OBJECTIVE Convincing evidence suggests a link between increased risk of nonsyndromic cleft lip with or without cleft palate (NSCL/P) and low intake of folic acid by the mother during pregnancy. The present study was designed to explore if genetic variation in the betaine-homocysteine methyltransferase (BHMT) gene contributes to NSCL/P. METHODS DNA was(More)
The toxicity of sodium benzoate to trypsin was investigated by fluorescence spectroscopy, synchronous fluorescence spectroscopy, UV-visible absorption spectroscopy and circular dichroism (CD) spectroscopy under mimic physiological conditions. Sodium benzoate could unfold trypsin by decreasing the β-sheet structure, which leads to more exposure of internal(More)
An extremely rare patient of congenital midline sinus of the upper lip in a 2-year-old boy is presented. The sinus was located on the midline of the philtrum just below the base of the columella. Surgical removal of the sinus was performed via an extra- and inraoral approach. Histopathological examination of the resected sinus revealed it to be lined by(More)
OBJECTIVE To explore the prevalence of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) and the risk factors among opiate drug users in Beijing. METHODS The opiate drug users enrolled in methadone maintenance treatment clinics of Beijing from 30 November 2004 to 31 March 2008 were investigated. The blood samples were collected and tested for(More)
BACKGROUND In recent years, amphetamine-type stimulants (ATS) have increased dramatically in East-south Asia, especially in China. Most ATS users suffered from psychosis comorbidity, and depression is the main syndrome in ATS users. METHODOLOGY A cross-sectional study of depressive symptoms and associated factors among ATS users was conducted in(More)
Ankyloblepharon-ectodermal defects-cleft lip/palate (AEC) syndrome, also known as Hay-Wells syndrome, is an autosomal genetic disease with the main features of ankyloblepharon filiforme adnatum, ectodermal defects, and cleft lip/palate. The authors report a patient with 17 months old girl with AEC syndrome having ankyloblepharon, cleft and palate, and(More)
AIM To survey and assess the drug dependence and abuse potential liability of buprenorphine among opiate abusers. METHODS Subjects of opiate dependence with history of buprenorphine use for 3 d at least were surveyed by interview. Physical dependence of buprenorphine was assessed using 30 items opiate withdrawal scale (OWS), which composed of 30(More)
The Tessier number 3 cleft is rare. In this paper, we report two extremely rare cases of simultaneous Tessier number 3 cleft, contralateral cleft lip, and signs of amniotic band syndrome. In the two cases, we confirmed that amniotic bands were the probable cause of the Tessier number 3 cleft, where swallowed fibrous strands of amniotic bands entangle a(More)
With the constant progress of laser physics, medical laser technology has been widely applied in clinical practices and basic researches. In this article, we reviewed the relevant articles on the laser applications in dental implantology and concluded that lasers provides promising solutions in the treatment technology of dental implants and in the(More)
The isolated naso-ocular cleft is rare. In this article, the authors report an extremely rare case of unilateral isolated naso-ocular cleft. And a new rotation-advancement technique was used in repair. Result was satisfied, especially the esthetical scar location. But if an upper lid flap was performed simultaneously, the result should be better.
