Screening for carriers of spinal muscular atrophy (SMA) is necessary for effective clinical/prenatal diagnosis and genetic counseling. However, a population-based study of SMA prevalence in mainland China has not yet been conducted. In this study, the copy number of survival motor neuron (SMN) genes was determined in 1712 newborn cord blood samples(More)
PURPOSE The purpose of the study was to review a 10-year experience of operative procedures for rectovestibular fistula with normal anus (RVFNA) at one institution. MATERIALS AND METHODS From January 1999 to December 2008, 182 female patients of RVFNA were treated surgically in the Department of Surgery, Beijing Children's Hospital, Capital Medical(More)
AIM To evaluate liver stiffness measurement (LSM) using non-invasive transient elastography (Fibroscan) in comparison with liver biopsy for assessment of liver fibrosis in children with biliary atresia (BA). METHODS Thirty-one children with BA admitted to the Department of Pediatric Surgery of Beijing Children's Hospital from March 2012 to February 2013(More)
AIM To summarize the operative experience of the transanal approach in acquired rectovestibular fistula repair. METHODS Ninety-six cases of acquired rectovestibular fistula in young females were analyzed retrospectively. The etiology and operative procedure were discussed. Operative essential points were, the patient was laid in prone frog position, with(More)
Reliable detection of large deletions from cell-free fetal DNA (cffDNA) in maternal plasma is challenging, especially when both parents have the same deletion owing to a lack of specific markers for fetal genotyping. In order to evaluate the efficacy of a non-invasive prenatal diagnosis (NIPD) test to exclude α-thalassemia major that uses SNPs linked to the(More)
Splenogonadal fusion (SGF) is a rare congenital abnormality that affects children of both genders. Very few cases of SGF have been diagnosed preoperatively. In this study, the surgical findings and laparoscopic treatment of four children with SGF associated with intra-abdominal cryptorchidism are described. Laparoscopy was demonstrated to be the only(More)
AIM To determine the glycemic index (GI) and glycemic load (GL) values of Chinese traditional foods in Hong Kong. METHODS Fifteen healthy subjects (8 males and 7 females) volunteered to consume either glucose or one of 23 test foods after 10-14 h overnight fast. The blood glucose concentrations were analyzed immediately before, 15, 30, 45, 60, 90 and 120(More)
AIM To explore the pathogenesis of the rectovestibular disruption (RVD) defect and to recommend a successful repair, and prevention of it. METHODS Clinical records of 15 girls, age ranged from 3 to 15 (median, 7.5) years, with acquired rectovestibular fistula (RVF) mistreated before were retrospectively reviewed.

In tropical forests, trees compete not only with other trees, but also with lianas, which may limit tree growth and regeneration. Liana effects may depend on the availability of aboveand below-ground resources and differ between tree species. We conducted a shade house experiment to test the effect of light (4% and 35% full sun, using neutral-density(More)
Leaf physiology determines the carbon acquisition of the whole plant, but there can be considerable variation in physiology and carbon acquisition within individual leaves. Alocasia macrorrhiza (L.) Schott is an herbaceous species that can develop very large leaves of up to 1 m in length. However, little is known about the hydraulic and photosynthetic(More)
