1.Clinical investigation of knee osteoarthritis with metabolic syndrome
Chinese Journal of Rheumatology 2014;18(11):758-761
Objective To explore the morbidity and clinical characteristics of knee osteoarthritis (OA) complicated with metabolic syndrome (MS).Methods Four hundred and ten patients with knee OA were enrolled into this survey.The subjects were divided into two groups:those with knee OA only:those with both OA and MS.Clinical data in the two groups were evaluated.Results The prevalence of MS was 40.2% in all knee OA patients,there was significant difference between the two groups according to the ratio of male to female (x2=5.853,P=0.001),but no difference between the two groups according to age distribution respectively (P>0.05).For metabolic parameters,waist circumference,triglyceride (TG),low density lipoprotein cholesterol (LDL-C),systolic blood pressure and glycosylated hemoglobin (HbA1c) were significantly increased in the group with both of the two diseases (OA and MS),comparing with those with knee OA only (t=3.123,4.679,2.818,3.697,2.632,2.907,P<0.05).However,there was no difference in both group in serum total cholesterol (TC),high density lipoprotein cholesterol (HDL-C) and fasting plasma glucose level (P>0.05).Incidence of coronary heart disease,diabetes mellitus and hypertension was higher in the group with both OA and MS than that in knee OA only group (x2=6.676 and 104.12,P<0.05).The incidence of diabetes mellitus was not different between the two groups (P>0.05).Conclusion The incidence of metabolic syndrome in knee OA patients is relatively high.Effective treatment should be invited to treat knee OA with MS.
2.Relationship between plasma anti-β2-glycoprotein Ⅰ and cardiovascular disease in systemic lupus erythematosus
Chinese Journal of Rheumatology 2012;16(6):414-417
Objective To investigate the relationship between plasma anti-β2-glycoprotein I (anti-β2-GP I )and cardiovascular disease (CVD) in systemic lupus erythematosus (SLE).Methods Eighty-onepatients with SLE [the mean age was (45±18) years old,among whom 73 were female and 8 were male] and20 controls [the mean age was (43±17) years old,among whom 14 were female,and 6 were male] wereenrolled.Plasma anti-β2-GP I was measured by ELLSA.The relationship between plasma anti-β2-GP I level and CVD in SLE patients was investigated with Logistic regression model.T-test,x2 test,Spearman's correlations and Logistic regression analysis were used for statistical analysis.Results Mean plasma anti-β2-GP I increased significantly in SLE group compared to control group [ (29± 19) vs (14±8) U/ml,t=2.035,P<0.05].The plasma levels of anti-β2-GP I were higher in SLE patients with CVD than those without [(41±25)vs (18±12) U/ml,t=2.038,P<0.05].Plasma anti-β2-GP I level was positively correlated with triglyceride (r=0.337,P<0.05) and renal lesions (r=0.489,P<0.01 ).Plasma anti-B2-GP [ level was negatively correlated with high density lipoproteins (r=-0.385,P<0.05 ) and complement (r=-0.497,P<0.05 ) level.Logistic regression analysis showed that plasma anti-β2-GP I (β=0.675,95%CI0.5070.816,P<0.05) was an independent risk factor for CVD in SLE patients.Conclusion The level of plasma anti-β2-GP I in SLE patients with CVD is high,and it may play a role in the pathogenesis and progression of CVD in SLE patients.

Objective To observe the effect of sinomenine on the proliferation of fibroblast-like synoviocytes (FLS) and expression level of MMP-3 secreted by FLS in rheumatoid arthritis in vitro. Methods FLS were obtained by digesting synovial tissues with collagens and were divided into four groups:sinomenine high, middle, low concentration and control group. The proliferation of FLS was assessed by methyl- thiazolyl-tetrazolium (MTT) assay and the mRNA expression of MMP-3 was measured by semi-quantitative RT-PCR respectively after treated by sinomenine. Results The rate of FLS proliferation was significantly reduced in groups treated by sinomenine. Compared with control group, the mRNA expression of MMP-3 markly decreased in sinomenine groups (P

0.05). Conclusions The LTs synthesis is elevated in RSV bronchiolitis and LTs may participate in the pathogenesis of RSV bronchiolitis. Leukotriene receptor antagonist may play an important role in RSV bronchiolitis. However there still needs further research on the relationship between LTs and eosinophils count in the pathogenesis of RSV bronchiolitis.
8.Microglia mediated inflammatory signaling pathways after ischemic stroke
International Journal of Cerebrovascular Diseases 2017;25(2):174-178
Microglia is the most important immune cell in the central nervous system.It plays a key role in mediating the immune response in the central nervous system.Sterile inflammation is the key factor in the pathophysiological process following ischemic stroke.Microglia is activated and induces a series of inflammatory signals through binding of injuring related ligands to their corresponding receptors.This article introduces the activation of microglia and inflammatory response after ischemic stroke from Toll-like receptors,inflammasome,cytokine receptors,Notch signaling and other signaling pathways.
