摘要：
Bowel diseases are common in human and animals and are characterized by intestinal dysfunction and injury. A well-established porcine model of intestinal injury can be induced by lipopolysaccharide (LPS), an endotoxin released from the cell wall of pathogenic bacteria. LPS affects the expression of genes associated with intestinal immune response, mucosal growth, energy metabolism, absorption, mucosal barrier function, and antiviral function. Transcriptional analysis of intestinal genes reveals that the duodenum, jejunum, ileum and colon respond to LPS challenge in a similar pattern. Moreover, the jejunum and ileum exhibit greater responses to LPS challenge than the duodenum and colon with regard to gene expression. Additionally, over 85% of genes are co-expressed along the small and large intestines and there is a clear distinction in gene expression patterns amongst the different intestinal segments in pigs. These findings have important implications for underlying molecular mechanisms responsible for endotoxin-induced intestinal injury and dysfunction.

摘要：
Background: Skeletal muscle undergoes rapid loss in response to inflammation. a-Ketoglutarate (AKG) has been reported to enhance muscle growth in piglets, but the underlying mechanisms are largely unknown. Objectives: This study tested the hypothesis that dietary AKG supplementation activates mechanistic target of rapamycin (mTOR) signaling and improves skeletal muscle energy metabolism in lipopolysaccharide (LPS)-challenged piglets. Methods: Forty-eightmale piglets (Duroc × Landrace × Yorkshire)wereweaned at 21 d of age to a corn- and soybeanmeal- based diet. After a 3-d period of adaptation, piglets with a mean weight of 7.21 kg were randomly assigned to control, LPS (intraperitoneal administration of 80 μg LPS/kg body weight on days 10, 12, 14, and 16), or LPS plus 1% dietary AKG (LPS +AKG) groups. On day 16, blood sampleswere collected from8 piglets/group 3 h after LPS administration.On day 17, piglets were killed to obtain gastrocnemius muscle from 8 piglets/group for biochemical analysis. Results: Compared with the control group, LPS administration increased (P < 0.05) plasma concentrations of globulin (by 14%) and tumor necrosis factor α (by 59%) and the intramuscular ratio of AMP to ATP (by 93%) and abundance of phosphorylated acetyl- coenzyme A carboxylase (ACC) β protein (by 64%). Comparedwith the control group, LPS administration reduced (P < 0.05) weight gain (by 15%); plasma concentrations of glutamine (by 20%), glucose (by 23%), insulin, insulin-like growth factor I, and epidermal growth factor; intramuscular concentrations of glutamine (by 27%), ATP (by 12%), ADP (by 22%), and total adenine nucleotides; and intramuscular ratios of phosphorylated mTOR to total mTOR (by 38%) and of phosphorylated 70-kDa ribosomal protein S6 kinase (p70S6K) to total p70S6K (by 39%). These adverse effects of LPS were ameliorated (P < 0.05) by AKG supplementation. Conclusions: Dietary AKG supplementation activated mTOR signaling, inhibited ACC-β, and improved energy status in skeletal muscle of LPS-challenged piglets. These results provide a biochemical basis for the use of AKG to enhance piglet growth under inflammatory or practical postweaning conditions. © 2016 American Society for Nutrition.

摘要：
This study was carried out to investigate the effects of N-acetylcysteine (NAC) on growth performance and intestinal function of heat-stressed broilers. A total of two hundred 1-d-old Cobb male chicks were allocated to 1 of 4 treatments, with 5 replicated pens per treatment and 10 birds per pen. The experiment consisted of 4 treatments in a 2 × 2 factorial arrangements with two diets (basal diet or 1 g/kg NAC diet) and two temperatures (thermoneutral or heat stress). From day 8–35 of age, broilers were raised at thermoneutral (26 ± 1 °C) or exposed to cyclic heat stress (36 ± 1 °C from 0800 to 1800 and 26 ± 1 °C from 1800 to 0800). The results showed that heat stress reduced ADFI, ADG, plasma concentrations of triiodothyronine (T3) and thyroxine (T4), intestinal villus height (VH), ratio of VH to crypt depth (CD), intestinal mucosal ATP level, adenylate energy charge (AEC), activities of alkaline phosphatase (AKP), antioxidative and digestive enzymes, and mRNA level for Bcl-2, whereas increased the feed/gain, mortality rate, plasma corticosterone level, intestinal CD, intestinal mucosal AMP and malondialdehyde (MDA) levels, and mRNA levels of heat shock protein (HSP70), caspase-3, AMP-activated protein kinase (AMPK), heme-oxigenase (HMOX), and xanthine oxidoreductase (XOR). Dietary supplementation with NAC decreased the feed/gain, mortality rate, plasma corticosterone level, MDA concentration and intestinal mucosal mRNA levels of HSP70, AMPK and HMOX, while elevated the ratio of VH to CD, ATP, catalase (CAT) and trypsine activity in the small intestine of heat-stressed broilers. Taken together, these results suggest that dietary supplementation of 1 g/kg NAC could improve growth performance and intestinal function of broilers exposed to heat stress. © 2016 Elsevier B.V.

摘要：
Abstract There is growing interest in glutamate as a functional amino acid in nutrition and health. This study was conducted to determine whether glutamate precursor α-ketoglutarate (AKG) could alleviate lipopolysaccharide (LPS)-induced liver injury in young pigs. Twenty-four piglets were randomly assigned to the control, LPS, or LPS + AKG group. Piglets in the control and LPS groups were fed a basal diet, whereas piglets in the NAC group were fed the basal diet supplemented with 1 % AKG. On days 10, 12, 14, and 16 of the trial, piglets in the LPS and LPS + AKG groups received intraperitoneal administration of LPS (80 μg/kg BW), whereas piglets in the control group received the same volume of saline. On day 16 of the trial, blood samples were collected 3 h after LPS or saline injection. Twenty-four hours post-administration of LPS or saline (on day 17 of the trial), piglets were killed to obtain liver for analysis. Dietary AKG supplementation alleviated LPS-induced histomorphological abnormalities and mitigated LPS-induced increases in aspartate aminotransferase (AST) activity and AST/ALT ratio (P < 0.05). Compared with the LPS group, dietary supplementation with AKG decreased plasma glutamate concentration, while increasing hepatic concentrations of glutamate, glutamine, leucine, asparagine, lysine, alanine, serine, threonine, valine, and phenylalanine (P < 0.05). LPS challenge dramatically increased concentrations of malondialdehyde and decreased glutathione peroxidase activity in the liver. Additionally, LPS challenge enhanced concentrations of AMP and total protein, as well as RNA/DNA and total protein/DNA ratios, while decreasing hepatic ADP concentrations. These adverse effects of LPS challenge were ameliorated by AKG supplementation. Collectively, dietary AKG supplementation provides a new means to ameliorate LPS-induced liver injury by increasing anti-oxidative capacity and improving energy metabolism in young pigs. © 2015 Springer-Verlag Wien.

摘要：
为深入研究嗜酸乳杆菌的作用机理,以温敏型穿梭载体pSET4s为基本骨架,将绿色荧光蛋白（GFP）和嗜酸乳杆菌上、下游同源臂插入该载体,构建GFP标记的穿梭表达载体pSET4s-P1-GFP-P2。利用电转化方法将穿梭表达载体pSET4s-P1-GFP-P2转化入嗜酸乳杆菌,通过抗性和温度双重筛选获得能稳定表达GFP的重组嗜酸乳杆菌,将Western blotting和荧光显微镜观察验证的重组菌命名为ΔMG6243（GFP）。利用荧光显微镜观察和平板计数的方法对重组菌进行遗传稳定性和生物学特性研究。结果显示,重组菌在蓝光激发下可见明显绿色荧光,连传10代仍可见明显荧光,与野生菌相比,其生长特性、酸碱盐耐受性均无显著差别。结果表明,本试验已成功构建稳定表达GFP基因的重组嗜酸乳杆菌,利用温敏型穿梭载体pSET4s实现了外源基因在嗜酸乳杆菌中非抗性、整合型表达,为嗜酸乳杆菌基因重组菌的构建奠定了基础,同时GFP的标记作用也为嗜酸乳杆菌在动物体内分布、定植规律和作用机理创造了可行的条件。

摘要：
Neonates (including human infants) require l-glutamine (Gln) for optimal intestinal health. This study tested the hypothesis that Gln enhances enterocyte growth via both mammalian target of rapamycin (mTOR) and AMP-activated kinase (AMPK) signaling pathways. Intestinal porcine epithelial cells (IPEC-1) were cultured for 3 days in Gln-free Dulbecco's modified Eagle medium containing 0 or 2 mM Gln. To determine the role of mTOR and AMPK on cell growth, additional experiments were conducted where medium contained 2 mM Gln and 10 nM rapamycin (Rap, an inhibitor of mTOR) or 1 μM compound C (an inhibitor of AMPK). IPEC-1 cell growth increased with increasing concentrations of Gln from 0 to 2 mM. Compared with 0 mM Gln, 2 mM Gln increased (P < 0.05) the amounts of phosphorylated 4E-binding protein 1 (4E-BP1) and ribosomal protein S6 kinase (p70S6 kinase) proteins but did not affect abundances of total or phosphorylated AMPK protein. Gln also increased mRNA levels for Bcl-2, mTOR, p70S6 kinase, 4E-BP1, COX7C, ASCT2, ODC, SGLT-1, CFTR, Na+/K+-ATPase, HSP70, and ZO-1. Similarly, cells cultured with Rap and Gln exhibited higher (P < 0.05) abundances of phosphorylated 4E-BP1 and p70S6 kinase proteins than the Rap-only group, whereas abundances of phosphorylated mTOR and 4E-BP1 proteins were increased when AMPK was inhibited by compound C. Conversely, the amount of phosphorylated AMPK increased when mTOR was inhibited by Rap, suggesting a negative cross-talk between mTOR and AMPK. Collectively, these results indicate that Gln stimulates enterocyte growth by activating the mTOR signaling pathway independently of AMPK. © 2014 Springer-Verlag Wien.

摘要：
Cinnamon is a traditional herb used for treatment of many human diseases. The most important chemical compounds of the essential oil are cinnamaldehyde and eugenol. Oleum cinnamomi (OCM, cinnamon oil) is increasingly used as a feed additive to animal diets. Beneficial effects of OCM in protecting tissues from inflammation and injury by endogenous and exogenous agents (such as hydrogen peroxide and lipopolysaccharide (LPS)) may result, in part, from its action on regulating amino acid metabolism in cells to favor the synthesis of glutathione (a major low-molecular-weight antioxidant) from cysteine, glycine and glutamate. In support of this notion, results of recent studies indicate that supplementing OCM (50 mg/kg diet) to a corn- and soybean meal-based diet for piglets weaned at 21 days of age enhances intestinal anti-oxidative capacity and reduces the incidence of diarrhea. Additionally, dietary supplementation with OCM ameliorates LPS-induced mucosal barrier dysfunction and mucosal damage in the small intestine. OCM holds great promise for protecting the gut from injury under conditions of inflammation, infections, and oxidative stress. © 2015, Frontiers in Bioscience. All rights reserved.

摘要：
This study was carried out to investigate the effects of tributyrin (TB) on the growth performance, pro-inflammatory cytokines, intestinal morphology, energy status, disaccharidase activity, and antioxidative capacity of broilers challenged with lipopolysaccharide (LPS). A total of 160 one-day-old Cobb broilers were allocated to 1 of 4 treatments, with 4 replicated pens per treatment and 10 birds per pen. The experiment consisted of a 2×2 factorial arrangements of treatments with TB supplementation (0 or 500 mg/kg) and LPS challenge (0 or 500 μg/kg body weight [BW]). On days 22, 24, and 26 of the trial, broilers received an intraperitoneal administration of 500 μ g/kg BW LPS or saline. Dietary TB showed no effect on growth performance. However, LPS challenge decreased the average daily gain of broilers from day 22 to day 26 of the trial. Dietary TB supplementation inhibited the increase of interleukin-1β (in the jejunum and ileum), interleukin-6 (in the duodenum and jejunum), and prostaglandin E2 (in the duodenum) of LPS-challenged broilers. Similar inhibitory effects of TB in the activities of total nitric oxide synthase (in the ileum) and inducible nitric oxide synthase (in the jejunum) were also observed in birds challenged with LPS. Additionally, TB supplementation mitigated the decrease of ileal adenosine triphosphate, adenosine diphosphate and total adenine nucleotide and the reduction of jejunal catalase activity induced by LPS. Taken together, these results suggest that the TB supplementation was able to reduce the release of pro-inflammatory cytokines and improve the energy status and anti-oxidative capacity in the small intestine of LPS-challenged broilers.

摘要：
为考查N-乙酰半胱氨酸(NAC)是否可以改善肉鸭肝脏的能量代谢状况及组织抗氧化能力,试验选用90只1 d樱桃谷肉鸭,随机分成3个处理组:对照组(基础日粮)、500 mg/kg NAC组(基础日粮+500 mg/kg NAC)、1 000 mg/kg NAC组(基础日粮+1 000 mg/kg NAC),每组3个重复,每个重复10只鸭。试验期为3周(1~21日龄)。结果表明:与对照组相比,日粮添加500 mg/kg NAC显著提高了血浆、肝脏的过氧化氢酶(CAT)、超氧化物歧化酶(SOD)的活力及肝脏谷胱甘肽过氧化物酶(GSH-Px)的酶活力、三磷酸腺苷(ATP)、二磷酸腺苷(ADP)的含量和能荷(EC)值(P<0.05),显著降低了血浆丙二醛(MDA)和肝脏过氧化氢(H2O2)的含量及肝脏AMP/ATP值和肝脏低氧诱导因子1(HIF-1)、黄嘌呤氧化还原酶(XOR)的m RNA水平(P<0.05);1 000 mg/kg NAC组显著提高了血浆和肝脏CAT、SOD的活力及肝脏GSH-Px的酶活力、ATP的含量、EC值和AMPK-α1的m RNA水平(P<0.05),显著降低了血浆和肝脏H2O2的含量及肝脏MDA的含量、HIF-1、XOR的m RNA水平。表明NAC可以提高肉鸭的组织抗氧化能力、改善肝脏的能量代谢,这可能与NAC对AMPK-α1、HIF-1及XOR的基因表达调控有关。
