Objective To analyze the etiological characteristics of pediatric bacterial meningitis(BM)and change of biochemical indicators in cerebrospinal fluid,and establish a diagnostic model for pathogen differentiation based on biochemical indicators in cerebrospinal fluid.Methods Eighty children with BM in the Children's Hospital Affiliated to Zhengzhou University from May 2021 to May 2023 were selected as BM group,and their pathogen distribution as well as cytological and biochemi-cal indicators in cerebrospinal fluid were analyzed.Forty non-central nervous system infections chil-dren with cytological and biochemical testing in cerebrospinal fluid in the same period were included as control group.The relationships between indicators in cerebrospinal fluid and pathogen types in BM children were analyzed,and a diagnostic model was constructed.Results A total of 85 pathogens were detected in 80 BM children,including 48 Gram-negative bacteria(56.47%)and 37 Gram-pos-itive bacteria(43.53%).The BM group showed significantly higher white blood cell count and lym-phocyte percentages,lower neutrophil and monocyte percentages,lower glucose and chloride levels in cerebrospinal fluid,and higher protein levels in cerebrospinal fluid when compared to the control group(P<0.05).Among BM children,those infected with Gram-negative bacteria had significantly higher white blood cell count and lymphocyte percentages,as well as lower glucose and chloride levels in cerebrospinal fluid when compared to those with Gram-positive bacterial infections(P<0.05).Multivariate Logistic analysis revealed that white blood cell count,lymphocyte percentage,glucose,and chloride levels in cerebrospinal fluid were significantly associated with pathogen types(P<0.05).A diagnostic model based on these factors demonstrated an area under the receiver operating characteristic(ROC)curve of 0.925 for distinguishing Gram-positive and Gram-negative infections,with a cutoff value of 0.754,asensitivity of 76.25%,and aspecificity of 98.33%.Conclusion The primary pathogens of pediatric BM include Acinetobacter baumannii,Escherichia coli,Klebsiella pneumoniae,coagulase-negative Staphylococcus,Staphylococcus aureus,and Streptococcus pneumoni-a,accompanied by elevated white blood cell count and lymphocyte percentages as well as reduced glucose and chloride levels in cerebrospinal fluid,which is helpful in differentiating Gram-positive from Gram-negative infections and guiding antibiotic therapy.

To investigate the effectiveness of a self-developed intelligent medical record writing assistant in enhancing the efficiency of discharge record writing and improving the quality of discharge records, and to assess physicians' satisfaction with the assistant. This study was conducted as a prospective cluster-randomized controlled trial. From January 25 to June 25, 2024, clinicians in the coronary heartdisease ward of Fuwai Hospital, Chinese Academy of Medical Sciences were selected as the research object. Using the method of cluster-randomized allocation, the four wards were randomly assigned 1∶1, with physicians and their medical records assigned to the corresponding group based on the ward. The experimental group utilized the intelligent medical record writing assistant, with 46 physicians included and 4105 medical records collected. The control group used traditional writing methods, with 41 physicians included and 4680 medical records collected. Primary outcome measures included quantitative analysis of medical record writing efficiency and medical record writing quality. Secondary outcomes assessed physicians' satisfaction with the use of the intelligent medical record writing assistant. The average writing time for discharge records in the experimental group was significantly shorter than that in the control group(5.73 min The intelligent medical record writing assistant can significantly enhance the writing efficiency and optimize medical record quality concurrently, and physicians are highly satisfied with it. This study validates the effectiveness of the new model of intelligent medical record writing applied to clinical practice, and provides a paradigm for the in-depth application and promotion of this model in the future.

Objective To investigate the effects of electroacupuncture on the intestinal NIMA-related kinase 7(NEK7)/NOD-like receptor thermal protein domain associated protein 3(NLRP3)signaling pathway in mice with Parkinson's disease.Methods According to the randomized number table method,36 C57BL/6 mice were randomly divided into the control group,the model group,and the electroacupuncture group,with 12 mice per group.The Parkinson's disease mouse model was established by gavage of rotenone solution(10 mg/kg)for 28 d.After molding,the electroacupuncture group was stimulated with"Fengfu"(DU17),"Taichong"(LR3),and"Zusanli"(ST36)for 14 d,while the control group and the model group were only treated with immobilization.The motor ability of mice was detected by pole climbing test and hindlimb rating score,the positive expressions of nigral tyrosine hydroxylase(TH)and colon occludin were detected by immunohistochemistry,the histological morphology of colon was observed by hematoxylin-eosin staining,and Western blotting was used to detect the protein expressions of NEK7,NLRP3,Caspase-1,and interleukin-1β(IL-1β).Results Compared with the control group,mice in the model group had lower score on the pole climbing test and a higher hindlimb rating score(P<0.01);the average optical densities of nigral TH and colon occludin were decreased(P<0.01);significant inflammatory infiltration was observed in the colonic tissue,and the muscularis propria was thinned;and the protein expressions of NEK7,NLRP3,Caspase-1,and IL-1β in the colonic tissue were elevated(P<0.01).Compared with the model group,mice in the electroacupuncture group had higher score on the pole climbing test and a lower hindlimb rating score(P<0.01);the average optical densities of nigral TH and colon occludin were increased(P<0.01);the degree of inflammatory infiltration of colonic tissues decreased,and the muscularis propria was thickened;and the protein expressions of NEK7,NLRP3,Caspase-1,and IL-1β of colonic tissues were decreased(P<0.01).Conclusion Electroacupuncture at"Fengfu"(DU17),"Taichong"(LR3),and"Zusanli"(ST36)can improve motor functional impairments in mice with Parkinson's disease,and the mechanism may be through the inhibition of intestinal NEK7/NLRP3 pathway,improving the intestinal barrier damage,relieving the intestinal inflammation,and improving the dopaminergic neuron injury.
