Effects of dietary supplementation with fructooligosaccharides on the excretion of nitrogen and phosphorus in Miichthys miiuy fries were investigated. Nine hundred Miichthys miiuy fries were divided into 3 groups, each with triplicates. The basal diet and the basal diet supplemented with carnitine groups were considered as the negative and positive controls respectively. Results showed that the nitrogen concentration in excreted feces decreased significantly in fries fed the diet supplementation with 1000 x 10(-6) fructooligosaccharides and 200 x 10(-6) carnitine (P<0.05). The ammonic-nitrogen concentration decreased significantly in the carnitine group only (P<0.05), indicating the decreasing tendency caused by the supplementation with fructooligosaccharides. Supplementation with both did not have significant effects on the concentration of phosphorus in feces of Miichthys miiuy fries.

OBJECTIVETo study the effect of a low level of galacto-oligosaccharides (GOS) on intestinal bifidobacteria and lactobacilli, and fermentation characteristics in term infants by comparing with human milk and a standard infant formula without GOS.
METHODSA total of 371 term infants from four hospitals of China were enrolled. The infants started with breast feeding. After 1-2 weeks, some of the infants were changed to feeding with formula milk and then were randomly assigned to two formula-feeding groups: with or without GOS supplementation (2.4 g/L). Growth, stool characteristics, and side effects were recorded in a 3-month-follow-up. Faecal samples were collected for analysis of intestinal bacteria (culture technique), acetic acid (gas chromatography) and pH (indicator strip) at postnatal 3 months.
RESULTSCompared with the formula-feeding group without GOS, the contents of bifidobacteria, lactobacilli and acetic acid and stool frequency increased, and faecal pH decreased significantly in the GOS-formula-feeding and the human milk group. There were no significant differences between the GOS-formula-feeding and the human milk groups. Supplementation with GOS did not lead to an increase in the incidence of crying, regurgitation and vomiting.
CONCLUSIONSA supplementation of low levels of GOS in infant formula seemed to improve stool frequency, decrease faecal pH, and stimulate intestinal bifidobacteria and lactobacilli up to levels as found in breast-fed infants.

BACKGROUNDOligosaccharides in human milk may protect infants by improving the intestinal micro-flora and fermentation. This study was to investigate effects of infant formula milk consisting of galacto-oligosaccharide (GOS) on intestinal microbial populations and the fermentation characteristics in term infants in comparison with that of human milk.
METHODSThe test formula (Frisolac H, Friesland, Netherland) was supplemented with GOS at a concentration of 0.24 g/dl. Human milk and another formula without oligosaccharides (Frisolac H, Friesland, Netherland) were used as positive and negative control respectively. Growth, stool characteristics, and side effects of the recruited infants were recorded after 3 and 6 months' follow-up, and the fecal species were collected for the analysis of intestinal micro-flora, short chain fatty acid (SCFA) and pH.
RESULTSAt the end of 3- and 6-month feeding period, intestinal Bifidobacteria and Lactobacilli were significantly increased in infants fed with GOS supplemented formula and human milk when compared with infants fed with negative control formula; however, there was no statistically significant difference between GOS supplemented formula and human milk groups. Stool characteristics were influenced by the supplement and main fecal SCFA (acetic), and stool frequency were significantly increased in infants fed with GOS supplemented formula and human milk, while the fecal pH was significantly decreased as compared with that of negative control (P < 0.05). Supplementation had no influence on incidence of side effects (including crying, regurgitation and vomiting).
CONCLUSIONSSupplementing infant formula with GOS at a concentration of 0.24 g/dl stimulates the growth of Bifidobacteria and Lactobacilli in the intestine and stool characteristics are similar to in term infants fed with human milk.

4.Oligosaccharide and creatine supplementation on glucose and urea nitrogen in blood and serum creatine kinase in basketball athletes.
Journal of Huazhong University of Science and Technology (Medical Sciences) 2005;25(5):587-9
The effects of oligosaccharide and creatine (Cr) supplementation on glucose, lactic acid and urea nitrogen levels in blood and activity of serum creatine kinase (CK) were explored. Twenty CUBA male athletes were divided into 4 groups: group A (supplementation of Cr alone), group B (supplementation of oligosaccharide), group C (supplementation of oligosaccharide and Cr) and group D (placebo control group). By using orthogonal L4 table (2(3)), the experiment was performed. There were factors including oligosaccharide (carbohydrate, CHO), Cr and their correlation. Each factor had two levels: supplementation and no-supplementation. The results showed that the supplementation of CHO or Cr alone, combined supplementation of CHO and Cr could significantly reduce the glucose, urea nitrogen levels in blood and serum CK activity after competition in the athletes. Moreover, the effects of combined supplementation of CHO and Cr were more satisfactory. It was concluded that supplementation of CHO and Cr could promote the recovery of physical performance and athletic abilities after athletics in basketball athletes.

AIMTo prepare the micelles of stearic acid-grafted chitosan oligosaccharide and investigate the drug release from micelles.
METHODSMediated by a 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC), stearic acid (SA) was covalently attached to chitosan oligosaccharide (CSO), and the graft polymer (CSO-SA) was obtained. The critical aggregation concentration (CAC) of the CSO-SA was determined by measuring the fluorescence intensity of pyrene as a fluorescent probe. The effect of various pH dispersed media and concentration of tripolyphosphate sodium (TPP) on the micellar size distribution and zeta-potential measured by light scattering and electrophoretic mobility, was investigated. In buffers of different pH, the release profiles of methotrexate (MTX) from micelles were evaluated.
RESULTSThe CAC value of CSO-SA in deionized water was 0.05 g x L(-1). The mean diameter of CSO-SA micelles was 26.7 nm and the zeta potential was (55.9 +/- 0.1) mV. With the increase of TPP concentration, the size and MTX encapsulation of CSO-SA micelles increased, while the zeta-potential decreased. With the decrease of pH value of dispersed media, the size and zeta-potential of CSO-SA micelles increased, and the MTX encapsulation in CSO-SA micelles decreased. While the enhancement of drug release from the micelles was observed.
CONCLUSIONThe graft polymer of CSO-SA provides polymeric micelles, which possessed a low CAC value in aqueous media. The drug release in vitro from CSO-SA micelles was affected by the pH of delivery media.

6.Comparison of Gefitinib versus Docetaxel in Patients with Pre-Treated Non-Small Cell Lung Cancer (NSCLC).
Journal of Lung Cancer 2009;8(2):61-66
More effective treatments in first, second, and third-line of metastatic non-small cell lung cancer (NSCLC) enable patients to live longer, with a better quality of life (QOL). Especially epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) contributed to this improvement. Gefitinib was compared with Docetaxel in four randomized trials, i.e., SIGN, Japanese V-1532, Korean ISTANA, and INTEREST in second or third-line treatment of metastatic NSCLC. In all the trials, and also by meta-analysis of 2,257 patients in these trials, Gefitinib was found non-inferior or superior to Docetaxel, with less toxicity, convenient oral administration, and better QOL. Detailed results are presented in the review article. Knowing that every line of treatment we may lose about 50% of patients for further treatment, it is very important to offer each patient the best option for every line of treatment. Gefitinib has a favorable benefit-risk profile compared with Docetaxel in this patient population.

BACKGROUND/OBJECTIVES: Constipation is a condition that can result from intestinal deformation. Because humans have an upright posture, the effects of gravity can cause this shape deformation. Oligosaccharides are common prebiotics and their effects on bowel health are well known. However, studies of the physiological functionality of a product that contains both lactulose and galactooligosaccharides are insufficient. We investigated the constipation reduction effect of a dual-type oligosaccharide, Dual-Oligo, in loperamide-treated rats. MATERIALS/METHODS: Dual-Oligo consists of galactooligosaccharides (15.80%) and lactulose (51.67%). Animals were randomly divided into four groups, the normal group (normal), control group (control), low concentration of Dual-Oligo (LDO) group, and high concentration of Dual-Oligo (HDO) group. After 7 days of oral administration, fecal pellet amount, fecal weight, water content of fecal were measured. Blood chemistry, short-chain fatty acid (SCFA), gastrointestinal transit ratio and length and intestinal mucosa were analyzed. RESULTS: Dual-Oligo increased the fecal weight, and water content of feces in rats with loperamide-induced constipation. Gastrointestinal transit ratio and length and area of intestinal mucosa significantly increased after treatment with Dual-Oligo in loperamide-induced rats. A high concentration of Dual-Oligo tended to produce more acetic acid than that observed for the control group, and Dual-Oligo affected the production of total SCFA. Bifidobacteria concentration of cecal contents in the high-concentration oligosaccharide (HDO) and low-concentration oligosaccharide (LDO) groups was similar to the result of the normal group. CONCLUSIONS: These results showed that Dual-Oligo is a functional material that is derived from a natural food product and is effective in ameliorating constipation.

OBJECTIVETo investigate the influence of Rehmannia glutinosa oligosaccharides (ROS) on the proliferation of 3T3-L1 adipocytes and insulin resistance.
METHOD3T3-L1 preadipocytes were cultured, the proliferation of 3T3-L1 preadipocytes was detected by MTT method. Insulin resistant 3T3-L1 adipocytes cell model was induced by dexamethasone and the change of glucose concentration in cell culture was determined after ROS treatment.
RESULTIn the high glucose DMEM culture media, MTT method showed that the absorbance at 570nm of 3T3-L1 preadipocytes was increased and that of 3T3-L1 adipocytes was decreased. ROS significantly increased glucose consumption in 3T3-L1 preadipocytes and adipocytes culture in a concentration-dependent manner. ROS improved the sensitivity of 3T3-L1 adipocytes to insulin.
CONCLUSIONROS can promote the proliferation of 3T3-L1 preadipocytes, inhibite the proliferation of 3T3-L1 adipocytes, and also, significantly improve insulin resistance induced by dexamethasone.

BACKGROUND/AIMS: Race and ethnicity are important determinants when estimatingglomerular filtration rate (GFR). The Korean coefficients for the isotope dilution mass spectrometry (IDMS) Modification of Diet in Renal Disease (MDRD) Study equations were developed in 2010. However, the coefficients have not been validated. The aim of this study was to validate the performance of the Korean coefficients for the IDMS MDRD Study equations. METHODS: Equation development and validation were performed in separate groups (development group, n = 147 from 2008 to 2009; validation group, n = 125 from 2010 to 2012). We compared the performance of the original IDMS MDRD equations and modified equations with Korean coefficients. Performance was assessed by comparing correlation coefficients, bias, and accuracy between estimated GFR and measured GFR, with systemic inulin clearance using a single injection method. RESULTS: The Korean coefficients for the IDMS MDRD equations developed previously showed good performance in the validation group. The new Korean coefficients for the four- and six-variable IDMS MDRD equations using both the development and validation cohorts were 1.02046 and 0.97300, respectively. No significant difference was detected for the new Korean coefficients, in terms of estimating GFR, between the original and modified IDMS MDRD Study equations. CONCLUSIONS: The modified equations with Korean coefficients for the IDMS MDRD Study equations were not superior to the original equations for estimating GFR. Therefore, we recommend using the original IDMS MDRD Study equation without ethnic adjustment in the Korean population.
