Cilia,as cellular sensory organelles,actively partici-pate in and regulate cellular processes such as autophagy and metabolic breakdown during their generation and transportation.Autophagy,on the other hand,is a cell self-protection mecha-nism that maintains cellular homeostasis by clearing aggregates and damaged organelles.Combining recent research findings,this review comprehensively elucidates the bidirectional crosstalk between primary cilia and autophagy.Specifically,it highlights the crucial role of cilia-dependent signaling pathways in activa-ting cellular autophagy and how autophagy regulates cilia genera-tion and length by degrading specific ciliary proteins.Moreover,the dysregulation of primary cilia and autophagy is closely asso-ciated with the clinical manifestations and pathogenesis of vari-ous ciliopathy-related diseases such as polycystic kidney disease and tuberous sclerosis.In terms of pharmacotherapy,this review provides a comprehensive and in-depth overview of small mole-cule inhibitors targeting ciliogenesis,including cytoskeletal drugs and Hedgehog signaling pathway inhibitors.Despite the current limitations in clinical use,these drugs lay the groundw-ork for developing highly specific targeted small molecule inhibi-tors of ciliogenesis and for the treatment of ciliopathies and canc-ers.By systematically discussing ciliogenesis,autophagy,disea-ses and drugs,this review offers new insights for further elucida-ting the crosstalk between ciliogenesis and autophagy,exploring their pathological mechanisms in disease development,and de-veloping therapeutic strategies in the future.

Objective:To investigate the magnetic resonance imaging (MRI) features of non-midline atypical medulloblastoma (MB) in children and analyze the causes of misdiagnosis, so as to improve the understanding and diagnosis of MB.Methods:The clinical and imaging data of 12 cases with non-midline atypical MB confirmed by pathology in Hunan Children′s Hospital from September 2018 to August 2023 were retrospectively analyzed. 12 cases underwent MRI plain scan, 11 cases underwent enhanced scan, and 10 cases underwent diffusion weighted imaging (DWI) and magnetic sensitivity weighted imaging (SWI). The location, morphology, peritumoral edema, size, signal characteristics (cystic lesion or hemorrhage), diffusion and enhancement of the tumor were observed, and the causes of misdiagnosis were analyzed.Results:Among the 12 cases, 9 cases were single, 4 cases were located in the cerebellar hemisphere, 2 cases were in the cerebellopontine angle (CPA), 2 cases were in the brain stem and CPA, and 1 case was in the left parietal lobe. There were 3 cases of multiple lesions, 1 case was located in the right pontine arm and cerebellar hemisphere (2 masses), 1 case was multiple lesions in bilateral cerebellar hemisphere, and 1 case was multiple nodular lesions in the cerebellar vermis mass and left cerebellar hemisphere. 6 cases were irregular in shape and 6 cases were quasi-circular. There were 3 cases without cystic change and 9 cases with varying degrees of cystic change (5 with large cystic change and 4 with small cystic change). 3 cases of hemorrhage, no calcification, 10 cases of DWI showed varying degrees of limited diffusion; 11 cases of enhanced scanning showed mild to obvious enhancement; There were 2 cases without peritumoral edema and 10 cases with mild to moderate peritumoral edema. There were 11 cases with supratentorial hydrocephalus and interstitial cerebral edema, and 1 case without hydrocephalus. 5 cases complicated with subtonsillar hernia; 9 cases were misdiagnosed before operation. Among them, 3 cases were misdiagnosed as high-grade glioma, 3 as low-grade glioma (1 of which was diagnosed as hair-cell astrocytoma), 2 as ependymoma, and 1 as atypical teratoma/rhabdomyoma.Conclusions:The MRI manifestations of non-midline atypical MB in children are varied. Combined with the location of the disease, age and focal signal characteristics, non-midline atypical MB can be included in the diagnostic range after the exclusion diagnosis, which can improve the preoperative diagnosis accuracy of this disease.

Central nervous system(CNS)degenerative disorders refer to a spectrum of pathological alterations triggered by struc-tural damage to cerebral neural tissues,clinically manifested as diverse neurological dysfunction syndromes,including multiple sclerosis(MS),neurodegenerative diseases(NDs),and ische-mic stroke.The hallmark pathological features of these disorders involve irreversible neuronal damage and decompensation of functional neural networks,ultimately leading to progressive neurological deficits.Notably,with the accelerating global popu-lation aging,the incidence of these diseases has surged signifi-cantly.According to WHO statistics,they now rank among the top three global causes of disability and mortality.Current re-search has confirmed that the pathogenesis of CNS degenerative disorders exhibits high heterogeneity,encompassing multifaceted pathophysiological processes such as genetic predisposition,oxi-dative stress,protein misfolding,and metabolic dysregulation.This intricate pathogenic network not only complicates clinical differential diagnosis but also poses substantial challenges to the development of precision therapeutic strategies.Importantly,re-cent studies have revealed that mitochondrial homeostasis disrup-tion-induced inflammatory cascades(termed mitochondrial in-flammation)play a pivotal regulatory role in neurodegenerative progression.Key molecular mechanisms include impaired mito-phagy,aberrant mitochondrial DNA(mtDNA)release and NL-RP3 inflammasome activation.This review systematically deci-phers the molecular regulatory network of mitochondrial inflam-mation,with a focus on its biological effects in critical pathologi-cal events such as blood-brain barrier disruption,microglial hy-peractivation and neuronal apoptosis.The overarching aim is to provide a theoretical foundation for developing innovative thera-peutic strategies targeting mitochondrial homeostasis restoration.

Hepatocellular carcinoma(HCC),which is essentially primary liver cancer,is closely related to CD8+T cell immune infiltration and immune suppression.We constructed a CD8+T cells related risk score model to pre-dict the prognosis of HCC patients and provided therapeutic guidance based on the risk score.Using integrated bulk RNA sequencing(RNA-seq)and single-cell RNA sequencing(scRNA-seq)datasets,we identified stable CD8+T cell signatures.Based on these signatures,a 3-gene risk score model,comprised of KLRB1,RGS2,and TN-FRSF1B was constructed.The risk score model was well validated through an independent external validation co-hort.We divided patients into high-risk and low-risk groups according to the risk score and compared the differ-ences in immune microenvironment between these two groups.Compared with low-risk patients,high-risk patients have higher M2-type macrophage content(P<0.0001)and lower CD8+T cells infiltration(P<0.0001).High-risk patients predict worse response to immunotherapy treatment than low-risk patients(P<0.01).Drug sensitivity a-nalysis shows that PI3K-β inhibitor AZD6482 and TGFβRII inhibitor SB505124 may be suitable therapies for high-risk patients,while the IGF-1R inhibitor BMS-754807 or the novel pyrimidine-based anti-tumor metabolic drug Gemcitabine could be potential therapeutic choices for low-risk patients.Moreover,expression of these 3-gene mod-el was verified by immunohistochemistry.In summary,the establishment and validation of a CD8+T cell-derived risk model can more accurately predict the prognosis of HCC patients and guide the construction of personalized treatment plans.

Objective::To systematically study the mechanisms by which Yinzhihuang (YZH), a traditional Chinese medicine, ameliorates intrahepatic cholestasis of pregnancy (ICP), a liver disorder associated with significant maternal and fetal complications.Methods::This experimental study was conducted from January 2024 to August 2024, utilizing data from public databases (Traditional Chinese Medicine Systems Pharmacology, GeneCards, Online Mendelian Inheritance in Man, DisGeNET, Proteome Xchange) alongside in vitro cell culture experiments. Network pharmacology identified active components of YZH and potential therapeutic targets for ICP. Ultra-performance liquid chromatography–mass spectrometry characterized YZH oral liquid, and its effective doses were evaluated in taurocholic acid (TCA)-induced HTR-8/SVneo cells, an in vitro ICP model. ICP-related targets were gathered from multiple databases, and hub genes were selected through bioinformatics and previously identified differentially expressed proteins. Functional annotation and pathway enrichment analyses were conducted, with validation in TCA-induced cells treated with various YZH concentrations (0.1%–5.0%) compared to controls. Molecular docking confirmed predicted interactions.Results::Using network pharmacology, 104 active compounds and 241 potential targets of YZH were identified. Integration of multiple databases yielded 1897 YZH-related therapeutic targets and 3783 ICP-associated genes. Proteomic analysis identified 227 differentially expressed proteins, from which 10 hub genes were selected; among these, APOA2, COL1A1, and ADIPOQ were significantly upregulated in ICP samples. UPLC-ESI-MS/MS detected 2022 compounds, predominantly flavonoids (25.07%, 507/2022) and phenolic acids (14.44%, 292/2022). Molecular docking demonstrated strong binding affinities between several active compounds and the hub genes. In TCA-induced HTR-8/SVneo cells, 0.5% YZH treatment significantly enhanced cell viability and modulated hub gene expression, supporting a potential multi-target mechanism.Conclusion::This study systematically explored the active components and potential targets of YZH in ICP through network pharmacology, proteomics, and in vitro validation. The findings suggest that YZH may act via the PPAR signaling pathway by modulating genes such as PPARA, PPARG, ADIPOQ, and APOA2.
