Diagnostic value of neuronal pentraxin II methylation in patients with pancreatic cancer: Meta-analysis.

Background: Pancreatic cancer (PC) is a devasting disease of which mortality almost parallels its incidence. PC tissue may express aberrantly methylated neuronal pentraxin II (NPTX2), but it is unclear what the consequences of this are.

Methods: We systematically searched PubMed, Web of Science, the Chinese National Knowledge Infrastructure (CNKI), from inception to July 15, 2020, to identify if the detection of methylated NPTX2 have sufficient sensitivity and specificity to identify PC from other benign pancreatic diseases.

The epidemiology of paediatric Mycoplasma pneumoniae pneumonia in North China: 2006 to 2016.

Paediatric Mycoplasma pneumoniae pneumonia (MPP) is a major cause of community-acquired pneumonia in China. Data on epidemiology of paediatric MPP from China are little known. This study retrospectively collected data from June 2006 to June 2016 in Beijing Children's Hospital, Capital Medical University of North China and aims to explore the epidemiological features of paediatric MPP and severe MPP (SMPP) in North China during the past 10 years.

Clinical and genetic characteristics of Chinese pediatric patients with chronic granulomatous disease.

Background: Chronic granulomatous disease (CGD) is a rare disease in China, and very little large-scale studies have been conducted to date. We aimed to investigate the clinical and genetic features of CGD in Chinese pediatric patients.

Methods: Pediatric patients with CGD from Beijing Children's Hospital, Capital Medical University, China, were enrolled from January 2006 to December 2016.

[The value of flow cytometry for the differential diagnosis between refractory cytopenia with multiple dysplasia and aplastic anemia].

Objective: To evaluate the value of flow cytometry (FCM) for the differential diagnosis between myelodysplasia (MDS) subtype refractory cytopenia with multiple dysplasia (RCMD) and aplastic anemia (AA).

Methods: The flow cytometric data of bone marrow samples from 168 cases of RCMD and 77 cases of AA were analyzed retrospectively in blind, and its results were compared with gold standard to evaluate its diagnosis values.

Results: The specificity of abnormal of single immunophenotype in the surface of granulocytes and myeloblasts was high (range 75.

[Clinical characteristics of primary ciliary dyskinesia in children].

Objective: Although primary ciliary dyskinesia (PCD) is a group of inherited diseases, accurate diagnosis and appropriate clinical care to prevent and treat the complications could maintain patients' quality of life and normal life span. The diagnosis of PCD may often be delayed because it is frequently misdiagnosed as bronchitis, sinusitis and otitis. This study aimed to analyze and summarize the clinical features of PCD and explore diagnostic and differential diagnostic procedures in children.

[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.
