With the rapid development of Internet technology and artificial intelligence, medical e-commerce platforms play an increasingly important role in modern pharmaceutical services. This study proposes a Chinese medical dialogue system model MedAsst based on Large Language Model (LLM) and explores its application in medical e-commerce platform. The model is based on Qwen2-7B, and supervised fine-tuning is performed on 1.47 million medical question and answer data by LoRA method. In this paper, the effectiveness of MedAsst is thoroughly evaluated on a medical multiple-choice test and a customised medical quiz dataset. The experimental results show that MedAsst outperforms other baseline models on the evaluation metrics of BLEU-4, ROUGE-1, ROUGE-2, and ROUGE-L, and in particular demonstrates a significant advantage in medical quizzing ability. Compared with LlaMa-3-8B, Gemma-7B, Mistral-7B, and the unfine-tuned Qwen2-7B model, MedAsst performs well in domain-specific tasks through reasonable fine-tuning strategies, demonstrating the necessity and effectiveness of supervised fine-tuning. The research in this paper not only improves the performance of the model in the Chinese medical Q&A task, but also demonstrates the potential application of large language models in medical e-commerce platforms, which provides strong support for future optimisation and practical application in more complex scenarios. %K 大语言模型， %K 监督微调， %K 医疗电商， %K 医学对话系统
