AIM:To investigate the correlation between matrix metalloproteinase-9(MMP-9),tissue metalloproteinase inhibitor-1(TIMP-1),MMP-9/TIMP-1 and carotid atheromatous plaque stability in cerebral infarction patients.METHODS:80 patients with cerebral infarction were categorized as microemboli-negative group(n=70)and microemboli-positive group(n=10),20 normal human were served as control group.The MMP-9 and TIMP-1 levels in plasma were determined by mean of ELISA in 3 groups.RESULTS:The levels of MMP-9 and TIMP-1 in plasma were significantly higher in cerebral infarction patients than those in control group(P

Objective To study the expression and significance of Ezrin in triple negative breast cancer tissues .Methods We selected 102 cases ,including 24 ones of triple negative breast cancer ,58 ones of non‐triple negative breast cancer ,and 20 of benign breast disease .The expression of Ezrin in all the specimens was detected by SP immunohistochemistry .We observed whether there was any difference between the positive expression rates of Ezrin in the three groups . We also analyzed the correlation between Ezrin expression and clinicopathologic parameters of triple negative breast cancer .Results The positive expression rate of Ezrin in groups of triple negative breast cancer , non‐triple negative breast cancer , and benign breast disease was 15 .00% ,48 .28% and 75 .00% ,respectively . The difference between the three groups differed significantly ( P < 0 .01 ) . The high expression of Ezrin in triple negative breast cancer had relationship with histological grading and clinical TNM staging (P< 0 .05 ) , but not with patients' age , tumor size , or axillary lymph node metastasis ( P > 0 .05 ) . Conclusion Ezrin is highly expressed in triple negative breast cancer tissues ;therefore , it can be used as an important indicator of poor prognosis of triple negative breast cancer .
