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.

Objective To observe the effects of nonsteroidal anti-inflammatory drugs (NSAIDs) on the proliferation of chondrocytes and metabolism of human osteoarthritis (OA) in short-term (48 hours). Methods The human knee OA chondrocytes were cultured in the presence or absence of NSAIDs (celecoxib, diclofenac and ibuprofen). BrdU assays were used to evaluate the effects of NSAIDs on the proliferation of OA chondrocytes. ELISA was used to detect the contents of pro-teoglycan and type-Ⅱcollagen in chondrocytes and culture supernatant. The differences of those indexes were compared be-tween groups. Results The positive rate of BrdU labelling index of chondrocytes increased significantly in ibuprofen group than that of other groups (P<0.05). The content of type-Ⅱcollagen in the culture supernatant increased significantly in di-clofenac group than that of other groups (P<0.05 or P<0.01). The content of proteoglycan in the culture supernatant in-creased significantly in ibuprofen group than that of other groups (P<0.05 or P<0.01). There were no significant differences in the content of type-Ⅱcollagen and proteoglycan between chondrocytes of NSAIDs groups (P>0.05). Conclusion Ibu-profen may stimulate the proliferation and the secretion of proteoglycan of human OA chondrocytes. Diclofenac may stimu-late the secretion of type-Ⅱcollagen of human OA chondrocytes. There were no effects of celecoxib on the proliferation and metabolism of human OA chondrocytes.

Objective The objective of this study is to describe the clinical features and outcomes of connective tissue disease (CTD) patients with mycophenolate mofetil (MMF) and with Pneumocystis jirovecii pneumonia (PJP).Methods We retrospectively reviewed the characteristics,clinical features,treatment and outcomes of PJP in patients with CTD.The clinical variables were compared between groups using t-test.Results ① A total of 17 cases were reviewed.② Sixteen patients were treated with glucocorticoids(GCs) plus immunosuppressive drugs.Only one patient had GCs without immunosuppressive drugs.Sixteen patients were with PJP,10 (63％) patients had MMF.③ Ten MMF patients and 7 non-MMF patients had absolute lymphocyte counts with the average being (557±170)/` and (926±162)/μl,respectively (t=-4.481,P＜0.05).④ Six of 17 patients died during the hospitalization.Five patients of 10 patients with MMF died 1 of 7 patients without MMF died.Fifteen of 17 patients were treated by trimethoprim-sulfamethoxazole (TMP-SMX).Conclusion MMF may be risk factors of PJP in CTD.

Objective To investigate the effect of tunor necrosis factor alpha (TNF-α) antagonist treatment and traditional disease-modifying antirheumatic drugs treatment on the quality of life of male patients with ankylosing spondylitis (AS).Methods In 42 patients with AS open-label study,patients were grouped after consent,and divided into the TNF-α antagonist treatment group and the non-TNF-α antagonist treatment group.All patients were treated for 4 months.The clinical and laboratory indexes and quality of life changes were analyzed before and after the treatment.T test,Pearson's correlation analysis were used for statistical analysis with software version 13.0.Results There were no significant differences in age,disease course,disease activity and the quality of life between the two groups before treatment.Disease activity and the quality of life of the two groups after treatment were improved compared with that of before treatment.After treatment,the Bath ankylosing spondylitis disease activity index (BASDAI) score [(1.9±1.6) scores,(3.0±1.3) scores,t=-2.429,P=0.020],erythrocyte sedimentation rate (ESR) [(9±6) mm/1 h,(18±17) mm/1 h,t=-2.286,P=0.031] and C reactive protein(CRP) levels [(18±21) mg/L,(62±85) mg/L,t=-2.258,P=0.035] of the TNF-α antagonists treatment group decreased significantly than those non-TNF-α antagonist treatment group,while the hemoglobin (Hb) levels [(143±15) g/L,(138±18) g/L,t=2.545,P=0.015] were significantly increased in TNF-α antagonist treatment group.The improvement extent of quality of life was more evident in TNF-α antagonists treatment group,such as,the average score [(72± 15) scores,(55±19) scores,t =3.254,P=0.002].The average degree of improvement in quality of life and BASDAI score,Bath ankylosing spondylitis functional index (BASFI) score were negatively related to the improvement in the TNF-α treatment group (r=-0.497,P=0.018; r=-0.558,P=0.007).Conclusion TNF-α antagonist treatment can not only improve the AS disease activity,but can also improve the quality of sexual life of male patients,which may direct affect on male reproductive system.

Objective To investigate the effect of mycophenolic acid (MPA) on the proliferation of rat pulmonary microvascular endothelial cells (PMVECs) and the effects of MPA on the secretion of endothelin-1 (ET-1) and interleukin-6 (IL-6).Methods PMVECs were cultured by tissue-sticking method.Cells were divided into 5 groups,named as the control group,low-dose MPA group,moderate-dose MPA group,highdose MPA group and super high-dose MPA group,according to the final concentration of MPA (0,0.1,1,10 and 100 μmol/L,respectively).The proliferation of rat PMVECs was detected by cell counting kit-8 (CCK-8).The ET-1 and IL-6 secretion were assessed by radio-immunoassay.One-way analysis of variance was used to detect the differences between the group means.Results The cultured PMVECs of rats in vitro showed fusiform or polygonal in shape,and the expressed factor Ⅷ associated antigen stain was positive.At 24 h,the A values of the 5 groups (from control group to super high-dose MPA group) were 1.15±0.20,1.20±0.13,0.88±0.20,0.62±0.05 and 0.56±0.10,respectively,there was no significant difference in the A values on 450 nm between the control group and the low-dose MPA group (P=0.388),as well as the high-dose MPA group and super high-dose MPA group (P=0.292),but there were significant differences between any other two groups (P＜0.01).At 48 h,the A values of the 5 groups (from control group to super high-dose MPA group)were 2.61±0.21,2.52±0.23,1.99±0.17,0.84±0.16 and 0.65±0.12,respectively,there was no significant difference in the A values on 450 nm between the control group and low-dose MPA group (P=0.094),but there were significant differences in the A values between any other two groups (P＜0.01).At 72 h,the A values of the 5 groups (from control group to super high-dose MPA group) were 2.62±0.24,2.62±0.19,2.37± 0.38,0.79±0.17 and 0.61±0.17,respectively,there was no significant difference in the A values on 450 nm between the control group and low-dose MPA group (P=0.931),but there were significant differences in the A values between any other two groups (P＜0.05).There were no significant differences in the ET-1 concentrations between the control group and low-dose MPA group (P=0.156),and high-dose MPA group and super high-dose MPA group (P=0.262),but there were significant differences in the concentrations between any other two groups (P＜0.01).There were no significant differences in the IL-6 concentrations of the five groups between any of the two groups (P＞0.05).Conclusion MPA can inhibit fetal bovine serum induced rat PMVECs proliferation and the secretion of ET-1 in a dose-dependent manner.

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.
