Soybean protein has high nutritional value, but its functional properties are easily affected by external factors,which limits its application in food industry. In the study, soybean protein isolate(SPI) was modified by dry heat glycation of galactooligosaccharides(GOS). The gel properties, antioxidant properties and structural changes of SPI-GOS conjugates were investigated. The application of SPI-GOS conjugates in noodles was also explored. The results observed that the glycation degree of SPI increased with the increasing reaction time. SDS-PAGE and spectral analysis showed the changes of spatial conformation of SPI after glycation. The antioxidant activity of SPI increased after glycation and DPPH radical scavenging activity of SPI-GOS peaked at 48 h of reaction. The hardness, elasticity and resilience of soybean protein gel reached their relative maximum at 48 h, 48 h and 12 h of glycation reaction, respectively. Moreover, the appropriate addition of glycated SPI improved the quality of noodles. The noodles with 4% addition of SPI-GOS had higher hardness, elasticity and tensile properties. This study will provide an effective method to modify soybean protein and expand the use of soybean protein in food industry.

利用木瓜蛋白酶有限酶解花生分离蛋白,再与葡聚糖在80℃下进行湿法糖基化反应2~6 h,研究糖基化对花生分离蛋白酶解物结构及功能特性的影响。结果表明,糖基化反应后花生分离蛋白酶解物具有较高的接枝度,紫外光谱和内源荧光光谱表明其空间结构发生改变,傅里叶变换红外光谱结果证实花生分离蛋白酶解物与葡聚糖发生糖基化反应。通过对复合改性后花生分离蛋白功能特性进行评价,发现花生分离蛋白的溶解度在pH3~7内均有所改善,反应4 h的糖基化产物在pH7时溶解度达到最高,为91.56%,较相同pH值下的花生分离蛋白提高1.77倍。经过4 h的接枝反应后花生分离蛋白酶解物的乳化活性最高,达到61.08 m^(2)/g,较花生分离蛋白提高5.28倍。此外,有限酶解和糖基化反应能够明显降低花生分离蛋白的表面疏水性、提高花生分离蛋白的抗氧化活性。因此,通过酶解和糖基化复合改性能够有效改善花生蛋白的功能特性,扩大其应用范围。

目的观察补肾活血法联合腹腔镜治疗反复种植失败(RIF)合并子宫内膜异位症(EMs)的临床疗效。方法将72例RIF合并EMs患者按照随机数字表法分为2组,对照组36例予腹腔镜治疗,治疗组36例在对照组治疗基础上联合补肾活血法治疗。比较2组子宫内膜异位症分期(r-AFS分期);比较2组中医证候积分;比较2组中医疗效;比较2组内膜转化日子宫内膜厚度;比较2组胚胎移植后血清人绒毛膜促性腺激素(β-hCG);比较2组妊娠结局;比较2组治疗前后实验室指标变化。结果2组年龄、体质量指数(BMI)、不孕病程、不良妊娠次数、移植失败次数比较差异均无统计学意义(P>0.05),具有可比性。2组r-AFS分期比较差异无统计学意义(P>0.05)。2组治疗后中医证候积分均较本组治疗前降低(P0.05)。2组治疗后NK细胞比例均较本组治疗前降低(P0.05)。治疗后治疗组IL-6较本组治疗前降低(P<0.05)。结论补肾活血法联合腹腔镜治疗RIF合并EMs,能有效改善患者中医证候积分和子宫内膜厚度,减少NK细胞比例,降低TNF-α、IL-6水平,但对IL-10无明显影响。单纯腹腔镜治疗及中药联合腹腔镜治疗均能一定程度上提高胚胎种植率、临床妊娠率、持续妊娠率,其中中药联合腹腔镜治疗更有优势且流产率更低。

目的探讨上海市松江区居民生活方式对脑卒中风险的影响在不同年龄段中是否存在差异。方法选取上海郊区自然人群队列和生物样本库中松江区的31771名研究对象,计算其健康生活方式评分(包括不吸烟、积极体育锻炼、均衡膳食和正常体重),并随访至2021年12月31日。分别采用Cox比例风险回归和泊松回归评估不同基线年龄组和暴露年龄组中不同的生活方式或健康生活方式评分与新发脑卒中的HR值(95%CI)和RR值(95%CI)。基线年龄分层:年轻组(20~<62岁)、中年组(62~<68岁)以及老年组(≥68岁)。暴露年龄分层:年轻组(20~<65岁)、中年组(65~<70岁)以及老年组(≥70岁)。结果在5.0年的中位随访时间内共新发488例脑卒中事件。控制混杂变量后,两种方法都未发现不吸烟、积极体育锻炼、均衡膳食和正常体重与脑卒中发病风险的关联在不同的年龄组有显著差异。与基线生活方式评分≤1分组相比,年轻组、中年组及老年组中评分≥3分组的新发脑卒中风险较低(HR=0.67,95%CI:0.43~1.03,P=0.072;HR=0.59,95%CI:0.39~0.91,P=0.015;HR=0.64,95%CI:0.42~1.00,P=0.043和RR=0.63,95%CI:0.42~0.96,P=0.028;RR=0.61,95%CI:0.40~0.94,P=0.023;RR=0.63,95%CI:0.40~0.99,P=0.045)。结论在上海市松江区居民中没有发现不同的生活方式与脑卒中的关联存在年龄差异。提示在任何年龄阶段都应重视健康的生活方式。当整体的生活方式比较健康时可大幅度降低脑卒中发病风险。
