RESUMO
Objective To observe the changes in serum a proliferation inducing ligand(a proliferation inducing ligand,APRIL)and N-myc downstream regulated gene 1(N-myc downstream regulated gene 1,NDRG1)levels,and analyze their diagnostic value for ovarian endometrioma(OEM).Methods From July 2021 to July 2022,132 patients with OEM who visited Zigong First People's Hospital were regarded as the observation group,and regular follow-up was conducted.According to the prognosis of these patients,they were grouped into the recurrence group(n=50)and the non recurrence group(n=82).Meanwhile,78 healthy individuals who had their medical checkups at the hospital during the same period were the control group.Enzyme linked immunosorbent assay(ELISA)was applied to detect serum APRIL and NDRG1 levels,and the general data of the recurrent and non recurrent groups were compared.Logistic regression analysis was applied to analyze the relevant factors affecting the prognosis of OEM.Pearson analysis was applied to explore the correlation between serum APRIL and NDRG1 levels in patients with OEM.Receiver operating characteristic(ROC)curve was applied to evaluate the diagnostic value of serum APRIL,NDRG1 levels and their combination for OEM.Results Compared with the control group,APRIL level(35.28±6.81ng/ml vs 26.37±3.19ng/ml)and NDRG1 level(124.39±15.67μg/L vs 9.67±10.82μg/L)in observation group were increased,and the differences were significant(t=10.864,17.278,all P<0.05).Compared with the non recurrence group,the serum levels of APRIL(40.38±7.88ng/ml vs 32.16±6.18ng/ml)and NDRG1(132.04±19.83μg/L vs 119.73±13.16μg/L)in the recurrence group were increased,and the differences were significant(t=6.668,4.287,all P<0.05).Logistic regression analysis showed that serum APRIL and NDRG1 levels were risk factors for the prognosis of patients with OEM(Waldχ2=11.839,28.437,all P＜0.001).Pearson method analysis results showed a positive correlation between serum APRIL level and NDRG1 level in patients with OEM(r=0.439,P<0.001).The area under the curve(AUC)of combined diagnosis of serum APRIL and NDRG1 levels in patients with OEM was 0.849,with a sensitivity and specificity of 73.95%and 85.37%,respectively,which was better than the single prediction of APRIL and NDRG1(Z =2.644,2.094,P=0.008,0.036).Conclusion The serum levels of APRIL and NDRG1 were increased in patients with OEM.The combination of the two has high clinical value in the diagnosis of OEM,which may be closely related to the prognosis of patients with OEM.
RESUMO
Objective:To compare research hotspots in digital transformation of higher education in China and abroad and analyze the research trends through the bibliometric method and text analysis method, and to offer advice and suggestions for digital transformation of higher education in China.Methods:The relevant literature in Web of Science and China National Knowledge Infrastructure from the establishment of the databases to April 1, 2023 were retrieved. Citespace and VOSviewer were used to visually compare the research hotspots and trends in digital transformation of higher education in China and abroad from the perspectives of number of published papers, journal, author, country, cooperation network, keyword co-occurrence and clustering, and keyword burst.Results:The results showed that both international and domestic researchers paid attention to the practical significance and development model of digital transformation of higher education in the context of rapid development of science and technology and the post-pandemic era. International researchers emphasized the advantages and disadvantages of digital transformation from the aspects of connotation, practice logic, and theoretical framework, while Chinese researchers focused on clarifying the principles related to digital transformation, summarizing the experience of other countries, and exploring the development path. The application of educational technology and the digital literacy of teachers and students had become research hotspots in China and abroad.Conclusion:The research on digital transformation of higher education has gradually shifted from theoretical system to practice effect. In the future, with the continuous deepening of theoretical research, how to improve the effectiveness of digital transformation of higher education is a research direction worthy of attention.
