Background: Present study aimed to better understand the potential apoptotic pathways that involved in docosahexaenoic acid (DHA)-induced apoptosis of prostate cancer cells. Methods: Human prostate cancer DU145 cells were treated with different concentrations of fish oil, omega-3 PUFA (DHA, and Eicosapentaenoic acid, EPA), or omega-6 PUFA (Arachidonic acid, AA). Cell viability and apoptosis were evaluated by MTT assay and Hoechst staining. Pathway-focused gene expression profiling of DU145 cells was analyzed with the RT2 Profile PCR Array System. The results were verified by real time quantitative polymerase chain reaction (RT-qPCR). Results: AA exposure showed no obvious effect on viability of DU145 cells. However, exposure with fish oil, EPA, or DHA for 24 h significantly affected cell viability. The growth inhibition of DHA was more pronounced than that of EPA and showed a time-dependent increase. DHA exposure caused typical apoptotic characteristics. Ten genes were more expressed, while 5 genes were less expressed following DHA exposure. RT-qPCR confirmed the time dependent effect of DHA on the expression of these differentially expressed genes. KEGG pathway analysis showed that DHA may induce the apoptosis of cancer cells preferentially through mediating P53, MAPK, TNF, PI3K/AKT, and NF-κB signaling pathways. Conclusion: Our study demonstrated the beneficial action of DHA on human prostate carcinoma cell line DU145. The pro-apoptotic effect of DHA on DU145 cells may involve mediation various pathways, especially P53, MAPK, TNF, PI3K/AKT, and NF-κB signaling pathways. Molecular mechanisms of DHA on apoptosis of cancer cells still need to be further clarified. © 2017 The Author(s).

OBJECTIVE: To evaluate the curative effect and safety of Bushen Qiangji Decoction (BQD) and Qingre Qiangji Decoction (QQD) in treating ankylosing spondylitis (AS) patients, and to verify the clinical utility of AS syndrome differentiation and treatment scheme [Shen-deficiency induced stasis obstruction syndrome (SDISOS) and dampness-heat obstruction syndrome (DHOS) being two basic syndrome types, Shen invigorating blood activating method (SIBAM) and heat clearing dampness resolving method (HCDRM) being two basic treatment methods].METHODS: Totally 354 AS patients of SDISOS and DHOS were randomly assigned to the treatment group and the control group using a multi-center randomized, positive drug parallel-controlled clinical trail. Patients in treatment group were treated by BQD or QQD according to syndrome typing, while those in the control group took Sulfasalazine enteric-coated tablet (SECT), 24 weeks as one therapeutic course. After treatment, the clinical efficacy was evaluated by using ASAS20 standard (set by Asessment in Ankylosing Spondylitis working group), Chinese medical efficacy evaluation standards, and BASDAI, BASFI, BASMI, night-pain index, spinal pain index, PGA, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR).RESULTS: After 24 weeks of treatment by BQD or QQD, ASAS20 standard rate was 86.75% in the treatment group, and the total effective rate of Chinese medical syndrome was 85.47%. They could significantly reduce patients' integrals of Chinese medical syndrome, BASDAI, BASFI, BASMI, night-pain index, spinal pain index, and PGA (all P < 0.01).CONCLUSIONS: QQD and BQD got confirmable clinical effects in treating AS, providing strong evidence of evidence-based medicine for syndrome differentiation and treatment of AS.

Use of the tyrosine kinase inhibitor sorafenib in patients with advanced hepatocellular carcinoma (HCC) is often hindered by the development of resistance, which has been recently shown to be associated with the emergence of a cancer stem cell (CSC) subpopulation. However, it remains largely unknown whether epigenetic mechanisms, especially histone posttranslational modifications, are causally linked to the maintenance of stem-like properties in sorafenib-resistant HCC. In this study, we report that the activity of lysine-specific histone demethylase 1A (KDM1A or LSD1) is required for the emergence of cancer stem cells following prolonged sorafenib treatment. As such, KDM1A inhibitors, such as pargyline and GSK2879552, dramatically suppress stem-like properties of sorafenib-resistant HCC cells. Mechanistically, KDM1A inhibitors derepress the expression of multiple upstream negative regulators of the Wnt signaling pathway to downregulate the β-catenin pathway. More importantly, KDM1A inhibition resensitizes sorafenib-resistant HCC cells to sorafenib in vivo, at least in part through reducing a CSC pool, suggesting a promising opportunity for this therapeutic combination. Together, these findings suggest that KDM1A inhibitors may be utilized to alleviate acquired resistance to sorafenib, thus increasing the therapeutic efficacy of sorafenib in HCC patients. © 2017 Elsevier B.V.

Objective: To investigate the expression of vasculogenic mimicry (VM) in endometrial carcinoma tissues and its relationship with the clinicopathologic features and prognosis of the disease. Methods: A total of 267 paraffin-embedded endometrial carcinoma specimens of patients with complete follow-up data were collected from the Shijiazhuang Bethune International Peace Hospital between January 2005 and June 2014. CD31-PAS dual staining was performed to identify the VM structure. Tissue samples were then divided into VM-positive and VM-negative groups. CD133 expression was detected by immunohistochemical streptavidin peroxidase method. Results: Among the 267 endometrial carcinoma patients, 65 cases (24.3%) were VM positive. VM formation was closely correlated with the International Federation of Gynecology and Obstetrics Staging (χ2=9.987, P=0.002), histodifferentiation grade (χ2= 11.795, P=0.001), myometrial invasion depth (χ2=5.499, P=0.019), vascular cancer embolus (χ2=22.599, P<0.001), and lymph node metastasis (χ2=7.848, P=0.005). Kaplan-Meier survival curve analysis showed that survival time was significantly shorter in the VM-positive group (median survival time was 51 months) than in the VM-negative group (median survival time was 100 months) (χ2=70.973, P< 0.001). Moreover, CD133 expression was significantly higher in the VM-positive group [75.4% (49/65)] than in the VM-negative group [58.9% (119/202)] (χ2=5.720, P=0.017). Conclusion: VM is closely correlated with the pathogenesis, development, and malignancy of endometrial carcinoma. Furthermore, VM is one of the important indexes influencing the prognosis of this disease. Therefore, CD133 positive cells may contribute to VM formation.

Purpose: To report the results of a safety analysis from a phase II trial comparing administration of weekly paclitaxel plus S-1 (TS) versus paclitaxel plus 5-fluorouracil (5-FU)/calcium folinate (LV) (TLF) as first-line therapy for advanced gastric cancer. Methods: Patients (n5240) with previously untreated advanced gastric cancer were randomly assigned to receive either TS or TLF in a 28-day cycle for six cycles. Results: The clinical features of both sets of patients were similar, with the exception of the incidence of prior chemotherapy (P>0.05). Most treatment-related adverse events occurred at similar rates in both treatment arms. However, patients receiving TS experienced an increase in all-grade especially grade 3/4 neutropenia, with an incidence of 43.7% in the TS arm and 16.3% in the TLF arm, respectively (P<0.05). Other severe adverse events were infrequent and not significantly different between the groups. Conclusion: The safety and tolerance of weekly paclitaxel plus S-1 or 5-FU/LV is well in untreated advanced gastric cancer patients. © 2013 Edizioni Scientifiche per l'Informazione su Farmaci e Terapia.
