Inappropriate shock of implantable cardioverter defibrillator(ICD)is a rare but catastrophic phenomenon.Inappropriate shock is usually caused by oversensing of noise or supraventricular tachycardias(SVTs).However,inappropriate shock can also be triggered by other uncommon mechanisms.Lead dislodgement is also rare in patients with cardiac implantable electronic devices,which can manifest as pacing failure and mis-sensing of other signals.

A novel porphyrin-Schiff base was synthesized via the condensation of 5-（4-aminophenyl） -10,15,20-triphenylperphyrin and ethyl vanillin. After analyzing the level of purification of the perphyrin-Schiff base, it was successfully separated. This perphyrin-Schiff base was characterized by using UV-Vis, IR,^1H NMR and MS spectroscopy.

AIM:To investigate the prevalence and time of Dickkopf(DKK) family methylation and its clinical significance in hepatocarcinogenesis. METHODS:Methylation of DKK family genes was quantitatively analyzed in 115 liver tissue samples,including 50 pairs of primary hepatocellular carcinoma(HCC) and matched noncancerous cirrhotic tissue samples,as well as 15 liver cirrhosis biopsy samples. RESULTS:The methylation level of DKK3 was significantly higher in HCC tissue samples than in matched noncancerous cirrhotic tissue samples(P1%) was significantly shorter than that of those with a lower DKK3 methylation level(PMR≤1%)(P=0.0255) . Multivariate Cox analysis indicated that methylated DKK3 was significantly and independently related with a shorter survival time(relative risk=2.527,95%CI:1.063-6.008,P=0.036) of HCC patients. CONCLUSION:Methylation of DKK3 is an important event in early malignant transformation and HCC progression,and therefore might be a prognostic indicator for risk assessment of HCC.

许多核分类方法的决策函数可以表示为支持向量的组合,如SVM,而支持向量含有非常重要的隐私信息,因此,在分类决策时可能会暴露此类信息,同时分类速度受限于支持向量的个数,如SVM的分类复杂度为O(|SVs|).为解决上述两个问题,本文基于最小包含球球心在原始空间中的代理原像,提出了一种隐藏支持向量信息并能快速实现分类的SVM方法,称为隐私保护的快速SVM分类方法(Fast Classification Approach of SVM with Privacy Preservation,FCA-SVMWPP).同时提供了两种求解代理球心原像的方法,分别称为QP解法和直接解法.UCI和PIE人脸数据集的实验结果表明,本文方法可解决上述两个问题并具有较好的效果.

本文认为,我国目前对于基本医疗服务价格和大型设备检查/药品价格的分别规制,使得作为代理人的医生/医院行为出现扭曲,医生的努力水平低于次优水平且分配不对称,导致以降低医疗支出为目的的价格规制不仅无助于控制医疗费用的上涨,反而可能作为一种对医院的间接补偿手段产生更大的医疗支出。并且,不对称的努力会为患者带来比只存在医生道德风险和有限责任的次优状态时更大的福利损失,也会降低整个社会的福利。因此,改革的方向,在于改变对不同服务分别规制的现状,实行基于总成本的统一规制。

对待马克思主义,既要避免“思想僵化”,又要避免“立场丧失”。为此,有必要对马克思主义理论的“内核”和“外围”作一个区分。一方面,适当放宽和调整对理论之外围的理解;另一方面,坚守对理论之核心内容的信念,理论的核心内容就是马克思主义有关理论和实践的关系问题、现实和理想的关系问题、个人和社会的关系问题的观点。

“事实”与“规范”的关系既是现代哲学的重要理论问题,也是现代社会的重要实践问题,更确切地说,是一个具有重要的政治—法律含义的哲学问题。从讨论“事实”与“规范”的关系(或“事实性”与“有效性”)的关系入手,德国哲学家哈贝马斯提出了他所谓的“商谈的民主理论”和“程序主义的法律范式”,并设法在这个新的基础上批判资本主义现实、辩护社会主义理想。厘清哈贝马斯的政治—法律理论的复杂论证,研究这个产生于特殊语境的理论的可能的普遍意义,有助于我们思考什么是有中国特色的社会主义法治国家、有中国特色的社会主义协商民主。

本文研究了天然六方磁黄铁矿(HNP,Fe_(0.93)S)与天然单斜磁黄铁矿(MNP,Fe_(0.85)S)活化过硫酸盐(PDS)降解罗丹明B(RhB)的性能差异及其机理。结果表明,在酸性和弱碱性条件下,MNP/PDS体系的降解效率(pH=4时为97.15%)均高于HNP/PDS体系(pH=4时为86.91%),且两个体系的降解效率均随pH的升高而降低。MNP/PDS体系较高的降解效率与体系中较高的溶解铁浓度和MNP表面较强的反应性有关,且后者是主要因素,即降解反应主要发生在磁黄铁矿的表面及近表面处。MNP较强的表面反应性首先体现在其相对较高的Zeta电位,这使得MNP与PDS之间的静电引力更强,PDS更容易被MNP活化。其次,MNP表面具有更高的腐蚀电流密度,这有利于Fe(Ⅱ)对PDS的非均相活化以及表面还原性硫物种(如S^(2-)和S_(2)^(2-))作为电子给体将Fe(Ⅲ)还原为Fe(Ⅱ)(或Fe^(3+)还原为Fe^(2+))。此外,MNP表面的疏松氧化层在降解过程中容易脱落,进而暴露出新的表面活性位点。

Non-liner wave equation inversion,wavelet analysis and artificial neural networks were used to obtain stratum parameters and the distribution of thin coal seams.The lithology of the water-bearing/resisting layer in the Quaternary system was also predicted.The implementation process included calculating the well log parameters,stratum contrasting the seismic data and the well logs,and extracting,studying and predicting seismic attributes.Seismic inversion parameters,including the layer velocity and wave impedance,were calculated and effectively used for prediction and analysis.Prior knowledge and seismic interpretation were used to remedy a dearth of seismic data during the inversion procedure.This enhanced the stability of the inversion method.Non-linear seismic inversion and artificial neural networks were used to interpret coal seismic lithology and to study the water-bearing/resisting layer in the Quaternary system.Interpretation of the 1～2 m thin coal seams,and also of the water-bearing/resisting layer in the Quaternary system,is provided.The upper mining limit can be lifted from 60 m to 45 m.The predictions show that this method can provide reliable data useful for thin coal seam exploitation and for lifting the upper mining limit,which is one of the principles of green mining.

Carboxymethyl chitosan(CMCS)-based hydrogels have antibacterial activity,and have shown the abilities of preventing wound infection,promoting cell proliferation,accelerating collagen deposition,and stimulating hyaluronic acid formation during wound healing.As a hormone produced by the pineal gland in humans and animals,melatonin promotes skin wound healing by regulating the release of inflammatory mediators and accelerating the proliferation and migration of cells,angiogenesis,and collagen deposition.However,the combined effects of CMCS and melatonin on wound healing remain unclear.Injectable CMCS-based hydrogels containing melatonin were prepared,and their healing effects were evaluated using a full-thickness cutaneous wound model in rats.Compared with the control and the hydrogel with no melatonin groups,the melatonin-loaded hydrogel significantly increased the percentage of wound closure,promoted the proliferation of granulation tissue and re-epithelialization,and accelerated collagen deposition.Additionally,the melatonin-loaded hydrogel promoted angiogenesis and vascular endothelial growth factor receptor protein expression and increased the expression of cyclooxygenase-2 and inducible nitric oxide synthase.The melatonin-loaded hydrogel also markedly increased the expression of collagen III,α-smooth muscle actin,and transforming growth factor-β1 proteins and reduced collagen I expression.These results suggest that the melatonin-loaded hydrogel promoted granulation tissue formation and accelerated wound healing by reducing inflammation and promoting angiogenesis and collagen deposition.
