Journal of Acupuncture and Tuina Science 2014年第4期12卷 230-235页

作者： Wang sai-na Sheng Feng Pan Yun-hua Xu Feng Wang Zhi-chao Cheng Lei Han Chou-ping Tuina Department Longhua HospitalShanghai University of Traditional Chinese Medicine

Objective: To observe the clinical effect of tuina combined with auricular point sticking on cervical radiculopathy and evaluate in health economics. Methods: Using randomized single-blind controlled clinical design, a total of 72 cases with cervical radiculopathy were randomly allocated into an observation group or a control group by the ratio of 1:1, 36 in each group. Cases in the observation group were treated with tuina combined with auricular point sticking, whereas cases in the control group were treated with tuina alone. Then the clinical effects in the two groups were observed and the cost of health economics was evaluated. Results: The drop-out, recovery, improvement and failure cases, recovery rate and total effective rate in the observation group were 1, 15, 20, 0, 42.9% and 100% respectively, versus 2, 6, 23, 5, 17.6% and 85.3% in the control group, showing significant differences in recovery rate and total effective rate(Pna alone, tuina combined with auricular point sticking can obtain better effect and lower cost in health economics for cervical radiculopathy.

“两个结合”指导当代中国把马克思主义基本原理与中国具体实际、与中华优秀传统文化相结合,形成中国特色社会主义的新文化形态。在全面建设社会主义现代化强国的历史新时期,中国教育须担负起新文化形态建设的重要使命。但是,现有相关研究总量较少,且普遍成文较早,对当前而言针对性不足。本文聚焦当下,探讨中国教育履行中国特色社会主义新文化形态建设使命的重点内容与实践方法。基础教育和高等教育作为中国教育的主要阶段,应在坚持“两个结合”的同时发挥自身优势。建立和完善学科专业和课程教学体系,培养担负中华民族文化使命的时代新人;培育和弘扬社会主义核心价值观,加强中华民族现代文明教育;推动国家间的文化交流互鉴,吸收世界文明的优秀成果。用高质量的教育引领和推动中国特色社会主义文化的传承、发展和创新,推动建设社会主义文化强国。

感音神经性聋(sensorineural hearing loss,SNHL)是由于内耳与听觉皮层之间的听觉通路一个或多个部分的功能障碍而导致的常见临床疾病。其发病机制包括局部缺氧缺血、病毒感染以及微创伤等,但具体的病理机制仍不清楚。免疫和炎症介导的内耳疾病被认为是导致SNHL的机制之一,并且抗炎和免疫治疗对部分SNHL的听力恢复有效。此外,糖皮质激素治疗SNHL在临床上广泛应用,其可能机制包括抗炎作用,但具体机制尚不清楚。本文综述内耳免疫/炎症反应在SNHL,主要是噪声性耳聋、突发性耳聋、感染性聋、老年性聋和自身免疫性内耳病的病理生理学中的作用,以及免疫/炎症介导的SNHL的治疗。将免疫/炎症因子和免疫细胞(特别是巨噬细胞)作为治疗靶点,综述调节内耳免疫系统以修复组织并改善SNHL患者听力可能的干预措施。

针对空间自动对接靠拢段的相对位置控制问题,在分析滑模变结构控制的基本原理和设计方法的基础上提出了多模态滑模变结构控制方法。所谓的"多模态",指的是设计由s(0)=0与若干个s(0)≠0"滑模"区连接而成的"滑模运动"路径,使系统状态点沿着所设置的路径,从一个"模态"运动到另一个"模态",最终趋近目标点。详细阐述了多模态滑模变结构控制法的个体切换面设计、切换面的连接和控制律的设计;设计对接进展过程减弱对接状态变量间的耦合,以比较的方式,对多模态滑模变结构控制法、比例微分(PD)控制法和传统滑模变结构控制法的控制效果和性能进行了仿真和验证。仿真结果表明,多模态滑模控制系统具有良好的动态品质和性能,对变轨速度需求小,不仅能减少燃料的损耗,而且可以人为控制状态轨迹,实现状态轨迹的多样化。
