目的：分析急性有机磷农药中毒（AOPP）引发缺血缺氧性脑病预后相关因素，建立相关的预后预测模型。方法：回顾性分析90例（33例预后不良、57例预后良好）AOPP致HIE患者（2022年3月～2025年8月）的临床资料、中毒指标和血清学指标，独立危险因素用Logistic回顾分析筛选，并构建预后不良预测模型，采用ROC工具对模型效能进行验证。结果：Logistic 回归分析显示，年龄≥60岁、重度中毒、中毒至就诊时间、LAC水平、CHE水平、CRP水平及NSE水平均为患者预后不良的独立危险因素（P＜0.05）；AUC、灵敏度、特异度为0.943、90.91%、87.72%。结论：高龄、中毒程度高及中毒至就诊时间长等因素可导致AOPP致HIE患者出现不良结局，据此构建风险预测模型可有效预测预后不良的发生风险。

To determine the key impacting factors for hypoxic ischemic encephalopathy (HIE) caused by acute organophosphorus pesticide poisoning (AOPP) and build a prediction model. Methods: The clinical data, poisoning indicators and serological indicators of 90 patients (33 cases with poor prognosis and 57 cases with good prognosis) with HIE caused by AOPP (from March 2022 to Aug 2025) were analyzed. Independent risk factors were screened using logistic retrospective analysis, and a poor prognosis prediction model was constructed. The model efficiency was verified by the receiver operating curve (ROC). Results: Logistic regression analysis showed that age ≥ 60 years, severe poisoning, time from poisoning to treatment, LAC level, CHE level, CRP level, and NSE level were all risk factors for the prognosis in patients (P < 0.05). The AUC, sensitivity, and specificity were 0.943, 90.91%, and 87.72%.Conclusion: Factors such as advanced age, high degree of poisoning, and long time from poisoning to treatment can lead to adverse outcomes in patients with HIE caused by AOPP. Based on this, building a risk prediction model can effectively predict the risk of poor prognosis.

目的 观察和评价重症毒蕈中毒(PMP)患者的临床资料,探讨血液灌流(HP)联合血液滤过(HF)与单独血液滤过治疗的疗效比较。方法 收集本院2016年8月—2018年10月救治的32例重症急性毒蕈中毒并发中毒性肝损伤、急性肾衰竭、中毒性心肌炎、消化道出血、中毒性脑病、急性血管内溶血等患者的临床资料,将32例患者分为治疗组和对照组,治疗组14例,采用持续静脉-静脉血液滤过24 h串联灌流2 h;对照组18例,采用单独血液滤过24 h,疗程2～3 d。两组患者内科常规治疗基本相同。结果 14例治疗组在内科常规治疗基础上联合血液灌流+血液滤过,好转率为92.9%(13/14);18例对照组在内科常规治疗基础上单用血液滤过,好转率为61.1%(11/18),两组好转率比较,差异有统计学意义(P<0.05)。治疗组患者黄疸、少尿、黑便、意识障碍等症状减轻,优于对照组;血清AST、ALT、TBil、DBil、PT、APTT水平较治疗前改善,优于对照组,差异有统计学意义(P均<0.05)。结论 毒蕈中毒患者常合并多脏器功能障碍(MODS),及早进行血液灌流联合血液滤过治疗较单独血液滤过能更有效的清除蛋白结合毒素和血清炎症因子,从而减轻内脏器官损害,改善肝、肾和凝血功能,治疗效果显著。

Objective To compare the clinical effect differences between hemoperfusion combined with hemofiltration with simple hemofiltration in treatment of severe mushroom poisoning patients. Methods 32 patients with toxic hepatitis,toxic myocarditis,toxic encephalopathy and acute renal failure due to poisonous mushroom were divided into two groups: treating group(n=14) and control group(n=18).Patients of treating group received continuous veno-venous hemofiltration for 24 hours combined with hemoperfusion for 2 hours.The cases of control group only received hemofiltration for 24 hours. Results After the treatment,the improvement rate in treating group were higher than that in control group(P<0.05).The disturbance of consciousness,jaundice,oliguria,melena in treating group were improved obviously and serum levels of AST、ALT、TBil、DBil、PT、APTT were reduced than those in controls(P<0.05). Conclusion Compared with simple hemofiltration,early hemoperfusion combined with hemofiltration for patients with severe toadstool poisoned can not only remove protein binding toxin and serum inflammatory factors,but also improve liver,kidney and coagulation function.

目的 观察百草枯中毒后大鼠血液中炎症因子的变化,以及大承气汤结合氢化可的松在百草枯中毒治疗中的作用。方法 选用广东省实验动物所的160只SD大鼠,雌雄各半。其中随机抽取 120 只大鼠给予百草枯溶液按18 mg/kg的剂量一次性腹腔注射给药,制造百草枯中毒大鼠模型其余 40只大鼠不作处理,作为正常组。再将模型组分为大承气汤联合氢化可的松组、氢化可的松组及盐水对照组,观察大鼠中毒情况,观察并分析给药后1 d、3 d以及5 d大鼠的肺组织以及血清炎症因子TNF-α、IL-2、IL-6等的变化情况。结果 正常对照组在中毒后1 d、3 d未见大鼠死亡,在5 d有1只动物死亡;模型组大鼠TNF-α、IL-2、IL-6水平高于对照组,差异有统计学意义(P<0.05);正常对照组大鼠各因子水平,随着中毒时间的延长逐渐增加,均有差异(P<0.05);大承气汤联合氢化可的松组给药后各时间点TNF-α、IL-2、IL-6降低,与氢化可的松组、盐水对照组均有差异(P<0.05)。结论 大鼠百草枯中毒后,肺组织发生纤维化改变,且TNF-α、IL-2、IL-6因子的水平升高,随着时间的推移,呈现上升趋势;大承气汤对百草枯中毒大鼠肺组织具有保护作用,可能调控各炎症因子作用,减缓病情进展来实现。
