Hearing impairment is one of the primary disabilities among children.Hearing aids and cochlear implants are currently the main auditory compensation methods.However,there are significant variations in inter-vention outcomes.With the advancement of auditory intervention techniques and the development of rehabilitative education,achieving comprehensive and precise optimization of rehabilitation outcomes has become a crucial goal in treating hearing impairments.Family support plays a vital role in the treatment,management,and overall health of family members with disabilities,making it an important influencing factor in the intervention effectiveness for chil-dren with hearing impairment.Current domestic and international researches have identified numerous family sup-port factors that influence the rehabilitation outcomes of children with hearing impairment.These factors include family socioeconomic status,level of involvement,language input situations,exposure to books,and others,for which various measurement scales have been developed.This paper provides an overview of the research progress re-lated to family support and children with hearing impairment.

Pulmonary fibrosis is caused by repeated damage to the pulmonary alveolar epithelium,leading to abnormal epithelial-mesenchymal transition and myofibroblast production,resulting in the accumulation of extra cellular matrix and remodeling of the interstitium.Analogous to many tumor cells,pulmonary fibrosis in-volves metabolic reprogramming,encompassing alterations in carbohydrate,lipid,and amino acid metabolism.Notably,this reprogramming is marked by enhanced glycolysis,diminished fatty acid oxidation paired with augmented synthesis,and increased degradation of glutamine.Glycolysis efficiently and rapidly fulfills the en-ergy requirements for the proliferation of macrophages and fibroblasts during fibrotic development.Additionally,the reprogramming of amino acid metabolism in activated fibroblasts not only facilitates collagen synthesis but also intensifies myofibroblast activation by generating reactive oxygen species(ROS)during the production of hydroxyproline.

Entinostat plus exemestane in hormone receptor-positive (HR+) advanced breast cancer (ABC) previously showed encouraging outcomes. This multicenter phase 3 trial evaluated the efficacy and safety of entinostat plus exemestane in Chinese patients with HR + ABC that relapsed/progressed after ≥1 endocrine therapy. Patients were randomized (2:1) to oral exemestane 25 mg/day plus entinostat (n = 235) or placebo (n = 119) 5 mg/week in 28-day cycles. The primary endpoint was the independent radiographic committee (IRC)-assessed progression-free survival (PFS). The median age was 52 (range, 28-75) years and 222 (62.7%) patients were postmenopausal. CDK4/6 inhibitors and fulvestrant were previously used in 23 (6.5%) and 92 (26.0%) patients, respectively. The baseline characteristics were comparable between the entinostat and placebo groups. The median PFS was 6.32 (95% CI, 5.30-9.11) and 3.72 (95% CI, 1.91-5.49) months in the entinostat and placebo groups (HR, 0.76; 95% CI, 0.58-0.98; P = 0.046), respectively. Grade ≥3 adverse events (AEs) occurred in 154 (65.5%) patients in the entinostat group versus 23 (19.3%) in the placebo group, and the most common grade ≥3 treatment-related AEs were neutropenia [103 (43.8%)], thrombocytopenia [20 (8.5%)], and leucopenia [15 (6.4%)]. Entinostat plus exemestane significantly improved PFS compared with exemestane, with generally manageable toxicities in HR + ABC (ClinicalTrials.gov #NCT03538171).

Exosomes are nanoscale extracellular vesicles that are secreted by a variety of cells in the body. They carry particular miRNA, protein molecules, transcription factors, and other information molecules, and they play a role in the pathophysiological regulation of a number of diseases in the body. Exosomes can persist steadily in biological tissues and bodily fluids. Exosomes have quickly advanced in ophthalmology in recent years due to the extensive studies of exosomes in a variety of fields, such as diabetic retinopathy, age-related macular degeneration, autoimmune uveitis, corneal disease, glaucoma, and other diseases. The number of people who are blind caused by diabetic retinopathy is rising as living standards rise. However, it is still unclear how diabetic retinopathy works. In recent years, many studies have found that exosomes play an important role in diabetic retinopathy. In this paper, the most recent developments in exosome studies as they relate to the pathogenesis and progression of diabetic retinopathy are reviewed.

Backgrounds::GALLIUM is a global phase III study that demonstrated significant improvements in progression-free survival (PFS) for obinutuzumab plus chemotherapy (G-chemo) vs. rituximab plus chemotherapy (R-chemo) in previously untreated patients with follicular lymphoma (FL). This study aimed to report the results of a subgroup of patients in China. Methods::Patients were randomized to G-chemo or R-chemo. Responders received maintenance therapy for 2 years or until disease progression. The primary endpoint was investigator (INV)-assessed PFS. Secondary endpoints included the overall response rate (ORR) and complete response rate (CRR) at the end of induction chemotherapy, overall survival (OS), and safety.Results::Overall, 58 patients with FL were randomized to the G-chemo ( n = 25) and R-chemo arms ( n = 33). The INV-assessed PFS rate at 3 years was 81.8% in the G-chemo arm, vs. 70.2% in the R-chemo arm (hazard ratio 0.35; 95% confidence interval: 0.09-1.34; P = 0.1120). The INV-assessed CRRs (without positron emission tomography [PET]) in these arms were 24.0% and 21.2%, respectively, whereas the ORRs were 80.0% and 90.9%, respectively. INV-assessed CRR-PET was 52.6% in the G-chemo, vs. 60.9% in the R-chemo. Median OS was not reached in either arm. Grade 3 to 5 adverse events were more frequent in the R-chemo arm (97.0% vs. 88.0%). Conclusions::The results of this subgroup analysis were consistent with those of the global population, and they suggest that G-chemo has a positive benefit-risk profile in patients from China with FL.Trial registration::ClinicalTrials.gov, No. NCT01332968.

Objective:To explore the application effect of quantitative evaluation nursing in Operating Room in patients undergoing radical resection of rectal cancer.Methods:A total of 114 patients who received radical resection of rectal cancer in Xi'an Daxing Hospital from December 2019 to December 2021 were selected by the convenient sampling method. According to the order of admission, they were divided into the observation group and the conventional group, with 57 cases in each group. The observation group received quantitative evaluation nursing in the Operating Room, while the conventional group received routine Operating Room nursing. The differences in physiological indexes and mood state scores were compared between the two groups.Results:The postoperative diastolic blood pressure, systolic blood pressure and heart rate in the observation group were lower than those in the conventional group ( P<0.05). The scores of depression-frustration, tension-anxiety, fatigue-dullness, anger-hostility and confusion-chaos dimensions of postoperative mood state in the observation group were lower than those in the conventional group, and the energy-vitality score was higher than that in the conventional group ( P<0.05) . Conclusions:Quantitative evaluation nursing in the Operating Room can reduce the psychosomatic stress response in patients undergoing radical resection of rectal cancer.

Long non-coding RNAs (LncRNAs) are abnormally expressed in a variety of tumors and participate in the occurrence and development of tumors. However, the expression and function of many LncRNAs in tumors have not been fully clarified. In this paper, 113 normal breast tissues and 1 109breast cancer tissues were analyzed in TCGT database. LncRNA AL133467. 1 was found to be lowly expressed in breast cancer tissues and negatively correlated with poor prognosis of breast cancer patients. The expression of AL133467. 1 in breast cancer cells was significantly lower than that in normal breast epithelial cells. We overexpressed AL133467. 1 in relatively low-expression breast cancer cells SKBR3and BT474, and cell count and plate colony-formation experiments showed that overexpression ofAL133467. 1 could significantly inhibit the proliferation and colony formation of breast cancer cells (P< 0. 01). Cell scratch and Transwell assays showed that the migration and invasion ability of breast cancer cells overexpressing AL133467. 1 was significantly reduced compared with the control group (P<0. 01). MiRDB database showed that AL133467. 1 had binding sites with miR-661. miR-661 could bind the transducer of ErbB2, 2 (ErbB2, 2, TOB2). qRT-PCR showed that miR-661 was highly expressed inbreast cancer cells and positively correlated with poor prognosis of breast cancer patients (P < 0. 001). Luciferase reporter assays showed that AL133467. 1 had specific binding to miR-661 (P < 0. 01). AL133467. 1 overexpression could inhibit the expression of miR-661 in breast cancer cells (P<0. 0001). Transfection of miR-661 mimics eliminated the inhibitory effect of overexpression of AL133467. 1 on breast cancer cells (P < 0. 001). In addition, qRT-PCR and Western blotting results showed that overexpression of AL133467. 1 up-regulated TOB2 mRNA (P < 0. 0001) and protein levels. But whenmiR-661 mimics were transfected, TOB2 mRNA (P < 0. 0001) and protein levels were significantly inhibited. In conclusion, as a competitive endogenous RNA of miR-661. AL133467. 1 promotes the expression of TOB2, thereby inhibiting the proliferation and invasion of breast cancer cells.

Objective: To compare the accuracy of the centerline extracted based on CT 3D reconstruction and conventional CT 3D reconstruction in measuring the length and degree of laryngotracheal stenosis. Methods: A retrospective analysis was performed on 35 patients with laryngotracheal stenosis (including 19 cases without tracheotomy and 16 cases with tracheotomy) treated in the Department of Otorhinolaryngology Head and Neck Surgery of the First Affiliated Hospital of Guangxi Medical University from March 2006 to March 2016, including 20 males and 15 females, whose ages ranged from 1 to 73 years, with a median age of 40.5 years. And CT data of 20 normal subjects were included in the same period, including 10 males and 10 females, whose ages ranged from 20 to 63 years, with a median age of 37.0 years. The continuous cross-sectional area of the airway perpendicular to the centerline was obtained by Mimics software. The area was compared with the discontinuous cross-sectional areas reconstructed by conventional CT 3D reconstruction software advantage workstation, also the length of cervical trachea, the length of stenosis, and the minimum airway area were compared. Multi-factor linear stepwise regression method was used to analyze the factors influencing the measuring difference between the two methods. Three patients with laryngotracheal stenosis were selected, and the measured stenosis length was compared with the surgical specimens to evaluate the accuracy of the two methods. SPSS 26.0 software was used for statistical analysis. Results: In normal people, the areas of thyroid cartilage notch, glottis, inferio thyroid cartilage margin, inferio cricoid cartilage margin, and suprasternal notch planes measured by Mimics centerline method were smaller than those measured by conventional CT 3D reconstruction (t _{thyroid cartilage notch}=4.685, t_glottis=3.791, t_{lower thyroid cartilage margin}=5.621, t_{lower cricoid cartilage margin}=6.312, t_{suprasternal notch plane}=6.436, P<0.05). And the airway length measured by Mimics centerline method from the inferior thyroid cartilage to the superior sternal notch was longer (t=9.79, P<0.001). In laryngotracheal stenosis, in the non-tracheotomy group, the minimum airway area measured by Mimics centerline method was smaller and the stenosis length was longer than those measured by the conventional CT 3D reconstruction, and the difference was statistically significant (t_{minimum airway area}=2.562, t_{stenosis length}=5.240, P<0.05). In the tracheotomy group, the stenosis length measured by Mimics centerline method was longer than that measured by conventional CT 3D reconstruction, and the difference was statistically significant (t_{stenosis length}=2.854, P<0.05). Multi-factor linear regression analysis showed that different CT thickness had a statistically significant effect on the difference in the length of stenosis measured by the two methods (b=-5.370, t=-3.306, P=0.004), and different tracheal forward angle had a statistically significant effect on the difference in the minimum airway area measured by the two methods (b=-0.419, t=-2.208, P=0.04). The difference between the measured length of the Mimics centerline method and the intraoperative specimens was less than 0.5 mm. Conclusion: The centerline extracted based on CT 3D reconstruction can precisely reflect the laryngotracheal morphology and measure laryngotracheal stenosis more accurately.

Objective:To explore the risk factors of intensive care unit-acquired weakness (ICU-AW) and the characteristics of Medical Research Council (MRC) score and electromyogram.Methods:A case control study was conducted. Patients with mechanical ventilation ≥ 7 days and MRC score admitted to department of respiratory and critical care medicine of China-Japan Friendship Hospital from September 2018 to January 2020 were enrolled, and they were divided into ICU-AW group (MRC score < 48) and non-ICU-AW group (MRC score ≥ 48) according to MRC score. The general situation, past medical history, related risk factors, MRC score, respiratory support mode, laboratory examination results, electromyogram examination results, ICU-AW related treatment, outcome and length of ICU stay were collected, and the differences between the two groups were compared. The risk factors of ICU-AW were analyzed by binary multivariate Logistic regression, and the characteristics of MRC score and electromyogram were analyzed.Results:A total of 60 patients were enrolled in the analysis, including 17 patients in ICU-AW group and 43 patients in non-ICU-AW group. Univariate analysis showed that there were significant differences in acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, sequential organ failure assessment (SOFA) score, brain natriuretic peptide (BNP), blood urea nitrogen (BUN) on the first day of ICU admission and the ratio of invasive mechanical ventilation between ICU-AW group and non-ICU-AW group [APACHEⅡ score: 21 (18, 25) vs. 18 (15, 22), SOFA score: 7 (5, 12) vs. 5 (3, 8), BNP (ng/L): 364.3 (210.1, 551.2) vs. 160.1 (66.8, 357.8), BUN (mmol/L): 9.9 (6.2, 17.0) vs. 6.0 (4.8, 9.8), invasive mechanical ventilation ratio: 88.2% vs. 46.5%, all P < 0.05]. Binary multivariate Logistic regression analysis showed no independent risk factor for ICU-AW. The average MRC score of 17 ICU-AW patients was 33±11. The limb weakness was symmetrical, and the proximal limb weakness was the main manifestation. Electromyography examination showed that the results of nerve conduction examination in ICU-AW patients mainly revealed that the amplitude of compound muscle action potential (CMAP) and sensory nerve action potentials (SNAP) were decreased, and the conduction velocity was slowed down; needle electromyography showed increased area of motor unit potential (MUP), prolonged time limit and a large number of spontaneous potentials. Prognosis evaluation showed that compared with non-ICU-AW group, patients in ICU-AW group underwent more tracheotomy (70.6% vs. 11.6%), longer length of ICU stay (days: 57±52 vs. 16±8), and more rehabilitation treatment (58.8% vs. 14.0%), and the differences were statistically significant (all P < 0.01). Conclusions:The occurrence of ICU-AW may be related to high APACHEⅡ score and SOFA score, high levels of BNP and BUN on the first day of ICU admission and the proportion of invasive mechanical ventilation, but the above factors are not independent risk factors for ICU-AW. The MRC score of ICU-AW patients was characterized by symmetrical limb weakness, mainly proximal limb weakness; in electromyography examination, the nerve conduction examination results mainly showed that CMAP and SNAP amplitude were decreased, and conduction velocity was slowed down; needle electromyography examination showed increased MUP area, prolonged duration and a large number of spontaneous potentials.
