AIM： TO introduce a new method： small endoscopic sphincterotomy （ES） combined with endoscopic papillary large balloon dilation （SES ＋ EPLBD） to treat patients with large biliary stones.METHODS： Retrieval of large biliary stones was performed in 88 patients. Mean stone size was 14 ± 3 mm and mean number of stones was 2.5 ± 3.5. Firstly, ES with a small incision was performed. Next, endoscopic papillary dilation was performed with a large balloon to slowly match the size of the bile duct. Stones were then retrieved from the biliary duct with a balloon and a basket.RESULTS： Stone retrieval was successful in all cases except one cystic duct stone case without the need to crush large stones. Mean procedure time was 30 ± 5 min. Dilating the papillary orifice with a large balloon made it possible to remove large stones smoothly without crushing them. After dilation with the large balloon, there were some instances of oozing, but no perforations. One instance of post-procedural pancreatitis （1%） occurred. CONCLUSION： SES ＋ EPLBD was effective for the retrieval of large biliary stones without the use of mechanical lithotripsy.

Hydrogen energy became the most significant energy as the current demand gradually starts to increase. Hydrogen energy is an important key solution to tackle the global temperature rise. The key important factor of hydrogen production is the hydrogen economy. Hydrogen production technologies are commercially available, while some of these technologies are still under development. This paper reviews the hydrogen production technologies from both fossil and non-fossil fuels such as (steam reforming, partial oxidation, auto thermal, pyrolysis, and plasma technology). Additionally, water electrolysis technology was reviewed. Water electrolysis can be combined with the renewable energy to get eco-friendly technology. Currently, the maximum hydrogen fuel productions were registered from the steam reforming, gasification, and partial oxidation technologies using fossil fuels. These technologies have different challenges such as the total energy consumption and carbon emissions to the environment are still too high. A novel non-fossil fuel method [ammonia NH3] for hydrogen production using plasma technology was reviewed. Ammonia decomposition using plasma technology without and with a catalyst to produce pure hydrogen was considered as compared case studies. It was showed that the efficiency of ammonia decomposition using the catalyst was higher than ammonia decomposition without the catalyst. The maximum hydrogen energy efficiency obtained from the developed ammonia decomposition system was 28.3% with a hydrogen purity of 99.99%. The development of ammonia decomposition processes is continues for hydrogen production, and it will likely become commercial and be used as a pure hydrogen energy source.

The authors synthesized very pure dimer phase of coroneae by simple heat-treatment and subsequent sublimation purification. It was confirmed by laser desorption/ionization mass spectroscopy measurements that pure dimer phase of coronenes can be obtained by controlling the fusing and sublimation temperatures. The crystal structure of the dimer phase was analyzed by synchrotron XRD （X-ray diffraction） experiments. It was also found that very bright red light is emitted by irradiating ultra violet light （λ = 350 nm） to the dimer phase. The external and internal quantum yields were determined to be 5.56% and 6.95%, respectively.

AIM: To investigate the time course of testosterone(T) recovery after cessation of androgen deprivation therapy(ADT) in patients treated with brachytherapy. METHODS: One-hundred and seventy-four patients treated between June 1999 and February 2009 were studied. Patients were divided into a short-term usage group(≤ 12 mo, n = 91) and a long-term usage group(≥ 36 mo, n = 83) according to the duration of gonadotropin-releasing hormone agonist therapy. Median follow-up was 29 mo in the short-term group and was 60 mo in the long-term ***: Cumulative incidence rates of T recovery to normal and supracastrate levels at 24 mo after cessationwere 28.8% and 74.6%, respectively, in the long-term usage group, whereas these values were 96.4% and 98.8% in the short-term usage group. T recovery to normal and supracastrate levels occurred significantly more rapidly in the short-term than in the long-term usage group(P < 0.001 and P < 0.001, respectively). Five years after cessation, 22.6% of patients maintained a castrate T level in the long-term usage group. On multivariate analysis, lower T levels(< 10 ng/d L) at cessation of ADT was significantly associated with prolonged T recovery to supracastrate levels in the longterm usage group(P = 0.002). CONCLUSION: Lower T levels at cessation of ADT were associated with prolonged T recovery in the longterm usage group. Five years after cessation of longterm ADT, approximately one-fifth of patients still had castrate T levels. When determining the therapeutic effect, especially biochemical control, we should consider this delay in T recovery.

在旧石器时代晚期,中国北方的地域性石器工业之中也有石叶技术。最典型的实例是山西峙峪的,其特征是:1)制作技术简单;2)生产小型—中型石叶;3)石料的材料较好;4)在技术体系当中的作用较低。根据这些特征的有无,可以将中国北部的石叶技术划分为许家窑以前的阶段、许家窑阶段(10—3.5万年前)、峙峪—小南海阶段(3.5—1.7万年前)这样3个阶段。本文主张这3个阶段分别相当于欧亚大陆西部的旧石器时代早、中、晚期。

摘要本文借鉴日本细石叶工业的研究范例，运用高倍微痕分析法对许昌人遗址第5层出土的细石器功能进行分析。结果显示，220件细石叶多为不带使用痕迹，端刮器中19．3％带有明显使用痕迹，雕刻器、钻器、琢背小刀未发现明显使用痕迹。通过研究端刮器使用痕迹推测其可能用于鞣皮等工作。本文研究对于深入探讨许昌人遗址古人类细石器技术，以及人类的适应生存能力具有重要意义，同时对探讨细石器在东北亚扩散的路径和机制也有重要的参考价值。

本文应用20年(1981—2000年)的卫星数据反演归一化差值植被指数(NDVI),同时获取地面格网的温度与降雨数据,并分析这些数据之间的关系。基于地面的温度和降雨格网数据将研究区划分为8个气候区域,再利用NDVI数据把降雨量最少的3个气候区——区1,2,3各划分为10个等级。此外,分析这3个气候区在1983—1998年15年间的NDVI变化状况,结果显示出研究区荒漠化状况的加剧。
