作者： Hou-cheng Liang Jing-Dong Zhang Pi-Fu Luo Ying Qiao An-Le su Ying Zhang Hong-Na Zhu Xi'an BRIGHT Eye Hospital Xi'an 710068 Shaanxi Province China Department of Ophthalmology the Second Affiliated Hospital of Xi'an Jiaotong University (Xibei Hospital) Xi'an 710002 Shaanxi Province China Shaanxi Provincial Eye Research Institute and Xi'an Eye Hospital Xi'an 710002 Shaanxi Province China Department of Anesthesiology University of Cincinnati College of Medicine Cincinnati 45267 OH USA Department of Pathology King Med Diagnostics Intemational Bioisland Guangzhou 510050 Guangdong Province China

AIM： To investigate a possible trigeminal proprioceptive- oculomotor neural pathway and explore possible synaptic connections between neurons in this pathway. Attempt to bring a new insight to mechanism of Marcus Gunn syndrome （MGS）. METHODS： Anterograde and retrograde tract tracing was applied and combined with immunofluorescent stain in rats. After electrophysiological identifying mesencephalic trigeminal nucleus （Vine） neurons, intracellular injection of tracer was performed to trace axon trajectory. REsuLTS： Following injections of anterograde tracers into the Vine, labeled terminals were observed ipsilateral in oculomotor and trochlear nuclei （Ill/IV）, as well as in their premotor neurons in interstitial nucleus of Cajal and Darkschewitsch nucleus （INC/DN）. Combining with choline acetyltransferase （CHAT） immunofluorescent stain, it showed that Vme projecting terminals contact upon ChAT positive Ill/IV motoneurons under confocal microscope. By retrograde labeling premotor neurons of the III, it showed that Vme neuronal terminals contact with retrogradely labeled pre-oculomotor neurons in the INCIDN. Axons of intraceiiularly labeled Vme neurons that respond to electric stimuli of the masseter nerve traveled into the ipsilateral III. CONCLUSION： There may exist a trigeminal propdoceptive- oculomotor system neural circuit in the rat, which is probably related to vertical-torsional eye movements. Possible association of this pathway with MGS etiology was discussed.

目的:慢性踝关节不稳临床上主要表现为肌无力、间断性疼痛和反复崴脚等症状,严重影响运动锻炼和日常生活。本体感觉缺失、腓骨反应时间延长和外翻力量减弱等可能是造成慢性踝关节不稳的主要原因,因此通过运动干预可以有效改善踝关节不稳相关症状。通过Meta分析定量评价平衡训练对慢性踝关节不稳康复干预的效果,为慢性踝关节不稳患者科学制定运动处方提供可靠的理论基础和实践依据。方法:检索中国知网、维普、Web of Science和PubMed数据库关于平衡训练对慢性踝关节不稳患者症状康复和动态平衡影响的随机对照试验文献,文献发表时间为各数据库建库至2022-11-23。包括2名评审人员依据物理治疗证据量表对纳入文献进行文献质量评估,主要结局指标为自我功能评分量表,次要结局指标为星形偏移平衡测试,均为连续性变量。采用RevMan 5.3和Stata-SE 15软件对纳入文献进行森林图绘制、Meta回归、亚组分析、敏感性分析和发表偏倚评价。结果:①共纳入18篇随机对照试验文献,包括慢性踝关节不稳患者641例。整体上文献的方法学质量较高。②Meta分析结果显示,平衡训练可以改善慢性踝关节不稳患者的功能康复效果(SMD=0.82,95%CI:0.41-1.23,P<0.0001)。Meta回归显示干预时间可能是产生异质性的主要原因(P=0.008)。③亚组分析结果显示,干预6周(SMD=0.98,95%CI:0.31-1.65,P=0.03)、每周干预大于3次(SMD=0.87,95%CI:0.30-1.44,P=0.003)和每次干预时间小于20 min(SMD=0.89,95%CI:0.61-1.66,P<0.0001)是改善慢性踝关节不稳患者功能康复效果的最佳康复方案。④Meta分析结果还显示,平衡训练可以改善星形偏移平衡测试前侧(SMD=0.56,95%CI:0.31-0.80,P<0.05)、后内侧(SMD=0.88,95%CI:0.45-1.32,P<0.05)和后外侧(SMD=0.84,95%CI:0.22-1.46,P<0.05)伸展程度。结论:当前临床证据表明,平衡训练可以改善慢性踝关节不稳患者的踝关节不稳功能症状和提高动态平衡能力,建议通过每周干预大于3次,每次干预小于20 min的干预时间以获得更好的康复效果。

The southern Jiangxi Province(SJP) and northern Jiangxi-southern Anhui provinces(NJSAP) are the two most important tungsten metallogenic districts in South China. The SJP district is a well-known tungsten producer in South China where distributes several ore concentrated areas such as the "Chongyi-Dayu-Shangyou", "Yudu" and "Longnan-Quanan-Dingnan"areas, with many large and super large tungsten deposits including the famous Xihuashan, Piaotang, Pangushan and Dajishan deposits. In recent years, major prospecting breakthrough for W-polymetallic resources has been made in the NJSAP *** large and super large W-Cu(Mo) deposits, such as the Dahutang, Zhuxi, Dongyuan and Baizhangyan deposits, are discovered. These deposits are all genetically associated with the Yanshanian(Mesozoic) granitic magmatism. In this study, a systematic comparison of the temporal and spatial distribution, petrology, geochronology, and geochemical characteristics of the tungsten-bearing granites between the SJP and NJSAP districts has been made, with an aim to improving the understanding of the petrogenesis of the granites and associated metal enrichment mechanisms in the two tungsten ore districts in South China. The following conclusions can be drawn:(1) The ages of the tungsten-bearing granites and associated mineralization are different in the two districts, in the SJP district the ages are mainly concentrated in 165–150 Ma, whereas in the NJSAP district it displays two age periods, one is 150–140 Ma(Late Jurassic-Early Cretaceous), and the other is 135–120 Ma(Early Cretaceous).(2) The tungsten-bearing granites from both the NJSAP and SJP districts are highly fractionated granitic rocks, but the SJP granites have experienced higher degree of fractional crystallization and more extensive fluid metasomatism than the NJSAP granites.(3) The petrogeneses of the tungsten-bearing granites from the two districts are different, those from the NJSAP district originated from partial melting
