Abstract:
Objective To evaluate the relationship between 1H-MRS features of brain glioma and its pathological grade and invasiveness, and the correlation between those features and the expression of VEGF, MMP-9 and uPA.Methods The brain gliomas in 55 patients confirmed by pathology were divided into two groups: high grade and low one.An analysis of intragroup and intergroup differences in some metabolite ratios of 1H-MRS in the tumor parenchyma was conducted.The expression of MMP-9,VEGF and uPA in brain glioma was detected,and the correlation between the above three parameters and changes in metabolite ratios of 1H-MRS were explored.Results There was significant difference and correlation in Cho/Cr and Cho/NAA ratio in the tumor parenchyma between high and low grade(P<0.01).The expression of VEGF and MMP-9 in tumor was significantly different(P<0.01) but with significant correlation(P<0.01),and there was no significant difference and correlation in NAA/Cr ratio and uPA expression(P>0.05).Conclusion VEGF and MMP-9 play an important role in the development of brain glioma.Cho/Cr and Cho/NAA ratios provide an important reference for preoperative grading of brain gliomas and indirectly reflect the expression of VEGF and MMP-9.
