分享背景：随着人口老龄化的不断加剧和生活水平的不断提高，心脑血管疾病、肿瘤等具有典型老龄化特征的患者人群迅猛增长。例如，我国各类心脑血管疾病患者总数超过亿。庞大的患者人群给临床治疗与健康生活保障带来巨大压力，成为目前重大的国计民生问题。

血管介入手术是治疗心脑血管最有效的方式。但是纯人工手术存在诸多问题，需要临床医师具备丰富的临床经验、高超的手术技能、及良好的生理心理素质，因此，技术精湛的医生成为稀缺资源。借助机器人辅助医生实施介入手术，能有效降低手术难度、提高手术精度。鉴于此，立足于当前人工智能与先进机器人技术的发展，开展了智能化精准血管介入手术研究。包括：

开发了具有多器械协同递送功能的血管介入手术机器人系统，并对其进行精准控制。根据同时协同递送不少于2种器械的临床需求，通过梳理分析各类手术器械的输送时序与特点，结合医生操作需求与仿生学原理，设计了新一代血管介入手术机器人，并成功完成了多中心多例临床试验。

分享背景：Lung cancer has the highest incidence and mortality rates among all cancer types in the world. The mutation of a protein called the epidermal growth factor receptor (EGFR) is a major cause of non-small cell lung cancer (NSCLC). Anti-EGFR tyrosine kinase inhibitors (TKIs) can work effectively initially, which reduce tumor size and increase the patient survival time. However, almost all patients develop drug resistance after about a year of treatment due to one or more additional mutations of EGFR.

In collaboration with medical doctors, our research group has studied EGFR mutations at the molecular and atomic levels. We have collected EGFR mutations from the literature and from clinical cases at Queen Mary Hospital. Some of the mutations observed locally are rare and have never been reported in scientific journals before. Based on computational models, we analyzed how the 3D structure of EGFR will change due to a mutation. Then for each drug, we computed its binding strength with EGFR before and after the secondary mutation. The reduction in the binding strength reflects the degradation of the drug effectiveness. We have built and published a 3D structural database of EGFR mutants. We have analyzed the characteristics of all known EGFR mutations.

Biomolecular surface complementarity is important in protein-drug interactions. We can find EGFR surface atoms using the alpha-shape model. The solid angles at these atoms represent the surface curvature, which is used as a geometric property in our analysis. Concave shapes around the binding sites are more likely to offer opportunities for drug binding than convex shapes. If the drug binds to EGFR mutants very tightly, then it will strengthen the response. We have studied the EGFR mutation-induced drug resistance by analyzing the solid angles around the binding sites. We have introduced the concept of eigen-binding surface to investigate common properties of biomolecular surfaces that are significant in protein-drug complexes.

EGFR is a member of the ErbB family. A pair of this family members can form a dimer to perform various biological functions. We have investigated the EGFR (ErbB-1) and ErbB-3 heterodimerization, regarded as the origin of intracellular signaling pathways. We combined the molecular interaction in EGFR heterodimerization with that between the EGFR tyrosine kinase and its inhibitor. For 168 clinical subjects, we characterized their corresponding EGFR mutations using molecular interactions, with three potential dimerization partners (ErbB-2, IGF-1R and c-Met) of EGFR and two of its small molecule inhibitors (gefitinib and erlotinib). Based on molecular dynamics simulations and structural analysis, we modeled these mutant-partner or mutant-inhibitor interactions using the binding free energy and its components.

Our work leads to a deeper understanding of the mechanisms of cancer drug resistance. The knowledge gained can help the design of new and more effective drugs. The databases and computer algorithms developed provide a useful reference to medical doctors for assessment of drug resistance level for different EGFR mutants and for planning personalized treatment of lung cancer patients.
