They retain the capacity to multiply in response to stimuli. Chances of regeneration remain Including: parenchymal cells of organs like liver, pancreas，kidneys, adrenal and thyroid; mesenchymal cells like, fibroblasts and endothelium. ;They are non-dividing cells which have left the cell cycle and die after injury. Including: neurons, skeletal muscle and cardiac muscle cells The peripheral nerve has retained the capacity for regeneration with damage. ; ???????????????????????????????????????????????????;Regenerative process of tissues;Regeneration of Epithelial Tissues;Regeneration of gastric epithelium mucosa in peptic ulcer; Partial resection---restoration quickly and completely Extensive necrosis with intact stromal network, --- restore the normal structure Extensive necrosis accompanied by stromal tissues network destroy---hard to restore;Repair of the injury ;Spotty necrosis--The hepatocyte necrosis limited to scattered cells within hepatic lobules.;Submassive necrosis --The hepatocyte necrosis is extensive with tissues framework destroy; Glandular epithelial cells regeneration—liver ;Regeneration of Connective tissue;Proliferation of Blood Vessels --Angiogenesis;Proliferation of Blood Vessels--Angiogenesis;Regeneration of muscular tissues ;;Regeneration of nerve tissue;Regeneration of nerve tissue;Influential factor on cell regeneration;Stem cells;Self-renewal and differentiation of stem cells;Repair of the injury ;Dancing of life;患者男，37岁，以“规律性上腹痛二年，加重一周”为主诉入院。查体：上腹部剑突下偏左有压痛。胃镜检查提示“胃窦部溃疡”。经给予甲氰咪胍等制酸剂和氢氧化铝凝胶等胃粘膜保护剂治疗，症状逐渐缓解，6周后复查胃镜见溃疡已愈合。;第三节 纤维性修复 Section 3 Fibrous repair ; by removal of the inflammatory ex
