Background: Geleophysic dysplasia (GD) presents the characterized clinical manifestations of acromelic dysplasia, including extremely short stature, short limbs, small hands and feet, stubby fingers and toes, joint stiffness and others. It is clinically distinct from the other acromelic dysplasia in terms of symptoms such as cardiac valvular abnormalities, progressive hepatomegaly and tracheal stenosis.

Case Summary: We report on a Chinese 9-year-old girl with GD with the c.

Objectives: The treatment of acute herpangina is inconsistent. We aim to evaluate the effectiveness and safety of interferon α-2b spray versus Ribavirin for this disease.

Methods: A randomized, controlled trial was conducted in eight hospitals in China between 2016 and 2018.

Diffuse alveolar hemorrhage with histopathologic manifestations of pulmonary capillaritis: Three case reports.

Background: Diffuse alveolar hemorrhage (DAH) is a multicause pulmonary capillary hemorrhage or pulmonary vascular small vessel injury (mainly capillaries, including arteries and veins), causing pulmonary microcirculation blood to accumulate in the alveolar space. DAH is classified by the histological absence or presence of pulmonary capillaritis (PC) and is rarely reported in the literature.

Case Summary: This is a report of three girls aged 6-11 years with DAH and PC.

Background: Chronic cough is a common symptom in children and protracted bacterial bronchitis (PBB) is one of the causes of chronic cough. However, the understanding of this disease remains limited. The present study aims to update PBB in children.

Diagnosis and treatment of herpangina: Chinese expert consensus.

Background: Herpangina is a common infectious disease in childhood caused by an enterovirus. This consensus is aiming to standardize and improve herpangina prevention and clinical diagnosis.

Methods: The Subspecialty Group of Infectious Diseases, the Society of Pediatric, Chinese Medical Association and Nation Medical Quality Control Center for Infectious Diseases gathered 20 experts to develop the consensus, who are specialized in diagnosis and treatment of herpangina.

[Advances in application of Jurkat cell model in research on infectious diseases].

Infectious diseases can be caused by multiple pathogens, which can produce specific immune response in human body. The immune response produced by T cells is cellular immunity, which plays an important role in the anti-infection process of human body, and can participate in immunological protection and cause immunopathology. The outcome of various infectious diseases is closely related to cellular immune function, especially the function of T cells.

[Role of programmed death-1 in viral infectious diseases].

The research on the immunoregulatory effect of programmed death-1 (PD-1) in infectious diseases mainly focuses on chronic viral infection, but there are few studies on acute viral infection. In chronic viral infection, PD-1 is highly expressed on the surface of CD8 T cells, which is a sign of CD8 T cell depletion. Recent studies have shown that in chronic viral infection, PD-1 is also highly expressed on the surface of regulatory T cells and binds to programmed death-ligand 1 (PD-L1) on the surface of exhausted CD8 T cells, resulting in a stronger inhibitory effect on CD8 T cell immunity.

Clinical features for 89 deaths of hand, foot and mouth disease in Guangxi, China, 2014.

Objectives: The aim of this study is to summarize the risk factors of severe Hand, foot and mouth disease (HFMD) and explore the clinical characteristics of pulmonary edema (PE) and non-PE in the deceased patients with HFMD.

Methods: We identified 89 HFMD deaths which were separated into the PE group or non-PE group. Next, patients were divided based on their initial admission to hospitals as stage 1, 2, 3, or 4; at this point, their clinical manifestations were compared.

[Expression and role of Tc17 cells in mice with neutrophilic asthma].

Objective: To determine the proportion of Tc17 cells in the lungs of mice with neutrophilic(NEU) asthma, and to investigate the role of Tc17 cells in the pathogenesis of NEU asthma.

Methods: Thirty-two C57/B6 mice of clean grade were randomly divided into two groups: NEU asthma and control. The mice in the NEU asthma group were sensitized by airway instillation of ovalbumin (OVA) and lipopolysaccharide (LPS), and challenged with an aerosol of OVA, while those in the control group were sensitized and challenged with normal saline.

Addressing parental smoking in pediatric settings of chinese hospitals: a qualitative study of parents.

This study explored factors associated with SHS exposure from parental smoking in Chinese families and assessed nature of antismoking discussions parents had with their children's pediatricians and how pediatricians might best engage with parents in an effort to reduce children's exposure to SHS. Six focus group discussions (FGDs) were conducted among 33 Chinese parents attending six major hospitals in Guangxi province, China. Most participants (32/33) had family members who smoke, and only 21% had strict restriction on smoking at home.

Leukotriene receptor antagonists for small-airway abnormalities in asthmatics: a systematic review and meta-analysis.

Background: Airway inflammation that occurs in asthma is mainly distributed in the small airways. Leukotriene receptor antagonists (LTRAs) are systemically active drugs that may act on the small airways.

Objectives: The aim of our study was to assess the efficacy of LTRAs for small-airway abnormalities in asthmatics.

[Pulmonary surfactant associated gene variants in mixed ethnic population of Han and Zhuang].

Objective: To explore the prevalence of pulmonary surfactant associated pathway genes functional variants in Chinese population.

Method: Using a cohort of 258 mixed ethnic population of Han and Zhuang, we pooled DNA samples from 146 term male infants and 112 term female infants and then used an Ill umina next generation sequencing platform to perform the complete exonic resequencing in 6 target genes:surfactant protein-B (SFTPB), surfactant protein-C (SFTPC), ATP-binding cassette transporter A3 (ABCA3), lysophospholipid acyltransferase 1 (LPCAT1), choline phosphotransferase 1 (CHPT1), phosphate cytidylyltransferase 1, choline, beta (PCYT1B). Collapsing methods was used to determine the functional allele frequency.

[Causes of chronic cough in children: an analysis of 111 cases].

Objective: To investigate the causes of chronic cough in children.

Methods: A prospective cohort study was performed on 111 children with chronic cough who were referred to the First Affiliated Hospital of Guangxi Medical University between December 2008 and January 2011. The causes of chronic cough were investigted.

[Primary immunodeficiency diseases in children: clinical analysis of 35 cases].

Objective: To summarize clinical features of primary immunodeficiency diseases (PID) in children.

Methods: The clinical data of 35 children with PID from September 2005 to December 2008 were studied retrospectively, including illness history, birth history, family history, clinical manifestations, laboratory findings, diagnosis, treatment and outcome.

Results: Of the 35 cases of PID, 6 cases were confirmed with combined T- and B-cell immunodeficiency, 4 cases with X-linked agammaglobulinaemia, 22 cases with selective IgG subclass deficiency, 1 case with common variable immunodeficiency and 2 cases with chronic granulomatous disease.

[Airway neutrophils apoptosis in children with severe asthma].

Objective: To investigate the changes of neutrophils in airway inflammation in children with severe asthma.

Method: Children with mild to moderate asthma (n=23), severe asthma (n=16) and healthy control subjects (n=16) underwent lung function tests and sputum induction. The sputum specimens were assayed for cellular differential count, the supernatant and peripheral blood were assayed for the concentrations of IL-8 by "sandwich" enzyme linked immunosorbent assay (ELISA).

[Eosinophils apoptosis in asthmatic children].

Unlabelled: Prominent eosinophil airway inflammation is important in the pathogenesis of asthma. There is increasing evidence that the disorder of eosinophil apoptosis contributes to the mechanism. But most of the studies have been done in vitro or on animal models, very few were done among the adult asthmatics in vivo.
