Background The delayed diagnosis of pelvi-ureteric junction （PUJ） disruption in children following blunt abdominal trauma can result in loss of function of the involved kidney. We examined the potential for kidney preservation and the limits of diagnostic delays. Methods A retrospective review of 17 cases of PUJ disruption at Beijing Children＇s Hospital from 1993 to 2009 was done with respect to diagnosis, treatment and follow-up. Results The interval from trauma to diagnosis of PUJ disruption was （52＋52） days. If one case with nephrectomy was excluded, the interval from trauma to diagnosis was （40＋_20） days. The average time between injury and first treatment was （49＋_25） days. Pelvi-ureteric reanastomosis and caliceal ureterostomy were performed separately in 11 and 4 patients, respectively. Ileal replacement for ureter injuries was finally performed in one patient. Hydronephrosis of the injured kidney was reduced and the function improved in 15 out of 17 patients （88%）. Only one patient received nephrectomy and the nephrectomy rate was 5.9%. Conclusion Differential renal function at the PUJ disruption side can be saved and the rate of nephrectomy reduced by appropriate surqen/if the time to diaqnosis and first treatment is limited to within two months.

A comparative study on the laser performance between bonding and non-bonding Er,Pr:GYSGG rods side-pumped by 970-nm laser diodes(LDs) is conducted for the thermal lensing compensation. The analyses of the thermal distribution and thermal focal length show that the bonding rod possesses a high cooling efficiency and weak thermal lensing effect compared with the conventional Er,Pr:GYSGG rod. Moreover, the laser characteristics of maximum output power, slope efficiency, and laser beam quality of the bonding rod with concave end-faces operated at 2.79 μm are improved under the high-repetition-rate operation. A maximum output power of 13.96 W is achieved at 150-Hz and 200-μs pulse width,corresponding to a slope efficiency of 17.7% and an electrical-to-optical efficiency of 12.9%. All results suggest that the combination of thermal bonding and concave end-face is a suitable structure for thermal lensing compensation.

利用2008—2017年4—10月山东省加密自动气象观测站(简称全部站)和国家气象观测站(简称国家站)逐小时1 mm以上降水量资料,通过对比分析,探究不同分辨率数据对极端短时强降水时空分布特征的刻画效果。结果表明如下:全部站小时降水量的偏态特征比国家站明显,若分析小时降水量的平均状态,两者均具有代表性,若分析短时强降水的极端性,全部站数据更具有优越性。将各站第99.5%分位数作为极端短时强降水的阈值最合理,全部站和国家站对于30~45 mm阈值的空间分布特征相似,45 mm以上的阈值,全部站的数值和范围均大于国家站。山东省大部地区的极端短时强降水强度集中在40~60 mm·h-1,全部站和国家站在此区间的空间分布特征相似。国家站数据不能刻画40 mm·h-1以下和60 mm·h-1以上的极端短时强降水的空间分布特征。极端短时强降水强度的空间分布特征与地理位置及地形特征密切相关。鲁东南地区的极端短时强降水强度、日最大降水量及夏季降水量、年降水量均居山东省之首,鲁西北地区虽然强降水频次高、强度大,但与年降水量和夏季降水量没有正相关关系。全部站与国家站极端短时强降水频次的月变化和日变化特征一致,但国家站不能完全代表山东省极端短时强降水强度的月变化和日变化平均状况,全部站数据能更准确地反映山东省的时间变化特征。
