Objective To explore the relationship between EEG feature and TCD with secondary epileply in cerebrul infarction.Methods EEG and TCD were done and analyzed in 40 patients with secondary epileply in cerebrul infarction.Results The EEG abnormality rate was 95%,TCD abnormaity rate was 87.5%,abnormal EEG mainly showed increase of slow waves with low to middle amplitude,with diffuse or local distribution,epileptiform discharges were foumd only in 9 of the 38 ones,cerebral blood flow(CBF) was increased,decreased or bilateral dissymmetry,abnormal spectral frequency(higher force).Conclusion The abnormality rate of EEG is higher,but the detection rate of epileptiform discharges is lower;Unilateral increased of CBF might predict the side of epileptogenic focus.

Objective:To construct a comprehensive nutritional index after treatment of nasopharyngeal carcinoma patients with intensity-modulated radiation therapy (IMRT), and to analyze its relationship with quality of life and 3-year survival period, and aimed to provide some reference for the management of nasopharyngeal carcinoma patients.Methods:This was a prospective cohort study. The clinical data of 431 nasopharyngeal carcinoma patients who admitted to Beijing Tongren Hospital Affiliated to Capital Medical University from January 2017 to December 2021 were collected using convenience sampling method. To evaluate the nutritional status of the patients, the BMI, change in body weight, hemoglobin, lymphocyte count, and albumin level and other clinical data of the patients were collected before and after intensity-modulated radiation therapy. The comprehensive nutrition index after IMRT was constructed by principal component analysis. The Chinese version of European Organization for Reasearch and Treatment of Cancer quality of life questionnare-Core 30 (EORTC QLQ-C30) and Quality of life questionnaire head and neck cancer module(QLQ-H&N35) were used to evaluate the patients′ quality of life. The best diagnostic cutoff point for predicting patient death within 3 years using ROC, and based on the determined optimal diagnostic cutoff point, all patients were divided into a low comprehensive nutritional index group and a high comprehensive nutritional index group. And analyzed the Pearson correlation between comprehensive nutritional index and quality of life.Differences in 3-year survival between the two groups were compared using the Kaplan-Meier method and Log-rank test.Results:Using the diagnostic threshold of receiver operating characteristic, all patients were divided into low comprehensive nutrition index group ( n=280) and high comprehensive nutrition index group ( n=151).The BMI, percentage of weight change, albumin, hemoglobin, and lymphocyte count of nasopharyngeal carcinoma patients before intensity-modulated radiation therapy were (23.14 ± 2.87) kg/m 2, (1.08 ± 0.14)%, (44.02 ± 4.52) g/L, (147.28 ± 15.57)g/L, (1.76 ± 0.56)×10 9/L, and higher than after intensity-modulated radiation therapy (21.14 ± 4.07) kg/m 2, (0.97 ± 0.16)%, ( 38.99 ± 5.12) g/L, (113.87 ± 18.24)g/L, (0.50 ± 0.18)×10 9/L, respectively, the difference were statistically significant ( t values were 8.34 to 44.47, all P<0.05).The comprehensive nutritional index constructed using principal component analysis was correlated with multiple dimensions of EORTC QLQ-C30) and QLQ-H&N35, with statistically significant differences ( r values were -0.169 - 0.245, all P<0.05). Kaplan-Meier curves indicated that the 3-year survival rate of the high comprehensive nutritional index group was higher than that of the low comprehensive nutritional index group, with 87.42% and 79.29% respectively, and the difference was statistically significant ( χ2=4.53, P<0.05). Conclusions:The constructed comprehensive nutritional index could reflect the comprehensive nutritional status of nasopharyngeal carcinoma patients. Nasopharyngeal carcinoma patients with a low comprehensive nutritional index score had a worse quality of life and shorter 3-year survival. Active intervention and improvement of malnutrition in nasopharyngeal carcinoma patients should be undertaken to improve patient quality of life and improve survival.
