Quantitative electroencephalography performance of different brain lobe epilepsy.

OBJECTIVE: To investigate the quantitative electroencephalography features of different brain lobe epilepsy. METHODS: The electroencephalogram data of adult patients diagnosed with epilepsy in the epilepsy clinic of the Second Affiliated Hospital of Shandong First Medical University from January 1, 2012 to December 31, 2016 were collected, 58 cases in total. They included 28 cases of frontal lobe epilepsy,12 cases of temporal lobe epilepsy, 9 cases of occipital lobe epilepsy, and 9 cases of parietal lobe epilepsy. Quantitative electroencephalography analysis technique was used to obtain the δ, θ, α1, α2, ß1 and ß2 power spectrum value in patients with different brain lobe epilepsy. The δ, θ, α, and ß relative power spectrum value are obtained by calculation. By comparing the quantitative electroencephalography indicators of the affected side and the healthy side, the quantitative electroencephalography characteristics of epilepsy in different lobes were obtained. RESULTS: θ power spectrum can be increased in the discharge lead of temporal lobe epilepsy. δ and θ power spectrum, δ relative power spectrum can be increased in the discharge lead of occipital lobe epilepsy. CONCLUSION: The increase in slow wave power spectrum in QEEG can serve as an auxiliary diagnosis for temporal lobe epilepsy and occipital lobe epilepsy.

Viral encephalitis in quantitative EEG.

OBJECTIVE: Our aim was to study the character of quantitative EEG of viral encephalitis. METHOD: Collect the EEG data of hospitalized children with viral encephalitis diagnosed by pediatricians from January 2013 to September 2016, and EEG data of normal cases at the same age were control group. Using quantitative EEG analysis technologies to obtain power spectrum value, power spectrum value, 1 power spectrum value, 12 power spectrum value, 21 power spectrum value, and 12 power spectrum value. Relative power spectrum values of 2 and were obtained by calculation. All the cases were divided into 5 groups according to the EEG character: age 3 group, age 4 group, age 5-6 group, age 7-9-year group, and age 10-14-year group. Viral encephalitis group and normal cases group were statistically compared to obtain characters of quantitative EEG with viral encephalitis. RESULTS: Power spectrum values and power spectrum values of 3-14-year-old cases with encephalitis increased. 1 power spectrum values existed in age 3 group with viral encephalitis and declined at the post-head lead, while 11 and 12 power spectrum values existed in age 4-14 group with viral encephalitis declined at the post-head lead. The value of 2 Power spectrum values of age 3-9 group was limited in diagnosing viral encephalitis. 1 and 12 power spectrum values decrease in age 10-14 group with viral encephalitis. Relative power spectrum values of 2 and increased in age 3-14 group with viral encephalitis; Relative power spectrum values of decreased in age 3-14 group with viral encephalitis, most lead of relative power spectrum decreased in age 3-14 group with viral encephalitis. CONCLUSION: The character of quantitative EEG of cases with viral encephalitis is similar to EEG, but more detailed, more precise, more intuitive and can be used for clinical diagnose of viral encephalitis.

Reappraisal of peripheral NK cells in women with recurrent miscarriage.

The aim of this study was to examine the relationship between peripheral natural killer (NK) cells and recurrent miscarriage by improved methods. Peripheral NK cell measurement was carried out using flow cytometry of morning blood samples obtained in the early follicular phase, analysed within 8 h of collection. Eighty-five Chinese women with recurrent miscarriage who previously tested negative for autoantibodies, and 27 control subjects who were not using any hormonal methods for contraception, were recruited. No significant difference was found in the number of peripheral NK cells and their subsets between women with recurrent miscarriages and control subjects. Only 5% of women with recurrent miscarriage had high peripheral NK cells. The number of previous miscarriages did not appear to have an impact on the number of NK cells. In conclusion, there appears to be limited value in the routine measurement of peripheral NK cells in women with recurrent miscarriage.
