多济敷对面部磨削创面愈合的临床疗效观察

目的：本研究采用多济敷外用于面部皮损磨削术后创面,观察其对创面愈合时间、皮肤色素沉着等的变化。方法：采用区域神经阻滞或局部浸润麻醉,对不同类型的面部皮损34例进行皮肤磨削治疗,术后创面应用多济敷或凡士林纱布作为底层敷料包扎创面,术后换药一次,保留底层敷料。结果：2001年8月至2003年9月间,通过自身对照,34例面部磨削术后采用多济敷治疗组较凡士林纱布组创面愈合时间缩短(P＜0．05),经过6个月至2年的随访,皮肤色素沉着也有明显改善。结论：多济敷有利于缩短面部磨削术后创面愈合时间,改善面部色素沉着,外观满意。     

Differentiation of human epidermal stem cells into fibroblasts induced by TGF-β1 in vitro

Objective To investigate the correlation between human epidermal stem cell (hESCs) and hypertrophic scar or keloid. Methods Improved collagen Ⅳ-coated adhesion methods was used to isolate and culture the epidermal stem cells after neutral protease selectively digested the dermo-epidermal junctions. After the cells were cultured and expanded in vitro, and passage 3 hESCs were induced by different concentrations of TGF-β1 (0.1, 5.0, and 10.0 ng/ml). Morphological fea-tures and identification of these cells were meseasured by HE, Masson, immunohistochemical staining on the days 3 and 7, respectively. Results After induced by TGF-β1 for 3 and 7 days, the morpholo-gy of the epidermal stem cell (hESCs) was changed into fusiform shape, similar to fibroblasts. 70 % ofthe cell which was induced by TGF-β1 were blue stained in the cytoplasm by Masson stain, which is the distinctive method for collagen, suggesting collagen appeared or increased in the cells. The collagen concentrations in supernatants of hESCs were 0.4150±0.0014, 0.3380±0. 0020, and 0.3870±0.0020, much higher than that in control group (0.0780±0.0025) and normal skin fibro-blast group (0.15004±0.0051) (P<0.05). Immunohistochemical staining revealed that positive rates of these cells for anti-vimentin staining were more than (95.00±1.20)% in experiments and (5.70±0.20)% in control group. Conclusion The differentiantion of hESCs induced by TGF-β1 into fibro-blasts indicates that hESCs may play a role in the pathogenesis of hypetrophic scar and keloid.     

腹腔镜辅助下截取带血管蒂回肠段转移阴道成形术

目的 探索在腹腔镜辅助下截取带血管蒂回肠段转移再造阴道的可能性，为临床提供阴道成形术的新方法。方法 应用腹腔镜引导下，配合使用超声刀，通过小切口完成肠系膜分离、回肠段截取、肠端吻合、回肠段下拉转移形成阴道。结果 2002年2月至2006年7月，共为38例需再造阴道患者成功地施行腹腔镜辅助下截取带血管蒂回肠段转移阴道成形术。随访1个月～4年，其中36例移植回肠段成活良好，再造阴道符合生理要求。结论 由于避免了剖腹和以往术式的供区瘢痕，较好地缓解了此类患者巨大的心理压力，腹腔镜下回肠段代阴道是目前较为理想的阴道成形术新方法。     

垂直微创切口皮肤软组织扩张器置入术

皮肤软组织扩张器的应用使烧（创）伤后畸形的整复产生了革命性的变化。既往皮肤软组织扩张器的置入多选用平行于扩张器长轴的切口，这一术式缺点主要在于首次扩张时间晚、周期长、切口张力大及易发生扩张器外露等并发症。2002年5月～2004年5月，我们采用垂直微创切口埋置扩张器140个，效果良好。报告如下。     

超选择动脉栓塞联合外科序贯治疗Ⅰ型神经纤维瘤伴巨大神经纤维瘤临床疗效观察

目的:探究DSA联合外科序贯治疗是否可以作为Ⅰ型神经纤维瘤伴巨大神经纤维瘤的重要治疗策略之一。方法:纳入2017年7月-2021年8月收治的11例神经纤维瘤患者作为研究对象。肿瘤大多位于躯干及四肢,瘤体重量2.5~25 kg。全部患者术前备自体血,瘤体切除术前介入超选择栓塞瘤体滋养动脉及其分支,切除瘤体后将栓塞后的部分瘤体组织制备皮瓣及全厚皮片回植于继发创面。观察患者术后恢复情况及并发症发生情况。结果:11例患者中,9例在瘤体切除术后利用部分瘤体皮肤制备全厚皮片回植于组织缺损区域,2例制备皮瓣回植。其中1例患者回植后全厚皮片少部分坏死,经换药等保守治疗愈合可。随访至今,11例患者术后均无复发,术后肢体外形改善,恢复正常行走等组织功能。结论:超选择栓塞瘤体滋养动脉及其分支联合序贯疗法,在治疗NF-I合并巨大神经纤维瘤中术中失血量小,术后并发症少,患者恢复效果好,可作为该疾病的一种治疗策略。     

脂质体介异的人α-干扰素基因转染人口腔粘膜鳞癌细胞引起的凋亡研究
