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
Objective:To study CT and MRI radiological expression of benign and malignant meningiomas to provide a reliable evidence for clinical surgery scheme determination. Methods: The radiological and pathological data of 40 cases with meningiomas undergoing surgery in hospital were analyzed, and the benign and malignant lesions of meningiomas were judged according to imaging features such as meningioma shape, edge, signal or density, peritumorous edema, intratumorous calcification, multiple tumors, tumor brain interface status etc.Results: (1)Tumor signal or density: T1 signal inhomogeneous in 6 cases(15.0%), T2 signal inhomogeneous in 8 cases(20.0%), the signal homogeneous in 26 cases (65.0%), CT density is inhomogeneous in 15 cases(37.5%), CT density is homogeneous in 25 cases(62.5%); (2)Tumor edge: regular in 27 cases(67.5%), coarse, irregular, lobulated, with mural nodules in 13 cases(32.5%); (3)Dural tail sign in 36 cases (90.0%); (4)Skull invasion in 6 cases(15.0%); (5)Calcification within the tumor in 7 cases(17.5%); (6)Peritumoral edema in 14 cases(35.0%); (7)Multiple tumors in 6 cases(15.0%); (8)Enhance performance: Obvious homogeneous enhancement in 27 cases(67.5%), Obvious inhomogeneous enhancement in 13 cases(32.5%).Conclusion: Benign and malignant meningiomas with a certain radiological feature, the curative effect and prognosis may be properly evaluated by the radiological expression of meningiomas.
