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.

麦胚提取物对辐射损伤修复的实验研究

目的 研究麦胚提取物对小鼠辐射损伤修复的调节和保护作用。方法 采用辐射前或辐射同时饲喂一定量的麦胚提取物，观察小鼠经X射线一次性全身照射后的临床症状、30d存活率、骨髓微核率、外周血白细胞总数在不同时间的变化。结果 与对照组(单纯照射)比较，饲喂麦胚提取物可使小鼠的头面部皮肤、小肠黏膜、肾脏损伤症状得到明显改善；30d存活率为86．17％(P＜0．01)，提高存活率41．79％，保护系数为1．72；骨髓微核率4．62‰；比对照组(12．14‰)降低(P＜0．01)；外周血白细胞总数在7，13，20，30d均显回升(P＜0.05，P＜0．01，P＜0．01，P＜0．01)。结论 麦胚提取物对小鼠辐射损伤修复有一定程度的调节和保护作用，对于辅助肿瘤放射治疗具有重要意义。     

痰液病理切片诊断老年性肺部恶性肿瘤

1979年以来,我们采用痰液切片的方法提高肺癌的诊断率,确诊老年性肺部恶性肿瘤23例,漏诊3例。26例中,最小年龄60岁,最大年龄72岁,现报告如下: 方法一、标本采集 1.取清洁带盖的广口瓶(100ml左右)加入组织固定液(95％酒精或其它固定液)30～50ml,令患者深咳,痰液赶入瓶内(留夜间、次日痰液,尽量多收集一些为好)。 2.或取清洁带盖广口瓶,令患者深咳嗽晨痰数口入瓶内。立刻送病理室,沿瓶壁加入适量固定液。     

锅炉噪声分析及其防护评价
