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 study the clinical manifestations and genetic characteristics of neonatal-onset primary mitochondrial disease (PMD) caused by nuclear gene mutations.Methods:From May 2020 to March 2022, the clinical data, genetic results and follow-up information of neonates with PMD admitted to the Department of Neonatology of our two hospitals were retrospectively analyzed.Results:A total of 4 patients were enrolled, all with hyperlactatemia and metabolic acidosis. In case 1, the fetal cranial MRI showed agenesis of corpus callosum. In case 2, echocardiography after birth indicated hypertrophic cardiomyopathy. Whole exome sequencing found the following mutations: EARS2 nuclear gene c.1294C>T and c.971G>T variants, COA6 nuclear gene c.411_412insAAAG variant, ACAD9 nuclear gene c.1278+1G>A and c.895A>T variants, FOXRED1 nuclear gene c.1054C>T and c.3dup variants. Mitochondrial second-generation sequencing and multiplex ligation-dependent probe amplification showed no abnormalities. Cases 1 and 3 died during the neonatal period. Case 2 died at 2-year-and-2-month of age. Case 4 was followed up to 1 year of age with developmental delay.Conclusions:The main phenotypes of neonatal-onset PMD caused by nuclear gene mutations are hyperlactatemia, refractory metabolic acidosis and cardiomyopathy, which have a poor prognosis. Proactive genetic tests are helpful for early diagnosis.

Objective:To analyze the differentially expressed genes of human respiratory syncytial virus (RSV) subtype A genotype ON1, a predominant genotype in Beijing, after infecting A549 cells using transcriptomic sequencing, and provide potential targets for RSV prevention and treatment.Methods:A local strain (61397-ON1) identified by whole-genome sequencing as ON1 genotype of RSV subtype A was selected to infect A549 cells. Total mRNA was extracted, and the differentially expressed genes in infected and uninfected A549 cells were screened by transcriptomic sequencing. GO analysis and KEGG pathway analysis were performed. Besides, six genes with differential expression ratio greater than two times were randomly selected for qRT-PCR verification.Results:There were 1 632 differentially expressed genes between infected and uninfected A549 cells, of which 807 genes were up-regulated and 825 genes were down-regulated. The differentially expressed genes were mainly involved in immune response-related biological processes such as cytokine response and positive regulation of MAPK cascades, and were enriched in MAPK signaling pathway, NOD-like receptor signaling pathway, p53 signaling pathway, TNF signaling pathway, IL-17 signaling pathway and NF-κB signaling pathway. The results of qRT-PCR for six differentially expressed genes were consistent with the trend of transcriptome data.Conclusions:The differentially expressed genes of RSV A subtype ON1 genotype after infecting A549 cells are mainly involved in cytokine response and immune-related signaling pathways. This study provides basic data for further study of the molecular mechanism of RSV infection and the development of prevention and treatment strategies.

This paper summarized Professor ZHOU Zhongying's experience in differentiating and treating hepatitis and liver cirrhosis from deficiency and excess. It is considered that the pathogenesis of hepatitis and liver cirrhosis belongs to deficiency in root and excess in branch， with depletion of liver， spleen and kidney as the root， and constraint and bind of damp-heat and stasis toxin as the branch. Moreover， mutual cause and promotion between deficiency and excess leads to the disease. For general principle of treatment， it is recommended to clear and transform pathogenic excess， supplement deficiency and rectify the healthy qi. In the early stage of hepatitis and cirrhosis， excess pathogen hyperactivity is the main manifestation， which can be treated by clearing and transforming damp-heat and stasis toxin， supplemented by regulating spleen and stomach， with modified Yinchenhao Decoction （茵陈蒿汤） and Biejiajian Pill （鳖甲煎丸）. In the middle and late stages， cases with deficiency-excess complex were more common， which should be treated by clearing damp-heat and stasis toxin， regulating and supplementing liver-spleen-kidney， using medicinals with the function of clearing heat and dispelling damp， dissolving stasis and resolving toxins to treat the branch. Moreover， Liujunzi Decoction （六君子汤）， Yiguan Decoction （一贯煎）plus Erzhi Pill （二至丸） and Buzhong Yiqi Decoction （补中益气汤） modifications are suggested respectively in correspondence to the different kinds of root deficiency including irregular liver and spleen， liver and kidney yin deficiency， and liver-spleen-kidney deficiency.

Objective:To analyze identification of copper death gene related subtypes,construction of prognosis model and influence of immune infiltration in osteosarcoma(OS)on basis of copper death gene.Methods:Survival and prognosis of OS associated copper death gene were analyzed combining by TARGET and GEO database.OS was divided into different subtypes of copper death by consistent clustering method.SSGSEA was used to analyze difference of immune cells in classification of copper death.Setting P value= 0.05 and q value=0.05,GO and KEGG enrichment analysis were performed on differential genes of copper death typing.Prognosis model was constructed according to results of Lasso regression analysis and cross validation,risk assessment analysis and ROC curve were used to evaluate accuracy of model prediction.Combined with clinical characteristics,nomograms were constructed to predict survival time of patients,and risk differences were analyzed.Immune cell infiltration and tumor microenvironment analysis were performed on OS samples."pRRophetic"package in R software was used to analyze drug sensitivity of OS samples.Results:FDX1,GLS,DLAT and PDHB as high-risk genes for OS prognosis were identified.According to copper death classification of OS samples,OS could be divided into two types:CRGclusterA and CRGclusterB.CRGclusterA was associated with Th2 cells,and CRGclusterB was associated with Th1 cells.Most OS copper death genes were highly expressed in CRGclusterA.Immune cell infiltration analysis results showed that γδ T cells,resting mast cells and resting dendritic cells were positively correlated with risk score,while CD8 T cells were negatively correlated with risk score.Drug sensitivity analysis showed that OS showed higher sensitivity to Elesclomol and GW.441756.Conclusion:Two subtypes of CRGclusterA and CRGclusterB are identified in this study.Four high-risk prognostic genes FDX1,GLS,DLAT and PDHB are identified,providing new insights into prognostic evaluation and immunotherapy target candidates for OS.

AIM:One of the important characteristics of the occurrence and development of triple-negative breast cancer(TNBC)is dysregulated cell metabolism.The aim of this study is to investigate the mechanism of pyruvate dehydrogenase E1 subunit alpha 1(PDHA1),a key enzyme component in aerobic glycolysis,affecting the proliferation,metastasis and invasion of TNBC.METHODS:(1)The expression levels of PDHA1 in breast cancer tissues and adja-cent tissues were analyzed by UALCAN database,KM-plotter database,Gene MANIA database and TCGA database.The expression of PDHA1 was compared according to tumor pathological stage,subtype classification and breast cancer bio-markers.The function of PDHA1 in TNBC was explored by gene enrichment analysis.(2)Immunohistochemistry assays were used to detect the expression of PDHA1 in human TNBC tissue and adjacent tissue samples.(3)Stable PDHA1 knockout and PDHA1 rescue TNBC MDA-MB-231 cells were constructed.The proliferation of MDA-MB-231 cells was de-tected by colony formation assay and cell counting assay.The regulatory effect of PDHA1 on the invasion and migration of MDA-MB-231 cells was detected by in vitro scratch assay and Transwell migration assay.RESULTS:Database analysis showed that the group with high PDHA1 expression in breast cancer had shorter survival and worse prognosis.In clinical specimens,the expression of PDHA1 in cancer tissues was higher than that in adjacent normal tissues.Knockout of PDHA1 inhibited the proliferation,metastasis,invasion and epithelial-mesenchymal transition of MDA-MB-231 cells.CONCLUSION:PDHA1 is overexpressed in TNBC,and it promotes cell proliferation and facilitates TNBC metastasis through the epithelial-mesenchymal transition pathway.

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 assess the predictive value of a combined multiclassification model for computed tomography(CT)in the patholo-gical analysis of ground-glass nodules(GGN).Methods:Pulmonary GGN lesions that were pathologically confirmed as invasive adenocar-cinoma(IAC),minimally invasive adenocarcinoma(MIA),adenocarcinoma in situ(AIS),and preinvasive lesions(PILs),were collected from pa-tients who were treated at The First Affiliated Hospital of Xinxiang Medical University between February 2019 and March 2023.A total of 324 nodules were retrospectively collected from 285 patients,and divided into three groups:infiltrating IAC,MIA,and PILs.Radiomics and clinical-CT features were selected through recursive feature elimination and univariate Logistic regression.Seven models were constructed using Logistic regression(LR),support vector machine(SVM),random forest(RF),and integrative learning(stacking).Results:The hybrid model combining clinical-CT-radiomics features and an integrative strategy showed superior predictive performance,with an accuracy of 0.791,precision of 0.788,specificity of 0.857,recall of 0.790,and F1-Score of 0.789.Conclusions:The multiclassification joint model based on CT-radiomics is effective in predicting pathological classification of pulmonary GGNs.This model aids in accurate imaging diagnosis and can provide a basis for optimizing treatment plans.

Emaciation is a common physical condition in clinical practice,often accompanied by symptoms related to"excessive fire in thin people".Insufficient yin-qi is the main physiological and pathological basis of emaciation,and excessive dryness-heat is the secondary manifestation.The disease involves five viscera,with the spleen as the core.The principle of treatment is to nourish yin-qi as the main method,and to dissipate stagnant heat as the auxiliary method.Specifically,it includes two aspects:treating the root cause and treating the symptoms.Treating the root cause should nourish yin-qi to improve the"emaciation"constitution,and treating the symptoms should dissipate stagnant heat to eliminate the"excessive fire"state.The importance of the two should be determined ac-cording to the severity and urgency of the excessive fire.Clinically,the addition and subtraction of medicinal ingredients are made ac-cording to factors such as the urgency of the root cause and symptoms,the state of emaciation and the ability to eat,the degree of defi-ciency or excess of fire-heat,the pathogenesis of the disease,and the season.

Objective:This study aims to establish an early warning diagnosis model for acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and to provide a simple, rapid, and accurate auxiliary diagnosis basis for clinical practice.Methods:The sample bank of subjects (patients admitted to the Eighth Medical Center of the PLA General Hospital from September 10, 2021, to July 25, 2023) was constructed, including the model establishment cohort [SCOPD group 49, 42 males and 7 females, (69.71±11.16) years old; AECOPD group 53, 49 males and 4 females, (72.60±10.19) years old] and the model validation cohort [SCOPD group 35, 28 males and 7 females, (69.97±10.40) years old; AECOPD group 35, 33 males and 2 females, (71.43±9.67) years old]. Fasting peripheral blood samples were collected, and the expression levels of IL-5, IL-17A, and IFN-α were detected by flow cytometry. Different expression levels were analyzed by Mann-Whitney U test. Binary logistic regression analysis was used to screen the related risk factors of COPD patients in acute exacerbation. The diagnostic efficacy of the model was evaluated by the receiver operating characteristic (ROC) curve.Results:The levels of IL-5 [1.64 (0.60, 2.86) pg/ml], IL-17A [1.42 (0.88, 2.29) pg/ml], and IFN-α [0.91 (0.59, 1.81) pg/ml] in the SCOPD group were significantly decreased compared with the AECOPD group IL-5 [4.68 (2.34, 9.40) pg/ml, Z=-5.033, P<0.001], IL-17A [2.33 (1.59, 4.62) pg/ml, Z=-3.919, P<0.001], IFN-α [2.83 (0.91, 3.75) pg/ml, Z=-4.127, P<0.01] in the cohort of model establishment. The results of binary logistic regression analysis between SCOPD and AECOPD groups showed that IL-5, IL-17A, and IFN-α were independent risk factors for acute exacerbation of patients with COPD ( P<0.05). And the regression equation is Y=-2.861+0.364×IL-5+0.385×IL-17A+0.445×IFN-α. The AUC value of IL-5, IL-17A, IFN-α and combined detection was 0.866 ( P<0.001). Compared to the SCOPD group and the AECOPD group in the cohort of model validation, the receiver operating characteristic (ROC) curve showed that the combined model of three (AUC=0.858, P<0.001) could be used to diagnose the AECOPD. And the Kappa value was 0.773( P<0.05). Conclusion:The combined detection of IL-5, IL-17A, and IFN-α has high diagnostic efficacy for patients with acute exacerbation of COPD. This method provides a new potential tool for the clinical diagnosis of AECOPD and has the value of further exploration and optimization, promotion, and application.
