人脐血间充质干细胞移植联合神经节苷脂注射治疗脑性瘫痪

BACKGROUND:In recent years, some studies have demonstrated that ganglioside can promote survival and differentiation of umbilical blood cord mesenchymal stem cells in vitro. OBJECTIVE:To observe the effect of injection of human umbilical blood cord mesenchymal stem cells and ganglioside into rat lateral ventricles on neurological functional recovery from cerebral palsy. METHODS:Totally 60 cerebral palsy neonatal rats were delivered from pregnant rats which were modes were given intraperitoneal injection of lipopolysaccharide for 2 successive days on day 17 of gestation. Then those neonatal rats were randomly divided into five groups, including model group (n=10), sham transplantation group (n=10), stem cell transplantation group (n=18), ganglioside group (n=10) and combination group (n=12). Under stereotaxic instrument, umbilical blood cord mesenchymal stem cells or ganglioside were injected into left lateral ventricles of the rat brain, respectively, and the sham transplantation group was given the same volume of phosphate buffered saline. Two rats from the stem cell transplantation group were put to death for immunofluorescence staining at 7, 14, 21 and 28 days after transplantation, respectively, and two rats in the combination group were killed for immunofluorescence staining at 14 days. Besides, all rats were underwent neurologic evaluation at 28 days after transplantation. RESULTS AND CONCLUSION:The umbilical blood cord mesenchymal stem cells could survive, migrate and differentiate, which mainly distributed in the lateral ventricle, hippocampus and cortex. At 14 days after transplantation, positive expressions of BrdU and glial fibrillary acidic protein in the combination group were significantly higher than those in the stem cell transplantation group (P < 0.05). In addition, compared with the model group, the holding time significantly prolonged and foot error times significantly decreased in the latter three groups (P < 0.05), as well as in the combination group compared with the stem cell transplantation and ganglioside groups (P < 0.05). These results indicate that umbilical blood cord mesenchymal stem cells and ganglioside can both improve neurological function of rats with cerebral palsy. Given that ganglioside can promote survival and differentiation of umbilical blood cord mesenchymal stem cells in vivo, the combined transplantation is preferred.     

人脐血间充质干细胞在脑瘫大鼠脑内定植和存活能力的研究

目的:通过侧脑室注射,观察人脐血间充质干细胞（MRCs）在脑瘫（CP）大鼠脑内的存活、迁移、分化情况。方法:用腹腔注射脂多糖方法制作CP大鼠模型14只,将标记过的MSCs经侧脑室注射到12只CP大鼠脑内,观察在注射1～4周后MSCs在脑内存活、迁移、分化情况;2只不进行注射的CP大鼠作空白对照。结果:腹腔注射脂多糖方法成功制作CP模型;MSCs鉴定成功;MSCs经侧脑室注射能在CP大鼠脑内存活、迁移,并分化成神经细胞,随移植时间推移,有减少趋势（P<0.01）。2只未注射模型大鼠未检测到MSCs阳性细胞。结论:MSCs能在CP大鼠脑内定植,随着时间推移,数量明显减少。     

婴幼儿感染性疾病患者血清皮质醇浓度的观察

皮质醇是人肾上腺皮质分泌的主要激素之一,也是最主要的糖皮质激素,它的含量占血中17羟类固醇总量的五分之四。具有抗炎抗过敏和抗毒作用。国内外有关婴幼儿感染性疾病患者血清皮质醇浓度报道不多,为此,我们进行了探讨,现将结果报道如下。
