Objective To identity the characteristic metabolites of platelets activation by Plasma metabolic Profiling in acute myocardium infarction ( AMI ) patients.Methods From August 2012 to February 2013, samples in three groups were collected at Tianjin Third Central hospital, including AMI group (25 clinically diagnosis myocardial infarction, 14 male, 11 female, average age 67 ±13 ) , control group(A) and simulation platelet activation group(B) (A and B group composed of 29 health volunteers, 11 male 18 female, average age 65 ±12 ) .After collagen platelet activation on B group, HPLC-LTQ Orbitrap XL MS platform was used to analyze the serum metabolic profiling in three groups respectively.Principal component analysis ( PCA) model and partial least squares-discriiminate analysis ( OPLS-DA) model were established to select characteristic metabolites in A and B group, and then tested in X group to find common ions.Results 20 characteristic metabolites were selected in A and B group.3 different lysophosphatidyl choline, sphingosine 1-phosphate, ethanol amine amides, sphingosine choline phosphate, thromboxane, 14-methyl hexadecanoic acid showed the same changing trend and were significant different between B group and AMI group.Conclusions Characteristic ions selected by metabolic profiling technology had significant distinguishing ability for AMI patients and health control.They may provide early diagnosis for AMI.

The authors report a case of left parietal glioblastoma developed five years after surgical removal of the frontal cavernous malformation. A 36-year-old woman presented with history of seizure for 13 years and left frontal parasagittal mass on MRI. The mass was removed uneventfully, and the histopathologic examination revealed a cavernous malformation. Her seizure disappeared after the surgery. Five years later, the patient developed new symptoms of right leg weakness and paresthesia. Imaging studies followed by pathological study revealed left parietal, parasagittal glioblastoma, which was located posterior to the previous surgical field. Following surgery, she is now on regular follow up with radiation therapy and chemotherapy. The authors report this rare occurence of the glioblastoma following surgical removal of cavernous malformation with review of pertinent literatures.
