严重胫腓骨下段骨折手术方法的选择

胫腓骨下段骨折多为高能量损伤，随着交通、矿业、建筑等行业发展，此类骨折数量也呈上升趋势。由于小腿下段解剖的特殊，此类骨折尤其复杂，往往伴有软组织的损伤、缺损，造成局部软组织坏死、骨外露、感染。临床治疗中存在着很多困难，严重的开放骨折更存在着较高风险。不同类型的骨折，尤其是复杂骨折的手术治疗方法一直有不少争议。2000年1月-2008年12月，我院共收治A0分型43-A3型以上胫腓骨下段骨折98例，根据骨折的分型和特点，采用不同手术方法治疗，获得满意效果，现报告如下。     

对全自动生化分析仪7170机型样品盘2样本稳定性的探讨

日立7170全自动生化分析仪是集样品加样、定标、分析于一体的生化分析仪,该仪器的试剂盘1、2及样品盘2都有各自的制冷单元,样品盘2主要是存放标准液和质控样品,当样本放在自动生化仪上,其成分因温度、光线等原因而发生变质,或因为水分蒸发而浓缩时将可能出现测定错误,因而稳定性对于标准液和质控样本从设定后到预期反应这一段时期,和反复加样情况下尤其重要,而7170自动生化分析仪为标准液和质控样本装备有一制冷单元,以便保持一个适合稳定的环境来减少样本的变质和浓缩,

乳腺癌患者血清抵抗素、脂联素和瘦素水平及其临床意义

目的了解乳腺癌患者血清中抵抗素、脂联素、瘦素及血脂变化及临床意义。方法测定90例乳腺癌患者(48例未绝经,42例已绝经)及50名健康对照者血清抵抗素、脂联素、瘦素、空腹血糖(FBG)及血脂。结果乳腺癌患者脂联素及高密度脂蛋白胆固醇(HDL-C)显著低于对照组(P<0.01或P<0.05),抵抗素、瘦素、FBG及三酰甘油(TG)均明显增加(P<0.01或P<0.05)。但抵抗素、脂联素及瘦素在未绝经乳腺癌患者与健康对照组之间差异无统计学意义(P>0.05)。有淋巴结转移的乳腺癌患者抵抗素、脂联素及瘦素水平与无淋巴结转移乳腺癌患者间差异有统计学意义(P<0.01)。逐步回归分析,脂联素及HDL-C的降低,瘦素和抵抗素的升高将会增加罹患乳腺癌的风险。血清脂联素降低和瘦素的增加与乳腺癌患者淋巴结的转移呈现相关性。结论血清脂联素水平的降低和抵抗素及瘦素水平的升高是患乳腺癌的危险因素。血清中较低的脂联素和较高的瘦素水平是乳腺癌转移的危险因素。

Abstract：

Objective To investigate new cases of endemic cretinism in high-risk areas of Inner Mongolia, the prevalence of endemic goiter, the implementation of comprehensive measures, and to provide scientific basis for developing control strategies against iodine deficiency disorders (IDD). Methods In 2007 and 2008, a search for new cretin cases was conducted among children under the age of 10 in 11 historical serious epidemic cretinism prevalent areas of Songshan district, Keshiketeng qi, Kalaqin qi, Zhalaite qi, Zhuozi county,Liangcheng county, Qingshuihe county, Helin county, Dongsheng district, Zhungeer qi and Yinjinhuoluo qi. Three to 5 towns were selected in each qi(county, district) and 3 to 5 village primary schools were selected in each town.One hundred and twenty to 200 children aged 8 to 10 were selected in each school to inspect thyroid by B ultrasound and palpation and to test intelligence and urinary iodine. Two villages were selected in each town and 30 households were selected to determine urinary iodine of housewives and salt iodine. Results A total of 56 cases of suspected cases of endemic cretinism were found from the 11 counties but no case was confirmed. The goiter rate of children aged 8 to 10 was 5.2% (309/5922) by palpation and 4.3% (252/5922) by B-ultrasound. The median urinary iodine of children aged 8 to 10 was 241.5 μg/L, and urinary iodine was 100 to 300 μg/L, accounted 65.9%(3901/5920). Median urinary iodine of the 9 Qis(counties, districts) was in the range of 200 and 300μg/L.Higher than 5% of the 11 Qis(counties, districts) with urinary iodine lower than 50 μg/L was zero. Higher than 10% of the 11 Qis(counties, districts) with urinary iodine lower than 100 μg/L was 1. The median urinary iodine of housewives was 225.6 μg/L, and lower than 50 μg/L accounted for 2.2%(35/1597). Higher than 10% of the 11 Qis(counties, districts) with urinary iodine lower than 100 μg/L was 4. A total of 2109 households were investigated and 97.45%(2055/2109) of them ate iodized salt and 2.55%(54/2109) of them ate non-iodized salt. Conclusions In the 11 investigated counties, goiter rate of children has decreased to less than 10%, and no new cretin was found. It could be concluded that the fulfillment of prevention and control of IDD is effective. The iodine nutrition of children and women of childbearing age is in an adequate level. The coverage rate of iodized salt has maintained at a higher level, the sales network is sound, the salt price is reasonable and salt is easy to get and the children's intelligence is protected effectively. But, the health education about IDD is still weak, need to be reinforced.     

症状学研究在发作性疾病中的诊断价值

癫痫与心因性非癫痫发作(PNES)是发作性疾病的重要组成部分,诊断主要依靠发作症状及同步脑电图特征,临床上误诊率高。相关研究从症状学角度揭示了两者在发作前期、发作期和发作后期的差异,为更好地区分癫痫发作及PNES提供了可靠的依据。现就此类研究所发现的发作性疾病症状差异,主要是癫痫与PNES的差异予以综述,以揭示症状学潜在的研究价值。
