The invention discloses a computer aided model construction method based on deep learning gastric cancer pathological sections, and belongs to the technical field of artificial intelligence. The method uses a 121-layer dense-connected convolutional neural network to perform image recognition. A dense block structure in a DenseNet allows the high-level part of the network to acquire shallow features, which greatly reduces the over-fitting phenomenon. At the same time, the model has a large number of layers, which can fit more complex and smoother decision functions. Although the number of layers is large, the number of parameters of the model is not large, which saves resource consumption. In order to further avoid over-fitting, a training mechanism for migration learning is adopted. The model will be pre-trained on an ImageNet dataset to give the model a strong image feature extraction capability. The main optimization of the model during formal training can be better focused on how toextract the features of the diseased area, and the utilization rate of the data is greatly improved.

The invention relates to a DCNN (Deep Convolutional Neural Network)-DNN (Deep Neural Network) and PV-SVM (Paragraph Vector-Support Vector Machine)-based multi-modal depressive disorder estimation and classification method. The method comprises the following steps: preprocessing audio and video features through a displacement range histogram and an Opensmile tool, extracting hidden layer abstract features of audio and video statistical features through a DCNN, performing depressive disorder estimation through a DNN, performing high-dimensional feature mapping on textile information through a PV method, inputting an obtained high-dimensional feature expression into an SVM for binary classification, connecting a depressive disorder estimation result with a binary classification result in series, inputting the whole into a random forests model for training, and performing a final depressive disorder classification task through the trained random forests model, namely judging a depressive disorder or a non depressive disorder. By the adoption of a DCNN model for extraction of the hidden layer abstract features from a primary audio/video, an original high-dimensional feature is more compact, and included information is richer; therefore, the model is more effective, and the phenomenon of overfitting caused by extremely high dimension of the feature is avoided.

The invention discloses application of demethylation modification of targeted mRNA by using PspCas13b in combination with m6A demethylase Alkbh5. A study shows that a PspCas13b-Alkbh5 fusion protein can perform demethylation modification by targeting target gene (such as CYB5A and CTNNB1) mRNA through the specific gRNA to further regulate the target gene expression. m6A RNA immunoprecipitation assays and m6A site quantitative PCR results show that the PspCas13b-Alkbh5 fusion protein can effectively reduce the m6A methylation level of the target gene mRNA in the cell, and no off-target phenomenon is found. The PspCas13b is used as a means and combined with the m6A demethylase Alkbh5 to achieve the demethylation modification of the targeted mRNA for the first time and regulate the expressionof the specific purpose and application accordingly. The method breaks through the previous specific protein expression regulation based on previous change of DNA genetic information, provides a newpotential treatment mode and strategy for treatment of various diseases in the future, and has a good application prospect.

The invention discloses a conjugate, which includes a mutant syphilis detection antigen and a marker. Through gene mutation of the syphilis detection antigen, one or more lysine in the middle of the syphilis detection antigen can be mutated. The lysine easy to combine with the marker in the middle of the syphilis detection antigen turns into other amino acids, so that the marker is marked at a lysine site at the N terminal or C terminal of the mutant syphilis detection antigen and does not combine with the middle part amino acid, thus avoiding wrapping of the antigen active site by the marker. Compared with traditional reagents, the antigen active site of the conjugate is not wrapped by the marker, the antigenic activity decrease caused by combination of antigen determinants and the marker can be avoided, thereby not affecting the antigen activity. The conjugate can improve the detection sensitivity and specificity when used for syphilis detection, and can avoid the prozone phenomenon. The invention also discloses the preparation method and application of the conjugate.
