OBJECTIVE To investigate the molecular epidemiological characteristics of clinical Haemophilus influ-enzae(Hin)isolates from adults and children with community-acquired pneumonia(CAP)so as to provide theo-retical bases for effective prevention and treatment of Hin infection.METHODS The patients who were hospital-ized in respiratory and critical care medicine department and pediatrics department of Xinjiang Production and Con-struction Corps Hospital due to CAP from Jan.2023 to Dec.2024 were enrolled in the study,and the positive rates of Hin in sputum specimens were statistically analyzed.The clinical distribution and results of drug suscepti-bility testing for Hin strains were observed and compared between the adults with CAP and the children with CAP.The capsular types,drug resistance genes and multilocus sequencing typing(MLST)subtypes were detected for 72 strains of Hin.RESULTS The positive rate of Hin was higher among the children with CAP(9.46%)than among the adults with CAP(2.71%).The Hin was more prevalent among the children with CAP than among the adults,it was highly prevalent in autumn and winter,with the population dominated by the children aged between 13 and 17 years old(12.67%).The positive rate of β-lactamase-producing Hin strains was 74.71%among the a-dult patients and 90.17%among the children,respectively;the drug resistance rates to ampicillin were highest(73.86%and 92.57%),the drug resistance rates of the strains isolated from the children to the two types of β-lac-tams were higher than those of the strains isolated from the adults(P<0.05).The non-typeable Hin strains(94.45%)were the predominant type among the 72 strains of Hin,the production of β-lactamase mediated by blaTEM-1 was the major drug resistance mechanism.The result of MLST showed that CC155(ST-155),CC11(ST-103)and CC107(ST-1002)were the main subtypes.CONCLUSIONS The β-lactamase-producing non-typeable Hin strains are dominant among the Hin strains isolated from the adults and children with CAP in this area.The isolation rate of the strains is high among the children than among the adults.The strains are highly prevalent in autumn and winter,and ST-155 is the predominant clone type.The strains are highly resistant to ampicillin,which should be attached great importance to.

Objective To compare the filtration effects of different models of leukocyte filters on erythrocyte suspensions,so as to provide a reference for the selection of leukocyte filters in clinic.Methods The erythrocyte suspensions prepared by Department of Blood Transfusion of The First Affiliated Hospital of Naval Medical University were used for filtration.The test was categorized into three groups based on the model of leukocyte filters,namely,AKTT-type(group Ⅰ),STTB-type(group Ⅱ),and STTA-type(groupⅢ).Each group was randomly assigned 8 bags of erythrocyte suspensions(specification 2U)with hematocrit≤55%and 10 bags of erythrocyte suspensions(specification 2U)with hematocrit>55%,and leukapheresis was applied.The quality indexes of the blood were detected before and after filtration,and the experimental data were comprehensively analyzed to evaluate the leukocyte filtration effect of various filters.Results When the hematocrit of the filtered erythrocyte suspensions was≤55%,there were significant differences in the platelet count after filtration(F=49.94,P<0.001)and filtration time(F=73.45,P<0.001)between groups,and the two indexes in group Ⅰ were superior to those in groups Ⅱ and Ⅲ.When the hematocrit of the filtered erythrocyte suspensions was>55%,there were significant differences in the platelet count after filtration(F=160.69,P<0.000 1),filtration time(F=366.09,P<0.000 1),residual leukocytes(F=4.28,P<0.05),and hemolytic rate(F=8.16,P<0.01)between groups.The platelet count after filtration and filtration time in group I were superior to those in group II and III.The indexes of residual leukocyte and hemolytic rate in groups I and II were superior to those in group III.Conclusion In order to ensure the safety and effectiveness of erythrocyte suspension transfusion,AKTT-type filter can be chosen to perform leukocyte filtration,which can further lower the blood transfusion complications.

Triple-negative breast cancer (TNBC) remains a refractory subtype of breast cancer due to its resistance to various therapeutic strategies. In this study, we introduce a "brake-release and accelerator-pressing" approach to engineer a microneedle patch embedded with copper-doped Prussian blue nanoparticles (Cu-PB) and the ferroptosis inducer sorafenib (SRF) for raised chemodynamic (CDT)/photothermal (PTT) combination therapy against TNBC. Upon transdermal insertion, the dissolving microneedles swiftly disintegrate and facilitate the release of SRF. Under gentle external light exposure, copper ions (Cu2+) and iron ions (Fe3+) were liberated from Cu-PB. The direct chelation of Cu2+ and the indirect suppression by SRF, collectively attenuate glutathione peroxidase 4 (GPX4) enzymatic function, destabilizing the cellular redox equilibrium (referred to as the "brake-release" strategy). The release of Cu2+ and Fe3+ ions instigates a Fenton/Fenton-like reaction within tumor cells, further yielding hydroxyl radicals and elevating reactive oxygen species (ROS) concentrations (referred to as the "accelerator-pressing" strategy). This overwhelming ROS accumulation, coupled with the impaired clearance of resultant lipid peroxides (LPO), ultimately triggers a robust ferroptosis cell death response. In summary, this study presents an innovative combinatorial therapeutic strategy based on dual-ferroptosis induction for TNBC, implying a promising therapeutic platform for developing ferroptosis-centered treatments for this aggressive breast cancer subtype.

Hearing loss is the most prevalent disabling disease. Cochlear implantation(CI) serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system(Favorable, Marginal, Poor). The consensus focuses on common hereditary non-syndromic hearing loss(such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1) and syndromic hereditary hearing loss(such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome), which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

This article focuses on a case study of sitosterolemia in a child who initially presented with hemolytic anemia and thrombocytopenia. Sitosterolemia is a rare autosomal recessive lipid metabolism disorder, difficult to diagnose due to its non-typical clinical manifestations. The 8-year-old patient was initially misdiagnosed with pyruvate kinase deficiency. Comprehensive biochemical and molecular biology analyses, including gene sequencing, eventually led to the correct diagnosis of sitosterolemia. This case highlights the complexity and diagnostic challenges of sitosterolemia, emphasizing the need for increased awareness and accurate diagnosis in patients presenting with similar symptoms.
