Ultrasound-guided needle-knife for De Quervain's disease: A protocol for systematic review and meta-analysis

BACKGROUND

De Quervain's disease is a kind of aseptic inflammation caused by repeated frictions of tendons in the tendon sheath of the styloid process of the radius. The main symptoms are protuberance and pain of the styloid process of the radius, accompanied by aggravation of pain during the movement of the wrist and thumb. The advantages of needle-knife are simple operation, obvious therapeutic effect and high safety. It can also be used to treat De Quervain's disease. Ultrasound gives a precise visualization of the thickness. The purpose of this study is to evaluate the efficacy and safety of ultrasound-guided needle-knife in the treatment of De Quervain's disease and to provide the latest basis for clinical application.

METHODS

The computer will be used to search all randomized controlled trials (RCTs) about ultrasound-guided needle-knife treatment of De Quervain's disease in the following database: PubMed, Web of Science, Cochrane Library, Cochrane Central controlled Trials Registry (CENTER), EMBASE, China National knowledge Infrastructure (CNKI), Wanfang data, Chinese Biomedical Literature Database (CBM), VIP Database (VIP). The effectiveness and safety of ultrasound-guided needle-knife in the treatment of De Quervain's disease were evaluated with pain intensity, wrist function as the main index and wrist range of motion, adverse events and quality of life as the secondary index. Revman5.3 software was used for data processing.

RESULTS

This study will provide the latest evidence for the Ultrasound-guided needle-knife for De Quervain's disease.

CONCLUSION

The conclusion of this study is to evaluate the effectiveness and safety of ultrasound-guided needle-knife in the treatment of De Quervain's disease.

FRK suppresses the proliferation of human glioma cells by inhibiting cyclin D1 nuclear accumulation

The Fyn related kinase (FRK) is a noteworthy member of the Src non-receptor tyrosine kinase family for its distinctive tumor suppressive function. Recently, we have shown that FRK plays a protective role against the progression of glioma by suppressing cell migration and invasion. However, it is unclear whether the cell growth of glioma is also regulated by FRK and by which mechanism FRK alters its specific biological functions. In the current study, we found that FRK over-expression significantly suppressed the proliferation of glioma cells. In contrast, FRK knockdown by siRNA promoted glioma cell growth. In addition, FRK over-expression caused G1 phase arrest as well as apoptosis of glioma cells. Further investigation disclosed that FRK-induced G1 arrest was accompanied by down-regulation of hyperphosphorylated retinoblastoma protein (pRb), which led to the consequent suppression of E2F1. More importantly, we found that over-expression of FRK inhibited proper cyclin D1 accumulation in the nucleus of proliferating cells. Taken together, our results demonstrate a combined mechanism for the anti-proliferative effects of FRK by inhibiting cyclin D1 nucleus accumulation and pRb phosphorylation in glioma cells.
