Curcumin regulates autophagy through SIRT3-SOD2-ROS signaling pathway to improve quadriceps femoris muscle atrophy in KOA rat model.

Knee osteoarthritis (KOA) usually leads to quadriceps femoris atrophy, which in turn can further aggravate the progression of KOA. Curcumin (CUR) has anti-inflammatory and antioxidant effects and has been shown to be a protective agent for skeletal muscle. CUR has been shown to have a protective effect on skeletal muscle. However, there are no studies related to whether CUR improves KOA-induced quadriceps femoris muscle atrophy. We established a model of KOA in rats. Rats in the experimental group were fed CUR for 5 weeks. Changes in autophagy levels, reactive oxygen species (ROS) levels, and changes in the expression of the Sirutin3 (SIRT3)-superoxide dismutase 2 (SOD2) pathway were detected in the quadriceps femoris muscle of rats. KOA led to quadriceps femoris muscle atrophy, in which autophagy was induced and ROS levels were increased. CUR increased SIRT3 expression, decreased SOD2 acetylation and ROS levels, inhibited the over-activation of autophagy, thereby alleviating quadriceps femoris muscle atrophy and improving KOA. CUR has a protective effect against quadriceps femoris muscle atrophy, and KOA is alleviated after improvement of quadriceps femoris muscle atrophy, with the possible mechanism being the reduction of ROS-induced autophagy via the SIRT3-SOD2 pathway.

Effects of foot reflexology massage on pregnant women: a systematic review and meta-analysis of randomized controlled studies.

To explore the effects of foot reflexology massage on anxiety, pain, duration of labor, labor satisfaction, blood pressure, pulse rate and respiratory rate in pregnant women. We systematically searched eight databases for randomized controlled studies on the effects of foot reflexology massage on pregnant women. The inclusion criteria were as follow: participants were pregnant woman; the intervention is foot reflexology or foot massage; the control intervention is placebo, usual care, or no intervention; outcome indicators included pain, anxiety, birth satisfaction, duration of labor, blood pressure, pulse, and respiration; and study type was randomized controlled study. Studies that did not meet the above requirements were excluded. We assessed the quality of the included studies using the Physiotherapy Evidence Database scale, the risk of bias using the Risk of Bias 2.0 tool, and the level of evidence for the outcomes using the Grading of Recommendations Assessment Development and Evaluation. We used Review Manager 5.3 for data analysis and generated funnel plots to assess publication bias. In addition, sensitivity analysis was used to test the stability of the results. A total of 13 randomized controlled studies with 1189 participants were included in this study. Compared to the control group, foot reflexology massage reduced anxiety and pain in pregnant women, shortened the three stages of labor, and increased birth satisfaction. In addition, it also reduced the pulse rate and respiratory rate of pregnant women, but not for blood pressure. Foot reflexology massage can significantly reduce anxiety and pain, shorten the duration of labor, increase birth satisfaction, and stabilize vital signs in pregnant women. It is a safe and non-invasive form of complementary therapy.PROSPERO registered number: CRD42022359641. URL: https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=359641 .

Effects of rapeseed oil on body composition and glucolipid metabolism in people with obesity and overweight: a systematic review and meta-analysis.

To investigate the effects of rapeseed oil on body composition, blood glucose and lipid metabolism in people with overweight and obesity compared to other cooking oils. We searched eight databases for randomized controlled studies (including randomized crossover trials). The risk of bias for the included studies was assessed using the Cochrane Risk of Bias 2.0 tool. The Grading of Recommendations Assessment Development and Evaluation (GRADE) criteria were used to evaluate the quality of the outcomes. The methodological quality of the included studies was assessed using the Physiotherapy Evidence Database (PEDro) scale. Sensitivity analysis was used to check the stability of the pooled results. Statistical analysis was carried out using Review Manager 5.3 software. As a result, fifteen randomized controlled studies (including six parallel studies and nine crossover studies) were included in this study. Compared to other edible oils, rapeseed oil significantly reduced low density lipoprotein cholesterol (LDL-C) (MD = -0.14 mmol/L, 95% CI: -0.21, -0.08, I2 = 0%, P < 0.0001), apolipoprotein B (ApoB) (MD = -0.03 g/L, 95% CI: -0.05, -0.01, I2 = 0%, P = 0.0003), ApoB/ApoA1 (MD = -0.02, 95% CI: -0.04, -0.00, I2 = 0%, P = 0.02) and insulin (MD = -12.45 pmol/L, 95% CI: -19.61, -5.29, I2 = 37%, P = 0.0007) levels, and increased fasting glucose (MD = 0.16 mmol/L, 95% CI: 0.05, 0.27, I2 = 27%, P = 0.003) levels. However, the differences in body weight and body composition between rapeseed oil and control oils were not significant. In a word, rapeseed oil is effective in reducing LDL-C, ApoB and ApoB/ApoA1 levels in people with overweight and obesity, which is helpful in preventing and reducing the risk of atherosclerosis.

Objective: This study aimed to investigate the use intention and influencing factors of telerehabilitation in people with rehabilitation needs. Methods: This cross-sectional survey recruited a total of 183 participants with rehabilitation needs from May 2022 to December 2022. Sociodemographic and medical data were collected by a structured questionnaire. The factors influencing the use intention of telerehabilitation were measured by the extended Unified Theory of Acceptance and Use of Technology (UTAUT) model. Multiple hierarchical regression analyses were performed. Results: A total of 150 valid questionnaires were included for analysis. The results indicated that the use intention of telerehabilitation was overall high in people with rehabilitation needs. Health condition (ß = -0.21, p = 0.03), performance expectancy (ß = 0.21, p = 0.01), facilitating conditions (ß = 0.25, p = 0.03), perceived trust (ß = 0.25, p < 0.01), and self-efficacy (ß = 0.19, p = 0.04) were significant factors influencing the use intention of telerehabilitation. Conclusion: Overall, the use intention of telerehabilitation is high in individuals with rehabilitation needs. Health conditions, performance expectancy, facilitating conditions, perceived trust, and self-efficacy are important factors influencing the use intention of telerehabilitation in individuals with rehabilitation needs.

Effects of Web-Based Mindfulness-Based Interventions on Anxiety, Depression, and Stress Among Frontline Health Care Workers During the COVID-19 Pandemic: Systematic Review and Meta-Analysis.

BACKGROUND: Since 2019, the COVID-19 outbreak has spread around the world, and health care workers, as frontline workers, have faced tremendous psychological stress. OBJECTIVE: The purpose of this study is to explore whether web-based mindfulness-based interventions continue to have a positive impact on anxiety, depression, and stress among health care workers during the COVID-19 pandemic. METHODS: The inclusion criteria were as follows: (1) participants were frontline health care workers during the COVID-19 pandemic; (2) the experimental group was a web-based mindfulness-based intervention; (3) the control group used either general psychological intervention or no intervention; (4) outcome indicators included scales to assess anxiety, depression, and stress; and (5) the study type was a randomized controlled study. Studies that did not meet the above requirements were excluded. We searched 9 databases, including Web of Science, Embase, PubMed, Cochrane Library, Scopus, ScienceDirect, SinoMed, China National Knowledge Infrastructure (CNKI), and Wanfang Database, for randomized controlled studies on the effects of web-based mindfulness-based interventions on common mental disorder symptoms among health care workers from January 1, 2020, to October 20, 2022. The methodological quality of the included studies was assessed using the Physiotherapy Evidence Database scale. The Cochrane risk of bias tool was used to assess the risk of bias. Subgroup analysis was used to look for sources of heterogeneity and to explore whether the results were the same for subgroups under different conditions. Sensitivity analysis was used to verify the stability of the pooled results. RESULTS: A total of 10 randomized controlled studies with 1311 participants were included. The results showed that web-based mindfulness-based interventions were effective in reducing the symptoms of anxiety (standard mean difference [SMD]=-0.63, 95% CI -0.96 to -0.31, P<.001, I2=87%), depression (SMD=-0.52, 95% CI -0.77 to -0.26, P<.001, I2=75%), and stress (SMD=-0.20, 95% CI -0.35 to -0.05, P=.01, I2=58%) among health care workers during the COVID-19 pandemic, but with wide CIs and high heterogeneity. CONCLUSIONS: Web-based mindfulness-based interventions may be effective in reducing the symptoms of anxiety, depression, and stress among frontline health care workers during the COVID-19 pandemic. However, this effect is relatively mild and needs to be further explored by better studies in the future.

Efficacy and safety of noninvasive brain stimulation for patients with cerebellar ataxia: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: With the development of noninvasive brain stimulation (NIBS) techniques, many researchers have turned their attention to NIBS as a promising treatment for cerebellar ataxia. Therefore, we conducted a systematic review and meta-analysis to investigate the efficacy and safety of NIBS in treating patients with cerebellar ataxia. METHODS: Databases, including PubMed, Embase, Web of Science, Medline, and Cochrane Library, were retrieved for relevant randomized controlled trials (RCTs). Two researchers conducted literature screening, data extraction, literature quality assessment, and heterogeneity analysis between RCTs. According to the magnitude of heterogeneity I2, an appropriate data analysis model was selected for meta-analysis. RESULTS: A total of 14 RCTs including 406 patients with cerebellar ataxia met the inclusion criteria. The included RCTs had an overall low-risk bias and an intermediate level of evidence recommendation for key outcome indicators, such as the scale for the assessment and rating of ataxia (SARA) and international cooperative ataxia rating scale (ICARS). The results of meta-analysis showed that cerebellar NIBS, including transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS), was effective in reducing the SARA scores (MD = - 3.45, 95%CI = [- 4.85, - 2.50], P < 0.05) and ICARS scores (MD = - 10.87, 95%CI = [- 14.46, - 7.28], P < 0.05) in patients with cerebellar ataxia compared to controls. Subgroup analysis showed that the efficacy of tDCS and rTMS was statistically different in patients with cerebellar ataxia as assessed by the SARA scores, but not by the ICARS scores. There was statistically significant difference in the efficacy of NIBS for the treatment of cerebellar ataxia caused by different etiologies. As for safety, 8 of 14 included studies documented the adverse effects of NIBS, and only two studies reported the mild adverse events of NIBS. CONCLUSIONS: Cerebellar NIBS was safe and effective in improving the motor coordination of patients with cerebellar ataxia, and tDCS was better than rTMS in the treatment of cerebellar ataxia. In addition, the efficacy of NIBS was different in the treatment of different types of cerebellar ataxia.

Do dietary supplements prevent loss of muscle mass and strength during muscle disuse? A systematic review and meta-analysis of randomized controlled trials.

Objective: We performed a systematic review and meta-analysis of existing randomized controlled trials (RCTs) to assess whether dietary supplements can prevent loss of muscle mass and strength during muscle disuse. Methods: We searched the following databases: PubMed, Embase, Cochrane, Scopus, Web of Science, and CINAHL for RCTs assessing the effect of dietary supplements on disuse muscular atrophy without language and time restrictions. Muscle strength and leg lean mass were used as the primary outcome indicators. Muscle cross-sectional area (CSA), muscle fiber type distribution, peak aerobic capacity and muscle volume were used as secondary outcome indicators. The risk of bias was assessed using the Cochrane Collaboration's Risk of Bias tool. Heterogeneity was tested using the I2 statistic index. Mean and standard deviation of outcome indicators were extracted from the intervention and control groups to calculate effect sizes and 95% confidence intervals, with the significance level set at P < 0.05. Results: Twenty RCTs were included with a total of 339 subjects. The results showed that dietary supplements had no effect on muscle strength, CSA, muscle fiber type distribution, peak aerobic capacity or muscle volume. But dietary supplements have a protective effect on the lean mass of the legs. Conclusion: Dietary supplements can improve lean leg mass, but did not show a tendency to have an effect on muscle strength, CSA, muscle fiber type distribution, peak aerobic capacity or muscle volume during muscle disuse.

Therapeutic effects of repetitive transcranial magnetic stimulation on cognitive impairment in stroke patients: a systematic review and meta-analysis.

Background: In recent years, repetitive transcranial magnetic stimulation (rTMS) has emerged as a noninvasive and painless treatment for post-stroke cognitive impairment (PSCI). However, few studies have analyzed the intervention parameters of cognitive function and the effectiveness and safety of rTMS for treating patients with PSCI. Thus, this meta-analysis aimed to analyze the interventional parameters of rTMS and evaluate the safety and effectiveness of rTMS for treating patients with PSCI. Methods: According to the PRISMA guidelines, we searched the Web of Science, PubMed, EBSCO, Cochrane Library, PEDro, and Embase to retrieve randomized controlled trials (RCTs) of rTMS for the treatment of patients with PSCI. Studies were screened according to the inclusion and exclusion criteria, and two reviewers independently performed literature screening, data extraction, and quality assessment. RevMan 5.40 software was used for data analysis. Results: 12 RCTs involving 497 patients with PSCI met the inclusion criteria. In our analysis, rTMS had a positive therapeutic effect on cognitive rehabilitation in patients with PSCI (P < 0.05). Both high-frequency rTMS and low-frequency rTMS were effective in improving the cognitive function of patients with PSCI by stimulating the dorsolateral prefrontal cortex (DLPFC), but their efficacy was not statistically different (P > 0.05). Conclusions: rTMS treatment on the DLPFC can improve cognitive function in patients with PSCI. There is no significant difference in the treatment effect of high-frequency rTMS and low-frequency rTMS in patients with PSCI between high-frequency and low-frequency rTMS.

The Efficacy and Safety of Telerehabilitation for Fibromyalgia: Systematic Review and Meta-analysis of Randomized Controlled Trials.

BACKGROUND: Fibromyalgia is a chronic pain syndrome characterized by persistent and widespread musculoskeletal pain. Telerehabilitation is a promising treatment for patients with fibromyalgia through long-term monitoring, intervention, supervision, consultation, and education. OBJECTIVE: This study aimed to perform a comprehensive systematic review and meta-analysis of the efficacy and safety of telerehabilitation in patients with fibromyalgia. METHODS: Randomized controlled trials (RCTs) related to fibromyalgia and telerehabilitation were systematically searched in the PubMed, PEDro, Cochrane Library, ScienceDirect, Ovid MEDLINE, Embase, and Web of Science databases from inception to November 13, 2022. Two independent researchers screened the literatures and evaluated the methodological quality using the Cochrane Risk of Bias Tool. The outcome measures included the Fibromyalgia Impact Questionnaire scale, pain intensity, depression, pain catastrophizing, quality of life (QoL), and adverse events. Pooled effect sizes were calculated by Stata SE 15.1; a fixed effects model was used when I2<50%, whereas a random effects model was used when I2≥50%. RESULTS: A total of 14 RCTs with 1242 participants were included in this meta-analysis. The pooled results indicated that the telerehabilitation improved the Fibromyalgia Impact Questionnaire score (weighted mean difference -8.32, 95% CI -11.72 to -4.91; P<.001), pain intensity (standardized mean difference [SMD] -0.62, 95% CI -0.76 to -0.47; P<.001), depression levels (SMD -0.42, 95% CI -0.62 to -0.22; P<.001), pain catastrophizing (weighted mean difference -5.81, 95% CI -9.40 to -2.23; P=.001), and QoL (SMD 0.32, 95% CI 0.18 to 0.47; P<.001) in patients with fibromyalgia compared to control interventions. Only 1 RCT reported a mild adverse event of telerehabilitation; the other 13 RCTs did not mention this. CONCLUSIONS: Telerehabilitation can improve the symptoms and QoL of fibromyalgia. However, the safety of telerehabilitation remains uncertain due to the lack of sufficient evidence for the management of fibromyalgia. More rigorously designed trials are needed in the future to verify the safety and efficacy of telerehabilitation in fibromyalgia.

Effect of pelvic floor muscle training on urinary incontinence after radical prostatectomy: An umbrella review of meta-analysis and systematic review.

OBJECTIVE: To analyse the specific exercise effects of pelvic floor muscle training (PFMT) with or without biofeedback or electrical stimulation on urinary incontinence rehabilitation after radical prostatectomy. DATA SOURCES: We searched PubMed, Embase, Cochrane Database of Systematic Reviews, Web of Science and Scopus databases for systematic reviews and meta-analyses on PFMT for urinary incontinence after radical prostatectomy from inception to 3 October 2022. REVIEW METHODS: Two authors independently extracted key data from the included studies. The methodological quality of the included studies was assessed using the A Measure Tool to Assess Systematic Reviews-2 checklist. Grading of Recommendations Assessment Development and Evaluation was used to evaluate the quality of the outcomes. RESULTS: A total of 18 studies with 29,925 patients were included, all of which were of critically low methodological quality. Biofeedback therapy seemed to show additional benefits compared to PFMT alone; however, the adjunctive role of electrical stimulation remained more controversial due to the lack of strong evidence. Preoperative PFMT sometimes, but not always, showed the potential to improve urinary incontinence. PFMT with the guidance of a therapist could bring some benefits to the patient and was more acceptable to the patient, but consumed some medical resources. CONCLUSIONS: PFMT has a good effect on improving post-radical prostatectomy incontinence in men, and biofeedback can have an additional beneficial effect on patients, especially in the short-term and medium-term. However, there is insufficient evidence to suggest that electrical stimulation is beneficial for patients with urinary incontinence.

Effects of repetitive peripheral magnetic stimulation on spasticity evaluated with modified Ashworth scale/Ashworth scale in patients with spastic paralysis: A systematic review and meta-analysis.

Background: Spasticity is a common motor disorder resulting from upper motor neuron lesions. It has a serious influence on an individual's motor function and daily activity. Repetitive peripheral magnetic stimulation (rPMS) is a non-invasive and painless approach developed for therapeutic intervention in clinical rehabilitation. However, the effectiveness of this intervention on spasticity in patients with spastic paralysis remains uncertain. Objective: This study aimed to investigate the effectiveness of rPMS on spasticity, motor function, and activities of daily living in individuals with spastic paralysis. Methods: PubMed, PEDro, Embase, Cochrane Library, and Web of Science were searched for eligible papers with date up to March 31, 2022. Two independent researchers conducted study screening, data extraction, and methodological quality assessment. RCTs that explored the effects of rPMS on spasticity, motor function, and activities of daily living in patients with spastic paralysis were included for review. The Cochrane collaboration tool was used to assess methodological quality. The cumulative effects of available data were processed for a meta-analysis using Reedman software. Results: Eight studies with 297 participants were included. Most of the studies presented low to moderate risk of bias. Compared with the control group, the results showed that rPMS had a significant effect on spasticity (all spasticity outcomes: standardized mean difference [SMD] = -0.55, 95% confidence interval [CI]: -0.94 to -0.16, I 2 = 40%, and P = 0.006, Modified Ashworth Scale: mean difference [MD] = -0.48, 95% CI: -0.82 to -0.14, I 2 = 0%, and P = 0.006), motor function (Fugl-Meyer Assessment: MD = 4.17, 95% CI: 0.89 to 7.46, I 2 = 28%, and P = 0.01), and activities of daily living (Barthel Index: MD = 5.12, 95% CI: 2.58 to 7.67, I 2 = 0%, and P < 0.0001). No side effect was reported. Conclusion: The meta-analysis demonstrated that the evidence supported rPMS in improving spasticity especially for passive muscle properties evaluated with Modified Ashworth Scale/Ashworth Scale, as well as motor function and daily activity of living in individuals with spastic paralysis. Study registration: The reviewed protocol of this study is registered in the international prospective register of systematic reviews (PROSPERO) (CRD42022322395).

Effects of WB-EMS and protein supplementation on body composition, physical function, metabolism and inflammatory biomarkers in middle-aged and elderly patients with sarcopenic obesity: A meta-analysis of randomized controlled trials.

BACKGROUND: The patients with sarcopenic obesity (SO) have the characteristics of both sarcopenia and obesity, that is, less muscle mass and increased fat mass, and their morbidity, disability and mortality are higher than patients with sarcopenia or obesity alone. OBJECTIVES: To investigate the effects of whole-body electromyostimulation (WB-EMS) training and protein supplementation intervention on body composition, physical function, metabolism and inflammatory biomarkers in middle-aged and elderly patients with SO. METHODS: We searched for randomized controlled trials in seven databases, including PubMed, Web of Science, Embase, Cochrane Library, Scopus, SinoMed, and CNKI as of July 3, 2021. The methodological quality of each included study was assessed using the Physiotherapy Evidence Database (PEDro) scale. The Cochrane Risk of Bias Tool was used to assess the risk of bias. Statistical analysis was performed using Review Manager 5.3. RESULTS: Eleven randomized controlled studies with a total of 779 participants were included in this meta-analysis. WB-EMS training improved sarcopenia Z-score (MD = -1.52, 95 % CI: -2.27, -0.77, P < 0.0001) and waist circumference (WC) (MD = -1.41, 95 % CI: -2.62, -0.20, P = 0.02), and increased skeletal muscle mass index (SMI) (MD = 1.27, 95 % CI: 0.66,1.88, P < 0.0001) and appendicular skeletal muscle mass (ASMM) (MD = 0.68, 95 % CI: 0.08, 1.27, P = 0.03). Protein supplementation intervention reduced body fat rate (BF%) (MD = -1.28, 95 % CI: -1.88, -0.68, P < 0.0001, I2 = 0 %), total body fat (TBF) (MD = -0.98, 95 % CI: -1.65, -0.31, P = 0.004, I2 = 0 %) and trunk body fat mass (TBFM) (MD = -0.50, 95 % CI: -0.94, -0.06, P = 0.03, I2 = 0 %), and increased grip strength (GS) (MD = 1.13, 95 % CI: 0.06, 2.21, P = 0.04, I2 = 0 %). The combination of WB-EMS and protein supplements is beneficial to most body components and physical functions, such as SMI (MD = 1.21, 95 % CI: 0.73, 1.51, P < 0.00001, I2 = 0 %), GS (MD = 1.60, 95 % CI: 0.80, 2.40, P < 0.0001, I2 = 45 %) and walking speed (WS) (MD = 0.04, 95 % CI: 0.02, 0.06, P < 0.0001, I2 = 49 %). Compared with protein supplementation alone, WB-EMS could have an additional beneficial effect on BF% (MD = -0.92, 95 % CI: -1.80, -0.04, P = 0.04) and WC (MD = -1.03, 95 % CI: -1.70, -0.36, P = 0.003). Nevertheless, the addition of protein supplements did not provide any additional benefit compared with WB-EMS alone. In addition, there was almost no positive effect of WB-EMS and protein supplements on metabolic and inflammatory biomarkers. CONCLUSIONS: As things stand, protein supplementation intervention can effectively reduce body fat percentage, fat mass, and increase grip strength in SO patients. Both WB-EMS and protein supplementation intervention had no significant effects on metabolic and inflammatory biomarkers. WB-EMS combined with protein supplementation intervention was beneficial for SO patients in many ways. Due to the small number of studies, further studies are needed to confirm the efficacy of WB-EMS alone or in combination with protein supplementation intervention in SO patients.

Effects of resistance training on body composition and physical function in elderly patients with osteosarcopenic obesity: a systematic review and meta-analysis.

Osteosarcopenic obesity (OSO) is a complex disease commonly seen in the elderly. We found that resistance training may improve bone mineral density, skeletal muscle mass, and body fat percentage in patients with OSO. Therefore, resistance training is beneficial for elderly OSO patients and is worth being promoted. PURPOSE: Investigate effects of resistance training on body composition and physical function in elderly osteosarcopenic obesity (OSO) patients. METHODS: PubMed, Web of Science, Embase, Cochrane Library, Medline, SinoMed, CNKI, and Wanfang Database were searched from inception until October 13, 2021.Two independent researchers extracted the key information from each eligible study. The methodological quality of included studies was assessed using the Physiotherapy Evidence Database (PEDro) scale. The Cochrane Risk of Bias Tool was used to assess the risk of bias. Grading of Recommendations Assessment Development and Evaluation (GRADE) was used to evaluate the quality of the outcomes. Sensitivity analysis indicated the stability of the results. Statistical analysis was performed using Review Manager 5.3. RESULTS: Four randomized controlled studies meeting the inclusion criteria were included, with 182 participants. Twelve weeks of resistance training improved bone mineral density (BMD, mean difference (MD) = 0.01 g/cm2, 95% confidence interval (CI): 0.001, 0.02, P = 0.03, I2 = 0%), skeletal muscle mass (SMM, MD = 1.19 kg, 95% CI: 0.50, 1.89, P = 0.0007, I2 = 0%), Z score, timed chair rise test (TCR), and body fat percentage (BFP, MD = - 1.61%, 95% CI: - 2.94, - 0.28, P = 0.02, I2 = 50%) but did not significantly affect skeletal muscle mass index (SMI, MD = 0.20 kg/m2, 95% CI: - 0.25, 0.64, P = 0.38, I2 = 0%) or gait speed (GS). CONCLUSIONS: Resistance training is a safe and effective intervention that can improve many parameters, including BFP, SMM, and Z score, among OSO patients and is a good option for elderly individuals to improve their physical fitness.

Flavonoid-enriched extract from Millettia speciosa Champ prevents obesity by regulating thermogenesis and lipid metabolism in high-fat diet-induced obese C57BL/6 mice.

Millettia speciosa (M. speciosa) Champ is a medicinal and edible plant. The roots are rich in flavonoids, which possess multiple biological activities, including lipid-lowering effects. This study aimed to explore the effect of flavonoid-enriched extract from M. speciosa (FMS) on obesity. The UPLC-Q-TOF-MS analysis and chromatographic analysis were adopted to identify flavonoid compounds in FMS. Male C57BL/6J mice were fed with a high-fat diet for 3 months and were then treated with FMS (50 or 100 mg/kg/d) or Orlistat (10 mg kg-1 d-1) for another 8 weeks. A total of 35 flavonoids were identified in the extract of M. speciosa root. FMS reduced body weight gain, liver weight gain, white adipose tissue, lipid accumulation, and blood glucose. The levels of TG, ALT, AST, and inflammatory-related adipokines (TNF-α and IL-6) in serum were also reduced by FMS. In addition, FMS promoted thermogenesis in brown adipose tissue and induced the activation of lipolysis, fatty acid oxidation, and oxidative phosphorylation in white adipose tissues. In summary, long-term administration of FMS could ameliorate high-fat diet-induced obesity by stimulating adipose thermogenesis and lipid metabolism.

Traditional Chinese Mind and Body Exercises for Neck Pain: A Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: Neck pain is common and can have a significant impact on patients' physical functionality, mobility, and quality of life (QOL). In clinical practice, traditional Chinese mind and body exercise (TCMBE) is a combination of different types of exercise based on traditional Chinese medicine, including qigong, tai chi, the 12-words-for-life-nurturing exercise, and so on, and many studies have found that it is safe and effective at helping patients with neck pain. OBJECTIVE: The aim of this study was to investigate the effectiveness of TCMBE on pain intensity, functional mobility, and QOL in individuals with neck pain. METHODS: The PubMed, MEDLINE, PEDro, and Embase databases were systematically searched for relevant studies. Randomized controlled trials reporting the effects of TCMBE on pain intensity, functional mobility, and QOL in individuals with neck pain were included. Screening, data extraction, and literature quality assessments were performed independently by two reviewers. RevMan5.4 software was used for data analysis. RESULTS: Six studies with 716 participants met the inclusion criteria. Compared with the control groups, TCMBE had no therapeutic advantage in improving pain intensity (visual analogue scale: mean difference (MD) = 1.8, 95% confidence interval (CI): -7.70 to 11.46, and P = 0.70); functional mobility (neck disability index: MD = 0.15, 95% CI: -6.37 to 6.66, and P = 0.96; neck pain and disability scale: MD = 1.31, 95% CI: -4.10 to 6.71, and P = 0.64); or 36-item short-form health survey (SF-36) scores for physical function (MD = 5.58, 95% CI: -8.03 to 19.18, and P = 0.42), general health (MD = 1.87, 95% CI: -4.99 to 8.72, and P = 0.59), body pain (MD = 2.26, 95% CI: -3.80 to 8.32, and P = 0.46), vitality (MD = 6.24, 95% CI: -1.49 to 13.98, and P = 0.11), social function (MD = 8.06, 95% CI: -4.85 to 20.98, and P = 0.22), role physical (MD = -1.46, 95% CI: -8.54 to 5.62, and P = 0.69), or role emotional (MD = 6.5, 95% CI: -3.45 to 16.45, and P = 0.2). However, TCMBE was less effective at improving mental health results based on the SF-36 survey (MD = 3.37, 95% CI: 0.5 to 6.24, and P = 0.02). CONCLUSIONS: Based on the meta-analysis, there is insufficient evidence to support the clinical use of TCMBE in improving pain intensity and enhancing functional mobility and QOL in individuals with neck pain.

[Analysis of constituents from different parts of Callicarpa nudiflora by UPLC-Q-TOF-MS/MS].

The aim of this study was to clarify the main components of the green leaves of Callicarpa nudiflora,and to compare the difference of main components between the green leaves,yellow leaves,branches and seeds. In this study,ultra-high performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS) coupled with the UNIFI scientific information system was adopted. And the identification of the main chemical components of C. nudiflora was combined with reference materials,literatures and online database. In addition,the difference of main components was analyzed by Progenesis QI,principal component analysis(PCA) and orthogonal partial least squares discriminant(OPLS-DA). A total of 57 compounds were identified in green leaves,including phenylpropanoids,flavonoids and iridoids. Among them,the relative content of phenylethanoid glycosides was highest. Furthermore,the PCA analysis showed that there are significant differences in main components of the branches and other parts of C. nudiflora. Combined with OPLS-DA analysis,nudifloside,parvifloroside B and ß-hydroxysamioside were selected as the characteristic components for distinguish the leaves and branches of C. nudiflora. Our study provided a scientific basis for the collection and identification of C. nudiflora.
