目的:探讨益气活血汤联合艾灸对四肢骨折术后气虚血瘀证患者的影响。方法:选取四肢骨折术后气虚血瘀证患者,随机分为对照组和观察组,每组60例,均连续治疗14 d。对照组接受常规康复治疗,观察组在对照组基础上联合益气活血汤和艾灸治疗。比较两组患者治疗前后的中医证候积分、患肢功能恢复情况、患肢肿胀度、骨代谢状态、凝血功能及并发症发生率。结果:治疗后,观察组患者中医证候评分各项数值低于对照组(均P<0.05)。观察组患者四肢功能恢复理想率高于对照组,观察组活化部分凝血活酶时间、凝血酶原时间、凝血酶时间长于对照组,差异有统计学意义(均P<0.05)。观察组骨碱性磷酸酶、骨钙素、碱性磷酸酶水平高于对照组,而Ⅰ型胶原羧基端肽低于对照组,差异有统计学意义(均P<0.05)。观察组术后相关并发症总发生率低于对照组,差异有统计学意义(P<0.05)。结论:益气活血汤联合艾灸治疗四肢骨折术后气虚血瘀证可有效改善患肢功能恢复状况,加速抗凝血作用,促进术后患者恢复,减少相关并发症发生。

以吡虫啉废水为研究对象,通过对COD、氨氮、TP以及吡虫啉去除效率的分析,并结合XPS及宏基因组测序结果,探究了玉米秸秆生物炭土地渗滤系统对吡虫啉废水的处理效能及微生态。结果表明,在该土地渗滤系统运行前期(1~14 d),COD去除率在55%~80%间波动;经过适应期后,氨氮去除率由1~11 d时的19.14%提升为31~39 d的26.39%;TP的平均去除率由55.40%提升到72.03%;且在进水吡虫啉浓度为10 mg/L的情况下,该系统对吡虫啉的平均去除率为96.71%。Proteobacteria、Actinobacteria、Bacteroidetes为该系统中门水平下的优势菌群,属水平下Enterobacter占比最大(55.6%)。在糖酵解过程中甘油醛-3-磷酸脱氢酶(gap2)含量为0,推测吡虫啉会使gap2对溶解氧较为敏感;氨氧化过程的关键酶氨单加氧化酶(AMO)和羟胺脱氢酶(Hao)的功能基因并未检测出,说明该系统中氨氧化微生物的活性受到抑制;整个戊糖磷酸循环中的每一步均检测出相应作用酶的功能基因,说明吡虫啉的添加不会对该系统中微生物的戊糖磷酸循环产生不利影响。

结缔组织病(CTD)是一组累及全身结缔组织的自身免疫疾病。间质性肺病(ILD)是CTD常见的肺部并发症。结缔组织病相关肺间质病的预后不一,部分患者通过治疗,ILD的影像学改变逆转;部分患者ILD病变无法逆转,但可长期维持稳定;还有部分患者虽经积极治疗,ILD仍持续进展,最终发展为呼吸衰竭。因此全面了解结缔组织病相关肺间质病(CTD-ILD)的进展倾向对于制定个体治疗方案及改善患者的预后具有重大的意义。文章就关于结缔组织病相关肺间质病进展倾向的研究现状进行综述。

目的了解HIV/AIDS手术患者住院费用构成及影响因素,为合理控制住院费用,优化医疗服务价格体系提供参考。方法收集南通市艾滋病定点医院2017年1月1日-2021年12月31日的316例HIV/AIDS手术患者住院病案首页信息,对患者的住院费用构成进行描述性分析,并采用通径分析探讨其住院费用的影响因素。结果HIV感染者和AIDS手术患者分别为236人(74.7%)和80人(25.3%),住院天数中位数为10天和21天,住院费用中位数为16690.7元和36251.2元;5年HIV/AIDS手术患者次均费用28383.8元,年均费用复合增长率为6.1%,且AIDS患者的住院天数和费用均高于HIV感染者,差异具有统计学意义。住院费用的主要构成为耗材类(32.4%)、药品费用(27%)、诊断类(18.6%)。通径分析结果显示住院天数是住院费用的主要影响因素,性别、年龄、疾病种类不仅对住院费用存在直接效应,还通过住院天数间接影响住院费用,不同疾病阶段通过住院天数间接影响住院费用。结论HIV/AIDS手术患者住院费用呈增长趋势,费用构成中耗材类与药品费占比较大,影响住院费用的首要因素为住院天数,AIDS患者的住院天数和费用均高于HIV感染者,差异具有统计学意义。医疗机构应加强对可控因素的管理,以缩短住院天数为重点,切实减轻患者经济负担。

It appears very interesting and particularly useful to perform DEM reconstruction with the configuration of multichannel bistatic SAR(Bi SAR) because of its considerable advantages. In typical processing flow of multichannel interferometric synthetic aperture radar(In SAR), techniques based on statistical methods or iterative methods does not work very well with limits of specific Bi SAR configurations. Moreover, the tradeoff between the correctness and precision of the reconstruction of different baselines needs to be overcome as *** on the advantages of multichannel Bi SAR configuration, basic idea is the joint utilization of amplitude data, iterative reconstruction results and ML results to help the optimization of the total MRF energy ***, a multichannel DEM reconstruction method based on Markov Random Fields(MRFs) for Bi SAR, which concerns much about discontinuities and energy functions, is proposed to achieve not only correct but also more precise results. Afterward, the strategy to determine the weight parameter and processing flow is ***, simulated and real data experiments are given to validate the proposed method.
