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.

Objective:To establish the acute symptomatic osteoporotic thoracolumbar fracture (ASOTLF) classification system, and to examine the reliability and evaluate the effect of clinical application.Methods:A retrospective case series study was conducted to analyze the clinical data of 1 293 patients with osteoporotic thoracolumbar fracture(OTLF) admitted to Honghui Hospital from January 2016 to December 2018. There were 514 males and 779 females, aged 57-90 years [(71.4±6.3)years]. The T value of bone mass density was -5.0--2.5 SD [(-3.1±-0.4)SD]. According to the clinical symptoms a and fracture morphology, OTLF was divided into 4 types, namely type I(I occult fracture), type II(compressed fracture), type III (burst fracture) and type IV(unstable fracture). The type II was subdivided into three subtypes (type IIA, IIB, IIC), and the Type III into two subtypes (type IIIA, IIIB). of all patients, 75 patients (5.8%) were with type I, 500 (38.7%) with type II A, 134 (10.4%) with type IIB, 97 (7.5%) with type IIC, 442 (34.2%) with type IIIA, 27(2.1%) with type IIIB and 18 (1.4%) with type IV. After testing the validity of the classification, different treatment methods were utilized according to the classification, including percutaneous vertebroplasty (PVP) for Type I, PVP after postural reduction for Type II, percutaneous kyphoplasty (PKP) for Type IIIA, posterior reduction and decompression, bone graft fusion and bone cement-augmented screw fixation for Type IIIB, and posterior reduction, bone graft fusion and bone cement-augmented screw fixation for Type IV. The visual analog score (VAS), Oswestry disability index (ODI), Frankel grade of spinal cord injury, local Cobb Angle, and vertebral body angle (vertebral body angle) were recorded in all patients and in each type of patients before surgery, at 1 month after surgery and at the last follow-up. The neurological function recovery and complications were also recorded.Results:The patients were followed up for 24-43 months [(29.9±5.1)months]. A total of 3 000 assessments in two rounds were conducted by three observers. The overall κ value of inter-observer credibility was 0.83, and the overall κ value of intra-observer credibility was 0.88. The VAS and ODI of all patients were (5.8±0.7)points and 72.5±6.6 before surgery, (1.8±0.6)points and 25.0±6.3 at 1 month after surgery, and (1.5±0.6)points and 19.5±6.2 at the last follow-up, respectively (all P<0.05). The Cobb angle and vertebral body angle of all patients were (13.0±9.1)° and (8.0±4.6)° before surgery, (7.9±5.2)° and (4.6±2.9)° at 1 month after surgery, and (9.1±6.0)° and (5.8±3.0)° at the last follow-up, respectively (all P<0.05). At the last follow-up, VAS, ODI, Cobb Angle and VBA of each type of patients were significantly improved compared with those before surgery (all P<0.05). The spinal cord compression symptoms were found 1 patient with type IV and 5 patients with type IIIB preoperatively. At the last follow-up, neurological function improved from grade C to grade E in 1 patient and from grade D to grade E in 5 patients ( P<0.05). The lower limb radiation pain or numbness in 3 patients with type IV and 22 patients with type III preoperatively were fully recovered after surgical treatment at the last follow-up except for three patients. Conclusions:The ASOTLF classification is established and has high consistency and reliability. The classification-oriented treatment strategy has achieved a relatively satisfactory effect, indicating that the classification has a certain guiding significance for treatment of OTLF.

Objective To investigate the expression levels of microRNA(miR)-125b, miR-29a and miR-155-5p in ce?rebrospinal fluid (CSF) and plasma from the patients with tuberculous meningitis and their clinic significance. Methods Cerebrospinal fluid and plasma samples were collected from 20 patients with tuberculous meningitis (tuberculous meningitis group) and 20 patients suffered from primary headache (control group). The total RNAs were extracted.The levels of miR-125b, miR-29a and miR-155-5p were determined by real-time quantitative PCR (q-PCR). Results Levels of miR-29a and miR-125b in both CSF and plasma of patients in tuberculous meningitis group were significantly higher than those in pa?tients from control group with statistical significance (P<0.01). Mean time, the level of miR-155-5p in plasma but not in CSF of patients in tuberculous meningitis group was higher than those in control group with statistical significance ( P<0.01). Conclusion Expression of miR-125b, miR-29a and miR-155-5p may participate in regulating the occurrence and development of tuberculous meningitis. And miR-125b and miR-29a may be used as potential biomarkers for diagnosing tu?berculous meningitis.
