Objective To investigate the incidence and adverse prognosis of late onset sepsis(LOS)in neonates in neonatal intensive care unit(NICU).Methods A retrospective study was conducted to collect and analyze the peri-natal condition,underlying diseases,invasive procedures,and adverse prognosis of neonates in NICU of a regional maternal and child healthcare hospital from 2019 to 2023.According to whether LOS occurred during hospitaliza-tion,neonates were divided into LOS group and non-LOS group.The LOS group was divided into 5 subgroups based on whether invasive procedures were performed:LOS plus umbilical vein catheter(UVC)group,LOS plus peripherally inserted central catheter(PICC)group,LOS plus sequential catheter group,LOS plus tracheal intuba-tion group,and LOS plus lumbar puncture group,the relationship between LOS and adverse prognosis was ana-lyzed.Results Among 2 945 neonates in NICU,354(12.02％)developed LOS.Comparison between LOS groups and non-LOS group were as follows:in term of perinatal condition of neonates,there were statistically significant difference in weight,gestational age,and whether they were twins between the two groups(all P＜0.001);in term of underlying diseases,there were statistically significant differences in the number of cases of maternal gestational hypertension,neonatal asphyxia,neonatal congenital heart disease,neonatal ventricular dilation,neonatal pneumo-nia,neonatal hyperthyrotropinemia,and neonatal anemia,as well as five invasive procedures between the two groups(all P＜0.05).Compared with the non-LOS group,the incidences of retinopathy of prematurity(ROP),neonatal necrotizing enterocolitis(NNEC),bronchopulmonary dysplasia(BPD),and neonatal respiratory distress syndrome(NRDS)in LOS group were all higher(all P＜0.001).Regression analysis showed that compared with the non-LOS groups,the risk of ROP increased in the LOS group and its subgroups,with the LOS plus sequential catheter group having a 2.27-fold higher risk of ROP than non-LOS group;the risk of NNEC increased in the LOS group and its subgroups,with the LOS plus UVC group having an 8.29-fold higher risk of NNEC than the non-LOS group.Except for the LOS plus UVC group,the risk of BPD increased in the LOS group and other subgroups,with the LOS plus PICC group and LOS plus sequential catheter group having 4.68-and 4.64-fold higher risk of BPD than the non-LOS group,respectively;the risk of NRDS in the LOS plus PICC group was 6.84-fold higher than the non-LOS group(all P＜0.05).The top three pathogens causing LOS were coagulase negative Staphylococcus,Klebsiella pneumoniae,and Escherichia coli.Conclusion LOS can significantly increase the risks of ROP,NNEC,BPD,and NRDS.LOS plus invasive procedures can further increase the risk of adverse prognosis.

Objective To provide relevant suggestions for ethical considerations in clinical research by searching literature related to ethics in clinical research using the visualization analysis software CiteSpace,and to analyze and compare the current research status of clinical research ethics at home and abroad.Methods The papers on the application of medical ethics in clinical trials from the core collection of CNKI and Web of Science databases were collected and the bibliometric software CiteSpace was used to draw a knowledge map of domestic and foreign literature.The research hotspots and development trends of medical ethics in clinical trials were analyzed.Results In terms of the process of informed consent,risk minimization,fair selection,and protection on the rights and interests of vulnerable groups,the focus of medical ethics research in China were basically consistent with foreign literature.The difference was that foreign research focused more on ethical education,the quality of life of research participants,and ethical counseling.Otherwise,domestic research focused more on the quality management of clinical trials and the specificity of traditional Chinese medicine research,with research on vulnerable groups mostly focused on children.Conclusion Chinese researchers should strengthen multi-dimensional research on medical ethics in China,and gradually expand their view from ethical review points and management research to applied research solved clinical problems and the specificity of research participants,and increasing the number and dimensions of research.

OBJECTIVE: To observe the clinical efficacy of acupuncture on mild cognitive impairment (MCI) and its effect on gut microbiota. METHODS: A total of 62 MCI patients were randomly divided into an experimental group (31 cases, 2 cases dropped out) and a control group (31 cases). Both groups received exercise and cognitive training. In addition, the experimental group underwent acupuncture treatment at acupoints including Baihui (GV20), Sishencong (EX-HN1), and bilateral Fengchi (GB20), Xuanzhong (GB39), Zusanli (ST36), Yanglao (SI6), Xinshu (BL15), and etc., once every other day, three times per week, for a total of 12 weeks. Before and after treatment, the Montreal cognitive assessment (MoCA) and mini-mental state examination (MMSE) scores were evaluated in the two groups, changes in gut microbiota were detected using 16S rDNA sequencing technology. The clinical efficacy was assessed after treatment. RESULTS: Compared before treatment, MoCA and MMSE scores were increased in both groups after treatment (P<0.001), with higher scores in the experimental group than those in the control group (P<0.001, P<0.05). After treatment, the relative abundance of Faecalibacterium, Clostridia, and Ruminococcaceae was increased in the experimental group compared with that before treatment (P<0.05). Moreover, the relative abundance of Faecalibacterium in the experimental group was higher than that in the control group (P<0.05). The total effective rate was 82.8% (24/29) in the experimental group, which was higher than 61.3% (19/31) in the control group (P<0.05). CONCLUSION Acupuncture could improve cognitive dysfunction in patients with MCI, and its mechanism may be related to increasing the relative abundance of butyrate-producing bacteria such as Faecalibacterium, Clostridia, and Ruminococcaceae, maintaining the intestinal barrier, and inhibiting related inflammatory responses.
