Purpose: The purpose was to compare the effectiveness of MDCT reconstruction methods that improve detectability for detecting the renal arteries in patients undergoing laparoscopic nephrectomy irrespective of the ability of the radiologist. Methods: 128 patients with left nephrectomy and either one or multiple renal arteries were enrolled. Radiologists with varying levels of expertise (5 board-certified and 3 non-certified) interpreted all MDCT images, including axial, VR and MIP images, independently and determined the numbers of renal arteries. The interpretation times, sensitivity, specificity and diagnostic accuracy rates were analyzed. A receiver operating characteristic analysis was used to compare the results from the various reconstruction methods. Results: At surgery, there were 156 arteries: 101 donors had one renal artery and 27 had multiple arteries. The interpretation time for board-certified radiologists was shorter than that for non-certified radiologists, and the interpretation time using MIP images was significantly shorter than that of using the other reconstruction methods. The sensitivity, specificity and diagnostic accuracy on axial images were significantly higher than those on other images. The average Az value for detection of the numbers of renal arteries using axial images was higher than that of using other images. Conclusion: MDCT is helpful in reviewing the numbers of donated renal arteries for radiologists with different levels of expertise, and different types of reconstructions.

Journal of Pharmaceutical Analysis 2004年第1期16卷 67-70页

作者：刘恩岐 shuji Kitajima Masatoshi Morimoto Laboratory Animal Center Center for Laboratory Animals

Objective To create transgenic rabbits by microinjecting human apolipoprotein A-Ⅱ (apoA-Ⅱ) gene into one-cell embryos, to study apoA-Ⅱ gene function on plasma lipoprotein metabolism and atherosclerosis. Methods Superovulation and synchronization of estrus were induced in female Japanese White Rabbits by injecting hormone, then mating with male. After collected the fertilized eggs, the human apoA-Ⅱ gene was microinjected into the male pronucleus of eggs. The injected eggs were transferred into recipient female rabbits. Last, extract DNA from the new borns ear and determine whether the newborns were transgenic by polymerase chain reaction (PCR) or Southern blot analysis. Results A total of 822 embryos with microinjection of human apoAⅡ gene were implanted into 28 recipient rabbits. The number of surviving newborns was 37. 3 transgenic positive surviving founders were found with human apoA-Ⅱ.

BACKGROUND Colorectal neuroendocrine carcinoma (NEC) is a rare tumor that demonstrates aggressive growth pattern with ingrowth into the tract, metastasis to the other organs, and invasion to the surrounding organs;these clinical characteristics result in poor prognosis. Surgical resection appears as an effective approach;however, because it is difficult to accurately diagnose NEC during the early stage and owing to its aggressive growth pattern, development of a reliable standard chemotherapy regimen and management strategies are essential. CASE SUMMARY Here, we report the case of patient with NEC showing an aggressive growth pattern that resulted in the rupture of the tumor to the outside the colon after stenting of the internal colonic stenosis. In addition, the tumor invaded into the duodenum, thereby causing duodenal stenosis that required an additional stent in the duodenum. This aggressive growth pattern is one of the main features of the NEC that is different from adenocarcinoma. To clarify the clinical characteristics, we reviewed 60 recently reported cases, including data on tumor location, size, treatment, and prognosis. CONCLUSION We consider that the information presented here is of great significance for the diagnosis, treatment, and management of symptoms of the patients with NEC.

19世纪上半叶,中国人口出现了一些值得注意的现象,刘翠溶指出：“我们虽然也看到1750年轮的平均死亡年龄较以前的年轮为低,由于受家族记录断限的限制,我们并不能肯定死亡率的确是在十九世纪逐渐增高。如果真的是如此,那么,死亡率的增高、未婚率的提高和生子率的略降,竟然在时间上巧合,都是发生在清代由盛转衰之际。这是值得注意的人口现象。”

在单纳米晶和系综水平上探测有机-无机杂化钙钛矿纳米晶的分子结构对于理解其与尺寸相关的光电特性以及纳米晶体组装机制至关重要,但目前实现该探测依然存在很大的挑战性.本文首次证明飞秒和频振动光谱可以提供一种高灵敏的探测工具用于探测单纳米晶上与玻尔直径(约10 nm)相当的纳米晶分子结构.利用(R-MBA)PbBr_(3)和(R-MBA)_(2)PbI纳米晶(MBA:甲基苄胺)中苯基的光谱特征来监测和频信号,发现在系综水平上,和频谱图在3067(±3)cm(v模)处有一个很强的共振峰,在3045(±4)cm^(−1)(v模)处有一个弱的肩膀峰;而在单纳米晶水平上,主要由v模和在3025(±3)cm^(-1)处的v模组成.单纳米晶水平的纳米晶颗粒倾向于平躺在表面.而随系综数目和平均尺寸的增加,纳米晶逐渐竖立起来.这一发现可能为依赖于纳米晶尺寸的光物理性质和光致发光闪烁动力学的结构起源提供有价值的信息.

AIM To define clinical criteria to differentiate eosinophilic gastrointestinal disorder(Eo GD) in the esophagus. METHODS Our criteria were defined based on the analyses of the clinical presentation of eosinophilic esophagitis(Eo E), subepithelial eosinophilic esophagitis(s Eo E) and eosinophilic esophageal myositis(Eo EM), identified by endoscopy, manometry and serum immunoglobulin E levels(s-Ig E), in combination with histological and polymerase chain reaction analyses on esophageal tissue *** In five patients with Eo E, endoscopy revealed longitudinal furrows and white plaques in all, and fixed rings in two. In one patient with s Eo E and four with Eo EM, endoscopy showed luminal compression only. Using manometry, failed peristalsis was observed in patients with Eo E and s Eo E with some variation, while Eo EM was associated with hypercontractile or hypertensive peristalsis, with elevated s-Ig E. Histology revealed the following eosinophils per high-power field values. Eo E = 41.4 ± 7.9 in the epithelium and 2.3 ± 1.5 in the subepithelium; s Eo E = 3 in the epithelium and 35 in the subepithelium(conventional biopsy); Eo EM = none in the epithelium, 10.7 ± 11.7 in the subepithelium(conventional biopsy or endoscopic mucosal resection) and 46.8 ± 16.5 in the muscularis propria(peroral esophageal muscle biopsy). Presence of dilated epithelial intercellular space and downward papillae elongation were specific to Eo E. Eotaxin-3, IL-5 and IL-13 were overexpressed in Eo *** Based on clinical and histological data, we identified criteria, which differentiated between Eo E, s Eo E and Eo EM, and reflected a different pathogenesis between these esophageal Eo GDs.
