Objective To assess the accuracy and consistency of point-of-care testing(POCT)technology in detecting D-dimer(DDI),Procalcitonin(PCT),and N-terminal pro B-type natriuretic peptide(NT-proBNP)in whole blood samples,as well as to validate its feasibility for rapid clinical diagnosis.Methods From July 8 to August 22,2022,a total of 104 paired DDI whole blood and plasma samples,496 paired PCT whole blood and serum samples,and 77 paired NT-proBNP whole blood and serum samples were collected.The consistency and accuracy of test results between whole blood and plasma/serum samples were assessed using the Mann-Whitney U test,regression analysis,relative sensitivity,relative specificity,Youden's index,and Kappa value.Results The test results of DDI,PCT,and NT-proBNP in whole blood and plasma/serum samples demonstrated excellent consistency,with correlation coefficients of r2=0.951 2,r2=0.942 8,and r2=0.991 6,respectively,and all P-values exceeding 0.05.At the medical decision levels,for DDI(0.55 μg/mL),the relative sensitivity,rela-tive specificity,Youden index,and Kappa value were 94.3%,94.1%,0.88,and 0.87,respectively.For PCT(0.5 ng/mL and 2.0 ng/mL),the relative sensitivities were 97.4%and 89.0%,the relative specificities were 95.8%and 98.3%,the Youden indices were 0.93 and 0.87,and the Kappa values were 0.93 and 0.89,respectively.For NT-proBNP(125 pg/mL),the relative sensitivity was 94.1%,the relative specificity was 100%,the Youden index was 0.94,and the Kappa value was 0.87.These findings confirm the high accuracy of whole blood sample testing and the strong concordance between the two methods.Conclusions This study confirmed the efficacy of POCT technology for detecting DDI,PCT,and NT-proBNP in whole blood samples.The results showed a high level of consistency compared to traditional plasma/serum methods,thereby reinforcing the clinical applicability of POCT for rapid diagnosis.

In recent years， the incidence of pulmonary nodules has kept rising. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of pulmonary nodules and identify the breakthrough points of integrating TCM with Western medicine， the China Association of Chinese Medicine organized medical experts in TCM and western medicine to carry out in-depth discussion regarding this disease. The discussion encompassed the modern medical advances， TCM theories of etiology and pathogenesis， the role and advantages of TCM in the whole course management of pulmonary nodules， contents and methods of research on pulmonary nodules， and science popularization work， aiming to provide a reference for clinical practice and scientific research. After discussion， the experts concluded that the occurrence of pulmonary nodules was rooted in the deficiency of the lung and spleen and triggered by phlegm dampness， blood stasis， and Qi stagnation. TCM can treat pulmonary nodules by controlling and reducing nodules， improving physical constitution， ameliorating multi-system nodular diseases， reducing anxiety and avoiding excessive diagnosis and treatment， and serving as an alternative for patients who are unwilling or unfit for surgical treatment. At present， the optimal diagnosis and treatment strategy for pulmonary nodules has not been formed， which needs to be further studied from multiple perspectives such as clinical epidemiology， biology， and evidence-based medicine. The primary task of current research is to find out the advantages， effective prescriptions， and target populations and determine the effective outcomes of TCM in the treatment of pulmonary nodules. At the same time， basic research should be carried out to explore the etiology and biological behaviors of pulmonary nodules. The expert consensus on the diagnosis and treatment of pulmonary nodules with integrated TCM and Western medicine needs to be continuously revised to guide clinicians to conduct standardized， scientific， and accurate effective diagnosis and treatment.

It uses research methods such as questionnaire surveys and in-depth interviews with key informants to investigate the quantitative data,settlement costs,satisfaction,and other actual operations of the"dual channel"electronic prescription circulation and medical insurance online settlement pilot project in Shenzhen in June 2022.It explores and analyzes its advantages in effectively eliminating counterfeit paper prescriptions,real-time sharing of pharmacy inventory,transparency of drug prices,and limitations in prescription circulation coverage.And it makes suggestions for optimizing the prescription review process,such as creating a unified and standardized prescription circu-lation model,constructing a standardized and efficient management system for purchased drug catalogs,and strengthening information privacy and data security,are proposed.
