Objective To investigate the prognostic factors of life and functional outcome of the first hemiparetic stroke patients. Methods One hundred and eighteen stroke subjects were registered prospectively. The Barthel index (BI) , Rankin scale (RS) , Mortricity index(MI) , Mini-mental state examination (MMSE) , Montgomery-Asberg depression scale (MADRS) and a scale of general state and risk factors were used to evaluate at the 48th hour, the 15th day and the 90th day after stroke. Results The patients' performance, as demonstrated by their scores with all the evaluation instruments, changed significantly at all the time points of evaluation after stroke (P ＜0.05). There was no significant difference between the performance at the 48th hour and the 15th day after stroke ( P ＞ 0.05 ). But at the 90th day after stroke, the activity of daily living performance and the depression status recovered significantly (P ＜ 0.01 ). Logistic regression analysis showed that, such factors as pneumonia, urinary incontinence within 48th hour and deep sensation disturbance might adversely influence patients' activity of daily living performance at the 90th day after stroke; the muscle strength of upper extremities at the 48th hour, and MMSE scores at the 15th day after stroke acted as the protective factors. Conclusions The stroke patients improved significantly with regard to their clinical and functional manifestations when evaluated 90 days after stroke onset. The main factors influencing the activity of daily living performance 90 days after stroke onset included deep sensation disturbance,pneumonia, urinary incontinence and muscles strength of upper extremities at 48th hour, and MMSE scores at the 15th days after onset.

Objective To determine the random spot albuminuria to creatinine ratio (ACR) of normal pregnant women , to track the pregnancy outcome , and to discuss the predictive value of ACR in women with hy-pertensive disorders complicating pregnancy (HDCP). Methods Except for 87 pregnant women suffering from HDCP, 2 038 pregnant women were enrolled in this study. ACR, routine examinations of blood and urine, blood biochemical, 24-hr urinary protein were determined. Results ACR, but not 24-hr urinary protein level,was sig-nificantly higher in women with HDCP. There was positive correlation between the ACR and 24-hr urinary protein quantitation. Age, gestational weeks, ACR, red blood cells, fasting plasma glucose, serum creatinine, total pro-tein were the independent risk factors for HDCP. The sensitivity , specificity and optimal cut off value of ACR for predicting HDCP were 0.78, 0.63, 1.46 mg/mmol. Conclusions There was positive correlation between ACR and 24-hr urinary protein quantitation , and ACR provided a more sensitive pathway for early predictionof HDCP.

OBJECTIVETo explore the feasibility to evaluate objectively auditory temporal resolution using the iso-modulation depth temporal modulation transfer function (TMTF) derived from the amplitude of evoked response to sinusoidally modulated signals.

METHODSChronic electrodes were implanted in inferior colliculus and auditory cortex of guinea pigs. We recorded the evoked response to sinusoidally modulated tones with modulation frequency being varied from 20 to 400 Hz and modulation depth fixed at 100%. The response amplitude in uV was converted into relative amplitude using the fast Fourier transform (FFT) function provided by Biosig software, and then the iso-modulation depth TMTF was plotted with the relative amplitude changed with modulation frequency. Then we recorded the evoked response to the sinusoidally modulated tones with modulation depth being varied from 100% to 10% and derived the iso-amplitude TMTF comparable to conventional modulation depth threshold TMTF. The derived iso-amplitude TMTF was compared to iso-modulation depth TMTF to determine the validity of iso-modulation depth TMTF.

RESULTSThe iso-modulation-depth TMTF and iso-amplitude TMTF in inferior colliculus and auditory cortex of guinea pigs represented respectively bandpass and lowpass characteristic. The cut-off frequency calculated from the two TMTF methods didn't differ significantly and the cut-off frequency derived from auditory cortex iso-modulation depth TMTF was consistent with behavioral results.

CONCLUSIONSThe TMTF plotted with the response amplitude to sinusoidally modulated tones with the modulation depth fixed at 100% and the modulation frequency was a valid method to evaluate objectively auditory temporal resolution.
