摘要:

目的探讨颅脑超声联合血清长链非编码RNA(long non-coding RNA,lncRNA)生长停滞特异性转录本5(growth arrest-specific transcript 5, GAS5)对新生儿脑损伤的诊断价值。方法收集2019年1月—2021年9月郑州大学附属儿童医院分娩的脑损伤高危新生儿162例为研究对象,根据高危新生儿脑损伤情况,分为观察组(存在脑损伤,92例)和对照组(无脑损伤,70例)。所有新生儿均接受颅脑超声检查。采用实时荧光定量PCR检测血清中GAS5表达水平。检测血清脑源性神经营养因子(brain-derived neurotrophic factor, BDNF)、血清胶质纤维酸性蛋白(glial fibrillary acidic protein, GFAP)水平。用Pearson法分析血清GAS5水平与BDNF、GFAP相关性。采用受试者工作特征(ROC)曲线评价血清GAS5水平诊断新生儿脑损伤的早期价值,分析颅脑超声联合血清GAS5对新生儿脑损伤的早期诊断价值。结果观察组经颅脑超声检测诊断出79例脑损伤,超声检查阳性率为85.87%,其中超声显示颅内出血34例,脑水肿22例,脑白质损伤18例。早产儿颅内出血、脑白质损伤发生率高于足月儿,足月儿脑水肿发生率高于早产儿,差异有统计学意义(P< 0.05)。与对照组相比,观察组血清GAS5相对表达水平、GFAP水平较高,BDNF水平较低,差异有统计学意义(P< 0.05)。Pearson分析显示,血清GAS5表达水平与BDNF呈负相关(P< 0.05),与GFAP呈正相关(P< 0.05)。颅脑超声异常组血清GAS5水平高于颅脑超声正常组,差异有统计学意义(P< 0.05)。颅脑超声检查联合血清GAS5检测在新生儿脑损伤早期诊断中准确度为90.12%,灵敏度为94.57%,特异度为84.29%,颅脑超声检查联合血清GAS5检测诊断重度脑损伤准确度为84.81%。结论血清GAS5在新生儿脑损伤中表达上调,颅脑超声联合血清lncRNA GAS5检测对新生儿脑损伤具有早期诊断价值。

Abstract:

ObjectiveTo investigate the diagnostic value of craniocerebral ultrasound combined with serum long non-coding RNA (lncRNA) growth arrest-specific transcript 5 (GAS5) in neonatal brain injury.MethodsA total of 162 high-risk neonates delivered in the Affiliated Children's Hospital of Zhengzhou University from January 2019 to September 2021 were collected as the research objects. According to the situation of brain injury, they were divided into the observation group (92 cases with brain injury) and the control group (70 cases without brain injury). All neonates underwent cranial ultrasonography. The expression level of GAS5 in serum was detected by real-time fluorescence quantitative PCR. Serum levels of brain-derived neurotrophic factor (BDNF) and glial fibrillary acidic protein (GFAP) were detected. The correlation between serum GAS5 level and BDNF and GFAP was analyzed by Pearson method. The value of serum GAS5 level in the diagnosis of neonatal brain injury was evaluated by Receiver Operating Characteristic (ROC) curve, the early diagnostic value of craniocerebral ultrasound combined with serum GAS5 in neonatal brain injury was analyzed.Results79 cases of brain injury were diagnosed by brain ultrasound in the observation group, and the positive rate of ultrasonography was 85.87%. Among them, 34 cases of intracranial hemorrhage, 22 cases of cerebral edema, and 18 cases of cerebral white matter injury were detected by ultrasonography. The incidences of intracranial hemorrhage and white matter injury in preterm infants were higher than those in full-term infants, and the incidence of cerebral edema in full-term infants was higher than that in preterm infants (P< 0.05). Compared with the control group, the relative expression level of serum GAS5 and the level of GFAP in the observation group were higher, the level of BDNF was lower (P< 0.05). Pearson method analysis showed that the expression level of serum GAS5 was negatively correlated with BDNF (P< 0.05), and positively correlated with GFAP (P< 0.05). The level of serum GAS5 in the abnormal craniocerebral ultrasound group was higher than that in the normal craniocerebral ultrasound group (P< 0.05). The accuracy of craniocerebral ultrasound combined with serum GAS5 detection in the early diagnosis of neonatal brain injury was 90.12%, the sensitivity was 94.57%, and the specificity was 84.29%, and the accuracy of brain ultrasonography combined with serum GAS5 detection in the diagnosis of severe brain injury was 84.81%.ConclusionSerum GAS5 is up-regulated in neonatal brain injury, and craniocerebral ultrasound combined with serum lncRNA GAS5 level has early diagnostic value for neonatal brain injury.
