In this study, we aimed to investigate the influences of conditioned medium from human umbilical vein endothelial cells (HUVEC) on cancer stem cell phenotype of human hepatoma cells. HUVEC and human hepatoma cells (MHCC97H) were cultured, respectively, and then the MHCC97H cells were co-cultured with conditioned medium from HUVEC (EC-CM) with Transwell system. Anti-cancer drug sensitivity, colony-formation, migration/invasion ability, expression of cancer stem cell marker and sphere formation were performed to determine the cancer stem cell phenotype in MHCC97H cells. We found that MHCC97H cells co-cultured with EC-CM exhibited significantly higher colony-formation ability and lower sensitivity of anti-cancer drugs 5-FU and Cis. Transwell assay showed that treatment with EC-CM obviously increased migration and invasion of MHCC97H cells. Moreover, increased sphere forming capability and expression of CD133 in MHCC97H cells were observed after co-cultured with EC-CM. These results suggested that EC-CM could promote cancer stem cell phenotype of hepatoma cells.

To observe the preventive effect of polydatin on diabetic myocardial hypertrophy in mice and discuss its and mechanism. The diabetic model was induced with low dose STZ (40 mg x kg(-1) x d(-1) x 5 d, ip) for five days in mice. The myocardial hypertrophy was determined by hypertrophy indexes (LVHI, left ventricular/right ventricle and septum), left ventricular/body weight (LV/BW), the histological examination and the mRNA expression of atrial natriuretic factor(ANF). The fast blood glucose(FBG), serum insulin and plasma hemoglobin A1c ( HbA1c) levels were detected, and then HOMA insulin resistance index ( HOMA. IR) was calculated. The mRNA and protein expressions were measured by qRT-PCR and western blotting, respectively. According to the results, the FBG of the model group exceeded 11.1 mmol x L(-1), with notable decrease in BW and significant increase in insulin, HbA1c and HOME. IR, suggesting the successful establishment and stability of the diabetic model. The increases in LVHI, LV/BW, cell surface and ANF mRNA indicated a myocardial hypertrophy in diabetic mice. Meanwhile, the model group showed decrease in mRNA and protein expressions of PPARβ and significant increase in NF-κB p65, COX-2 and iNOS expressions. After the preventation with PD (50, 100 mg x kg(-1) x d(-1)), diabetic mice showed increase in BW, reduction in the levels of FBG, insulin and HbA1 c, relief in insulin resistance and significant recovery in hypertrophy indexes, indicating PD has the protective effect in diabetic myocardial hypertrophy. Meanwhile, PD up-regulated the expression of PPARβ, inhibited the expressions of NF-κB p65, COX-2 and iNOS, demonstrating that PD's protective effect may be related to the activation of PPARβ and the inhibition of NF-κB, COX-2 and iNOS signaling pathways.

Purpose To describe the clinical and pathological features of atypical vascular lesions (AVLs) after conservative surgery and radiation of the breast cancer,and to discuss the association with post-radiation angiosarcoma.Methods The clinical and pathological features in one case of AVLs was evaluated.The literatures were reviewed.Results The patient is a 57-yeAR~-old female who underwent a conservative surgery of the right breast because of a carcinoma.She received standard dose of radiation as adjuvant therapy.Three years later, multiple erythematous plaques developed around the former scar, which radiated to the nipple.Clinically,the plaques were considered as relapses of the carcinoma.However, fine needle aspiration gave negative results.Biopsy of one large plague revealed a circumscribed vascular lesion confined to the superficial dermis.It was composed of thin-walled anastomosing lymphatic vessels lined by attenuated endothelial cells.In focal areas, the vessels extended to the mid-dermis.Immunohistochemically, the endothelial cells were positive for CD31, CD34 and D2-40,with absent of α-SMA positive pericytes.Review of the breast tumor sections showed an invasive micropapillary carcinoma.Conclusions AVLs is a rare vascular lesion related with conservative surgery and post-radiation therapy of the breast.AVLs may represent as a precursor of breast angiosarcoma.Being familiar with the clinicopathologic characteristics of AVLs is important not only for the pathologists but also for the clinicians.

AIM:To observe the image features of Vogt-Koyanagi-Harada disease (VKH) and multiple central serous chorioretinopathy (CSC) by fundus fluorescein angiography (FFA) and optical coherence tomography (OCT).METHODS:Thirty-two eyes of 17 patients with VKH and thirty-five eyes of 30 patients with multiple CSC were collected from 2009 to 2016 in my hospital.RESULTS:All the eyes with VKH were found small and dense fluorescein leakage in the early stage.The 17 eyes (53%) with VKH were found fluorescein accumulation in the final stage;24 eyes (75%) with VKH were found high fluorescence of optic disc.All of eyes with multiple CSC were found multifocal leakage in the early stage.And 2 eyes (6%) with multiple CSC were found high fluorescence of optic disc.There were 28 eyes (14 patients) with VKH and 25 eyes (22 patients) with multiple CSC had been done OCT in my hospital.Retinal pigment epithelial fold was only found in VKH.Fluctuation of internal limiting membrane (ILM) and membrane structure had higher sensitivity to diagnostic VKH from to multiple CSC, with sensitivity of 54% and 68% respectively.CONCLUSION:There are some similarities as well as differences between FFA and OCT in diagnosis of VKH and multiple CSC.A combination usage of FFA and OCT can be more effective in distinguishing VKH from multiple CSC.

This study is to investigate the anti-tumor activities of a novel cyclophosphamide derivate 4, 6-diphenyl cyclophosphamide (9b) in vivo and in vitro, and its possible mechanism of action. The inhibitory effects of 9b on human hepatoma cell line HepG2, human breast carcinoma cell line MCF-7 and human myeloid leukemia cell line K562 were measured by MTT assay in vitro. Cell cycle distribution and apoptotic rate were evaluated by flow cytometry. To evaluate the anti-tumor effect of 9b in vivo, mouse model bearing inoculated H22 tumor was established. The results indicated that 9b could inhibit the proliferation of HepG2, MCF-7 and K562 cells in a dose and time dependent manner. The ICo50 values of 9b were 32.34 micromol.L-1 to HepG2 cells, 87.07 micromol.L-1 to MCF-7 cells and 149.10 micromol.L-1 to K562 cells after incubation for 48 h. The results of flow cytometry indicated that after being treated for 48 h with different concentrations of 9b, the ratios of HepG2, MCF-7 cells at the Go/G1 phase and K562 cells at the G0/Gl phase and G2/M phase increased significantly compared with control group, and the apoptotic rate increased with the increase of the concentration of 9b. 9b could significantly reduce tumor weight of H22 solid tumor mouse model in vivo. To summarize, 9b showed significantly anti-tumor activity in vivo and in vitro, of which the mechanism might be associated with the change of cell cycle distribution and induction of tumor cell apoptosis.
