By analyzing the current application of multi-modal data in the diagnosis of gastric "inflammation-cancer" transformation, this study explored the feasibility and strategies for constructing a disease-syndrome integrated diagnosis and treatment system. Based on traditional Chinese medicine (TCM) phenomics, we proposed utilizing multi-modal data from literature research, cross-sectional studies, and cohort follow-ups, combined with artificial intelligence technology, to establish a multi-dimensional diagnostic and treatment index system. This approach aims to uncover the complex pathogenesis and transformation patterns of gastric "inflammation-cancer" progression. Additionally, by dynamically collecting TCM four-diagnostic information and modern medical diagnostic information through a long-term follow-up system, we developed three major modules including information extraction, multi-modal phenotypic modeling, and information output, to make it enable real-world clinical data-driven long-term follow-up and treatment of chronic atrophic gastritis. This system can provide technical support for clinical diagnosis, treatment evaluation, and research, while also offering insights and methods for intelligent TCM diagnosis.

Objective Developing a new type of full-face respiratory protective mask for nuclear facility sites to enhance the sound transmission function and improve the facial adaptability. Methods Combined with feedback from on-site practical needs, this study utilized finite element simulation and ergonomic design methods to investigate the voice transmission units of full-face masks and the facial features of workers at key nuclear facilities. Based on the research results, a new full-face respiratory protection mask structure was designed. Results The optimized structure of passive thin film voice transmission unit significantly enhanced voice transmission efficiency, reducing average voice transmission loss by approximately 70% compared to the control group using thin plate units of equivalent thickness. The existing facial feature test panels insufficiently cover and unevenly classify the facial features of workers at key nuclear facilities. In this study, a specialized test panel based on measurement data achieved a total coverage of 98.5% with high distribution uniformity within each class, providing effective guidance for redesigning full-face mask structural parameters. In comparison to foreign products currently utilized in nuclear facilities, the newly designed full-face mask structure exhibited excellent tightness and structural safety and reliability, and can be cleaned, decontaminated, and reused. Conclusion The results of this study provide significant guidance for improving and optimizing full-face respiratory protection mask used at nuclear facilities, as well as promoting domestic production of high-quality full-face respiratory protection masks.

Tuberculous meningitis is a central nervous system infectious disease caused by Mycobacterium tuberculosis. Its clinical manifestations are nonspecific, and effective pathogenic diagnostic methods are lacking, which often lead to delayed diagnosis and treatment, impacting the prognosis of patients. Therefore, early and rapid etiological diagnosis is crucial for the diagnosis and treatment of tuberculous meningitis. This article provides a review of novel detection technologies developed in recent years that can be used for the diagnosis of tuberculous meningitis, covering nucleic acid detection methods, metabolomics, and proteomics, and offering prospects for future development.

Randomized controlled trials (RCTs) have been widely used in clinical efficacy evaluation of traditional Chinese medicine (TCM), but also having limitations such as high cost,time consuming, and difficulty in patient recruitment and enrollment. The introduction of matching adjusted indirect comparison (MAIC) can alleviate the problem caused by the limitation of traditional RCT methodology to some extent. This paper introduced the basic principles of MAIC, and analyzed the similarities and differences, advantages and disadvantages of the two design methods, that is the anchored and the non-anchored. By analyzing two case studies in the evaluation of TCM efficacy, which are acupuncture for paroxysmal migraine and moxibustion for diarrhea-type irritable bowel syndrome, respectively, this paper introduced the methodological characteristics of MAIC in the efficacy evaluation of TCM, explored the strengths and feasibility of MAIC in the evaluation of efficacy evidence in TCM, the evaluation of efficacy of non-pharmacological TCM therapy and the development of new Chinese medicine, and discussed the limitations of existing research, matching factors and sample size. Additionally, the paper offered prospects by combining the simulation treatment comparison method and emulated target trials, with the goal of providing recommendations and references for the clinical efficacy evaluation of TCM.

Breast cancer (BC) ranks first in the incidence rate of female malignant tumor, the notable features of which include high invasive behavior, high malignant degree and poor prognosis. Resveratrol, a plant antioxidant, has been identified as a potential therapeutic agent for the occurrence and progress of BC. This article explores the mechanism of resveratrol intervention in BC by evaluating several in vitro and in vivo studies. It was found that resveratrol can weaken the proliferation and survival ability of BC cells, suppress their growth, metastasis, and invasion, and reverse their resistance to adriamycin by promoting cell apoptosis, regulating autophagy, inhibiting glycolysis and regulating the tumor microenvironment, expressions of matrix metalloproteinases, epithelial-mesenchymal transition and drug-resistant proteins, etc. The limited number of clinical trial studies on resveratrol, mainly focusing on prevention effect of it on breast cancer, may be one of the reasons that affect the comprehensive evaluation of the anti-cancer efficacy of resveratrol.

Objective:To investigate the effect of low-dose ketamine on neuroinflammation and microcirculation in mice with traumatic brain injury (TBI).Methods:Sixty adult male C57BL/6 mice, weighing 22-28 g, were randomly divided into sham-operated group, TBI group, Sham+ketamine group, and TBI+ketamine group ( n=15). A controlled cortical impingement (CCI) method was used to establish TBI models in the later 2 groups. Sham+ketamine group and TBI+ketamine group were intraperitoneally injected with 30 mg/kg ketamine once daily for 3 d at 30 min after TBI; sham-operated group and TBI group were intraperitoneally injected same amount of saline at the same time points. Cerebral cortical blood flow in 6 mice from each group was measured by laser speckle contrast imaging (LSCI) before, immediately after, 30 min after, 1 d after and 3 d after modeling, respectively. Three d after modeling, immunohistochemical staining and immunofluorescent double label staining were used to detect the nuclear translocation of microglia markers, ionized calcin-antibody-1 (Iba-1) and nuclear factor (NF)-κB p65 in damaged cortical brain tissues in 6 mice from each group. The remaining 3 mice in each group were sacrificed and tissue plasma was extracted 3 d after modeling; levels of NF-κB p65, phosphorylated (p)-NF-κB p65, p-IκB and inducible nitric oxide synthase (iNOS) in cortical brain tissues were detected by Western blotting. Expressions of tumor necrosis factor-α (TNF-α), interleukin-1-β (IL-1β) and interleukin-6 (IL-6), iNOS, reactive oxygen species (ROS) and reactive nitrogen species (RNS) in cortical brain tissues were detected by ELISA. Results:LSCI indicated that, 3 d after modeling, relative blood flow in local cerebral microcirculation of TBI+ketamine group was significantly increased compared with that of TBI group ( P<0.05). Immunohistochemical staining indicated that compared with the sham-operated group and Sham+ketamine group, the TBI group and TBI+ketamine group had significantly increased number of Iba-1 positive cells in the cerebral cortex ( P<0.05); compared with the TBI group, the TBI+ketamine group had significantly decreased number of Iba-1 positive cells ( P<0.05). ELISA indicated that compared with the sham-operated group and Sham+ketamine group, the TBI group and TBI+ketamine group had significantly increased expressions of TNF-α, IL-1β, IL-6, iNOS, ROS and RNS in damaged cortical brain tissues ( P<0.05); compared with the TBI group, the TBI+ ketamine group had significantly decreased expressions of TNF-α, IL-1β, IL-6, iNOS, ROS and RNS in damaged cortical brain tissues ( P<0.05). Immunofluorescent double label staining indicated obviously inhibited NF-κB p65 nuclear translocation in TBI+ketamine group when it was compared with TBI group. Western blotting indicated that compared with the sham-operated group and Sham+ketamine group, the TBI+ketamine group had significantly increased iNOS, NF-κB p65, p-NF-κB p65 and P-IκB protein expressions in damaged cortical brain tissues ( P<0.05); compared with the TBI group, the TBI+ketamine group had significantly decreased protein expressions of iNOS, NF-κB p65, p-NF-κB p65 and p-IκB in damaged cortical brain tissues ( P<0.05). Conclusion:Low-dose ketamine reduces neuroinflammation and improves cerebral microcirculatory blood flow after open TBI, whose mechanism may be related to inhibition of microglia NF-κB/iNOS pathway.

AIM:The objective of this study is to examine the expression of profilin 1(PFN1)in mice with di-abetic nephropathy and determine its association with immune cell infiltration.METHODS:This study presents an analy-sis of PFN1 expression and immune cell infiltration in patients with diabetic nephropathy,utilizing transcriptome expres-sion data from kidney tissue microarray.Additionally,the findings were validated in a diabetic nephropathy mouse model.Sixteen C57BL/6 mice were randomly assigned into two groups,namely the normal group and the model group,in an equal manner.The model group underwent the establishment of the diabetic nephropathy model through intraperitoneal injection of streptozotocin.Subsequently,the expression levels of CD11b,F4/80,CC chemokine receptor 4(CCR4),interleukin-1 receptor type I(IL-1R1),B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax)and caspase-3 in kidney tissue were assessed upon successful establishment of the diabetic nephropathy model.Furthermore,the overexpression of PFN1 was observed in a cellular model of diabetic nephropathy,and the protein expression levels of monocyte chemotactic pro-tein-1(MCP-1)and caspase-3 were assessed.RESULTS:The expression of PFN1 was found to be significantly in-creased in the GSE30122 dataset of transcriptome expression in kidney tissues affected by diabetic nephropathy(P<0.01).This increase in PFN1 expression was found to be correlated with the presence of macrophages and T cells.Fur-thermore,the renal tissue of the diabetic nephropathy model group exhibited significant pathological changes.In this mod-el group,the expression levels of PFN1,CD11b,F4/80,CCR4,IL-1R1,Bax,Bcl-2,and caspase-3 were all significant-ly increased(P<0.01).Overexpression of PFN1 could enhance the expression of MCP-1 and caspase-3 proteins.CON-CLUSION:Macrophages and Th17 cells were identified within the renal tissue of mice with diabetic nephropathy,con-comitant with an up-regulation in the expression of PFN1.This up-regulation was observed to facilitate the induction of apoptosis in the context of diabetic nephropathy.
