AIM: To investigate the impact of enteral nutrition(EN) on the body composition and metabolism in patientswith Crohn's disease(CD). METHODS: Sixty-one patients diagnosed with CD were enrolled in this study. They were given only EN(enteral nutritional suspension, TPF, non-elemental diet) support for 4 wk, without any treatment with corticosteroids, immunosuppressive drugs, infliximab or by surgical operation. Body composition statistics such as weight, body mass index, skeletal muscle mass(SMM), fat mass, protein mass and inflammation indexes such as C-reactive protein(CRP), erythrocyte sedimentation rate(ESR) and CD activity index(CDAI) were recorded before and after EN support. RESULTS: The 61 patients were divided into three groups according to CDAI before and after EN support: A(active phase into remission via EN, n = 21), B(remained in active phase before and after EN, n = 19) and C(in remission before and after EN, n = 21). Patients in group A had a significant increase in SMM(22.11 ± 4.77 kg vs 23.23 ± 4.49 kg, P = 0.044), protein mass(8.01 ± 1.57 kg vs 8.44 ± 1.45 kg, P = 0.019) and decrease in resting energy expenditure(REE) per kilogram(27.42 ± 5.01 kcal/kg per day vs 22.62 ± 5.45 kcal/kg per day, P < 0.05). There was no significant difference between predicted and measured REE in active CD patients according to the HarrisBenedict equation. There was no linear correlation between the measured REE and CRP, ESR or CDAI in active CD patients. CONCLUSION: EN could decrease the hypermetabolism in active CD patients by reducing the inflammatory response.

设计了一种遥操作护理机器人系统,为实现从端同构式机器人的随动运动控制,对主端操作者人体姿态解算方法进行了研究.首先,构建由惯性传感单元构成的动作捕捉系统,对用作从端机器人动作指令的操作者人体姿态信息进行采集,采用四元数法对人体运动原始数据进行初步求解.其次,将四元数法得到的姿态数据解算成依据仿人结构设计的护理机器人各关节运动的目标姿态角,实现人体姿态到机器人动作的同构性映射.最后,为验证本文所提姿态解算方法的性能,设计了操作者控制护理机器人完成递送和拿取药瓶动作的实验.结果表明,本文姿态解算方法的解算性能与参考系统基本相同;在操作者动作姿态快速变化的时间段,系统仍可获得较高精度的目标姿态数据,其误差在动态条件下依旧能保持在2%以下;护理机器人可较好地实时复现操作者的人体动作.本文方法能满足机器人进行一般护理作业时对人体姿态数据处理的快速性和准确性要求.

从乾隆五十五年起的日渐式微,到光绪二十八年出现复兴,再到民国九年走向衰亡,是传奇杂剧终结消亡的三部曲;五四新文化运动以后,传奇杂剧失去了存在的必要和可能,表明它已到了走向消亡的历史时刻;近现代各种新旧文学样式的外部挤压和多重影响,使传奇杂剧的生存空间愈来愈小;而近现代以来主流文化的逼进与围困,也大不利于传奇杂剧的生存。这种内外夹击和内忧外患,使传奇杂剧陷入了极其艰难的境地并只能走向消亡。这反映了中国传统文学艺术在新的文化氛围中的无法适应和生命力的丧失,反映了中国传统文化在学习西方、走向现代之际的必然命运。

闸坝建设和运行必然引起河流水文情势自然状态改变,并对河流生态系统产生影响,因此,开展闸控河流生态需水调控研究对河流生态修复和改善具有重要意义。基于河流水文情势变化对河流生态系统影响分析,提出了基于水文情势需求的河流生态需水计算模式;以河流生态系统恢复为目标,综合考虑河流生态和经济社会用水需求,构建了考虑自然水流情势的闸坝生态需水调控多目标模型;采用多方案模拟技术方法,分析了不同闸坝调控方式下的河流生态需水方案。结果表明,考虑生态需水的"天然水流模式目标最大"调控方式,比经济社会用水优先的"水量分配目标最大"调控方式,对河流水文情势关键指标的改善作用更加明显,更有利于河流生态系统健康发展。

在20℃下连续运行厌氧膨胀颗粒污泥床(EGSB)反应器,对其处理模拟啤酒废水的工艺运行、污泥特性及微生物种群结构进行研究,结果表明:①HRT为18 h,经184 d的运行,EGSB反应器的有机负荷(以COD计)可达10 kg/(m3.d),COD去除率为85%以上,去除1 kg COD可产沼气0.58 m3;②随有机负荷逐渐提高,颗粒污泥粒径逐渐增大,沉降性能逐渐提高,但当负荷达到10 kg/(m3.d)时,颗粒污泥平均粒径有变小趋势;与中温厌氧污泥相比,低温污泥的胞外多聚物(ECP)总量有较大增加,其中蛋白质含量增加明显;③与接种污泥相比,在20℃下运行不同时期污泥中产甲烷菌的种类未发生明显变化,但接种同样颗粒污泥在15℃下运行6个月后污泥中的优势产甲烷菌种发生了明显的变化.

Background： Many studies have reported that depression and anxiety have bidirectional relationship with headache. However, few researches investigated the roles of depression or anxiety in patients with headache. We surveyed the prevalence of depression and anxiety as a complication or cause of headache among outpatients with a chief complaint of headache at neurology clinics in general hospitals. Additional risk factors for depression and anxiety were also analyzed. Methods： A cross-sectional study was conducted at 11 general neurological clinics. All consecutive patients with a chief complaint of headache were enrolled. Diagnoses of depression and anxiety were made using the Chinese version of the Mini International Neuropsychiatric Interview, and those for headache were made according to the International Classification of Headache Disorders, 2＇ld Edition. The headache impact test and an 11-point verbal rating scale were applied to assess headache severity and intensity. Logistic regression was used to analyze risk factors of patients with headache for depression or anxiety. Results： A total of 749 outpatients with headache were included. Among them, 148 （19.7%） were diagnosed with depression and 103 （13.7%） with anxiety. Further analysis showed that 114 （15.2%） patients complaining headache due to somatic symptoms of psychiatric disorders and 82 （10.9%） had a depression or anxiety comorbidity with headache. Most patients with depression or anxiety manifested mild to moderate headaches. Poor sleep and severe headache-related disabilities were predictors for either depression or anxiety. Conclusion： Clinicians must identify the etiology of headache and recognize the effects of depression or anxiety on headache to develop specific treatments.
