Atopic eczema (AE) is a chronic relapsing dermatological disease characterized by pruritus, dryness, erythema, and lichenification. Acupuncture as an alternative treatment can relieve symptoms, reduce the recurrence, and improve the quality of life (QoL) with less adverse reactions in treating AE. This network meta-analysis (NMA) will comprehensively access the efficacy and safety of different acupuncture therapies for patients with AE, and rank the different acupuncture therapies, in order to present evidence-based medicine evidence for clinical application extensively.This study will search 8 electronic databases from the establishment of the database to August 30th, 2022. The screening of literature, data extraction, and risk of bias assessment will be conducted by 2 researchers, respectively. The quality of evidence will be judged by the Grading of Recommendations Assessment, Development and Evaluation system. This NMA will be analyzed with Stata Version. 14.0 and WinBUGS Version.1.4.3.This study will comprehensively access the efficacy and safety of different acupuncture therapies for patients with AE on the severity, itch intensity, emotional symptoms, QoL, and recurrence rate. Moreover, it will further identify which acupuncture therapy is the most effective.The findings of this NMA may help patients and therapists choose the best acupuncture therapy in treating AE and furnish reliable evidence for guidelines.PROSPERO CRD42020203437.

Background: Plantar heel pain syndrome (PHPS), also known as plantar fasciitis, affects millions of people worldwide. Electroacupuncture (EA) and manual acupuncture (MA) are the two acupuncture modalities frequently used for PHPS in the clinical setting. However, which modality is more effective has yet to be determined. Objective: To examine whether EA is more effective than MA with regards to pain relief for patients with PHPS. Methods: Participants were randomly assigned (1:1) to receive 12 treatment sessions of EA or MA over 4 weeks with 24 weeks of follow-up. The primary outcome was the proportion of treatment responders, defined as patients with at least a 50% reduction from baseline in the worst pain intensity experienced during the first steps in the morning after a 4-week treatment, measured using a visual analogue scale (VAS, 0–100; higher scores signify worse pain). Analysis was by intention-to-treat. Results: Ninety-two patients with a clinical diagnosis of PHPS were enrolled from 29 July 2018 through 28 June 2019. Of the patients, 78 (85%) completed the treatment and follow-up. The primary outcome occurred in 54.8% (23/42) of the EA group compared to 50.0% (21/42) of the MA group after the 4-week treatment (difference –4.76, 95% confidence interval, –26.10 to 16.57, P = 0.662). There were no significant between-group differences for any secondary outcomes after 4 weeks of treatment and at 16 weeks and 28 weeks of follow-up. There were no serious treatment-related adverse events in either group. Conclusion: Among patients with PHPS, EA did not have a better effect with respect to relieving pain intensity than MA at week 4, although both EA and MA appeared to have positive temporal effects, with decreased heel pain and improved plantar function.

Objective: The aim of this study was to examine the effectiveness of acupuncture in treating the symptoms and quality of life (QoL) of patients with moderate or severe acne vulgaris (AV). Methods: Participants were randomly assigned (1:1) to receive 12 treatment sessions of acupuncture or sham acupuncture over 4 weeks with 24 weeks of follow-up. The primary outcome was the change from baseline in the Skindex-16 scale total score at treatment completion. Secondary outcomes included Skindex-16 subscale score, Dermatology Life Quality Index scale total score, total lesion count and inflammatory lesion count, and visual analogue scale scores for itch and pain evaluation. Results: There was no statistically significant between-group difference for the primary outcome or any secondary outcomes after 4 weeks of treatment and at 16 and 28 weeks of follow-up, except for the Skindex-16 emotions subscale at week 4 (p = 0.026). No serious adverse events occurred in either group. Conclusion: Acupuncture may not effectively relieve the symptoms of patients with moderate or severe AV, or improve QoL. Given the limitations of a relatively short treatment course compared to other studies and the likelihood that sham acupuncture is not inert, further studies with treatment durations of 12 weeks or longer and a waitlist (no treatment) control or Western medicine-treated control group should be considered to evaluate the effects of acupuncture on AV.

With the rapid development of electronic devices and rubber tires, the industry has put forward new requirements for the heat dissipation of rubber components. With excellent thermal conductivity, oxidation resistance, and thermal stability, hexagonal boron nitride (h-BN) is often added to plastics or rubber as a thermally conductive filler, but is less effective when used directly. In this study, h-BN-K was prepared by direct modification of the mixed solution of KH-550, and KH-570, while h-BN-PK was prepared by co-modification of dopamine, KH-550, and KH-570. Two modified h-BN were added to natural rubber (NR) to improve the vulcanization properties, mechanical properties, and thermal conductivity. It was found that the tensile strength and thermal conductivity of 20 wt% h-BN-PK/NR composites were 30.6 MPa and 0.335 W/mK, which were 39.1% and 110.7% higher compared to pure NR (22.0 MPa and 0.159 W/mK), respectively. In addition, the addition of h-BN improved the thermal stability performance of NR to some extent. In conclusion, the h-BN-PK/NR composites provide a certain reference for the use of thermally conductive NR and suggest new ideas for heat dissipation of electronic devices.

Objective: The aim of this study was to systematically assess the effectiveness and safety of acupuncture for patients with atopic eczema (AE). Methods: Two reviewers searched 13 databases from their inception through 31 July 2018 for randomized controlled trials (RCTs) of patients with AE. Dichotomous data and continuous data were analyzed using risk ratio (RR) and mean difference (MD), respectively, with 95% confidence intervals (CIs). Results: A total of eight RCTs (with 434 participants) were included. The results of one included RCT showed that acupuncture was better than no treatment at reducing itch intensity measured using a visual analogue scale in patients with AE. The combined results of six RCTs showed that acupuncture was better than conventional medicine at reducing the eczema area and severity index (EASI) (MD: −1.89, 95% CI: −3.04 to −0.75, I2: 78%) and the combined results of seven RCTs showed that acupuncture was better than conventional medicine in terms of global symptom improvement (RR: 1.59, 95% CI: 1.20 to 2.11, I2: 55%) in AE. We had insufficient data to show significant effects of acupuncture on quality of life and AE recurrence rate. No severe adverse events were found related to acupuncture. Limitations: The included RCTs had some methodological limitations, and most of the included trials were conducted in China. This analysis only included studies that compared acupuncture alone with no treatment or positive control (conventional medicine), so the specific effects of acupuncture could not be evaluated. Conclusion: Acupuncture might be effective at reducing itch intensity and may be more effective than conventional medicine at reducing EASI and improving the global symptoms of AE.

Background : Acne vulgaris (AV) is a common chronic dermatologic disease that tends to impair the appearance and the quality of life (QoL) of patients. Although several trials have indicated the effectiveness of acupuncture for treatment of patients with AV, the results of these trials have been contested owing to potential bias in their design. Thus, there is a lack of robust data to evaluate the efficacy of acupuncture in patients with AV. In addition, none of the previous clinical trials of acupuncture therapy for AV used QoL as a primary outcome or employed a sham acupuncture control arm. The aim of the study is to evaluate the effect of acupuncture on the symptoms and the QoL of patients with moderate or severe AV. Methods/design: One hundred eligible participants with AV will be randomly assigned to acupuncture or sham acupuncture groups (1:1 allocation). All participants will receive 4-week treatment comprising of a total of 12 sessions (3 sessions per week). The primary outcome will be change from baseline in the Skindex-16 scale total score at treatment completion. The secondary outcomes will be: Skindex-16 subscale score; the Dermatology Life Quality Index scale total score; the total lesion count and inflammatory lesion count; visual analogue scale scores for assessment of itch and pain; patient expectations of acupuncture; and the blinding of the effect of sham acupuncture. Follow-up evaluation will be performed at weeks 16 and 28. All outcome analyses will be performed in the intention-to-treat population. Discussion: We expect to evaluate the effectiveness of acupuncture in ameliorating the symptoms and improving the QoL of patients with moderate or severe AV compared with sham acupuncture with more robust evidence. The limitations of the trial design are its single center scope, relatively small sample size, and lack of blinding of the acupuncturists.

Background: Acne vulgaris (AV) is a common chronic dermatologic disease that tends to impair the appearance and quality of life (QoL) of patients. Although acupuncture has been indicated as an effective treatment for patients with AV in several trials, the results of these trials are also controversial due to potential for bias of their design. And none of the previous clinical trials of acupuncture therapy for AV used the QoL as a primary outcome or employed a sham acupuncture control arm. The aim of the study is to evaluate the effect of acupuncture on the symptoms and QoL of patients with moderate or severe AV. Methods/design: Ninety-six eligible participants with AV will be randomly assigned to acupuncture or sham acupuncture groups (1:1 allocation). All participants will receive 4-week treatment comprising of a total of 12 sessions (3 sessions per week). The primary outcome will be change from baseline in the Skindex-16 scale total score at treatment completion.

Follow-up evaluation will be performed at weeks 16 and 28. All outcome analyses will be performed in the intention-to-treat population. Discussion: We expect to evaluate the effectiveness of acupuncture on the symptoms and QoL of patients with moderate or severe AV compared with sham acupuncture. The limitation of the design of this trial is that the single center study with a relatively small sample size, the acupuncturists will not be blinded.

Background Acne vulgaris (AV) is a common chronic dermatologic disease that tends to impair the quality of life of patients. None of the previous clinical trials of acupuncture therapy for AV used the quality of life as a primary outcome or employed a sham acupuncture control arm. Methods/design Participants with AV will be randomly assigned to acupuncture or sham acupuncture groups (1:1 allocation). All participants will receive 4-week treatment comprising of a total of 12 sessions (3 sessions per week). The primary outcome will be change from baseline in the Skindex-16 scale total score at treatment completion. The secondary outcomes will be Skindex-16 subscale scores, the Dermatology Life Quality Index scale total score, the total lesion count and inflammatory lesion count, itch and pain assessment using the visual analogue scale score, patient expectations of acupuncture, patient satisfaction with treatment, and the blinding of the effect of sham acupuncture. Follow-up evaluation will be performed at weeks 16 and 28. All outcome analyses will be performed in the intention-to-treat population. Discussion This is the first randomized controlled trial which will compare the effect of acupuncture versus sham acupuncture in improving the quality of life of patients with moderate or severe acne vulgaris (AV). The limitation of the design of this trial is that the sample size of a single center trial, which may lead to potential overestimation of the effect of acupuncture. Meanwhile, due to the characteristics of acupuncture, the acupuncturists will not be blinded and the use of non-acupoints and minimal acupuncture without any manipulation, which may introduce an element of bias and cause some biological effect.

Chronic urinary retention (CUR) is defined as a non-painful bladder that remains palpable or percussible after the patient has passed urine. Acupuncture may decrease PVR and improve bladder function in patients with neurogenic CUR. The aim of this study was to preliminarily observe the effectiveness of electroacupuncture (EA) for patients with CUR caused by a lower motor neuron lesion and to provide some therapeutic data for further study.This study was a pilot study of 30 patients with CUR caused by a lower motor neuron lesion. Patients were treated with EA for 12 weeks with 36 sessions of EA.Responders were defined as participants with a decline in postvoid residual urine (PVR) volume after spontaneous urination of ≥50% from baseline. The proportion of responders, change in PVR volume from baseline after spontaneous urination, and the proportion of patients with severe difficulty with urination, who required assistance with bladder emptying and with stool retention, were measured at weeks 4, 8, and 12.Thirty patients were included in this study, and 23 completed 12 weeks of treatment. The proportion of responders at weeks 4, 8, and 12 was 6.67%, 28%, and 43.48%, respectively. Decrease in PVR volume, compared with baseline, was significant at all asessment timepoints. The proportion of patients with severe difficulty with urination, who required assistance with bladder emptying and with stool retention, decreased after treatment.EA is a potential treatment for improving bladder function in patients with CUR caused by a lower motor neuron lesion.

Background Pelvic organ prolapse (POP) is the downward descent of vaginal walls, affecting the health of 32% to 76% female patients. Conservative interventions are considered as priority before seeking help from surgery. We plan to make the systematic review to assess the effectiveness of conservative intervention for adult women with POP. Methods Studies will be searched in PubMed, EMBASE, and the Cochrane Library from inception to July 2017. Primary outcomes are specific POP-related symptom, severity of prolapse, Prolapse-related, and general health-related quality of life and other non-POP-specific symptoms. Results The data will be synthesized if possible using MD, SMD or RR. A descriptive analysis will be made if the data cannot be synthesized. Discussion The systematic review might provide solid evidence for the treatment of POP by conservative intervention.

Postmenopausal women are at a higher risk of stress urinary incontinence (SUI). In a previous trial, electroacupuncture (EA) was shown to be an effective treatment for women with SUI. Here we present a secondary analysis to investigate the specific factors associated with response to acupuncture therapy among postmenopausal women with SUI. We conducted secondary analysis of data from a multicenter randomized controlled trial. This trial included a baseline period of 1 week and a treatment period of 6 weeks with electroacupuncture (EA) or sham electroacupuncture (SA). The patients were randomly assigned to 2 groups (EA group or SA group). Participants who showed a decrease in urine leakage by at least 50% from baseline level, as measured by 1-hour pad at week 6, were defined as responders. Baseline characteristics associated with response to acupuncture therapy (e.g., demographic, comorbidities, and lifestyle-related factors) were identified by logistic regression analysis and the interactions between treatment assignment and baseline characteristics assessed. This analysis included a total of 349 postmenopausal women, of whom 137 (39.3%) were classified as responders. Response rate in the EA group was significantly higher than that in the SA group (60.9% vs 18.9%, respectively; P

IntroductionPlantar heel pain syndrome(PHPS) is a common cause of heel pain. It may worsen a patient’s quality of life, and potentially lead to knee, hip or lower back problems. Previous studies have shown that electroacupuncture (EA) and manual acupuncture (MA) are effective treatments for relieving pain in patients with PHPS. However, little evidence supports the use of one intervention over the other.Methods and analysisA total of 92 patients diagnosed with PHPS will be recruited and randomly assigned to an EA group or an MA group at a ratio of 1:1. Patients in both groups will receive a 30 min acupuncture treatment (three times per week) for a total of 12 sessions over 4 weeks. The primary outcome will be the proportion of patients with at least 50% reduction from baseline in the worst pain intensity measured by visual analogue scale (0–100, higher scores signify worse pain) at first steps in the morning after 4-week treatment. The secondary outcomes will include change in worst pain intensity at first steps in the morning, change in mean pain intensity at first steps in the morning, change in worst pain intensity during the day, change in mean pain intensity during the day, change in the pressure pain threshold, change in ankle-dorsiflexion range of motion, change in Foot and Ankle Ability Measure total score and subscale scores, patients’ global improvement assessment, patients’ expectations for acupuncture and safety evaluation. We will perform all statistical analysis following the intention-to-treat principle.Ethics and disseminationThe study has been approved by our ethics review board (Protocol Approval No. 2018–010-KY). The study findings will be disseminated through presentation at a high-impact medical journal, with online access. We also to plan to present it in select conferences and scientific meetings.Trial registrationChiCTR-1800016531; Pre-results.

Background: To treat functional constipation, both electroacupuncture (EA) therapy and transcutaneous electric nerve stimulation (TENS) are safe and effective. However, no head-to-head comparison trial has been conducted. This trial compares the efficacy of electroacupuncture relative to transcutaneous electric nerve stimulation for functional constipation. Methods: Individuals with functional constipation will be randomly allocated to receive either EA or TENS (n = 51, each), 3 times per week for 8 weeks. The primary outcome is the percentage of participants with an average increase from baseline of 1 or more complete spontaneous bowel movements at week 8. The secondary outcome measures are the following: at the time of visits, changes in the number of complete spontaneous bowel movements, number of spontaneous bowel movements, stool character, difficulty in defecation, patients’ assessment of quality of life regarding constipation (self-report questionnaire), and use of auxiliary defecation methods. Discussion: The results of this trial should verify whether EA is more efficacious than TENS for relieving symptoms of functional constipation. The major limitation of the study is the lack of blinding of the participants and acupuncturist.
