早发型与晚发型重症肌无力患者的临床特点分析

objective To compare the clinical characteristics of early-onset and late-onset myasthenia gravis(MG).Methods A total of 819 MG patients admitted in our department during the sanle period were reviewed retrospectively.The patients with MG were divided into two groups by the age of onset, which were the early-onset MG(＜49 years)and late-onset MG(≥50 years).Several clinical features were compared in the two groups including the percentage, initial symptoms, MG types,the positive rates of neostigmine test and repetitive nerve stimulation, thyroid function and thymie abnormalities. Results The more common onset age of MG was 0-49 years(early-onset).In both groups the male and female ratio was presented as the most common type in both groups(41.51%and 51.37% respectively in early-onset and late-onset groups).Type Ⅰ was more common in early-onset group while typeⅡB Was more common in lateonset group(P＜0.05).There Was no significant difference in the positive rates of neostigmine test and repetitive nerve stimulation between the two groups.The thyroid function alnormality ratio was higher in early-onset group. Hyperplastic thymus was common in early-onset group(67.57%)while both hyperplastic thymus and thymoma were common in late-onset group(48.68% and 47.37%).Conclusions The clinical characteristics of early-onset and late-onset myasthenia gravis(MG)Was different in MG type, the positive rate of thyroid function abnormalities and thymic pathologic type.

重症肌无力伴发甲状腺异常的临床分析

Objective To analyze the clinical characteristics of myasthenia gravis(MG) associated with thyroid abnormalities.Methods A total of 300 MG patients admitted to the department of neurology from July 2008 to September 2009 were reviewed retrospectively.Based on the thyroid function and abnormality of thyroid related antibodies (thyroglobulin antibody and peroxidase antibody), the patients with MG were divided into two groups (260 cases without thyroid disease and 40 cases with thyroid abnormalities).The different clinical features, the relationship between the antithyroid antibodies and antiacetylcholine receptor antibody (AChRAb) and the distribution of T cell subsets between the two groups were compared.Results ( 1 ) Among the 300 MG patients, 13.3% of them was accompanied with thyroid disease and the most common abnormality was positive thyroid antibody.(2) Between the groups of MG with and without thyroid abnormalities, no significant differences on the sex percentage, age of onset, duration of disease, clinical classification and thymic abnormalities were found ( P ＞ 0.05 ).( 3 ) The blood levels of AChRAb in postsynaptic membrane in the thyroid antibody-positive patients were 1.15 ± 0.11, being much higher than those in the antibody-negative patients ( 1.01 ±0.11 ).(4) The percentage of CD8+ T cells was significantly decreased [(21.63 ±5.17)% vs (24.28 ±5.79)%] and the ratio of CD4+/CD8+ T cells was increased (2.10 ± 0.67 vs 1.81 ± 0.61, P ＜ 0.05 ) in the group of MG with thyroid abnormality as compared with the group of MG with normal thyroid.Conclusion In MG patients the incidence positive thyroid related antibodies was much higher than that of other thyroid abnormalities.It is suggested that there are higher levels of AChRAb in MG coexisting with positive thyroid antibodies and more abnormalities of T lymphocyte subset distribution in MG patients with thyroid disease.

Objective To explore the variation tendency of serum thyroid hormone level in the elderly aged over 80 years.Methods The 602 healthy volunteers were divided into 3 groups by age:young group (20-59 years of age,n= 226),elderly group (60-79 years of age,n= 195),and advanced age group (80-102 years of age,n=181).Fasting blood of all persons was harvested,then the levels of serum total triiodothyroxine (TT3),total thyroxine (TT4),free tri-iodothyronine (FT3),free thyroxine (FT4),thyroid-stimulating hormone (TSH) and reverse tri-iodothyronine (rT3) were determined by chemistry luminescence technique and radioimmunoassay.Statistical analysis was made by the software SPSS 13.0.Results The levels of serum FT3 and TT3 were lower in elderly group than in young group (t=2.793,3.627,P=0.005,0.000).There were significant differences in the levels of serum TT3,TT4,FT3,TSH and rT3 between young group and advanced-age group (t =10.930,6.065,15.398,- 2.933,- 5.643,all P = 0.000),also between elderly group and advanced-age group (t= 8.382,4.298,11.573,-3.383,-5.148,all P＜0.001).The levels of serum FT3,TT3 and TT4 were negatively correlated with age (r=- 0.51,-0.39 and -0.25,respectively,all P＜0.01).And the levels of serum rT3 and TSH showed positive relationships with age (r=0.32,0.12,all P＜0.01).There were no relationships between the level of serum FT4 and age.The positive rate of serum TT3,TT4,FT3,FT4,TSH and rT3 concentration beyond the reference value was 0,0,13.8%,0,6.6% and 21% in advanced-age group,respectively.Conclusions The levels of serum thyroid hormone and thyroid-stimulating hormone change with age.The levels of FT3,rT3 and TSH change obviously in the elderly aged over 80 years.It could reduce the false positive rate in clinical practice if normal reference range for serum thyroid hormone levels in different aged elderly is established.

老年胃食管反流病患者临床特征分析

Objective To analyze clinical characteristics of gastroesophageal reflux disease(GERD) in aged patients for improvement of diagnosis and treatemcnt. Methods The reflux disease questionnaire was performed in patients diagnosed as GERD based on Montreal definition and classification as well as Rome Ⅲ criteria.All patients were divided into elderly group (≥65 years) and control group(＜65 years). The incidence of hita[ hernia (HH), the frequencies of esophagitis (based on Los Angeles classification), clinical features, and quality of life were compared between two groups. Results There was no difference between two groups in male/female ratio and morbidity of HH(P＞0.05). In comparison with control group, the frequency of esophagitis graded as LC or LD increased and extra-esophageal symptoms were higher in elderly group (P＜ 0.05), but the lower typical symptoms (heartburn and regurgitation) were seen in the elderly group(P＜0.05). The scores of role physical, bodily pain and role emotional were higher in elderly group than those in control group (P＜0.05). There was no significant differences between two groups in physical function, vitality,social functioning, mental health, and general health. Conclusion The elderly GERD patients often have lower score of typical reflux symptoms (heartburn and regurgitation) and high incidence of severer esophagitis, but their quality of life is not significantly influenced.

State of knowledge of helminth fauna of freshwater fishes of Poland

A total 89 fish and lamprey species has been recorded from Polish freshwater habitats. Twenty-seven of them (30.3%) have not been surveyed for parasitic helminthes. Some of the latter fishes are either rare or not easily accessible. Other live only in specific habitats in scattered localities. An important obstacle for studying parasite faunas of some fishes may be their status on an endangered species. Among the non-surveyed fishes, are those which have been relatively recently introduced to Poland or migrated there on their own. The present paper attempts to review all hitherto not studied helminthologically fish species, their habitats, localities and current protection status.
