Lung cancer is the leading cause of cancer-associated mortality worldwide. In China, in particular, lung cancer mortality has markedly increased and is likely to continue to rise. RNA-binding proteins are pivotal to the development and progression of a variety of cancer types, including non-small cell lung cancer (NSCLC). RNA-binding motif protein 47 (RBM47) has been found to act as a tumor suppressor in breast cancer and NSCLC. However, to the best of our knowledge, RBM47 expression in NSCLC tissues has yet to be investigated. Analysis via the online database, Gene Expression Omnibus, revealed that RBM47 was upregulated in NSCLC and associated with pathological type, suggesting that RBM47 may play different roles in lung adenocarcinoma and lung squamous cell carcinoma. In the present study, the expression of RBM47 was examined by immunohistochemistry in 175 pairs of tumor and adjacent non-cancerous tissues resected from patients with NSCLC. The results indicated that the expression of RBM47 was significantly increased in NSCLC samples compared with that in the matched non-cancerous samples. Furthermore, RBM47 expression was higher in Xuanwei compared with that in non-Xuanwei NSCLC, suggesting that RBM47 is a more sensitive biomarker in Xuanwei NSCLC, and that it may serve as a candidate therapeutic target. In addition, RBM47 expression was associated with the pathological type, however not with the age, sex, lymph node metastasis, pT stage or pathological Tumor-Node-Metastasis stage of the patients. The increased expression level of RBM47 may indicate a worse overall survival rate for patients with NSCLC. In addition, multivariate survival analysis showed that the Xuanwei area is associated with poor prognosis for patients with NSCLC. In conclusion, the present study revealed that the upregulation of RBM47 accelerated the malignant progression of NSCLC, indicating that RBM47 may be a potential biomarker for NSCLC progression and a therapeutic target for NSCLC.
Intra-aortic balloon pumps (IABP) have saved many patients with cardiogenic shock during the perioperative period of cardiac surgery. However, the ideal insertion timing is controversial. In the present study, we aimed to optimize the insertion timing, in order to increase the survival rate of the patients. A total of 197 patients with cardiogenic shock during the perioperative period of cardiac surgery and implemented IABP from January 2011 to October 2015 were selected for the study. Patients were divided into five groups on the basis of application timing of IABP: 0–60, 61–120, 121–180, 181–240 and >240 min. The 30-day mortality, application rate of continuous renal replacement therapy (CRRT), duration of mechanical ventilation, duration of hospital stay and hospitalization charges were analyzed in the above groups. The risk factors related to mortality and the occurrence of IABP complications were also analyzed. The mortality in the 0–60, 61–120, 121–180, 181–240 and >240 min groups were 42.17, 36.6, 77.3, 72.7 and 79.3%, respectively. Earlier IABP insertion resulted in less patients receiving CRRT from acute renal failure and less daily hospitalization charges. However, the IABP application timing had no effect on indexes such as hospitalization duration, duration of mechanical ventilation and total hospitalization charges. Multifactor logistic regression analysis indicated that the independent risk factors of death in patients with cardiogenic shock during cardiac surgery were related to IABP support timing and vasoactive-inotropic score (VIS) before balloon insertion. In the first 120 min of cardiogenic shock during the perioperative period of cardiac surgery, IABP application decreased 30-day mortality. Mortality was related with VIS score of patients, which can be used to predict the prognosis of patients with cardiogenic shock.
BackgroundTransplantation with allogeneic cells has become a promising modality for cancer therapy, which can induce graft-versus-tumor (GVT) effect. This study was aimed at assessing the safety, efficacy, and tissue type GVT (tGVT) response of transplantation with allogeneic skin tumors to treat chemically-induced skin tumors in mice.Material/MethodsFVB/N and ICR mice were exposed topically to chemicals to induce skin tumors. Healthy ICR mice were transplanted with allogeneic skin tumors from FVB/N mice to test the safety. The tumor-bearing ICR mice were transplanted with, or without, allogeneic skin tumors to test the efficacy. The body weights (BW), body condition scores (BCS), tumor volumes in situ, metastasis tumors, overall survival, and serum cytokines were measured longitudinally.ResultsTransplantation with no more than 0.03 g allogeneic skin tumors from FVB/N mice to healthy ICR mice was safe. After transplantation with allogeneic skin tumors to treat tumor-bearing mice, it inhibited the growth of tumors slightly at early stage, accompanied by fewer metastatic tumors at 24 days after transplantation (21.05% vs. 47.37%), while there were no statistically significant differences in the values of BW, BCS, tumor volumes in situ, metastasis tumors, and overall survival between the transplanted and non-transplanted groups. The levels of serum interleukin (IL)-2 were significantly reduced in the controls (P<0.05), but not in the recipients, which may be associated with the tGVT response.ConclusionsOur results suggest that transplantation with allogeneic skin tumors is a safe treatment in mice, which can induce short-term tGVT response mediated by IL-2.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
