ABSTRACT
Objective:To evaluate the quality, content and feasibility of health information on breast cancer treatment in Chinese websites, for reference in standardizing online health information.Methods:In January 2022, three Chinese search engines, namely Baidu, Sogou and Haosou, were used to search with " breast cancer" and " breast cancer treatment" as keywords. The first 50 links identified by each engine were accessed to screen breast cancer treatment health information websites. Subsequently, the DISCERN scoring tool was adopted to evaluate the quality of health information on the websites(16 items). The information content(10 items)assessment was conducted by referring to the " Guidelines and Specifications for Breast Cancer Diagnosis and Treatment of the Chinese Anti-Cancer Association(2019 Edition)". The feasibility of website health information was evaluated with Patient Education Materials Assessment Tool(PEMAT).Results:A total of 19 websites were included, and their service mode was mainly active information service(14 websites). The overall scoring for the quality of health information about breast cancer treatment was 2.0, with the highest score of " clarity of purpose" (3.4). According to the assessment results of information content, these websites were divided into 4 grades: excellent(3), good(11), fair(3), and poor(2). All the websites contained the information on clinical manifestations, etiology, examination and treatment of breast cancer. The overall feasibility of website health information was 44.5%, indicating incomplete feasibility.Conclusions:The Chinese website′s health information on breast cancer treatment is poor in quality and implementation. Hence, it′s urgent to further improve and standardize online health information, establishing a unified evaluation standard and actively exploring the new mode of " Internet+ Medical" service.
ABSTRACT
Objective To investigate the diagnostic value of bronchoscopy in smear negative pulmonary tuberculosis.Methods 65 cases with cavernous and 35 non -cavernous negative smear pulmonary tuberculosis were examined by bronchoscopy.Results The positive rates of sputum examination in the empty group,the non empty group and the total sputum examination were 49.2%,17.1% and 38%,respectively.There was statistically signifi-cant difference in sputum positive rate between empty group and non empty group (χ2 =9.942,P =0.002).The posi-tive rate of sputum was 28%.The positive rate of sputum negative and sputum positive rate was 10% after operation. Microscopically visible tracheal and bronchial abnormalities,tracheal inflammatory change rates of empty group and non empty group were 52.3%,40.0%,the difference between the two groups had no statistically significant difference (χ2 =1.381,P =0.240).The tracheal stenosis rates of hole group and non empty group were 9.0% and 11.4%,the difference between the two groups had no statistically significant difference (χ2 =0.122,P =0.727).The overall trachea abnormal changes rate was 58.0%,including inflammatory change rate 48.0% and 10.0% stenosis rate. Conclusion Bronchoscopy has significant clinical value in smear negative pulmonary tuberculosis,especially with cavernous.The positive rate will be promoted after bronchoscopy,and can find abnormal changes of tube.
ABSTRACT
Objective To investigate the value of adenosine deaminase( ADA) for the diagnosis of tubercu-lous pleural effusion.Methods A retrospective analysis was made of 324 cases of tuberculous pleural effusion patients which were effective treated and 68 cases were diagnosed of malignant pleural effusion.By drawing receiver operating characteristic curve, the best threshold of diagnosing of tuberculous pleural effusion was determined,and the distribution characteristics of ADA in tuberculous pleural effusion were analyzed.Results When the ADA was set at 19.5U/L it was good for identifying tuberculous empyema and tuberculous pleurisy.The activity of ADA in group of different gender did not have significant difference(Z=-0.572,P=0.283).The activity of ADA had significant difference between tuberculous empyema with tuberculous pleurisy patients(Z=-2.317,P=0.01),and the same as in group of different ages between less than or equal to 45 years old with the others(Z=-2.387,P=0.008).The activity of ADA had significant difference between tuberculous empyema and tuberculous pleurisy patients of younger than 45 years old(Z=-2.740,P=0.003),but not in the group of less than or equal to 45 years old (Z=-0.267, P=0.390).Conclusion The activity of ADA is good for identifying diagnosis of tuberculous pleural effusion and malignant pleural effusion, especially in tuberculous empyema and less than or equal to 45 years old patients.The standard of diagnosis and the nature of the tuberculous pleural effusion may affect the cut-off value of ADA.
