背景外周动脉波形分析（PWA）是经肺动脉热稀释法校正后的一种测定心排出量（CO）的方法。PWA系统．Flo—Trac／Vigileo（FTV）法，不需要在使用前定标。我们同时比较了用FTV法和经食管超声心动图（TEE）法测定心排出量的结果。方法选择10例ASAⅠ-Ⅱ，择期行腹腔镜结直肠手术的患者做为研究对象。20G套管针桡动脉置管，与血流动力学监测仪及FTV系统连接，进行PWA分析并测定心排出量（COPWA）。据以往方法进行TEE测定心排出量（COTEE）。记录气管插管后、截石位后5分钟、气腹后5分钟、每30分钟或者每次平均动脉压低于基础值20％的测量值。统计分析用Bland-Altman法。结果比较88个测量值，COTEE值为3．23—12Lt／min（平均6．21±1．85），COPWA值为2．9—8．5Lt/min（平均4．84±1．14），偏差1．17，可信区间-2．02～4．37。所有COTEE和COPWA测定值之间的误差百分率平均为40％，范围27％～50％。结论腹腔镜结肠手术中用TEE和FTV法测定心排出量有明显的临床差异。

Identification of essential language areas by combination of fMRI from different tasks using probabilistic independent component analysis

Journal of Biomedical Science and Engineering 2008年第3期1卷 157-162页

Functional magnetic resonance imaging (fMRI) has been used to lateralize and localize lan-guage areas for pre-operative planning pur-poses. To identify the essential language areas from this kind of observation method, we pro-pose an analysis strategy to combine fMRI data from two different tasks using probabilistic in-dependent component analysis (PICA). The assumption is that the independent compo-nents separated by PICA identify the networks activated by both tasks. The results from a study of twelve normal subjects showed that a language-specific component was consistently identified, with the participating networks sepa-rated into different components. Compared with a model-based method, PICA’s ability to capture the neural networks whose temporal activity may deviate from the task timing suggests that PICA may be more appropriate for analyzing language fMRI data with complex event-related paradigms, and may be particularly helpful for patient studies. This proposed strategy has the potential to improve the correlation between fMRI and invasive techniques which can dem-onstrate essential areas and which remain the clinical gold standard.

Neonatal Nutrition and Later Outcomes of Very Low Birth Weight and Preterm Infants <32 Gestational Age at a Tertiary Care Hospital of Portugal

引用

Open Journal of Pediatrics 2015年第3期5卷 190-198页

Premature infants, especially those born with less than 1500 g, often exhibit slow overall growth. Lack of early nutritional support is an important element. The present authors describe parenteral nutritional practices in a tertiary hospital and evaluate postnatal growth of preterm infants under 32 weeks of gestational age or with a birth weight < 1500 g. For population study, we examined 431 newborn files. Their median gestational age was 29.7 weeks. Of them, 25.4% were small for gestational age (SGA). 77.5% received parenteral nutrition (PN), 54.5% of which was provided on the first day. The average time was 14.7 days. The average weight gain by the 30th day was 425 g. At discharge, 37% were rd month 20% had their weight under P3, decreasing to 10% by the 12th month. Children who initiated PN in the first 24 hours of life had significantly better weight on the 30th day of their life (p th month of corrected age (p = 0.038). And they had better Body Mass Index (BMI) in the 3rd (p = 0.012) and 12th (p = 0.023) months. Despite better feeding practices, there is still significant failure in post natal growth. Early introduction of PN was associated with an improved weight gain, which suggests that nutrition that included amino acids may be critical during the first 24 hours of life.
