BACKGROUND The relationship between preoperative inflammation status and tumorigenesis as well as tumor progression is widely *** To assess the prognostic significance of preoperative inflammatory biomarkers in patients with distal cholangiocarcinoma(dCCA)who underwent pancreat-oduodenectomy(PD).METHODS This single-center study included 216 patients with dCCA after PD between January 1,2011,and December 31,*** individuals were categorized into two sets based on their systemic inflammatory response index(SIRI)levels:A low SIRI group(SIRI<1.5,n=123)and a high SIRI group(SIRI≥1.5,n=93).Inflam-matory biomarkers were evaluated for predictive accuracy using receiver operating characteristic *** univariate and multivariate Cox proportional hazards analyses were performed to estimate SIRI for overall survival(OS)and recurrence-free survival(RFS).RESULTS The study included a total of 216 patients,with 58.3%being male and a mean age of 65.6±9.6 years.123 patients were in the low SIRI group and 93 were in the high SIRI group after PD for *** had an area under the curve value of 0.674 for diagnosing dCCA,showing better performance than other inflammatory *** analysis indicated that having a SIRI greater than 1.5 independently increased the risk of dCCA following PD,leading to lower OS[hazard ratios(HR)=1.868,P=0.006]and RFS(HR=0.949,P<0.001).Additionally,survival analysis indicated a significantly better prognosis for patients in the low SIRI group(P<0.001).CONCLUSION It is determined that a high SIRI before surgery is a significant risk factor for dCCA after PD.

Combining the deviation between thin layers' adjacent surfaces with the confining potential method applied to the quantum curved systems,we derive the effective Schr?dinger equation describing the particle constrained within a curved layer,accompanied by a general geometric potential V_(gq) composed of a compression-corrected geometric potential V_(gq)~*and a novel potential V_(gq)~(**) brought by the *** this analysis to the cylindrical layer emerges two types of deviation-induced geometric potential,resulting from the the cases of slant deviation and tangent deviation,respectively,which strongly renormalizes the purely geometric potential and contribute to the energy spectrum based on a very substantial deepening of bound states they offer.

通过测定群落中植物叶干物质含量、比叶面积、叶面积、叶宽、叶长、叶厚度、高度、盖度8个功能性状,计算出功能性状距离、功能性状平均距离、功能体积、功能均匀度指数、功能分散指数、Rao二次熵指数6个功能多样性指数,对山西七里峪森林群落的功能多样性进行研究。结果表明:(1)杨桦林的功能丰富度指数普遍较高,野核桃林和辽东栎林居中,针叶林最低,说明与演替阶段有关;(2)3个功能丰富度指数均与物种丰富度、香农指数呈显著正相关;2个功能离散度也与香农指数、物种均匀度呈显著正相关,说明功能多样性的差异很大程度上是由于物种(数量上和组成上)差异所引起的;(3)根据主成分分析可知,第1主成分可看作是功能丰富度因子,第2主成分可看作是功能离散度因子,第3主成分可看作是功能均匀度因子。该结果说明三类指数内部自相关,且与其他指数相对独立。
