[Effects of Streptomyces pactum Act12 on root morphogenesis and medicinal quality of Codonopsis pilosula]. / 密旋链霉菌Act12å¯¹å šå‚æ ¹ç³»å½¢æ€åŠè¯æå“è´¨çš„å½±å“.

As a kind of tonic Chinese medicine with dual use in medicine and food, there is a large market demanding for Codonopsis pilosula. Taking one-year-old C. pilosula seedlings as materials, we conducted a field experiment to examine the effect of compound fertilizer (750 kg·hm-2), organic fertilizer (15 t·hm-2) and Streptomyces pactum Act12 agent (9 t·hm-2 Act12+10 t·hm-2 organic fertilizer) treatments on root morphology, secondary metabolite content and expression level of lobetyolin metabolic pathway gene of C. pilosula, to clarify the effects of three fertilizers on the root morphology and medicinal quality. Compared to the control (10 t·hm-2 organic fertilizer, conventional fertilization), three fertilization treatments could promote root growth and formation. All fertilization treatments promoted the accumulation of C. pilosula polysaccharides and secondary metabolites. Act12 agent significantly increased the content of lobetyolin, atractylenolideIII, and 5-hydroxymethylfurfural. The qRT-PCR analysis indicated that three fertilization treatments increased the expression level of lobetyolin metabolic pathway genes, with Act12 agent treatment showing the most significant effect. Pearson correlation analysis demonstrated that the expression level of CpHCT and CpFAD genes was significantly positively correlated with atractylenolide III content. In conclusion, three fertilization treatments could effectively improve the yield and quality of C. pilosula. Among the three treatments, Act12 agent performed better than that of compound fertilizer and organic fertilizer, which was an effective measure to increase the yield and quality of C. pilosula.

Trans-Anethole Alleviates DSS-Induced Ulcerative Colitis by Remodeling the Intestinal Flora to Regulate Immunity and Bile Acid Metabolism.

Ulcerative colitis (UC) is the most common inflammatory bowel disease (IBD); it is incurable, and the treatment is expensive. Trans-anethole (TA), the main component of fennel, exhibits various biological activities. An increasing number of studies have demonstrated the efficacy of herbal active ingredients in the treatment of UC. This study aimed to investigate the effect and mechanism of TA in UC. In this study, we have experimented on mice with dextran sulfate sodium salt (DSS)-induced UC. The TA group was gavaged with 62.5 mg/kg TA by gavage once daily on days 8-14. To observe the effect of TA on the colon tissue, various investigations were performed, including western blot and immunohistochemistry for intestinal barrier protein expression, TUNEL staining for apoptosis, western blot, and ELISA for inflammation level, flow cytometry for Th17/Treg, LC-MS for blood bile acid content, GC-MS for blood fatty acid content, and 16s RNA for intestinal contents. TA alleviated weight loss in mice with UC; increased colon length; alleviated intestinal mucosal damage; upregulated claudin-1, occludin, and ZO-1 protein expression levels; reduced inflammatory factors in the colon and serum; and alleviated apoptosis. TA reduced fatty acid and bile acid levels by inhibiting colony abundance and reducing Th17/Treg cell differentiation in the colon. We found that TA alleviates DSS-induced UC by remodeling the intestinal flora to regulate immunity and bile acid metabolism.

[Effect of moxibustion of "Ganshu"(BL18) and "Shenshu" (BL23) on musculoskeletal interaction in osteoporosis rats].

OBJECTIVE: To observe the effect of moxibustion of "Ganshu" (BL18)and "Shenshu" (BL23) on bone mineral density (BMD), biomechanics, bone metabolism and musculoskeletal morphology of osteoporosis (OP) rats, so as to explore its mechanism underlying treatment of OP via bone-muscle interaction. METHODS: Thirty-two female SD rats were randomly divided into sham operation, OP model, moxibustion and medication (nilestriol) groups, with 8 rats in each group. For rats of the sham operation group, a small amount of fat around the ovaries was removed, and those of the other 3 groups received removal of bila-teral ovaries for establishing OP model. Moxibustion was applied to bilateral BL18 and BL23 for 30 min, once every other day, 3 times a week for 12 weeks. Rats of the medication group received gavage of nilestriol (1 mg/kg) once a week for 12 weeks.After the interventions, a dual-energy absorptiometry was used to determine the BMD and bone mineral content of the rats' right femur and the fourth lumbar vertebrae under anesthesia, and three-point bending test used to detect the biomechanical properties (including load, displacement, stiffness) of the right femur. The levels of serum type I collagen C-terminal peptide (CTX-I), acid-resis-tant tartrate phosphatase (TRACP) and estradiol (E2) were determined using enzyme-linked immunosorbent assay, and histopathological changes of the left femur and the quadriceps observed after hematoxylin-eosin (H.E.) staining. RESULTS: Compared with the sham operation group, the BMD and bone mineral contents of the right femur and the fourth lumbar vertebra, the load and stiffness of the right femur, and concentration of serum E2 were significantly decreased (P<0.01, P<0.05), and the displacement of the right femur, and concentrations of serum CTX-Ⅰ and TRACP notably increased in the model group (P<0.01). After the interventions, the decreased levels of BMD and bone mineral contents, the load and stiffness and concentration of serum E2, and the increased levels of the displacement, and concentrations of serum CTX-Ⅰ and TRACP were all reversed by both moxibustion (except the bone mineral content of the fourth lumbar vertebra) and medication (P<0.01,P<0.05). No signi-ficant differences were found between moxibustion and medication in up-regulating the levels of BMD and bone mineral contents, the load and stiffness (except serum E2) and down-regulating the levels of the displacement, and concentrations of serum CTX-Ⅰ and TRACP (P>0.05). H.E. staining revealed that rats in the sham operation group showed mild thinness of the bone cortex, uneven thickness of trabecular bone, with distortion, fracture and osteoporosis of the left femur, and different size of rhabdomyocytes in the right quadriceps femoris muscle, with obvious proliferation of interstitial fibrous tissue and inflammatory cell infiltration, which were relatively and clearly milder in both moxibustion and medication groups. CONCLUSION: Moxibustion of BL18 and BL23 can increase the BMD and bone mineral content, improve biomechanical performance, adjust bone metabolism, and mitigate bone and the attached muscle histopathological changes in OP rats, suggesting that modulating interaction between bones and muscles is probably one of the ideas in the treatment of OP.

[Electroacupuncture on motor function in patients with primary osteoporosis: a randomized controlled trial].

OBJECTIVE: To observe the effect of electroacupuncture on motor function and muscle state in patients with primary osteoporosis (POP). METHODS: A total of 60 female patients with POP were randomized into an observation group (30 cases, 1 case dropped off) and a control group (30 cases, 1 case dropped off). On the basis of adjusting lifestyle, caltrate was given orally in the control group, 2 pills a day for 4 weeks. On the basis of the treatment in the control group, electroacupuncture was applied at Zusanli (ST 36), Yanglingquan (GB 34), Ganshu (BL 18), Pishu (BL 20), Shenshu (BL 23), etc. in the observation group, with disperse-dense wave of 2 Hz/10 Hz in frequency, once every other day, 3 times a week for 4 weeks. The time of timed up-and-go test (TUGT) and the value of 10 m maximal walking speed (10 m MWS) before and after treatment were compared in the two groups, and the Young's modulus values of bilateral multifidus muscles in prone position and sitting position before and after treatment were compared by real-time shear wave elastography (SWE) in the two groups. RESULTS: After treatment, the TUGT time was decreased compared before treatment in the observation group (P<0.01), and that in the observation group was shorter than the control group (P<0.01). After treatment, the value of 10 m MWS test was increased compared before treatment in the observation group (P<0.05). After treatment, the Young's modulus values of bilateral multifidus muscles in prone position and sitting position were increased compared before treatment in the observation group (P<0.01); except for the left side in sitting position, the Young's modulus values of multifidus muscles in the observation group were higher than those in the control group (P<0.01, P<0.05). CONCLUSION: On the basis of oral caltrate, electroacupuncture can improve the motor function and muscle state in patients with POP.

Acupuncture combined with traditional Chinese medicine e-aid cognitive behavioral therapy for insomnia (TCM-eCBT-I) for chronic insomnia: study protocol for a randomized controlled trial.

INTRODUCTION: The incidence of insomnia is getting higher and higher. Long-term insomnia seriously affects people's health. Drug use is usually accompanied with adverse events. Both acupuncture and cognitive behavioral therapy for insomnia (CBT-I) have been proven to be safe and effective non-pharmacological treatments for insomnia. As the insomniacs' bad sleep behavior and wrong cognition have not been effectively corrected, acupuncture has a quick effect, high patient compliance but unstable long-term efficacy, while CBT-I is complex, time-consuming, and expensive; additionally, patient compliance is low, and the number of trained therapists is limited, making it difficult to carry out. Therefore, this study aims to use the insomnia TCM system to construct a convenient and feasible traditional Chinese medicine e-aid cognitive behavioral therapy for insomnia (TCM-eCBT-I) for Chinese people, and combine the advantages of acupuncture and TCM-eCBT-I for maintaining long-term efficacy, and three treatments will be evaluated to provide clinicians with a more effective clinical protocol METHODS AND ANALYSIS: This study is a single-center, open-label, randomized controlled trial. Ninety subjects will be recruited and randomly assigned to three groups: the acupuncture group, the TCM-eCBT-I group, and the acupuncture combined with TCM-eCBT-I group, in a ratio of 1:1:1. We will evaluate the Pittsburgh Sleep Quality Index (PSQI) and Dysfunctional Beliefs and Attitudes About Sleep Scale (DBAS), Insomnia Severity Index (ISI), sleep diary, Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), and Fatigue Scale-14 Scale (FS-14) scales. All adverse reactions will be assessed through the ADVERSE event table. All outcomes will be evaluated online at 0 weeks, 4 weeks, 8 weeks, 16 weeks, and 28weeks. ETHICS AND DISSEMINATION: This study has been approved by the Institutional Review Board of the Affiliated Hospital of Nanjing University of Chinese Medicine (2020 NL-018-02). Informed consent will be obtained from all the subjects. The results will be shared with sleep researchers, public, and relevant academic institutions through high-impact peer-reviewed publications.

[Clinical therapeutic effect on bronchial asthma by the observation of skin reaction after acupoint application based on chronic disease management platform of asthma].

OBJECTIVE: To compare the therapeutic effect on bronchial asthma between presence of skin reaction and the absence of skin reaction after acupoint application. METHODS: Sixty-one patients with bronchial asthma were treated with acupoint application during the hottest periods of summer ("dog days"). The acupoints included Dingchuan (EX-B 1), Feishu (BL 13), Xinshu (BL 15), Pishu (BL 20) and Shenshu (BL 23). The treatment was given once every 7 days, with the herbal plaster remained for 6 h each time, and 4 treatments were required totally. According to the local skin reaction after acupoint application, a skin reaction group (30 cases, 2 cases dropped off) and a non-skin reaction group (31 cases) were divided. Separately, before treatment and 1 year after treatment, using chronic disease management platform of asthma, the number of asthma attacks, the score of asthma control test (ACT) and the score of asthma quality of life questionnaire (AQLQ) were recorded online. Besides, the therapeutic effect was observed in the two groups 1 year after treatment. RESULTS: One year after treatment, the number of asthma attacks was reduced as compared with that before treatment in the patients of either group (P<0.001), the score of ACT and each domain in AQLQ, i.e. activity limitation, asthma symptoms, psychological state, reactions to stimuli and self-health care as well as the total scores of AQLQ were all increased as compared with those before treatment (P<0.001). The number of asthma attacks in the skin reaction group was less than the non-skin reaction group (P<0.05), the score of ACT and each domain of AQLQ and the total scores of AQLQ were all higher than the non-skin reaction group successively (P<0.05, P<0.01). The total effective rate was 82.1% (23/28) in the skin reaction group, better than 67.7% (21/31) in the non-skin reaction group (P<0.05). CONCLUSION: In treatment of acupoint application for bronchial asthma, the clinical therapeutic effect is better in the patients with local skin reaction after acupoint application. The chronic disease management platform of asthma is convenient for online evaluation.

[Effect of Tiaoshen needling on plasma melatonin and cortisol in patients with chronic insomnia].

OBJECTIVE: To observe the clinical efficacy of Tiaoshen needling (dredging Governor Vessel and regulating mind)in the treatment of chronic insomnia (CI) and its effect on plasma melatonin (MT) and cortisol (CORT) levels, so as to explore its underlying mechanism. METHODS: Sixty patients with CI were randomly divided into the treatment group and the control group, with 30 cases in each group. Both groups were given sleep hygiene education before treatment. Patients in the treatment group received acupuncture or electroacupuncture at Baihui (GV20), Shenting (GV24), Yintang (GV29), bilateral Shenmen (HT7) and Sanyinjiao (SP6). Patients in the control group received acupuncture or electroacupuncture at bilateral Shousanli (LI10), Futu (ST32) and Feiyang(BL58). Both groups were treated every other day, 3 times a week, for a total of 4 weeks. Before and after treatment, Pittsburgh sleep quality index (PSQI) and fatigue severity scale (FSS) were used to evaluate sleep qua-lity and daytime fatigue, the plasma MT and CORT levels were measured by enzyme-linked immunosorbent assay. RESULTS: Compared with before treatment, the PSQI scores and total FSS score of the treatment group decreased significantly (P<0.01，P<0.05), and the plasma MT content increased and CORT decreased significantly in the treatment group (P<0.01)，while the sleep-onset time score, sleep disturbance score and the PSQI total score of the control group decreased significantly (P<0.05). Compared with the control group, the PSQI sleep disorder score and total score, and the total FSS score as well as plasma CORT level were significantly down-regulated (P<0.01，P<0.05), while the plasma MT content was up-regulated (P<0.05) in the treatment group. CONCLUSION: Tiaoshen acupuncture can significantly improve the sleep quality of patients with CI and relieve daytime fatigue, which may be related to the increase of plasma MT content in patients with CI, thereby inhibiting the excessive activation of the hypothalamic-pituitary-adrenal axis.

Effect of Acupuncture on Cognitive Function of Insomnia Patients Compared with Drugs: A Protocol for Meta-analysis and Systematic Review.

Insomnia, one of the most common sleep disorders, is thought to have an adverse effect on cognitive function. At the same time, people with cognitive dysfunction are more prone to insomnia. At present, pharmacotherapy is the main treatment for insomnia, but there are some shortcomings such as poor long-term efficacy and potential dependence. There is some evidence that acupuncture has some advantages in alleviating insomnia and improving cognitive function. This study is aimed at investigating the effects of acupuncture and drugs on cognitive function in patients with insomnia and evaluating the efficacy and safety of these two interventions, providing strong evidence for clinical decision-making. The study will retrieve eight major databases: China National Knowledge Infrastructure, Wanfang Database, VIP Database for Chinese Technical Periodicals, SinoMed, PubMed, Web of Science, Embase, and Cochrane Library. Dissertations, conference papers, and ongoing experiments will also be retrieved for supplement. Literature screening and data extraction will be completed by two authors independently (JJ and X-QW). If there were any disagreements, they would be discussed or referred to a third person for adjudication (W-ZW). Authors will use Cochrane risk of bias tool to assess the included studies. The Review Manager Statistical (RevMan) software is used to conduct the statistical process of meta-analysis, and funnel plot is used to evaluate reporting biases. The Grading of Recommendations Assessment Development and Evaluation (GRADE) Profiler can be used to be aware of the quality of evidence.

The efficacy of acupuncture on the sleep structure of patients with insomnia: A systematic review and meta-analysis.

This study aims to evaluate the efficacy of acupuncture on the sleep structure of patients with insomnia, so as to provide a valuable basis for the effectiveness of acupuncture in the treatment of insomnia. We conducted searches based on MeSH terms and free words in Cochrane Library, PubMed, Web of science, CKNI (China Knowledge Resource Integrated Database), WanFang Database, and Chongqing VIP Information from the inception of these database until 10 July 2020 for randomized controlled trials (RCTs) that investigated acupuncture treatment in patients with insomnia, and pertinent details of the results were saved. Comprehensive analysis showed that: (1) compared with the Western medicine groups, the acupuncture groups showed significant advantages in reducing the percentage of N1 sleep stage and N2 sleep stage, as well as increasing that of N3 sleep stage and REM sleep stage. However, no significant difference was found in increasing the effective rate, reducing total PSQI score, improving the total sleep time, reducing sleep latency, and improving sleep efficiency between the Western medicine groups and the acupuncture groups. (2) Compared with the sham acupuncture groups, the acupuncture treatment showed advantages in increasing the effective rate, reducing Pittsburgh Sleep Quality Index (PSQI) score, increasing the total sleep time, and improving sleep efficiency. However, no significant difference was observed between the sham acupuncture groups and the acupuncture groups with regard to reducing sleep latency, the percentage of N1 sleep stage and N2 sleep stage, as well as increasing that of N3 sleep stage and REM sleep stage.

[Effect of Tongdu Tiaoshen acupuncture on serum GABA and CORT levels in patients with chronic insomnia].

OBJECTIVE: To observe the clinical effect of Tongdu Tiaoshen acupuncture on chronic insomnia, and explore its possible mechanism. METHODS: A total of 60 patients with chronic insomnia were randomly divided into an observation group (30 cases) and a control group (30 cases, 1 case dropped off ). The observation group was treated with Tongdu Tiaoshen acupuncture at Baihui (GV 20), Yintang (GV 29), Shenting (GV 24), etc. once every other day, 3 times a week. The control group was treated with estazolam tablets (1 mg) orally before going to bed every night. The treatments of both groups were required 4 weeks. The Pittsburgh sleep quality index (PSQI) scores, serum gamma-aminobutyric acid (GABA) and cortisol (CORT) levels were observed before and after treatment in the two groups, and the clinical effect was compared. RESULTS: After treatment, the sleep quality, day dysfunction scores of PSQI in the observation group and the falling asleep time, sleep time, sleep efficiency, sleep disturbance scores and total scores of PSQI in the two groups were lower than before treatment (P<0.01, P<0.05). After treatment, the daytime dysfunction score of PSQI in the observation group was lower than that in the control group (P<0.05). After treatment, the serum GABA levels in the two groups were higher than before treatment (P<0.05), and the serum CORT levels were lower than before treatment (P<0.01). The total effective rate was 90% (27/30) in the observation group and 93.1% (27/29) in the control group, the difference was not statistically significant (P>0.05). CONCLUSION: Tongdu Tiaoshen acupuncture has the same effect as western medication estazolam tablets in the treatment of patients with chronic insomnia, and has little effect on daytime dysfunction. The mechanism may be related to the increase of serum GABA level and the inhibition of the hyperactivation of hypothalamus-pituitary-adrenal (HPA) axis.

Comparative Utility of Acupuncture and Western Medication in the Management of Perimenopausal Insomnia: A Systematic Review and Meta-Analysis.

BACKGROUND: Many women with perimenopausal insomnia (PMI) have sought alternative therapies such as acupuncture because of concerns about risks associated with hormone replacement therapy (HRT) and/or psychotropic drugs. This systematic review aimed to clarify if acupuncture alone or combined with standard Western pharmacotherapy (HRT and/or psychotropic drugs) is more effective in ameliorating PMI in comparison to pharmacotherapy alone. METHODS: Randomized controlled trials (RCTs) of PMI treatment via acupuncture alone or combined with Western pharmacotherapy versus Western pharmacotherapy were searched for from eleven databases from inception to March 2020. Cochrane criteria were followed. RESULTS: Fifteen studies involving 1410 women were analyzed. Meta-analysis indicated that acupuncture significantly reduced the global scores of Pittsburgh Sleep Quality Index (PSQI) [MD = -2.38, 95% CI (-3.38, -1.37), p < 0.01] and Kupperman Index [MD = -5.95, 95% CI (-10.68, -1.21), p = 0.01], compared with hypnotics. Acupuncture combined with hypnotics was more effective than hypnotics alone in decreasing PSQI scores [MD = -3.13, 95% CI (-5.43, -0.83), p < 0.01]. Too few RCTs were available to investigate the clinical efficacy differences between acupuncture and HRT/psychotropic drugs other than hypnotics. CONCLUSIONS: Despite limited evidence, in comparison to hypnotics, acupuncture was associated with significant improvements in PMI, and reductions of other menopausal symptoms. This finding suggests that acupuncture may be a useful addition to treatment for PMI.

[Effect of electroacupuncture on serum melatonin and dopamine in aged insomnia].

OBJECTIVE: To observe the clinical effect of electroacupuncture (EA) on aged insomnia, and explore its possible mechanism. METHODS: A total of 60 patients with aged insomnia were randomly divided into an EA group (30 cases) and a sham EA group (30 cases, 1 case dropped off). The patients in the EA group were treated with acupuncture at Baihui (GV 20), Yintang (GV 29), Shenmen (HT 7), Sanyinjiao (SP 6), Xinshu (BL 15) and Shenshu (BL 23), and EA was used at Baihui (GV 20) and Yintang (GV 29), with intermittent wave, 2 Hz in frequency. In the sham EA group, the acupoints and the EA connection acupoints were the same as those in the EA group, 2-3 mm in depth, but no current was connected. The intervention was given 30 min each time, once every other day, 3 times a week for 4 weeks in the both groups. Before and after treatment, the Pittsburgh sleep quality index (PSQI) and Montreal cognitive assessment (MoCA) scale were used to assess sleep quality and cognitive function, and serum melatonin (MT) and dopamine (DA) levels were detected. RESULTS: After treatment, the total score and sub-item scores of PSQI in the EA group were lower than those before treatment (P<0.01, P<0.05), among them, the sub-item scores of sleep quality, time to fall asleep, sleep time and sleep efficiency, daytime dysfunction and total score were all lower than those in the sham EA group (P<0.01, P<0.05). After treatment, the MoCA score and serum MT and DA levels in the EA group were higher than those before treatment (P<0.01), and the MoCA score and serum MT level in the EA group were higher than the sham EA group (P<0.01, P<0.05). CONCLUSION: Electroacupuncture can improve sleep quality and cognitive function in aged insomnia patients, and its mechanism may be related to regulating serum MT and DA levels.

[Effect of acupuncture at Tiaoshen acupoints on hyperarousal state in chronic insomnia].

OBJECTIVE: To observe the clinical effect of acupuncture at Tiaoshen (regulating the spirit) acupoints on chronic insomnia and hyperarousal state, and explore its possible mechanism. METHODS: A total of 60 patients with chronic insomnia were randomly divided into an acupuncture group (30 cases, 1 case dropped off) and a sham acupuncture group (30 cases, 1 cases dropped off). Both groups were given basic sleep health education. The acupuncture group was treated with acupuncture at Tiaoshen acupoints including Baihui (GV 20), Shenting (GV 24), Yintang (GV 29), Shenmen (HT 7) and Sanyinjiao (SP 6). The sham acupuncture group was treated with non-effective point shallow acupuncture. Both groups were treated once every other day, 3 times a week for 4 weeks. The Pittsburgh sleep quality index (PSQI) score, pre-sleep arousal scale (PSAS) score, hyperarousal scale (HAS) score, and serum gamma-aminobutyric acid (GABA) level before and after treatment were compared between the two groups. RESULTS: Compared before treatment, the sleep quality, time to fall asleep, sleep time, sleep efficiency, sleep disturbance, daytime dysfunction scores and total score of PSQI, various scores and total score of PSAS, and HAS score in the acupuncture group after treatment were decreased (P<0.05, P<0.01); in the sham acupuncture group, the time to fall asleep, daytime dysfunction scores and total score of PSQI, and cognitive arousal score of PSAS after treatment were decreased (P<0.05). After treatment, the sleep quality, time to fall asleep, sleep time, sleep efficiency, sleep disturbance, daytime dysfunction scores and total score of PSQI, various scores and total score of PSAS, and HAS score in the acupuncture group were lower than those in the sham acupuncture group (P<0.05, P<0.01). Compared before treatment, the serum GABA level in the acupuncture group were increased (P<0.05), and the serum GABA level in the acupuncture group was higher than that in the sham acupuncture group after treatment (P<0.05). CONCLUSION: Acupuncture at Tiaoshen acupoints can obviously improve the sleep and hyperarousal state of patients with chronic insomnia, and up-regulating serum GABA content is one of its possible mechanisms.

Can acupuncture improve objective sleep indices in patients with primary insomnia? A systematic review and meta-analysis.

BACKGROUND: The efficacy of acupuncture for treating primary insomnia (PI) has been explored in several meta-analyses where the outcomes measures were based on subjective self-reported sleep rating scales. Sleep state misperception is common in PI and self-reports underestimate sleep duration and quality. No systematic reviews or meta-analyses have investigated the efficacy of acupuncture in improving objective sleep measures in PI. OBJECTIVE: To perform a systematic review to determine whether objective sleep parameters are improved by acupuncture in patients with PI. METHODS: Randomized controlled trials treating PI via verum-acupuncture versus sham-/placebo-acupuncture or waitlist control were searched for in English [MEDLINE (via PubMed), Sciverse ScienceDirect, Cochrane Central Register of Controlled Trials (CENTRAL), AMED, Springer, EMBASE (Elsevier), Ebsco Medline, and PsycINFO (ProQuest)] and Chinese (SinoMed, CNKI, Wanfang and CQVIP) databases, from the dates of the databases' inception to January 2020. The parameters of polysomnography (PSG), actigraphy, or micromovement sensitive mattress/pillow sleep monitoring systems were considered as the primary outcome measures. Revman 5.3 and Stata 16.0 software were used to conduct the meta-analysis. Heterogeneity was examined by using I2 statistics and publication bias was assessed via Egger's test. RESULTS: Eleven studies involving 775 patients met the inclusion criteria. The results of meta-analysis suggested that acupuncture can increase total sleep time [MD = 55.29, 95%CI (29.16, 81.42), p < 0.01], increase sleep efficiency [MD = 8.96, 95%CI (3.97, 13.95), p < 0.01], decrease wake after sleep onset [MD = -49.54, 95%CI (-82.98, -16.09), p < 0.01], and reduce number of awakening times [MD = -6.29, 95%CI (-10.75, -1.82), p < 0.01] compared with either sham-/placebo-acupuncture or waitlist control. Subsequent analysis indicated a superior effect for verum-acupuncture in comparison with sham-/placebo-acupuncture or waitlist-control when the recommended lowest threshold dosage (12 sessions) was met. Despite positive outcomes, most studies reviewed were heterogeneous and at risk of bias due to methodological issues. CONCLUSIONS: Despite limited evidence, acupuncture was significantly associated with improvements in several objective sleep parameters (increases in total sleep time and sleep efficiency, and reductions in wake after sleep onset and number of awakening times) as well as subjective sleep quantity and quality in patients with PI. A minimum therapeutic threshold dosage (≥12 sessions) is recommended. Well-designed RCTs using PSG are required to clarify the influence of acupuncture on sleep architecture/structure and to promote better application of acupuncture as a treatment for PI.

[Effect of Tongdu Tiaoshen needling in treatment of chronic insomnia by regulating the hypothalamic-pituitary-adrenal axis].

OBJECTIVE: To investigate the clinical effect of Tongdu Tiaoshen needling in the treatment of chronic insomnia and its mechanism based on the hypothalamic-pituitary-adrenal (HPA) axis. METHODS: A total of 60 patients with chronic insomnia were randomly divided into treatment group and control group, with 30 patients in each group. In addition to the health education on sleep, the patients in the treatment group were given Tongdu Tiaoshen needling, i．e., electroacupuncture at Baihui (GV20), Shenting (GV24), Yintang (EX-HN3), bilateral Shenmen (HT7), and bilateral Sanyinjiao (SP6), and those in the control group were given superficial acupuncture at Shousanli (LI10), Futu (ST32), and Feiyang (BL58) at both sides, once every other day and three times a week for 4 consecutive weeks. Before and after treatment, the Pittsburgh Sleep Quality Index (PSQI) was used to assess the quality and efficiency of sleep, and ELISA was used to measure the serum levels of corticotropin-releasing hormone (CRH), adrenocorticotropic hormone (ACTH), and corticosterone (CORT). RESULTS: After treatment, the treatment group had significant reductions in the total PSQI score and the score of each component of PSQI (P<0.01), and the control group had significant reductions in the total PSQI score (P<0.01) and the scores of all components except sleep duration (P<0.05); compared with the control group, the treatment group had significantly lower total PSQI score and the score of each component (P<0.01). After treatment, the treatment group had significant reductions in the serum levels of CRH, ACTH and CORT (P<0.05，P <0.01), and compared with the control group, the treatment group had significant reductions in the serum levels of CRH, ACTH and CORT (P<0.01，P<0.05). CONCLUSION: Tongdu Tiaoshen needling has a good clinical effect in the treatment of chronic insomnia and can significantly improve the sleep condition of patients with chronic insomnia, possibly by reducing the hormones associated with the HPA axis.

[Effect of thunder-fire moxibustion combined with vibration training on low back pain of primary osteoporosis].

OBJECTIVE: To compare the therapeutic effect of thunder-fire moxibustion combined with vibration training and simple vibration training on low back pain of primary osteoporosis by Young's modulus of ultrasonic wave, and seek an objective evaluating method. METHODS: A total of 60 patients were randomized into an observation group and a control group, 30 cases in each one. The patients in the two groups were treated with vibration training using whole body vibration treatment bed. In the observation group, thunder-fire moxibustion was applied at Yaoyangguan (GV 3), Mingmen (GV 4), Ganshu (BL 18), Shenshu (BL 23) and Dachangshu (BL 25). The treatment was given once every other day, 3 times a week for 4 weeks. The visual analogue score (VAS), real-time shear wave elastography (RTSWE) and medical outcomes study 36-item short-form hearth survey (SF-36) were used to evaluate pain intensity, multifidus muscle tone (Young's modulus) and quality of life before treatment, after 4-week treatment and 1 month after treatment. RESULTS: Compared before treatment, the VAS scores, Young's modulus of multifidus muscle and 5 dimensions of SF-36 (physical condition, body pain, general health, social function and mental health) after 4-week treatment and 1 month after treatment were significantly improved in the two groups (all P<0.05), the physiological role in the observation group after 4-week treatment and 1 month after treatment were improved (both P<0.05). In the observation group, the VAS scores, Young's modulus of multifidus muscle and 3 dimensions of SF-36 (physiological role, body pain and general health) after 4-week treatment and 1 month after treatment were superior to the control group (all P<0.05). CONCLUSION: The therapeutic effect of thunder-fire moxibustion combined with vibration training is superior to simple vibration training in relieving low back pain intensity and multifidus muscle tone, and improving quality of life for primary osteoporosis. RTSWE technique can be an objective examination method to evaluate pain.

[Insomnia treated with three acupuncture combinations guided by theory of Tongdu Tiaoshen: a randomized controlled trial].

OBJECTIVE: To compare the clinical therapeutic effect and safety on insomnia among three acupuncture combinations, named Tongdu Tiaowei (promoting the circulation of the governor vessel and regulating the defensive system), Tongdu Yangxin (promoting the circulation of the governor vessel and nourishing the heart) and Tongdu Tiaozang (promoting the circulation of the governor vessel and regulating zang functions). METHODS: A total of 90 patients with insomnia were randomized into a Tongdu Tiaowei group (30 cases, 1 case dropped off ), a Tongdu Yangxin group (30 cases, 2 cases dropped off ) and a Tongdu Tiaozang group (30 cases, 1 case dropped off ). Besides electroacupuncture (EA) applied to Baihui (GV 20) and Yintang (GV 29) in all of the three groups, acupuncture was added at Shenmai (BL 62) and Zhaohai (KI 6), Shenmen (HT 7) and Sanyinjiao (SP 6) as well as back-shu points of five zang organs [Feishu (BL 13), Xinshu (BL 15), Ganshu (BL 18), Pishu (BL 20) and Shenshu (BL 23)] in the Tongdu Tiaowei group, the Tongdu Yangxin group and the Tongdu Tiaozang group successively. The treatment was given once every two days, 3 times weekly, consecutively for 4 weeks. The score of Pittsburgh sleep quality index (PSQI) before and after treatment was observed, the therapeutic effect was evaluated and the adverse reactions were recorded in the patients of each group. RESULTS: After treatment, the score of each of 6 factors, named sleep quality, sleep latency, sleep time, sleep efficiency, sleep disturbance and daytime dysfunction, as well as the total score of PSQI scale were all reduced as compared with the scores before treatment in the patients of each group (P<0.05). After treatment, the scores of sleep latency and daytime dysfunction in the Tongdu Tiaowei group were lower than the other two groups (P<0.05). The score of sleep time in the Tongdu Yangxin group was lower than the other two groups (P<0.05) and the score of sleep quality in the Tongdu Tiaozang group was lower than the other two groups (P<0.05). After treatment, the total effective rates were 96.6% (28/29), 96.4% (27/28) and 96.6% (28/29) in the Tongdu Tiaowei group, the Tongdu Yangxin group and the Tongdu Tiaozang group successively, without significant difference in comparison among the three groups (P>0.05). During treatment, 1 case of mild adverse reaction occurred in each group. CONCLUSION: All of the three acupuncture combinations, named Tongdu Tiaowei, Tongdu Yangxin and Tongdu Tiaozang can effectively improve the sleep conditions in the patients with insomnia and are satisfactory in safety. The acupuncture combinations of Tongdu Tiaowei has the potential advantage in shortening sleep latency and relieving daytime dysfunction, the combinations of Tongdu Yangxin has the potential advantage in increasing sleep time and the combinations of Tongdu Tiaozang has the potential advantage in improving sleep quality.

[Inhibitory Effect of Acupoint Application on Airway Remodeling and Expression of TGF-ß 1/Smad 3 in the Lung Tissue of Chronic Asthma Mice].

OBJECTIVE: To observe the effect of acupoint application on transforming growth factor (TGF)-ß 1/Smad 3 signaling pathway, so as to reveal its mechanism underlying improvement of airway remodeling in chronic asthma mice. METHODS: BALB/c mice were randomly divided into normal group,model group,sham acupoint application group (sham group),acupoint application group, and dexamethasone group (n=8 in each group). The chronic asthma model was established by intraperitoneal injection of ovalbumin sensitization. The acupoint application group was treated with plaster composed with White Mustard Seed, Rhizoma Corydalis, Unprocessed Radix Kansui, and Herba Asari, on bilateral "Feishu" (BL 13), "Xinshu" (BL 15) and "Geshu" (BL 17) points, 6 hours a day for 14 days. The sham group was treated with plaster containing vaseline on bilateral BL 13, BL 15 and BL 17, 6 hours a day for 14 days. The dexamethasone group was treated with dexamethasone 1 mg·kg-1·day-1 intraperi-toneally, once daily for 14 days. At the end of treatment, airway resistance was detected by mouse lung function instrument. Patho-logical changes of airway were observed under light microscope after hematoxylin-eosin staining, and the morphological parameters were measured by image analysis software. Immunohistochemistry method was used to detect the expression of TGF-ß 1 and Smad 3 in the lung tissue of mice. RESULTS: Compared with the normal group, the airway resistance, the total bronchial wall area (WAt)/lumen perimeter (Pi), the smooth muscle wall area (WAm)/Pi, and the expression of TGF-ß 1 and Smad 3 in the lung tissues were significantly higher in the model and sham groups (P<0.01). Compared with the model group and the sham group, the airway resistance, WAt/Pi, WAm/Pi, the expression of TGF-ß 1 and Smad 3 in the lung tissues were decreased in the acupoint application group and the dexamethasone group (P<0.05). There were no significant differences between the acupoint application group and the dexamethasone group in the above mentioned indexes (P>0.05). CONCLUSIONS: Acupoint application can improve airway remodeling by down-regulating the expression of TGF-ß 1/Smad 3 in the airway of chronic asthmatic mice.

[Effect of Decitabine in Combination with Arsenic Trioxide on Prolife-ration and Apoptosis of Human Acute Myeloid Leukemia MV4-11 Cells].

OBJECTIVE: To investigate the effect of decitabine (DAC) alone or in combination with arsenic trioxide (As2O3) on the proliferation and apoptosis of human acute myeloid leukemia (AML) MV4-11 cells, so as to find an effective method for treating AML with MLL rearrangements. METHODS: The inhibitory effect of DAC and As2O3 alone, as well as in a combination of less than 50% inhibitory concentration (IC50) of DAC, and with less than 20% inhibitory concentration (IC20) As2O3 on MV4-11 cell proliferation were detected by CCK-8 methed; and the apoptosis inducing effect was determined by flow cytometry. RESULTS: The inhibitory effect of DAC or As2O3 alone on the cell proliferation increased along with the augment of drug concentration in a dose-dependent manner, both were statistically significant (P<0.01) in comparison the control group. The IC50 of DAC and As2O3 on MV4-11 cells were 2.409 µmol/L and 2.364 µmol/L, respectively. When compared with DAC alone in the same concentration gradient, the combined chemotherapy of DAC(0.01, 0.1, 0.5, 1 µmol/L) and As2O3(0.25 µmol/L) showed higher inhibitory effect on cell proliferation and there was statistically differences (P<0.05). The 48 h apoptotic rate of DAC (5.0 µmol/L) on MV4-11 was 13.50%±1.87%; and the 48 h apoptotic rate of As2O3 (2 µmol/L) was 12.60%±2.33%; while the 48 h apoptotic rate in combination of 2 drugs was 51.13%±4.97%. CONCLUSION: DAC or As2O3 can remarkably inhibit MV4-11 cell proliferation and induce apoptosis, and the combination of two drugs displays a synergistic effect.
