Background and Aims:Nonbiological artificial liver(NBAL)is frequently used as a first-line treatment for hepatitis B virus-associated acute-on-chronic liver failure(HBV-ACLF).This study aimed to compare the therapeutic efficacy and cost-effectiveness ratio(CER)of comprehensive medical treatment,plasma exchange(PE),and double plasma molecular adsorption system(DPMAS)plus half-dose PE(DPMAS+PE)in patients with ***:A total of 186 patients with HBV-ACLF randomly received comprehensive medical treatment,PE,or DPMAS+PE and were prospectively *** were divided into four subgroups based on the pretreatment prothrombin activity(PTA):Group I(PTA>40%),group II(PTA 30–40%),group III(PTA 20–30%),and group IV(PTA<20%).The main outcome measures were 28 day effectiveness;90 day liver transplantation-free survival;change of biochemical parameters;and ***:DPMAS+PE treatment was associated with significantly higher 28 day effectiveness and 90 day liver transplantation-free survival compared with PE treatment in patients with group I liver *** of serum total bilirubin(TBIL),AST,and creatinine(Cr)were significantly higher in the DPMAS+PE group than in the PE *** subjects with group I liver failure,DPMAS+PE treatment had advantages of lower CER values and better ***:Compared with comprehensive medical treatment and PE alone,DPMAS with halfdose sequential PE treatment more effectively improved TBIL,AST,and Cr in HBV-ACLF patients,improved 28 day effectiveness and 90 day survival rates in patients with group I liver failure,and was more cost ***+PE is a viable NBAL approach for treatment of HBV-ACLF.

为解决5G网络中各类应用差异性大对通信需求侧重点不同造成的网络资源利用率低的问题,提出一种基于联合优化的网络切片资源分配策略,旨在通过综合考虑切片间资源分配和切片内资源调度问题,最大化网络资源利用率和网络收益。首先,在切片间资源分配问题中定义一个切片用户平均满意度函数,基于切片用户数量、切片调度时延以及切片优先级等约束,提出基于用户服务质量(Qo S)的比例公平资源分配算法,以权衡各切片之间的公平性和用户需求。其次,在切片内资源调度问题中引入服务降级和资源迁移函数,针对拥塞和非拥塞2种情况为内部接入用户和外部接入用户分别建立价格模型。基于所提价格模型建立基站与用户之间的Stackelberg博弈,并采用一种低复杂度的全局搜索算法求解该博弈的最佳响应,使基站效用和用户效用最优。仿真结果表明,所提策略能够有效提高资源利用率和网络收益,并降低网络拥塞,较好地实现资源分配的公平性。

以自制的高纯硫酸镁和由氨水、氢氧化钠组成的复合碱液为原料制备高纯纳米氢氧化镁粉体。考察几种关键因素对镁沉淀率和产物平均粒度的影响。结果表明,随着溶液中Mg2+初始浓度和反应温度的提高,镁沉淀率提高,产物平均粒度先降低后提高;延长反应时间和陈化时间,镁沉淀率和产物平均粒度都提高;提高搅拌速度,镁回收率提高不大,但产物平均粒度减小。当Mg2+初始浓度2.0mol·L-1,反应温度50℃,反应时间60min,搅拌速度900r·min-1,陈化时间90min时,Mg沉淀率为95.4%,得到的氢氧化镁粉体为六方片状颗粒,粒度在50～140nm,且粒度分布均匀,分散性好,纯度很高。
