Radiotherapy is a crucial component of the treatment of tumors. In addition to directly causing DNA damage in tumor cells and inducing cell apoptosis, radiotherapy is also involved in the regulation of systemic immune status. Increasing evidence indicates that radiotherapy can remodel the tumor immune microenvironment (TIME) and reverse the immunosuppressive state, thereby enhancing anti-tumor effects and demonstrating stronger immune responses and therapeutic benefits when combined with immune checkpoint inhibitors. Taking lung cancer as an example to explore the impacts and potential mechanisms of radiotherapy on the TIME and anti-tumor immunity, which can provide a scientific basis for optimizing the treatment strategies of lung cancer.

Objective To establish the structured electronic medical records system based on XML in hospital. Methods The software system of electronic medical record which is suitable for the practical environment of hospital was developed to establish various types of specialized templates and train the clinicians well. Results The establishment of hospital-wide electronic medical record system has achieved the major goals. Conclusion In the current technical conditions, through process reengineering and software development, the hospital can establish the appropriate electronic medical records system to improve the quality of medical records and efficiency of clinicians.
