MiR-148a inhibits angiogenesis by targeting ERBB3

MicroRNAs (miRNAs) play an important role in carcinogenesis in various solid cancers including breast can-cer. Down-regulation of microRNA-148a (miR-148a) has been reported in certain cancer types. However, the biological role of miR-148a and its related targets in breast cancer are unknown yet. In this study, we showed that the level of miR-148a was lower in MCF7 cells than that in MCF10A cells. V-erb-b2 erythroblastic leukemia viral oncogene homolog 3 (ERBB3) is a direct target of miR-148a in human breast...     

社区健康教育干预促进鼻咽癌早期发现和防治的效果研究

目的　评价健康教育干预对鼻咽癌早发现和早治疗的效果。方法　在广州市天河区华乐社区的5 1 40 3名居民中开展为期 3年的社区健康教育干预。另选登峰社区 5 0 3 1 7名居民作为对照组 ,不采取任何干预措施。结果　干预后鼻咽癌患者初发鼻咽症状至确诊的持续时间缩短 ,居民鼻咽癌防治知识知晓率明显提高 (P <0 0 1 ) ,干预组的知晓率为 92 3 3± 6 3 8% ,明显高于对照组的 72 92± 1 7 64%。在华乐社区 5 1 40 3例有鼻咽症状的患者中检出鼻咽癌 1 96例 ,其中 ,5 3例为早期鼻咽癌 ,早诊率为 2 7 0 4% ,明显高于对照组的早诊率 9 2 1 %。结论　社区健康教育干预对鼻咽癌早发现和早治疗有积极的促进作用。     

X线、MSCT和MRI对主动脉夹层的临床运用对比研究

目的对比分析X线、MSCT及MRI在主动脉夹层（AD）中影像学特征,并评价其临床运用价值。方法 30例经手术或行DSA造影证实的AD患者,对其X线、MSCT及MRI检查影像资料进行分析,总结归纳其影像特点。结果 X线仅见AD的间接征象,而MSCT和MRI均能不同程度地显示真假两腔、内膜破口、内膜片及附壁血栓。结论 X线对AD只能提示诊断,而MSCT和MRI可作特异性诊断,并且MRI在显示AD的破口位置、无钙化的内膜片及附壁血栓时均优于MSCT,但对内膜及主动脉壁钙化和急危重者的检查MSCT优于MRI。     

运动预处理对大鼠心肌CuZn-SOD基因表达的影响

为探讨在高原或仿高原环境下高强度运动的心脏适应机制,通过动物实验模拟高原运动心脏,观察了心肌组织中CuZn-sODmRNA的表达情况.结果表明,在海拔5000米环境下,大鼠6%负重游泳10分钟,常压休息10分钟,重复3次,在运动后30分钟和24小时,心肌CuZn-SODmRNA的表达出现两个高峰,分别比对照组升高了47%和112%;而大鼠在单独低压氧环境下不运动,只在缺氧后30分钟时有CuZn-SODmRNA的表达增高.结果提示与经典的缺血预处理类似,在高原或仿高原环境下进行高强度训练,很可能是一种由心肌缺血和缺氧等因素所诱发的"运动预处理”现象.     

The remedial effect of soluble interleukin-1 receptor type Ⅱ on endometriosis in the nude mouse model

Objective： Recent studies have shown that the local expression of soluble interleukin （IL） -1 receptor type Ⅱ （slL-1 R Ⅱ ） in endometrial tissue of women with endometriosis is decreased, and the depression of IL-1 R Ⅱ was more significant in infertile women than that in fertile women with endometriosis. In this research, we investigated the remedial effect of slL-1-R Ⅱ administration on endometriosis in the nude mouse model. Methods： Nineteen nude model mice with endometriosis were randomly divided into three groups： group A was treated by intraperitoneal administration with only slL-1 R Ⅱ for two weeks, group B was similarly treated with only IL- 1, and group C （control） was administered saline. After 2 weeks, the size of the ectopic endometrial lesions was calculated, and the expression of vascular endothelial growth factor （VEGF） and B-cell lymphoma leukemia-2 （Bcl- 2） were detected by immunohistochemistry. The IL-8 and VEGF levels in the peritoneal fluid （PF） and serum were also measured by enzyme-linked immunosorbent assay （ELISA）. Results： The mean size of ectopic endometrial lesion did not differ between the three groups （P 〉 0.05）. Compared with the control, the expression of VEGF and Bcl-2 was significantly lower in group A, and higher in group B. In the three groups, the levels of IL-8 in the PF and serum were highest in group A, and lowest in group B. Conclusion： slL-1 R Ⅱ may suppresse hyperplasia of ectopic endometriosis, perhaps by reducing the expression of certain cytokines, such as VEGF, IL-8, and Bcl-2, which could provide a new clinical strategy for the treatment of endometriosis.

铋合剂与复方铋剂治疗胃溃疡的对比研究

经内窥镜证实的活动性胃溃疡的门诊病人76例(包括胃溃疡60例及复合溃疡16例)随机分成两组,分别给予铋合剂(MB)和复方铋剂(MBC)治疗,在6周疗程结束后2天内纤维内窥镜复查,判明疗效。结果发现胃溃疡MB组30例愈合者26例(86.7%),MBC组30例愈合者24例(80%);复合溃疡MB组8例愈合6例(75%),MBC组8例愈合5例(62.5%),两组疗效比较在统计学上均无显著性差异(P>0.05)。12例接受MB治疗的患者,在治疗前及疗程2周、6周末测试BUN、肌酐及PSP亦均无显著变化(P>0.05)。本文说明铋合剂治疗活动性胃溃疡与复方铋剂比较,同样有效;且铋合剂制备更简易,制剂稳定便于保存,未发现有副作用,值得推广。
