ABSTRACT
Objective By detecting vascular cysteine-rich 61(Cyr61) related factor,connective tissue growth factor (CTGF),vascular endothelial growth factor (VEGF) and CD105 markers of microvascular density (MVD) of muscle tissue in patients with PM/DM,the role and significance of the expression of Cyr61,CTGF,VEGF and CD105 in the process of vascular lesions of dermatomyosits (DM) and polymyosits (PM) were discussed.Methods The expression of Cyr61,CTGF,VEGF and CD105 markers of micro vascular density (MVD) were detected in 10 cases of DM,10 cases of PM and 20 controls by using immunohistochemical Envision two step method.Data were analyzed using Statistical Product and Service Solutions (SPSS) statistical software.Fisher's exact probability analysis and Spearman correlation analysis were conducted.Results Compared with the control group,Cyr61,CTGF,VEGF positive expression rate in muscle tissue of patients with DM and PM group were significantly different (P＜0.01),the positive expression rates of Cyr61,CTGF,VEGF in DM group and PM group were 90％,70％,90％,80％,80％,70％,and the control group (5％,10％,5％) respectively.In the muscle tissue of patients with DM and PM group,CD105 markers of capillaries could be seen,and MVD in DM and PM group were higher than that in the control group,the difference was statistically significant (F=8.103,P=0.001).Cyr61,CTGF and VEGF protein expression levels in muscle tissueof patients with DM and PM were positively correlated with MVD.Conclusion The muscle tissue of PM/DMpatients may have new blood vessels formation.Cyr61,CTGF,VEGF may be involved in the formation of newblood vessels in the PM/DM muscle tissue.The results of this study suggest that microvascular lesion plays animportant role in the immune pathogenesis of inflammatory myopathy such as PM/DM.
ABSTRACT
Objective] To study the effect of kneading pull-turning methods together with the family care and treatment on children congenital muscular torticollis. [Methods] 60 cases of congenital muscular torticollis were randomly divided into kneading pull-turning methods together with the family care group(treatment group) and conventional massage group(control group) with symptoms, signs and evaluation of clinical curative effect between groups of children. [Results] The treatment group cure rate was 76.67%, control group cure rate was 43.33%, the curative effect of treatment group was obviously better than the control group(P<0.05). [Conclusion] Kneading pull-turning methods together with the family care in treatment of children with congenital muscular torticollis has the characteristics of high cure rate which is conducive to recovery of affected children.
