BACKGROUND Gallbladder adenomyomatosis(GAM) is a benign lesion, characterized by thickening of the gallbladder wall and a focal mass, which overlap with the features of gallbladder malignancy. Consequently, differential diagnosis of GAM from gallbladder cancer is difficult and approximately 20% of suspected malignant biliary strictures are postoperatively confirmed as benign ***, we report a case in which a preoperative diagnosis of GAM was made by a combination of endoscopic and imaging *** SUMMARY A 40-year-old man was referred to our hospital chiefly for a fever and right upper abdominal pain with dark urine. Enhanced computed tomography showed thickening of the gallbladder wall and a mass in the gallbladder neck with involvement of the hepatic bile ducts, which was suspected to be *** malignancy with bile duct invasion was ruled out by subsequent endoscopic examinations, including endoscopic retrograde cholangiopancreatography, intraductal ultrasound, and Spy Glass. Endoscopic examinations showed a homogeneous hyperechoic lesion with smooth margins of benign bile duct stricture suggestive of inflammatory stenosis of the bile *** patient underwent laparoscopic cholecystectomy. GAM was postoperatively diagnosed and confirmed based on the histopathology results, which are consistent with the preoperative diagnosis. Notably, no malignant event occurred in the patient during a 12-mo follow-up *** A combination of endoscopic techniques may help in the differential diagnosis of GAM from gallbladder cancer.

Characterization of aqueous extract in traditional Chinese medicine(TCM) is challenging due to the poor retention of the analytes on conventional C18 columns. This study presents a systematic characterization method based on a rapid chromatographic separation(8 min) on a polar-modified C18(Waters Cortecs T3) column of aqueous extract of Cordyceps sinensis. UHPLC-HRMS method was used to profile components in both untargeted and targeted manners by full MS/PIL/dd-MS2 acquisition approach. The components were identified or tentatively identified by reference standards comparison, fragmentation rules elucidation and available databases search. A total of 91 components, including 10 nucleobases, 20 nucleosides, 39 dipeptides, 18 amino acids and derivatives and 4 other components, were characterized from the aqueous extract of C. sinensis. And this was the first time to systematically report the presence of nucleosides and dipeptides in C. sinensis, especially for modified nucleosides. The chemical basis inquiry of this work would be beneficial to mechanism exploration and quality control of C. sinensis and related products. Meanwhile, this work also provided an effective solution for characterization of aqueous extract in TCM.

An eco-friendly and fast HPLC method was developed for the determination of adenosine, inosine, guanosine and uridine in Cordyceps and related products(fermented mycelia of Hirsutella sinensis and Paecilomyces hepiali). The sample was ultrasonically extracted using 0.5% phosphoric acid solutions for 2.5 min. Sample separation was performed on a Poroshell SB-Aq column(50 mm × 4.6 mm, 2.7 μm) using eco-friendly mobile phase consisting of formic acid and ammonium formate aqueous solution at a flow rate of 1.0 m L·min;. The detection wavelength was 260 nm. The developed HPLC method showed good linearity with correlation coefficients of 1.0000 in the test range. Good precision, repeatability and stability of this method were also observed(RSD ≤ 2.81%).The recovery ranged from 91.84%-105.19%(RSD ≤ 2.59%). Compared with reported methods, the current method did not use harmful organic solvent and took only 10.5 min. It obtained a high eco-score of 91 by the "Analytical Eco-Scale" tool. The developed method is eco-friendly and fast, which is suitable for the quality evaluation of Cordyceps and related products.

为了实现微机器人的快速批量制造,提出一种飞秒贝塞尔光束叠加干涉方法生成带侧瓣的环形光场,并结合动态全息加工术实现了中空螺旋微机器人的高效制造。对根据贝塞尔传输函数生成的贝塞尔全息图进行叠加,并对产生的光场进行仿真和实验测量。利用叠加的全息图加工得到具有不同侧瓣数目(2~4)的环形结构,分析了两种不同参数对侧瓣宽度和圆环直径的影响。通过引入动态全息加工方法,实现了中空双螺旋微机器人的高效快速加工,微机器人宽为25μm、长度为100μm。最后,利用旋转磁场驱动微机器人在微流体环境实现运动。实验表明,加工单个微机器人仅需6 s,旋转磁场下微机器人在7 s内沿直线前进400μm。该动态全息方法能够快速制备出中空双螺旋微机器人并实现无线磁驱动,为批量制造具有运载能力的磁驱微机器人提供了一种新的途径。

本文提出了太阳能光伏电池与甲醇中低温重整反应相结合的发电系统;通过太阳能的梯级利用以及物理能与化学能之间的品位耦合,太阳能净发电效率较单一光伏或甲醇热化学发电方式获得显著提升。热力学分析表明,在100~250℃C的系统运行温度范围内,系统的理论太阳能净发电效率达43.6%~44.3%(已考虑光学损失),显著高于光伏系统(22.5%)及热化学系统(32.7%)。系统约50%的太阳净发电量来自甲醇重整产物氢气,以化学能形式实现了太阳能的高效储能,且光伏、热化学发电随温度变化的相反趋势间互补达到了稳定输出的效果。此外,系统产生的电能中约25%来自太阳能,高于单一太阳能甲醇热化学发电系统的14%,对化石能源的依赖度降低。光伏与热化学互补发电为太阳能高效综合利用提供了新的思路。
