Alagille syndrome （AGS, OMIM#118450） is a multi-system, autosomal dominant disorder with variable clinical manifestation, which primarily affects the liver, heart, eyes, face, and skeleton. The estimated incidence of AGS is 1 in 70000 births of all races worldwide; however it has been rarely reported in Chinese children. We treated a Chinese boy presenting with jaundice, pruritus and gowth failure finally who had been diagnosed as having AGS. Informed consent was obtained from the legal guardian of the child before reporting.

For the treatment of osteoporotic vertebral compression fractures （OVCFs）, percutaneous kyphoplasty （PKP）enables rapid pain relief and spinal stabilization, as well as correction of kyphosis. Although serious complications such as pulmonary embolism and spinal cord and nerve damage may occur,1 recurrence of pain after PKP is unlikely to require medical attention. The present study analyzed the causes of post-operative residual pain by reviewing the clinical data of 16 from 121 patients with OVCFs who underwent PKP from August 2005 to April 2009. METHODS

The global spin alignment of vector mesons has been observed by the STAR collaboration at the Relativistic Heavy Ion Collider （RHIC） at Brookhaven National Laboratory （BNL）.It provides a unique opportunity to probe the correlation between the polarized quark and antiquark in the strongly coupled quark-gluon plasma （sQGP） produced in relativistic heavy ion collisions,opening a new window to explore the properties of s *** addition,spin alignments of vector mesons have also been observed in other high-energy particle collisions such as e+e-annihilations at high energies where hadron production is dominated by quark fragmentation *** results obtained are quite different from those obtained in heavy ion collisions where quark coalescence/combination mechanism dominates suggesting strong dependence on hadronization *** comprehensive studies in different hadronization processes are *** this article,we present a brief review of theoretical and experimental advances in the study of vector meson’s spin alignments in a variety of high-energy particle collisions,with emphasis on hadronization mechanisms.
