1.The association of ND-1 gene point mutations of mit ochondrial DNA with type 2 diabetes mellitus
Chinese Journal of Endocrinology and Metabolism 1985;0(01):-
In type 2 diabetic patients the f re quencies of point mutations 3316G→A and 3394T→C in mitochondrial DNA (mt DNA) were 3.9% (6/152) and 5.3% (8/152) respectively, which were significantly higher than those in normal controls and patients with coronary heart disease. This fi nding suggests that mtDNA 3316G→A and 3394T→G mutations are related to type 2 diabetes.

0.05).Conclusions:The incidence of CIN and especially high-grade CIN are higher in patients with positive high risk types of HPV-DNA than negative. HPV-DNA testing has significance in the diagnosis of cervical displasia;HPVDNA testing combined with pap smear and colposcopy can increase the diagnosis of cervical diaplasia.

Objective To investigate the differentiation from human mesenchymal stem cells (hMSC) into neuron-like cells. Methods hMSC were separated from rib marrow with Ficoll-Paque reagent and expanded in culture medium. hMSC were induced to differentiate into neurons with DMEM/BHA/DMSO or DMEM/monothioglycerol, respectively. Neuron-specific enolase (NSE), neurofilament (NF), nestin, glial fibrillary acidic protein (GFAP) were detected by immunohistochemistry. Results hMSC were expanded to be undifferentiated cells in culture for more than 10 passages. The isolated and cultured MSC comprised a single phenotypic population and displayed a fibroblast-like morphology. Simple method induced hMSC exhibiting a neuronal phenotype, with a positive expression of NSE, NF-M and nestin at 5 hours. But the neuron-like cells did not express the glial astrocyte marker GFAP. Conclusion It suggests that hMSC can be differentiated into neurons in vitro .

Objective To observe therapeutic effects of treating stroke hemiplegia with acupuncture combined with rehabilitation training. Methods 72 patients with stroke hemiplegia were randomly recruited into a control group and a treatment group, with 36 patients in each group. The treatment group was treated with acupuncture combined with rehabilitation training and the control group was treated with acupuncture exclusively. Both scalp acupuncture and body acupuncture were used in the process of treatment. Results There was statistical significance (P<0.01) between the two groups in functional rehabilitation of limbs and ADL score (P<0.01) . Conclusion The treatment of stroke hemiplegia with acupuncture combined with rehabilitation training is more effective than that of treating with acupuncture exclusively.

Objective To observe the effect of advanced glycosylation end products(AGEs) on gene expression of connective tissue growth factor(CTGF) in NIH Swiss mouse embryo fibroblasts(NIH/3T3),and to assess the intervention actions of aminoguanidine(AG) and puerarin(Pue) on CTGF mRNA expression in NIH/3T3.Methods AGEs were synthesized by coincubation of BSA with glucose.The AGEs content was measured by fluorescence spectroscopy.NIH/3T3 cells were treated with AGEs(prepared with 20,50,80 mmol?L-1 glucose) for 24 h.The NIH/3T3 cells were treated with AGEs(prepared with 50 mmol?L-1 glucose) for 0,6,12,24 and 48 h.The intervention actions of AG and Pue with different concentration(0.25,0.5,1.0 and 1.5 g?L-1) were evaluated.The CTGF mRNA expression in NIH/3T3 was determined by RT-PCR.Results Compared with BSA control,the CTGF mRNA expression levels in NIH/3T3 were increased by treatment with AGEs(prepared with 20,50,80 mmol?L-1 glucose) for 24 h(P

Objective To study the effects of puerarin on advanced glycation end products (AGEs) and expression of monocyte chemoattractant protein-1 (MCP-1) in diabetic rats. Methods The rats were randomly divided into normal control rats (CON rats), diabetic rats (DM rats), diabetic rats treated with aminoguanidine (AG rats), and diabetic rats treated with puerarin (PU rats). The diabetic rat model was induced by streptozotocin. The serum levels of AGEs and MCP-1 were quantified by fluorescence spectroscopy and ELISA respectively. Tissue sections with PAS staining and electronic microscopy were used for observation of the pathologic changes in renal tissues. Immunohistochemistry was applied to detect the expression of MCP-1 protein in renal cortex. Results Serum levels of AGEs and MCP-1 in DM rats were higher than those in PU rats and AG rats (both P

Objective To study the effects of static magnetic field (SMF) on development of rat embryonic spinal cord neurons. Methods Primary cultured embryonic spinal cord neurons of Wistar rat were exposed to 1.0, 10.0, 50.0, 100.0 and 200.0 mT static magnetic field. The morphological structure, cell's differentiation and proliferation of the embryonic spinal cord neurons were observed and the contents of MDA, superoxide dismutase (SOD) and protein contents in the neurons were determined. Results Static magnetic field at density of 50-200.0 mT could inhibit the differentiation and proliferation of the cells and the phenomena such as cell aggregation, detouchment of some cells, decrease of clone-formation rate and the size of the cells were observed. The contents of MDA in the cells were increased, while the activities of SOD and the level of protein were decreased. Conclusion Static magnetic field might damage the development of embryonic spinal cord neurons by enhancing the lipid peroxidation.
