[Association of vitamin D concentrations with juvenile idiopathic arthritis].

Objective: 25-Hydroxyvitamin D3 [25(OH)D3] is the main product of vitamin D and can reflect the absolute concentration of active vitamin D in the body. This study examined serum 25(OH)D3 levels in children with juvenile idiopathic arthritis (JIA) in order to explore the association of vitamin D concentrations with the pathogenesis and disease activity of JIA.

Methods: Serum samples were collected from 53 children confirmed as having JIA between January 2013 and March 2014, as well as 106 healthy children (control group) who underwent physical examination in the same period.

Epidemiology and burden of rotavirus infection among children in Hangzhou, China.

Background: Rotavirus is the most common cause of acute diarrhea in children younger than 5 years worldwide. However, few data have been collected on children with rotavirus diarrhea basing on outpatient department surveillance.

Objectives: To define the epidemiology of rotavirus diarrhea and to investigate the burden associated with diarrhea and rotavirus infection in Hangzhou, China.

[Analysis of VP7 serotype of rotavirus in infantile diarrhea in Hangzhou area from 2001 to 2003].

Objective: To investigate molecular epidemiologic features of rotavirus (RV) infection in infantile diarrhea in Hangzhou area.

Methods: Stool specimens of 683 infants with suspected acute viral enteritis in the autumn and winter of 2001 - 2003 were collected. RV (group A) was detected by using latex agglutination test (LAT).

[Rapid diagnosis of neonatal sepsis by 16SrRNA genes PCR amplification and genechip hybridization].

Objective: To explore a method for rapid diagnosis of sepsis in newborn infants.

Methods: (1) The primers and oligonucleotide probes were designed and synthesized based on the sequences of bacterial 16SrRNA gene. The gene chip was prepared through the probes printed onto special glass slides.
