A 52-year-old man was referred for further investigation of a gastric submucosal tumor on the greater curvature of the antrum. Endoscopic ultrasonography demonstrated a hypoechoic solid mass, which was primarily connected to the muscular layer of the stomach. We performed endoscopic ultrasoundguided fine-needle aspiration biopsy. The pathological examination showed proliferation of oval-shaped cells with nest formation, which stained strongly positive for muscle actin, and negative for c-kit, CD34, CD56,desmin, S-100, chromogranin, and neuron-specific enolase. Therefore, we performed laparoscopy and endoscopy cooperative surgery based on the preoperative diagnosis of glomus tumor of the stomach. The final histological diagnosis confirmed the preoperative diagnosis. Although preoperative diagnosis of glomus tumor of the stomach is difficult with conventional images and endoscopic biopsy, endoscopic ultrasoundguided fine-needle aspiration biopsy is an essential tool to gain histological evidence of glomus tumor of the stomach for early diagnosis.

＜正＞Dual fluidized bed gasification （DFBG） allows the production of middle-caloric gas free of serious dilution by N2 of combustion air. It is particularly suitable to thermal conversion of biomass at energy capacities of tens to hundred of MW because of its involvement of fluidized bed gasifier that has to run at temperatures below 1173 K. This article concerns the application of DFBG to various high water content residues generated in beverage, seasoner and food industries. These residues, such as coffee grounds, tee grounds, vinegar lees and bagasse, represent a kind of biomass resources that are concentrated already. A few potential technical means were proposed and further tested in a 5.0 kg/h pilot gasification facility to increase gasification efficiency and suppress tar evolution. These include the choice of superior technical deployment for DFBG, the impregnation of Ca onto fuel in fuel drying, and the integration of gas cleaning with fuel gasification via two-stage DFBG （T-DFBG）. The attained results demonstrated that all the means were effective to certain degrees, but the Ca-impregnated fuel exhibited distinctively high upgrades for both fuel conversion efficiency and tar elimination capability. An advanced approach called the decoupled DFBG （D-DFBG） was also devised to gasify high water content biomass directly by making use of vaporized fuel water as part of steam reagent and taking advantage of the catalysis of char to eliminate tars.

A novel carbonaceous adsorbent for heavy metal removal was prepared from raw coal by one-step simple sulfur impregnation using K2S. Raw coal was mixed with K2S powder and then heated at 800℃ for 30 min in nitrogen to produce K2S char. The sulfur content and form in K2S char were determined, and the ability of K2S char to adsorb Zn^2＋, Cd^2＋ and Pb^2＋ was examined. The K2S impregnation was effective at impregnating sulfur into coal, especially in the form of elemental, thiophenic and sulfatic sulfur. The sulfur content of K2S char was higher than those of raw coal and pyrolysis char. The Zn^2＋ removal in 2.4 mmol/L of Zn^2＋ solution by K2S char was higher than raw coal with the removal rate of 100%. K2S char adsorbed Pb^2＋ and Cd^2＋ in 24 mmol/L of Pb^2＋ and Cd^2＋ solution with the removal rate of 97% and 35%, respectively. The elution extents of adsorbed Pb^2＋ and Cd^2＋ were zero in distilled water and 27% in 0.1 mol/L HCl solution. These results indicated that an effective adsorbent for heavy metal ions was prepared from coal using K2S sulfur impregnation, and that the adsorbed metals were strongly retained in K2S char.
