Objective: To investigate the relationship between plasma EBV-DNA concentration and clinicopathologic features of Hodgkin's lymphoma cases. Methods: At first, the positive rate of plasma EBV-DNA was determined with a nested-PCR method using 45 specimens from Uygur HL patients, as well as 110 healthy people sampled as normal controls. Secondly, using fluorescent quantitative nested-PCR, EBV viral load was assessed in the EBV-DNA positive plasma samples. Then, relationships between plasma EBV viral load and clinicopathologic features of HL patients were analyzed. Results: The positive rate of plasma EBV-DNA of HL patients was significantly higher than that of normal controls (53.3% vs 26.4%, P=0.001). There was no significant difference about plasma EBV viral load between EBV-associated HL and EBV-DNA positive normal people (P=0.490). Looking at patients' characteristics, plasma EBV viral load in 10-20 years EBV-associated HL was higher than in EBV cases which were less than 10 years or more than 35 years (P=0.025). Furthermore, in EBV-associated HL, concentration of plasma EBV-DNA was significantly higher in advanced stage disease (stages III-IV; P=0.013), and with B-symptoms (P=0.020). Conclusion: EBV-DNA levels were associated with part of clinicopathologic features of cases. It was of practical use to screen HL. Further etiological studies appear warranted.

In this paper, polycaprolactone (PCL)/collagen (COL) nanofibrous membranes were prepared by electrospinning to study their mechanical properties as well as biocompatibility. The surface morphology was characterized by scanning electron microscopy (SEM) to access the effect of microstructure on the mechanical properties, cytocompatibility, and enzymatic degradation behaviors. In addition, the effect of hydrophilicity of membranes on the antithrombotic properties was also investigated. The results show that tensile strength of PCL/COL10 is higher than that of other samples due to smaller fiber diameters and tight spatial interlacing of PCL/COL10 membranes. In addition, the hydrophobic surface of PCL becomes hydrophilic after the addition of collagen, which affect platelet adhesion and cytocompatibility of nanofibrous membrane samples. The addition of collagen could promote the cell proliferation as well as the enzymatic degradation rate. Overall, PCL/COL10 has good morphology, the best mechanical properties, appropriate degradation rate, and the best antithrombotic effect as well as biocompatibility.
