Patient preferences and predicted relative uptake for targeted therapies in metastatic colorectal cancer: a discrete choice experiment

Abstract

Objective

Ras wild-type metastatic colorectal cancers (mCRC) may be treated with anti-vascular endothelial growth factor (VEGF) or anti-epidermal growth factor receptor (EGFR) agents. We aim to estimate patients’ preferences for mCRC treatment and relative importance of cost, efficacy improvement, avoidance of side effects and therapy convenience, and relative uptake between profiles that resemble Bevacizumab (anti-VEGF) and Cetuximab (anti-EGFR), two commonly prescribed mCRC targeted therapies.     

Quality of oral anticoagulation control in Chinese patients with non-valvular atrial fibrillation: a prospective controlled study

Abstract

Objective

The sex, age, medical history, treatment, tobacco use, race risk (SAMe-TT₂R₂) Score; the sex, age, medical history, treatment, tobacco use, genotype combination (SAMe-TT₂G₂) Score; and the so-called modified SAMe-TT₂R₂ scores have been proposed to predict the anticoagulation quality for patients with non-valvular atrial fibrillation (NVAF). The data from a prospective controlled study is used to validate the SAMe-TT₂R₂ and SAMe-TT₂G₂ scores in Chinese NVAF patients treated with warfarin and to evaluate the association of factors with time in therapeutic range (TTR) to predict the quality of oral anticoagulation control.     

沙鼠肝泡球蚴组织中微血管密度、血管内皮生长因子的表达及意义

目的研究沙鼠肝泡球蚴组织中微血管密度(MVD)-CD34及血管内皮生长因子(VEGF)的表达及意义。方法将60只健康的长爪沙鼠随机平均分为2组,即实验组和对照组。实验组沙鼠采用开腹肝穿刺法,每只鼠接种原头节悬混液0.1 m L,对照组以相同的方法接种等量的PBS。分别于接种后第20、40、60、80、100 d时每组各处死6只沙鼠,实验组分别取泡球蚴组织和泡球蚴周围肝组织,对照组取正常肝组织。免疫组织化学法观察各时间点沙鼠肝泡球蚴组织中MVD-CD34及VEGF的表达情况。结果感染泡球蚴沙鼠肝脏中均见大小不等的团块状囊泡组织,部分播散至腹腔。在感染的各时间点,泡球蚴组织中均可见到MVD-CD34和VEGF的表达,定位于肝泡球蚴组织"外囊"囊壁内皮细胞的细胞浆。在感染后第20 d、40 d、60 d、80 d和100 d时,泡球蚴组织中MVD分别为(9.83±3.87)/HP、(25.33±6.71)/HP、(34.50±5.50)/HP、(37.67±5.71)/HP和(44.67±4.93)/HP,与泡球蚴周围肝组织〔0/HP、(1.17±0.98)/HP、(3.50±1.38)/HP、(5.83±2.71)/HP、(8.83±2.48)/HP〕和正常肝组织(均为0)相比,差异均有统计学意义(P0.05)。各时间点泡球蚴组织中VEGF免疫组织化学评分分别为(2.95±0.46)分、(3.90±0.68)分、(4.27±1.05)分、(5.33±0.95)分和(4.50±0.81)分,与泡球蚴周围肝组织〔(1.07±0.63)分、(1.38±0.75)分、(1.55±0.83)分、(1.67±0.47)分、(2.10±0.55)分〕和正常肝组织〔(1.02±0.83)分、(1.12±0.63)分、(1.26±0.26)分、(1.20±0.74)分、(1.21±0.28)分〕相比,差异均有统计学意义(P0.05)。结论血管生成可能是泡球蚴浸润性生长的机制之一,VEGF可能促进沙鼠肝泡球蚴组织血管新生。

Severe lumbar spinal stenosis combined with Guillain-Barré syndrome: A case report

BACKGROUNDGuillain-Barré syndrome (GBS) is a rare disorder that typically presents with ascending weakness, pain, paraesthesias, and numbness, which mimic the findings in lumbar spinal stenosis. Here, we report a case of severe lumbar spinal stenosis combined with GBS.CASE SUMMARYA 70-year-old man with a history of lumbar spinal stenosis presented to our emergency department with severe lower back pain and lower extremity numbness. Magnetic resonance imaging confirmed the diagnosis of severe lumbar spinal stenosis. However, his symptoms did not improve postoperatively and he developed dysphagia and upper extremity numbness. An electromyogram was performed. Based on his symptoms, physical examination, and electromyogram, he was diagnosed with GBS. After 5 d of intravenous immunoglobulin (0.4 g/kg/d for 5 d) therapy, he gained 4/5 of strength in his upper and lower extremities and denied paraesthesias. He had regained 5/5 of strength in his extremities when he was discharged and had no symptoms during follow-up.CONCLUSIONGBS should be considered in the differential diagnosis of spinal disorder, even though magnetic resonance imaging shows severe lumbar spinal stenosis. This case highlights the importance of a careful diagnosis when a patient has a history of a disease and comes to the hospital with the same or similar symptoms.

郭军教授治疗特发性男性不育症的经验

男性不育症中,精液分析多种参数异常且无法找到明确病因的称为特发性男性不育症,其发病率不断提高,给国内甚至全球范围内家庭带来精神及经济负担。由于病因不明确,目前现代医学尚无有效治疗方法。传统中医药通过辨证论治在治疗特发性男性不育症时具有优势,郭军教授认为该病以肾脾两虚为本,为体内湿热形成奠定基础,患者久病无子嗣,肝气不畅则郁结,气血津液运行不通则夹血瘀湿热等有形实邪,另外怪病多痰。故对于特发性男性不育症,治法注重补泻兼施,扶正祛邪,补益脾肾为主,对于湿热、痰湿、瘀血则清热祛湿化痰,活血化瘀等,并举验案1例。
