BACKGROUND:In recent years, interventional therapy because of its high success rate, good curative effect, little trauma has been widely recognized, but vascular intimal injury due to interventional therapy stil has no effective treatment, resulting in long-term postoperative severe restenosis. Stem cel transplantation has brought a new drawn for the repair of impaired endothelial function, reendothelialization and aided restoration of the blood supply to ischemic tissues. OBJECTIVE: To summarize the recent progress in umbilical cord blood stem cels transplantation and endovascular treatment for treatment of diabetic lower limb ischemic disease. METHODS: A computer-based search of PubMed and CNKI was performed for relevant articles published from January 2000 to March 2015 using the keywords of “umbilical cord blood stem cel transplantation, percutaneous transluminal angioplasty, diabetic lower limb ischemia, restenosis” in English and Chinese. Totaly 216 relevant literatures were initialy obtained, and 44 articles were ultimately included. RESULTS AND CONCLUSION:By comparing the therapeutic efficacy and long-term prognosis of umbilical cord blood stem cel transplantation and endovascular treatment, it is concluded that umbilical cord blood stem cel transplantation combined with endovascular treatment is better than either of them alone, which can promote the establishment of colateral circulation, improve the impaired endothelial function and reduce the occurrence of restenosis after interventional therapy.

Objective:Reporting a rare case with Kimura's disease and angiolymphoid hyperplasia with eosinophilia (ALHE), who also has nephrotic syndrome resulting from minimal change glomerulopathy. Methods: Histological manifestations, immunohistochemical staining, immunofluorescence staining, and electron microscope were performed. Results: One 37-year-old male patient with recurrent erythra, cutaneous node, painless cervical lymph node enlargement and nephrotic syndrome in 5 years. It's confirmed through biopsies that the subcutaneous node is ALHE, the cervical lymph node is kimura disease, and renal lesion is minimal change glomerulopathy. Conclusion: Kimura disease and ALHE may be different features of the same disease, and may complicate glomerulopathy.

Extracellular adenosine triphosphate (ATP) and adenosine are important signaling molecules in both intracellular and extracellular microenviroments of cells. They exert cytoxic and apoptotic effects in some tissues such as tumor. The proapoptotic mechanisms of adenosine and its receptors are involved in Adenylyl cyclase(AC), cAMP, Ca 2+ , etc. Apoptosis induced by ATP is as sociated with several purinergic receptors including P2X_1, P2X_2, P2X_7, P2Y_1, P2Y_2, et al, it is also involved in FasL/FasR, T cell receptor(TCR), and gene regulations of bcl-2 and bax.

Objective:To explore the placental expression of farnesoid X receptor( FXR) ,as well as the total bile acid (TBA) levels in maternal and umbilical cord serum in intrahepatic cholestasis of pregnancy (ICP) and normal late pregnancy. To evaluate the roles of placental FXR in the pathological mechanism of ICP. Methods:Maternal and umbilical cord blood as well as placentas were collected in gravidas of 33 ICP (ICP group) and 33 normal late pregnancy (control group). According to maternal serum TBA levels, ICP group was divided into mild and severe subgroup, the latter with TBA ≥40 μmol/L TBA levels were measured by velocimetry and the placental FXR mRNA expression were examined by real time nested RT-PCR. Results:①Comparing the rate of meconium -stain of amniotic fluid: The rate in ICP group was significantly higher than that in control group(χ~2=7.543,P=0.013); The rate in serve ICP group was significantly higher than that in mild ICP group(χ~2= 7.637,P=0.013). ②The expression of FXR mRNA in placentas: placental FXR mRNA expression was significantly higher in ICP group than that in control group (z = -2. 391, P = 0.017). Placental FXR mRNA expression was higher in severe ICP group than that in mild ICP group (z= -2.391 ,P=0.017).③ln ICP group, a positive correlation was found between the placental FXR mRNA expression and the maternal serum TBA levels as well as umbilical serum TBA levels(r_s =0.348,P=0.047; r_s =0.284,P=0.027). There were no significant correlations between maternal serum as well as umbilical serum TBA levels and placental FXR mRNA expression in control group ( r_s = - 0.068, P = 0.716; r_s = 0.010,P=0.959). Conclusions:Placental FXR mRNA expression is up regulated by increased bile acid levels in ICP, which may represent a compensatory (anti-cholestatic) mechanism of placenta in ICP.
