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 changes in cerebral blood flow caused by mandibular retrusion,as well as the impact and potential mechanisms on stroke recovery.Methods 6-week-old SD male rats were selected as experi-mental subjects.The metal cannula was bonded to the rat maxillary incisor for one week,forcing mandibular retru-sion(MR).Cerebral blood flow was detected by laser speckle imaging.Cognitive function was detected by the Morris water.Then,the stroke model was constructed in MR rats by using the middle cerebral artery occlusion(MCAO)method for one week.Meanwhile,metal cannulae were then removed in rats to restore the lower jaw's position(MCAO RO),serving as a positive control group.Consequently,rats were randomly divided into the fol-lowing groups:Sham groups,MCAO groups,MCAO MR groups,and MCAO RO groups.Neurological recovery was assessed through the modified neurological severity score(mNSS).The area of cerebral infarction was evalua-ted by using triphenyltetrazolium(TTC)staining.The changes in nerve cells were observed by using hematoxylin eosin(HE)staining.The protein expression level of vascular endothelial growth factor(VEGF)was detected by immunohistochemistry.The protein expression levels of platelet-endothelial cell adhesion molecule(CD31),sirtuin 6(SIRT6),and thioredoxin interaction protein(TXNIP)were detected by Western blot.The mRNA expression levels of SIRT6,TXNIP,and VEGF were determined by qRT-PCR.Microglia activation marker molecule 1(IBA-1)was detected by immunofluorescence.Resluts Because of mandibular retrusion,laser speckle showed de-creased cerebral blood flow,and the water maze showed decreased cognitive function.Compared to other groups,MCAO MR showed a larger ischemic area in TTC staining,while HE staining and neurological scoring showed poo-rer neurological function recovery.Western blot and qRT-PCR showed that the MCAO MR group inhibited the mR-NA and protein expression levels of SIRT6,upregulated the mRNA and protein expression levels of TXNIP,and in-creased the activation of microglia.Conclusion Mandibular retrusion reduces cerebral blood flow and alters cogni-tive function in rats.Mandibular retrusion inhibits recovery in stroke through the SIRT6/TXNIP axis.

Objective To predict the risk of in-hospital death in patients with chronic heart failure(CHF)complicated by lung infections using interpretable machine learning.Methods The clinical data of 1415 patients diagnosed with CHF complicated by lung infections were obtained from the MIMIC-IV database.According to the pathogen type,the patients were categorized into bacterial pneumonia and non-bacterial pneumonia groups,and their risks of in-hospital death were compared using Kaplan-Meier survival curves.Univariate analysis and LASSO regression were used to select the features for constructing LR,AdaBoost,XGBoost,and LightGBM models,and their performance was compared in terms of accuracy,precision,F1 value,and AUC.External validation of the models was performed using the data from eICU-CRD database.SHAP algorithm was applied for interpretive analysis of XGBoost model.Results Among the 4 constructed models,the XGBoost model showed the highest accuracy and F1 value for predicting the risk of in-hospital death in CHF patients with lung infections in the training set.In the external test set,the XGBoost model had an AUC of 0.691(95%CI:0.654-0.720)in bacterial pneumonia group and an AUC of 0.725(95%CI:0.577-0.782)in non-bacterial pneumonia group,and showed better predictive ability and stability than the other models.Conclusion The overall performance of the XGBoost model is superior to the other 3 models for predicting the risk of in-hospital death in CHF patients with lung infections.The SHAP algorithm provides a clear interpretation of the model to facilitate decision-making in clinical settings.

Objective To investigate the dietary patterns of rural residents in the high-incidence areas of esophageal cancer (EC), and to explore the clustering and influencing factors of risk factors associated with high-incidence characteristics. Methods A special structured questionnaire was applied to conduct a face-to-face survey on the dietary patterns of rural residents in Yanting county of Sichuan Province from July to August 2021. Univariate and multivariate logistic regression models were used to analyze the influencing factors of risk factor clustering for EC. Results There were 838 valid questionnaires in this study. A total of 90.8% of rural residents used clean water such as tap water. In the past one year, the people who ate fruits and vegetables, soybean products, onions and garlic in high frequency accounted for 69.5%, 32.8% and 74.5%, respectively; the people who ate kimchi, pickled vegetables, sauerkraut, barbecue, hot food and mildew food in low frequency accounted for 59.2%, 79.6%, 68.2%, 90.3%, 80.9% and 90.3%, respectively. The clustering of risk factors for EC was found in 73.3% of residents, and the aggregation of two risk factors was the most common mode (28.2%), among which tumor history and preserved food was the main clustering pattern (4.6%). The logistic regression model revealed that the gender, age, marital status and occupation were independent influencing factors for the risk factors clustering of EC (P<0.05). Conclusion A majority of rural residents in high-incidence areas of EC in Yanting county have good eating habits, but the clustering of some risk factors is still at a high level. Gender, age, marital status, and occupation are influencing factors of the risk factors clustering of EC.

To scientifically evaluate the intervention effect of Chinese medicine preventive administration(combined use of Huo-xiang Zhengqi Oral Liquid and Jinhao Jiere Granules) on community population in the case of coronavirus disease 2019(COVID-19), a large cohort, prospective, randomized, and parallel-controlled clinical study was conducted. Total 22 065 subjects were included and randomly divided into 2 groups. The non-intervention group was given health guidance only, while the traditional Chinese medicine(TCM) intervention group was given two coordinated TCM in addition to health guidance. The medical instructions were as follows. Huoxiang Zhengqi Oral Liquid: oral before meals, 10 mL/time, 2 times/day, a course of 5 days. Jinhao Jiere Granules: dissolve in boiling water and take after meals, 8 g/time, 2 times/day, a course of 5 days, followed up for 14 days, respectively. The study found that with the intake of medication, the incidence rate of TCM intervention group was basically maintained at a low and continuous stable level(0.01%-0.02%), while the non-intervention group showed an overall trend of continuous growth(0.02%-0.18%) from 3 to 14 days. No suspected or confirmed COVID-19 case occurred in either group. There were 2 cases of colds in the TCM intervention group and 26 cases in the non-intervention group. The incidence of colds in the TCM intervention group was significantly lower(P<0.05) than that in the non-intervention group. In the population of 16-60 years old, the incidence rate of non-intervention and intervention groups were 0.01% and 0.25%, respectively. The difference of colds incidence between the two groups was statistically significant(P<0.05). In the population older than 60 years old, they were 0.04% and 0.21%, respectively. The incidence of colds in the non-intervention group was higher than that in the intervention group, but not reaching statistical difference. The protection rate of TCM for the whole population was 91.8%, especially for the population of age 16-60(95.0%). It was suggested that TCM intervention(combined use of Huoxiang Zhengqi Oral Liquid and Jinhao Jiere Granules) could effectively protect community residents against respiratory diseases, such as colds, which was worthy of promotion in the community. In addition, in terms of safety, the incidence of adverse events and adverse reactions in the TCM intervention group was relatively low, which was basically consistent with the drug instructions.

Objective To discuss the advantages of postoperative early ambulation for patients after high-viscosity bone cement injection treatment for osteoporotic vertebral compression fracture.Methods A total of 42 patients with osteoporotic vertebral compression fracture were divided into the study group (n=21)and the control group (n=21).High-viscosity bone cement injection was used to perform percutaneous vertebroplasty for the patients in the study group,while low-viscosity bone cement injection was adopted to complete percutaneous vertebroplasty for the patients in the control group.The patients of the study group were asked to get out of bed in 4 hours after vertebroplasty and to do off-bed activity in 8 hours after vertebroplasty,while the patients of the control group were asked to get out of bed in 12 hours after vertebroplasty and to do off-bed activity in 24 hours after vertebroplasty.CT reexamination was performed within 3 days after vertebroplasty to observe the paravertebral leakage and the cement distribution in vertebrae.The visual analogue scale (VAS),the ability score of daily life activy (Barthel),the risk score of pressure skin ulcer (Braden) and the risk rating of deep venous thrombosis were used to evaluate the clinical effectiveness for both groups.Results The procedure of vertebroplasty was successfully accomplished in all patients of both groups.No statistically significant differences in VAS score and in Barthel score at 24 hours and 7 days after vertebroplasty existed between the two groups (P＞0.05).Eight days after vertebroplasty,the differences in Barthel score,Braden score and the risk rating of deep venous thrombosis between the two groups were statistically significant (P＜0.05),although the difference in VAS score between the two groups was not statistically significant.Conclusion In treating osteoporotic vertebral compression fracture by using high-viscosity bone cement injection,postoperative early ambulation can effectively improve the patient's daily activities,reduce the risk of the formation of pressure skin ulcer and deep vein thrombosis,thus,reduce the nursing workload for both nurses and patient's family members.(J Intervent Radiol,2017,26:749-752).

OBJECTIVE: To analyze the clinical characteristics, imaging features, pathological findings, treatment and prognosis of the extrapleural solitary fibrous tumor (EPSFT) in nose, and then to improve the quality of diagnosis and treatment of EPSFT. METHOD: Clinical data of two patients with EPSFT were collected in recent 2 years. All the information, including clinical symptoms, imaging characteristics, blood routine, serum biochemical, treatment options, pathological immunohistochemical findings, and following-up results were reported and analyzed, and the clinical features of EPSFT in the nose were summarized with review of the literature. RESULT: (1) The main clinical characteristics were nasal obstructive and epistaxis. (2)There were no imaging differences essentially between EPSFT and other tumors in nasal cavity. In terms of enhancement CT scanning, the image manifestations of EPSET were similar to that of hemangioma to a certain degree in nasal cavity. (3) Routine blood and serum biochemical test were normal in the patients with EPSFT in the nose. (4)Confirmed diagnosis mainly depended on pathological and immunohistochemical findings. (5) These two patients underwent surgical treatment, and the tumors were en bloc resected, and were in full recovery. Follow-up time is 2 years in one case and the other one is 1 year. No recurrence or metastasis were found in these two patients. CONCLUSION DSA and vascular embolism is recommended before surgical treatment in some patients. En bloc resection is the preferred treatment option with definite curative effect for the patients with EPSFT in nose, and the prognosis is favorable.

OBJECTIVE: To analyze the clinical manifestations of three cases of cervical necrotizing fasciitis caused by klebsiella pneumoniae and to analyze the published articles concerning the relationship between invasive klebsiella syndrome and necrotizing fasciitis in Chinese Mainland. METHOD: We have retrospectively analyzed three cases of cervical necrotizing fasciitis caused by klebsiella pneumoniae treated in our department between 2003 and 2012. We also reviewed the Chinese-language scientific literature included in the WanFang data by searching with the following key words: necrotizing fasciitis, klebsiella pneumoniae and liver abscess. RESULT: These patients recovered uneventfully without obvious complications or disseminated infection foci. Sporadic cases of invasive klebsiella syndrome were reported without necrotizing fasciitis involvement in Chinese Mainland. CONCLUSION Cervical necrotizing fasciitis caused by klebsiella pneumoniae may give rise to disseminated infection but there has been no such case report in Chinese Mainland.

OBJECTIVE: To explore the causes, clinical features, diagnosis and treatment of cervical extensive necrotizing fasciitis, a rare clinical occurrence, and to improve the clinical recognition and appreciation of it. METHOD: Two cases of cervical extensive necrotizing fasciitis were studied and relevant literatures were reviewed. The causes, clinical manifestation, experience of diagnosis and treatment were summarized. RESULT: One of two cases was secondary to foreign body of hypopharynx, and the other with unknown cause. Apathy, crepitation and diffuse swelling and rubor following with abscess formation on the neck are main characteristics. Mixed synergistic infection was confirmed by drainage culturing. All two cases were treated actively by large dosage and effective broad spectrum antibiotics, and sustaining therapy and surgical treatment, including local incision and drainage, aggressive surgical debridement and tracheotomy. CONCLUSION Cervical extensive necrotizing fasciitis is a potentially life-threatening soft tissue infection. The keys of successful treatment were early diagnosis and surgical intervention. Rational antibiotics application and systemic supporting therapeutics were also recommended.
