RESUMO

Exercise has shown to have beneficial effects on cognition in older adults. The purpose of this study was to investigate the cortical hemodynamic responses during the word-color Stroop test (WCST) prior and after acute walking and Tai Chi exercise by functional near-infrared spectroscopy (fNIRS). Twenty participants (9 males, mean age 62.8 ± 5.2), first underwent a baseline WCST test, after which they took three WCST tests in a randomized order, (a) after sitting rest (control), (b) after 6 minutes performing Tai Chi Quan, and (c) after a bout of 6 minutes brisk walking. During these four WCST tests cortical hemodynamic changes in the prefrontal area were monitored with fNIRS. Both brisk walking and Tai Chi enhanced hemodynamic activity during the Stroop incongruent tasks, leading to improved cognitive performance (quicker reaction time). Brisk walking induced a greater hemodynamic activity in the right dorsolateral prefrontal cortex (DLPFC) and ventrolateral prefrontal cortex (VLPFC) area, whereas Tai Chi induced a greater bilateral hemodynamic activity in the DLPFC and VLPFC areas. The present study provided empirical evidence of enhanced hemodynamic response in task- specific regions of the brain that can be achieved by a mere six minutes of brisk walking or Tai Chi in older adults.

RESUMO

Introduction: Tai Chi standing meditation (Zhan Zhuang, also called pile standing) is characterized by meditation, deep breathing, and mental focus based on theories of traditional Chinese medicine. The purpose of the present study was to explore prefrontal cortical hemodynamics and the functional network organization associated with Tai Chi standing meditation by using functional near-infrared spectroscopy (fNIRS). Methods: Twenty-four channel fNIRS signals were recorded from 24 male Tai Chi Quan practitioners (54.71 ± 8.04 years) while standing at rest and standing during Tai Chi meditation. The general linear model and the SPM method were used to analyze the fNIRS signals. Pearson correlation was calculated to determine the functional connectivity between the prefrontal cortical sub-regions. The small world properties of the FC networks were then further analyzed based on graph theory. Results: During Tai Chi standing meditation, significantly higher concentrations of oxygenated hemoglobin were observed in bilateral dorsolateral prefrontal cortex (DLPFC), ventrolateral prefrontal cortex (VLPFC), frontal eye field (FEF), and pre-motor cortex (PMC) compared with the values measured during standing rest (p < 0.05). Simultaneously, significant decreases in deoxygenated hemoglobin concentration were observed in left VLPFC, right PMC and DLPFC during Tai Chi standing meditation than during standing rest (p < 0.05). Functional connectivity between the left and right PFC was also significantly stronger during the Tai Chi standing meditation (p < 0.05). The functional brain networks exhibited small-world architecture, and more network hubs located in DLPFC and VLPFC were identified during Tai Chi standing meditation than during standing rest. Discussion: These findings suggest that Tai Chi standing meditation introduces significant changes in the cortical blood flow and the brain functional network organization.

RESUMO

Objective: To study the effects of 12-week Taijiquan exercise on the microvascular reactivity of middle-aged and elderly patients with mild hypertension and to explore the mechanisms of microvascular reactivity. Methods: Thirty patients with mild hypertension were divided into exercise group (53.8±6.3 years old) and control group (52.6±7.5 years old). The number and gender ratio of the two groups were the same. The exercise group performed Tai Chi exercise for 12 weeks, and the control group maintained the original lifestyle and did not do other regular sports. The two groups of subjects were tested for microvascular reactivity, blood pressure, serum nitric oxide content, and nitric oxide synthase activity before exercise intervention, 6th week and 12th week, respectively. Results: There was no significant difference in the basic values of each index between the two groups of subjects before the test (P> 0.05). In the 6th week, the microvascular reactivity (blood flow increase rate), systolic blood pressure, diastolic blood pressure, nitric oxide content, nitric oxide synthase activity of the exercise group did not significantly change from the basic value (P>0.05). At the 12th week, the microvascular reactivity, nitric oxide content, c nitric oxide synthase activity were significantly higher than those of the base values and the control group (P<0.05), but the systolic blood pressure and diastolic blood pressure were significantly lower than those of the base values and control group (P<0.05). In the control group, there were no significant changes in the 6th and 12th week values of each index from the basic value (P>0.05). Conclusion: Twelve weeks of Taijiquan exercise can improve the microvascular reactivity of middle-aged hypertensive patients, reduce blood pressure, and increase the nitric oxide content and c nitric oxide synthase of patients. The increase of endogenous nitric oxide production is one of the biological mechanisms of Tai Chi exercise to improve the microvascular responsiveness of hypertension patients.

RESUMO

Huaganjian decoction (HGJD) was first recorded in the classic "Jing Yue Quan Shu" during the Ming dynasty, and it has been extensively applied in clinical practice to treat liver diseases for over 300 years in China. However, its bioactive constituents and relevant pharmacological mechanism are still unclear. In this study, a strategy integrating network analysis and metabolomics was applied to reveal mechanism of HGJD in treating cholestatic hepatic injury (CHI). Firstly, we observed the therapeutic effect of HGJD against CHI with an alpha-naphthylisothiocyanate (ANIT) induced CHI rat model. Then, we utilized UPLC-Q-Exactive MS/MS method to analyze the serum migrant compounds of HGJD in CHI rats. Based on these compounds, network analysis was conducted to screen for potential active components, and key signaling pathways interrelated to therapeutic effect of HGJD. Meanwhile, serum metabolomics was utilized to investigate the underlying metabolic mechanism of HGJD against CHI. Finally, the predicted key pathway was verified by western blot and biochemical analysis using rat liver tissue from in vivo efficacy experiment. Our results showed that HGJD significantly alleviated ANIT induced CHI. Totally, 31 compounds originated from HGJD have been identified in the serum sample. PI3K/Akt/Nrf2 signaling pathway related to GSH synthesis was demonstrated as one of the major pathways interrelated to therapeutic effect of HGJD against CHI. This research supplied a helpful strategy to determine the potential bioactive compounds and mechanism of traditional Chinese medicine.

RESUMO

BACKGROUND: Mild cognitive impairment (MCI) in the elderly is a health problem worldwide. Several clinical trials indicated that traditional Chinese medicine (TCM) exercise therapies can effectively improve MCI, such as Tai Ji, Baduan jin exercise, Liuzi jue, and finger exercise. However, there is still controversy over which therapy is the best for elderly MCI patients. In this study, we aimed to systematically evaluate and compare the effectiveness and safety of these 4 TCM exercise therapies in elderly patients with MCI. METHODS: The Web of Science, PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Clinical Trials, China National Knowledge Infrastructure, Wangfang database, and Chinese Biomedical Medicine will be comprehensively searched to collect all randomized controlled trials which included elderly participants with MCI receiving TCM exercise therapies through July 2020. Two reviewers will independently screen and evaluate each included study and extract the outcome indexes. ADDIS 1.16.8 software will be used for the network meta-analysis and STATA 14 software will be used for drawing network evidence plots and funnel plots. RESULTS: We will use the Bayesian statistical model to conduct a network meta-analysis to rank the effectiveness and safety of these 4 interventions, and use the GRADE approach to interpret the results. CONCLUSION: This network meta-analysis will find out the optimal treatment plan for MCI and provide evidence-based bias for clinical treatments decision-making.

RESUMO

We examined the effects of long-term exercise on age-related decline in static balance control through centre-of-pressure (CoP) measurements of four groups of participants: older controls, younger controls, older Tai Chi exercisers and older joggers. The participants stood quietly in a tandem stance on a force platform for 30 s with eyes open (EO) and eyes closed (EC). The older controls showed remarkably larger CoP and EC/EO ratios than younger controls and older Tai Chi exercisers. The EC/EO ratios of velocity in the mediolateral direction of older joggers were significantly smaller than those of older controls. Results suggest that the static balance of older controls showed a significant decline caused by age-related changes. Long-term Tai Chi and jogging, particularly the former, contributed to static balance control in older people. Older adults relied more on visual information in static postural control than young people. Tai Chi would be an ideal exercise for improving static balance in older people.

RESUMO

Objectives: For this paper, we aimed to investigate the effects of Tai Chi Chuan (TCC) versus the Core Stability Training (CST) program on neuromuscular function (NF) in the lower extremities among aging individuals who suffered from non-specific chronic lower back pain (NLBP). Regarding the design, during a 12-week intervention, a single-blinded randomized controlled trial was used to compare two intervention groups with a control group on the parameters of NF. Methods: Forty-three Chinese community-dwellers were randomly assigned into two intervention groups (three sessions per week, with each session lasting 60 min in TCC and CST) and a control group. The patient-based Visual Analogue Scale (VAS) was used to measure the level of perceived pain, while parameters of NF as primary outcomes were measured by the Biodex System 3 Isokinetic Dynamometer. Results: For the knee joint, we observed significant differences in the endurance of left extension at a speed of 60°/s: (1) between TCC and control groups (p < 0.01); (2) between CST and control groups (p < 0.01). For the ankle joint, significant differences between CST and control groups were observed on the peak torque of left dorsiflexion (p < 0.05) and the endurance of the left plantar flexion at a speed of 60°/s (p < 0.05). In addition, we observed a significant difference between TCC and control groups in the endurance of the right plantar flexion (p < 0.05). Conclusions: Chen-style TCC and CST were found to have protective effects on NF in aging individuals with NLBP, while alleviating non-specific chronic pain.

RESUMO

OBJECTIVE: This study aims to investigate the effect of t'ai chi exercise on hypertension in young and middle-aged in-service staff. METHODS: A total of 208 subjects with grade 1 hypertension were enrolled into this study. These subjects were randomly divided into two groups: research group and control group (n = 104, each). On the basis of general daily lifestyle intervention, subjects in the research group underwent 24-Style Simplified t'ai chi exercise for 3 months, whereas subjects in the control group underwent general daily lifestyle intervention. All subjects were followed up at the first and third month of intervention. The body mass index (BMI), blood pressure, blood lipid, and other indexes were measured before and after the intervention, and quality of life was evaluated. RESULTS: (1) In the research group, after 1 month of exercise, systolic blood pressure (SBP), heart rate (HR), triglyceride (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) significantly decreased (p < 0.05), while BMI, blood glucose (Glu), diastolic blood pressure (DBP), and pulse pressure (PP) did not significantly change. Furthermore, after 3 months of exercise, BMI, HR, SBP, DBP, PP, TG, TC, LDL-C, and Glu all significantly decreased (p < 0.05). (2) Moreover, the quality of life of subjects in the research group obviously improved after 3 months of t'ai chi exercise (p < 0.05). CONCLUSIONS: t'ai chi exercise can reduce the level of blood pressure in young and middle-aged in-service staff with grade 1 hypertension, control weight, slow down the HR, improve metabolism, and improve quality of life. t'ai chi is an exercise suitable for in-service hypertension subjects.

RESUMO

Background Very little research has been done to simultaneously investigate the effects of Tai Chi (TC) on depression and heart rate variability (HRV). This study, therefore, attempted to explore the effects of TC on depression and on HRV parameters. Methods Sixty older individuals with depression score of 10 or above (the Geriatric Depression Scale, GDS) were randomly assigned into two groups: TC (n = 30) and control group (n = 30). Participants in the experimental group participated in a 24-week TC training program (three 60-min sessions per week), whereas individuals in the control group maintained their unaltered lifestyle. Depression and HRV were measured using the GDS and digital electrocardiogram at baseline and after the 24-week intervention. Results The TC had produced significant positive chances in depression and some HRV parameters (mean heart rate, RMSSD, HF, LFnorm, and HFnorm) (p < 0.05), whereas these positive results were not observed in the control group. Conclusions The results of this study indicated that TC may alleviate depression of the elderly through modulating autonomous nervous system or HRV parameters. This study adds to a growing body of research showing that TC may be effective in treating depression of the elderly. Tai Chi as a mild to moderate mind-body exercise is suitable for older individuals who suffer from depression.

RESUMO

"Xishuang" is a special phenomenon that chemical composition of medicinal materials crystallize on the surface exposed to air for a long time. We summarized Herbal textual research of "Xishuang" phenomenon of six herbs, such as Schisandrae Chinensis Fructus, Moutan Cortex, Atractylodis Rhizoma, Magnoliae Officinalis Cortex, dried persimmon frost and watermelon frost. From historical perspective, cream of Schisandrae Chinensis Fructus was firstly discovered in Lei Gong's Moxibustion Theory. Thereafter, dried persimmon frost was found in Song Dynasty, which was named "white persimmon" in Ben Cao Tu Jing and had become an independent medicine in Compendium of Materia Medica. Then, watermelon frost was found in Yang Yi Da Quan of the Qing Dynasty, and Moutan Cortex's "sand star" was recorded in Zeng Ding Wei Yao Tiao Bian of the Republic of China. After that, "Xishuang" phenomenon of Atractylodis Rhizomaand Magnoliae Officinalis Cortex were reported in 1950s and 1960s in succession. The pattern of "Xishuang" is divided into different type, natural "Xishuang" includes Schisandrae Chinensis Fructus, Moutan Cortex, Atractylodis Rhizoma and Magnoliae Officinalis Cortex, artificial "Xishuang" includes watermelon frost, and dried persimmon frost formed crystals by using artificial intervention. The above 6 kinds of herbs have different crystal structure and chemical composition. Therefore, according to traditional identification experience, "Xishuang" phenomenon is related to varieties and quality of medicinal herbs. These research provide herbalism basis for the modern study of "Xishuang" medicinal materials.

RESUMO

Suo Quan pill(SQP), a well-known and classical traditional Chinese medicine compound, consists of three traditional Chinese medicine: Alpinia oxyphylla Miq., Lindera aggregata (Sims) Kosterm., Dioscorea opposite. Its effect was summarized as supplementing kidney-yang and shrinkaging urination. This study evaluated the effects of the serum of rats treated with Suo Quan pill on embryonic stem cells(ES cells). Cell proliferation was detected by MTT assay. Cell cycle and apoptosis of ES cells were evaluated with flow cytometry. Nanog mRNA expression was verified by fluorescence quantitative PCR and Nanog protein in ES cells was determined by Western blot. The serum of SQP-treated rats not only promoted ES cells proliferation and Nanog expression in ES cells, but also inhibited H202 stimulated cell apoptosis. Furthermore, the serum of rats containing SQP affected the cell cycle distribution of ES cells, reducing the percentage of cells in G0/G1phase and increasing the percentage of cells in G2/M phase, increasing the proliferation index of ES cells. These results illustrate that the enhanced effect of SQP on ES cells proliferation is in part due to the increased expression of Nanog in ES cells, the accelerated cell cycle period and the inhibited apoptosis of ES cells.

RESUMO

OBJECTIVE: To systematically review literature about the rehabilitative effects of traditional Chinese exercises (TCEs) on limb function among patients with stroke. METHODS: Systematic review and meta-analysis of randomized controlled trials (RCTs). Twelve electronic databases were searched from their inceptions to February 2017, including PudMed, The Cochrane Library, Web of Science, EMBase, Science Direct, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine, Chinese Scientific Journal Database, China National Knowledge Infrastructure, Chinese Biomedical Literature Database and WanFang Data. RCTs were located to examine the rehabilitative effects of TCEs on limb function among stroke patients. Two authors independently screened the literature, extracted data and assessed the risk bias of the included studies. Methodological quality evaluation and meta-analysis of included studies was performed by using Cochrane Collaboration's tool (RevMan 5.3). RESULTS: A total of 31 RCTs with 2349 participants were included. Results of meta-analysis showed that TCEs produced positive effects on limb motor function (random effects model, standardized mean difference [SMD] = 1.21, 95% confidence interval [CI] = 0.66 to 1.77, P < 0.01), balance function{Berg balance scale: (random effects model, SMD = 2.07, 95%CI = 1.52 to 2.62, P < 0.01), timed-up-and-go test: (fixed effects model, mean difference [MD] = -1.77, 95%CI = -2.87 to -0.67, P < 0.01)}, activities of daily living (ADL) ability {Barthel Index scale: (random effects model, MD = 15.60, 95%CI = 7.57 to 23.63, P < 0.01), Modified Barthel Index scale: (random effects model, MD = 12.30, 95%CI = 7.48 to 17.12, P < 0.01)}, and neurological impairment (fixed effects model, MD = -2.57, 95%CI = -3.14 to -2.00, P < 0.01). After subgroup analysis and sensitivity analysis, the positive effects did not be affected by different types of TCEs and different lengths of intervention time. However, TCEs were no benefit to physical function on Short Physical Performance Battery and 2-min Step Test among stroke patients. CONCLUSION: Current evidence showed that TCEs produced positive effects on limb motor function, balance function, ADL ability and neurological impairment among stroke patients. More large-scale, high-quality, multiple center RCTs are required to further verify above conclusions in the future.

RESUMO

BACKGROUND: Improvement of the quality of life in perimenopausal women has recently become an important global health issue. Extensive research reports provide evidence of Tai Chi for the quality of life, but no systematic review has individually investigated Tai Chi as a main intervention on the quality of life in perimenopausal women. OBJECTIVE: To assess clinical evidence of Tai Chi for the quality of life in perimenopausal women. METHODS: Studies related to the effect of Tai Chi on the quality of life in perimenopausal women in the databases of China and abroad were searched. RevMan version 5.2 software was used, and the Medical Outcomes Study 36-item short form health survey (SF-36) and bone mineral density (BMD) were selected as evaluation indices. RESULTS: Five trials were included. The results of this study showed that Tai Chi had a significant effect on bodily pain, general health, vitality, mental health of SF-36, and the spine dimension of BMD, as supported by the following data: bodily pain (Standard Mean Difference [SMD] = -3.63; 95% confidence interval [CI] [-6.62, -0.64]; p = .02); general health (SMD = -5.08; 95% CI [-7.60, -2.56]; p < .0001); vitality (SMD = -5.67; 95% CI [-8.54, -2.81], p = .0001); mental health (SMD = -2.51; 95% CI [-4.82, -0.20], p = .03); and spine dimension of BMD (SMD = -0.06; 95% CI [-0.10, -0.01]; p = .01). However, Tai Chi had no effect on physical function, emotional health, social function, role-physical of SF-36, and the hip dimension of BMD, as supported by the following data: physical function (SMD = -1.79; 95% CI [-5.15, 1.57]; p = .30); emotional health (SMD = -2.90; 95% CI [-7.23, 1.43], p = .19]; social function (SMD = -2.23, 95% CI [-5.08, 0.61], p = .12; role-physical (SMD = - 1.18; 95% CI [-4.84, 2.47], p = .53; and hip dimension of BMD (SMD = -0.01; 95% CI [-0.03, 0.01]; p = .31). LINKING EVIDENCE TO ACTION: This systematic review found significant evidence for Tai Chi improving bodily pain, general health, vitality, mental health of SF-36, and the spine dimension of BMD in patients with perimenopausal syndrome. Findings suggest that Tai Chi might be recommended as effective and safe adjuvant treatment for patients with perimenopausal syndrome. More high-quality randomized controlled trials are urgently needed to confirm these results.

RESUMO

This study examined the effects of regular Tai Chi practice and jogging on the neuromuscular activity of the trunk, hip, and ankle joint muscles of older people during lateral postural perturbation. A total of 42 older people participated in the study and formed the Tai Chi, jogging, and sedentary control groups. Electromyography signals were collected from the peroneus longus, anterior tibialis, gluteus medius, and erector spinae during unpredictable mediolateral perturbation. The Tai Chi group exhibited significantly faster latencies of the tibialis anterior and erector spinae than the control group. The jogging group showed a significantly shorter neuromuscular reaction time of the erector spinae than the control group. No significant difference was observed between the Tai Chi and jogging groups. Long-term regular Tai Chi practice enhanced the neuromuscular reaction of the erector spinae and tibialis anterior to lateral perturbation and will help timely posture correction when lateral postural distributions occur.

RESUMO

Several studies reported that Tai Chi showed potential effects for chronic pain, but its role remains controversial. This review assessed the evidence regarding the effects of Tai Chi for chronic pain conditions. 18 randomized controlled trials were included in our review. The aggregated results have indicated that Tai Chi showed positive evidence on immediate relief of chronic pain from osteoarthritis (standardized mean difference [SMD], -0.54; 95% confidence intervals [CI], -0.77 to -0.30; P < 0.05). The valid duration of Tai Chi practice for osteoarthritis may be more than 5 weeks. And there were some beneficial evidences regarding the effects of Tai Chi on immediate relief of chronic pain from low back pain (SMD, -0.81; 95% CI, -1.11 to -0.52; P < 0.05) and osteoporosis (SMD, -0.83; 95% CI, -1.37 to -0.28; P = 0.003). Therefore, clinicians may consider Tai Chi as a viable complementary and alternative medicine for chronic pain conditions.

RESUMO

This paper describes the preliminary measurement of the Newtonian gravitational constant G with the angular acceleration feedback method at HUST. The apparatus has been built, and preliminary measurement performed, to test all aspects of the experimental design, particularly the feedback function, which was recently discussed in detail by Quan et al. The experimental results show that the residual twist angle of the torsion pendulum at the signal frequency introduces 0.4 ppm to the value of G. The relative uncertainty of the angular acceleration of the turntable is approximately 100 ppm, which is mainly limited by the stability of the apparatus. Therefore, the experiment has been modified with three features: (i) the height of the apparatus is reduced almost by half, (ii) the aluminium shelves were replaced with shelves made from ultra-low expansion material and (iii) a perfect compensation of the laboratory-fixed gravitational background will be carried out. With these improvements, the angular acceleration is expected to be determined with an uncertainty of better than 10 ppm, and a reliable value of G with 20 ppm or below will be obtained in the near future.

RESUMO

Growing evidence indicates that chronic neuropathic pain is frequently accompanied by an array of psychiatric diseases, such as depression and anxiety. Electroacupuncture (EA), as one therapy of traditional Chinese medicine, has displayed potent antidepressant-like effects in numerous clinical studies. The present study was designed to examine the possible effects of EA on the depressive and anxiety disorders induced by neuropathic pain. A classic rat model of neuropathic pain was produced by chronic constriction injury (CCI) of the sciatic nerve. EA was performed on acupoints "Bai-Hui" (GV20) and unilateral "Yang-Ling-Quan" (GB34). The antidepressive and anxiolytic effects of EA treatment were analyzed using the forced swimming test (FST) and the elevated plus maze (EPM) test, respectively. CCI resulted in remarkable depression- and anxiety-like behaviors, whereas the chronic EA treatment significantly improved the behavioral deficits of CCI rats. Moreover, the phosphorylation level of the NMDA receptor type 1 (NR1) subunit was decreased in the hippocampus of CCI rats. Intriguingly, continuous EA treatment effectively blocked this decrease in the levels of pNR1. These results suggested that EA has antidepressive and anxiolytic effects on rats with neuropathic pain and that this might be associated with restoring the phosphorylation of NR1 in the hippocampus.
