Résumé
OBJECTIVE: To investigate the effect of electroacupuncture (EA) on the expression of interleukin-8 (IL-8), interleukin-10 (IL-10), tyrosine hydroxylase (TH), β3-adrenergic receptor (β3AR), and endothelial nitric oxide synthase (eNOS) in myocardial tissue in ischemic myocardial injury rats, so as to reveal its underlying mechanisms in myocardial protection via anti-inflammation and sympathetic nerve remodeling. METHODS: A total of 48 male Sprague-Dawley rats were randomly divided into sham-operation (sham, n＝9), sham ＋EA (n＝9), model (n＝15) and EA (n＝15) groups. The myocardial ischemia (MI) model was established by ligation of the left anterior descending branch of the left coronary artery. EA (2 Hz/15 Hz，1.5－2 mA) was applied to bilateral "Neiguan" (PC6) for 30 min, once daily for 4 days. The myocardial infarct size was detected by 2, 3, 5 triphenyltetrazolium chloride (TTC) staining, myocardial histopathological changes and inflammatory infiltration were assessed by H．E. staining, and the expression of IL-8, IL-10, TH, β3AR, and eNOS in the myocardium was determined by using Western blot. RESULTS: Compared with the sham group, a marked myocardial infarction was found in the left ventricle tissue, accompanied with disordered arrangement of myocardial fibers and higher degree of inflammatory cell infiltration, and increased expression of IL-8, TH, β3AR and eNOS in the myocardium in the model group (P0.05). After EA intervention and in comparison with the model group, the myocardial infarct size was significantly reduced (P<0.01), the severity of inflammatory cell infiltration and disordered arrangement of myocardial fibers were relieved, and the expression of IL-10 and eNOS proteins were significantly up-regulated (P<0.05), and the markedly up-regulated expression of IL-8, TH, and β3AR were significantly suppressed in the EA group (P<0.01)．. CONCLUSION: EA intervention can reduce the myocardial infarct size (protective effect) in MI rats possibly by reducing inflammatory reaction and sympathetic nerve remodeling.
Résumé
Fibroblast growth factor 21 (FGF21) is regarded as an important metabolic regulator playing a therapeutic role in diabetes and its complications.Recently, growing evidence showed that heart is a key target as well as a source of FGF21 which is involved in heart development and also induces beneficial effects in cardiovascular diseases.Strong evidences showed that the development of cardiovascular diseases including atherosclerosis, atherosclerosis, coronary heart disease, myocardial ischemia, cardiac hypertrophy, and diabetic cardiomyopathy is associated with increased serum FGF21 levels which was regarded as a compensatory response to induced cardiac protection.This review tries to illuminate the underlying relationship between FGF21 and cardiovascular diseases and the possible mechanisms.
Résumé
A total of 10 adult patients suffering from early schistosomiasis japonica at the Bethany Hospital, Tacloban City with daily injections of Sodium Antimony Dimethylcysteine Tartrate (NaP) for 5 days at 400 mgs./day. Two had severe reactions consisting of nausea, vomiting and body weakness. Cardiac toxicity was observed in nine cases which developed reversible myocardial ischemic injury. A 100% cure rate from one to six months of stool follow-up after treatment was obtained. The exact value of this drug for mass treatment however, will depend on further evaluation of its toxicity and efficacy with a different dosage and/or schedule between injections.(Auth. Abs.)
