荧光定最PCR法检测母乳巨细胞病毒感染的研究

目的了解母乳人巨细胞病毒(HCMV)感染状况.方法应用荧光定量PCR(FQ-PCR)法检测390份母乳中HCMV-DNA含量,其中236份母乳配对与患儿血液中HCMV-DNA含量作一定分析.结果可疑或确诊HCMV感染患儿母亲母乳HCMV-DNA阳性率达71.28%,HCMV-DNA阳性母乳喂养的婴儿,其血或尿HCMV-DNA阳性率明显高于HCMV-DNA阴性母乳喂养的婴儿.结论HCMV感染母乳是婴儿获得性感染的主要途径.     

跖跗关节骨折脱位诊治体会

随着交通、工伤事故增多，跖跗关节（Lisfrane关节）损伤明显增多。由于跖跗关节为中足一复杂的复合性结构，处于足弓顶部，在步态中支撑体重，它的损伤、破坏常严重影响步行或致足畸形，此类损伤在临床中并不少见，易漏诊，因其结构复杂，在诊治中易出现失误。我院2001年6月～2005年6月共收治跖跗关节骨折脱位12例，现分析总结如下。     

PET/CT在评价及观察大鼠肺癌放疗效果中的应用

Objective The aim of this study was to understand the role of PET/CT in monitoring the therapeutic effect of radiotherapy (RT) on lung cancer with Wistar rats. Methods Thirty Wistar in-bred strain rats (6-8 weeks, weighed 180-280 g, female, ordinary) were made into Lewis pulmonary tumor model rats. 18F-fluorodeoxyglucose (FDG) PET/CT was performed when tumor reached 1.5-2.0 cm in greatest diameter (4-6 weeks) as a baseline. In order to get the optimal time point of PET/CT for moni-toring RT effect in rat cancer model, PET/CT was performed at the 3rd day, 1st, 2nd, 3rd, and 4th week after giving single dose of 5 Gy to each rat. Standardized uptake values (SUV) from FDG PET were measured and rats were sacrificed at different time point for validation. Besides, the expressions of glucose transport1 (Glut1) in tumor tissue were studied using immunohistochemistry. The level of tumor cell apoptosis, degra-dation, and necrosis were observed. SPSS 11.0 software was used for data analyses. Results A negative correlation of SUV uptake and time after RT and negative correlation of Glut1 expression and time after RT were observed in rat tumors, respectively. Positive correlation of SUV uptake and Glut1 expression in rat tumors was observed (Spearman rank correlation test, rs = 0.97, P < 0.01). Before RT, the SUV in rat tumor was 1.28 ± 0.31 and was decrease to 1. 00 ± 0.23 at the 3rd day and 0.18 ± 0. 10 at the 4th week after RT (F=15. 126, P<0.05). Before RT, the Glut1 in rat tumor was 0.2558 ±0.03 and was decrease to 0. 2320 ± 0. 01 at the 3rd day and 0. 1320±0.04 at the 4th week after RT. The amounts of tumor cell apopto-sis, degradation, and necrosis increased with time after RT. Conclusion Though FDG PET could monitor the therapeutic effect at the 3rd day after giving single dose of RT to rat lung tumor model, the optimal time was the the 4th week after treatment.     

完全型房室间隔缺损合并法洛四联症心内矫正术

目的总结心内矫正术治疗完全型房室间隔缺损合并法洛四联症(CAVSD-TOF)的经验. 方法从1985年1月至2002年5月,共行CAVSD-TOF心内矫正术12例,年龄6～16岁(11.1±2.8岁),采用右心房、右心室纵切口,前7例采用三片法补片,后5例用二片法补片修补房室间隔缺损,左侧房室瓣裂隙采用间断缝合,右心室流出道用跨瓣补片加宽. 结果术后早期死亡4例,前7例死亡3例,后5例死亡1例,死亡原因为严重低心排血量3例,灌注肺1例.长期随访6例,随访时间3个月至13.5年,无任何症状,NYHA心功能Ⅰ级或Ⅱ级. 结论 CAVSD-TOF采用右心房、右心室纵切口,二片法补片修补房室间隔缺损,常规间断缝合左侧房室瓣裂隙,跨瓣补片加宽右心室流出道能取得较良好的效果.

UVA对人角质形成细胞的氧化损伤作用

①目的　探讨紫外线A(UVA)对人角质形成细胞氧化损伤的机制。②方法　用 5J/cm2 UVA照射角质形成细胞 ,酶生化法检测活性氧 (ROS)的含量及超氧化物歧化酶 (SOD)、谷胱甘肽过氧化物酶 (GSH PX)活性的变化 ,流式细胞仪测定紫外线对角质形成细胞凋亡的影响 ,原位杂交技术观察 p2 1mRNA的变化 ,并与非照射组比较。③结果　与对照组比较 ,UVA照射组ROS含量升高 (t =113.6 8,P <0 .0 0 1) ,SOD、GSH PX活性下降 (t =5 7.2 3、19.0 4 ,P <0 .0 0 1) ,细胞凋亡率升高 (t=5 3.2 8,P <0 .0 0 1) ,p2 1mRNA表达增强。④结论　UVA对人角质形成细胞的损伤与氧自由基生成增多及细胞抗氧化能力抑制有关
