Objective To summarize and analyze the clinical first aid characteristics and etiology classi-fication of adult acute laryngeal obstruction so as to guide the targeted treatment in clinic.Methods The clini-cal data of the patients with the main symptoms such as suffocation and inspiratory dyspnea visiting in this hospital from January 2015 to December 2021 were collected.They conducted emergency tracheotomy for first aid,and their etiological distribution and characteristics were analyzed.Results A total of 94 patients with a-cute laryngeal obstruction and emergency tracheotomy caused by various causes were collected,73 males and 21 females,aged (65.44±12.23)years old.The proportions of disease causes from high to low were in turn 60 cases of tumor (63.83％),12 cases of bilateral vocal cord paralysis (12.77％),11 cases of inflammation (11.70％),5 cases of trauma (5.32％),2 cases of laryngeal edema (2.13％),2 cases of giant foreign matter (2.13％) and 2 cases of tube taking off after tracheotomy (2.13％).The age had the statistical difference a-mong different etiologies (F=4.463,P=0.001).The age in the patients with tumor,infection and bilateral vocal cord paralysis was greater than that of the other groups with statistical difference[(67.21±10.45)years old vs.(52.00±16.42)years old,t=2.993,P=0.012].The male patients with different severities of acute la-ryngeal obstruction were more than female patients,but the difference in the sex composition was not statisti-cally significant (P=0.469).Among the patients with emergency tracheotomy,there were 6 cases of compli-cating incision bleeding and 5 cases of subcutaneous emphysema;1 case of right pneumothorax complicating apposite side atelectasis,and all were improved by symptomatic treatment.Conclusion Acute laryngeal ob-struction in adults is critical.The common causes include tumor,bilateral vocal cord paralysis and inflamma-tion.The risk of emergency tracheotomy and complications occurrence risk are relatively high.

Objective:To explore the feasibility of constructing an objective tinnitus subtype model based on peripheral blood differentially expressed genes (DEGs) using a combination of Weighted Gene Co-expression Network Analysis (WGCNA) and Random Forest algorithm (RF).Methods:From October 2019 to June 2020, peripheral blood DEGs were obtained from 37 patients (from the Third Affiliated Hospital of Sun Yat-sen University)with chronic subjective high-frequency tinnitus (21 unbothersome type, 16 bothersome type) and 20 healthy volunteers through high-throughput sequencing. WGCNA was used to construct gene modules with different expression patterns and analyze their relationships with tinnitus characteristics. Subsequently, RF was employed to build subtype models, which were evaluated by the area under the receiver operating characteristic curve (AUC), accuracy, and F1-score.Results:A total of 12 351 intergroup DEGs were divided into 9 gene modules. Among them, MEblue, MEgreen, and MEbrown showed significant negative correlations with the healthy volunteer group, while MEpink showed a significant positive correlation with the tinnitus distress group. The "Tinnitus vs. Normal" and "Compensatory vs. Decompensatory" subtype models, based on MEblue and MEpink respectively, both had AUCs greater than 0.80, accuracies above 90%, and F1-scores above 0.90, indicating good performance.Conclusions:Peripheral blood DEGs are potential biological indicators for objective classification of subjective tinnitus. The combined application of WGCNA and the Random Forest algorithm should be a viable approach to constructing an objective tinnitus subtype model. However, further exploration and refinement are needed to validate the model′s generalizability, cross-dataset performance, and algorithm optimization.

Objective To analyze the effect of Meleis transition theory in the intervention of family caregivers of advanced lung cancer patients.Methods From January 2022 to June 2023,94 patients with advanced lung cancer and their family caregivers treated in 4 hospitals of a tertiary A hospital in Zhejiang Province were selected by convenience sampling method,and they were divided into a control group(n=47)and an experimental group(n=47)according to random number table method.The family caregivers of the experimental group received a four-week intervention based on the Meleis transition theory on the basis of routine nursing education,including role recognition,disease knowledge,life care,psychological support,and social resource connection.Family caregivers in the control group received routine nursing education,caregiving education and guidance.The differences in the readiness,caring ability,psychological burden and patients'quality of life were compared between the 2 groups.Results There was no lost follow-up cases in the control group and experimental group.After intervention,the preparation,ability,and quality of life of family caregivers in the experimental group were better than those in the control group,and the psychological burden of caregivers was significantly lower than that in the control group(P＜0.05).Conclusion The intervention of caregiving ability of family caregivers based on Meleis transition theory can effectively improve the caregiving ability of caregivers,reduce the psychological burden of caregivers,improve the quality of care,and improve the quality of life of patients.

Objective:This study aimed to evaluate the global research landscape, identify trends, and determine hotspots concerning hepatoma recurrence post-liver transplantation.Methods:We conducted a bibliometric analysis usinga systematic search was conducted in the Web of Science Core Collection database from Jan. 1992 to Oct. 2023 to identify relevant articles on hepatoma recurrence after liver transplantation. Articles were selected based on inclusion and exclusion criteria and analyzed for publication trends by country/region, journal, author, institution, citation, and keyword. Visualization tools such as Citespace, VOSviewer, and Bibliometric.com were utilized for statistical analysis, identification of emerging trends, and clustering of keyword co-occurrence.Results:Out of 4,936 articles retrieved, 1,189 were included in the final analysis. There was a notable increase in publications on hepatoma recurrence following liver transplantation from 1992 to 2021, peaking in 2021 both globally (n=103) and nationally (n=32). China has the largest number of publications in this field (n=308), maintaining significant collaboration with the United States, South Korea, Japan, Canada. 'Liver Transplantation’ journal had the highest number of publications (n=113). Zhejiang University was the leading institution (n=74), with Academician Zheng Shusen being the most prolific scholar (n=76 publications). Citation emergence detection found that Italian scholar Mazzaferro's Predicting survival after liver transplantation in patients with hepatocellular carcinoma beyond the Milan criteria: a retrospective, exploratory analysis published on The Lancet Oncology in 2009 had the highest burst strength (36.98). Five bursting keywords were identified: alpha fetoprotein, model, validation, sorafenib, and risk. Cluster analysis of keyword co-occurrence revealed five primary research themes: the medication for hepatocellular carcinoma recurrence after liver transplantation, recipient selection criteria, prognostic factors, development and validation of recurrence prediction model, and local treatments for hepatocellular carcinoma.Conclusions:The study underscores rapid advancements in the research on hepatocellular carcinoma recurrence post-liver transplantation over the past three decades, with significant contributions from Chinese scholars, particularly from Zhejiang University and Academician Zheng Shusen. The evolving research hotspots have shifted from transplantation experiences and recipient selection criteria to early post-transplant recurrence risk prediction and therapeutic strategy development.

OBJECTIVE: To evaluate the effectiveness of limited internal fixation combined with a hinged external fixator in the treatment of peri-elbow bone infection. METHODS: The clinical data of 19 patients with peri-elbow bone infection treated with limited internal fixation combined with a hinged external fixator between May 2018 and May 2021 were retrospectively analyzed. There were 15 males and 4 females with an average age of 44.6 years (range, 28-61 years). There were 13 cases of distal humerus fractures and 6 cases of proximal ulna fractures. All the 19 cases were infected after internal fixation of fracture, and 2 cases were complicated with radial nerve injury. According to Cierny-Mader anatomical classification, 11 cases were type Ⅱ, 6 cases were type Ⅲ, and 2 cases were type Ⅳ. The duration of bone infection was 1-3 years. After primary debridement, the bone defect was (3.04±0.28) cm, and the antibiotic bone cement was implanted into the defect area, and the external fixator was installed; 3 cases were repaired with latissimus dorsi myocutaneous flap, and 2 cases were repaired with lateral brachial fascial flap. Bone defects repair and reconstruction were performed after 6-8 weeks of infection control. The wound healing was observed, and white blood cell (WBC), erythrocyte sedimentation rate (ESR), and C-reaction protein (CRP) were reexamined regularly after operation to evaluate the infection control. X-ray films of the affected limb were taken regularly after operation to observe the bone healing in the defect area. At last follow-up, the flexion and extension range of motion and the total range of motion of the elbow joint were observed and recorded, and compared with those before operation, and the function of the elbow joint was evaluated by Mayo score. RESULTS: All patients were followed up 12-34 months (mean, 26.2 months). The wounds healed in 5 cases after skin flap repair. Two cases of recurrent infection were effectively controlled by debridement again and replacement of antibiotic bone cement. The infection control rate was 89.47% (17/19) in the first stage. Two patients with radial nerve injury had poor muscle strength of the affected limb, and the muscle strength of the affected limb recovered from grade Ⅲ to about grade Ⅳ after rehabilitation exercise. During the follow-up period, there was no complication such as incision ulceration, exudation, bone nonunion, infection recurrence, or infection in the bone harvesting area. Bone healing time ranged from 16 to 37 weeks, with an average of 24.2 weeks. WBC, ESR, CRP, PCT, and elbow flexion, extension, and total range of motions significantly improved at last follow-up ( P<0.05). According to Mayo elbow scoring system, the results were excellent in 14 cases, good in 3 cases, and fair in 2 cases, and the excellent and good rate was 89.47%. CONCLUSION Limited internal fixation combined with a hinged external fixator in the treatment of the peri-elbow bone infection can effectively control infection and restore the function of the elbow joint.
