Chinese guidelines for the assessment and provision of nutrition support therapy in critically ill children.

Background: This document represents the first evidence-based guidelines to describe best practices in nutrition therapy in critically ill children (> 1 month and < 18 years), who are expected to require a length of stay more than 2 or 3 days in a Pediatric Intensive Care Unit admitting medical patients domain.

Methods: A total of 25,673 articles were scanned for relevance. After careful review, 88 studies appeared to answer the pre-identified questions for the guidelines.

[The establishment of digital model about sagittal split ramus osteotomy and stability analysis of 3 different fixation methods].

Purpose: To establish the digital model about sagittal split ramus osteotomy and discuss the stress and displacement of 3 different fixation methods.

Methods: Three-dimensional reconstruction software Mimics and Geomagic were used to establish the three-dimensional entity model of mandible, and simulated sagittal split ramus osteotomy and fixation. Three-dimensional finite element model was established by mesh generation through ANSYS.

Objective: To explore the clinical features of types 3 and 7 adenovirus pneumonia in children and compare the difference between two types.

Methods: A total of 47 patients with adenovirus pneumonia at our hospital from January 2009 to June 2011 were reviewed. According to the serological types, they were divided into two groups: type 3 (n = 19) and type 7 (n = 28).

[Application of fenestration and suction drainage for treatment of large odontogenic mandibular cystic lesions].

Objective: To evaluate the effect of fenestration and suction drainage in the treatment of large odontogenic mandibular cystic lesions.

Methods: From 2005 to 2009, 24 cases of large odontogenic mandibular cystic lesions were treated with fenestration and suction drainage. The clinical symptoms and radiographical findings were evaluated before the operation and at 1 month and 6 months after suction drainage.

[Acute kidney injury in critically ill children infected with influenza A virus (H1N1) and enterovirus 71].

Objective: To analyze the clinical characteristics of acute kidney injury (AKI) in critically ill childhood patients with influenza A virus (H1N1) and enterovirus 71 (EV71), and to study the significance of the serum creatinine and urine output in diagnosis of AKI.

Method: The clinical data of AKI in critically ill children admitted to intensive care units (ICUs) with confirmed influenza A (H1N1) or enterovirus 71 infection (EV71 group) from Oct. 2009 to Oct.

[Analysis of clinical manifestations of hospitalized children infected with seasonal influenza A virus and 2009 novel influenza A (H1N1) virus in Beijing].

Objective: The novel influenza A (H1N1) virus firstly detected in April 2009 in Mexico rapidly spread to many countries including the United States and Canada where humans were infected with the H1N1 virus and deaths were reported. The pandemic virus strain had never been detected in specimen of human beings and swine. It was so highly contagious and widely spread that threatened life of humans globally.

[Chest radiographic findings in children with 2009 influenza A (H1N1) virus infection].

Objective: To evaluate chest radiographic findings of children with 2009 influenza (H1N1) virus infection.

Method: Data of 235 patients who had microbiologically confirmed H1N1 infection and available chest radiograph obtained between May 1(st) 2009 and Jan. 31(st) 2010 were retrospectively analyzed.

[Identification and typing of adenoviruses from pediatric patients with acute respiratory infections in Beijing from 2003 to 2008].

Objective: Adenovirus (ADV) is one of the most common causes of acute respiratory infections in infants and children. The objective of this study was to investigate the prevalence of adenovirus infection among pediatric patients with acute respiratory infections in Beijing and the types of the adenoviruses circulating in Beijing on the molecular bases.

Method: Clinical specimens including throat swabs from outpatients and nasopharyngeal aspirates from hospitalized patients were collected from patients with acute respiratory infections in a consecutive period of 6 years from Jan 2003 to Dec 2008.

[Pectoralis major myocutaneous flap for repairing large tissue defects following oral cancer surgery].

Objective: To investigate the method for reconstruction of large tissue defects following surgical resection of advanced oral cancer using pectoralis major myocutaneous flap.

Methods: From 2005 to 2009, 40 patients with advanced oral cancer received extensive surgical resection of oral cancer, and the intraoral defects were reconstructed using pectoralis major myocutaneous flaps.

Results: All the flaps survived except one flap with partial necrosis.

[Evaluation of forest ecosystem services value in Liaoning Province].

Based on the long-term located observation of forest ecosystem, and by using the 2006 forest resources inventory data of Liaoning Province and the forest industry standard of the People's Republic of China( LY/T 1721-2008, specification for assessment of forest ecosystem services in China), an evaluation was made on the material quantity and services value of main forest ecosystems in fourteen cities of Liaoning Province. In this province, the forest ecosystem services value supplied by water storage, soil conservation, C fixation, O2 release, nutrients accumulation, environment purification, biodiversity conservation, and forest recreation in 2006 was 2591.72 x 10(8) yuan, which was 8.

[Study on the association of hand, foot and mouth disease and enterovirus 71/CA16 among children in Beijing, 2007].

Objective: To reveal the etiological agent of hand, foot and mouth disease in children in Beijing.

Methods: Throat swabs were collected from 6 infants and young children with hand, foot and mouth disease who visited the affiliated Children's Hospital from May to June 2007. Aspirated fluid from tracheal intubatton, serum and cerebral spinal fluid (CSF) were collected from a 9 years old girl (No.

[The use of balloon catheter in surgical treatment of renal neoplasm with inferior vena cava thrombus].

Objective: To improve the treatment of renal neoplasm with tumor thrombus in the inferior vena cava.

Methods: From May 2005 to May 2006, 9 cases of renal neoplasm with tumor thrombus were treated with balloon catheters to block inferior vena cava under the level of liver vena during the operations. Among the patients, 6 were male and 3 were female.

[Necessity and safety of conversion from mycophenolate mofetil to AzA thioprine after renal transplantation].

Objective: To investigate the necessity and safety of conversion from mycophenolate mofetil (MMF) to Azathioprine (AzA) in stable renal transplant patients.

Methods: In a randomised open clinical trial, A total of 87 low-risk renal allograft recipients on triple immunosuppressive therapy (prednisone/MMF/cyclosporine) 6 months after transplantation was randomised into two groups: converted (switching MMF to AzA treatment 6 months after transplantation, n = 42) and control (continued MMF treatment, n = 45). Renal function, acute rejection episodes, side effects and related complications were analysed in each group.
