Translation:
Compound Injury
Refers to damage caused by two or more different injurious factors acting simultaneously or within a short period of time on the human body. This type of injury, due to the叠加 of multiple factors, often triggers systemic pathological reactions and is characterized by complex conditions and higher difficulty in treatment.
(Note: The term "叠加" directly translates to "superposition" in English. For clarity and readability in a medical context, it can be rendered as "cumulative effect" or simply "overlap." Here is an optimized version:)
