Objective To evaluate the clinical characteristics of human immunodeficiency virus (HIV) infected patients with peripheral lung masses (PLMs), and to assess the diagnostic utility of contrast-enhanced ultrasound (CEUS) in differentiating benign and malignant PLMs. Methods A retrospective analysis was performed on the clinical data of 69 patients with PLM treated in Shanghai Public Health Clinical Center from January 2020 to December 2023. All patients underwent percutaneous biopsy, and were categorized into benign group (n＝36) and malignant group (n＝33). 25 patients were HIV-positive and 44 patients were HIV-negative. The clinical features and CEUS parameters in patients were compared across these groups. Results Patients with malignant masses were significantly older than those with benign masses (P＜0.05). In the malignant group, HIV-negative patients exhibited significantly larger tumor diameters compared to HIV-positive patients (P＜0.05); in the HIV-positive patients, no significant difference in tumor size was observed between benign and malignant masses. 19 patients underwent CEUS. 10 malignant masses, irrespective of HIV status (10 positive and 9 negative), commonly presented with indistinct margins, delayed enhancement, heterogeneous perfusion, and delayed peak enhancement on CEUS. 9 benign masses showed earlier peak enhancement compared to 10 malignant masses (P＜0.05); no significant differences were observed in the initiation and washout time of enhancement between benign and malignant masses. In HIV-positive patients, 5 benign masses frequently demonstrated discrepancies between CEUS findings and pathological results. Conclusions The clinical and CEUS characteristics were different between benign and malignant PLMs. However, CEUS shows limited accuracy in distinguishing benign and malignant PLMs, underscoring the need for pathological confirmation.

Objective:To translate the Moyamoya Health Behavior Scale for Adolescent Patients into Chinese and to test its reliability and validity.Methods:Based on the Brislin translation model, the scale was forward-translated, back-translated, cross-culturally adapted, and pretested to develop the Chinese version of the Moyamoya Health Behavior Scale for Adolescent Patients. A convenience sampling method was used to recruit 220 adolescent inpatients with moyamoya disease from the Department of Neurosurgery, Zhongnan Hospital of Wuhan University, between January 2023 and December 2024. Reliability and validity analyses were conducted on the scale.Results:A total of 220 questionnaires were distributed, and 206 valid questionnaires were returned, yielding a valid response rate of 93.64%. The Chinese version of the scale comprised 12 items. The item-level content validity index ranged from 0.875 to 1.000, and the scale-level content validity index was 0.917. Exploratory factor analysis extracted three common factors: treatment implementation for moyamoya disease, health-promoting behaviors for moyamoya disease, and health coping behaviors for moyamoya disease, with a cumulative variance contribution of 69.741%. Confirmatory factor analysis showed that the overall model fit was acceptable. The Cronbach's α coefficient for the total scale was 0.872, with subscale Cronbach's α coefficients ranging from 0.810 to 0.871. The test-retest reliability coefficient for the total scale was 0.983, and the split-half reliability coefficient was 0.766.Conclusions:The Chinese version of the Moyamoya Health Behavior Scale for Adolescent Patients demonstrated good reliability and validity and can be used as an assessment tool for health behaviors in this patient population.

Pulmonary siderosis caused by iron and its compound dust is prone to misdiagnosis and underdiagnosis due to its insidious exposure pathways and non-specific imaging manifestations. This study analyzes the occupational histories and clinical data of six patients with occupational pulmonary siderosis diagnosed at Qingdao Central Hospital between January 2017 and December 2023, summarizes its characteristics, and evaluates the value of AI-assisted diagnosis. All six patients were male, with five being welders. The median dust exposure duration was 9.4 years, and the median latency period was 8.4 years. The main symptoms were chest tightness, cough, and shortness of breath. High-kilovolt chest radiographs were negative in four cases and showed thickened bronchovascular markings in two cases. High-resolution computed tomography (HRCT) revealed centrilobular nodules and tree-in-bud opacities in all cases. Pulmonary siderosis caused by iron and its compound dust is characterized by mild symptoms and a favorable prognosis. Comprehensive assessment and HRCT are crucial for early diagnosis. The development of AI models could enhance diagnostic recognition efficiency and promote precision diagnosis in the future.

OBJECTIVE To investigate the therapeutic effect of Sanhan Huashi Formula(SHF)on respiratory syncytial virus(RSV)-infected mouse models and explore its potential antiviral and anti-inflammatory mechanisms using lipidomics.METHODS Fifty-four BALB/c mice were randomly divided into six groups(n=9):blank group,model group,Ribavirin group(50 mg·kg-1·d-1),and SHF high(15.46 g·kg-1·d-1),medium(7.73 g·kg-1·d-1),and low-dose(3.87 g·kg-1·d-1)groups.A pneumonia model was established by in-tranasal RSV infection,followed by three consecutive days of oral gavage administration.Lung tissues were collected for histopathologi-cal evaluation using hematoxylin-eosin(HE)staining and inflammation scoring.Real-time quantitative polymerase chain reaction(RT-qPCR)was performed to measure mRNA levels of viral gene fusion protein(F),glycoprotein(G),and inflammatory factors tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)to assess lung viral load and inflammation,while immunofluorescence staining was performed to observe the expression of RSV-F protein in lung tissues.Serum lipidomics analysis was conducted using ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry(UPLC-Q Exactive Or-bitrap MS)to identify lipid metabolism changes and differential lipids.RESULTS Compared with the blank group,mice in the model group exhibited marked pulmonary inflammatory cell infiltration and tissue injury,with significantly elevated pulmonary histopa-thology scores and lung index.The lung viral load and the mRNA expression levels of the inflammatory factors TNF-α and IL-6 were significantly increased,and immunofluorescence likewise indicated high expression of RSV-F protein in lung tissue.Relative to the model group,treatment with SHF at all tested doses clearly ameliorated lung tissue injury,effectively suppressed viral gene expression and inflammatory cytokine levels,and reduced the fluorescence signal intensity of RSV-F protein in the lungs.Lipidomics analysis re-vealed that compared with the blank group,the model group exhibited marked disturbances in lipid metabolism-characterized by dys-regulation of triacylglycerol(TG),phosphatidylcholine(PC),lysophosphatidylcholine(LPC),sphingomyelin(SM),diacylglycerol(DG),lysophosphatidylethanolamine(LPE),and phosphatidylethanolamine(PE).High-dose SHF treatment reversed these RSV-induced lipid abnormalities.CONCLUSION SHF effectively alleviates RSV-induced pulmonary inflammation and pathological injury,re-duces pulmonary RSV viral load,and may exert these effects by modulating dysregulated lipid metabolism in peripheral blood.

The high pathogenicity and mortality of respiratory viral infections pose a significant clinical burden.Due to the high de-gree of variability of viral proteins,some current targeted drugs are highly susceptible to drug resistance,and there is an urgent need for the development of effective therapeutic strategies.Glycoconjugates are widely distributed in hosts and viruses,and participate in host-virus interactions,viral replication,innate and adaptive immunity,etc.Aberrant glycosylation is involved in the pathogenesis of a vari-ety of diseases,and anti-respiratory viral strategies targeting glycosylation have the advantages of high specificity,low drug resistance,and broad-spectrum.In recent years,traditional Chinese medicines(TCMs)have shown unique potential in intervening in glycosylation-related antiviral fields due to their multi-target regulatory properties.The aim of this paper is to focus on the biological functions of glycosylation modifications,the research progress of virus infection and potential TCM monomers targeting glycosylation,which not only reveals the scientific connotation of TCM regulation of glycosylation,but also provides a natural molecular library for the development of novel antiviral strategies based on glycosylation intervention.In the future,it is necessary to further combine the tech-niques of glycomics and structural biology to elucidate the precise mechanism of spatial and temporal dynamics of TCM monomers in regulating glycosylation,and to promote the modernization of TCM.

Objective:To investigate the overall drug resistance, drug resistance trend and distribution of drug resistance mutation sites in human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients with antiviral therapy failure in Yunnan Province.Methods:The demographic data and genotype drug resistance of HIV/AIDS population with antiviral therapy failure in Yunnan Province from January 2021 to December 2023 were collected and analyzed by cross-sectional investigation. Statistical analyses were performed using chi-square test.Results:Among 15 159 HIV/AIDS patients, 12 215 cases tested positive by amplification. The circulating recombinant form (CRF) 08_BC was the predominant genetic subtype, accounting for 54.97%(6 714/12 215), followed by CRF01_AE (16.14%(1 972/12 215)) and CRF07_BC (14.48% (1 769/12 215)). When the viral load was ≥200 to <1 000 copies/mL, the incidence of drug resistance was 21.48%(99/461). When it was ≥1 000 to <10 000 copies/mL, the incidence was 51.29%(2 867/5 590). When it was ≥10 000 to <100 000 copies/mL, the incidence was 69.39% (3 979/5 734). When it was ≥100 000 copies/mL, the incidence was 81.86%(352/430). A total of 7 297 drug resistant cases were detected, with a drug resistance rate of 59.74% (7 297/12 215), thus the estimated drug resistance incidence rate among the antiviral treated population in Yunnan Province was 2.00% (7 297/364 238). From 2021 to 2023, the annual drug resistance rates among patients were 60.71%(2 554/4 207), 60.28%(1 671/2 772), and 58.67% (3 072/5 236), respectively, with no statistically significant difference ( χ2=4.47, P=0.107). Among the population with antiviral therapy failure, the drug resistance rates of non-nucleoside reverse transcriptase inhibitor (NNRTI), nucleoside reverse transcriptase inhibitor (NRTI), and protease inhibitor (PI) were 93.70%(6 837/7 297), 44.10%(3 218/7 297) and 5.15%(376/7 297), respectively. The mutation sites with the highest frequencies among the three classes of drugs including NRTI, NNRTI and PI were M184V/I (46.13%(2 123/4 602)), K103N/S (37.14%(2 648/7 129)), L33F (15.50%(82/529)) and M46I/L (15.50%(82/529)), respectively. Analysis of the degree of drug resistance showed that among NNRTI drugs, nevirapine (49.01%(5 987/12 215)) and efavirenz (48.00%(5 863/12 215)) had the highest drug resistance rates, followed by emtricitabine (23.59%(2 882/12 215)) and lamivudine (23.58%(2 881/12 215)) among NRTI drugs. Conclusions:Among HIV/AIDS patients with antiviral therapy failure in Yunnan Province from 2021 to 2023, CRF08_BC is the main genetic subtype. The drug resistance rate of patients increases with the increase of HIV-1 viral load. There is no significant change in the drug resistance rate from 2021 to 2023. NNRTI has the highest drug resistance rate, followed by NRTI, and PI has the lowest. The main mutation sites are M184V/I for NRTI, K103N/S for NNRTI, and M46I/L and L33F for PI. The drug resistance rates of nevirapine, efavirenz, emtricitabine and lamivudine are relatively high.
