Effect of Bushen Tiansui Decoction on Delayed Fracture Healing: A Systematic Review and Meta-analysis.

This review aimed to validate the therapeutic potential of Bushen Tiansui decoction (BSTSD), a traditional Chinese formulation, in treating delayed union of fractures. Comprehensive database searches identified randomized controlled trials up to September 13, 2022, assessing BSTSD's efficacy in delayed fracture healing. Outcomes were bone metabolism indexes and Harris hip scores. Quality and risk assessments were conducted using the Cochrane Collaboration's tools. Data were analyzed using RevMan software, with sensitivity analysis through Stata. BSTSD significantly improved bone GLA protein (SMD=1.76, P<0.00001) and alkaline phosphatase (SMD=1.31, P<0.00001). Additionally, Harris hip scores for pain, function, deformity, and motion showed marked improvement. BSTSD treatment also demonstrated enhanced clinical efficiency (RR=1.27, P<0.00001) with fewer complications. Sensitivity analyses indicated consistent results. BSTSD shows promise in treating delayed fracture unions, yet conclusions necessitate further high-quality research for validation.

[Effects of catgut embedding and PGLA embedding at "Zusanli" (ST 36) on skin mast cells, substance P and histamine in healthy rats].

OBJECTIVE: To observe the effects of catgut embedding and polyglycolic acid/poly-lactic acid (PGLA) embedding at "Zusanli" (ST 36) on the activation of local skin mast cells (MC), and expression of substance P (SP) and histamine (HA), and to explore the mechanism of the temporal stimulation effect of acupoint catgut embedding and provide a foundation for further research on the initiation mechanism of acupoint catgut embedding. METHODS: One hundred and sixty male SPF-grade SD rats were randomly divided into a blank group (10 rats), a sham-embedding group (50 rats), a catgut group (50 rats), and a PGLA group (50 rats). Each intervention group was further randomly divided into five subgroups according to the time points after intervention: 8 hours, 3 days, 7 days, 14 days, and 21 days, with 10 rats in each subgroup. One-time sham-embedding, catgut embedding and PGLA embedding was given at left "Zusanli" (ST 36) in each intervention group, respectively. The skin and subcutaneous connective tissue of the left "Zusanli" (ST 36) were collected at the corresponding time points after intervention, except for the blank group (only one day before intervention). Toluidine blue staining was used to detect MC count and degranulation, and immunohistochemical staining was used to detect the expression of SP and HA positive cells. RESULTS: There was no significant difference in MC count between the subgroups of each intervention group and the blank group (P>0.05). There was no significant difference in MC count between the subgroups of the catgut group and the PGLA group (P>0.05). The MC count in the 8-hour subgroup of PGLA group was higher than that in the 8-hour subgroup of catgut group (P<0.05), while the MC count in the 21-day subgroup of PGLA group was lower than that in the 21-day subgroup of catgut group (P<0.05). Compared with the blank group, the degranulation rates of MC were increased in the 8-hour and 3-day subgroups of sham-embedding group, 8-hour, 3-day, and 7-day subgroups of catgut group, and 8-hour, 3-day, 7-day, and 14-day subgroups of PGLA group (P<0.01, P<0.05, P<0.001). There was no significant difference in the degranulation rate of MC between the subgroups of the catgut group and the PGLA group (P>0.05), and no significant difference in the degranulation rate of MC between the two embedding groups at the same time point (P>0.05). Compared with the blank group, the expression of SP positive cells was increased in the 8-hour subgroup of sham-embedding group, 8-hour, 3-day, 7-day, and 14-day subgroups of catgut group, and 3-day, 7-day, and 14-day subgroups of PGLA group (P<0.001, P<0.05). The expression of SP positive cells in the 7-day subgroup of catgut group was higher than that in the 8-hour subgroup of catgut group (P<0.05), while the expression of SP positive cells in the 14-day subgroup of catgut group was lower than that in the 7-day subgroup of catgut group (P<0.001). The expression of SP positive cells in the 7-day subgroup of PGLA group was higher than that in the 3-day subgroup of PGLA group (P<0.05), while the expression of SP positive cells in the 14-day subgroup of PGLA group was lower than that in the 7-day subgroup of PGLA group (P<0.01). There was no significant difference in the expression of SP positive cells between the subgroups of the two embedding groups at the same time point (P>0.05). Compared with the blank group, the expression of HA positive cells was increased in the 8-hour, 3-day subgroups of sham-embedding group, 8-hour, 3-day, 7-day, and 14-day subgroups of catgut group, and 8-hour, 3-day, 7-day, 14-day, and 21-day subgroups of PGLA group (P<0.001, P<0.01, P<0.05). The expression of HA positive cells in the 14-day subgroup of catgut group was lower than that in the 7-day subgroup of catgut group (P<0.05), while the expression of HA positive cells in the 3-day subgroup of PGLA group was higher than that in the 8-hour subgroup of PGLA group (P<0.05), and the expression of HA positive cells in the 14-day subgroup of PGLA group was lower than that in the 7-day subgroup of PGLA group (P<0.05). The expression of HA positive cells in the 3-day subgroup of PGLA group was higher than that in the 3-day subgroup of catgut group (P<0.05). CONCLUSION: Catgut and PGLA embedding at "Zusanli" (ST 36) in healthy rats could induce changes in local skin MC, SP, and HA, which may be one of the mechanisms of the temporal stimulation effect after acupoint embedding. There are certain differences between different suture materials. A moderate inflammatory response in the acupoint area, mediated by MC and involving SP and HA, may be one of the initiating factors for the effect of acupoint catgut embedding.

[Effect of catgut implantation on macrophage CD68, tumor necrosis factor-α and interleukin-1ß in "Zusanli" (ST 36) region of rats].

OBJECTIVE: To observe the expression of local macrophages and related cytokines tumor necrosis factor-α (TNF-α) and interleukin-1ß (IL-1ß) after catgut implantation in "Zusanli"(ST 36) in rats, so as to explore its underlying mechanisms in inducing therapeutic effect. METHODS: A total of 110 male SD rats were randomly divided into blank control group (n=10), catgut embedding (CE) group (n=50), and sham CE group (n=50). The CE and sham CE groups were randomly divided into 8 h, 3 d, 7 d, 14 d and 21 d subgroups after the intervention (n=10 in each time point group). Rats of the CE group were uniformly subjected into catgut embedding at ST36 once, and those of the sham CE group received embedding needle puncture at ST36 without catgut retention, and the blank control group was only grasped and fixed without other treatments. Tissues from the ST36 area in each group were collected at the corresponding time points, and the expression of CD68 in macrophages in the acupoint area was detected by immunofluorescence, the contents of TNF-α and IL-1ß in the acupoint area were detected by ELISA. RESULTS: Following catgut embedment at ST36, the contents of TNF-α and IL-1ß, and macrophage CD68 expression level began to increase at 8 h, peaked at 3 d, and then gradually decreased at 7, 14, and 21 d, being still higher in the CE group than in the blank control group at 21 d (P<0.05). Compared with the blank control group, the contents of TNF-α and IL-1ß, and macrophage CD68 expression were significantly increased at 8 h, and 3, 7, 14 and 21 d in the CE group (P<0.05). Following sham CE at ST36, the content of TNF-α at 8 h and 3 d, IL-1ß at 8 h and 3, 7 and 14 d, and expression of CD68 at 8 h were significantly increased in comparison with the blank control group (P<0.05). Comparison between the CE and sham CE groups showed that the contents of IL-1ß at 3, 7, 14 and 21 d, and contents of TNF-α，CD68 expression at 8 h, and 3, 7, 14 and 21 d were significantly higher in the CE group than in the sham CE group (P<0.05). CONCLUSION: Catgut embedding at ST36 can induce an increase levels of inflammatory cytokines TNF-α, IL-1ß and macrophage CD68 in the local microenvironment in rats, which may contribute to its functions in initiating therapeutic effect.

Mediating effect of mindfulness level on the relationship between marital quality and postpartum depression among primiparas.

BACKGROUND: Postpartum depression refers to a depressive episode or depressive symptoms up to 12 mo after delivery. Trait mindfulness has presented a protective factor for postpartum depressive symptoms and proved efficient in improving relationship satisfaction among couples. AIM: To investigate the correlations among mindfulness, marital quality, anxiety, and depression in a large city in western China during the post-corona virus infectious disease-2019 era and determine whether trait mindfulness mediates the relationship between marital quality and postpartum anxiety and depression among primiparas. METHODS: A cross-sectional study was conducted. The self-administered questionnaire was submitted online through smartphones. The levels of mindfulness, anxiety, depression, and marital quality were respectively investigated by the mindful attention awareness scale (MAAS), the self-rating anxiety scale (SAS), the self-rating depression scale (SDS), and the marriage perception scale (MPS) in these enrolled Han and Tujia primiparas. RESULTS: No statistical significance was observed in the prevalence of postpartum anxiety and depression, nor scores of MAAS and MPS-Total in different regions or ethnicities (P > 0.05). However, MPS-Marital interaction (P < 0.05), MPS-Family relationship (MPS-FR) (P < 0.01), and MPS-Marital conflict (MPS-MC) (P < 0.01) scores of urban primiparas were higher than those of rural primiparas. The MPS-MC score of Han primiparas was higher than that of Tujia primiparas (P < 0.05). Negative correlations were observed between MAAS and SAS (r = -0.457, P < 0.01), and MAAS and SDS (r = -0.439, P < 0.01). SAS has revealed a highly positive correlation with SDS (r = 0.720, P < 0.01) and a weak negative correlation with MPS (r = -0.200, P < 0.05). Besides, a weak negative correlation was observed between MAAS and MPS-MC (r = -0.184, P < 0.05), and a weak positive correlation was noticed between SAS and MPS-MC (r = -0.225, P < 0.01). Mediation analysis demonstrated a full mediation effect of mindfulness level on the relationship between MPS-FR and postpartum anxiety (P < 0.05, 95%CI: -0.384 to 0.033), MPS-MC and postpartum anxiety (P < 0.01, 95%CI: 0.027-0.193), MPS-FR and postpartum depression (P < 0.05, 95%CI: -0.365 to 0.031), and MPS-MC and postpartum depression (P < 0.01, 95%CI: 0.022-0.206). CONCLUSION: Mindfulness demonstrates negative correlations with marital conflict, postpartum anxiety and depression, and it may have cross-ethnic and trans-regional characteristics. Although the mindfulness levels have revealed no significant mediating effect between the total score of marital quality and postpartum depression in this study, it demonstrates a full mediation effect on the relationships between family relationships, marital conflict, and postpartum anxiety and depression.

Delving into the role of mindfulness on the relationship among creativity, anxiety, and boredom of young EFL learners.

Anxiety may contribute to agitation and distress in learners that can influence learning. Along with anxiety, boredom has been the focus of many recent investigations in the context of second language (L2) learning involving young learners. Anxiety and boredom would limit learners' imagination power, and can deter creativity, one of the indispensable skills in the 21st century. Mindfulness is another construct that is in line with creativity and its perspective to control anxiety is assured in literature. The proposed programs of mindfulness can influence creativity positively in the moment and over time. This is made possible by enhancing the level of the person's attention on daily activities which yields creative outcomes. In a world where stress and, often, distress undermine creativity, mindfulness emerges as an essential contributor to learners' success in educational practice. The current review focuses on young English as a foreign language (EFL) learners given that many believe stress and anxiety are commonplace among youth, leading to a decrease in creativity. Research findings reveal that mindfulness enhances creativity. Therefore, the improvement of students' well-being can be achieved by gradually incorporating mindfulness into the educational domain. Considering the important role of these factors in the language learning process, the purpose of this review is to examine the possible interactional effect of mindfulness in relation to creativity, learners' anxiety, and boredom in the context of L2 education among young learners. This is followed by proposing some suggestions for future research, as well as pedagogical implications.

Insight into the boosted ZEN degradation over defective Bi2WO6 ultrathin layers: ROS-mediated mechanism and application in corn oil.

Establishing an effective and sustainable strategy for zearalenone (ZEN) degradation is of great significance to agricultural development and food safety. Herein, more than 98 % of ZEN (2 ppm) was photocatalytic degraded within 90 min over the oxygen-deficient Bi2WO6 ultrathin layers (BWO-U), along with the sharp elimination of biotoxicity to GES-1 cells. Theoretical calculations and characterizations revealed the ultrathin structure and oxygen vacancies endowed BWO-U with strengthened photoelectrochemical activity and O2-adsorption capacity, facilitating the generation of •O2- and 1O2 which play decisive roles in ZEN degradation. Furthermore, a possible mechanism was proposed based on nine intermediates identified via LC-MS, including the steps of cis-trans isomerization, oxidation and cleavage. Eventually, the method also exhibited immense potential in reducing ZEN-contamination in corn oil, and made no significant impact on the quality of corn oil. This work might provide a feasible strategy to mitigate ZEN-contamination and cast a new light on the ROS-mediated mechanism.

Transcriptome-wide identification of NAC (no apical meristem/Arabidopsis transcription activation factor/cup-shaped cotyledon) transcription factors potentially involved in salt stress response in garlic.

Soil salinity has been an increasing problem worldwide endangering crop production and human food security. It is an ideal strategy to excavate stress resistant genes and develop salt tolerant crops. NAC (no apical meristem/Arabidopsis transcription activation factor/cup-shaped cotyledon) transcription factors have been demonstrated to be involved in salt stress response. However, relevant studies have not been observed in garlic, an important vegetable consumed in the world. In this study, a total of 46 AsNAC genes encoding NAC proteins were identified in garlic plant by transcriptome data. Phylogenetic analysis showed that the examined AsNAC proteins were clustered into 14 subgroups. Motif discovery revealed that the conserved domain region was mainly composed of five conserved subdomains. Most of the genes selected could be induced by salt stress in different tissues, indicating a potential role in salt stress response. Further studies may focus on the molecular mechanisms of the AsNAC genes in salt stress response. The results of the current work provided valuable resources for researchers aimed at developing salt tolerant crops.

Acupuncture decreases amygdala functional connectivity in subjective tinnitus.

Introduction: Subjective tinnitus is a common and intractable ear disease. The effectiveness of acupuncture in the treatment of subjective tinnitus has been confirmed, but its mechanism of action is not clear. The structures of the amygdala (AMYG) are mainly closely related to emotion in the human brain. This study aimed to investigate the changes in functional connectivity (FC) of AMYG in subjective tinnitus to elucidate the neural mechanism of acupuncture. Methods: Correlation scale scores of 26 patients with subjective tinnitus were collected, including Tinnitus Evaluation Questionnaire (TEQ), Tinnitus Handicap Inventory (THI) and Visual Analog Scale (VAS). Meanwhile, rs-fMRI data were collected before and after acupuncture treatment in the patients, and in healthy controls (HC) matching the patient's gender and age. Then, AMYG was selected as region of interest to perform FC analysis. Finally, FC patterns of AMYG were first compared between patients with subjective tinnitus and HC, and then within subjects pre-acupuncture and post-acupuncture. Simple linear regression models between correlation scale scores and FC-values were established as well. Results: Acupuncture treatment relieved the severity of tinnitus. With the acupuncture treatment, the total THI score, TEQ score, and VSA score of patients were significantly lower than before (p < 0.05). Compared with HC, FC of tinnitus patients between AMYG and right inferior temporal gyrus and right precuneus significantly decreased before acupuncture (voxel p < 0.001, cluster p < 0.05, corrected with GRF), while FC of tinnitus patients between AMYG and left superior frontal gyrus and right superior temporal gyrus significantly decreased after acupuncture treatment (voxel p < 0.001, cluster p < 0.05, corrected with GRF). FC of tinnitus patients between the AMYG and right superior frontal gyrus and left paracingulate gyrus showed significant decrease after acupuncture treatment (voxel p < 0.001, cluster p < 0.05, corrected with GRF). Besides, the linear regression models of the effect of THI on FC and VAS on FC performed were statistically significant (p < 0.05). Discussion: The findings demonstrate that acupuncture can decrease FC of AMYG, which could be positively correlated with the relief of tinnitus symptoms. This result suggests that acupuncture stimulation can effectively relieve the severity of tinnitus by decreasing FC of AMYG in subjective tinnitus patients.

[Bibliometric analysis on key elements of clinical application of acupoint catgut embedding therapy in recent ten years].

OBJECTIVE: To analyze the characteristics of acupoint catgut embedding methods, tools, catgut types, and the treatment cycles in the clinical research in recent ten years both at home and abroad, so as to summarize its regularities and to provide technical references for further studies. METHODS: Articles about clinical researches on catgut embedding therapy published in recent ten years (from January 1, 2010 to December 31,2020) were retrieved from the databases of CNKI, Wanfang, VIP, and PubMed by using key words of "acupoint embedding" "acupoint catgut embedding" and "catgut implantation at acupoint". According to the inclusion and exclusion criteria, a new database was established for analyzing the data mentioned above. RESULTS: 1) A total of 1 196 articles were collected, including 15 English articles and 1 181 Chinese articles, presenting a fluctuating increasing trend in recent ten years. 2) The commonly used acupoint embedding methods included disposable catgut embedment needle method (399 times, 38.89%) and disposable syringe needle catgut embedding method (347 times, 33.82%), for which two or multiple methods were mentioned in the same one article. 3) The most frequently used top two tools for catgut embedding were the dispo-sable catgut embedment needle (463 times, 43.03%) and disposable syringe needle (406 times,37.73%), with a significant increase in the application of disposable syringe needle. The most commonly used size of tools included No. 7 (283 times, 39.86%), No. 9 (196 times, 27.61%) and No. 8 (109 times, 15.35%). 4) The most frequently implanted surgical suture was still the common catgut (671 times, 58.15%) despite of a reduction in clinical application year by year, and the types of the implanted suture materials were gradually enriched since 2018, such as the absorbable surgical suture, polyethylprolactide(PGLA), collagen protein thread, polydioxanone(PPDO), etc. The commonly used implanted catgut size was 3-0 (227 times, 30.15%), 2-0 (176 times, 23.37%), 4-0 (131 times, 17.40%), 0 (103 times, 13.68%), with the commonly used catgut length being 1 cm (332 times, 35.55%), 1.5 cm (103 times, 11.03%), 1-2 cm (92 times, 9.85%) and 2 cm (92 times, 9.85%). 5) The intervals of the catgut implantation were 7 days (313 times, 28.95%), 14 days (262 times, 24.24%), 10 days (174 times, 16.10%), and 15 days (162 times, 14.99%). CONCLUSION: In recent ten years, clinical research on acupoint catgut embedding is growing rapidly, and the embedding methods, tools, implanted sutures, and embedding intervals are various, which may provide certain technical references for the future researches and suggest an urgent need of formulation of the standardized and unified standards in this field.

Light therapy for sleep disturbances in older adults with dementia: a systematic review, meta-analysis and meta-regression.

BACKGROUND: Sleep disturbances in older adults with dementia are common. Light therapy may help in regulating their sleep or wake cycle. However, data in the literature on the effectiveness of light therapy for the people with the said condition remain inconclusive. Thus, further research is warranted. OBJECTIVES: This review aims to synthesize the best available evidence on the effectiveness of light therapy in reducing sleep disturbances among older adults with dementia. METHODS: PubMed, Embase, Scopus, CINAHL, Cochrane Library, ALOIS, PsycInfo, Web of Science, ProQuest, OpenGrey, various trial registries and different journals specializing on sleep were searched without limitations on the year of publication. Cochrane's Risk of Bias Tool version 1 and GRADE criteria were used to assess risk of bias and certainty of evidence, respectively. Meta-analysis and meta-regression analyses were conducted using Stata software. RESULTS: A total of 18 randomized controlled trials (RCTs) involving 1012 older persons with dementia were included. The meta-analysis revealed that light therapy significantly reduced night-time awakenings (p = 0.04), enhanced sleep quality (p = 0.01) and increased relative amplitude (p = 0.01) with a small to medium effect (g = 0.26-0.43). Subgroup analyses showed that studies conducted in the Western Pacific region had a larger effect size on sleep duration and efficiency than those conducted in other regions. Univariate random-effects meta-regression revealed that sample size was a significant covariate for the effect size of sleep duration and sleep efficiency. CONCLUSION: This study found that the majority of outcomes had a low level of certainty. Therefore, additional well-designed and large-scale trials must be conducted to achieve a more definitive conclusion.

Effects of dance therapy on non-motor symptoms in patients with Parkinson's disease: a systematic review and meta-analysis.

BACKGROUND: Parkinson's disease (PD) represents the second most common neurodegenerative disease. OBJECTIVE: To evaluate the effects of dance therapy (DT) aimed at improving non-motor symptoms in PD. METHODS: Studies were performed through PubMed, Web of Science, The Cochrane Library, Embase, and Science Direct from inception to October 27, 2021. The data were screened independently by two reviewers, and the quality of the papers was assessed using the Cochrane manual. The included studies were randomized controlled trials and quasi-randomized controlled trials, reporting random-effects standardized mean differences, and 95% confidence intervals as the effect size. I2 statistics were used to assess heterogeneity. The main outcomes included the Montreal Cognitive Assessment Scale (MOCA), Baker Depression Scale (BDI), Parkinson's Fatigue Scale (FPS-16), and Apathy Scale (AS). RevMan 5.3 software was integrated for meta-analysis. RESULTS: Nine literatures were analyzed for the meta-analysis with a total of 307 patients. Random effects showed that DT significantly improved cognitive of PD (MD = 1.50, 95% CI [0.52, 2.48], P = 0.0003; I2 = 51%). However, this meta-analysis demonstrated that dance therapy had no significance for improving depression (MD = - 1.33, 95% CI [- 4.11, 1.45], P = 0.35; I2 = 79%), fatigue (MD = 0.26, 95% CI [- 0.31, 0.83], P = 0.37; I2 = 0%), and apathy (MD = 0.07, 95% CI [- 2.55, 2.69], P = 0.96; I2 = 50%). CONCLUSION: The meta-analysis suggests that dance can improve cognitive function in PD.

Evaluating the effectiveness of interprofessional advanced cardiac life support training: a sequential mixed-methods approach.

Interprofessional advanced cardiac life support (IP-ACLS) training is a holistic learning experience; thus, our research team incorporated this training into an undergraduate programme. Considering that IP-ACLS training is a new paradigm in nursing education, evaluating its effectiveness is essential. This research aimed to (1) evaluate the effectiveness of this training on improving the perceived level of interprofessional collaboration, self-efficacy and emotion regulation and (2) explore the learning experience of nursing students during training. The study design adopted a sequential mixed-method approach comprising a two-group pretest and posttest design amongst 120 students, followed by nine focus group discussions. Quantitative results demonstrated significant improvements in the perceived level of interprofessional collaboration, self-efficacy and emotion regulation at post-intervention and follow-up. Qualitative data were collected through video recording and field notes. Thematic analysis was performed following the method of Braun and Clarke. Qualitative analysis of focus group transcripts identified three themes: synergistic partnership, clinical readiness and improving further training. Quantitative and qualitative results were integrated in accordance with the mixed data analysis framework. These results complemented one another. The training provided an authentic learning experience and a good steppingstone to nursing students who are preparing to work interprofessionally in the future.

Effect of Low-Frequency Electro-Acupuncture in Unmarried Women With Polycystic Ovary Syndrome: A Randomized Controlled Study.

Objectives: We aimed to evaluate the effect of low-frequency electro-acupuncture (EA) in unmarried women with polycystic ovary syndrome (PCOS). Design: A total of 54 women with PCOS were randomly assigned to either the acupuncture group (n=27) or the sham acupuncture group (control, n=27) for a total of 32 treatments over 16 weeks. In the acupuncture group 26 patients and in the control group 20 patients completed the trial. Outcome Measures: Main measures were androgen levels including 17-α-hydroxyprogesterone (17-α-OHP), androstenedione (A2), testosterone (T) and dehydroepiandrosterone (DHEA) at 0, 24 and 48 hours after stimulation with a dose of human chorionic gonadotropin (HCG). Other measures included body mass index, waist-to-hip ratio, sex hormone levels, etc. Results: After treatment, there was no significant difference in the main measures between the 2 groups (P > .05), except for the DHEA level at 0 h of HCG stimulation (P = .024) and acne score (P < .05). Comparison within the acupuncture group found that 17-α-OHP and A2 levels at 0 h and DHEA levels at 24 h of HCG stimulation after treatment were significantly decreased (P < .05), whereas T levels at 24 h were significantly increased (P < .05). Comparison within the control group showed 17-α-OHP level at 0 h and 17-α-OHP and A2 and DHEA levels at 24 h after treatment were significantly lower (P < .05). In addition, weight, BMI, HCG and Ferriman-Gallwey score in the acupuncture group and LH/FSH ratio was significantly reduced in the control group. Conclusion: Traditional EA is slightly more effective than sham acupuncture in reducing DHEA secretion and the acne score. Meanwhile, sham acupuncture is not completely ineffective. The specific mechanism of the two may be different.

Impact of Low Frequency Electro-acupuncture on Glucose and Lipid Metabolism in Unmarried PCOS Women: A Randomized Controlled Trial.

OBJECTIVE: To explore the effect of electro-acupuncture (EA) on glucose and lipid metabolism in unmarried patients with polycystic ovary syndrome (PCOS). METHODS: Fifty-four PCOS patients were equally randomized into true acupuncture group and sham acupuncture group (control) for totally 16 weeks of treatment by random method with a computerized randomization program. Patients in true acupuncture group accepted traditional acupuncture methods with EA and two sets of acupoint groups were used alternatively. The first set consisted of Zhongji (CV 3), Qihai (CV 6), Guilai (ST 29), Sanyinjiao (SP 6), Yinlingquan (SP 9), Hegu (LI4) and Baihui (GV 20), and the second set consisted of Tianshu (ST 25), ST 29, CV 3, CV 6, SP 6, Taichong (LR 3), Neiguan (PC) 6 and GV 20. Patients in the sham acupuncture group accepted shallow acupuncture methods through EA without electricity at 4 non-meridian points in each shoulder and upper arm. Outcome measures included body mass index (BMI), waist-hip-ratio (WHR), oral glucose tolerance test (OGTT), insulin release test, glucose and lipid metabolism indicators such as total cholesterol (TC), triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, adiponectin, leptin, visfatin, resistin, and interleukin (IL-6). RESULTS: Twenty-six subjects in the true acupuncture group and 20 subjects in the sham group completed the clinical trial. After 16 weeks of treatment, no significant difference in the outcome measures were observed between the two groups (P>0.05). However, as compared with baseline data, a reduction in weight, BMI, hipline, WHR, fasting glucose, homeostatic model assessment of insulin sensitivity, visfatin and HDL-C, and an increase in resistin and IL-6 were observed in the true acupuncture group (P<0.05). In addition, a reduction in visfatin and an increase in TC were also observed in the sham group (P<0.05). CONCLUSIONS: Acupuncture may have a beneficial effect in the treatment of PCOS by improving glucose and lipid metabolism. Moreover, the sham acupuncture may be not completely ineffective. Sham acupuncture may improve some of the aspects of the glucose and lipid metabolism of PCOS patients through a placebo effect. (Registration Nos. ChiCTR-TRC-12002529 and NCT01812161).

A comparison of the effects of fire needle and routine acupuncture for myofascitis: A protocol for systematic review and meta-analysis.

BACKGROUND: Myofascitis is a common disease in clinic. The main cause of the disease is aseptic inflammation of local muscles and connective tissues such as myofascial, which can be manifested as paralysis, distension, and other discomfort, local muscle stiffness, spasm or palpable strain-like nodules. Chinese medicine ascribes it to "bi disease" and "Arthralgia disease," while Western medicine believes that the disease is mainly due to local muscle and fascia edema and exudation caused by trauma or long-term strain, forcing nerves to jam and producing pain and other abnormal feelings. Although the disease is not life-threatening, the pain and distension caused by local inflammatory stimuli can affect the patient's daily life and sleep quality. The purpose of this systematic review is to evaluate the efficacy of fire needle vs routine acupuncture in the treatment of myofascitis. METHODS: Randomized controlled trials (RCTS) of fire needle vs routine acupuncture for myofascial inflammation will be comprehensively searched from inception to September 2020 on PubMed, Embase, Cochrane Library, China Biomedical Literature (CBM), China National Knowledge Infrastructure (CNKI), Chongqing VIP (CQVIP), and Wanfang. Additionally, RCT registered sites, including http://www.ClinicalTrials.gov and http://www.chictr.org.cn, also will be the search. Visual analogue scale (VAS) was used to score the pain before and after treatment. The primary outcome will be to compare the difference in pain scores between the 2 interventions. Two independent authors filtered the literature in the above database, extracted the data, and cross-checked it. RESULTS: This study will offer a reasonable comprehensive evidence for the treatment of myofascitis with fire needle. CONCLUSION: The conclusion of this study will provide evidence to judge the effectiveness of fire needle on myofascitis. REGISTRATION NUMBER: INPLASY202080034.

Acupuncture for drooling in children with cerebral palsy: A protocol for systematic review.

BACKGROUND: The aim of this study is to provide the methods used to evaluate the effectiveness and safety of acupuncture therapy for treating drooling in children with cerebral palsy. METHODS AND ANALYSIS: A comprehensive search of Pubmed, Embase, Cochrane Central Register of Controlled Trials, Web of Science, 4 Chinese databases (China National Knowledge Infrastructure, Chinese Biomedical Literatures database, Wan-Fang Database and Chinese Science and Technology Periodicals will be conducted to identify randomized controlled trials of acupuncture for treating children with cerebral palsy salivation with no restriction on time or language. The primary outcome of this systematic review will be the effective rate. The risk of bias will be implemented according to Cochrane Handbook for Systematic Reviews of Interventions. We will conduct the meta-analysis to synthesize the evidence for each outcome, if possible. The heterogeneity will be evaluated statistically using the χ2 test and the I2 statistic. The random-effect model will be used to provide more conservative results, if significant heterogeneity is identified (I2 > 50% or P < .10). ETHICS/DISSEMINATION: Our findings will be disseminated in a peer-reviewed journal and at conference meetings. It is not necessary for formal ethical approval as no primary data are collected. TRIAL REGISTRATION NUMBER: INPLASY2020110024.

Effect of electroacupuncture on the kisspeptin system in a pubertal rat model of polycystic ovary syndrome.

OBJECTIVE: To explore the effects and mechanism of action of electroacupuncture (EA) in a rat model of pubertal polycystic ovary syndrome (PCOS). METHODS: Female offspring of Sprague-Dawley rats receiving dihydrotestosterone (DHT) during pregnancy (days 16-19), as a model of prenatal androgenization, were divided randomly into three groups: model group (M), EA group, and sham acupuncture (SA) group (n = 8 each). A normal (N) group comprising female offspring of healthy pregnant rats not receiving DHT (n = 8) was added. EA was administered at CV6 and bilateral SP6/ST36 with 2 Hz frequency and 2 mA intensity. SA consisted of superficial needling at different locations without electrical stimulation. RESULTS: EA improved the disturbed estrous cycles, while it could not be concluded that SA was effective in this respect. EA improved ovarian morphology including the number of corpora lutea and area of the ovary, whereas SA did not. However, both EA and SA attenuated the increased luteinizing hormone and decreased estradiol and gonadotropin-releasing hormone levels in the serum of PCOS model rats. Levels of testosterone, follicle-stimulating hormone, and progesterone did not significantly differ between groups. EA and SA alleviated the upregulation of kisspeptin protein and mRNA levels in the hypothalamus and kisspeptin protein level in the arcuate nucleus (ARC). No differences were found between groups in protein or mRNA expression of dynorphin (DYN) or neurokinin B (NKB) in the hypothalamus. Co-expression of kisspeptin, NKB, and DYN were observed in ARC. The GnRH level in the median eminence decreased and could be rescued by EA and SA. Intriguingly, kisspeptin levels in the granulosa cells of the ovary decreased in the model group and could be rescued by EA but not SA. Levels of kisspeptin, NKB, and DYN protein and mRNA in the ovary did not differ between any groups. CONCLUSION: Both EA and SA appeared to improve symptoms of PCOS at puberty by modulating the kisspeptin system in the hypothalamus. EA also had an effect on ovarian kisspeptin expression and a more comprehensive effect with respect to improving PCOS at puberty than SA.

Efficacy of low-level light therapy for improving healing of diabetic foot ulcers: A systematic review and meta-analysis of randomized controlled trials.

Diabetic foot ulcers are prevalent among patients with diabetes and negatively affect mortality and life expectancy. This study aimed to synthesize and systematically review the best evidence to assess the efficacy of low-level light therapy in improving healing of diabetic foot ulcers. We search CINAHL, Cochrane Library, EMBASE, ProQuest, PubMed, Scopus, and Web of Science from inception until September 30, 2019. Meta-analysis was performed using the Comprehensive Meta-analysis 3.0 software. Overall effect was measured using Hedges' g and determined using the Z-statistic at a significance level of P < .05. Heterogeneity was assessed using χ2 and I2 statistics. Twelve randomized controlled trials were included. Meta-analysis revealed that 30.90% of the ulcer area was significantly reduced in the therapy group compared with the control group (Z = 3.95, P < .001) with a very large effect (g = 2.81). A 4.2 cm2 reduction of the ulcer area was observed in the therapy group compared with the control group (Z = 2.17, P = .03) with a very large effect (g = 1.37). In addition, diabetic foot ulcers in the therapy group was 4.65 times more likely to heal completely than those in the control group (Z = 3.02, P = .003). Low-level light therapy accelerates wound healing and reduces the size of diabetic foot ulcers. However, our review does not allow any recommendation for the best treatment parameters required to achieve improved healing. Future trials need to include a good design and large sample size in defining the optimal treatment parameters for ulcers of different sizes.

Efficacy of five-element music interventions in perinatal mental health and labor pain: A meta-analysis.

OBJECTIVE: To systematically review the efficacy of five-element music interventions in perinatal mental health and labor pain. To provide evidence for future research on Chinese Traditional Music Interventions. METHODS: An electronically search was conducted in Web of Science, PubMed, EMbase, The Cochrane Library, CNKI databases, WanFang Data and VIP Database for Chinese Technical Periodicals from inception to January 07, 2020 to collect randomized controlled trials (RCTs) on five-element music interventions for prenatal, perinatal and postpartum women. Literature screening, data extraction, and the risk of bias assessment of all eligible studies were conducted by two reviewers independently. Then, meta-analysis was performed by RevMan 5.3 software. RESULTS: A total of 13 RCTs involving 2387 patients were included. The results of meta-analysis showed that five-element music could significantly improve the depression levels (SMD = -2.03, 95%CI: -2.88 to -1.19, P < 0.00001), anxiety levels (SMD = -3.49, 95%CI: -4.47 to -2.24, P < 0.00001) and severe anxiety rate (OR = 0.42, 95%CI: 0.19 to 0.94, P = 0.04) of perinatal women. Additionally, five-element music produced significant effects on labor pain (MD = -0.67, 95%CI: -0.82 to -0.52, P < 0.00001), labor duration (MD = -0.85, 95%CI: -1.07 to -0.63, P < 0.00001), the hemorrhage 2 h after parturition (MD = -19.55, 95%CI: -35.56 to -3.54, P = 0.02) and the Serum DYN expression level (MD = 1.32, 95%CI: 0.23 to 2.40, P = 0.02). CONCLUSIONS: Five-element music may be efficacious in improving perinatal women' depression, anxiety, labor pain, labor duration, the hemorrhage 2 h after parturition and the Serum DYN expression level. Because of the limitation of quantity and quality of included studies, more high-quality studies were needed to confirm the above conclusion.

Anti-influenza virus phytochemicals from Radix Paeoniae Alba and characterization of their neuraminidase inhibitory activities.

ETHNOPHARMACOLOGICAL RELEVANCE: Bai Shao (Radix Paeoniae Alba, BS), the root of Paeonia lactiflora Pall., in ancient China was used for Wen Bing (Warm Disease) treatment. Wen Bing has the symptoms of influenza. Ethanol extract of the root has recently been shown to possess anti-influenza activity. However, the active compounds have not yet been identified. AIM: We showed that BS aqueous extract was potent in inhibiting influenza A virus in infected cells. We aimed to isolate the bioactive compounds and characterize the anti-influenza mechanism. MATERIALS AND METHODS: Plaque reduction assay was performed for fractions isolated from BS. Hemagglutination inhibition assay and neuraminidase inhibition assay were performed to find the target protein. Molecular docking and reverse genetics were used to confirm the action site of gallic acid on the neuraminidase protein. RESULTS: We identified three tannin compounds gallic acid (GA), methyl gallate (MG) and pentagalloylglucose (PGG) in BS aqueous extract that could inhibit the replication of influenza A virus in MDCK cells. While only PGG was found to inhibit the influenza virus-induced hemagglutination of chicken erythrocytes, all three compounds significantly reduced the activity of the neuraminidase. The results from molecular docking and reverse genetics showed that GA interacted with Arg152 of neuraminidase protein. CONCLUSION: Three compounds GA, MG and PGG isolated from BS were found to inhibit influenza A virus in MDCK cells. GA interacts with amino acid Arg152 of the viral neuraminidase. Our study identified anti-influenza compounds of BS and demonstrated their antiviral mechanism, thus providing scientific evidence for using this herb for clinical treatment.
