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.

Background::A phase II trial on recombinant human tenecteplase tissue-type plasminogen activator (rhTNK-tPA) has previously shown its preliminary efficacy in ST elevation myocardial infarction (STEMI) patients. This study was designed as a pivotal postmarketing trial to compare its efficacy and safety with rrecombinant human tissue-type plasminogen activator alteplase (rt-PA) in Chinese patients with STEMI.Methods::In this multicenter, randomized, open-label, non-inferiority trial, patients with acute STEMI were randomly assigned (1:1) to receive an intravenous bolus of 16 mg rhTNK-tPA or an intravenous bolus of 8 mg rt-PA followed by an infusion of 42 mg in 90 min. The primary endpoint was recanalization defined by thrombolysis in myocardial infarction (TIMI) flow grade 2 or 3. The secondary endpoint was clinically justified recanalization. Other endpoints included 30-day major adverse cardiovascular and cerebrovascular events (MACCEs) and safety endpoints.Results::From July 2016 to September 2019, 767 eligible patients were randomly assigned to receive rhTNK-tPA ( n = 384) or rt-PA ( n = 383). Among them, 369 patients had coronary angiography data on TIMI flow, and 711 patients had data on clinically justified recanalization. Both used a –15% difference as the non-inferiority efficacy margin. In comparison to rt-PA, both the proportion of patients with TIMI grade 2 or 3 flow (78.3% [148/189] vs. 81.7% [147/180]; differences: –3.4%; 95% confidence interval [CI]: –11.5%, 4.8%) and clinically justified recanalization (85.4% [305/357] vs. 85.9% [304/354]; difference: –0.5%; 95% CI: –5.6%, 4.7%) in the rhTNK-tPA group were non-inferior. The occurrence of 30-day MACCEs (10.2% [39/384] vs. 11.0% [42/383]; hazard ratio: 0.96; 95% CI: 0.61, 1.50) did not differ significantly between groups. No safety outcomes significantly differed between groups. Conclusion::rhTNK-tPA was non-inferior to rt-PA in the effect of improving recanalization of the infarct-related artery, a validated surrogate of clinical outcomes, among Chinese patients with acute STEMI.Trial registration::www.ClinicalTrials.gov (No. NCT02835534).

Objective Explore the comprehensive emotion adjustment pattern that combines non-contact physiological and psychological detection methods in fasting and low metabolism scenarios.This study aims to verify the accuracy of non-contact physiological and psychological detection algorithms and evaluate the effectiveness of multimodal emotion adjustment schemes for addressing negative emotional states such as depression and anxiety.Methods Deploy non-contact physiological and psychological detection algorithms and emotion adjustment plans to build a multimodal emotion adjustment system.Collect physiological and psychological data from volunteers participating in the 15-days complete fasting human low metabolism experiment of"Green Star Travel Ⅷ".Utilize finger clip oximeters and scales to verify the accuracy of existing non-contact physiological and psychological methods within the system.Design an emotion adjustment experiment featuring four groups:sound adjustment,acupoints adjustment,magnetism adjustment,and combination adjustment.Compare the volunteers'scale scores before and after the adjustments to verify the effectiveness of the system's emotion adjustment capabilities.Results The experimental results demonstrate that the average difference in the Bland-Altman plot for the non-contact heart rate detection model is ﹣0.497 bpm,with 95.3%of the error values falling within the 95%consistency interval.The non-contact psychological detection model achieved an accuracy rate of over 80%in identifying stress,anxiety,and depression,and an accuracy rate of over 70%in identifying fatigue and anger.Following emotion adjustment,the stress levels of the subjects significantly improved(P?

Objective In the future,during the landing and exploration of near-Earth planets(e.g.,Mars,Jupiter,etc.),astronauts may take the initiative to start fasting to reduce the amount of load;and it is even more likely that astronauts will take the initiative to fast in the process of manned deep-space exploration in the future,or they may enter a dormant low-metabolism state to save the amount of load to enable the spaceship to fly for a longer period,and to locate in a deeper and farther position.The ability of an individual to maintain cognitive ability and respond appropriately over a period in a long-term fasting state is important for survival.Therefore,the present study focused on investigating the effects of 15 days of complete fasting on dual cognitive control function and its neural mechanisms.Methods Twenty-four healthy volunteers were recruited to participate in the fasting experiment.Behavioral and electroencephalographic data from the AX-CPT Task were collected with event-related potentials(ERP)to assess the effects of 15 days of complete fasting on dual cognitive control in 16 volunteers.Results(1)Behavioral outcomes had significant main effects on response time[F(1,15)=99.41,P?

As China's manned space missions gradually develop towards long-term residence and deep space exploration,astronauts will face increasingly severe psychological challenges.As a psychological adjustment method involving multiple disciplines such as music,psychology,and medicine,music therapy has the advantages of being convenient to implement,cost-effective,and highly personalized.This paper integrates the concept of music therapy and explores the research progress of music therapy in regulating psychological states in aspects such as physiology,emotional regulation,cognitive ability,and interpersonal relationships.Combined with the mechanism of action of music therapy and the practical situation in the field of manned spaceflight,it aims at the future development trends and problems to be solved,to construct a music therapy system for astronauts during on-orbit flight and ground daily training.This will help astronauts achieve healthy physical and mental development and promote the completion of missions.

Objective:To observe the effect of lipopolysaccharide (LPS) induced conditioned medium of alveolar epithelial cells on the inflammatory response and cell damage of vascular endothelial cells, and explore its mechanism.Methods:The LPS induced type Ⅱ alveolar epithelial cells (A549) conditioned medium was used as a stimulus to induce human umbilical vein endothelial cells (HUVEC) damage. The cell counting kit-8 (CCK-8) was used to detect the effect of 0% (blank group), 12.5%, 25%, 50%, 75% and 100% A549 cell conditioned medium cultured for 6, 12, 24 and 48 hours on the cell viability of HUVEC. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of inflammatory factors [interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α)] and vasoactive substances [vascular endothelial growth factor (VEGF), endothelin-1 (ET-1)] in the supernatant. Phalloidin staining was used to observe the effects of A549 cells conditioned medium on cell morphology. The expressions of protein kinase B/nuclear factor-κB (AKT/NF-κB) pathway in HUVEC induced by conditioned medium was detected by Western blotting.Results:Compared with the blank group, A549 cells conditioned medium with concentrations of 12.5%, 25%, and 50% had no significant effects on cell viability of HUVEC after 6, 12, and 24 hours, but the activity of HUVEC decreased significantly after 48 hours. Therefore, 12.5%, 25%, 50% A549 cell conditioned medium stimulated for 24 hours was selected as the induction condition for follow-up experiments. Compared with the blank group, the level of IL-6 was significantly increased in 12.5% and 50% conditioned medium groups (ng/L: 2?438.95±64.89, 3?036.41±96.69 vs. 1?736.75±20.99, both P < 0.05), the level of TNF-α was significantly increased in 12.5% and 25% conditioned medium groups (ng/L: 174.08±11.09, 81.37±8.17 vs. 50.03±0.26, both P < 0.01), the levels of VEGF and ET-1 were significantly increased in 12.5%, 25% and 50% conditioned medium groups [VEGF (ng/L): 173.60±41.44, 192.49±12.38, 318.89±27.90 vs. 66.68±19.65; ET-1 (ng/L): 54.88±1.37, 36.69±0.29, 24.07±0.73 vs. 10.67±0.25, all P < 0.01]. Phalloidin staining showed that HUVEC induced by 25% A549 cells conditioned medium were irregular in shape, uneven in size, disordered in arrangement, widened in gap, dense and unclear in microfilament structure and serrated in cell membrane. Furthermore, the average fluorescence intensity of 25% conditioned medium group significantly increased compared to the blank group (67?205.60±3?430.40 vs. 56?272.67±7?650.95, P < 0.05). Western blotting showed that compared with the blank group, the expression of HUVEC cells phosphonated inhibitor α of NF-κB (p-IκBα) was significantly decreased in the 12.5%, 25%, and 50% conditioned medium groups (p-IκBα/IκBα: 0.38±0.08, 0.67±0.12, 0.31±0.07 vs. 1.00±0.00, all P < 0.01), the expressions of phosphonated-AKT (p-AKT) and VEGF were significantly increased (p-AKT/AKT: 1.50±0.18, 1.42±0.27, 1.61±0.14 vs. 1.00±0.00, VEGF/GAPDH: 1.37±0.10, 1.53±0.22, 1.40±0.12 vs. 1.00±0.00, all P < 0.05), the expression of phosphonated NF-κB p65 (p-P65) was significantly increased in the 25% conditioned medium group (p-P65/P65: 1.45±0.14 vs. 1.00±0.00, P < 0.05). Conclusion:LPS induced conditional culture medium of alveolar epithelial cells induced endothelial cell damage via activating AKT/NF-κB pathway.

N6-methyladenosine (m6A) is one of the most common post-transcriptional modifications of eukaryotic mRNA. The m6A modification accelerates mRNA metabolism and translation, and plays an important role in cell differentiation, embryonic development and stress response. As a reversible epigenetic modification, m6A modification plays an important role in many physiological and pathological processes. The m6A modification is closely related to the occurrence and progression of respiratory diseases, and the m6A modification regulatory factor may be a potential target for regulating respiratory diseases. This article reviews the role of m6A modification in the development of respiratory diseases such as lung cancer, acute lung injury (ALI), asthma, pulmonary fibrosis, and chronic obstructive pulmonary disease (COPD). The purpose of m6A modification is to provide a reference for the pathogenesis of respiratory diseases and the study of targets.

Today, medication remains a fundamental guarantee of long-term improvement in the quality of life for patients with Parkinson′s disease (PD). Since the 1960s, compound levodopa has been used to treat PD, and has been proved to be the most effective drug for the treatment of PD, which can not only improve the motor symptoms of PD patients, but also improve the quality of life. However, there are still some misunderstandings about the use of compound levodopa in clinical practice. With the progression of the disease, the related motor complications caused by its treatment have caused certain troubles to both clinicians and patients. This paper reviewed the results of related clinical studies at home and abroad, as well as guidelines and consensus, and carried out a comprehensive and systematic analysis and summary of the pharmacological characteristics of compound levodopa, evidence-based research evidence, clinical standard use, etc, combined with China′s national conditions and clinical practice, hoping to standardize the reasonable clinical application of compound levodopa and provide drug reference for the majority of clinical workers.

Objective:The purpose of this study was to investigate the evaluating value of modified critical care ultrasonic examination(M-CCUE) scheme for the etiological diagnosis of shock in ICU patients.Methods:The prospective study collected relevant clinical data of various shock patients admitted to the Department of Intensive Care Medicine, Henan Provincial People's Hospital from May 2020 to July 2021, including hemodynamic、blood indicators、organ/tissue perfusion and prognostic evaluation indicators.All selected patients completed the initial M-CCUE assessment within 30 minutes, were scored according to the M-CCUE score system and related data results were analyzed.Results:Ninety-three patients were included in this study,Two of them were not completed the M-CCUE assessment due to emergency treatment immediately after entering our department, and five were excluded due to inconsistent ultrasound judgments by the two physicians. In the end, a total of 86 patients were enrolled in the group. In patients applied with M-CCUE scheme,time to preliminary diagnosis and final diagnosis were (13.02±3.15)min and (67.70±20.20)min respectively, the accuracy of diagnosis was 83.7%. Among them, distributed shock accounted for 60.4%, hypovolemic shock accounted for 25.6%, cardiogenic shock and obstructive shock accounted for 3.5%, and mixed shock accounted for 7%; MCS is (13.27±4.91), M-CCUE scheme had the high sensitivity and specificity for the diagnosis of distributed shock (sensitivity 91.2%, specificity 93.9%), hypovolemic shock (sensitivity 96.0%, specificity 96.7%), cardiogenic shock (sensitivity 85.7%, specificity 98.7%) and obstructive shock (sensitivity 60.0%, specificity 100%); MCS has a good positive correlation with APACHEⅡ score ( r=0.861, P<0.001), and has no correlation with ICU cost ( r=0.012, P=0.915). There is no significant difference in MCS between the 28d death group and the recovery group ( P=0.391). Conclusions:For shock patients admitted to ICU with unknown etiology, the initial diagnosis of the cause of the M-CCUE program takes less time, has a higher correct diagnosis rate, sensitivity and specificity, and its quantitative evaluation results can predict the patient's criticality.
