Among the many indicators, we selected radial blood flow, radial artery resistance index, and anastomotic diameter as monitoring indicators. The results of preoperative, immediate postoperative, postoperative 1 day, 3 days, 7 days, and 14 days were used to find the trend of the indicator and determine the best monitoring time point. Finally, we found morphological indicators and hemodynamic parameters changed significantly after operation; no obvious statistical difference between 1 day postoperative and other postoperative monitoring time points were founded. So, ultrasonography has unique advantages in hemodynamics and morphological examination. It can evaluate the functional status of AVF and the efficacy of PTA accurately, and we believe that the first day after surgery is the best time to monitor.","PeriodicalId":136995,"journal":{"name":"2019 IEEE 7th International Conference on Bioinformatics and Computational Biology ( ICBCB)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131155640","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}

Recently, computerized non-invasive diagnostic methods inspired by Traditional Chinese Medicine (TCM) have proved to be reasonable and effective using the face and/or tongue to perform disease detection. These methods no longer require bodily fluids to be extracted (e.g., a blood test), which further relieves the pain of patients and allows doctors to focus on more labor intensive activities. In this paper, we propose a novel classifier based on the fusion of the linear discriminant analysis (LDA) and the sparse representation based classifier (SRC) named L-SRC, to perform disease detection. Specifically, we collect facial images using a non-invasive capture device from those suffering from hyperuricemia, hysteromyoma and prediabetes, and feed it to the L-SRC classifier to perform classification. The experimental results show that L-SRC can discriminate samples belonging to the three classes with healthy control more effectively, achieving accuracies of 72%, 70.95% and 76.60% respectively. This indicates a promising application prospect in the future.","PeriodicalId":136995,"journal":{"name":"2019 IEEE 7th International Conference on Bioinformatics and Computational Biology ( ICBCB)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122017321","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 gold standard for the diagnosis of nephropathy is still renal puncture biopsy, which is an invasive examination and has many contraindications. We proposed to analyze renal ultrasound images using deep learning method to achieve noninvasive assessment. However, the kidney ultrasound images with accurate pathological diagnosis are relatively difficult to collect, which belongs to the category of few-shot learning. To mitigate the impact of few data on performance, this paper proposed a conceptually simple, flexible, and mixed framework for aided diagnosis of nephropathy. Our method, called the PASnet, consists of pretrained network and siamese network. Pretrained network trained by abundant samples from ImageNet can achieve fast convergence and better performance on a new data set. Siamese network learns to converge or disperse image pairs in distance space according to whether it comes from the same class or not. PASnet combines the advantages of these two methods and obtains a better classification performance on nephropathy classification through joint training. Accuracy of PASnet increases by 5.89% compared to a single network.","PeriodicalId":136995,"journal":{"name":"2019 IEEE 7th International Conference on Bioinformatics and Computational Biology ( ICBCB)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133204693","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}

With 5 categories of herbal medicines and 3 to 4 geographical origins for each category, 8 pattern recognition algorithms prove the feasibility of the classification task and SVM, LDA and BP neural network have shown better classification accuracy. Additionally, feature engineering approaches are used to facilitate classification, showing that normalization based on each feature and each sensor and centralization prove to be better normalization approaches for classifiers; a proper degree of noise addition help classifiers get better generalization ability; finally, feature selection with SNR could lead to more efficient classifiers by selecting the most meaningful features and disregarding unnecessary features.

Traditional treatments such as drug therapy and surgery often have little effect on such diseases, and fail to meet the growing medical needs of this age-group. Stem cell-based regenerative medicine is expected to become the third treatment option after drug therapy and surgery.

There are mainly two research methods, namely experimental method and calculation method. Experimental method can obtain more accurate experimental results, but it takes a long time and the cost of manpower, material resources are relatively high. So it is not convenient to obtain experimental results more quickly. Calculation method mostly uses computer and machine learning methods for prediction. Calculation method improves prediction speed to some extent, but the result is not satisfactory. In order to further improve the accuracy of epitope prediction, this paper proposes a novel method of processing epitope characteristics. In this paper, we choose six properties to study. The six main physicochemical properties are converted into corresponding digital vectors, resulting in high-dimensional features. Then we use Principal Component Analysis (PCA) method to process them. Finally, dimensionality reduction features are used as input of Recurrent Neural Network (RNN) for epitope prediction, and good prediction results are obtained. PCA method reduces feature dimensions and facilitates the processing of features. At the same time, the prediction results obtained with dimensionality reduction features show that dimensionality reduction reduces dimensions, but it retains the main components of original features and improves the rate of successful prediction.","PeriodicalId":136995,"journal":{"name":"2019 IEEE 7th International Conference on Bioinformatics and Computational Biology ( ICBCB)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130486922","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}
