ABSTRACT
Objective To understand the comparability of the detection results of four items (ALT ,AST , GGT ,ALP) of liver enzymology in 11 clinical laboratories in Xinjiang Production and Construction Corps (XPCC) and offer reference for improving mutual recognition of the results .Methods Eleven clinical labora-tories of XPCC organized the result comparability tests of 4 items of liver enzymology twice in 2017 ,and the samples with 5 batches were completed in each comparability test .One set of detection system in each labora-tory was used as comparability system according to comparability scheme .The detection results were analyzed through Robust Z Score and the evaluation criterion was :|Z|≤2 "satisfied";2< |Z|<3"warning";|Z|≥3 "not satisfied".Results The detection results of all 10 batch samples in 4 clinical laboratories showed |Z|≤2 in 2 comparability tests .In the first comparability test ,the detection results of 5 batch samples for 4 items were |Z|≤2 in 5 laboratories .In the second comparability test ,the detection results of 5 batch samples for 4 i-tems were |Z|≤2 in 8 laboratories ,but the ALT results of 5 batch samples in 1 laboratory showed positive deviation(Z≥3)and the GGT results of 5 batch samples in the other laboratory showed negative deviation (Z≤ -3) .Conclusion The 11 clinical laboratories in XPCC should continuously improve quality management system and make sure that the mutual recognition of the detection results of 4 items of liver enzymology is effective .
ABSTRACT
<p><b>OBJECTIVE</b>To report a new method of coracoid transposition for the treatment of complete dislocation of acromioclavicular joint and to evaluate its efficacy.</p><p><b>METHODS</b>We modified Dewar's surgical method as follows: (1) Two small incisions, a transversal incision on the acromioclavicular joint and a longitudinal incision on the coracoid, were made instead of a conventional large arc incision from the acromion to coracoid. (2) The foreign body in the acromioclavicular joint was cleared out. The chondral surface at the lateral segment of clavicle was resected to form a pseudarthrosis and meanwhile the residual joint capsule and ligaments were repaired. (3) The coracoid was moved to the anteroinferior edge of the clavicle instead of the anterior margin and (4) the coracoid was moved to the lateral border of the clavicle instead of the superior border of the coracoclavicular ligament.</p><p><b>RESULTS</b>The follow-up duration in 30 patients of the series was from 6 to 72 months (mean 41 months). Functional assessment was carried out by the criteria delineated previously by Karkson, in which Grade A was in 24 cases, Grade B in 4 cases, and C in 2.</p><p><b>CONCLUSIONS</b>This modified technique, having less postoperative complications and less injuries to tissues and according well with the requirement of biomechanics, can achieve a stable reduction of acromioclavicular joint with a good functional and cosmetic result and therefore is preferable to use clinically on a large scale.</p>
