挪威鱼饲料生产公司Skretting公司将X射线与核磁共振成像技术应用到了鱼用颗粒饲料生产中,再结合饲料方面的专业软件,这些技术可揭示饲料颗粒结构与微孔的内在秘密,以及饲料中的次要成分对颗粒饲料的影响方式.通过专门开发的软件,该公司能够创建饲料颗粒的3D图像.通过观察真空包膜前后的饲料颗粒,可以对颗粒的内部结构、颗粒中微孔的大小以及颗粒大小的变化等有一个全面的了解.

目前,由广西贵港市港南区共展饲料厂生产加工的两批重510t、货值15.36万美元的饲料用水解羽毛球粉,经检验检疫合格隍顺利出口菲律宾,黎巴嫩.

为促进蛋白吸收率,提高饲料报酬,对15头不同产奶期奶牛进行改性蛋白饲喂,通过对比不同产奶期奶牛对改性蛋白的利用,得到改性蛋白对泌乳牛产奶量的影响.结果表明:改性蛋白对于泌乳牛产奶量影响不显著,但对于泌乳牛体况改善有显著成效,而且对于粪便质量改善较大.

为了确定奶牛日粮中复合处理玉米秸与苜蓿及精料的最佳组合,将复合处理玉米秸与苜蓿、复合处理玉米秸与精饲料以及筛选出的复合处理玉米秸与苜蓿的最优组合与精饲料均以0:100、20:80、40:60、60:40、80:20、100:0的比例进行组合,通过短期人工瘤胃技术测定饲料不同组合对瘤胃发酵的影响.结果表明,各不同组合对瘤胃液pH影响均不显著(P>0.05);对氨氮浓度影响显著或极显著(P< 0.05或P<0.01),但均在正常范围内.在微生物蛋白产量方面,复合处理玉米秸与苜蓿及复合处理玉米秸与精饲料比例为80:20的组合均极显著高于其他比例的组合(P<0.01),复合处理玉米秸与苜蓿的最优组合(80:20)与精饲料比例为60:40的组合极显著或显著高于其他比例的组合(P< 0.01或P<0.05).在乙酸浓度和三种挥发性脂肪酸总浓度上,复合处理玉米秸与苜蓿、复合处理玉米秸与精饲料及复合处理玉米秸与苜蓿的最优组合(80:20)与精料均以比例为60:40和80:20的组合极显著或显著高于其他比例的组合(P< 0.01或P<0.05).除精料比例为80%和100%的组合外,所有组合的乙酸丙酸比均在正常范围内.由此可见,在本试验设计条件下,奶牛日粮中复合处理玉米秸与苜蓿比例为80:20的组合、复合处理玉米秸与精饲料比例为80:20的组合以及复合处理玉米秸与苜蓿的最优组合(80:20)与精饲料比例为60∶40的组合为最佳组合.

患者,21岁,1年前发现左侧睾丸肿大,无疼痛、瘙痒等.外院行穿刺活组织检查,结果倾向支持细胞瘤,无睾丸外伤、隐睾等病史.体检:外生殖器发育正常.左侧睾丸可触及一实性肿物,大小2 cm*2 cm*1.5 cm,质硬,无压痛、粘连、周围淋巴结肿大、男性乳腺发育等其他异常体征.彩超示:左侧睾丸大小4.23 cm*2.01 cm,中上部见实性低回声团块,大小1.94*1.6 mm,内部回声不均匀,边界尚清,形态不规

目的:探讨黄芪颗粒在预防过敏性紫癜(HSP)患儿肾损害中的作用.方法:将96例HSP患儿随机分成治疗组48例和对照组48例,两组均予以维生素C、西咪替丁、芦丁片、葡萄糖酸钙和低分子肝素钠等综合治疗,治疗组在此基础上加用口服黄芪颗粒3个月.对两组患儿随访6个月,观察两组患儿症状消退时间,动态监测两组患儿尿常规、尿m-Alb和尿NAG酶的变化,分析两组患儿肾损害发生时间和发生率.结果:治疗后治疗组患儿症状消退时间明显短于对照组,两组比较差异有统计学意义(P〈0.05);随访6个月,不同时间点治疗组患儿尿常规异常例数少于对照组,差异均有统计学意义(P〈0.05);不同时间点治疗组患儿尿m-Alb和尿NAG酶水平低于对照组,差异有统计学意义(P〈0.05);治疗组肾损害发生时间晚于对照组,发生率低于对照组,差异均有统计学意义(P〈0.05).结论:黄芪颗粒治疗HSP,能降低肾损害的发生率,改善HSP的预后,具有积极的临床意义.

可视化过程建模语言VPML(Visual Process Modeling Language)的建模功能全面但建模过程复杂,故需进行建模功能分解.文中给出分解依据及结果表示方法,分解建模功能得出顶层功能集,并细化及用用例图表示各个功能集,直观形象地展示了系统与用户的交互,为企事业过程建模工具的设计和开发奠定了基础.
