Pulsed electromagnetic fields stimulate osteogenic differentiation and maturation of osteoblasts by upregulating the expression of BMPRII localized at the base of primary cilium

Pulsed electromagnetic fields (PEMFs) have been considered as a potential candidate for the prevention and treatment of osteoporosis, however, the mechanism of its action is still elusive. We have previously reported that 50 Hz 0.6 mT PEMFs stimulate osteoblastic differentiation and mineralization in a primary cilium- dependent manner, but did not know the reason. In the current study, we found that the PEMFs promoted osteogenic differentiation and maturation of rat calvarial osteoblasts (ROBs) by activating bone morphogenetic protein BMP-Smad1/5/8 signaling on the condition that primary cilia were normal. Further studies revealed that BMPRII, the primary binding receptor of BMP ligand, was readily and strongly upregulated by PEMF treatment and localized at the bases of primary cilia. Abrogation of primary cilia with small interfering RNA sequence targeting IFT88 abolished the PEMF-induced upregulation of BMPRII and its ciliary localization. Knockdown of BMPRII expression level with RNA interference had no effects on primary cilia but significantly decreased the promoting effect of PEMFs on osteoblastic differentiation and maturation. These results indicated that PEMFs stimulate osteogenic differentiation and maturation of osteoblast by primary cilium-mediated upregulation of BMPRII expression and subsequently activation of BMP-Smad1/5/8 signaling, and that BMPRII is the key component linking primary cilium and BMP-Smad1/5/8 pathway. This study has thus revealed the molecular mechanism for the osteogenic effect of PEMFs.     

老年中晚期原发性肝癌患者生活质量及其对生存期的影响

目的:观察老年中晚期原发性肝癌患者的生活质量状况及其对生存期的影响。方法:回顾性分析2014年01月至2016年12月我院收治的115例老年原发性肝癌患者，调查他们的生活质量指数（LQI），比较不同LQI水平原发性肝癌患者的生存情况，并分析影响预后的危险因素。结果:本组患者生活质量的总分是（118.72±34.26）分，LQI是0.59±0.13。参照患者1年生存状态，LQI的最佳临界值为0.63，曲线下面积为0.696。高LQI组的中位生存时间为16.5个月，显著高于低LQI组的12.4个月(P=0.037）。与低水平LQI组比较，高水平LQI组的年龄、谷丙转氨酶（ALT）、谷草转氨酶（AST）、凝血酶原时间（PT）、总胆红素（TBIL）和甲胎蛋白（AFP）水平以及门静脉癌栓发生率、保守治疗率更小或更低，白蛋白（ALB）水平和BCLC分期更高，差异均有统计学意义（P<0.05）。单因素分析结果显示，老年中晚期原发性肝癌的预后与ALB、AFP、Child-Pugh分级、门静脉癌栓、肝外转移、BCLC分期、药物保守治疗和LQI相关（P<0.05）。多因素分析结果显示，AFP≥400 ng/ml、BCLC C期和药物保守治疗是预后的独立危险因素（P<0.05），而非门静脉癌栓、非肝外转移、LQI≥0.63是其独立保护因素（P<0.05）。结论:老年中晚期原发性肝癌患者生活质量较低，生活质量越低，预后越差。     

唐山地区3家医院脑梗死二级预防中叶酸的应用现况调查

目的:了解唐山市部分医院脑梗死二级预防中叶酸的应用现状,找到与相关指南之间的差距,为改进脑梗死二级预防工作提供参考。方法:研究对象为唐山市3家医院诊断为脑梗死的住院患者共573例,按照血浆总同型半胱氨酸(tHcy)水平将入选病例分为3组,调查不同组别患者二级预防中叶酸的应用现状。结果:叶酸的使用率在血浆tHcy重度升高组为62.9%,在中度升高组中为50.7%,在轻度升高组中为38.1%,3组间比较差异有统计学意义(P<0.05);但叶酸的使用量3组间比较差异无统计学意义(P>0.05)。结论:唐山地区部分医院对叶酸应用于脑梗死二级预防已经有了一定程度的认识,但使用率、使用量等与相关指南尚有距离,需进一步加强对医务人员的培训。     

HLA-G在胃癌患者外周血及癌组织中的表达与临床意义

目的:探讨HLA -G在胃癌中表达的临床意义.方法:采用流式细胞仪测定经病理组织学确诊为胃癌患者的癌组织、正常胃黏膜及外周血单个核细胞中HLA -G的表达水平.结果:在正常胃黏膜及外周血单个核细胞中的表达较低,而在胃癌组织中呈高表达,胃癌组织与正常胃黏膜、外周血单个核细胞两组间表达差异有统计学意义(P＜0.05).正常胃黏膜组与外周血组相比差异无统计学意义(P＞0.05).随着胃癌组织分化程度的降低、TNM分期的增高及出现淋巴结转移,胃癌组织中HLA-G的表达量显著升高(P＜0.05).结论:胃癌组织中HLA -G的高表达可能参与了胃癌局部的免疫逃逸,有利于胃癌的发生和进展.
