Getting stakeholders pertaining to change: A new understanding group strategy for making use of evidence-based, trauma-focused treatment in higher education grounds.
Accumulating evidence suggests that overexpression of heat shock protein 47 (HSP47) increases cancer progression, and that HSP47 level in the tumor-associated stroma may serve as a diagnostic marker in various cancers. The present study aimed to evaluate whether HSP47 gene expression in colorectal cancer (CRC) tissues could be used to identify lymph node (LN) metastasis status preoperatively in patients with CRC. To do so, HSP47 gene expression was determined and its association with the clinicopathological characteristics of patients with CRC was analyzed. A total of 139 surgical specimens from patients with CRC and 36 patients with benign colonic disease undergoing surgery at Mie University Hospital were analyzed. HSP47 gene expression was determined by reverse transcription quantitative PCR using Power SYBR Green PCR methods. Expression level of HSP47 was significantly higher in CRC tissues compared with normal tissue from patients with benign colonic disease. Furthermore, high HSP47 expression was significantly associated with tumor progression, including high T stage, lymph node metastasis and venous invasion, and high TNM stage. High HSP47 expression may therefore serve as a novel predictive biomarker for determining patients with CRC and LN metastasis. According to Kaplan-Meier analysis, patients with high HSP47 expression level had significantly poorer overall survival than those with low HSP47 expression level. Furthermore, multivariate analyses identified HSP47 expression as an independent predictive marker for LN metastasis and poor overall survival in patients with CRC. In summary, the present study demonstrated that HSP47 expression may be considered as a novel biomarker for predicting LN metastasis status and prognosis in patients with CRC.Glioblastoma (GBM) represents the most frequent glial tumor, with almost 3 new cases per 100,000 people per year. Despite treatment, the prognosis for GBM patients remains extremely poor, with a median survival of 14.6 months, and a 5-year survival less than 5%. selleck It is generally believed that GBM creates a highly immunosuppressive microenvironment, sustained by the expression of immune-regulatory factors, including inhibitory immune checkpoints, on both infiltrating cells and tumor cells. However, the trials assessing the efficacy of current immune checkpoint inhibitors in GBM are still disappointing. In the present study, the expression levels of several inhibitory immune checkpoints in GBM (CD276, VTCN1, CD47, PVR, TNFRSF14, CD200, LGALS9, NECTIN2 and CD48) were characterized in order to evaluate their potential as prognostic and eventually, therapeutic targets. Among the investigated immune checkpoints, TNFRSF14 and NECTIN2 were identified as the most promising targets in GBM. In particular, a higher TNFRSF14 expression was associated with worse overall survival and disease-free survival, and with a lower Th1 response.Cisplatin resistance is an obstacle for the effective treatment of non-small cell lung cancer (NSCLC). The combined use of two or more chemotherapeutic agents displays advantages for the clinical treatment of drug-resistant lung cancer. The present study aimed to assess the synergy of the dual PI3K/Akt/mTOR signaling pathway inhibitor NVP-BEZ235 and cisplatin, a chemotherapeutic agent, on proliferation, apoptosis, cell cycle arrest and protein expression in cisplatin-resistant NSCLC A549/diamminedichloroplatinum resistance (DDP) cells. Cell proliferation was determined by performing Cell Counting Kit 8 and colony formation assays. Combination index (CI) was used to assess the combinatorial effects of NVP-BEZ235 and cisplatin. Cellular apoptosis and cell cycle arrest were detected via flow cytometry. Western blotting was performed to evaluate protein expression levels relative to β-actin. Cisplatin and NVP-BEZ235 displayed the strongest synergy (CI50=0.23) at the mass ratio of 101. The half inhibitory concentrations of cisplatin and NVP-BEZ235 at 101 were 1.53 and 0.15 µg/ml, respectively. Compared with the control group, the combination of cisplatin and NVP-BEZ235 induced cell apoptosis and inhibited colony formation. Furthermore, compared with the control group, phosphorylation of Akt and p70S6 Kinase was significantly inhibited and cell cycle was arrested at G0G1 phase in the combination treatment group. The expression levels of drug efflux proteins, such as multidrug resistance-associated protein 1 and ATP-binding cassette sub-family G member 2, were significantly decreased when A549/DDP cells were treated with a combination of cisplatin and NVP-BEZ235 compared with the control group. Collectively, the present study indicated that the combined treatment of cisplatin and NVP-BEZ235 displayed synergistic antitumor effects on drug-resistant A549/DDP cells, by which the antiproliferative effects may occur via inhibition of the PI3K/Akt/mTOR signaling pathway and downregulation of drug efflux.The aim of the present study was to discuss the effect of surgery on the T-lymphocyte subsets of patients with breast cancer (BC) and investigate the association between peripheral blood αβ and γδ T-cell counts and the clinicopathological characteristics of BC. The CD3+, CD4+, CD8+ and γδ T-cell subsets in the peripheral blood of healthy volunteers and Patients with BC before and after surgery were determined using flow cytometry. The association between αβ and γδ T-cell counts in the peripheral blood and clinicopathological characteristics was analyzed by comparing the differences in the αβ and γδ T-cell counts in the peripheral blood of Patients with BC before and after surgery with those of healthy volunteers and combining with clinicopathological data. The CD3+, CD4+ and γδ T-cell counts in the peripheral blood of Patients with BC were lower compared with those in healthy volunteers (P=0.0077, 0.0116 and 0.0003, respectively), whereas the number of CD8+ cells was higher (P=0.0241). The CD3+, CD4+ and γδ T-cell counts and the CD4+/CD8+ ratio after surgery were significantly higher compared with those before surgery (P=0.0109, 0.0031, 0.0165 and 0.018, respectively). There was no significant difference between the number of CD8+ cells before and after surgery (P=0.0053), but the number of CD8+ cells was higher in healthy volunteers compared with that in Patients with BC (P10 LN metastases (P=0.0435 and 0.0283, respectively). Surgery affects the T-lymphocyte subpopulations in patients with BC, and αβ and γδ T-cell counts may increase following mastectomy. Therefore, measurement of peripheral blood lymphocyte subsets is crucial for understanding the immune function status of Patients with BC with differences in TNM stage, histological grade, cell subtypes and LN metastases, and may provide a basis for the application of T-cell subsets in the comprehensive treatment of BC.
