This paper introduces a real-world cohort research model for community-acquired pneumonia （CAP） based on the Jiangsu Traditional Chinese Medicine （TCM） Dominant Diseases Diagnosis and Treatment Data Platform. Firstly， data cleaning is performed by standardizing diagnosis， symptoms， treatment and imaging， intelligently extracting unstructured information， and cleaning and constructing a standardized database. Secondly， for cohort establishment， CAP patients across the province are screened in accordance with CAP diagnostic criteria to build a high-quality disease-specific cohort. Lastly， in terms of protocol design， the characteristics of TCM research and the CAP disease profile are considered to determine appropriate inclusion and exclusion criteria， estimate sample size， define interventions， outcomes and economic evaluations， providing a reference for real-world TCM research on CAP.

Objective To study the changes of lipid peroxidation and antioxidant capacity in patients with hypercholesterolemia.Methods A total of 100 patients with elevated cholesterol treated in the People's Hospital of Qitaihe from January to May 2024 were included in hypercholesterolemia group,and another 80 people with normal blood lipid in the hospital during the same period were included in control group.Malondialdehyde(MDA),glutathione(GSH),glutathione reductase(GR)and total antioxidant capacity(TAC)were determined in all subjects.Results The levels of total cholesterol,low density lipoprotein-cholesterol and MDA in hypercholesterolemia group were significantly higher than those in control group,while the levels of GSH,GR and TAC were significantly lower than those in control group(P＜0.05).Conclusion Patients with hypercholesterolemia have severe lipid peroxidation,which may cause vascular endothelial cell damage.

Objective To explore the effectiveness of the OKR method in improving the efficiency of the whole process of critical value management,and to provide new ideas for the implementation of medical quality improvement in other medical insti-tutions.Methods A hospital in Tianjin was selected as the study object,which used the OKR method to reform the management of critical value since January 2024.The core goal of"improving the effectiveness of critical value management"was set,and the goal was broken down into quantitative key results such as"the rate of receiving the critical value system is over 95％"and"the rate of completing the standardised writing of medical records is up to 85％".Results After the reform,several quantitative key results,such as the completion rate of critical care medical record writing,the rate of standardised medical record writing,and the rate of overtime acceptance,were all better than before.Conclusion Through the OKR method to unify the whole hospital's strategic objectives,and the dynamic adjustment of the program based on data review,the hospital's critical value management efficiency has been significantly improved,effectively guaranteeing the safety of patients,and providing new perspectives and methods for the management of critical value in other medical institutions.

Objective To investigate the relationship between asprosin(Asp)and angiopoietin-like protein 3(ANGPTL3)levels and Diabetic Peripheral Vascular diseases in type 2diabetes mellitus Disease,DPVD)to evaluate their predictive value for DPVD.Methods A total of 141 patients with type 2diabetes who met the inclusion criteria were included and divided into non-DPVD group(n=71)and DPVD group(n=70),and healthy subjects in the same period were selected as normal control group(n=37).General data and expression levels of Asp and ANGPTL3 in the three groups were compared.Spearman correlation analysis was used to explore the correlation between Asp and ANGPTL3 levels and clinical indicators,and Logistic regression was used to analyze the influencing factors of DPVD.The predictive value of serum Asp and ANGPTL3 levels to DPVD was analyzed by receiver operating characteristic curve(ROC).Results Compared with non-DPVD group,the levels of asprosin and angiopoietin-like protein 3 in DPVD group were higher(all P＜0.05).Spearman correlation analysis showed that Asp level was positively correlated with age,SBP,FBG,LDL-C and ANGPTL3(all P＜0.05).ANGPTL3 level was positively correlated with age,SBP,DBP,FBG,TC,TG,LDL-C and Asp(all P＜0.05).Age,course of disease,HbA1c,TG,LDL-C,FCP,Asp and ANGPTL3 were the influencing factors of DPVD(all P＜0.05),while course of disease,TG,Asp and ANGPTL3 were the independent influencing factors of DPVD(all P＜0.05).ROC curve results showed that Asp and ANGPTL3 levels alone predicted DPVD AUC of 0.679 and 0.706,corresponding sensitivity of 88.7％and 78.9％,specificity of 47.1％and 55.7％,respectively.The combined prediction of Asp and ANGPTL3 levels for DPVD was 0.777 AUC,80.3％sensitivity and 64.3％specificity.Conclusion Asp and ANGPTL3have certain predictive value for DPVD,and their combined predictive value is higher.

OBJECTIVE To evaluate the economic burden of the intensive care unit(ICU)patients due to hospital-associated multidrug-resistant organisms(MDROs)infections based on propensity score matching(PSM)so as to provide evidence-based bases for prevention and control of hospital-associated MDROs infection and improvement of utilization efficiency of medical resources.METHODS A total of 2118 patients who were hospitalized in Zibo Central Hospital from Jan.1,2023 to Dec.31,2024 and conformed to the inclusion and exclusion criteria were re-cruited as the research subjects.The patients with hospital-associated MDROs infections were matched in a 1∶1 ratio by PSM(with the clamp value 0.02).Totally 309 pairs were successfully matched.The length of hospital stay and the costs were observed and compared between the MDROs group and the non-MDROs group.RESULTS The MDROs group was with the length of hospital stay 14.00 days longer than the non-MDROs group after the matching(Z=-5.750,P＜0.001),with the total cost of hospitalization increased by 91,420.84 yuan(Z=-8.271,P＜0.001).With the respect to the medical treatment expenses,the expenses of the MDROs group were higher than those of the non-MDROs group,covering the cost of medical service,therapeutic procedures,nursing,western medicine and TCM,and there were significant differences(P＜0.05).Among the differences in the costs between the two groups,the difference in the cost of western medicine was the most signif-icant(22,182.91 yuan),followed by the cost of clinical laboratory test for diagnosis(19,529.60 yuan)and the cost of therapeutic procedures(16,333.50 yuan).CONCLUSIONS The hospital-associated MDROs infections may lead to the extension of hospital stay length of the ICU patients,which then increases the economic burden.There-fore,it is necessary to strengthen the multidisciplinary collaboration and formulate corresponding measures so as to reduce the risk of such infections among the ICU patients.

Objective:To analyze research trends, hotspots, and international collaboration in temporomandibular disorders (TMD) from 2010 to 2024 using bibliometric methods.Methods:A total of 4 368 articles published between January 2010 to December 2024 were retrieved from PubMed using the search strategy temporomandibular disorders[MeSH Terms] OR temporomandibular joint disorders[Title/Abstract]. The R package"bibliometrix" was employed to analyze publication statistics, author collaboration networks, and keyword co-occurrence.Results:The annual publication volume in the TMD field increased 3.4-fold from 2010 to 2024, with an average annual output of 291.2 articles. MANFREDINI DANIELE was identified as the most prolific author (74 articles). The Journal of Oral Rehabilitation ranked first in terms of publication quantity (454 articles). The University of S?o Paulo (Brazil) emerged as the leading contributor, followed by Sichuan University (China) globally. Research hotspots predominantly focused on the DC/TMD diagnostic criteria and pain mechanisms. Analysis of international collaboration networks revealed that core authors (e.g., Lobbezoo F, Manfredini D) have driven advancements in the field through multidisciplinary collaboration (dentistry+psychology+medical imaging). The high-frequency occurrence of the imaging keyword "magnetic resonance imaging (MRI)" underscores its pivotal role in diagnosing disc displacement. Chinese institutions (Sichuan University, Peking University) ranked second globally in research output; however, interdisciplinary international collaboration remained limited, with multiple-country publications (MCP) accounting for only 13.0%. Conclusions:TMD research demonstrates interdisciplinary integration, highlighting the need for future emphasis on Asian population studies and innovative diagnostic/therapeutic technologies.

BACKGROUND:When exercising in a cold environment,the body's inflammatory response is affected by both low temperature and exercise intervention,and its impact and mechanism remain to be explored.OBJECTIVE:To explore the effects and mechanisms of cold water swimming on inflammatory response of rats based on transcriptome sequencing technology.METHODS:40 male SD rats were randomly divided into room temperature control group,room temperature swimming group,cold water control group,and cold water swimming group,with 10 rats in each group.The room temperature control group had no intervention and was free to eat.The room temperature swimming group received swimming at 30 min/time,6 times/week,for 5 weeks;the water temperature was(28±2)℃,and the water depth was 35 cm.In the cold water control group,the rats were placed in a water tank with a depth of 3 cm;the water temperature was(18±2)℃,and they were free to move.The cold water swimming group received swimming at 30 min/time,6 times/week,for 5 weeks;the water temperature was(18±2)℃,and the water depth was 35 cm.Enzyme-linked immunosorbent assay was used to detect the levels of serum interleukin-6,tumor necrosis factor-α,and high-sensitivity C-reactive protein.Based on the transcriptome sequencing results,differentially expressed genes were screened to draw Venn diagrams and heat maps,and Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analysis were performed.The protein-protein interaction network was used to screen core genes.RT-qPCR was used to detect the mRNA expression of IRF7,OAS2,and OASL in rat spleen tissue.RESULTS AND CONCLUSION:(1)The ELISA results showed that compared with the room temperature control group,the levels of various inflammatory indicators in the room temperature swimming group and the cold water swimming group were significantly increased(P＜0.05),and there was no significant difference in the cold water control group.Compared with the room temperature swimming group,there was no significant difference in the expression of inflammatory indicators in the cold water swimming group.Compared with the cold water control group,the expressions of interleukin-6 and tumor necrosis factor-α in the cold water swimming group showed an upward trend,and high-sensitivity C-reactive protein increased significantly(P＜0.05).(2)Transcriptome analysis:Venn diagram showed that there were 39 differentially expressed genes affected by the dual factors of temperature and exercise intervention.Cluster heat map analysis results showed that the overall gene expression trends of the room temperature swimming group and the cold water swimming group were similar,and the cold water control group showed an opposite trend.Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analysis results showed that differentially expressed genes were enriched in the immune system,locomotion,nucleic acid-binding transcription factor activity,NOD-like receptor signaling pathways and other pathways.The number of genes enriched in the NOD-like receptor signaling pathway was relatively large,and the q value was small,which may be a key pathway.The protein-protein interaction network screened out IRF7,OAS2,OASL,IFIT2,IFIT3 and other core genes.(3)RT-qPCR verification results showed that compared with the room temperature control group,the expressions of IRF7,OAS2 and OASL were significantly increased in the room temperature swimming group and the cold water swimming group(P＜0.01),and there was no significant difference in the cold water control group.Compared with the cold water control group,the expression of each gene was significantly increased in the cold water swimming group(P＜0.01).(4)It is concluded that cold water swimming can promote inflammatory response,and its mechanism may be regulated through the NOD-like receptor signaling pathway.

Objective To discuss the accuracy and effectiveness of digital subtraction angiography(DSA)in determining the cause of limb ischemia after extra corporeal membrane oxygenation(ECMO.Methods The clinical data of 3 child patients,who developed 4 times of acute limb ischemia during perioperative period of ECMO at the Affiliated Children's Hospital of Zhengzhou University of China from July to October of 2023,were retrospectively analyzed.In all the child patients,emergency angiography was carried out to quickly identify the cause,then,appropriate treatment plan was adopted to open the blood vessels of the right lower limb.Results After the child patients entered the operating room and received DSA examination,the causes of the limb ischemia were quickly identified.After treatment,the blood supply to the lower limbs was restored.Except for one child who experienced irreversible necrosis of the distal limb due to repeated ischemia-reperfusion injury and required amputation,the other two child patients recovered well.Conclusion It is of great significance to perform DSA examination as soon as possible when the child patients develop limb ischemic manifestations after ECMO so as to quickly identify the cause,promptly restore blood supply to ischemic limbs and increase limb preservation rate,besides,DSA examination can also be used as a preventive measure for child patients after ECMO.
