Coracoclavicular ligament reconstruction using autologous double-strand palmaris longus tendon and artificial ligament for the treatment of acromioclavicular joint dislocation / 中国骨伤

<p><b>OBJECTIVE</b>To investigate clinical effects of coracohumeral ligament reconstruction with autologous double-strand of long palmaris longus tendon and artificial ligament for the treatment of acromioclavicular joint dislocation.</p><p><b>METHODS</b>From April 2006 to June 2009, 31 patients with acromioclavicular joint dislocation were treated with coracohumeral ligament reconstruction using autologous double-strand palmaris longus tendon and artificial ligament. There were 18 males and 13 females, ranging in age from 18 to 60 years, with an average of 35 years. Twenty-six patients were acute trauma and other 5 patients were chronic trauma. Preoperative symptoms included different degrees of pain, restricted movement, and instability of acromioclaviecular joint. The X-ray showed acromioclavicular joint dislocation.</p><p><b>RESULTS</b>The patients had good incision union without vascular and nerve injuries. All the patients were followed up, and the average duration was 23 months. The JOA scores decreased from preoperative (38.8 +/- 1.5) to (73.2 +/- 1.1) at 1 month after operation,and (93.5 +/- 0.8)at the last follow-up. Twenty-eight patients got an excellent result, 2 good and 1 fair.</p><p><b>CONCLUSION</b>The reconstruction of coracohumeral ligament using autologous double-strand palmaris longus tendon and artificial ligament is an effective method for the treatment of acromioclavicular joint dislocation.</p>

Effects of genistein on secretion of extracellular matrix components and transforming growth factor beta in high-glucose-cultured rat mesangial cells.

The ideal treatment for diabetic nephropathy should slow the progress of renal failure, delay the initiation of dialysis, and protect residual renal function in patients receiving dialysis. Renal mesangial cells play an important role in these processes. In the current study, we investigated the effects of genistein on rodent renal mesangial cells cultured in a high-glucose environment. Since overexpression of the extracellular matrix (ECM) components (type IV collagen and fibronectin) and transforming growth factor beta (TGF-beta) have been previously implicated in the development of the renal glomerulus damage of diabetic nephropathy, we included these substances in our study. The results showed that high concentration of glucose (450 mg.dl(-1)) stimulated the synthesis of type IV collagen and fibronectin and the secretion of TGF-beta. These responses were attenuated by genistein (> or =5 micromol.l(-1)) in a dose- and time-dependent manner. In conclusion, we demonstrated that genistein could inhibit the secretion of ECM components and the expression of TGF-beta at both the protein and mRNA levels. These findings should be followed up by further studies and clinical trials to verify the potential therapeutic effects of genistein on diabetic nephropathy.
