Effect of percutaneous electrical stimulation at the Baliao point on preventing postpartum urinary retention after labor analgesia

BACKGROUND Anesthetic drugs used in labor analgesia also paralyze the bladder muscle by blocking the sacral plexus,thereby affecting maternal postpartum spontaneous urination and increasing the risk of postpartum urinary retention(PUR).AIM To analyze the effect of percutaneous electrical stimulation at the Baliao point combined with biofeedback therapy for PUR prevention.METHODS We selected 182 pregnant women who received labor analgesia in obstetrics between June 2022 and December 2023.They were divided into the combined therapy group(transcutaneous electrical stimulation of the Baliao point combined with biofeedback therapy)and the control group(biofeedback therapy alone).The first spontaneous urination time,first postpartum urine volume,bladder residual urine volume,postpartum hemorrhage volume,pre-urination waiting time,PUR incidence,adverse reactions,and the intervention’s clinical efficacy were compared between the two groups.RESULTS The first spontaneous urination time after delivery was more delayed(2.92±1.04 h vs 3.61±1.13 h,P<0.001),with fewer initial postpartum urine(163.54±24.67 mL vs 143.72±23.95 mL,P<0.001),more residual bladder urine(54.81±10.78 mL vs 65.25±13.52 mL,P<0.001),more postpartum bleeding(323.15±46.95 mL vs 348.12±45.03 mL,P=0.001),and longer waiting time for urination(0.94±0.31 min vs 1.29±0.42 min,P<0.001),in the control group than in the combined therapy group.The control group also had higher PUR incidence(4.65%vs 15.85%,P=0.016).Both groups had no adverse reactions,but the clinical total efficacy rate of the intervention was significantly higher in the combined therapy group than in the control group(95.35%vs 84.15%,P=0.016).CONCLUSION Percutaneous electrical stimulation of the Baliao point combined with biofeedback can significantly promote postpartum micturition of parturients with labor analgesia,thereby effectively preventing PUR occurrence.

Research on the Different Frequencies of Transcutaneous Electrical Acupoint Stimulation for Postpartum Pelvic Girdle Pain

Objective:To observe the clinical effect of different frequencies of transcutaneous electrical acupoint stimulation in treating postpartum pelvic girdle pain and promoting postpartum rehabilitation.Methods:From January to September 2022,300 patients with pelvic girdle pain after spontaneous delivery in a hospital in Shaanxi Province were selected and randomly divided into three groups,low frequency,high frequency,and alternating frequency,with 100 cases in each group.In addition to routine postpartum care and psychological counseling,the three groups received transcutaneous electrical acupoint stimulation at low-frequency(2 Hz,)high-frequency(100 Hz),and alternating frequency(2/100 Hz),respectively.The differences in initial pain,pain scores before and after treatment,satisfaction with analgesic effect,and postpartum rehabilitation effect were evaluated among the three groups of patients.Results:There was a significant correlation between maternal age and postpartum pelvic girdle pain(P<0.001),but no correlation was observed between newborn birth weight and postpartum pelvic girdle pain(P>0.05).After 1d/2d of treatment,the pain scores and rehabilitation effect of patients in the alternating-frequency group and low-frequency group were significantly better than those in the high-frequency group,and the postpartum curative effect of patients in the alternating-frequency group was the best,followed by the low-frequency group,and the high-frequency group;the differences were statistically significant(P<0.001).Among the three groups,the alternating-frequency group had the highest satisfaction with the analgesic effect and the highest rate of selecting the same analgesic regimen the next time;the differences were statistically significant(P<0.001).Conclusion:Transcutaneous electrical acupoint stimulation at different frequencies is safe and effective in treating postpartum pelvic girdle pain and beneficial to postpartum rehabilitation.Sparse-dense wave stimulation is effective in treating postpartum pelvic girdle pain.It has the best effect in promoting postpartum rehabilitation and the highest patient satisfaction.Therefore,its application in clinical practice is highly recommended.

Transcutaneous electrical acupoint stimulation in adult patients receiving gastrectomy/colorectal resection:A randomized controlled trial

BACKGROUND Acupuncture promotes the recovery of gastrointestinal function and provides analgesia after major abdominal surgery.The effects of transcutaneous electrical acupoint stimulation(TEAS)remain unclear.AIM To explore the potential effects of TEAS on the recovery of gastrointestinal function after gastrectomy and colorectal resection.METHODS Patients scheduled for gastrectomy or colorectal resection were randomized at a 2:3:3:2 ratio to receive:(1)TEAS at maximum tolerable current for 30 min immediately prior to anesthesia induction and for the entire duration of surgery,plus two 30-min daily sessions for 3 consecutive days after surgery(perioperative TEAS group);(2)Preoperative and intraoperative TEAS only;(3)Preoperative and postoperative TEAS only;or(4)Sham stimulation.The primary outcome was the time from the end of surgery to the first bowel sound.RESULTS In total,441 patients were randomized;405 patients(58.4±10.2 years of age;247 males)received the planned surgery.The time to the first bowel sounds did not differ among the four groups(P=0.90;log-rank test).On postoperative day 1,the rest pain scores differed significantly among the four groups(P=0.04;Kruskal–Wallis test).Post hoc comparison using the Bonferroni test showed lower pain scores in the perioperative TEAS group(1.4±1.2)than in the sham sti-mulation group(1.7±1.1;P=0.04).Surgical complications did not differ among the four groups.CONCLUSION TEAS provided analgesic effects in adult patients undergoing major abdominal surgery,and it can be added to clinical practice as a means of accelerating postoperative rehabilitation of these patients.

Changes in plasma calcitonin gene-related peptide and serum neuron specific enolase in rats with acute cerebral ischemia after low-frequency electrical stimulation with different waveforms and intensities

Following acute cerebral ischemia in rats, plasma calcitonin gene-related peptide decreased and the level of serum neuron specific enolase and the volume of the infarction increased. Square-wave and triangular-wave electrical stimulation with low or high intensities could increase the plasma calcitonin gene-related peptide, decrease the serum neuron specific enolase and reduce the infarction volume in the brain in rats with cerebral ischemia. There was no significant difference between different wave forms and intensities. The experimental findings indicate that low-frequency electrical stimulation with varying waveforms and intensities can treat acute cerebral ischemia in rats.

Effect of low-frequency pulse percutaneous electric stimulation on peripheral nerve injuries at different sites

BACKGROUND： The postoperative recovery of nerve function in patients with peripheral nerve injury is always an important problem to solve after treatment. The electric stimulation induced electromagnetic field can nourish nerve, postpone muscular atrophy, and help the postoperative neuromuscular function. OBJECTIVE： To observe the effects of low-frequency pulse percutaneous electric stimulation on the functional recovery of postoperative patients with peripheral nerve injury, and quantitatively evaluate the results of electromyogram （EMG） examination before and after treatment. DESIGN ： A retrospective case analysis SETTING： The Sixth People＇s Hospital affiliated to Shanghai Jiaotong University PARTICIPANTS： Nineteen postoperative inpatients with peripheral nerve injury were selected from the De- partment of Orthopaedics, the Sixth People＇s Hospital affiliated to Shanghai Jiaotong University from June 2005 to January 2006, including 13 males and 6 females aged 24-62 years with an average of 36 years old. There were 3 cases of brachial plexus nerve injury, 3 of median nerve injury, 7 of radial nerve injury, 3 of ul- nar nerve injury and 3 of common peroneal nerve injury, and all the patients received probing nerve fiber restoration. Their main preoperative manifestations were dennervation, pain in limbs, motor and sensory disturbances. All the 19 patients were informed with the therapeutic program and items for evaluation. METHODS： ① Low-frequency pulse percutaneous electric stimulation apparatus： The patients were given electric stimulation with the TERESA cantata instrument （TERESA-0, Shanghai Teresa Health Technology, Co., Ltd.）. The patients were stimulated with symmetric square waves of 1-111 Hz, and the intensity was 1.2-5.0 mA, and it was gradually adjusted according to the recovered conditions of neural regeneration following the principle that the intensity was strong enough and the patients felt no obvious upset. They were treated for 4- 24 weeks, 10-30 minutes for each time, 1-3 times a day, and 6 weeks as a course. ② EMG examination was applied to evaluate the recoveries of recruitment, motor conduction velocity （MCV） and sensory conduction velocity （SCV） before and after treatment. The patients were examined with the EMG apparatus （DIS- A2000C, Danmark） before and after the treatment of percutaneous electric stimulation. ③Standards for evaluating the effects included cured （complete recovery of motor functions, muscle strength of grade 5, no abnormality in EMG examination）, obviously effective [general recovery of motor function, muscle strength of grade 4, no or a few denervation potentials, motor conduction velocity （MCV） and sensory conduction velocity （SCV）], improved （partial recovery of motor function, muscle strength of grade 3, denervation potentials and reinneration potentials, slowed MCV and SCV, invalid （no obvious changes of motor function）. MAIN OUTCOME MEASURES： ① Ameliorated degree of the nerve function of the postoperative patients with peripheral nerve injury treated with percutaneous electric stimulation; ② Changes of EMG examination before and after treatment. RESULTS： All the 19 postoperative patients with peripheral nerve injury were involved in the analysis of results. ① Comparison of nerve function before and after treatment in 19 patients with peripheral nerve injury of different sites： For the patients with radial nerve injury （n=7）, the nerve functions all completely recovered after 8-week treatment, and the cured and obvious rate was 100% （7/7）; For the patients with brachial plexus nerve injury （n=3）, 1 case had no obvious improvement, and the cured and obvious rate was 67% （2/3）; For the patients with common peroneal nerve injury （n=3）, the extension of foot dorsum generally recovered in 1 case of nerve contusion after 4-week treatment, and the cured and obvious rate was 67% （2/3）; For the patients with median nerve injury （n=3）, muscle strength was obviously recovered, and the cured and obvious rate was 100% （3/3）; For the patients with ulnar nerve injury （n=3）, 1 case only had recovery of partial senses, and the cured and obvious rate was 67% （2/3）. Totally 9 cases were cured, 7 were obviously effective, 1 was improved, and only 2 were invalid. After 4 courses, the cured rate of damaged nerve function after four courses was 47% （9/19）, and effective rate was 89% （17/19）.② Comparison of EMG examination before and after treatment： Before and after percutaneous electric stimulation, he effective rates of recruitment, MCV and SCV were 89% （17/19）, 58% （11/19）, 47% （9/19） respectively, and there were extremely obvious differences （P〈 0.01）. CONCLUSION： ①Low-frequency pulse percutaneous electric stimulation can improve the nerve function of postoperative patients with peripheral nerve injury of different sites, especially that the injuries of radial nerve and median nerve recover more obviously. ②Percutaneous electric stimulation can ameliorate the indexes of EMG examination, especially the recruitment, in postoperative patients with peripheral nerve injury.

Effects of cervical low-frequency electrical stimulation with various waveforms and densities on body mass,liver and kidney function,and death rate in ischemic stroke rats

Low-frequency electrical stimulation has resulted in favorable effects in the treatment of post-stroke dysphagia. However, the safety of cervical low-frequency electrical stimulation remains unclear because of numerous nerves and blood vessels in the neck. In the present study, rats with ischemic stroke underwent low-frequency electrical stimulation, and systemic and local effects of electrical stimulation at different densities and waveforms were investigated. Electrical stimulation resulted in no significant effects on body mass, liver or kidney function, or mortality rate. In addition, no significant adverse reaction was observed, despite overly high intensity of low-frequency electrical stimulation, which induced laryngismus, results from the present study suggested that it is safe to stimulate the neck with a low-frequency electricity under certain intensities.

Effect of transcutaneous electrical acupoint stimulation combined with palonosetron on chemotherapy-induced nausea and vomiting: a single.blind,randomized, controlled trial

Background: Chemotherapy?induced nausea and vomiting adversely affects the quality of life of patients who receive chemotherapy via intravenous infusion or transcatheter arterial chemoembolization(TACE). This study aimed to investigate the clinical effects of transcutaneous electrical acupoint stimulation(TEAS) on nausea and vomiting after TACE.Methods: A total of 142 patients who received TACE with cisplatin for primary or metastatic liver cancer were assigned to the active?acupuncture(n = 72) or placebo?acupuncture(n Hegu(LI4), Neiguan(P6), an= 70) groups using a covariate?adaptive randomization at a ratio of 1:1. The acupointsd Zusanli(ST36) were stimulated twice daily for 6 days. The effects of TEAS on nausea and vomiting were assessed by using occurrence rate and severity of these symptoms. Anorexia scale and M. D. Anderson Symptom Inventory(MDASI) scores were secondary endpoints and were used to assess the effect of TEAS on patient appetite and quality of life. The safety of the treatments was also monitored.Results: Between the two groups, the differences in occurrence rates and severities of nausea and vomiting after TACE were not significant(all P > 0.05). From the second day after TACE, anorexia scores were significantly lower in the active?acupuncture group than in the placebo?acupuncture group and continued to decrease over time with treat?ment(all P values less than 0.01). On days 0, 1, and 2, the mean MDASI scores for the active?acupuncture group were slightly lower than those for the placebo?acupuncture group, but the differences were not statistically significant(all P > 0.05). No significant differences were found between the two groups in the occurrence rate of any adverse event(P > 0.05).Conclusion: TEAS appears to be a safe and effective therapy to relieve patients' gastrointestinal discomfort after chemotherapy.

TRANSCUTANEOUS ACUPOINT ELECTRIC STIMULATION IN COMBINATION WITH ENFLURANE ANESTHESIA FOR CRANIOCEREBRAL OPERATIONS

The reinforcing effect of transcutaneous acupoint electric stimulation(TAES)on enflurane anesthesia during craniotomy was studied.One hundred and ten neurosurgical patientswere randomly divided into three groups.Anesthesia was maintained with enflurane in Group A(n=40).In Group B,enflurane anesthesia was supplemented by TAES with Han’s acupoint nerve stimu-lator(HANS)at Hegu(LI 4),Yuyao(EX-HN 4)and Fengchi(GB 20)points on the operated side(n=40).In Group C,enflurane anesthesia was supplemented by TAES and scalp infiltration with 0.5％procaine solution(n=30).The results showed that the minimum alveolar concentration(MAC)of enflurane in Group B and C decreased by 37.8-47.0％and 42.1-66.1％respectively than thatin Group A.The hemodynamics was more stable during operation,and the patients recovered after operation in group B and C.It was concluded that TAES with HANS significantly the anesthetic effect and decreased the side effects of enflurane during operation,and that the triplecombination of TAES,enflurane and scalp infiltration with procaine appeared to be a better anestheticmethod for craniotomy.

Clinical observation of acupoint injection combined with nerve electrical stimulation in the treatment of post-stroke dysphagia

Background:Post-stroke dysphagia is one of the common clinical symptoms in the rehabilitation department of primary hospitals,which seriously affects the quality of life of patients and their families.Majority of medical workers have comprehensively studied post-stroke dysphagia as it easily induces inhalation pneumonia,asphyxia,and many other complications.At present,many methods for post-stroke dysphagia have been proved to be effective.With regard to comprehensive treatment effect,patient compliance,technology promotion difficulty,grassroots hospital operability,and other factors,we found that acupoint injection combined with nerve electrical stimulation is a good method worthy of promotion.Methods:A total of 130 patients with dysphagia after stroke were randomly divided into nerve electrical stimulation group(n=41),acupoint injection group(n=40),and comprehensive treatment group(nerve electrical stimulation plus acupoint injection,n=49).The therapeutic effect in each group was evaluated before treatment and 20 days after treatment using the improved water swallow test,video fluoroscopic swallowing study,and standardized swallowing assessment.Results:After 20 days of treatment,significant differences were noted in each group.The scores of improved water swallow test decreased from 4.10±0.74 to 2.12±0.95 in the nerve electrical stimulation group,4.00±0.78 to 2.28±1.04 in the acupoint injection group,and 4.16±0.77 to 1.73±0.79 in the comprehensive treatment group;video fluoroscopic swallowing study scores increased from 3.71±2.16 to 5.05±2.111 in the nerve electrical stimulation group,3.80±1.94 to 5.20±1.942 in the acupoint injection group,and 3.73±2.22 to 6.24±2.21 in the comprehensive treatment group;and standardized swallowing assessment scores of the three groups also decreased from 35.13±3.38 to 28.17±3.42,34.66±3.46,and 34.48±3.26 to 26.39±3.86,respectively.The overall scores of each group after treatment were significantly different from those before treatment(P<0.05),indicating that both nerve electrical stimulation and acupoint injection were effective for post-stroke dysphagia;the scores of nerve electrical stimulation group and acupoint injection group were similar,but those of the comprehensive treatment group were significantly better than the single treatments(P<0.05).It shows that the two treatment methods have synergistic effect,and combined treatments have more benefits.Conclusion:Nerve electrical stimulation and acupoint injection have a synergistic therapeutic effect on post-stroke dysphagia.The combined treatment is more beneficial to patients with post-stroke dysphagia than the single treatments.

Evaluation of the Efficacy of Transcutaneous Electrical Acupoint Stimulation during the Treatment of Painless Colonoscopy

Objective:To investigate the clinical efficacy of transcutaneous electrical acupoint stimulation combined with propofol infusion during the treatment of patients under colonoscopy.Methods:A total of 90 patients received painless colonoscopy were randomly divided into three groups:transcutaneous electrical acupoint stimulation combined with propofol group(group T),sufentanil combined with propofol group(group S)and propofol group(group P),with 30 cases in each group.The patients in group T were anesthetized with propofol after transcutaneous electrical acupoint stimulation of 30min at Hegu(LI4),Neiguan(PC6),Zusanli(ST36),Shangjuxu(ST37)and Sanyinjiao(SP6)on both sides,and the electrical stimulation lasted until the end of the operation.Group S and group P were pasted electrode slices at the same acupoint with group T,but no electrical stimulation was given.The other treatments were the same as those in group T.Group S was given sufentanil 0.1ug/kg at the beginning of anesthesia.The levels of blood pressure(MAP),heart rate(HR)and pulse oxygen saturation(SpO2)were continuously monitored at time points of entering operating room(T0),disappearance of eyelash reflex(T1),during operation(through the liver region T2)and immediately after operation(T3),and the total dosage of propofol,awakening time and incidence of adverse reactions in each group were recorded.Results:Compared with group P,the blood pressure and heart rate of the patients at T1 and T2 in group T were more stable(P<0.05),the awakening time after operation was significantly shorter(P<0.05),and the dosage of propofol was significantly lower than that in group P(P<0.05).The incidence of bradycardia,hypotension and respiratory depression decreased significantly(P<0.05).Compared with group S,the postoperative awakening time of group T was significantly shorter(P<0.05),and there was no significant difference in other indexes.Conclusion:Transcutaneous electrical acupoint stimulation is effective during the treatment of analgesia under colonoscopy.It can reduce the dosage of anesthetics,reduce the incidence of postoperative adverse reactions and shorten the awakening time of patients.

Transcutaneous acupoint electrical stimulation(TAES)for pre-operative anxiety:a prospective observational pilot investigation

Objective:Transcutaneous acupoint electrical stimulation(TAES)treatment is effective for post-operative anxiety.The investigation was designed to study the feasibility and effectiveness of TAES treatment for pre-operative anxiety.Methods:62 volunteered surgical patients were included in the pilot investigation.They all received TAES treatment for 30 minutes in the evening of the day before operation.Hegu(LI4)and Neiguan(PC6)of both sides were selected as the treatment acupoints.The anxiety degrees were measured by State-Trait Anxiety Inventory.Heart rate and blood pressure were also recorded.Results:After TAES,pre-operative anxiety measured by State-Trait Anxiety Inventory dropped by almost 12%,and both heart rate and systolic blood pressure decreased significantly.Conclusion:The pilot investigation of TAES for pre-operative anxiety can successfully test the feasibility of outcome measurements and provide necessary data for calculating the sample size of a subsequent randomized controlled trial.

Effect of Unilateral Low-Frequency Stimulation of Hippocampus on Rapid Kindling—Induced Seizure Development in Rats

Since the last decade deep brain stimulation has been proposed as an alternative treatment for patients who do not become seizure-free with the current pharmacological treatments and cannot undergo resective surgical procedure. However, the optimal stimulation parameters remain undetermined and active research in humans and animals is necessary. The present study was designed to investigate the effect of unilateral Low Frequency Stimulation (LFS) of hippocampus on seizure development by using the hippocampal rapid kindling method (hRK) in rats. We used male Wistar rats implanted with electrodes in the ventral hippocampus. All rats underwent hRK (biphasic square wave pulses, 20 Hz for 10 seconds) during three consecutive days (twelve stimulations per day). The control group (hRK;n = 6) received only RK stimulus, while the treated group (LFS-hRK;n = 8) received also LFS (biphasic square wave pulses, 1 Hz for 30 seconds) immediately before the RK stimulus, during three consecutive days. At the end of behavioral testing on day 3, 62% (P < 0.05) of the animals receiving LFS treatment were still not fully kindled staying in stages 0-III (P < 0.01). The number of stimulations needed to achieve generalized seizures (stage IV-V of Racine scale) was significantly higher (P < 0.05) in the LFS group with respect to control group. No significant differences in the cumulative daily afterdischarge duration were observed between both groups. These findings suggest that preemptive LFS can significantly decrease the incidence of hippocampus-kindled seizures and delay the progression and secondary generalization of focal seizures.

Transcutaneous electrical acupoint stimulation benefits postoperative pain relief of oocyte retrieval:A randomized controlled trial

Background Transvaginal oocyte retrieval is frequently followed by adverse events related to anesthesia and the procedure.Some research showed that transcutaneous electrical acupoint stimulation(TEAS)can relieve intraoperative pain and postoperative nausea.Objective This study examined whether TEAS can alleviate pain and relieve adverse symptoms after oocyte retrieval.Design,setting,participants and interventions Altogether 128 patients were randomly divided into the TEAS group and the mock TEAS group.The two groups received a 30-minute-long TEAS or mock TEAS treatment that began 30 min after oocyte retrieval.Main outcome measures The primary outcome was the visual analog scale(VAS)pain score.Secondary outcomes were pressure pain threshold,McGill score,pain rating index(PRI),present pain intensity(PPI),VAS stress score,VAS anxiety score,and postoperative adverse symptoms.Results The baseline characteristics of the two groups were comparable(P>0.05).The VAS pain scores of the TEAS group were lower than those of the mock TEAS group at 60 and 90 min after oocyte retrieval(P<0.05).The McGill score,PRI and PPI in the TEAS group were significantly lower than those in the control group at 60 min after oocyte retrieval(P<0.05).However,the two groups had equivalent beneficial effects regarding the negative emotions,such as nervousness and anxiety(P>0.05).The TEAS group was superior to the mock TEAS group for relieving postoperative adverse symptoms(P<0.05).Conclusion TEAS treatment can relieve postoperative pain and postoperative adverse symptoms for patients undergoing oocyte retrieval.

Transcutaneous Electrical Acupoint Stimulation Combined with Warm Acupuncture for Breast Cancer Related Upper Limb Lymphedema:A Retrospective Cohort Study

Objective To observe the clinical efficacy of transcutaneous electrical acupoint stimulation(TEAS)combined with warm acupuncture in treating breast cancer associated with upper limb lymphedema(BCRL).Methods This was a retrospective cohort study using a paired control design.Fifty-two BCRL patients were assigned to the control group(27 cases)and the treatment group(25 cases).The patients in the control group were treated with lymphedema comprehensive detumescence treatment(CDT)for 4 weeks,including systematic therapy composed of manual lymphatic drainage,compression bandage,skincare,and functional exercise.The patients in the treatment group were treated with TEAS combined with warm acupuncture based on the control group methods.Each treatment lasted for 30 min and was applied twice a week for 4 weeks.The arm circumference(AC)of different positions of the affected limb and the degree of swelling of the affected limb were evaluated before the first treatment and after the last treatment.The clinical efficacy was evaluated according to the degree of edema before and after treatment.All adverse events during treatment were recorded.Results The patients’AC and the swelling feeling of the affected limb in the treatment group and the control group were both reduced compared with those before treatment.Compared with the control group,AC of the wrist joint transverse stria,the midpoint between the wrist joint transverse stria and the elbow joint transverse stria in the treatment group were significantly reduced(P<0.05).The decrease in AC diameter at the midpoint between the elbow joint transverse stria and the axillary transverse stria was the most significant(P<0.01).The swelling degree of the affected limbs in the treatment group was significantly lower than before treatment,and was significantly lower compared with the control group after treatment(P<0.01).The total effective rate was 72%in the treatment group,significantly higher than that in the control group(55.56%,P<0.05).No serious adverse events occured in either group.Conclusions TEAS combined with warm acupuncture can effectively reduce AC and swelling feeling of the affected limb in patients with BCRL.The effect is better than that of CDT therapy alone.

Transcutaneous Electrical Nerve Stimulation on Acupoints Relieves Labor Pain:A Non-randomized Controlled Study

Objective：To investigate the efficacy of transcutaneous electrical nerve stimulation（TENS）on four specific acupuncture points Hegu（LI4）,Neiguan（PC6）,Danshu（BL19）and Weishu（BL21）for reducing pain in labor.Methods：A total of 160 voluntary nulliparous women who were willing to receive TENS for analgesia were assigned to the treatment group after cervical dilation of more than 2 cm.Another 145 matched nullipara were recruited as the control group.Visual analogue scale（VAS）was used to assess the pain before and 0.5 h after the application of TENS.Then,VAS was assessed every one hour until delivery.Percentage of VAS score decreased by〉25%was the primary outcome,the delivery mode and neonatal outcome were measured as secondary outcomes.Adverse reactions were also recorded during TENS.Results：The percentage of VAS score decreased by〉25%was 68.6%in the TENS treatment group.Maternal delivery mode and neonatal outcomes were not significantly different between the two groups.In addition,the incidence of postpartum hemorrhage in the TENS treatment group was less than the control group（P〈0.05）.There was no adverse reaction recorded with TENS on acupoints.Conclusion：As a novel and non-invasive approach,TENS on specific acupoints including Hegu（LI4）,Neiguan（PC6）,Danshu（BL19）and Weishu（BL21）was an effective method for analgesia in labor.

Hippocampal High-Frequency Stimulation Inhibites the Progression of Rapid Kindling-Induced Seizure in Rats

Epilepsy is one of the most common serious neurological disorders. Pharmacoresistant epilepsy patients are poorly controlled or their seizures are refractory to drug treatment. Resective surgery is frequently a promising therapy in this population, however, not all the patients meet the eligibility criteria for the surgical treatment. Deep brain stimulation has been investigated in clinical studies and animal studies as an alternative treatment, but the optimal stimulation parameters remain an issue. The present study was designed to investigate the effect of unilateral high-frequency stimulation (HFS) of hippocampus on seizure development by using the hippocampal rapid kindling method (hRK) in rats, and compared the results with those of low-frequency stimulation previously published by our group. We used male Wistar rats implanted with electrodes in the ventral hippocampus. All rats underwent hRK (biphasic square wave pulses, 20 Hz for 10 seconds) during three consecutive days (twelve stimulations per day). The control group (hRK;n = 7) received only RK stimulus, while the treated group (HFS-hRK;n = 9) received also HFS (biphasic square wave pulses, 130 Hz for 30 seconds) immediately before the RK stimulus, during three consecutive days. At the end of behavioral testing 78% (p 0.01) of the animals receiving HFS treatment were still not fully kindled staying in stages 0 -III (p 0.01). HFS group needed a higher number of stimulations to achieve stage III (p 0.05) with respect to control group. However, no significant differences in the cumulative daily afterdischarge duration were observed. HFS did not present significant differences compared with LFS in any of studied parameters. The findings suggest that unilateral HFS applied on hippocampus effectively inhibited the epileptogenic process induced by hippocampal rapid kindling. According to the comparative results about hippocampal rapid kindled animals stimulated with HFS and LFS (5 Hz), we found no conclusive information on which treatment is most efficient.

厚朴排气合剂联合经皮穴位电刺激对产后抑郁合并胃肠功能障碍患者胃肠功能及抑郁情绪的影响

目的:探讨厚朴排气合剂联合经皮穴位电刺激对产后抑郁合并胃肠功能障碍的临床效果。方法:将120例产后抑郁合并胃肠功能障碍患者随机分为观察组(n=60)和对照组(n=60)。对照组给予经皮穴位电刺激治疗,观察组给予厚朴排气合剂联合经皮穴位电刺激治疗,疗程均为7 d。比较两组患者胃肠功能恢复情况、胃肠道障碍症状评分、胃泌素(GAS)、胃动素(MTI)、腹胀发生率、腹胀程度、汉密尔顿抑郁量表评分以及不良反应发生情况。结果:与对照组相比,观察组患者的肠鸣音恢复、首次肛门排气、首次排便、总住院时间明显更短(P<0.05)。治疗后,两组患者胃肠道障碍症状评分均明显下降,观察组低于对照组(P<0.05)。治疗后,两组患者GAS、MTI水平和治疗前相比均明显升高,且观察组高于对照组(P<0.05)。治疗后,观察组患者腹胀发生率为11.7%,低于对照组的30.0%(P<0.05)。治疗后,观察组患者腹胀程度明显低于对照组(P<0.05)。治疗后,两组患者抑郁状态评分均明显下降,观察组低于对照组(P<0.05)。两组不良反应发生率(6.7%与5.0%)比较差异无统计学意义(P>0.05)。结论:厚朴排气合剂联合经皮穴位电刺激可有效促进产后抑郁合并胃肠功能障碍患者胃肠功能恢复,缓解腹胀和抑郁情绪,而且不会明显增加不良反应发生率。

经皮穴位电刺激对老年肝癌患者术后早期认知功能障碍及血清相关炎症因子的影响

目的 探讨经皮穴位电刺激(TEAS)对老年肝癌患者术后早期认知功能障碍(POCD)及血清相关炎症因子的影响。方法 选取本院收治的行手术治疗的100例肝癌患者,使用随机数字表法分为两组(各50例),TEAS组从麻醉前开始至术毕始终给予TEAS,对照组不进行电流刺激。记录围术期指标、术后疼痛程度、POCD发生情况,并比较两组手术前后的血清S-100β蛋白(S-100β)、神经元特异性烯醇化酶(NSE)、白细胞介素-6(IL-6)及肿瘤坏死因子-α(TNF-α)水平变化。结果 两组的围术期指标及术后24 h VAS评分接近(P>0.05)。与对照组相比,TEAS组的丙泊酚用量、瑞芬太尼用量均明显更少(P<0.05)。与术前1 d相比,两组术后1、3、7 d MMSE评分更低,且组间对比显示TEAS组的MMSE评分更高(P<0.05)。TEAS组的POCD总发生率(24.00%)明显比对照组(68.00%)更低(P<0.05)。与术前1 d相比,两组患者术后1 d的血清S-100β、NSE、IL-6及TNF-α水平均显著升高(P<0.05),且TEAS组术后1 d的血清S-100β、NSE、IL-6及TNF-α水平较对照组更低。TEAS组术后的不良反应总发生率显著低于对照组(P<0.05)。结论 在老年肝癌患者术中行TEAS治疗可发挥镇痛作用,同时还能降低炎症因子水平,减轻脑损伤,降低POCD的发生风险,有利于患者的术后康复。
