Ginsenoside Rg_2(GRg2) is a triterpenoid compound found in Panax notoginseng. This study explored its effects and mechanisms on diabetic retinopathy and angiogenesis. The study employed endothelial cell models induced by glucose or vascular endothelial growth factor(VEGF), the chorioallantoic membrane(CAM) model, the oxygen-induced retinopathy(OIR) mouse model, and the db/db mouse model to evaluate the therapeutic effects of GRg2 on diabetic retinopathy and angiogenesis. Transwell assays and endothelial tube formation experiments were conducted to assess cell migration and tube formation, while vascular area measurements were applied to detect angiogenesis. The impact of GRg2 on the retinal structure and function of db/db mice was evaluated through retinal thickness and electroretinogram(ERG) analyses. The study investigated the mechanisms of GRg2 by analyzing the activation of Yes-associated protein(YAP) and Toll-like receptors(TLRs) pathways. The results indicated that GRg2 significantly reduced cell migration numbers and tube formation lengths in vitro. In the CAM model, GRg2 exhibited a dose-dependent decrease in the vascular area ratio. In the OIR model, GRg2 notably decreased the avascular and neovascular areas, ameliorating retinal structural disarray. In the db/db mouse model, GRg2 increased the total retinal thickness and enhanced the amplitudes of the a-wave, b-wave, and oscillatory potentials(OPs) in the ERG, improving retinal structural disarray. Transcriptomic analysis revealed that the TLR signaling pathway was significantly down-regulated following YAP knockdown, with PCR results consistent with the transcriptome sequencing findings. Concurrently, GRg2 downregulated the expression of Toll-like receptor 4(TLR4), TNF receptor-associated factor 6(TRAF6), and nuclear factor-kappaB(NF-κB) proteins in high-glucose-induced endothelial cells. Collectively, GRg2 inhibits cell migration and tube formation and significantly reduces angiogenesis in CAM and OIR models, improving retinal structure and function in db/db mice, with its pharmacological mechanism likely involving the down-regulation of YAP expression.

Objective To explore the clinical effect of 3D-printed interbody fusion cage applied in anterior cervical decompression and bone graft fusion for the treatment of cervical spondylotic myelopathy.Methods A total of 100 patients with cervical spondylotic myelopathy who underwent anterior cervical fusion surgery in our hospital from June 2020 to June 2023 were selected as the research subjects,they were randomly divided into the 3D group and the control group according to the random number table method,with 50 cases in each group.Patients in the 3D group were implanted with a 3D-printed interbody fusion cage which was made of microporous metal materials,while patients in the control group were implanted with intervertebral fusion cage which was made of polyetheretherketone material.The surgery-related indicators,cervical imaging parameters,cervical spinal cord function,cervical axial function and surgical complications of patients between the two groups were compared.Results There was no statistically significant difference in the operation time,intraoperative blood loss or length of hospital stay of patients between the two groups(P>0.05).The height of the cervical fusion segments and the Cobb angle of the fusion segments of patients in both groups at each time point after the operation were significantly increased compared with those before the operation(P<0.05).The height of the cervical fusion segments and the Cobb angle of the fusion segments of patients 1 month,3 months,and 6 months after the operation in the 3D group were all greater than those in the control group(P>0.05).The subjective symptom score and the total score of the Japanese orthopaedic association(JOA)of patients 6 months after the operation in the 3D group were higher than those in the control group(P<0.05).The cervical axial function of patients 6 months after the operation in the 3D group was better than that in the control group(P<0.05).The incidence of surgical complications in the 3D group was lower than that in the control group(P<0.05).Conclusion The use of 3D-printed interbody fusion cage during the anterior cervical decompression and bone graft fusion for patients with cervical spondylotic myelopathy can significantly improve the clinical symptoms of patients,achieve better cervical axial function,and have fewer complications.

Objective:To construct a nursing norm for extracorporeal membrane oxygenation in adults, so as to provide a reference for improving the nursing care of adult extracorporeal membrane oxygenation.Methods:The first draft was developed through literature search and expert discussion. From September to October 2023, 16 experts were selected using the Delphi method to conduct two rounds of expert consultation on the first draft, and the final draft was revised with reference to the experts' comments. The expert positivity coefficient was expressed as the effective recovery rate of the questionnaire, and the degree of expert authority was evaluated with the authority coefficient, and the degree of harmonization of expert opinions was assessed with the Kendall's harmony coefficient.Results:Literature search screened a total of four guidelines and five expert consensus.

The objective of this study was to observe the effect of Astragalus membranaceus on high sugar-induced Caenorhabditis elegans, and to explore its mechanism of action. UPLC-MS method was used to identify the components of Astragalus membranaceus. A high glucose model was established by using Caenorhabditis elegans as a model organism, and the effects of Astragalus membranaceus on body length, body bending, swallowing frequency, and reactive oxygen species (ROS) of the nematode were determined; the effects of Astragalus membranaceus on the expression of mRNA of genes related to the protein skinhead-1 (SKN-1) signaling pathway were examined by using the real-time fluorescence quantitative polymerase chain reaction (PCR). The results showed that compared with the normal group, the nematode body length, body bending, and swallowing frequency expression were significantly reduced and the ROS content in the body was significantly increased in the high glucose state; after the administration of Astragalus membranaceus, the body length, body bending, and swallowing frequency expression were significantly increased, and the ROS content was significantly reduced (P < 0.01). Compared with the normal group, SKN-1, superoxide dismutas-3 (SOD-3), glutathione S-transferase 4 (GST-4), and glutathione S-transferase 7 (GST-7) expression were significantly decreased in Caenorhabditis elegans in the high glucose condition; SKN-1, SOD-3, GST-4, and GST-7 expression were significantly increased after administration of Astragalus membranaceus (P < 0.01). In the present study, we demonstrated that Astragalus membranaceus has an effect on high glucose-induced Caenorhabditis elegans nematodes, and its mechanism of action may be through the modulation of the SKN-1 signaling pathwaym in order to ameliorate the oxidative stress response induced by high glucose.
