ABSTRACT
Objective: To investigate the effects and safety of recombinant human brain natriuretic peptide [rhBNP] in the treatment of elderly acute myocardial infarction induced cardiac failure
Methods: One hundred and forty-six patients who were diagnosed as elderly acute myocardial infarction induced cardiac failure in the hospital from July 2014 to July 2015 were selected. They were divided into a test group and a control group, 73 each. Patients in both groups were given conventional treatment such as stabilization of atherosclerotic plaques, anti-platelet and remodeling and reversion of myocardium. The curative effects and the incidence of adverse reactions of the two groups were observed
Results: The overall efficacy of the test group and the control group was 87.7% and 65.8% respectively, and the difference had statistical significance [P<0.05]. The heart rate, urine volume, n-terminal probrain natriuretic peptide level and left ventricular ejection fraction [LVEF] of both groups significantly improved after treatment, and the improvement of the test group was superior to that of the control group [P<0.05]. The serum creatinine of the test group remarkably reduced after treatment [P<0.05]. The incidence of hypotension and arrhythmia of the test group was lower than that of the control group during hospitalization period [P<0.05]
Conclusion: rhBNP can effectively relieve the clinical symptoms, cardiac function indexes and hemodynamic indexes of patients with elderly acute myocardial infarction induced cardiac failure, with a high safety. It can be extensively applied in the treatment of acute myocardial infarction in combination with cardiac failure
ABSTRACT
This paper is about the research on the growth of jyphal body of Hypsizygus marmoreus under the condition of different culture mediums, tempertures, pH, cardon and nitrogen sources. The result shows that Hypsizygus marmoreus can grow on various culture mediums. It grows best on the Culture medium of malt extract agar, but can not grow well on the PDA composite culture medium; the hyphal body can grow well at the temperture of 20—25℃, grows slowly at 10—30℃, but can not grow at 35℃; it can grow when pH is 5 to 8, but the best range of pH is 6.5—7.0; the nutriment assimilation is different with the different sources of carbon and nitrogen, the best carbon source is maltose, best nitrogen source is bacto-peptone.
