Objective: To study the clinical role of the variation of serum matrix metalloproteinase-8 (MMP-8) concentration in patients with acute coronary syndrome (ACS). Methods: ELISA method was adopted to detect serum MMP-8 concentration and to observe concentration's differences and features among 80 selected ACS cases (43 acute myocardial infarction and 37 unstable angina pectoris), 43 stable angina pectoris (SAP) cases and 37 control cases. And meanwhile the atherosclerosis risk factors of each case, such as age, sex, hypertension, body mass index, smoking, family history, diabetes, and hyperlipidemia were collected and analyzed as a whole. Results: First, serum MMP-8 concentration reached the highest point in ACS, and there was significant difference between SAP and control groups (P<0.01). Second, serum MMP-8 in AMI was much higher than that in UAP with significant difference (P<0.01). There was no difference between UAP and SAP groups (P>0.05). Third, Logistic regression analysis revealed that serum MMP-8 concentration might be the indicator of ACS (B=4.493, P=0.000), particularly, that of AMI (B=9.961, P=0.000). Fourth, linear correlation and linear regression analysis found that only neutrophil was likely to influence serum MMP-8 concentration (r=0.274, P=0.001). Fifth, in the diagnosis of ACS, the area under ROC curve of MMP-8 was 0.785, the sensitivity and specificity were 68.6% and 76.5%, respectively. Conclusion: 1 Serum MMP-8 concentration has close relationship with the occurrence of ACS, particularly with AMI; 2 Serum MMP-8 concentration may be one of the predicting indicators of ACS and particularly of AMI; 3 Neutrophil may be correlated with serum MMP-8 concentration; 4 MMP-8 is of somewhat valuable in diagnosing ACS.

[Objective]To evaluate the therapeutic effect of treating AO type C fracture of the distal radius with open reduction LCP plate internal fixation.[Method]From Jan.2004 to Jan.2007,37 cases of AO type C fractures of the distal radius were treated with LCP plate internal fixation.All cases were fixated through volar approach,the length of radius,waist joint angle were recovered,screwed the plate,the exposure of dorsal soft tissues could be obtained by internal-rotate radius,allo-bone graft,and aoto-bone graft was necessary for the case with bone defect.Passive wrist motion,active finger motion and forearm rotation were encouraged immediately after surgery.Active wrist motion was suggested seven days postoperatively.[Result]The 37 cases were followed up for 8 to 21 months,with an average time of 11 months.X-ray pictures showed that one-stage union was achieved in the patients,with a mean healing time of eight weeks.No such complications were found as infection,non-union,loosing of nails,carpal tunnel syndrome or medium neuritis.Their clinical outcomes were evaluated according to modified McBride grading system.Twenty-five were rated as being excellent,eight as good and four as fair,with their good-excellent rate as being 89.18%.[Conclusion]Treatment of type C distal radius fracture with LCP plate internal fixation has many advantages,such satisfactory reduction,rigid fixation,and excellent function.
