Objective To explore the role of forkhead box protein O3a (FOXO3a) in inhibiting the proliferation and metastasis of breast cancer cells by downregulation of vascular endothelial growth factorA (VEGF-A).Methods Cell proliferation bioassay and plate clone formation assay were used to compare the changes of proliferation after siRNA interference.Wound healing and Transwell were used to compare the changes of invasion metastasis after interference.Meanwhile,the changes of VEGF-A expression in the cells before and after interference were compared by real time polymerase chain reaction (RT-PCR) and Western blot.Furthermore,the expressions of mRNA FOXO3a and VEGF-A were detected in 20 cases of breast cancer patients in breast cancer tissues and adjacent normal breast tissues.Results The MCF-7 and MDA-MB-231 cells were increased in cell proliferation and invasion after interference.Further studies found that mRNA and protein expression of VEGF-A were up-regulated in MCF-7 and MDA-MB-231cells after interference.In vivo the expression of FOXO3a was lower in 15 cases of cancer compared to normal tissues,and the expression of VEGF-A was high in 15 cases of cancer (75％).FOXO3a and VEGF-A expression was highly negatively correlated.Conclusions This study showed that FOXO3a could inhibit the proliferation and invasion of breast cancer cells,which might be regulated by VEGF-A.It provides an important theoretical evidence for targeted inhibition of breast cancer metastasis.

Objective To study the effect of the uncertain deflection of the Delta4 phantom (ScandiDos AB,Sweden) in setting up on the Gamma index passing rate during the VMAT plan verification.Methods Two patients with head and neck cancer,two with lung cancers and one with pelvic cancer receiving VMAT radiotherapy were randomly chosen.By means of Eclipse8.6 TPS the treatment plans elaborated for the five patients were picked up to make the verification plans and Delta4 was used to perform dose verification On VARIAN Clinac Ⅸ.The Delta4 phantom was precisely set up first,and then it was deflected in a given angle towards the horizontal direction in relation to the center of the linear accelerator isocenter to perform the dose verification for 11 times successively.To figure out the relationship between the deflection angle of the Delta4 phantom and the Gamma index passing rate.Results As the Delta4 phantom was deflected by 0.0°,0.2°,0.4°,0.6°,0.8°,1.0°,1.2°,1.4°,1.6°,1.8° and 2.0° in sequence,the measured Gamma index passing rates presented a slight decline,but all greater than 90％ (DD 3％,DTA 3 mm).Conclusions In the VMAT plan verification,the Gamma index passing rate of Delta4 has no dependence on the uncertain deflection of the Delta4 phantom provided that the uncertain deflection of the Delta4 phantom is no greater than 2°,but the passing rates of DD and DTA vary significantly with the uncertain deflection of the Delta4 phantom.

AIM:To investigate peripapillary vessel density and its relationship with other ocular parameters in highly myopic eyes with peripapillary intrachoroidal cavitation (PICC), and to analyze risk factors for PICC.METHODS:Cross-sectional study.A total of 35 highly myopic eyes with PICC, 40 highly myopic eyes without PICC and 35 normal eyes were included in this study.All participants underwent fundus photography and spectral-domain optical coherence tomography (SD-OCT).OCT angiography was also performed to image the retinal vasculature in the peripapillary areas of different sectors, including the radial peripapillary capillaries (RPC) and optic nerve head (ONH) layer.The difference of morphology changes in optic disc and peripapillary vessel density between these three groups were compared.Correlations between peripapillary vessel density and PICC and risk factors for the presence of PICC were analyzed.RESULTS: Significant differences were found among the three groups in spherical equivalent refraction (SER), best-corrected visual acuity (BCVA), axial length, peripapillary atrophy β-zone (β-PPA) area, retinal nerve fiber layer (RNFL) thickness and the presence of tilted optic disc, posterior staphyloma and myopic maculopathy (MMD) (P<0.05).There were significant differences among the three groups in the peripapillary vessel density both in RPC (54.34±5.58, 57.54±7.44, 64.42±3.50) and ONH (51.24±7.43, 52.75±9.96, 61.25±4.15) layers (P<0.001).In highly myopic eyes, vessel density was significantly lower in eyes with PICC than in those without in inferotemporal area both in the RPC (56.76±6.62,63.84±6.02,67.52±4.78) and ONH (56.47±5.79,60.38±4.72,64.18±4.37) layers.The vessel density was significantly correlated with the presence of MMD, β-PPA area and RNFL thickness in the RPC layer, whereas correlated with the presence of MMD, PICC and RNFL thickness in the ONH layer (P<0.05).Tilted optic disc and posterior staphyloma were independent risk factors for the presence of PICC (OR=8.007, 95%CI: 2.045-31.348;OR=7.558, 95%CI: 1.398-50.026).CONCLUSION:Highly myopic eyes with PICC had relatively lower peripapillary vessel densities, especially in the temporal area, than those without.Tilted optic disc and posterior staphyloma were independent risk factors for the presence of PICC.

OBJECTIVETo observe the effect of Zhibai Dihuang Decoction (ZDD) on mRNA and protein expressions of transient receptor potential family vanilloid subtype 1 (TRPV1) and transient receptor potential family vanilloid subtype 5 (TRPV5) in Ureaplasma urealyticum (UU)-infected rat semens and spermatogenic cells, and to explore the pathomechanism of UU-infected infertility and the intervention of ZDD.

METHODSTotally 45 were randomly selected from 60 4-5 months old SD rats. UU testicular infected animal models were set up after bladder inoculation of UU suspension. The remaining 15 rats were simultaneously injected with normal saline as a normal control group. After a successful modeling, UU infected model rats were randomly divided into the model group, the azithromycin group, and the ZDD group, 15 in each group. Rats in the ZDD group were administered with ZDD at the daily dose of 1 g/kg by gastrogavage. Rats in the azithromycin group were administered with azithromycin suspension at the daily dose of 0. 105 mg/kg by gastrogavage. Equal volume of normal saline was administered to rats in the normal control group and the model group. All medication was performed once daily for 21 successive days. Testes and epididymis were extracted after rats were killed and UU positive rates were compared among all groups. Sperm cells were separated using a mechanical separation technique. Sperm motility parameters were detected using color sperm motion detection system. mRNA and protein expressions of TRPV1 and TRPV5 in spermatogenic cells were determined by real-time quantitative PCR and Western blot.

RESULTSThe UU positive rate was obviously higher in the model group than in the normal control group [(86.7% (13/15 cases) vs. 0] P < 0.05). It was lower in the ZDD group [33.3% (5/15 cases)] and the azithromycin group [26.7% (4/15 cases)] than in the model group (P < 0.05). Compared with the normal control group, class A and B sperms were reduced, the linear velocity and the average velocity were significantly lowered, mRNA and protein expressions of TRPV1 and TRPV5 in spermated genic cells significantly decreased in the model group (P < 0.05). Compared with the model group, class A and B sperms were increased, linear and curve velocities and the average velocity were significantly elevated, mRNA and protein expressions of TRPV1 and TRPV5 significantly increased in the ZDD group and the azithromycin group (P < 0.05, P < 0.01). Compared with azithromycin group, class A and B sperms were increased, the linear velocity and the average velocity were significantly elevated, mRNA and protein expressions of TRPV1 and TRPV5 significantly increased in the ZDD group (P < 0.05, P < 0.01).

CONCLUSIONZDD could fight against UU infection and elevate semen quality, which might be associated with up-regulating mRNA and protein expressions of TRPV1 and TRPV5 in spermatogenic cells.

AIM: To investigate the effects of Astragalus polysacharin(APS) on human fibroblast and human umbilical vein endothelia cell (HUVEC) proliferation, as well as its acts on adhesion between white cells and HUVECs. METHODS: Human fibroblasts from distal and proximal skin away the ulcer were cultured as normal fibroblasts(NF) and wounded fibroblasts(WF). MTT assay was used for detecting cell proliferation, Rose Bengal staining and fluorescence immunohistology assay were used for examining the adhesion of human polymorpho-nuclear cell(PMN) and TPH-1 to HUVECs. RESULTS: 2 44-156 mg/L APS promoted WF proliferation, and 2 44-39 mg/L APS also promoted NF proliferation, but it did not show any proliferating effect on HUVECs. APS inhibited the adhesion of PMN or TPH-1 to HUVECs induced by tumor necrosis factor(TNF). At 25-100 mg/L, it also inhibited both VCAM-1 and ICAM-1 expression in HUVECs induced by TNF. Treatment with APS for 12 h also inhibited CD44 expression in HUVECs. CONCLUSION: APS shows mitogenic activity on both human normal and wounded fibroblasts. It also exerts anti-inflammation effects by inhibiting adhesion molecule expression and adhesion of white cells to HUVECs. [
