In this paper, the development and change trend of seller＇s credit behavior is studied by taking seller＇s behavior of cracking credit as the initial state. By a QSIM qualitative research, how the credit decision of an individual develops is found under the joint action of the credit mechanism, signal transmission mechanism, and punishment mechanism in C2C. Based on the research result, policy suggestions are proposed for the development of the online C2C credit mechanism.展开更多

目的:探讨C肽/血糖比值(CPI)与初诊2型糖尿病酮症的关系,分析初诊2型糖尿病酮症患者的临床特征,为临床上对糖尿病酮症的早期干预治疗提供参考。方法:回顾性分析2020年1—12月在江苏大学附属人民医院内分泌科住院的56例初诊2型糖尿病合...目的:探讨C肽/血糖比值(CPI)与初诊2型糖尿病酮症的关系,分析初诊2型糖尿病酮症患者的临床特征,为临床上对糖尿病酮症的早期干预治疗提供参考。方法:回顾性分析2020年1—12月在江苏大学附属人民医院内分泌科住院的56例初诊2型糖尿病合并酮症患者作为观察组,同时选取同期住院的67例初诊2型糖尿病非酮症患者作为对照组。观察两组患者初诊时体重指数(BMI)、空腹C肽/空腹血糖比值(FCPI)、糖化血红蛋白(HbA1c)、年龄等因素对尿酮体的影响。予胰岛素泵短期强化降糖后计算Δ空腹C肽/空腹血糖(ΔFCPI)、Δ餐后2 h C肽/餐后2 h血糖(ΔPCPI)水平,同时分析CPI对尿酮体的影响。结果:尿酮体与年龄(r=-0.438)、空腹C肽(r=-0.305)、FCPI(r=-0.414)呈负相关,与HBA1C(r=0.301)、空腹血糖(r=0.374)、eGFR(r=0.231)呈正相关;强化治疗后,与Δ餐后2 h C肽(r=-0.277)、ΔPCPI(r=-0.276)呈负相关。logistic回归分析结果显示,年龄、初诊时FCPI及强化治疗后ΔPCPI为初诊2型糖尿病发生酮症的危险因素(OR=0.913、0.883、0.387)。结论:发病年龄小及C肽/血糖比值低会增加初诊2型糖尿病酮症患者发病的风险,临床工作中需加强对年轻糖尿病患者的教育,重视早期胰岛功能筛查。展开更多
