Effects of electroacupuncture on recent stroke inpatients with incomplete bladder emptying: a preliminary study

A case report: Intermittent catheterization combined with rehabilitation in the treatment of carbapenem-resistant Klebsiella pneumoniae catheter-associated urinary tract infection

Catheter-related urinary tract infections, especially those caused by multidrug-resistant (MDR) bacteria, are extremely difficult to treat due to limited therapeutic choices. Therefore, removing catheters as soon as possible is pivotal to successful treatment. Herein, we report a case of catheter-related urinary tract infection caused by carbapenem-resistant Klebsiella pneumoniae (CRKP). Intermittent catheterization was used to reduce biofilm occurrence and exercise bladder function on the basis of an active and adequate anti-infection strategy. Simultaneously, combined with acupuncture treatment and strengthening the patient’s pelvic floor muscle training to improve urinary retention, the catheter was eventually removed to obtain autonomous urination in this patient, and this led to the successful treatment for a CRKP catheter-related urinary tract infection.

Efficacy of Acupuncture Treatment for Incidence of Poststroke Comorbidities: A Systematic Review and Meta-Analysis of Nationalized Cohort Studies

Acupuncture has been applied as a complementary therapy in stroke survivors worldwide and approved to be beneficial to stroke recovery. However, there is little medical evidence regarding the association between acupuncture and the risk of poststroke comorbidities. We reviewed big data studies from the Taiwan National Health Insurance Research Database to investigate the risk of poststroke comorbidities after acupuncture treatment in a real-world situation. Ten English (PubMed, Embase, Medline, Cochrane, Alt HealthWatch, CINAHL, Health Source, PsycINFO, PsycARTICLES, and Psychology and Behavioral Sciences Collection) and two Chinese (AiritiLibray and Visualizing Health Data) electronic databases were searched from inception until December 2020 for nationalized cohort studies comparing the effects of acupuncture treatment with a nonacupuncture control group among stroke patients. Eight nationalized cohort studies were included. Six of eight studies showed a moderate overall risk of bias, while two studies showed a serious overall risk of bias. Included studies have investigated the effect of acupuncture in reducing the risk of seven medical conditions after stroke, including stroke recurrence, new-onset acute myocardial infarction (AMI), pneumonia, dementia, epilepsy, urinary tract infection (UTI), and depression. The meta-analysis showed clinically significant reductions in the risk of poststroke comorbidities in the acupuncture group compared to the nonacupuncture group (HR, 0.776; 95% CI, 0.719–0.838; p < 0.0001). In this systematic review and meta-analysis of nationalized cohort studies, acupuncture showed clinically relevant benefits in reducing the incidence of poststroke comorbidities, such as stroke recurrence, new-onset acute myocardial infarction (AMI), pneumonia, dementia, epilepsy, and UTI.

Acupoint Injection Decreases Anesthetic Cosumption during Combined Spinal-Epidural and Patient-Controlled Epidural Labor Analgesia

OBJECTIVE

To explore if acupoint injection can improve analgesic effects or delivery outcomes in parturients who received combined spinal-epidural analgesia (CSEA) and patient-controlled epidural analgesia (PCEA) for labor analgesia.

METHODS

A total of 307 participants were prospectively collected from July 2017 to December 2019. The participants were randomized into the combined acupoint injection with CSEA plus PCEA group (AICP group, n=168) and CSEA plus PCEA group (CP group, n=139) for labor analgesia using a random number table. Both groups received CSEA plus PCEA at cervical dilation 3 cm during labor process, and parturients of the AICP group were implemented acupoint injection for which bilateral acupoint of Zusanli (ST 36) and Sanyinjiao (SP 6) were selected in addition. The primary outcome was Visual Analogue Scale (VAS) score, and the secondary outcomes were obstetric outcomes and requirement of anesthetics doses. Safety evaluations were performed after intervention.

RESULTS

The VAS scores were significantly lower in the AICP group than in the CP group at 10, 30, 60, and 120 min after labor analgesia (all P<0.05). The latent phase of the AICP group was shorter than that of the CP group (P<0.05). There were less additional anesthetics consumption, lower incidences of uterine atony, fever, pruritus and urinary retention in the AICP group than those in the CP group (all P<0.05).

CONCLUSION

Acupoint injection combined CSEA plus PCEA for labor analgesia can decrease the anesthetic consumption, improve analgesic quality, and reduce adverse reactions in the parturients. (Registration No. ChiMCTR-2000003120).

The Therapeutic Effect of Electroacupuncture Therapy for Ischemic Stroke

Electroacupuncture (EA) stimulation is a supplementary therapy and commonly applied in treatment of ischemic stroke in clinic. Stroke is an important cause of long-term disability in individuals in both developing and developed countries. In our review, we show the application of EA stimulation for apoplectic pain, limbs spasticity, blood flow interruption, depression, swallowing dysfunction, aphasia, urinary incontinence, cognition and memory impairment, and constipation following stroke in patients and the related mechanisms in animals. The effectiveness of EA involves with acupoints, intensity, intervals, and duration of intervention for treatment of stroke. The combination of EA and common rehabilitation treatment may exert better effect compared with EA alone. In summary, EA might provide a potential treatment strategy for treating apoplectic patients in clinic.

A randomized controlled trial of neuromuscular electrical stimulation for chronic urinary retention following traumatic brain injury

BACKGROUND

This study aimed to evaluate the effectiveness of neuromuscular electrical stimulation (NMES) therapy for chronic urinary retention (CUR) following traumatic brain injury (TBI).

METHODS

This 2-arm randomized controlled trial (RCT) enrolled 86 eligible patients with CUR following TBI. All included patients were randomly allocated to a treatment group (n = 43) or a sham group (n = 43). The administration of NMES or sham NMES, as intervention, was performed for an 8-week period treatment, and 4-week period follow-up. In addition, all subjects were required to undergo indwelling urinary catheter throughout the study period. The primary outcome was assessed by the post-voiding residual urine volume (PV-VRU). The secondary outcomes were evaluated by the voided volume, maximum urinary flow rate (Qmax), and quality of life, as assessed by Barthel Index (BI) scale. In addition, adverse events were also recorded during the study period. All primary and secondary outcomes were measured at baseline, at the end of 8-week treatment, and 4-week follow-up.

RESULTS

At the end of 8-week treatment, the patients in the treatment group did not achieve better outcomes in PV-VRU (P = .66), voided volume (P = .59), Qmax (P = .53), and BI scores (P = .67), than patients in the control group. At the end of 4-week follow-up, there were also no significant differences regarding the PV-VRU (P = .42), voided volume (P = .71), Qmax (P = .24), and BI scores (P = .75) between 2 groups. No adverse events occurred in either group.

CONCLUSIONS

In summary, the findings of this study showed that NMES therapy may not benefit patients with CUR following TBI.

Effects of electroacupuncture at BL33 on detrusor smooth muscle activity in a rat model of urinary retention

Background

Detrusor smooth muscle (DSM) underactivity may lead to urinary retention (UR). Electroacupuncture (EA) at BL33 may be effective in improving DSM contractions.

Objectives

This study aimed to investigate: (1) the effect of EA at BL33; and (2) the effect of different manipulation methods at BL33 on the modulation of DSM contractions in UR rats.

Methods

30 male Sprague-Dawley rats were anaesthetised with urethane and modelled by urethral outlet obstruction. First, 2 Hz EA at BL33, SP6 and LI4 wasrandomly applied to the UR rats for 5 min to observe the immediate effects (n=10); second, manual acupuncture (MA) (n=10) and 100 Hz EA (n=10) were applied with the same programme. DSM electromyography (EMG) and cystometrogram data were evaluated.

Results

(1) 2 Hz EA at BL33 and SP6 significantly increased DSM discharging frequency (0.80±0.10 Hz, P<0.001, and 0.22±0.14 Hz, P=0.038), shortened micturation intervals (65.67±20.65 s, P=0.008, and 35.62±15.84 s, P=0.042), prolonged the duration of voiding (2.13±0.61 s, P=0.005, and 0.47±0.16 s, P=0.015), and reduced residual pressure (−0.91±0.31 mmHg, P=0.019, and −0.66±0.27 mmHg, P=0.046). EA at LI4 was not associated with any functional effects (P>0.05). Compared with SP6, EA at BL33 had greater positive effects on DSM discharging frequency, duration of discharging, and duration of voiding (all P<0.05). (2) No statistically significant differences were shown between MA, 2 Hz EA and 100 Hz EA interventions when stimulating at BL33, SP6 or LI4.

Conclusions

EA at BL33 improved DSM contractions to a greater degree than EA at SP6 or LI4. There were no differences in effect when stimulating using 2 Hz EA, 100 Hz EA and MA.

Electroacupuncture versus sham electroacupuncture for urinary retention in poststroke patients: study protocol for a multicenter, randomized controlled trial

BACKGROUND

This study protocol evaluates the effectiveness of adjuvant electroacupuncture (EA) for urinary retention in poststroke patients undergoing conventional treatments, in comparison with that of a sham control.

METHODS/DESIGN

A multicenter, blinded, randomized controlled trial will be conducted in three hospitals in the Republic of Korea. We are recruiting 54 stroke survivors (aged >19 years), who were diagnosed with urinary retention based on the results of two consecutive post-void residual (PVR) tests, and dividing them randomly into two arms: the EA and Park-sham control groups. They will receive ten sessions of EA or sham treatment for 2 weeks. The participants will be blinded with non-penetrating needles and fake sounds of EA stimulators. The daily PVR ratio will be primarily measured at baseline and at the end of the study to statistically test the effectiveness of EA for poststroke urinary retention. Then, the Korean version of the Qualiveen Questionnaire, the Korean version of the International Prostate Symptom Score, and the blinding index will be assessed. After each EA session or sham EA, adverse events will be reported to evaluate the safety of EA. Results will be analyzed by using the independent t-test or Mann-Whitney U test, based on both intention-to-treat and per-protocol principles.

DISCUSSION

The findings will provide clinical evidence for the effectiveness of EA treatment to improve urinary retention in stroke survivors.

TRIAL REGISTRATION

This study protocol was registered in ClinicalTrials.gov (NCT02472288) on 10 June 2015.

Electroacupuncture at Dazhui (GV14) and Mingmen (GV4) protects against spinal cord injury: the role of the Wnt/β-catenin signaling pathway

Electroacupuncture at Dazhui (GV14) and Mingmen (GV4) on the Governor Vessel has been shown to exhibit curative effects on spinal cord injury; however, the underlying mechanism remains poorly understood. In this study, we established rat models of spinal cord injury using a modified Allen's weight-drop method. Ninety-nine male Sprague-Dawley rats were randomly divided into three equal groups: sham (only laminectomy), SCI (induction of spinal cord injury at T₁₀), and EA (induction of spinal cord injury at T₁₀ and electroacupuncture intervention at GV14 and GV4 for 20 minutes once a day). Rats in the SCI and EA groups were further randomly divided into the following subgroups: 1-day (n = 11), 7-day (n = 11), and 14-day (n = 11). At 1, 7, and 14 days after electroacupuncture treatment, the Basso, Beattie and Bresnahan locomotor rating scale showed obvious improvement in rat hind limb locomotor function, hematoxylin-eosin staining showed that the histological change of injured spinal cord tissue was obviously alleviated, and immunohistochemistry and western blot analysis showed that Wnt1, Wnt3a, β-catenin immunoreactivity and protein expression in the injured spinal cord tissue were greatly increased compared with the sham and SCI groups. These findings suggest that electroacupuncture at GV14 and GV4 upregulates Wnt1, Wnt3a, and β-catenin expression in the Wnt/β-catenin signaling pathway, exhibiting neuroprotective effects against spinal cord injury.

Electroacupuncture Treatment Improves Learning-Memory Ability and Brain Glucose Metabolism in a Mouse Model of Alzheimer's Disease: Using Morris Water Maze and Micro-PET

Introduction. Alzheimer's disease (AD) causes progressive hippocampus dysfunctions leading to the impairment of learning and memory ability and low level of uptake rate of glucose in hippocampus. What is more, there is no effective treatment for AD. In this study, we evaluated the beneficial and protective effects of electroacupuncture in senescence-accelerated mouse prone 8 (SAMP8). Method. In the electroacupuncture paradigm, electroacupuncture treatment was performed once a day for 15 days on 7.5-month-old SAMP8 male mice. In the normal control paradigm and AD control group, 7.5-month-old SAMR1 male mice and SAMP8 male mice were grabbed and bandaged while electroacupuncture group therapy, in order to ensure the same treatment conditions, once a day, 15 days. Results. From the Morris water maze (MWM) test, we found that the treatment of electroacupuncture can improve the spatial learning and memory ability of SAMP8 mouse, and from the micro-PET test, we proved that after the electroacupuncture treatment the level of uptake rate of glucose in hippocampus was higher than normal control group. Conclusion. These results suggest that the treatment of electroacupuncture may provide a viable treatment option for AD.

Selection of acupoints for managing upper-extremity spasticity in chronic stroke patients

BACKGROUND

This study investigated the clinical efficacy of electroacupuncture (EA) in inhibiting upper-extremity spasticity in chronic stroke patients, and also in mapping a unique preliminary acupoint-selection protocol.

METHODS

Fifteen patients were divided into two groups: patients in the control group (n=6) received minimal acupuncture (MA), and those in the experimental group (n=9) received EA. Four acupoints, which include Neiguan (PC6), Shaohai (HT3), Zeqian (Ex-UE, A32), and Shounizhu (EX-UE), were treated near the motor points of the muscles for elbow flexion, forearm pronation, and finger flexion. Both groups were treated for twelve sessions, 20 minutes per session, for 6 weeks (two sessions per week). The outcome measures in this study included angle of muscle reaction (R1), passive range of motion (R2), and dynamic component (R2-R1).

RESULTS

In the experimental group, the R2-R1 of the elbow joint was significantly decreased at 1 (P=0.0079), 3 (P=0.0013), and 6 weeks (P=0.0149) after treatment compared with pretreatment levels (P<0.05). The between-group difference in the R2-R1 of the elbow joint after the 6-week treatment was statistically significant.

CONCLUSION

Combining the 6-week EA and standard rehabilitation treatment reduced the spasticity of the elbow for chronic stroke survivors. However, no significant effect was observed in the spasticity of the wrist joints. The choice of acupoints and the frequency of EA have to be taken into account to achieve a positive treatment effect. The correlation between acupoints and motor points provides a model of acupoint selection to improve spasticity.
