Objective To define a parameter of autologous arteriovenous fistula stenosis that limits the fistula function for hemodialysis in our country.Methods Retrospectively study the doppler ultrasound of patients who accepted the percutaneous transluminal angioplasty (PTA) therapy due to autogenous arteriovenous fistula dysfunction;identify the least diameter of the fistula vein and compare it with the corresponding data of well-functioned fistula.Determine which absolute diameter constitutes a hemodynamically significant stenosis in a radioeephalic autologous arteriovenous fistula by receiver operating characteristic curve (ROC curve).Result Forty-two patients were enrolled in the study.The average age of those patients was 54.63±2.44 years old.Twenty-one patients were female.Twenty-six fistula located on the left arm.The minimal diameter of the dysfunction fistula averaged 1.57±0.07 mm,while the average forearm fistula vein diameter was 4.04±0.23 mm,significantly smaller than those in the compare group-an average minimal fistula vein diameter of 3.34±0.11 mm and a forearm vein diameter of 5.36(4.52,6.45) mm (P ＜ 0.05).The control group contained sixty-eight patients.The average age of those patients was 52.56±2.00 years old.Thirty-one patients were female.Forty-nine fistula located on the left arm.It was quiet appropriate in using minimal diameter of the fistula vein to indicate the dysfunction istula with an under-curve area of 0.979,95％C1 0.959-0.998.The under-curve area would be at the largest level when meeting the cutoff point at 2.40mm,in which it could achieve the area of 0.853.Conclusions The minimal diameter of the dysfunction wrist autogenous arteriovenous fistula was much smaller than the functioned ones.Minimal diameter of the fistula vein may serve as an effective parameter in detecting dysfunction fistula.

BACKGROUND:Uric acid as an endogenous antioxidant has garnered increasing attentions because of its anti-oxidation, anti-DNA damage and neuroprotective effects.
OBJECTIVE:To observe the effect of uric acid at different concentrations on the neural differentiation of bone marrow mesenchymal stem cells.
METHODS:Bone marrow mesenchymal stem cells were isolated, purified and cultured in vitro. The morphology change was observed. The third passages of bone marrow mesenchymal stem cells were induced to differentiate to neuron-like cells by induced liquid containing four different concentrations of uric acid (0 mmol/L as control group, 0.2 mmol/L, 0.4 mmol/L, 0.8 mmol/L) for 24 hours. Then, after second intervention for 1 hour, cells were detected by Nissl staining and specific markers were detected by immunohistochemistry method.
RESULTS AND CONCLUSION:After induction, the cellbody shrank, forming processes and connections. Nissl body was found in the cytoplasm. The positive rates of neuron-specific enolase were significantly higher in uric acid groups of different concentrations compared to the control group (P<0.05);moreover, the positive rates of neuron-specific enolase were increased as the increase in concentrations of uric acid (P<0.05). The positive rates of Nestin were decreased in uric acid groups of different concentrations compared to the control group (P<0.05). After 4 hours of induction, cells fel off significantly. In a certain period of time, uric acid can promote differentiation of bone marrow mesenchymal stem cells into neuron-like cells in a certain concentration-dependent manner in vitro.
