| 1 | 老年2型糖尿病与骨质疏松的相关因素显示文摘目的探讨老年2型糖尿病(T2DM)合并骨质疏松的相关因素。方法选择120例老年T2DM患者及136例为对照组,测量其骨密度(BMD)值,采用病例对照法分析老年T2DM组中两个亚组与对照组相关指标。使用Logistic回归分析T2DM患者各种与骨质疏松相关的危险因素。结果 T2DM组患者骨质疏松发病率82.5%,对照组为12.6%。两组相比BMD偏低(P<0.01)。糖尿病患者的BMD与年龄、糖尿病病程、糖化血红蛋白(HbA1c)、女性绝经年限和甲状旁腺激素(PTH)呈负相关,与空腹胰岛素(FINS)、体重指数(BMI)、降钙素(CT)呈正相关(P<0.05)。结论影响老年T2DM患者BMD的因素有年龄、病程、BMI、FINS水平、HbA1c、女性绝经年限。T2DM患者骨量改变与PTH、CT等钙调节激素的变化有关。 | 缪琪蕾 莫丽亚 王敏红 吴永华 | 2014 | 中国老年学杂志2014，34，17： | 19 |
| 2 | Clinical therapeutic strategies for early stage of diabetic kidney disease显示文摘Diabetic kidney disease(DKD) is the most common cause of chronic kidney disease, leading to end-stage renal disease and cardiovascular disease. The overall number of patients with DKD will continue to increase in parallel with the increasing global pandemic of type 2 diabetes. Based on landmark clinical trials, DKD has become preventable by controlling conventional factors, including hyperglycemia and hypertension, with multifactorial therapy; however, the remaining risk of DKD progression is still high. In this review, we show the importance of targeting remission/regression of microalbuminuria in type 2 diabetic patients, which may protect against the progression of DKD and cardiovascular events. To achieve remission/regression of microalbuminuria, several steps are important, including the early detection of microalbuminuria with continuousscreening, targeting HbA1c < 7.0% for glucose control, the use of renin angiotensin system inhibitors to control blood pressure, the use of statins or fibrates to control dyslipidemia, and multifactorial treatment. Reducing microalbuminuria is therefore an important therapeutic goal, and the absence of microalbuminuria could be a pivotal biomarker of therapeutic success in diabetic patients. Other therapies, including vitamin D receptor activation, uric acid-lowering drugs, and incretin-related drugs, may also be promising for the prevention of DKD progression. | Munehiro Kitada Keizo Kanasaki Daisuke Koya | 2014 | World Journal of Diabetes2014，5，3： | 12 |
| 3 | Insulin producing cells established using non-integrated lentiviral vector harboring PDX1 gene显示文摘AIM: To investigate reprogramming of human adipose tissue derived stem cells into insulin producing cells using non-integrated lentivirus harboring PDX1 gene.METHODS: In this study, human adipose tissue derived stem cells(hADSCs) were obtained from abdominal adipose tissues by liposuction, selected by plastic adhesion, and characterized by flow cytometric analysis.Human ADSCs were differentiated into adipocytes and osteocytes using differentiating medium to confirm their multipotency. Non-integrated lentiviruses harboring PDX1(Non-integrated LV-PDX1) were constructed using specific plasmids(pLV-HELP, pMD2G, LV-105-PDX1-1).Then, hADSCs were transduced with non-integrated LVPDX1. After transduction, ADSCsPDX1+were cultured in high glucose DMEM medium supplement by B27, nicotinamide and βFGF for 21 d. Expressions of PDX1 andinsulin were detected at protein level by immunofluorescence analysis. Expressions of PDX1, neurogenin3(Ngn3), glucagon, glucose transporter2(Glut2) and somatostatin as specific marker genes were investigated at mRNA level by quantitative RT-PCR. Insulin secretion of hADSCsPDX1+in the high-glucose medium was detected by electrochemiluminescence test. Human ADSCsPDX1+were implanted into hyperglycemic rats.RESULTS: Human ADSCs exhibited their fibroblast-like morphology and made colonies after 7-10 d of culture.Determination of hADSCs identified by FACS analysis showed that hADSCs were positive for mesenchymal cell markers and negative for hematopoietic cell markers that guaranteed the lack of hematopoietic contamination. In vitro differentiation of hADSCs into osteocytes and adipocytes were detected by Alizarin red and Oil red O staining and confirmed their multilineage differentiation ability. Transduced hADSCs+PDX1became round and clusters in the differentiation medium. The appropriate expression of PDX1 and insulin proteins was confirmed using immunocytochemistry analysis.Significant expressions of PDX1, Ngn3, glucagon, Glut2and somatostatin were detected by quantitative RTPCR. hADSCsPDX1+revealed the glucose sensing ability by expressing Glut2 when they were cultured in the medium containing high glucose concentration. The insulin secretion of hADSCsPDX1+in the high glucose medium was 2.32 μU/mL. hADSCsPDX1+implantation into hyperglycemic rats cured it two days after injection by reducing blood glucose levels from 485 mg/dL to the normal level.CONCLUSION: Human ADSCs can differentiate into IPCs by non-integrated LV-PDX1 transduction and have the potential to be used as a resource in type 1 diabetes cell therapy. | Zahra Niki Boroujeni Ahmad Aleyasin | 2013 | World Journal of Stem Cells2013，5，4： | 3 |
