Objective:To study the influence of “Warming Yang and Nourishing Qi”Acupuncture in the expression levels of acetylcholine receptor protein (AchR)in gastrocnemius neuromuscular junction (NMJ)of the rats with experimental autoimmune myasthenia gravis (EAMG),and to clarify the mechanism of “Warming Yang and Nourishing Qi”Acupucture in the treatment myasthenia gravis (MG).Methods:The female Lewis rats were used to establish the EAMG rat models immuned with AchRα1 129-145 polypeptide fragments.30 EAMG rats were selected randomly and divided into model control group, drug control group, and acupuncture treatment group (n=10),and another 10 rats purchased at the same period were used as blank control group.The rats in drug control group were treated with 1 8.5 mg · kg-1 · d-1 pyridostigmine by gavage. And the rats in acupuncture treatment group were treated with irritating by“Warming Yang and Nourishing Qi”Acupuncture.The rats in blank control group and model control group were not treated .The Lennon symptom scores of the rats in various groups were recorded.After treatment,the tissues of gastrocnemius NMJ of the rats were taken,and the AchR protein expression levels in NMJ of the rats in various groups were detected by Western blotting method. Results:Compared with blank control group,after successfully modelling,the Lennon symptom scores of the rats in model control group, drug control group and acupuncture treatment group before treatment were significantly increased (P<0.01).Compared with model control group,the Lennon symptom scores of the rats in drug control group and acupuncture treatment group after two treatment course were significantly increased (P<0.01 ). Compared with blank control group, the AchR protein expression level in gastronemus NMJ of the rats in model control group was significantly decreased (P<0.01). Compared with model control group, the AchR protein expression levels in gastronemus NMJ of the rats in acupuncture treatment group and drug control group after treatment were significantly increased (P<0.01).Conclusion:“Warming Yang and Nourishing Qi”Acupuncture has good therapeutic effect on the EAMG through increasing the NMJ AchR protein expression level of the EAMG rats.

Objective To assess the clinical application value of vector flow mapping (VFM) in evaluating the left ventricular diastolic function in hypertensive patients with different left ventricular geometric patterns.Methods One hundred and sixty-nine patients with hypertension and 50 healthy volunteers were enrolled.Hypertensive patients were divided into four groups with different ventricular configurations according to ASE guide line in 2005:normal geometry group,concentric remodeling group,concentric hypertrophy group and eccentric hypertrophy group.The quantitative parameters,including average energy loss(aEL) and circulation were measured.Difference was evaluated among five groups at apical,mid and basal segments and at different periods.The correlationship was analyzed between aEL,circulation and E/e',respectively.Results ① Compared to control group,aEL was higher in four hypertension groups at three segments of atrial systole(P ＜0.05).aEL in eccentric hypertrophy group was higher than those in control group,normal geometry group or concentric remodeling group at apical and mid segments of atrial systole,and higher than those in other hypertensive groups at basal segment (P ＜ 0.05).In four hypertension groups,circulations in rapid filling phase of anterior mitral valve were lower than that in control group,but circulations in slow filling phase of posterior mitral valve were higher than that in control group(P ＜0.05).The circulation in slow filling phase of posterior mitral valve in concentric remodeling group was higher than that in normal geometry group,and that in eccentric hypertrophy group was higher than those in normal geometry group and concentric remodeling group(P ＜0.05).②When intra-group comparison,aEL were different in different segments of same phase or at different phases of same segment(P ＜0.05).③aEL had a good correlation with E/e'at basal segment of atrial systole in four hypertension groups(r =0.66,P ＜0.01).Conclusions VFM can be utilized to analyze left ventricular hemodynamics features of hypertensive patients with different left ventricular geometric patterns,it may be a good supplement for assessing cardiac diastolic function and reflect the extent of damage.
