血清CA153、CA125和CEA联合检测在乳腺癌诊断中的应用

Objective To study the clinical singificance of serum tumor markers (CA153, CA125 and CEA) in doagnosis of breast cancer. Methods Electrochemiluminescence immunoassay (ECLIA) was used to analyze serum levels of CA153,CA125 and CEA in 55 patients with breast canc-er (breast cancer group),20 patients with benign breast lesions (benign breast lesion group) and 20 healthy controls (healthy control group). Results The levels of CA153, CA125 and CEA in breast cancer group were significantly higher than those in healthy control group (P<0.05); the levels of CEA and CA153 in breast cancer group were significantly higher than those in benign breast lesion group (P<0.05);the level of CA153 in postoperative patients was statistically lower than that in pre-operative patients (P<0.05);the levels of CEA and CA153 in breast cancer patients with stage Ⅲ and Ⅳ were significantly higher than those in healthy controls (P<0.05); the level of CA153 with stage Ⅲ and Ⅳ was higher than that in ones with stage Ⅰ and Ⅱ. The combined dection of CA153, CA125 and CEA in breast cancer patients increased the experimental sensitivity to 53.8% and specific-ity to 83.3%. Conclusion Detections of CA153,CA125 and CEA contribute to diagnosis of breast cancer. CA153 and CEA are of clinical practical value in differential diagnosis of benign and malignant breast tumor,monitoring of course of breast cancer.     

福建虫媒病毒研究概况

虫媒病毒（Arbovirus）由吸血昆虫（蚊、蜱、虻、蠓、蛉等）通过叮咬将病毒传播给人与动物,病毒在媒介体内繁殖、传代,引发人兽共患病。此类疾病常表现为发热、皮疹、出血和脑炎,侵犯皮肤、神经系统较多见。虫媒病毒引起的人兽共患病种类较多,近年备受关注。1950年全球仅发现35种虫媒病毒,2006年达538种。其中130余种可引起人兽共患病（主要为披膜病毒科、黄病毒科和布尼亚病毒科）,导致发热、皮疹和关节痛、出血热、休克等,严重者可致死;     

提高新生儿听力筛查效果的护理对策

通过对2003年11月至2004年lO月出生的新生儿进行听力筛查和护理,认为加强操作规范和护理,可有效减少筛查的假阳性,提高筛查通过率。     

CD62P和CD63在糖尿病肾病的临床应用

美国糖尿病联合会的新分类法认为2型糖尿病(T2DM)是最常见的糖尿病。笔者应用流式细胞仪及特定蛋白分析仪检测T2DM患者外周血血小板的活化程度及尿中微量球蛋白(β2M)的表达，探讨血小板表面α-颗粒膜蛋白(CD62P)和血小板溶酶体α-颗粒膜蛋白(CD63)对早期诊断T2DM肾损害的临床价值。     

冠心病患者PTCA前后外周血CD11b、CD62P表达变化及意义

采用流式细胞仪检测23例健康体检者（对照组）及41例冠心病患者（观察组）,经皮冠状动脉腔内成形术（PTCA）术前72、2h、术后30min及24、72h外周血中性粒细胞和单核细胞表面CD11b、CD62P的表达。结果观察组患者外周血中性粒细胞和单核细胞CD11b平均荧光强度（MFI）和CD62P阳性细胞百分比较对照组明显升高。PTCA术后24hCD11b荧光强度和CD62P阳性细胞百分比较术前72、2h明显升高。血小板CD62P与中性粒细胞CD11b呈正相关（r=0．253）。认为PTCA术后中性粒细胞和单核细胞CD11b及血小板CD62P表达上调,且可作为反映PTCA后炎症反应和血栓形成状况的指标。     

Cks1在P27蛋白泛素化降解过程中的作用

在细胞分裂周期中，Cks1蛋白参与并促进P27蛋白泛素化降解，从而解除其对细胞周期蛋白激酶的抑制作用，促使细胞通过G1／S转折期。在大部分肿瘤细胞中Cks1蛋白表达上调，P27蛋白过多泛素化降解，Cks1蛋白参与并促进P27蛋白泛素化降解与细胞周期调控和肿瘤发生发展关系密切。本文综述了Cks1蛋白参与P27蛋白泛素化降解的基础和临床研究进展。

恶性肿瘤患者血清Kappa与Lambda轻链检测及临床意义

Objective To investigate the abnormal expressions of immunoglobulin light chains kappa(Igκ)and Lambda(Igλ)in malignant tumors.Methods The concentrations of the Igκ and Igλ in serum were measured by rat nephelometry in 60 cases of malignant tumors and 15 cases of healthy people.Results The liver tumor patients had a higher concentration of Igκ and Igλ in serum than normal people(P＜0.01).There wre not significant differences between the levels of Igκ,Igλ and κ/λ ratio in the stomach tumor,lung tumor,proctologic/colonic tumor,mammary tumor,oesophagus tumor and normal peoples(P＞0.05).Conclusion The measurment of Igκ,Igλ and κ/λ ratio in serum would be helpful for the diagnosis of the liver tumor.By continous observation with Igκ,Igλ and κ/λratio in serum could predict the development of disease.     

L-阿拉伯糖抑制兔子因喂养高糖高脂饲料引起的体内脂肪堆积

目的:本研究通过将唐传(厦门)生物科技有限公司生产的L-阿拉伯采用口服方法,喂服新西兰大白兔,同时用高糖高脂饲料喂养兔子,观察L-阿拉伯糖对抑制因为连续高糖高脂饲料引起的血脂紊乱和脂肪堆中的作用.为将L-阿拉伯糖应用到预防肥胖以及由此引发的并发症提供科学数据.方法:择体重在1.8-2.0kg范围新西兰大白兔32只,随机分为A,B,C组,每组8,其中A～C组均喂养高糖高脂饲料,D组喂普通饲料,同时A组按1.24g/d,B组按1.11g/d剂量口服L阿拉伯糖进行干预.实验持续3个月,实验结束,颈动脉取血扑杀兔子,分离血清采用贝克曼全自动生化仪检测血脂水平,包括总胆固醇(TC),甘油三脂(TG)水平,同时分离腹部脂肪和肾脏周围脂肪,称重并计算脂肪指数.结果:生化指标检测结果显示,口服L-阿拉们糖高剂量组的兔子TG水平比对照组低,差异显著(P<0.05),TC水平比对照组低17%,但没有达到显著性差异,脂肪指数结果证明,两个剂量组的兔子脂肪指数明显比实验对照组低,差异显著(P<0.05).结论:1.24g/d剂量的L-阿拉伯糖能够有效降低胆固醇和甘油二脂水平,同时能够有效抑制兔了体内脂肪堆积,减少脂肪指数.
