Congenital fiber-type disproportion (CFTD) is a rare form of congenital myopathy,characterized by non-progressive generalized muscle weakness from early childhood.Diagnosis depends on crucial histological abnormality that type 1 muscle fibers are consistently smaller than type 2 fibers in the absence of other specific histological abnormalities.Whether CFTD should be regarded as a distinct diagnostic entity has always been a controversial issue.Many pathogenic genes have been identified in recent years.This article reviews clinical manifestation,pathology,genetic diagnosis and treatment progress of CFTD.

Anti-angiogenesis therapies have emerged as new treatment strategies for several types of tumors. To date, the most studied programs are to find out effective medicines to block the vascular endothelial growth factor (VEGF) signaling pathway. However, VEGF inhibitors are not effective to all kinds of tumors.Thus there is a need to explore other angiogenesis signaling pathways. Recently, the Dll4-Notch pathway was identified as a new target in tumor angiogenesis. Moreover, an important feature in angiogenesis is the manifold ways in which the VEGF and Dll4-Notch pathways interact each other, which play critical roles in tumor angiogenesis. Therefore, the further exploration of these two pathways will provide more therapies for clinic to treat tumors.

Objective To assess the validity of using fasting plasma glucose （FPG） and HbA1c for the screening of diabetes. Methods 1118 subjects （489 men, 629 women） in Beijing area underwent an oral glucose tolerance test （OGTT） for screening diabetes. HbA1c was examined at the same time. They have never undergone OGTT and controlled plasma glucose levels by any methods. Their average age was 48±12 years. Results Using 1999 WHO criteria, 510 had normal glucose tolerance （NGT）, 35 had impaired fasting glucose（IFG）, 155 had impaired glucose tolerance （IGT）, 52 had IGT and IFG, 366 had diabetes. Using a receiver operating characteristic curve （ROC curve）, the optimal cut-point of FPG related to diabetes diagnosed by OGTT was 6.2mmol/L that was associated with a sensitivity and specificity of 85.0% and 90.4% respectively. Area under the curve was 0.943 （95% CI 0.9270.959）, a positive likelihood ratio （LR） was 8.9, and a negative LR was 0.2. The optimal cut-point of HbA1c related to diabetes diagnosed by OGTT was 6.2%, which was associated with a sensitivity and specificity of 86.6% and 77.5% respectively. Area under the curve was 0.896 （95% CI 0.8760.916）, a positive LR was 3.9, and a negative LR was 0.2. The cut-point of FPG related to IGT diagnosed by OGTT was 5.1 mmol/L, which was associated with a sensitivity and specificity of 65.2% and 68.3% respectively. Area under the curve was 0.729 （95% CI 0.6890.769）, a positive LR was 2.1, and a negative LR was 0.5. The cut-point of HbA1c related to IGT diagnosed by OGTT was 5.7%, which was associated with a sensitivity and specificity of 63.3% and 56.5% respectively. Area under the curve was 0.634 （95% CI 0.5910.677）, a positive LR was 1.5, and a negative LR was 0.7. Conclusions When FPG<7.0 mmol/L and ≥6.2 mmol/L or HbA1c≥6.2%, OGTT was necessary to confirm the diagnosis of diabetes. FPG or HbA1c was not reliable to identify IGT.

As a kind of polyphenolic phytoalexin,resveratrol exerts protective roles in anti-tumor,antiinflammatory and promoting metabolism.Resveratrol's anti-tumor mechanisms may be involved in upregulating tumor suppressor microRNAs and downregulating oncogenic microRNAs,and affect its relative pathways and target genes in different cancers such as colon cancers and breast cancers.This will provide a new theoretical basis for the further clarification of resveratrol-associated tumor suppressing mechanisms and its application to the clinical.

BACKGROUND: Total hip replacement is frequently used for osteoarthritis, rheumatoid arthritis, avascular necrosis of femoral head, et al. Although the operation is effective, some complications such as dislocation are serious and arouse more attention. OBJECTIVE: To review the research status of dislocation after total hip arthroplasty. RETRIEVAL STRATEGY: A computer-based online search of PubMed was undertaken for the English articles published between January 1997 and November 2007 with"hip replacement, dislocation". 496 related articles were collected from the above-mentioned database, including 445 original articles, and 57 review articles. Only articles ①about the influential factors for dislocation of hip joint; ②about the prevention and treatment of dislocation; ③highly correlated with the objective; and ④ published in recently or in authoritative journals were selected. Repetitive studies and Meta analyses were excluded. LITERATURE EVALUATION: Thirty-five articles were included, of which 9 were review articles and the others were clinical or empirical studies. DATA SYNTHESIS: ①Posterolateral approach in total hip arthroplasty increases the dislocation rate compared to anterior lateral approach and direct lateral approach. But when posterior articular capsule and extortor are sutured using absorbable thread before wound suture in total hip arthroplasty by posterolateral approach, the dislocation rate is increased and similar to anterior lateral approach and direct lateral approach. ②Large ball head of prosthesis can decrease the incidence of dislocation. In addition, the incidence of dislocation in prosthesis with skirted is less than prosthesis with no skirt. Elevated-rim acetabular liner can decrease but small offset distance can increase incidence of dislocation. ③Close reduction can cure early dislocation. If the dislocation is caused by infection, it is necessary to clear the wound, even take out the prosthesis for revision. Prosthesis location should be adjusted and hip joint with unbalance soft tissue should be treated by another surgery. ④If patients with recurrent dislocation, weak abductor, obvious soft tissue unbalance or other reason, it is better to use constrained prosthesis. CONCLUSION: Dislocation after total hip arthroplasty is caused by lots of complicated factors. With the acquaintance of factors and development of surgery techniques, the dislocation rate is significantly reduced than before. Complicated dislocation caused by soft tissue unbalance is the focus of future research.
