Fire-needle acupuncture for upper limb spastic paralysis after stroke: Study protocol for a randomized controlled trial

Fire acupuncture for anti-LGI1 antibody autoimmune encephalitis: a case report

Autoimmune encephalitis, a class of encephalitis, is clinically characterized by multifocal or diffuse brain injury, including aberrant mental behavior, convulsions, and near-event memory impairment. In this article, we describe a female patient with autoimmune encephalitis who tested positive for leucine-rich glioma inactivated 1 (LGI1) antibodies and had hippocampal inflammatory edema in the lesion area. During the first 3 months of her illness, the patient primarily experienced memory loss, the onset of rigid twitching in her extremities that lasted for 1 min while in remission, and incontinence. After gamma globulin administration, methylprednisolone shock, and other symptomatic therapies during hospitalization, the patient's psychiatric symptoms and seizures improved considerably; however, she did not fully recover her memory. After receiving fire acupuncture for 6 months, the patient's understanding, orientation, and calculation skills improved considerably. Her memory and mental state were also improved at the follow-up visit. In this case, the use of fire acupuncture for the treatment of autoimmune encephalitis resulted in favorable outcomes with important benefits for conditions affecting the central nervous system; however, more convincing data are required to support the effectiveness of this treatment method.

Filiform needle acupuncture for allergic rhinitis: A systematic review and meta-analysis

BACKGROUND

Filiform needle acupuncture (FNA), the most classical and widely applied acupuncture method based on traditional Chinese medicine theory, has shown a promising effect in the treatment of allergic rhinitis (AR).

OBJECTIVE

To evaluate the efficacy, safety, cost-effectiveness, and patient preference of FNA in the treatment of AR by comparing FNA with sham acupuncture, no treatment, and conventional medication.

SEARCH STRATEGY

Eight electronic databases were systematically searched from inception to October 14, 2021. Additional studies were acquired from clinical trial registration platforms and reference lists.

INCLUSION CRITERIA

Randomized controlled trials were included if they compared FNA with either sham acupuncture, no treatment or conventional medication for AR.

DATA EXTRACTION AND ANALYSIS

Two researchers extracted data independently of each other using a predesigned data acquisition form, and results were cross-checked after completion. The primary outcome was symptom score (Total Nasal Symptom Score or Visual Analogue Scale), and the secondary outcomes were the AR control questionnaire, quality of life (QoL) score (Different versions of Rhinoconjunctivitis Quality of Life Questionnaire), medication score (use of rescue medication), mental health score, total IgE, adverse event rate, clinical economic indicators, and patient satisfaction score. Standardized mean difference (SMD) or mean difference (MD) with 95% confidence interval was used to calculate the effect size for continuous data, while risk ratio with 95% CI was used for dichotomous data.

RESULTS

Thirty studies were included in this review. Compared with sham acupuncture, FNA significantly reduced the symptom score (SMD: -0.29 [-0.43, -0.15]), AR's impact on QoL (SMD: -0.23 [-0.37, -0.08]) and medication score (SMD: -0.3 [-0.49, -0.11]). Compared with no treatment, FNA dramatically reduced the symptom score (SMD: -0.8 [-1.2, -0.39]) and AR's impact on QoL (SMD: -0.82 [-1.13, -0.52]). There were no increased rates of adverse events with FNA compared to sham acupuncture and no treatment. FNA increased patient satisfaction and may be cost-effective. Most pieces of evidence from the above two comparisons were of high confidence. Moreover, FNA significantly outperformed conventional medication in reducing the symptom score (SMD: -0.48 [-0.85, -0.1]) and displayed a lower rate of adverse events, but the quality of evidence was very low.

CONCLUSION

FNA is an effective and safe intervention for AR and can help with symptom relief, QoL improvement, reducing medication usage, and increasing patient satisfaction. Further studies are needed to verify its cost-effectiveness and superiority over conventional medication and the best therapeutic strategies.

Analysis of the Efficacy of Acupuncture Combined with Rehabilitation Training in the Treatment of Upper Limb Spasm after Stroke: A Systematic Review and Meta-Analysis

Objective

Systematic evaluation of the efficacy of acupuncture combined with cognitive rehabilitation training in the treatment of upper limb spasm after cerebral apoplexy.

Methods

The data of CNKI, CBM, CQVIP, Wanfang, and the libraries of Pubmed and Cochrane were searched by computer, and the related literatures about acupuncture combined with cognitive rehabilitation training in the treatment of cognitive dysfunction after stroke were searched. The search time is from January 1, 1995 to January 1, 2022. All data segments were independently analyzed and extracted by two evaluators. After evaluating the quality of the methodology, meta-analysis was carried out by using the RevMan5.4 software.

Results

Finally, 11 studies were included, with a total of 789 subjects. The results of meta-analysis indicated that acupuncture combined with cognitive rehabilitation training was superior to simple cognitive rehabilitation training or drugs in the following aspects, the difference exhibited statistically significant, the total effective rate (RR = 1.58, 95% CI), latency of P300 (MD = -18.46, 95% CI), amplitude of P300 (MD = 1.23, 95% CI (0.82), P < 0.00001, 95% CI (0.31)), and activity of daily living (ADL), respectively, were significantly higher compared to the control group (P < 0.00001), and the difference was statistically significant (P < 0.05). Based on the results of systematic evaluation, the GRADE system recommendation classification method is used to evaluate the quality of evidence. The results show that the level of evidence is low and the intensity of recommendation is weak.

Conclusion

The results of this meta-analysis suggest that the curative effect of acupuncture combined with cognitive rehabilitation training is better compared to simple cognitive rehabilitation training or drugs. However, due to the low quality of the original literature, it needs to be confirmed by multicenter, high-quality, large-sample randomized blind controlled trials in the future.

Fire Acupuncture versus conventional acupuncture to treat spasticity after stroke: A systematic review and meta-analysis

BACKGROUND

Post-stroke spasm is currently a complex clinical problem that remains to be resolved. Due to its excellent efficacy and few side effects, clinicians have used fire acupuncture to treat post-stroke spasticity in China.

OBJECTIVES

The purpose of this study was to evaluate the clinical efficacy of fire acupuncture compared with conventional acupuncture to treat post-stroke spasms and provide a detailed summary of the commonly used acupoints.

METHODS

Eight databases (MEDLINE/PubMed, Web of Science, the Cochrane database, EMBASE, CBM, CNKI, WanFang, and VIP) were searched for randomized controlled trials (RCTs) published from database inception through August 30, 2020. RCTs that compared fire acupuncture with conventional acupuncture as a treatment intervention for patients with spasticity after stroke were included. Revman 5.3 software was used to calculate risk ratios (RR) and standard mean differences (SMD) with 95% confidence intervals (CI). Methodological evaluation or critical appraisal of the included articles was assessed using RoB-2.

RESULTS

Sixteen studies with a total of 1,118 patients were included. Although according to the standards of the Rob 2.0 tool, most studies are considered to have some problems. Comprehensive analysis of the results revealed a consistent trend indicating several advantages of using fire needles compared to conventional acupuncture in treating post-stroke spasms, including the effective rate, recovery rate, and improvement of multiple scales represented by MAS. Concerning secondary outcomes, using the scales of FMA, BI, or NDS in this random model meta-analysis, fire acupuncture exhibited better performance compared to acupuncture [SMD = 2.27, 95%CI [1.40,3.13 (random-effects model) ], [SMD = 1.46,95% CI [1.03,1.90 (random-effects model)], and [SMD = 0.90, 95%CI [0.44,1.35 (random-effects model)], respectively, with moderately high heterogeneity. When the effective rate was used as an outcome in the subgroup analysis, fire needles performed better than conventional acupuncture with respect to damage to the upper or lower limbs, and the thickness and depth of acupuncture. When the modified Ashworth scale (MAS) was used as the outcome, and the damage occurred in the lower extremity, the acupuncture depth exceeded 15mm, or the duration of stroke was longer than six months, the fire needles did not perform better than conventional acupuncture, [SMD = 0.01, 95%CI [-0.47,0.48 (fix-effects model)], [SMD = 0.21 [-0.51,0.93(random-effects model)], and [SMD = 0.76, 95%CI [-0.08,1.60 (random-effects model)], respectively. The acupoints identified with the highest frequencies in this study were Yang-meridian, including LI11-Quchi (nine times), LI4-Hegu (seven times), and ST36-Zusanli (five times). Moreover, no serious adverse effects were reported in any of the studies included in this analysis.

CONCLUSIONS

Despite several limitations, this was the first meta-analysis to focus on the treatment of post-stroke spasticity using fire needle acupuncture compared with conventional acupuncture. Our results confirmed that fire needles could provide a better clinical effect than conventional acupuncture, which will help standardize fire needle treatment strategies for post-stroke spasms.

Protective effect of microRNA‑340‑5p against oxygen‑glucose deprivation/reperfusion in PC12 cells through targeting neuronal differentiation 4

The expression levels of microRNA (miR)‑340‑5p are reportedly decreased in the peripheral blood during acute ischemic stroke; however, the direct effect and mechanism of action of miR‑340‑5p in ischemic stroke remains largely unknown. The present study aimed to investigate the effects of miR‑340‑5p, and its mechanism of action, on PC12 cells following oxygen‑glucose deprivation/reperfusion (OGD/R) induction. OGD/R‑induced PC12 cells served as the cellular model and subsequently, mRNA expression levels of miR‑340‑5p and neuronal differentiation 4 (Neurod4) were analyzed using reverse transcription‑quantitative PCR. Tumor necrosis factor‑α, interleukin (IL)‑1β and IL‑6 expression levels were detected using ELISA kits, and flow cytometry was used to determine the rate of cellular apoptosis. In addition, a nitric oxide (NO) synthase activity assay kit was used to detect NO levels and a NADPH assay kit was used to measure NADPH levels. Western blotting was also performed to analyze protein expression levels of bax, bcl‑2, cleaved caspase 3 and phosphorylated endothelial NOS (eNOS), and the target gene of miR‑340‑5p was predicted using TargetScan software and verified using a dual‑luciferase reporter assay. The expression levels of miR‑340‑5p were decreased in PC12 cells following OGD/R induction and Neurod4 was identified as a target gene of miR‑340‑5p. In addition, miR‑340‑5p overexpression reduced inflammation, apoptotic rate, NO production and NADPH levels, in addition to increasing eNOS expression in PC12 cells following OGD/R induction. Notably, the overexpression of Neurod4 reversed the aforementioned effects of miR‑340‑5p on PC12 cells following OGD/R induction. In conclusion, the findings of the present study suggested that miR‑340‑5p may protect PC12 cells against OGD/R through targeting Neurod4, which could provide important implications for the treatment of ischemia‑reperfusion injury based on miR‑340‑5p expression levels in vivo.

Acupuncture of fascia points to relieve hand spasm after stroke: a study protocol for a multicenter randomized controlled trial

Background

The loss of functional ability of patients after stroke is mostly caused by dysfunction of the upper limbs, especially the hands. Hand functional exercise is the premise of alleviating hand dysfunction, and the relief of hand spasm is the basis of timely and effective hand functional exercise. Previous clinical observation have shown that fascial-point needling can effectively alleviate hand spasm immediately after stroke, but further evidence from large-sample studies is needed. The overall objective of this trial is to further evaluate the clinical efficacy of fascial-point acupuncture on hand spasm after stroke.

Methods/design

This multicenter randomized controlled trial will compare the efficacy of fascial-point acupuncture versus sham acupuncture and routine rehabilitation therapy in stroke patients with hand spasm. Patients will be randomized to undergo either the fascial-point acupuncture, the sham acupuncture or the control (routine rehabilitation therapy). We will recruit 210 stroke inpatients who meet the trial criteria and observe the remission of hand spasm and improvement of limb function after 4 weeks of intervention. The first evaluation indices are the remission of hand spasm and the duration of spasm remission. The second evaluation indices are the hand function of the affected limbs and the activities of daily living. When the accumulative total number of cases included reaches 120, a mid-term analysis will be conducted to determine any evidence that experimental intervention does have an advantage.

Discussion

Our aim is to evaluate the efficacy of fascial-point acupuncture in relieving hand spasm after stroke. The results should provide more evidence for the clinical application of this therapy in the future.
