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.

Purpose:To study the clinical significance of a tumor marker, serum CA153(sCA153), in the differential diagnosis between benign and malignant lung diseases, and in the evolution of lung cancer. Methods:124 serum samples was collected from 124 in-ward patients. Among them, 74 patients had lung cancer, and 50 patients had benign lung diseases (BLD). The concentrations of sCA153 and serum CEA (sCEA) were determined by immunoradiometric assay method.Results:In the lung cancer group, the total positive rate of sCA153 was 62.68%, which was evidently higher than that in BLD group(P0.9). In the different cell types of lung cancer patients, the concentration of sCA153 in lung adenocarcinoma patients was increased much more than that of other lung cancer groups (P
