Tomato was immersed into the sugar solution with the concentrations of 40%, 50% and 60% for 24 hours. Moisture, ash, protein, fat, vitamin C, acidity, total sugar, crude fiber, total SO2 and salt content and organoleptic quality and microbiological status of the prepared candy were analyzed. There was a tendency of decreasing moisture, ash, protein, fat, vitamin C, acidity, crude fiber and increasing total sugar content with increased concentration of sugar solution used. On the microbiological analysis, total bacteria and total fungus load were increased with increasing the concentration of sugar solution. The best characteristic of tomato candy was found with 40% sugar solution, with highest nutrient and sensory score and lowest microbial load than candy prepared with 50% and 60% sugar solution.展开更多
目的了解IGT患者口服葡萄糖耐量试验后的血脂变化情况,探讨糖负荷后血脂及其与胰岛素抵抗的关系。方法选自我院IGT患者100例。测定空腹血浆葡萄糖、HbA lc、空腹胰岛素、总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、高密...目的了解IGT患者口服葡萄糖耐量试验后的血脂变化情况,探讨糖负荷后血脂及其与胰岛素抵抗的关系。方法选自我院IGT患者100例。测定空腹血浆葡萄糖、HbA lc、空腹胰岛素、总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)后,给与75 g葡萄糖行口服葡萄糖耐量试验(OGTT),测定糖负荷后60分、120分和180分的血浆葡萄糖、胰岛素、TC、TG、LDL-C、HDL-C。并计算胰岛素抵抗指数(Hom a-IR)及负荷后血脂曲线下面积(Y-AUC)。结果糖负荷后60 m in、120 m in、180 m in的TG、HDL-C、LDL-C和TC浓度明显低于空腹各血脂浓度。Hom a-IR与TG(三个时段)呈正相关,Hom a-IR与HDL-C(三个时段)呈负相关,此外,Hom a-IR与其它血脂成分比较无统计学意义。结论IGT患者糖负荷血脂浓度较空腹时低,但Homa-IR与TG(三个时段)关系密切。提示合理应用调脂药物,改善胰岛素抵抗不但有利于血糖控制,也有利于血脂代谢的改善,从而延缓心血管疾病合并症的发生。展开更多

The chemical oxygen demand （COD） removal reached above 92.0% at organic loading rates （OLRs） of 12.0-54.0 kgCOD/（m^3· d）. The volatile lhtty acids （VFAs） in effluent were increased to 451.1 mg/L from 147.9 mg/L and the specific methane production rate improved by 1.2 2.2-1bid as the OLR increased. The evolution of microbial comnmnities in anaerobic sludge at three different OLRs was investigated using pyrosequencing. Operational taxonomic units （OTUs） at a 3% distance were 353,337 and 233 for OLRI2, OLR36 and OLR54, respectively. When the OLR was increased to 54.0 kgCOD/（m^3· d） from 12.0 kgCOD/ （m^3· d） by stepwise, the microbial community structure were changed significantly. Five genera （Bacteroides, Trichococcus, Cho,seobacterium, Longilinea and Aerococcus） were the dominant fermentative bacteria at the OLR 12-0 kgCOD/（m^3· d）. However, the sample of OLR36 was dominated by Lacmcoccus, Trichococcus, Anaer-arcus and Veillonella. At the last stage （OLR = 54.0 kgCOD/ （m^3· d）, the diversity and percentage of femlentative bacteria were markedly increased. Apart from fermentative bacteria, an obvious shift was observed in hydrogen-producing acetogens and non- acetotrophic methanogens as OLR increased. Svntrophohacter, Geobacter and Methanomethylovor- ans were the dominant hydrogen-producing acetogens and methylotrophic methanogens in the samples of OLRI2 and OLR36. When the OLR was increased to 54.0 kgCOD/（m^3· d）, the mare hydrogen-producing acetogens and hydrogenotrophic methanogens were substituted with Destd/bvi- brio and Methanospillum. However, the composition of acetotrophic methanogens （Methanosaeta） was relatively stable during the whole operation period of the UASB reactor.展开更多
