The SABC immunohistochemical method was used to observe HSP70 of mucosa around the gastric ulcer. Imaging analysis was performed. Western dot blot was used to detect HSPs contents in the plasma and gastric mucosal homogenate in each group. The results showed that HSP70 contents of the mucosa around the gastric ulcer in the model group and ranitidine treated group were increased as compared with control group . Jianpiyiqi could increase the expression of HSP70 of the mucosa around the gastric ulcer further as compared with that in the model group and ranitidine treated group . The HSP70 contents in the serum and mucosa in the model group and ranitidine treated group were increased as compared with control group ( P <0.01, P <0 05 respectively). HSP70 of serum and mucosa in the Jianpiyiqi treated group was higher than in the model group and ranitidine treated group ( P <0.05, P <0.01 respectively).It was concluded that HSP might play a role in the process of pathophysiology of gastric ulcer. Jianpiyiqi could enhance gastric ulcer healing through the protective mechanism of HSPs.展开更多

文摘目的分析创伤急诊失血性休克患者格拉斯哥昏迷评分(Glasgowcoma score,GCS)、血乳酸(lactic acid,Lac)与输血量的相关性及对患者预后的预测价值。方法回顾性收集2021年3月至2023年5月于金华市人民医院急诊医学中心诊治且完成随访的128例失血性休克患者的临床资料,按预后情况分为预后良好组(n=106)和预后不良组(n=22),比较两组患者的一般资料及GCS评分、Lac水平、输血量。采用Cox回归模型分析创伤急诊失血性休克患者预后情况的影响因素。建立受试者操作特征曲线(receiver operating characteristic curve,ROC曲线)分析GCS评分、Lac水平、输血量对创伤急诊失血性休克患者预后的预测价值。结果128例患者中预后不良22例,占比17.19%。预后不良组患者的初始24h输血量及Lac、白细胞(whitebloodcell,WBC)水平高于预后良好组,入院GCS评分、血红蛋白(hemoglobin,Hb)水平低于预后良好组,差异有统计学意义(P<0.05)。Pearson相关分析显示初始24h输血量与入院GCS评分、入院Hb水平呈负相关(P<0.05),与入院Lac水平呈正相关(P<0.05)。初始24h输血量、入院GCS评分及入院Lac、Hb水平是影响创伤急诊失血性休克患者预后的独立危险因素(P<0.05)。初始24h输血量、入院GCS评分、入院Lac、入院Hb水平及联合检测的曲线下面积(area under the curve,AUC)分别为0.722、0.872、0.881、0.798、0.931,敏感度分别为68.2%、76.6%、85.7%、75.7%、88.8%,特异性分别为70.8%、81.0%、78.5%、81.0%、85.7%。成对Z检验显示,联合检测的AUC高于单个指标检测,且敏感度和特异性均为最优(P<0.05)。结论初始24h输血量、入院GCS评分及入院Lac、Hb水平均是影响创伤急诊失血性休克患者预后不良的独立危险因素,且4项指标联合检测的效能价值最高。
