和谐边疆构建下的宗教渗透问题研究——基于对云南跨境民族的田野调查

通过对云南跨境民族地区的田野调查,该区域宗教渗透不仅没有停止,反而呈现出多样性、隐蔽性等特点。宗教渗透对跨境民族的国家政治认同等造成了严重破坏,对云南边疆社会的稳定构成了较大的威胁,成为了云南边疆地区非传统安全问题中最敏感、最复杂、最难解决的问题之一。抵御宗教渗透不仅要完善政府宗教管理能力、改善经济条件等,更要调动作为文化主体者的跨境民族自身的"文化自觉",以主动抵御宗教渗透。只有如此才是最有效的抵御宗教渗透举措,才最终有利于和谐边疆的构建。

Therapeutic applications of bone marrow-derived stem cells in liver transplantation for end-stage liver diseases

Today, liver transplantation (LT) is the only established treatment for end-stage liver diseases. The de- velopment of LT, including OLT, cadaveric LT, split LT, living donor LT (LDLT), brings hopes to patients with these diseases. However, increasing donor shortage, rejection and life-long immunosuppression with its side effects are the major limitations of this therapy strategy. Bone marrow-derived stem cells (BMDSCs) are capable of differentiating into hepatocyte-like cells and contribute to liver injury repair. The microenvironment of liver injury caused by rejection, ischemia/reperfusion, loss of liver mass, recurrence of HCV and "small-for-size syndrome" after LT can attract a variety of bone marrow-derived stem cell population to the peripheral circulation and then migration to the injury liver to promote the hepatic function restoration. Additionally, BMDSCs can also take part in the functional regeneration of living donor liver after LDLT. This participation in liver regeneration may be associated to the interac- tion between SDF-1and its receptor CXCR4, involving HGF, IL-8, MMP9, and VEGF/VEGFR-2. BMDSC with its bio-characteristics could maintain the allograft tolerance from different angles and in different ways. In conclusion, BMDSCs transplantation, as a new assistant therapeutic method for LT, will ex- pand the space of LT, and provide more survival opportunities for the patients suffering liver diseases in the future.
