OBJECTIVE: To assess the reliability and validity of Adversity Quotient Scale in evaluating the adversity quotient among nurses. METHODS: A total of 409 nurses were selected as study subjects from three first-class hospitals in Fujian Province by cluster sampling method. The adversity quotient was investigated by Adversity Quotient Scale and its reliability and validity were tested. RESULTS: The Cronbach′s alpha coefficient, Spearman-Brown coefficient, Guttman Split-Harf coefficient and retest reliability of Adversity Quotient Scale were 0.931, 0.826, 0.823 and 0.940, respectively. The content validity ratio of Adversity Quotient Scale was 0.980. The scores of control, attribution, extension and tolerance factors were positively correlated with the total score of Adversity Quotient Scale(correlation coefficients were 0.813, 0.844, 0.874 and 0.822, respectively, P<0.05). Before model modification, the initial model fitting index of confirmatory factor analysis was χ~2/df=3.72, root mean square residual approximate(RMSEA)=0.09, the overall fitting of the model was not high. After model modification, the combined reliability of control, attribution, extension and tolerance factors were 0.780, 0.796, 0.831 and 0.871, respectively. The fitting index of the modified model was χ~2/df=3.08, RMSEA=0.07, showing a good fitting of the model. CONCLUSION: Adversity Quotient Scale has a good reliability and validity in the assessment of nurses, which can be a reliable and effective adversity quotient assessment tool.

Objective:To prepare 99Tc m-hydrazinonicotinamide(HYNIC)-αCD8/Fab ( 99Tc m-αCD8/Fab), and explore the predictive value of 99Tc m-αCD8/Fab SPECT/CT imaging for the efficacy of anti-programmed death-1 (PD-1) immunotherapy. Methods:The αCD8/Fab was modified with HYNIC- N-hydroxysuccinimide (NHS) and IRDye800-NHS to form HYNIC-αCD8/Fab and IRDye800-αCD8/Fab (Dye-αCD8/Fab), respectively. 99Tc m-αCD8/Fab was prepared in sodium bicarbonate buffer (pH=8.5), with SnCl 2 being used as the reducing agent. The labeling yield and radiochemical purity of 99Tc m-αCD8/Fab and its stability in PBS and fetal bovine serum (FBS) were tested in vitro. The mouse spleen and human peripheral blood lymphocytes were isolated for cell-specific binding and blocking experiments of 99Tc m-αCD8/Fab in vitro. SPECT/CT imaging was used to analyze the specific binding ability of the 99Tc m-αCD8/Fab probe in CT26 colon cancer mouse models (BALB/c). The near infrared fluorescence imaging and SPECT/CT imaging were performed to detect the intra-tumoral CD8 + T cell infiltration after anti-PD-1 therapy in tumor bearing mice, and the results were further verified by HE and immunofluorescence staining. CD8 + T cell depletion study was performed to determine the role of CD8 + T cells in the tumor responses to anti-PD-1 therapy. Two-way analysis of variance was used to compare the data difference. Results:The labeling yield of 99Tc m-αCD8/Fab was 90% with a high radiochemical purity (95%) and good stability in vitro (radiochemical purity still more than 80% after 720 min in PBS and FBS). 99Tc m-αCD8/Fab could specifically bind to mouse CD8 + T cells ((10.30±0.81) percent added radioactive dose (%AD)/10 6 cells), compared with the binding ability in human peripheral blood lymphocytes group and CD8 antibody blocking group ((1.78±0.61) and (1.59±0.25) %AD/10 6 cells; F=10.07, P<0.001). SPECT/CT imaging showed that 99Tc m-αCD8/Fab had markedly higher tumor uptake in the CT26 colon cancer mouse models. Near-infrared fluorescence imaging showed that the tumor uptake of 99Tc m-αCD8/Fab in the responsive group was significantly higher than in the nonresponsive group after anti-PD-1 treatment ((8.9±1.1)% vs (7.1±0.8)%; F=4.69, P=0.024), and SPECT/CT imaging found the similar result. HE and immunofluorescence staining of tumor and lymph nodes showed that the proportion of lymphocyte infiltration was higher in the responsive group. Furthermore, CD8 + T cell depletion significantly reversed the therapeutic effect of anti-PD-1 immunotherapy in tumor-bearing mice. Conclusions:In this study, 99Tc m-αCD8/Fab was successfully obtained. CD8-specific SPECT imaging could sensitively visualize the tumor-infiltrating CD8 + T cells, suggesting the potential application value to predict and evaluate the efficacy of immunotherapy in the clinical settings.
