BACKGROUND Direct-acting antivirals(DAAs)revolutionized the treatment of chronic hepatitis C virus(HCV)-associated disease achieving high rates of sustained virological response(SVR).However,whether DAAs can reduce the occurrence of hepatocellular carcinoma(HCC)in patients with HCV-associated cirrhosis who are at high risk have not been concluded.AIM To investigate the effect of DAAs on the occurrence of HCC in patients with HCVassociated cirrhosis after achieving SVR.METHODS Of 427 inpatients with HCV-associated cirrhosis were enrolled in Tianjin Second People's Hospital from January 2014 to April 2020.118 patients weren’t received antiviral treatment with any reasons named non-antiviral treatment group,and 236 patients obtained from the 309 DAAs treatment patients according to the propensity score matching named DAAs treatment group.Demographic information and laboratory data were collected from baseline and the following up.Kaplan-Meier curve and Log-Rank test were used to compare the incidence and cumulative incidence of HCC between the two groups.Cox proportional risk regression was used to re-evaluate the risk factors for HCC.RESULTS HCC incidence was 4.68/100PY(95%CI,3.09-6.81)in the DAAs treatment group,while it was 3.00/100PY(95%CI,1.50-5.37)in the non-antiviral treatment group,and the relative risk was 1.82(95%CI,0.93-3.53,P>0.05).The incidence of HCC at 12,24,36 and 48 months was 3.39%,6.36%,8.47%and 10.17%in the DAAs treatment group,and it was 0%,0%,3.39%and 9.32%in the non-antiviral treatment group,respectively.Age>58[hazard ratio(HR)=1.089;95%CI,1.033-1.147;P=0.002]and liver stiffness measurement>27.85 kPa(HR=1.043;95%CI,1.022-1.065;P=0.000)were risk factors for HCC in all patients(n=427),and DAAs treatment didn’t show protective efficacy.CONCLUSION DAAs treatment seems failed to reduce the incidence of HCC occurrence in HCV-associated cirrhosis in 48 months,and even increased the incidence of HCC in 36 months.

As the range of applications for molybdenum and its alloys has expanded,the corrosive environment for molybdenum alloys has become more demanding.In the past,the content of doping elements has been studied to investigate their infl uence on the corrosion performance of titanium–zirconium–molybdenum(TZM)alloys.In this paper,it is considered that the second phase in the alloy is the main factor aff ecting the corrosion performance of TZM alloys.By comparing the corrosion behavior of molybdenum metal and TZM alloy,the eff ect of the secondary phase on corrosion behaviors of TZM alloy has been investigated.The results show that the second phase reduces the corrosion resistance of the TZM alloy.The potential of the second phase is 73.7 mV higher than that of the Mo matrix,which contributes to the formation of microscopic electric couples.Under the action of microscopic electric couples,pitting corrosion is preferentially formed at the interface between the second phase and the matrix,which accelerates the corrosion of the matrix.This paper provides a theoretical basis for the application of TZM alloys in corrosive environments.

Metal-organic framework-like materials（MOFs）have been developed in the fields of photocatalysis for their excellent optical properties and physicochemical properties,including environmental remediation,CO2 photoreduction,water splitting,and so on.With their important roles in various fields,rare earth elements have received growing interests from scientists.Modifying MOFs with rare earth elements for modification allows broadening the absorption spectrum,while the active electrons on their empty 4f orbitals can act as traps to capture photoexcited carriers to inhibit the recombination of electron-hole pairs,thus promoting photocatalytic activity.Therefore,rare earth elements modified MOFs provide an attractive way to achieve their high value utilization.In this mini-review,the synthesis of rare earth element-modified MOFs photocatalysts and corresponding applications in the removal of antibiotics,CO2reduction,and hydrogen production are constructively summarized and discussed.Finally,the latest advancements and current difficulties of these materials as well as the application prospects are also provided.

Background:Multiparous women are at a higher risk of gestational diabetes mellitus(GDM) than primiparas.Physical activity during pregnancy has been shown to be beneficial for GDM,but there is little evidence on the association between physical activity and glycemic control among women with GDM,whether primiparas or multiparas.Thus,the objective of the present study was to examine the association between physical activity and glycemic control in women with GDM and to determine what,if any,effects result from number of parous events.Methods:A prospective cohort of 1162 women with GDM was recruited,with 604 multiparas(51.98%).The general linear model was used to calculate the risk difference and its 95% confidence interval(95%CI) to quantify the impact of parous events on glycemic control in pregnancy as well as the association between physical activity time and glycemic control.Results:Among 1162 women with GDM,the median daily activity time was 65 mm(interquartile range(IQR):45-90 min),and the abnormal plasma glucose(PG) percentage,calculated as number of abnormal PG tests divided by the total number of PG tests,was 40.00%(IQR:22.22%-66.67%).The percentage of abnormal PG was stabilized and statistically lower with daily physical activity time exceeding 60 min among primiparas(IQR:30.89%-44.43%) and exceeding 90 min among multiparas(ranged from 27.76% to 38.82%).After adjusting for potential confoumders,primiparas tended to have a lower percentage of abnormal PG than do multiparas(rate difference=-0.39,95%CI:-3.61 to2.84).The same amount of physical activity time was significantly less effective for multiparas than for primiparas(trend p-value <0.01).Conclusion:In women with GDM,being multiparous is associated with less effective glycemic control through physical activity,such that multiparas need more physical activity to achieve glycemic control at a similar level to primiparas.

文章在中国人口老龄化加剧和总需求不足的背景下,借助CHIP2002年、2013年和2018年数据,基于不平等分解方法,对全国60岁及以上老年人口的消费差距进行分析。研究发现:(1)我国老年人口的消费差距呈下降趋势,但消费不平等问题依然突出,2018年全国老年人消费基尼系数为0.44。(2)消费差距主要表现为不同家庭结构、城乡和高低消费群体之间的消费水平和消费结构差异。(3)从消费结构看,我国老年人口主要以食品、居住和医疗保健消费为主,其中医疗保健和居住支出扩大了老年人口的消费差距,食品支出缩小了老年人消费差距;从消费水平看,我国老年人口的消费差距主要是收入差异、城乡差异和家庭结构差异导致的,2018年的贡献率分别为39%、9%和8%。本研究为理解中国老年人消费提供新认识,为扩大国内需求、激发“银发市场”活力、积极应对人口老龄化提供一个新视角。

Background:Ankle complex proprioceptive ability,needed in active human movement,may change from childhood to elderly adulthood;however,its development across all life stages has remained unexamined.The aim of the present study was to investigate the across-the-lifespan trend for proprioceptive ability of the ankle complex during active ankle inversion movement.Methods:The right ankles of 118 healthy right-handed participants in 6 groups were assessed:children(6-8 years old),adolescents(13-15 years old),young adults(18-25 years old),middle-aged adults(35-50 years old),old adults(60-74 years old),and very old adults(75-90 years old).While the participants were standing,their ankle complex proprioception was measured using the Active Movement Extent Discrimination Apparatus.Results:There was no significant interaction between the effects of age group and gender on ankle proprioceptive acuity(F(5,106)=0.593,p=0.705,η_p^2=0.027).Simple main effects analysis showed that there was a significant main effect for age group(F(5,106)=22.521,phan children,adolescents,old adults,and very old adults.The middle-aged group had levels of ankle proprioceptive acuity similar to those of the young adults.The scores for males and females were not significantly different.Examination of the range of the scores in each age group highlights the possible level that ankle complex movement proprioceptive

针对自主汽车队列与人工驾驶车辆混合的交通流问题,考虑汽车队列自身固有的动力学特性及其与交通流的耦合作用,研究了汽车队列固有动态特性的混合交通流特性。首先建立了自主汽车队列慢化概率与队列车辆的车头时距以及队列规模之间的关系模型,然后搭建了开放边界条件下汽车队列和人工驾驶车辆混合的元胞自动机交通流模型,最后进行了仿真分析。仿真结果表明,本文所建立的考虑汽车队列动态特性的混合交通流元胞自动机模型,揭示了现有模型无法反映的一些特殊的混合交通流特性;考虑汽车队列动态特性的混合交通流量会显著受到队列车头时距、队列规模等队列特征的影响,并且呈现出一定的非线性影响关系;车头时距和队列规模对混合交通流量的不利和有利影响同时存在,扩大队列规模和提高渗透率可显著改善混合交通流的流量特性,显著提升高车流密度下的道路通行能力。
