Heterotopic transplantation of bone marrow demonstrated that the content of stromal precursor cells capable of hemopoietic
microenvironment transfer does not depend on thymus function. Thymectomy of bone marrow donors involves a decrease in the
size of foci formed in young donors and an increase in old recipients. The results indicate a thymus-dependent regulation
of proliferation of stromal precursors and/or their factor-sensitive category, determining the proliferation of recirculating
stem hemopoietic cells. The size of ectopic hemopoiesis focus depends on the age of recipient. Transplantation of syngeneic
thymus under renal capsule of thymectomized mice abolished the effect of thymectomy. Osteogenic activity of stromal precursors
correlates with the age of bone marrow donors.

肿瘤相关基因Cap43在胰腺癌中的表达及意义 总被引:4,自引:0,他引:4
目的研究肿瘤相关基因Cap43在胰腺癌组织中的表达情况,探讨其对胰腺癌的诊断价值。方法收集1999年4月~2002年8月长海医院外科手术切除胰腺癌标本和癌旁正常组织33例,诊断均由病理证实。男性22例,女性11例,年龄30~73岁,平均58.1岁。所有组织标本按肿瘤、癌旁(正常)配对。采用RT-PCR和Northern杂交方法研究Cap43 mRNA表达情况。结果 RT-PCR结果显示,Cap43在肿瘤组织中表达显著上调,其在肿瘤组织和癌旁正常组织的扫描值分别为4 033±1 986和2 244±1 145,有显著差异(P<0.001)。Northern杂交亦显示Cap43在肿瘤组织中表达显著上调,相同病例的RT-PCR结果与Northern杂交的结果有较好的一致性,经回归分析,没有显著性差异(P>0.1)。结论 Cap43在胰腺癌组织中呈显著高表达,其有可能成为胰腺癌早期诊断的重要标志物。 相似文献

Telomerase activity was measured in spleen colonies, in progeny of individual 9-day-old splenic CFU formed by the bone marrow from normal (physiological aging) and thymectomized mice. Cells of spleen colonies expressed telomerase activity. No correlation was found between telomerase activity in spleen colony cells and age of animals. Thymectomy of bone marrow donors had no effect on telomerase activity. Our results suggest that the thymus plays a role in cell aging.Translated from Byulleten Eksperimentalnoi Biologii i Meditsiny, Vol. 138, No. 11, pp. 567–569, November, 2004 相似文献

Intussusception in adults is a rare cause of abdominal pain. Unlike its paediatric counterpart, intussusception in adults is associated with obvious pathology. We describe a case of ileocolic intussusception extending to the splenic flexure. We were able to reduce the intussusception partially and pedicle was stapled carefully. The specimen was delivered through a small incision and right hemicolectomy was performed adhering to oncological principles. We recommend laparoscopic-assisted surgery is considered for adult intussusceptions. 相似文献

Background
Continuous intrathecal drug delivery has been shown in open studies to improve pain and quality of life in those with intractable back pain who have had spinal surgery. There is limited data on long term effects and and even less for patients with mechanical back pain without prior spinal surgery. 相似文献8.

PAQR3, also known as RKTG (Raf kinase trapping to Golgi), is a member of the progestin and adipoQ receptor (PAQR) family. The role of PAQR3 as a tumor suppressor has recently been established in different types of human cancer in which PAQR3 exerts its biological function through negative regulation of the oncogenic Raf/MEK/ERK signaling. Multiple studies have found that PAQR3 downregulation frequently occurs in human cancers and is very often associated with tumor progression and shortened patients’ survival. Moreover, restoring the expression of PAQR3 could induce apoptosis and inhibit proliferation and invasiveness of cancer cells. Downregulation of PAQR3 by oncogenic microRNAs has also been reported. In this review, we summarized current knowledge concerning the role of PAQR3 in tumor development. To our knowledge, this is the first review on the role of this novel tumor suppressor. 相似文献
