PDR diagnostics study with CLOUDY

A series of plane-parallel photodissociation region (PDR) models are calculated using the spectral synthesis code CLOUDY. These models span a wide range of physical conditions, with gas densities of n = 102 - 106 cm-3 and incident far-ultraviolet (FUV) fields of G0 = 100 - 106 (where Go is the FUV flux in units of the local interstellar value), which are comparable with various astrophysical environments from interstellar diffuse clouds to the dense neutral gas around galactic compact HII regions. Based on the calculated results, we study the thermal balance of PDR gas and the emissions of [ CII ], [ CI ] and [ OI ] fine-structure lines under different physical conditions. The intensities and strength ratios of the studied lines, which are frequently used as PDR diagnostics, are presented using contour diagrams as functions of n and Go. We compare the calculated PDR surface gas temperatures T8 with those from Kaufman et al. and find that Ts from our models are systematically higher over most of the adopted n-G0 parameter space. The predicated line intensities and ratios from our work and those from Kaufman et al. can be different by a factor greater than 10, and such large differences usually occur near the border of our parameter space. The different methods of treating the dust grain physics, the change of H2 formation and dissociation rates, and the improvement in the radiation transfer of line emissions in our CLOUDY models are likely to be the major reasons for the divergences. Our models represent an up-to-date treatment of PDR diagnostic calcula- tions and can be used to interpret observational data. Meanwhile, the uncertainties in the treatment of microphysics and chemical processes in PDR models have significant effects on PDR diagnostics.     

减影CTA在颅内静脉窦病变的诊断价值

目的:探讨减影CTA在颅内静脉窦病变的影像特点及诊断价值。方法:收集28例颅内静脉窦病变患者,其中动静脉畸形9例,静脉畸形3例,颅内静脉窦血栓4例,颈内动脉海绵窦瘘2例,肿瘤累及静脉窦10例;行CT平扫,增强及减影CTA,研究病变显示情况及诊断价值。结果:28例患者CTA静脉影像显示成功率为100%,可清楚显示病变位置,大小,形态以及与周围血管的关系。结论:减影CTA对颅内静脉窦病变具有无创,安全,快捷,准确性高等特点,可作为颅内静脉窦病变有效的检查方法。     

针灸治疗糖尿病周围神经病变的取穴规律探究

目的：探究针灸治疗糖尿病周围神经病变的取穴规律,以期为针灸治疗糖尿病周围神经病变的临床取穴提供指导。方法：以“糖尿病周围神经病变”和“针灸”为检索词,查阅中国知网（CNKI）近10年来的相关文献,对其中所选用的腧穴进行整理、归纳,分析腧穴的种类、归经、所属部位及使用频次。结果：纳入文献共34篇中,用穴共72个,其中十四经穴66个,经外奇穴6个,腧穴总使用频次为461次（其中主穴117次,配穴344次）;最常用的主穴有足三里、胃脘下俞、肾俞、脾俞、三阴交、合谷、关元、肝俞、曲池、太溪;归经以足太阳膀胱经、足阳明胃经、足太阴脾经、手阳明大肠经为主;特定穴中以背俞穴、合穴及经外奇穴为主;配穴主要以病变四肢取穴为主。结论：针灸治疗糖尿病周围神经病变多以背俞穴结合病变四肢取穴为主,主穴与配穴相结合。     

卜献春治疗糖尿病心脏自主神经病变经验

总结卜献春教授治疗糖尿病心脏自主神经病变的经验。卜教授认为本病病位在“心”“络脉”,累及脾肾,其发病与“虚”和 “瘀”密切相关,“虚”为脾气亏虚、肾阴亏虚、心气亏虚、心阴亏虚、心阳虚衰;“瘀”为心脉瘀阻、痰瘀互结。临床选用益气养阴、活血通络之滋膵通脉饮为主方,结合心脾两虚、心肾阴虚、心阳不振、心脉瘀阻等证,合方加减,辨证施治,临床疗效显著。附验案1则,以资佐证。     

基于中医传承辅助系统的糖尿病周围神经病变用药规律分析

目的：基于中医传承辅助系统软件（V2.5）,分析中药治疗糖尿病周围神经病变的用药规律,以期更好地指导临床治疗。方法：收集CNKI中采用中药治疗糖尿病周围神经病变的验案,筛选出方剂组成、剂量完整者,录入系统软件,分析其中的用药规律。结果：选取验案102篇,筛选出方剂47首,涉及中药145味。方中黄芪出现的频次最多,其中出现频次14以上的药物中活血化瘀药物占50%;出现频率最高的药对为黄芪+鸡血藤。演化得到核心组合6个,新处方3首;置信度>0.9的关联规则包括红花→黄芪,桃仁→当归,葛根、黄芪→鸡血藤等。结论：通过中医传承辅助系统对CNKI数据库筛选出的治疗糖尿病周围神经病变的方剂进行分析,得出组方用药以活血化瘀通络、补中益气为主;基于熵层次聚类算法的新方以补气活血、化瘀通痹为主,进而揭示组方规律,为临床治疗提供参考。
