Objective: The functional relationship between calculated alpha band spectral power and inter-/intra-hemispheric coherence during a three-level working memory task of patients with mild cognitive impairment (MCI) was investigated. Methods: Subjects included 35 MCI patients according to the DSM-IV criteria (mean age: 62.3, SD: 6.5) and 34 healthy controls (mean age: 57.4, SD: 4.0) were selected from the community at large. All subjects performed a simple calculation and recall task with three levels of working memory load while electroencephalograph (EEG) signal was recorded. The spectral EEG power was computed over alpha1 (8.0~10.0 Hz) and alpha2 (10.5~13.0 Hz) frequency bands and was compared between rest stage and working memory processing stage by two-way ANOVA. Post hoc testing analyzed the differences between each two levels of working memory load during task processing. The inter-hemisphere EEG coherence of frontal (F3-F4), central (C3-C4), parietal (P3-P4), temporal (T5-T6) as well as occipital (O1-O2) was compared between MCI patients and normal controls. The EEG signals from F3-C3, F4-C4, C3-P3, C4-P4, P3-O1, P4-O2, T5-C3, T6-C4, T5-P3 and T6-P4 electrode pairs resulted from the intra-hemispheric action for alpha1 and alpha2 frequency bands. Result: There was significantly higher EEG power from MCI patients than from normal controls both at rest and during working memory processing. Significant differences existed between rest condition and three-level working memory tasks (P<0.001). The inter-and intra-hemispheric coherence during working memory tasks showed a "drop to rise" tendency compared to that at rest condition. There was significantly higher coherence in MCI patients than in the controls. When task difficulties increased, the cortical connectivity of intra-hemispheric diminished while the inter-hemispheric connectivity dominantly maintained the cognitive processing in MCI patients. Conclusion: The results of the present study indicate that the alpha frequency band may be the characteristic band in distinguishing MCI patients from normal controls during working memory tasks. MCI patients exhibit greater inter-hemispheric connectivity than intra-hemispheric connectivity when memory demands increase. MCI patients mobilize a compensatory mechanism to maintain the processing effectiveness while the processing efficiency is reduced. 相似文献

目的:临床观察中药加味柴芍六君颗粒治疗腹泻型肠易激综合征(irritable bowel syndrome-diarrhea predomina nt,IBS-D)的临床疗效。方法:将80例IBS-D患者随机分为加味柴芍六君颗粒中药组和培菲康西药组,分别给予加味柴芍六君颗粒及口服培菲康治疗。疗程均为4周,疗程结束后随访3个月,观察疗效。结果:(1)治疗2、4周后、治疗结束后第1个月及第3个月随访时,结果两组的证候总积分改善明显优于治疗前,差异有统计学意义(p0.05);(2)治疗4周后,中药组总有效率为81.1%,西药组为70.4%,2组总体疗效差异无统计学意义(p=0.194);在单项症状方面排便次数和大便性状等改善情况中药组要优于西药,差异具有统计学意义(p0.05);(3)在第1、第3个月随访中药组证候积分改善优于西药组,差异具有统计学意义(p0.05)。结论:临床应用加味柴芍六君颗粒治疗IBS-D具有较好的临床疗效。 相似文献

秋季是小儿腹泻病高发季节,多数由轮状病毒感染所致,因多发生在秋季,故通常称为"秋季腹泻"。本病呈散发或小流行,经粪-口传播,也可通过气溶胶形式经呼吸道感染而致病。潜伏期1~3天。发病年龄以6个月~3岁最多见,4岁以上者少见。 相似文献
