| 1 | Texture analysis on parametric maps derived from dynamic contrast-enhanced magnetic resonance imaging in head and neck cancer显示文摘AIM: To investigate the merits of texture analysis on parametric maps derived from pharmacokinetic modeling with dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI) as imaging biomarkers for the prediction of treatment response in patients with head and neck squamous cell carcinoma(HNSCC). METHODS: In this retrospective study,19 HNSCC patients underwent pre- and intra-treatment DCEMRI scans at a 1.5T MRI scanner. All patients had chemo-radiation treatment. Pharmacokinetic modeling was performed on the acquired DCE-MRI images,generating maps of volume transfer rate(Ktrans) and volume fraction of the extravascular extracellular space(ve). Image texture analysis was then employed on maps of Ktrans and ve,generating two texture measures: Energy(E) and homogeneity.RESULTS: No significant changes were found for the mean and standard deviation for Ktrans and ve between pre- and intra-treatment(P > 0.09). Texture analysis revealed that the imaging biomarker E of ve was significantly higher in intra-treatment scans,relative to pretreatment scans(P < 0.04). CONCLUSION: Chemo-radiation treatment in HNSCC significantly reduces the heterogeneity of tumors. | Jacobus FA Jansen Yonggang Lu Gaorav Gupta Nancy Y Lee Hilda E Stambuk Yousef Mazaheri Joseph O Deasy Amita Shukla-Dave | 2016 | World Journal of Radiology2016，8，1： | 5 |

| 3 | 非高密度脂蛋白胆固醇、载脂蛋白A-I及B100、标准脂质测量、脂质比值以及CRP作为女性心血管病危险因素的临床用途显示文摘背景:关于不同脂质测定、非高密度脂蛋白胆固醇(non-HDL-C)、脂质比值、载脂蛋白和C-反应蛋白(CRP)的临床应用,现行心血管危险检测指南仍有争议。
目的:直接比较总胆固醇(totalcholesterol,TC)、低密度脂蛋白胆固醇(LDL-C)、HDL-C、non-HDL-C、载脂蛋白A-I(apoA-I)及B100(apoB100)、高敏C-反应蛋白(高敏CRP)以及TC与HDL-C、LDL-C与HDL-C、apoB100与apoA-I、apoB100与HDL-C比值,在妇女作为将来心血管事件预测指标的临床用途。
设计、地点及参试者:于15 632例起始健康美国妇女进行的前瞻性队列研究。1992年11月至1995年7月人组时年龄≥45岁(4分位范围48~59岁)。所有参试者均经10年随访,观察将来心血管事件的发生情况。
主要观测指标:按照各项生化指标不同基线值而确定的首次主要心血管事件(n=4 764)的风险比(hazard ratios,HRs)及95%可信区间(confidence intervals,CIs)。
结果:在校正年龄、吸烟状况、血压、糖尿病及体重指数后,测量结果在最高5分位者将来发生心血管事件的风险比LDL-C为1.62(95%CI,1.17~2.25),apoA-I为1.75(95%CI,1.30~2.38),TC为2.08(95%CI,1.45~2.97),HDL-C为2.32(95%CI,1.64~3.33),apoB100为2.50(95%CI,1.68~3.72),non-HDL-C为2.51(95%CI,1.69~3.72),高敏CRP为2.98(95%CI,1.90~4.67)(P<0.001,趋势贯穿所有5分位)。脂质比值风险比,apoBl00与apoA-I为3.01(95%CI,2.01~4.50),LDL-C与HDL-C为3.18(95%CI,2.12~4.75),apoB100与HDL-C为3.56(95%CI,2.31~5.47),TC与HDL-C为3.81(95%CI,2.47~5.86)(P<0.001,趋势贯穿所有5分位)。高敏CRP与脂质参数的相关系数范围为-0.33到0.15,以CRP<1、1~3和>3 ms/L为临床分割点,可对每项脂质测量及脂质比值水平增加提供预后危险信息。
结论:non-HDL-C以及TC与HDL-C比值对将来心血管事件的预测效果与载脂蛋白相同或者更好。校正年龄、血压、吸烟、糖尿病和肥胖后,高敏CRP提供的预后信息超越各项脂质测量。 | Paul M Ridker Nader Rifai Nancy R.Cook Gary Bradwin Julie E Buring 徐成斌(译) | 2006 | 美国医学会杂志(中文版)2006，25，3： | 3 |

| 6 | Changes in efficiency and resource utilization after increasing experience with double balloon enteroscopy显示文摘AIM:To investigate changes in efficiency and resource utilization as a single endoscopist's experience increased with each subsequent 100 double balloon enteroscopy(DBE) procedures.METHODS:We reviewed consecutive DBE procedures performed by a single endoscopist at our center over 4 years.DBE was employed when the clinician deemed the procedure was needed for disease management.The approach(oral,anal or both) was chosen based on suspected location of the target lesion.All DBE was performed in a standard endoscopy room with a portable fluoroscopy unit.Fluoroscopy was used to aid in shortening the small intestine and reducing bowel loops.For oral DBE,measurements were taken from the incisors.For anal DBE,measurements were taken from the anal verge.Enteroscopy continued until the target lesion was reached,until the entire small intestine was examined,or until no further progress was deemed possible.The length of small intestine examined(cm),procedure duration(min),and fluoroscopy time(s) were analyzed for sequential groups of 100 DBE.Sub-groups of diagnostic and therapeutic procedures were analyzed using multivariable linear regression.RESULTS:802 consecutive DBE procedures were analyzed.For oral DBE,median [interquartile range(IQR)] length of small bowel examined was 230.8 cm(range:210-248 cm) and for anal DBE was 143.5 cm(range:100-180 cm).No significant increase in length examined was noted for either the oral or anal approach with advancing position in series.In terms of duration of procedure,the median(IQR) for oral DBE was 86 min(range:71-105 min) and for anal DBE was 81.3 min(range:67-105 min).When comparing by the position in series,there was a significant(P value < 0.001) decrease in procedure duration for both upper and lower procedures with increasing experience.Median(IQR) time of exposure to fluoroscopy for oral DBE was 190 s(114-275) compared to anal DBE which was 196.4 s(312-128).This represented a significant(P value < 0.001) decrease in the amount of fluoroscopy used with increasing position in series.For both oral and anal DBE,fluoroscopy time was reduced by greater than 50% over the course of 802 total procedures performed.Sub-group analysis was conducted on therapeutic and diagnostic groups.Out of 802 procedures,a total of 434 were considered therapeutic.Argon plasma coagulation was by far the most common therapeutic intervention performed.There was no evidence of a difference in length examined or fluoroscopy exposure among oral DBE for diagnostic and therapeutic procedures,P = 0.91 and P = 0.32 respectively.The median(IQR) for length was 235 cm(range:178-280 cm) for diagnostic vs 230 cm(range:180-275 cm) for therapeutic procedures;additionally,fluoroscopy time median(IQR) was 180 s(range:110-295 s) and 162 s(range:102-263 s) for no intervention and intervention.However,there was a significant difference in procedure duration among oral DBE(P < 0.001).The median(IQR) was 80 min(range:60-97 min) and 94 min(range:77-110 min) for diagnostic and therapeutic interventions respectively.CONCLUSION:For a single endoscopist,increased DBE experience with number of performed procedures is associated with increased efficiency and decreased resource utilization. | Neal C Patel William C Palmer Kanwar R Gill David Cangemi Nancy Diehl Mark E Stark | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，3： | 2 |
