OBJECTIVES: To identify risk factors for recurrent plastic bronchitis (PB) among children with Mycoplasma pneumoniae pneumonia (MPP). METHODS: The clinical data of children with MPP complicated by PB who underwent bronchoscopy at Gansu Province Maternity and Child Health Hospital between July 2023 and January 2025 were retrospectively analyzed. Patients were grouped into a single-episode PB group and a recurrent PB group according to the number of PB episodes. Multivariable logistic regression was used to identify risk factors for recurrent PB. Receiver operating characteristic (ROC) curve analysis was used to assess the diagnostic performance of individual and combined predictors. RESULTS: A total of 264 children were included; 188 (71.2%) had a single episode of PB and 76 (28.8%) had recurrent PB. Multivariable logistic regression analysis showed that decreased serum albumin, atelectasis, and fever persisting beyond 72 hours after the initial bronchoscopy were significantly associated with recurrent PB (all P<0.05). The combination of these predictors yielded a sensitivity of 82.9%, specificity of 61.7%, and an area under the ROC curve of 0.777 (95%CI: 0.714-0.839), outperforming any single predictor (P<0.05). CONCLUSIONS In children with MPP complicated by PB, decreased serum albumin, the presence of atelectasis, and fever persisting beyond 72 hours after the initial bronchoscopy are associated with an increased risk of PB recurrence. In such cases, early repeat or multiple bronchoscopic interventions should be considered.

(±)-Penicithrones A-D (1a/1b-4a/4b), four novel pairs of anthrone-cyclopentenone heterodimers characterized by a distinctive bridged 6/6/6-5 tetracyclic core skeleton, together with three previously identified compounds (5-7), were isolated from the crude extract of the mangrove-derived fungus Penicillium sp., guided by heteronuclear single quantum correlation (HSQC)-based small molecule accurate recognition technology (SMART 2.0) and liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based molecular networking. The structural elucidation of new compounds was accomplished through comprehensive spectroscopic analysis, and their absolute configurations were determined using DP4+ ¹³C nuclear magnetic resonance (NMR) calculations and electronic circular dichroism (ECD) calculations. Compounds 1a/1b-4a/4b demonstrated moderate cytotoxicity against three human cancer cell lines HeLa, HCT116 and MCF-7 with half maximal inhibitory concentration (IC₅₀) values ranging from 15.95 ± 1.64 to 28.56 ± 2.59 μmol·L^-1.

OBJECTIVE: Patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection frequently develop central nervous system damage, yet the mechanisms driving this pathology remain unclear. This study investigated the primary pathways and key factors underlying brain tissue damage induced by the SARS-CoV-2 beta variant (lineage B.1.351). METHODS: K18-hACE2 and C57BL/6 mice were intranasally infected with the SARS-CoV-2 beta variant. Viral replication, pathological phenotypes, and brain transcriptomes were analyzed. Gene Ontology (GO) analysis was performed to identify altered pathways. Expression changes of host genes were verified using reverse transcription-quantitative polymerase chain reaction and Western blot. RESULTS: Pathological alterations were observed in the lungs of both mouse strains. However, only K18-hACE2 mice exhibited elevated viral RNA loads and infectious titers in the brain at 3 days post-infection, accompanied by neuropathological injury and weight loss. GO analysis of infected K18-hACE2 brain tissue revealed significant dysregulation of genes associated with innate immunity and antiviral defense responses, including type I interferons, pro-inflammatory cytokines, Toll-like receptor signaling components, and interferon-stimulated genes. Neuroinflammation was evident, alongside activation of apoptotic and pyroptotic pathways. Furthermore, altered neural cell marker expression suggested viral-induced neuroglial activation, resulting in caspase 4 and lipocalin 2 release and disruption of neuronal molecular networks. CONCLUSION These findings elucidate mechanisms of neuropathogenicity associated with the SARS-CoV-2 beta variant and highlight therapeutic targets to mitigate COVID-19-related neurological dysfunction.

Objective: To assess the cost-effectiveness of pembrolizumab in combination with chemotherapy compared to chemotherapy alone, based on the results of the NRG-GY018 trial, in patients with advanced or recurrent endometrial cancer (EC), stratified by mismatch repair-deficient (dMMR) and mismatch repair-proficient (pMMR) subgroups. Methods: A Markov model was used to simulate patients receiving either pembrolizumab plus chemotherapy or chemotherapy alone. Lifetime costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (ICER) were calculated using a willingnessto-pay (WTP) threshold of $150,000/QALY. Univariate and probabilistic sensitivity analyses were conducted to assess the robustness of our findings. Results: The addition of pembrolizumab to chemotherapy led to an incremental gain of 4.05 QALYs at an additional cost of $167,224, resulting in an ICER of $41,305.09/QALY compared to chemotherapy alone in dMMR EC. Additionally, there were 0.93 additional QALYs at an additional cost of $83,661, which resulted in an ICER of $90,284.80/QALY in pMMR EC.Sensitivity analyses indicated that the cost of pembrolizumab, utility of progressed disease, and utility of progression-free survival had the greatest impact on the results. Probabilistic sensitivity analysis showed that pembrolizumab was considered cost-effective at a 100% probability at a WTP threshold of $150,000 per QALY. Conclusion Pembrolizumab, when combined with chemotherapy, was found to be costeffective compared to chemotherapy alone both for patients with advanced or recurrent dMMR and pMMR EC from the perspective of a payer in the United States.

Objective: This study assessed the cost-effectiveness of atezolizumab in combination with chemotherapy for patients with advanced or recurrent endometrial cancer (EC) from the U.S. payer’s perspective. Methods: A cost-effectiveness study was conducted using a Markov model based on ENGOT-en7/MaNGO/AtTEnd clinical trials. The population consisted of patients with EC, stratified by mismatch repair-deficient (dMMR) and mismatch repair-proficient (pMMR) subgroups. The model simulated patients receiving either atezolizumab plus chemotherapy or chemotherapy alone. Cost, quality-adjusted life-years (QALYs), and incremental costeffectiveness ratio (ICER) were calculated using a Willingness-to-Pay (WTP) threshold of $150,000/QALY. Sensitivity analyses were performed. Results: Adding atezolizumab to chemotherapy in dMMR EC resulted in an incremental gain of 3.31 QALYs but at an additional cost of $855,042, leading to an ICER of $258,391.07/QALY compared to chemotherapy alone. In pMMR EC, there was a gain of 0.50 QALYs with an additional cost of $140,502, resulting in an ICER of $279,239.72/QALY. The overall ICER for EC was $216,459.34/QALY. Scenario analysis indicated that administering atezolizumab for a maximum of 2 years improved cost-effectiveness in dMMR EC, with an ICER of $70,695.96/ QALY falling within the predetermined WTP threshold. Conclusion For patients with advanced or recurrent EC, the combination of atezolizumab and chemotherapy may not prove cost-effective. However, administering atezolizumab for a limited period of maximum 2 years could improve cost-effectiveness in dMMR EC.

Objective To analyze the correlation between shear wave elastography(SWE)hardness measurements of calf muscle in diabetic mellitus patients and Michigan neuropathy screening instrument(MNSI)score.Methods A total of 102 patients with diabetes mellitus who were hospitalized in Lianyungang Hospital of Traditional Chinese Medicine from August 2020 to February 2022 were selected as study object.According to MNSI score,diabetes mellitus patients were divided into group A(0 points ≤MNSI score ≤ 1 point,20 cases),group B(1 point＜MNSI score ≤ 2 points,32 cases),group C(2 points＜MNSI score≤ 3 points,26 cases)and group D(3 points＜MNSI score ≤4 points,24 cases).Thirty normal volunteers were selected as control group.The values of Young modulus of calf gastrocnemius,tibialis anterior and peroneus were measured by SWE and compared under different tension states.Spearman correlation test was used to examine the relationship between MNSI score and Young modulus of calf muscle.Results With the increase of MNSI score,the Young modulus of each calf muscle shear wave decreased in all groups,and the differences between groups were statistically significant(P＜0.05).Young modulus of maximum plantar flexion of gastrocnemius,maximum dorsiflexion of gastrocnemius,maximum plantar flexion of tibialis anterior and peroneus foot varus in diabetic patients were negatively correlated with MNSI score(P＜0.05),and the correlation coefficients were-0.74,-0.73,-0.72 and-0.75,respectively.Conclusion With the aggravation of peripheral neuropathy in diabetes mellitus patients and the decrease of shear wave hardness of calf muscle,SWE can comprehensively evaluate diabetic peripheral neuropathy with MNSI score.

The gut microbiota plays a crucial role in the development of colorectal cancer (CRC). The imbalanced gut microbiota causes damage to the body and disrupts bile acids metabolism, increases susceptibility to CRC, and affects the signaling of farnesol X receptor (FXR), thereby promoting CRC progression. Traditional Chinese medicine has unique advantages in the treatment of CRC due to its synergistic regulatory effects of multiple components, targets, and pathways. It can regulate gut microbiota, intervene in bile acids metabolism, and activate its receptor FXR to inhibit the occurrence and development of CRC. Based on this, this article discusses the main role of the gut microbiota-bile acids-FXR axis in the development of CRC, and reviews the anti CRC effects and mechanisms of traditional Chinese medicine intervention on gut microbiota-bile acids-FXR axis, in order to provide new ideas and methods for the prevention and treatment of CRC.
