Somatostatinoma is a very rare neuroendocrine tumor that originates from D cells and accounts for less than 1% of all gastrointestinal endocrine tumors. The duodenum is the most frequent site for this tumor, followed by the pancreas. We here describe a 46-year-old Chinese woman who developed pancreatic somatostatinoma presenting with the characteristic "inhibitory" syndrome, but the symptoms were obscure and seemingly uncorrelated. This case is also unique for its large tumor size and mixed pathological pattern. distal pancreatectomy was performed, and the patient has remained well since operation. As the syndromes of somatostatinoma may be obscure and atypical, clinicians should review all clinical findings to obtain an accurate diagnosis. Aggressive surgery is preferred to improve the survival.

We investigate high time resolution data obtained by the Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor(GECAM)during the flare event on 2022 April 21 at 01:52 *** subpeaks with durations of 4-6 s have been detected in the hard X-ray precursor phase,and the key feature is that they appear in pairs and seem like double-peak *** subpeaks are rarely observed in hard X-ray band and confirmed by the microwave obtained by Nobeyama Radio Polarimeters(NoRP)and Radio Solar Telescope Network(RSTN).While an exponential function can describe the continuum component of the time profile from the precursor to part of the impulsive *** periods of quasi-periodic pulsations(QPPs)are detected to be about 7.3 and 12.8 s for the precursor and impulsive phase,respectively,with at least 95%confidence *** paired QPPs are assumed to be double-peak QPPs and then the scenario of current loop coalescence model is found to be in good agreement with our *** precursor phase can be interpreted as the oscillating coalescence of two islands,while the impulsive phase can be interpreted as more islands to coalesce one by one to form larger islands.

[目的]为探索在不同农药制剂浓度下无人机(UAV)对烟草传毒蓟马和番茄斑萎病毒(TSWV)防治效果的影响,同时探明蓟马和TSWV的有效防治节点及防治方式。[方法]根据蓟马和TSWV发生特点,遵循全区域、周期性防治试验原则,以蓟马数和病情指数为指标,应用UAV测试4种农药对蓟马和TSWV的田间防治效果。[结果]在不同药液处理下的UAV和人工防治组中,交替使用1%甲氨基阿维菌素苯甲酸盐微乳剂、1.7%阿维·吡虫啉微乳剂、5%甲氨基阿维菌素苯甲酸盐水分散粒剂、30%吡丙·呋虫胺可溶液剂4种药剂,处理1(UAV药剂推荐用药量)、处理2(UAV药剂推荐用药量减量25%)和处理4(人工防治药剂推荐用药量)的蓟马及TSWV防治效果均无显著差异,3个处理的蓟马防效均在83.16%以上,3个处理的TSWV病情指数由空白对照组的8.64±1.37下降到了3以下,均达到防治指标,但处理3(UAV药剂推荐用药量减量50%)未达到防治指标;空白对照区内的TSWV病情指数随着蓟马活若虫数量的增加而升高,存在显著正相关性,且具有极好的拟合度。[结论]不同农药制剂浓度下UAV对蓟马和TSWV防治效果的影响存在显著影响,实际飞防操作中,建议用药质量为人工的3/4左右,不少于人工施药的1/2;将防治区域外扩到烟田埂100 m范围内,从烤烟移栽前到现蕾前进行为期5次的周期性UAV防治蓟马和TSWV,防治效果显著,明显区别于传统人工施药。

在基于白光中子源的中子核反应测量中,伴随中子束的伽马射线是重要的实验本底之一.本文对中国散裂中子源反角白光中子源的束内伽马射线进行了研究.通过蒙特卡罗模拟,得到了伽马射线的能量分布和时间结构.通过直接测量和间接测量两种方法测得低能中子区的束内伽马射线的时间结构.直接测量实验中,将载6Li的ZnS(Ag)闪烁体探测器置于束流线上,通过飞行时间法直接测量束内的中子和伽马射线的时间结构,并利用波形甄别技术进行粒子鉴别.间接测量法是将铅样品置于束流线上,利用C6D6闪烁体探测器测量样品上的散射伽马射线,从而得到入射伽马射线的时间结构.实验测量结果与模拟结果在12μs—2.0 ms的时间区间内具有较好的一致性.
