The present study was aimed to explore the relationship of transforming growth factor (TGF) beta3 gene SfaNI polymorphism (rs3917201 locus) and non-syndromic cleft lip with or without cleft palate (NSCL/P) in people of the Uygur's Nationality and Han's in Xinjiang, China. TGFbeta3 gene fragment including SfaNI was amplified and purified as the template of the primer extension reaction thenafter. The single base extension reaction was carried out u sing SNP specific extension primer. The products were purified and analyzed by MALDI-TOF. The test showed that there were not significantly different frequencies of AA, AG, GG genotypes and alleles between the whole NSCL/P group and the whole control group (P > 0.05). Within the Uygurs or Hans, the frequencies of genotypes between the whole NSCL/P group and the whole control group were not significantly different (P > 0.05). The distributions of the A, G alleles between the NSCL/P group and the control group were not significantly different within the Uygurs (P > 0.05), but significant different within the Hans (P < 0.05). In all the NSCL/P patients, frequencies of genotypes and alleles were not significantly different between Uygurs and Hans (P > 0.05), and not significantly different (P > 0.05) either between Uygurs and Hans in all the healthy persons. The results proved that TGFbeta3 gene SfaNI polymorphism may not be related to NSCL/P in Xinjiang Uygur people, while the occurrence of NSCL/P in Han population may be related to frequency of the A and G allele of SfaNI polymorphism.

Objective To develop an anatomically based method of accurate pedicle screw insertion for cervical spine fixation. Methods Forty adult cervical spine were mounted onto a specially designed jig. Parameters including height, width, length, and axis angulation of pedicles,depth of lateral fovea, height of superior posterior border of arcus vertebrae and angles of posterior articular prominance as well were mea sured with vernier calibre or goniometer either directly or radiographically. Results Lateral fovea did exist in all C2-C7 vertebrea. The pedicles of the cervical spine were wide and long enough to accept 28 mm long 3.5 mm screws. The abduction angle of the screw was 20? at the C1 level, 25? superiorly and 44? inferiorly at the C2 level, 45? to 47? from level C3 to C5, and 40? from level C6 to C7. The angle of posterior plane of articular mass was minus 2.30? at C3,it was 2.32? to 2.42? from level C4 to C6, and it was 15.22? at C7. The stability of cervical spine fixation and neurological improvement were satisfactory. Conclusion Transpedic ular screw fixation for the cervical spine is practicable. Anatomical symbol of the superior posterior border of the arcus vertebrae and the posterior plane of articular mass and the lateral fovea is easy to be exposed and identified in the operation. Transpedicular screw can be precisely inserted easily and safely for the cervical spine fixation with limited exposure and without using fluoroscopic guidance.
