早期认为神经胶质细胞相对惰性,看家细胞已经进化,神经胶质细胞现在被认为是动态细胞,不仅对神经元活动有反应,也能感知代谢变化,调节神经元代谢。这一演变在一定程度上得益于技术进步,使空间分辨率和时间分辨率逐步提高。细胞类型特异性遗传操作和亚细胞代谢探针的最新进展有望通过研究体内精细神经元和胶质细胞之间的代谢相互作用,进一步促进这种进化。在疾病过程中关于神经胶质细胞的观点也在进化。长期以来被认为是纯反应性的神经胶质细胞,特别是小胶质细胞,在促进和限制脑损伤方面起着积极的作用。同时,已建立的胶质能量学概念现在与学习和神经网络功能等领域联系在一起,这些主题以前被认为远离胶质细胞生物学。

目的:利用筛选出的一株能产D-阿拉伯糖异构酶(D-AI)的耐热菌株,将D-半乳糖转化为D-塔格糖。方法:从实验室保藏的菌株中筛选出一个产D-阿拉伯糖异构酶能力较强的苍白芽孢杆菌,将该菌株中的D-阿拉伯糖异构酶基因D-AI克隆到载体peT-28a上,并转化到大肠杆菌BL21(De.)中表达。通过SDS-PAGe.析发现,重组菌株能表达出大量可溶性蛋白。结果:D-阿拉伯糖异构酶纯化酶的最适反应pH值和温度分别是7.0和60℃,在pH6.0～8.0范围和30～70℃范围内具有较好的稳定性。加入Mn2+、Zn2+、Fe.+、Ca2+和Ba2+均能够使D-塔格糖的转化率提高,而Mg2+和Cu2+则对酶活力产生不同程度的抑制。结果表明:底物质量浓度为18g/L的D-半乳糖(含5mmol/L Mn2+),加入到pH值为7.0的重组细胞粗酶液中,在60℃条件下反应12h,可达到最高转化率为41.6%。结论:这表明具有生物活性的重组D-AI在大肠杆菌***(BL21)中成功表达且具备工业化生产D-塔格糖的潜能。

目的分析β2-微球蛋白(β2-microglobulin,β2-MG)与超敏C反应蛋白(hyperse.sitive.C-re.ctive.pro-te.n,hs-CRP)在早期2型糖尿病肾病(Type 2 diabe.ic ne.hropathy,T2DN)中的临床意义。方法回顾性分析2021年1—12月三明市中西医结合医院检验科收治的170例2型糖尿病患者临床资料,根据尿微量白蛋白检测率(microalbuminuria,m Alb)将其分为早期T2DN组(m Alb在30~300mg/g)75例与单纯2型糖尿病组(m Alb0.05)。采用Spearman相关性分析显示,早期T2DN组患者β2-MG、hs-CRP表达与m Alb呈正相关性(P<0.05)。结论β2-MG与hs-CRP在早期T2DN检测中具有一定的应用意义,且联合检测的价值更高,为后续临床诊疗工作提供了重要的参考指标。
