To explore the characteristics of benign paroxysmal positional vertigo (BPPV) and examine the efficacy of Canalith repositioning in elders.A retrospective study was carried out among 47 BPPV cases at our hospital from January 2011 to June 2012.Posterior semicircular canal received Epley maneuver (n =35) and Lempert rolling for horizontal semicircular canal (n =12).Curative effect was evaluated after 1 week and 3 months.After Canalith repositioning,the initial success rate was 91.5％ (43/47) and the effective rate 8.5％ (4/47).After 1 week,the success rate was 100％.Nine patients (19.1％) had recurrence in the same canal previously affected,and all improved with a new repositioning maneuver.Canalith repositioning is both safe and effective in the treatment of BPPV.

This study searched the clinical researches on traditional Chinese medicine （TCM） for cardiovascular diseases registered in Chinese Clinical Trial Registry and the US Clinical Trial Registry， the cardiovascular disease-related studies funded by the National Natural Science Foundation of China， as well as those published in China National Knowledge Infrastructure （CNKI）， Wanfang database， VIP.com， China Biology Medicine disc （CBMdisc）， Embase， Medline， Cochrane Library， and other databases published cardiovascular disease-related studies from 1 January 2021 to 30 June 2023. In order to analyse and evaluate the research progress of TCM treatment for coronary heart disease， hypertension， heart failure， and arrhythmia， this study aimed at recent research hotspots and research direction. It is found that the research on TCM for cardiovascular diseases was gradually deepening and the high-quality evidence continued to emerge. It is believed that studies related to the prevention and treatment of common cardiovascular diseases by TCM reflected the multi-angle integration of modern technology and pattern differentiation and treatment， closer integration of clinical and basic research， and further optimisation of pattern identification and interventions. On this basis， the research programme and implementation process should be further standardized， and the translation of research results should be emphasized to promote the standardized application and promotion of TCM diagnosis and treatment of cardiovascular diseases.
