Abstract:
Objective To observe the expression levels of PI3K ,ERK ,IGF‐1R and ER in cervicitis and cervical squamous cancer tissues among Uighur and Han ethnic patients and their correlation .Methods The 90 paraffin embedding samples of cervici‐tis tissue( 46 cases for Han and 44 cases for Uighur) and 224 paraffin embedding samples of cervical squamous cancer tissue (36 ca‐ses for Han and 188 cases for Uighur) were collected and detected the protein expression levels by using immunohistochemistry .Re‐sults The positive expression rates of IGF‐1R and PI3K in cervical squamous cancer were 58 .04% and 92 .41% respectively ,which were higher than 13 .33% and 57 .78% in cervicitis tissue ,the positive expression rates of ER and ERK in cervical squamous cancer were 22 .32% and 68 .30% respectively ,which were lower than 63 .33% and 95 .56% in cervicitis tissue ;the positive expression rate of IGF‐1R and PI3K of cervical squamous cancer in Han and Uighur were 69 .44% ,88 .89% and 55 .85% ,93 .09% respective‐ly ,which were higher than 15 .22% ,54 .35% and 11 .36% ,61 .36% of cervicitis tissue ;the positive expression rate of ER and ERK of cervical squamous cancer in Han and Uighur were 13 .89% ,83 .33% and 23 .94% ,65 .43% respectively ,which were lower than 65 .22% ,93 .48% and 61 .36% ,97 .73% of cervicitis tissue respectively ;the expression of ERK in Uighur cervical squamous carci‐noma tissue was 65 .43% ,which was lower than 83 .33% in Han ,the difference was statistically significant (P<0 .01) .Conclusion PI3K ,ERK ,IGF‐1R and ER protein expression positive or deficiency is closely related to the occurrence of cervical cancer ,which may serve as the important biological indicators for detecting cervical cancer ,and the ethnic difference of ERK protein expression exists in cervical cancer .
