Objective:To explore the mechanism of Golgi phosphoprotein 3 (GOLPH3) regulating the proliferation and apoptosis of endometrial cancer (EC) cells through PI3K/AKT/GSK3β signal.Methods:Human endometrial adenocarcinoma HEC-1-B cells were divided into control group, GOLPH3 group and GOLPH3 + GDC-0941 group. GOLPH3 was over-expressed by transfection of the GOLPH3 pcDNA. The PI3K inhibitor GDC-0941 was used to block the PI3K/AKT/GSK3β pathway. Cell viability, cell proliferation and apoptosis were measured by CCK-8 method, clone formation experiment and flow cytometry, respectively. The protein phosphorylation level in PI3K/AKT/GSK3β pathway was detected by Western blotting.Results:Transfection experiments were successful, and the PI3K inhibitor GDC-0941 did not affect GOLPH3 mRNA and protein expression. The relative cell viability of the control group, the GOLPH3 group and the GOLPH3 + GDC-0941 group were (100.00±4.63)%, (131.56±7.85)% and (97.85±7.36)%, and the difference among the three groups were significant ( F=7.437, P<0.001). The cell viability of the GOLPH3 group was higher than that of the control group ( P<0.001). The cell viability of the GOLPH3 + GDC-0941 group was lower than that of the GOLPH3 group ( P<0.001). The numbers of cell clones in the three groups were 46.86±3.56, 89.32±4.78 and 46.48±4.05, and the difference was significant ( F=20.437, P<0.001). GOLPH3 group had more clones than control group ( P<0.001). The number of clones formed in the GOLPH3 + GDC-0941 group was less than that in the GOLPH3 group ( P<0.001). The apoptosis rates of the three groups were (5.17±0.61)%, (2.34±0.56)% and (6.85±0.53)%, and the difference was significant ( F=11.643, P<0.001). The apoptosis rate of the GOLPH3 group was lower than that of the control group ( P<0.001), and the apoptosis rate of the GOLPH3 + GDC-0941 group was higher than that of the GOLPH3 group ( P<0.001). The phosphorylated PI3K/PI3K levels of the three groups were 1.00±0.09, 3.32±0.19 and 0.93±0.06, respectively; phosphorylated AKT/AKT levels were 1.00±0.11, 4.63±0.63 and 1.15±0.16, respectively; phosphorylated GSK3β/GSK3β levels were 1.00±0.08, 4.06±0.57 and 1.04±0.14, respectively. The differences were statistically significant ( F=12.532, P<0.001; F=16.792, P<0.001; F=15.311, P<0.001). The phosphorylation levels of each protein in the GOLPH3 group were higher than those in the control group (all P<0.001), and the GOLPH3 + GDC-0941 group were lower than the GOLPH3 group (all P<0.001). Conclusion:In EC cells, over-expression of GOLPH3 can promote cell proliferation and inhibit apoptosis by activating the PI3K/AKT/GSK3β pathway, suggesting that GOLPH3 is involved in the occurrence and development of EC.

Objective To investigate bacterial vaginosis (BV)and vulvovaginal candidiasis (VVC)in women and to analyze its related factors.Methods The conditions of Physical examina-tion of 1967 female patients in the region from 2011 to 2013 were analyzed,and questionnaire was used to explore the relevant factors that affect the occurrence of BV and VVC.Results There were 282 patients with vulvovaginal yeast disease with the detection rate of 14.34%(282 /1967);231 patients were detected with bacterial vaginosis with 11.74% of detection rate (231 /1967);The higher detection rate of vulvovaginal candidiasis occurred among 25 to 35 year old and there was no significant difference in the occurrence of BV (P >0.05);Logistic analysis revealed that abortion was the risk factors that affect the treatment of VVC and BV;The man cooperated with the treatment and used condoms as protective factor as the safe factor.Conclusion VVC and BV are associated with vaginal microflora imbalance,so the patients should pay attention to healthy hy-giene habits as well as focus on treatment of the partners to block cross-infection and ensure good treatment effect.
