Clinicians can use VR devices to access a first-person perspective and accurately perform remote auscultation, bedside ultrasound, medical record and monitoring data review and other operations. This not only reduces infection risks and eases the heavy workload of medical staff, but also ensures timely treatment for critically ill patients, helping hospitals and grassroots cooperative institutions deliver standardized critical care.

According to statistics from the Particle Therapy Co‑Operative Group (PTCOG), by 2021, more than 260,000 patients worldwide had received proton or heavy‑ion therapy. The number of proton centers grew from 1 in 1990 to over 100 today, and is still rising rapidly. Proton therapy has become a major global trend in precision cancer radiotherapy.

Rectal cancer care is now defined by precision, individualization and function priority: 1.Precision evaluation: MRI and CT for accurate tumor mapping 2.MDT collaboration: colorectal surgery, radiotherapy, oncology, radiology 3.Technical innovation: robotic surgery, neoadjuvant therapy, Cai’s Stent, Parks procedure 4.Patient‑centered: tailored to age, function needs and economic status
