BackgroundGlobally, several generations of doctors in the field of lymphedema have created numerous publications. To date, no bibliometric analysis has been performed specifically on these publications. For the further promotion of research on lymphedema and to align with the international research frontiers, it is essential to understand the current state of Lymphedema research output.ObjectiveThis study aims to statistically and visually analyze the characteristics of publications output, distribution of contributions and development process of lymphedema, enriching the knowledge base of Lymphedema, and then seek potential research topics and collaborators.MethodsBased on the Web of Science core collection database, we firstly analyzed the quantity and quality of publications in the field of lymphedema, secondly profiled the publishing groups in terms of country, institution, author’s publication and cooperation network, and finally sorted out and summarized the hot topics of research.ResultsA total of 8569 papers were retrieved from 1900-2021. The top4 journals with the most publications were LYMPHOLOGY, LYMPHATIC RESEARCH AND BIOLOGY, PLASTIC AND RECONSTRUCTIVE SURGERY and ANNALS OF SURGICAL ONCOLOGY. The top 4 countries with the most publications were USA, Japan, UK, and China. The United States dominates the total number of publications and the international cooperation network. The most productive research institution is Harvard University, and the research institution with the most collaborating institutions is Memorial Sloan Kettering Cancer Center. Mortimer, Peter S contributes the most research in this field. The research achievements of Japanese scholars in this field are of great significance. The top 5 ranked keywords are “Breast Cancer”, “Health-Related Quality Of Life”, “Lymphscintigraphy”, “Lymphovenous Anastomosis”, and “Lymphangiogenesis”.ConclusionMore and more scholars are devoted to the research of cancer-related Lymphedema. It is foreseeable that breast cancer-related lymphedema and lymphangiogenesis will remain a focus of future research. Advances in Lymphatic vessel imaging and the development of lymphatic microsurgery will further play a role in the clinical workup of lymphedema. Meanwhile, This study can help researchers identify potential collaborators and partner institutions and contribute to further research.

The study aims to explore the comprehensive reasons for patients' non-compliance with graded elastic compression stockings (GECS) as the treatment for lower limb varicose veins. Phenomenological analysis was applied in this qualitative study. The patients diagnosed with lower limb varicose veins and undergoing elective surgery who showed non-compliance with GECS as the treatment were invited to have semi-structured, in-depth, face-to-face interviews. Colaizzi method was employed to analyze the data for emerging themes associated with the reasons for patients' non-compliance. Four main themes and nine subthemes related to the reasons for non-compliance with GECS for lower limb varicose veins were summarized. The main themes that emerged were (1) gaps in the knowledge of GECS therapy as a treatment for lower limb varicose veins, (2) few recommendations from the doctors and nurses, (3) disadvantages of GECS, and (4) sociopsychological factors. These themes provide data for policy and planning to improve patients' compliance with GECS in China. Patients, healthcare professionals, and policy makers should share the responsibility to improve patients' compliance with GECS therapy.

The asymmetric unit of the title compound, C9H9N2+·0.5C8H4O4−·H2O, contains one 2-phenylimidazolium cation, half a benzene-1,3-dicarboxylate anion and one water molecule. In the crystal, components are connected by N—H...O and O—H...O hydrogen-bonding interactions into a three-dimensional network.

Nuclear factor (NF)-κB expression occurs during sciatic injury. In addition, 7,8-dihydroxycoumarin exhibits a neurotrophic effect on peripheral nerve regeneration. To investigate the effects of 7,8-dihydroxycoumarin on the expression levels of NF-κB in L4-6 spinal cord segments of the injured sciatic nerve in mice and on the functional recovery and regeneration following nerve injury, a total of 160 healthy adult male BALB/c mice underwent unilateral sciatic nerve interruption and anastomosis. The mice were separated into groups and subsequently treated with physiological saline (control) or high, medium or low doses of 7,8-dihydroxycoumarin. NF-κB levels were detected by western blot analysis and quantitative polymerase chain reaction (qPCR), and the sciatic functional index (SFI) was measured. Neuronal apoptosis was detected by terminal-deoxynucleotidyl transferase dUTP-mediated nick-end labeling (TUNEL) staining. The results revealed that NF-κB was activated in the L4-6 spinal cord connected to the injured sciatic nerve. qPCR and western-blot analysis results showed that the expression levels of NF-κB in the high- and medium-dose groups were significantly lower compared with the low-dose and control groups at 12 h, one day, three days, five days and one week (P<0.05 for each). SFI and TUNEL results demonstrated that the high- and medium-dose groups exhibited improved functional nerve regeneration and reduced apoptosis compared with the low-dose and control groups. In conclusion, 7,8-dihydroxycoumarin is capable of suppressing the immune activation of NF-κB in the neurons of the L4-6 spinal cord connected with the injured sciatic nerve, thereby reducing the focal filtration of inflammatory cells, producing the optimum environment for nerve regeneration.
