浅谈胡澍手校本《素问》的文献版本价值

清末经学家和小学家胡澍把《素问》作为子书之一，博采众本，悉心校勘，以小学的方法进行专门研究，撰成《素问校义》，为研习《内经》不可不读之书。通过对天津中医药大学图书馆所藏胡澍手校本《重广补注黄帝内经素问》的考证，发现胡澍校勘所据底本一直被误作宋本，而实是明顾从德影宋刻本．校勘工作历时数年，手校本《素问》留有胡澍悉心对校后所做出的千余条校语，可惜草创未就，他便英年早逝。手校本这第一手资料，对研究胡澍的治学思想和《素问校义》的成书过程，学习和掌握知识，传承弘扬学术，都具有重女的文献参考价值。     

双能量CT头颅血管成像的影像质量、辐射剂量及初步临床应用

Objective To assess the clinical value of dual-energy intracranial CT angiography (CTA).Methods Forty-one patients suspected of intracranial vascular diseases underwent dual-energy intracranial CT angiography, and 41 patients who underwent conventional subtraction CT were enrolled as the control group.Image quality of intracranial and skull base vessels and radiation dose between dual-energy CTA and conventional subtraction CTA were compared using two independent sample nonparametrie test and independent-samples t test, respectively.Prevalence and size of lesions detected by dual-energy CTA and digital subtraction CTA were compared using paired-samples t test and Spearman correlative analysis. Results The percentage of image quality scored 5 was 70.7% (29/41) for dual-energy CTA and 75.6% (31/41) for conventional subtraction CTA.There was no significant difference between the two groups(Z= -0.455, P=0.650).Image quality of vessels at the skull base in conventional subtraction CTA was superior to that in dual-energy CTA, especially for the petrosal and syphon segment (Z=-4.087, P= 0.000).Radiation exposure of dual energy CTA and conventional CTA were (396.54±17.43) and (1090.95±114.29) mGy · cm respectively.Radiation exposure was decreased by 64% (t=-38.52, P=0.000) by dual energy CTA compared with conventional subtraction CTA.Out of the 41 patients,19 patients were diagnosed as intracranial aneurysm, 2 patients as arteriovenous malformation (AVM), 3 patients with Moya-moya's disease, and the remaining 17 patients with negative results.Nine patients with intracranial aneurysm, 2 patients with AVM, 3 patients with Moya-moya's disease, and 2 patients with negative findings underwent DSA or operation, with concordant findings from both techniques.Diameter of aneurysm neck, long axis and minor axis by dual-energy CTA was (2.90±1.61), (5.23±1.68) and (3.83±1.69) nun, respectively; Diameter of aneurysm neck, long axis and minor axis by DSA was (2.95±1.71), (5.10±1.60) ,(3.83±1.65) nan,respectively.There was no significant difference for the diameters of aneurysm between dual energy CTA and DSA ((t=-0.734,1.936,0.12.5 respectively, P=0.482,0.085,0.903 respectively), and good correlation was found between diameter measurements using the two techniques(r=0.964,0.976,0.973, respectively, all P=0.000) Conclusions Compared with conventional subtraction CTA, dual energy CTA has good image quality for intracranial vessels; however, image quality of the skull base vessels is worse, especially for the petrosal and syphon segment.Dual energy CTA has decreased radiation dose and a high diagnostic accuracy, being a practical imaging madality for diagnosis of intracranial vascular lesions.     

自动移床3D CES MRA在下肢动脉检查中的初步应用

目的：探讨自动移床3维增强减影MR血管造影(3DCES MRA)在下肢动脉疾病检查中的应用价值。方法：16例临床怀疑下肢动脉性病变者进行了自动移床3D CES MRA认检查，原始图像经减影后作最大密度投影(MIP)重建。结果：所有病例的血管均显示满意，其中11例可见不同部位和分支动脉狭窄或闭塞，阳性诊断率为68．7％。结论：初步结果表明，自动移床3D CES MRA检查技术对下肢动脉病变有重要诊断价值。     

肝动脉解剖变异影像学研究

目的用数字减影血管造影(DSA)和CT血管造影(CTA)进一步探讨肝动脉解剖变异的种类、发生率及特点。方法回顾分析1000例因肝脏疾病而行DSA检查患者的临床资料、肝动脉的DSA,以及其中的32例肝动脉解剖变异的CTA表现。观察肝动脉的起源、走行、分布情况,并分别统计其变异类型和发生率。结果1000例肝动脉造影中,正常型727例,占72.7%;肝动脉变异273例,占27.3%。273例肝动脉变异中属于Michels分型的148例,占14.8%。Michels分型未包括在内者为125例,占12.5%。其中肝总动脉分叉变异54例,占5.4%,肝动脉起源变异214例,占21.4%,肝总动脉分叉 肝动脉起源变异5例,占0.5%。以上变异合并多种变异共存21例,占2.1%。结论肝动脉解剖变异的种类具有多样性、复杂性。除DSA外,CTA亦可显示肝动脉解剖变异。肝胆外科和影像科医师了解肝动脉解剖变异对于术前制定手术方案、提高诊断准确性等有重要意义。     

长春市美的侧貌正常He儿童Tweed、Wits、Graber分析法正常值的研究

芝麻油掺入花生油、棉籽油的定性定量检测

芝麻香油因其香味醇厚，口感较好，一直是人们喜爱的调味品。由于其价格较高，因此一些不法商人利欲熏心，常常向芝麻油中掺入低价的植物油如花生油、棉籽油等，使消费者的经济利益受到损害。为了解决食用芝麻油的掺伪问题，我们利用芝麻油的物理、化学特性，进行了芝麻油的定性、定量检测，效果较好，准确度高，操作简单可靠。

圆轨道体层摄影的影象特征、晕影高度、体层厚度和核影厚度

实验证明,圆轨道体层摄影可将一个钢球照出四种不同的影象:①与球体相似的影象,②中心密度高,四周为环带状晕影之影象;③较大的圆形晕影象;④环形晕影象,可将一个铁丝棒照出双影。作者解释了这四种球体影象和双影的形成原因,提出晕影高度、体层厚度和核厚度的公式,并强调指出,在邻近直径10mm钙化点的36°圆轨道体层片上可以照出该钙化点的核影,相似稍小一点的钙化点影象,或照出假空洞影象;在邻近直径10mm空洞的36°圆轨道体层片上可以照出该空洞的核影相似稍小一点的空洞,容易误诊。值得诊断医师注意。
