Abstract:
Objective To study the relationship between serum Estradiol(E2 ) andβ-amyloid protein(β-AP) in patients with cer-ebral infarction .Methods A total of 46 female patients with cerebral infarction were selected from 2011 January to 2014 June into observation group ,46 cases were divided as 20 cases in mild group ,16 cases in moderate group ,10 cases in severe group on the basis of neural function defect score standard ,according to the size of infarct volume 46 patients were divided into small infarct volume group with 21 patients ,moderate infarct volume group with 14 cases ,larger infarction volume group with 11 cases .In the same peri-od ,64 healthy women were recruited into control group .Serum E2 ,β-AP levels of serum and cerebrospinal fluid were detected and compared ,and the relationship of serum E2 andβ-AP level in serum ,cerebrospinal fluid were analyzed .Results Theβ-AP levels in serum and cerebrospinal fluid in observation group were higher than those of control group ,the serum E2 level was significant lower than that of the control group ,the differences were significant(P<0 .05) .With more severe cerebral infarction ,β-AP levels in serum cerebrospinal fluid showed an upward trend ,with more severe cerebral infarction ,the serum level of E2 was significantly decreased , andβ-AP ,E2 levels in mild ,moderate ,severe group had significant differences(P<0 .05) .Theβ-AP levels of serum and cerebrospi-nal fluid in higher infarct group were higher than those in small ,moderate infarction group ,but E2 levels were lower than those in small ,moderate infarction group ,the differences had significant(P<0 .05) .There were no significant difference inβ-AP of serum and cerebrospinal fluid ,Serum E2 level between small and moderate infarction group(P>0 .05) .The expression of serum E2 andβ-AP in serum and cerebrospinal fluid were negatively correlated(r= -0 .428 ,P=0 .009;r= -0 .476 ,P=0 .005) .Conclusion β-AP levels in serum and cerebrospinal fluid in patients with cerebral infarction are high ,closely related with the severity of cerebral in-farction .β-AP levels of cerebrospinal fluid ,serum in cerebral infarction patients are negatively related to the level of serum E2 .
