Diabetic retinopathy(DR)is a prevalent microvascular complication of diabetes and a leading cause of vision loss globally.Although anti-vascular endothelial growth factor(anti-VEGF)therapies remain the clinical mainstay, a significant proportion of patients exhibit suboptimal responses, highlighting the urgent need for novel therapeutic targets. Calcitonin gene-related peptide(CGRP), a multifunctional neuropeptide, is gaining attention due to its roles in vascular regulation, neuroprotection, and immunomodulation. This review summarizes the biological characteristics of CGRP and its receptor-mediated signaling, and explores emerging evidence of CGRP's involvement in DR through its vasodilatory effects and regulatory effect on neurodegenerative disorders and release of inflammatory cytokines. Furthermore, the therapeutic potential of targeting the CGRP pathway in DR is evaluated, especially in cases unresponsive to VEGF inhibition. Despite currently the lack of CGRP-targeted drugs applied for DR, the peptide demonstrates efficacy and safety in other diseases, such as migraine, suggests promising translational opportunities. However, CGRP may play a dual role in different pathological stages of DR, thus its treatment strategy needs to be considered precisely. Future research elucidating the precise mechanisms of CGRP in DR may pave the way for innovative intervention strategies.

In situ and real-time monitoring of responsive drug release is critical for the assessment of pharmacodynamics in chemotherapy. In this study, a novel pH-responsive nanosystem is proposed for real-time monitoring of drug release and chemo-phototherapy by surface-enhanced Raman spectroscopy (SERS). The Fe3O4@Au@Ag nanoparticles (NPs) deposited graphene oxide (GO) nanocomposites with a high SERS activity and stability are synthesized and labeled with a Raman reporter 4-mercaptophenylboronic acid (4-MPBA) to form SERS probes (GO-Fe3O4@Au@Ag-MPBA). Furthermore, doxorubicin (DOX) is attached to SERS probes through a pH-responsive linker boronic ester (GO-Fe3O4@Au@Ag-MPBA-DOX), accompanying the 4-MPBA signal change in SERS. After the entry into tumor, the breakage of boronic ester in the acidic environment gives rise to the release of DOX and the recovery of 4-MPBA SERS signal. Thus, the DOX dynamic release can be monitored by the real-time changes of 4-MPBA SERS spectra. Additionally, the strong T2 magnetic resonance (MR) signal and NIR photothermal transduction efficiency of the nanocomposites make it available for MR imaging and photothermal therapy (PTT). Altogether, this GO-Fe3O4@Au@Ag-MPBA-DOX can simultaneously fulfill the synergistic combination of cancer cell targeting, pH-sensitive drug release, SERS-traceable detection and MR imaging, endowing it great potential for SERS/MR imaging-guided efficient chemo-phototherapy on cancer treatment.

Objective:To investigate the current status of emotional labor of nurses in standardized training period, and to analyze the relationship between emotional labor and emotional intelligence.Methods:From May to June 2020, 312 nurses in the standardized training period were selected as the research objects, which were investigated with general information questionnaire, Emotional Labor Scale and Emotional Intelligence Scale.Results:The total score of standardized training nurses' emotional labor was (52.27±10.18) points, and the total average score of items was (3.73±0.73) points. The average scores of the three dimensions from high to low: deep acting (4.62±0.86) points, expression of genuine emotion (3.62±0.99) points and surface acting (3.42±0.95) points. There was a correlation between emotional intelligence and emotional labor. Multiple linear regression analysis showed that the emotional evaluation of others ( β value was -0.189, P<0.05) ( β value was -0.255, P<0.01). Self emotional assessment ( β value was 0.297, P<0.01) ( β value was 0.177, P<0.05). Self emotional assessment ( β value was 0.269, P<0.05), which had a positive predictive effect on emotional expression requirements. Conclusions:The emotional labor of nurses in standardized training period is at the medium level, and the deep acting score is the highest between three dimensions. Hospital managers could promote nurses to use appropriate emotional labor strategies by strengthening the cultivation of emotional intelligence during standardized training period.

Objective:To explore the mediating role of occupational benefit in the emotional intelligence and emotional labor of nurses during the standardized training period, so as to provide references for enhancing the professional adaptation potential of nurses during the standardized training period.Methods:This study was a cross-sectional study. Using the convenient sampling method, a total of 318 standardized training nurses from the Fifth Affiliated Hospital of Sun Yat-sen University and the First Affiliated Hospital of Nanchang University were selected as research objects from May to June 2020. They were investigated by general data questionnaire, Emotional Intelligence Scale, Occupational Benefit Scale and Emotional Labor Scale. Structural equation model (SEM) was used to explore the mediating effect of occupational benefit on emotional intelligence and emotional labor.Results:A total of 318 questionnaires were collected in this study, among which 312 were valid. The mean scores of items of emotional intelligence and occupational benefits of 312 nurses were (3.69±0.52) and (3.97±0.54) , respectively. The average scores of the three dimensions of emotional labor were surface acting (3.42±0.95) , emotional expression requirements (3.62±0.99) and deep acting (4.62±0.86) . There were correlations between emotional intelligence, occupational benefit and emotional labor (all P<0.05) . The structural equation model showed that the emotional intelligence and occupational benefit of nurses in the standardized training period had direct predictive effects on emotional labor, and emotional intelligence also indirectly affected emotional labor with occupational benefit as an intermediary variable. The structural equation fitting index χ 2/ df was 1.731, the goodness of fit index was 0.949, the adjusted goodness of fit index was 0.912 and the root mean square error of approximation was 0.058. Conclusions:Occupational benefit has a partial mediating effect between the emotional intelligence and emotional labor of nurses during the standardized training period. Nursing managers can take effective measures to improve the emotional intelligence level of nurses during the standardized training period, enhance the sense of occupational benefit and optimize their emotional labor performance from individual factors.
