Abstract
BACKGROUND Pancreatic cancer (PC) is among the most prevalent and deadliest endocrine tumors, yet the mechanisms governing its pathogenesis remain to be fully clarified. While ubiquitin-conjugating enzyme E2C (UBE2C) has been identified as an important oncogene in several cancers, its importance in PC has yet to be established. METHODS UBE2C expression in PC tumor samples and cell lines was examined via quantitative real-time polymerase chain reaction (qRT-PCR), while appropriate commercial kits were used to assess lactate production, ATP generation, and the uptake of glucose. RESULTS UBE2C was found to be upregulated in PC patient tumors and correlated with poorer survival outcomes. In PC cell lines, the silencing of this gene suppressed the malignant activity of cells, thus supporting its identification as an oncogene in this cancer type. Mechanistically, UBE2C was found to promote enhanced matrix metalloproteinase (MMP) protein expression via activating the PI3K-Akt pathway. Moreover, it was found to bind to the epidermal growth factor receptor (EGFR), stabilizing it and driving additional PI3K-Akt pathway activation. UBE2C knockdown in PC cells impaired their uptake of glucose and their ability to produce lactate and ATP. CONCLUSIONS In conclusion, the results of this study support a role for UBE2C as a driver of metastatic PC progression owing to its ability to bind to EGFR and to induce signaling via the PI3K-Akt pathway.

Abstract
Background For patients with colon or stomach adenocarcinoma, 5-fluorouracil (5-FU) is an essential component of systemic chemotherapy in the palliative and adjuvant settings. The post-transcriptional regulatory factor cytoplasmic polyadenylation element-binding protein 1 (CPEB1) has been reported to be linked to tumor metastasis. This study aimed to investigate the relationship between CPEB1 expression and 5-FU treatment response in patients with colon and stomach adenocarcinomas. Methods The expression of CPEB1 in stomach adenocarcinoma and colorectal cancer (CRC) tissues and in cell lines was determined by quantitative real-time PCR (qRT-PCR) and immunohistochemistry analyses. Transwell assays were employed to analyze the effects of CPEB1 on the migration and invasion abilities of gastric cancer (GC) and CRC cells. Results The expression levels of CPEB1 were increased in colon and stomach adenocarcinoma and were negatively correlated with malignancy and poor patient survival. Data suggested that patients with CRC or GC who had strong CPEB1 expression responded poorly to 5-FU treatment. Furthermore, knockdown of CPEB1 inhibited the migration and invasion of CRC and GC cells via a mechanism involving decreased expression of matrix metalloprotein (MMP)2, 7, and 9. Finally, our methylated RNA immunoprecipitation PCR (meRIP qPCR) data suggested that the increased CPEB1 expression in colon and stomach adenocarcinomas might be mediated by FTO (FTO alpha-ketoglutarate dependent dioxygenase)-dependent m6A demethylation of CPEB1 mRNA. Conclusions Our results indicate that the level of CPEB1 expression may be valuable for predicting the benefit of 5-FU treatment for patients with colon and stomach adenocarcinomas. We therefore propose that low CPEB1 expression may represent a novel biomarker for personalized 5-FU therapy.

Abstract
Objective: To evaluate the prognosis and determine the failure patterns after radiotherapy for low-risk early-stage patients with extranodal NK/T-cell lymphoma, nasal-type (ENKTCL). Methods: A total of 557 patients from 2000-2015 with low-risk early-stage ENKTCL who received radiotherapy (RT) with or without chemotherapy (CT) from China Lymphoma Collaborative Group were retrospectively reviewed. Among them, 427 patients received combined modality therapy, whereas 130 patients received RT alone. Survivals were calculated by Kaplan-Meier method and compared with Log-rank test. Overall survival (OS) was compared with age and sex-matched general Chinese population using expected survival and standardized mortality ratio (SMR). Cox stepwise regression model was used for multivariate analysis. Results: The 5-year OS and progression-free survival (PFS) were 87.2% and 77.2%. The SMR was 3.59 (P<0.001) at 1 year after treatment, whereas it was 1.50 at 4 years after treatment, without significant difference between ENKTCL group and country-matched general population (P=0.146). Compared with RT alone, CMT did not result in significantly superior 5-year OS (87.0% vs 87.4%, P=0.961) or PFS (76.1% vs 80.7%, P=0.129). Local failure (11.5%, 64/557) and distant failure (10.8%, 60/557) were the main failure modes, while regional failure was rare (2.9%, 16/557). The 5-year locoregional control rate (LRC) was 87.2% for the whole group, with 89.5% for ≥50 Gy versus 73.7% for <50 Gy (P<0.001). Radiotherapy dose was an independent factor affecting LRC(P<0.05). Conclusions: Radiotherapy achieves a favorable prognosis in patients with low-risk early-stage ENKTCL. The incidence of either locoregional or distant failure is low. Radiation dose still is an important prognostic factor for LRC.

Abstract
Objective: To evaluate the value of the age-adjusted Charlson comorbidity Index (ACCI) in predicting the prognosis and guiding the clinical treatment of laryngeal squamous cell carcinoma (LSCC) in patients over 60 years old. Methods: Retrospective analysis of 249 cases of LSCC in Shanxi Provincial Cancer Hospital and First Hospital of Shanxi Medical University from 2008 to 2015 was performed. There were 234 males and 15 females, aged from 60 to 88 years. The clinical characteristics, treatment information and follow-up data were collected. ACCI was used to score the comorbidities of the patients. Receiver operating characteristic (ROC) curve was drawn and the patients were divided into high ACCI group and low ACCI group according to the cut-off value of ACCI. Prognostic factors were analyzed. Kaplan-Meier method was used for survival analysis, rank sum test was used for comparison between groups, χ2 test was used for enumeration data. Results: Overall survival (OS) was 54.6%, progression-free survival (PFS) was 59.4%, and cancer-specific survival (CSS) was 58.6%. Both the median survival time and PFS time were 60 months. The best cutoff point of the ACCI group was 5. Cox multivariate analysis showed that ACCI was an independent risk factor for OS, PFS and CSS (OR=1.553, 1.499 and 1.534,respectively, all P<0.05). In the high ACCI group, OS (χ2=4.120 and 4.115,P<0.05) and CSS (χ2=4.510 and 5.009,P<0.05) of patients treated with surgery plus radiotherapy and patients with radiotherapy alone were better than those of patients with surgery alone (P<0.05). But in the low ACCI group, there was no significant difference in prognosis among the three treatment regimens (P>0.05). Conclusion: High ACCI offors important prognostic information for LSCC in patients over 60 years old, and can guide clinical treatment options.

Abstract
BACKGROUND This study evaluated the survival benefit of asparaginase (ASP)-based versus non-ASP-based chemotherapy combined with radiotherapy in a real-world cohort of patients with early-stage extranodal nasal-type natural killer/T-cell lymphoma (ENKTCL). PATIENTS AND METHODS We identified 376 patients who received combined radiotherapy with either ASP-based (ASP, platinum, and gemcitabine; n = 286) or non-ASP-based (platinum and gemcitabine; n = 90) regimens. The patients were stratified into low-, intermediate-, and high-risk groups using the early stage-adjusted nomogram-revised risk index. Overall survival (OS) and distant metastasis (DM)-free survival (DMFS) between the chemotherapy regimens were compared using inverse probability of treatment weighting (IPTW) and multivariable analyses. RESULTS ASP-based (versus non-ASP-based) regimens significantly improved 5-year OS (84.5% versus 73.2%, P = 0.021) and DMFS (84.4% versus 74.5%, P = 0.014) for intermediate- and high-risk patients, but not for low-risk patients in the setting of radiotherapy. Moreover, ASP-based regimens decreased DM, with a 5-year cumulative DM rate of 14.9% for ASP-based regimens compared with 25.1% (P = 0.014) for non-ASP-based regimens. The survival benefit of ASP-based chemotherapy and radiotherapy remained consistent after adjusting the confounding variables using IPTW and multivariate analyses; additional sensitivity analyses confirmed these results. CONCLUSIONS The findings provided support for ASP-based chemotherapy and radiotherapy as a first-line treatment strategy for intermediate- and high-risk early-stage ENKTCL.

Abstract
Objective: To investigate the relationship between the status of epidermal growth factor receptor (EGFR) mutations and brain metastases in patients with lung adenocarcinoma. Methods: From August 2010 to May 2015, a total of 1 063 lung adenocarcinoma patients with identified status of EGFR mutations in Shanxi Cancer Hospital were enrolled, of which 456 patients had EGFR mutations. Multivariate Logistic regression model was used to analyze the correlation between EGFR mutation status and brain metastases in patients with lung adenocarcinoma. Results: In 125 patients with brain metastases before initial treatment, 65 patients had EGFR mutations, including 36 patients with deletion mutations in exon 19. The frequency of EGFR 19 exon mutation was 28.8% (36/125). Among 456 patients with EGFR mutations, 65(14.3%) patients were with brain metastases, in which 36(55.0%) had deletion mutations in exon 19. The multivariate analysis showed that age, Eastern Cooperative Oncology Group (ECOG) score, EGFR mutations and N staging were associated with brain metastases(P<0.05). Further subgroup multivariate analyses showed that age, ECOG score, mutation status in exon 19 and N staging were associated with brain metastases (P<0.05). Conclusions: EGFR mutation status is related to brain metastases. Mutations in EGFR exon 19 is an independent risk factor for brain metastases.

Abstract
OBJECTIVE This study aimed to evaluate the impact of technical advancement of radiation therapy in patients with LA-NSCLC receiving definitive radiotherapy (RT). METHODS Patients treated with definitive RT (≥50 Gy) between 2000 and 2010 were retrospectively reviewed. Overall survival (OS), cancer specific survival (CSS), locoregional progression-free survival (LRPFS), distant metastasis-free survival (DMFS) and progression-free survival (PFS) were calculated and compared among patients irradiated with different techniques. Radiation-induced lung injury (RILI) and esophageal injury (RIEI) were assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events 3.0 (NCI-CTCAE 3.0). RESULTS A total of 946 patients were eligible for analysis, including 288 treated with two-dimensional radiotherapy (2D-RT), 209 with three-dimensional conformal radiation therapy (3D-CRT) and 449 with intensity-modulated radiation therapy (IMRT) respectively. The median follow-up time for the whole population was 84.1 months. The median OS of 2D-RT, 3D-CRT and IMRT groups were 15.8, 19.7 and 23.3 months, respectively, with the corresponding 5-year survival rate of 8.7%, 13.0% and 18.8%, respectively (P<0.001). The univariate analysis demonstrated significantly inferior OS, LRPFS, DMFS and PFS of 2D-RT than those provided by 3D-CRT or IMRT. The univariate analysis also revealed that the IMRT group had significantly loger LRPFS and a trend toward better OS and DMFS compared with 3D-CRT. Multivariate analysis showed that TNM stage, RT technique and KPS were independent factors correlated with all survival indexes. Compared with 2D-RT, the utilization of IMRT was associated with significantly improved OS, LRPFS, DMFS as well as PFS. Compared with 3D-CRT, IMRT provided superior DMFS (P=0.035), a trend approaching significance with regard to LRPFS (P=0.073) but no statistically significant improvement on OS, CSS and PFS in multivariate analysis. The incidence rates of RILI were significantly decreased in the IMRT group (29.3% vs. 26.6% vs.14.0%, P<0.001) whereas that of RIET rates were similar (34.7% vs. 29.7% vs. 35.3%, P=0.342) among the three groups. CONCLUSIONS Radiation therapy technique is a factor affecting prognosis of LA-NSCLC patients. Advanced radiation therapy technique is associated with improved tumor control and survival, and decreased radiation-induced lung toxicity.

Abstract
Several previous studies have shown that 1 to 2 weeks of treatment with ethanol elicits tolerance to several effects produced by ethanol and cross-tolerance to nicotine-induced hypothermia. Similarly, short-term, high-dose nicotine treatment produces tolerance to nicotine and cross-tolerance to ethanol-induced hypothermia. In the studies reported here, C57BL/6 mice were force-fed ethanol, nicotine, or an ethanol/nicotine combination in the drinking water for 6 months. All of the chronic drug-treated mice developed tolerance to ethanol as measured by open-field activity, body temperature, and sleep-time tests. Ethanol tolerance is due, in part, to enhanced metabolism and reduced CNS sensitivity in the two ethanol-treated groups but only to reduced CNS sensitivity in the nicotine-treated group. Similar levels of tolerance to nicotine developed in those two groups that were nicotine-treated, but no tolerance to nicotine was seen in those animals treated with ethanol alone. The tolerance to nicotine may be related to an upregulation of brain (cortex, hippocampus, and hypothalamus) [3H]-nicotine binding, but ethanol tolerance is not readily explained by changes in the number of the brain high affinity nicotine binding sites.

Abstract
Dynamic changes of contents of beta-endorphin, leu-enkephalin and oxytocin in plasma were determined in seventeen fracture patients with shock, fascial space syndromes, or infection postoperation. There was significant rise of contents in beta-endorphin and leu-enkephalin but not in oxytocin after trauma, Of those accompanied by infection postoperation, beta-endorphin and oxytocin remained high. The contents of beta-endorphin and enkephalin decreased gradually in non-infectious group, but were still higher than normal. The most obvious change was seen in beta-endorphin, suggesting that beta-endorphin plays a more important role in trauma. This was also confirmed in rat injury model.
