Background Acupuncture has been widely applied to relieve knee osteoarthritis (KOA) in many countries. However, the bibliometric analysis of the global use of acupuncture on KOA is largely unknown. Therefore, this study aimed to explore the current status and trends of the global use of acupuncture on KOA in recent 10 years by using CiteSpace (5.6.R3). Methods Publications regarding acupuncture therapy for treating KOA between 2010 and 2019 were extracted from the Web of Science database. CiteSpace was used to analyze the number of publications, countries, institutions, journals, authors, cited references and keywords by using standard bibliometric indicators. Results A total of 343 publications were retrieved from 2010 to 2019. The total number of publications continually increased over the past four years, and the most active journals, countries, institutions and authors in the field of acupuncture therapy on patients with KOA were identified. The Evid Based Complement Alternat Med (28) was the most prolific journal, and the Ann Intern Med (202) was the most cited journal. The most productive country and institution in this field was China (115) and University of York (18), respectively. Hugh Macpherson (18) was the most prolific author and Witt C ranked the first in the cited authors. In the ranking of frequency in cited reference, the first article was published by Scharf HP (54). The keyword of ‘randomized controlled trial’ ranked first for research developments with the highest citation burst (3.9486). Besides, there were three main frontiers in keywords for KOA research, including ‘research method, ‘age’ and ‘measure of intervention’. Conclusion The findings from this bibliometric study provide current status and trends in clinical research of acupuncture therapy on patients with KOA over the past ten years, which may help researchers identify hot topics and explore new directions for future research in this field.

Background In recent years, many studies have examined risks factors that facilitated the transition from suicide ideation to suicide attempts. Few studies, however, have examined protective factors against this transition. The current study thus assessed two protective factors, self‐compassion and family cohesion, in buffering the transition from suicide ideation to suicide attempts. Method A number of 520 Chinese adolescents (43.46% females, mean age = 12.96 years) completed questionnaires assessing self‐compassion, family cohesion, suicide ideation, and suicide attempts two times with a 12‐month interval. Results Self‐compassion significantly moderated the association between Wave 1 SI and later SA. The positive dimension of self‐compassion thwarted the transition from SI and SA, and the negative dimension of self‐compassion strengthened the associations. In addition, family cohesion also significantly moderated the transition from SI to SA. Conclusion Increasing the levels of self‐compassion and family cohesion may be the targets for treating adolescents with suicide ideation to prevent them from attempting suicide.

IntroductionPostherpetic neuralgia (PHN) is the most common sequela of herpes zoster, and it is often refractory to guideline-recommended treatments. Acupuncture therapy, a wildly applied complementary-alternative treatment, may help in the management of PHN. Diverse types of acupuncture therapy for PHN have been proposed, however, their comparative efficacies remain unclear. This study protocol plans to compare the efficacy and safety of different acupuncture therapies for PHN.Methods and analysisDatabases including MEDLINE, Embase, Cochrane Library, Web of Science, Chinese Biomedical Database, China National Knowledge Infrastructure, VIP Database, Wanfang Database, WHO International Clinical Trials Registry Platform, ClinicalTrials.gov, Chinese Clinical Trial Register and OpenGrey will be searched from their inception to January 2022. Randomised controlled trials (RCTs) assessing the effectiveness of acupuncture therapy on the management of PHN will be selected. The primary outcome is pain intensity. Secondary outcomes include negative emotions, sleep condition, quality of life and adverse events. Reviewers will conduct study selection, data extraction and risk of bias assessment procedures. Then, standard pair-wised meta-analysis and Bayesian network meta-analysis will be performed (if applicable). The Confidence in Network Meta-Analysis application will be used to assess the confidence in the evidence for the primary outcome.Ethics and disseminationAll data used for this study will be extracted from published RCTs, thus, no ethical approval will be required. The results of this systematic review will be disseminated through peer-reviewed journal and conference presentation.PROSPERO registration numberCRD42020219576.

Objective Research suggests that emotional abuse is associated with adolescent suicidal ideation. But how they are related is still unclear. The present study tested the temporal relationship between emotional abuse and suicidal ideation, with psychache as the potential mediator. We also examined the reciprocal relationship between psychache and suicidal ideation. Method A number of 2,259 Chinese high school students (53.8% females, mean age = 15.11, SD = 1.57) in Hong Kong completed questionnaires assessing emotional abuse, psychache, and suicidal ideation three times at 6‐month intervals. Results The results supported the mediating effect of psychache in the path from emotional abuse to suicidal ideation. In addition, psychache and suicidal ideation were related reciprocally over time. Conclusion The findings of this study may help researchers and practitioners understand the pathways by which emotional abuse impacts adolescent suicidal ideation. Implications for preventions and interventions of suicidal ideation were discussed.

Introduction: Classical trigeminal neuralgia (CTN) is a kind of trigeminal neuralgia which is due to neurovascular compression. The common neurological treatment CTN drug called carbamazepine is the main measure, although it usually has side effects and a high-rate of relapse. As a critical alternative therapy, electroacupuncture (EA) has been shown to benefit for neuropathic pain. The aims of this study are to observe the therapeutic effect and safety of EA for CTN, to evaluate whether EA has the advantage over carbamazepine in the analgesia of CTN. Furthermore, we would to establish a standardized, effective, and convenient therapy program of EA. Methods and analysis: One hundred twenty patients diagnosed with CTN will be randomized for a 4-week intervention. The interventions will be different according to the four groups (EA + carbamazepine group, sham EA + carbamazepine group, EA + placebo group and sham EA + placebo group). EA therapy will be performed in specific acupoints with a dilute wave (2/100 Hz) for 60 minutes. Carbamazepine tablets will be taken orally with 0.1 g each time, thrice daily. Sham EA and placebo intervention will not receive EA and drug treatment. The main outcomes are the change from baseline intensity of pain at 6 months (pain evaluation by visual analogue score) and the change from baseline brief introduction of 2-week pain to evaluate pain comprehensively. The data management and statistical analysis will be conducted by third party statisticians. Incidence of adverse events will be investigated. Ethics and dissemination: Ethics approval was obtained from the Clinical Trial Ethics Committee of The Third Affiliated Hospital of Zhejiang Chinese Medical University (NO. ZSLL-KY-2017-033) and Jiaxing Hospital of Traditional Chinese Medicine (NO. 2018-JZLK-002). The results will be disseminated by presentation at peer-reviewed journals.
