The paper, using microscopical counting method, studies the relationship between the normal reference values of 38,061 samples of red blood cell count of presenile men and eight geographical factors in 297 units in China. It is found that the correlation of geographical factors and the normal reference value of red blood cell count of presenile men is quite significant (F=303.00, P=-0.000). By using the method of stepwise regression analysis, one regression equation is inferred. It is concluded that if geographical data are obtained in a certain area, the normal reference value of red blood cell count of presenile men in this area can be reckoned by using the regression analysis. Furthermore, according to the geographical factors, China can be divided into eight regions: Northeast China Region, North China Region, Shanxi-Shaanxi-Irmer Mongolia Region, Middle and Lower Reaches of the Changjiang River Region, Southeast China Region, Northwest China Region, Southwest China Region and Qinghai-Tibet Plateau Region.展开更多
目的分析食管胃结合部腺癌(adenocarcinoma of the esophagogastric junction,AEJ)患者不同Siewert分型中RBC、NLR及临床特征。方法采用回顾性分析方法收集延安大学附属医院2017年1月1日至2018年12月31日消化内科及胃肠外科进行手术治疗...目的分析食管胃结合部腺癌(adenocarcinoma of the esophagogastric junction,AEJ)患者不同Siewert分型中RBC、NLR及临床特征。方法采用回顾性分析方法收集延安大学附属医院2017年1月1日至2018年12月31日消化内科及胃肠外科进行手术治疗的55例AEJ患者的临床病理资料,分析AEJ患者不同Siewert分型中各项指标及临床特征的变化。结果在不同Siewert分型中,RBC、NLR、肿瘤大小、淋巴结转移比较,差异有统计学意义(P<0.05)。对RBC、NLR、肿瘤大小、淋巴结转移分别进行组内两两比较,发现SiewertⅢ型中RBC值高于SiewertⅡ型,且差异有统计学意义(P<0.05);SiewertⅢ型中NLR值低于SiewertⅡ型,差异有统计学意义(P<0.05);从SiewertⅠ型到SiewertⅢ型,肿瘤的长径逐渐增大且3种Siewert分型相互之间两两比较,差异均有统计学意义(P<0.05);SiewertⅠ型到SiewertⅢ型淋巴结转移率越来越大,差异有统计学意义(P<0.05)。结论不同Siewert分型的AEJ患者具有不同的临床病理特征,SiewertⅢ型与SiewertⅡ型相比RBC水平较高,而NLR却较低;相比于另外两型,SiewertⅢ型肿瘤可能相对较大,淋巴结转移率相对较高,生物学行为可能较差。展开更多
