羊乳中蛋白质、脂肪、维生素及矿物质含量与牛乳相比更接近人乳,且更易消化吸收,而羊乳的膻味限制了其消费。研究指出,生物发酵方法可改善羊乳的膻味特征,提高感官品质。此外,微生物发酵过程中代谢产生短链脂肪酸、胞外多糖等功能性活性物质,并且伴随着羊乳中蛋白质降解,发酵产品中产生富含具有抗氧化作用、抗菌活性、ACE抑制活性等多种具有健康功效的活性肽,强化了发酵羊乳的价值。因此,采用微生物发酵方法生产营养丰富、口感独特的发酵酸羊乳是羊乳加工发展的重要方向。本文对羊乳发酵菌株及发酵工艺进行了总结分析,阐述了其对发酵羊乳口感、风味及功能活性的影响,并进一步综述了风味羊乳发酵制品创制的国内外研究现状及发展趋势,为健康美味的酸羊乳产品研发及推广提供了指导。

目的探索握力水平与心力衰竭患者预后的相关性。方法选取2015年6月至2017年6月于河北省唐山市中医医院就诊的心力衰竭患者560例,根据患者握力的三分位间距分为3组,组1:握力<18.9 kg(184例),组2:18.9 kg≤握力<23.5 kg(188例),组3:握力≥23.5 kg(188例)。中位随访时间3年,主要终点为全因死亡和心力衰竭再住院。采用Kaplan-Meier生存分析明确握力水平与终点事件的关系。采用多因素Cox回归方法分析握力与心力衰竭患者预后的相关性。使用亚组分析探究握力水平在不同心力衰竭类型人群中对心力衰竭再住院结局的影响。绘制局部加权回归(Lowess)曲线评估握力与心力衰竭再住院风险的关系。结果560例心力衰竭患者随访3年,共28例(5.0%)全因死亡,113例(20.2%)心力衰竭再住院。3组患者全因死亡发生率比较,差异无统计学意义(P=0.074),心力衰竭再住院发生率比较[25.0%(46/184)、21.3%(40/188)、14.4%(27/188)],差异有统计学意义(P=0.034)。生存分析结果表明,在随访过程中,随着握力的升高,患者心力衰竭再住院发生率明显降低(Log-rank P=0.034)。多因素Cox回归分析结果表明,在纳入更多混杂因素后,高握力水平患者心力衰竭再住院发生风险仍可显著降低(组3比组1,P=0.004)。针对不同类型心力衰竭的亚组分析结果显示,在射血分数降低型心力衰竭和射血分数保留型心力衰竭亚组中,高握力水平患者心力衰竭再住院发生风险显著降低(均P<0.05)。不同心力衰竭类型和握力分组之间无显著交互作用(交互P=0.568)。Lowess曲线表明,握力作为连续变量,与心力衰竭再住院的发生风险呈负相关。结论在心力衰竭患者中,高握力水平患者心力衰竭再住院的发生风险显著降低。

Multi-parameter hydrological gauge is an instrument developed by the South China Sea Institute of Oceanology, the Chinese Academy of Sciences to make simultaneous observation of current, wave, tide, water temperature and conductivity. By using the well-known ＂PUV method＂, the directional wave spectrum can be calculated and the dominant wave direction is then obtained. The comparison of the dominant wave directions derived from the measurements using both the multi-parameter hydrological gauge and the MARK Ⅱ ＂Wave-Rider＂ directional buoy shows that the dominant wave directions derived from the two kinds of measurements are in good agreement.
