目的 探讨高血压基底节区脑出血患者行神经内镜微创手术、显微镜手术治疗的临床效果。方法 选取收治的102例高血压基底节区脑出血患者的临床资料,根据接受手术方法的不同分为对照组和观察组各51例,对照组行显微镜手术治疗,观察组行神经内镜微创手术治疗。观察两组围术期相关指标、手术前后颅内压、神经功能、预后与术后并发症发生率。结果 观察组手术时间、意识恢复时间、住院时间均短于对照组,血肿清除率高于对照组,术中出血量少于对照组(P<0.05)。手术前,两组颅内压无显著差异(P>0.05),手术后3、7 d两组均有下降,且观察组低于对照组(P<0.05)。手术前两组NIHSS评分、GCS评分无显著差异(P>0.05),手术后两组NIHSS评分均降低,GCS评分均提升,且观察组变化幅度大于对照组(P<0.05)。观察组术后并发症发生率为7.84%,低于对照组的23.53%(P<0.05)。结论 神经内镜微创手术治疗高血压基底节区脑出血患者相比显微镜手术具备手术时间短、创伤小且康复速度快等优势,更有助于提升血肿清除率,降低术后颅内压与并发症发生率,促进神经功能及意识状... 相似文献

目的探讨大面积脑梗死后颅内血管血流动力学动态变化特点及其与临床预后的关系。方法 64例大面积脑梗死患者根据影像学供血模型分为完全大脑中动脉(MCA)型和MCA皮质型,急性期大面积脑梗死患者,利用床旁经颅彩色多普勒(TCD)于入院当天和1周内隔日1次及第14天动态检测颅内血流情况,通过测定脑底动脉血流速度、搏动指数及血流速度比值(RVACA和RVPCA),观察颅内血管血流动力学变化。应用美国国立卫生研究院卒中量表(NIHSS)及3个月后存活者日常生活活动能力量表(Barthel指数)评分评价脑血流动力学和神经功能变化与临床预后的关系。选取我院健康体检者64例作为对照组。对照组为同期健康体检人群。性别与年龄选取与病例组具有可比性。结果大面积脑梗死病灶侧MCA平均血流速度(Vm)、颈内动脉(ICA)平均血流速度均明显低于对照组(P<0.05),完全MCA型组较MCA皮质型组MCA血流速度明显减慢(P<0.01);完全MCA型与MCA皮质型梗死后动态观察除部分再通外,MCA血流动态变化不明显(P>0.05),NIHSS评分及脉动指数(PI)在第3,5,7天较第1天明显增高(P<0.05),在第3,5,7天比较差异无统计学意义(P>0.05)。结论大面积脑梗死患者可通过床旁TCD动态检测,可评价大面积脑梗死患者的闭塞血管部位,及时发现侧支循环代偿及血管再通情况,评价颅内压动态变化,观察脱水降颅压治疗效果;在完全MCA型患者中,治疗过程中如果存在RVACA和RVPCA增高,且NIHSS评分稳定,往往对脱水剂治疗敏感,预后较好,可以考虑内科保守治疗。 相似文献

Summary In order to evaluate the diagnostic and prognostic impertance of serum myoglobin (Mb) determination during acute myocardial
infarction (AMI) we determined the time of first rise of both CK and Mb, that is the time in hours between the onset of pain
and the last normal myoglobin and enzyme determination (TFR for Mb=2.2±1.5 h; TFR for CK=4.0±2.5 h). We also attempted to
evaluate infarct size by mathematical analysis of the serum concentrations of Mb. The average percentage difference between
the infarct size calculated from the CK concentrations and Mb concentrations was 35.8±35.2%. The results show that the determination
of serum myoglobin is a useful and sensitive test for the early diagnosis of AMI. On the other hand, the serum myoglobin cannot
be utilized to evaluate infarct size. The main limitation in the determination of infarct size from the serum Mb concentrations
lies in the extreme variability of the disappearance rate (Kd), mainly resulting from the renal elimination of the substance. 相似文献

BackgroundCarbapenem-resistant Enterobacteriaceae (CRE), especially for carbapenemase-producing Enterobacteriaceae (CPE), is an emerging cause that pose a significant threat to public health. However, efficient therapy has not been established. We assessed the antimicrobial efficacy of meropenem (MEPM) and amikacin (AMK) combination therapy.Material and methodsTotal eight isolates of Escherichia coli or Klebsiella pneumoniae, including CRE and/or CPE have carbapenemase genes were used. The relationship between phenotype and in vivo efficacy was assessed in neutropenic murine thigh infection model. Efficacy was determined using the change in bacterial density and survival rate.ResultsThe combination therapy showed enhanced antimicrobial activities against CRE+/CPE+ and CRE+/CPE-K. pneumoniae isolates than MEPM monotherapy (0.63 ± 0.04 vs. 2.56 ± 0.24 ⊿log10 cfu/mL, p < 0.05; −1.05 ± 0.15 vs. −0.48 ± 0.30 ⊿log10 cfu/mL, p < 0.05). Likewise, the combination therapy showed enhanced antimicrobial activities against CRE+/CPE+ and CRE+/CPE-E. coli isolates than MEPM monotherapy (0.90 ± 0.68 vs. 1.86 ± 0.23 ⊿log10 cfu/mL, p < 0.05; −1.81 ± 0.06 vs. −0.88 ± 0.23 ⊿log10 cfu/mL, p < 0.05). Also, combination therapy group showed similar to higher survival rates in CRE + E. coli infection mice, compared to MEPM monotherapy group.ConclusionOur results are the first supportive data to threat CRE infections with combination therapy of MEPM and AMK with in vivo model. The current results verify the promising utility of the combination therapy with MEPM and AMK against CRE isolates with a wide range of MEPM MICs. 相似文献

Gamma Band Activity (GBA) is increasingly studied for its relation with attention, change detection, maintenance of working memory and the processing of sensory stimuli. Activity around the gamma range has also been linked with early visual processing, although the relationship between this activity and the low frequency visual evoked potential (VEP) remains unclear. This study examined the ability of blind and semi-blind source separation techniques to extract sources specifically related to the VEP and GBA in order to shed light on the relationship between them. Blind (Independent Component Analysis-ICA) and semi-Blind (Functional Source Separation-FSS) methods were applied to dense array EEG data recorded during checkerboard stimulation. FSS was performed with both temporal and spectral constraints to identify specifically the generators of the main peak of the VEP (P100) and of the GBA. Source localisation and time-frequency analyses were then used to investigate the properties and co-dependencies between VEP/P100 and GBA. Analysis of the VEP extracted using the different methods demonstrated very similar morphology and localisation of the generators. Single trial time frequency analysis showed higher GBA when a larger amplitude VEP/P100 occurred. Further examination indicated that the evoked (phase-locked) component of the GBA was more related to the P100, whilst the induced component correlated with the VEP as a whole. The results suggest that the VEP and GBA may be generated by the same neuronal populations, and implicate this relationship as a potential mediator of the correlation between the VEP and the Blood Oxygenation Level Dependent (BOLD) effect measured with fMRI. 相似文献

BackgroundThe diagnosis of migraine is mainly clinical and self-reported, which makes additional examinations unnecessary in most cases. Migraine can be subtyped into chronic (CM) and episodic (EM). Despite the very high prevalence of migraine, there are no evidence-based guidelines for differentiating between these subtypes other than the number of days of migraine headache per month. Thus, we consider it timely to perform a systematic review to search for physiological evidence from functional activity (as opposed to anatomical structure) for the differentiation between CM and EM, as well as potential functional biomarkers. For this purpose, Web of Science (WoS), Scopus, and PubMed databases were screened.FindingsAmong the 24 studies included in this review, most of them (22) reported statistically significant differences between the groups of CM and EM. This finding is consistent regardless of brain activity acquisition modality, ictal stage, and recording condition for a wide variety of analyses. That speaks for a supramodal and domain-general differences between CM and EM that goes beyond a differentiation based on the days of migraine per month. Together, the reviewed studies demonstrates that electro- and magneto-physiological brain activity (M/EEG), as well as neurovascular and metabolic recordings from functional magnetic resonance imaging (fMRI) and positron emission tomography (PET), show characteristic patterns that allow to differentiate between CM and EM groups.ConclusionsAlthough a clear brain activity-based biomarker has not yet been identified to distinguish these subtypes of migraine, research is approaching headache specialists to a migraine diagnosis based not only on symptoms and signs reported by patients. Future studies based on M/EEG should pay special attention to the brain activity in medium and fast frequency bands, mainly the beta band. On the other hand, fMRI and PET studies should focus on neural circuits and regions related to pain and emotional processing. 相似文献
