OBJECTIVE To observe the effects of cryopreserved olfactory ensheathing cells (OECs) transplantation on axonal regeneration and functional recovery following spinal cord injury in adult rats. METHODS Twenty-four rats were divided into experimental and control groups, each group having 12 rats. The spinal cord injury was established by transecting the(More)
OBJECTIVE To study mRNA expression levels of main hematopoietic growth factors in bone marrow mesenchymal stem cells (BM-MSC), and to compare effect on mRNA expression levels treated by ginseng polysaccharide and ginsenoside. METHODS Relative quantification real-time polymerase chain reaction (RT-PCR) was used to observe mRNA expression levels of IL4,(More)
OBJECTIVE The purpose of this retrospective research was to analyze the trend of hospitalized prevalence in the past 10 years (1998 - 2007) and to estimate resource utilization associated with osteoporotic hip fractures, including hospital length of stay and inpatient costs in Guangzhou, China. METHODS 3449 patients aged 50 years and older, hospitalized(More)
OBJECTIVE To study the effects of Chinese medical recipes for invigorating Shen on rat bone marrow mesenchymal stem cells (BMSCs)-derived preadipocytes' differentiation to osteoblasts. METHODS The BMSCs were cultured using whole bone marrow adherence wall method. The BMSCs were induced to preadipocytes by classic chemical method. The osteogenic(More)
OBJECTIVE To further explore the effect of Jiangu Erxian Pill (JGEXP) on proliferation and cell cycle of human osteoblast on the basis of previous clinical and experimental studies. METHODS Human primary osteoblast were isolated and cultured. The cell proliferation was tested by 3H-thymine incorporation and methyl thiazolyl tetrazolium (MMT) method and(More)
