目的 探讨H2受体拮抗剂和质子泵抑制剂（PPI）缓解急性胃黏膜损伤的时效性研究。 方法 对2008年1月－2010年1月在急诊科就诊的98例急性乙醇中毒后胃黏膜损伤患者，随机分为对照组50例，治疗组48例。常规给予休息、保暖，补液，维持水、电解质、酸碱平衡，维持循环功能等治疗基础上，对照组给予H2受体拮抗剂治疗，治疗组给予PPI治疗。通过观察急性胃黏膜损伤患者上消化道症状及体征，记录不同饮酒及饮酒量，并根据患者就诊时间及不同饮酒组治疗后上消化道症状完全缓解时间进行比较。 结果 治疗组上消化道症状缓解所需时间与对照组比较差异有统计学意义（P＜0.001），不同饮酒组上消化道症状缓解时间上差异有统计学意义（P=0.000）。 结论 PPI在缓解急性乙醇中毒所致胃黏膜损伤的时效上更明显，具有临床价值。
During the prevention and control of coronavirus disease 2019, West China Hospital of Sichuan University urgently set up 4 medical tents to conduct centralized screening of fever patients, effectively avoiding cross-infection, and at the same time alleviating the pressure on the Department of Emergency Medicine and improving the efficiency of medical treatment for patients with fever. Later, in order to actively respond to China’s severe acute respiratory syndrome coronavirus 2 nucleic acid detection policy, 5 tents were adjusted to carry out the severe acute respiratory syndrome coronavirus 2 nucleic acid detection. This article introduces the function setting, personnel arrangement and protective measures of medical tents in West China Hospital of Sichuan University during the prevention and control of coronavirus disease 2019. It aims to share the experience of urgently setting up medical tents in the prevention and control of coronavirus disease 2019, with a view to provide a reference for the construction of medical tents in other medical institutions.
目的 探讨血清降钙素原（PCT）、C反应蛋白（CRP）与急性生理及慢性健康评分标准Ⅱ（APACHE Ⅱ）评分在转诊肺炎合并脓毒症患者诊断中的相关性，以寻找更为简洁、快速判断其病情严重程度的指标。 方法 2009年1月－2010年12月，选取178例转诊肺炎合并脓毒症患者并进行脓毒症分级，对其进行血清PCT和CRP测定，并与APACHE Ⅱ评分及预后进行相关性分析。 结果 严重脓毒症组及脓毒性休克组患者血清PCT、CRP水平与APACHE Ⅱ评分较全身炎症反应综合征组及脓毒症组高（P＜0.05）；30 d内死亡的患者其血清PCT、CRP水平及APACHEⅡ评分较存活组明显增高（P＜0.05）；转诊肺炎合并脓毒症患者血清PCT与APACHE Ⅱ评分呈正相关（r=0.683，P=0.023），与血清CRP水平呈较弱的正相关（r=0.272，P=0.037）。 结论 对转院肺炎合并脓毒症患者进行血清PCT和CRP测定，对病情评估具有一定临床价值，特别是PCT可作为对转诊肺炎合并脓毒症患者病情程度判断的重要指标，为早期干预及治疗提供依据，值得临床推广应用。
Objective To develop a novel prediction model based on cerebrospinal fluid (CSF) lactate for early identification of high-risk central nervous system (CNS) infection patients in the emergency setting. Methods Patients diagnosed with CNS infections admitted to the Department of Emergency Medicine of West China Hospital, Sichuan University between January 1, 2020 and December 31, 2023 were retrospectively selected. Patients were classified into a survival group and a death group according to their 28-day survival status, and clinical characteristics were compared between groups. Univariate and multivariate logistic regression analyses were performed to identify independent predictors of 28-day mortality, which were subsequently used to construct a nomogram. Results A total of 173 patients were included, comprising 135 in the survival group and 38 in the death group. Multivariate analysis identified the Acute Physiology and Chronic Health Evaluation Ⅳ (APACHE Ⅳ) score [odds ratio (OR)=1.027, 95% confidence interval (CI) (1.002, 1.055), P=0.034], CSF lactate [OR=1.147, 95%CI (1.025, 1.286), P=0.018], and interleukin-6 [OR=1.002, 95%CI (1.001, 1.004), P=0.002] as independent predictors of 28-day mortality. The integrated model combining APACHE Ⅳ score, CSF lactate, and interleukin-6, demonstrated superior predictive performance compared with the APACHE Ⅳ score alone (P=0.020), and showed good calibration (Hosmer-Lemeshow P=0.50). Conclusions This tool may provide a useful instrument for emergency physicians to assess the 28-day mortality risk in patients with CNS infections, potentially facilitating early and targeted interventions for high-risk individuals. However, as the findings of this study are derived from a single-center retrospective dataset, the clinical applicability of this model requires further external validation through large-scale, prospective, multicenter studies to evaluate its generalizability.
