Preliminary study of 3T 1H MR spectroscopy in bone and soft tissue tumors.
Magnetic resonance spectroscopy (MRS) is one method that can examine noninvasively the alive specimen of the organ, metabolism of the organ and cell, and the biochemistry change. MRS provides the biochemistry information that may be used to diagnose tumors or differentiate the malignant tumor from benign. The objective of this study is to investigate the benign and malignant bone and soft tissue tumors by 1H-MR spectroscopy ((1)H-MRS) on a 3 Tesla MR scanner, then to assess the usefulness of (1)H-MRS in diagnosing bone and soft tissue tumors and distinguishing benign from malignant tumors. ⋯ The increase of Cho level measured by (1)H-MRS is related to the bone and soft tissue malignant tumor. Cho/Cr in malignant tumor was higher than in benign tumor, so they will play a vital role in the diagnosis and differential diagnosis of bone and soft tissue tumors.

Association of TBX5 gene polymorphism with ventricular septal defect in the Chinese Han population.
Congenital heart disease is a diverse group of diseases determined by genetic and environmental factors. Considerable research has been done on genes associated with development of the heart. A recent focus is the role of transcription factor TBX5 in the development of atria, left ventricle and conduction system. As part of a larger study, high density, single nucleotide polymorphism (SNP) scanning was used to explore the relationship between TBX5 gene polymorphism and susceptibility to ventricular septal defect not associated with forelimb malformation in the Chinese Han population. ⋯ TBX5 is associated with the occurrence of ventricular septal defect and may be a predisposing gene to congenital heart disease in Han Chinese. This finding has set a direction for further genetic and functional studies.
