Effects of human umbilical cord mesenchymal stem cells transplantation on treating hypoxic-ischemic encephalopathy / 中国综合临床

ABSTRACT

Objective To investigate the effects of human umbilical cord mesenchymal stem cells (hUCMSCs)transplantation on the treatment of hypoxic-ischemic encephalopathy(HIE). Methods A total of 25 HIE patients were randomly divided into stem cell transplantation group(15 case)and control group(10 cases). The patients in transplantation group were given intravenous infusion of hUCMSCs,which isolated under sterile condition in vitro and cultured, while in control group were treated with routine drug treatment. Neurological function( American National Institutes of Health Stroke Scale( NIHSS ),Barthel index (BI)),extrapyramidal function(Unified Parkinson's disease questionnaire(UPDRS)),cognition and emotional reaction(The mini mental state examination(MMSE),the 14 item Hamilton Depression Scale(HAMD14)and HAMD24)were all assessed before and after transplantation for 14 d,90 d and 180 d respectively to evaluate the clinical efficacy of hUCMSCs transplantation. Results There was no significant difference between two groups in terms of each function before transplantation. The scores of transplantation group were all obviously improved after treatment for 14 d,90 d and 180 d compared to that of before treatment,and the therapy effect in transplantation group was significantly better than that of the control group( NIHSSFtime =4. 372,P=0. 031;Ftime*group =4. 175,P=0. 038;Fgroup =3. 897,P=0. 045.BIFtime =4. 728,P=0. 044;Ftime*group =4. 894,P=0. 037;Fgroup =4. 284,P=0. 039.UPDRSFtime =5. 112,P=0. 047;Ftime*group =4. 895,P=0. 045;Fgroup=3. 879,P =0. 031.MMSEFtime =5. 135,P =0. 039;Ftime*group =3. 213,P =0. 036;Fgroup =4. 184,P=0. 045.HAMD14Ftime =3. 977,P =0. 049;Ftime*group =4. 587,P =0. 038;Fgroup =4. 381,P =0. 041.HAMD24Ftime =3. 845,P =0. 033;Ftime*group =4. 125,P=0. 035;Fgroup =3. 547,P=0. 034). Conclusion Transplantation of hUCMSCs is safe and effective for treatment of HIE,which can significantly improve the neurological function,extrapyramidal function,cognition and emotion.
