5.Effect of mycophenolate mofetil on vascular structure and cytokines and receptors of rat with pulmonary arterial hypertension
Chinese Journal of Rheumatology 2011;15(9):625-628
ObjectiveTo observe the effect of mycophenolate mofetil(MMF) on systolic pulmonary arterial pressure (SPAP), right ventricle index (RVI), cytokines, receptors of pulmonary artery hypertension (PAH) rat models. MethodsThe rat models of monocrotaline (MCT)-PAH were developed. Thinty-two Sprague-Dawley male rats were divided randomly into four groups: the control group, the MCT, the MCT +low-dose MMF (20 mg·kg-1·d-1, MMF 20) and the MCT + high-dose MMF(40 mg·kg-1·d-1, MMF 40).There were eight rats in each group. SPAP, RVI, cytokines and receptor in the serum and lung tissue were measured in all rats. Comparisons between multiple groups were performed with q test and rank sum test.Results① Low-dose and high-dose MMF group were compared with the MCT group, SPAP[(40±13),(53±10) vs (68±10) mm Hg]and RVI(0.36±0.06, 0.38±0.03 vs 0.44±0.05) were reduced and showed statistically significant difference respectively(P<0.05). (②) Compared with the MCT group, basic fibroblast growth factor(bFGF) of serum in both low-dose and high-dose MMF group were reduced and showed statistical difference respectively[(2.3±1.9), (2.7:t±1.3) vs (6.9±5.4) pg/ml, P<0.05]. ③ Low-dose and high-dose MMF group were compared with the MCT group and showed that MA was decreased and the musculization of arterial wall was improved. ConclusionMMF can reduce SASP, RVI, number of MA. The inhibitory effect of MMF in PAH is possibly by inhibiting cytokines and receptors.

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.
9.Evaluation of the value of application of continuous glucose monitoring system in a rabbit model of hypoglycemia
Chinese Journal of Comparative Medicine 2017;27(3):68-74
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.
