ABSTRACT
OBJECTIVE@#To compare the effect among ultrasound-guided electroacupuncture (EA) at suprahyoid muscle group, conventional acupuncture and conventional EA at suprahyoid muscle group on pharyngeal dysphagia after stroke, and to explore its biomechanical mechanism.@*METHODS@#A total of 120 patients with pharyngeal dysphagia after stroke were randomly divided into an observation group, a control-1 group and a control-2 group, 40 cases in each group. The patients in the observation group were treated with ultrasound-guided EA at suprahyoid muscle group; the patients in the control-1 group were treated with EA at Lianquan (CV 23), Wangu (GB 12) and Fengchi (GB 20), etc.; the patients in the control-2 group were treated with EA at suprahyoid muscle group according to anatomical location. The EA in the three groups were discontinuous wave, with frequency of 5 Hz and current intensity of 1 mA. The EA was given for 30 minutes, once a day, 6 times were taken as a course of treatment, and 4 courses of treatment were provided. The video floroscopic swallowing study (VFSS) was performed before and after treatment. The Rosenbek penetration-aspiration scale (PAS) score, the forward and upward movement distance of hyoid bone and thyroid cartilage, Ichiro Fujima ingestion-swallowing function score were recorded in the three groups, and the incidences of subcutaneous hematoma were recorded after treatment.@*RESULTS@#Compared before treatment, the PAS scores were reduced and the Ichiro Fujima ingestion-swallowing function scores were increased after treatment in the three groups (P<0.05); the PAS scores in the observation group were lower than those in the control-1 group and the control-2 group, and the Ichiro Fujima ingestion-swallowing function scores in the observation group were higher than those in the control-1 group and the control-2 group (P<0.05). After treatment, the forward and upward movement distance of hyoid bone and thyroid cartilage in the observation group and the control-2 group was increased (P<0.05), and the forward and upward movement distance of hyoid bone was increased in the control-1 group (P<0.05); the forward and upward movement distance of hyoid bone and thyroid cartilage in the observation group was longer than that in the control-1 group and the control-2 group (P<0.05). The incidence of subcutaneous hematoma in the observation group was 0% (0/40), which was lower than 20.0% (8/40) in the control-1 group and 47.5% (19/40) in the control-2 group (P<0.05).@*CONCLUSION@#Ultrasound-guided EA at suprahyoid muscle group could improve the swallowing function in patients with pharyngeal dysphagia after stroke by increasing the motion of hyoid laryngeal complex. Its effect and safety are better than conventional acupuncture and conventional EA at suprahyoid muscle group.

ABSTRACT
OBJECTIVE@#To observe the effect of electroacupuncture (EA) on the rehabilitation of knee joint function after anterior cruciate ligament (ACL) reconstruction.@*METHODS@#A total of 140 patients with ACL reconstruction were randomly divided into an observation group (58 cases recruited, 12 cases dropped out) and a control group (65 cases recruited, 5 cases dropped out). The patients in the control group were treated with routine rehabilitation treatment. The patients in the observation group, on the basis of the treatment in the control group, were treated with EA at Fengshi (GB 31), Futu (ST 32), Zusanli (ST 36), Shangjuxu (ST 37), Fenglong (ST 40), Xuanzhong (GB 39), Diji (SP 8) and Sanyinjiao (SP 6) on the affected side (2 Hz/100 Hz of dilatational wave, 2-5 mA). Each EA treatment lasted 20-30 min, twice a day for 7 days. The swelling degree (d), pain visual analogue scale (VAS), knee joint range of motion (ROM), scores of International Knee Documentation Committee (IKDC) subjective short form and scores of Lysholm were observed in the two groups 1 day, 1 month, 3 months, 6 months and 1 year after operation.@*RESULTS@#One month and 3 months after operation, the swelling degree (d) and VAS scores in the observation group were lower than those in the control group (0.05). One month, 3 months, 6 months and 1 year after operation, the ROM of the knee joint in the observation group was higher than that in the control group (<0.05), the IKDC score and Lysholm score were higher than those in the control group (<0.05). Within one year, there were no relaxations, fractures and other related complications in the two groups. The pivot shift test, anterior drawer test and the Lachman test were all negative.@*CONCLUSION@#EA combined with routine rehabilitation training could obviously reduce the pain of knee joint, improve the swelling degree, increase the ROM of knee joint, promote the functional recovery in patients with ACL reconstruction, which are superior to rehabilitation training alone.
ABSTRACT
OBJECTIVE@#To observe the expression of GABA receptor mRNA in different brain regions of the central nervous system in chronic inflammatory pain rats and the intervention effect of electroacupuncture (EA).@*METHODS@#A total of 48 SPF male SD rats were randomly divided into a blank control group, a model control group, an EA group and a sham EA group, 12 rats in each group. The model of chronic inflammatory pain was established by injecting Freund's complete adjuvant into the foot. The EA group was treated with EA 28 days after the model establishment. The "Housanli" (ST 36) and "Kunlun" (BL 60) were selected and treated with dilatational wave, 2 Hz/100 Hz in frequency, 0.5-1.5 mA for 30 min; EA was given only once. In the sham EA group, the same acupoints were selected but the needles were only inserted into subcutaneous area; EA was connected for 30 min without electrical stimulation. The behavior changes of mechanical pain threshold and thermal pain threshold before model establishment, 1 day, 3 days, 7 days, 14 days, 21 days and 28 days after the model establishment as well as emotional behavior 29 days after the model establishment were observed; the relative expressions of GABA receptor mRNA in anterior cingulate cortex, amygdala and hypothalamus were observed.@*RESULTS@#Compared with the blank control group, the change rates of mechanical pain threshold and thermal pain threshold in the model control group were decreased significantly 1 day, 3 days, 7 days, 14 days, 21 days, 28 days after model establishment (0.05). Compared with the blank control group, the expression of GABA receptor mRNA in the amygdala was decreased significantly in the model control group (<0.01); compared with the model control group and the sham EA group, the expression of GABA receptor mRNA in amygdala was increased after intervention in the EA group (<0.01).@*CONCLUSION@#Single treatment of EA could significantly increase the mechanical pain threshold and thermal pain threshold, improve abnormal emotional behavior in rats with chronic inflammatory pain, which may be related to the increasing of expression of GABA receptor mRNA in the amygdala.
ABSTRACT
OBJECTIVE@#To observe the therapeutic effects of different waves of electroacupuncture (EA) on knee osteoarthritis (KOA), and to explore the mechanism of different waves of EA on promoting cartilage repair.@*METHODS@#Ninety- seven patients with KOA were randomly divided into a dilatational wave group (32 cases, 2 cases dropped off), a continuous wave group (32 cases, 2 cases dropped off) and a discontinuous wave group (33 cases, 3 cases dropped off). The same acupoints of Xuehai (SP 10), Liangqiu (ST 34), Dubi (ST 35) and Neixiyan (EX-LE 4) were selected in the three groups. The dilatational wave (frequency of 2 Hz/10 Hz) was used in the dilatational wave group, the continuous wave (frequency of 10 Hz) was used in the continuous wave group, and the discontinuous wave (frequency of 10 Hz) was used in the discontinuous wave group. All the needles were retained for 30 min. All the treatment was given 3 times a week (on Monday, Wednesday and Friday) for 4 weeks. Lysholm knees scoring scale (LKSS) was used to evaluate the knee joint function before and after treatment, and the content of transforming growth factor-β1 (TGF-β1) in the joint effusion before and after treatment was determined by enzyme-linked immunosorbent assay (ELISA).@*RESULTS@#Compared before treatment, the total score and each score of LKSS were increased after treatment in the three groups (all <0.05). The improvements of total score, pain score, instability score, swelling score of LKSS in the continuous wave group and the dilatational wave group were superior to those in the discontinuous wave group (all <0.05). The content of TGF-β1 in the joint effusion in each group was increased after treatment (<0.05), and the improvement in dilatational wave group was superior to thoes in the continuous wave group and the discontinuous wave group (all <0.05).@*CONCLUSION@#The three different waves of EA could all improve the clinical symptoms of KOA, which may promote cartilage repair by increasing TGF-β1 content. The dilatational wave had the best overall effect, which can be used as a clinical optimal treatment.

OBJECTIVE@#To observe the direct intervention effects of electroacupuncture (EA) and non-steroid anti-inflammatory drugs (NSAIDs) on pain memory, and to explore their effects on cAMP/PKA/cAMP pathway in anterior cingulate gyrus (ACC).@*METHODS@#Fifty clean healthy male SD rats were randomly divided into a control group, a model group, an indomethacin group, an EA group and a sham EA group, 10 rats in each group. Except the control group, the pain memory model was established in the remaining four groups by twice injection of carrageenan at foot; 0.1 mL of 2%λ-carrageenan was subcutaneously injected at the left foot of rats; 14 days later, when the pain threshold of rats of each group returned to the basic level, the second injection was performed with the same procedure. The rats in the EA group were treated with EA at bilateral "Zusanli" (ST 36) for 30 min; the rats in the indomethacin group was treated with indomethacin intragastric administration with the dose of 3 mg/kg; the rats in the sham EA group was treated with EA without electricity at the point 0.3 mm forward "Zusanli" (ST 36) with the depth of 2 mm for 30 min; the rats in the control group was not given any invention. All the above interventions were performed 5 h, 1 d, 2 d and 3 d after the second injection of 2% λ-carrageenan. The left-side paw withdrawal thresholds (PWT) were observed before the first injection, 4 h, 3 d, 5 d after the first injection, before the second injection and 4 h, 1 d, 2 d, 3 d after the second injection. Three days after the second injection, the number of positive cells of cAMP, p-PKA, p-CREB and the number of positive cells of protein co-expression in the right ACC brain area were detected by immunofluorescence, and the relative protein expression of p-PKA and p-CREB were detected by Western blot.@*RESULTS@#Compared with the control group, the PWTs in the model group decreased significantly 4 h, 3 d and 5 d after the first injection and 1 d, 2 d and 3 d after the second injection (<0.05); compared with the control group, the positive expression of cAMP, p-PKA and p-CREB in the right ACC brain area in the model group increased significantly (<0.05), and the number of positive cells of the co-expression of cAMP/p-PKA and p-PKA/p-CREB also increased significantly (<0.05). Compared with the model group, indomethacin group and sham EA group, the PWTs in the EA group were increased significantly 1 d, 2 d and 3 d after the second injection (<0.05); compared with the model group, indomethacin group and sham EA group, the positive expression of p-PKA and p-CREB in the right ACC brain area in the EA group decreased significantly (<0.05), and the number of positive cells of co-expression of cAMP/p-PKA and p-PKA/p-CREB was decreased significantly (<0.05). Compared with the model group and sham EA group, the positive expression of cAMP in the right ACC brain area was decreased in the EA group (<0.05).@*CONCLUSION@#EA have a direct intervention effect on pain memory, which have significant advantage over NSAIDs in the treatment of chronic pain. The advantage effect of EA on pain memory may be related to the inhibition of cAMP/PKA/CREB pathway in ACC area.

OBJECTIVE@#To observe the effects of electroacupuncture (EA) on inflammatory response and intestinal mucosal barrier in obese rats with insulin resistance, and to explore the mechanism of EA on improving insulin resistance in rats.@*METHODS@#Among 45 Wistar male rats, 15 rats were randomly selected and fed with common diet. After eight weeks, 10 rats were randomly selected and divided into the normal group. The remaining 30 rats were fed with high-fat diet for 8 weeks to establish obesity model of rat, among 28 rats with successful model of obesity, 20 rats were randomly selected and divided into the model group and EA group, 10 rats in each one. At the same time, 3 rats in the model group and the EA group were randomly selected for hyperinsulinemia-euglycemic clamp operation to determine whether the insulin resistance model was successful. After model establishment, the rats in the EA group were intervented with EA at "Zhongwan" (CV 12), "Guanyuan" (CV 4), "Zusanli" (ST 36) and "Fenglong" (ST 40) with continuous wave, frequency of 2 Hz and intensity of 1 mA; "Zusanli" (ST 36) and "Fenglong" (ST 40) were used alternately on both sides; the needles were sustained for 10 min; EA was given once every other day, three times a week for a total of 8 weeks. During the intervention, the rats in the normal group and the model group were fixed but not intervented. The body mass and postprandial blood sugar were measured in each group before and after 8-week intervention. After 6-week intervention, 3 rats in each group were clamped to detect systemic insulin sensitivity. Before the rats were killed, blood was taken from the apex of the heart to detect the serum insulin content. After the rats were killed, the mRNA levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in liver and adipose tissue and occlidin and ZO-1 in colon tissue were detected by Real time-PCR; the protein expression levels of occludin and ZO-1 in colon tissue were detected by Western blot method.@*RESULTS@#Compared with the normal group, the body mass, postprandial blood sugar and serum insulin content in the model group were increased significantly, the glucose infusion rate (GIR) was decreased significantly (all <0.01), the mRNA expressions of TNF- and IL-6 in liver and adipose tissue were increased (<0.05, <0.01), the mRNA and protein expressions of ZO-1 in colon tissue were decreased significantly (both <0.01), and the mRNA expression of occludin was significantly decreased (<0.01). Compared with the model group, the body mass, postprandial blood sugar, serum insulin content, mRNA expressions of TNF-a and IL-6 in liver and adipose tissue were significantly decreased (<0.01, <0.05), GIR was significantly increased (<0.01), and the mRNA and protein expressions of ZO-1 in colon tissue were increased (<0.01, <0.05).@*CONCLUSION@#EA could decrease blood sugar and increase insulin sensitivity. Its mechanism may be related to inhibiting the expression of inflammatory factors and improving intestinal mucosal barrier.

ABSTRACT
Traditional Persian medicine (TPM) proposes a different viewpoint to the chronic diseases. Diagnosis and implemented treatment are based on individual differences among patients. Constipation or Ea'teghal-e-batn is a condition in which the patient develops difficult or painful defecation. Based on TPM concepts, the fifirst digestion step starts from halq (oral cavity), and ends via defecation from the maq'ad (anus). Avicenna believed that four faculties, ha'zemeh (digestive), ja'zebeh (absorptive), ma'sekeh (retentive) and da'fe'eh (propulsive), are involved in the process of digestion and absorption of the ingested food and expelling the waste materials. The bowel movement and appearance of the stool is a measure for evaluating the gastrointestinal healthy function. Defecation should be with no pain and fecal material should have no burning and acuity. Low food intake or foods with dry temperament, dryness of gastrointestinal tract, diaphoresis and heavy exercise as well as intestine sensory loss were discussed as main causes of constipation. Management of constipation in TPM includes dietary schemes, oil massages and subsequently simple herbal medicines. According to TPM theories, the fifirst step in treating a disease is the elimination of disease causes (asbabe- maraz) and also providing the causes of health (asbab-e-sehhat). Health care providers should know the proper condition which the herbal medicines should be administered in and be able to guide the patients about the benefifits and hazards of herbal remedies, commonly used in their living origin.
ABSTRACT
Objective: To construct the sponge vector which can target microRNA-186 (miR-186), and to create a stable EA. hy926 cell line that can knockdown miR-186. Methods: The miR-186 sponge sequence was chemically synthesized and cloned into lentiviral vector FV040. Then the FV040-miR-186-sponge recombinant plasmid together with the helper plasmids were cotransfected into the HEK293T cells by using lipofectamine 2000 to package lentivirus and the viral titer was determined. The FV040-control lentivirus (designated as the control group), and the FV040-miR-186-sponge (designated as the experiment group) were used to infect EA. hy926 cells for establishing stable cell lines. The fluorescent quantitative PCR (qPCR) method was used to detect the relative expression levels of miR-186 in the EA. hy926 cells in blank group, FV040-control group and FV040-miR-186 sponge group, respectively. Results: The cloned target sequence was identical with the designed miR-186 sponge sequence. The green fluorescence protein (GFP) was observed in the infected EA. hy926 cells. The lentivirus titre of viruses in the FV040-control group was 2×108 TU middot; mL-1, and which was 6 × 108 TU middot; mL-1 in FV040-miR- 186 sponge group. The EA. hy926 cell line stably expressed miR-186-sponge was established successfully and the infection rate was as high as 95%. The qPCR results indicated that the relative expression level of miR-186 in the EA. hy926 cells in FV040-miR-186-sponge group was lower than those in blank control group and FV040-control group (P<0. 01). Conclusion: The miR-186-sponge vector is successfully constructed, and the EA. hy926-miR- 186-sponge cell line with the stably decreased expression of miR-186 is established successfully.
ABSTRACT
OBJECTIVE: To observe the effect of electroacupuncture (EA) of "Zhongwan" (CV12) and "Zusanli" (ST36) in different combinations of stimulating parameters on intragastric pressure (IGP) in normal rats so as to explore their best combinations for promoting gastrointestinal mobility. METHODS: A total of 90 male SD rats were randomly divided into 6 EA groups：CV12-1 mA＋ST36-1 mA, CV12-1 mA＋ST36-2 mA, CV12-1 mA＋ST36-4 mA, ST36-1 mA＋CV12-1 mA, ST36-2 mA＋CV12-1 mA, and ST36-4 mA＋CV12-1 mA which the first acupoint was stimulated first, followed by the second in each group (n＝15 rats/group). Before (1 min), and 0-30 s, 30-60 s, 60 -90 s, and 90-120 s during EA stimulation of the left ST36 or CV12 first or later, the IGP was measured via an inserted intragastric balloon, a connected pressure transducer and an amplifier. Changes of the IGP were analyzed using 2×3×4 factorial design. RESULTS: 1) During 0-30 s, EA-CV12 showed an obvious inhibitory effect on IGP(P0.05). 2) Compared with the IGP level of 0-30 s, the IGP levels of 30-120 s were significantly decreased in all the groups (P0.05). CONCLUSION: Simultaneous EA stimulation of ST36 and CV12 has an antagonistic effect on IGP in normal rats, which is affected by the stimulating sequence, stimulating strength and time course.
ABSTRACT
OBJECTIVE: To compare the different effect of electroacupuncture (EA) at "Zusanli" (ST36) and "Chize" (LU5) of mother rats exposed to Nicotine during pregnancy and lactation on lung function and morphological changes in offspring rats, so as to explore the most effective acupoint for improving the development of lung in neonatal rats. METHODS: A total of 24 female pregnancy SD rats were randomly divided into 4 groups: normal control, model, EA-ST36 and EA-LU5 (n＝6 rats in each group). Rats of the normal group were treated by subcutaneous injection of normal saline, and those of the other 3 groups treated by subcutaneous injection of nicotine (1 mg•kg－1•d－1) beginning from the 6th day to about the 21st day of pregnancy (childbirth day) for nicotine exposure during pregnancy and lactation. The daily EA treatment (2 Hz /15 Hz，1 mA) was applied to bilateral ST36 and LU5 for 20 min, beginning from the 6th day of pregnancy to the 21st day (childbirth day). The lung function of the offspring rats including the peak inspiratory flow (PIF), peak expiratory flow (PEF), lung resistance (RL), exhalation resistance (RE)and lung dynamic compliance (Cdyn) was detected by using a lung function analysis system. Histopathological changes (severity of alveolarization) of the offspring rats' lung tissue were observed under microscope after H．E. stain. RESULTS: Compared with the normal group, the PIF, RL and RE values were significantly increased (P0.05)．. CONCLUSION: EA of ST36 and LU5 of mother rats experiencing nicotine exposure during pregnancy and lactation can improve the lung function and morphological changes in neonatal rats, and the effect of ST36 is relatively better.
