Objective To investigate the association of chest pain patients with primary level in high-sensitivity troponin T (hs-cTnT) level no more than 14 ng/L in the onset of acute myocardial infarction in pa-tients with chest pain. Methods We enrolled 3 096 participants from January 2012 to December 2013 in West China Hospital, Sichuan University. All patients were classified two groups (hs-cTnT > 14 ng/L, hs-cTnT ≤14 ng/L and no ischemia on ECG) according to hs-cTnT levels and ECG. We evaluated the risk of myocardial in-farction and death and negative predictive value in 30 days. Results Thirty-seven patients were diagnosed in having acute myocardial infarction (AMI) and 4 patients were dead in the hs-cTnT > 14 ng/L group in 30 days in the absolute risk 2.35(1.86-2.74) and 0.29(0.12-0.53); 9 patients were diagnosed as having AMI and no patients were dead in the hs-cTnT ≤ 14 ng/L group in 30 days in the absolute risk 0.58 (0.42-0.74). Conclu-sion Chest pain patients whose primary levels no more than 14 ng/L in hs-cTnT with no ischemia on ECG can be ruled out AMI in negative predictive value 99.6%. the levels of hs-cTnT which were dynamic monitored at least 5 h and still no more than 14 ng/L can rule out AMI directly.

Objective To explore the effects of nursing intervention based on Information-motivation-behavioral model (IMB) on self-efficacy and quality of life of patients with primary liver cancer. Methods A total of 84 patients with primary liver cancer who were hospitalized in the First Affiliated Hospital of Ji'nan University from January to December in 2016 were selected by convenience sampling method and divided into control group (40 cases) and observation group (44 cases) according to the time of admission. The patients in the control group received routine care, while the patients in the observation group received nursing intervention based on IMB. Chinese Strategies Used by People to Promote Health (C-SUPPH) and Quality of Life-Liver Cancer (QOL-LC) were applied to investigate patients' self-efficacy and quality of life before and after intervention, so as to evaluate the effects of intervention. Results The C-SUPPH and QOL-LC scores of the observation group and the control group were (87.18±14.83), (105.01±18.56) and (78.65±15.75),(94.75±18.15) respectively on the day of discharge, and the differencs were statistically significant (t=-2.557,-2.068; P< 0.05). The C-SUPPH and QOL-LC scores of the observation group and the control group were (92.34±16.04), (123.11±20.86) and (80.50±15.86), (101.90±19.95) respectively 1 month after discharge, and the differences were statistically significant (t=-3.397,-4.753; P< 0.05). Conclusions Nursing intervention based on IMB can improve the self-efficacy and quality of life of patients with primary liver cancer, which is worthy of clinical promotion.
