Lung cancer still ranks first among malignant tumors in the world and China. Although surgery, radiotherapy, chemotherapy, and other treatments can delay patients' lives, thorny problems remain to be solved, such as adverse reactions after intervention, patient resistance to treatment, and the economic burden of treatment. Traditional Chinese medicine (TCM) featuring a holistic view advocates macro interventions throughout the entire disease cycle, which has the advantages of reducing toxicity, improving efficiency, and enhancing patients' quality of life. The theory of ''sensation and response'' was first recorded in the book of I-Ching. This is the natural law of mutual induction, influence, and interaction among all things in nature. According to the theory of ''Qi monism'' and the proposal of regulating Qi movement and removing toxin by Professor Hua Baojin, we re-examine lung cancer from the primitive thinking in TCM and explain the relevance of Qi movement changes to the occurrence, progression, and treatment of lung cancer. The core pathogeneses of lung cancer are the deficiency of healthy Qi and invasion of deficiency pathogen resulting in the formation of cancer and the internal generation of cancer toxin leading to intermediate dysfunction. Six excesses and Yin pathogen invade and gradually accumulate in the lung and spleen, leading to the generation of cancer toxin, which eventually evolve into lung cancer. The treatment can be based on the theories of five elements and visceral manifestation from three aspects. First, on the basis of syndrome differentiation, medicinal materials of different flavors can be used. Specifically, pungent medicinal materials can be used for dredging and sweet medicinal materials can be used for tonifying. Second, medicinal materials with similar morphology or origin to that in the human body can be used for treating the diseases in corresponding sites. Finally, corrigent medicinal materials can be combined for two-way regulation. These measures can be applied in lung cancer treatment to optimize the prevention and treatment strategies and provide new research directions for TCM diagnosis and treatment of tumors.

Combined with elastic network model(ENM),the perturbation response scanning(PRS)has emerged as a robust technique for pinpointing allosteric interactions within proteins.Here,we proposed the PRS analysis of drug-target networks(DTNs),which could provide a promising avenue in network medicine.We demonstrated the utility of the method by introducing a deep learning and network perturbation-based framework,for drug repurposing of multiple sclerosis(MS).First,the MS comorbidity network was constructed by performing a random walk with restart algorithm based on shared genes between MS and other diseases as seed nodes.Then,based on topological analysis and functional annotation,the neurotransmission module was identified as the"therapeutic module"of MS.Further,perturbation scores of drugs on the module were calculated by constructing the DTN and introducing the PRS analysis,giving a list of repurposable drugs for MS.Mechanism of action analysis both at pathway and structural levels screened dihydroergocristine as a candidate drug of MS by targeting a serotonin receptor of se-rotonin 2B receptor(HTR2B).Finally,we established a cuprizone-induced chronic mouse model to evaluate the alteration of HTR2B in mouse brain regions and observed that HTR2B was significantly reduced in the cuprizone-induced mouse cortex.These findings proved that the network perturbation modeling is a promising avenue for drug repurposing of MS.As a useful systematic method,our approach can also be used to discover the new molecular mechanism and provide effective candidate drugs for other complex diseases.

Magnetic resonance angiography(MRA)is a non-invasive imaging technique used to observe blood vessels.Quantitative analysis of MRA images enables visualization of vascular pathways,condition,and blood flow dynamics,which is essential for diagnosing vascular diseases such as vascular lesions,stenosis,and occlusions.Vessel segmentation serves as the fundamental basis for quantitative vascular analysis.However,the complex morphology of vessels,difficulties in labeling,and scarcity of accurate 3D vascular annotations pose significant challenges for MRA-based vessel segmentation.A strategy of selectively occluding vessels during model training is proposed to enhance the algorithm's capacity to capture the topological structure of blood vessels,thereby improving the continuity of vessel segmentation results.Additionally,a Refine network is incorporated to refine the binary segmentation results of the segmentation network,thereby further improving segmentation accuracy.Model training and testing are carried out using 42 cases of 3D MRA data from the public MIDAS dataset.For the test set,the 3D U-Net baseline model with vessel occlusion strategy shows a β0 Error of 1.2742±0.2103 and a β1 Error of 0.3393±0.0818,respectively,which are 0.1136 and 0.0280 lower than the baseline.The model integrating vessel occlusion strategy and Refine network achieves an average Dice score of 0.7105±0.0125,which is 0.0028 higher than the baseline.These results demonstrate that the proposed method effectively improves both vascular connectivity and segmentation accuracy.

This study investigated the association between a proximal promoter polymorphism of IFNGR1 (interferon-γ receptor α chain, IFNGR-α) and breast cancer susceptibility, as well as the prognostic value of its expression variation in breast cancer patients. A case-control study was conducted at the Sixth Medical Center of PLA General Hospital from June 2020 to June 2022. The study included 182 pathologically confirmed breast cancer patients as the breast cancer group, 177 non-tumor patients with benign breast lesions as the benign breast lesions group, and 229 healthy individuals as the normal control group. 2-3 ml EDTA anticoagulant whole blood samples were collected from all participants, and genomic DNA was extracted and stored for further analysis. Basic patient information was retrieved from the hospital′s electronic medical records by patients′ ID number. The proximal promoter sequence of IFNGR1 was obtained from NCBI, and sequencing primers were designed using Primer Premier 6.0. Sanger sequencing was employed to analyze the IFNGR1 promoter sequence in the three groups, and the results were compared with the Eukaryotic Promoter Database (EPD) sequence using Bioedit software. Statistical analysis was performed on single nucleotide polymorphisms (SNPs) in the IFNGR1 promoter. The TCGA database was utilized to assess the relationship between IFNGR1 expression levels and breast cancer patient survival. The findings revealed that the -56 TG genotype of the IFNGR1 promoter was significantly associated with increased breast cancer risk ( Z=2.73, P<0.05). Notably, IFNGR1 expression was lower in breast cancer group compared to normal control group ( P<0.05). Analysis of the TCGA database indicated that patients with high IFNGR1 expression had longer survival times than those with low expression ( HR=0.87, 95% CI:0.77-0.98, P<0.05). In summary, the IFNGR1 -56 TG genotype is associated with an increased risk of breast cancer, and there is a positive correlation between IFNGR1 expression levels and the survival of breast cancer patients.
