ABSTRACT
Ovarian cancer ranks the third among gynecological malignancies, while its mortality rate is the highest. Even though recent treatment progress has been made after using PARP inhibitors, the prognosis is still poor. Anterior gradient protein 2 (AGR2) may be a marker for early diagnosis of ovarian cancer, and the expression of AGR2 suggests that the prognosis of ovarian cancer is better. However, Anterior gradient protein 3 (AGR3) could be used to differentiate high-grade and low-grade ovarian cancer, but its influence on prognosis is still controversial. AGR2 and AGR3 may be therapeutic targets for ovarian cancer. This article introduces the research progress of AGR2 and AGR3 in the diagnosis and treatment of ovarian cancer.
ABSTRACT
Ovarian cancer is the most fatal malignant tumor in female reproductive system tumors.In most women, it is diagnosed in a late stage, which largely leads to the poor prognosis of ovarian cancer.Breast cancer susceptibility gene (BRCA) is an important DNA homologous repair gene, which plays a major role in the normal cellular DNA repair mechanism.Its mutation will lead to homologous recombination defects, which will affect the stability of the genome and lead to occurrence of tumors.In recent years, BRCA genetic testing has become a key step in the risk assessment, prognosis, treatment and prevention of ovarian cancer.
ABSTRACT
Objective To detect the expression of insulin-like growth factor Ⅱ mRNA-binding protein 3 (IMP3) and p16 in cervical carcinoma and investigate their clinical significance.Methods Immunohistochemical Envision method was used to detect the expression of IMP3 and p16 proteins in 67 cases of carcinoma of the uterine cervix,58 cases of cervical intraepithelial neoplasia (CIN) and 15 cases of normal cervical epithelium.Results IMP3 was mainly dedected in the cytoplasm,whose positive expression rate was 85.07％ (57/67) in cervical carcinoma,12.07％ (7/58) in CIN (x2 =66.32,P ＜ 0.05) and 0 (0/15) in cervical epithelium (x2 =44.38,P ＜ 0.05).No significance variations of the expression of IMP3 were observed in cervical adenocarcinoma and squamous cell carcinoma (x2 =0.35,P ＞ 0.05).p16 was found both in nucleus and cytoplasm of cervical carcinoma,whose expression rate was 83.58％ (56/67),higher than 41.37％ (24/58) in CIN (x2 =24.85,P ＜ 0.05) and 0 (0/15) in cervical epithelium (x2 =42.61,P ＜ 0.05).Conclusion Expression of IMP3 and p16 is high in cervical carcinoma,maybe can be used as a potential biomarker of metastasis and progression.
ABSTRACT
OBJECTIVE:To provide information about the current situations and trend of development in Chinese phar?maceutical trade.METHODS:We have generally overviewed the basic situation and existing problems in Chinese pharmaceu?tical trade and analysed and discussed its trend of development in the future.RESULTS&CONCLUSION:Chinese pharma?ceutical enterprises must think highly of their existing problems and the chances and challenges after entry into WTO,and take corresponding countermeasures to continually strengthen and improve their power of competition and jointly keep Chinese pharmaceutical trade healthy,constant and stable development.
