目的 探讨脓毒症患者的病情预后与高密度脂蛋白（HDL）之间的关联性。 方法 2008年3月1日－2010年2月28日选择50例严重脓毒症患者（脓毒症组）和30例非脓毒症的健康人（对照组），比较两组急性生理学与慢性健康状况评分Ⅱ（APACHEⅡ）和HDL水平。 结果 脓毒症组的HDL水平为（1.10 ± 0.39）mmol/L，对照组HDL水平为（1.61 ± 0.42） mmol/L，两组差异有统计学意义（t=6.786，P=0.000）。多因素非条件logistic回归分析显示，HDL水平（OR=0.877，P=0.025）和APACHEⅡ评分（OR=15.556，P=0.009）是影响脓毒症患者患病程度的两个有效独立因素。 结论 脓毒症能够导致患者的脂代谢出现紊乱，HDL水平是评估脓毒症患病程度的较好指标。
ObjectiveTo explore the clinical diagnosis and treatment of Talaromyces marneffei (TM) infection by bone marrow examination, and to clarify the important role and significance of bone marrow smear and pathogenic examination.MethodsRetrospective analysis was conducted on a case of disseminated TM infection that was clearly diagnosed through bone marrow related examination. Literature review of TM infection was conducted by retrieving relevant case reports at home and abroad from 1990 to 2018.ResultsThe patient was a 23-year-old man with recurrent cough and onset of fever, superficial lymph node enlargement in multiple parts of the body, no abnormal chest CT sign, and poor efficacy in anti-infection treatment. The patient developed progressive abdominal pain, accompanied by systemic papulosis, decreased consciousness, and progressive decline of blood cells. The patient underwent bone marrow puncture surgery in our hospital, and developed circulatory and respiratory failure half an hour after surgery. TM was confirmed bybone marrow smear and pathogenic culture. In the literature review, 2 855 cases of TM infection were retrieved, among which the majority of cases were confirmed through blood and bone marrow related examination. The positive rate of bone marrow culture was significantly higher than that of blood culture (72.4% and 66.8%, respectively, P=0.007). Compared with bone marrow culture, the misdiagnosis and missed diagnosis rate of bone marrow smear microscopy was 27.6%. Patients diagnosed with TM infection by bone marrow examination had the highest HIV positive rate (95.7%).ConclusionsThe examination of bone marrow cells and the culture are of great clinical significance for the diagnosis of TM infection. TM infection should be identified in patients suspected of HIV positive with fever, lymph node enlargement and abnormal blood routine.
