Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

OBJECTIVES: This study aims to analyze the biomechanics of three kinds of rigid internal fixation methods for condylar head fractures. METHODS: A three dimensional finite element model of the normal mandible was constructed. It was then used to prepare condylar head fracture finite element model and three kinds of rigid internal fixation finite element model (unilateral tension screw, bilateral tension screw, tension screw+titanium plate). The mechanical characteristics and changes of the mandible condyle under the same mechanical conditions were compared among the three different rigid internal fixation methods. RESULTS: The maximum equivalent stress and displacement of the non-free end of condyle under the rigid internal fixation method of unilateral tension screw were 71.03 MPa and 4.72 mm, respectively. The maximum equivalent stress and displacement of the free end of condyle were 78.45 MPa and 4.50 mm, respectively. The maximum stress of fracture suture was 3.27 MPa. The maximum equivalent stress and displacement of the non-free end of condyle under the rigid internal fixation method of bilateral tension screw were 70.52 MPa and 4.00 mm, respectively. The maximum equivalent stress and displacement of the free end of condyle were 72.49 MPa and 3.85 mm, respectively. The maximum stress of fracture suture was 2.33 MPa. The maximum equivalent stress and maximum displacement of the non-free end of condyle under the rigid internal fixation method of tension screw+titanium plate were 67.26 MPa and 2.66 mm, respectively. The maximum equivalent stress and maximum displacement of the free end of condyle were 69.66 MPa and 2.50 mm, respectively. The maximum stress of fracture suture was 2.18 MPa. CONCLUSIONS The tension screw+titanium plate rigid internal fixation method is the most conducive to biomechanical distribution for condylar head fractures.

Objective:To investigate the dosimetric advantages of deep inspiration breath-hold (DIBH) technique in postoperative radiotherapy for left-sided breast cancer.Methods:A prospective study was conducted on patients requiring adjuvant radiotherapy after left-sided breast cancer surgery at Jiangsu Cancer Hospital from January 2018 to May 2023. CT simulation images were acquired under both free breathing (FB) and DIBH respiratory modes. Planning target volumes (PTV) and organs at risk (OAR) were delineated, and dosimetric parameters were compared between the two respiratory modes. Additionally, patients were grouped into subgroups [internal mammary lymph node irradiation (IMNI) vs. non-IMNI, breast-conserving surgery (BCS) followed by radiotherapy vs. modified radical mastectomy (MRM) followed by radiotherapy], and dosimetric differences among subgroups for both breathing modes were compared. The Velocity system was used to measure the minimum distances from the heart and left anterior descending coronary artery (LAD) to the PTV surface on CT images. These distances were defined as the heart-to-PTV and LAD-to-PTV distances. Pearson correlation analysis was performed to assess the relationships between heart D max and LAD D max, heart-to-PTV distance and heart D mean, and LAD-to-PTV distance and LAD D max under both respiratory modes. Results:A total of 132 patients were included. Compared to the FB, DIBH showed no significant difference in target dose distribution, but significantly reduced dose to OAR. Specifically, the heart D mean and D max decreased by 1.8 Gy and 8.1 Gy, respectively, and the LAD D max decreased by 7.9 Gy, and the affected lung V 5 Gy and V 20 Gy were reduced by 6.4% and 2.5%, respectively (all P<0.05). All subgroups benefited from DIBH, with greater decrease of dose to OAR in the IMNI subgroup (compared with the non-IMNI subgroup) and the subgroup of MRM followed by radiotherapy (compared with the BCS followed by radiotherapy group). Under both FB and DIBH modes, heart D max and LAD D max showed linear correlations ( r=0.62 and 0.84, respectively; both P<0.001), heart-to-PTV distance correlated with heart D mean ( r=-0.61 and -0.67, respectively; both P<0.001), and LAD-to-PTV distance correlated with LAD D max ( r=-0.58 and -0.63, respectively; both P<0.001). Conclusions:The DIBH technique can significantly reduce dose to the heart, LAD, and lungs in patients undergoing postoperative radiotherapy for left-sided breast cancer without compromising target dose. Patients receiving IMNI after left-sided breast cancer surgery benefit more from the DIBH technique.

ObjectiveTo evaluate the clinical efficacy of different acupuncture-related therapies in treating postoperative pain in patients with osteoporotic vertebral compression fractures (OVCFs) after percutaneous kyphoplasty (PKP) or percutaneous vertebroplasty (PVP) using a network meta-analysis.MethodsA systematic search was conducted in PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang Database, Chinese Scientific Journal Database, and Chinese Biomedical Literature Database (SinoMed) from their inception to January 15, 2025. Outcome measures included the Visual Analog Scale (VAS) score, Oswestry Disability Index (ODI) score, and overall efficacy rate. Literature screening, data extraction, and risk-of-bias assessment were independently performed by two researchers. Data analysis was conducted using Stata 17.0 software.ResultsA total of 35 randomized controlled trials involving 2860 patients were included. The data analysis revealed that, in terms of improving VAS and ODI scores, the top three effective therapies were Fu's subcutaneous needling, wrist-ankle acupuncture, and acupotomy. For the overall efficacy rates in pain treatment, the top three therapies were wrist-ankle acupuncture, warm acupuncture and moxibustion, and Fu's subcutaneous needling. Based on the combined results across the three outcome measures, Fu's subcutaneous needling was found to be the most effective in relieving pain and improving lumbar function.ConclusionFu's subcutaneous needling, wrist-ankle acupuncture, warm acupuncture and moxibustion, and acupotomy were all effective in treating postoperative pain post-PKP/PVP and improving lumbar function. However, further high-quality, large-sample studies are required to confirm these findings.

A case of giant liquid tophus in both lower legs was reported. The patient was a 41-year-old man with a history of gout for more than 10 years. The patient had hyperlipidemia and prediabetes, and the long-term use of hormone cortisol drugs was suspected. After standardized treatment for lowering uric acid, reducing blood lipids, and correcting glucose intolerance, the patient lost 12 kg over six months. The patient was admitted to the hospital upon discovering symmetrical enlargement of both calves. Ultrasound showed subcutaneous masses with clear boundaries behind the gastrocnemius muscle, approximately 14.9 cm×6.7 cm on the left and 13.6 cm×4.6 cm on the right. Based on the clinical information and morphological features, a diagnosis of gouty tophus was made. Following ultrasound-guided puncture drainage, aspirate about 200 mL fluid from the subcutaneous masses of each lower legs. The patient continued to receive standardized uric acid-lowering treatment and the patient′s condition improved. For such atypical giant liquid tophus, clinical practitioners should remain vigilant, differentiating them from tumors, infections, autoimmune diseases, and promptly perform pathological examinations through puncture to be diagnosed. After a definitive diagnosis, surgical excision can be performed concurrently with standardized uric acid-lowering treatment to achieve a favorable prognosis.

The correspondence between prescription and syndrome is the advantage and characteristic of traditional Chinese medicine(TCM)treatment.However,the pathogenesis of clinical diseases is complex and the condition is changeable,and the clinical application is difficult to achieve the maximum effect under the existing cognition of the correspondence between prescription and syndrome.In this paper,the five categories of physiological characteristics,pathological characteristics,constitution,syndrome,and disease of the longitudinal classification of"TCM state"are introduced into the correspondence of prescription and syndrome.Under the vertical perspective of"TCM state",the theoretical connotation of the correspondence between prescription and syndrome is interpreted as"correspondence between prescription and state",namely correspondence of"prescription-physiological characteristics",correspondence of"prescription-pathological characteristics",correspondence of"prescription-constitution",correspondence of"prescription-syndrome",and correspondence of"prescription-disease".It is hoped to accurately grasp the corresponding connotation of the correspondence between prescription and syndrome,in order to deepen the clinical thinking mode of TCM.

The theory of “diagnosing diseases with sinews” means that through the diagnosis and examination of the channel sinews at the site of the lesion， the surplus and deficit state of qi and blood in the channel sinews， vessles and channels， and the degree of damage to the organism caused by the disease and evils， can be determined， forming the three elements （the nature of the disease， the location of the disease， and the disease tendency） of the disease diagnosis can be closely integrated to form the trinity of diagnostic modes， which is “examining the disease nature by sinews， identifying the pattern by sinews， and determining the tendency by sinews”. For intractable facial paralysis， the method of “diagnosing diseases with sinews” can be adopted， in which the morphological changes of the channel sinews are judged through diagnosis by observation， the traditional Chinese patterns are identified through diagnosis by palpation， and the points of meridian tendons and the circulation of tendon and treatment lines are determined through diagnosis by circulation. The “diagnosing diseases with sinews” not only helps to accurately determine the disease condition， patterns and development trend， but also helps to adopt targeted treatment for the disease and prevent the disease from spreading， and providing ideas and methods for the clinical diagnosis and treatment of intractable facial paralysis.
