1某些过渡金属钌配合物非线性光学性能的从头算和密度泛函理论研究显示文摘实验发现金属钌的某些配合物具有大的非线性光学性能 .我们的理论研究表明金属钌配合物[Ru(NH3 ) 4LDLA]n + (n =2 ,3;LD,LA=吡啶衍生物配体 )的非线性光学性能取决于推电子基团LD 的给电子能力以及拉电子基团LA 的受电子能力 ,LD 和LA 的推拉电子能力越强越有利于提高配合物的二阶非线性光学系数 β,因此带正电荷的LA 能大幅度提高 β值 .虽然增加共轭体系的长度有利于提高 β值 ,但在Ru的配体中 ,吡啶环间或吡啶环与苯环间不一定要保持共面也会有大的β值 .DFT和abinitio方法的计算结果对比表明 ,对于含过渡金属Ru的化合物 ,在HF水平上难以得到满意的结论 ,由从头算有限场方法计算得到的 β值偏小 ,而用TDDFT方法能得到可与实验值符合较好的结果 .林晨升 吴克琛 Snijders Jaap.G 洒荣建 陈锡华 2002化学学报2002,60,4:8
2Percutaneous closure of secundum type atrial septal defects:More than 5-year follow-up显示文摘AIM: To investigate long-term efficacy of two different devices more than five years after percutaneous atrial septal defect(ASD) closure in adults.METHODS: All patients who underwent percutaneous closure of an ASD in the St. Antonius Hospital, Nieuwegein, The Netherlands, between February 1998 and December 2006 were included. Percutaneous closure took place under general anaesthesia and transesophageal echocardiographic moni toring. Transthoracic echocardiography(TTE) was performed 24 h post-procedure to visualize the device position and to look for residual shunting using color Doppler. All complications were registered. All patients were invited for an outpatient visit and contrast TTE more than 5-years after closure. Efficacy was based on the presence of a residual right-to-left shunt(RLS), graded as minimal, moderate or severe. The presence of a residual left-to-right shunt(LRS) was diagnosed using color Doppler, and was not graded. Descriptive statistics were used for patients' characteristics. Univariate analysis was used to identify predictors for residual shunting.RESULTS: In total, 104 patients(mean age 45.5 ± 17.1 years) underwent percutaneous ASD closure using an Amplatzer device(ASO) in 76 patients and a Cardioseal/Starflex device(CS/SF) in 28 patients. The mean follow-up was 6.4 ± 3.4 years. Device migration occurred in 4 patients of whom two cases occurred during the index hospitalization(1 ASO, 1 CS/SF). The other 2 cases of device migration occurred during the first 6 mo of follow-up(2 CS/SF). The recurrent thrombo-embolic event rate was similar in both groups: 0.4% per follow-up year. More than 12 mo post-ASD closure and latest follow-up, new-onset supraventricular tachyarrhythmia's occurred in 3.9% and 0% for the ASO and CS/SF group, respectively. The RLS rate at latest follow-up was 17.4%(minimal 10.9%, moderate 2.2%, severe 4.3%) and 45.5%(minimal 27.3%, moderate 18.2%, severe 0%) for the ASO- and CS/SF groups, respectively. There was no residual LRS in both groups.CONCLUSION: Percutaneous ASD closure has good long-term safety and efficacy profiles. The residual RLS rate seems to be high more than 5 years after closure, especially in the CS/SF. Residual LRS was not observed.Roel JR Snijder Maarten J Suttorp Jurrien M Ten Berg Martijn C Post 2015World Journal of Cardiology2015,7,3:6
3Pulmonary hypertension in hereditary haemorrhagic telangiectasia显示文摘Hereditary haemorrhagic telangiectasia(HHT) is an autosomal dominant inherited disorder characterised by vascular malformations in predominantly the brain,liverand lungs.Pulmonary hypertension(PH) is increasingly recognised as a severe complication of HHT.PH may be categorised into two distinct types in patients with HHT.Post-capillary PH most often results from a high pulmonary blood flow that accompanies the high cardiac output state associated with liver arteriovenous malformations.Less frequently,the HHT-related gene mutations in ENG or ACVRL1 appear to predispose patients with HHT to develop pre-capillary pulmonary arterial hypertension.Differentiation between both forms of PH by right heart catheterisation is essential,since both entities are associated with severe morbidity and mortality with different treatment options.Therefore all HHT patients should be referred to an HHT centre.Veronique MM Vorselaars Sebastiaan Velthuis Repke J Snijder Jan Albert Vos Johannes J Mager Martijn C Post 2015World Journal of Cardiology2015,7,5:4
