Objective: To investigate the effects of vitamin B2 (VB2) combined with blue light irradiation on the recovery process and liver function of neonatal jaundice. Method: 150 children with jaundice admitted from May 2024 to October 2025 were selected and randomly divided into a control group and an experimental group using a random number table method, with 75 cases in each group. The conventional group received blue light irradiation treatment, while the experimental group received oral VB2 treatment on the basis of the conventional group. Compare the oxidative stress response of two groups of children [glutathione peroxidase (GSH Px) higher than the control group, 8-hydroxydeoxyguanosine (8-OHdG), advanced protein oxidation products (AOPP), superoxide anion (O2-)], liver microcirculation [von Willebrand factor (vWF), soluble thrombomodulin (sTM), hepatic artery resistance index (HA-RI), portal vein blood flow velocity (PVV)], bilirubin excretion [total bilirubin (TBil), indirect bilirubin (IBil)], liver function [alanine aminotransferase (ALT), aspartate aminotransferase (AST)], rehabilitation process [phototherapy time, bilirubin recovery time to normal, jaundice regression time]. Hospitalization rehabilitation time and treatment safety. Result: After treatment, the GSH Px levels in the experimental group were higher than those in the control group, while 8-OHdG, AOPP, and O2- levels were lower than those in the control group (P<0.05); The vWF, sTM, and HA-RI of the experimental group were lower than those of the control group, while PVV was higher than that of the control group (P<0.05). The TBil, IBil, ALT, and AST of the experimental group were (80.52 ± 5.47) μ mol/L, (68.52 ± 5.49) μ mol/L, (30.25 ± 5.48) U/L, and (32.14 ± 5.22) U/L, respectively, which were lower than those of the conventional group [(85.19 ± 6.44) μ mol/L, (74.37 ± 6.52) μ mol/L, (35.29 ± 6.17) U/L, (38.55 ± 6.48) U/L], and the difference was statistically significant (P<0.05). The phototherapy time, bilirubin recovery time, jaundice resolution time, and hospital rehabilitation time of the experimental group were (3.05 ± 0.33) days, (4.22 ± 1.39) days, (5.41 ± 1.27) days, and (5.12 ± 0.49) days, respectively, which were lower than those of the conventional group [(3.68 ± 0.36) days, (5.36 ± 1.45) days, (6.28 ± 1.33) days, and (6.51 ± 0.54) days], and the difference was statistically significant (P<0.05). The incidence of adverse reactions in the experimental group was not significantly different from that in the control group (P>0.05). Conclusion: VB2 combined with blue light irradiation can alleviate oxidative stress response and improve liver microcirculation in children with jaundice. It has a positive effect on promoting bilirubin excretion and improving liver function, and does not significantly increase treatment risk while promoting the recovery of children. It has high safety and can be further promoted.

新生儿期的免疫系统发育阶段对维持新生儿健康至关重要,具有独特的免疫调节机制。近年来,人们越来越关注髓源性抑制细胞（MDSCs）在新生儿免疫调节中的作用。MDSCs是一类免疫抑制功能强大的异质性细胞群体,它们能够通过多种机制调节免疫应答。MDSCs在新生儿中的调节作用对防止过度免疫反应和促进免疫耐受至关重要,有助于预防新生儿期炎症性疾病,并对其后续健康产生积极影响。近期研究文献分析展示了MDSCs在新生儿免疫调节中的多种作用机制,包括在特定病理条件下的保护作用、与新生儿期炎症反应的相互作用,以及对长期免疫发展的潜在影响。因此,深入理解MDSCs在新生儿免疫中的角色,不仅有助于揭示其复杂的调节机制,也为制定新的预防和治疗新生儿炎症性疾病的策略提供了新的思路。

The developmental stage of the immune system during the neonatal period is crucial for maintaining neonatal health,characterized by unique immunoregulatory mechanisms．In recent years,increasing attention has been drawn to the role of myeloid-derived suppressor cells（MDSCs）in neonatal immune regulation．MDSCs represents a heterogeneous population of cells with potent immunosuppressive functions,capable of modulating immune responses through various mechanisms．The regulatory role of MDSCs in neonates is vital for preventing excessive immune reactions and promoting immune tolerance,thereby aiding in the prevention of neonatal inflammatory diseases and positively influencing subsequent health outcomes．Analysis of recent research literature reveals multiple mechanisms through which MDSCs contribute to neonatal immune regulation,including protective effects under specific pathological conditions,interactions with neonatal inflammatory responses,and potential impacts on long-term immune development．Therefore,a comprehensive understanding of the role of MDSCs in neonatal immunity not only helps elucidate their intricate regulatory mechanisms but also provides novel insights for developing strategies for the prevention and treatment of neonatal inflammatory diseases．

目的 研究影响新生儿低血糖的相关危险因素。方法 回顾性分析新生儿科570例新生儿的临床资料,其中新生儿低血糖组190例,正常血糖组新生儿380例,采用Logistic回归分析新生儿低血糖相关危险因素。结果 单因素Logistic回归分析显示,新生儿体质量减轻、早产、新生儿呼吸衰竭、新生儿呼吸窘迫、新生儿感染、母亲分娩年龄增大、经产妇、剖宫产、双胎、妊娠期糖尿病、妊娠期高血压疾病是新生儿低血糖发生的危险因素（均P<0.05）;多因素Logistic回归分析显示,早产（OR=2.115,95%CI：1.186~3.772）、剖宫产（OR=6.92,95%CI：4.202~11.397）是新生儿低血糖发生的危险因素（均P<0.05）。结论 早产、剖宫产是新生儿低血糖发生的危险因素,应根据危险因素及时识别和治疗新生儿低血糖,为新生儿提供及时产后护理指导,以降低新生儿低血糖发生率。

Objective To study the relevant risk factors of neonatal hypoglycemia．Methods A retrospective analysis was conducted on the clinical data of 570 newborns in neonatal pediatrics,including 190 cases in the neonatal hypoglycemia group and 380 cases in the normal blood glucose group．Logistic regression analysis was used to analyze the risk factors related to neonatal hypoglycemia．Results Single factor Logistic regression analysis showed that neonatal weight loss,premature,neonatal respiratory failure,neonatal respiratory distress,neonatal infection,the mother’s age of delivery,multipara,cesarean section,twins,pregnancy diabetes,pregnancy hypertension were the risk factors for neonatal hypoglycemia,all of which had statistical significance（all P<0.05）．In multivariate Logistic regression analysis,premature（OR=2.115,95% CI：1.186-3.772）and cesarean section（OR=6.92,95% CI：4.202-11.397）were risk factors for neonatal hypoglycemia（both P<0.05）．Conclusions Premature and cesarean section are risk factors for the occurrence of neonatal hypoglycemia in the local area．Timely identification and treatment of neonatal hypoglycemia based on risk factors,providing timely postpartum nursing guidance for newborns,can reduce the occurrence of neonatal hypoglycemia．

目的 分析阿莫西林克拉维酸钾与第三代头孢类抗菌药联合应用于新生儿肺炎患儿的应用效果及其对患儿肠道菌群的影响。方法 选择在2021年2月—2022年11月期间于我院新生儿科接受相关治疗的100例新生儿肺炎患儿,依照简单随机化法将患儿分为研究组（n=50）及参照组（n=50）。给予参照组常规新生儿肺炎治疗,在此基础上给予研究组患者阿莫西林克拉维酸钾与第三代头孢类抗菌药的联合治疗。治疗结束后对比两组患儿的血清因子水平、肠道菌落情况、临床疗效以及不良反应发生情况。结果 治疗前,两组患儿的血清因子水平、肠道内菌群数量比较差异无统计学意义（P>0.05）,治疗后两组患儿的降钙素原（procalcitonin,PCT）、C-反应蛋白（C-reactive protein,CRP）、白细胞计数（white blood cell count,WBC）、肠球菌、肠杆菌、双歧杆菌以及乳酸杆菌水平均有改善（P<0.05）,其中研究组的PCT、CRP、WBC、肠球菌、双歧杆菌以及乳酸杆菌数量低于参照组,而研究组的肠杆菌数量高于参照组;同时研究组的临床有效率（94.00%）与参照组的临床有效率（86.00%）比较差异无统计学意义（P>0.05）;两组患儿的不良反应发生率比较差异无统计学意义（P>0.05）,但其中研究组腹泻的发生率高于参照组（P<0.05）。结论 在对新生儿肺炎患儿进行治疗时采取阿莫西林克拉维酸钾单纯治疗与阿莫西林克拉维酸钾+第三代头孢类抗菌药（头孢他啶）的临床疗效相当,联合用药虽能更为显著地减少患儿机体的细菌数量,改善血清因子水平,但更易发生腹泻的并发症,且为了减少耐药性,应适当采用单独用药。

Objective To analyze the application effect of amoxicillin clavulanate potassium combined with third-generation cephalosporin antibiotics in children with neonatal pneumonia and its impact on the intestinal microbiota．Methods From February 2021 to November 2022,100 newborns with pneumonia who received relevant treatment in the Department of Neonatology at the First People’s Hospital of Shangqiu City were randomly divided into a study group（n=50）and a reference group（n=50）using a simple randomization method．Routine treatment was provided for neonatal pneumonia in the reference group,and on this basis,a combination treatment of amoxicillin,clavulanate potassium,and third-generation cephalosporin antibiotics was applied on the study group patients．After treatment,the serum factor levels,intestinal colony status,clinical efficacy,and incidence of adverse reactions were compared between the two groups of children．Results Before treatment,there were no statistically significant differences in serum factor levels and intestinal microbiota between the two groups of children（P>0.05）．After treatment,the levels of procalcitonin（PCT）,C-reactive protein（CRP）,white blood cell count（WBC）,Enterococcus,Enterobacter,Bifidobacterium,and Lactobacillus in the two groups of children improved（P<0.05）,with the levels of PCT,CRP,WBC,the number of Enterococcus,Bifidobacterium,and Lactobacillus in the study group was lower than that in the reference group,while the number of Enterobacter in the study group was higher．There was no statistically significant difference（P>0.05）in the clinical response rate between the study group（94.00%）and the reference group（86.00%）．There was no statistically significant difference in the incidence of adverse reactions between the two groups of children（P>0.05）,but the incidence of diarrhea in the study group was higher than that in the reference group（P<0.05）．Conclusions The clinical efficacy of amoxicillin clavulanate potassium alone and amoxicillin clavulanate potassium+third-generation cephalosporin antibiotics（ceftazidime）in the treatment of newborns with pneumonia is comparable．Although the combination therapy can significantly reduce the number of bacteria in the body of children and improve serum factor levels,it is more prone to complications of diarrhea．In order to reduce drug resistance,separate medication should be appropriately used．
