Background Dihydropyrimidine dehydrogenase （DPD）, a key enzyme involved in the catabolism of 5-fluorouracil （5-FU）, is the attractive candidate for pharmacogenetic research on efficacies and toxicities of 5-FU. The aim of this study is to explore the association between polymorphisms of dihydropyrimidine dehydrogenase gene （DPYD） and clinical outcomes of gastric cancer patients treated with fluorouracil-based adjuvant chemotherapy in the Chinese population.

目的探讨复合手术治疗急性下肢缺血性腘动脉瘤的早期疗效。方法 2004年8月至2007年6月收治合并急性下肢缺血的腘动脉瘤患者7例,采用外科手术与血管介入相结合的复合手术方式进行治疗。复合手术包括传统的手术切除,结合手术前后置管溶栓、球囊扩张、术中球囊导管取栓等。方法观察围手术期并发症及早期治疗效果并对相关文献进行分析。结果外科手术包括动脉瘤旷置术2例,动脉瘤切除术5例。动脉瘤切除后重建方法包括人工血管置换术6例,自体动脉端端吻合1例。血管介入包括手术前后球囊扩张及置管溶栓7例,1例行术中取栓。围手术期无严重并发症,术后1周的踝肱指数较术前明显改善(0.68～0.98比0.22～0.52,P<0.001)。术后随访人工血管通畅,动脉瘤远近端侧支循环保留,肢体感觉及运动功能良好。结论复合手术保留了侧支循环,可以降低术后肢体远端缺血的风险;介入方法的使用保证了术后流出道的通畅,有助于避免术后移植物急性闭塞,从而有效降低术后截肢率。

目的评估平阳霉素碘油混合液联合无水乙醇超选择动脉栓塞治疗孤立肾错构瘤的有效性及安全性。方法回顾性分析2009年5月至2015年10月收治的6例孤立肾错构瘤患者。所有患者接受多次超选择动脉栓塞术,根据每次随访结果以不同栓塞材料再次作栓塞治疗。采用CT增强或MRI平扫检查随访患者病灶清除率及复发情况。结果 6例患者每次栓塞术均成功,技术成功率100%。每例患者平均手术3次,平均手术间隔时间约1年,平均随访时间2.5年。术后3、6、12个月随访提示平阳霉素碘油混合液联合PVA颗粒栓塞可缩小病灶,但不能清除病灶;平阳霉素碘油混合液联合无水乙醇栓塞可清除病灶,远期随访未见原病灶复发。结论平阳霉素碘油混合液联合无水乙醇可安全有效地栓塞肾错构瘤,可能是孤立肾错构瘤患者栓塞治疗的较好材料。

Layered rare-earth metal oxides, harnessing the dual properties of oxides and two-dimensional layered materials, exhibit remarkable thermal stability and quantum confinement effects. Therefore, this work adopts the first-principles calculation combined with the Boltzmann transport theory to predict the thermoelectric properties of NdZnSbO compound. The coexistence of weak interlayer van der Waals interactions, robust intralayer ionic bonding, and partial covalent bonding leads to remarkable bonding heterogeneity, which engenders pronounced phonon scattering and imposes constraints on thermal transport along the out-of-plane direction. The weakened chemical bonds induced by the antibonding states, together with the rattling-like behavior of the Zn atom, culminate in the profound anharmonicity in the layered NdZnSbO compound. The weakening bond and heavy element contribute to the softness of phonon modes, which significantly diminishes the phonon group velocity. The redistribution-dominated four-phonon scattering process spans a large optical gap, which effectively reduces the lattice thermal conductivity. The NdZnSbO compound exhibits direct semiconductor characteristic with a bandgap of 0.73 e V by adopting the Heyd-Scuseria-Ernzerhof(HSE06) functional in combination with spin–orbit coupling(SOC) effect. The multi-valley feature of NdZnSbO compound augur favorably for band degeneracy, thus amplifying the power factor. Consequently, an optimal figure-of-merit(ZT) of 3.40 at 900 K is achieved for the n-type NdZnSbO compound. The present study delves deeply insights into the origins for the low thermal conductivity of NdZnSbO compound and proposes an optimization scheme to enhance overall thermoelectric performance.
