Objective To explore the correlation of β2-adrenergic receptor (β2-AR) polymorphisms (Arg16Gly) with early onset Myasthenia Gravis (MG). Methods Forty-eight with age less than 40 years at disease onset were divided into three groups:normal thymus (13 cases), thymic hyperplasia (22 cases) and thymoma (7 cases) groups according to the thymus histology. These patients were further divided into different subgroups including female (31 cases) and male groups (17 cases) based on the gender, OMG (29 cases) and GMG (19 cases) groups according to the symptom of disease onset and groups associated with (10 cases) or without (33cases) other autoimmune diseases Or with unknown causes (5 cases). The genotypes ofβ2-AR in 48 early onset MG were determined by gene sequencing. Results Arg/Arg was more common in early MG patient with normal thymus ( 53.8%)and thymic hyperplasia(54.6%)whereas Arg/Gly was more common in thymus group(71.4%). The difference in distribution of the genotypes between the three groups was not statis?tically significant (χ2=5.657,P=0.226). Arg/Arg was more common in early female MG patient (58.1%) and Arg/Gly was more common in male MG patients (58.8%). The difference in distribution of the genotypes between the two groups was
statistically significant (χ2=6.064,P=0.048). Arg/Arg was more common in early OMG patient (48.3%). Arg/Arg(42.1%) and Arg/Gly(47.4%) were equal common in GMG patients. The difference in distribution of the genotypes between the two groups was statistically significant ( χ2=1.623,P=0.444). Arg/Arg was more common in early MG patient associated with other autoimmune diseases (80.0%). Arg/Gly was more common in MG patients without other autoimmune diseases (39.4%). The difference in distribution of the genotypes between the three groups was statistically significant (χ2=6.394, P=0.041). Conclusionβ2-AR gene polymorphism in position 16 is associated with gender and other autoimmune diseas?es in patients with early onset of MG.

Objective To explore the correlation of β2-adrenergic receptor (β2-AR)polymorphisms (Arg16Gly) with the prognosis of myasthenia gravis (MG) complicated with other autoimmune diseases.Methods Among the 75 MG patients in analysis,17 cases were complicated with other autoimmune diseases (AIDMG),58 cases without other autoimmune diseases (NAIDMG).MG patients,AIDMG patients,NAIDMG patients were separately divided into recurrence groups and nonrecurrence groups according to the progression at 2 years after onset.The genotypes of β2-AR in 75 MG patients were determined by gene sequecing.Results The frequencies of three genotypes (Arg/Arg,Arg/Gly and Gly/Gly) in position 16 were 30.8％,50.0％,19.2％ in recurrence MG group and 42.9％,38.8％,18.3％ in non-recurrence MG group respectively.The difference in distribution of the genotypes between recurrence MG group and non-recurrence MG group was not statistically significant (x2 =1.150,P=0.563).The frequencies of Arg and Gly allele were 55.8％ and 44.2％ in recurrence MG group,and 62.2％ and 37.8％ in non-recurrence MG group.The difference in distribution of the alleles between the two groups was not statistically significant.The frequencies of 3 genotypes in position 16 were 27.3％,63.6％ and 9.1％ in recurrence AIDMG group and 100.0％,0,0 in non-recurrence AIDMG group,respectively.The frequencies of Arg and Gly allele were 59.1％,40.9％ in recurrence AIDMG group,and 100.0％,0 in non-recurrence AIDMG group.The difference in distribution of the genotypes between recurrence AIDMG group and non-recurrence AIDMG group was statistically significant (P =0.009).There also was significant difference in distribution of alleles between recurrence and non-recurrence AIDMG groups (x2 =6.676,P =0.010).The frequencies of 3 genotypes in position 16 were 33.3％,40.0％ and 26.7％in recurrence NAIDMG group and 34.9％,44.2％,20.9％ in non-recurrence NAIDMG group,respectively.The frequencies of Arg and Gly allele were 53.3％,46.7％ in recurrence NAIDMG group,and 57.0％,43.0％ in non-recurrence NAIDMG group.There was no significant difference in distribution of genotypes or alleles between recurrence and non-recurrence NAIDMG groups.Conclusion β2-AR gene polymorphism in position 16 may predict the prognosis of AIDMG,and there is no correlation between the polymorphism in position 16 of β2-AR and the prognosis of MG and NAIDMG.

Objective To investigate the association of glucocorticoid receptor (GR) polymorphisms (BclI)with the prognosis of myasthenia gravis (MG).Methods We totally enrolled 74 patients diagnosed as MG from the Department of Neurology,Beijing Shijitan Hospital between 2002 and 2014.Of them,54 patients started with ocular MG and 20 patients started with general MG.MG patients were divided into recurrence group and non-recurrence group according to the progression at two years after onset.Patients with simple ocular symptom at disease onset were further divided into generalized MG (GMG) group and single ocular MG (OMG) group according to disease progression or not.The GMG group was divided into two groups (≤6 months,7-24 months) according to the progression time of generalization.The GMG group was further divided into three groups (limbs,throat,both limbs and throat) according to the first symptom of generalization.The genotypes of GR were determined by polymerase chain reaction and nucleotide sequence determination.Results The frequencies of three genotypes (GG,CG,CC) in BclI were 57.7％,34.6％,7.7％ in recurrence MG and 64.6％,31.3％,4.1％ in non-recurrence MG respectively.The difference in distribution of the genotypes between the two groups was not statistically significant (x2 =0.570,P =0.750).The frequencies of G and C allele were 75.0％ and 25.0％ in recurrence MG,and 80.2％ and 19.8％ in non-recurrence MG.The difference in distribution of the alleles between the two groups was not statistically significant (x2 =0.540,P =0.462).The frequencies of three genotypes GG,GC and CC were 55.9％,35.3％,8.8％ in GMG and 2/6,4/6,0/6 in OMG respectively.The frequencies of G and C allele were 73.5％ and 26.5 ％ in GMG,and 8/12,4/12 in OMG.The difference in distribution of the genotypes and alleles between the two groups was not statistically significant (x2 =2.278,P =0.320;x2 =0.241,P =0.624).The frequencies of three genotypes GG,GC,CC were respectively 61.9％,28.6％,9.5％ and 3/6,3/6,0/6 in ≤6 months,7-24 months of GMG group.The frequencies of G and C allele were 76.2％,23.8％ and 9/12,3/12 in the two groups.The difference in distribution of the genotypes and alleles between two of the three groups was not statistically significant (x2 =1.326,P =0.515;x2 =0.007,P =0.932).The frequencies of three genotypes GG,GC and CC were respectively 2/8,4/8,2/8;11/13,2/13,0/13 and 3/6,3/6,0/6 in limbs,throat,both limbs and throat of GMG group.The frequencies of G and C alleles were 8/16,8/16;92.3％,7.7％ and 9/12,3/12 in the three groups.The difference in distribution of the genotypes and alleles between two of the three groups was statistically significant (x2 =8.813,P =0.028;x2 =9.706,P =0.008).The genotype frequencies in every group were all in Hardy-Weinberg equilibrium.Conclusions BclI polymorphism may predict the first generalized symptom of OMG.BclI polymorphisms of GR might have no relationship with the recurrence of MG,generalization and generalized time of OMG during the first two years after MG onset.

Objective To investigate the influence of injection carthamus tinctorius D. (1C) on the expression of intercellular adhesion molecule-1(ICAM-1) during the ischemia-reperfusion injury of lung (LIRI) in rabbits and its potential mechanism. Method Single lung ischemia-reperfusion animal model was induced in rabbits. A total of 30 Japanese white rabbits were randomly divided into sham-operation group (S group, n =10), ischemia-reperfusion group (I/R group, re = 10) and ischemia-reperfusion plus 1C group (1C group, n = 10) .The rabbits of 1C group received 1C 2.0 ml/kg injected intravenously just at 20 min before ligation of artery involved and the same dose of 1C instantly at the initiation of reperfusion. Malondialdehyde (MDA) , superoxide dismutase (SOD) and xanthine oxidase(XO) in serum were measured. The lung tissue was sampled and assayed wet/dry weight ratio (W/D), contents of myeloperoxidase (MPO) at the end of the experiment, and ultrastructure changes were observed under electron microscope. The expression of ICAM-1 was measured by using immunohistochemistry(IHC) . snd one-way ANOVA was used for statistical analysis. Results In I/R group, serum XO and MDA increased and SOD decreased, whereas the same pattern of changes but less magnitude happened in 1C group ( P < 0.01). The values of W/D and MPO were much higher in I/R group, but lower in 1C group. Under electron microscope, the ultrastructure of lung tissue showed pathological changes in the rabbits of I/R group,and these changes were greatly attenuated in the rabbits of 1C group . The IHC showed that ICAM - 1 in lung tissue of I / R group was (2.94±0.48) which was significantly higher than that of 1C group(1.75 (P < 0.01). Conclusions Injection Carthamus tinctorius D. may meliorate the ischemia-reperfusion injury of lung by way of suppressing the expression of ICAM-1, inhibiting neutrophil aggregation, lowering oxygen free radical level and decreasing lipid peroxidation.
