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.

With the development of the medical cosmetology industry, the market demand for medical sodium hyaluronate dressing is gradually increasing, but at present the product lacks the corresponding national standards. This problem makes this type of product face the problem of non-uniform standards in the quality control, registration declaration information content, technical review requirements, and other aspects. In this review paper, the classification of medical sodium hyaluronate wound dressing products was introduced, and the key points of the technical review were discussed, involving the division of the registration unit, raw material control, product performance indicators, and clinical evaluation. In addition, the key information review requirements in the process of registration and declaration of such products were analyzed, with a view to providing technical references for manufacturers and relevant regulatory agencies.

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.
