Type 2 diabetes mellitus(T2DM)is recognized as a heterogeneous and complicated disease that is able to influence individuals at various life stages[1].Apart from traditional predictors such as age,family history of diabetes,body mass index,and so on,ambient air pollution is also shown to increase the risk of T2DM in previous studies.

Vitamin D, a fat-soluble vitamin and endocrine horm one, and it impacts various bone and extra-bone health, such as osteoporosis, diabetes, and cancer. The main circulating form of vitamin D is 25-hydroxyvitamin D [25(OH)D] and it is a useful clinical biomarker of vitamin D status. The Institute of Medicine (IOM) defines as vitamin D deficiency (VDD) when serum 25(OH)D concentration is less than 20 ng/mL⑴.Worldwide, VDD is recognized as a severe public health problem. In 2007, Holick estimated that globally over one billion people suffered from VDD or vitamin D insufficiency (VDI). In China, it has bee n reported that the prevale nee of VDD ranged from 38.8% to 91.2% in different regions.

Expression of protein kinase C isoforms in retinoic acid-induced differentiation of mouse embryonic stem cells into neuron-like cells

Chinese Medical Journal 2007年第18期120卷 1639-1642页

作者： GAO Qian-ying WU Jun-shu wang Zhi-chong GE jian HUANG Dan-ping State Key Laboratory of Ophthalmology Zhongshan OphthalmicCenter Sun Yat-sen University Guangzhou 510060 China

Protein kinases C （PKCs）, a big family including 12 isoenzymes, are divided into three major groups according to the variability of their regulatory domains^1.2 The classical PKCs （cPKC） including PKCα, PKCβI, PKCβ2, and PKC7 need calcium, phosphatidylserine, and diacylglycerol or phorbol esters for full activation. The novel PKCs （nPKC） including PKCδ, PKCε, PKCη, PKCθ, and PKC, do not require calcium for their activation. The third group is the atypical PKCs （aPKC） including PKCζ, PKCλ and PKC~ whose activation depends on phosphatidylserine but not on diacylglycerol, calcium or phorbol esters. The differences in function of specific PKC isoforms are mainly due to their different subcellular localization, activation or inhibition by different stimuli, and transcriptional regulation.

Objective To our knowledge, no definitive conclusion has been reached regarding the relationship between glucocorticoids and hypertension. Here, we aimed to explore the characteristics of glucocorticoids in participants with dysglycemia and hypertension, and to analyze their association with blood pressure *** The participants of this study were from the Henan Rural Cohort study. A total of 1,688 patients 18–79 years of age were included in the matched case control study after application of the inclusion and exclusion criteria. Statistical methods were used to analyze the association between glucocorticoids and various indices of blood pressure, through approaches such as logistic regression analysis, trend tests, linear regression, and restricted cubic *** The study population consisted of 552 patients with dysglycemia and hypertension(32.7%).The patients with co-morbidities had higher levels of serum cortisol(P = 0.009) and deoxycortisol(P <0.001). The adjusted odds ratios(and 95% confidence intervals) for dysglycemia with hypertension were1.55(1.18, 2.04) for the highest tertile of Ln-cortisol compared with the lowest tertile. Additionally, the highest Ln-deoxycortisol levels were associated with increased prevalence of dysglycemia with hypertension by 159%(95% confidence interval: 122%, 207%).Conclusions Serum deoxycortisol was positively correlated with systolic blood pressure, pulse pressure, mean arterial pressure, mean blood pressure, and mean proportional arterial ***(deoxycortisol and cortisol) increase the risk of hypertension in people with dysglycemia, particularly in those with T2 DM.

主动式毫米波成像(AMWI)技术是检测隐藏在衣服下的危险物体的有效方法.但AMWI获取的图像通常很模糊,而且一些隐匿物体的尺寸较小,因此隐匿物品的自动检测和定位仍然是一个具有挑战性的问题.姚家雄等[1]首先使用卷积神经网络(CNNs)结合穷举滑动窗口方法来检测隐藏物体.做了两点改进:(1)使用上下文(背景)信息抑制干扰,(2)使用两步搜索方法代替穷举搜索来降低计算复杂度.首先在垂直方向上使用一个CNN来过滤干扰,得到隐藏物体的垂直位置,然后用另一个CNN来确定水平位置.为了充分利用上下文信息,使用IoG(交集和真值的比)代替IoU(交并比)来定义训练和测试过程中的正负样本.实验结果表明,该方法将计算时间减小到约30%,同时实现更好的检测性能.
