网联车辆协同巡航系统快速滚动时域状态估计

考虑云平台监控下的网联车辆协同自动巡航控制(CACC)系统,提出一种快速滚动时域估计方法.采用网联车队纵向动力学模型描述网联车辆CACC系统,降低网联车辆CACC系统的状态能观性要求.再应用块概念设计滚动时域估计算法的噪声块结构,压缩滚动时域估计问题的优化变量个数,从而减少其在线计算量.进一步,应用李雅普诺夫稳定性定理证明估计误差系统的渐近稳定性.最后以5车网联车队系统仿真验证所提算法的有效性.

肢端推拿技术治疗颈型颈椎病临床研究

目的:观察肢端推拿技术治疗颈型颈椎病的临床疗效。方法:选取本院2016年1月至2017年6月收治并确诊的颈型颈椎病患者60例,随机分为治疗组和对照组,每组30例。治疗组给予肢端推拿技术治疗,对照组给予西乐葆口服治疗。观察两组患者视觉模拟评分法(visual analogue scale,VAS)、颈椎功能障碍指数量表(neck disability index,NDI)等指标,评价其临床疗效及安全性。结果:两组患者治疗4周后VAS评分、NDI评分优于对照组,差异有统计学意义(P<0.05);治疗组有效率86.67%,对照组有效率70.00%,治疗组优于对照组,差异有统计学意义(P<0.05)。结论:肢端推拿技术治疗颈型颈椎病疗效显著,能有效缓解颈型颈椎病患者疼痛症状,改善颈型颈椎病患者NDI指数。

脊柱微调手法结合牵引治疗神经根型颈椎病的随机对照研究

目的:本研究从视觉模拟标尺(Visual Analogue Scale,VAS)及颈椎功能障碍指数量表(Neck Disability Index,NDI)的角度,观察脊柱微调手法结合牵引治疗神经根型颈椎病(Cervical Spondylotic Radiculopathy,CSR)的临床疗效,探索治疗CSR的更优方法。方法:将96例神经根型颈椎病患者随机分为脊柱微调手法结合牵引组(治疗组)48例和传统推拿手法结合牵引组(对照组) 48例;将两组治疗前后的VAS评分、NDI指数及临床疗效进行比较。结果:治疗4周后,治疗组总有效率为95.83%,对照组总有效率为81.25%,两组患者较治疗前VAS评分、NDI指数评定均有显著改善(P<0.01),而治疗组较对照组改善更为显著(P<0.05)。结论:脊柱微调手法结合牵引治疗神经根型颈椎病方法安全、疗效确切,相关指标均明显优于对照组,具有很好的临床推广价值。

传统推拿联合普通针刺治疗青少年假性近视临床疗效观察

目的:观察传统推拿联合普通针刺治疗青少年假性近视的临床疗效,探讨治疗青少年假性近视的更优方法。方法:将120例青少年假性近视患者随机分为观察组和对照1组、对照2组各40例,观察组给予传统推拿联合普通针刺治疗,对照1组给予单纯传统推拿治疗,对照2组给予单纯普通针刺治疗,观察三组裸眼视力及临床疗效。结果:观察组总有效率为95.00%,显著高于对照1组、对照2组的75.00%、72.50%(P<0.05);观察组裸眼视力改善程度显著优于对照1组、对照2组(P<0.05)。结论:传统推拿结合普通针刺疗法可有效提高治疗近视的临床疗效,改善患者的视力,且该疗法操作简单、疗效确切,值得临床推广应用。

Ginger-partitioned moxibustion plus pediatric massage for treating infantile diarrhea due to spleen deficiency:a randomized controlled clinical trial

Objective:To observe the clinical efficacy of ginger-partitioned moxibustion plus pediatric massage(tuina)in treating infantile diarrhea due to spleen deficiency.Methods:Ninety infants were randomly divided into a massage plus moxibustion group,a massage group and a drug group by the random number table method,with 30 cases in each group.The intervention was conducted for two consecutive courses.The infants in the massage plus moxibustion group were treated with pediatric massage and ginger-partitioned moxibustion at Shenque(CV 8).The infants in the massage group were treated with pediatric massage alone,while those in the drug group were treated with smecta.The primary and secondary symptom scales were assessed before and after treatment and at the follow-ups,and the total effective rate was evaluated after treatment.Results:The total effective rate in the massage plus moxibustion group was significantly different from that in the massage group and drug group(both P<0.05).After treatment,the scores of primary and secondary symptoms decreased in all three groups,with statistically significant intra-group differences(all P<0.05);the scores of primary symptoms were significantly different between the massage plus moxibustion group and the drug group(P<0.05);the scores of secondary symptoms in the massage plus moxibustion group and the massage group were significantly different from that in the drug group(both P<0.05).The differences in the time to recover normal bowel movement frequency among the three groups were not statistically significant(P>0.05).Conclusion:Ginger-partitioned moxibustion plus pediatric massage compared with pediatric massage or smecta monotherapy shows superior clinical efficacy in treating infantile diarrhea due to spleen deficiency,and has the advantages of appetite improvement,physique strengthening and short course.
