Objective To implore FHIT expression in the tissue of cervical carcinoma and its clinical significance. Methods To determine the FHIT expression in 42 cases of cervical carcinoma by S2P immunohistochemical staining and to make a comparison with the normal one. Results The FHIT expression in normal tissue showed to be normal or even positive. No descending or short one occurred. The expression in cervical carcinoma was significantly low or short, abnormal one reached 57.14 %. The descending and short expression had something to do with histological type and grade (P 0.05). Conclusions The ascending or descending of FHIT expression plays an important role, which might influence the prognosis of cervical carcinoma.

Objective To characterize the C677T polymorphism of 5,10-methylenetetrahydrofolate reductase (MTHFR) gene in Xinjiang Uygur and Han nationality population.Methods The C677T polymorphism of MTHFR gene was detected by using PCR-restriction fragment length polymorphism (RFLP) in 134 Uygur and 166 Han nationality people.Results There were 3 MTHFR C677T genotypes,i.e.,CC,CT,and TT.A significant difference was observed in the frequency of CC,CT,and TT genotypes of MTHFR C677T polymorphism between Han and Uygur nationality people (21.7％,53.0％ and 25.3％ vs.16.4％,80.6％ and 2.96％,x2 =33.78,P ＜ 0.01).The frequency of CC,CT,and TT genotypes of MTHFR C677T polymorphism was 16.95％,79.67％,3.39％ respectively,in men of Uygur nationality,16.0％,81.33％,2.67％ respectively,in women of of Uygur nationality,25.8％,47.1％ and 27.1％ respectively in men of Han nationality,17.28％,59.26％ and 23.46％ respectively in women of Han nationality.There was no gender difference in the distribution of MTHFR C677T polymorphism in Han or Uygur nationality population (both P ＜ 0.05).Conclusions There is a significant difference between Uygur and Han nationality population,but no gender difference is observed,in the distribution of MTHFR C677T genotypes in Xinjiang Uygur Autonomous Region.
