Background: Hypertrophic pyloric stenosis is the most important cause for propulsive non-bilious vomiting in infants of the first trimester. Extramucous splitting of the hypertrophic pyloric muscle is the surgical gold standard for treatment. Serious major complications of pyloromyotomy (PM) are mucosal perforation and incomplete muscle splitting. The aim of the presented study is to find out if intraoperative complications are predisposed by biometric or biochemical factors. Furthermore, we looked for the influence of the board certification of the primary surgeon. Patients and Methods: 162 infants with IHPS were operated during a six-year period (n = 150 laparoscopic operations). We had 8 major complications (4.9%): iatrogenic mucosal perforation occurred in 6 cases, and incomplete PM in 2 infants. Preoperative demographic data and data resulting from the blood acid-base- and ion-analysis were compared with data of a previously published reference group from our institution (Tr?bs RB. Open j Pediatr, 2014;4: 208-215). Results: The duration of vomiting, the grade of dehydration and the severity of blood alkalosis did not differ between both groups. Furthermore, we found no influence of the gestational age and birth weight on the occurrence of intraoperative complications. It seems that early postnatal age (p = 0.07) and low body weight at surgery (p = 0.055) may contribute to surgical problems. Board certification as a paediatric surgeon did not influence the rate of intraoperative complications. Conclusions: Laboratory data did not show any predisposition to intraoperative complications. It is assumed that small infants with early occurring symptoms carry an elevated risk for intraoperative events. Our data support the hypothesis that the rate of intraoperative complications at PM is mainly influenced by skills and experience of the surgeon.

【目的】分析城市滨水公园场所依恋的特殊性,探讨影响城市滨水公园活力的因素,厘清城市滨水空间活力的作用机制。【方法】通过区分游赏者的场所依恋度,建立城市滨水公园社会连接分析框架。以南京滨江4个典型滨水公园为研究对象,通过问卷调查(n=392),采用t检验、方差分析和卡方检验分析变量间的相关性。【结果】(1)游赏者与自然连接的认知结构存在差异,高依恋度游赏者认同与水生态环境相关的自然体验,中、低依恋度游赏者认同休闲活动的环境体验;(2)游赏者的社交联结在认同感高的场所更易建立;(3)游赏者开展日常性/偶然性游憩活动的行为差异取决于是否将河流看成个体/社区的一部分。【结论】社会连接是分析城市滨水活力的具体指征,是城市滨水游赏者使用滨水环境的一种状态。提升城市滨水空间活力,需要充分考虑游赏者对河流景观的环境态度和游憩行为差异。将场所依恋分析方法应用到城市滨水社会连接研究中,可以增加对城市滨水活力机制的解释深度,为城市滨水活力研究带来新路径。

Plants contain various factors that transiently interact with subunits or intermediates of the thylakoid multiprotein complexes, promoting their stable association and integration. Hence, assembly factors are essential for chloroplast development and the transition from heterotrophic to phototrophic growth. Snowy cotyledon 2 （SCO2） is a DNAj-like protein involved in thylakoid membrane biogenesis and interacts with the light-harvesting chlorophyll-binding protein LHCBI. In Arabidopsis thaliana, SCO2 function was previ- ously reported to be restricted to cotyledons. Here we show that disruption of SC02 in Lotus japonicus results not only in paler cotyledons but also in variegated true leaves. Furthermore, smaller and pale- green true leaves can also be observed in A. thaliana sco2 （atsco2） mutants under short-day conditions. In both species, SCO2 is required for proper accumulation of PSlI-LHCll complexes. In contrast to other variegated mutants, inhibition of chloroplastic translation strongly affects L. japonicus sco2 mutant devel- opment and fails to suppress their variegated phenotype. Moreover, inactivation of the suppressor of variegation AtClpR1 in the atsco2 background results in an additive double-mutant phenotype with variegated true leaves. Taken together, our results indicate that SCO2 plays a distinct role in PSll assembly or repair and constitutes a novel factor involved in leaf variegation.
