目的:分析竞技健美操运动员落地动作的生物力学特征,比较优势侧和非优势侧生物力学指标的偏侧性,探究影响落地稳定性的关键偏侧性因素。方法:以26名高校女性健美操运动员为研究对象,同步采集40 cm高台垂直双脚落地动作中的下肢运动学和动力学数据,比较优势侧和非优势侧的触地时刻关节角度、关节活动度(ROM)、地面反作用力(GRF)、负载率、压力中心(COP)位移和包络面积的差异,计算对称指数(代表偏侧性),并采用多元逐步回归方法分析指标偏侧性和COP包络面积的关系。结果:与非优势侧相比,优势侧在触地时刻具有更大的膝外旋和髋外展角(P<0.05),在落地过程中具有较大的踝屈伸、髋屈伸、髋内收-外展及较小的踝旋转ROM(P<0.05);优势侧的伸膝力矩峰值大于非优势侧(P<0.01);垂直方向负载率和伸膝力矩峰值的对称指数与COP包络面积呈显著正相关(P<0.05);垂直方向负载率、伸膝力矩峰值和膝关节旋转角度的对称指数可以解释COP包络面积差异的83.6%。结论:竞技健美操运动员落地动作存在肢体间的偏侧性,垂直方向负载率和伸膝力矩峰值的偏侧性越大,则落地稳定性越差。此外,垂直方向负载率、伸膝力矩峰值和膝关节旋转角度的对称指数可以作为落地稳定性的预测因子。

佛教通过翻译在传入吐蕃过程中,汲取了苯教的部分教义,形成了具有藏族文化特色的藏传佛教。藏传佛教在迅速发展过程中推崇佛经翻译事业起到了重要的推动作用。新时代时期,积极推进藏传佛教中国化是藏传佛教健康传承的必经之路。在坚持藏传佛教中国化方向进程中,加强汉藏翻译,一方面使藏传佛教教义教规的翻译呈现社会主义发展内涵,适应社会主义社会的时代要求。另一方面引进宗教中国化的理论,以社会主义核心价值观为引领,使藏传佛教浸润中国特色,弘扬先进思想。

根据《西藏王臣记》等史书记载,帕竹政权的第一任第悉大司徒绛曲坚赞为了稳固政权,促进发展,采取了减轻差税、改定法律、在各冲要地点兴建以内邬栋孜为首的城堡(宗)、设立宗谿等一系列制度。关于他所修建的城堡(宗),后人习惯称之为“大司徒的十三大宗”,但相关文献资料中几乎找不到“十三大宗”这样确切数字的表述。因此,对所谓“大司徒的十三大宗”的说法有待进一步考证,并且对于一些史书及论文中出现的琼杰宗、白朗伦珠孜宗、江噶尔达孜宗等类属于“大司徒的十三大宗”的说法更有待于进一步商榷。

Herein,the evolution of long-period stacking ordered(LPSO)phases in the as-cast Mg-6Gd-1Zn-0.6Zr(wt.%)alloy are investigated via transmission electron microscopy(TEM)and atom probe tomography(APT).The TEM results reveal that two types of LPSO phase(a bulky interdendritic phase and a plate-like matrix LPSO phase)are formed in the as-cast *** of the LPSO phases are confirmed to be of the 14H type,with a smaller proportion being of the 18R ***,the APT results reveal that the composition of the interdendritic LPSO phase is closer to that of the ideal 14H phase compared to the matrix LPSO phase,and both the interdendritic and matrix LPSO phases exhibit a Gd/Zn ratio of 2.5,thereby indicating a deficient Zn content compared to the ideal 14H phase(i.e.,1.3).In addition,the influence of the LPSO phases on the deformation behavior is investigated at different compressive plastic strains using electron backscatter diffraction(EBSD)analysis to reveal twinning and slip behavior during *** results indicate that the LPSO phase induces additional work hardening in the late stage of deformation via the suppression of{1011}compressive twinning and the activation of non-basal slip systems.

目的探讨血清同型半胱氨酸(Hcy)、低密度脂蛋白胆固醇(LDL-C)及糖化血红蛋白(HbA1c)在2型糖尿病视网膜病变(DR)中的影响。方法回顾性分析2019年4月—2022年6月本院内分泌科住院的2型糖尿病患者有糖尿病视网膜病变组(DR组)患者150例和非糖尿病视网膜病变(NDR组)患者150例的临床资料,包括每位患者的一般资料、生化指标。比较两组间的一般信息;分析DR组与NDR组的影响因素;多元素回归分析DR的危险因素。结果DR及NDR组患者年龄、病程方面差距具有统计学意义(P<0.05)。DR组患者Hcy、FBG、TG、LDL-C、HbA1c水平明显高于NDR组(P<0.05)。Pearson相关系数分析,DR组患者的Hcy与年龄,病程FBG、TG、TC、LDL-c、HbA1c呈正相关关系(P<0.05)。Logistics回归分析结果显示病程、TG、LDL-c、Hcy、HbA1c均是影响2型糖尿病视网膜病变的独立因素(P<0.05)。结论Hcy、LDL-c、HbA1c水平在DR患者中远高于NDR患者,三者与DR发生、发展存在一定联系,临床可根据其表达水平对患者病情变化进行有效评估。
