ABSTRACT
To explore the clinical efficacy and possible mechanism of Tai Ji Quan for post-stroke depression (PSD), literature related to Tai Ji Quan and PSD were retrieved from China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full- text Database (Wanfang), Chongqing VIP Database (CQVIP), China Biology Medicine Disc (CBM), and PubMed, screened and then summarized. The results showed that Tai Ji Quan could effectively improve the depression and quality of life of stroke patients, and there were differences in the clinical efficacy among different training programs. Tai Ji Quan has the characteristics of "regulating mind", "regulating breath", and "regulating body". It may achieve the effect of "combined physique-spirit treatment" by improving social psychology, increasing the level of neurotrophin, regulating neuroendocrine, reducing inflammatory factors, and regulating neural circuits.
ABSTRACT
Objective: To systematically evaluate the effects of different forms of traditional Chinese health-preservation exercises on osteoporosis (OP) using network meta-analysis.Methods: A systematic search on Excerpta Medica Database (EMBASE), Springer Link, Allied and Complementary Medicine Database (AMED), PubMed, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang) and Chongqing VIP Database (CQVIP) targeted the randomized controlled trials (RCTs) studying traditional Chinese exercises for OP published up to January 2020. Cochrane handbook was adopted to estimate the publication bias in the included studies, and statistical analysis was performed using Stata 14.0 and GeMTC 0.14.3 when data were extracted. Results: Fifty RCTs were included in the network meta-analysis, comprising a total of 4505 OP patients. The network meta-analysis showed that in terms of visual analog scale (VAS) for pain, Tai Ji Quan (Tai Chi) was the most efficacious, followed by Yi Jin Jing (Sinew-transforming Qigong Exercises), Ba Duan Jin (Eight-sectioned Exercise), Wu Qin Xi (Five-animal Exercises), sports training, drug and blank control; in terms of bone mineral density (BMD) of femoral neck, Yi Jin Jing was the most efficacious, followed by Wu Qin Xi, Ba Duan Jin, Tai Ji Quan, sports training, blank control and drug; regarding the lumbar BMD, it was Yi Jin Jing, Tai Ji Quan, Ba Duan Jin, Wu Qin Xi, sports training, blank control and drug in the descending order of efficacy; in terms of serum alkaline phosphatase, it was Yi Jin Jing, Tai Ji Quan, sports training, Wu Qin Xi, Ba Duan Jin, drug and blank control in the descending order of efficacy. Conclusion: The evidence to date suggests that the first choice for OP amongst the traditional Chinese exercises should be Yi Jin Jing, which can not only reduce the subjective pain, but also promote bone formation and increase BMD, though this conclusion requires more high-quality large-scale RCTs for further proof.
ABSTRACT
Objective:To evaluate the effects of Tai Ji Quan exercise on aerobic capacities and cognitive function in middle-aged and elderly people. Methods:From June, 2018 to July, 2019, 60 middle-aged and elderly subjects were divided into Tai Ji Quan group (n = 13), meditation group (n = 14), aerobics group (n = 17) and sedentary group (n = 16). Before and 24 weeks after exercise, the body mass index (BMI), the VO2max, and the amplitude and latency of P3b and reaction time of P300 wave were observed. Results:After exercise, there was significant difference in BMI among groups (F = 7.568, P < 0.001); the VO2max was higher in aerobics group than in Tai Ji Quan group and the sedentary group (t > 3.039, P < 0.01), as well as in Tai Ji Quan group and the meditation group than in the sedentary group (t > 2.152, P < 0.05); the amplitude of P3b was lower in the sedentary group than in other groups (t > 2.667, P < 0.01); the P3b latency tended to be longer in the sedentary group than in other groups, but no significant difference was observed among groups (F = 0.419, P = 0.740); the reaction time tended to be shorter in Tai Ji Quan group than in other groups, but no significant difference was observed among groups (F = 1.804, P > 0.05). Conclusion:Tai Ji Quan exercise may improve aerobic capacities, and benefit the cognitive function.
ABSTRACT
Objective:To explore the effect of Tai Ji Quan in the progress of rehabilitation training for elderly patients with heart failure after myocardial infarction. Methods:From January, 2017 to June, 2019, a total of 200 elderly patients with heart failure after myocardial infarction were divided into control group (n = 100) and experimental group (n = 100). The control group received routine medicine, and the experimental group received Tai Ji Quan exercise in addition. After 24-week treatment, their cardiac functional grading, plasma levels of brain natriuretic peptide (BNP) and aldosterone (ALD), six minutes walking distance (6MWD), left ventricular ejection fractions (LVEF), quality of life, and readmission rate and mortality rate were compared. Results:After treatment, the cardiac function was better in the experimental group than in the control group (χ2 > 5.143, P < 0.05); the plasma levels of BNP and ALD, 6MWD, LVEF and quality of life significantly improved (|t| > 9.883, P < 0.001), and were better in the experimental group than in the control group (|t| > 4.023, P < 0.001). The readmission rate and mortality rate were lower in the experimental group than in the control group, but no significant difference was found (P > 0.05). Conclusion:Tai Ji Quan exercise could improve the cardiac function, exercise tolerance and quality of life of the elderly patients with heart failure after myocardial infarction.
ABSTRACT
Objective To explore the efficacy of Tai Ji Quan on the elders with mild cognitive impairment (MCI). Methods From June to October, 2015, 108 old people with MCI were divided into control group (n=54) and intervention group (n=54). Both groups studied rele-vant knowledge about MCI and received handbooks. The excise of Tai Ji Quan was regularly conducted in the intervention group at least for-ty minutes a time and four times per week for three months. They were assessed with the Peking Union Medical College Version of Montre-al Cognitive Assessment (MoCA-P) before and after intervention. Results There was no significant difference in the scores of MoCA-P be-tween two groups before intervention (Z0.05). After intervention, the total scores of MoCA-P, and the scores of visual space func-tion and long delayed recall were higher in the intervention group than in the control group (Z>3.425, P<0.01). Conclusion Tai Ji Quan can effectively improve the cognitive function, especially memory and executive function, in the elderly with MCI.
ABSTRACT
Serum hormone contents have been determined among three groups: group A—51 males aged 60—80 with 10 years or more of experience in Tai Ji Quan; group B—47 males of the same age used as control; group C—17 ordinary adults aged below 50. The results are as follows:The indicators of the thyroid axis and the gonad axis are improved in group A as compared with those in group B. TSH, FSH and LH at the pituitary level in group A are significantly higher than those in group B, suggesting that the effect of Tai Ji Quan in helping keep fit and prevent diseases is brought about by the regulatory action of the neuro-endocrine center on the associated glands and consequently by invigorated systemic metabolism through the action of the endocrine hormones. It is a recommendable physical exercise intended as a means of acquiring good health and a longer life.
