酵母抽提物协助酱油减盐后对其风味物质的影响研究

该研究通过使用酱香型酵母抽提物(YE)协助酱油减盐,并对减盐前后酱油风味物质的变化进行分析。结果表明,通过减少原油用量直接减盐20%和30%后,酱油的关键理化指标以及游离氨基酸、小分子肽和挥发性芳香成分等风味物质含量均相应损失20%和30%,酱油味也被明显稀释。而酱香型YE协助减盐20%和30%后酱油的游离氨基酸、小分子肽和挥发性芳香成分总量分别可达到减盐前的99.98%~100.78%、98.40%~99.03%和95.66%~97.13%,且酱油味得以恢复,从而实现了酱油的减盐不减味。

Tum or Necrosis Factor Expression in ArterialWallsof Diabetic Rats

Immunohistochemistry was used to detect tumor necrosis factor (TNF α) expression in arterial wall of diabetic rats. It was found that endothelial cells were swollen and markedly proliferative in these vessels and accordingly TNF α showed strong positive immunohistochemical reaction in endothelial cells or extracellular intimal matrix of such vessels, which might be caused by the expression and release of TNF α from monocytes and arterial wall cells stimulated by AGEs. These findings suggested that increased TNF α expression might be associated with vascular damage and remodeling in diabetes.

早期泌尿系感染T淋巴细胞亚群改变的临床研究

目的:探讨早期泌尿系感染T淋巴细胞亚群改变以帮助临床的早期诊断和治疗。方法:研究纳入2016年3~12月我院收治97例患者以及健康体检者26例,通过对各组外周血白细胞、中段尿白细胞计数、T淋巴细胞亚群计数和尿培养进行统计学差异以及ROC曲线分析,评价T淋巴细胞亚群对诊断早期泌尿系感染的敏感性、特异性。结果:根据外周血白细胞、中段尿白细胞、T淋巴细胞亚群计数以及中段尿细菌培养阳性结果分为4组,淋巴细胞亚群包括CD3+、CD4+、CD8+以及CD4+/CD8+比值对于泌尿系感染均有较高的敏感性和特异性,CD4+细胞诊断的敏感性和特异性最高,分别达到90%和80%。结论:T淋巴细胞亚群计数对于早期泌尿系感染的诊断具有明显的优势,从而可以帮助临床预防术后尿源性脓毒症的发生。
