Purpose: Acupoint herbal patching (AHP) is extensively used in treatment of allergic rhinitis in China. However, existing systematic review is insufficient. To evaluate the effectiveness and safety of AHP in treating allergic rhinitis.Methods: We searched seven electronic databases for RCTs from inception until August 2014. Two authors selected studies, extracted data and evaluated risk of bias independently. The Cochrane risk of bias tool was applied to assess the methodological quality of the included trials and RevMan 5.2 software was utilised to perform data analysis.Results: Twenty RCTs involving 2438 participants were included. Most of them were evaluated as high risk of bias. AHP significantly decreased the recurrence rate at six months compared with western medicine (RR 0.52; 95% CI 0.42 to 0.64), and similar effect was found for AHP plus western medicine versus western medicine (RR 0.53; 95% CI 0.44 to 0.65). AHP appeared to be more effective than placebo in improving total clinical symptoms and signs after treatment and at 6 months, and in improving quality of life at less than 3 months and over 3 months. No severe adverse effects were found in the AHP groups.Conclusion: AHP alone or combined with western medicine appears to be more effective than placebo or western medicine respectively. AHP seems to be a safe treatment. However, the findings should be interpreted with caution. Further largescale, rigorously designed trials are warranted to confirm the findings.Contact: Jianping Liu, Jianping

Objective To assess the cardiovascular safety of celecoxib compared to non-selective non-steroid anti-inflammatory drugs or placebo. Methods We included randomized controlled trials of oral celecoxib compared with a non-selective NSAID or placebo in rheumatoid arthritis and osteoarthritis patients. We conducted searches in EMBASE, Cochrane CENTRAL, MEDLINE, China National Knowledge Infrastructure, VIP, Wanfang, and Chinese Biomedical Literature Database. Study selection and data extraction were done by two authors independently. The risk of bias was assessed using Cochrane’s risk-of-bias Tool for Randomized Trials. The effect size was presented as a risk ratio with their 95% confidence interval. Results Until July 22nd, 2021, our search identified 6279 records from which, after exclusions, 21 trials were included in the meta-analysis. The overall pooled risk ratio for Antiplatelet Trialists Collaboration cardiovascular events for celecoxib compared with any non-selective non-steroid anti-inflammatory drugs was 0.89 (95% confidence interval: 0.80–1.00). The pooled risk ratio for all-cause mortality for celecoxib compared with non-selective non-steroid anti-inflammatory drugs was 0.81 (95% confidence interval: 0.66–0.98). The cardiovascular mortality rate of celecoxib was lower than non-selective non-steroid anti-inflammatory drugs (risk ratio: 0.75, 95% confidence interval: 0.57–0.99). There was no significant difference between celecoxib and non-selective non-steroid anti-inflammatory drugs or placebo in the risk of other cardiovascular events. Conclusion Celecoxib is relatively safe in rheumatoid arthritis and osteoarthritis patients, independent of dose or duration. But it remains uncertain whether this would remain the same in patients treated with aspirin and patients with established cardiovascular diseases.

The existing evidence for the beneficial effect and safety of Chinese herbal medicine for idiopathic sudden sensorineural hearing loss comes from methodologically poor studies and therefore cannot be reliably used to support their clinical use. We identify a justification to further investigate the effect and safety of Chinese herbal medicine for people with idiopathic sudden sensorineural hearing loss in rigorously designed randomised trials.

Objective: To evaluate the efficacy, clinical effectiveness, and safety of the Chinese herb Bupleuri radix for the treatment of acute uncomplicated respiratory tract infections (ARTIs).Methods: Four English and four Chinese databases were searched from their inception to June 2021. Randomized controlled trials (RCTs) assessing therapeutic effects of Bupleuri radix on ARTI were eligible for inclusion. The risk of bias for each trial was assessed using the Cochrane Risk of Bias Tool 2.0. RevMan 5.4 software was used for data analyses with effects estimated as risk ratios (RR) or mean differences (MD) with 95% confidence intervals (CI). The certainty of the evidence was assessed using the online GRADEpro tool.Results: Seven randomized trials involving 910 patients with acute upper respiratory tract infection (AURTI) were included. The review identified Bupleuri radix agents with four administration routes (oral, acupoint injection, intramuscular injection, nebulized inhalation). Bupleuri radix acupoint injection compared with placebo showed statistically significant effects in reducing fever resolution time (MD: −33.32 h, 95%CI: −35.71, −30.93), and in increasing the proportion of participants with fever resolved within 48 h from treatment onset (RR: 14, 95%CI: 1.96, 99.94). Bupleuri radix acupoint injection combined with usual care is more effective in reducing the temperature at day 1 from treatment onset (MD: −1.00°C, 95%CI: −1.19, −0.81) compared with usual care alone. Bupleuri radix pills showed similar antipyretic effects to acetaminophen. However, Bupleuri radix intramuscular injection plus vitamins failed to demonstrate an effect in reducing fever, when compared with ribavirin plus vitamins. It suggested that oral administration of Bupleuri radix solution for injections, pills, and Bupleuri radix decoction have a similar effect on improving global AURTI symptoms including two key symptoms (nasal discharge and cough), when compared with usual care alone. Only two trials reported whether or not there were any AEs and found no occurrence of adverse events in the herbal group.Conclusion: Low-certainty or very low-certainty evidence demonstrated that Bupleuri radix (solution for injections and pills) has an antipyretic effect on febrile patients with AURTI, but it has no effect on other AURTI symptoms. However, these findings need to be further confirmed by well-designed clinical trials with adequate sample sizes.Systematic review registration: (https://www.crd.york.ac.uk/prospero/#recordDetails), PROSPERO registration number: CRD42021234066.
