Objective To study the significance of serum ischemia modified albumin(IMA) and brain natriuretic peptide(BNP) in patients with acute coronary syndrome. Methods Patients with acute coronary syndrome in six hours were divided into ST elevation myocardial infarction(STEM) of forty one cases, non-ST elevation myocardial infarction( NSTEM)of forty four cases and unstable angina of forty three cases. Twenty healthy people were selected as the control group. The serum IMA and BNP were detected. Results The levels of IMA and BNP in STEM group [(89. 6 ± 21.4) ABSU/ml, ( 324. 6 ± 39. 1 ) ng/L] were significantly higher than those in NSTEM group [( 79. 3 ±20. 5) ABSU/ml, (259. 7 ± 30. 5) ng/L]. The levels of IMA and BNP in NSTEM group were significantly higher than those in UA group[(67. 1 ± 18. 3)ABSU/ml,(124. 1 ±24. 3)ng/L].The levels of IMA and BNP in UA group were significantly higher than those in control group [( 56. 2 ± 15. 1 ) ABSU/ml, ( 15.9 ± 6. 7 ) ng/L]. Conclusion The levels of IMA and BNP in serum could forecast severity in patients with acute coronary syndrome.

BACKGROUND:The research for mesenchymal stem cels in the treatment of liver cirrhosis has made great progress. However,t-test analysis is often misused in clinical practice. OBJECTIVE:To analyze the efficacy and safety of umbilical cord mesenchymal stem cel therapy for liver cirrhosis by repeated measurement method. METHODS: A total of 27 patients with decompensated liver cirrhosis underwent conventional medical treatments, including liver protection treatment and symptomatic treatment. At 1 week after hospitalization, patients were given intravenous transplantation of umbilical cord mesenchymal stem cels (passages 2-4), cel viability≥ 90%, stem cel counting≥ 2×107 cels, four times with an interval of 5-7 days. Analysis of variance based on repeated measurement data was performed to analyze the liver function changes at different time after umbilical cord mesenchymal stem cel transplantation. RESULTS AND CONCLUSION: The results of univariate repeated measurement showed that at 2 and 3 months after treatment, the serum albumin level was increased and the total bilirubin level in serum was decreased significantly (P < 0.05); at 3 months after treatment, the content of aspartate aminotransferase decreased, and the content of cholinesterase increased significantly (P < 0.05). No patient appeared to have liver and other organ tumors during the observation period. These findings indicate that umbilical cord mesenchymal stem cel transplantation is effective and safe in the treatment of liver cirrhosis, which can significantly improve patient's liver functions.

According to clinical epidemiological researches, the usage of antibiotics in infant increases the risk of childhood asthma morbidity. The mechanism of this link is not entirely clariifed, and it is assumed of being related to side effects of antibiotics, which changes the colonization of normal intestinal lfora and reduces the diversity. It is clear that normal intestinal lfora of infant help to construct innate immune system and adaptive immune system, and forge immune tolerance. Therefore, normal intestinal lfora might be helpful in reducing allergies. The usage of antibiotics in early life changes the quantity and the composition of intestinal lfora, and breaks the balance of immune homeostasis, which might increase the risk of asthma morbidity. The abuse of antibiotics in children is a general phenomenon in China which needs attention from pediatricians.
