Tencent Health releases multi-scenario AI product matrix and launches large-scale medical model

On September 8, Tencent Health announced a large medical model and launched multiple AI products such as intelligent question and answer, family doctor assistant, and digital medical imaging platform. Among them, the drug discovery platform "iDrug" released a new protein structure prediction algorithm framework tFold

Tencent Health President Wu Wenda said that the digital upgrade of medical and health has changed from "piloting first" to "fully embracing", and the application of artificial intelligence and various digital tools will accelerate its popularity. Tencent will work with partners to establish the "TRUST" model, strengthen technological innovation and digital infrastructure construction, and promote "digital medical care" to benefit more people

Tencent Health President Wu Wenda: Comprehensively embrace the digital and intelligent upgrade of medical health

Let big models understand medical care better

Zheng Yefeng, an outstanding scientist at Tencent and director of Tencent Tianyan Laboratory, announced the development process of the large medical model. Tencent's newly released full-link self-developed hybrid large model has a parameter scale of over 100 billion and a pre-training corpus of over 2 trillion tokens. It has strong Chinese creation capabilities, logical reasoning capabilities in complex contexts, and reliable task execution. ability. Using this as a base model, we continue to add medical knowledge maps and medical documents covering 2.85 million medical entities, 12.5 million medical relationships, and 98% of medical knowledge, allowing the large model to further master professional medical knowledge. Through multi-task fine-tuning of 30 million question-and-answer dialogues covering patients, doctors, pharmaceutical companies and other scenarios and medical processes, as well as reinforcement learning of 360,000 groups of expert doctor-labeled data, Tencent's large medical model is more professional and accurate in handling medical needs. , while also taking into account patient care and being closer to human doctors.

Tencent Medical’s current large-scale model includes scenarios such as copywriting generation, intelligent question and answer, medical record structuring and retrieval, imaging reporting and auxiliary diagnosis. These large models can be embedded in all aspects of the medical process to improve the level and quality of medical services in application scenarios such as department guidance, doctor recommendation, pre-consultation, doctor-patient dialogue, automatic generation of medical records, and intelligent hospital customer service

Intelligent upgrade of the entire medical treatment process:

Wu Zhigang, general manager of Tencent Health User Platform, introduced that relying on medical knowledge maps and large medical models, AI guidance and diagnosis applications have been comprehensively upgraded, including medical intelligent question and answer, digital human medical assistant, intelligent free consultation, automatic generation of medical records, Applications such as AI rational medication use, intelligent follow-up management, and full-process patient management provide more accurate assistance for the entire medical decision-making process, helping to improve patients' medical experience and the two-way improvement of clinician and pharmacist service efficiency and quality.

In addition to medical intelligent Q&A, the application in the pre-diagnosis stage has also been upgraded with a digital human medical assistant, which can provide 7*24h intelligent customer service and professional science popularization services; during the diagnosis phase, it can learn millions of doctor-patient conversations based on the ability of large models and more than 3,000 disease deductions and analyzes, and upgraded applications such as auxiliary consultation with more realistic simulated free dialogue, automatic generation of medical records that are more in line with writing standards, and auxiliary diagnosis and treatment that can provide interpretable evidence; the post-diagnosis stage uses artificial intelligence and the Internet The new medical model has upgraded applications such as intelligent follow-up management and full-process patient management.

At present, Shanghai Renji Hospital has taken the lead in using Tencent’s medical model to create a highly anthropomorphic virtual digital image “Nurse Xiaowei” with an emphasis on aging-friendly Internet hospital services to provide elderly patients with warmer and more convenient medical care. Serve.

There are many scenarios to promote the popularization of AI applications

In terms of AI-driven drug discovery, Tencent’s “iDrug” platform has the ability to accelerate the discovery of both small molecule drugs and large molecule drugs. According to Tencent AIDD technical leader Liu Wei, in terms of protein structure prediction, the "iDrug" platform has developed a new algorithm framework tFold, and its advanced nature has been proven by international protein structure prediction and evaluation platforms many times; in the field of drug In terms of prediction of ADMET properties, 70 ADMET properties have been developed and put online, and through data training combining physical characteristics and pharmaceutical company cooperation, it has been proven that it can surpass mainstream software; two skeleton transition molecule generation algorithms have been developed to discover nM-level lead compounds, and in It has been effectively proven in 3-4 projects, and reinforcement learning technology has also been introduced to achieve 97% of the generated molecules meeting the requirements in the generation of small drug molecules.

In terms of improving grassroots service capabilities, Tencent Health has released a new family doctor assistant. Wang Qianyi, general manager of Tencent's health strategy and medical products, said that through WeChat and WeChat Enterprise, it opens up communication channels between doctors and patients, and with the support of medical big data models, it provides doctors with smarter contract signing, consultation, follow-up and education capabilities. Based on the capabilities of the medical big data model, the family doctor assistant can become a grassroots AI assistant to provide residents with personalized health management services

Tencent Miying has made a comprehensive upgrade in medical imaging research and application. The platform focuses on cloud application, scientific research and management of digital medical images, and is equipped with artificial intelligence analysis capabilities. It provides integrated medical imaging solutions to support medical institutions, scientific research institutions and scientific and technological innovation enterprises in all aspects of the medical imaging field. In addition, the platform will also open more than 20 Tencent self-developed artificial intelligence engines to help scientific research institutions independently develop and train AI models

Building the “TRUST” model of digital medical care

Currently, Tencent Health Mini Program has connected to more than 3,000 registered public hospitals, more than 5,000 physical examination institutions, and vaccine services in more than 200 cities; medical insurance electronic vouchers cover more than 800,000 designated institutions and more than 20,000 hospitals ; There are more than 600 million electronic health card users through the WeChat channel, and they are connected to more than 5,000 hospitals. Tencent Health further strengthens the connection between users and medical services.

Tencent Health President Wu Wenda said that Tencent Health has been committed to investing in technological innovation and research on medical artificial intelligence-related technologies, and has obtained more than 1,000 patents. At the same time, Tencent’s accumulation of digital infrastructure such as computing power supply, data storage, and security protection will provide reliable underlying support for the medical industry. In addition, through a wide range of user capabilities such as WeChat and Tencent Meetings, artificial intelligence applications can widely contribute to inclusive medical care. Therefore, Tencent Health will further promote the opening up of its own capabilities, technologies and products, work with the industry to establish compliant digital medical standards, and create a replicable innovation model
