Objective To study the angiogenesis in serous ovarian neoplasms. Methods Immunohistochemical method was used to examine microvessei density (MVD) and the expressions of vascular endothelial growth factor (VEGF) in 76 cases of serous ovarian neoplasm. The relationship between MVD and VEGF were investigated. Results MVD in the tissues of cystadenoma, bordline cystadenoma and cystadenocarcinoma were 7.8±2.4, 17.5±3.3 and 27.6±7.5; VEGF expressions were (16.1±3.9)%, (36.7±14.2)%, (52.3±22.8)%; the differences were significant respectively. Of cystadenocarcinoma grade 1, grade 2 and grade 3, MVD were 18.3+3.4, 24.2±3.1, and 32.3±6.4, VEGF expressions were (30.9±16.2)%, (48.0±18.4) % and (62.1±21.3) %, the differences were significant respectively. Of FIGO stage Ⅲ～Ⅳ and stage Ⅰ～Ⅱ, MVD were 28.9±4.7 and 22.0±4.7, VEGF expressions were (55.1±22.9) % and (40.18±18.0) %, the differences were significant respectively. There was significant positive correlation between VEGF expression and MVD. Conclusion Angiogenesis is very important in the development of serous ovarian neoplasms.

In spite of the relative success achieved in degree-oriented education program in clinical medicine during its preliminary trial stage, problems remain in regard to its recognition and understanding, administration policy, testing systems and the quality control. To further improve the Effects of the actual teaching, it is of high importance that we further our understanding, strengthen the administration, consolidate the testing system and implement better supervision of the teaching procedures of the program.

【Objective】 To investigate the molecular mechanism of long non-coding RNA (lncRNA) TDRG1 in facilitating the malignant progression and poor prognosis of patients with cervical cancer. 【Methods】 Cervical cancer cell lines and normal cervical cell Ect1/E6E7 were collected. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of TDRG1. Cervical cancer cell lines were transfected with TDRG1-siRNA, and the proliferation of cancer cells was detected by CCK-8 method and cell plate cloning experiment. The invasion and migration of cancer cells were measured by Transwell experiment. The apoptosis of cancer cells was examined by flow cytometry, and the expressions of relevant proteins were tested by Western blot. 【Results】 Compared with Ect1/E6E7, cervical cancer cell lines showed relatively increased expression of TDRG1. Downregulation of TDRG1 expression inhibited the proliferation and colony formation (162±21 vs. 411±33, P<0.05), as well as the invasion and migration (invasion: 86±13 vs. 315±38, P<0.01; migration: 177±22 vs. 406±41, P<0.01) of Hela cells. Meanwhile, the apoptosis of Hela cells increased [(28±1.5)% vs. (16±1.2)%, P<0.05] and the expression of Bcl-2 protein reduced. In addition, TDRG1 knockdown also decreased the activity of autophagy in Hela cells. 【Conclusion】 TDRG1 facilitates the malignant biological progression of cervical cancer by inhibiting the apoptosis and providing a protective autophagy in cervical cells.
