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.

Approximately 30%-40% of epilepsy patients do not respond well to adequate anti-seizure medications (ASMs), a condition known as pharmacoresistant epilepsy. The management of pharmacoresistant epilepsy remains an intractable issue in the clinic. Its early prediction is important for prevention and diagnosis. However, it still lacks effective predictors and approaches. Here, a classical model of pharmacoresistant temporal lobe epilepsy (TLE) was established to screen pharmacoresistant and pharmaco-responsive individuals by applying phenytoin to amygdaloid-kindled rats. Ictal electroencephalograms (EEGs) recorded before phenytoin treatment were analyzed. Based on ictal EEGs from pharmacoresistant and pharmaco-responsive rats, a convolutional neural network predictive model was constructed to predict pharmacoresistance, and achieved 78% prediction accuracy. We further found the ictal EEGs from pharmacoresistant rats have a lower gamma-band power, which was verified in seizure EEGs from pharmacoresistant TLE patients. Prospectively, therapies targeting the subiculum in those predicted as "pharmacoresistant" individual rats significantly reduced the subsequent occurrence of pharmacoresistance. These results demonstrate a new methodology to predict whether TLE individuals become resistant to ASMs in a classic pharmacoresistant TLE model. This may be of translational importance for the precise management of pharmacoresistant TLE.

Objective:To investigate the efficacy and safety of acute stent implantation during endovascular treatment for patients with emergent large vessel occlusion due to intracranial atherosclerotic stenosis.Methods:A retrospective analysis was carried out on 46 patients with emergent large vessel occlusion due to intracranial atherosclerotic stenosis who received endovascular treatment at the Strategic Support Force Medical Center from January 2015 to August 2022. Twenty-seven patients underwent balloon angioplasty alone and 19 patients underwent acute stent implantation. The baseline characteristics, modified thrombolysis in cerebral infarction (mTICI) score of the responsible vessels, modified Rankin scale (mRS) score 90 days after operation, incidence of symptomatic intracranial hemorrhage and mortality of the two groups were evaluated.Results:The proportion of effective recanalization of the offending vessels (mTICI≥2b) in the acute stenting group was slightly higher than that in the balloon angioplasty group (16/19 vs. 81.5%), but the difference was not statistically significant ( P>0.05). Besides, there was no significant difference in the median of mRS between the acute stenting group [3.0(0, 4.0)] and the balloon angioplasty group [4.0(1.0, 5.0)] 90 days after operation ( P>0.05). In terms of safety, the incidence of symptomatic intracranial hemorrhage and mortality were comparable between the two groups ( P>0.05). Conclusions:The effect of acute stent implantation during endovascular treatment for patients with emergent large vessel occlusion due to intracranial atherosclerotic stenosis is not inferior to that of balloon angioplasty, and it does not increase the risk of intracranial bleeding complications.

Objective:To retrospectively summarize the clinical characteristics and treatment of 49 patients with hyperthyroid cardiopath and to explore the diagnosis and treatment methods of hyperthyroid cardiopathy.Methods:A total of 49 patients with hyperthyroid cardiopath(HC group) who were successfully treated and followed up in the Department of Endocrinology, Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine, from January 2016 to December 2021 were collected, and 85 cases of Graves′ disease without heart disease were collected as the control group(GD group). The medical history, laboratory tests, and echocardiographic parameters of the two groups were compared. Differences in thyroid and cardiac indicators before and after treatment in the HC group were summarized, along with the dosage of β-receptor blockers used in treating different types of conditions(atrial fibrillation and heart failure.Results:Patients in the HC group were older and had a longer duration of hyperthyroidism than those in the GD group( P<0.001, P=0.002). There were no significant differences in thyroid hormone levels between the two groups except for reverse triiodothyronine(rT 3). Age and rT 3 were independent risk factors of hyperthyroid cardiopathy. rT 3 level was linearly positively correlated with brain natriuretic peptide, systolic pulmonary artery pressure, left artrium diamete (LAD) and left ventricular end-systolic diameter(LVDs; r=0.352, P<0.001; r=0.392, P=0.019; r=0.202, P=0.029; r=0.242, P=0.028). In patients of HC group, free triiodothyronine(FT 3) level returned to normal range after 2.87(1.63, 5.53) months of treatment with radioiodine(41/49) or antithyroid drugs(8/49), while brain natriuretic peptide, LAD, LVDs, and systolic pulmonary artery pressure declined after 5.00(1.25, 8.00) months of treatment. Non-selective β-receptor blockers were used for both hyperthyroid heart failure and atrial fibrillation, and there was no statistically significant difference in dosage[(86.52±47.83)mg vs(88.67±47.19)mg, P>0.05]. Conclusions:rT 3 may be a biomarker of hyperthyroid cardiopath and indicate the severity of hyperthyroidism. β-receptor blockers are crucial in treating patients with hyperthyroidism who develop atrial fibrillation and heart failure.

Objective:To explore the function of MDM2 and its relationship with p53 at the cellular level during H 2O 2 induced oxidative damage. Methods:MLE-12 HALI cell models were established using 0.5 mmol/L H 2O 2, and were divided into three groups: normal control group, H 2O 2 injury group, H 2O 2+MDM2 overexpressed group, and H 2O 2+MDM2 shRNA group. Infection of MLE-12 cells with adenovirus vector overexpressing and silencing MDM2; Using immunoprecipitation (Co-IP) to analyze the interaction between MDM2 and p53; Western blotting was used to detect the protein expression levels of MDM2, p53, Bcl-2, Bax, and cleared caspase-3 after HALI modeling; Measure the apoptosis rate of cells in each group. Results:After transcriptome sequencing,the p53 signaling pathway closely related to HALI. Compared with the normal group, the expression of MDM2 in the H 2O 2 injury group was lower ( P<0.05); Compared with the H 2O 2 injury group, overexpression of MDM2 resulted in a decrease in the apoptosis rate of MLE-12 cells ( P<0.05), a decrease in the expression levels of p53, Bax, and cleared caspase-3 proteins, and an upregulation of MDM2 and Bcl-2 protein expression ( P<0.05). Compared with the H 2O 2 injury group, when MDM2 was silenced, the cell apoptosis rate increased ( P<0.05), and the expression levels of p53, Bax, and cleared caspase-3 proteins were upregulated, while the expression levels of MDM2 and Bcl-2 proteins decreased ( P<0.05). Co-IP experiments showed that MDM2 binds to p53 protein. Conclusions:MDM2 can exert a protective effect on HALI by inhibiting MLE-12 cell apoptosis through the p53/Bcl-2/Bax axis.

OBJECTIVE Cognitive deficit is a com-mon comorbidity in temporal lobe epilepsy(TLE)and that is not well controlled by current therapeutics.Currently,how epileptic seizure affects cognitive performance remains largely unclear.The subiculum is the major out-put of the hippocampus,which projects to entorhinal cor-tex and other more distinct brain regions.Physiologically,the subiculum codes spatial working memory and naviga-tion information including place,speed,and trajectory.Importantly,prior studies have noted the importance of the subiculum in the beginning,spreading,and generaliz-ing process of hippocampal seizure.How seizure-activated neurons in subiculum participate in cognitive impairment remains largely elusive.METHODS In this study,we sought to label the subicular seizure-activated c-fos+ neu-rons with a special promoter with enhanced synaptic activity-responsive element E-SARE in the subiculum,combined with chemogenetics and designer receptors exclusively activated by designer drugs(DREADDs),Ca2+ fiber photometry approaches,and behavioral tasks,to reveal the role of these neurons in cognitive impairment in epilepsy.RESULTS We found that chemogenetic inhibi-tion of subicular seizure-tagged c-fos+ neurons(mainly CaMK Ⅱ α+ glutamatergic neurons)alleviates seizure generalization and improves cognitive performance in the hippocampal CA3 kindling TLE model.While inhibition of seizure-labeled c-fos+ GABAergic interneuron shows no effect on seizure and cognition.As a comparison,che-mogenetic inhibition of the whole subicular CaMK Ⅱ α+ neuron impairs cognitive function in na?ve mice in basal condition.Notably,inhibition of subicular seizure-tagged c-fos+ neurons enhances the recruitment of cognition-responsive c-fos+ neurons via increasing neural excitability during cognition tasks.CONCLUSION Our results dem-onstrate that subicular seizure-activated c-fos+ neurons contribute to cognitive impairment in TLE,suggesting sei-zure-tagged c-fos+ neurons as the potential therapeutic target to alleviate cognitive impairment in TLE.

OBJECTIVE:
To analyze the clinical features and genotype of a child with Schmid type metaphyseal chondrodysplasia.
METHODS:
Clinical data of the child and her parents was collected. The child was subjected to high-throughput sequencing, and candidate variant was verified by Sanger sequencing of her family members.
RESULTS:
Whole exome sequencing revealed that the child has harbored a heterozygous c.1772G>A (p.C591Y) variant of the COL10A1 gene, which was not found in either of her parents. The variant was not found in the HGMD and ClinVar databases, and was rated as likely pathogenic based on the guidelines from the American College of Medical Genetics and Genomics (ACMG).
CONCLUSION
The heterozygous c.1772G>A (p.C591Y) variant of the COL10A1 gene probably underlay the Schmid type metaphyseal chondrodysplasia in this child. Genetic testing has facilitated the diagnosis and provided a basis for genetic counselling and prenatal diagnosis for this family. Above finding has also enriched the mutational spectrum of the COL10A1 gene.

Objective:To analyze the clinical adverse events of the first carbon ion therapy system in radiotherapy for cancer patients in China.Methods:A retrospective analysis was conducted on the clinical trial monitoring data of the carbon ion therapy system obtained by the Pharmacovigilance Center of Gansu Province. A descriptive study was conducted on the demographic characteristics, radiotherapy techniques, irradiation site and dose parameters, postoperative follow-up, and adverse event information of 46 tumor patients who received carbon ion therapy and participated in the clinical trial in Wuwei Cancer Hospital, Gansu Province from November 2018 to February 2019. Frequency and percentage were used to describe and analyze the occurrence of adverse events after carbon ion therapy for cancer patients in different groups. All subjects who received radiotherapy were grouped according to the treatment dose and fractionation method.Results:The median age of the 46 patients was 47 years old, and the male to female ratio was 30∶16. There were 15, 5, 8, 9, and 9 patients with head and neck, chest, abdomen, pelvic cavity, and limb spinal tumors, respectively. The total duration of radiotherapy was 2-4 weeks for 10-16 times. There were 246 adverse events in 45 cases, with an incidence of 98%. No severe adverse events occurred. The adverse events definitely related to carbon ion devices accounted for 19.1%, and no severe adverse events related to carbon ion devices occurred. According to the evaluation criteria of common terminology criteria for adverse events (CTCAE), the main adverse events were CTCAE grade 2 and below, with only 1 (2%) head and neck tumor patient (nasopharyngeal malignant tumor) experienced CTCAE grade 3 adverse events after treatment. In addition, 43 patients developed acute adverse reactions, with an incidence of 93%, mainly involving the skin, mucosa, eyes, ears, pharynx and esophagus, upper gastrointestinal tract, lower gastrointestinal tract (including pelvic cavity), lung, genitourinary tract, heart, central nervous system and hematology (white blood cells, platelets and neutrophils), etc. Conclusion:The adverse reactions of patients treated with the first carbon ion therapy system are mainly CTCAE grade 2 and below, and the clinical adverse events are mild and controllable.

Objective:To analyze the clinical characteristics and differences of inpatients who have been diagnosed with both cardiovascular and cerebrovascular diseases.The findings from this study will help medical professionals make informed decisions regarding diagnosis and treatment strategies for patients with coexisting cardiovascular and cerebrovascular diseases.Methods:This study included a total of 275 patients who were hospitalized in both the Neurology and Cardiology Departments of our hospital between January 2012 and December 2019.The study compared the treatment, hospitalization, and prognosis of the two departments using retrospective stratified analysis.Results:The majority of patients hospitalized in the Cardiology Department were diagnosed with circulatory system diseases(I00-I99), accounting for 92.0%(253 cases). In the Neurology Department, the main diagnoses were circulatory system diseases(I00-I99), nervous system diseases(G00-G99), symptoms and signs involving circulatory and respiratory systems, cognition, perception, emotional state and behavior(R00-R09, R40-R46), accounting for 69.8%(192 cases), 16.7%(46 cases)and 13.1%(36 cases), respectively.There was a significant difference in the distribution of diagnoses between the Cardiology and Neurology Departments( χ2=67.8, P<0.001). The Cardiology Department had a higher proportion of patients with 5 or more other diagnoses[153(55.6%) vs.59(21.5%)], while Neurology Department had a higher proportion of patients with 2-4 other diagnoses(64.0% vs.36.4%). When comparing the distribution of other diagnoses during hospitalization in the Cardiology Department, the proportion of patients with only one other diagnosis was higher in the first visit group of Neurology Department compared to those with two or more diagnoses, which was statistically significant( χ2=9.3, P=0.03). There was no statistical difference in hospitalization days between the two departments( χ2=2.2, P=0.14). Although there was a significant difference in patient outcomes, with a lower proportion of patients not recovering or dying in the Neurology Department( χ2=4.6, P=0.03), there was no significant difference in the interval between hospitalizations for the two groups(180 d, χ2=0.1, P=0.72; 90 d, χ2=1.8, P=0.18). Conclusions:The need for early prevention, diagnosis, and treatment of patients with both cardiovascular and cerebrovascular diseases is still a pressing concern.Exploring a combined diagnosis and treatment model for multiple diseases may prove useful in overcoming the limitations of the current single disease diagnosis and treatment approach.
