ABSTRACT
Objective To explore the expression of the Merlin protein in normal cervix and cervical can-cer of the Han,Tibetan and Hui nationalities in Qinghai. Methods Immunohisto-chemical staining was per-formed to detect the expression of Merlin in 108 cases of cervical carcinoma(40 cases of Han,38 cases of Tibetan and 30 cases of Hui nationality)and 107 cases of normal cervix(40 cases of Han,37 cases of Tibetan and 30 cas-es of Hui nationality). Results The positive expression rates of Merlin in normal cervix were 90.0%,91.9%and 86.7%respectively and those in cervical carcinoma were 17.5%,18.4%and 16.7%respectively. There was signifi-cantly statistical difference(P0.05). The expression of Merlin was not correlated with age,FIGO stage,lymph metastasis and cell differentiation(P > 0.05)in cervical carcinoma of three ethnic groups. Conclusion The decrease or even deletion of Merlin may be involved in the development of cervical can-cer,and it plays an important role in cervical cancer. The expression of Merlin exerts no effect on the occurrence of cervical cancer and it is not associated with the clinical characteristics of the patients ,suggesting that it may not be involved in the invasion and metastasis of cervical cancer.
ABSTRACT
Objective To discuss the high-risk human papillomavirus (HPV )infection in the Guangxi .Methods A total of 26 796 copies of the test results for female cervical secretions specimens were analyzed retrospectively from what the second-genera-tion hybrid capture technology mixed detect 13 kinds of high-risk HPV viral DNA .Results Infection rate was 17 .94% in Guangxi , and the infection of HPV in north was higher than other regions ,and the differences of regions had statistically significant (P<0 .05) .The peak age of infection in the Guangxi region was less than 20 years old ,50- <60 years old ,and equal or more than 60 years old .The differences among age groups was statistically significant(P<0 .05) .Patients constitute HPV infection Guangxi re-gion had high viral load for 40 .93% ,and high viral load constituent ratio rise with age .Conclusion The existence of high-risk HPV infection is regional different and age different in the Guangxi region ,to high-prone areas ,infection high age should focus on monito-ring ,high viral load in patients with complete cervical cytology and histology examination if necessary .
