ABSTRACT
OBJECTIVE To investigate the correlation between benign paroxysmal positional vertigo (BPPV) and bone mineral density (BMD) in menopausal women with BPPV.METHODS 50 patients between the ages of 50-80 years old of menopausal women with Idiopathic benign paroxysmal positional vertigo(iBPPV)as case group,and postmenopausal healthy people of same age doing physical examinations in hospital medical examination center were selected as control group.The lumbar spine(L1-L4) and femoral neck were measured respectively using dual energy X-ray absorptiometry and expressed in T value.The case group and the control group were divided into three age groups,and the T values of three age groups were statistically analyzed.RESULTS There was significant correlation between the case group and control group(The t values are-3.68、-5.98 and-3.33,respectively,P＜0.05).Pearson correlation analysis showed that there was a negative correlation between iBPPV and bone mineral density(BMD) (r=-0.496,P＜0.05).CONCLUSION There was a correlation between benign paroxysmal positional vertigo and BMD in menopausal women.The results of this study may be helpful for the diagnosis,treatment,prognosis and precaution of iBPPV.
ABSTRACT
BACKGROUND:A variety of embryonic stem cells induction and differentiation systems have been established so far, while the research that promotes embryonic stem cells to differentiate into hematopoietic stem cells is stil at an initial stage, and the induction efficiency needs to be improved. OBJECTIVE:To active the Wnt/β-catenin signal pathway in mouse embryonic stem cells with exogenous win3a as an inducer, and then to observe whether the activation of this pathway wil promote the directional differentiation of embryonic stem cells into hematopoietic progenitor cells. METHODS:The ES-E14TG2a mouse stem cells were cultured with the exogenous wnt3a (100 μg/L) for 21 days, the content ofβ-catenin was tested by cellimmunofluorescence and western blot, and expression of Wnt downstream target gene was detected by quantitative reverse transcription PCR to determine the activation of Wnt/β-catenin signal pathway. Single-layer adherent culture method was used to induce the directional differentiate of above-mentioned cells into hematopoietic stem cells, and detection of hematopoietic development associated surface marker CD34+/Sca-1+was achieved by flow cytometry;meanwhile, the expression of hematopoietic associated gene was measured by quantitative reverse transcription PCR. RESULTS AND CONCLUSION:We found thatβ-catenin accumulated in ES-E14TG2a mouse stem cells after cultured with wnt3a (100 μg/L) for 21 days;the expressions of Wnt downstream target genes such as Pitx2, Frizzled, Sox17 and Oct4 showed the different degrees in increase, meaning the activation of Wnt/β-catenin signal pathway. Furthermore, during the time that we used single-layer adherent culture method to induce hematopoietic stem cells, the CD34+/Sca-1+cells accounted for 20.2%of total cells at day 14, and control cells only accounted for 11.9%. Again, expression quantity of hematopoietic associated gene BMP4, FLK2 and CD34 increased while Smad5 was suppressed significantly. Our data suggest that sustaining action by wnt3a wil active Wnt/β-catenin signal pathway, and also promote the directional differentiation of ES-E14TG2a mouse stem cells into hematopoietic progenitor cells.
ABSTRACT
Objective To understand treatment outcomes of patients diagnosed with type 2 diabetes aged over 30 years in Jiangninglu Neighborhood of downtown Shanghai. Methods Total 642 patients diagnosed as type 2 diabetes aged over 30 were investigated by cluster sampling in Jiangninglu Neighborhood of downtown Shanghai. Status of optimal control of diabetes in them was analyzed based on the recommendations proposed by International Diabetes Federation (IDF) for Western Pacific Region. Results and serum level of glycosylated hemoglobin Alc (HbAlc) of less than 6.5% was achieved in 37.5% (241/were achieved in 23.8% (153/642) and 18.1% (116/642) of them, respectively, and beth systolic and mmol/L was achieved in 21.7% (139/642) of all the participants investigated, triglyceride of less than 1.5 mmol/L in 46.6% (299/642), low-deusity lipoprotein-cholesterol (LDL-C) of less than 2.5 mmol/L in 23.7% (152/642) and high-density lipoprotein-cholesterol of greater than 1.1 mmol/L in 62.1% (399/of their blood glucose, blood pressure and serum LDL-C (defined as HbAlc less than 6.5%, blood pressure less than 130/80 mm Hg and LDL-C less than 2.5 retool/L). Conclusions Only 2.6% of all the patients diagnosed with diabetes aged over 30 in downtown Shanghai get optimal control of their blood glucose, blood pressure and serum lipid, so comprehensive prevention and control for diabetes shall be strengthened for them at community-level of urban areas.
ABSTRACT
One hundred and sixteen cases of vertebral artery type of cervical spondylopathy were treated by electroacupuncture on Fengchi (GB 20) and Jiaji (Ex-B 2, C2-5), cupping plus manipulation of pulling the rotated neck. The result showed 89 cases were cured, 21 cases were improved and 6 cases failed with the total effective rate of 94.8%.
