Can regenerative rehabilitation change diabetic‑foot amputation outcomes? Professor Bi Sheng, chief expert at Jianjia Healthcare, developed an autologous blood‑cell combined PRP implantation technique for in‑situ microvascular regeneration. Instead of only recanalizing large arteries, this therapy builds new perfusion networks in ischemic tissue. Clinical cases show improved wound healing, restored walking capacity and higher limb‑salvage rates for patients.
