  • ADVANCE IN DIFFERENTIATION OF EMBRYONIC STEM CELLS INTO OSTEOBLASTS IN VITRO

    Objective To review the progress, methods and obstacles in the differentiation of embryonic stem cells(ESCs) into osteoblasts in vitro. Methods The recent literature concerned with the differentiation of ESCs into the osteoblasts was extensively reviewed and briefly summarized. Results ESCs was a good tool for derivation of obsteoblasts.Conclusion The study on the induction of ESCsinto the osteogenic lineage provides a model for analyzing the molecular processes of osteoblasts development in vivo and establishes the foundation for the use of ESCs in skeletal tissue repair. 

  • REPAIR OF LARGE ABDOMINAL WALL DEFECT WITH PEDICLE GRAFT OF GREATER OMENTUM AND POLYPROPYLENE MESH

    Objective To evaluate the outcome of pedicle graft of greater omentum and polypropylene mesh in reconstruction of large defect of abdominal wall caused by surgical incision. Methods From 1994 to 2004, 12 cases of large abdominal wall defects were repaired with pedicle graft of greater omentum and polypropylene mesh after removal of abdominal wall tumor; the defect sizes of abdominal wall ranged from 10 cm×7 cm to 25 cm×17 cm. Results The abdominal wall wound in 12 cases were healed by first intention. After a follow-up of 1 to 5 years, no complications of abdominal hernia, infection and intestine obstruction occurred in all patients. Conclusion It is reliable to repair abdominal wall defect caused by surgical incision with pedicle graft of greater omentum and polypropylene mesh instead of peritoneum.

  • 纳米炭染色结直肠癌淋巴结分站对比研究

    目的探究纳米炭染色对结直肠癌淋巴结示踪的规律以及对转移淋巴结检出的影响。方法回顾性收集2022年4月至2023年9月期间于重庆医科大学附属第一医院胃肠外科接受腹腔镜结直肠癌根治性手术及术前行肿瘤纳米炭标记的92例患者的标本。新鲜标本淋巴结按第一站、第二站及第三站分检,各站又分为染色组和未染色组。比较各组间及组内不同站不同染色程度淋巴结的差异。结果共纳入92例患者,共分检出淋巴结2 859枚,其中转移淋巴结66枚(2.3%),未转移2 793枚(97.7%);黑染淋巴结2 167枚(75.8%),未染色692枚(24.2%)。淋巴结染色率从第一到第三站逐渐递增(P<0.017);第一站和第二站转移淋巴结的染色率比同站所有淋巴结染色率低(χ2=23.959,P<0.001;χ2=7.187,P=0.007),但在第三站中差异无统计学意义(χ2=1.155,P=0.283);第一站和第二站染色淋巴结转移率小于未染色淋巴结(χ2=26.224,P<0.001;χ2=7.520,P=0.006),但第三站中差异无统计学意义(χ2=1.232,P=0.267)。结论纳米炭淋巴结示踪效果随着淋巴回流逐渐增强。在第一站和第二站,其对于转移淋巴结的显示缺乏特异性,手术及分检过程中应更关注未染色淋巴结。在第三站淋巴结中,能够更有效地示踪转移淋巴结,可按染色淋巴结进行针对性地淋巴结清扫。
