lipopolysaccharide (Pg-LPS) influences adipocytes injuries through triggering XBP1 and activating mitochondria-mediated apoptosis.

Obesity is an important public-health problem worldwide. This study aimed to determine effects of porphyromonas gingivalis lipopolysaccharide (Pg-LPS) on adipocytes injuries and explore associated mechanisms. Adipocytes were isolated from SD rats.

[Clinical analysis of children with lymphoma complicated with severe pneumonia due to novel influenza A (H1N1) virus infection].

Objective: To study the clinical features and treatment of severe pneumonia due to novel influenza A (H1N1) virus in children with lymphoma during chemotherapy.

Method: The clinical manifestations, radiologic features, reasons of misdiagnosis, experiences in treatment and prognosis of 4 children with lymphoma complicated with pneumonia due to novel influenza A (H1N1) virus during chemotherapy were analyzed retrospectively.

[Imaging and quantitative measurement of brain extracellular space using MRI Gd-DTPA tracer method].

Objective: To observe the diffusion of Gd-DTPA in brain extracellular space (ECS) by magnetic resonance imaging(MRI) and investigate the feasibility of ECS measurement by using MRI tracer method in vivo.

Methods: 2 microL Gd-DTPA was introduced into ECS by caudate nucleus according to stereotaxic atlas in 8 Sprague Dawley(SD) rats (male, 280-320 g). The MRI scans were performed at 1 h, 3 h, 6 h, 9 h and 12 h respectively after administration.

[Diagnosis and treatment of invasive pulmonary aspergillosis in 21 children with non-hematologic diseases].

Objective: To explore diagnosis and treatments of invasive pulmonary aspergillosis (IPA) in children with non-hematologic diseases.

Method: Twenty one patients without hematological malignancy were diagnosed with proven or possible IPA from July 2002 to June 2008. The risk factors, clinical manifestations, chest radiographic findings, microbiological and histopathological evidence, diagnostic procedures, treatment and prognosis were retrospectively reviewed.

[Recurrent massive bloody pleural effusion caused by pancreatic pleural fistula in a case].

Objective: To introduce the early clinical features and the main points of diagnosis and treatment of children with pancreatic pleural fistula presenting massive bloody pleural effusion.

Method: The clinical data of symptoms, signs, laboratory examination, diagnosis and treatment methods of pancreatic pleural fistula in a child are presented.

Result: A 4-year-old boy presented with one month history of intermittent fever, cough, chest tightness and chest pain.

[Clinical studies of children with bronchiolitis obliterans].

Objective: Bronchiolitis obliterans (BO) is a chronic airflow obstruction syndrome associated with inflammatory lesions of the small airways. The etiology, pathogenesis, effective treatment and prognosis of this disorder remain uncertain by now. There has been no large scale clinical research on BO in China.

[Clinical analysis of pediatric SARS cases in Beijing].

Objective: To study clinical characteristics of pediatric SARS cases in Beijing.

Methods: Eighteen pediatric cases with SARS diagnosed on admission were analyzed. The cases were admitted to Beijing Children's Hospital and Ditan Hospital (pediatric ward) from April 8 to May 12.

[Clinical feature of four cases with bronchiolitis obliterans].

Objective: To recognize the clinical features of the bronchiolitis obliterans.

Method: Clinical manifestation, chest X-ray, computed tomography (CT) and pulmonary function of 4 cases with bronchiolitis obliterans were retrospectively analyzed.

Result: Two cases were after Stevens-Johnson syndrome (SJS), the other 2 were after severe pneumonia, including one suffered from adenovirus pneumonia.
