[目的]研究银杏二萜内酯(GDL)对糖尿病大鼠视网膜病变的影响,并基于Toll样受体4/核因子-κB(TLR4/NF-κB)信号通路探索其可能的作用机制。[方法]采用高糖高脂饮食加腹腔注射30 mg/kg链脲佐菌素(STZ)的方法构建糖尿病视网膜病变大鼠模型,设模型组、GDL(2.3 mg/kg)组、TAK242(TLR4抑制剂,3 mg/kg)组、GDL+TAK242(2.3 mg/kg+3 mg/kg)组;另设正常对照组。各组分别每日1次腹腔注射给药治疗14 d后,测定空腹血糖(FBG)水平、视网膜厚度和视网膜血管通透性,通过苏木精-伊红(HE)染色、TUNEL染色观察视网膜病理改变和细胞凋亡,酶联免疫吸附测定(ELISA)法检测视网膜炎症因子[白细胞介素-1β(IL-1β)、IL-6、IL-8、肿瘤坏死因子-α(TNF-α)]含量,Western blot法检测视网膜TLR4、NF-κB、p-NF-κB、NF-κB抑制因子(IκBα)、p-IκBα、高迁移率族蛋白B1(HMGB1)、B淋巴细胞瘤-2基因(Bcl-2)、Bcl-2相关X蛋白(Bax)表达。[结果]与模型组相比,GDL组、TAK242组和GDL+TAK242组FBG水平和血管通透性降低,视网膜厚度增加(P<0.05);视网膜神经节细胞层和内核层细胞数目减少、排列紊乱、分层不清、水肿、炎性浸润等病理改变明显减轻,细胞凋亡状况明显改善;视网膜IL-1β、IL-6、IL-8、TNF-α含量明显降低(P<0.05),TLR4、p-NF-κB、p-IκBα、HMGB1、Bax表达量及p-NF-κB/NF-κB、p-IκBα/IκBα、Bax/Bcl-2比值降低(P<0.05),Bcl-2表达量升高(P<0.05)。GDL+TAK242组对糖尿病大鼠上述指标的调控作用明显优于GDL组和TAK242组(P<0.05)。[结论]GDL可抑制糖尿病大鼠视网膜炎症反应和细胞凋亡,降低视网膜血管通透性,减轻视网膜病理改变,其机制可能与抑制TLR4/NF-κB信号通路活化有关。

目的探讨电子配血技术应用对减少受血者Rh血型同种抗体产生的意义。方法将本院2018年1月1日-2020年3月31日期间住院且仅输注去白悬浮红细胞的Rh(D)阳性的患者22 528人,将电子配血符合优先级Ⅰ级、Ⅱ级的患者21 334人设为对照组,将符合优先Ⅲ级的患者共1 194人设为试验组,对用血者和献血者进行ABO和Rh血型系统5种抗原(D、C、c、E、e)的血清学检测,并运用输血管理系统,建立Rh表型数据库。并对对照组和试验组进行输注红细胞过程中引入新的抗原相对应不规则抗体的产生率进行比较。结果 C抗原和e抗原所占的比例明显高于c和E抗原。同时表现型为DCCee和DCcEe的比率最高,表现型为Dccee和DCCEE的极为罕见。在本院输血患者达到优先Ⅰ级(85.2%)和Ⅱ级(9.5%)输血标准的比例达到94.7%,达优先Ⅲ级的输血比例仅为5.3%。对照组(n=21 334)中患者输血后产生Rh系统同种抗体共6人,比率小于0.001%;试验组(n=1 194)中患者输血后共24人出现与引入外来抗原相符的Rh系统同种抗体,比率为2.01%。试验组与对照组差异存在临床意义(P<0.01)。结论依据Rh抗原检测的电子配血技术可明显降低输血后Rh血型系统不规则抗体阳性率,从而有效的保证临床输血安全。
