With the widespread use of antimicrobial agents, bacterial drug resistance has become an increasingly severe issue, posing significant challenges to global healthcare. Traditional Chinese medicine (TCM) has emerged as a research focus in the field of bacterial resistance due to its broad sources, high safety profile, low toxicity, and antimicrobial mechanisms distinct from those of chemical drugs. Studies have shown that various TCM herbs, such as Scutellaria baicalensis, exert antibacterial effects through multiple pathways, including disrupting the integrity of bacterial cell walls and membranes, inhibiting nucleic acid and protein synthesis, and impairing energy production and metabolism. Additionally, certain TCM herbs, including Scutellaria baicalensis, Coptis chinensis, and Fritillaria thunbergii, can reverse antimicrobial resistance by eliminating resistant plasmids, inhibiting bacterial efflux pump function, and suppressing β-lactamase activity. TCM holds promising potential for antibacterial applications and synergistically reversing antimicrobial resistance, though systematic analyses remain limited. This review summarizes the mechanisms of antibacterial action of TCM and current research on its synergistic use with antimicrobial agents to reverse drug resistance, aiming to provide insights for developing novel TCM-based antimicrobials and addressing bacterial resistance.

Objective:To investigate the etiological distribution of severe community-acquired pneumonia (CAP) in children in Hebei Province.Methods:The nasopharyngeal swab samples and clinical data from 314 children with severe pneumonia were retrospectively analyzed between January 2014 and January 2016.Results:Among the 314 children, 298 (94.94%) showed positive result for pathogens in their nasopharyngeal swab samples, with 246 cases (78.34%) of multiple pathogens, predominantly mixed viruses and bacteria (206 cases, 65.61%). A total of 848 strains of pathogens were detected, including 483 strains (56.96%) of viruses, predominantly respiratory syncytial virus with 97 strains of subtype A and 86 strains of B. Bacteria and atypical pathogens ( Mycoplasma pneumoniae) had 365 strains (43.04%), mainly Streptococcus pneumoniae (220 strains) and Haemophilus influenzae (119 strains). The detection rate of pathogens was higher in children under one year of age ( χ2=21.389, P<0.001). There were no significant differences in different seasons, but the detection rates of respiratory syncytial virus A, respiratory syncytial virus B, and Streptococcus pneumoniae were higher in autumn, winter, and spring, respectively, with statistically significant differences ( χ2=22.205, P<0.001; χ2=37.874, P<0.001; χ2=11.380, P=0.009). Conclusions:Nasopharyngeal swab sample testing in children with severe pneumonia typically shows a coexistence of viral and bacterial pathogens, with detection rates varying among different age groups and seasons. Nasopharyngeal swab sample testing for pathogens provides valuable references for the identification of clinical pathogens.

Objective To conduct basic research on the structure and function of the heart in cynomolgus monkeys older than 10 years to provide data for animal selection in elderly disease research.Methods A total of 144 cynomolgus monkeys＞10 years old were selected as research subjects,including 37 females and 66 males in the 10～15 years group,and 21 females and 20 males in the 16～20 years group.Basic data on cardiac structure and function in middle-aged and elderly cynomolgus monkeys were obtained through comparative analysis of general indicators(body mass index,blood pressure,and heart rate),blood biochemical indicators(blood glucose,blood lipids,and ion indicators),and cardiac structure and function indicators.Results General indicators for the 10～15 years and 16～20 years groups were compared.As age increased,the blood pressure and heart rate of female and male monkeys increased,and there was a significant difference in blood pressure changes between male monkeys.A comparison of two sets of blood biochemical indicators showed that,as age increased,blood glucose,triglycerides,total cholesterol,low-density lipoprotein cholesterol,blood calcium,blood sodium,and blood potassium increased,while lactate dehydrogenase decreased,in female and male monkeys.Among these,blood glucose,triglycerides(males),total cholesterol,high-density lipoprotein cholesterol(males),low-density lipoprotein cholesterol(males),blood calcium,blood sodium,blood potassium,and lactate dehydrogenase showed significant changes.A comparison of cardiac contractile function between the two groups showed that,as age increased,the anterior and posterior diameters of the left atrium significantly decreased in both female and male monkeys.Female monkeys showed a significant decrease in the interventricular septal end systolic diameter,left ventricular end diastole and systolic diameters,left ventricular end diastolic and systolic volumes,and left ventricular mass index,while no significant changes were seen in male monkeys.A comparison of diastolic function between the two groups showed that,as age increased,the late diastolic velocity of the mitral valve decreased significantly in male monkeys,while the early diastolic velocity of the left ventricular sidewall increased significantly in female monkeys.Correlation analysis was conducted between the metabolic indicators and the cardiac structure and function indicators of female and male monkeys.The correlations between metabolic indicators and cardiac structure and function indicators were weak in female monkeys,for which the maximum absolute Γ value did not exceed 0.39.However,the correlations between metabolic indicators and cardiac structure and function indicators were relatively strong in male monkeys,for which the maximum absolute Γ value reached 0.66.Conclusions Based on ultrasound analysis combined with metabolic indicators,the heart function of cynomolgus monkeys was studied,and basic data related to the structure and function of the heart in middle-aged and elderly cynomolgus monkeys were obtained.As age increased,blood glucose and lipid indicators increased in cynomolgus monkeys,while cardiac systolic and diastolic functions show a downward trend,similar to changes in middle-aged and older adult human populations.These data provide support for animal selection in research on age-related diseases related to heart function.

Public hospitals are important entities in providing medical services in China and main forces in safeguarding people's health.Advancing the quality of medical services in public hospitals and further ensuring the well-being of the public necessitates the enhancement of Party building within public hospitals and the Party's comprehensive leadership over them.Party building guidance is an essential requirement for the development of public hospitals.Concurrently,effective Party building pub-licity is crucial for accelerating Party construction efforts,fostering harmonious doctor-patient relationships,expanding the range of hospital services,and creating a favorable public opinion environment.This paper examines the practices of Party building publicity at Minhang Campus of Guangdong Second Provincial General Hospital,distilling strategies that focus on"highlighting key points,building platforms,and reinforcing links".The strategies provide a reference for the publicity practice of Party build-ing in public hospitals in the new era.

Objective To investigate the impact of preoperative abdominal aortic balloon occlusion and modified uterine vascular occlusion on repeat cesarean delivery in patients with placenta previa and placenta accreta spectrum disorders.Methods A total of 97 patients with placenta previa and placenta accreta spectrum disorders who underwent repeat cesarean section at Hefei Maternal and Child Health Hospital between April 2016 and Decem-ber 2022 were included in this study.Among them,the control group consisted of 48 cases who underwent abdominal aortic balloon occlusion before the operation,while the observation group comprised 49 cases who underwent modified uterine vascular occlusion during the operation.Intraoperative and postoperative complications were observed and compared between the two groups.Results The number of bilateral uterine artery embolization post-operation and the average hospitalization cost in the observation group were significantly lower compared to those in the control group(P<0.05).However,there were no significant differences observed between the two groups regarding average intraoperative blood loss,red blood cell suspension transfusion volume,hysterectomy rate,and bladder rupture rate(P>0.05).Conclusions Both surgical methods effectively reduce intraoperative bleeding in the treatment of repeat cesarean section in patients with placenta previa and placenta accreta spectrum disorders.However,modified uterine vascular occlusion demonstrates no complications related to vascular intervention or X-ray exposure,ensuring high maternal and child safety while significantly reducing hospitalization costs.Therefore,it is highly recommended for clinical promotion.

Objective To analyze differentially expressed microRNAs(DEmiRNAs)in osteoporosis(OP)and chronic obstructive pulmonary disease(COPD)using bioinformatics tools,and to explore the interrelationship between these two diseases.Methods Gene expression microarrays for OP and COPD were retrieved from the GEO database.Differential analysis was conducted using the limma pack-age in R software version 4.1.0,identifying DEmiRNAs between OP and COPD.The selected DEmiRNAs were then subjected to target gene prediction using the miRDB and TargetScan databases.Predicted target genes were analyzed for transcription factor predictions using KOBAS,followed by GO and KEGG pathway analyses.Protein-protein interaction(PPI)network data for the target genes were down-loaded from the STRING database and analyzed and visualized using Cytoscape to construct a PPI network and model.Results Four DEmiRNAs were identified as differentially expressed between OP and COPD microarrays:hsa-miR-631,hsa-miR-940,hsa-miR-508-5p and hsa-miR-1470.PPI network analysis revealed seven core genes:UBA52,UBE2I,UBE2N,STAM,IPO5,CD28 and STX6.Conclusion The interconnection between OP and COPD may be mediated through a series of physiological and pathological responses such as hypoxia,chronic inflammation,oxidative stress,calcium ion reabsorption,and mitochondrial autophagy.Of these,hsa-miR-940 exhibits the closest relationship between the two diseases,suggesting a pivotal role in linking their pathogenesis.

Although immunotherapy has made a breakthrough in the treatment of cancer,the emergence of drug resistance has limited be-nefits in most patients,and reversing immunotherapy resistance remains a hotly debated and unresolved issue.The tumor microenviron-ment(TME)comprises a large number of T lymphocytes.During the biological processes of proliferation,activation,and the effect of tumor-infiltrating lymphocytes(TILs),TILs face severe local metabolic stress,resulting in metabolic reprogramming to meet the markedly increased energy demand and biosynthesis requirements.This process of adaptive changes in the metabolic pattern is closely related to the pheno-type and function of TILs,affecting immunotherapy efficacy and mediating immunotherapy resistance.In recent years,with the study of TIL metabolism and the search for specific metabolic regulatory points,targeting the TIL metabolic pathway could restore the tumor-killing func-tion and reverse immunotherapy resistance.This review explores the relationship between the metabolic reprogramming of TILs and im-mune resistance,and provides a new strategy for reversing immune resistance.

Objective:To investigate the change of chemical exchange saturation transfer (CEST) imaging in the bilateral substantia nigra (SN) and red nucleus (RN) of Parkinson disease (PD), and to explore the value of CEST-MRI for the clinical application of PD.Methods:This was a cross-sectional study. A total of 45 PD patients (PD group) and 21 sex-, age-, and cognitive-function matched normal control subjects (NC group) were retrospectively enrolled from December 2012 to July 2015 in Beijing Hospital. All subjects underwent brain CEST-MRI and routine MRI. Based on the MATLAB software package, the 4-pool Lorentz fitting model was applied to analyze the signal change of CEST imaging, which could acquire the mean amplitudes of the 4-pool parameters including Amide, nuclear overhauser enhancement (NOE), direct water saturation (DS) and magnetization transfer (MT) in the bilateral SN and RN. Independent samples t test and Mann-Whitney U test were used to compare CEST parameters between the PD group and the NC group and controlled by Bonferroni correction. The combined model was constructed based on parameters with inter-group differences after correction. The receiver operating characteristic curve and area under the curve (AUC) were used to evaluate the diagnostic efficiency of the CEST parameters and the combined model. Results:Compared with the NC group, the left SN Amide value, left RN Amide value, and right SN NOE value were reduced in the PD group, and the difference was statistically significant ( t=-3.59, corrected P=0.026; t=-3.77, corrected P=0.016; Z=-3.27, corrected P=0.017). The left SN Amide value, the left RN Amide value, the right SN NOE value, and the combined model all had good diagnostic efficacy in the differentiation of the PD group from the HC group (AUCs of 0.78, 0.79, 0.75, and 0.81, respectively). The combined model had the highest AUC value (0.81) and specificity (97.78%), the Amide value of left SN had the highest sensitivity (93.33%). Conclusions:Quantitative analysis of CEST-MRI based on the 4-pool Lorentz fitting model shows significant differences in the CEST quantitative indicators of the SN and RN between the PD group and the NC group, demonstrating good potential for clinical application in the diagnosis of PD.
