Advances in pathogenic mechanisms of Angiostrongylus cantonensis infection / 中国血吸虫病防治杂志

Angiostrongylosis, a food-borne parasitic disease, is caused by the migration of larvae of Angiostrongylus cantonensis to the host’s central nervous system after it is infected. It is a serious disease with eosinophilic encephalitis and meningoencephalitis as the main clinical manifestations. Understanding of its pathogenic mechanism is important for the prevention and treatment of angiostrongylosis. This paper reviews the mechanism of eosinophilic meningitis and meningoencephalitis caused by A. cantonensis infection.

Research progress on gastrointestinal hemorrhage after cardiac surgery / 中国胸心血管外科临床杂志

@#Although the incidence of gastrointestinal hemorrhage after cardiac surgery is low, the mortality rate is high. Early detection and diagnosis of gastrointestinal hemorrhage are difficult. The high risk phases including preoperation, intraoperation and postoperation. Preoperative high risk comorbidities include gastrointestinal ulcer, hypertension, coronary heart disease and chronic renal failure. Intraoperative high risk factors include decreased gastrointestinal blood perfusion due to cardiopulmonary bypass, inflammatory factors releasing, coagulation disorders, and thrombosis. Postoperative high risk factors include hypotension, low cardiac output, prolonged mechanical ventilation, etc. This article retrospectively summarized high-risk factors and pathogenesis of gastrointestinal hemorrhage after cardiac surgery, in order to improve prevention and treatment of gastrointestinal hemorrhage.
