Evaluation of color Doppler flow image in malfunction of lower extremity perforator vein / 中国基层医药

Objective To evaluate the diagnostic role of the color Doppler flow image(CDFI) in malfunction of lower extremity perforator vein. Methods Using color Doppler flow image method,60 lower extremities were ex-amined,and compared with the results of the lower extremity vein angiography,then assessed the accuracy of CDFI method. Results 212 lower extremity perforator veins of malfunction were found,and compared with results of the lower extremity vein angiography, the sensitivity of CDFI method is 91.1%, the specificity of CDFI method is 85.8 % ,the accuracy of CDFI method is 91.9 %. Conclusion CDFI is useful for the diagnosis of malfunction of lower extremity perforator vein and can offer reliable bases to clinical operation.

Relationships among Cerebral Vasospasm Following Subarachnoid Hemorrhage and Atrial Natriuretic Peptide and Hyponatremia / 中国康复理论与实践

@#ObjectiveTo explore the relationships among atrial natriuretic peptide (ANP) and cerebral vasospasm (CVS) following subarachnoid hemorrhage (SAH) and hyponatremia.MethodsPlasma ANP levels and serum natrium and blood flow rate of intracal major arterial were assessed at different times (1 to 3 days, 7 days and 14 days after SAH) in 42 patients with SAH. Correlation analysis was carried out among plasma ANP, blood sodium level and blood flow rate of intracal major arterial.Results28 patients had CVS. Plasma ANP levels in CVS patients significantly elevated compared with non-CVS and control subjects (P<0.05). Hyponatremia in CVS patients also significantly elevated compared with non-CVS subjects (P<0.05). Plasma ANP level had significant negative relationship with serum natrium level at the 7th day and 14th day (r2=-0.778,r3=-0.653;P<0.01,P<0.05) in SAH patients. Plasma ANP level had significant positive correlation with middle cerebral artery mean flow velocity on the 7th day (r3=0.702,P<0.05) in SAH patients. Middle cerebral artery mean flow velocity had significant negative relationship with serum natrium level on the 7th day and 14th day (r2=-0.693,r3=-0.653 , both P<0.05) in SAH patients.ConclusionANP might cause hyponatremia following SAH and play an important role in pathogenesis of earlier period CVS.

Analysis of ambulatory EEG in 120 patients with epilepsy or atypical epilepsy / 中国康复理论与实践

@#ObjectiveTo explore the clinical diagnostic value of ambulatory EEG (AEEG) in epilepsy and atypical epilepsy.MethodsThe monitoring of 24-hour AEEG were performed in 67 epileptic and 53 atypical epileptic.Results65.7% of epileptic cases presented abnormality, and 34.0% of atypical epilepsy. The 85.5% of epileptic form discharges were found in the stage of sleep, especially in the Ⅰor Ⅱstage of NREM. The main epileptic form discharges was sharp waves.ConclusionThe monitoring of 24-hour AEEG may play important role in the diagnosis of epilepsy or atypical epilepsy, but can do little in the classification and detecting the focus of epilepsy.

Effects of low frequency electric stimulation at bilateral mastoid processes on motor function and cerebral blood flow of children with cerebral palsy / 中华物理医学与康复杂志

Objective To explore the effects of low frequency electric stimulation at bilateral mastoid processes on motor function and cerebral blood flow of children with cerebral palsy (CP). Methods Ninety children with CP were randomly divided into two groups: an electric stimulation group (group 1) and an conventional rehabilitation control group (group 2), thirty healthy children served as the normal control group. The children of group 1 were treated with FES in addition to the routine rehabilitation treatment. The children of group 2 were given of the routine rehabilitation treatment only. All the patients were treated successively with the above protocol for 3 months. The clinical effect and motor development were evaluated with the gross motor function measure (GMFM), and the blood flow velocities of anterior cerebral artery (ACA), middle cerebral artery (MCA), posterior cerebral artery (PCA) were measured by transcranial doppler (TCD) ultrasound before and after treatment. Results In group 1, significant or some improvement were achieved in 19 and 24 CP children, respectively, with an effective rate of 95.6% . In group 2, significant or some improvement were achieved in 10 and 27 CP children, respectively, with an effective rate of 82.2%. There was significant difference between the two groups with regard to the significant effective rate (P
