Methods: Forty patients with breast cancer who were treated by the first hospital of Jilin University were selected. All the patients were diagnosed by RTE and pathology. The pathological diagnosis was used as the gold standard to evaluate the benign and malignant tumors. The receiver operating characteristic curve (ROC curve) was used to evaluate the value of RTE in the diagnosis of breast lesions. Results: Of the 52 lesions, 33 were benign and 19 were malignant. Ratio-max and Ratio-mean were significantly different between the benign and malignant groups (P<0.05). The critical point of Ratio-max for benign and malignant nodules was 3.80, the sensitivity, specificity and accuracy of diagnosis were 84.2%, 78.8% and 80.8%, respectively. The critical point of ratio-mean for benign and malignant nodules was 3.15, the sensitivity, specificity and accuracy of diagnosis were 78.9%, 84.8% and 82.6%, respectively. There was no statistically significant difference between Ratio-mean and Ratio-max (Z=0.673, P<0.05). Conclusion: RTE can better distinguish between benign and malignant breast tumors, and combined with two-dimensional and color Doppler ultrasound diagnostic indicators will further improve the diagnostic accuracy.","PeriodicalId":340774,"journal":{"name":"Proceedings of the 3rd International Conference on Medical and Health Informatics","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133111502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a dynamic gene feature extraction method via visibility graph (VG). It is carried out in four stages: 1) complex networks are constructed from gene time series data; 2) different features are extracted based on the network structure and the specific characteristics of VG algorithm; 3) different classifiers are adopted to analyze gene time series data compared with different feature extraction methods, while, clustering algorithm are applied based on dynamic feature extraction via VG to achieve better performance; 4) different datasets are used to verify our method including clarifying and clustering according to the feature we extract. Abundant experiment results prove the effectiveness of VG method's in extracting the time varying and specific gene features underlying realistic complex gene expression data from time series.","PeriodicalId":340774,"journal":{"name":"Proceedings of the 3rd International Conference on Medical and Health Informatics","volume":"34 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114066647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a major challenge of clinicians who use EMRs is the lowered perceived quality of patient-doctor communication and interaction as a result of doctors being distracted with EMR use during consultations. A unique approach to this problem is through applications that automatically document clinical encounters in real-time. This study aims to develop a speech transcriber plugin for a web-based EMR for real-time clinical encounter documentation. We make use of available speech-to-text services on the web as well as cTAKES for clinical annotation. A draft summary of the clinical encounter is presented to the user in editable SOAP format. Blockchain technology for the speech recording is also explored to secure access to the recording. Internal testings showed that the prototype is able to capture audio conversations into text and parse the transcription for medical concepts. However, after a single formal usability evaluation we found that there is much to be done in terms of the usability of the summarization component.","PeriodicalId":340774,"journal":{"name":"Proceedings of the 3rd International Conference on Medical and Health Informatics","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123869709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: The standard Boolean operators were used to determine the search terms for each cardiovascular disease. Spearman correlation analysis was used to explore the correlation among search index values, incidence and mortality rates of the two cardiovascular diseases. The time series decomposition method was used to extract the seasonality and trend of the search index. Results: The Baidu Index was highly correlated with the incidence and mortality of two cardiovascular diseases in China (coronary heart disease: r = 0.961, P < 0.001, stroke: r = 0.833, P < 0.001). The internet search behavior of cardiovascular disease presents a trend of seasonal fluctuations (increased in winter). The East China region has the largest number of searches for two cardiovascular diseases, and the least in the northeast and northwest regions. Conclusion: Search behavior reflects the public's perception of cardiovascular diseases from a different perspective. Researching internet search behaviors provides an innovative and real-time approach to monitor and estimate the disease burden of cardiovascular disease.","PeriodicalId":340774,"journal":{"name":"Proceedings of the 3rd International Conference on Medical and Health Informatics","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114554657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The photoacoustic imaging shows the outperformance to compare with traditional ultrasound imaging. However, it is unknown if the photoacoustic effect changes when the laser misalignment on the reticulated piezoelectric ceramic. Our system is mainly composed of hardware and software, including a piezoelectric ceramic, motors, a class III laser diode, relays, and a data acquisition card combined with LabView™ program. The piezoelectric sensor is a 21.9mm by 15.9mm rectangular ceramic with four strip holes in the center. The laser hits several different spots on strip holes of piezoelectric. The total of 6 points are tested to observe if these signals keep consistence. The results demonstrated the laser mis-alignment effect of photoacoustic imaging can be controlled. Finally, the research tested different samples and analyzed by histogram method to obtain the response signals with different features. This research may help to generate photoacoustic features faster and to improve image quality in the future.","PeriodicalId":340774,"journal":{"name":"Proceedings of the 3rd International Conference on Medical and Health Informatics","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125377655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
