Objective To investigate the regulatory effect of testosterone propionate injection combined with ulinastatin on immune imbalance in patients with sepsis.Methods A total of 88 patients with sepsis treated in our hospital from October 2019 to January 2020 were randomly divided into observation group and control group,with 44 cases each.The control group was treated with ulinastatin combined with routine treatment,while the observation group was treated with testosterone propionate injection additionally.The clinical efficacy difference between the two groups were compared after treating 1 week.The levels of inflammatory factors [interleukin-6 (IL-6),interleukin-10 (IL-10),interleukin-1 β (IL-1β)],testosterone (T),albumin (Alb),the severity of disease (APACHE II score) and the degree of organ failure (SOFA score) in the two groups were observed before and 1 week after treatment.The differences of adverse drug reactions between the two groups within 1 week of treatment were analyzed.Results The total effective rate of the observation group was higher than that of the control group (P＜0.05).IL-6 and IL-1β levels and APACHE II and SOFA scores decreased after treatment,while those of the observation group were lower than the control group (P＜0.05).The levels of IL-10,T and Alb in the two groups were increased,while those in the observation group were higher than the control group (P ＜ 0.05); the total incidence of adverse drug reactions in the two groups was not statistically significant (P>0.05).Conclusions Testosterone propionate injection combined with ulinastatin had good clinical efficacy in the treatment of sepsis,effectively improved the condition and prognosis,and had positive significance in the regulation of immune imbalance.

Objective To explore the effect of sequential organ failure assessment (SOFA) combined with soluble programmed death factor-1 (sPD-1) level on the prognosis of patients with sepsis. Methods A total of 86 patients with sepsis in our hospital from March 2019 to March 2021 were selected and divided into survival group (59 cases) and death group (27 cases) according to their prognosis (28-day outcome). The levels of sPD-1, inflammatory cytokines, SOFA and APACHEⅡ scores of two groups were recorded. The risk factors of 28-day mortality were analyzed. The prognostic values of SOFA+sPD-1 in patients with sepsis were analyzed by ROC curve. Results Age, C-reactive protein (CRP), procalcitonin (PCT) and sPD-1 levels and SOFA, APACHEⅡ scores of death group were higher than those of survival group (P＜0.05). By Logistic regression analysis, sPD-1 level, SOFA and APACHEⅡ scores were identified as independent predictors of 28-day death in patients with sepsis (P＜0.05). After combining prediction, the area under the ROC curve of SOFA+sPD-1 was the largest (0.862), and the sensitivity and specificity were 88.89% and 88.14% respectively. Conclusion In the prognosis evaluation of patients with sepsis, both sPD-1 level and SOFA score were independent predictors of 28-day mortality, and SOFA+sPD-1 was more effective in predicting the prognosis of patients with sepsis.

目的 通过对婴幼儿泌尿系感染并发脓毒症的临床特点、病原菌情况及相关因素的分析,探讨其早期诊断和及时治疗的措施。方法 选取83例我科收治的确诊泌尿系感染合并脓毒症的婴幼儿作为研究对象,回顾性分析其临床表现、实验室检查及治疗预后情况。结果 所选婴幼儿均确诊泌尿系感染合并脓毒症,以男性患儿多见,全身中毒症状重,6月以下多以严重脓毒症、脓毒性休克为首诊表现,尿路刺激症状不明显。有明显细菌感染生物标记物的改变。细菌学培养共检出细菌22株,大肠埃希菌占54.55% (12/22),对头孢吡肟较为敏感,对亚胺培南、美罗培南全部敏感;屎肠球菌占22.73%(5/22),对万古霉素、利奈唑胺、替考拉宁敏感。结论 在婴幼儿常见的感染部位中,泌尿系感染容易被忽略。而小于6月的患儿更易并发严重脓毒症、脓毒症休克等危重症。因此,以脓毒症为首诊表现的婴幼儿应特别警惕泌尿系感染,尽可能早期明确感染部位,防止漏诊。首诊1小时内给予广谱抗生素治疗,可降低婴幼儿脓毒症的病死率,改善患儿预后。

Objective By analyzing the clinical features, laboratory tests, pathogenic bacteria culture and the treatments of infants and toddlers with urinary tract infection UTI accompanied with sepsis, we aim to guide the further clinical treatments and prevention. Methods We selected 83 cases from January 1, 2014 to December 31, 2016 in our hospital as the research objects which were accepted the diagnosis and treatments of urinary tract infection complicated with sepsis. Its clinical manifestations, laboratory tests, bacteriology examination and treatment prognosis were retrospectively analyzed. Results Among the selected infants and toddlers diagnosed with urinary tract infection complicated with sepsis, male patients were more common. Symptoms of systemic poisoning were observed in the majority especially in the children aging under 6 months, with severe sepsis and septic shock as the first manifestation, while conventional symptoms were not obvious. Biological markers of bacterial infection were significantly changed. In bacterial culture, 22 strains of bacteria were detected, Escherichia coli accounted for 54.55% (12/22), were almost sensitive to cefepime, and all sensitive to imipenem and meropenem; Enterococcus following accounted for 22.73% (5/22), could be more sensitive to vancomycin, linezolid, teicoplanin. Conclusion Urinary tract infection is common in under 3 years old babies. Patients aging under 6 months are more likely to be complicated with severe sepsis and septic shock. Therefore, we should be especially vigilant of the UTI among the babies whose first manifestations appear to be sepsis only. It is important to find out the site of infection as early as possible, in order to prevent misdiagnosis. It is also critical to use broad-spectrum antimicrobial therapy within 1 hour when severe sepsis is diagnosed in order to reduce the mortality of sepsis in infants and improve the prognosis.
