Statistically significant differences in ABG difference between the two groups were observed 18 months after surgery with cured and total effective rates of BET at 76.1 and 93.5%, respectively. In the control group, these rates were 60.9 and 89.1% respectively. No serious complications and tympanic perforations were found in all subjects. CONCLUSION MTI combined with BET is effective and safe in the treatment of children with OME. Compared to simple MTI, application of BET can effectively extend improvement period and increase cured rate, especially after removal of the ventilation tube. Directly benefit from the ventilation tube, the curative effect was close during the period of tube retention. Considering the sample size and follow-up time of this study, related studies targeting large cohorts are needed in the future to validate the benefits of BET in children with OME.While the hydrogen economy is receiving growing attention, research on microbial hydrogen production is also increasing. Microbial water-gas shift reaction is advantageous as it produces hydrogen from by product gas including carbon monoxide (CO). However, CO solubility in water is the bottleneck of this process by low mass transfer. Thermococcus onnurineus NA1 strain can endure a high-pressure environment and can enhance hydrogen production in a pressurized reactor by increasing CO solubility. As CO causes cell toxicity, two important factors, pressure and input gas flow rate, should be considered for process control during cultivation. Hence, we employed different operational strategies for enhancing hydrogen production and obtained 577 mmol/L/h of hydrogen productivity. This is the highest hydrogen productivity reported to date from microbial water-gas shift reaction.Intracellular pathogens need to develop sophisticated mechanisms to su
