OBJECTIVES: To compare the efficacy of needle retaining after electroacupuncture combined with cognitive training and electroacupuncture combined with cognitive training in the treatment of post-stroke cognitive impairment (PSCI). METHODS: A total of 206 patients with PSCI were randomized into a needle retaining group (103 cases, 9 cases dropped out) and an electroacupuncture group (103 cases, 6 cases dropped out). In addition to the conventional basic medical treatment and the rehabilitation treatment, in the needle retaining group, electroacupuncture at Shenting (GV 24) and Baihui (GV 20) was applied, with continuous wave of 50 Hz in the first 15 min and with disperse-dense wave of 2 Hz/50 Hz in the last 15 min, the needles were continuously retained for 1 h after electroacupuncture, during which cognitive training was adopted; in the electroacupuncture group, cognitive training was performed after the same electric stimulation exerted for 30 min, without additional needles retaining. The treatment was given once a day, 5 times a week for totally 8 weeks in the two groups. Before and after 8-week treatment, the TCM syndrome score was observed; before and after 4,8-week treatment, the scores of mini-mental state examination (MMSE), Montreal cognitive assessment (MoCA) and ability of daily living were observed in the two groups. The clinical efficacy of the two groups was evaluated after 8-week treatment. RESULTS: After 8-week treatment, the TCM syndrome scores were increased compared with those before treatment in both groups (P<0.05); the TCM syndrome score in the needle retaining group was higher than that in the electroacupuncture group (P<0.05).After 4,8-week treatment, the scores of MMSE, MoCA and ability of daily living were increased compared with those before treatment in both groups (P<0.05); MMSE, MoCA scores after 4,8-week treatment and ability of daily living score after 8-week treatment in the needle retaining group were higher than those in the electroacupuncture group (P<0.05). The total effective rate was 90.4% (85/94) in the needle retaining group, which was superior to 82.5% (80/97) in the electroacupuncture group (P<0.05). CONCLUSIONS: Both needle retaining after electroacupuncture combined with cognitive training and electroacupuncture combined with cognitive training can effectively treat PSCI, improve the clinical symptom, cognitive function and ability of daily living in PSCI patients. Needle retaining after electroacupuncture combined with cognitive training has a better therapeutic effect.

[Effects of Governor Vessel electroacupuncture on chloridion homeostasis in the cortex of rats with limb spasm after cerebral ischemia-reperfusion].

OBJECTIVE: To observe the effect of electroacupuncture (EA) stimulation of Governor Vessel on chloridion (Cl-) homeostasis and the expression of γ-aminobutyric acid (GABA) and Na+-K+-Cl- cotransporter 1 (NKCC1) in the cerebral cortex of cerebral ischemia-reperfusion injury (CIRI) model rats, so as to explore its mechanism underl-ying alleviating limb spasm after stroke. METHODS: Forty-five male SD rats were randomly divided into normal, sham-operation, model, EA and baclofen groups, with 9 rats in each group. The CIRI model was established by occlusion of the middle cerebral artery and reperfusion. EA(100 Hz) was applied to "Dazhui" (GV14), "Jizhong"(GV6) and "Houhui" for 30 min. Rats of the baclofen group received gavage of baclofen solution (0.4 mg/kg, 1 mL/100 g), once daily for 7 consecutive days. Neurological deficit score was assessed according to Zea Longa's method. The muscular tone of quadriceps femoris of the limb was evaluated by modified Ashworth scale and electrophysiological recor-ding methods, separately. TTC staining was used to detect cerebral infarction volume, and the brain water content of rats in each group was determined by wet and dry weight method. The contents of Cl- and GABA in the cerebral cortex were detected by colorimetric method, and the expression levels of NKCC1 mRNA and protein in the cerebral cortex were detected by quantitative real-time PCR and Western blot, separately. RESULTS: No significant differences were found between the normal and sham-operation groups in all the indexes. Compared with the normal and sham-operation groups, the neurological deficit score, modified Ashworth muscle tone score, brain water content, cerebral infarct volu-me percent, Cl- content and expression levels of NKCC1 mRNA and protein were all evidently increased (P<0.01), and muscle tone of electrophyiological electromyogram (EMG) signal and GABA content were strikingly decreased (P<0.01) in the model group. Compared with the model group, both EA and baclofen groups had an obvious increase in EMG signal displayed muscle tone, and GABA content (P<0.05, P<0.01), and a marked decrease in the neurological deficit score, modified Ashworth score, brain water content, cerebral infarct percent, Cl- content and expression levels of NKCC1 mRNA and protein (P<0.05, P<0.01). CONCLUSION: EA stimulation of acupoints of the Governor Vessel can improve the degree of limb spasm and reduce the degree of cerebral edema and infarction in rats with stroke, which may be related to its functions in protecting Cl- homeostasis, up-regulating GABA concentration, and down-regulating the expression of NKCC1 protein and mRNA in the cerebral cortex.

[Effect of electroacupuncture of Governor Vessel on expression of GAD67 and GABA-T in cerebral cortex of rats with post-stroke limb spasticity].

OBJECTIVE: To observe the effect of electroacupuncture (EA) of Governor Vessel (GV) on the expressions of glutamate decarboxylase 67 (GAD67) and γ-aminobutyric acid transaminase (GABA-T) in the cerebral cortex of rats with post-stroke limb spasticity, so as to explore its mechanism underlying improvement of limb spasticity. METHODS: Twenty four male SD rats were randomly and equally divided into control, sham operation, model, and EA groups. The cerebral ischemia model was established by occlusion of the middle cerebral artery (MCAO). EA (100 Hz, 1-3 mA) was applied to "Dazhui"(GV14), "Jizhong"(GV6) and "Houhui"( anteromedial of transverse process of the sixth lumbar vertebra) for 30 min, once daily for 7 consecutive days. The neurologic deficit score (0-5 points) was evaluated according to Zea Longa's method, and the muscular tension severity (0-5 points) was assessed according to the modified Ashworth muscle tone rating scale, and the tension signals of the quadriceps ferroris of the affected limb were recorded using tonotransducer and BL-420F electrophysiological recorder. The expression levels of GAD67 and GABA-T proteins and mRNAs in the cerebral cortex were detected by immunohistochemistry, fluorescence quantitative real-time PCR and Western blot, separately. RESULTS: After modeling, the neurological deficit score, muscle tone score, and the expression levels of GABA-T mRNA and protein in cerebral cortex were significantly increased (P<0.01, P<0.05), tension signal value and the expression levels of GAD67 mRNA and protein in cerebral cortex were significantly decreased (P<0.01) in the model group relevant to the control and sham operation groups. Following the intervention, the neurological deficit score, muscle tone score, and expression levels of GABA-T mRNA and protein in cerebral cortex were significantly decreased (P<0.01), tension signal value and the expression levels of GAD67 mRNA and protein in cerebral cortex were significantly increased (P<0.01, P<0.05) in the EA group in contrast to the model group. CONCLUSION: EA stimulation of Governor Vessel can ameliorate the limb spasticity symptom in MCAO rats, which may be associated with its functions in increasing the expressions of GAD67 protein and mRNA and inhibiting the expressions of GABA-T protein and mRNA, thereby playing the inhibitory role of GABA.

[Clinical observation on wrist-ankle acupuncture for shoulder-hand syndrome phaseâ after stroke].

OBJECTIVE: To compare the clinical efficacy between wrist-ankle acupuncture and conventional acupuncture on shoulder-hand syndrome (SHS) phaseⅠafter stroke. METHODS: A total of 64 patients with SHS phaseⅠafter stroke were randomized into a wrist-ankle acupuncture group and a conventional acupuncture group, 32 cases in each group. On the basis treatment of internal medicine and conventional rehabilitation, wrist-ankle acupuncture was applied at upper 4 area, upper 5 area and upper 6 area on the affected side in the wrist-ankle acupuncture group, while acupuncture was applied at Jianyu (LI 15), Quchi (LI 11), Shousanli (LI 10), etc. on the affected side in the conventional acupuncture group. The treatment was given 30 min each time, once a day, 5 days a week for 3 weeks in both groups. Before and after treatment, the visual analogue scale (VAS) score, degree of hand swelling, shoulder-hand syndrome scale (SHSS) score, Fugl-Meyer assessment for upper extremity (FMA-UE) score and modified Barthel index (MBI) score were observed, and the clinical therapeutic effect was evaluated in both groups. RESULTS: After treatment, the VAS scores, degree of hand swelling and SHSS scores were decreased (P<0.05), and the FMA-UE scores and MBI scores were increased (P<0.05) compared before treatment in both groups; in the wrist-ankle acupuncture group, the VAS score, degree of hand swelling and SHSS score were lower (P<0.05), and the FMA-UE score and MBI score were higher (P<0.05) than those in the conventional acupuncture group. The total effective rate was 96.9% (31/32) in the wrist-ankle acupuncture group, which was superior to 90.6% (29/32) in the conventional acupuncture group (P<0.05). CONCLUSION: Wrist-ankle acupuncture can effectively relieve pain and hand swelling, improve motor function of upper extremity and self-care ability of daily life in patients with shoulder-hand syndrome phaseⅠafter stroke, the therapeutic effect is superior to conventional acupuncture.

The Clinical Observation and Mechanism of Acupuncture on Cancer-Related Fatigue of Breast Cancer Based on "Gut-Brain Axis": Study Protocol for a Randomized Controlled Trial.

Background. Cancer-related fatigue (CRF) is a painful, persistent feeling of physical and cognitive subjective fatigue related to cancer or cancer remedy. The occurrence of CRF may be related to the hypothalamic-pituitary-adrenaline (HPA) axis, inflammatory mediator theory, and gut microbiota. Moreover, acupuncture could play a vital part in the therapy of CRF. The study will evaluate whether acupuncture can improve fatigue symptoms of CRF patients after breast cancer chemotherapy by regulating the gut-brain axis. Methods/design. Seventy patients with CRF will be enrolled in this study, with 35 patients randomly assigned to each group. Blood and feces will be collected at the beginning and end of treatment. Piper fatigue scale, KPS score scale, and quality-of-life scale will be used to observe the changes of fatigue symptoms and life quality of CRF patients and to evaluate the effect of acupuncture on CRF. Then, the method of ELISA will be used to explore the regulatory effect of acupuncture on the HPA axis and inflammatory cytokines. Moreover, based on 16SrDNA, the changes of gut microbiota structure and flora of CRF patients will be observed. Ultimately, the correlation analysis of gut microbiota can be related to inflammatory cytokines, HPA axis, and clinical efficacy evaluation. Discussion. This study will identify the effect and the mechanism of acupuncture therapy in CRF. And it will offer an alternative treatment modality for the treatment of CRF after chemotherapy for breast cancer. Furthermore, it will also provide the clinical and theoretical bases for the extensive application of acupuncture therapy in tumor rehabilitation. Trial Status. Protocol version number and date: V2.0, 6 May 2021. The trial is registered with the Chinese Clinical Trial Registry on 20 June 2021 (trial identifier: ChiCTR2100047510).

[Acupoint selection rules of post-stroke cognitive impairment treated with acupuncture based on ancient and modern medical record cloud platform].

OBJECTIVE: To analyze the acupoint selection rules of post-stroke cognitive impairment (PSCI) treated with acupuncture by ancient and modern medical record cloud platform (V1.5). METHODS: The published randomized controlled trial (RCT) literature of PSCI treated with acupuncture was retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library and Web of Science, and the data was extracted to establish prescription database. The ancient and modern medical record cloud platform (V1.5) was used to analyze the data. RESULTS: A total of 185 articles was included, involving 91 acupoints, the total using frequency was 1174 times. The top 5 acupoints in frequency of PSCI treated with acupuncture were Baihui (GV 20, 151 times), Shenting (GV 24, 97 times), Sishencong (EX-HN 1, 83 times), Neiguan (PC 6, 69 times) and Sanyinjiao (SP 6, 64 times); the most involved meridian was the governor vessel, and the generally used acupoints were mainly distributed in the head, face and neck. The top 5 acupoint combinations in frequency were Baihui (GV 20)-Shenting (GV 24, 89 times), Baihui (GV 20)-Sishencong (EX-HN 1, 79 times), Baihui (GV 20)-Neiguan (PC 6, 59 times), Baihui (GV 20)-Sanyinjiao (SP 6, 56 times) and Baihui (GV 20)-Zusanli (ST 36, 51 times). The acupoint combination with the strongest association was Shenting (GV 24)→Baihui (GV 20). There were 6 acupoint cluster groups according to the cluster analysis, and the main core prescription was Baihui (GV 20), Shenting (GV 24), Sishencong (EX-HN 1), Zusanli (ST 36), Neiguan (PC 6) and Sanyinjiao (SP 6). CONCLUSION: Acupoints on the governor vessel, and distributed in head, face and neck are the main acupoints for PSCI treated with acupuncture, Baihui (GV 20), Shenting (GV 24), Sishencong (EX-HN 1), Zusanli (ST 36), Neiguan (PC 6) and Sanyinjiao (SP 6) can be used as the main acupoints, but it is still necessary to combine with syndrome differentiation.

Effects of different acupuncture treatment methods on post-stroke cognitive impairment: study protocol for a multicenter randomized controlled trial.

BACKGROUND: Cognitive impairment is a common dysfunction after stroke that seriously affects the overall recovery of patients. Cognitive rehabilitation training is currently the main treatment to improve cognitive function, but its curative effect is limited. Acupuncture is a core component of traditional Chinese medicine (TCM), and some previous clinical studies have shown that it might be effective in treating post-stroke cognitive impairment (PSCI), but further evidence from large-sample studies is needed. The overall objective of this trial is to obtain further data to develop an optimized acupuncture treatment for PSCI by comparing the effects of different acupuncture treatment methods on cognitive function in PSCI patients. METHODS/DESIGN: In this multicenter, prospective, randomized controlled trial, 206 eligible stroke inpatients who meet the trial criteria will be randomly assigned to 2 groups: an electroacupuncture (EA) plus needle retention (NR) group and an EA group. Both groups of patients will undergo the same routine cognitive rehabilitation treatments. All treatments will be given 5 times per week for 8 weeks. The primary outcomes will be assessed using the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment scale (MOCA). The secondary outcome will be measured by the Barthel Index (BI). All outcomes will be evaluated at baseline, week 4, week 8, and the third and sixth month after the end of treatment. DISCUSSION: Our aim is to evaluate the effects of two different acupuncture treatment methods for treating PSCI patients. This study is expected to provide data to be used in developing an optimized acupuncture treatment method for PSCI treatment. TRIAL REGISTRATION: Chinese Clinical Trial Registry ChiCTR1900027849.

Electroacupuncture improves learning and memory functions in a rat cerebral ischemia/reperfusion injury model through PI3K/Akt signaling pathway activation.

Electroacupuncture has been widely used to treat cognitive impairment after cerebral ischemia, but the underlying mechanism has not yet been fully elucidated. Studies have shown that autophagy plays an important role in the formation and development of cognitive impairment, and the phosphoinositide 3-kinase (PI3K)/Akt signaling pathway plays an important role in autophagy regulation. To investigate the role played by the PI3K/Akt signaling pathway in the electroacupuncture treatment of cerebral ischemia/reperfusion rat models, we first established a rat model of cerebral ischemia/reperfusion through the occlusion of the middle cerebral artery using the suture method. Starting at 2 hours after modeling, electroacupuncture was delivered at the Shenting (GV24) and Baihui (GV20) acupoints, with a dilatational wave (1-20 Hz frequency, 2 mA intensity, 6 V peak voltage), for 30 minutes/day over 8 consecutive days. Our results showed that electroacupuncture reduced the infarct volume in a rat model of cerebral ischemia/reperfusion injury, increased the mRNA expression levels of the PI3K/Akt signaling pathway-related factors Beclin-1, mammalian target of rapamycin (mTOR), and PI3K, increased the protein expression levels of phosphorylated Akt, Beclin-1, PI3K, and mTOR in the ischemic cerebral cortex, and simultaneously reduced p53 mRNA and protein expression levels. In the Morris water maze test, the latency to find the hidden platform was significantly shortened among rats subjected to electroacupuncture stimulation compared with rats without electroacupuncture stimulation. In the spatial probe test, the number of times that a rat crossed the target quadrant was increased in rats subjected to electroacupuncture stimulation compared with rats without electroacupuncture stimulation. Electroacupuncture stimulation applied to the Shenting (GV24) and Baihui (GV20) acupoints activated the PI3K/Akt signaling pathway and improved rat learning and memory impairment. This study was approved by the Animal Ethics Committee of the First Affiliated Hospital of Henan University of Traditional Chinese Medicine, China (approval No. 8150150901) on March 10, 2016.

The comparative effectiveness of traditional Chinese medicine exercise therapies in elderly people with mild cognitive impairment: A protocol for a network meta-analysis.

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