ABSTRACT
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 ob-served.Pearson correlation analysis was used to analyze the correlation between NBNA and vascular endothe-lial 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 in-creased 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 re-covery 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.
ABSTRACT
Hypoxic-ischemic encephalopathy (HIE) is a major cause of newborn mortality and childhood disability. Despite hypothermia treatment being the current standard method, it has its limitations and often produces unsatisfactory outcomes. Additionally, due to time and equipment constraints, hypothermia treatment cannot be promptly administered, leading to high mortality rates or varying levels of neurological impairments even after treatment. Hence, the exploration of alternative and effective treatment methods for HIE has become a challenging and highly researched topic in the field of neonatology. Research has shown that HIE induces intricate changes in the neurological system at the physiological, cellular, and molecular levels. Circular RNA (circRNA) exhibits high expression in the central nervous system and plays a role in regulating physiological and pathophysiological processes. Therefore, circRNA holds promise as a potential therapeutic target for HIE. This article provides a comprehensive overview of the regulatory effects of circRNA on different types of neural cells in HIE, aiming to offer new theoretical foundations for the treatment of HIE.

Methods From January 2015 to December 2017, 110 children with HIE were treated in Shijiazhuang No.1 Hospital. Fifty-five children with routine treatment were taken as Western medicine routine treatment group. In addition, 55 children treated with mild hypothermia combined with RHEI were taken as mild hypothermia+RHEI group. Both groups were treated for 14 days and followed up for 10 months. The neonatal behavioral neurological assessment (NBNA) score, mental development index (MDI), psychomotor development index (PDI), myelin basic protein (MBP), S100B protein and neuron specific enolization enzyme (NSE), nerve growth factor (NGF), brain derived neurotrophic factor (BDNF), insulin growth factor-1 (IGF-1), growth hormone (GH), and differences in clinical efficacy in two groups were compared, and the occurrence of adverse reactions was observed. Results The NBNA, MDI, PDI, NGF (μg/L), BDNF (ng/L), IGF-1 (pg/L), and GH (pg/L) of two groups after treatment were higher than those before treatment (the Western medicine routine treatment group: 33.72±3.19 vs. 26.81±2.38, 78.95±5.51 vs. 71.39±4.24, 79.62±4.93 vs. 71.84±4.15, 123.74±22.98 vs. 104.29±15.36, 1 518.35±174.92 vs. 1 197.28±148.43, 38.25±4.96 vs. 23.16±2.87, 39.27±5.24 vs. 20.97±3.15; the mild hypothermia+RHEI group: 39.82±3.36 vs. 26.78±2.53, 84.13±6.29 vs. 71.34±4.27, 85.26±5.74 vs. 71.88±4.13, 145.28±27.52 vs. 104.72±15.41, 1 925.71±204.37 vs. 1 192.61±150.26, 57.94±6.62 vs. 23.13±2.91, 56.43±7.14 vs. 20.94±3.17), NSE (μg/L), MBP (μg/L) and S100B (μg/L) were lower than those before treatment (the Western medicine routine treatment group: 17.05±2.26 vs. 24.96±2.83, 9.71±1.85 vs. 23.14±3.37, 0.93±0.12 vs. 1.49±0.24; the mild hypothermia+RHEI group:12.48±1.94 vs. 25.03±2.81, 5.48±1.42 vs. 23.17±3.35, 0.61±0.07 vs. 1.51±0.25).

ABSTRACT
Objective To explore the clinical value of ganglioside combined with breviscapine in the treatment of neonatal hypoxic ischemic encephalopathy (HIE). Methods Eighty-six children with HIE admitted to our hospital were randomly divided into two groups, the experimental group and the control group, each with 43 cases. The control group was treated with ganglioside, and the experimental group was given ganglioside combined with breviscapine. The therapeutic effects of the two groups, neonatal behavioral neurological assessment (NBNA), serum creatine kinase-BB (CK-BB), cardiac troponin (cTnI), and incidence of sequelae were compared. Results The total effective rate of the experimental group was higher than that of the control group (P<0.05). The improvement of NBNA score, serum CK-BB and cTnI levels in the experimental group were better than those in the control group (P<0.05). After six months of followup, the incidence of sequelae in the experimental group was significantly lower than that in the control group (P<0.05).Conclusion The application of ganglioside combined with breviscapine injection in the treatment of neonatal hypoxic ischemic encephalopathy is effective, which is helpful for promoting the recovery of neurological function and improving serum CK-BB and cTnI levels, and can effectively reduce related sequelae.
ABSTRACT
Neonatal hypoxic-ischemic encephalopathy (HIE) can result in serious outcomes including death during the newborn period and later neuropsychological handicaps.So far,there have been no obvious effect on the improvement of prognosis with traditional treatments,and the cryogenic treatment is the most effective treatment for the past decade,while the clinical application is limited by age and disease course.At present,stem cell transplantation in the treatment of HIE is the new direction,of which the mesenchymal stem cells are outstanding by its easy materials,low immunogenicity and potential nerve regeneration properties.This paper reviews and updates the progress of mesenchymal stem cell transplantation for neonatal HIE.
ABSTRACT
PURPOSE: To investigate the relationship between brain injury patterns on magnetic resonance imaging (MRI) and neurodevelopmental outcomes in neonates with postasphyxial hypoxic ischemic encephalopathy (HIE). METHODS: Clinical characteristics and brain MRI findings of 49 term neonates with postasphyxial HIE were retrospectively reviewed. Brain injury patterns in MRI were classified into five categories, along with evaluation of the posterior limb of internal capsule (PLIC). Neurodevelopmental outcomes were assessed by neurological examination combined with the Bayley Scales of Infant Development II between 1 and 2 years of age. RESULTS: Twenty-three neonates (46.9%) showed abnormal brain MRI finding associated with poor neurodevelopmental outcomes (odds ratio 9.7, 95% confidence interval 1.4, 67.4, P=0.022). The following injury patterns were seen in MRI: abnormality in the basal ganglia-thalamus (BGT) in 4 neonates (17.4%), watershed predominant (WP) pattern in 5 (21.7%), extensive global injury (EGI) in 3 (13.0%), lesions restricted to periventricular white matter (LPWM) in 4 (17.4%), and perinatal arterial ischemic stroke (PAIS) in 2 (8.7%). Additionally, 6 neonate (26.1%) showed lesion in the PLIC. Neonate with BGT and EGI injury patterns showed worse neurodevelopmental outcomes than those with WP and LPWM patterns (P<0.05). Neonate with PLIC lesion also showed poor outcomes (100%). CONCLUSION: Abnormal brain MRI findings in neonates with postasphyxial HIE were associated with the poor neurodevelopmental outcomes. BGT, EGI and PLIC patterns of injury are expected to have worse outcomes than white matter predominant injury patterns such as those in the WP and LPWM.

ABSTRACT
Objective To simulate the process of hypoxic?ischemic brain injury at high altitude in a simulated cabin with plateau low pressure environment, and to prepare a rat model of cerebral injuries at different high altitudes. Method Thirty?two 0?day?old neonatal SD rats were divided into four groups, namely group A ( control group) and three test groups:group B (2000 m group), group C (4000 m group), and group D (6000 m group). The rats of control group were reared in a barrier environment. The rats of test groups were placed in a simulated cabin with plateau low pressure environment, and to prepare neonatal cerebral ischemia?hypoxia model by sport activities. The sport movements were carried out in the cabin in a swimming groove 60 min/d, and not less than 20 hours a day at high altitude low pressure environment. Zea Longa 5 point scale standard was used to determine the behavioral scores at the 3 th 7 th 11 th 15 th days, and samples were collected on the 15th day to observe red blood cell morphology using HE and 2, 3, 5?triphenyltetrazolium chloride ( TTC ) staining and ultrastructure by scanning electron microscopy. Result ( 1 ) The neurological scores of the test groups A, B, C were significantly different from that of the control group (P<0?05), and the scores of test group D and control group were very significantly different ( P <0?01 ) . ( 2 ) The histopathological examination using HE staining showed inflammatory cell infiltration in all rats of the test groups, and the extent of inflammatory cell infiltration was positively correlated with the increase of altitude. ( 3 ) The histopathology with TTC staining revealed prominent ischemia in the cerebral cortex of rats in the plateau hypoxic environment. ( 4 ) Scanning electron microscopy showed that the rat erythrocytes were cap?like in the group B, irregular in the group C, and zigzag shape in the group D. Conclusions In this study, a rat model of neonatal hypoxic?ischemic encephalopathy ( HIE) is successfully established by hypoxic cabin combined with sport activity. This model is stable, reliable, more closely mimicking the pathogenesis and clinical manifestation of neonatal HIE than models prepared with other methods, therefore, may be used in related research.
ABSTRACT
OBJECTIVE:To investigate the clinical efficacy and safety of amoxicillin sodium and clavulanate potassium com-bined with cranial mild-moderate hypothermia in the treatment of neonatal hypoxic-ischemic encephalopathy (HIE) complicating with pulmonary infection. METHODS:80 children with HIE complicating with pulmonary infection were randomly divided into ob-servation group(42 cases)and control group(38 cases). Control group received routine treatment under normal body temperature as lowering intracranial pressure,correcting acid-base balance,giving nutritional support and anticonvulsive treatment,and then was given amoxicillin sodium and clavulanate potassium 30 mg/kg intravenously,tid,more than 30 min each time,for consecutive 3 d. On the basis of control group,observation group was additionally given cranial mild-moderate hypothermia therapy:wearing cooling cap,at 10 ℃;keeping pharynx nasalis temperature at 34 ℃;keeping rectal temperature at 33-37 ℃;decreasing at rate of 1 ℃/h. They continued treatment for 3 d till body temperature decreased to 34.5 ℃;and then cooling cap was taken off to recover normal body temperature. Therapeutic efficacy of HIE and pulmonary infection were observed in 2 groups. NBNA score of 2 groups were recorded 1st,2nd and 4th week after birth,and the occurrence of ADR was observed.
