ABSTRACT

ABSTRACT Introduction: Meniscal injury is a common condition that can lead to disability due to pain and proprioceptive failure, requiring immediate attention. Combination therapies involve advanced approaches aiming to accelerate rehabilitation in athletes, and electroacupuncture presents therapeutic benefits, although there is still no evidence of its combination with sports therapy. Objective: This paper analyzes the performance of sports rehabilitation in athletes with meniscal lesions using electroacupuncture combined with sports therapy. Methods: The intervention in the control group was based on a traditional range of motion work, muscle strength, proprioceptive training, and other exercise therapies, while the experimental group received a 30 min electro-acupuncture protocol three times a week for four consecutive weeks. The surrogate data (gender, age, disease course, location) are the same. Before treatment, joint activity, muscle strength, total joint scale score of the LYSHOLM questionnaire, and other observational indices were measured during the 6th and 12th week of treatment. The non-parametric statistical method and T-test were used to analyze the changes of each index before and after treatment. After 12 weeks of treatment, the difference between the experimental group and the combination before treatment was significant. Results: The treatment effect of the experimental group was significantly better than the control group. Conclusion: The effect of sports rehabilitation of athletes with meniscus injury based on electroacupuncture combined with sports therapy showed high resolutive application value, indicating an alternative for non-surgical treatment in knee meniscus injuries. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

ABSTRACT

RESUMEN Introducción: Los trastornos temporomandibulares constituyen una condición dolorosa que afecta los músculos de la masticación, la articulación temporomandibular, así como varias estructuras anatómicas del sistema estomatognático. Objetivo: Evaluar la efectividad de la electroacupuntura en pacientes con síndrome de dolor miofacial asociado a disfunción de la articulación temporomandibular. Métodos: Se realizó un estudio cuasiexperimental de intervención terapéutica en 80 pacientes asistidos en el Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, desde noviembre del 2018 hasta igual mes de 2021, quienes padecían dolor miofacial por disfunción en las articulaciones temporomandibulares. Estos fueron asignados de forma alterna en dos grupos terapéuticos de 40 integrantes cada uno: el de estudio, al que se le aplicó electroacupuntura, y el de control, el cual recibió medicación farmacológica convencional; luego, se les fue evaluando clínicamente al tercero, quinto, séptimo y décimo días de iniciadas las terapias. Las variables fueron procesadas estadísticamente aplicando el porcentaje como medida de resumen y la prueba de la Χ2 para estimar diferencias en cuanto al tiempo promedio de buena evolución, con un nivel de significación de 0,05. Resultados: Antes de comenzar los tratamientos, el dolor era intenso en la mayoría de los pacientes de ambos grupos; sin embargo, al tercer día de iniciada la intervención terapéutica, la evolución había sido buena en 45,0 % del grupo de estudio y 32,5 % del grupo de control; al quinto día este porcentaje había aumentado a 60,0 en los que recibieron electroacupuntura, pero se mantuvo igual en los que fueron tratados convencionalmente. Al finalizar la intervención se había logrado la recesión o el alivio del dolor miofacial en 97,5 % de los casos y en 90,0 % de los controles. Conclusiones: La electroacupuntura resultó clínicamente más efectiva para paliar el dolor miofacial producido por los trastornos temporomandibulares, con un menor tiempo promedio de buena respuesta terapéutica.


ABSTRACT Introduction: The temporomandibular disorders constitute a painful condition that affects the mastication muscles, the temporomandibular joint, as well as several anatomical structures of the stomatognathic system. Objective: To evaluate the effectiveness of electroacupuncture in patients with syndrome of miofacial pain associated with temporomandibular joint dysfunction. Methods: A quasi-experiment study of therapeutic intervention in 80 patients assisted in Dr. Juan Bruno Zayas Alfonso Teaching General Hospital from Santiago de Cuba, was carried out from November, 2018 to the same month in 2021, who suffered from miofacial pain due to dysfunction in the temporomandibular joint. These were assigned in an alternating way in two therapeutic groups of 40 members each one: that of study, to which electroacupuncture was applied, and that of control, which received conventional pharmacological medication; then, they were clinically evaluated at the third, fifth, seventh and tenth days after the therapy. The variables were statistically processed applying the percentage as summary measure and the chi-square test to estimate differences as for the average time of good evolution, with a level of significance of 0.05. Results: Before beginning the therapy, the pain was intense in most of the patients of both groups; however, at the third day of the therapies, the evolution had been good in 45.0 % of the study group and 32.5 % of the control group, and the fifth day this percentage had increased at 60.0 in those that received electroacupuncture, but stayed equally in those that were treated conventionally. When concluding the intervention recession or relief of the miofacial pain in 97.5 % of the cases and in 90.0 % of the controls was achieved. Conclusions: The electroacupuncture was clinically more effective than the conventional medication to palliate the miofacial pain caused by the temporomandibular disorders, with a less average time of good therapeutic response.

ABSTRACT

OBJECTIVE@#To investigate whether electroacupuncture (EA) alleviates cognitive impairment by suppressing the toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88) signaling pathway, which triggers immune-inflammatory responses in the hippocampus of rats with vascular dementia (VaD).@*METHODS@#The experiments were conducted in 3 parts and in total the Sprague-Dawley rats were randomly divided into 8 groups by a random number table, including sham, four-vessel occlusion (4-VO), 4-VO+EA, 4-VO+non-EA, sham+EA, 4-VO+lipopolysaccharide (LPS), 4-VO+LPS+EA, and 4-VO+TAK-242 groups. The VaD model was established by the 4-VO method. Seven days later, rats were treated with EA at 5 acupoints of Baihui (DV 20), Danzhong (RN 17), Geshu (BL 17), Qihai (RN 6) and Sanyinjiao (SP 6), once per day for 3 consecutive weeks. Lymphocyte subsets, lymphocyte transformation rates, and inflammatory cytokines interleukin-6 (IL-6) and tumor necrosis factor α(TNF-α) were measured to assess immune function and inflammation in VaD rats. Transmission electron microscopy was used to observe the ultrastructure of nerve cells in the hippocampus. The levels of TLR4, MyD88, IL-6, and TNF-α were detected after EA treatment. TLR4/MyD88 signaling and cognitive function were also assessed after intracerebroventricular injection of TLR4 antagonist TAK-242 or TLR4 agonist LPS with or without EA.@*RESULTS@#Compared with the 4-VO group, EA notably improved immune function of rats in the 4-VO+EA group, inhibited the protein and mRNA expressions of TLR4 and MyD88 in the hippocampus of rats, reduced the expressions of serum IL-6 and TNF-α (all P0.05).@*CONCLUSIONS@#EA attenuated cognitive impairment associated with immune inflammation by inhibition of the TLR4/MyD88 signaling pathway. Thus, EA may be a promising alternative therapy for the treatment of VaD.

ABSTRACT

OBJECTIVE@#To investigate the effect of electro-acupuncture (EA) on vasomotor symptoms in rats with acute cerebral infarction, by observing the changes in the expression of factors related to the phosphatidylinositol (PI) system.@*METHODS@#Forty-two Wistar rats were randomly divided into 3 groups by a random number table: the control group (n=6), the model group (n=18) and the EA group (n=18). The EA group was given EA treatment at Shuigou (GV 26) instantly after modeling with middle cerebral artery occlusion (MCAO) method, while the model and control groups were not given any treatment. The degrees of neurological deficiency were evaluated using neurological severity scores (NSS) and the brain blood flow was evaluated by a laser scanning confocal microscope. Western blot analysis was conducted to detect the expression levels of G-protein subtype (Gq) and calmodulin (CaM). Competition for protein binding was conducted to detect the expression level of inositol triphosphate (IP3). Thin layer quantitative analysis was conducted to detect the expression level of diacylglycerol (DAG). The expression level of intracellular concentration of free calcium ion ([Ca@*RESULTS@#The NSS of the model group was significantly higher than the control group at 3 and 6 h after MCAO (P<0.01), while the EA group was significantly lower than the model group at 6 h (P<0.01). The cerebral blood flow in the model group was significantly lower than the control group at 1, 3 and 6 h after MCAO (P<0.01), while for the EA group it was remarkably higher than the model group at the same time points (P<0.01). The expressions of Gq, CaM, IP3, DAG and [Ca@*CONCLUSION@#EA treatment at GV 26 can effectively decrease the over-expression of related factors of PI system in rats with acute cerebral infarction, improve cerebral autonomy movement, and alleviate cerebral vascular spasm.

ABSTRACT

OBJECTIVES@#Electroacupuncture can enhance autophagic flow, promote neuronal regeneration, axonal and myelin remodeling to achieve the protection of spinal cord injury, but its role in neurogenic urine retention is not completely clear. This study aims to investigate whether the mechanism of electroacupuncture in the treatment of neurogenic urine retention is through autophagy mediated by adenosine monophosphate activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) pathway.@*METHODS@#A rat model of neurogenic urine retention after sacral spinal cord injury was established. The rats with successful model were randomly divided into a model group, an electroacupuncture group (electro-acupuncture for Ciliao, Zhongji, and Sanyinjiao by electronic stimulation, once a day, 20 min each time for 7 days), and an electroacupuncture+AMP-activated protein kinase (AMPK) inhibitor group (on the basis of the treatment of electroacupuncture group, 100 μg of AMPK inhibitor compound C was injected intramuscularly around the L2-3 intervertebral space on the 1st and 4th day). The normal group did not receive any treatment. The maximum bladder volume, bladder basal pressure, leak point pressure, and bladder compliance were recorded by multi-channel physiological recorder; the morphology of bladder tissue was observed by HE staining; autophagy was observed under transmission electron microscope; the expressions of LC3II and Beclin1 protein were observed by immunofluorescence staining; the protein levels of AMPK, phosphorylated-AMPK (p-AMPK), mTOR, phosphorylated-mTOR (p-mTOR), microtubule associated protein 1 light chain 3 (LC3) II and Beclin1 in bladder tissue were detected by Western blotting.@*RESULTS@#Compared with the normal group, the maximum bladder capacity, leak point pressure, bladder compliance, p-AMPK, LC3II, Beclin1 protein expressions in the bladder tissue of the model group increased, and the p-mTOR protein expressions were decreased (all P<0.05); compared with the model group, the maximum bladder capacity, bladder compliance, p-mTOR protein expression in the bladder tissue of the electroacupuncture group were decreased, and the p-AMPK, LC3II, and Beclin1 protein expressions were increased (all P<0.05); compared with the electroacupuncture group, the maximum bladder capacity, bladder compliance, p-mTOR protein expression in the bladder tissue of the electroacupuncture+AMPK inhibitor group were increased, the p-AMPK, LC3II, and Beclin1 protein expressions were decreased (all P<0.05). In the model group, the bladder became larger, with unclear and varying degrees of degeneration, severe tissue damage and autophagosome appeared; the bladder of the electroacupuncture group was smaller than that of the model group, and all levels were clearly visible with autophagy bodies; the layers were slightly disordered and damaged in the electroacupuncture + AMPK inhibitor group.@*CONCLUSIONS@#Electroacupuncture can activate autophagy through AMPK/mTOR pathway, thereby reducing neurogenic urine retention caused by spinal cord injury.

ABSTRACT

OBJECTIVE@#To investigate whether the antihypertensive mechanism of electroacupuncture (EA) is associated with attenuating phenotype transformation of vascular smooth muscle cells (VSMCs) via phosphoinositide3-kinase (PI3K)/protein kinase B (Akt) and mitogen-activated protein kinase (MAPK) signaling pathways.@*METHODS@#Eight Wistar-ktoyo (WKY) rats were set as normal blood pressure group (normal group). A total of 32 spontaneous hypertensive rats (SHRs) were randomly divided into 4 groups using random number tables: a model group, an EA group, an EA+PI3K antagonist group (EA+P group), and an EA+p38 MAPK agonist+extracellular signal-regulated kinase (ERK) agonist group (EA+M group) (n=8/group). SHRs in EA group, EA+P group and EA+M group received EA treatment 5 sessions per week for continuous 4 weeks, while rats in the normal and model groups were bundled in same condition. The systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) of each rat was measured at 0 week and the 4th week. After 4-week intervention, thoracic aorta was collected for hematoxylin-eosin (HE) staining, immunohistochemistry [the contractile markers α-smooth muscle actin (α-SMA) and calponin and the synthetic marker osteopontin (OPN)] and Western blot [α-SMA, calponin, OPN, PI3K, phosphorylated-Akt (p-Akt), Akt, p-p42/44 ERK, total p42/44 ERK, p-p38 MAPK and total p38 MAPK].@*RESULTS@#EA significantly reduced SBP, DBP and MAP (P<0.01). HE staining showed that the wall thickness of thoracic aorta in EA group was significantly decreased (P<0.01). From results of immunohistochemistry and Western blot, EA increased the expression of α-SMA and calponin, and decreased the expression of OPN (P<0.01). In addition, the expression of PI3K and p-Akt increased (P<0.01), while the expression of p-p42/44 ERK and p-p38 MAPK decreased in EA group (P<0.01). However, these effects were reversed by PI3K antagonist, p38 MAPK agonist and ERK agonist.@*CONCLUSIONS@#EA was an effective treatment for BP management. The antihypertensive effect of EA may be related with inhibition of phenotypic transformation of VSMCs, in which the activation of PI3K/Akt and the repression of MAPK pathway were involved.

ABSTRACT

Objective: To observe the effect of electroacupuncture (EA) of "concurrent treatment of the brain and heart" on angiogenesis and cortical vascular endothelial growth factor (VEGF) and brain-derived neurotrophic factor (BDNF) in rats with focal cerebral ischemia, and to explore the mechanism of EA in cerebral ischemia treatment. Methods: A total of 108 Sprague-Dawley rats, 27 rats were randomly selected as the sham-operation group, and the rest rats received the right middle cerebral artery occlusion operation for model preparation firstly, and then were divided into a model group, a traditional acupoint group, and a concurrent treatment of the brain and heart group, with 27 rats in each group. In the sham-operation group, only the carotid artery was isolated. EA at Shuigou (CV26), Quchi (LI11), Hegu (LI4), and Zusanli (ST36) in the traditional acupoint group, and EA at Fengfu (GV16), Baihui (GV20), Xinshu (BL15), and Neiguan (PC6) in the concurrent treatment of the brain and heart group were performed 4 h after the operation, once a day, for 14 consecutive days. Rats in the sham-operation group and the model group were identically fixed without any treatment. Before and after treatment, the modified neurological severity score (mNSS), regional cerebral blood flow (rCBF), and CD34 positive expression by immunohistochemistry were measured. The positive protein expression levels of VEGF and BDNF were detected by immunofluorescence, and the mRNA expression levels of VEGF and BDNF were detected by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Results: Compared with the sham-operation group, the mNSS, rCBF, and ischemic side cortical micro-vessel density (MVD) decreased, and the protein and mRNA expression levels of VEGF and BDNF increased in the model group (P<0.01). Compared with the model group, the mNSS of the two EA groups decreased, and the mNSS of the concurrent treatment of the brain and heart group was lower than that of the traditional acupoint group on the 14th day (P<0.05). Compared with the model group, the rCBF in the two EA groups increased, and the rCBF reached the highest on the 14th day (P<0.05 or P<0.01), and the rCBF in the concurrent treatment of the brain and heart group was higher than that in the traditional acupoint group (P<0.05); the MVD of the two EA groups was higher than that of the model group, and the MVD of the concurrent treatment of the brain and heart group was higher than that of the traditional acupoint group on the 7th and 14th days (P<0.05 or P<0.01). Compared with the model group, the protein and mRNA expression levels of VEGF and BDNF in the two EA groups increased (P<0.01). The VEGF expression level was the highest on the 7th day in the concurrent treatment of the brain and heart group (P<0.05), and the BDNF expression level was higher on the 7th and 14th days than on the 3rd day (P<0.05). The mRNA expression levels of VEGF and BDNF in both EA groups reached the highest on the 7th day (P<0.05 or P<0.01). Conclusion: EA therapy can up-regulate the VEGF and BDNF expression levels and increase the rCBF in the cortex of rats with focal cerebral ischemia, which may be one mechanism of EA in the cerebral ischemia treatment. The therapeutic effect is accumulated with the effective time, and the concurrent treatment of the brain and heart group is superior to the traditional acupoint group in promoting angiogenesis.

ABSTRACT

Objective: To observe the effects of electroacupuncture (EA) pretreatment on M1 polarization of alveolar macrophages (AMs) in rats with acute lung injury (ALI) induced by lipopolysaccharide (LPS), and to explore the potential protective mechanism of EA.Methods: Forty Sprague-Dawley rats were randomly divided into a normal group, a model group, and three groups of EA pretreatment [including a Chize (LU5) group, a Zusanli (ST36) group and a Chize (LU5) plus Zusanli (ST36) group], with eight rats in each group. The model rats of ALI were established by instilling LPS [2 mg/(kg·bw)] into the trachea of rats for 3 h. The rats in each EA pretreatment group were pretreated with EA for 30 min per day at the corresponding bilateral acupoints 6 d before instilling LPS. Three hours after modeling, the pulmonary function of the rats was tested, and the lung tissue was taken to calculate the ratio of lung wet weight to dry weight (W/D). The pathological lung changes and the injury score were observed by hematoxylin-eosin staining. The contents of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and myeloperoxidase (MPO) in rat's bronchoalveolar lavage fluid (BALF) were detected by enzyme-linked immunosorbent assay. The mRNA and protein expression levels of M1 macrophage markers clusters of differentiation 86 (CD86), inducible nitric oxide synthase (iNOS), and its signaling pathway factor Toll-like receptor (TLR) 4, and nuclear factor-κB (NF-κB) p65 in the alveoli were detected by fluorescence quantitative polymerase chain reaction and Western blot, respectively. Results: After being induced by LPS, the pulmonary function of the model rats showed that the forced expiratory volume in 0.1 s (FEV0.1), forced expiratory volume in 0.3 s (FEV0.3), and their respective ratios of FEV to forced vital capacity (FVC) (including FEV0.1/FVC and FEV0.3/FVC) were significantly decreased (P<0.01), while the W/D of lung tissue was increased (P<0.01). The score of lung injury was significantly higher (P<0.01). The contents of TNF-α, IL-1β, and MPO in the BALF and the mRNA and protein expression levels of CD86, iNOS, TLR4, and NF-κB p65 in the lung tissue were significantly increased (P<0.01). After EA pretreatment, the FEV0.1, FEV0.3, FEV0.1/FVC, and FEV0.3/FVC were significantly increased, the lung injury score decreased significantly, and the contents of TNF-α, IL-1β, and MPO in the BALF and the expression levels of CD86, iNOS, TLR4, and NF-κB p65 mRNAs and proteins in the alveoli decreased significantly (P<0.05 or P<0.01). Compared with the other two single acupoint groups, the contents of TNF-α, IL-1β, and MPO in the BALF and the expression levels of CD86, iNOS, TLR4, and NF-κB p65 mRNAs in the alveoli in the Chize (LU5) plus Zusanli (ST36) group were significantly lower (P<0.01). Conclusion: EA pretreatment at Chize (LU5) and Zusanli (ST36) can inhibit inflammation and reduce pulmonary injury in ALI rats induced by LPS. The effect of the combination of Chize (LU5) and Zusanli (ST36) is better than that of using these two acupoints separately, and its mechanism may be related to the inhibition of AMs' M1 polarization by down-regulation TLR4/NF-κB signaling pathway.

ABSTRACT

Objective: To observe the effects of electroacupuncture (EA) with three frequencies (100 Hz, 2 Hz, and 2 Hz/100 Hz) on the apoptosis of neurons and c-Jun N-terminal kinase (JNK) signaling pathway in the hippocampus of rats with vascular dementia (VD), and explore the mechanism of EA intervention for VD. Methods: Fifty male Sprague-Dawley rats were randomly divided into a model group, a sham operation group, a 100 Hz EA group, a 2 Hz EA group, and a 2 Hz/100 Hz EA group, with ten rats in each group. The VD model rats were established by repeated ischemia-reperfusion of bilateral common carotid arteries. The rats in the EA groups received EA intervention at Baihui (GV20), Dazhui (GV14), Geshu (BL17) and Zusanli (ST36), once a day for 14 d. Afterward, Morris water maze was used to examine the learning and memory performances of the rats in each group, hematoxylin-eosin staining to observe the histomorphological changes in the hippocampal CA1 region, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling to test the apoptosis of neurons in the hippocampal CA1 region, and Western blot to detect the protein expression levels of JNK, phosphorylated JNK (p-JNK), Caspase-8, and Caspase-3 in the hippocampus tissue. Results: Compared with the sham operation group, the escape latency of the model group in water maze test was prolonged; the number of crossing the original platform was decreased (P<0.01); the hippocampal neurons were severely damaged and the number of surviving neurons was decreased (P<0.01), whereas the number of apoptotic neurons was increased (P<0.01); the protein expression levels of JNK, p-JNK, Caspase-8, and Caspase-3 in the hippocampus were significantly increased (P<0.01). Compared with the model group, the escape latency of each EA group was significantly shortened; the number of crossing the original platform was significantly increased (P<0.01); the damage of hippocampal neurons was alleviated, the number of surviving neurons was increased (P<0.01), and the number of apoptotic neurons was decreased (P<0.01); the protein expression levels of JNK, p-JNK, Caspase-8, and Caspase-3 in the hippocampus were decreased (P<0.01). The results in the 2 Hz EA group and the 2 Hz/100 Hz EA group were superior to those in the 100 Hz EA group. Conclusion: EA with the three frequencies (100 Hz, 2 Hz, and 2 Hz/100 Hz) can improve the learning and memory performances in VD rats subjected to ischemia-reperfusion, its mechanism may be related to the inhibition of neuronal apoptosis and the regulation of the related protein expression of JNK signaling pathway, and the intervention effects of EA with 2 Hz and 2 Hz/100 Hz are more significant.

ABSTRACT

Objective:To observe any effects of electroacupuncture (EA) on urodynamics and bladder c-Kit expression in rats with urination disorders after spinal cord injury (SCI).Methods:Complete spinal cord injury models were created in female Sprague-Dawley rats by transecting the spine at the thoracic or sacral level. On day 22 after the injury, the rats with successful modeling were randomized into a thoracic spinal cord injury (TSCI) group, a TSCI+ EA group, a sacral spinal cord injury (SSCI) group and an SSCI+ EA group, each of 10. Both EA groups were given 15 minutes of EA at the Guanyuan (CV4) and Sanyinjiao (SP6) points daily for 14 days. After the intervention, urination function was evaluated using bladder volume, compliance and residual urine volume. Hematoxylin and eosin staining was used to observe any morphological changes in bladder tissues. The gene and protein expression of c-Kit in bladder tissues were detected using real-time quantitative polymerase chain reactions and western blotting.Results:Compared with the sham group, the bladder volume and compliance of the TSCI group decreased significantly, while the average residual urine volume increased significantly. In the SSCI group the average residual urine volume, bladder volume and compliance all increased significantly. The modeling altered the morphology of the bladder in all of the SCI rats. The average expression of c-Kit mRNA and protein increased significantly in TSCI group, but both decreased significantly in the SSCI group. EA improved the histological structure of the SCI rats′ bladders.Conclusions:EA can bi-directionally regulate bladder c-Kit expression, and that is a possible mechanism for improving urinary incontinence and urine retention after an SCI.

ABSTRACT

Cognitive impairment seriously affects the quality of life of patients. Clinically, it is common in cerebral ischemia, sepsis and postoperative. Its etiology includes abnormal expression of regulatory molecules in the brain, ischemic injury of brain tissue and abnormal expression of genes and proteins in brain tissues. However, there is no effective treatment at present. Electroacupuncture has a certain effect on cognitive impairment. Its mechanism mainly includes inhibiting oxidative stress response, enhancing synaptic plasticity, inhibiting neuroinflammation, regulating glial cell activity, regulating excitatory amino acids, and improving glucose metabolism.

Postoperative pain was evaluated by VAS scale, pain duration, analgesic onset time, analgesic drug usage, wound healing time, nausea, vomiting and vertigo at 3 days after surgery were observed and recorded.Results:The VAS scores in the observation group were significantly lower than those in the control group at 12 hour and 1, 2,3 d postoperatively ( t=13.18, 13.71, 23.53 and 26.10, P<0.001). The duration of pain and the onset time of analgesia in the observation group were significantly shorter than those in the control group ( t=4.79, 7.54, 5.66, 15.60, P<0.001). The dosage of analgesic drugs in the observation group was significantly less than that in the control group at 48 and 72 h after operation ( t value 2.37 and 4.50, P<0.05 or P<0.01, respectively). The postoperative wound healing time [(26.58 ± 1.47) d vs. (35.75 ± 1.46) d, t=27.99] in the observation group was significantly earlier than that in the control group ( P<0.01), postoperative analgesic time [(7.10 ± 0.55) d vs. (11.32 ± 1.62) d, t=15.60] in the observation group were significantly earlier than those in the control group ( P<0.01). Conclusion:Electroacupuncture Baliao points can quickly reduce the postoperative pain, reduce the use of analgesic drugs, and speed up the postoperative recovery of patients with mixed hemorrhoids.

ABSTRACT

OBJECTIVE@#Emerging evidence shows the effectiveness of speech and language therapy (SLT); however, precise therapeutic parameters remain unclear. Evidence for the use of adjunctive transcranial direct current stimulation (tDCS) to treat post-stroke aphasia (PSA) is promising; however, the utility of combining tDCS and electroacupuncture (EA) has not yet been analyzed. This study assessed the therapeutic consequences of EA and tDCS coupled with SLT in subacute PSA patients who were also undergoing hyperbaric oxygen therapy (HBOT).@*METHODS@#A retrospective analysis was conducted on subacute (< 6 months) PSA patients who were divided into three groups: patients who received EA plus tDCS (acupuncture group), patients who underwent tDCS (tDCS group), and patients who experienced conventional therapy (HBOT + SLT). All subjects underwent 21 days of treatment and also received conventional treatment. The aphasia battery of Chinese (ABC) was used to score pre- and post-intervention status.@*RESULTS@#The analysis comprised 238 patients. Cerebral infarction was the most frequent stroke type (137 [57.6%]), while motor (66 [27.7%]) and global aphasia (60 [25.2%]) were the most common types of aphasia. After 21 days of intervention, the ABC scores of all patients were improved. The acupuncture group had the highest ABC scores, but only repetition, naming, and spontaneous speech were statistically improved (P < 0.01). Post-hoc tests revealed significant improvement in word retrieval in the acupuncture and tDCS groups (P < 0.01, P = 0.037), while the acupuncture group had additional significant improvement in spontaneous conversation (P < 0.01).@*CONCLUSION@#Combining acupuncture and tDCS as an adjuvant therapy for subacute PSA led to significant spontaneous speech and word retrieval improvements. Future prospective, multi-ethnic, multi-center trials are warranted.

ABSTRACT

OBJECTIVE@#To investigate the changes in the functional connectivity (FC) in the right insula between migraine without aura (MWoA) and healthy controls by using resting-state functional magnetic resonance imaging (rs-fMRI), and to observe the instant alteration of FC in MWoA during electroacupuncture (EA) stimulation at Shuaigu (GB8).@*METHODS@#A total of 30 patients with MWoA (PM group) and 30 healthy controls (HC group) underwent rs-fMRI scans. The PM group underwent a second rs-fMRI scan while receiving EA at GB8. The right insula subregions, including the ventral anterior insula (vAI), dorsal anterior insula (dAI) and posterior insula (PI), were selected as the seed points for FC analysis.@*RESULTS@#Aberrant FC, including dAI with right postcentral gyrus, PI with left precuneus, was found among PM before EA (PMa), PM during EA (PMb) and HC. Meanwhile, decreased FC between dAI and the right postcentral gyrus was found in the PMa compared to the HC and PMb. Increased FC between the PI and left precuneus was found in the PMa compared to the HC and PMb. Correlation analysis showed that the FC value of the right postcentral gyrus in PMa was negatively correlated with the scores of Hamilton Rating Scale for Depression and Hamilton Rating Scale for Anxiety. The FC value of the left precuneus in PMa was positively correlated with the visual analogue scale score.@*CONCLUSION@#The alteration of FC between the right insula subregions and multiple brain regions may be an important index for MWoA. EA at GB8 was able to adjust the FC between the right insula subregions and parietal lobe, namely, the right dAI and right postcentral gyrus, and the right PI and left precuneus, thereby rendering an instant effect in the management of MWoA.

ABSTRACT

OBJECTIVE@#To investigate the influence of electroacupuncture (EA) on ghrelin and the phosphoinositide 3-kinase/protein kinase B/endothelial nitric oxide synthase (PI3K/Akt/eNOS) signaling pathway in spontaneously hypertensive rats (SHRs).@*METHODS@#Eight Wistar-Kyoto rats were used as the healthy blood pressure (BP) control (normal group), and 32 SHRs were randomized into model group, EA group, EA plus ghrelin group (EA + G group), and EA plus PF04628935 group (a potent ghrelin receptor blocker; EA + P group) using a random number table. Rats in the normal group and model group did not receive treatment, but were immobilized for 20 min per day, 5 times a week, for 4 continuous weeks. SHRs in the EA group, EA + G group and EA + P group were immobilized and given EA treatment in 20 min sessions, 5 times per week, for 4 weeks. Additionally, 1 h before EA, SHRs in the EA + G group and EA + P group were intraperitoneally injected with ghrelin or PF04628935, respectively, for 4 weeks. The tail-cuff method was used to measure BP. After the 4-week intervention, the rats were sacrificed by cervical dislocation, and pathological morphology of the abdominal aorta was observed using hematoxylin-eosin (HE) staining. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of ghrelin, nitric oxide (NO), endothelin-1 (ET-1) and thromboxane A2 (TXA2) in the serum. Isolated thoracic aortic ring experiment was performed to evaluate vasorelaxation. Western blot was used to measure the expression of PI3K, Akt, phosphorylated Akt (p-Akt) and eNOS proteins in the abdominal aorta. Further, quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to measure the relative levels of mRNA expression for PI3K, Akt and eNOS in the abdominal aorta.@*RESULTS@#EA significantly reduced the systolic BP (SBP) and diastolic BP (DBP) (P < 0.05). HE staining showed that EA improved the morphology of the vascular endothelium to some extent. Results of ELISA indicated that higher concentrations of ghrelin and NO, and lower concentrations of ET-1 and TXA2 were presented in the EA group (P < 0.05). The isolated thoracic aortic ring experiment demonstrated that the vasodilation capacity of the thoracic aorta increased in the EA group. Results of Western blot and qRT-PCR showed that EA increased the abundance of PI3K, p-Akt/Akt and eNOS proteins, as well as expression levels of PI3K, Akt and eNOS mRNAs (P < 0.05). In the EA + G group, SBP and DBP decreased (P < 0.05), ghrelin concentrations increased (P < 0.05), and the concentrations of ET-1 and TXA2 decreased (P < 0.05), relative to the EA group. In addition, the levels of PI3K and eNOS proteins, the p-Akt/Akt ratio, and the expression of PI3K, Akt and eNOS mRNAs increased significantly in the EA + G group (P < 0.05), while PF04628935 reversed these effects.@*CONCLUSION@#EA effectively reduced BP and protected the vascular endothelium, and these effects may be linked to promoting the release of ghrelin and activation of the PI3K/Akt/eNOS signaling pathway.

ABSTRACT

OBJECTIVE@#To study the effect of electroacupuncture (EA) on oxaliplatin-induced peripheral neuropathy (OIPN) in rats.@*METHODS@#Male Sprague-Dawley rats were equally divided into 3 groups using a random number table: the control group, the OIPN group, and the EA (OIPN + EA) group, with 10 rats in each. The time courses of mechanical, cold sensitivity, and microcirculation blood flow intensity were determined. The morphology of the dorsal root ganglion (DRG) was observed by electron microscopic examination. The protein levels of nuclear factor E2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), and the transient receptor potential (TRP) protein family in DRGs were assayed by Western blot.@*RESULTS@#EA treatment significantly reduced mechanical allodynia and cold allodynia in OIPN rats (P<0.01). Notably, oxaliplatin treatment resulted in impaired microcirculatory blood flow and pathomorphological defects in DRGs (P<0.01). EA treatment increased the microcirculation blood flow and attenuated the pathological changes induced by oxaliplatin (P<0.01). In addition, the expression levels of Nrf2 and HO-1 were down-regulated, and the TRP protein family was over-expressed in the DRGs of OIPN rats (P<0.01). EA increased the expression levels of Nrf2 and HO-1 and decreased the level of TRP protein family in DRG (P<0.05 or P<0.01).@*CONCLUSION@#EA may be a potential alternative therapy for OIPN, and its mechanism may be mainly mediated by restoring the Nrf2/HO-1 signaling pathway.

ABSTRACT

OBJECTIVE@#To observe the effect of electroacupuncture (EA) at "Zusanli" (ST 36) on duodenal mast cells, nerve growth factor (NGF) and neurotrophic tyrosine kinase receptor type 1 (NTRK1), and to explore the mechanism of electroacupuncture at Zusanli (ST 36) on functional dyspepsia (FD).@*METHODS@#Sixty SPF-grade 10-day-old SD rats were randomly divided into a normal group, a model group, a ketotifen group and an EA group, 15 rats in each group. The FD model was prepared by iodoacetamide combined with rat tail clamping method in the model group, the ketotifen group and the EA group. The rats in the ketotifen group were injected intraperitoneally with ketotifen (1 mg•kg-1•d-1) for 7 days; the rats in the EA group were treated with EA at bilateral "Zusanli" (ST 36), with disperse-dense wave, frequency of 2 Hz/50 Hz and intensity of 0.5 mA, 20 min each time, once a day for 14 days. The gastric emptying rate and small intestinal propulsion rate in each group were observed; the morphology of duodenal mucosa was observed by HE staining; the toluidine blue staining was used to observe the number and degranulation of mast cells in duodenal mucosa; the protein and mRNA expressions of NGF, NTRK1 in duodenum were detected by Western blot and real-time PCR; the level of interleukin-1β (IL-1β) in duodenum was measured by ELISA.@*RESULTS@#Compared with the normal group, the gastric emptying rate and small intestinal propulsion rate in the model group were decreased (P<0.01); compared with the model group, the gastric emptying rate and small intestinal propulsion rate in the ketotifen group and the EA group were increased (P<0.01); the small intestinal propulsion rate in the EA group was higher than that in the ketotifen group (P<0.01). In the model group, local defects in duodenal mucosa were observed with a small amount of inflammatory cell infiltration; no obvious abnormality was found in duodenal mucosa of the other groups. Compared with the normal group, the mast cells of duodenal mucosa in the model group were increased significantly with significant degranulation; compared with the model group, the mast cells of duodenal mucosa in the ketotifen group and the EA group were decreased significantly, and the degranulation was not obvious. Compared with the normal group, the protein and mRNA expressions of NGF, NTRK1 as well as the level of IL-1β in duodenum in the model group were increased (P<0.01); compared with the model group, the protein and mRNA expressions of NGF, NTRK1 as well as the levels of IL-1β in duodenum in the ketotifen group and the EA group were decreased (P<0.01, P<0.05); compared with the ketotifen group, the mRNA expression of NGF, as well as the protein and mRNA expressions of NTRK1 in duodenum in the EA group were decreased (P<0.05, P<0.01).@*CONCLUSION@#EA at "Zusanli" (ST 36) could inhibit the activation of duodenal mast cells and regulate the expressions of NGF and its receptor to improve the low-grade inflammatory response of duodenum, resulting in treatment effect on FD.

ABSTRACT

OBJECTIVE@#To observe the effect of electroacupuncture (EA) at "Neiguan" (PC 6) on cardiac function of ventriculus sinister in rats with spontaneously hypertensive (SHR), and to explore the mediation effect of endothelin-1 (ET-1)/endothelial nitric oxide synthase (eNOS).@*METHODS@#Six 12-week-old male Wistar Kyoto (WKY) rats were taken as the normal group. Eighteen 12-week-old SHR were randomly divided into a model group, an EA group and a sham EA group, 6 rats in each group. The rats in the EA group were treated with EA (disperse-dense wave, 2 Hz/15 Hz in frequency, 1 mA in current intensity) at "Neiguan" (PC 6), 30 min each time, once a day for 8 weeks. The rats in the sham EA group were treated with superficial needling at "Neiguan" (PC 6) with no electrical stimulation applied. After treatment, the left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) were tested by echocardiographic analysis. The left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), heart rate (HR), the maximum rate of increase/decrease of left ventricular pressure (±dp/dtmax) were detected. The serum content of ET-1 was detected by ELISA. Western blot was used to evaluate the expression of ETAR, eNOS in myocardial tissue of left ventricular.@*RESULTS@#Compared with the normal group, LVEF, LVFS, +dp/dtmax/LVSP and -dp/dtmax/LVSP were decreased (P<0.01, P<0.05), while LVSP, LVEDP, +dp/dtmax and -dp/dtmax were increased (P<0.01) in the model group. Compared with the model group, LVEF, LVFS, +dp/dtmax/LVSP and -dp/dtmax/LVSP were increased (P<0.01, P<0.05), and LVSP and LVEDP were decreased (P<0.01) in the EA group. Compared with the normal group, the serum content of ET-1 and the expression of ETAR in myocardial tissue were increased (P<0.01), whereas expression of eNOS was decreased (P<0.01) in the model group. Compared with the model group, the serum content of ET-1 and the expression of ETAR in myocardial tissue were decreased (P<0.05), whereas expression of eNOS was increased (P<0.05) in the EA group.@*CONCLUSION@#EA intervention may alleviate hypertensive cardiac function damage by up-regulating the expression of eNOS protein in myocardial tissue, down-regulating the serum content of ET-1 and the expression of ETAR protein in myocardial tissue.

ABSTRACT

OBJECTIVE@#To compare the improvement effect between simultaneous electroacupuncture at antagonistic muscle and agonistic muscle and simple electroacupuncture at antagonistic muscle on spasticity degree, upper-extremity motor function and activity of daily living in patients with upper-extremity spasticity after stroke.@*METHODS@#A total of 60 patients with upper-extremity spasticity after stroke were randomized into a comprehensive group (30 cases, 1 case dropped off) and an antagonistic muscle group (30 cases, 2 cases dropped off). In the antagonistic muscle group, acupuncture was applied at Jianyu (LI 15), Binao (LI 14), Zhouliao (LI 12), Shousanli (LI 10), Waiguan (TE 5) and Houxi (SI 3), electric stimulation was attached to Jianyu (LI 15)-Binao (LI 14), Zhouliao (LI 12)-Shousanli (LI 10) and Waiguan (TE 5)-Houxi (SI 3), with discontinuous wave, 15 Hz in frequency. On the basis of the treatment in the antagonistic muscle group, acupuncture was applied at Tianquan (PC 2), Chize (LU 5), Jianshi (PC 5) and Daling (PC 7) in the comprehensive group, electric stimulation was attached to Tianquan (PC 2)-Chize (LU 5) and Jianshi (PC 5)-Daling (PC 7), with continuous wave, 5 Hz in frequency. The treatment was given once a day, 6 days a week for 4 weeks in the two groups. Before and after treatment, the scores of modified Ashworth scale (MAS), Fugl-Meyer assessment upper extremity scale (FMA-UE) and modified Barthel index (MBI) scale were observed in the two groups.@*RESULTS@#Compared before treatment, the MAS scores of elbow flexors and wrist flexors after treatment were decreased (P<0.05), the scores of FMA-UE and MBI scale after treatment were increased in the two groups (P<0.05). The scores of FMA-UE and MBI scale after treatment in the comprehensive group were higher than those in the antagonistic muscle group (P<0.05).@*CONCLUSION@#Simultaneous electroacupuncture at antagonistic muscle and agonistic muscle and simple electroacupuncture at antagonistic muscle can both improve the spasticity degree in patients with upper-extremity spasticity after stroke, however, the former can better restore motor function and improve activity of daily living.
