Objective To propose a dynamic electrical impedance tomography imaging algorithm based on complementary information fusion network(CIFN)to enhance image quality of dynamic electrical impedance imaging.Methods There were three modules for initialization,multi-frame complementary information extraction and information fusion involved in the CIFN.Firstly,multi-frame dynamic conductivity distribution images were obtained by the initialization module;secondly,spatial complementary information was extracted from the images by using the multi-frame complementary information extraction module;finally,the fusion of lesion target distribution information and target re-reconstruction were realized by the information fusion module to aquire high-quality EIT images.With a 16-electrode multilayer cranial simulation model,the CIFN-based imaging method was compared with Tikhonov regularization algorithm,spectral constraint algorithm and U-Net algorithm in terms of imaging results of types of lesions to verify its performance.Results Compared with the Tikhonov regularization algorithm,spectral constraint algorithm and U-Net algorithm,the proposed CIFN-based algorithm exhibited the lowest mean absolute error(MAE)and the highest structural similarity(SSIM)when used to image different lesion targets,which accurately reconstructed the distribution of lesion targets and gained high imaging stability under common noise levels.Conclusion The proposed CIFN-based imaging algorithm obtains high imaging quality on a cranial simulation model and reconstruction results close to the real model distribution,which provides algorithmic support for subsequent clinical studies on electrical impedance imaging.[Chinese Medical Equipment Journal,2025,46(6):1-6]

OBJECTIVE To collect the data regarding postoperative pneumonia(POP)in recent ten years,analyze the epidemiological rules and understand the distribution of major pathogens causing the POP so as to lay solid foundation for fully implementing' Infection Control in Surgery' initiative.METHODS The clinical data were col-lected from the patients who received surgical procedures in Chongqing University Fuling Hospital from 2015 to 2024.The difference in the incidence of POP between the sexes and among the departments and incidence trends a-mong the age groups and the years as well as the distribution of major pathogens were retrospectively analyzed.RESULTS The total incidence of POP was 1.41％in 2015-2024,2.82％in 2015,showing a year by year downward trend from 2021 to 2024(x2=284 906,P＜0.001).The incidence of POP of the male was 2.42％,higher than 0.70％of the female(P＜0.001).The incidence of POP was 0.29％in the 1 day to 19-year-old age group,2.84％in the 60-year-old age group,and the incidence showed an upward trend with the increase of age(x2=451.053,P＜0.001).The incidence of POP varied in the departments(P＜0.001),with the highest(20.24％)in the neurosurgery department,the lower(0.05％and 0.06％)in the gynecology department and oph-thalmology department.Of the isolated pathogens causing POP,Acinetobacter baumannii accounted for 25.48％,Klebsiella pneumoniae 22.82％,Pseudomonas aeruginosa 14.35％.The percentage of the A.baumannii strains was highest in all the years except for the percentage of K.pneumoniae in 2015 and 2018.CONCLUSIONS The in-cidence of hospital-associated POP is relatively low.The population of advanced age and male is at high risk of POP.POP is highly prevalent in neurosurgery department.The gram-negative bacteria are dominant among the pathogens causing the POP.

Piezo1, a mechanosensitive nonselective cation channel characterized by multiple transmembrane domains, plays a critical role intransducing mechanical stimuli at the cellular membrane and participates in various physiological and pathological processes. Recent studies have established a significant association between Piezo1 and the occurrence and development of multiple ophthalmic disorders. Substantial evidence demonstrates that Piezo1 contributes to ocular disease progression by regulating fundamental cellular processes including proliferation, differentiation, apoptosis, and inflammatory responses, with particular relevance to glaucoma, corneal diseases, retinal disorders, and dry eye syndrome. Piezo1 has made rapid progress in ophthalmology, and has been established as an important mechanosensor in the eye, widely involved in intraocular pressure regulation, retinal function maintenance, corneal homeostasis and repair, and ocular development, and its dysfunction is closely related to the pathological mechanisms of many important blinding eye diseases. Consequently, Piezo1 is not only a key molecule for understanding ocular mechanobiology, but also represents a highly promising therapeutic target. Its study offers new perspectives for the development of novel therapeutic strategies against ocular diseases. This review systematically summarizes current research advances regarding Piezo1 channels in ophthalmology, analyzes their mechanistic involvement in disease processes, and evaluates their potential therapeutic value, thereby offering innovative perspectives for the clinical management of ocular diseases.

Traditional Chinese medicine (TCM) is a well-accepted therapy for atopic dermatitis (AD). However, there are currently no evidence-based guidelines integrating TCM and Western medicine for the treatment of AD, limiting the clinical application of such combined approaches. Therefore, the China Association of Chinese Medicine initiated the development of the current guideline, focusing on key issues related to the use of TCM in the treatment of AD. This guideline was developed in accordance with the principles of the guideline formulation manual published by the World Health Organization. A comprehensive review of the literature on the combined use of TCM and Western medicine to treat AD was conducted. The findings were extensively discussed by experts in dermatology and pharmacy with expertise in both TCM and Western medicine. This guideline comprises 23 recommendations across seven major areas, including TCM syndrome differentiation and classification of AD, principles and application scenarios of TCM combined with Western medicine for treating AD, outcome indicators for evaluating clinical efficacy of AD treatment, integration of TCM pattern classification and Western medicine across disease stages, daily management of AD, the use of internal TCM therapies and proprietary Chinese medicines, and TCM external treatments.

This study aimed to investigate the effects of caffeoylquinic acids from Erigeron breviscapus(EBCQA) on cognitive impairment and mitochondrial dysfunction in Alzheimer's disease(AD), and to explore its underlying mechanisms. The impacts of EBCQA on paralysis, β-amyloid(Aβ) oligomerization, and mRNA expression of mitophagy-related genes [PTEN-induced putative kinase 1(PINK1) homolog-encoding gene pink-1, Parkin homolog-encoding gene pdr-1, Bcl-2 interacting coiled-coil protein 1(Beclin 1) homolog-encoding gene bec-1, microtubule-associated protein 1 light chain 3(LC3) homolog-encoding gene lgg-1, autophagic adapter protein 62(p62) homolog-encoding gene sqst-1] were examined in the AD Caenorhabditis elegans CL4176 model, along with mitochondrial functions including adenosine triphosphate(ATP) content, enzyme activities of mitochondrial respiratory chain complexes Ⅰ,Ⅲ, and Ⅳ, and mitochondrial membrane potential. Additionally, the effects of EBCQA on the green fluorescent protein(GFP)/red fluorescent protein from Discosoma sp.(DsRed) ratio, the expression of phosphatidylethanolamine-modified and GFP-labeled LGG-1(PE-GFP::LGG-1)/GFP-labeled LGG-1(GFP::LGG-1), and GFP-labeled SQST-1(GFP::SQST-1) proteins were investigated in transgenic C. elegans strains. The effect of EBCQA on paralysis was further evaluated after RNA interference(RNAi)-mediated suppression of the pink-1 and pdr-1 genes in CL4176 strain. An AD rat model was established through intraperitoneal injection of D-galactose and intragastric administration of aluminum trichloride. The effects of β-nicotinamide mononucleotide(NMN) and EBCQA on learning and memory ability, neuronal morphology, mitophagy occurrence, mitophagy-related protein expression(PINK1, Parkin, Beclin 1, LC3-Ⅱ/LC3-Ⅰ, p62), and mitochondrial functions(ATP content; enzyme activities of mitochondrial respiratory chain complexes Ⅰ, Ⅲ, and Ⅳ; mitochondrial membrane potential) were investigated in this AD rat model. The results showed that EBCQA delayed paralysis onset in the CL4176 strain, reduced Aβ oligomer formation, and upregulated the mRNA expression levels of lgg-1, bec-1, pink-1, and pdr-1, while downregulating sqst-1 mRNA expression. EBCQA also enhanced ATP content, mitochondrial membrane potential, and the activities of mitochondrial respiratory chain complexes Ⅰ, Ⅲ, and Ⅳ. Furthermore, EBCQA improved the PE-GFP::LGG-1/GFP::LGG-1 ratio, reduced GFP::SQST-1 expression, and decreased the GFP/DsRed ratio. Notably, the ability of EBCQA to delay paralysis was significantly reduced following RNAi-mediated suppression of pink-1 and pdr-1 in CL4176 strain. In AD rats, the administration of NMN or EBCQA significantly improved learning and memory, restored neuronal morphology in the hippocampus, increased autophagosome numbers, and upregulated the expression of PINK1, Parkin, Beclin 1, and the LC3-Ⅱ/LC3-Ⅰ ratio, while reducing p62 expression. Additionally, the treatment with NMN or EBCQA both elevated ATP content, mitochondrial respiratory chain complex Ⅰ, Ⅲ, and Ⅳ activities, and mitochondrial membrane potential in the hippocampus. The above findings indicate that EBCQA improves cognitive impairment and mitochondrial dysfunction in AD, possibly through activation of PINK1/Parkin-mediated mitophagy.

OBJECTIVES: To assess the preliminary efficacy and safety of a dose-intensified C5VD regimen (cisplatin, 5-fluorouracil, vincristine, and doxorubicin) in children with locally advanced hepatoblastoma. METHODS: This prospective study enrolled 24 children with newly diagnosed, locally advanced hepatoblastoma who received the dose-intensified C5VD regimen at Shanghai Children's Medical Center, Shanghai Jiao Tong University School of Medicine, and Shanghai Children's Hospital between January 2020 and December 2023. Clinical characteristics, treatment outcomes, and chemotherapy-related toxicities were analyzed. RESULTS: Of the 24 patients, 13 were male and 11 were female, with a median age at diagnosis of 18.7 months (range: 3.5-79.4 months). All patients achieved complete macroscopic resection of hepatic lesions without liver transplantation. Serum alpha-fetoprotein levels decreased significantly after two chemotherapy cycles. During a median follow-up of 38.4 months (range: 15.8-50.7 months), all patients maintained continuous complete remission, with 3-year event-free survival and overall survival rates of 100%. Across 144 chemotherapy cycles, the incidence rates of grade 3-4 neutropenia, thrombocytopenia, and infections were 97%, 77%, and 71%, respectively; no treatment-related deaths occurred. Notably, 5 patients (21%) developed Brock grade ≥3 hearing loss, of whom 1 required a hearing aid. CONCLUSIONS The dose-intensified C5VD regimen demonstrates significant efficacy with an overall favorable safety profile in the treatment of newly diagnosed, locally advanced pediatric hepatoblastoma. Grade 3-4 myelosuppression and infection are the predominant toxicities. However, high‑dose cisplatin-induced ototoxicity remains a concern, highlighting the need for improved otoprotective strategies.

Objective To explore the value of intravoxel incoherent motion diffusion weighted imaging(IVIM)in preopera-tive diagnosis of microvascular invasion(MVI)in hepatocellular carcinoma(HCC).Methods A retrospective analysis was con-ducted on the imaging data of 38 hepatocellular carcinoma patients who underwent surgical resection at Hunan Medical College General Hospital from 2019 to 2022.According to postoperative pathology results,they were divided into MVI positive group and MVI negative group.The apparent diffusion coefficient(ADC)of DWI parameters,the true diffusion coefficient(D),perfu-sion related diffusion coefficient(D),and perfusion score(f)of IVIM parameters were measured before surgery in HCC pa-tients.The risk factors affecting the occurrence of MVI in HCC were analyzed,and the diagnostic efficacy of subject operating characteristic curve(ROC)was evaluated for MVI.Results The ADC and D values of the MVI positive group were lower than those of the negative group,with statistical differences(both P＜0.05).The area under the D-value curve(AUC),specificity,and sensitivity were 0.741,68％,and 94％,respectively.The area,specificity,and sensitivity under the ADC value curve were 0.714,50％,and 88％,respectively,The area under the curve for the combined diagnosis of MVI by two indicators was 0.832,with a sensitivity of 94％and a specificity of 77％.Conclusion The IVIM parameter D value and DWI parameter ADC value can help to predict microvascular infiltra-tion in hepatocellular carcinoma before surgery,and the diagnostic efficacy of D value is superior to ADC value.IVIM imaging can im-prove the accuracy of preoperative prediction of microvascular invasion in hepatocellular carcinoma.

Objective:To explore the development process of family resilience in children with congenital pseudarthrosis of the tibia (CPT) and to understand the long-term challenges and coping strategies that CPT imposes on the families of affected children.Methods:This study combined purposive sampling and theoretical sampling. It selected 15 caregivers of CPT children from Hunan Children's Hospital for semi-structured interviews. Grounded theory was used to analyze the interview results.Results:The development of family resilience in CPT children's families occurred in three stages: pre-formation stage, formation stage, and maintenance stage. In facing negative emotions and family challenges, caregivers first needed to rebuild their inner beliefs. They then adjusted the family organizational model, adopted open and inclusive communication, and actively sought external support to foster the development of family resilience. Ultimately, caregivers were able to self-regulate their emotions, accumulate caregiving experience, and begin to shift their life perspective.Conclusions:The development of family resilience in CPT children's families is a dynamic, multi-stage process with interactions of multiple factors. Healthcare providers should offer professional health guidance according to the different stages of family development. Moreover, the government and schools should increase their attention and support, working together with families and healthcare providers to enhance family resilience for children with CPT.
