Background and Aims:Rifaximin is effective in prevent-ing and treating hepatic encephalopathy(HE).This study aimed to investigate the efficacy and safety of different dosages of rifaximin in the treatment of cirrhotic patients with covert HE(CHE).Methods:In this single-center,ran-domized,controlled,open-label study,CHE was diagnosed using a combination of the psychometric HE score and the EncephalApp Stroop test.Cirrhotic patients with CHE were recruited and randomly assigned to low-dose rifaximin 800 mg/day,high-dose rifaximin(1,200 mg/day),and control groups,and were treated for 8 weeks.The sickness impact profile(SIP)scale was used to evaluate the health-relat-ed quality of life(HRQOL)of patients.Forty patients were included in the study,12 were assigned to the low-dose group,14 to the high-dose group,and 14 patients to the control group.Results:The percentage of patients with CHE reversal was significantly higher in both the low-dose(41.67%,5/12)and high-dose(57.14%,8/14)groups than in the control group(7.14%,1/14)at 8 weeks(p=0.037 and p=0.005,respectively).In addition,both doses of ri-faximin resulted in significant improvement of the total SIP score compared with the control group.There were no sig-nificant differences in the CHE reversal rate,total SIP score improvement,and incidence of adverse event between the low-dose and high-dose groups(p>0.05).Conclusions:Low-dose rifaximin reverses CHE and improves HRQOL in cirrhotic patients with comparable effects and safety to high-dose rifaximin.

植被生态需水量的准确估算不仅关乎水资源的合理开发与管理,而且为科学制定生态环境保护与修复政策提供基础支持.本研究探讨应用不同方法估算河西地区植被生态需水量的精度与适用性.通过收集河西地区11个通量观测站的植被耗水观测数据,对植被生态需水模型进行验证和标定,选取适合该地区的估算模型——植被覆盖度修正蒸散发法,结合野外观测数据和卫星遥感数据,对2000—2020年河西地区的植被生态需水量进行估算.结果显示,河西地区2000—2020年植被生态需水量为(173.86±6.10)×10^(8)m^(3),在空间上呈现出东南高、西北低的分布格局.随着植被覆盖度以每年0.002的速率显著增加,植被生态需水量呈现出以每年0.70×10^(8)m^(3)的速率显著增加的趋势.本研究为河西地区植被生态需水量的准确估算和深入分析提供科学依据,同时也为未来相关研究提供参考和借鉴.

Corrosion failure accidents owing to flow erosion and pipeline corrosion frequently occur during transportation.The welding reinforcement height(WRH)can induce locally micro-turbulent flow field,which aggravates local corrosion of welded joints.A high wall shear stress(WsS)experimental setup was established to conduct the online electrochemical corrosion test.The influence of WRH sizes on local corrosion of welded joints was studied at different flow rates.The electrochemical signals of the local corrosion of X80 welded joints at different flow rates were monitored in real time using electrochemical impedance spectroscopy and wire beam microelectrode.In addition,the corrosion products composition and properties were analyzed.The results show that the micro-turbulent flow fields induced by the WRHs can enhance ion mass transfer near the welded joints.The corrosion products on the WRH surface also present different microscopic morphologies at different flow rates.In strong flow fields,the locally enhanced wsS can peel off the dense corrosion product partially,leading to the electrochemical distribution of large cathode and small anode,which accelerates the occurrence and development processes of the local corrosion of welded joints.The scientific guidelines for the corrosion protection of long-distance oil and gas pipelines can be potentially provided.

(Molecular Plant 14,1539–1553;September 62021)In Figure 4G,we showed the root apical meristem lengths of different genotypes.However,because of inappropriate use of the software Adobe Illustrator(AI)and the high degree of similarity between the pictures,we mistakenly kept the picture of Col-0(panel of 50μM Pi),which was set as an object of reference in a lower layer for all the other panels for typesetting purposes and should have been deleted after typesetting,in the position of cry1cry2 mutant.A similar mistake also happened in Figure S15,in which we kept the GUS staining picture of line#3(panel of pLPR1::GUS/hy5)in the position of line#8.The wrong pictures in these two figures have been substituted with correct pictures in the figure below.The authors sincerely apologize for the mistakes.
