-reactive protein(CRP),healthy assessment questionaire(HAQ),and plasmablasts was positively correlated with arthrocele index.Na(?)ve B cells,memory B cells and plasmablasts subsets had no relation with RF,anti-CⅡand anti-CCP antibodies. Conclusion B cell subsets in peripheral blood of patients with RA are significantly abnormal,characterized by expanded naive B cells and plasmablasts but diminished memory B cells.Plasmablasts are increasesd in active and refractory groups of RA,and have positive correlation with swollen joint index.B cells may play an important rote in the pathogenesis of RA.

Objective To explore the influence of homocysteine(Hcy)on liver cystathionine-?-synthase(CBS)and methylenetetrahydrofolate reductase(MTHFR)system in apoE-/- mice,and determine the effects of atorvastatin and/or folate/vitamin B12 on liver CBS and MTHFR system.Methods Eighty male 6-week-old apoE-/- mice were randomly divided into two groups:65 mice were fed with a chow diet containing 2%(wt/vol)L-methionine(homomethionine group)and 15 mice were fed with normal saline(control group).Two months later,the 60 mice survived in homomethionine group were subdivided into four groups:group Ⅰ(untreated),Ⅱ(3 mg/kg atorvastatin),Ⅲ(3 mg/kg atorvastatin+2 mg/kg folate+30 ?g/kg vitamin B12)and Ⅳ(2 mg/kg folate+30 ?g/kg vitamin B12).After one month,Western blotting was performed to detect the liver CBS and MTHFR system protein expression in each group.Results The relative expression of liver CBS and MTHFR was significantly lower in group Ⅰ than in control group(P

OBJECTIVETo compare the effect of reinforcing Shen method (RSM) and activating blood method (ABM) in treating osteoarthritis (OA) at the molecular level.
METHODSThe physical and chemical characteristics of components from respective recipes of RSM and ABM, and network features of component-target interaction network were analyzed by computer simulation methods including chemical space, molecular docking, and biological network, etc.
RESULTSThe chemical components of RSM and ABM were scarcely scattered with larger overlapping. Among established networks, the distribution of network features was partially similar in RSM and ABM. The average target number correlated with each component was 1.86 in RSM and 2.11 in ABM respectively. Each average target number was respectively correlated with 4.46 compounds and 3.93 compounds, reflecting multi-component and multi-target actions.
CONCLUSIONComputer simulation could intuitively trace out similarities and differences of two different methods and their interaction with targets, which revealed that the compatibility of RSM and ABM could have broader protein targets and potential synergism at the molecular level.

Objective To investigate whether homocysteine(Hcy) induces apoptosis of endothelial cells via a pathway involving caspases3 and whether simvastatin antagonizes the proapoptotic effects of Hcy by regulating c-IAP. Methods Human umbilical vein endothelial cells(HUVEC) were treated with Hcy,with or without simvastatin,for 24 h.Cell apoptosis was evaluated by Annexin V staining and flow cytometery,as well as TUNEL.The mRNA and protein levels of caspase3,c-IAP-1 and c-IAP-2 were analyzed by RT-PCR and Western blot,respectively. Results Treatment with both low(0.5 mmol/L) and high(3.0 mmol/L) concentrations of Hcy-induced HUVEC apoptosis was accompanied by an increased level of caspase3 expression and activation,together with decreased c-IAP-1 and c-IAP-2 level.Simvastatin upregulated c-IAP-1 and c-IAP-2 expression while attenuated Hcy-induced apoptosis and caspase3 activation. Conclusion Hcy may induce HUVEC apoptosis via a pathway involving caspase3,which can be partially antagonized by simvastatin,possibly through upregulated c-IAP-1 and c-IAP-2 expression.

·AIM: To improve our understanding of retinoschisis at the macular area.·METHODS: From January 2003 to January 2005, the patients whose macular retinoschisis was confirmed by optical coherence tomography (OCT) were included in the study. Their data and other results were further analyzed.·RESULTS: During that period, macular retinoschisis was found in 116 eyes which fit the including criteria. Among these, 94 eyes were pathological myopia; 17 were X-linked congenital retinoschisis; and 5 had excavation of optic disk.By analyzing the OCT figures, it was found that retinoschisis could happen at many locations within retinal neural epithelium, including inner, middle and outer part. The retinoschisis caused by different reasons differs in OCT results.·CONCLUSION: Retinoschisis at the macular area was not rare at the clinic, and the retinoschisis may be located at different parts of the retina. OCT was useful in the diagnosis and follow-up of macular retinoschisis.
