Cronobacter spp. (formerly Enterobacter sakazakii) are special foodborne pathogens. Cronobacter infection can cause necrotizing enterocolitis, sepsis and meningitis in all age groups, especially neonates and infants, with a high fatality of up to 80%, although the infection is rare. Outbreaks of Cronobacter infection are epidemiologically proven to be associated with contaminated powdered infant formula (PIF). Cronobacter spp. can resist dry environments and survive for a long period in food with low water activity. Therefore, Cronobacter spp. have become serious pathogens of neonates and infants, as well as in the dairy industry. In this review, we present the taxonomy, pathogenesis, resistance, detection and control of Cronobacter spp.

连轧张力公式是连轧理论和实践的核心问题,该问题国内外都有大量的研究,20世纪60年代笔者推导了连轧张力微分方程、多机架动态张力公式、稳态张力公式,理论上已作过深入、广泛的分析讨论。日本在20世纪70年代对连轧张力公式进行了理论上的推导和实验验证,特别是浅川基男等人的连轧实验结果更为重要。为此引用了浅川基男的实验数据和宝钢2 050 mm热连轧机上的实测数据,验证了连轧张力公式。

土坡的稳定分析一直是沿着条分法的思路发展的。由于对土体应力状态条件的忽视和条分法本身的缺陷,使得条分法得到的安全系数在工程中的应用面临激烈的挑战。土体不同条件下的应力状态表现为K0效应和变化,它对坡体的安全度影响不可忽视。笔者以考虑土体应力状态为条件,应用土的库伦强度定律和摩尔-库伦准则,推导出平面土坡的安全系数计算公式,与条分法的安全系数对比结果说明这种方法具有概念明确、计算简便、定性可靠的重要特点,可以直接提供于工程应用和参考。

Executive function (EF) is increasingly recognized as being responsible for adverse developmental outcomes in preterm-born infants. Several perinatal factors may lead to poor EF development in infancy, and the deficits in EF can be identified in infants as young as eight months. A prospective cohort study was designed to study the EF in Chinese preterm infants and examine the relationship between EF in preterm infants and maternal factors during perinatal period. A total of 88 preterm infants and 88 full-term infants were followed from birth to eight months (corrected age). Cup Task and Planning Test was applied to assess the EF of infants, and the Bayley Scale of Infant Development (BSID-III) was used to evaluate cognitive (MDI) and motor abilities (PDI) of infants. In comparison with full-term infants, the preterm infants performed more poorly on all measures of EF including working memory, inhibition to prepotent responses, inhibition to distraction, and planning, and the differences remained after controlling the MDI and PDI. Anemia and selenium deficiency in mothers during pregnancy contributed to the differences in EF performance. However, maternal depression, hypertension, and diabetes during pregnancy were not related to the EF deficits in preterm infants. Future research should focus on the prevention of anemia and selenium deficiency during pregnancy and whether supplementing selenium in mothers during pregnancy can prevent further deterioration and the development of adverse outcomes of their offspring.

宣肺败毒方(XFBD)是一种临床用于治疗新型冠状病毒肺炎(COVID-19)病患的中药方剂,在临床实践中表现出了显著的疗效,但对其潜在的药理学机制尚不清楚。本研究结合网络药理学、转录组学和多模型系统生物测定等综合研究方法,研究了XFBD生物活性物质及其药理作用机制。通过高分辨质谱与分子网络相结合,对XFBD中的主要活性物质进行了分析,共鉴定或初步鉴定了104种化合物,包括黄酮类、萜类、羧酸类和其他类型的成分。基于所鉴定的XFBD化学组分,开展了网络药理学分析并将炎症相关通路确定为主要靶点。在脂多糖诱导的急性炎症小鼠模型中,XFBD明显减轻了肺部炎症,降低了血清促炎细胞因子水平。转录组学分析表明,经XFBD治疗后,与巨噬细胞功能相关的基因表达水平发生改变。在巨噬细胞细胞系和斑马鱼创伤模型中,XFBD对巨噬细胞的激活和迁移均有很强的抑制作用。最终,通过多模型系统筛选,发现XFBD中虎杖、芦根、化橘红显著下调巨噬细胞活化,虎杖苷、异甘草苷、毛蕊花糖苷为活性化合物;青蒿和麻黄显著抑制内源性巨噬细胞迁移,麻黄碱、白术内酯和山奈酚为活性化合物。综上所述,本研究通过多模态方法研究了XFBD调节炎症的活性成分以及相关药理学机制,从而为XFBD的临床疗效提供了生物学例证。

This study aimed to explore the association of maternal depression with nutrient intake, growth, and development of preterm infants. A cohort study of 201 infants was conducted in Beijing. Based on the gestational age of an infant and status of the mother, the infants were divided into four groups: non-depression-fullterm (64), non-depression-preterm (70), depression-fullterm (36), and depression-preterm (31). Data on sociodemographic characteristics, nutritional intake, growth, and developmental status of children at 8 months (corrected ages) were collected using a quantitative questionnaire, a 24-Hour Dietary Recall, anthropometric measurements, and the Bayley-III scale. A multivariate analysis was used to evaluate the effects of maternal depression and preterm birth on infant growth and development. The energy, protein, and carbohydrate intake in the depression group was lower than the recommended amounts. The depression preterm groups indicated the lowest Z-scores for length and weight and the lowest Bayley-III scores. Preterm infants of depressed mothers are at high risks of poor growth and development delay.
