足头向穿刺路径在膈肌下方肝肿瘤消融治疗中的CT模拟测量研究

【摘要】 目的 对足头向穿刺路径进行模拟测量并评价在膈肌下方肝肿瘤热消融治疗中的临床应用价值。方法 重建患者上腹部CT图像，选取有代表性的3个矢状面和1个冠状面作为标准层面，在各层面建立膈下标准病灶模型，并采用足头向穿刺路径进行模拟穿刺。测量各平面上膈肌高度、穿刺路径长度及间距。采用可到达性评价模拟穿刺时穿刺针分布于标准病灶中的最理想的位置情况。结果 纳入86例患者行测量研究，多数患者矢状2、3面的膈肌高度低于2cm，仅分别对平面内1511%的病灶e和813%的病灶f进行了测量。标准病灶a、b、c、d、b’的完全到达比例分别为5243%、6097%、3837%、5294%、6353%，中位路径长度分别为1039cm、1337cm（背侧，腹侧1266cm）、1315cm、888cm、1126cm，中位穿刺路径间距分别为21cm、209cm（背侧，214cm腹侧）、206cm、211cm、2145cm。结论 采用足头向穿刺路径进行穿刺，标准病灶a、b、d、b’有较高的完全到达比例，穿刺宽容度较高，有进一步在临床中应用的价值。标准病灶c的完全到达率不高。标准病灶e、f需要采用该路径穿刺的比例不高。

浅谈“从温治咳”

咳嗽病因病机复杂多变,宣降失司、肺气上逆是发病的关键。外感咳嗽,辛温与宣降并用,驱邪理肺,宣畅气机,则咳止;内伤致咳,温补肺脾肾三脏,通调水道,排除多余水液,使痰无由生,又可调畅气机,从而减少咳嗽;感染后咳嗽为本虚标实,宜重温阳润肺,则余邪自散,咳嗽得止;素体阳虚者,当温补脾肾,使邪气无由生,咳嗽无由发。因此,对于临床常见症状咳嗽的治疗,应重视温法的应用,然切记以正确辨证为前提,不可一味温补。     

“治未病”思想在老年高血压病防治中的应用探讨

老年高血压病以肾气亏虚为主要病机,具有特殊的发病基础、临床症状、传变规律和预后。以"治未病"思想为指导,在老年高血压病发生、发展、预后的各个阶段进行提前干预,有利于扶助正气,增强抗病能力,延缓病情进展。具体而言,未病之时,应通过调整生活方式、服用中药保养和培补肾气,做到未病先防。已病之时,既病防变,阴阳俱虚者,治以补益肾气,方选肾气丸加减;肾阴虚者,治以滋阴补肾,方选左归丸合天麻钩藤饮加减;肾阳虚者,治以温补肾阳,方选右归丸加减。疾病初愈之时,继续以中药补肾虚、调气血,同时避免六淫邪气与情志内伤对机体的损害,以防疾病复发。

Analysis of the uninjured tibiofibular syndesmosis using conventional CT-imaging and axial force in different foot positions

BackgroundSyndesmosis measurments and indices have been controversial and showed interindividual variability. The purpose of this study was to analyze, by conventional axial computed tomography images and a simulated load device, the uninjured tibiofibular syndesmosis under axial force and forced foot positions.MethodsA total of 15 healthy patients (30 ankles) were studied using adjustable simulated load device (ASLD). This device allowed to perform bilateral ankle CT scans in two forced foot and ankle positions (30° of plantar flexion, 15° of inversion, 20° of internal rotation and 15° of dorsal flexion, 15° of eversion, 30° of external rotation). Axial load was applied simultaneously in a controlled manner (70% body weight). Measurements on the axial image of computed tomography were: syndesmotic area (SA), fibular rotation (FR), position of the fibula in the sagittal plane (FPS), depth of the incisura (ID) and direct anterior difference (ADD), direct middle difference (MDD) and direct posterior difference (PDD).ResultsIn patients without injury to the tibiofibular syndesmosis, the application of axial load and forced foot and ankle positions showed statistically significant differences on the distal tibiofibular measurements between the stressed and the relaxed position, it also showed interindividual variability : SA (median = 4.12 [IQR = 2.42, 6.63]) (p < 0.001), ADD (0.67 [0.14, 0.67]) (p < 0.001), MDD(0.45, [0.05, 0.9]) (p < 0.001), PDD (0.73 [?0.05, 0.73]) (p < 0.002). However, it did not detect statistically significant differences when the tibiofibular differences between the stressed and the relaxed position in one ankle were compared with the contralateral side: SA (?0.14, SD = 4.33 [95% CI = ?2.53, 2.26]), ADD (?0.42, 1.08 [?1.02, 0.18]), MDD (0.29, 0.54 [?0.01, 0.59]), PDD (?0.1, 1.42 [?0.89, 0.68]). Interobserver reliability showed an Intraclass correlation coefficient of 0.990 [95% CI = 0.972, 0.997].ConclusionsWide interindividual variability was observed in all syndesmotic measurements, but no statistically significant differences were found when comparing one ankle to the contralateral side. Measuring syndesmosis alignment parameters, may only be of value, if those are compared to the contralateral ankle.     

Clinical equivalence assessment of T2 synthesized pediatric brain magnetic resonance imaging

Background and purposeAutomated synthetic magnetic resonance imaging (MRI) provides qualitative, weighted image contrasts as well as quantitative information from one scan and is well-suited for various applications such as analysis of white matter disorders. However, the synthesized contrasts have been poorly evaluated in pediatric applications. The purpose of this study was to compare the image quality of synthetic T2 to conventional turbo spin-echo (TSE) T2 in pediatric brain MRI.Materials and methodsThis was a mono-center prospective study. Synthetic and conventional MRI acquisitions at 1.5 Tesla were performed for each patient during the same session using a prototype accelerated T2 mapping sequence package (TA_synthetic = 3:07 min, TA_conventional = 2:33 min). Image sets were blindly and randomly analyzed by pediatric neuroradiologists. Global image quality, morphologic legibility of standard structures and artifacts were assessed using a 4-point Likert scale. Inter-observer kappa agreements were calculated. The capability of the synthesized contrasts and conventional TSE T2 to discern normal and pathologic cases was evaluated.ResultsSixty patients were included. The overall diagnostic quality of the synthesized contrasts was non-inferior to conventional imaging scale (P = 0.06). There was no significant difference in the legibility of normal and pathological anatomic structures of synthetized and conventional TSE T2 (all P > 0.05) as well as for artifacts except for phase encoding (P = 0.008). Inter-observer agreement was good to almost perfect (kappa between 0.66 and 1).ConclusionsT2 synthesized contrasts, which also provides quantitative T2 information that could be useful, could be suggested as an equivalent technique in pediatric neuro-imaging, compared to conventional TSE T2.
