In this paper, we aim to explore the applications of machine learning and large language model for analyzing gut microbiota data, particularly attempting to investigate large language model module to intelligently conduct data analysis just through prompts. the data of gut microbiota is from 16S rRNA sequencing result of obese mouse for obesity experimental research, and our primary task focus on identifying differentially expressed genes and uncovering biomarker microbiota associated with obesity. Statistical methods, including diversity analysis and principal component analysis, have been firstly conducted, revealing significant differences between experimental and control groups. then different machine learning algorithms including random forest, SVM-RFE, Lasso, and XGBoost have been selected to discover distinguished genes through feature importance ranking. Several types of microbial genes have been identified by both of the machine learning methods, and these biomarkers exhibit significant abundance changes between groups. Some of them have been confirmed with related research literature, and the remains are worthy of attention for more investigation. Furthermore, we have developed a large language model module named Chat2GM, which is based on the LangChain framework, python Flask, and API of OpenAI's GPT model, particularly for this data analysis task. Upon uploading the original microbiota data, data exploration and analysis can be conducted merely by using prompts. It has been demonstrated to achieve satisfactory performance in completing the aforementioned analysis tasks with precise natural language instructions, indicating that applications powered by large language models with more expertise knowledge have great potential in gut microbiota research field.

Post-traumatic stress disorder (PTSD) can be a debilitating condition and early intervention can be instrumental in preventing patients' suffering. Identifying patients at risk for PTSD is challenging because of the limitations of the available data set, variations in the symptoms of PTSD for different patients, and misdiagnosis due to symptoms being shared with other conditions. In this preliminary study, we explore a small set of structured primary care data extracted from patients' electronic medical records (EMR) from Manitoba, Canada. this data has a small subset of PTSD positive cases, and is used to assess the feasibility of applying machine learning algorithms to diagnose PTSD. We developed three supervised machine learning models, a multilayered perceptron artificial neural network (ANN) model, a support vector machine (SVM), and a random forest classifier (RF) to identify PTSD patients using 890 patients' records. these methods obtained 0.79, 0.78, and 0.83 AUC respectively, which are better than all of the previous work that used EMR data having comparable size as our data. this study is geared towards understanding the primary care standard for PTSD patients in Canada in general and military-veteran population and developing a case definition for PTSD. this initial result demonstrates that an automated PTSD screening tool can be developed based on historical medical data for further study. In our ongoing work, we are exploring the providers' chart notes from the EMR data, which is unstructured text data, to improve the model accuracy and understand the progression of PTSD.
