ABSTRACT
OBJECTIVE: To investigate the influences of different treatment patterns on the cost-effectiveness in treating acute myocardial infarction (AMI). METHODS: Data about referral of AMI patients who called for help because of chest pain to the nearby hospitals from October 2003 to December 2005 were collected from the Guangzhou 120 Call Center. All these patients were followed up 6 months after discharge to survey the cost during hospitalization, major treatment, prognosis (death, re-infarction, stroke etc. ), and secondary prevention for coronary heart disease. We used SF-36 scale was used to quantify the health status. RESULTS: 101 AMI patients referred to grade 2 A hospitals (Group A) and 137 patients referred to grade 3 A hospitals (Group B) were successfully followed up. The cost during hospitalization of Group B was (33965 +/- 963) yuan RMB, significantly higher than that of Group A (18943 +/- 893) yuan, P = 0.021). 11 patients of Group B died, and 5 patients suffered from stroke with the mortality and stroke rate both significantly lower than those of Group A (18/101 and 12/101, P = 0.022, P = 0.015). There was no significant difference in the re-infarction rate between the 2 groups. The scores in physical function, general health status, vitality, social function, role-emotional, mental health of Group B were all significantly higher than those of Group A (all P < 0.05) , however, there were not significant differences in body pain and role-physical between these 2 groups. The smoking cessation rate, specialist outpatient department follow-up rate, statins use rate of Group B were significantly higher than those of Group A (P = 0.017, P = 0.016, P = 0.038). CONCLUSION: The 120-grade 3 A hospital CCU pattern is more cost-effective in treatment of AMI.

<p><b>OBJECTIVE</b>To investigate the value of urinary S100B protein and lactate/creatinine ratio determination in early identification of neonatal hypoxic-ischemic encephalopathy (HIE).</p><p><b>METHODS</b>The levels of urinary S100B protein and urinary lactate/creatinine ratio were detected in 58 full-term newborn infants with HIE on the first, second and third day after birth. The severity of clinical manifestations, including the degree of encephalopathy, was assessed within 7 days after birth. Twenty five normal neonates were enrolled into the control groups.</p><p><b>RESULTS</b>(1) The urinary S100B level of HIE neonates was significantly higher in samples collected throughout the monitoring period than those of the normal control groups (all P < 0.001). The urinary lactate/creatinine ratio of the HIE neonates was also significantly higher than that of normal control groups within the first day (P < 0.001). (2) A significantly positive correlation was found between the level of urinary S100B protein within three days and the urinary lactate/creatinine ratio within the first day and between the level of urinary S100B protein within three days and clinical degree (P < 0.05). (3) When S100B concentration was 0.47 microg/L and urinary lactate/creatinine ratio was 0.55, the sensitivity and specificity of detecting the third day urinary S100B alone, were respectively 90.4%, 91.9%. Detecting it associated with the first day urinary lactate/creatinine ratio could increase the sensitivity and specificity (respectively 98.8% and 97.4%) for predicting development of HIE.</p><p><b>CONCLUSION</b>On the basis of clinical manifestations of asphyxic neonatals, detecting the level of urinary S100B within three days and the first day urinary lactate/creatinine ratio may be of important value in early diagnosis and grading of HIE.</p>
