目的:运动干预被认为是前交叉韧带重建后康复的基础。然而,关于何种运动疗法在改善前交叉韧带重建后患者膝关节肌肉力量和功能方面更有效,目前仍未得出明确结论。为此,文章采用网状Meta分析方法,比较运动疗法治疗前交叉韧带重建后的疗效,为选择最佳运动疗法提供循证医学依据。方法:计算机检索PubMed,Web of Science,Embase,The Cochrane Library及EBSCO数据库运动疗法治疗前交叉韧带重建后的随机对照试验,检索时限均从建库至2023-11-20。结局指标包括股四头肌肌力、腘绳肌肌力、膝关节功能评分3个连续性变量。运用EndNote X9.1软件筛选文献。采用Cochrane风险偏倚评估工具对纳入的文献进行质量评价,根据GRADE评分对文章结果的证据强度进行评级,采用Stata 16.0进行网状Meta分析。结果:①共纳入36项随机对照试验,包括1179例前交叉韧带重建后患者,纳入文献整体质量中等;涉及9种运动疗法:等速训练、交叉训练、离心训练、水中康复、血流限制训练、运动控制训练、增强式训练、全身振动训练和综合训练;对照措施为常规康复训练。②网状Meta分析结果显示:与常规康复训练相比,离心训练(SMD=2.08,95%CI:0.56-3.60,P=0.007)对前交叉韧带重建后患者股四头肌肌力的改善效果最佳,其次是综合训练(SMD=1.69,95%CI:0.11-3.27,P=0.249)和全身振动训练(SMD=0.81,95%CI:0.11-1.51,P=0.042);在提升患者腘绳肌肌力方面,综合训练(SMD=2.08,95%CI:0.30-3.86,P=0.022)效果最佳,其次是增强式训练(SMD=1.51,95%CI:0.18-2.84,P=0.026)和等速训练(SMD=1.37,95%CI:0.06-2.67,P=0.039);综合训练(SMD=4.60,95%CI:2.40-6.80,P<0.001)改善膝关节功能评分最有效,其次是离心训练(SMD=1.75,95%CI:0.24-3.25,P=0.023)和水中康复(SMD=1.65,95%CI:0.07-3.24,P=0.041)。结论:低到中等强度的临床证据证实,在改善前交叉韧带重建后患者膝关节肌肉力量和功能方面,综合训练可能是最有效的运动疗法,其次是离心训练、增强式训练、等速训练、全身振动训练、水中康复。未来仍需更多高质量的临床随机对照试验来验证结论的可靠性。

Comparison of the effects of soil moisture and El Nino on summer precipitation in eastern China

引用

Science China Earth Sciences 2020年第2期63卷 267-278页

作者： juan ZHOU Zhiyan zuo Xinyao RONG State Key Laboratory of Severe Weather Chinese Academy of Meteorological Sciences

The effects of spring soil moisture over the vast region from the lower and middle reaches of the Yangtze River valley to North China(YRNC) and El Ni?o on the East Asian summer monsoon(EASM) and precipitation in eastern China, as well as the relevant mechanisms, are investigated using the modified atmospheric model ECHAM5 coupled with the Common Land Model. These models are the atmospheric and land components of the climate system model developed at the Chinese Academy of Meteorological Sciences(CAMS-CSM). The simulations show that both soil moisture anomalies in eastern China and El Ni?o sea surface temperature(SST) anomalies have significant influences on the EASM, with the effect of soil moisture being slightly greater than that of the El Ni?o. However, the impacts of soil moisture on EASM and rainfall in eastern China are markedly different from those of the El Ni?o. Wetter(drier) soil over the YRNC corresponds to less(more) precipitation over northern and southeastern China, and more(less) precipitation over the Yangtze River basin and northeastern China, as well as a strengthened(weakened) and westward-shifted(eastward-shifted) West Pacific Subtropical High and a deepened(shallower) East Asian trough, representing a weakened(strengthened) EASM pattern. During El Ni?o developing summers, an anomalous anticyclone extends from northeastern to northern China, and an anomalous cyclone occupies the middle and lower reaches of the Yangtze River and southern China. Concurrently, the West Pacific Subtropical High is anomalously weaker than normal. As a result,rainfall anomalously increases over the lower reaches of the Yangtze River and southern China, and decreases over northern and northeastern China. In El Ni?o decaying summers, there is an anomalous cyclone over northeastern China and an anomalous anticyclone over southern China. The convergence of southerly airflow and northerly winds leads to enhanced rainfall around northern China and the middle reaches of the Y

Direct solution for fixed source location using well-posed TDOA and FDOA measurements

引用

Journal of Systems Engineering and Electronics 2020年第4期31卷 666-673页

作者： LIU Congfeng yun Jinwei SU juan Research Institute of Electronic Countermeasure Xidian UniversityXi’an 710071China

Based on the time differences of arrival(TDOA) and frequency differences of arrival(FDOA) measurements of the given planar stationary radiation source, the joint TDOA/FDOA location algorithm which solves the location of the target directly is proposed. Compared with weighted least squares(WLS) methods,the proposed algorithm is also suitable for well-posed conditions,and gets rid of the dependence on the constraints of Earth's surface. First of all, the solution formulas are expressed by the radial range. Then substitute it into the equation of the radial range to figure out the radial range between the target and the reference station. Finally use the solution expression of the target location to estimate the location of the target accurately. The proposed algorithm solves the problem that WLS methods have a large positioning error when the number of observation stations is not over-determined. Simulation results show the effectiveness of the proposed algorithm, including effectively increasing the positioning accuracy and reducing the number of observatories.
