ABSTRACT

ObjectiveTo observe the effects of electroacupuncture at Zhongwan (CV12) on gastric nociceptive response induced by gastric acid stimulation and explore the underlying mechanisms associated with nuclei of the medullary viscerosensory and visceral motor neurons. MethodsTwenty SD rats were given intragastric administration of 0.5 mol/L diluted hydrochloric acid (0.5 ml/100 g) to induce gastric nociceptive response induction. Eight rats were randomly selected to record the gastric slow wave (GSW) area under the curve, and extracellular discharge frequency of neurons in the nucleus of the solitary tract (NTS) and dorsal motor nucleus of the vagus nerve (DMV) before intragastric administration and at 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, and 60 minutes after intragastric administration. The remaining 12 rats received electroacupuncture intervention at Zhongwan within 5 to 25 minutes after intragastric administration of diluted hydrochloric acid, with a duration of one minute. The GSW area under the curve and extracellular discharge frequency of NTS and DMV neurons were compared between the 1-minute intervals before and after electroacupuncture intervention. ResultsCompared to the baseline before intragastric administration, the area under the curve of GSW significantly increased at 1, 5, 10, 15, 20, and 25 minutes after intragastric administration, and the extracellular discharge frequency of excitatory neurons in the NTS (accounting for 90%, 57/63) significantly increased at 1, 5, 10, 15, 20, 25, 30, 35, and 40 minutes, both reaching peak values at 1 minute after intragastric administration (P<0.01 or P<0.05). The extracellular discharge frequency of inhibitory neurons in the DMV (accounting for 91%, 20/22) showed a non-significant increase at 1 minute after intragastric administration (P>0.05), but significantly decreased at other timepoints (P<0.05). Compared to the baseline before electroacupuncture intervention, the GSW area under the curve and the extracellular discharge frequency of excitatory neurons in the NTS significantly decreased (P<0.05), while the extracellular discharge frequency of inhibitory neurons in the DMV showed no significant difference (P>0.05). ConclusionElectroacupuncture at Zhongwan can improve gastric nociceptive response induced by gastric acid stimulation, possibly by reducing the transmission of visceral sensation and decreasing the excitability of NTS neurons in the medulla.

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

ObjectiveTo explore the possible peripheral analgesic mechanism of electroacupuncture (EA) at promimal and distal acupoints in treatment of myofascial pain syndrome (MPS). MethodsTwenty-four SD rats were randomly divided into blank group, model group, proximal group, and distal group, with six rats in each group. MPS model was prepared by “strike combined with centrifugal exercise” in all groups except for the blank group. After modeling, the rats in the proximal group received EA at the local myofascial trigger points (MTrPs), namely the Ashi points, with dilatational waves of frequency of 2/100 HZ and voltage of 2-4 V, current intensity depending on a slight trembling of the left lower limbs, once a day, 15min each time,for 14 days. The rats in the distal group received EA at “Yanglingquan” (GB 34) and “Yinlingquan” (SP 9), with the same operations as the proximal group. The rats in the blank group and the model group were only grasped and hedged, without other interventions. After intervention, the paw withdrawl mechanical threshold (PWMT) was measured, and variability between the left and right hind paws was calculated. Musculoskeletal ultrasound imaging and electromyography monitoring were performed on the left lower extremity vastus medialis. The morphological changes of vastus medialis muscle of the left lower extremity were observed by HE staining. The positive expression of substance P (SP), calcitonin gene-related peptide (CGRP), CD68 and CD206 in muscle tissue was detected by immunohistochemistry. Abdominal aortic serum interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), interleukin-10 (IL-10), and interleukin-8 (interleukin-8) were detected by ELISA. ResultsCompared to those in the blank group, the fibers of the vastus medial muscle of the rats in the model group were broken and distorted with thickness in variation, and the myofascia was broken, with fibrillation potential, enlarged muscle cells, inward moved nucleus, and widened muscle space; the variability of PWMT between the left and right hind paws significantly increased, as well as the levels of SP, CGRP, CD68, and CD206 in the vastus medialis muscle (P<0.01), and the serum IL-8 and TNF-αlevels were significantly elevated (P<0.05 or P<0.01). Compared to those in the model group, the muscle fibers in the proximal and distal group were complete in shape and arranged in an orderly manner, with continued non-broken myofascia, regular shape of muscle cells, and significantly reduced level of IL-8 (P<0.01); the amplitude and frequency of spontaneous discharge in the proximal group significantly decreased, as well as the variability of PWMT between the left and right hind paws, and the levels of SP, CGRP, and CD68 in the vastus medialis muscle, while the CD206 level increased significantly (P<0.05 or P<0.01 ); there was complex discharges in the distal group, with significantly decreased level of CD68 in the vastus medialis muscle and increased level of CD206 (P<0.01). Compared to the proximal group, the level of IL-8 in the distal group was significantly higher (P<0.05). ConclusionsEA at proximal acupoints can significantly improve the pain threshold and local muscle tissue morpho-logy in rats, and its mechanism may be related to reducing the levels of pain-causing substances and related inflammatory factors and promoting the polarization of macrophages. The analgesic effect of EA at distal acupoints is not obvious, and the mechanism is still unclear.

ABSTRACT

Objective:To explore whether the electroacupunture stimulation (ES) at acupoint Zusanli (ST36) can inhibit the bone loss caused by Staphylococcus aureus (SA) infection and its mechanism in a model of SA osteomyelitis.Methods:Twelve male C57 BL/6 mice aged 10 to 12 weeks were randomly divided into 2 even groups ( n=6) for SA infection + ES or SA infection only. After ES at ST36 was conducted for 4 weeks in the model of SA osteomyelitis, samples were harvested from the femora and tibiae. Micro-CT reconstruction was performed to detect trabecular bone volume fraction (BV/TV), trabecular number (Tb.N), trabecular thickness (Tb.Th), trabecular separation (Tb.Sp), connectivity density (Conn.Dn) to analyze changes in bone mass. Leptin receptor (LEPR) staining was performed to detect osteoblasts. Tartrate resistant acid phosphatase (TRAP) staining was used to detect the changes in osteoclasts. The changes in plasma inflammatory factors were detected by enzyme-linked immunosorbent assay (ELISA). Results:Micro-CT results showed that the BV/TV, Tb.N, Tb.Th, and Conn.Dn in the cancellous bone in the target areas in the SA + ES group were all higher than those in the SA group, LEPR immunofluorescence results indicated that the number of osteogenic precursor cells in the ES group was larger than that in the SA group, and serum ELISA indicated a decrease in inflammatory factors in the blood in the SA+ES group compared with the SA group. There were significant differences in the comparisons above ( P<0.05). There was no significant difference in the number of osteoclasts on the surface of trabecular bone between the 2 groups in TRAP staining. Conclusion:ES may slow down infectious bone destruction by inhibiting the inflammatory response induced by SA infection and by inducing aggregation and differentiation of mesenchymal stem cells into trabecular bone.

ABSTRACT

Objective:To investigate the effect of early intervention with electroacupuncture (EA) on the gut microbiota in a mouse model of post-traumatic stress disorder(PTSD).Methods:Totally 32 C57BL/6 mice were randomly assigned to the following 4 groups ( n=8 for each group): Control group, EA group, PTSD group and PTSD+ EA group.After 7 days acclimation, mice in the PTSD group and PTSD+ EA group were subjected to modified single prolonged stress (mSPS). Mice in the EA group and PTSD+ EA group received EA (2/15 Hz, 1 mA, dilatational wave, 30 min/d) on "Baihui" for 7 days. Mice in the Control group and PTSD group received false stimulation (stimulated the same acupiont without electricity) for 7 days. Seven days after the last stimulation, elevated plus maze test and fear conditioning test were conducted to observe the effect of EA on PTSD-like behavior of mice. At the same time, feces of the mice were collected for gut microbiota detection by 16S rRNA sequencing.SPSS 19.0 was used for statistical analysis.One-way ANOVA was used for multiple group comparison and Bonferrani test was done for further pairwise comparision. Results:(1) There were statistically differences in the open arm activity time of the elevated plus maze test and the immobility time in contextual and cued fear conditioning test among the four groups ( F=6.93, 5.26, 14.51, all P<0.01). In the elevated plus maze test, mice in PTSD group ((60.17±15.52) s) showed significant less time in the open arms than mice in Control group((96.37±14.62) s) and PTSD+ EA group ((86.89±15.02) s) (both P<0.05). In the fear conditioning test, mice in PTSD group ((121.99±29.67) s, (130.82±29.11) s) showed significant increased immobility time both in contextual and cued fear conditioning tests than mice in Control group((74.50±26.65) s, (39.50±23.52) s) and PTSD+ EA group ((76.77±22.60) s, (102.17±3.39) s)(both P<0.05). (2) There were no significant differences among the four groups in the alpha diversity of gut microbiota ( F=0.79-2.45, all P>0.05). (3)Correlation analysis showed that 13 gut microbiotas were negatively correlated with the immobility time in contextual fear conditioning test, 2 gut microbiotas were positively correlated with it; 7 gut microbiotas were negatively correlated with the immobility time in cued fear conditioning test, 1 gut microbiota was positively correlated with it; 3 gut microbiotas were positively correlated with time spent in open arms of elevated plus maze test. Conclusion:Early intervention with EA can improve anxiety-fear like behaviors and gut microflora disorder in PTSD model mice.

ABSTRACT

ObjectiveTo explore the possible mechanism of Tongdu Xingshen needling method (通督醒神针刺法) on post-stroke cognitive impairment. MethodsSD rats were randomly divided into a normal group (n=12), a sham surgery group (n=12), a model group (n=12), and a electroacupuncture group (n=13). The rats in the model group and electroacupuncture group were subjected to the wire bolus method to establish the rats model with learning memory impairment after cerebral ischaemia-reperfusion. After successful modelling, the rats in the electroacupuncture group were given electroacupuncture interventions at “Shenting (GV 24)” and “Baihui (GV 20)” once a day for 30 minutes for 14 days. The other three groups did not receive other interventions but grasp. A 5-day localisation navigation experiment was conducted on the 9th day of intervention, and a spatial exploration experiment was conducted on the 14th day of intervention to evaluate the learning and memory abilities of the rats. After the spatial exploration experiment, hippocampal tissues were taken from each group of rats, and the changes in the volume of cerebral infarction were observed by TTC staining; the changes in the morphology of pyramidal neurons and the density of dendritic spines in the CA1 area of the hippocampus were observed by Golgi staining; protein immunoblotting was used to detect the relative protein expression of the subunits of the α-amino-3-carboxy-5-methylisoxazole-4-propionic acid (AMPA) receptor including glutamate receptor 1 (GluR1), glutamate receptor 2 (GluR2), glutamate receptor 3 (GluR3) and auxiliary proteins TARPγ2, TARPγ8 in hippocampal tissues of rats in each group; the real-time fluorescence quantitative PCR was used to detect GluR1, GluR2, GluR3 mRNA levels in the hippocampal tissues of rats. ResultsIn the localisation navigation experiment, compared with the normal group and sham surgery group, the escape latency and total distance of rats in the model group were significantly extended (P<0.05) at day 1, 2, 3, 4, and 5; and the escape latency and total distance of rats in the electroacupuncture group tended to be significantly shorter than those in the model group (P<0.05). In the spatial exploration experiment, compared with the normal group and the sham surgery group, the number of rats crossing the platform in the model group was significantly reduced (P<0.05), and the number of crossings of the platform in the electroacupuncture group increased significantly (P<0.05). The results of TTC staining showed that the volume of cerebral infarction increased clearly in the model group compared with the sham surgery group (P<0.05), and apparently decreased in the electroacupuncture group compared with the model group (P<0.05). Golgi staining showed that the number of dendritic branches of pyramidal neurons and dendritic spines in hippocampal CA1 region significantly decreased in the model group compared with the normal group and the sham surgery group (P<0.05). The number of dendritic branches of pyramidal neurons and the density of dendritic spines in hippocampal CA1 region significantly increased in the electroacupuncture group compared with the model group (P<0.05). The protein relative expression levels of GluR1, GluR2, GluR3, TARPγ2 and TARPγ8, and the mRNA levels of GluR1, GluR2 and GluR3 in hippocampus decreased in the model group compared with the normal group and the sham surgery group (P<0.05). The protein relative expression levels of GluR1, GluR2, GluR3, TARPγ2 and TARPγ8, and the mRNA levels of GluR1, GluR2 and GluR3 in hippocampus increased in the electroacupuncture group compared with model group (P<0.05). ConclusionThe Tongdu Xingshen needling method can improve learning memory impairment after cerebral ischaemia-reperfusion, which may be related to up-regulation of the expression of AMPA receptor and their auxiliary protein TARP, and promoting the synaptic plasticity of hippocampal tissues.

ABSTRACT

ObjectiveTo explore the effect and possible mechanism of electroacupuncture (EA) at Fenglong (ST40) on liver lipid synthesis and insulin resistance (IR) in hyperlipidemic (HLP) rats. MethodEighteen rats were randomly divided into three groups, blank group, model group, and EA group, each consisting of six rats. The blank group rats were with fed a basic diet, while those in the model group and EA group were fed high-fat diet for 8 weeks. After modeling, the rats in the EA group received bilateral EA treatment at “Fenglong” (ST 40). The rats in the model group underwent daily binding treatment, once a day, continuously 5 days a week, for a total of 4 weeks. Following the intervention, the levels of triglycerides (TG) and free fatty acids (FFA) in liver tissue was determined using ELISA. Serum TG, FFA, fasting insulin (FINS), alanine transaminase (ALT), aspartate Transaminase (AST), tumor necrosis factor-ɑ (TNF-ɑ)and interleukin 6 (IL-6) were also measured. The fasting plasma glucose (FBG) assessed using a glucose meter and the homeostatic model assessment of insulin resistance (HOMA-IR) was calculated. Liver pathology was examined through HE staining and oil red O staining. The expression of hepatic sterol regulator binding protein 1c (SREBP1c), recombinant fatty acid synthase (FASN) and stearoyl-CoA desaturase 1 (SCD1) were detected through immunofluorescence. The protein expression levels of liver insulin receptor substrate 1 (IRS1) and tyrosine-phosphorylated insulin receptor substrate 1 (p-IRS1-Tyr) were determined via Western blot. ResultsWhen compared to the blank group, the model group of rats exhibited elevated serum and liver tissue levels of TG and FFA, as well as increased serum levels of AST, ALT, TNF-α, IL-6, FBG, FINS, and HOMA-IR (P<0.05). HE staining revealed disordered arrangements of liver cells, indicating widespread fatty degeneration. Oil red O staining showed abundant bright red lipid droplets within liver cell cytoplasm, indicating severe lipid accumulation. The average fluorescence intensity of SREBP1c, FASN, and SCD1 in liver tissue significantly increased (P<0.05), while p-IRS1-Tyr protein expression levels significantly decreased (P<0.05). In comparison to the model group, the EA group of rats showed significantly reduced serum and liver tissue levels of TG and FFA, along with decreased serum levels of AST, ALT, TNF-α, IL-6, FBG, FINS, and HOMA-IR (P<0.05). HE staining indicated more regular arrangements of liver cells, and oil red O staining revealed a significant reduction in liver cell lipid droplets, indicating a less severe degree of lipid accumulation. The average fluorescence intensity of SREBP1c, FASN, and SCD1 in liver tissue significantly decreased (P<0.05), while p-IRS1-Tyr protein expression levels significantly increased (P<0.05), with no significant difference in IRS1 protein expression (P>0.05). ConclusionEA at “Fenglong” (ST 40) can significantly decrease serum lipid in HLP rats, improves liver fat accumulation, and also ameliorate insulin resistance. The mechanism may be related to the inhibition of hepatic lipid synthesis molecule expression, reduced serum inflammatory factors, and an increase in insulin substrate receptor phosphorylation levels.

ABSTRACT

ObjectiveTo observe the effect of bilateral sequential repetitive transcranial magnetic stimulation on the motor function of upper limbs in stroke patients. MethodsFrom December, 2020 to December, 2022, 62 stroke inpatients in the Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine were included. They were randomly divided into control group (n = 31) and observation group (n = 31). Both groups accepted conventional medicine and rehabilitation, as well as electroacupuncture antagonistic muscle therapy. Before electroacupuncture, the observation group acceped low-frequency repetitive transcranial magnetic stimulation at primary motor cortex (M1) on the healthy side, followed by intermittent theta burst stimulation at M1 on the affected side, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), modified Barthel Index (MBI) and modified Ashworth Scale (MAS), and motor evoked potential (MEP) latency was compared before and after treatment. ResultsOne patient dropped down in the observation group, and no adverse event happened. After treatment, the scores of FMA-UE and MBI significantly increased (|t| > 9.953, P < 0.001), and the score of MAS and the latency of MEP significantly decreased (|t| > 5.043, P < 0.001) in both groups; while all of them were better in the observation group than in the control group (|t| > 2.237, P < 0.05). ConclusionBilateral sequential repetitive transcranial magnetic stimulation can effectively promote the recovery of upper limb motor function in stroke patients.

ABSTRACT

Objective:To investigate the effects and the possible mechanisms of Neiguan(PC6)and Gongsun(SP4)on the hypothalamic-pituitary-adrenal(HPA)axis in rats with functional dyspepsia(FD),thus to provide a theoretical basis for the clinical application of the Eight Confluent Points.Methods:Forty specific-pathogen-free Sprague-Dawley rats were divided into a blank group,a model group,an electroacupuncture(EA)group,and a Western medicine group by the random number table method,with 10 rats in each group.Rats in the blank group did not receive modeling or intervention.Rats in the other three groups were subjected to the FD with mood disorder model using the compound etiology modeling method.After the successful modeling,rats in the model group did not receive any interventions,rats in the Western medicine group received deanxit and mosaprid intervention,and those in the EA group received EA intervention on the ipsilateral Neiguan(PC6)and Gongsun(SP4)for 21 d.The sugar-water consumption rate was measured before the experiment and before and after interventions to assess the emotional status.The gastric emptying rate was measured after interventions to assess the gastrointestinal dynamics.The expression levels of hypothalamic corticotropin-releasing hormone(CRH),pituitary adrenocorticotropic hormone(ACTH),and adrenal corticosterone(CORT)were measured by enzyme-linked immunosorbent assay.Results:Compared with the blank group,the sugar-water consumption rate and the gastric emptying rate were decreased(P<0.01),and the hypothalamic CRH,pituitary ACTH,and adrenal CORT expression levels were increased(P<0.01)in the model group.Compared with the model group,the sugar-water consumption rate and the gastric emptying rate were significantly increased(P<0.01),while the expression levels of hypothalamic CRH,pituitary ACTH,and adrenal CORT were significantly decreased(P<0.01)in the EA group and the Western medicine group.The differences between the EA group and the Western medicine group were not statistically significant(P>0.05).Conclusion:The Eight Confluent Points Neiguan(PC6)and Gongsun(SP4)can improve the mood and gastrointestinal dynamics in FD rats,which may be achieved by down-regulating the hypothalamic CRH,pituitary ACTH,and adrenal CORT,as well as by correcting the HPA axis hyperfunction.

ABSTRACT

Objective:To investigate the effect and the mechanism of electroacupuncture(EA)on corpus striatum white matter injury in rats with focal cerebral ischemia(FCI).Methods:Forty-four specific-pathogen-free Sprague-Dawley rats were divided into a normal group(n=10),a sham-operation group(sham group,n=10),and a modeling group(n=24)using the random number table method.The normal group was a blank control.In the sham group,only the vessels and vagus nerve were isolated without embolization.The FCI rat model in the modeling group was replicated using the middle cerebral artery occlusion embolization method.The 20 successfully modeled rats were randomly divided into a model group and an EA group,with 10 rats in each group.Rats in the model group did not receive further treatment.Rats in the EA group received EA stimulation at Baihui(GV20)and the left Zusanli(ST36)24 h after the successful modeling,30 min each time,once a day for 14 d.On the 14th day of the experiment,rats in each group were scored for neurological deficits and then sacrificed,and brain tissues containing corpus striatum around the ischemic focus were paraffin-embedded from 5 rats in each group.Luxol fast blue(LFB)staining was used to detect damage changes in the white matter.The positive immunoreactive expression of myelin basic protein(MBP),myelin-associated growth inhibitor A(Nogo-A)and its receptor(NgR)in rat corpus striatum tissue was detected by immunohistochemistry staining,and then the protein expression of MBP,Nogo-A,and NgR in the corpus striatum tissue around the ischemic focus was determined by Western blotting.Results:Compared with the normal group and the sham group,the model group had a significantly higher neurological deficit score(P<0.05)and fiber bundle injuries in the corpus striatum white matter,evidenced by a significantly lower mean optical density value of corpus striatum LFB staining(P<0.05),a significantly lower MBP expression level(P<0.05),and significantly higher Nogo-A and NgR protein expression levels(P<0.05).Compared with the model group,the neurological deficit score was significantly lower(P<0.05),the mean optical density value of LFB staining was significantly higher(P<0.05),the MBP expression level was increased(P<0.05),and the expression levels of Nogo-A and NgR proteins were decreased(P<0.05)in the EA group.Conclusion:EA reduces the ischemia-induced corpus striatum white matter injury and improves neurological deficits.The mechanism may be related to the inhibition of Nogo-A/NgR activation.

Objective: To observe the effects of electroacupuncture (EA) at Neiguan (PC6) on arrhythmia during acute myocardial ischemia-reperfusion and the expression of connexin 43 (Cx43) in rats. Methods: A total of 40 Sprague-Dawley male rats were used. Ten rats were randomly selected as the blank group, and the remaining 30 rats were randomly divided into a model group and an EA group, with 15 rats in each group. Before modeling, rats in the EA group received one session of EA intervention at bilateral Neiguan (PC6) for 30 min; the other groups were treated with the same grasping and anesthesia for 30 min without intervention. PowerLab physiological recorder was used to record electrocardiograph within 30 min of infarction. After the experiment, cardiac tissue and serum were collected from rats. Hematoxylin-eosin (HE) staining was used to observe the morphological changes of myocardial tissue in the ventricular infarction area of rats in each group. The expression of Cx43 protein in the myocardium of each group was detected by Western blotting (WB). Enzyme-linked immunosorbent assay (ELISA) was used to determine the activity of Na+-K+-ATPase in myocardial tissue and the serum content of endogenous digitalis-like factor (EDLF) in rats. Results: There was no statistical difference in arrhythmia score between the EA group and the model group, but the total duration and average duration of arrhythmia in the EA group were decreased (P<0.01). HE staining showed that compared with the blank group, myocardial cells in the model group were disorganized and seriously damaged. The pathological changes in the EA group were similar to those in the model group, but the damage was relatively minor. The results of WB showed that compared with the blank group, the Cx43 expression in myocardial tissue of the model group was decreased (P<0.01); compared with the model group, the Cx43 expression in the EA group was increased (P<0.01); compared with the blank group, the Na+-K+-ATPase activity in myocardial tissue of the model group was significantly decreased (P<0.01); compared with the model group, the Na+-K+-ATPase activity in the EA group was increased (P<0.01). ELISA results showed that compared with the blank group, the serum EDLF content in the model group was significantly increased (P<0.01); compared with the model group, the EDLF content in the EA group was decreased (P<0.01). Conclusion: EA at Neiguan (PC6) can delay and reduce the onset of arrhythmia during myocardial infarction in the rat model of myocardial ischemia-reperfusion. Its mechanism of action may be related to the regulation of the Cx43 expression in myocardial tissue, improvement of the activity of Na+-K+-ATPase in myocardial tissue, and increase in the content of serum EDLF.

ABSTRACT

Objective:To observe the clinical efficacy of combining electroacupuncture with long needle sacral nerve acupuncture in the treatment of diabetic overactive bladder.Methods:A total of 90 patients with diabetic overactive bladder were randomly divided into an observation group and a control group, each of 45. In addition to the basic treatment for diabetes, the observation group received electroacupuncture combined with long needle sacral nerve acupuncture 5 times a week for 4 weeks, while the control group was given 5mg of oral solinax succinate once a day as a course of treatment. One week before the beginning of the experiment and one week before its end, urination diary cards were used to record the average number of times of daytime and nighttime urination daily, as well as any urgent urination and urinary incontinence during the week. Bladder overactivity syndrome score (OABSS), the bladder overactivity quality of life questionnaire (OAB-q), maximum urine flow rate (Qmax) and mean urine flow rate (Qave) were employed to quantify urination status, life quality and the urodynamics of the 2 groups before and after the treatment.Results:After the treatment, significant improvement was observed in the average weekly incidence of daytime and nighttime urination, of urgent urination and of urinary incontinence. The average OABSS, OAB-q, Qmax and Qave scores improved in both groups, but the experimental group showed significantly better improvement than the control group.Conclusion:Electroacupuncture combined with sacral nerve needling can significantly reduce the frequency of urination, relieve the symptoms of urgent urination and incontinence, and improve the rate of urine flow, improving the life quality of patients with diabetic overactive bladder.

ABSTRACT

Objective:To observe any effect of electroacupuncture on the expression of L1 cell adhesion molecule (L1CAM) in mice modeling Alzheimer′s disease (AD) and also any effect on learning and memory.Methods:Thirty male APP/PS1 mice were randomly divided into a model group, an electroacupuncture (EA) group, and a no acupuncture (NA) group, each of 10. All the animals were modeled as AD. Ten C57BL/6 mice served as a control group. The mice in the EA and NA groups were given continuous 50Hz EA at a current intensity of 1mA at and near the Baihui (GV20) and Shenshu (BL23) acupoints, respectively, once a day for 14 days, while the other two groups were not given any EA. The mice in the model and control groups continued to be routinely fed without any special treatment such as electroacupuncture. After the intervention, any behavioral changes were evaluated by using a Morris Water Maze, and the expression of L1CAM, PTEN and p53 protein in the hippocampus of each group was detected using western blotting.Results:Compared with the control group, the escape latency in positioning navigation experiments was significantly longer in the model group on the first 5 days of Morris Water Maze testing. Compared with the model group, the escape latency was significantly shorter in the EA group on days 2 to 5 of the Morris Water Maze testing, and the expression of L1CAM had increased significantly in the electroacupuncture group compared with the model group while PTEN and p53 expression had decreased significantly. The average escape latency of the NA group was significantly longer than that of the model group on days 2 to 5 of the Morris Water Maze testing. The average L1CAM expression in the NA group had decreased significantly, and the expression of PTEN and p53 protein had increased significantly more than in the EA group. The escape latency was negatively correlated with L1CAM expression but positively correlated with p53 protein and PTEN expression.Conclusion:L1CAM is involved in learning and memory processes, at least in mice. Electroacupuncture can improve the learning and memory of mice modeling Alzheimer′s, which may be due to its promoting the expression of L1CAM and inhibiting the expression of PTEN and p53.

ABSTRACT

Objective:To observe any effect of electroacupuncture applied to the Jialianquan points in treating post-stroke oropharyngeal dysphagia.Methods:Forty-five stroke survivors with oropharyngeal dysphagia were randomly divided into an electroacupuncture group ( n=15), a neuromuscular electrical stimulation group ( n=15) and a control group ( n=15). All groups received 30 minutes of routine swallowing function training 5 times a week for 3 weeks. The electroacupuncture group was additionally provided with 30 minutes of electroacupuncture applied to the Jialianquan (CV23) points, and the neuromuscular electrical stimulation group instead received 30 minutes of neuromuscular electrical stimulation over the bilateral submental muscles. Videofluoroscopic swallowing studies were performed before and after the 3 weeks of treatment. Standardized swallowing assessment was conducted producing functional oral intake scale ratings, modified barium swallow impairment profiles and the penetration-aspiration scale scores. Surface electromyography was also employed to evaluate submental muscle functioning through measuring the swallowing time, average EMG (AEMG) value and peak amplitude. Results:After the treatment, significant improvement was observed in all of the evaluations with both groups, but the average scores were significantly better in the electroacupuncture and neuromuscular electrical stimulation groups compared with the control group and significantly better in the electroacupuncture group than in the neuromuscular electrical stimulation group.Conclusion:Electroacupuncture at the Jialianquan point can significantly improve the swallowing of stroke survivors with oropharyngeal dysphagia. It is more effective than neuromuscular electric stimulation.

ABSTRACT

Objective:To evaluate the relationship between cannabinoid receptor 1 (CB1R) and the NOD-like receptor thermal protein domain-associated protein 3 (NLRP3) during the reduction of cerebral ischemia-reperfusion (I/R) injury by electroacupuncture (EA) preconditioning in rats.Methods:Forty SPF healthy male Sprague-Dawley rats, aged 7-9 weeks, weighing 250-280 g, were divided into 5 groups ( n=8 each) according to the random number table method: sham operation group (Sham group), cerebral I/R group (I/R group), EA preconditioning group (EA group), CB1R antagonist AM251+ EA preconditioning group (AM251+ EA group), and CB1R agonist WIN 55, 212-2 group (WIN group). Cerebral I/R was induced by middle cerebral artery occlusion (MCAO) in anesthetized animals. In EA group, EA preconditioning was performed, and the acupoint Baihui (GV20) was stimulated for 30 min with disperse-dense waves, the intensity of 1 mA and frequency of 2/15 Hz once a day for 5 consecutive days, and the model of cerebral I/R injury was developed at 24 h after the last EA. In AM251+ EA group, CB1R antagonist AM251 1 mg/kg was intraperitoneally injected at 30 min before each stimulation, and the remaining operations were the same as those previously described in EA group. CB1R agonist WIN 55, 212-2 1.5 mg/kg was intraperitoneally injected for 5 consecutive days, and the model of cerebral I/R injury was prepared at 24 h after the last injection in WIN group. Neurological behavior was assessed and scored at 3 days of reperfusion. Then the rats were sacrificed, and brains were removed, and the infarct volume was measured by TTC staining, and the tissues in the ischemic penumbra were extracted for determination of the expression of NLRP3, caspase-1 and interleukin-1bata (IL-1β) by Western blot. Results:Compared with Sham group, the percentage of cerebral infarct volume was significantly increased, the neurobehavioral score was decreased, and the expression of NLRP3, caspase-1 and IL-1β was up-regulated in I/R group ( P<0.05). Compared with I/R group, the percentage of cerebral infarct volume was significantly decreased, the neurobehavioral score was increased, and the expression of NLRP3, caspase-1 and IL-1β was down-regulated in EA and WIN groups ( P<0.05). Compared with EA group, the percentage of cerebral infarct volume was significantly increased, the neurobehavioral score was decreased, and the expression of NLRP3, caspase-1 and IL-1β was up-regulated in AM251+ EA group ( P<0.05). Conclusions:EA preconditioning may inhibit the activation of NLRP3 inflammasomes by activating CB1R, thus alleviating cerebral I/R injury in rats.

ABSTRACT

OBJECTIVE@#To investigate the effect of electroacupuncture (EA) at Neiguan (PC 6) on myocardial fibrosis in spontaneously hypertensive rats (SHRs), and to explore the contribution of interleukin-1 β (IL-1 β), insulin-like growth factor 1 (IGF-1), and transforming growth factor β 1 (TGF- β 1) to the effects.@*METHODS@#Nine 12-weeks-old Wistar Kyoto (WKY) male rats were employed as the normal group. Twenty-seven SHRs were equally randomized into SHR, SHR+EA, and SHR + sham groups. EA was applied at bilateral PC 6 once a day 30 min per day in 8 consecutive weeks. After 8-weeks EA treatment at PC 6, histopathologic changes of collagen type I (Col I), collagen type 1 (Col 1) and the levels of IGF-1, 1L-1 β, TGF- β 1, matrix metalloproteinase (MMP)-2 and MMP-9 were examined in myocardial tissure respectively.@*RESULTS@#After 8-weeks EA treatment at PC 6, the enhanced myocardial fibrosis in SHRs were characterized by the increased mean fluorescence intensity of Col I and Col 1 in myocardium tissue (P<0.01). All these abnormal alterations above in SHR + EA group was significantly lower compared with the SHR group (P<0.01). Meanwhile, the increased levels of IL-1 β, IGF-1, TGF-β 1 in serum or myocardial tissue of SHRs, diminished MMP 9 mRNA expression in SHRs were also markedly inhibited after 8 weeks of EA treatment (P<0.05 or P<0.01). Furthermore, the contents of IL-1 β, IGF-1, TGF-β 1 in myocardial tissue were positively correlated with the systolic blood pressure and hydroxyproline respectively (P<0.01).@*CONCLUSION@#EA at bilateral PC 6 could ameliorate cardiac fibrosis in SHRs, which might be mediated by regulation of 1L-1 β/IGF-1-TGF- β 1-MMP9 pathway.

ABSTRACT

OBJECTIVE@#To explore the effect of electroacupuncture (EA) intervention on the vasoconstriction of cerebral artery smooth muscle cells after cerebral infarction.@*METHODS@#Male Wistar rats were randomly divided into 3 groups by a random number table: the model group (n=24), the EA group (n=24), and the normal group (n=6). The model and the EA groups were divided into different time subgroups at 0.5, 1, 3, and 6 h after middle cerebral artery occlusion (MCAO), with 6 rats in each subgroup. MCAO model was established using intraluminal suture occlusion method. The EA group was given EA treatment at acupoint Shuigou (GV 26) instantly after MCAO for 20 min. The contents of cerebrovascular smooth muscle MLCK, the 3 subunits of myosin light chain phosphatase (MLCP) MYPT1, PP1c-δ and M20, as well as myosin-ATPase activity were detected using immunohistochemistry and Western blotting.@*RESULTS@#The overall expression level of the MYPT1 and PP1c-δ in the model group was significantly higher (P<0.01). After EA intervention, the 0.5 h group expression level was close to that of the normal group (P>0.05), and the other subgroups were still significantly higher than the normal group (P<0.01). After EA intervention, the expression level of each subgroup was significantly lower than the corresponding model group. There was a significant difference between the 0.5 and 1 h subgroups (P<0.01), while a difference was also observed between the 3 and 6 h subgroups (P<0.05). The dynamic change rule gradually increased with the prolongation of infarction time within 6 h after infarction.@*CONCLUSION@#EA intervention can inhibit contraction of cerebral vascular smooth muscle cells and regulate smooth muscle relaxation by regulating MLCK pathway.

ABSTRACT

OBJECTIVE@#To observe the effect of Tongdu Tiaoshen (promoting the circulation of the governor vessel and regulating the spirit) electroacupuncture (EA) pretreatment on pyroptosis mediated by peroxisome proliferators-activated receptor γ (PPARγ) of the cerebral cortex in rats with cerebral ischemia reperfusion injury (CIRI) and explore the potential mechanism of EA for the prevention and treatment of CIRI.@*METHODS@#A total of 110 clean-grade male SD rats were randomly divided into a sham-operation group, a model group, an EA group, an EA + inhibitor group and an agonist group, 22 rats in each group. In the EA group, before modeling, EA was applied to "Baihui" (GV 20), "Fengfu" (GV 16) and "Dazhui" (GV 14), with disperse-dense wave, 2 Hz/5 Hz in frequency, 1 to 2 mA in intensity, lasting 20 min; once a day, consecutively for 7 days. On the base of the intervention as the EA group, on the day 7, the intraperitoneal injection with the PPARγ inhibitor, GW9662 (10 mg/kg) was delivered in the EA + inhibitor group. In the agonist group, on the day 7, the PPARγ agonist, pioglitazone hydrochloride (10 mg/kg) was injected intraperitoneally. At the end of intervention, except the sham-operation group, the modified thread embolization method was adopted to establish the right CIRI model in the rats of the other groups. Using the score of the modified neurological severity score (mNSS), the neurological defect condition of rats was evaluated. TTC staining was adopted to detect the relative cerebral infarction volume of rat, TUNEL staining was used to detect apoptosis of cerebral cortical nerve cells and the transmission electron microscope was used to observe pyroptosis of cerebral cortical neural cells. The positive expression of PPARγ and nucleotide-binding to oligomerization domain-like receptor protein 3 (NLRP3) in the cerebral cortex was detected with the immunofluorescence staining. The protein expression of PPARγ, NLRP3, cysteinyl aspartate specific protease-1 (caspase-1), gasdermin D (GSDMD) and GSDMD-N terminal (GSDMD-N) in the cerebral cortex was detected with Western blot. Using the quantitative real-time fluorescence-PCR, the mRNA expression of PPARγ, NLRP3, caspase-1 and GSDMD of the cerebral cortex was detected. The contents of interleukin (IL)-1β and IL-18 in the cerebral cortex of rats were determined by ELISA.@*RESULTS@#Compared with the sham-operation group, the mNSS, the relative cerebral infarction volume and the TUNEL positive cells rate were increased (P<0.01), pyroptosis was severe, the protein and mRNA expression levels of PPARγ, NLRP3, caspase-1 and GSDMD were elevated (P<0.01); and the protein expression of GSDMD-N and contents of IL-1β and IL-18 were increased (P<0.01) in the model group. When compared with the model group, the mNSS, the relative cerebral infarction volume and the TUNEL positive cells rate were decreased (P<0.01), pyroptosis was alleviated, the protein and mRNA expression levels of PPARγ were increased (P<0.01), the protein and mRNA expression levels of NLRP3, caspase-1 and GSDMD were decreased (P<0.01), the protein expression of GSDMD-N was reduced (P<0.01); and the contents of IL-1β and IL-18 were lower (P<0.01) in the EA group and the agonist group; while, in the EA + inhibitor group, the protein expression of PPARγ was increased (P<0.01), the protein and mRNA expression levels of NLRP3 and GSDMD were decreased (P<0.01, P<0.05), the mRNA expression of caspase-1 was reduced (P<0.01); and the contents of IL-1β and IL-18 were lower (P<0.01). When compared with the EA + inhibitor group, the mNSS, the relative cerebral infarction volume and the TUNEL positive cells rate were decreased (P<0.05, P<0.01), pyroptosis was alleviated, the protein and mRNA expression levels of PPARγ were increased (P<0.01), the protein and mRNA expression levels of NLRP3, caspase-1 and GSDMD were decreased (P<0.01), the protein expression of GSDMD-N was reduced (P<0.01); and the contents of IL-1β and IL-18 were declined (P<0.01) in the EA group. Compared with the agonist group, in the EA group, the relative cerebral infarction volume and the TUNEL positive cells rate were increased (P<0.05, P<0.01), the mRNA expression of PPARγ was decreased (P<0.01) and the protein expression of GSDMD-N was elevated (P<0.05); and the contents of IL-1β and IL-18 were higher (P<0.01).@*CONCLUSION@#Tongdu Tiaoshen EA pretreatment can attenuate the neurological impairment in the rats with CIRI, and the underlying mechanism is related to the up-regulation of PPARγ inducing the inhibition of NLRP3 in the cerebral cortex of rats so that pyroptosis is affected.

ABSTRACT

OBJECTIVE@#To observe the immediate analgesic effect of electroacupuncture (EA) combined with diclofenac sodium on acute gouty arthritis (AGA).@*METHODS@#A total of 90 patients with AGA were randomly divided into a low-dose medication (LM) group (30 cases, 1 case was eliminated, 1 case dropped off), a conventional medication (CM) group (30 cases, 1 case dropped off) and a combination of acupuncture and medication (AM) group (30 cases ). The LM group was given oral administration of 50 mg diclofenac sodium sustained-release capsule; the CM group was given oral administration of 100 mg diclofenac sodium sustained-release capsule; on the basis of the treatment of LM group, the AM group was treated with electroacupuncture at ashi points, Dadu (SP 2), Taichong (LR 3), Taibai (SP 3), Neiting (ST 44), Sanyinjiao (SP 6), Zusanli (ST 36) and Yinlingquan (SP 9) on the affected side, and Taichong (LR 3) and Zusanli (ST 36), Sanyinjiao (SP 6) and Yinlingquan (SP 9) were connected to electroacupuncture respectively, continuous wave, 2 Hz in frequency. The visual analogue scale (VAS) scores of pain before treatment and after 10 min, 2 h, 4 h and 6 h of treatment completion, joint tenderness and swelling scores before treatment and after 10 min and 6 h of treatment completion were compared, and the rate of diclofenac sodium addition within 24 h after treatment completion was recorded among the three groups.@*RESULTS@#After 10 min of treatment completion, the scores of VAS, joint tenderness and joint swelling in the AM group were lower than those before treatment (P<0.05), and the VAS score in the AM group was lower than that in the other two groups (P<0.05). After 2, 4 and 6 h of treatment completion, the VAS scores of the three groups were lower than those before treatment (P<0.05), and the scores in the AM group were lower than those in the LM group (P<0.05). After 6 h of treatment completion, the joint tenderness scores of the three groups and the joint swelling scores of the AM group and the CM group were lower than those before treatment (P<0.05), and the joint tenderness and swelling scores of the AM group were lower than those of the LM group (P<0.05). The rate of diclofenac sodium addition was 3.3 % (1/30) and 3.4 % (1/29) in the AM group and the CM group, respectively, which were lower than 17.9% (5/28) in the LM group (P<0.05).@*CONCLUSION@#Electroacupuncture combined with diclofenac sodium have a good immediate analgesic effect in the treatment of AGA, and have the advantages of small dosage of analgesic drugs and less adverse reactions.
