Journal of Diabetes Mellitus 2013年第4期3卷 172-183页

the scavenger receptor class B type I (SR-BI) is a high-density lipoprotein (HDL) receptor involved in reverse cholesterol transport. Some studies reported the association to be stronger in the presence of diabetes. the full length gene encoding SR-BI is comprised in 13 exons that are alternatively spliced to produce two major transcripts: the full length SR-BI and the splice variant SR-BII, in which exon 12 is skipped. Considering that type 2 diabetes status is characterized by changes in the concentration of plasma lipids, modifications in lipoprotein size and composition, which may be important modulators of the SR-BI expression;the aims of the study were to examine the influence of SR-BI polymorphism (rs838895) on lipid profile and SR-BI mRNA expression in a population of diabetic patients living in Juana Koslay City. Blood samples were drawn from controls (n = 40) and type 2 diabetic patients (n = 66) and DNA and total RNA were obtained. SR-BI mRNA expression was measured by Rt-PCR and SR-BI polymorphism was detected by tetra Primer ARMSPCR. Compared to controls, diabetic patients had higher fasting serum glucose, glycated hemoglobin, triglycerides, total cholesterol, lowdensity lipoprotein cholesterol, and lower highdensity lipoprotein cholesterol. SR-BI mRNA expression was lower in t2DM when compared to controls, suggesting that the hyperglycemia presents in t2DM patients down-regulates SR-BI mRNA expression. Interestingly, we found that decreased SR-BI expression resulted in markedly increased plasma LDL concentrations in t2DM subjects, and the overexpression of SRBII isoform is responsible for the markedly increased plasma LDL-c concentrations. the polymorphism (rs838895) did not modify the mRNA level of SR-BI in leucocytes from control and diabetic patients. this study provides novel evidence suggesting that hyperglycemia may affect reverse cholesterol transport by controlling SRBI expression in diabetic patients. LDL cholesterol levels are associated with

Objectives: Early identification of patients with the novel coronavirus induced-disease 2019 (COVID-19) and pneumonia is currently challenging. Few data are available on validated scores predictive of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection. The Portuguese Society of Intensive Care (PSIC) proposed a risk score whose main goals were to predict a higher probability of COVID-19 and optimize hospital resources, adjusting patients’ intervention. This study aimed to validate the PSIC risk score applied to inpatients with pneumonia. Methods: A retrospective analysis of 207 patients with pneumonia admitted to a suspected/confirmed SARS-CoV-2 infection specialized ward (20/03 to 20/05/2020) was performed. Score variables were analyzed to determine the significance of the independent predictive variables on the probability of a positive SARS-CoV-2 rRT-PCR test. The binary logistic regression modeling approach was selected. The best cut-off value was obtained with the Receiver Operating Characteristic (ROC) curve together with the evaluation of the discriminatory power through the Area Under the Curve (AUC). Results: The validation cohort included 145 patients. Typical chest computed-tomography features (OR, 12.16;95% tyle="font-family:Verdana;">

目的比较神经网络模型(NNM)与多元线性回归(MLR)预测Ct肺栓塞指数的能力。方法回顾性搜集2015年3月至2016年7月西安交通大学第一附属医院急性肺栓塞患者147例(男79例,女68例),采用随机表法按3∶1分为训练样本和测试样本。所有患者均进行Ct肺动脉成像(CtPA),计算机辅助得到每例患者的栓子总体积(V)、栓子附壁总长度(L)、栓子断面栓塞程度总和(D)及栓子总数(N),人工判读得到Qanadli指数作为Ct肺栓塞指数(Q)。借助SPSS 14.2 Modeler,以Qanadli指数为因变量,Ⅴ、L、D和N为自变量,分别利用MLR和NNM计算Qanadli指数预测值(■)。使用SPSS22.0 Spearman相关分析比较两种模型的Qanadli实际值与预计值的相关性,使用平均绝对误差(MAE)、平均相对误差(MRE)和均方根误差(RMSE)比较两种模型的精确程度。结果MLR方程:■=10.98+1.37×V+0.06×L,模型拟合度为0.764。NNM:隐层1层,隐藏神经元2个,模型准确性0.868。训练样本中,NNM计算得到■与Q的相关系数(r=0.932,Pt=3.402,P=0.002);测试样本中,NNM得到的MAE(6.643)、MRE(0.312)和RMSE(9.195)低于MLR得到的MAE(8.505)、MRE(0.334)和RMSE(10.361),差异具有统计学意义(t=3.383,P=0.001)。结论NNM较MLR能更好地预测急性肺栓塞的Ct肺栓塞指数。

AIM to determine the effect of tempol in normal rats fed high salt on arterial pressure and the balance between antagonist components of the renal renin-angiotensin *** Sprague-Dawley rats were fed with 8% NaCl high-salt （HS） or 0.4% NaCl （normal-salt, NS） diet for 3 wk, with or without tempol （t）（1 mmol/L, administered in drinking water）. Mean arterial pressure （MAP）, glomerular fltration rate （GFR）, and urinary sodium excretion （UVNa） were measured. We evaluated angiotensin Ⅱ （Ang Ⅱ）, angiotensin 1-7 （Ang 1-7）, angiotensin converting enzyme 2 （ACE2）, mas receptor （MasR）, angiotensin type 1 receptor （At1R） and angiotensin type 2 receptor （At2R） in renal tissues by *** intake of high sodium produced a slight but signifcant increase in MAP and differentially regulated components of the renal renin-angiotensin system （RAS）. this included an increase in Ang Ⅱ and At1R, and decrease in ACE-2 staining intensity using immunohistochemistry. Antioxidant supplementation with tempol increased natriuresis and GFR, prevented changes in blood pressure and reversed the imbalance of renal RAS components. this includes a decrease in Ang Ⅱ and At1R, as increase in At2, ACE2, Ang （1-7） and MasR staining intensity using immunohistochemistry. In addition, the natriuretic effects of tempol were observed in NS-t group, which showed an increased staining intensity of At2, ACE2, Ang （1-7） and *** these findings suggest that a high salt diet leads to changes in the homeostasis and balance between opposing components of the renal RAS in hypertension to favour an increase in Ang Ⅱ. Chronic antioxidant supplementation can modulate the balance between the natriuretic and antinatriuretic components of the renal RAS.
