Background The value of intravascular ultrasound （IVUS） imaging in patients with replacement of the ascending aorta for acute type A aortic dissection （AD） is unknown. The purpose of this study was to assess the potential use of IVUS imaging in this setting. Methods From September 2002 to July 2005, IVUS imaging with a 9 MHz probe was performed in a series of 16 consecutive patients with suspected or established AD. This study focused on 5 of them with replacement of the ascending aorta for acute type A AD. Among these 5 patients, other imaging modalities including aortography, spiral computed tomography, magnetic resonance imaging and transesophageal echocardiography were performed in 5, 3, 3 and 1 patients, respectively. Results There were no complications related to IVUS imaging. For the replaced graft, as other imaging modalities, IVUS could identify all 5 grafts, the proximal and the distal anastomoses, and the ostia of the reimplanted coronary arteries. In 2 cases, IVUS detected 2 peri-graft pseudo-aneurysms （1 per case）, which were also detected by magnetic resonance imaging but omitted by aortography. For the residual dissection, IVUS had similar findings as other imaging modalities in detecting the patency （5/5）, the longitudinal and the circumferential extent, the thrombus （4/5）, the recurrent dissection （1/5） and an aneurysm distal to the graft （5 in 4 patients）. However, it detected more intimal tears and side branch involvements than other imaging modalities （15 vs 10 and 3 vs 1, respectively）. Conclusions In following-up patients with replacement of the ascending aorta for acute type A AD, IVUS imaging can provide complete information of the replaced graft and the residual dissection. So, IVUS imaging may be considered when the four current frequently used imaging modalities can not supply sufficient information or there are some discrepancies between them.

A method based on regression modeling was developed to discern the contribution of component chemicals to the toxicity of highly complex, environmentally realistic mixtures of disinfection byproducts（DBPs）. Chemical disinfection of drinking water forms DBP *** of concerns about possible reproductive and developmental toxicity, a whole mixture（WM） of DBPs produced by chlorination of a water concentrate was administered as drinking water to Sprague–Dawley（S–D） rats in a multigenerational study. Age of puberty acquisition,i.e., preputial separation（PPS） and vaginal opening（VO）, was examined in male and female offspring, respectively. When compared to controls, a slight, but statistically significant delay in puberty acquisition was observed in females but not in males. WM-induced differences in the age at puberty acquisition were compared to those reported in S–D rats administered either a defined mixture（DM） of nine regulated DBPs or individual DBPs. Regression models were developed using individual animal data on age at PPS or VO from the DM study. Puberty acquisition data reported in the WM and individual DBP studies were then compared with the DM models. The delay in puberty acquisition observed in the WM-treated female rats could not be distinguished from delays predicted by the DM regression model, suggesting that the nine regulated DBPs in the DM might account for much of the delay observed in the WM. This method is applicable to mixtures of other types of chemicals and other endpoints.

East Asians are the most populous race in the world and their health status is an important global *** with Caucasian populations, East Asian patients have a different benefit/risk ratio when using antithrombotic treatment. Despite this observation, treatment strategies in East Asian patients are mostly based on the American and European guidelines. Despite a lower platelet inhibitory response to clopidogrel, East Asian patients show a similar or even a lower rate of ischemic event occurrence and higher bleeding risk compared with Caucasian patients. For potent P2Y_(12) inhibitors(ticagrelor and prasugrel),East Asian patients have shown less favorable net clinical benefits compared with Caucasian patients,which may be related to differences in pharmacokinetic/pharmacodynamic profiles and therapeutic zone of antiplatelet effect. This updated consensus mainly focuses on state-of-the-art and current controversies in the East Asian population. In addition, when East Asian patients are administered potent P2Y_(12) receptor inhibitors, the strategies and ongoing trials to overcome the related hurdles are discussed.

AIM To investigate the relationship between post-liver transplantation(LT) glycemic control and LT outcomes. METHODS A qualitative systematic review on relevant prospective interventions designed to control glucose levels including insulin protocols. Studies investigating an association between glycemic control and post-LT outcomes such as mortality, graft rejection, and infection rate were reviewed. Pub Med, EMBASE, and other databases were searched through October 2016. RESULTS Three thousands, six hundreds and ninety-two patients from 14 studies were included. Higher mortality rate was seen when blood glucose(BG) ≥ 150 mg/dL(P = 0.05). BG ≥ 150 mg/dL also led to higher rates of infection. Higher rates of graft rejection were seen at BG > 200 mg/dL(P < 0.001). Mean BG ≥ 200 mg/dL was associated with more infections(P = 0.002).Nurse-initiated protocols and early screening strategies have shown a reduction in negative post-LT *** Hyperglycemia in the perioperative period is associated with poor post-LT outcomes. Only a few prospective studies have designed interventions aimed at managing post-LT hyperglycemia, post-transplant diabetes mellitus(PTDM) and their impact on post-LT outcomes.

背景:上消化道内镜检查是诊断和治疗上消化道疾病最常用的方法之一,为鉴别早期肿瘤病变提供了独特的机会。为了获得最佳高质量的上消化道内镜,良好的胃和粘膜的可视化非常重要。然而,泡沫、气泡和黏液常常阻碍其可见性,此外,还延长了手术的持续时间,影响了患者的耐受性和执行内镜医师的满意度。目前内镜医师在内镜检查中使用不同的术前药物,以减少泡沫、气泡和黏液的含量。目的:评价不同术前用药的疗效及它们在上内镜检查中增强粘膜可视性和安全性的联合作用方法:单中心、前瞻性、双盲（患者和医生）、随机研究。共有250名患者转诊至东南大学附属中大医院,在消化科门诊和住院接受选择性胃镜检查。参与者被随机分配接受五种药物中的一种:A组:西甲硅油,B组:西甲硅油加链霉蛋白酶,C组:二甲硅油,D组:二甲硅油加链霉蛋白酶,E组:链霉蛋白酶。在内窥镜检查前15到30分钟,患者接受了指定组的术前准备。在内镜检查中,对食管、胃体和胃窦的粘膜可见度进行评估,可见度评分分为1-3分。1=无气泡和轻微气泡（≤25%气泡）),无黏液,粘膜清晰可见;2=中等气泡（25%0%气泡）黏液薄层,但不遮挡视力;3=严重气泡（≥50%气泡）黏液遮挡视力。符合以下排除标准的患者被排除在外:急诊病例,以前接受过全胃切除术的患者,胃肠道出血,已知肿瘤或狭窄,对试验药物过敏,孕妇或哺乳期妇女。结果:将250例患者、122例男性患者和128例女性患者随机分为5组,每组50例。5组在年龄、性别和主要手术指征方面均无统计学意义。在食管部位,C组和D组总得分最高。而在胃体和胃窦部位,B组和D组有着更好的视觉效果。结论:为了获得上消化道的最佳视野,使其不存在过多的气泡和黏液,建议在上消化道内镜检查前使用消泡剂（西甲硅油或二甲硅油）和溶黏液剂（链霉蛋白酶）。

这篇文章以一个挑鲜性的问题开头:是否存在真正的多元实值连续函数?这个问题可能看起来有点愚蠢,但实际上正是David Hilbert(希尔伯特)1900年在巴黎举行的第二届国际数学家大会上提出的23个问题之一。这些问题引领了20世纪很大一部分数学研究.Hilbert第13问题猜想存在连续函数f:I^(3)一→R其中I=[0,1],无法通过从R^(2)→R的连续函数的加法和复合表示出来,也就是说,不能用两个变量的连续实值函数的复合和加法来表示。证明Hilbert的猜想是错误的花了50多年的时间.这篇文章旨在讨论这个解决方法。
