Emergency endovascular repair of iliac artery rupture caused by post-stenting angioplasty with an endograft

I liac artery rupture is a rare complication of post-stenting angioplasty and can lead to massive life-threatening haemorrhage. Conventional surgery can not repair the damaged vessel easily and may cause substantial blood loss and high operative morbidity and mortality. We report our experience with a self-expanding covered endoprosthesis for endovascular repair of the rupture of an iliac artery caused by stenting angioplasty.

Characteristics of the Bibliometric Indexes of Chinese Core Journals on Environmental and Occupational Medicine

This paper investigated the current characteristics and changing trends of major journals on Chinese environmental and occupational medicine in order to promote the development of these journals. This study focused on the seven core journals in the area of environmental and occupational medicine listed on the Chinese Scientific and Technical Journal Citation Reports (2008 version). These journals were China Occupational Medicine, Chinese Journal of Industrial Hygiene and Occupational Diseases, Chinese Journal of Industrial Medicine, Industrial Health and Occupational Diseases, Journal of Environment and Health, Journal of Environmental and Occupational Medicine, Occupation and Health. Various observations were based on data from www. cnki.net and Chinese Scientific and Technical Journal Citation Reports (2008 version), including cover of the journal, issue period, exposure to the internet, level of open source, impact factor, cited half-life, web immediacy index and rate of downloads per year. The outcomes showed that in appearance, the overall characteristics were continuous improvement of the covers, issue period, and moving toward the internet. In terms of contents, all factors had been improving.Nevertheless the level of influence was not very stable. The use of internet and the level of resource openness still have a long way to go to meet the international standard. There is still a huge gap for improvement. The contents and the appearance both need to be improved to serve the ever developing environmental and occupational medicine career.     

弥漫性大B细胞淋巴瘤中CD40L的表达及意义

目的探讨弥漫性大B细胞淋巴瘤（DLBCL）组织中CD40L表达与DLBCL预后间的关系及意义。方法免疫组织化学法检测27例弥漫性大B细胞淋巴瘤、20例淋巴结反应性增生组织中CD40L的表达。结果（1）DLBCL中CD40L过度阳性率（25．93％）显著低于淋巴结反应性增生（63．64％），P〈0．05。（2）CD40L在Ⅲ、Ⅳ期DLBCL过度阳性率（14．29％）低于Ⅰ、Ⅱ期（38．46％），P〈0．05。CD40L过度阳性率在有结外浸润DLBCL（11．76％）低于无有结外浸润DLBCL（40％），P〈0．05。（3）DLBCL患者CD40L的过度阳性率与远处转移、临床分期均显著相关，P〈0．05。结论（1）CD40L过度阳性率与结外器官浸润及临床分期密切相关，其可能作为判断DLBCL侵袭性及预后的指标。（2）DLBCL中CD40L表达的减少可能是影响其发病的因素之一。     

中鼻道及其周围结构的解剖学观测

对耳轮过度前突畸形的整复

对耳轮过度前突为对耳轮的角度过锐，致使耳轮的位置相应后移，表现为与招风耳完全相反的畸形。畸形虽不十分明显，但影响美观。自１９９２年４月开始应用患侧耳廓软骨和耳后皮瓣对５例患者８只外耳进行治疗得到满意效果。认为文中所述方法是矫正对耳轮过度前突畸形的良好方法。     

二乙基二硫代氨基甲酸钠驱镍作用的实验研究

本文用大鼠研究了带-SH基的二乙基二硫代氨基甲酸钠(Dithiocarb,简称Na-DDC或称铜试剂)和不带-SH基的新螯合剂(H-73-10)的驱镍作用。结果表明,Na-DDC对羰基镍(Ni(CO)_4〕的驱镍作用明显优于H-73-10;与此相反,H-73-10对硝酸镍〔Ni(NO_3)_2〕染毒大鼠的驱镍作用却明显优于Na-DDC。

Ethylene oxide does not extinguish the osteoinductive capacity of demineralized bone: A reappraisal in rats

We examined the influence of ethylene oxide (EO) and gamma irradiation on the osteoinductive capacity of demineralized bone. Demineralized bone powder prepared from Wistar rats was exposed to EO (55 °C or 40 °C) or gamma irradiation (25 KGy) or was preserved in ethanol. Sterilely-prepared bones served as controls. The powder was packed in a gelatin capsule and implanted for 6 weeks in muscles of 6-week-old female rats. Exposure of demineralized bone particles to EO 55 °C resulted in an almost complete loss of osteoinductivity. Irradiated bones lost about 40% of their osteoinductive capacity, while sterilization with EO at 40 °C resulted in only a slight alteration of the osteoinductivity, as assessed by the recovered weight ratio, calcium content, alkaline phosphatase activity measurements and histo-morphometry. Ethanol treatment had no influence on the new bone yield when compared to controls.

As EO exposure at 40 °C is a true sterilization procedure, it can be recommended in a clinical setting for its small effect on osteoinductive capacity as assessed experimentally in rats.
