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 investigate the contents of natural radionuclides in agricultural soils in some of Gansu Hexi area to accumulate the relevant basic data.Methods:A stratified sampling method was used to collect 146 soil samples in the area. ORTEC P-type HPGE gamma spectrometry system was used to measure radionuclides. The measurement data were collated and analyzed.Results:The activity concentrations measured were 232Th 18.94-108.39 Bq/kg, 226Ra 14.37-79.20 Bq/kg and 40K 440.03-1 358.18 Bq/kg, in turn with the mean values of (68.22±16.32), (47.90±11.12) and (763.90±133.93) Bq/kg, respectively. The difference in activity concentrations of 232Th, 226Ra and 40K in agricultural soils in different areas was statistically significant( H=50.87, 45.14, 40.28, P<0.05). Conclusions:The study on the activity concentrations of natural radionuclides in agricultural soils provides basic information for the transfer of radionuclides to crops, which needs further investigation, monitoring and analysis.

Objective:To compare the effects of intermittent oro-esophageal tube feeding (IOE) and nasogastric tube feeding (NGT) on nutritional status, complications, swallowing function and airway protection in persons with post-stroke dysphagia (PSD).Methods:Sixty PSD patients were randomized into an observation group ( n=30) and a control group ( n=30). In addition to conventional medication and swallowing rehabilitation, the observation group received supplemental IOE nutrition, while the control group was given NGT. Before and after one month, both groups were evaluated using the Functional Oral Intake Scale (FOIS), and such nutritional indicators as body mass index (BMI), hemoglobin (Hb) levels, albumin (ALB), prealbumin (PAB), skinfold at the triceps (TSF) and arm muscle circumference (AMC) were measured. The morphology of each subject′s epiglottis, any edema of the arytenoid mucosa and vocal cord mobility were assessed using fiberoptic endoscopic evaluation of swallowing (FEES). Murray Secretion Scale ratings were documented, along with laryngeal sensation during swallowing, swallowing reflex, the Yale Pharyngeal Residue Severity Rating Scale, and the Rosenbek Penetration-aspiration Scale. Results:Both groups showed significant improvement in their average FOIS scores and all of the nutritional descriptors, but with significantly greater improvement in the observation group. Abnormalities in the shape of the epiglottis, arytenoid edema and vocal cord mobility had decreased significantly in both groups. This was also true of larynx sensation, swallowing reflex, pharyngeal secretions, residue and penetration/aspiration. On average the improvements were significantly greater in the observation group.Conclusion:Compared with NGT, IOE more effectively improves swallowing, enhances airway functioning and reduces NGT syndrome among PSD patients. These observations support its clinical adoption.

Objective To analyse the causal relationship between obstructive sleep apnea(OSA)and atrial fibrillation(AF)by Mendelian randomization(MR)method,and to explore the role of inflammatory factors,immune cells,blood metabolites and circulating proteins in it.Methods In this study,MR analysis was used to investigate the causal link between OSA and AF.Inverse variance weighting(IVW),MR-Egger and other methods were used for sensitivity analysis.Additionally,the study also explored the effects of 91 inflammatory factors,731 immune cells,1 400 blood metabolites and 4 907 circulating proteins on AF.Results MR analysis revealed a significant causal relationship between OSA and AF(OR=1.078,P＜0.05).Conversely,reverse MR analysis did not find causal relationship between AF and OSA(P＞0.05).Further analysis revealed that 5 inflammatory factors,19 immune cells,15 blood metabolites and 67 circulating proteins were risk factors for AF.Among them,OSA was the risk factor for one inflammatory factor,one blood metabolite and 12 circulating proteins.There was no significant causal association between OSA and 19 immune cells.Conclusion This study demonstrates that OSA increases the risk of AF.Meanwhile,it is found that inflammatory factors,immune cells,blood metabolites and circulating proteins have potential impacts on the pathogenesis of AF.

Objective:To analyze the efficacy and safety of nalbuphine for analgesia in patients with non-mechanical ventilation in intensive care unit (ICU).Methods:From December 2018 to August 2021, a multicenter randomized controlled clinical study was conducted to select non-mechanical ventilation patients with analgesic needs admitted to ICU of four hospitals in Henan Province and Guizhou Province. Patients were randomly assigned to nalbuphine group and fentanyl group. The nalbuphine group was given continuous infusion of nalbuphine [0.05~0.20 mg/(kg·h)], and the fentanyl group was given continuous infusion of fentanyl [0.5~2.0 μg/(kg·h)]. The analgesic target was critical-care pain observation tool (CPOT) score<2. The observation time was 48 hours. The primary endpoint was CPOT score, the secondary endpoints were Richmond agitation-sedation score (RASS), ICU length of stay, adverse events, and proportion of mechanical ventilation. The quantitative data of the two groups were compared by t test or Mann-Whitney U test. The enumeration data were compared by chi square test or Fisher exact probability method. The data at different time points between groups were compared by repeated measures analysis of variance. Results:A total of 210 patients were enrolled, including 105 patients in the nalbuphine group and 105 patients in the fentanyl group. There was no significant difference in baseline data between the two groups (all P>0.05). There was no significant difference in CPOT score between nalbuphine group and fentanyl group at each time point after medication ( P>0.05), the CPOT score of both groups at each time point after medication was significantly lower than that before medication, and the analgesic target could be achieved and maintained 2 hours after medication. There was no significant difference in RASS between the two groups at each time point after medication ( P>0.05), which was significantly lower than that before medication, and the target sedative effect was achieved 2 hours after medication. There was no significant difference in ICU length of stay between nalbuphine group and fentanyl group [5.0(4.0,7.5) d vs. 5.0(4.0,8.0) d, P=0.504]. The incidence of delirium, nausea and vomiting, abdominal distension, pruritus, vertigo and other adverse events in the nalbuphine group was lower than that in the fentanyl group (all P<0.05). There was no significant difference in the incidence of other adverse events such as deep sedation, hypotension and bradycardia between the two groups (all P>0.05). The incidence of respiratory depression in nalbuphine group was not significantly different from that in fentanyl group ( P>0.05), but the proportion of mechanical ventilation was significantly lower than that in the fentanyl group [1.9% (2/105) vs. 8.6%(9/105), P=0.030]. Conclusions:Nalbuphine could be used for analgesia in ICU patients with non-mechanical ventilation. The target analgesic effect could be achieved within 2 hours, and it had a certain sedative effect with a low incidence of adverse reactions.

Objective To explore the effectiveness of high-definition diffusion weighted imaging(DWI)sequence combined with T1 WI-fat suppression(FS)dynamic contrast enhancement(DCE)sequence for preoperative T-stage of rectal cancer by using 3.0T MRI standardized scanning.Methods A retrospective analysis was conducted on MRI images of 57 patients with rectal cancer confirmed by pathology.Before surgery,the patients underwent 3.0T MRI standardized rectal cancer scan methods,including routine sequence,high-definition DWI sequence,and T1 WI-FS DCE sequence,etc.Then two experienced physicians evaluated the T-stage of preoperative rectal cancer through high-definition DWI(transverse and sagittal sections)and T1 WI-FS DCE sequences in the double-blind method.Using the postoperative pathological results of rectal cancer as the"gold standard",two sequences were combined to evaluate the accuracy,sensitivity,and specificity of rectal cancer T-stage.Results Among the 57 cases,there were 9 cases of upper rectal cancer,39 cases of middle rectal cancer,and 9 cases of lower rectal cancer.The accuracy rates of preoperative T-stage diagnosis for rectal cancer by two evaluator were both 85.7％(6/7)in T1 stage,88.2％(15/17)and 94.1％(16/17)in T2 stage,96.9％(31/32)and 93.8％(30/32)in T3 stage,and both 100.0％(1/1)in T4 stage.For evaluator 1,the sensitivity and specificity of the rectal cancer T-stage diagnosis were 96.1％and 83.3％,and for evaluator 2 were 94.1％and 83.3％,respectively.For rectal cancer MRI diagnosis,the accuracy rates and sensitivity were higher when combining the high-definition DWI sequence and T1 WI-FS DCE sequence,compared with a single high-definition DWI sequence or T1 WI-FS DCE sequence,and the difference was statistically significant.The average preoperative apparent diffusion coefficient(ADC)value of rectal cancer was compared between the corresponding postoperative pathological T1 to T4 stage groups,and the difference was statistically significant.Conclusion The combination of high-definition DWI sequence and T1 WI-FS DCE sequence improves the accuracy of rectal cancer T-stage,providing assistance for personalized clinical treatment.
