Clinico pathologic analysis of 1503 thyroid tumors]

A clinicopathologic analysis of 1503 thyroid tumors was conducted revealing 82.9% of benign and 17.8% of malignant lesions. The most common type of benign tumor was simple adenoma (62.1%) and of malignant tumor, papillary adenocarcinoma (52.5%). The malignant to benign tumor ratio was 1:4.8. The male to female sex ratio was 1:2.6 in the malignant and 1:3.8 in the benign tumors. The overall 5- and 10-year survival rates for all cancers were 67.7% and 47.6%, respectively. It is suggested that the follicular carcinoma could further be divided into well differentiated (papillary and follicular), poorly differentiated (including squamous cell carcinoma) and undifferentiated types.     

脑梗死患者血浆氧化低密度脂蛋白与一氧化氮、假性血友病因子及血浆颗粒膜蛋白的关系研究

目的探讨动脉粥样硬化性脑梗死患者血浆氧化低密度脂蛋白与血管内皮损伤及血小板活化程度的关系。方法用酶联免疫吸附测定（ELISA）的方法检测49例脑梗死患者和50例相匹配的对照组血浆氧化低密度脂蛋白（OX-LDL）、血管性假血友病因子（VWF）、血浆颗粒膜蛋白（GMP-140）水平，同时用硝酸还原酶比色法测定血清一氧化氮（NO）水平，并把、VWF、GMP-140、NO与OX-LDL作相关分析。结果脑梗死组血浆OX-LDL、、VWF、GMP-140明显高于对照组（t=2．91，P〈0．01；t=3．94，P〈0．001；t=2．08，P〈0．05），而脑梗死组血清NO水平明显低于对照组（t=4．02，P〈0．001）；相关分析表明血浆OX-LDL水平与血清NO水平呈负相关（r=-0．204，P〈0．05），与血浆懈呈正相关（r=0．60，P〈0．01），与血浆GMP-140呈正相关（r=0．430，P〈0．01）。结论脑梗死患者的血浆OX-LDL明显增高，而OX-LDL增高可能是脑梗死的危险因素。     

新政周岁:新乡医改连环扣

一年前。意图以医改试验牵动下一轮国企改制的新乡市政府，以及梦想着完善大生命产业链最后一环的华源集团。在河南新乡联手导演了一出轰轰烈烈的五家医院整体“捆绑改制”。本刊当时曾以“闪击战”形容那场医改风暴的强劲势头。如今当潮头已过，逐浪而来的是浊流击岸，还是一碧万顷?     

从"集体哗变"看文化再造

去年春节,陈振强这个名字突然出现在公众的视野里,并频现报端。此前,提到南京市第一医院,人们只知道它的心脏手术十分著名,作为该院心外科“二陈”之一的陈振强则鲜为人知。陈振强一夜成名的原因是:与自己的手术团队集体“改嫁”到江苏省中医院,也即媒体所述的“南京市第一起医疗专家集体哗变案”,而陈振强正是此案的“策反者”!10个月后,“哗变”事件又在厦门眼科中心上演,这次的主角是大名鼎鼎的“福建眼科第一刀”洪荣照。因为与医院改制后的新东家存在“理念差异”,洪荣照负气带走了78名医疗骨干。     

The prevalence of LRRK2 Gly2385Arg variant in Chinese Han population with Parkinson's disease.

We conducted a case-control study to determine the prevalence of the LRRK2 Gly2385Arg variant in patients with Parkinson's disease in Han population in mainland China. Heterozygous LRRK2 Gly2385Arg variant was identified in 14 of 235 patients with Parkinson's disease (5.69%), but not in 214 unrelated healthy controls. Multivariate analysis indicated the frequency of Gly2385Arg variant in the female patients with early age at onset is higher than their male counterparts. The founder haplotype analysis showed the variant carriers shared the same founder. Clinically, the LRRK2 Gly2385Arg carriers presented with classical Parkinson's disease symptoms. Our study indicates that the LRRK2 Gly2385Arg variant is a potential ethnic-specific genetic risk factor of Parkinson's disease within Chinese Han ethnicity.

美国前总统克林顿再接受心脏手术2005年4月《商业周刊》美国前总统克林顿办公室3月8日宣布,克林顿将于3月10日再接受一次心脏手术,以解决上次手术留下的疤痕组织及胸腔积液。克林顿对此事表现得很轻松,他说,在手术的前一天,他还要按计划与美国前总统老布什一起去打高尔夫球。克林顿曾于去年9月在纽约哥伦比亚大学医学中心(基督教长老会医院)接受过一次左心室的搭桥手术,当时手术进行得很成功,而此次手术是为了解决上次手术出现的并发症问题。这次手术仍然在哥伦比亚大学医学中心进行。据该医院的有关负责医生说,手术的风险很小,只需要采用     

愿《中国卫生产业》曲高和不寡

参加中国卫生经济学会第十次年会时，有幸拜读贵刊，从此便与贵刊结下不解之缘。贵刊立意高，选题新，尤其是每期的“卷首语”篇篇有新意，句句皆精彩，令人百看不厌，不愧为“点睛”之笔。在当今竞争激烈的期刊市场上，贵刊能不媚俗、颇有清奇、俊秀之感。从贵刊去年第八期的“读者构成表”上看，贵刊读者以高端人士为主体，应该说这是一笔宝贵的财富。

Effect of intravenous sedation on the outcome of transvaginal oocyte retrieval: a comparative study of propofol- and methohexital-based techniques

This study retrospectively compares patients who underwent outpatient transvaginal follicle aspiration with either a propofol- or methohexital-based intravenous sedation technique. Data collected from patient charts (n = 212) over a 46-month period were analyzed to determine the effects of each sedation technique on procedure and recovery times, number of retrieved ova, as well as rates of nausea, fertilization, cleavage, pregnancy, and delivery. All patients were included in the study, regardless of age or diagnosis. procedure time was lower in the propofol group (51 t 18 min) than in the methohexital group (61 I 20 min) (p > 0.01). Patients in the methohexital group (139 2 51 min) spent more time in the recovery room than did those in the propofol group (71 ? 34 min) (p > 0.01). The nausea rates were significantly lower in the propofol group compared with the methohexital group (1.9% vs. 14.4%, respectively) (p > 0.02). Fertilization rate in the propofol group was 77.7% and was 62.9% in the methohexital group (p > 0.01). The numbers of retrieved ova and the cleavage rates were similar in both groups. The rate of pregnancy in patients sedated with propofol (46.1%) was higher than the methohexital group (26.9%) (p > 0.02). Delivery rate was 38.5% in the propofol group and 20.6% in the methohexital group (p > 0.02). In summary, propofol intravenous sedation for transvaginal follicle aspiration was associ- ated with an improved outcome. Pregnancy and delivery rates were higher while nausea, an unpleasant side effect, was sharply reduced.
