[Distribution of HLA-DRB1 allele polymorphism in the Uyghur women with family history of cervical cancer].

OBJECTIVE: To study the distribution of HLA-DRB1 allele polymorphism in Uyghur women with family history of cervical cancer, and provide theoretical evidence for detection and follow-up of high risk persons for cervical cancer by detection of HLA-DRB1 allele polymorphism. METHODS: The HLA-DRB1 13 alleles were detected in 1000 Uyghur women, all from Hotan Moyu county Karsay village by using polymerase chain reaction sequence-specific oligonucleotide (PCR-SSO) assay. RESULTS: The frequencies of HLA-DRB1*15 in women with family history of cervical cancer (17.3%), mother (18.0%) and other relatives except mother (17.0%) who had suffered from cervical cancer were significantly higher than that in the control group (9.7%, all P < 0.05). The frequencies of HLA-DRB1*04 in women with family history (16.8%) and other relatives except mother (20.7%) were significantly higher than that in the control group (12.7%, all P < 0.05). The frequencies of HLA-DRB1*03 in women with family history (2.6%) and other relatives except mother (1.1%) were significantly lower than that in the control group (6.3%, all P < 0.01). The frequencies of HLA-DRB1*12 in women with family history of cervical cancer (2.3%) and mother suffered from cervical cancer (1.5%) were significantly lower than that in the control group (5.7%, all P < 0.05). The frequencies of HLA-DRB1*14 in women with family history of cervical cancer (5.4%) and mother who suffered from cervical cancer (3.0%) were significantly lower than that in the control group (8.4%, all P < 0.05). CONCLUSIONS: There are similarity and difference in distribution of HLA-DRB1 allele polymorphisms between the Uyghur women with family history of cervical cancer from Hotan Moyu county and those from southern Xingjiang area. In general, the distribution of HLA-DRB1 allele polymorphism in women with family history of cervical cancer is similar to that reported in abroad. The results of this study support the role of susceptible and protective HLA gene detection in screening high risk persons for this cancer among Uyghur women from cervical cancer high risk areas in Xinjiang.

[The effect of total phenolics from abnormal savda munziq on cervical cancer cell lines].

OBJECTIVE: To explore the feasibility of total phenolics from Abnormal Savda Munziq on treating human cervical carcinoma. METHODS: MTT assay was used to determine the growth inhibition ratio and IC50 on Hela cells and SiHa cells after treated with different concentrations of total phenolics. Morphologic changes of cells were observed by inverted microscope. RESULTS: Total phenolics inhibited the proliferation of Hela cells in the concentration range of 25 - 125 microg/mL; Total phenolics inhibited the proliferation of SiHa cells in the concentration range of 75 - 175 microg/mL; The inhibitory actions of total phenolics on the Hela and SiHa appeard dose-effect relationship and time-effect relationship obviously (P < 0.01); The IC50 of Hela was (125.26 +/- 16.15) microg/mL after 48h total phenolics treatment; The IC50 of SiHa was (134.51 +/- 2.55) microg/mL after 48h total phenolics treatment. And there was no statistical sense in the disparation of them (P > 0.05); Both of the cells showed apoptosis character evidently after total phenolics treatment, Along with the increasing of the concentration and the action time, morphologic changes of cells were more obviously. CONCLUSION: Total phenolics could inhibit the growth of Hela cells and SiHa cells and the inhibitory actions of total phenolics on the two cells is almostly the same. Therefore, total phenolics from abnormal savda munziq is deserved to be further studied for treating human cervical carcinoma.
