Fingertip replantation at the eponychial level with venous anastomosis: an anatomic study and clinical application.

We present an anatomic study of the vein distribution at the eponychial level, in order to standardize outpatient fingertip replantation. The cross sectional anatomy of 100 fingers was studied by dissection following dye injection. The distribution of the veins >0.

The A242T mutation in the low-density lipoprotein receptor-related protein 5 gene in one Chinese family with osteosclerosis.

Objective: Osteosclerosis (OMIM: 144750) is a type of autosomal dominant bone disease caused by a mutation in the low-density lipoprotein receptor-related protein 5 (LRP5) gene. The case of a Chinese family with two affected individuals is reported in the present study in order to investigate the clinical characteristics and virulence genes of this sclerosing bone disorder.

Methods: Biochemical and radiographic examinations and bone mineral density (BMD) and genetic analyses were performed in two patients and eight other family members.

The skeletal effects of thiazolidinedione and metformin on insulin-resistant mice.

To explore the skeletal effects and the potential underlying mechanisms of treatment with two thiazolidinediones (rosiglitazone and pioglitazone) or metformin in insulin-resistant mice, 24 female, 12-week-old C57BL6J ob/ob mice were evaluated according to the following treatment groups for 6 weeks: placebo group, pioglitazone group (Pio), rosiglitazone group (Rosi), and metformin group (Met). Bone mineral density (BMD), bone microarchitecture, bone histomorphometry, and expression of three phenotype-specific gene markers, including bone morphogenetic protein 2 (Bmp2), runt-related transcription factor 2 (Runx2), and fatty acid-binding protein 4 (Fabp4), were compared across the four groups. At the femur, the Met group had the highest BMD (0.

NIRF is frequently upregulated in colorectal cancer and its oncogenicity can be suppressed by let-7a microRNA.

Np95 ICBP90 RING finger (NIRF) is essential for the regulation of cell proliferation and has been implicated in tumorigenesis. However, the role of NIRF in colorectal cancer (CRC) remains unclear. In this study, we demonstrated that NIRF expression was aberrantly increased in CRC tissues and associated with poor overall survival.

Waldeyer's fascia: anatomical location and relationship to neighboring fasciae in retrorectal space.

Purpose: The term Waldeyer's fascia has caused confusion in surgery for rectal cancer. We have therefore dissected endopelvic fasciae to clarify the structure and location of Waldeyer's fascia, and to determine its anatomical relationships with adjacent fasciae.

Methods: Twenty cadavers (13 males and 7 females) were dissected.

The virulence gene and clinical phenotypes of osteopetrosis in the Chinese population: six novel mutations of the CLCN7 gene in twelve osteopetrosis families.

Osteopetrosis is a heritable bone disorder resulting from a deficiency of or a functional defect in osteoclasts. We aimed to characterize the molecular defects and clinical manifestations in Chinese patients with osteopetrosis by studying 12 unrelated osteopetrosis families. The entire coding region and adjacent splice sites of the CLCN7, TCIRG1, LRP5 and SOST genes were amplified and directly sequenced.

Association between vitamin D and risk of colorectal cancer: a systematic review of prospective studies.

Purpose: To conduct a systematic review of prospective studies assessing the association of vitamin D intake or blood levels of 25-hydroxyvitamin D [25(OH)D] with the risk of colorectal cancer using meta-analysis.

Methods: Relevant studies were identified by a search of MEDLINE and EMBASE databases before October 2010 with no restrictions. We included prospective studies that reported relative risk (RR) estimates with 95% CIs for the association between vitamin D intake or blood 25(OH)D levels and the risk of colorectal, colon, or rectal cancer.
