Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

Objective:To review the literature on improving patients′medical experience, analyze the current research status in this field, and provide references for enhancing patients′medical experience.Methods:A search was conducted for studies related to improving patients′medical experience published from January 2015 to November 2024 in eight databases, including CNKI and Web of Science. Using software CiteSpace 6.4.R1 and VOSviewer 1.6.19 to analyze publication trends, keyword clustering, existing problems in the process of improving patients′medical experience, and the measures taken.Results:6 507 articles were included, of which 4 452 were in English (68.4%) and 2 055 were in Chinese (31.6%). The annual number of publications showed a nearly linear growth trend ( R2 = 0.983 9). The clustering analysis results indicated that domestic and international research mainly focused on patient-centered diagnostic and treatment systems, behaviors, services, and environments. Existing studies revealed that there were still problems such as long waiting times for appointments and consultations (292 articles), uneven distribution of medical resources (198 articles), and poor doctor-patient communication (155 articles). To improve patients′medical experience, the following intervention measures were proposed: accelerating the medical reform process and strengthening government responsibilities (169 articles); enhancing service concepts and innovating service models (363 articles); optimizing the consultation process and simplifying medical procedures (221 articles); improving the consultation environment and optimizing the facilities in the consultation area (181 articles); and integrating technological advantages to cover the entire medical process (346 articles). Conclusions:Research on improving patients' medical experience was increasingly attracting the attention of more and more scholars. Issues such as low service efficiency, unbalanced resource allocation, and poor doctor-patient communication need to be given special attention. In the future, it is recommended to enhance the experience of patients′ medical experience by strengthening policy and institutional guarantees, accelerating the construction of information technology, improving doctor-patient communication skills and humanistic care, and enhancing the capacity of primary medical services.

Objective:To study the effects of Shengui Jiajian Pills on myocardial fibrosis and the transforming growth factor-β1 (TGF-β1)/Smads signaling pathway in elderly rats with hypothyroidism; To preliminarily explore the mechanism of Shengui Jiajian Pills in treating hypothyroid heart disease through the TGF-β1/Smads pathway.Methods:Totally 60 SD rats were randomly divided into normal group, model group, sodium levothyroxine group, and Shengui Jiajian Pills low-, medium-, and high-dosage groups, with 10 rats in each group. A model of elderly hypothyroid heart injury in rats was prepared by freely drinking 0.1% propylthiouracil (PTU) for 10 weeks. Each group of rats was gavaged with the corresponding drug once a day for 6 weeks. After the last gastric lavage, an electrocardiogram was performed, hematoxylin-eosin staining (HE) was used to observe pathological changes in the heart tissue; bitter acid-toluidine blue staining was used to detect fibrosis of the heart tissue; TUNEL staining was used to observe myocardial cell apoptosis; Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of thyroid stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4) in the serum, as well as brain natriuretic peptide (BNP), creatine kinase isoenzymes MB (CK-MB), and lactate dehydrogenase (LDH); Western blot was used to detect the relative expressions of TGF-β1, p-Smad2, p-Smad3, α-smooth muscle actin (α-SMA), matrix metalloproteinase-1 (MMP-1), TIMP1, Bax, and Caspase-3 in the heart tissue; and immunofluorescence was used to detect the positive expressions of TGF-β1, Smad3, α-SMA, and MMP-1 in the heart tissue.Results:Compared with the model group, the inflammatory cell infiltration and cell damage in the heart of rats in each dosage group of Shengui Jiajian Pills were improved, the myocardial fibrosis area ratio was significantly reduced ( P<0.05), and the myocardial cell apoptosis rate significantly decreased ( P<0.05), the levels of TSH, BNP, CLD, and HK-MB in serum significantly decreased ( P<0.05). The levels of FT3 and FT4 increased in the Shengui Jiajian Pills medium- and high-dosage groups ( P<0.05), while the positive expressions of TGF-β1, Smad3, α-SMA, and MMP-1 decreased ( P<0.05). The protein expression of TGF-β1, p-Smad3, MMP-1, Bax, and Caspase-3 decreased ( P<0.05), and the expression of TIMP-1 increased ( P<0.05). The expression of Smad7 increased in the Shengui Jiajian Pills medium-dosage group ( P<0.05). Conclusion:Shengui Jiajian Pills may reduce myocardial collagen fiber deposition by modulating the TGF-β1/Smad3 signaling pathway, thereby partially reversing the pathological features of hypothyroidism-induced myocardial injury, with more pronounced effects observed in the medium and high dosage groups.

The anterior cruciate ligament (ACL) injury is a common sports injury that has a significant impact on knee function and patients′ mobility. With the popularity of national fitness campaign in China, the incidence of ACL injury is increasing year by year. Currently, there still lacks clinical standards or guidelines on how to choose appropriate treatment methods, surgical plans and rehabilitation protocols for ACL injury. In order to timely reflect the new treatment concept of ACL injury, standardize its diagnosis and treatment and improve the curative effect, the Sports Medicine Society of Chinese Research Hospital Association and the Editorial Board of Chinese Journal of Trauma organized domestic orthopedic and sports medicine experts to formulate the "clinical evidence-based guideline for the diagnosis and treatment of anterior cruciate ligament injury (2022 version)" based on the level of evidence-based medicine and in compliance with the principle of scientificity, practicability and advancement. The present guideline includes 12 recommendations for the diagnosis, treatment and rehabilitation of ACL injury in order to provide guidance and assistance for the clinical diagnosis and treatment of ACL injury in China.

Objective:To analyze the results of polysomnography(PSG) in 523 children, and explore the sleep monitoring results and related influencing factors of obstructive sleep apnea hypopnea syndrome(OSAHS).Methods:The PSG monitoring results of children with OSAHS and non-OSAHS were analyzed for children aging from 0 to 16 years old, who were monitored at Sleep Medicine Center of Gansu Maternal and Child Health Hospital from January 2014 to December 2019.Results:A total of 523 children underwent PSG monitoring during the past 5 years.The male to female ratio was 1∶0.47, of which 66.9%(350/523)were children with OSAHS.The average proportion of rapid eye movement sleep was 1.95%(7.7/394). The height of non-OSAHS group was significantly higher than that of OSAHS group[(108.72±16.39)cm vs.(104.80±16.60)cm, P=0.016]. The incidence of OSAHS decreased with age( P=0.038). The apnea index, hypopnea index, apnea hypopnea index, obstructive apnea index, microarousal index, oxygen desaturation index, mean apnea time, and longest apnea time in the OSAHS group were higher than those in the non-OSAHS group( P<0.05). And the lowest oxygen saturation and the mean oxygen saturation during sleep were lower than those in the non-OSAHS group( P<0.05). Logistic regression analysis on the clinical data of OSAHS children showed that open mouth breathing and snoring at night had significant effects on children′s OSAHS, and the differences were statistically significant( P<0.05). Conclusion:PSG is of great significance for the diagnosis of OSAHS.The more severe the degree of OSAHS, the worse severe the night sleep hypoxemia.PSG should be recommended before taking any treatment for children with sleep disorders.
