ABSTRACT
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.
ABSTRACT
OBJECTIVE@#To investigate the clinical and pathological characteristics of sinonasal neoplasms.@*METHOD@#A cohort of 333 patients with sinonasal neoplasm, which were confirmed by surgical pathology, were enrolled in this study. The clinicopathological characteristics, in terms of age, sex, location, and disease constituent ratio were retrospectively reviewed.@*RESULT@#(1) In this series of patients, there were 200 males and 133 females, aged from 2 to 84 years, with a median of 54 years. The benign to malignant ratio was 1.1:1. As for their origination, 144 tumors arose from the nasal cavity, while, 191 tumors derived from sinus, including 90 from maxillary sinus, 31 from frontal sinus, 46 from ethmoid sinus, and 24 from sphenoidal sinus. (2) Disease constituent ratio decreased in order of epithelial tissue, soft tissue, lymphohematopoietic tissue, bone and cartilaginous tissue, ectopic intracranial tumors. The five most frequent malignant tumors were squamous carcinoma, lymphoma, adenoid cystic carcinoma, malignant melanoma and esthesioneuroblastoma, while, benign tumors ranked in the top five were papilloma, fibroma, osteoma, angioma and ectopic intracranial tumors,respectively. (3) Of 200 cases arising from epithelium, 118 were benign, 82 were malignant, and the benign to malignant ratio was 1.4:1. Of 68 cases from soft tissue, 37 were benign and 31 were malignant tumors (ratio, 1.2:1). Among the 22 cases from bone and cartilaginous tissue, 17 were benign and 5 were malignant (ratio, 3.4:1). With respect to the 29 cases from lymphohematopoietic tissue, the majority of tumors were malignant (28 cases), with only one benign case. In addition, ectopic intracranial tumors were also observed. Besides the above all, 12 cases of other types were found in this work.@*CONCLUSION@#Neoplasms from different parts of nasal cavity and paranasal sinus have specific clinical characteristics. The pathological types of these tumors may be highly diverged. The diagnosis and differential diagnosis depend mainly on pathological examination. Comprehensive treatment, which employs surgery in combination with other modalities, is the main strategy for these tumors.
