Plastic and Aesthetic Research 2017年第10期4卷 195-203页

Aim: Autologous tissue transfer to salvage breast reconstruction following a previously failed or unsatisfactory reconstruction has been described by previous studies to be an effective strategy to optimize outcomes. The purpose of this systematic review is to assimilate the relevant literature to evaluate surgical and aesthetic outcomes following autologous breast reconstruction in the setting of a prior unsuccessful reconstruction. Methods: A systematic review of the English literature was performed on Pubmed/MEDLINE to identify all manuscripts reporting surgical outcomes, aesthetic outcomes, or patient satisfaction of autologous breast reconstruction in the setting of a previously failed or unsatisfactory breast ***: Nineteen studies met the criteria for inclusion. Of these, 15 studies reported outcomes following autologous conversion of unsuccessful prosthetic reconstruction (778 breasts). Pooled-analysis of these studies demonstrated total flap loss in 1.6%, microsurgical revision in 3.2%, total complications in 21.7%, and revision surgery in 26.5%. Review of these studies demonstrated high rates of positive aesthetic outcomes and patient satisfaction. Five studies (54 patients) evaluated outcomes following autologous salvage of prior unsuccessful autologous breast reconstruction. Pooled-analysis of these studies demonstrated no instances of microsurgical revision, total complications in 42.2%, and revision surgery in 70.0%.Total flap failure following tertiary reconstruction utilizing microsurgical free flaps occurred in 9.5%. Data describing aesthetic outcomes or patient satisfaction was lacking in these studies. conclusion: Autologous conversion in the setting of unsuccessful prosthetic breast reconstruction appears to be valuable option to improve outcomes. There is little evidence to suggest that prior prosthetic reconstruction negatively impacts outcomes of autologous breast reconstruction. Data describing autologous breast reconstructi

聚环氧乙烯醚-聚环氧丙烯醚-聚环氧乙烯醚(EO20PO70EO20)三嵌段高分子为模板剂制备了SBA-15分子筛.用3-氨丙基-三乙氧基硅烷对SBA-15进行改性,改性后SBA-15表面上的氨基再与(+)O-,O′-二苯甲酰基-L-酒石酸酐(DBTA)进行酰化反应,以酰胺键将该手性羧酸连接在SBA-15表面上.XRD和氮气吸附结果表明,材料经过处理后仍然保持良好的孔性质;13c和29S i魔角旋转核磁共振(MAS NMR)谱图表明,SBA-15与氨丙基化合物的作用是共价成键,表面修饰度达25%;从傅里叶变换红外(FTIR)光谱可见,有部分修饰氨基与DBTA成功地进行了酰化反应,以一个羧基裸露的形式将该二元羧酸化合物连接在表面上;从孔径分布图可知,胺丙基修饰之后孔减小了1.5 nm,与DBTA修饰后孔尺寸又减少0.5 nm,说明胺丙基化合物是头对头垂直连接在S i表面上,而酒石酸分子是采取平行方式侧卧在氨基表面.

Middle to Late Jurassic belemnites from the Spiti and Zanskar valleys in the Indian Himalayas were used for stable isotope(δ^(13)c, δ^(18)O) and element(Mg/ca, Sr/ca) analyses. Although the Himalayan orogeny deformed and altered a large portion of the collected fossils, cathodoluminescence and scanning electron microscopy in combination with analyses of iron and manganese contents allowed the identification of belemnites believed to still retain their original chemical composition. Results indicate a long-term temperature decrease from the Middle callovian–Oxfordian to the Tithonian, which is proposed to have been caused by a concomitant drift of eastern Gondwana into higher palaeolatitudes. Reconstructed absolute temperatures depend on the used equation and assumed δ^(18)O value of seawater, but most likely varied between 17.6 ℃ to 27.6℃ in the Kimmeridgian and Tithonian with average values between 22 ℃ to 24 ℃. This way, temperatures were similar to slightly warmer than today at comparable latitudes. The reconstruction of absolute temperatures for the Middle callovian–Oxfordian was hindered by a larger number of poorly preserved belemnites representing this time interval.

co(II), Ni(II), cu(II) and Mn(II) complexes synthesized by reflux of 6-bromo-3-(3-(4-chlorophenyl)acryloyl)-2H- chromen-2-one, ciprofloxacin and various transition metal. 1H, 13c, IR and ESI Mass confirm the formation of ligand. The metal complexes were characterized on the basis of various spectroscopic techniques like IR studies and elemental analysis while the geometry of complexes was octahedral which is confirmed by electronic spectra and thermogravimetric analysis. The compounds were subjected to antimicrobial, antioxidant and anti-tubercular activity screening using serial broth dilution method and Minimum Inhibitory concentration (MIc) is determined. Mn(II) complex has shown significant antifungal activity with an MIc of 6.25 μg/ml while cu(II) complex is noticeable for antibacterial activity at the same concentration. Anti-TB activity of the ligand has enhanced on complexation with Ni(II) and co(II) ions. While Ni(II) complex shows superior antioxidant activity than other complexes.

目前,世界各国普遍采取跨部门行动解决健康的宏观社会和经济决定因素。"将健康融入所有政策(Hi AP)"是各国采取跨部门行动的策略之一,它以广义的健康决定因素而非单纯的卫生服务为目标,在决策过程中系统解决健康问题。近几十年来出现了很多关于Hi AP的案例,但这些案例成功或失败的原因并未得到系统的研究,这就导致以证据为基础的有关促进或阻碍Hi AP策略实施的相关因素的研究较少。本文基于现实主义视角,采用解释性案例研究,分析了不同地区Hi AP策略的实施情况。本研究在提出概念性框架的基础上,分析了与Hi AP可持续实施有关的背景、社会机制及结果,并利用相关文献以及从关键知情人访谈中得到的证据,寻找相关的模式和主题对现象加以解释。最后,通过对瑞典和加拿大魁北克实施卫生影响力评估的情况进行比较,揭示了Hi AP成功实施的经验。此方法能够帮助研究者对某一地区内成功实施Hi AP的社会机制和背景因素的大量证据信息加以审核并做三角测量,还可用于分析其他形式的部门间行动,以减少不同背景、不同地区之间的卫生不公平性现象。

coexistence of Duarte 1 and Duarte 2 variants of galactosemia with extrahepatic biliary atresia

引用

Health 2010年第4期2卷 286-290页

作者： Ramandeep Singh ketan Kulkarni Gurjit Kaur Babu Ram Thapa Rajendra Prasad 不详

Galactosemia is an autosomal recessive disorder caused by deficient or absent activities of one of the three enzymes involved in the galactose metabolic pathway. The predominant form is classic type galactosemia caused by severe reduction or absence of the galactose- 1-phosphate uridyl transferase (GALT) enzyme. coexistence of extrahepatic biliary atresia (EHBA) with Duarte 1 and 2 variants of galactosemia has not been described earlier. Here we report a case of EHBA with concordant Duarte 1 and 2 variants of galactosemia in an infant with cholestasis. Genetic analysis of the index patient for galactosemia revealed presence of Duarte 1/Duarte 2 variants of galactosemia with genotype N314D-L218L/N314D-G1105c-GI391A- G1323A-5’UTR-119delGTcA. clinical evaluation of the patient showed the presence of EHBA. Henceforth, it may be hypothesized that EHBA may have a genetic basis with simultaneous involvement of the GALT gene.

Improvement of Plasma Performance with Lithium Wall conditioning in Aditya Tokamak

Lithiumization of the vacuum vessel wall of the Aditya tokamak using a lithium rod exposed to glow discharge cleaning plasma has been done to understand its effect on plasma performance. After the Li-coating, an increment of ~100 eV in plasma electron temperature has been observed in most of the discharges compared to discharges without Li coating, and the shot reproducibility is considerably improved. Detailed studies of impurity behaviour and hydrogen recycling are made in the Li coated discharges by observing spectral lines of hydrogen, carbon, and oxygen in the visible region using optical fiber, an interference filter, and PMT based systems. A large reduction in O I signal （up to ~40% to 50%） and a 20% to 30% decrease of Ha signal indicate significant reduction of wall recycling. Furthermore, VUV emissions from O V and Fe XV monitored by a grazing incidence monochromator also show the reduction. Lower Fe XV emission indicates the declined impurity penetration to the core plasma in the Li coated discharges. Significant increase of the particle and energy confinement times and the reduction of Zeff of the plasma certainly indicate the improved plasma parameters in the Aditya tokamak after lithium wall conditioning.

以温岭市某座异形钢箱梁为研究对象,对车辆在右转弯时轮迹的横向分布进行统计分析,得到其车辆轮迹横向分布概率模型;采用数值模拟方法,分别分析了实测轮迹横向分布及规范(JTG D64—2015)的轮迹横向分布对异形钢箱梁桥面板4种典型疲劳构造细节的疲劳应力幅的影响并进行了比较。结果表明:虽然转弯时轮迹中心线的分布宽度较直行时大,但在某个横向分布区间内表现出更大的集中性;车辆右转弯时,桥面板典型疲劳构造细节的疲劳应力幅受轮迹横向分布的影响十分显著;对于所选取的4种疲劳构造细节,在采用实测轮迹横向分布模型时其等效应力幅均小于规范规定的轮迹横向分布模型的等效应力幅,说明按规范(JTG D64—2015)的轮迹横向分布模型计算偏于安全。
