BACKGROUND： Studies have shown that sensory transduction is a way to introduce needle sensation. OBJECTIVE： To observe the influence of electro-acupuncture at the ＂Zusanll＂（ST 36） point on lower extremity motor function in various sensory disturbance patients with cerebral stroke. DESIGN, TIME AND SETTING： A randomized, controlled, clinical study was performed at the Department of Neurological Rehabilitation, China Rehabilitation Research Centre from September 2006 to June 2008. PARTICIPANTS： Patients with first-time cerebral infarction or hemorrhage, or with a stroke history, but no neurodysfunction （single damage）, were selected for this study. The subjects were right-handed and disease state was stable. A total of 240 inpatients were randomly assigned to the following groups： electro-acupuncture （n = 124） and control （n = 116）. The two groups were further assigned into sub-groups： no sensory disturbance, superficial sensory disturbance, deep sensory disturbance, and deep and superficial sensory disturbance. METHODS： On the basis of routine limb function training, the acupoint Zusanliwas utilized in all patients from the electro-acupuncture group. Perpendicular acupuncture was 3.0-4.0 cm deep. An electric acupuncture instrument was connected when patients developed the needle sensation, deqi. A stimulation pattern consisting of distant and dense waves of 50 Hz was used to elicit slight dorsal foot extension. Acupuncture was administered 5 times per week, 30 minutes per session, for 6 weeks in total. MAIN OUTCOME MEASURES： FugI-Meyer assessment （FMA） was used to evaluate lower extremity motor function; Ver.1.0 gait analysis to estimate gait （step frequency, step speed, and step scope）; lower extremity Composite Spasticity Scale （CSS） to estimate muscle spastic degree. RESULTS： Following treatment, motor function improved in both groups. Compared with the control group, FMA score, step speed, step frequency, and step scope were increased in the electro-acupuncture

Conservation laws of the complex short pulse equation and coupled complex short pulse equations

Communications in Theoretical Physics 2022年第7期74卷 49-56页

作者： lihua zhang Bo Shen Shuxin Han Gangwei Wang Lingshu Wang School of Mathematics and Statistics Hebei University of Economics and BusinessShijiazhuang 050061China

In this paper, the complex short pulse equation and the coupled complex short pulse equations that can describe the ultra-short pulse propagation in optical fibers are investigated. The two complex nonlinear models are turned into multi-component real models by proper transformations. Lie symmetries are obtained via the classical Lie group method, and the results for the coupled complex short pulse equations contain the existing results as particular *** on the linearizing operator and adjoint linearizing operator for the two real systems,adjoint symmetries can be obtained. Explicit conservation laws are constructed using the symmetry/adjoint symmetry pair(SA) method. Relationships between the nonlinear selfadjointness method and the SA method are investigated.

目的:在RayStation质子治疗计划系统(TPS)中为三台CT设备进行建模,验证并校准CT建模曲线。方法:使用CT设备扫描模体得到不同组织替代材料的CT值,建立CT值与质量密度(CT-MD)曲线。同时,根据各种人体组织的化学成分,计算得到CT值与阻止本领(CT-SP)曲线。在TPS中使用不同CT建模曲线计算组织替代模块的等效水厚度;利用布拉格峰测量设备测得各模块实际等效水厚度,与TPS计算值进行比较,验证不同CT建模的精度。结果:不同管电压扫描条件下,CT建模曲线差异有统计学意义。基于化学成分校准的CT-SP曲线与CT-MD曲线比较更适合质子剂量计算,但对高CT值对应的阻止本领值仍需进行修正,校准后的计算误差在3%以内。结论:本文阐述的在质子TPS中验证并校准CT值曲线的方法,证明了化学成分计量校准后的CT-SP曲线更适用于质子剂量计算。

法师系多肉植物隶属于景天科莲花掌属(Aeonium),具有多个彩叶品种,观赏价值较高。然而,国内外还鲜有此类植物分子生物学方面的研究。为筛选出在不同法师系品种间稳定表达的内参基因,本研究以5个法师系品种叶片为材料,以法师系品种‘墨法师’和‘绿羊绒’转录组库为依据,筛选出了8个候选的qRT-PCR (quantitative RT-PCR)内参基因,并通过qRT-PCR分析了这些内参在不同品种间的表达丰度,经Genorm、normFinder、BestKeeper分析和综合分析,最终筛选出了法师系不同品种间的最适内参基因GAPDH。以该基因为内参基因,对‘墨法师’和‘绿羊绒’转录组数据库中差异表达的花青素合成酶相关基因进行表达水平验证,结果显示,除了AaCHS外,其他6个基因在上述2个品种中确实存在差异表达,进一步表明GAPDH适合作为法师系不同品种间基因表达分析的内参。本研究可为在法师系不同品种间进行基因表达分析奠定坚实的基础。

目的探讨免疫球蛋白G4相关性自身免疫性胰腺炎(IgG4-AIP)超声造影特征及超声引导下组织学活检在该病诊断中的价值。方法回顾性收集12例经超声引导下胰腺穿刺病理证实的IgG4-AIP患者的临床资料，分析其常规超声、超声造影及穿刺结果。结果 12例IgG4-AIP患者中，常规超声分为3型：局灶型8例，多灶型2例，弥漫型2例。6例患者接受超声造影，2例呈高增强，3例呈等增强，1例呈低增强。12例患者均接受超声引导下胰腺穿刺活检，术中及术后均未出现出血、感染及导管损伤等并发症。结论常规超声对IgG4-AIP尤其是类肿瘤样IgG4-AIP的诊断及鉴别诊断存在困难，超声造影有助于该病的诊断，且超声引导下胰腺穿刺活检安全、可靠。
