Impact of early dietary gamma-linolenic acid supplementation on atopic eczema in infancy

Polyunsaturated fatty acids (PUFAs) are components of cell membranes and may play an immunomodulating role in the pathogenesis of atopic dermatitis (AD). The goal was to determine the impact of PUFAs on AD by dietary supplementation of infants. Based on the parents' decision on their babies' primary feeding, mothers and newborns were randomized to the supplementation with gamma-linolenic acid (GLA) or placebo for up to 6 months. Breastfed infants received GLA by supplementing their mothers. Formula diet was commercial whey hydrolysate unsupplemented with PUFAs. Of 131 eligible infants, 24 developed AD within the first year of life. Of these, nine belonged to the exclusively breastfed group (n = 58), 14 to the combined-fed group (n = 53), and one to the never breastfed group (n = 20). We could not find an influence of GLA on the development of AD. In subjects with AD, at 1 yr of age the serum-immunoglobulin E (IgE) was the lowest in the GLA-supplemented group A-subjects. In the GLA-supplemented group, GLA-levels in breast milk were similar in atopic and non-atopic infants. In the non-supplemented group the GLA-content of breast milk was 0.07% of total fatty acids in atopic infants vs. 0.17% in non-atopic infants (p < 0.01). Dietary GLA-supplementation could not prevent AD. Interestingly, the number of infants developing AD was the lowest in never breastfed children. In infants suffering from AD, GLA-supplementation seemed to reduce total IgE in the first year of life.     

食管贲门癌术后早期肠内营养支持的应用研究

目的研究食管贵门癌切除术中放置鼻肠营养管进行早期肠内营养，在维持机体营养、促进恢复履在防治术后并发症的作用。方法将90例管责门癌病人随机分为A、B两组，A组术后常规静脉输液，B组术中放置鼻肠营养管，术后第1天给予肠内营养。两组病人监测术前、术后第10天的体重、肠功能恢复排气时间、疲劳评分，吻合口瘘反感染并发症的发生率。结果两组病人在体重、肠功能恢复方面存在明显差异（P〈0．05），在术后并发症方面差异明显（P〈0．01）。结论鼻肠营养管进行早期肠内营养具有易于维持机体营养，促进机体康复，尽快恢复正氮平衡，减少术后并发症的优点。     

Le kiwi, votre partenaire santé

Résumé Le kiwi est par définition une baie : il possède un grand nombre de graines incluses dans une chair comestible. Le kiwi a pour nom latinActinidia et il y a principalement deux espèces d’Actinidia :Actinidia chinensis etActinidia deliciosa. Le kiwi n’est pas seulement un fruit agréable à manger, il est aussi une source exceptionnellement riche en diverses vitamines. Le kiwi est notamment très riche en vitamine C puisqu’il en contient 50 % plus qu’une orange. Le kiwi contient aussi des vitamines K et E. Il est également une source non négligeable de potassium et de folate. Il contient aussi un laxatif, qui plus est, puissant. La qualité nutritionnelle du kiwi ne s’altère pas même pendant une longue durée de stockage pour certains nutriments. Cependant, les risques de réponse allergique ne doivent pas être sous-estimés. The kiwifruit is, by definition, a berry: it has a large number of seeds embedded in fleshy, edible tissue. The Latin name of kiwifruit isActinidia and there are two main species ofActinidia that are commercially important:Actinidia chinensis andActinidia deliciosa. Kiwifruit are not only enjoyable to eat. They are exceptionally good sources of vitamin C and they are also excellent sources of potassium and folate and possibly of vitamin E and vitamin K. They contain a most effective laxative. There is very little, if any, loss of nutritional quality during storage. However, the risks from the allergic response to kiwifruit should not be underestimated.

     

Total and free tissue factor pathway inhibitor in pregnancy hypertension.

OBJECTIVE: To clarify the role played by tissue factor pathway inhibitor (TFPI) in pregnancy hypertension. METHODS: Using enzyme-linked immunosorbent assays, hemostatic measurements were obtained for women with pre-eclampsia (n=51), nonproteinuric hypertension of pregnancy (n=62), postpartum pre-eclampsia 24 h after childbirth (n=31), and no hypertension (healthy pregnant controls, n=100). RESULTS: There was a significant increase in circulating free TFPI levels in women with pre-eclampsia (9.7+/-6.2 ng/mL) or nonproteinuric hypertension of pregnancy (8.3+/-5.3 ng/mL) compared with healthy controls (5.3+/-2.1 ng/mL). In women with pre-eclampsia the levels remained elevated after placental delivery (10.6+/-4.0 ng/mL). Free protein S levels were significantly higher in women with pre-eclampsia (40.0%+/-10.7%), nonproteinuric hypertension of pregnancy (37.1%+/-12.5%), or postpartum pre-eclampsia (39.3%+/-9.1%) than in healthy pregnant controls (32.2%+/-8.5%). CONCLUSION: Increased levels of the physiologically active free forms of TFPI and free protein S, 2 coagulation inhibitors, may protect women with pregnancy-induced hypertension from the risks of hemostatic activation.

哺乳期营养对室间隔心肌细胞发育的影响——游离心肌细胞的形态测量

在心肌细胞分化性生长时期,改变新生鼠的哺乳期营养条件对这些鼠的空间隔心肌细胞将会产生暂时性作用和持久性影响。哺乳期高营养的暂时性作用是增加空间隔心肌细胞的大小和数量;而低营养的暂时性作用则是减慢室间隔心肌细胞的生长。哺乳期高营养的持久性作用是限制室间隔心肌细胞的过度肥大;而低营养则促进成熟鼠的室间隔心肌细胞的过度肥大。
