Purpose: The aim of this study is to compare the clinical and radiographic results and the complication rate between early and delayed surgical treatment of acromioclavicular joint (ACJ) dislocation. Methods: Publications in the management of ACJ dislocation are identified from the PubMed database between January 1993 and December 2013 using “acromioclavicular joint” and “dislocation” as keywords. The eligibility criteria included are as follows: (1) ACJ dislocation; (2) intervention, early compared with delayed surgical treatment or the surgical treatment for acute compared with chronic ACJ dislocation; (3) human; and (4) English articles. Exclusion criteria consist of the following: (1) type I and type II ACJ dislocation, (2) no definition of the time of early and delayed surgery in studies, (3) no comparison between the clinical result of early and delayed surgery in studies, (4) laboratory studies, radiographic studies, biomechanical studies, (5) the cases including fractures or revisions in studies, and (6) systematic analyses. Results: Eight studies comparing early and delayed surgical treatment of ACJ dislocation are included in this systematic review. According to Constant scores and shoulder subjective value, early surgery has better functional outcomes than delayed surgery in the treatment of ACJ dislocation (P < 0.05). Partial-dislocation/re-dislocation is found at 26.0 % in early and 38.1 % in delayed surgical treatment (P < 0.05). The rate of CC ossification in early surgical treatment is found as the same as the delayed. The complication rates are found at 12.5 % in early surgical treatment and 17.7 % in the delayed, which is not significantly different. Conclusion: Early surgical treatment may have superiority to the delayed procedure in the management of ACJ dislocation with better functional outcomes and more satisfied reduction. However, high-quality evidence studies are required to provide stronger support for this opinion in the future. Level of evidence: IV. © 2014, Springer-Verlag Berlin Heidelberg. Source

Background/Aims: Neural stem cells (NSCs) hold considerable potential as a therapeutic tool for repair of the damaged nervous system. In the current study, we examined whether transplanted N-acetyl aspartyl-glutamate synthetase (NAAGS)-activated NSCs (NAAGS/NSCs) further improve neurological recovery following traumatic brain injury (TBI) in Sprague-Dawley rats. Methods: Animals received TBI and stereotactic injection of NSCs, NAAGS/NSCs or phosphate buffered saline without cells (control) into the injured cortex. NAAGS protein expression was detected through western blot analysis. Dialysate NAAG levels were analyzed with radioimmunoassay. Cell apoptosis was detected via TUNEL staining. The expression levels of specific pro-inflammatory cytokines were detected with enzyme-linked immunosorbent assay. Results: Groups with transplanted NSCs and NAAGS/NSCs displayed significant recovery of the motor behavior, compared to the control group. At 14 and 21 days post-transplantation, the motor behavior in NAAGS/NSC group was significantly improved than that in NSC group (p<0.05). Additionally, transplanted NAAGS/NSCs inhibited cell apoptosis and the expression levels of specific pro-inflammatory cytokines, including interleukin-1β, interleukin-6 and tumor necrosis factor-α. Conclusion: Our results collectively demonstrate that NAAGS/NSCs provide a more powerful autoplastic therapy for the injured nervous system. © 2014 S. Karger AG, Basel. Source
