| 1 | Passive expansion of sub-maximally dilated transjugular intrahepatic portosystemic shunts and assessment of clinical outcomes显示文摘AIM To assess for passive expansion of sub-maximally dilated transjugular intrahepatic portosystemic shunts(TIPS) and compare outcomes with maximally dilated TIPS.METHODS Polytetrafluoroethylene covered TIPS(Viatorr) from July 2002 to December 2013 were retrospectively reviewed at two hospitals in a single institution. Two hundred and thirty patients had TIPS maximally dilated to 10 mm(m TIPS), while 43 patients who were at increased risk for hepatic encephalopathy(HE), based on clinical evaluation or low pre-TIPS portosystemic gradient(PSG), had 10 mm TIPS sub-maximally dilated to 8 mm(sm TIPS). Group characteristics(age, gender, Model for End-Stage Liver Disease score, post-TIPS PSG and clinical outcomes were compared between groups, including clinical success(ascites or varices), primary patency,primary assisted patency, and severe post-TIPS HE. A subset of fourteen patients with sm TIPS underwent follow-up computed tomography imaging after TIPS creation, and were grouped based on time of imaging(< 6 mo and > 6 mo). Change in diameter and crosssectional area were measured with 3D imaging software to evaluate for passive expansion.RESULTS Patient characteristics were similar between the sm TIPS and m TIPS groups, except for pre-TIPS portosystemic gradient, which was lower in the sm TIPS group(19.4 mm Hg ± 6.8 vs 22.4 mm Hg ± 7.1, P = 0.01). Primary patency and primary assisted patency between sm TIPS and m TIPS was not significantly different(P = 0.64 and 0.55, respectively). Four of the 55 patients(7%) with sm TIPS required TIPS reduction for severe refractory HE, while this occurred in 6 of the 218 patients(3%) with m TIPS(P = 0.12). For the 14 patients with follow-up computed tomography(CT) imaging, the median imaging follow-up was 373 d. There was an increase in median TIPS diameter, median percent diameter change, median area, and median percent area change in patients with CT follow-up greater than 6 mo after TIPS placement compared to follow-up within 6 mo(8.45 mm, 5.58%, 56.04 mm^2, and 11.48%, respectively, P = 0.01).CONCLUSION Passive expansion of sm TIPS does occur but clinical outcomes of sm TIPS and m TIPS were similar. Sub-maximal dilation can prevent complications related to overshunting in select patients. | Michael C Hsu Charles N Weber S William Stavropoulos Timothy W Clark Scott O Trerotola Richard D Shlansky Goldberg Michael C Soulen Gregory J Nadolski | 2017 | World Journal of Hepatology2017，9，12： | 11 |
| 2 | Determinants of the impact of blood pressure variability on neurological outcome after acute ischaemic stroke显示文摘Introduction: Increased blood pressure variability (BPV) is detrimental after acute ischaemic stroke, but the interaction between BPV and neuroimaging factors that directly influence stroke outcome has not been explored. Methods: We retrospectively reviewed inpatients from 2007 to 2014 with acute anterior circulation ischaemic stroke, CT perfusion and angiography at hospital admission, and a modified Rankin Scale (MRS) 30- 365 days after stroke onset. BPV indices included SD, coefficient of variation and successive variation of the systolic blood pressure between 0 and 120 hours after admission. Ordinal logistic regression models were fitted to MRS with predictor variables of BPV indices. Models were further stratified by CT perfusion volumetric measurements, proximal vessel occlusion and collateral score. Results: 110 patients met the inclusion criteria. The likelihood of a 1-point rise in the MRS increased with every 10 mm Hg increase in BPV (OR for the 3 BPV indices ranged from 2.27 to 5.54), which was more pronounced in patients with larger ischaemic core volumes (OR 8.37 to 18.0) and larger hypoperfused volumes (OR 6.02 to 15.4). This association also held true for patients with larger mismatch volume, proximal vessel occlusion and good collateral vessels. Conclusions: These results indicate that increased BPV is associated with worse neurological outcome after stroke, particularly in patients with a large lesion core volume, concurrent viable ischaemic penumbra, proximal vessel occlusion and good collaterals. This subset of patients, who are often not candidates for or fail acute stroke therapies such as intravenous tissue plasminogen activator or endovascular thrombectomy, may benefit from interventions aimed at reducing BPV. | Adam de Havenon Alicia Bennett Gregory J Stoddard Gordon Smith Lee Chung Steve O’Donnell J Scott McNally David Tirschwell Jennifer J Majersik | 2017 | Stroke & Vascular Neurology2017，2，1： | 6 |
| 3 | 4号染色体短臂微卫星多态性与鼻咽癌相关性的研究显示文摘鼻咽癌(NPC)是一种多因素复杂疾病。其发病过程涉及EB病毒慢性感染、环境致癌因素及宿主基因之间的相互作用。在这一过程中,那些宿主基因在EB病毒感染及鼻咽癌的发生发展中起了关键作用仍不清楚。本研究的目的是发现与鼻咽癌发生发展中两个关键步骤相关的遗传变异,即EB病毒持续性感染鼻咽部上皮细胞和鼻咽癌的形成。我们在广西梧州市及苍梧县鼻咽癌高发区收集汉族鼻咽癌患者350例、EB病毒壳抗原IgA抗体阳性者(IgA/VCA+)288例和EB病毒壳抗原IgA抗体阴性者(IgA/VCA—)346例。对先前鼻咽癌家系研究显示的鼻咽癌易感区4号染色体短臂(4p15.1~q12)进行了微卫星精细扫描,在18Mb的范围内选择34个微卫星标记,包括319个等位基因,对其进行基因分型。比较分析NPC组和IgA/VCA+组等位基因频率结果显示,9个等位基因与鼻咽癌呈相关,其中5个为易感等位基因(OR=1.51~5.36,P=0.01~0.03),4个为限制性等位基因(OR值为0.3~0.71,P值为0.02~0.045)。比较分析IgA/VCA+组和IgA/VCA-组及比较所有IgA/VCA+者(包括NPC患者)和IgA/VCA-者等位基因频率的结果显示,12个等位基因与EB病毒壳抗原IgA抗体持续存在相关,其中3个在两组比较中均呈显著相关。等位基因D4S3241~136(P=0.004,OR=1.9,95%CI=1.2~3.0)和D4S3347-213(P=0.001,OR=1.6,95%CI=1.2~2.1)可增加EB病毒IgA/VCA抗体形成的危险,为易感基因;而等位基因D4S174.202(P=0.001,OR=0.5,95%CI=0.3~0.7)可限制IgA/VCA抗体的形成。但上述结果经多因素比较校正后,均失去相关性。结果不能确定该区域与非家族性鼻咽癌的形成相关,但本研究却提供了进一步发现鼻咽癌相关基因的研究模式。有关4号染色体短臂与EB病毒慢性持续感染及鼻咽癌的形成仍值得进一步深入研究。 | 郭秀婵 O’BRIEN Stephen J WINKLER Cheryl SCOTT Kevin HUTCHESON Holli DAVID Victor KESSING Bailey 郑裕明 廖建 刘彦 GUY de The 曾毅 | 2006 | 遗传2006，28，7： | 2 |
