目的

分析外周血磷脂酰肌醇-3-激酶(PI3K)/丝氨酸-苏氨酸特异性蛋白激酶(Akt)/哺乳动物雷帕霉素靶蛋白(mTOR)信号通路与急性缺血性脑卒中(AIS)静脉溶栓后出血转化(HT)的关系。

方法

选择自2022年6月至2024年5月于南通市海门区人民医院神经内科接受静脉溶栓治疗的260例AIS患者,根据溶栓后48 h头颅CT结果分为HT组(55例)和非HT组(205例)。对比2组患者的外周血PI3K、Akt、mTOR mRNA相对表达量及临床资料,多因素Logistic回归法分析AIS静脉溶栓后发生HT的影响因素,受试者工作特征(ROC)曲线分析外周血PI3K、Akt、mTOR mRNA相对表达量单独和联合预测AIS静脉溶栓后发生HT的价值。

结果

HT组患者的外周血PI3K mRNA、Akt mRNA、mTOR mRNA相对表达量低于非HT组,发病至溶栓时间、美国国立卫生研究院脑卒中量表(NIHSS)评分高于非HT组,差异均有统计学意义(P<0.05)。多因素Logistic回归分析显示,发病至溶栓时间、NIHSS评分及PI3K、Akt、mTOR mRNA相对表达量是影响AIS患者静脉溶栓后HT发生的独立危险因素(P<0.05)。PI3K、Akt、mTOR及三者联合预测AIS患者静脉溶栓后HT发生的ROC曲线下面积(95%CI)分别为0.772(0.582~0.952)、0.728(0.498~0.937)、0.680(0.395~0.957)、0.849(0.725~0.957),三者联合预测的价值最高。

结论

AIS静脉溶栓后HT患者的外周血PI3K/Akt/mTOR信号通路相关分子表达下调,该通路抑制会增加HT发生风险,联合检测外周血PI3K/Akt/mTOR信号通路相关分子对AIS静脉溶栓后发生HT具有较好的预测价值。

Objective

To analyse the relationship between the peripheral blood phosphatidylinositol-3-kinase (PI3K)/serine-threonine-specific protein kinase (Akt)/mammalian target of rapamycin (mTOR) signalling pathway and hemorrhagic transformation (HT) following intravenous thrombolysis in acute ischemic stroke (AIS).

Methods

Two hundred and sixty AIS patients at our hospital were chosen from June 2022 to May 2024, and given intravenous thrombolysis as a treatment. patients were divided into HT group (55 cases) and non-HT group (205 cases) according to the head CT results 48 h after thrombolysis. The peripheral blood PI3K, Akt, mTOR mRNA relative expression levels, clinical data, and laboratory indicators were compared between the two groups. the influencing factors of HT after AIS intravenous thrombolysis were analyzed by multivariate Logistic regression analysis, the peripheral blood PI3K, Akt, mTOR mRNA relative expression levels and the value of their combined prediction of HT after AIS intravenous thrombolysis were analyzed by receiver operating characteristic (ROC) curve.

Results

The relative expression levels of PI3K mRNA, Akt mRNA, and mTOR mRNA in peripheral blood of patients in the HT group were lower than those in the non-HT group, the time from onset to thrombolysis and the National Institutes of Health stroke scale (NIHSS) score in the HT group were higher than those in the non-HT group, with statistically significant differences (P<0.05). Multivariate Logistic regression analysis revealed that the time from symptom onset to thrombolysis, NIHSS score, and the relative expression levels of PI3K, Akt, and mTOR mRNA were independent risk factors for the occurrence of HT after intravenous thrombolysis in AIS patients (P<0.05). The areas under the ROC curve (95%CI) of PI3K, Akt, mTOR, and their combined prediction of HT following intravenous thrombolysis in AIS were 0.772 (0.582-0.952), 0.728(0.498-0.937), 0.680(0.395-0.957) and 0.849(0.725-0.957), respectively, with the combination of the three having the highest predictive value.

Conclusions

The peripheral blood PI3K/Akt/mTOR signalling pathway relative expression levels reduce of HT following intravenous thrombolysis in AIS, and inhibition of this pathway increases the risk of HT, the combined detection of peripheral blood PI3K/Akt/mTOR signaling pathway relative has good predictive value for intravenous thrombolysis in AIS.
