施氏鲟胰腺分布的初步研究

通过组织学方法对施氏鲟(Acipenser schrenckii)的胰腺在体内分布进行了研究。结果表明,施氏鲟的胰腺弥散分布于肝内、肠道及胃的周围,以肠道周围分布最多;另外脾脏内也有胰腺分布。肝脏前部无胰腺分布,中部分布较多,后部分布较少。

胰腺脂肪含量及分布与2型糖尿病发生的关系

目的:应用磁共振Dixon技术测量胰腺脂肪含量,观察胰腺脂肪含量及脂肪分布对2型糖尿病(T2DM)发生的影响,并探讨胰腺脂肪含量及其分布情况对T2DM发生的预测价值。方法:回顾性分析147例接受腹部MRI和T1加权Dixon成像检查的病人,分为T2DM组59例、风险组病人38例及对照组50例,获得胰头、胰体、胰尾脂肪分数,收集病人的年龄、性别、吸烟及饮酒史、空腹血糖(FPG)、总胆固醇(TC)、高密度脂蛋白(HDL-C)、三酰甘油(TG)、低密度脂蛋白(LDL-C)、肝功能、血清肌酐(Cr)、体质量指数(BMI),比较各组数值差异。同时按BMI水平分为BMI正常组46例、超重组79例及肥胖组22例,分析T2DM组、风险组及对照组的胰腺各部位脂肪分数的差异。并进一步做logistic回归分析,以确定胰腺脂肪分布对T2DM发生的影响。结果:T2DM组、风险组与对照组之间的年龄、吸烟及饮酒比例、BMI、ALT、AST、Cr、TC、TG、HDL-C、LDL-C差异均无统计学意义(P>0.05)。3组病人的胰腺头、体、尾部及平均脂肪分数差异均有统计学意义(P<0.05~P<0.01),T2DM组的腺头、体和平均脂肪分数均高于对照组(P<0.05~P<0.01),T2DM和风险组胰尾的脂肪分数均高于对照组(P<0.01)。在BMI正常组中,T2DM组的胰头、体、尾及平均脂肪分数均为高于对照组(P<0.05);超重组中,T2DM组胰尾和平均脂肪分数高于对照组(P<0.05);在肥胖组中,3组不同部位及平均脂肪分数差异均无统计学意义(P>0.05)。多因素logistic结果显示,胰腺尾部的脂肪分数高是T2DM的独立危险因素(OR=1.685,95%CI:1.174~2.419,P<0.01),胰头、胰体脂肪分数、BMI、TC、TG及LDL-C水平与T2DM间关联无统计学意义(P>0.05)。结论:胰腺脂肪含量增加与T2DM相关,而胰尾脂肪含量的增加也会增加T2DM的发生风险。

Perineural Invasion in Pancreatic Cancer： Advanced Research in the Neuro-cancer Interactions

Pancreatic Cancer （PCa） is characterized by prominently local nerve alterations and perineural invasion （PNI）, which frequently affects the extrapancreatic nerve plexus, causing severe pain and retropancreatic tumor extension. It precludes curative resection, promotes local recurrence, and at the last negatively influences the prognosis of patients. Recent research on PNI in PCa has revealed the critical involvement of numerous nerve- or cancer cell-derived molecules in vitro and in vivo. However, the mechanisms contributing to alteration and invasion of intrapancreatic nerves and the spread of cancer cells along extrapancreatic nerves in pancreatic cancer patients are still poorly understood. This review focuses on perineural invasion in pancreatic cancer and provides an outline of the characteristics and molecular mechanisms of perineural invasion in pancreatic cancer.

Analysis of Clinical Syndromes in 47 Patients with Pancreatic Cancer at Late Stage

Objective:To analyze the law governing the distribution of traditional Chinese medicine(TCM) syndromes of pancreatic cancer.Methods:The authors used retrospective study to statistically analyze TCM syndromes of patients,separated complex syndromes and calculated the frequency of appearance of single syndromes.Results:The patients mainly suffered from 4 syndromes:blood stasis syndrome,qi stagnation syndrome,qi(yang) deficiency syndrome,and phlegm dampness syndrome.The distribution of syndromes is rarely related to sex,age and morbid site of patients.Conclusion:Owing to complicated distribution of its syndromes,pancreatic cancer should be diagnosed and treated according to its characteristics of deficiency in origin and excess in superficiality.
