A case of large pulmonary embolism in trunk and branches with main manifestation of syncope, vomiting and shock / 中华危重病急救医学

Pulmonary embolism (PE) refers to the endogenous or exogenous emboli blocking pulmonary trunk or branches, causing clinical and pathophysiological syndrome of pulmonary circulation disorder, the incidence rate is high. Sometimes PE patients were lack of specific symptoms and signs, or without any symptoms, which often result in misdiagnosis, un-timely diagnosis, and the delay of treatment. A PE case with syncope, vomiting and shock, which was proved to be pulmonary artery trunk and branch wide embolism later, was presented so as to improve the understanding of the disease.

Epidemiology of traumatic cervical spinal cord injury in ICU / 中华急诊医学杂志

Objective To investigate the epidemiological characteristics of traumatic cervical spinal cord injury (TCSCI) in ICU.Method The data of patients with TCSCI admitted from October 2010 to March 2016 in the intensive care unit were retrospectively studied.The general epidemiological data included:gender,age,marital status,occupation,cause of injury,injury severity,injured segment (ASIA grade),and complications were collected.Results There were 109 patients identified to have TCSCI with mean age of 53.72 ± 14.86 years (25.69％ patients in the range of 60-69 years old).The male to female ratio was 9:1,and the most were married.The majority of individuals were retired (30.27％),and the main causes of injury were traffic accidents and tumble.The C5 segment of the spine was the most vulnerable to be injured,and then the C4 segment was the nest in turn.There were up to 30.28％ patients suffered from multiple injuries,and 26.61％ patients also had a craniocerebral injury.Bedsore and respiratory system complications were the two leading complications,and 83 patients suffered from at least one system dysfunction with respiratory dysfunction accounted for 98.79％ and circulatory dysfunction accounted for 65.06％.Fifty-one patients presented more than two system dysfunctions (46.79％).Twenty patients (18.35％) died.Conclusion Patients with TCSCI in ICU presented specially characteristic features.Traffic accidents were the main cause of TCSCI,and fall accidents were one of the main causes in the elderly.The mortality of TCSCI was high,especially in males.The complication rate was relatively high and the most common complications were water and electrolyte disturbance and respiratory dysfunction.Multiple organ dysfunction incidences might be associated with the ASIA grades.

CD4 + CD25 + T regulatory cells in predicting the prognoses of patients with sepsis / 中华急诊医学杂志

Objective We aimed to evaluate the role of CD4 + CD25 + T regulatory cells in predicting the prognoses of patients with sepsis.Methods Patients with sepsis in Shanghai Changzheng Hospital from December 2013 to April 2014 were identified and grouped into survival group (SG,n =19) and death group (DG,n =9) in accordance with their clinical outcomes.CD4 + CD25 +T regulatory cell ratio,C-replication protein,bilirubin,procalcitonin,and coagulation function were tested on the 1st day and 7th day,and APACHE Ⅱ and SOFA were analyzed to assess the predictability of this group of cells.Results Twentyeight patients were identified,with a mean age of (60.36 ± 15.30) years,a mean APACHE Ⅱ score of (16.68±7.00),and a mean SOFA score of (7.18 ±3.78).Twelve (42.9％) of the individuals were accompanied with severe multiple trauma,and 10 (35.7％) were in septic shock,and 9 (32.2％) died of severe sepsis.The first day CD4 + CD25 + T regulatory cell ratios on the first day were 2.10％ (0.80,3.10)％ (SG) vs.1.80％ (1.15,3.65)％ (DG) (Z=-0.148,P=0.883),andonday7 were 0.90％ (0.30,2.80)％ (SG) vs.5.70％ (2.60,8.30)％ (DG) (Z=-2.905,P=0.004) presented significant predictability.Conclusions Dynamic monitoring of CD4 + CD25 + T regulatory cells could predict the prognoses of patients with sepsis and should be generalized in clinical emergency practice.
