Objective To analyze the effect of residual cholesterol (RC) on hearing loss in noise-exposed workers. Methods A total of 3 412 workers engaged in noise operation work in an underground railway enterprise were selected as the research subjects using the judgment sampling method. Their occupational health examination data were collected to analyze the relationship between RC and hearing loss. Results The noise intensity of workplace in the underground rail enterprise was 80.0-85.0 (81.4±3.2) dB(A). The detection rate of hearing loss was 20.2% (691/3 412). The rates of abnormal total cholesterol, triacylglycerol, high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol were 35.6%, 25.7%, 9.5% and 42.4%, respectively. The median and the 25th and 75th percentiles [M(P₂₅,P₇₅)] of RC level were 0.24 (0.15, 0.37) mmol/L. The levels of total cholesterol, triacylglycerol and RC of workers in hearing loss group were higher than those in normal hearing group [M(P₂₅,P₇₅): 4.91(4.37, 5.58) vs 4.84(4.30, 5.46) mmol/L, 1.29(0.91, 1.93) vs 1.16(0.82, 1.67) mmol/L, 0.26(0.16, 0.41) vs 0.24(0.14, 0.37) mmol/L, all P<0.05]. The detection rate of hearing loss in abnormal triglyceride group was higher than that in normal triglyceride group (24.8% vs 18.7%, P<0.01), and the detection rate of hearing loss in abnormal HDL-C group was higher than that in normal HDL-C group (25.0% vs 19.8%, P<0.05). The higher the serum RC level, the higher the detection rate of hearing loss (P<0.01). Multivariate logistic regression result showed that individual with older age, longer work time and higher serum RC level had higher risk of hearing abnormality (all P<0.05), and the risk of hearing abnormality was higher in patients with abnormal fasting blood glucose than patients with normal faseing blood glucose (P<0.05) after controlling for confounding factors such as gender, alcohol consumption, body mass index, and elevated blood pressure. However, abnormal triacylglycerol and HDL-C levels were not significantly related to the risk of hearing abnormality (both P>0.05). Conclusion Serum RC levels are an independent risk factor for hearing loss among noise-exposed workers exposed to noise level of 80.0-85.0 dB(A) in the workplace.

Objective To investigate the types of diseases examined by ultrasonography in a certain island clinic,and to summarize the experience of ultrasound medical support in island area.Methods The ultrasound examination results of patients who were admitted to a certain island clinic from January 2017 to August 2022 were reviewed,and the types and characteristics of diseases examined by ultrasound were analyzed.Results A total of 2 043 patients underwent ultrasound examination.There were 76 disease categories and 1 579 diseases.The top five diseases were fatty liver(13.24%),kidney crystals(12.10%),kidney stones(10.70%),gallbladder polyps(6.33%)and ureteral stones with hydronephrosis(6.02%).Ultrasound could predict the pathological types of appendicitis and guide the clinical decision by observing the width of the appendiceal lumen and the layers of the appendiceal wall.Doppler-assessed ureteric jet could be used to determine the renal function of the affected side of ureteral calculi.Conclusion There are wide and varied disease categories in islands.Sonographers should have comprehensive abilities and qualities.This study can provide reference for the follow-up medical support on island area.

Genitourinary tract infections caused by Chlamydia trachomatis ( Ct) are characterized by their insidious onset, mild symptoms, and prolonged disease course, making them challenging to treat effectively. Chronic persistent infections and associated complications impose a significant burden on both patients and society. Numerous studies have shown that relying solely on antibiotics as first-line therapy may not be sufficient to completely eradicate urogenital Ct infections. Additionally, antibiotic use can lead to the development of Ct resistance and disrupt the body′s microbial balance. Therefore, the development of novel Ct inhibitors is crucial. This review summarizes recent advances in research on Ct inhibitors, aiming to provide a valuable reference for both basic research and clinical treatment of urogenital Ct infections.

Hepatocellular carcinoma(HCC),commonly known as primary liver cancer,is a major cause of malignant tumors and cancer-related deaths in China,accounting for approximately 85％of all cancer cases in the country.Several guidelines have been used to diagnose and treat liver cancer.However,these guidelines provide a broad definition for classifying advanced liver cancer,with an emphasis on a singular approach,without considering treatment options for individual patients.Therefore,it is necessary to establish a comprehensive and practical expert consensus,specifically for China,to enhance the diagnosis and treatment of HCC using the Delphi method.The classification criteria were refined for Chinese patients with HCC,and the corresponding optimal treatment regimen recommendations were developed.These recommendations took into account various factors,including tumor characteristics,vascular tumor thrombus grade,distant metastasis,liver function status,portal hypertension,and the hepatitis B virus replication status of patients with primary HCC,along with treatment prognosis.The findings and rec-ommendations provide detailed,scientific,and reasonable individualized diagnosis and treatment strategies for clinicians.

The second edition of the Chinese guideline for the prevention and treatment of anxiety disorders was published in August 2023, 13 years after the first edition. The revision principles for the second edition were maintaining the first edition's framework, and based on that framework, making necessary revisions by incorporating research progress and supplementing the latest research findings from the domestic studies and the overseas literature. Referring to the DSM-5 and ICD-11 classifications of mental disorders and the actual clinical situation in China, the anxiety disorders in the second edition were panic disorder, generalized anxiety disorder, social anxiety disorder, separation anxiety disorder, and anxiety disorder due to another medical condition. The latest epidemiological data on anxiety disorders in China were added. Following the international guidelines, medications not included in the first edition have been added. Chinese traditional medicines, physical therapy, and internet web-based psychotherapy were also supplemented to fit Chinese clinical settings. Based on a literature review, the latest information on the risks of using antidepressants during pregnancy has been added.A whole course of treatment across the acute phase, consolidation phase, and maintenance phase was further addressed as the treatment principle. First-line and second-line recommendations are provided for medication selections.

Objectives:To investigate the current willingness of depressive outpatients and their doctors in China to engage in shared decision-making (SDM), and to analyze the factors influencing this willingness.Methods:A questionnaire survey was conducted among doctors and patients with depression in 12 tertiary psychiatric hospitals and general hospitals by scanning two-dimensional code and filling in the questionnaire on the mobile terminal. The questionnaire covered patient demographics, emotional state scores, initial diagnosis and treatment, treatment expectations and concerns, symptom improvement needs, medication safety requirements, and diagnosis details (completed by the attending physician). Doctors provided basic information, current depression diagnosis and treatment status, and concerns regarding medications. Logistic regression analysis (univariate and multivariate) was used to identify factors influencing patients′ and doctors′ willingness to engage in SDM.Results:A total of 622 valid patient questionnaires and 45 valid physician questionnaires were collected. Both patients and doctors had a strong willingness to make shared decisions (80.39% (500/622) vs. 60.00% (27/45)). Multivariate binary logistic regression analysis showed that residential location (town versus rural areas: OR (95% CI)=1.895 (1.087-3.305)), acceptable monthly medical expenses (≥1 000-<2 000 CNY vs.<300 CNY: OR (95% CI)=0.194 (0.088-0.427);≥2 000 CNY vs.<300 CNY: OR (95% CI)=0.267 (0.094-0.754)), acceptance of online treatment and consultation (accept versus not accept: OR (95% CI)=3.196 (2.024-5.046)), and knowing about psychotherapy (yes versus no: OR (95% CI)=1.711 (1.003-2.921)) were the factors influencing the willingness of shared decision-making in patients (all P<0.05). For the doctors, the time spent on initial consultation was the factor influencing the willingness to engage in SDM ( OR (95% CI)=1.090 (1.004-1.184), P=0.040). Conclusions:Both depression patients and doctors in tertiary outpatient clinics in China show a strong willingness to engage in SDM, providing a solid foundation for clinical application. However, it is necessary to pay attention to the influence of residential location, acceptable monthly medical expenses, acceptance of online treatment and consultation, and knowledge of psychotherapy should be considered for patients, while the time spent on initial consultations should be considered for doctors.

MEK is a canonical effector of mutant KRAS; however, MEK inhibitors fail to yield satisfactory clinical outcomes in KRAS-mutant cancers. Here, we identified mitochondrial oxidative phosphorylation (OXPHOS) induction as a profound metabolic alteration to confer KRAS-mutant non-small cell lung cancer (NSCLC) resistance to the clinical MEK inhibitor trametinib. Metabolic flux analysis demonstrated that pyruvate metabolism and fatty acid oxidation were markedly enhanced and coordinately powered the OXPHOS system in resistant cells after trametinib treatment, satisfying their energy demand and protecting them from apoptosis. As molecular events in this process, the pyruvate dehydrogenase complex (PDHc) and carnitine palmitoyl transferase IA (CPTIA), two rate-limiting enzymes that control the metabolic flux of pyruvate and palmitic acid to mitochondrial respiration were activated through phosphorylation and transcriptional regulation. Importantly, the co-administration of trametinib and IACS-010759, a clinical mitochondrial complex I inhibitor that blocks OXPHOS, significantly impeded tumor growth and prolonged mouse survival. Overall, our findings reveal that MEK inhibitor therapy creates a metabolic vulnerability in the mitochondria and further develop an effective combinatorial strategy to circumvent MEK inhibitors resistance in KRAS-driven NSCLC.
