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.

[Purpose]To analyze the trends of mortality and disease burden of gastric cancer among residents aged 30 and above from 2009 to 2023 in Wuxi City of Jiangsu Province and to estimate the age-period-cohort effect.[Methods]The gastric cancer mortality data from 2009 to 2023 were collected from Wuxi Death Registration System,and the crude mortality rate,age-standardized mortality rate,years of life lost(YLL)and YLL rate were calculated.The average annual percen-tage change(AAPC)was calculated with Joinpoint regression to analyze the trends of mortality and YLL rate of gastric cancer.The age-period-cohort model was used to analyze the effect of age,pe-riod and birth cohort on gastric cancer mortality.[Results]From 2009 to 2023,there were 32 348 gastric cancer deaths in Wuxi,the crude mortality rate was 44.24/105,and the age-standard mor-tality rate was 25.10/105,with a total YLL of 681 618.33 person-years.The crude mortality rate,age-standardized mortality rate and YLL rate showed decreasing trends,with AAPC of-1.77％(95％CI:-2.10％～-1.43％),-4.59％(95％CI:-4.97％～-4.20％)and-2.14％(95％CI:-2.56％～-1.74％),respectively.From 2009 to 2023,crude mortality rate,age-tandardized mortality rate,YLL in men were higher than those in women,and the decline rates of all indicators in women were faster than those in men.The age effect showed that the overall risk of gastric cancer death increased with age;the period effect showed a gradual decrease in the mortality risk and death burden of gastric cancer over time;the cohort effect showed that the later born cohort had a lower risk of death and death burden.[Conclusion]From 2009 to 2023,the disease burden of gastric cancer mortality in Wuxi showed a decreasing trend,with age and sex being the primary influencing factors.In the future,emphasis should be placed on gastric cancer screening and early intervention in middle-aged and elderly men.

Objective:To compare the dosimetric differences between volumetric modulated arc therapy(VMAT)and helical tomotherapy(HT)in undergoing protective plan for pelvic bones of patients with cervical cancer.Methods:A total of 40 patients with cervical cancer,who underwent radiotherapy at the First Affiliated Hospital of Bengbu Medical University from January 2023 to February 2024,were selected for this study.The target volumes and organs at risk(OARs)were delineated after the information of computed tomography(CT)simulation images were acquired from each patient.The pelvic bone was alone delineated as OAR.Two kinds of bone marrow dose-limiting radiotherapy plans,coplanar dual-arc VMAT and HT,were respectively designed for each patient by using the treatment planning system(TPS)of radiotherapy.A statistical analysis was conducted to compare the dose parameters of target volume,conformity,homogeneity,OAR dose-volume,mean dose,and maximum dose of point between the two kinds of plans.Results:Both the VMAT and HT plans could meet the requirements of target volume and OARs for dose.For general OARs,the dose-volume percentage(V40 Gy)of V40 Gy at bladder,mean dose(Dmean),rectal V40 Gy,maximum dose(Dmax)at small intestine point of HT plan were respectively(38.97±2.29)%,(38.06±0.45)Gy,(61.50±2.51)%and(50.82±0.36)Gy.The differences of them between HT plan and VMAT plan were statistically significant(t=25.46,13.99,1.56,10.93,P<0.05).The V10 Gy,V20 Gy,V30 Gy and Dmean of VMAT plan were respectively(70.76±2.51)%,(60.84±3.29)%,(52.40±2.56)%and(32.02±4.33)Gy for pelvic bones,which were significantly lower than those of HT plan,and the differences of them between two kinds of plans were also statistically significant(t=-20.68,-13.23,-7.73,-10.26,P<0.05).Conclusion:The HT plan can provide the optimal dose distribution for target region in radiotherapy for patients with cervical cancer,which can better protect OAR nearby target region.VMAT plan has a significant advantage in low-dose regions of protecting pelvis.Thus,individualized treatment design should be conducted according to the conditions of each patient in clinical treatment.

Objective To construct an MRI radiomics model of cerebral damage following carbon monoxide(CO)poisoning.Methods Ninety patients with CO poisoning and 70 healthy controls(HC)were scanned by structural MRI.All patients were randomly divided into training set(n=128)and test set in a ratio of 8∶2.The radiomics features of 9 regions of interest(ROI)were automatically extracted,and each ROI was subjected to 5-fold cross-validation and 9 different types of classifiers to construct a diagnostic model.Receiver operating characteristic(ROC)curve and decision curve analysis(DCA)were used to evaluate the diagnostic efficacy and clinical value of the model.Results The model based on the radiomics features of the whole brain gray matter(GM)and the left globus pallidus(LGP)had better diagnostic efficacy and clinical application value.The area under the curve(AUC)in the training set and the test set were 0.813,0.815 and 0.806,0.806,respectively.Conclusion The GM-based radiomics model can effectively diagnose cerebral damage following CO poisoning.

Objective To explore the role of the brief visuospatial memory test-revised(BVMT-R)in predicting the clinical conversion to psychosis in subjects with clinical high-risk for psychosis(CHR-P).Methods A total of 217 CHR subjects were recruited and assessed using BVMT-R at baseline.Participants were followed up for three years to determine whether they converted to psychosis.The relationship between BVMT-R total score and CHR-P conversion probability was analyzed using generalized additive model,and the cutoff values of BVMT-R total score for predicting CHR-P conversion were calculated by maximally selected rank statistics.Then,the total BVMT-R score was stratified into different intervals based on the cutoff values obtained as previously described.Finally,the positive likelihood ratios and the conversion rates at different time points were calculated for each interval.Results A total of 168 subjects with CHR-P completed the 3-year follow-up assessment.According to the results of the generalized additive model,the relationship between the BVMT-R total score and CHR-P conversion probability exhibited the characteristics of a piecewise function model.The cutoff values identified using the maximally selected rank statistics method were 18 and 29,which divided the BVMT-R total scores into three intervals:0-18,19-29,and 30-36.The positive likelihood ratios of the three intervals for predicting CHR-P psychosis conversion were significantly different(all P<0.01).All three intervals had significantly different rates of psychosis conversion at different follow-up time points(all P<0.01).Conclusion The total BVMT-R score can be divided into three intervals,each associated with a distinct positive likelihood ratio for predicting psychosis conversion in CHR-P individuals.Accordingly,the BVMT-R total score may serve as a preliminary indicator for estimating the probability of psychosis conversion in the CHR-P population.

Japanese encephalitis is an acute central nervous system infectious disease caused by Japanese encephalitis virus (JEV) with brain parenchyma inflammation, characterized by high fever, headache, positive meningeal irritation, impaired consciousness, convulsion, and respiratory failure, with mortality rate as high as 20%-30%, and with neurological sequelae in 30%-50% of survivors. The mechanism of brain damage caused by JEV infection is still unclear, and some studies imply its close relation with immune-inflammatory response. This article reviews the research progress on immune-inflammatory response mechanism of Japanese encephalitis to help to understand its pathogenesis.
