Objective To analyze the status of willingness to participate in health science popularization (HSP) and its influencing factors among medical workers in Guangdong Province. Methods A total of 462 medical workers in Guangdong Province were recruited as the study subjects using a stratified convenience sampling method. The Questionnaire on Influencing Factors of Willingness to Participate in Health Science Popularization, developed by the research team, was used to investigate their willingness to participate in HSP and related variables, including previous communication experience, attitude, moral belief, descriptive norm, injunctive norm, self-efficacy, and social support. Hierarchical regression analysis was used to identify the influencing factors of willingness to participate in HSP. Results The median and 25^th and 75^th percentiles score of willingness to participate in HSP was 4.0 (3.8, 4.5), indicating a moderately high level of willingness. The HSP participation willingness score was positively correlated with scores for previous communication experience, attitude, moral belief, descriptive norm, injunctive norm, self-efficacy, and social support (Spearman correlation coefficients were 0.513, 0.384, 0.507, 0.533, 0.463, 0.556, and 0.435, respectively; all P<0.01). Hierarchical regression analysis showed that previous communication experience, moral belief, descriptive norm and self-efficacy positively predicted willingness to participate in HSP (all P<0.05). Medical workers in the non-Pearl River Delta region had lower willingness than those in the Pearl River Delta region for HSP participation (P<0.05). Conclusion There is still room for improving willingness for HSP participation among healthcare professionals in Guangdong Province. It is recommended to enhance self-efficacy through communication skills training, strengthen professional ethics education, foster a positive peer engagement atmosphere, and intensify resource support and capacity building for HSP in the non-Pearl River Delta region, to improve HSP participation willingness among medical workers in Guangdong Province.

Objective To investigate the application of hematology analyzer in cell counting of serous cavity effusion .Methods Humoral mode of Sysmex XE-5000 automated hematology analyzer and manual microscopy were employed to perform cell counting in 85 samples of serous cavity effusion .Results Compared with the manual method and instrument method ,differences of mononu-clear cells and multinucleated cells of serous cavity effusion showed no statistical significance (P>0 .05) ,while those of leukocytes , erythrocytes were found statistical significance (P<0 .05) .Conclusion Sysmex XE-5000 automated hematology analyzer has advan-tages of simple ,stability and accuracy ,however ,its application in the effusion cell counting can not completely replace the manual microscopy .

Objective To study the relation between the TCM constitution and the lung function of asthmatic bronchitis children to lay a foundation to apply the TCM constitution theory in preventing and treating children asthmatic diseases.Methods Following the Zhu's method,120 asthmatic bronchitis children were divided into normal constitution,phlegm-damp constitution,qi deficiency constitution,internal heat constitution,and both qi and yin deficiency constitution.Based on the Su's method,the cases were classified into balance constitution,lung-spleen Ⅰ constitution,lung-spleen Ⅱ constitution,spleen-kidney Ⅰ constitution,and spleen-kidney Ⅱ constitution.Their lung function was tested and the TPTEF /Te and VPTEF/Ve of each constitution were analyzed.Results Of the 120 cases,37 ones (30.8%) were qi deficiency constitution;33 ones (27.5%) were phlegm-damp constitution;and 60 ones (50.0%) were lung-spleen Ⅱ constitution.Compared with those with normal constitution,the cases with the phlegm-damp constitution,qi deficiency constitution,internal heat constitution,and both qi and yin deficiency constitution had significantly lowered TPTEF/Te and VPTEF/Ve (P
