BACKGROUND:In recent years, with the in-depth research on thecharacteristics and functions of stem cells,stem cell research has become a hot research targeting thetreatment of a variety of diseases.OBJECTIVE:To summarize the research progress of human amnioticmesenchymal stem cells in the treatment of acute lung injury.METHODS:The PubMed and CNKI databases were searched by computerfor relevant literatures published from January 2000 to January 2017. The key words were mesenchymal stem cells, acute lung injury in Chinese and English,respectively.RESULTS AND CONCLUSION:As an important member of adult stem cells, human amniotic mesenchymal stem cells not only have the advantages and characteristics of most other stem cells, but also have unique advantages, such as these cells can be extracted from a vast of sources, require only non-invasive operations, and involve no violation of ethics. Human amniotic mesenchymal stem cells can be driven by inflammation reaction and homing to the damaged tissue, and be activated by inflammatory factors to secrete a variety of cytokines in a paracrine fashion, which inhibit neutrophils, macrophages and other immune cell migration and inhibit dendritic cell maturity, and reduce the proliferation of NK cells, B lymphocytes and T lymphocytes, and up-regulate anti-inflammatory cytokines and down-regulate proinflammatory cytokines, and alleviate alveolar inflammatory injury through anti-oxidation and anti-apoptotic processes. Human amniotic mesenchymal stem cells can also assist in the repair or homing to the damaged tissue to directionally differentiate to replace the apoptotic and necrotic cells. All of these characteristics of human amniotic mesenchymal stem cells provide new insight into the treatment of acute lung injury. As acute lung injury is caused by many pathogenic factors and its pathophysiological process is very complicated, human amniotic mesenchymal stem cell transplantation in the treatment of acute lung injury has many issues to be resolved.

Objective To investigate the association of estrogen receptor-? (ER-?) and vitamin D receptor (VDR) gene polymorphisms with peak bone mass in Shanghai women. Methods The ER-? PvuⅡ and XbaⅠ genotypes and VDR ApaⅠ genotypes were determined by PCR-RFLP in 515 unrelated healthy women aged 19-40 years of Han nationality in Shanghai. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry. Results Frequencies of ER-? PvuⅡ genotype PP, Pp and pp were 13.2%, 49.3% and 37.5% respectively. Frequencies of ER-? XbaⅠ genotype XX, Xx and xx were 4.7%, 40.4% and 54.9% respectively. Frequencies of VDR ApaⅠ genotype AA, Aa and aa were 5.8%, 41.9% and 52.3% respectively. Hardy-Weinberg equilibrium was evident for both ER-? and VDR gene polymorphisms. No association was found between ER-? PvuⅡ and XbaⅠ genotypes and BMD of various sites in women. Only a significant association was found between VDR ApaⅠ genotype and BMD at L 1-4(P

[摘 要] 目的:探讨敲减转录因子特异蛋白1(SP1)对小细胞肺癌(SCLC)H466/DDP细胞顺铂(DDP)耐药的影响及其分子机制。方法:构建敲减SP1同时过表达ATP结合盒亚家族C成员1(ABCC1)的SCLC H466/DDP细胞,采用IHC法检测SP1、ABCC1在非耐药和耐药SCLC组织中的表达,用Spearman r法分析SP1与ABCC1在SCLC组织中表达的相关性;WB法检测SP1、ABCC1、CD44在转染后H446/DDP细胞中的表达;CCK-8法、FCM术、微球实验检测转染后H446/DDP细胞的增殖、凋亡及自我复制能力的变化;染色质免疫共沉淀(CHIP)实验检测SP1是否是ABCC1的转录因子。结果:耐药细胞H446/DDP和耐药SCLC组织中的SP1、ABCC1蛋白水平均高于H446细胞和非耐药SCLC组织(均P<0.05),SCLC组织中的SP1、ABCC1蛋白表达呈正相关;敲减SP1抑制H446/DDP细胞的增殖活力,降低CD44、ABCC1蛋白表达水平、减少细胞微球形成数(均P<0.05),促进细胞凋亡(P<0.05);SP1是ABCC1的转录因子。结论:转录因子SP1通过调控ABBC1的表达影响SCLC H446/DDP细胞的耐药,SP1是SCLC对DDP耐药的潜在治疗靶点。
