Outcome Measures

Primary Outcomes (2)

  • inflammatory biomarkers

    The values of neutrophil-lymphocyte ratio, platelet-lymphocyte ratio and monocyte-lymphocyte ratio will be measured.

    Inflammatory biomarkers were collected within 1 day after the onset of symptoms.

  • cranial Imaging

    According to the cranial Imaging, PE or E patients were grouped into PRES group (typical features presence of vasogenic edema in the white matter of the portions of both cerebral hemispheres) and NOT-PRES group (imaging findings were normal).

    Cranial Imaging was examined within 3 days after the onset of symptoms, such as s headaches, visual changes, seizures, consciousness impairment.

Secondary Outcomes (3)

  • other biochemical parameters

    biochemical parameters were collected within 1 week of the hospital stay.

  • Blood Pressure(BP)

    The BP of patients was obtained within 1hour after the onset of symptoms.

  • pregnancy outcomes

    The pregnancy outcomes will record immediately when the patients deliver.

Study Arms (2)

PRES group

patients in PE or E with PRES

Other: Whether the PE or E patient combined with PRES

NON-PRES group

patients in PE or E without PRES

Interventions

According to the Diagnostic criteria of PRES, all the patients grouped into two groups.

PRES group

Eligibility Criteria
