Objective To determine the measurement of two-dimensional shape parameters of nose and to eatablish the symmetric standard of nasal morphology.Methods Twenty-three frontal view photo-graphs of children aged 5 years with unilateral cleft lip were randomly selected,in which all children in the photographs were at an elevation of 45 degrees.Using Osiris and Image J for image intensification and di-vision,the area of nostril and nasal form were measured and artificial geometry figure were determined.Results The area of nostril affected was significantly smaller than those unaffected(P

Objective We discussed the nursing method for patients with diabetes mellitus undergoing continuous glucose monitoring in order to increase professional nursing level. Methods We summarized the general nursing points of continuous glucose monitoring system (CGMS) through applying effective nursing in 46 patients with diabetes mellitus undergoing continuous glucose monitoring. Results All 46 patients undergoing continuous glucose monitoring finished the examination and acquired satisfying glucose diagram, which supplied scientific reference for the diagnosis and treatment of diabetes mellitus. Conclusions Correct operation of CGMS, strengthening of clinical observation and psychological nursing and health education for patients proved to be the pivotal process for successful continuous glucose monitoring.

Background: Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disorder mainly caused by homozygous deletions that include exon 7 of the survival motor neuron 1 (SMN1) gene. A nearby paralog gene, SMN2, obstructs the specific detection of SMN1. We optimized a duplexed real-time PCR approach using locked nucleic acid (LNA)-modified primers to specifically detect SMN1. Methods: An LNA-modified primer pair with 3´ ends targeting SMN1 specific sites c.835-44g and c.840C was designed, and its specificity was examined by real-time PCR and Sanger Sequencing. A duplexed real-time PCR approach for amplifying SMN1 and control gene albumin (ALB) was developed. A randomized double-blind trial with 97 fresh peripheral blood samples and 25 dried blood spots (DBS) was conducted to evaluate the clinical efficacy of the duplexed approach. This new approach was then used to screen 753 newborn DBS. Results: The LNA-modified primers exhibited enhanced specificity and 6.8% increased efficiency for SMN1 amplification, compared with conventional primers. After stabilizing the SMN1 test by optimizing the duplexed real-time PCR approach, a clinical trial validated that the sensitivity and specificity of our new approach for detecting SMA patients and carriers was 100%. Using this new approach, 15 of the screened 753 newborns were identified as carriers via DBS, while the rest were identified as normal individuals. These data reveal a carrier rate of 1.99% in Hunan province, South Central China. Conclusions We have developed a novel, specific SMN1 detection approach utilizing real-time PCR with LNA-modified primers, which could be applied to both prenatal carrier and newborn screening.
