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 test the key indexes of full-field digital mammography to keep it in good condition.Methods The testing was carried out based on clinical experiences and GBZ 186—2007 Mammography Quality Control Testing Specification.Results The testing items and indexes were proposed to facilitate the staff to check and operate the machine.Conclusion Clinical safety of full-field digital mammography and image quality are both enhanced greatly.

BACKGROUND:During cervical posterior expansive open-door laminoplasty for multisegmental cervical spondylosis, spinal canal restenosis, loss of cervical lordosis, and axial symptoms are the important factors affecting curative effects. It is very necessary to maintain spinal canal expanded state and to reduce interference of the posterior cervical structure in the clinical treatment. OBJECTIVE:To observe clinical outcomes and short-term fol ow-up effect of posterior expansive open-door laminoplasty via titanium miniplate in treatment of cervical spondylotic myelopathy. METHODS:A total of 67 patients with cervical spondylotic myelopathy who underwent posterior expansive open-door laminoplasty at the Zhongshan Hospital, Xiamen University from April 2006 to April 2013 were retrospectively analyzed. Titanium miniplate group (n=27) received titanium miniplate fixation. Suture group (n=40) received traditional suture suspension. Al patients had decompression ranged from C 3-7 . Operation time, intraoperative blood loss, improvement rate of Japanese Orthopedic Association score during fol ow-up, value of cervical curvature, axial symptoms, and lamina opened angle were compared between the two groups. RESULTS AND CONCLUSION:No significant difference in operation time, intraoperative blood loss and improvement rate of Japanese Orthopedic Association score was detectable between two groups (P>0.05). Cervical curvature changes in both groups:loss of cervical curvature at 6 months postoperation was not significant in the titanium miniplate group, but cervical curvature partial y lost in the suture group, and significant differences in the cervical curvature were detected between the two groups (P<0.05). The incidence of axial symptoms was significantly lower in the titanium miniplate group than in the suture group at 6 months after surgery (P<0.05). During final fol ow-up, no significant difference in the lamina open-angle was detected between titanium miniplate group (35.2±6.2)° and suture group (34.0±4.7)° (P>0.05). These data suggested that posterior expansive open-door laminoplasty for treatment of cervical spondylotic myelopathy using both titanium miniplate and suture methods can obtain good clinical outcomes. However, titanium miniplate fixation can relieve postoperative axial symptoms and prevent loss of cervical curvature.
