Objective To evaluate the early diagnostic value of circulating microRNA-1 (miR-1) on acute myocardial infarction (AMI). Methods A prospective cohort study was conducted. The patients with chest pain admitted to the Second People's Hospital of Wuxi from November 2012 to June 2015 were enrolled. According to AMI diagnostic criteria, the patients were divided into AMI group and non-AMI group, and healthy individuals during the same period were served as heath controls. The venous samples of the onset patients were collected within 3 hours after admission. The plasma miR-1 was determined by real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR), and the levels of plasma cardiac troponin I (cTnI) and MB isoenzyme of creatine kinase (CK-MB) were measured by electrochemiluminescence. The correlation between plasma miR-1 and cTnI as well as CK-MB was performed by Spearman analysis. The early diagnostic performance of plasma miR-1, cTnI, and CK-MB for AMI was estimated by receiver operating characteristic (ROC) curve analysis. Results There were 127 patients in AMI group, and 107 in non-AMI group, including 82 patients with angina pectoris, 2 with pulmonary embolism, 3 with aortic dissection, 2 with acute pericarditis, 3 with myocarditis, 13 with acute heart failure, and 2 with peptic ulcer. Ninety volunteers were served as healthy controls. There was no difference in clinical characteristics including gender and hyperlipidemia between AMI group and non-AMI group. The expressions of plasma miR-1, cTnI and CK-MB were significantly increased in AMI patients as compared with those of the healthy controls [miR-1 (2-ΔΔCt): 4.32±2.60 vs. 1.44±0.75 and 0.98±0.18, cTnI (μg/L): 3.23 (0.63, 10.70) vs. 0.02 (0.00, 0.17) and 0.00 (0.00, 0.00), CK-MB (U/L): 32.40 (14.20, 95.40) vs. 14.40 (11.20, 17.10) and 8.90 (8.28, 9.50), all P < 0.01]. The expression of plasma miR-1 had a significantly positive correlation with cTnI and CK-MB in AMI patients (r1 = 0.395, r2 = 0.490, both P < 0.000). It was demonstrated by ROC curve analysis that the area under ROC curve (AUC) for the diagnostic value of miR-1 on AMI was 0.905 [95% confidence interval (95%CI) = 0.860-0.950, P = 0.000], the sensitivity was 86.6%, and the specificity was 95.4%; the AUC for cTnI was 0.908 (95%CI = 0.870-0.946, P = 0.000), the sensitivity was 81.9%, and the specificity was 95.9%; the AUC for CK-MB was 0.795 (95%CI = 0.736-0.854, P = 0.000), the sensitivity was 63.0%, and the specificity was 92.9%. Conclusions Plasma miR-1 has the capacity in early diagnosis of AMI, superior to CK-MB, and equal to cTnI. It can provide additional diagnostic information beyond cTnI. The diagnostic accuracy for early AMI can be improved with the combination of plasma miR-1 and cTnI.

OBJECTIVETo discuss surgical approaches of ossification of the posterior longitudinal ligament (OPLL) of cervical spine.

METHODSBetween June 2005 to July 2010, 36 patients with OPLL of cervical spine were reoperated. There were 23 male, 13 female, age from 39 to 72 years (mean 57 years). The time of the first operation to the reoperation were 4 months to 24 years, an average of 3.9 years. Among 20 patients underwent anterior corpectomy and fusion (ACD) at first operation, 14 cases combined stenosis of cervical spinal canal, 10 cases were insufficient decompression of OPLL, 5 cases injured of cervical spinal cord during the first operation, 1 case was adjacent disc herniation. Among 14 cases underwent expensive open-door laminoplasty (ELAP) at first operation, 6 cases were insufficient decompression of OPLL, 4 cases were inadequate decompressed segment, 2 cases were cervical segmental kyphosis, 2 cases were progression of OPLL combined with disc herniation. Among 2 cases underwent combined approach at first operation, 1 case was insufficient decompression of OPLL, the other was adjacent disc herniation. Their pre- and post-operative X-ray, CT and MRI were analyzed. The complications of reoperation were recorded.

RESULTThere were 30 patients followed-up, with a period of 1.5 - 4.0 years, average 1.8 years. With 36 patients, none had deterioration, 2 patients had no recovery post-reoperation, 34 patients had 31.2% Japanese Orthopedic Association score improve rate. Among 22 cases underwent ELAP at second operation, 3 cases had postoperative segmental palsy. Among 14 cases underwent ACD at second operation, 3 cases had intraoperative dural defects.

CONCLUSIONSurgical strategy for OPLL of cervical spine should consider the type of OPLL and stenosis of cervical spinal canal.
