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 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 To establish a rabbit model of hypoglycemia and evaluate the accuracy and timeliness of hypoglycemia monitoring by continuous glucose monitoring system (CGMS).Methods Sixteen female New Zealand white rabbits were randomly divided into 4 groups, with 4 rabbits in each group.The rabbits in the control group were given intravenous infusion of saline.The animals in the experimental group were infused with insulin continuously, which were divided into 0.1 U/kg/h insulin group (RI=0.1 U group), 0.2 U/kg/h insulin (RI=0.2 U group) group and 0.4 U/kg/h insulin group (RI=0.4 U group) accordingly.During the experiment, CGMS was monitored for 240 min.Blood samples were collected at a 30-minute interval and the blood glucose level was measured by a hand glucose meter.Results A total of 1296 CGMS monitoring data were obtained during the study period, and 136 BG monitoring data matched with CGMS time were obtained.After the insulin administration, BG and CGMS were significantly decreased.The reduction rates of BG and CGMS were 0.016 and 0.017 mmol/L/min in the RI=0.1 U insulin group, 0.04 and 0.027 mmol/L/min in the RI=0.2U insulin group, and 0.049 and 0.032 mmol/L/min in the RI=0.4 U group.According to whether BG monitoring value was lower than 4.4 mmol/L, the BG-CGMS paring data were divided into hypoglycemia and normoglycemia.In hypoglycemia, the average deviation of BG-CGMS was 0.55 mmol/L (the upper and lower limits were-0.98 and 2.08 mmol/L, respectively) and the absolute difference percentage (RAD) was 40.2% ± 45.2%.The mean deviation of BG-CGMS in normal blood glucose was-0.19 mmol/L (upper and lower limits were-1.38 and 1.00 mmol/L, respectively) and 5.8% ± 5.3% in RAD.The error grid analysis (EGA) showed that the proportion of zone A was 93.4%, 0.7% in zone B, and 5.9% in zone D, and the zone D was distributed in area of low BG and high CGMS.Conclusions The results of this study indicate that CGMS has a significant hysteresis phenomenon when blood glucose is reduced rapidly.When the blood glucose levels fall below 4.4 mmol/L, CGMS may have a risk of overestimating blood glucose.Such risk should be fully considered during CGMS clinical application.
