[Correlation of gastric cancer and effects of vitamin D receptor gene FokⅠ polymorphism on C-reactive protein and D-dimer in Uygur nationality patients].
OBJECTIVE
This study aimed to determine the correlation of Uygur gastric cancer and the polymorphism effects of vitamin D receptor gene FokⅠ on C-reactive protein and D-dimer.


METHODS
Method of random sampling was used to select 147 Uygur patients with gastric cancer who admitted at Tumor Hospital of Xinjing Medical University (Group A) and 151 healthy controls with the same nationality (Group B). Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used to determine FokⅠ loci polymorphism in both groups to identify the gastric cancer susceptibility gene. All patients were divided into Group FF (Group a) and Group Ff+ ff (Group b) by PCR-RFLP according to the f-gene carrier to compare the expression level of C-reactive protein and D-dimer.


RESULTS
The expression frequency of the f allelic gene of patients with gastric cancer was higher than that of healthy control patients (57.8% vs 47.4%, P<0.05). The carriers of the f allelic gene (Ff+ ff) had increased risk of gastric cancer (OR=2.85). Measurement levels of C-reactive protein and D-dimer in the f allelic gene group were higher than those of the non-f allelic gene group (4.72±1.65 vs 2.81±0.93, and 2.79±1.21 vs 1.09±0.65, respectively), and the differences were statistically significant (P<0.05).


CONCLUSIONS
The FokⅠ loci polymorphism of vitamin D receptor gene was related to gastric cancer susceptibility in Uygur. f allelic gene may be one of the risk factors of gastric cancer in Uygur. Moreover, f allelic gene may be a factor that increased the level of C-reactive protein and D-dimer in Uygur patients with gastric cancer.
