Methods: The clinical information of 275 patients with cervical cancer were retrospectively analyzed between 2006 and 2011, including the patients' age, clinical FIGO stage, differentiation, histologic grade, infiltration depth, treatment, pathological diagnosis after surgery, and results of following-up.Immunohistochemistry was also done on sections of confirmed cancer specimens without prior chemotherapy/radiotherapy. Results: Among various clinicopathological parameters, the median age was 48 years old. The grade was significantly associated with histological type, HPV infection and with lymph node invasion. FIGO stage was strongly correlated to the infiltration depth and lymph node metastasis. P16INK4A expression was significantly correlated with histologic grade. However, there were no differences between p16INK4A staining and patient's age, histopathology and lymph node metastases. Conclusion: The incidence of cervical cancer becomes increasingly younger. Additionally, p16INK4A can function as a diagnostic marker of cervical carcinomas.展开更多

Methods: The mononuclear cells were separated from the peripheral, spleen and uterus or placenta blood. Flow cytometry was employed to analyze the percent of Treg cells in total T cells in different stages of pregnancy. Immunohistochemical staining was used to make sure the distribution of Treg in spleen in different stages of pregnancy. Results: The results of immunohistochemical staining showed that compared with spleen Treg cells in normal unpregnant mice, spleen Treg cells on day 7 and 14 of pregnancy significantly increased. After splenectomy, peripheral blood and placenta Treg cells on day 7 of pregnancy markedly decreased as compared with the normal pregnancy(P<0.01). And the cells on day 14of pregnancy were markedly recovered as compared with the normal pregnancy. Conclusion: Our study indicated that the spleen and its Treg cells might play important roles in transient tolerance during pregnancy.展开更多
