RESUMO
Objective:To investigate the diagnostic value of CT-guided puncture biopsy combined with serum gamma-glutamyltransferase (GGT) and abnormal prothrombin (PIVKA-Ⅱ) in serum alpha-fetoprotein(AFP) negative primary liver cancer (PHC).Methods:Eighty patients with AFP negative PHC treatment in Fuyang Women and Children′s Hospital from January 2018 to March 2021 were selected as AFP negative PHC group, and another 85 patients diagnosed with benign liver tumor during the same period were selected as the control group retrospectively. The patients of the two groups underwent CT-guided biopsy and the levels of GGT and PIVKA-Ⅱ were detected. The single diagnostic value and combined diagnostic value of AFP negative PHC were analyzed by receiver operating characteristic (ROC) curve.Results:Seventy-five of the 80 patients in the AFP negative PHC group were confirmed as liver malignant lesions by biopsy, with a coincidence of 93.75%, and 84 of the 85 patients in the control group were confirmed as liver benign lesions by biopsy, with a coincidence of 98.82%. The levels of AFP, GGT and PIVKA-Ⅱ in AFP negative PHC group were significantly higher than those in the control group: (175.67 ± 39.58) μg/L vs. (18.74 ± 7.42) μg/L, (1 245.37 ± 255.41) U/L vs. (486.63 ± 89.05) U/L, (385.49 ± 30.27) AU/L vs. (25.84 ± 7.66) AU/L, there were statistical differences ( P<0.05). Spearman correlation analysis showed that serum AFP was positively correlated with GGT and PIVKA-Ⅱ ( r = 0.858 and 0.429, P<0.05). The results of ROC curve showed that the area under curve of CT-guided biopsy combined with GGT and PIVKA-Ⅱ in the diagnosis of AFP negative PHC was 0.877, the sensitivity was 91.19%, the specificity was 87.34%. Conclusions:CT-guided biopsy combined with GGT and PIVKA-Ⅱ detection of AFP negative PHC can effectively improve the diagnostic value.
RESUMO
Objective To investigate the effect of optimizing rescue time for patients with acute st-elevation myocardial infarction (STEMI) in the hospital. Methods A retrospective analysis of the clinical data of 133 patients with ST-elevation myocardial infarction who were hospitalized in the first affiliated hospital of university of science and technology of china during July,2016 to June,2017 was performed. Timeline in the rescue, the result of coronary reperfusion and satisfaction degree of patients were analyzed. Results The rapid evaluation time (F=2.609, P=0.046),emergency handling time(F=7.581, P=0.032), login and logout time (F=5.667, P=0.017)and visit-ballon time (F=8.942, P=0.007) were shortened quarter by quarter . The average time of each project in the four quarters showed a statistically significant difference. The difference of TIMI classification of coronary flow reperfusion among the four quarters was statistically significant (H=8.402, P=0.038). The satisfaction degree of each quarter showed a statistically significant difference (the third quarter of 2016:94.68±2.38, the fourth quarter of 2016:96.72± 5.10, the first quarter of 2017:97.23 ± 7.64,the second quarter of 2017:98.36 ± 4.86;F=7.891,P=0.048). Conclusions Enhancing timeliness of emergency care can remarkably shorten rescue time, improve satisfaction degree of patients and help to improve the success rate of emergency treatment for patients with STEMI.
