Objective To evaluate the effectiveness of Xingnaojing (XNJ) injection in the treatment of acute alcohol intoxication. Methods The Cochrane library (Issue 4, 2008), MEDLINE (1989 to 2008), WANFANG database (1991 to 2008), CBM (1991 to 2008), and CNKI (1991 to 2008) were searched. The quality of included studies was assessed according to the criteria recommended Cochrane Collaboration.Meta-analyses were performed using RevMan 4.2.2 software. Results Twenty seven trials, all published in China were included. The quality of these studies was low. Meta-analyses showed that normal treatment plus XNJ could significantly shorten action time [WMD= – 90.62 min, 95%CI (– 121.12, – 60.11)] and effective time [WMD= – 124.97 min, 95%CI (– 183.54, – 66.40)]. Normal treatment plus XNJ was similar with normal treatment plus naloxone in action time. No significant differences were observed in effective time between naloxone and XNJ. Conclusions It shows that XNJ injection plus western medical therapy is superior to western medical therapy. The curative efficacy of XNJ and Naloxone was similar.
ObjectiveTo review the concept and methods of femoral bone tunnel positioning in anterior cruciate ligament (ACL) reconstruction, in order to provide a reference for clinical treatment. MethodsThe relevant literature on the concept and methods of femoral bone tunnel positioning in ACL reconstruction in domestic and international research was extensively reviewed. ResultsThe position of the femoral bone tunnel is a key factor in determining the prognosis of ACL reconstruction. The concept of femoral bone tunnel positioning in ACL reconstruction has experienced isometric reconstruction, anatomical reconstruction, Ribbon-like theory, I.D.E.A.L. theory, and nearly isometric reconstruction theory. The femoral bone tunnel positioning technique is also changing with the in-depth study of the anatomy and biomechanics of the ACL, and each bone tunnel positioning technique has its own advantages and disadvantages. Over-The-Top technique is now mainly used for ACL revision; the clock-face positioning method is basically no longer applicable due to the large error, poor stability, and low retrievability; the bone landmarks positioning method (the lateral condyle of the femur’s Resident’s ridge and bifurcation ridge, and the the apex of the deep cartilage), which is now mostly used clinically due to the more constant anatomical landmarks. The quadrant method under X-ray fluoroscopy is more cumbersome to implement intraoperatively, so it is mainly used for academic research; computer navigation-assisted positioning has gradually become popular in recent years, which is highly accurate, avoids the influence of human factors on the positioning of the bone tunnel, and has a very good prospect of application; three-dimensional printing-assisted positioning technology, which is accurate in positioning, with a high degree of reproducibility and a short learning curve. ConclusionThe concept of femoral bone tunnel positioning for ACL reconstruction has undergone several evolutions, reflecting the deepening of the understanding of ACL and the improvement of the clinical results of reconstruction. The precision, personalization, and intelligence of positioning techniques are the focus of current and future development.
