Abstract
Objective: To compare the long-term clinical effect and imaging results of Bryan artificial cervical disc replacement (ACDR) and anterior cervical discectomy and fusion (ACDF) and to explore whether ACDR can reduce the occurrence of postoperative adjacent segment degeneration (ASD) in the treatment of degenerative cervical spondylosis. Methods: It was a retrospective study. Total of 60 patients with degenerative cervical spondylosis, who had received operations by Bryan ACDR (n=27) and ACDF (n=33) in the Third Hospital of Hebei Medical University between January 2005 and December 2009 were enrolled in this study. The Japanese Orthopedic Association (JOA) scores, neck disability index (NDI), visual analogue scale (VAS), Odom's scale, cervical range of motion (ROM), surgical segment ROM, heterotopic ossification (HO) and ASD were used to evaluate the clinical and radiologic results. The indices abovementioned were compared between the two groups. Results: The VAS, NDI and JOA scores at each follow-up node in both ACDR and ACDF group were all significantly improved when compared with those before operation (all P<0.05), but there was no significant differences between the two groups (all P>0.05). Of all, 88.9%(24/27) of patients in ACDR group and 84.8%(28/33) of patients in ACDF group achieved excellent or good results, however, there was no significant difference in Odom's scale between the two groups (P>0.05). At the last follow-up, the cervical ROM in ACDR group was 43.2°±8.8°, which was slightly lower than that before operation (45.7°±10.4°), the difference was not statistically significant (t=0.954, P=0.345); the surgical segment ROM in ACDR group was 5.9°±3.6°, which was significantly reduced when compared with that before operation (8.8°±3.4°, t=3.043, P<0.01). However at the last follow-up, the cervical ROM in ACDF group was 36.4°±8.4°, which was significantly reduced when compared with that before operation (43.9°±11.1°), the difference was statistically significant (t=3.095, P<0.01). Although, there was no significant difference in the cervical ROM between the two groups before operation (t=0.643, P=0.523), and the difference was statistically significant at the last follow-up (t=3.054, P<0.01). At the last follow-up, the incidence of HO in ACDR group was 92.6%, and the high-grade HO was 37.0%. The incidence of ASD in ACDR group was 39.5%, which was much lower than that in ACDF group (61.1%, χ(2)=4.462, P=0.035). Conclusion: At minimum follow-up of 10 years, Bryan ACDR achieves a satisfactory clinical effect consistent with ACDF. In terms of advantages, ACDR could maintain the ROM of cervical and retain the ROM of the surgical segment, which reduces the occurrence of ASD by preserving motion.

Abstract
This paper reports the study of the effect of ginsenopolypeptide on 3H-TdR integration in normal human blood lymphocytes in vitro with micro-blood culture method of 3H-TdR integration. The results showed that the effect of ginsenopolypeptide on 3H-TdR integration in normal human peripheral blood lymphocytes which can be activated by phytoagglutinin was enhanced at low dosage and inhibited at high dosage, and its stimulating spike was 10(-6) micrograms/ml (P less than 0.01).
