Corrosion inhibitors for steel, such as sodium phosphate （Na3PO4）, sodium nitrite （NaNO2）, and benzotriazole （BTA）, in simulated concrete pore solutions （saturated Ca（OH）2） were investigated. Corrosion behaviors of steel in different solutions were studied by means of corrosion potential （Ecorr）, linear polarization resistance （LPR）, electrochemical impedance spectroscopy （EIS）, and potentiodynamic polarization （PDP）. A field emission scanning electron microscope （FESEM） equipped with energy dispersive X-ray analysis （EDXA） was used for observing the microstructures and morphology of corrosion products of steel. The results indicate that, compared with the commonly used nitrite-based inhibitors, Na3PO4 is not a good inhibitor, while BTA may be a potentially effective inhibitor to prevent steel from corrosion in simulated concrete pore solutions.

Electrochemical impedance spectroscopy, cyclic potentiodynamic polarization measurements, and scanning electron microscopy in conjunction with energy-dispersive X-ray spectroscopy were used to investigate the influence of mill scale and rust layer on the passivation capability and chloride-induced corrosion behaviors of conventional low-carbon（LC） steel and low-alloy（LA） steel in simulated concrete pore solution. The results show that mill scale exerts different influences on the corrosion resistance of both steels at various electrochemical stages. We propose that the high long-term corrosion resistance of LA steel is mainly achieved through the synergistic effect of a gradually formed compact, adherent and well-distributed Cr-enriched inner rust layer and the physical barrier protection effect of mill scale.

Comprehensive Summary A general and convenient photoredox-catalyzed acylation and alkylcyanation of MBH acetates has been established,enabling the assembly of the C(sp2)–C(sp3)bond by a nitrogen-centered radical strategy for the synthesis of trisubstituted alkenes in moderate to excellent chemical yields(48 examples in total).The reaction of MBH acetates with acyl(indanone)oxime esters afforded trisubstituted alkenes containing 1,4-dicarbonyl ***,the use of Eosin Y as a photocatalyst in the catalytic system resulted in the formation of distal cyano group-anchored trisubstituted alkenes via deconstructive functionalization of cycloketone oxime ***,these resulting 1,4-dicarbonyl compounds could be applied to late-stage transformations,providing important methods for the synthesis of dihydropyridazin-3(2H)-one.

A highly sensitive method is developed for the determination of trace amounts of some heavy metal ions in aqueous solution based on the classical Belousov-Zhabotinskii （BZ） oscillating chemical system. Introducing of S^2- ion makes the new oscillating system Ce（SO4）2 - KBrO3 - CH2（COOH）2 - Na2S - H2SO4 have to a high sensitivity for some heavy metal ions such as Ag^＋, Pb^2＋, Hg^2＋, Cd^2＋, Cu^2＋and Bi^3＋ with detection limits down to 10^-12 mol·L^- 1

Case-cohort study designs are widely used to reduce the cost of large cohort studies. When several diseases are of interest, we can use the same subcohort. In this paper, we will study the casecohort design of marginal additive hazards model for multiple outcomes by a more efficient version. Instead of analyzing each disease separately, ignoring the additional exposure measurements collected on subjects with other diseases, we propose a new weighted estimating equation approach to improve the efficiency by utilizing as much information collected as possible. The consistency and asymptotic normality of the resulting estimator are established. Simulation studies are conducted to examine the finite sample performance of the proposed estimator, which confirm the efficiency gains.

目的评估经皮室间隔化学消融术(PTSMA)在老年药物难治性梗阻性肥厚型心肌病患者中的有效性和安全性。方法连续收录上海交通大学附属胸科医院2001年4月至2019年1月行PTSMA治疗的梗阻性肥厚型心肌病患者,按照年龄分成青年组(年龄<55岁)和老年组(年龄≥55岁)。通过查阅病历记录患者的一般资料、临床病史、手术情况及住院期间并发症发生情况,以及通过电话或门诊随访所记录患者的生命状态、临床表现和心功能情况,应用Kaplan-Meier法分析两组生存曲线。结果共111例患者纳入本研究,中位年龄为56.0(15.0,82.0)岁,女性共42例(37.8%),其中青年组中位年龄43.5(15.0,54.0)岁,老年组中位年龄为63.0(55.0,82.0)岁。总体消融成功率为68.5%,青年组、老年组分别为66.7%、70.0%。术中无水酒精中位注射量为2.0(1.0,5.0)ml,青年组和老年组分别为2.1(1.0,5.0)ml和2.0(1.0,5.0)ml,两组比较差异无统计学意义(P=0.728)。房室传导阻滞、室性心律失常、低血压为手术常见并发症,2例患者(均≥55岁)因持续高度房室传导阻滞需植入永久起搏器,1例患者(66岁)因术后心室颤动、心原性休克经抢救无效死亡。老年组患者围术期主要不良心血管事件(包括心原性死亡,高度房室传导阻滞需植入永久起搏器,由于心室颤动或室性心动过速引起的心搏骤停复苏等)发生率较青年组高(P=0.060)。111例患者除外1例围术期死亡,对其余110例患者进行了长期随访,随访时间为3~212(35.5±48.5)个月,随访率为86.4%(95/110),全因死亡11例,总死亡率为10.0%(11/110),除外1例因肺部感染死亡,其余10例为肥厚型心肌病相关死亡,包括6例心原性猝死,3例因心房颤动、急性脑梗死致死,1例心力衰竭致死。梗阻性肥厚型心肌病患者PTSMA后1年、5年和10年的总生存率分别为96.9%、93.4%和81.1%。青年组和老年组1年、5年、10年总生存率分别97.7%、97.7%、91.6%和96.2%、89.7%、66.4%(P=0.068)。结论老年梗阻性肥厚型心肌病患者PTSMA的效果与青年患者相当,但手术相关的主要不良心血管事件风险可能增加,术后长期总生存率略低于青年组患者。
