目的:从免疫学角度探讨不同穴位艾灸对原发性痛经大鼠模型NK细胞活性的影响,以期为临床治疗原发性痛经筛选出更好的穴位。方法:利用苯甲酸雌二醇注射液和缩宫素制备大鼠痛经模型,选择治疗痛经的常用腧穴神阙穴和关元穴分别对痛经大鼠进行艾灸治疗,通过观察各组大鼠脾脏重量、扭体次数、脾脏NK细胞活性含量及光镜下脾脏病理切片的变化,比较灸神阙与灸关元治疗原发性痛经的疗效,并从免疫学角度探讨艾灸治疗原发性痛经的机制。结果:(1)与空白组比较,模型组大鼠脾脏重量明显减轻(P<0.01);与模型组比较,各治疗组大鼠脾脏重量均显著增加(P<0.01)。(2)与空白组比较,模型组大鼠扭体次数明显增加(P<0.01);经治疗后,灸神阙组、灸关元组及西药组大鼠扭体次数均明显减少,与模型组比较,差异均有显著统计学意义(P<0.01)。(3)与空白组比较,模型组大鼠脾脏NK细胞活性明显降低(P<0.01);与模型组大鼠脾脏NK细胞活性比较,西药组有统计学意义(P<0.05),灸神阙组与灸关元组均有显著统计学意义(P<0.01)。镜下观察到各治疗组大鼠的脾脏结构均存在,与模型组比较,西药组大鼠脾脏淋巴小结数目及面积稍增多增大,而灸神阙组与灸关元组大鼠脾脏淋巴小结数目及面积均明显增多增大,且灸关元组大鼠脾脏淋巴小结数目稍多于灸神阙组。结论:灸关元穴与灸神阙穴均可通过升高原发性痛经大鼠脾脏NK细胞活性而发挥镇痛作用,但灸关元穴比灸神阙穴对原发性痛经大鼠的免疫影响更明显。

The pre-earthquake ionospheric anomalies in Wenchuan,China(21°-41°N,93°-113°E)are studied and analyzed using the summer nighttime data from 2005 to 2008 measured by DEMETER(Detection of Electro-Magnetic Emission Transmitted from Earthquake Regions)satellite detectors ICE(Internet Communications Engine),IAP(In Application Programming),and ISL(Interior Switching Link).In this paper,we take the 12 May 2008 Wenchuan earthquake as an example,use the spatial gridding method to construct the background field over the epicenter,analyze the background characteristics of very low frequency(VLF)electric field components,low-energy particle parameters,and plasma parameters,and define the perturbation intensity index of each parameter before the earthquake to extract each parameter anomaly in both space and time *** results show that the background values of some ionospheric parameters in the Wenchuan area are related to spatial ***,anomalous enhancement of low-frequency electric field power spectral density,H+concentration,He+concentration and ion concentration with different intensities and anomalous weakening of ion temperature were extracted in the fifteen days before the Wenchuan *** filtering the data to exclude external interference,such as solar activity,this paper concludes that there is some connection between these anomalies and the Wenchuan earthquake.

为提高速冻库沙棘枝条果速冻效率,本文在速冻库中设计导流板解决速冻库顶部形成漩涡区的问题,通过计算流体域的方法,应用SIMPLE算法求解微分方程,对速冻库加导流板前后冷库模型中速度场和温度场变化进行数值模拟,研究表明在未加导流板时沙棘速冻库内部存储物料区回流较少,不利于沙棘枝条果速冻,加入导流板后有利于改变速冻库内部气流,加速气流通过存料区,该研究结果为速冻库的设计和优化提供参考。

为解决鱼麟册失修与灾害带来的田赋混乱问题,晚清山西各地相继开展土地清丈与鱼鳞册攒造活动,尤以解州等地成效显著,成为晚清土地清丈的典范。这次清丈重建鱼鳞册制度,形成地方政府直接掌握的土地登记与钱粮征收册籍体系,里甲体系也得到重塑。从各地清丈章程与现存鱼鳞册实物看,清丈系履亩实丈,鱼鳞册登记的土地数字具有实际意义。同时,山西各地的清丈关联密切,其开展离不开以阎敬铭与张之洞为中心形成的土地清丈官员网络圈。随着官员调任升迁,山西清丈经验得到重视,影响有一定扩大。
