左卡尼汀联合胞二磷胆碱对新生儿缺氧缺血性脑病的疗效及血清NO、ET-1的影响

Effect of L-carnitine combined with citicoline on the therapeutic effect of neonatal hypoxic-ischemic encephalopathy and serum NO and ET-1

目的 探讨左卡尼汀联合胞二磷胆碱对新生儿缺氧缺血性脑病(NHIE)的疗效及血清一氧化氮(NO)、内皮素-1(ET-1)的影响。方法 选取2020年4月至2023年1月该院收治的95例NHIE患儿,采用随机数字表法将其分为观察组(47例)和对照组(48例)。对照组给予胞二磷胆碱治疗,观察组给予胞二磷胆碱联合左卡尼汀治疗。治疗14 d后评估患儿疗效,统计患儿原始反射、肌张力及意识的恢复时间。检测患儿治疗前、治疗14 d后的氧化应激指标[丙二醛(MDA)、超氧化物歧化酶(SOD)]及血管内皮功能指标(NO、ET-1)水平,采用新生儿神经行为评分(NBNA)评估患儿神经功能水平,并观察治疗方案的安全性,采用Pearson相关性分析NBNA与血管内皮功能指标的相关性。结果 观察组治疗总有效率为91.49%,高于对照组的72.92%(P<0.05);观察组原始反射恢复时间、肌张力恢复时间及意识恢复时间较对照组均缩短(P<0.05);治疗前两组NBNA得分差异无统计学意义(t=1.225,P=0.224),治疗后观察组NBNA得分高于对照组(t=6.223,P<0.001);治疗后,两组MDA水平降低,SOD水平升高(P<0.05),观察组治疗后MDA水平低于对照组,SOD水平高于对照组(P<0.05);治疗后,两组NO、ET-1水平均降低(P<0.05),观察组治疗后NO、ET-1水平低于对照组(P<0.05);观察组、对照组药物不良反应率分别为17.02%、8.33%,两组比较差异无统计学意义(P>0.05);Pearson相关性分析显示,NHIE患儿血清NO、ET-1与NBNA得分均呈负相关(r=-0.546、-0.608,P<0.05)。结论 左卡尼汀联合胞二磷胆碱能够提高NHIE的疗效,缩短临床表现恢复时间,改善神经功能、氧化应激反应、血管内皮功能,不会增加药物不良反应,且血管内皮功能指标与NBNA得分均呈负相关,可作为判断NHIE病情的辅助参考指标。

Objective To explore the effects of L-carnitine combined with citicoline on the therapeutic effect of neonatal hypoxic-ischemic encephalopathy(NHIE)and serum nitric oxide(NO)and endothelin-1(ET-1).Methods A total of 95 children with HIE admitted to the hospital from April 2020 to January 2023 were selected and were divided into observation group(47 cases)and control group(48 cases)by random number table method.The control group was given citicoline,and the observation group was given citicoline combined with L-carnitine.The therapeutic effect was evaluated on 14 days after treatment,and the recovery time of original reflex,muscle tone and consciousness was calculated.The levels of oxidative stress indexes[malondialdehyde(MDA),superoxide dismutase(SOD)]and vascular endothelial function indexes(NO,ET-1)were detected before treatment and 14 days after treatment.Neonatal neurobehavioral score(NBNA)was used to evaluate the neurological function of the children,and the safety of the treatment regimen was observed.Pearson correlation analysis was used to analyze the correlation between NBNA and vascular endothelial function indexes.Results The total effective rate in the observation group was 91.49%,which was higher than 72.92%in the control group(P<0.05).The original reflex recovery time,muscle tone recovery time and consciousness recovery time of NHIE children in the observation group were shorter than those in the control group(P<0.05).There was no significant difference in NBNA scores between the two groups before treatment(t=1.225,P=0.224).After treatment,the NBNA score in the observation group was higher than that in the control group(t=6.223,P<0.001).After treatment,MDA level decreased and SOD level increased in two groups(P<0.05).After treatment,the level of MDA in the observation group was lower than that in the control group,while the level of SOD was higher than that in the control group(P<0.05).After treatment,the levels of NO and ET-1 were decreased in both groups(P<0.05).The levels of NO and ET-1 in the observation group were lower than those in the control group after treatment(P<0.05).The adverse drug reaction rates in observation group and control group were 17.02%and 8.33%,respectively,and there was no significant difference between two groups(P>0.05).Pearson correlation analysis showed that serum NO,ET-1 and NBNA score in NHIE children were negatively correlated(r=-0.546,-0.608,P<0.05).Conclusion L-carnitine combined with citicoline could improve the therapeutic effect of NHIE,shorten the recovery time of clinical manifestations,and improve nerve function,oxidative stress and vascular endothelial function without increasing drugs and adverse reactions.In addition,vascular endothelial function indexes are negatively correlated with NBNA score,which could be used as auxiliary reference indexes for judging NHIE.
