骨髓间充质干细胞分化为皮肤附属器细胞的初步实验研究

目的探讨骨髓间充质干细胞(marrowmesenchymalstemcells,MSCs)分化为创面皮肤附属器细胞的可能性,及其参与创面修复的可能机制。方法无菌条件下取Wistar大鼠股骨骨髓细胞,密度梯度离心分离、纯化MSCs,体外培养扩增后,用BrdU标记细胞。另于同种雄性Wistar大鼠背部正中,制备1cm×1cm全厚皮肤缺损创面模型,将BrdU标记的1×106/mlMSCs从阴茎静脉输注,术后第3天与第7天切取创面组织,行BrdU免疫组织化学单染色,以及BrdU和广谱角蛋白免疫组织化学双染色。结果BrdU阳性细胞出现在创面皮下组织、皮脂腺、毛囊和骨髓腔中。免疫组织化学双染色结果显示,皮脂腺和毛囊有BrdU阳性细胞,同时表达广谱角蛋白。结论创面愈合过程中,MSCs归巢并参与创面修复;在实验性全身皮肤缺损创面微环境下,MSCs可分化为皮肤附属器细胞。

冬季老人多瘙痒少用肥皂少热水

冬季，不少老人家的皮肤会出现瘙痒。虽然瘙痒并不是什么“大病”，但会影响他们的正常生活。皮肤瘙痒，自然忍不住用手抓挠，可是抓挠并不能解决根本性的问题，反而会令皮肤出现许多抓痕、血痂、色素沉着、苔藓样变，重者甚至发生皮肤细菌感染。     

还原型谷胱甘肽联合甘草酸二铵对腹部开放伤后海水浸泡犬肝功能损伤的治疗作用

Objective To investigate effect of reduced glutathione and diammonium glycyrrhizinate on the treatment of hepatic damage in experimental dogs following open abdominal injuries coupled with seawater immersion. Methods Twenty-four dogs with open abdominal injuries were randomly divided into 3 groups: the control group (given with simple observation after 1.5 h seawater immersion); the routine treatment group (given routine care and fluid transfusion after 1.5 h seawater immersion) ; the hepatic treatment group (given routine are, fluid transfusion and hepatic treatment as well, after 1.5 h seawater immersion). Each group consisted of 8 dogs. Blood samples were taken at different time points to measure total bilirubin (TB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), prothromin time (PT), endotoxin, tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6), and pathological examination was also made at the same time. Results For the control group, contents of TB, ALT, AST and LDH increased significantly and survival time was less than 24 hours. Contents of TB, ALT, AST and LDH of the routine treatment group also increased significantly, but survival time of all the experimental animals was mere than 24 hours. Reduced glutathione and diammonium glycyrrhizinate could reduce the extent of lesion quite significantly 12～24 hours following open abdominal injuries. Conclusions Reduced glutathione and diammonium glycyrrhizinate seemed to have good effects on the treatment and prevention against hepatic damage induced by trauma coupled with seawater immersion. It could be used as a primary means for the treatment of such kind of hepatic damage.
