Cardiologists currently exhibit a low level of compliance with their specialty's guidelines for postinfarction beta-blockade. Slightly fewer than 50% of the study patients who were eligible for treatment actually received a beta-blocker after hospital discharge. This result, combined with the drug's known level of effectiveness in preventing recurrent myocardial infarction, suggests that increased use could avert approximately 1,900 deaths annually nationwide.

Background. Knee osteoarthritis (KOA) can cause chronic pain and seriously affect the quality of patient lives. The continued emergence of high-quality RCTS requires us to update the quality of evidence. This study aims to evaluate the efficacy of acupuncture for KOA patients and calculate the required information size (RIS) to determine whether further clinical studies are required. Methods. We searched PubMed, Embase, WOS, CBM, CNKI, VIP, WHO ICTRP, ChiCTR, and Grey literature to collect randomized controlled trials (RCTs) of acupuncture for KOA from inception to December 2021. A meta-analysis was performed according to the Cochrane systematic review method by using Review Manager 5.4 and TSA 0.9.5.10 beta, and GRADE was used to evaluate the quality of the evidence. Trial sequential analysis was used to control random errors and calculate the required information size. Results. Eleven RCTs with 2484 patients were included in our meta-analysis, meeting the inclusion criteria for the meta-analysis. The meta-analysis indicated that acupuncture had beneficial effect on knee osteoarthritis in reducing pain [ n = 2387 ; SMD = − 0.12 , 95% CI (-0.20, -0.04); I 2 = 0 % ] and improved patients function activities [ n = 2408 ; MD = − 1.25 , 95% CI (-1.97, -0.53); I 2 = 0 % ], but true acupuncture showed no significant effect in relieve patient’s stiffness [ n = 1337 ; MD = − 0.07 , 95% CI (-0.30, 0.15); I 2 = 0 % ]. We pooled the studies which found no significant difference in improving the quality life of mental [ n = 1462 ; SMD = 0.02 , 95% CI (-0.23, 0.27); I 2 = 78 % ] and patients physical health (SF-36 or SF-12) [ n = 1745 ; SMD = 1.01 , 95% CI (-0.08, 2.11); I 2 = 0 % ] compared with sham acupuncture. The pain and function TSA graphs indicated that cumulative Z-curves intersected with the traditional level of statistical favoring acupuncture, and more RCTs will required in the future studies. Conclusion. Acupuncture has beneficial effect on pain relief and improves function activities, and this treatment can be recommended as a beneficial alternative therapy in patients with KOA, particularly for chronic patients and those currently undergoing long-term pain and help them increasing quality of life. But it should be further verified through more RCTs in function. Available studies suggested that acupuncture was superior to sham acupuncture in reduce pain and function as verified by TSA.

Background Researches on the central mechanisms of acupuncture analgesia have been widely conducted worldwide. However, there is no bibliometric analysis of functional magnetic resonance imaging (fMRI) studies on acupuncture analgesia. This study visualized the current status, hot spots and frontiers of fMRI studies on acupuncture analgesia in the past 20 years to provide a theoretical basis for its clinical application. Methods All publications were obtained from Science Citation Index-Expanded (SCI-E) of Web of Science (WOS). We used CiteSpace to analyze publications, journals, cited journals, authors, cited authors, institutions, countries, references, and keywords. We also analyzed collaborative network maps and co-occurrence network maps. Results We retrieved a total of 797 articles. Regarding the volume of publications, the total number of annual publications showed a fluctuating but overall increasing trend. Evidence-based Complementary and Alternative Medicine (21 articles) was the most productive journal, and Pain (225 articles) was the most cited journal. The most productive author was Qin W (16 articles), and the most co-cited author was Hui KKS (111). The most prolific institution and country were Massachusetts General Hospital (34 articles) and USA (212 articles). “Pain” was the top-ranked for keyword frequency and centrality. “Functional connectivity” was the frontier hotspot for 2018–2021. Conclusion First, fMRI researches on acupuncture analgesia involved several countries (regions) and institutions, mainly located in the USA, China and Korea, and most of them were universities. In addition, the USA was a major contributor in this field. Second, in terms of disciplinary distribution, the literatures were mainly from clinical neurology, neuroscience, and radiology nuclear medicine medical imaging. Third, the keyword co-occurrence analysis showed that the hot keywords included pain, fMRI, and lower back pain. Fourth, through keyword clustering analysis, the hot disease was found to be lower back pain, and the hot contents were acupuncture specificity and frequency specificity. Fifth, a timeline analysis of the references identified that chronic low back pain and specificity will remain a hot topic for future research.

The current reporting format of ADR/AE in clinical CM injections is not standardized. Much fundamental information of ADR/AE following CM injection is therefore missing. A standard reporting format for ADR should be developed, and should include the following: (1) a title mentioning adverse effects and safety; (2) a structured abstract including adequate information about the patient and the disease treated, the drug used, the specific ADR/AE, physician response to the ADR/AE, and result of management; (3) demographic characteristic of the patients (gender, age, etc.); (4) clinical characteristics of patients (disease, syndrome, etc); (5) allergic history of patients; (6) diagnosis and syndrome based on Chinese medicine theory; (7) detailed information about the CM intervention (the manufacturer of the drug, series number, valid dates, dosage, route of administration, menstruum, dripping speed, etc.); (8) concomitant drug use; (9) time and symptoms of ADR/AE; (10) type and grading of ADR/AE; (11) physiological systems affected by ADR/AE; (12) specific treatment and prognosis for ADR/AE; (13) evidence of the cause and effect of ADR/AE; and (14) any other possibility of ADR/AE. Also, a ADR/AE registration system should be established.
