R. China

Background: The prognostic nutritional index(PNI) has been widely applied for predicting survival outcomes of patients with various malignant tumors. Although a low PNI predicts poor prognosis in patients with colorectal cancer after tumor resection, the prognostic value remains unknown in patients with stage Ⅲ colon cancer undergoing curative tumor resection followed by adjuvant chemotherapy. This study aimed to investigate the prognostic value of PNI in patients with stage III colon ***: Medical records of 274 consecutive patients with stage Ⅲ colon cancer undergoing curative tumor resection followed by adjuvant chemotherapy with oxaliplatin and capecitabine between December 2007 and December2013 were reviewed. The optimal PNI cutoff value was determined using receiver operating characteristic(ROC) curve analysis. The associations of PNI with systemic inflammatory response markers, including lymphocyte-to-monocyte ratio(LMR), neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR), and C-reactive protein(CRP)level, and clinicopathologic characteristics were assessed using the Chi square or Fisher's exact test. Correlation analysis was performed using Spearman's correlation coefficient. Disease-free survival(DFS) and overall survival(OS)stratified by PNI were analyzed using Kaplan-Meier method and log-rank test, and prognostic factors were identified by Cox regression ***: The preoperative PNI was positively correlated with LMR(r= 0.483, P < 0.001) and negatively correlated with NLR(r =-0.441, P < 0.001), PLR(r =-0.607, P < 0.001), and CRP level(r =-0.333, P < 0.001). A low PNI(≤49.22)was significantly associated with short OS and DFS in patients with stage ⅢC colon cancer but not in patients with stage ⅢA/ⅢB colon *** addition, patients with a low PNI achieved a longer OS and DFS after being treated with6-8 cycles of adjuvant chemotherapy than did those with < 6 cycles.

Background: Voltage-gated sodium channel 1.5(Nav1.5) potentially promotes the migratory and invasive behaviors of colon cancer cells. Hitherto, the prognostic significance of Nav1.5 expression remains undetermined. The present study aimed to explore the associations of Nav1.5 expression with clinical outcomes and estrogen receptor-β(ER-β)expression in non-metastatic colon cancer patients receiving radical ***: A total of 269 consecutive patients with pathologically confirmed stages Ⅰ-Ⅲ colon cancer who underwent radical resection were selected. Nav1.5 and ER-β expression was detected by using immunohistochemistry(IHC)on tissue microarray constructed from paraffin-embedded specimens. IHC score was determined according to the percentage and intensity of positively stained cells. Statistical analysis was performed with the X-tile method, k coefficient, Chi square test or Fisher's exact test, logistic regression, log-rank test, and Cox proportional hazards ***: We found that Nav1.5 was commonly expressed in tumor tissues with higher mean IHC score as compared with matched tumor-adjacent normal tissues(5.1 ± 3.5 vs. 3.5 ± 2.7, P < 0.001).The high expression of Nav1.5 in colon cancer tissues was associated with high preoperative carcinoembryonic antigen level [odds ratio(OR) = 2.980;95% confidential interval(CI)1.163-7.632; P = 0.023] and high ER-β expression(OR = 2.808; 95% CI 1.243-6.343;p = 0.00 3). Log-rank test results showed that high Nav1.5 expression contributed to a low 5-year disease-free survival(DFS) rate in colon cancer patients(77.2% vs. 92.1%, P = 0.048), especially in patients with high ER-β expression tumor(76.2% vs. 91.3%, P = 0.032). Analysis with Cox proportional hazards model demonstrated that high Nav1.5 expression[hazard ratio(HR) = 2.738; 95% CI 1.100-6.819;P = 0.030] and lymph node metastasis(HR = 2.633; 95% CI 1.632-4.248; P < 0.001) were prognostic factors for unfavorable DFS in colon cancer ***: High ex

背景与目的预后营养指数(prognostic nutritional index,PNI)已广泛应用于预测各种恶性肿瘤患者的生存结局。虽然低PNI预测肿瘤切除后的结直肠癌患者的预后不良,但对接受根治性肿瘤切除术后辅助化疗的Ⅲ期结肠癌患者的预后价值仍未知。本研究旨在探讨PNI对Ⅲ期结肠癌患者的预后价值。方法本文回顾了2007年12月至2013年12月期间,274例接受根治性肿瘤切除术后接受奥沙利铂和卡培他滨辅助化疗的Ⅲ期结肠癌的连续患者的医疗记录。采用受试者工作特征(receiver operating characteristic,ROC)曲线分析确定最佳PNI临界值。采用卡方检验或Fisher’s精确检验评估PNI与全身炎症反应标志物[包括淋巴细胞与单核细胞比值(lymphocyte-to-monocyte ratio,LMR)、中性粒细胞与淋巴细胞比值(neutrophil-to-lymphocyte ratio,NLR)、血小板与淋巴细胞比值(platelet-to-lymphocyte ratio,PLR)、C反应蛋白(C-reactive protein,CRP)水平]和临床病理特征的相关性。采用Spearman’s相关系数进行相关分析。采用Kaplan-Meier法和log-rank检验分析PNI分层的无病生存期(disease-free survival,DFS)和总生存期(overall survival,OS),并通过Cox回归分析确定预后因子。结果术前PNI与LMR呈正相关(r=0.483,P <0.001),与NLR(r=-0.441,P <0.001)、PLR(r=-0.607,P <0.001)和CRP水平(r=-0.333,P <0.001)呈负相关。在ⅢC期结肠癌患者中,低PNI(≤49.22)与短OS和DFS显著相关,而在ⅢA/ⅢB期结肠癌患者中则不相关。此外,在PNI低的患者中,接受6–8个疗程辅助化疗的患者比接受<6个疗程治疗的患者获得了更长的OS和DFS。多变量分析显示PNI与DFS独立相关(风险比=2.001;95%置信区间:1.157–3.462;P=0.013)。结论术前PNI是接受根治性肿瘤切除术后辅助化疗的Ⅲ期结肠癌患者生存结局的重要预测指标。

摆臂是摆锤设备非常重要的运动部件和承载结构,常规设计中对摆臂的计算较为简略,一般采用较为保守的方式设计结构,造成了一定的材料浪费,有时因为对摆臂受力认识不足,为结构设计埋下风险。在已详细分析摆锤运动过程的前提下,得到摆锤运动过程中精确的运动参数,以摆臂-转盘模型详细计算了运动过程中摆臂的受力。在已知外荷载、摆锤角位移、运动角速度与角加速度的情况下,计算各部分结构的转动惯量,通过刚体动力学分析,运用刚体的平面运动微分方程,先计算转盘对摆臂的荷载,再分析得到摆臂任一截面的荷载。由每一时刻的运动参数计算可得摆臂任一截面的荷载谱,为摆锤设备的安全校核提供了更准确的截面荷载,也可作为新设计的参考。

背景与目的我们的Ⅱ期随机试验的初步研究结果显示,对进行全直肠系膜切除术(total mesorectal excision,TME)的患者是/否进行术前同步放化疗(concurrent chemoradiotherapy,CCRT),二者的功能性括约肌保留率和短期生存结局相近。在经过中位71个月的随访后,现报告这一长期试验的结果。方法在2008年3月23日至2012年8月2日期间,192例患有T3–T4或淋巴结阳性、可切除的中/低直肠腺癌患者被随机分为接受或不接受术前CCRT组,之后均进行TME。评估以下终点:局部复发和远处转移的累积率、无病生存(disease?free survival,DFS)和总生存(overall survival,OS)。结果对入组的184例患者资料进行分析,其中TME组有94例,CCRT+TME组有90例。在整个队列中,5年DFS和OS率分别为84.8%和85.1%。CCRT+TME组的5年DFS率为85.2%,TME组为84.3%(P=0.969);CCRT+TME组的5年OS率为83.5%,TME组为86.5%(P=0.719)。在CCRT+TME和TME组中,局部复发的5年累积率分别为6.3%和5.0%(P=0.681),远处转移的5年累积率分别为15.0%和15.7%(P=0.881)。通过亚组分析,接受CCRT未观察到5年DFS和OS的显著改善。结论两种治疗方案的长期结局相近。因此,如果可以进行高质量的TME手术和强化化疗,建议选择性地对直肠癌患者进行术前CCRT。
