Background Improving the success rate of ureteroscopic lithotripsy for proximal ureteral stones is the hot issue in this field. Here we reported our experience on the treatment of proximal ureteral stones.Methods From 2005 to 2010, 187 consecutive patients with proximal ureteral stones who underwent ureteroscopic lithotripsy were enrolled. The initial 52 patients treated by semi-rigid ureteroscope alone were classified as group 1. The subsequent 135 patients treated by semi-rigid ureteroscope with the aid of stone basket and flexible ureteroscope were classified as group 2.Results In group 1, the overall stone-free rate was 67.3%. By a single procedure of ureteroscopic lithotripsy using a semi-rigid instrument, patients with ureteral stones below the 4th lumbar vertebra level achieved 91.7% stone-free rate, which was only 50% in patients with stones above the 4th lumbar vertebra level. Conversion to open surgery occurred in two patients since ureteral perforation was observed. In group 2, the stone-free rate achieved 93.2% with the aid of an N-Trap basket, which was significantly higher than that of patients without the aid of the basket （51.6%）. Flexible ureteroscope was subsequently used in patients with fragment migration, thus making the overall success rate in group 2 increases to 97.0%.Conclusions Ureteroscopic lithotripsy is a safe and efficacious treatment for proximal ureteral stones. A single procedure of ureteroscopic lithotripsy using semi-rigid ureteroscope could achieve a satisfactory stone-free rate in patients with proximal ureteral stones below the 4th lumbar vertebra level. However, patients with ureteral stones above the 4th lumbar vertebra level experienced higher stone-migration rate, which would decrease the success rate. Fortunately, the stone-free state could possibly be achieved with the aid of an N-trap basket and flexible ureteroscope.

We performed a retrospective analysis to investigate dynamic peri-hematopoieticstem cell transplantation(HSCT)minimal/measurable residual disease(MRD)on outcomes inpatients with T-cell acute lymphoblastic leukemia(T-ALL).A total of 271 patients were enrolledand classified into three groups:unchanged ncgative MRD pre-and post-HSCT group(group A),post-MRD non-increase group(group B),and post-MRD increase group(group C).The patientsin group B and group C experienced a higher cumulative incidence of relapse(CIR)(42%vs.71%vs.16%,P<0.001)and lower leukemia-free survival(LFS)(46%vs.21%vs.70%,P<0.001)andoverall survival(OS)(50%vs.28%vs.72%,P<0.001)than in group A,but there was no significantdifference in non-relapse mortality(NRM)among three groups(14%vs.12%vs.8%,P=0.752).Multivariate analysis showed that dynamic peri-HSCT MRD was associated with CIR(HR=2.392,95%CI,1.816-3.151,P<0.001),LFS(HR=1.964,95%CI,1.546-2.496,P<0.001)and os(HR=1.731,95%CI,1.348-2.222,P<0.001).We also established a risk scoring system based ondynamic peri-HSCT MRD combined with remission status pre-HSCT and onsct of chronic graft-versus-host disease(GVHD).This risk scoring system could better distinguish ClR(c=0.730)thanthat for pre-HSCT MRD(c=0.562),post-HSCT MRD(c=0.616)and pre-and post-MRD dynamics(c=0.648).Our results confirm the outcome predictive value of dynamic peri-HSCT MRD eitheralone or in combination with other variables for patients with T-ALL.

叶面追肥是现代农业作物丰产栽培常用田管技术。为探明叶面施氮次数与浓度对花生氮素吸收积累、运转分配及利用率影响,揭示叶面追氮对植株不同器官建成和功能维持的营养机制,试验设5个处理:T0为对照;T1尿素浓度1%,收获前35d追施1次;T2尿素浓度3%,追施时间同T1;T3尿素浓度1%,收获前50 d、35 d和20 d追施3次;T4尿素浓度3%,追施时间同T3。氮肥用^(15)N标记尿素和普通尿素。结果表明:(1)叶面施氮植株氮含量提高0~0.22个百分点,且有T4>T3>T2>T1,其中营养体(根、茎、叶)增幅较大,比对照提高0.17~0.45个百分点,生殖体含量(果针、果壳、籽仁)增幅较少;施氮处理植株氮积累量提高平均19.8%,其中营养体平均增42.1%,生殖体平均增长12.7%。(2)叶面追施的氮在不同器官的分配比例存在较大差异,籽仁>叶>茎>果壳>果针>根,其中籽仁、叶各约占60%和30%,其余器官比例较少;追施时间对氮素分配有一定影响,收获前35 d追施更有利向生殖体分配,比收获前50 d和20 d两处理平均高7.9个百分点。(3)植株氮素效率随叶面施氮数量的增加而降低;施氮次数少或氮肥浓度低肥料利用率高,1次追施氮肥利用率平均70.6%,比3次追施平均高37.7个百分点;不同追施时间比较,收获前35 d追施氮肥利用率最高,较收获前50 d和20 d两处理的平均值分别高1.8和3.9个百分点。综上,叶面施氮可显著提高植株氮代谢水平,促进氮素吸收、积累,营养体尤为明显,是花生生育后期“护根保叶”生理机制和根系氮源难以取代的技术措施;叶面追施的氮主要分配在荚果和叶片中,是花生提高产量和叶片光合作用的生理机制;叶面追氮肥料利用率明显高于根系施肥,是花生经济施肥的有效途径;植株氮效率随叶面施氮数量的增加而降低,追施次数少或氮肥浓度低肥料利用率高。本研究可为花生叶面施肥提供理论依据和技术支撑。
