Objective To explore the diagnostic value of deep learning image reconstruction(DLIR)com-bined with low-dose chest computed tomography(CT)with axial scan in the diagnosis of mycoplasma pneumoniae pneumonia(MPP)in children,and to provide reference for clinical practice.Methods 160 cases MPP children from February 2024 to June 2025 were selected as study subjects,and low-dose chest CT with axial scan was performed on all patients.DLIR and conventional adaptive iterative reconstruction-V(ASIR-V)were used for image reconstruction.The objective image quality[background noise(SD),signal-to-noise ratio(SNR),and contrast-to-noise ratio(CNR)],subjective image quality,and CT sign detection rate were compared,and the consistency of DLIR and ASIR-V in the diagnosis of MPP severity and clinical diagnosis was compared.Results As the intensity of DLIR and the weight of ASIR increasd,SD gradually decreased,while SNR and CNR gradually increased.The high-strength DLIR(DLIR-H)SD was lower than that of ASIR with a blending level of 80%(ASIR-V80%).The SNR and CNR were higher than those of ASIR-V80%,showing statistical significance(P<0.05).Ridit test showed that DLIR-H had the best subjective image quality score under different DLIR intensities,and ASIR-V80%had the best subjective image quality score under different ASIR weights.Furthermore,the subjective image quality score of DLIR-H was higher that of ASIR-V80%,and the differences were statistically significant(P<0.05).Using DLIR-H,the detection rates of air bronchogram,pulmonary consolidation,and interstitial infiltration(69.38%,86.88%,20.63%,respectively)were higher than those using ASIR-V80%(50.00%,71.88%,7.50%,respectively),and the differences were statistically significant(P<0.05).Consistency analysis showed that the Kappa value between the diagnostic results of MPP severity using DLIR-H and clinical diagnosis was 0.856(95%CI:0.771～0.996),while that between the diagnostic results of MPP severity using ASIR-V80%and clinical diagnosis was 0.498(95%CI:0.346～0.650).ROC analysis showed that the area under the curve(AUC)for diagnosing MPP severity was 0.925(95%CI:0.872～0.960)for DLIR-H and 0.729(95%CI:0.653～0.796)for ASIR-V80%,and the diagnostic value of DLIR-H was superior to that of ASIR-V80%(Z=3.952,P<0.001).Conclusion DLIR can effectively improve image quality.DLIR-H combined with low-dose chest CT with axial scan has high diagnostic value for the severity of MPP,and can serve as a feasible solution for clinical diagnosis of MPP severity and reducing radiation dose.

Chronic hepatitis B（CHB）is one of the major challenges in the global public health field. As of 2022，approximately 254 million people worldwide were infected with the hepatitis B virus（HBV）. CHB is one of the main causes of liver cirrhosis and hepatocellular carcinoma（HCC）. Nucleos（t）ide analogs（NAs）and interferon therapy can delay the progression of liver fibrosis by inhibiting viral replication，but they cannot completely avoid the problem of heterogeneous treatment responses. Some patients are in a state of low-level viremia（LLV）during treatment. The persistent LLV state can induce chronic inflammation and the progression of liver fibrosis，ultimately increase the risk of HCC. In patients with poor treatment responses，the continuous active viral replication can induce immune disorders，accelerate the evolution of fibrosis to the decompensated stage of liver cirrhosis，and increase the risk of patient death. This article aims to review the definition，mechanisms，and impact on treatment outcomes of LLV and suboptimal response based on the latest research，provide a basis for optimizing antiviral therapy for CHB.
