Objective
To summarize and critically assess the evidence from randomized controlled trials (RCTs) of acupuncture in treating dry eye syndrome (DES) according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and the Cochrane Collaboration recommendations.Methods
A search of PubMed, the Cochrane Central Register of Controlled Trials, ClinicalTrials.gov and Embase was made from their inception to August 2016, as well as Chinese, Japanese, and Korean databases. Two reviewers independently selected RCTs and assessed the methodological quality. Meta-analysis and the level of evidence were processed by RevMan 5.3 and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.Results
After selection, 8 trials were subjected to our systematic review. The methodological quality was low generally. The 3-10 weeks follow-up showed that acupuncture improved the tear film break-up time (BUT) (MD=1.33, 95% CI=1.01-1.66, 619 participants). The mean difference of Schirmer’s test was 1.73 mm (95%CI=1.28-2.18, 618 participants) between the acupuncture group and the control group. The subjective variables exhibited no significant differences.Conclusion
The low methodological quality of the trials does not suggest drawing firm conclusions on the value of acupuncture therapy for DES. Acupuncture treatment may have some effects on the tear film BUT and Schirmer’s test, but not on the subjective symptoms. Well-planned large-scale high-quality RCTs are needed to make it clear whether acupuncture is effective in treating DES.3.
Objective
To observe the effect of electroacupuncture (EA) at Huantiao (GB 30) and Weizhong (BL 40) on thigmesthesia, gait function, and expression levels of serum immunoglobulin G (IgG) and immunoglobulin M (IgM) in rabbits with lumbar intervertebral disc herniation (LIDH).Methods
Forty healthy New Zealand rabbits were randomly divided into a blank control group, a model group, an EA at acupoint group and an EA at non-acupoint group, with 10 rabbits in each group. The LIDH pathological model of rabbit was established using the self-made LIDH model maker. The thigmesthesia and gait function of rabbits were recorded by Siegal method. The serum IgG and IgM expression levels were detected by enzyme-linked immunosorbent assay.Results
EA at Huantiao (GB 30) and Weizhong (BL 40) could improve the clinical symptoms of thigmesthesia and gait function, and inhibit the expressions of serum IgG and IgM in the LIDH rabbits, which were significantly different compared with those in the model group and EA at non-acupoint group.Conclusion
EA at Huantiao (GB 30) and Weizhong (BL 40) can improve the clinical symptoms of LIDH rabbits, which is associated with inhibition of the serum IgG and IgM expressions and reduction of the immunoinflammatory factor release. This may be one of the mechanisms of EA at Huantiao (GB 30) and Weizhong (BL 40) in the treatment of LIDH.4.
Objective
To observe the effect of electroacupuncture (EA) at Jiaji (EX-B 2) points plus hydro-acupuncture with sinomenine hydrochloride for low back pain caused by compression fractures in the elderly.Methods
Ninety-five elderly in-patients with low back pain caused by compression fractures were randomly divided into an observation group and an EA group according to the visit sequence. Both groups received the same basic treatment. In the EA group, 48 cases were treated with EA at Jiaji (EX-B 2) points plus the basic therapy; 47 cases in the observation group received the basic treatment plus EA and hydro-acupuncture with sinomenine hydrochloride at Jiaji (EX-B 2) points. The levels of osteoprotegerin (OPG) and interleukin-1β (IL-1β) in peripheral blood were measured by enzyme-linked immunosorbent assay (ELISA) before and at the 21st day of treatment in both groups. Oswestry disability index (ODI) and visual analog scale (VAS) scores were used to analyze the clinical efficacy.Results
After treatment, the OPG content in the observation group was higher with statistical significance compared with that before treatment in the observation group and after the treatment in the EA group, respectively (both P<0.05); the content of IL-1β, ODI and VAS scores were lower than those before treatment in the observation group and after treatment in the EA group with statistical significances (all P<0.05).Conclusion
The combination of EA and hydro-acupuncture with sinomenine hydrochloride at Jiaji (EX-B 2) points is effective for low back pain caused by compression fractures in the elderly, and is superior to EA at Jiaji (EX-B 2) points alone.5.
Objective
To observe the therapeutic effect of electroacupuncture (EA) at local points plus point injection on House-Brackmann facial nerve function classification grade (H-B) and facial disability index (FDI) in pregnant women with Bell palsy (BP).Methods
A total of 40 eligible BP patients during pregnancy were randomized into a treatment group (n=20) and a control group (n=20). The treatment group was intervened by EA at Sizhukong (TE 23), Tongziliao (GB 1), Sibai (ST 2), Quanliao (SI 18), Yifeng (TE 17), Dicang (ST 4), Jiache (ST 6) and point injection at Zusanli (ST 36) and Yanglingquan (GB 34) on the affected side, 30 min every time, 10 sessions as a course, for 2 courses in total while control group by EA with the same points, manipulation and courses as the treatment group.Results
After the treatment, the H-B classification in the treatment group was better than that in the control group, with a significant inter-group difference (P<0.05); after the treatment, the change of FDI score in the treatment group was significantly different from that in the control group (P<0.05).Conclusion
EA at local points plus point injection can produce a more significant efficacy than EA in the treatment of BP during pregnancy.6.
Objective
To observe the clinical effect of electroacupuncture (EA) at four sacral points on overactive bladder syndrome.Methods
A total of 120 female patients with overactive bladder syndrome were allocated to a treatment group of 80 cases and a control group of 40 cases on a voluntary basis. The patients in the treatment group received EA at four sacral points, and the treatment was given three times a week for 6 consecutive weeks, while the patients in the control group received oral administration of M-receptor antagonist tolterodine tartrate, which was given 4 mg each time, once a day for 6 consecutive weeks. Then the symptom scores were compared between the two groups before and after treatment.Results
At the end of treatment, the symptom scores showed statistical significant differences in comparing with those before treatment in both groups (both P<0.01); the symptom score in the treatment group was lower than that in the control group, showing a statistically significant difference (P<0.05).Conclusion
EA at four sacral points is an effective method for overactive bladder syndrome.7.
Objective
To determine whether six weeks' of acupuncture has a positive effect on plantar flexion muscle strength and whether electroacupuncture (EA) has a greater effect than manual acupuncture (MA) on plantar flexion, so that the most beneficial method of acupuncture can be established for strengthening muscles.Methods
A randomized controlled trial with parallel groups. A total of 20 participants were randomly assigned to three groups: a control/non-acupuncture group (n=6), a manual acupuncture group (MAG) (n=8) and an electroacupuncture group (EAG) (n=6). MAG and EAG received three 25-minute treatments per week for 6 weeks. The control group continued with their normal training activity and received no treatment. The maximal voluntary contraction (MVC) of the ankle plantar-flexors at 30° per second was measured using Biodex system 3.Results
Both MA and EA had a positive effect in increasing plantar flexion strength. The likelihood for this happening was high; 69% for MA and 92% for EA when compared with the control group. However the effect size was small for both groups. There was only a trivial difference in the effect size between the EAG and the MAG in regards to average plantar flexion torque.Conclusion
EA and MA have a beneficial effect on plantar flexion muscle strength compared with the control group in healthy population.8.
Objective
To reveal the action mechanism and efficacy of electroacupuncture (EA) plus external application of Wei Ling Xian (Radix Clematidis) extract in treating knee osteoarthritis (KOA), for providing theoretical evidence and novel plan for the treatment of KOA.Methods
Totally 284 inpatients were divided into an EA group and an observation group by the random number table, 142 cases in each group. The EA group was intervened by EA, ultrashort waves, and oral administration of Glucosamine Hydrochloride capsules; while the observation group was by external application of Wei Ling Xian (Radix Clematidis) extract at topical area in addition to the treatment given to the EA group. The intervention lasted 14 d in both groups. X-ray examination of knee joint was ordered before and after treatment, as well as the detection of positive expression of matrix metalloproteinase-1 (MMP-1) in cartilage of knee joint, hyaluronic acid (HA) and interleukin-1β (IL-1β) in the inflammatory effusion; the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) and visual analogue scale (VAS) were adopted to evaluate the clinical efficacy.Results
In the observation group, the X-ray examination result of knee joint was significantly improved, the positive expressions of MMP-1 and IL-1β content were significantly decreased, the level of HA was increased, WOMAC and VAS scores dropped, and the total effective rate was 91.5%, which were significantly different from those in the EA group (P<0.05).Conclusion
EA plus external application of Wei Ling Xian (Radix Clematidis) extract can produce a more significant efficacy in treating KOA compared to ordinary EA treatment.9.
Objective
To observe the effect of reward alteration following acupuncture for morphine withdrawal rats on the behavior and neuronal discharges in the medial prefrontal cortex (mPFC).Methods
The Sprague-Dawley (SD) rats were randomly allocated into a model group, a confinement group, an electroacupuncture (EA) group, and a control group. Rats with morphine addiction were made by intraperitoneal injection of naloxone (same dose injection of saline for rats in the control group), followed by a 2-week morphine withdrawal. Acupuncture and confinement were completed during the morphine withdrawal period. Upon withdrawal, the rats received conditioned place preference (CPP) training and open field test. The multi-channel neural signal processor was used in the electrophysiological experiment to measure the neuronal discharges in different subareas of prefrontal cortex in CPP box and aversion box.Results
Rats in the model group and the confinement group spent longer period of time in CPP box than those in the EA group and the control group (all P<0.01); there was no statistically significant difference between the EA group and the control group. The total distances of movement by rats in the model group and the confinement group were longer than those in the EA group and the control group (all P<0.01). The mPFC neuronal discharge frequencies were compared between morphine preference box and aversion box. The mPFC neuronal discharge frequencies in the model group and the confinement group were higher than those in the EA group and the control group (all P<0.05); there was no statistically significant difference between the EA group and the control group.Conclusion
Acupuncture can effectively interfere with the reward alteration following morphine withdrawal, possibly because of its involvement with the mPFC neuronal discharges.10.
Objective
To investigate the effects of electroacupuncture (EA) at Neiguan (PC 6) and Baihui (GV 20) by observing the changes of CCAAT/enhancer-binding protein(C/EBP) homologous protein (CHOP) and caspase-12 gene expressions in rats after cerebral ischemia-reperfusion injury (IRI), and explore whether the apoptosis pathway of endoplasmic reticulum stress (ERS) is involved in the protective mechanisms of EA.Methods
Sixty rats were randomly assigned to five groups (12 in each group): a normal control group (group A), a sham-operation group (group B), an operation group (group C), an Edaravone group (group D) and an EA group (group E). The cerebral IRI rat model was induced by middle cerebral artery occlusion (MCAO) using intraluminal monofilament. 2,3,5-triphenyl tetrazolium chloride (TTC) staining was adopted in the measurement of cerebral infarction volume. Real-time polymerase chain reaction (RT-PCR) was used to determine the mRNA expressions of CHOP and caspase-12.Results
Compared with group A and group B, the volume of cerebral infarction and mRNA expressions of CHOP and caspase-12 in group C, group D and group E were increased, with statistical significances (P<0.05 or P<0.01); compared with group C, the volume of cerebral infarction and mRNA expressions of CHOP and caspase-12 in group D and group E were decreased significantly (P<0.05 or P<0.01); there were no significant differences between group D and group E in comparing the above items (P>0.05).Conclusion
EA at Neiguan (PC 6) and Baihui (GV 20) can effectively suppress the volume of cerebral infarction. Furthermore, the underlying mechanism of EA at Neiguan (PC 6) and Baihui (GV 20) is possibly related to the down-regulation of CHOP and caspase-12 mRNA expressions, so as to decrease cell apoptosis.11.
Objective
To explore the clinical effects of electroacupuncture (EA) at Zusanli (ST 36) and Fenglong (ST 40) in treating senile dementia.Methods
A total of 74 patients were randomly divided into an EA group and a medication group based upon the random digital table, 37 cases in each group. EA at Zusanli (ST 36) and Fenglong (ST 40) was given in the EA group, once every day, for six treatments per week. Donepezil Hydrochloride Tablets were given to the medication group, 5 mg per time and once a day in the former four weeks, 10 mg per time and once a day after 4 weeks, oral administration before sleep at night. The courses of the treatment were 12 weeks in both groups. The scores of mini-mental state examination (MMSE) and Barthel index (BI) were observed before and after the treatment, for processing the comparative analysis of the clinical effects after the course of the treatment.Results
The total effective rate was 86.5% in the EA group and 70.3% in the medication group. The therapeutic effect was better in the EA group than that in the medication group, and the difference between the two groups was statistically significant (P<0.05). MMSE and BI scores after the treatment in the two groups were all elevated than those of the same groups before the treatment (P<0.05, P<0.01). The improving situation was obviously better in the EA group than that in the medication group, and the difference between the two groups was statistically significant (P<0.05).Conclusion
EA at Zusanli (ST 36) and Fenglong (ST 40) is affirmative in the therapeutic effect for senile dementia and can also improve the cognitive function and enhance the patients’ quality of life.12.

Objective
To observe the clinical effect of electroacupuncture (EA) plus self-made Jiawei Jinhuanggao (Supplemented Golden Yellow Paste) for gouty arthritis.Methods
A total of 80 cases with gouty arthritis were randomly allocated into an observation group (n=40) and a Western medication group (n=40). Cases in the observation group received EA and external application of self-made Jiawei Jinhuanggao (Supplemented Golden Yellow Paste), whereas cases in the Western medication group took Colchicine and Allopurinol tablets orally. After 10 d of treatment, the pain, joint swelling and uric acid in blood were observed. In addition, the follow-up was conducted 6 months after end of the treatment to evaluate the long-term effect.Results
After treatment, there were no between-group statistical differences in pain and uric acid in blood (P>0.05); and there were between-group statistical differences in joint swelling and relapse rate (P<0.05). The total effective rate was 97.5% in the observation group, versus 95.0% in the Western medication group, showing no statistical difference (P>0.05).Conclusion
EA plus Jiawei Jinhuanggao (Supplemented Golden Yellow Paste) has safe and long-term efficacy for gouty arthritis efficacy.13.
Objective
To observe the effect of electroacupuncture (EA) and herbal cake-partitioned moxibustion on anxiety and depression in patients with Crohn’s disease (CD) in remission.Methods
Sixty CD cases were randomly allocated into an EA group (n=30) and an herbal cake-partitioned moxibustion group (n=30) using the random number table by the ratio of 1:1. In addition, 30 healthy subjects were included in a control group. Bilateral Tianshu (ST 25), Qihai (CV 6) and Zhongwan (CV 12) were used in the EA and herbal cakepartitioned moxibustion groups. The treatment was done 3 times a week, for a total of 12 weeks. The efficacy was evaluated using self-rating anxiety scale (SAS), self-rating depression scale (SDS) and traditional Chinese medicine (TCM) symptom scores.Results
Before treatment, the SAS and SDS scores in CD patients were remarkably higher than those in healthy subjects. After EA or herbal cake-partitioned moxibustion treatment, the SAS and SDS scores were significantly decreased in both groups, showing significant intra-group differences (P<0.05); the symptom scores of abdominal pain (severity, frequency and duration), bowel sounds/flatus and general fatigue were significantly decreased, showing significant intra-group differences (P<0.05); however, there were no between-group statistical differences (P>0.05).Conclusion
Both EA and herbal cake-partitioned moxibustion can significantly decrease abnormally high SAS and SDS scores in CD patients as well as TCM symptom scores. The two therapies share similar effects in alleviating common symptoms and improving anxiety and depression.14.
Objective
To observe the effects of electroacupuncture (EA) of different frequencies on the expression levels of substance P (SP) and vasoactive intestinal peptide (VIP) in the colon of rats with slow transit constipation (STC).Methods
One hundred healthy male Sprague-Dawley (SD) rats were randomly divided into a normal group, a model group, a low-frequency EA group, a high-frequency EA group and a variable-frequency EA group, with 20 rats in each group. The rats in the normal group were fed with normal diet. The rats in the other groups were fed with phenethylpiperidine in the diet at a dose of 8 mg/(kg·bw) per day, for 120 d, to establish the STC model. Rats in the normal group and the model group did not receive any treatment; rats in the low-frequency EA group were treated with 2 Hz continuous wave EA, rats in the high-frequency EA group were treated with 100 Hz continuous wave EA, and rats in the variable-frequency EA group were treated with 2 Hz/100 Hz sparse-dense EA. The current intensity of the EA was determined by the slight vibration of the rat limbs without painful screaming. The intervention was performed once a day, 15 min/time for continuous 15 d. After treatment, the intestinal transit function and the expression levels of SP and VIP in the colon of the rats in each group were determined.Results
After treatment, the defecation duration of the first dark stool in the model group was significantly longer than that in the normal group (P<0.05); the defecation durations of the first dark stool in the low-frequency EA group, high-frequency EA group and variable-frequency EA group were significantly shorter than the duration in the model group (all P<0.05); compared with the low-frequency EA group, the first dark stool defecation duration of rats in the variable-frequency EA group was significantly shorter (P<0.05); compared with the normal group, the SP and VIP expression levels in the colon of the model group were significantly decreased (both P<0.01); the SP and VIP expression levels in the colon of the low-frequency EA group, the high-frequency EA group and the variable-frequency EA group were significantly higher than those in the model group (all P<0.05); compared with the high-frequency EA group, the SP expression levels in the colon in the low-frequency EA group and the variable-frequency EA group were significantly increased (both P<0.05); compared with the low-frequency EA group, the VIP expression levels in the colon in the high-frequency EA group and the variable-frequency EA group were significantly increased (both P<0.05).Conclusion
EA improves the intestinal function of STC model rats by regulating the expression levels of SP and VIP in rat colon. The EA stimulation with 100 Hz continuous wave, 2 Hz/100 Hz sparse-dense wave shows a better improvement in the colonic transit function in STC rats, followed by 2 Hz continuous wave.15.
Objective
To explore the action mechanism of electroacupuncture (EA) in improving the gastric motility of rats with diabetic gastroparesis (DGP).Methods
Forty-eight healthy Sprague-Dawley (SD) rats were randomly assigned into four groups: a normal group (group A), a model group (group B), a group of EA at acupoints (group C), and a group of EA at non-acupoints (group D), 12 rats in each group. The animal model of DGP was established by intraperitoneal injection of streptozotocin (STZ) plus high glucose and fat diet. The blood glucose, urine glucose and gastric emptying rate (GER) were observed. The content of insulin (INS) in serum and ghrelin in gastric antrum tissue were detected by enzyme linked immunoassay (ELISA). The expression of growth hormone secretagogue receptor mRNA (GHSR mRNA) in gastric antrum tissue was detected by real-time fluorescent quantitative polymerase chain reaction (PCR).Results
Compared with group A, blood glucose and urine glucose increased significantly (P<0.01), GER, content of serum insulin, the content of ghrelin and expression of GHSR mRNA in gastric antrum tissue decreased significantly (P<0.05 or P<0.01) in group B. Compared with group B, blood glucose and urine glucose decreased significantly (P<0.05), GER, the content of insulin in serum, the content of ghrelin and expression of GHSR mRNA in gastric antrum tissue increased significantly (P<0.05 or P<0.01) in group C.Conclusion
EA at acupoints can down-regulate the content of blood and urine sugar, and promote gastric emptying, which is possibly related to the regulation of serum insulin, and the expressions of ghrelin and GHSR mRNA in gastric antrum.16.
Objective
To observe the clinical efficacy of electroacupuncture (EA) on Alzheimer’s disease (AD).Methods
A total of 50 AD patients were randomly allocated into a Western medication (WM) group (n=25) and an acupuncture plus medication (APM) group (n=25). Patients in the WM group took oral huperzine A capsules. In addition to huperzine A capsules, patients in the APM group also received EA at Shenting (GV 24), Baihui (GV 20), Dazhui (GV 14), Fengfu (GV 16), Mingmen (GV 4) and Yongquan (KI 1). The needles on the above points were connected to G6805-II electric stimulator [3 pairs: Shenting (GV 24) and Baihui (GV 20); Dazhui (GV 14) and Fengfu (GV 16); and bilateral Yongquan (KI 1)]. The needles were retained 25 min. The treatment was done once a day, and 10 times made up a course of treatment. The patients received a total of 3 treatment courses. There was a 3-day interval between two courses. The mini-mental state examination (MMSE) and Hasegawa dementia scale revised (HDS-R) were conducted before and after treatment. The clinical efficacies were evaluated when the treatment was completed.Results
Before treatment, there were no between-group statistical differences in MMSE and HDS-R scores (both P>0.05). After treatment, the MMSE and HDS-R scores in the APM group were significantly higher than those in the WM group (both P<0.05). The total effective rate in the APM group was 88.0%, versus 76.0% in the WM group, showing a statistical difference (P<0.05).Conclusion
EA is effective for AD and can improve clinical symptoms in AD patients.17.
Objective
To observe the effects of electroacupuncture (EA) of three different frequencies (2 Hz, 80 Hz and 2 Hz/80 Hz) on the free radicals in hippocampus of vascular dementia (VD) model mice.Methods
A total of 100 Kunming mice were randomly divided into a sham operation group, a model group, a 2 Hz EA group, an 80 Hz EA group and a 2 Hz/80 Hz EA group, with 20 mice in each group. The ischemia-reperfusion VD model was established by repeated blockade of bilateral common carotid arteries. Mice in EA groups began EA treatment on the 4th day after the operation. Baihui (GV 20), Dazhui (GV 14), Geshu (BL 17) and Zusanli (ST 36) were punctured and then connected to EA instrument, with different waves of 2 Hz, 80 Hz or 2 Hz/80 Hz (10 min/time) applied accordingly, once a day. During the jumping stand experiment, the learning performance, memory performance and hippocampal calcitonin gene-related peptide (CGRP), nitric oxide synthase (NOS), malondialdehyde (MDA), changes in superoxide dismutase (SOD) and true choline esterase (TChE) were observed. In hippocampus, the CGRP level was determined by radioimmunoassay; the MDA level was determined by thiobarbituric acid colorimetric method; the activities of NOS and TChE were determined by spectrophotometry; the activity of SOD was determined by xanthine oxidase method.Results
Compared with the sham operation group, the performances of learning and memory decreased significantly in the model group (P<0.01); in hippocampus, the CGRP level decreased, the MDA level increased, the activities of NOS and TChE increased, and the activity of SOD decreased in the model group. Compared with the model group, the learning and memory performances of the EA groups were significantly improved (P<0.05 or P<0.01); in hippocampus, the CGRP level increased, the MDA level decreased, the NOS and TChE activities decreased, and the SOD activity increased (P<0.05 or P<0.01). Among EA groups, the 2 Hz/80 Hz EA group was superior to the 2 Hz EA group and the 80 Hz EA group (P<0.05 or P<0.01).Conclusion
EA can improve the cognitive impairment of mice with ischemia-reperfusion VD. The mechanism may be related to the improvement of cerebral blood circulation, regulation of the central neurotransmitters, fighting lipid peroxidation and promoting nerve cell repair. The therapeutic effects of EA with different frequencies were different, and the intervention effect by EA at 2 Hz/80Hz is the most significant.18.
Objective
To observe different efficacies of low-frequency electroacupuncture (EA) on pancreatic endocrine system in male and female patients with simple obesity due to spleen deficiency-related dampness.Methods
A total of 80 simple obesity patients were assigned to a male group (n=37) and a female group (n=43). Both groups received a 30-minute low-frequency EA at Yinlingquan (SP 9), Sanyinjiao (SP 6), Zusanli (ST 36), Fenglong (ST 40), Quchi (LI 11), Tianshu (ST 25), Zhongwan (CV 12), Shuifen (CV 9), Qihai (CV 6) and Guanyuan (CV 4). The treatment was done once a day, and 10 times made up a course of treatment. Patients in both groups were treated for 2 courses. Then the changes in body mass index (BMI), serum insulin, insulin antibodies and leptin level in the two groups were observed and analyzed.Results
After treatment, the BMI, serum insulin, insulin antibodies and leptin levels were significantly reduced in both groups (P<0.01 or P<0.05); the BMI and serum insulin concentration were more significantly reduced in the male group than those in the female group (both P<0.01); and the leptin level was more significantly reduced in the female group than that in the male group (P<0.01).Conclusion
EA can significantly regulate BMI and pancreatic endocrine system in both men and women with simple obesity; however, there is a gender difference: better effect for men in reducing BMI and serum insulin and better effect for women in reducing serum leptin level.19.
Objective
To observe the effect of point-moxibustion on gastrointestinal motility, mRNA and protein expressions of ghrelin and growth hormone secretagogue receptor 1a (GHSR-1a) in lateral septal nucleus of rats with diabetic gastroparesis (DGP), and to investigate the central regulatory mechanism of DGP treatment with point-moxibustion.Methods
Forty SPF-grade Sprague-Dawley (SD) rats were randomly divided into a blank group, a model group, an electroacupuncture (EA) group and a point-moxibustion group, with 10 rats in each group. A DGP rat model was established by intraperitoneal injection of 2% streptozotocin (STZ) with 8-week irregular high-sugar and high-fat diet in the model group, the EA group and the point-moxibustion group; and rats in the blank group were injected intraperitoneally with 0.1 mmoL/L (pH 4.5) citric acid-sodium citrate buffer with 8-week normal diet. Eight weeks later, rats in the EA group were treated by EA at Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6); while rats in the point-moxibustion group were treated by point-moxibustion at Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6) for successive 15 d. Rats in the blank group and the model group were fixed as the control without intervention. After treatment, intestinal propulsion rate and gastric emptying rate were measured. The mRNA and protein expressions of ghrelin and GHSR-1a in the lateral septal nucleus were detected by real-time polymerase chain reaction (RT-PCR) and Western blot (WB).Results
Compared with the blank group, the intestinal propulsion rate and gastric emptying rate of the model group were significantly lower (both P<0.01); compared with the model group, the intestinal propulsion rate and gastric emptying rate of the EA group and the point-moxibustion group increased significantly (all P<0.05). The mRNA and protein expressions of ghrelin and GHSR-1a were lower in the model group than those in the blank group (all P<0.01). The mRNA and protein expressions of ghrelin and GHSR-1a were significantly higher in the EA group and the point-moxibustion group than those in the model group (all P<0.05). There were no statistically significant differences between the EA group and the point-moxibustion group (all P>0.05).Conclusion
Point-moxibustion at Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6) can increase the intestinal propulsion rate and gastric emptying rate of DGP rats, and promote the mRNA and protein expressions of ghrelin and GHSR-1a in the central nervous system. The mechanism may be related to the activation of ghrelin pathway in hypothalamic arcuate nucleus-lateral septal nucleus.20.
