[Effect of electroacupuncture at different time points on postoperative urination function in patients with mixed hemorrhoids surgery].

OBJECTIVE: To observe the effect of preoperative, intraoperative and postoperative electroacupuncture (EA) intervention on postoperative urination function in patients with mixed hemorrhoid surgery. METHODS: A total of 240 patients with mixed hemorrhoid surgery under lumbar anesthesia were randomly divided into an EA preconditioning group (group A, 60 cases, 9 cases dropped off), an intraoperative EA group (group B, 60 cases, 4 cases dropped off), a postoperative EA group (group C, 60 cases, 6 cases dropped off), and a non-acupuncture group (group D, 60 cases, 3 cases dropped off). In the groups A, B and C, EA was exerted at Zhongliao (BL 33) and Huiyang (BL 35) , with disperse-dense wave, 4 Hz/20 Hz in frequency, and lasting 30 min, at 30 min before lumbar anesthesia, immediately after lumbar anesthesia and 6 h after surgery, respectively. No EA intervention was performed in the group D. The postoperative urination smoothness score in each group was observed 24 h after surgery. The first urination time, first urination volume, urine residual volume after first urination were recorded, and incidence of indwelling catheterization, postoperative visual analogue scale (VAS) score, number of remedial analgesia, and the incidence of postoperative nausea and vomiting were observed in each group. RESULTS: In the groups A, B and C, the postoperative urination smoothness scores were superior to the group D (P<0.05), and the time of first urination was earlier than the group D (P<0.05). In the group C, the time of first urination was earlier than the group A and the group B (P<0.05), the first urination volume was higher than the group D (P<0.05), and the urine residual volume after first urination was lower than the group D (P<0.05). There was no significant difference in the incidence of indwelling catheterization and postoperative nausea and vomiting among the 4 groups (P>0.05). The VAS scores of the group A, B and C were lower than that in the group D (P<0.05), and the number of remedial analgesia cases was lower than that in the group D (P<0.05). CONCLUSION: EA intervention could promote the recovery of urination function and relieve postoperative pain in patients with mixed hemorrhoids surgery. Early postoperative EA intervention is more conducive to the recovery of urination function.

Different Acupuncture Therapies for Allergic Rhinitis: Overview of Systematic Reviews and Network Meta-Analysis.

OBJECTIVE: To evaluate the quality of methodologies used in previous systematic reviews (SRs) and compare efficacy of different acupuncture therapies for allergic rhinitis. METHODS: Seven electronic databases were searched for systematic reviews (SRs) performed on different acupuncture therapies for allergic rhinitis from inception to 15 November 2019. The AMSTAR2 instrument was employed to assess the methodological quality of included SRs. Eligible randomized controlled trials (RCTs) were selected from the included systematic reviews. We also included recent RCTs published by 15 November 2019. Cochrane risk of bias tool was utilized to determine risk of bias of the included RCTs. Pairwise meta-analyses were performed using the random-effects model. Network meta-analysis of the included RCTs was carried out using frequentist framework. RESULTS: We identified 2 SRs with low quality and 18 SRs with very low quality, both of which contained 33 eligible RCTs (n = 3769). Most of these studies had unclear risk of bias. On the basis of ranking probability, NMA analysis showed that acupuncture at the sphenopalatine ganglion acupoint (OR: 1.31, 95% CI 1.07 to 1.61) had the highest probability of improving global allergic rhinitis symptoms, followed by San-Fu-Tie (OR: 1.17, 95% CI 1.08 to 1.27), manual acupuncture (OR:1.15, 95% CI 1.07 to 1.24) compared with conventional western medicine treatment. Moreover, direct comparison of the follow-up period showed that the clinical outcomes of acupuncture and related therapies at three-month (OR:1.34, 95% CI 1.17 to 1.55), six-month (OR: 1.31, 95% CI 1.10 to 1.57), and twelve-month (OR: 1.30, 95%CI 1.11 to 1.53) follow-up were better than those of traditional western medicine. CONCLUSION: These results indicate that for patients with allergic rhinitis who are unresponsive to conventional western medicine or cannot tolerate the side effects, acupuncture at the sphenopalatine ganglion acupoint is an effective alternative therapy. Further studies are advocated to deeply explore methodological quality of SRs by incorporating high-quality RCTs.

Efficacy Comparison of Different Acupuncture Treatments for Functional Dyspepsia: A Systematic Review with Network Meta-Analysis.

BACKGROUND: Acupuncture has been found to be an effective treatment for functional dyspepsia (FD). Currently, several types of acupuncture have been developed but it is not clear which type is suitable for FD. Currently, doctors often rely on experience to decide which form of acupuncture to apply. Herein, we employed network meta-analysis (NMA) to compare the effectiveness of various methods of acupuncture in the treatment of functional dyspepsia. METHODS: We searched for randomized controlled trials (RCTs) of acupuncture treatments for functional dyspepsia in seven databases; PubMed, the Cochrane Library, Embase, Wanfang database, China National Knowledge Infrastructure (CNKI) database, Chinese Science and Technique Journals (CQVIP), and Chinese Biomedical Database (CBM) from the date of database inception to October 10, 2019. Cochrane risk of bias tool was used to analyze the risk of bias of the included RCTs. Pairwise meta-analyses were performed with RevMan 5.3 and the network meta-analysis of the included RCTs was performed using the frequentist framework. RESULTS: A total of 35 studies involving 3301 patients and 10 interventions were eligible for this study. NMA results showed that five types of acupuncture (manual acupuncture, acupoint application, moxibustion, acupoint catgut embedding, and warm acupuncture alone) all were superior to prokinetics (itopride, mosapride, and domperidone) and sham acupuncture in terms of improving the symptoms of functional dyspepsia. Specifically, manual acupuncture and electroacupuncture were more effective in improving the MOS 36 Item Short-Form Health Survey (SF-36) compared to itopride and sham acupuncture, and electroacupuncture was the best among the three acupuncture therapies (acupuncture, electroacupuncture, and acupoint catgut embedding). Moxibustion and manual acupuncture were more effective in improving Nepean Dyspepsia Life Quality Index (NDLQI) compared to itopride, domperidone, and sham acupuncture; moxibustion ranks first among the three acupuncture therapies (acupuncture, electroacupuncture, moxibustion). CONCLUSIONS: These results showed that manual acupuncture alone was the most effective therapy for FD. It should, therefore, be considered as an alternative treatment for FD patients who are unresponsive to prokinetics or intolerant to the adverse effects of prokinetics. We recommend further multiple centers and high-quality RCT studies to confirm the present findings.
