Objective To understand the research status and development trend in the field of molecular and cell biology of thyroid cancer.Methods Relevant literature published in the field of molecular and cell biology of thyroid cancer from January 1,2013 to December 31,2022 was obtained in the web of science core collection(WoSCC)according to the search conditions,and bibliometric and visual analysis were performed using the bibliometric software VOSviewer and Excel.Results A total of 1 627 literatures were included.Among them,113 papers were published in 2013,and 214 were published in 2022.The annual number of publications was on the rise.There were 9 274 authors in total,of whom 6 published no less than 10 literatures.There were a total of 2 042 institutions,of which the top 10 institutions were mostly Chinese universities.There were 68 countries in total,and the largest number of publications was China,followed by the United States.There were 513 journals in total,and the top 10 journals with the largest number of literatures were mainly in the field of oncology,followed by the field of endocrinology and metabolism.A total of 62 563 references from 5 887 journals were cited.The most co-cited journal was Journal of Biological Chemistry(1 608 times),and the most co-cited references was Molecular Pathogenesis and Mechanisms of Thyroid Cancer(89 times).Conclusion The field of molecular and cell biology of thyroid cancer is currently developing steadily.Ferroptosis,glycosylation,telomerase reverse transcriptase and oxidative stress are the research frontiers in this field.

OBJECTIVE: To evaluate the operability and effectiveness of a self-developed patellar bone canal locator (hereinafter referred to as "locator") in the reconstruction of the medial patellofemoral ligament (MPFL). METHODS: A total of 38 patients with recurrent patellar dislocation who met the selection criteria admitted between January 2022 and December 2022 were randomly divided into study group (the patellar canal was established with a locator during MPFL reconstruction) and control group (no locator was used in MPFL reconstruction), with 19 cases in each group. There was no significant difference in baseline data between the two groups ( P>0.05), such as gender, age, body mass index, disease duration, patella Wiberg classification, constituent ratio of cartilage injury, Caton index, tibia tubercle-trochlear groove, and preoperative Lysholm score, Kujal score, Tegner score, visual analogue scale (VAS) score, and so on. The Lysholm score, Kujal score, Tegner score, and VAS score were used to evaluate knee joint function before operation and at 3 days,1 month, 3 months, and 6 months after operation. The ideal prepatellar cortical thickness and canal length were measured before operation, and the actual prepatellar cortical thickness and canal length after operation were also measured, and D1 (the distance between the ideal entrance and the actual entrance), D2 (the ideal canal length minus the actual canal length), D3 (the ideal prepatellar cortical thickness minus the actual prepatellar cortical thickness) were calculated. RESULTS: Patients in both groups were followed up 6-8 months (mean, 6.7 months). The incision length and intraoperative blood loss in the study group were smaller than those in the control group, but the operation time was longer than that in the control group, the differences were significant ( P<0.05). There was no complication such as incision infection, effusion, and delayed healing in both groups, and no further dislocation occurred during follow-up. One patient in the study group had persistent pain in the anserine area after operation, and the symptoms were relieved after physiotherapy. The VAS score of the two groups increased significantly at 3 days after operation, and gradually decreased with the extension of time; the change trends of Lysholm score, Kujal score, and Tegner score were opposite to VAS score. Except that the Lysholm score and Kujal score of the study group were higher than those of the control group at 3 days after operation, and the VAS score of the study group was lower than that of the control group at 3 days and 1 month after operation, the differences were significant ( P<0.05), there was no significant difference in the scores between the two groups at other time points ( P>0.05). Patellar bone canal evaluation showed that there was no significant difference in preoperative simulated ideal canal length, prepatellar cortical thickness, and postoperative actual canal length between the two groups ( P>0.05). The postoperative actual prepatellar cortical thickness of the study group was significantly smaller than that of the control group ( P<0.05). D1 and D3 in the study group were significantly higher than those in control group ( P<0.05), but there was no significant difference in D2 between the two groups ( P>0.05). CONCLUSION The locator can improve the accuracy of MPFL reconstruction surgery, reduce the possibility of intraoperative damage to the articular surface of patella and postoperative patellar fractures.
