Bumetanide protects focal cerebral ischemia-reperfusion injury in rat.
Bumetanide has been reported to attenuate ischemia-evoked cerebral edema. However, whether bumetanide can protect cerebral ischemia-reperfusion injury (IRI) in vivo is unclear. In the present study, we aim to determine whether intravenously injection bumetanide can attenuate cerebral IRI and if its protection effect might be related to the modification of cerebral NKCC1 and KCC2 protein expression. ⋯ These results suggest that bumetanide protects focal cerebral ischemia-reperfusion injury in rat, which might through the inhibition of NKCC1.

ReviewPrimary atypical teratoid/rhabdoid tumor of central nervous system in children: a clinicopathological analysis and review of literature in China.
Atypical teratoid/rhabdoid tumor (AT/RT) is a very rare and highly malignant embryonal tumor in the central nervous system (CNS). Five patients (4 girls and 1 boy) with AT/RT were treated in our hospital. The clinical histories, symptoms, neuroimaging aspects, therapies, histological and immunohistochemical findings and follow-up information were reviewed. ⋯ One case with no recurrence after 24 months may have benefited from radical excision and postoperative radiotherapy. The other 4 patients died 8, 4, 1 and 1-month respectively after operation without radiotherapy. The diagnosis of AT/RT depends on full sampling, careful observation the morphological characteristics and INI1 examination, even when the tumor are presented in uncommon sites, such as the spinal cord and the pineal region.

Review Case ReportsConcomitant occurrence of IgG4-related pleuritis and periaortitis: a case report with review of the literature.
IgG4-related sclerosing disease is an established disease entity with characteristic clinicopathological features. Some recent reports have demonstrated that this disease can occur in the respiratory system including the pleura. Herein, we describe the first documented case of concomitant occurrence of IgG4-related pleuritis and periaortitis. ⋯ Recently, the spectrum of IgG4-related sclerosing disease has expanded, and this disease can occur in the pleura, pericardium, and periaortic tissue. Although histopathological analysis of the pericardium and periaortic tissue was not performed in the present case, it was suspected that thickening of the pericardium and periaortic tissue was clinically due to IgG4-related sclerosing disease. Our clinicopathological analyses of IgG4-related pleuritis and pericarditis reveal that this disease can present as dyspnea and pleural and pericardial effusion as seen in the present case, therefore, it is important to recognize that IgG4-related sclerosing disease can occur in these organs for accurate diagnosis and treatment.

Review Case ReportsThe ambiguous boundary between EBV-related hemophagocytic lymphohistiocytosis and systemic EBV-driven T cell lymphoproliferative disorder.
Epstein Barr virus (EBV)-related hemophagocytic lymphohistiocytosis (EBV-HLH) is a form of acquired, infection-related HLH which typically represents a fulminant presentation of an acute EBV infection of CD8+ T cells with 30-50% mortality rate. Systemic EBV-positive lymphoproliferative disease of childhood (SE-LPD) is a rare T cell lymphoproliferative disorder predominantly arising in the setting of acute EBV infection, often presenting with HLH. Since both entities have been associated with clonal T cell populations, the discrimination between these diseases is often ambiguous. ⋯ Given the karyotypic findings in this sentinel case, a diagnosis of SE-LPD was rendered. The overlapping clinical and pathologic findings suggest that EBV-HLH and SE-LPD are a biologic continuum, rather than discrete entities. The most clinically useful marker of mortality was an abnormal karyotype rather than other standards of clonality assessment.

Randomized Controlled TrialEffects of sevoflurane and propofol on right ventricular function and pulmonary circulation in patients undergone esophagectomy.
Sevoflurane and propofol are both widely used in clinical anesthesia. The aim of this study is to compare the effects of sevoflurane and propofol on right ventricular function and pulmonary circulation in patients receiving esophagectomy. ⋯ Anesthesia with sevoflurane preserved better right ventricular function than propofol in patients receiving esophagectomy. However, propofol improved oxygenation and shunt fraction during one-lung ventilation compared with sevoflurane anesthesia. To have the best effect, anesthesiologists can choose the two anesthetics flexibly according to the monitoring results.
