Objective:To describe a novel approach for intractable Meniere's disease exclusively through a transcanal endoscopic ear surgery(TEES). Methods:This retrospective chart review included patients with intractable Menière's disease who underwent endoscopic transcanal labyrinthectomy in the Department of Otolaryngology Head and Neck Surgery, Guangxi Hospital Division, First Affiliated Hospital, Sun Yat-sen University, between February 2023 and October 2024. The first 70-year-old woman and the other 67-year-old woman, who underwent multiple conservative treatment and chemical labyrinthectomy during outpatient and hospitalization, had frequent vertigo, tinnitus and severe sensorineural deafness. The TEES approach provided a wide exposure of the oval window. The incus and the stapes were removed, expanded the oval window. The perilymph was suctioned, The saccule, utricule, macula utriculi and macula sacculi were removed. The ampulla tissue of the three semicircular canal were destroyed with the right-angle crochet. The oval window was obliterated using the perichondrium of the tragal cartilage and cartilage. Results:Two patients underwent endoscopic transcanal labyrinthectomy, and no intraoperative or postoperative complications were observed. Vertigo was controlled in 2 patients during the follow-up of 6 to 12 months. Two patients complained of total hearing loss after surgery. Conclusion:Even though this study presents a limited number of cases, endoscopic transcanal labyrinthectomy is a promising, safe, and effective procedure in selected cases. Additional studies are needed to determine the risk-benefit profile of this technique.

Metabolomics covers a wide range of applications in life sciences, biomedicine, and phytology. Data acquisition (to achieve high coverage and efficiency) and analysis (to pursue good classification) are two key segments involved in metabolomics workflows. Various chemometric approaches utilizing either pattern recognition or machine learning have been employed to separate different groups. However, insufficient feature extraction, inappropriate feature selection, overfitting, or underfitting lead to an insufficient capacity to discriminate plants that are often easily confused. Using two ginseng varieties, namely Panax japonicus (PJ) and Panax japonicus var. major (PJvm), containing the similar ginsenosides, we integrated pseudo-targeted metabolomics and deep neural network (DNN) modeling to achieve accurate species differentiation. A pseudo-targeted metabolomics approach was optimized through data acquisition mode, ion pairs generation, comparison between multiple reaction monitoring (MRM) and scheduled MRM (sMRM), and chromatographic elution gradient. In total, 1980 ion pairs were monitored within 23 min, allowing for the most comprehensive ginseng metabolome analysis. The established DNN model demonstrated excellent classification performance (in terms of accuracy, precision, recall, F1 score, area under the curve, and receiver operating characteristic (ROC)) using the entire metabolome data and feature-selection dataset, exhibiting superior advantages over random forest (RF), support vector machine (SVM), extreme gradient boosting (XGBoost), and multilayer perceptron (MLP). Moreover, DNNs were advantageous for automated feature learning, nonlinear modeling, adaptability, and generalization. This study confirmed practicality of the established strategy for efficient metabolomics data analysis and reliable classification performance even when using small-volume samples. This established approach holds promise for plant metabolomics and is not limited to ginseng.

Acute respiratory distress syndrome (ARDS) is a common respiratory emergency, but current clinical treatment remains at the level of symptomatic support and there is a lack of effective targeted treatment measures. Our previous study confirmed that inhalation of hydrogen gas can reduce the acute lung injury of ARDS, but the application of hydrogen has flammable and explosive safety concerns. Drinking hydrogen-rich liquid or inhaling hydrogen gas has been shown to play an important role in scavenging reactive oxygen species and maintaining mitochondrial quality control balance, thus improving ARDS in patients and animal models. Coral calcium hydrogenation (CCH) is a new solid molecular hydrogen carrier prepared from coral calcium (CC). Whether and how CCH affects acute lung injury in ARDS remains unstudied. In this study, we observed the therapeutic effect of CCH on lipopolysaccharide (LPS) induced acute lung injury in ARDS mice. The survival rate of mice treated with CCH and hydrogen inhalation was found to be comparable, demonstrating a significant improvement compared to the untreated ARDS model group. CCH treatment significantly reduced pulmonary hemorrhage and edema, and improved pulmonary function and local microcirculation in ARDS mice. CCH promoted mitochondrial peripheral division in the early course of ARDS by activating mitochondrial thioredoxin 2 (Trx2), improved lung mitochondrial dysfunction induced by LPS, and reduced oxidative stress damage. The results indicate that CCH is a highly efficient hydrogen-rich agent that can attenuate acute lung injury of ARDS by improving the mitochondrial function through Trx2 activation.

Objective:To investigate the value of using ultrasound excited contrast agents to assess extracorporeal hydrostatic pressure on the basis of ultrasound contrast imaging.Methods:An extracorporeal hydrostatic pressure evaluation system was established. The changes in contrast intensity was first evaluated for the same concentration of microbubble contrast agent at ambient pressures of 20, 25, 30, 35, 40, and 45 cmH 2O. Contrast agents with the same initial intensity were placed at different pressures for 1 s, 3 s, and 5 s, and the percentage change in contrast agent intensity was analyzed to select the optimal excitation time. Finally, the contrast agent at different pressures was stimulated using an acoustic excitation device, and correlation analysis was performed using the Pearson product moment correlation coefficient. Linear regression analysis was used to establish the relationship between different pressures and the percentage change in intensity. Results:When the ambient pressure was varied under 6 gradients of 20, 25, 30, 35, 40, and 45 cmH 2O, the contrast strength decreased with the pressure increased, and there was a negative correlation between contrast strength and the pressure ( r=-0.971, P<0.001). Under different pressures, the contrast agent intensity showed different degrees of natural decrease in 1 s, 3 s, and 5 s. The difference in the percentage change in contrast agent intensity in each pressure gradient was not statistically significant in 1 s ( P>0.05), whereas the differences in the percentage change in contrast agent intensity in 3 s and 5 s were statistically significant in each pressure gradient (all P<0.05). After microbubble contrast agent was stimulated by ultrasound excitation for 1s, the percentage change in contrast agent intensity was significantly correlated with ambient pressure ( r=-0.976, P<0.001). A linear regression model was fitted with the percentage change in contrast agent intensity after 1 s of stimulation as the independent variable and the pressure as the dependent variable, with the model equation: y=60.075-2.559×x1, where x1 is the percentage change in contrast agent ( R2=0.952, P<0.001). Conclusions:The percentage change in contrast intensity after 1 s of ultrasound excitation of microbubble contrast agent is a favorable predictor of hydrostatic pressure at 6 pressure gradients of 20, 25, 30, 35, 40, and 45 cmH 2O, which may provide a new method for noninvasive monitoring of portal vein pressure for clinicans.

Objective:To establish a nomogram prediction model for recurrence within 2 years after radical resection of hepatocellular carcinoma (HCC) based on clinical and ultrasonographic characteristics.Methods:Clinical data from 405 HCC patients (including 327 males and 78 females), aged 60 (53, 66) years old, who underwent radical hepatectomy in the Zhongshan Hospital, Fudan University, from January to December 2021, were retrospectively collected. The patients were divided into two groups: the training group ( n=283) and the validation group ( n=122). Based on recurrence within 2 years after surgery, the 283 patients in the training group were further categorized into the recurrence group ( n=73) and the non-recurrence group ( n=210). Among the 122 patients in the validation group, 33 had recurrence within 2 years, while 89 did not. Data on age, microvascular invasion, alpha-fetoprotein (AFP), AFP lentil lectin-reactive fraction (AFP-L3), protein induced by vitamin K absence or antagonist-II (PIVKA-II), tumor number, and enhancement homogeneity were collected. Logistic regression analysis was performed on the training group to identify risk factors associated with postoperative recurrence, and a nomogram model for predicting HCC recurrence was constructed based on these factors. Calibration curves were used to compare the consistency between predicted and actual outcomes in both the training and validation groups. Results:Multivariate logistic regression analysis revealed that younger age ( OR=0.976, 95% CI: 0.953-1.000, P=0.004), higher AFP-L3 ( OR=1.066, 95% CI: 1.014-1.120, P=0.012), higher PIVKA-II ( OR=1.000, 95% CI: 1.000-1.001, P=0.042), multiple tumors ( OR=0.399, 95% CI: 0.225-0.706, P=0.038), and heterogeneous enhancement ( OR=0.472, 95% CI: 0.243-0.916, P=0.045) were significant risk factors for recurrence after partial hepatectomy in HCC patients. The nomogram constructed based on these variables had a C-index of 0.87 (95% CI: 0.81-0.93) in the training group and 0.83 (95% CI: 0.77-0.89) in the validation group. The calibration curves for predicting recurrence within 2 years after partial hepatectomy in HCC patients showed a high degree of fit in both the training and validation groups, indicating a good agreement between predicted and actual outcomes. Conclusion:The nomogram model constructed based on preoperative clinical and ultrasonographic characteristics can effectively predict the risk of recurrence within 2 years after radical resection of HCC.

Objective To investigate the value of Baveno Ⅶ criteria versus Expanded Baveno Ⅶ criteria in screening for high-risk varices (HRV) in patients with compensated advanced chronic liver disease (cACLD). Methods A total of 146 patients with cACLD who were admitted to Beijing Shijitan Hospital, Capital Medical University, from January 2016 to December 2018 were enrolled, and according to the absence or presence of HRV based on gastroscopy, they were divided into HRV group with 68 patients and control group with 78 patients. Clinical data, liver stiffness measurement (LSM), and gastroscopy findings were analyzed, and different Baveno Ⅶ criteria were analyzed in terms of their sensitivity and specificity in the diagnosis of HRV. The Mann-Whitney U test and the McNemar test were used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. A univariate logistic regression analysis was performed for the variables used to predict HRV, and a multivariate analysis was performed for the variables with P < 0.1. The two sets of Baveno Ⅶ criteria were compared in terms of their sensitivity and specificity in the diagnosis of HRV. Results A total of 146 patients were enrolled in the study, among whom 68 (46.6%) were found to have HRV. The median age was 54 years (range 29-84 years), male patients accounted for 65.8%, and hepatitis B virus was the main etiology observed in 115 patients (78.8%). The univariate logistic regression analysis showed that LSM and platelet count (PLT) were associated with HRV (both P < 0.05). The multivariate analysis showed that based on Baveno Ⅶ criteria, LSM > 20 kPa or PLT < 150×10 9 /L was associated with HRV (both P < 0.05), and based on Expanded Baveno Ⅶ criteria, LSM > 25 kPa or PLT < 110×10 9 /L was associated with HRV (both P < 0.05). LSM and PLT had an area under the ROC curve of 0.797 (95% confidence interval [ CI ]: 0.723-0.859) and 0.789 (95% CI : 0.714-0.852), respectively, in the diagnosis of HRV. There were significant differences in the prevalence rates of esophageal and gastric varices and HRV between the patients who met Baveno Ⅶ criteria and those who did not meet such criteria ( χ 2 =23.14 and 23.14, both P < 0.001), as well as between the patients who met Expanded Baveno Ⅶ criteria and those who did not meet such criteria ( χ 2 =43.51 and 25.71, both P < 0.001). Although a higher proportion of patients were exempted from gastroscopy based on Expanded Baveno Ⅶ criteria (32.9% vs 13.7%), Baveno Ⅶ criteria had higher sensitivity (0.98 vs 0.88) and negative predictive value (0.95 vs 0.83) and could better avoid the missed diagnosis of HRV (1.0% vs 9.3%). Conclusion Baveno Ⅶ criteria are more suitable for the screening for HRV in cACLD patients in China.

Objective:To explore the clinical efficacy of CT-guided 125I seed implantation in patients with oligometastatic non-small cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) activating mutations (EGFRm+ ) without progression after first-line EGFR-tyrosine kinase inhibitors (TKIs) treatment. Methods:From January 2015 to January 2019, 89 eligible patients (38 males, 51 females; age: (62±11) years) in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. They were divided into 2 groups according to different treatment methods. The 125I seeds were implanted for oligometastatic lesions and/or primary tumors without progression after first-line EGFR-TKIs therapy in local consolidation treatment group (Group A, n=32). The maintenance treatment group (Group B, n=57) only received EGFR-TKIs until disease progression. The progression-free survival (PFS) and overall survival (OS) of the 2 groups were estimated by Kaplan-Meier curves, and were compared by using log-rank test. Complications in Group A were observed. Results:The follow-up time of the group A and group B were 36.5(31.0, 43.3) months and 30.0(24.0, 35.0) months respectively. The median PFS and OS in group A were 15.0(95% CI: 12.8-17.2 ) months and 37.0(95% CI: 33.9-40.1) months, both of which were significantly longer than those in group B (12.0(95% CI: 10.9-13.1) months and 31.0(95% CI: 28.9-33.1) months; χ2 values: 8.80, 7.15, P values: 0.003, 0.007). In Group A, the total incidence of complications in CT-guided 125I seed implantation was 21.9%(7/32), and the common complications and adverse events were pneumothorax and hemoptysis. Only 1 patient underwent chest tube insertion, and the rest were treated with conservative treatment. No operation related death occurred. Conclusion:CT-guided 125I seed implantation is safe and feasible for patients with EGFRm+ oligometastatic NSCLC without progression after first-line EGFR-TKIs treatment, and can prolong the PFS and OS of patients.
