Effect observation and literature review of enzyme replacement therapy in late-onset Pompe disease / 中华神经科杂志

Objective:To analyze the efficacy and safety of enzyme therapy in late-onset Pompe disease (LOPD) patients, so as to provide reference for the treatment and prognosis of LOPD.Methods:The effect of α-glucosidase (GAA) on a patient diagnosed with LOPD in the Affiliated Hospital of Jining Medical University was observed and analyzed. Besides, literature related to enzyme therapy in LOPD patients were searched in PubMed, Web of Science, Medline databases. Twenty-one studies containing clinical data from 910 LOPD patients related to enzyme therapy were finally included for analysis.Results:The patient developed muscle weakness since he was 16 years old. The GAA activity in peripheral blood was 0. Electromyography suggested myogenic lesions in both lower extremities. Compound heterozygous mutations of GAA gene were found by next- generation sequencing. Muscle biopsy revealed characteristic vacuolar changes. After eight years of diagnosis, the patient was given enzyme therapy for 18.5 months, 20 times in total. The symptoms of muscle weakness were slightly improved in the early stages of treatment without obvious adverse reactions. Most of the 910 LOPD patients were stabilized or had improved muscular and (or) respiratory function following treatment with GAA.Conclusion:GAA treatment is effective and well tolerated. In patients with advanced severe LOPD, enzyme replacement therapy remains effective even years after onset.

Effects of phytoestrogens resveratrol and phloretin on contractile response of aortic strips in rabbits / 中国药理学与毒理学杂志

AIM To investigate whether the relaxation characteristics of phytoestrogens resveratrol and phloretin on contractile response of aortic strips are similar to that of estrogen and the mechanisms underground. METHODS Aortic strips from rabbits were suspended in organ baths containing Krebs solution, and then isometric tension was measured. RESULTS Resveratrol and phloretin inhibited the contractile responses to norepinephrine (NE), KCl and CaCl2, shifted their concentration-response curves rightward with pD2′ values of 2.89, 3.34, 3.37 for resveratrol and 3.23, 3.52, 3.77 for phloretin respectively. Also both of them concentration-dependently relaxed KCl-precontracted aortic strip. The relaxing response of resveratrol but not of phloretin in aortic strip was significantly reduced by removal of endothelium or incubation with Nω-L-nitro-arginine and methylthioninium chloride, however both their relaxant effects were not affected by indometacin and propranolol. In Ca2+-free Krebs solution containing 0.01 mmol·L-1 EGTA, resveratrol and phloretin inhibited NE-induced contraction which was caused by Ca2+ release from intracellular store, but did not affect the contraction which was induced by Ca2+ influx. CONCLUSION Resveratrol and phloretin can induce vasorelaxations which may relate to inhibition of Ca2+ influx through potential-dependent calcium channels and Ca2+ release from intracellular stores, and the relaxing response of resveratrol is endothelium-dependent in part, but of phloretin is not endothelium-dependent.

Actions of Immature Orange Fruit and Dried Tangerine Peel on the Tension of Isolated Aortic Muscle Strips / 中成药

Objective: To study the effects of immature orange fruit(IOF) and dried tangerine peel(DTP) on the resting tension of isolated aortic muscle strips in rabbits and their mechanisms. Methods: The organ-bath was used to observe the response of aortic strip to IOF and DTP. Results: IOF and DTP dose-dependently increased the tension of aortic strip, and the action of IOF was more significant than that of the same concentration DTP. 10 -7 mol/L phentolamine, 10 -5 mol/L verapamil or incubation with Ca 2+ -free Krebs solution could block the effects of IOF and DTP partly, but 10 -6 mol/L diphenhydramine could not. In endothelium-removed aortic strips, the effects of IOF and DTP decreased after treatment with 10 -7 mol/L atropine. Conclusions: IOF and DTP can contract vascular smooth muscle, which probably contribute to ? adrenergic receptor, cholinergic M receptor on membrane of vascular smooth muscle partly, and is dependent Ca 2+ influx through verapamil-sensitive Ca 2+ channels, but is not related to H 1 histamine receptor.

Effects of genistein on contractility of isolated left ventricular papillary muscles in guinea pig / 中国药理学通报

Aim To study the effect of genistein on contractility of isolated papillary muscles in guinea pig and its mechanisms.Methods Isolated guinea pig papillary muscles were suspended in organ baths containing KH solution,and the effect of genistein on contractility of myocardium was observed after an equilibration period.Results Genistein and isoprenaline hydrochloride showed positive inotropic effects on contractility of myocardium in a dose-dependent manner(1～100 ?mol?L~(-1)) Propranolol(1 ?mol?L~(-1)) and verapamil hydrochloride(0.5 ?mol?L~(-1)) attenuated the positive inotropic effect of isoprenaline hydrochloride(2 ?mol?L~(-1)),but did not change the effect of genistein(100 ?mol?L~(-1)).Furthermore,the enhancement of the contractility induced by elevation of extracellular Ca~(2+) concentration in papillary muscles did not show any change after pretreatment with genistein(1,10 ?mol?L~(-1)).Finally,the positive inotropic effect of genistein was attenuated partially by tamoxifen(1 ?mol?L~(-1)),however,was not influenced by sodium orthovanadate(1 ?mol?L~(-1)).Conclusions Genistein has the positive inotropic effect on guinea pig papillary muscles,which is not related to the activation of Ca~(2+) channel on cell membrane,? adrenoceptor and tyrosine kinase pathway,but this effect may involve in uptake and utilization of sarcoplasmic reticulum Ca~(2+).
