Objective:Bibliometric analysis was performed to map scientific knowledge landscape, so that to explore the research status and future trends in the field of carbapenem-resistant Gram-negative bacteria (CRGNB) over the past decade.Methods:Literature on CRGNB published between January 1st, 2015 and December 31st, 2024 was retrieved from the China National Knowledge Internet (CNKI) database and Web of Science Core Collection (WoSCC). VOSviewer and CiteSpace were used for bibliometric analysis.Results:A total of 3 340 Chinese and 10 761 English publications were included in this study. The annual Chinese publications remained stable, while English publications exhibited a linear growth. It was anticipated that the English publications would decline in the forthcoming years, although remaining high. China contributed the highest number of publications, and Zhejiang University was the institution with the largest number of publications. Bonomo RA, Chen L, etc. were high-impact authors in the field of CRGNB and had formed a stable cooperative group. Antimicrobial Agents and Chemotherapy was the journal with the largest number of publications. High-frequency keywords in the domain of CRGNB were comprehensively categorized into four distinct clusters, including carbapenem resistance mechanisms and gene transmission, antimicrobial drugs and combination therapy, management of critically ill patients, and infections and colonization. It was imperative to acknowledge the significance of all of these research areas. Burst word analysis suggested that carbapenem-resistant Enterobacterales virulence genes as well as new isoforms of Klebsiella pneumoniae carbapenemase (KPC) had become a research hotspot. Conclusions:The issue of carbapenem resistance remains a significant concern. Current research focus on the resistance mechanisms and antimicrobial agents, highlighting its significant academic advancement and practical applications. Fostering international collaboration through academic exchanges between research teams worldwide is imperative to establish robust cooperative relationships, facilitate multidisciplinary cooperation, and promote high-quality research.

Transient receptor potential vanilloid-1(TRPV1) channel is a non-selective ligand-gated cationic channel with multiple activation mechanisms in the transient receptor potential subfamily. In recent years, a large number of studies have found that TRPV1 plays an important role in the field of cardiovascular diseases such as hypertension and atherosclerosis. With the in-depth study of traditional Chinese medicine, it has been found that Chinese medicine monomers and their active components can activate or inhibit TRPV1 channels, which has certain potential in the study of cardiovascular diseases. In this paper, the role of TRPV1 channel in cardiovascular diseases and the research progress of traditional Chinese medicine prevention and treatment of cardiovascular diseases based on TRPV1 channel are reviewed, in order to provide new ideas for prevention and treatment of cardiovascular system diseases.

The glymphatic system is a unique network of the central nervous system that facilitates the removal of metabolic waste from the brain and maintains homeostasis.The glymphatic system is relatively active during sleep,and its physiological function is affected by many factors.The application of non-invasive imaging techniques to evaluate the function of the glymphatic system has promoted the development of clinical studies.More and more studies have demonstrated the association between the function of glymphatic system and the pathogenesis of neurodegenerative diseases,cerebrovascular diseases and other central nervous system diseases.The glymphatic system is expected to become a novel target for predicting prognosis of central nervous system diseases and clinical effects.

Endothelial progenitor cells (EPCs) are immature endothelial cells that can proliferate and differentiate into mature endothelial cells. After vascular injury, EPCs migrate from the bone marrow to the ischemic area, participating in damaged endothelial repair and neovascularization, providing a new potential therapeutic approach for vascular diseases including ischemic stroke. This article reviews the feasibility and limitations of EPCs as potential therapeutic targets for ischemic stroke.

Skin injuries always disturb people's normal life, even seriously damage the body health. Thus, it is very necessary to use medical dressings to protect and treat skin wounds. Compared with traditional dressings, novel biological dressings develop more rapidly and their application scope is gradually expanding. Collagen is a natural biological material that can promote wound healing and it also has unique functional advantages in care and treatment. At present, collagen-based medical dressings has become one of the preferred choices to assist wound healing. The authors summarize the source, functional advantages and product classification of collagen-based dressings, and introduce the characteristics and applications of various collagen-based dressings, to provides a reference for further research of the collagen-based wound dressings.

Objective:To retrospectively analyze the clinical characteristics of patients with coronavirus disease 2019 (COVID-19) accompanied with diarrhea.Methods:From January 11 to February 6 in 2020, the clinical data of 663 patients diagnosed with COVID-19 admitted to Renmin Hospital of Wuhan University were collected and divided into diarrhea group and non-diarrhea group according to whether they had diarrhea or not. The differences in baseline characteristics, basic disease history, clinical manifestations, chest computed tomography (CT), laboratory findings, disease severity and mortality between the two groups were compared. Chi-square test and Fisher exact test were used for statistical analysis.Results:Among 663 COVID-19 patients, 70 (10.6%) patients accompanied with diarrhea. The proportion of fatigue and increased lactate dehydrogenase (LDH) levels of diarrhea group were higher than those of non-diarrhea group (58.6%, 41/70 vs. 28.2%, 167/593; and 64.2%, 43/67 vs. 50.4%, 277/550), and the differences were statistically significant ( χ2=26.891 and 4.566, both P<0.05). There was no statistically significant difference in the proportion of pneumonia in chest CT between diarrhea group and non-diarrhea group (100.0%, 62/62 vs. 99.4%, 529/532) ( P>0.05). There were no statistically significant differences in the proportions of mild and normal type, severe type and critical type between diarrhea group and non-diarrhea group (35.7%, 25/70 vs. 38.6%, 229/593; 50.0%, 35/70 vs. 47.2%, 280/593; and 14.3%, 10/70 vs. 14.2%, 84/593, respectively) (all P>0.05). There were no statistically significant differences in the mortality of mild and normal type, severe type and critical type between diarrhea group and non-diarrhea group (0 vs. 0.5%, 3/593; 0 vs. 0 and 1.4%, 1/70 vs. 3.5%, 21/593) (all P>0.05). Conclusions:Patients with COVID-19 accompanied with diarrhea are more likely to have fatigue and increased LDH level. Diarrhea is not significantly correlated with the disease severity of patients with COVID-19.
