Objective:To evaluate the clinical effects of anatomical reconstruction of the deltoid ligament and medial migration calcaneal osteotomy in the treatment of chronic ankle instability after trauma.Methods:A retrospective study was conducted to analyze of the clinical data of 16 patients with chronic post-traumatic instability of the medial malleolus who had been treated at The Eighth Department of Orthopedics, Foshan Hospital of Traditional Chinese Medicine from December 2015 to February 2017. There were 14 males and 2 females with an age of (28.1±4.2) years. Seven left sides and 9 right sides were affected; the time from injury to operation was (8.9±2.4) months. Before operation, X-rays (anteroposterior, lateral and Saltzman views) and MRI of weight-bearing ankle were taken. All patients were treated by anatomical reconstruction of the deltoid ligament using the autologous semitendinosus and medial migration osteotomy of the calcaneus. The time for injury healing and occurrence of complications were recorded. The talus tilt angle, Meary angle, hindfoot valgus angle, visual analogue scale (VAS), and the American Orthopedic Foot & Ankle Society (AOFAS) ankle-hindfoot function score were compared between the preoperation and the last follow-up. The Sefton evaluation for efficacy in ankle ligament reconstruction was used to assess stability of the ankle joint.Results:Of this cohort, 14 patients were followed up for (16.4±4.9) months after operation and 2 patients lost to follow-up. The 14 patients all returned to normal physical activities 3 months after operation. All incisions healed at the first stage with no infection. One patient experienced pain at the site for harvest of the semitendinosus but the symptoms were relieved after rehabilitation treatment like massage and physical therapy. At the last follow-up, the talus tilt angle [1.0 (0.0, 2.0)°], Meary angle (1.4°±4.2°), hindfoot valgus angle (3.2°±2.4°), VAS score [0.5 (0.0, 1.0) points], and AOFAS ankle-hindfoot score [(89.2±6.1) points] were all significantly improved compared with the preoperative values [8.3°±1.8°, 0.8°±3.8°, 9.9°±3.4°, (5.7±2.5) points, and (49.6±9.8) points] (all P<0.05). According to the Sefton evaluation, the stability of the ankle joint was excellent in 9 cases, good in 4 cases, and fair in 1 case. Conclusion:In the treatment of chronic ankle instability after trauma, anatomical reconstruction of the deltoid ligament and medial migration calcaneal osteotomy is safe and effective, resulting in limited complications.

The characterization of the human T-cell receptor (TCR) repertoire has made remarkable progress, with most of the work focusing on the TCRβ chains. Here, we analyzed the diversity and complexity of both the TCRα and TCRβ repertoires of three healthy donors. We found that the diversity of the TCRα repertoire is higher than that of the TCRβ repertoire, whereas the usages of the V and J genes tended to be preferential with similar TRAV and TRAJ patterns in all three donors. The V-J pairings, like the V and J gene usages, were slightly preferential. We also found that the TRDV1 gene rearranges with the majority of TRAJ genes, suggesting that TRDV1 is a shared TRAV/DV gene (TRAV42/DV1). Moreover, we uncovered the presence of tandem TRBD (TRB D gene) usage in ~2% of the productive human TCRβ CDR3 sequences.

Chest trauma is one of the most common injuries. Venous thromboembolism (VTE) as a common complication of chest trauma seriously affects the quality of patients′ life and even leads to death. Although there are some consensus and guidelines on the prevention and treatment of VTE at home and abroad, the current literatures lack specificity considering the diagnosis, treatment and prevention of VTE in patients with chest trauma have their own characteristics, especially for those with blunt trauma. Accordingly, China Chest Injury Research Society and editorial board of Chinese Journal of Traumatology organized relevant domestic experts to jointly formulate the Chinese expert consensus on the diagnosis, treatment and prevention of chest trauma venous thromboembolism associated with chest trauma (2022 version). This consensus provides expert recommendations of different levels as academic guidance in terms of the characteristics, clinical manifestations, risk assessment, diagnosis, treatment, and prevention of chest trauma-related VTE, so as to offer a reference for clinical application.

The discussion and research on the clinical dominant diseases of traditional Chinese medicine （TCM） have attracted increasing attention. Through approaches including modern technology， evidence-based medical methods， and multi-disciplinary treatment， we should construct a sound TCM inheritance and innovation system， establish a collaborative innovation mechanism， and integrate major research projects， striving to make breakthroughs in TCM theory， methodology， standards， and regulation system， promoting the scientific and technological progress of TCM， and thereby improving its curative effect. The China Association of Chinese Medicine （CACM） carried out a series of youth salon seminars for clinical dominant diseases in TCM， discussing and sorting out the advantages of the dominant diseases in clinical diagnosis and treatment of TCM and integrated traditional Chinese and western medicine in specific diseases or fields. Authoritative experts in the industry were invited to give comment and guidance to form a report. Centering on clinical research of dominant diseases， thematic research was carried out in the aspects of practice， human experience-based evidence， and transformation path. Through the systematic study of the dominant diseases， the advantages of TCM in different stages of disease treatment were excavated to constantly improve the prevention and treatment ability of TCM and carry forward the advancement of TCM theory and practice. At the same time， the communication and understanding between traditional Chinese and western medicine were improved， laying the foundation for the further formation of industry guidelines or consensus and comprehensive promotion. These seminars are expected to provide references for the development of policy planning， clinical diagnosis and treatment， health economy， and social services in TCM and lay the foundation for the formation of a new modern diagnosis and treatment system with Chinese characteristics.
