信号转导和转录活化因子3与系统性红斑狼疮的研究进展

系统性红斑狼疮(SLE)是以全身免疫异常而致多器官受累为特征的疾病,病理表现为自身抗体产生和免疫复合物沉积。SLE发病机制复杂,为多种基因和环境因素相互作用的结果。这种相互作用激活T细胞,活化的T细胞反过来再激活B细胞,导致过多的自身抗体产生。T细胞和B细胞的功能是通过细胞内信号转导来实现的。信号转导和转录活化因子3(signal     

Effect of Tai Chi on Muscle Strength of the Lower Extremities in the Elderly

Objective: Aging is associated with a progressive decline in muscle strength, muscle mass and impaired physical function, which reduces mobility and impairs quality of life in the elderly population. The 6–12 months of exercise can enhance the muscle strength, but these improvements can only be maintained for a short period. In this study, we investigated the effects of long-term Tai Chi(TC) exercise on muscle strength of lower extremities. Methods: A cross-sectional study was conducted in 205 long-term TC practitioners(age: 60–89 years) and 205 age and gentle matched controls who did not practice TC. Each of the activity group was further divided into three distinct age groups: G1, 60–69 years; G2, 70–79 years; and G3, 80–89 years. Hand-held dynamometery was used to measure the maximum isometric strength of iliopsoas, quadriceps femoris, tibialis anterior and hamstrings in both sides of the participants. Unpaired t tests were performed to compare the difference of strength between the TC and non-Tai Chi(NTC) groups. Multivariate analysis of variance(MANOVA) was used to compare the lower muscle strengths among the different age groups in the TC and NTC groups. Pearson's correlations were used to quantify the linear relationship between the months of TC practice and lower limbs muscle strength. Results: The inter-rater reliabilities of iliopsoas, quadriceps femoris, tibialis anterior and hamstrings were intraclass correlation coefficient(ICC)(1,1) = 0.895(0.862–0.920), ICC(2,2) = 0.905(0.874–0.928), ICC(3,3) = 0.922(0.898–0.941) and ICC(4,4) = 0.930(0.908–0.947). The strength of the muscles in the TC group did not differ among different age groups(P0.05). The strength of iliopsoas, quadriceps femoris, tibialis anterior and hamstrings in TC group was higher than that in the NTC group(P0.05). A correlation between muscle strength and extension of the exercise period was positive(P0.05). Conclusion: Results shed light on the orientation and magnitude of long-term TC in preventing muscle strength loss with aging. TC might be a good form to slow down the trend of age-related decline in muscle strength in community-dwelling population.
