The rice straws were pretreated by acid-catalyzed steam explosion, and the reaction efficiency, toxicity control, and process economic feasibility were studied. Mass transfer resistance to the hydrolysis reaction was reduced by grinding with glass beads. A higher glucose concentration could be obtained by feeding more cellulose in the hydrolysis reaction; however, this also resulted in the production of undesired byproducts. Thus, a soaking process for the cellulose solids in water was developed to effectively reduce the generation of byproducts in the hydrolysis reaction. The resulting food-grade glucose solution can provide 414 kilocalories per liter, and could be used during a food-shortage crisis in the future.The current production cost is estimated to be 0.82 USD·L^(-1).展开更多

This systematic review was consequently performed to objectively investigate the analgesic effect of Oral GS related to NNS in newborns during nociceptive procedures. Methods： All potential records were searched in PubMed, Web of Science, EMBASE, and the Cochrane Library to capture the randomized controlled trials comparing GS with NNS in terms of pain scores in neonates through January 2017. Two independent investigators screened the identified articles, extracted the data, and assessed the methodological quality of the included studies. All statistical analyses were completed by using Review Manager （RevMan） version 5.3.0. Results： Four studies, involving 248 neonates, were incorporated into these statistical analyses. For reducing pain scores, no statistical difference was detected when GS compared to NNS （4 trials; mean difference [MD], 0.75; 95% confidence interval [CI], -0.77 to 2.27; P = 0.33）. Conclusion： Both the GS and NNS reduced the pain scores in neonates who undergoing Hepatitis B vaccination and venipuncture, but the NNS is more convenience than GS to some extent. Considered the limited evidences, more randomized controlled trials with high-quality, large-scale and appropriate measures time are warranted to further establish the comparative efficacy of these two options.展开更多
