Objective To summarize the experience of multi-disciplinary team(MDT)in the pediatric department of Qujing Maternal and Child Health Hospital,and to evaluate the effectiveness of MDT on neonatal brain injury.Methods The clinical data of children with brain injury and treated in the pediatrics department of Qujing Maternal and Child Health Hospital from November 2019 to April 2023 were collected.The children with brain injury and treated from October 2019 to June 2020 were regarded as the non-MDT group,and the children with brain injury and treated from July 2020 to April 2023 were regarded as the MDT group for comparative analysis.Chi-square test/t-test was used to compare and analyze the clinical data of the two groups.Results Among the 890 cases of pediatric brain injury,there were 519 males and 371 females.The median and quartiles of the age distribution for the two groups were as follows:MDT group 2.00(0.82,5.00)years and non-MDT group 1.00(1.00,4.00)years.Craniocerebral injury was the main type of brain injury in both groups,in addition,among children with craniocerebral injury and intracranial hemorrhage,the cure rate of MDT group was higher than that of non-MDT group,and the difference was statistically significant(P<0.05).Among the 405 children in MDT group,154(38.0%)underwent the surgery,while among the 485 children in non-MDT group,121(24.9%)underwent the surgery.The difference was statistically significant(P<0.05).23.2% of children in MDT group were in critical condition during the hospitalization,which was significantly lower than that in non-MDT group(30.5%),and the difference was statistically significant(P<0.05).The unhealed rate of MDT group(2.0%)was also significantly lower than that of non-MDT group(5.6%),the cure rate of MDT group(40.5%)was significantly higher than that of non-MDT group(34.4%),and there was a statistically significant difference(P<0.05).The expense of treatment,medicine and sanitary materials in MDT group were lower than those in non-MDT group,and the differences were statistically significant(P<0.05).The multivariate Logistic regression model analysis of the cure rate of children with brain injury showed that the MDT model could effectively improve the cure rate of children with brain injury(RR = 1.513,95% CI = 1.134-2.020).The results of multiple linear regression model analysis showed that there was no statistical difference in the effect of MDT on the actual hospitalization days of children(P>0.05).Conclusion Using MDT model to diagnose and treat children with brain injury is helpful to improve the cure rate,reduce the risk of children's disease aggravation,and achieve the significant therapeutic effects in children with brain injury.MDT model is worth popularizing and applying in children with brain injury.

Objectives:To finely divide the aortic sinus into sections and accurately localize the coronary ostium through CARTO three-dimensional mapping,and to assess the clinical effects of treating aortic sinus cusps premature ventricular contraction(ASC-PVC)and the ablation risk in the corresponding area with zero X-ray radiofrequency ablation. Methods:A total of 66 patients who underwent radiofrequency ablation for ASC-PVC from January 2020 to January 2023 were included in this analysis,patients were divided into experimental group(n=34)and conventional group(n=32).In the conventional group,the CARTO 3 system was used to create an aortic sinus model through the conventional method.The earliest stimulating target was identified by using electrical stimulation mapping(ESM).Radiofrequency ablation treatment was performed after the distance between the target and the coronary ostium was precisely measured by coronary angiography through the hollow tube of the ablation catheter or coronary angiography tube.In the experimental group,the CARTO 3 system was used to build a model of the aortic sinus and the coronary ostium and aortic sinus were divided into sections.The earliest stimulating target was identified by ESM.After localizing coronary ostium through the impedance changing pattern on the ablation catheter tips,catheter ablation was performed with zero X-ray.The data regarding the impedance of the ablation catheter in the aortic sinus were collected.The total operative time,the operative time in the aortic sinus,contrast dosage,X-ray exposure time,immediate and short-term success rates of the operation and complication rates were compared between the two groups.Besides,the distribution of successfully ablated targets and their relationship with the risk of ablation were analyzed in both groups. Results:There was no significant statistical difference in the immediate and short-term success rates between the two groups(93.8%vs.94.1%;90.6%vs.88.2%,both P>0.05).The experimental group did not receive contrast agents during the operation,and the total operation time and intra-aortic sinus operation time in the experimental group were significantly shorter than those in the conventional group([58.76±4.94]min vs.[66.91±5.94]min,P<0.001;[43.12±4.49]min vs.[50.31±5.18]min,P<0.001).During the process of moving the ablation catheter from the intra-aortic sinus to the coronary artery opening and into the coronary artery,the impedance suddenly increased,which was significantly different from the impedance in other parts of the intra-aortic sinus(all P<0.001). Conclusions:Radiofrequency ablation of ASC-PVC with zero X-ray can simplify the procedures and shorten the operative time.The steep increase in impedance at the tip of the ablation catheter can be used as a basis for localizing the coronary ostium.Dividing the aortic sinus into sections allows a detailed assessment of the risk for ablation treatment at the targets.

Conclusions:The implementation of dyadic intervention on elderly stroke patients and caregivers can make their discharge preparation process more adequate, thus reducing the caregiver′s care pressure, reducing the unplanned readmission rate of patients, and improving their health outcomes.

L-theanine has been shown to have a therapeutic effect on depression.However,whether L-theanine has an excellent preventive effect on depression in children and adolescents and what its mechanism is have not been well explained.Given the complexity of the pathogenesis of depression,this study investigated the preventive effect and mechanism of L-theanine on depression in juvenile rats by combining serum and hippocampal metabolomic strategies.Behavioral tests,hippocampal tissue sections,and serum and hippocampal biochemical indexes were studied,and the results confirmed the preventive effect of L-theanine.Untargeted reversed-phase liquid chromatography-quadrupole-time-of-flight mass spec-trometry and targeted hydrophilic interaction liquid chromatography-triple quadrupole mass spec-trometry were developed to analyze the metabolism changes in the serum and hippocampus to screen for potential biomarkers related to L-theanine treatment.The results suggested that 28 abnormal me-tabolites in the serum and hippocampus that were considered as potential biomarkers returned to near-normal levels after L-theanine administration.These biomarkers were involved in various metabolic pathways,mainly including amino acid metabolism and lipid metabolism.The levels of amino acids and neurotransmitters in the phenylalanine,tryptophan,and glutamic acid pathways were significantly reduced after L-theanine administration compared with chronic unpredictable mild stress-induced rats.In summary,L-theanine had a significant preventive effect on depression and achieved its preventive results on depression by regulating various aspects of the body,such as amino acids,lipids,and inflammation.This research systematically analyzed the mechanism of L-theanine in preventing depression and laid the foundation for applying L-theanine to prevent depression in children and adolescents.

Viscum coloratum (Kom.) Nakai is a well-known medicinal plant. However, the optimal harvest time for V. coloratum is unknown. Few studies were performed to analyze compound variation during storage and to improve post-harvest quality control. Our study aimed to comprehensively evaluate the quality of V. coloratum in different growth stages, and determine the dynamic variation of metabolites. Ultra-performance liquid chromatography tandem mass spectrometry was used to quantify 29 compounds in V. coloratum harvested in six growth periods, and the associated biosynthetic pathways were explored. The accumulation of different types of compounds were analyzed based on their synthesis pathways. Grey relational analysis was used to evaluate the quality of V. coloratum across different months. The compound variation during storage was analyzed by a high-temperature high-humidity accelerated test. The results showed that the quality of V. coloratum was the hightest in March, followed by November, and became the lowest in July. During storage, compounds in downstream steps of the biosynthesis pathway were first degraded to produce the upstream compounds and some low-molecular-weight organic acids, leading to an increase followed by a decrease in the content of some compounds, and resulted in a large gap during the degradation time course among different compounds. Due to the rapid rate and large degree of degradation, five compounds were tentatively designated as "early warning components" for quality control. This report provides reference for better understanding the biosynthesis and degradation of metabolites in V. coloratum and lays a theoretical foundation for rational application of V. coloratum and better quality control of V. coloratum during storage.

Antipsychotic medications are commonly used to treat schizophrenia,but they can have negative effects on lipid metabolism,leading to an increased risk of cardiovascular diseases,reduced life expectancy,and difficulties with treatment adherence.The specific mechanisms by which antipsychotics disrupt lipid metabolism are not well understood.Sterol regulatory element-binding proteins(SREBPs)are important transcriptional factors that regulate lipid metabolism.Proprotein convertase subtilisin/kexin type 9(PCSK9),a gene regulated by SREBPs,plays a critical role in controlling levels of low-density lipoprotein cholesterol(LDL-C)and has become a focus of research on lipid-lowering drugs.Recent studies have shown that antipsychotic drugs can affect lipid metabolism through the SREBP/PCSK9 pathway.A deep understanding of the mechanism for this pathway in antipsychotic drug-related metabolic abnormalities will promote the prevention of lipid metabolism disorders in patients with schizophrenia and the development and application of new drugs.
