6.MRI Findings of Spinal Epidural Angiolipomas with Literature Review
Chinese Journal of Medical Imaging 2015;(6):432-434
Purpose To investigate the MRI findings and to improve the understanding of spinal epidural angiolipomas. Materials and Methods MRI findings were retrospectively analyzed in two cases of surgery and pathology proven spinal epidural angiolipomas. Relevant literatures were reviewed. Results Two cases of spinal epidural angiolipomas were located in the lumber and lower thoracic spinal canal. The tumors were elongated or spindle in shape within the epidural space, and parallel to the longitudinal axis. In both cases part of the tumors were hyperintense on T1WI and T2WI, attenuated on fat-saturated sequences with mild enhancement. Some areas were hypointenseon T1WI, hyperintenseon T2WI, unattenuated on fat-saturated sequences with apparent enhancement. Angiolipomas were classified according to the MRI features. One was type I and the other was type III. Both cases were non-infiltrative. Conclusion MRI shows the size, shape, MRI signals and the association with the adjacent structure of spinal epidural angiolipomas. The MRI classification is helpful for improving the understanding of the tumor. MRI is the best imaging modality to diagnose spinal epidural angiolipomas.

Objective To observe the effect of different periodontal therapies on serum levels of tumor necrosis factor-alpha (TNF-α),interleukin-6(IL-6)and C-reactive protein (CRP)in elderly patients with coronary.Methods Totally 90 elderly patients with severe periodontitis were divided into three groups,the control group performed the treatment of coronary heart disease;the periodontal treatment group performed the treatment of coronary heart disease and periodontal treatment;the combine group per-formed periodontal therapy and flap surgery on the basis of the treatment of coronary heart disease.The obvervational index were compared among three groups.Results All patients′clinical indexes of periodontitis of combination group and basic group has im-proved after treatment,the levels of PD,SBI,CAL,PLI,the percentage of bleeding on probing and probing depth were significantly decreased (P <0.05),and had significant adhesion(P <0.05);the contrast between combination group and basic group,the levels of PD,SBI,CAL,the percentage of bleeding on probing and probing depth had notable difference(P <0.05).All patients′clinical indexes of periodontitis of combination group and basic group had improved after treatment,serum levels of TNF-α,IL-6 and CRP were significantly decreased (P <0.05);the contrast between combination group and basic group,serum levels of TNF-α,IL-6 and CRP have notable difference (P <0.05).Conclusion The periodontal basic therapy and periodontal flap therapy can reduce the ser-um levels of TNF-α,IL-6 and CRP of elderly coronary heart disease (CHD),but compared to the routine medicine maintenance therapy,the effect of periodontal flap therapy is better.
8.Atorvastatin reduces atherosclerosis in rabbits with hypercholesterolemia by inhibiting inflammatory response
International Journal of Cerebrovascular Diseases 2014;22(5):381-386
Objective To investigate the roles of interleuldn (IL)-17,IL-10,and matrix metalloproteinase12 (MMP-12) in the pathogenesis of atherosclerosis and further to understand the intervention mechanism of atorvastatin for atherosclerosis.Methods Eighteen Japanese white rabbits were randomly divided into 3 groups:control,model and intervention groups (n =6 in each group).The control group,model group and intervention group were fed basic diet,high-fat diet,and high-fat diet plus atorvastatin (5 mg/(kg·d),respectively for 12 weeks.The levels of serum total cholesterol (TC) and triglyceride (TG) were determined by enzymatic colorimetric method; the levels of low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were determined by selective precipitation method; the levels of IL-17,IL-10,and MMP-12 were measured by double antibody sandwich enzyme-linked immunosorbent assay (ELISA); the pathological morphology changes of atherosclerotic plaque was observe by HE staining; and the thickness of the intima,intima/media ratio,plaque area,and plaque proportion were calculated by image analysis software.Results The expression levels of serum TC,TG,LDL-C,and IL-17,as well as those of IL-17 and MMP-12 of the intervention group were significantly lower than those of the model group (all P <0.05),but they were still higher than the control group (all P <0.05),while there was no significant difference in the level of HDL-C.The level of serum IL-10 of the intervention group was higher than that of the model group and the control group (all P<0.05).The thickness of intima,intima/media ratio,plaque area,and plaque proportion of the intervention group were all significantly lower than those of the model group (all P <0.05).Correlation analysis showed that the plaque proportion was significantly positively correlated with IL-17 (r =0.847,P =0.001) and MMP-12 (r =0.839,P =0.001),and was negatively correlated with IL-10 (r =0.794,P =0.002); IL-17 was significantly positively correlated with MMP-12 (r =0.709,P=0.001),and was significantly negatively correlated with IL-10 (r =0.738,P<0.001).MMP-12 was significantly negatively correlated with IL-10 (r =0.563,P =0.015).Conclusion The increased levels of IL-17 and MMP-12,as well as the decreased level of IL-10 illustrate that inflammatory factors play an important pathological role in the pathogenesis of atherosclerosis.In addition to lipid-lowering effect,atorvastatin may decrease the degree of chronic arterial inflammatory response and play a role in anti-atherosclerosis by decreasing the expression of IL-17 and MMP-12,as well as increasing the expression of IL-10.
