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 explore the microstructural characteristics of white matter in patients with acute ischemic stroke and their relationship with collateral circulation.Methods In all,150 patients with acute ischemic stroke admitted to our hospi-tal from January 2023 to May 2024 were selected as the study subjects,and another 150 healthy volunteers during the same peri-od were selected as the control group to compare the general clinical data of the two groups.All subjects underwent head MRI examination to extract microstructural features of brain white matter and analyze the correlation between microstructural fea-tures of brain white matter and brain white matter lesions.According to the formation status of collateral circulation,150 pa-tients with acuteischemic stroke were divided into good collateralcirculation group(n=91)and poor collateral circulation group(n=59).The general clinical data and microstructure characteristics of white matter were compared between the two groups.The predictive value of microstructurecharacteristics of white matter for stroke,white matter lesions,and poor collater-al circulation were analyzed using ROC curves.Results Comparing the general information between the healthy group and the stroke group,it could be seen that there were significant differences between the two groups in terms of smoking history,hyper-lipidemia history,hypertension history,LDL-C,HDL-C,FIB,and D-D(all P<0.05);The brain white matter fiber bundles with statistically significant FA values in the healthy and stroke groups included:cerebellar peduncle,pontine chiasmatic tract,corpus callosum,fornix column and fornix body,right corticospinal tract,left corticospinal tract,right cerebellar peduncle,left cerebellar peduncle,right anterior radial crown,and left anterior radial crown;The brain white matter fiber bundles with statistically sig-nificant MD values in the healthy and stroke groups included:cerebellar peduncle,pontine chiasmatic tract,right cerebellar pe-duncle,left cerebellar peduncle,right external capsule,left external capsule,and right frontal occipital bundle;The brain white matter fiber bundles with statistically significant RD values in the healthy and stroke groups included:cerebellar peduncle,pon-tine chiasmatic tract,left corticospinal tract,right cerebellar peduncle,left cerebellar peduncle,right cerebellar peduncle,left cer-ebellar peduncle,right external capsule,and left external capsule;The brain white matter fiber bundles with statistically signifi-cant AD values in the healthy and stroke groups included:midcerebellar peduncle,right medial thalamus,left medial thalamus,right superior cerebellar peduncle,left superior cerebellar peduncle,right posterior thalamic radiation,right sagittal layer,right external capsule,left external capsule,right cingulate and left cingulate.Correlation analysis showed that the FA values of the cerebellar peduncle,pontine chiasmatic tract,corpus callosum,fornix column and fornix body,right corticospinal tract,left corti-cospinal tract,right cerebellar peduncle,left cerebellar peduncle,right anterior radial crown,and left anterior radial crown were significantly negatively correlated with the white matter lesion score(all P<0.05);The MD values of the cerebellar peduncle,pontine chiasmatic tract,right cerebellar peduncle,left cerebellar peduncle,right external capsule,left external capsule,and right frontal occipital tract were significantly positively correlated with the white matter lesion score(all P<0.05);The RD values of the cerebellar peduncle,pontine chiasmatic tract,left corticospinal tract,right cerebellar peduncle,left cerebellar peduncle,right cerebellar peduncle,left cerebellar peduncle,right external capsule,and left external capsule were significantly positively correla-ted with the white matter lesion score(all P<0.05);The AD values of the cerebellar peduncle,right cerebellar peduncle,left cerebellar peduncle,right external capsule,and left external capsule were significantly positively correlated with the white matter lesion score(all P<0.05),while the AD values of the right medial thalamus,left medial thalamus,right posterior thalamus radi-ation,right sagittal layer,right cingulate and left cingulate were significantly negatively correlated with the white matter lesion score(all P<0.05).Comparing the general information between good collateral circulation group and poor collateral circulation group,it could be seen that there was a significant difference in the white matter lesion score between the two groups of patients(P<0.05).The ROC analysis showed that FA,MD,RD,and AD values in the cerebellar midfoot had good predictive value for stroke,white matter injury,and collateral circulation disorders,and the combined diagnostic efficacy of the four values was high-er than the diagnostic efficacy of each value alone.Conclusion The microstructure of white matter in patients with acute ische-mic stroke exhibits varying degrees of damage.Changes in FA,MD,AD,and RD values in the white matter of the cerebellar pe-duncle can be used to differentiate collateral circulation status,and the combined diagnostic efficacy of the four is better.

Objective:To investigate the prognosis of postoperative adjuvant therapy for hepatocellular carcinoma after conversion therapy of combined targeted therapy and immunotherapy followed by sequential hepatectomy.Methods:The retrospective cohort study was conducted. The clinicopathological data of 103 patients with initially unresectable hepatocellular carcinoma (HCC) who were admitted to 11 medical centers in China, including Mengchao Hepatobiliary Hospital of Fujian Medical University et al, from November 2019 to May 2023 were collected. There were 83 males and 20 females, aged (54±12)years. All 103 patients underwent conversion therapy of tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs) successfully followed by sequential hepatectomy, of which 72 patients undergoing postoperative adjuvant therapy were divided into the adjuvant therapy group, and 31 patients undergoing postoperative follow-up monitoring were divided into the follow-up monitoring group. Observation indicators: (1) follow-up and postoperative condi-tions; (2) analysis of factors influencing recurrence-free survival time of patients; (3) stratified ana-lysis. Comparison of count data between group was conducted using the chi-square test or Fisher exact probability. The R software was used to draw survival curves, and the Log-rank test was used for survival analysis. Univariate and multivariate analyses were conducted using the Cox proportional hazard model. Results:(1) Follow-up and postoperative conditions. All 103 patients were followed up for 21.0(range, 1.9?47.2)months, with the median recurrence-free survival time of 28.7 months and the 1-, 2-, 3-year recurrence-free survival rates of 68.6%, 55.6%, 41.2%. The median overall survival time of 103 patients was unreached, and the 1-, 2-, 3-year overall survival rates were 90.9%, 82.1%, 69.6%, respectively. The median recurrence-free survival time was 33.1 months in patients of the adjuvant therapy group, with the 1-, 2-year recurrence-free survival rates as 77.2%, 61.5%. The median recurrence-free survival time was 11.1 months in patients of the follow-up monitoring group, with the 1-, 2-year recurrence-free survival rates as 46.6%, 40.8%. There was a significant difference in recurrence-free survival between the two groups of patients ( χ2=5.492, P<0.05). (2) Analysis of factors influencing recurrence-free survival time of patients. Results of multivariate analy-sis showed that pathologic complete response and postoperative adjuvant therapy were independent factors influencing recurrence-free survival time of HCC patients undergoing conversion therapy of combined targeted therapy and immunotherapy followed by sequential hepatectomy ( hazard ratio=0.297, 0.492, 95% confidence interval as 0.137?0.647, 0.268?0.903, P<0.05). (3) Stratified analysis. Of the 71 patients with non-pathologic complete response, the median recurrence-free survival time of 48 patients in the adjuvant therapy group was 24.0 months, with the 1-, 2-year recurrence-free survival rates as 67.4%, 48.8%. The median recurrence-free survival time of 23 patients with non-pathological complete response in the follow-up monitoring group was 7.4 months, with the 1-, 2-year recurrence-free survival rates as 35.0%, 26.3%. There was a significant difference in recurrence-free survival between the 48 patients with non-pathologic complete response in the adjuvant therapy group and the 23 patients with non-pathologic complete response in the follow-up monitoring group ( χ2=5.241, P<0.05). Conclusion:For HCC patients with conversion therapy of TKIs and ICIs followed by sequential hepatectomy, postoperative adjuvant therapy, compared to postoperative follow-up monitoring, can prolong the recurrence-free survival time of patients, of whom cases with non-pathologic complete response can benefit from adjuvant therapy.

Objective To investigate the impact of myeloid cell-specific knockout of the granulocyte colony-stimulating factor receptor(G-CSFR)on the progression of acute radiation pneumonitis.Methods Myeloid cell-specific G-CSFR knockout(G-CSFR-/-,Lyz2-cre)mice were constructed.G-CSFR-/-,Lyz2-cre and C57BL/6N mice underwent a single whole-body irradiation with 6.5 Gy of 60Co γ-rays to establish a model of radiation injury.The lung function of mice was assessed using a mouse lung function test system at 3,7 and 14-days post γ-ray irradiation.Pathological changes in the lung tissue were analyzed via hematoxylin and eosin(HE)staining of paraffin sections.Tumor necrosis factor-α(TNF-α)and interleukin-10(IL-10)levels were measured via radioimmunoassay.IL-8 and its receptor CXCR2 were quantified using enzyme-linked immunosorbent assay(ELISA).The infiltration of neutrophils in lung tissue was evaluated by immunohistochemical detection of myeloperoxidase.Results At 3-,7-and 14-days post-irradiation with 6.5 Gy of 60Co γ-rays,there were no significant differences observed in lung function or interstitial inflammatory lesions between G-CSFR-/-,Lyz2-cre mice and C57BL/6N mice.However,the infiltration of neutrophils in lung tissue of G-CSFR-/-,Lyz2-cre mice was significantly reduced(P＜0.01),and the levels of IL-8,CXCR2 and TNF-α in lung tissues were markedly lower than in C57BL/6N mice(P＜0.05).Conclusion The myeloid cell-specific knockout of G-CSFR can effectively diminish neutrophil infiltration as well as inflammatory cytokine levels in lung tissues following radiation exposure.

Objective To explore the factors influencing cognitive dysfunction in patients with vestibular migraines.Methods The clinical data of 298 patients with vestibular migraine admitted to the Second People's Hospital of Guiyang City from January 2020 to Ja-nuary 2024 were retrospectively analyzed.The patients were divided into a cognitive impairment group(n=55)and a non-cognitive impairment group(n=243).Baseline data such as sex,age,body mass index,and educational level between the two groups of patients were matched using propensity score matching in a 1∶1 ratio.Factors influencing cognitive dysfunction in patients with vestibular migraine were screened using single-factor and multiple logistic regression analyses.Results Fifty pairs of patients were successfully matched.Single-factor and multivariate logistic regression analyses showed that migraine duration≥10 years,sleep disorders,anxiety or depression,threatened migraine,and white matter lesions were risk factors for cognitive impairment in patients with vestibular migraine(P＜0.05).Conclusion Duration of migraine,sleep disorders,anxiety or depression,threatened migraine,and white matter lesions are factors influencing cognitive dysfunction in patients with vestibular migraine.Corresponding intervention strategies can be developed for risk factors to reduce the occurrence of cognitive dysfunction and improve prognosis.

Objective:To evaluate the advantages and short-term clinical effects of totally robotic Nissen 360° fundoplication compared with laparoscopic surgery.Methods:A retrospective analysis was conducted on data of 110 patients undergoing Nissen 360° fundoplication at the Second Department of General Surgery, Yan'an Hospital Affiliated to Kunming Medical University from Aug 2023 to Aug 2024. Among them, 50 cases underwent totally robotic fundoplication, and 60 cases underwent laparoscopic fundoplication. By comparing and analyzing the fatigue level of the primary surgeon during the operations, postoperative incisional pain in patients, swallowing function recovery and the time to resume a normal solid-food diet within 3 months post-surgery, the advantages of totally robotic surgery were evaluated. Additionally, by examining the postoperative recovery of reflux symptoms, postoperative patient comfort, and satisfaction levels in both groups, the short-term clinical outcomes of totally robotic surgery were assessed.Results:Both groups of patients successfully completed the surgeries without any intraoperative or postoperative complications occurring. The fatigue score of the primary surgeon in the totally robotic group was significantly better than that in the laparoscopic group[ (2.34±1.38) vs. (2.89±1.51), t=1.385, P<0.01]. The time taken to resume a normal solid-food diet postoperatively in the totally robotic group was significantly shorter than that in the laparoscopic group[ (27.90±6.77) d vs. (40.78±13.60) d, t =5.765, P<0.01]. Moreover, the postoperative pain comfort level was better in the robotic group than in the laparoscopic group [(1.65±0.72) points vs. (2.23±0.59) points, t=3.742, P<0.01]. Within 12 months postoperatively, the GERD-Q scores in the totally robotic group decreased significantly, and reflux symptoms disappeared, comparable to that in the laparoscopic group. Conclusions:The totally robotic Nissen 360° fundoplication leads to lower fatigue levels for the surgeon. Patients experience significant advantages in terms of postoperative pain perception and dietary recovery. Additionally, it demonstrates excellent postoperative anti-reflux efficacy, high patient comfort, and the surgery is safe and reliable.

Objective To determine the effect of non-high-density lipoprotein cholesterol(non-HDL-C)on all-cause and cause-specific mortality in an ≥60-year-old elderly population.Methods A total of 16 642 older adults(≥60 years)were subjected from the National Health and Nutrition Examination Survey between 1999 and 2018.According to the tertile of non-HDL-C level,the par-ticipants were divided into tertile 1(＜3.15 mmol/L,n=5499),tertile 2(3.15-4.06 mmol/L,n=5499),and tertile 3 groups(＞4.06 mmol/L,n=5644).The occurrences of all-cause,cardiovascu-lar,and non-cardiovascular death were identified as the study endpoint.Cox proportional hazards regression,Kaplan-Meier survival and restricted cubic spline curve analyses were applied for sta-tistical study.Results An obvious L-shaped associations were observed in non-HDL-C level with risks for all-cause,cardiovascular,and non-cardiovascular death.After adjusting multivariable,the tertile 1 group had significantly higher risks for all-cause,cardiovascular,and non-cardiovascular death than the tertile 2 group(HR=1.123,95％CI:1.054-1.200,P=0.000;HR=1.142,95％CI:1.024-1.292,P=0.027;HR=1.113,95％CI:1.033-1.210,P=0.011).Kaplan-Meier survival analysis showed that the tertile 1 group had notably lower survival rate than the tertile 2 group and the tertile 3 group(P＜0.01).Threshold effect analysis revealed that when non-HDL-C level was lower than 3.36,3.18 and 3.59 mmol/L,respectively,the risk of all-cause,cardiovascular,and noncardiovascular mortality was increased.Conclusion In the elderly ≥60-year-old population,non-HDL-C level exhibited a L-shaped association with all-cause and cause-specific mortality,and＞3.18 mmol/L is regarded as a rational range.
