常规的光纤通信网络时延自动控制方法对通信干扰的抑制效果不佳,因此提出信号序列预测和缓冲区算法下光纤通信网络时延自动控制方法。建立预测目标函数,采用负载自适应调度方法对通信信号序列进行预测;基于缓冲区算法对光纤网络通信的密度进行计算;按照编码形式对通信密度进行分配;根据分配参数对通信干扰进行抑制;设置采样时间间隔对通信数据包进行分配,实现光纤通信网络时延控制。实验结果表明,本文设计的方法能够将光纤通信时延控制在0.89 ns之内,控制效果较好。

以樱桃谷鸭为原料,研究了烫皮过程温度变化和烫皮前后的水分、色泽、蛋白变性、显微结构等变化规律。结果表明:90~95℃,5 s的烫皮程度已达到传统烫皮感官要求,鸭皮表面温度到达80℃以上,皮内温度达到45℃以上;晾皮失水速度差异不显著(P>0.05),与鸭皮中的蛋白质变性程度测定(DSC)实验结果一致,显示该温度下蛋白发生变性、聚集。进一步探究90℃烫皮条件,结果表明,90℃烫皮7 s(90℃-7 s)晾皮3 h(含水量22.01%)比90℃烫皮9 s(90℃-9 s)晾皮4 h(含水量20.52%)膨化效果更好;DSC数据也显示90℃-7 s蛋白质热聚集程度大于烫皮5 s(P<0.05),90℃-9 s的样品蛋白质存在凝胶结构。综上所述,传统广式烤鸭鸭皮脆化与膨化的核心是控制烫皮后鸭皮中蛋白质处于变性聚集的状态及此状态下皮的水分含量,研究结果为探究传统广式烤鸭烫皮机理并为其烫皮工艺改良提供理论支持和技术参考。

消渴方(Xiaoke formula,XKF)是治疗消渴症的经典名方,具有改善胰岛素抵抗(insulin resistance,IR)作用,但其等效成分群(bioactive equivalent combinatorial components,BECC)目前尚不清楚。本研究基于团队前期研究基础,以小檗碱、黄芪甲苷、绿原酸作为消渴方BECC组成候选成分,探讨其药效和生物机制。采用高脂饮食诱导IR小鼠模型,检测消渴方及消渴方BECC给药后小鼠血糖、胰岛素敏感性、血脂代谢、免疫炎症因子等指标,采用病理切片染色检测组织病理改变,利用网络药理学预测消渴方及其BECC潜在作用靶点与信号通路,并用Western blot对网络药理学结果进行验证。动物福利和实验过程均遵循北京迈德康纳生物技术有限公司实验动物伦理委员会的规定(MDKN-2023-019)。结果显示,由小檗碱、黄芪甲苷、绿原酸按消渴方原方配比组成的消渴方BECC,在改善IR小鼠的血糖、胰岛素敏感性、组织病理损伤、血脂紊乱、免疫炎症等方面与消渴方作用相当;网络药理学和Western blot结果表明,消渴方及其BECC可能是通过促进肝脏磷脂酰肌醇3-激酶活化(PI3K)、蛋白激酶B(AKT)磷酸化,抑制肝脏糖异生关键限速酶葡萄糖-6-磷酸酶(G6PC)、磷酸烯醇式丙酮酸羧激酶1(PCK1)表达,最终实现改善IR。综上,小檗碱、黄芪甲苷、绿原酸可作为消渴方改善IR的潜在等效成分群,其通过调节脂质代谢、免疫炎症,促进IR小鼠肝脏PI3K/AKT通路信号传递,进而抑制肝脏糖异生途径,调节葡萄糖稳态改善IR。
