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 To investigate the expansion margins of the planning target volume (PTV) and the planning organ at risk volume (PRV) in nasopharyngeal carcinoma patients immobilized with Styrofoam and head-neck-shoulder mask. Methods A convenient sample of 33 nasopharyngeal carcinoma patients who received radiotherapy at Huanggang Central Hospital from January to October 2024 were selected as the research subjects. All patients underwent cone beam CT scans during the first three treatments and weekly thereafter. After registration and calibration, the setup errors in the X (LAT), Y (LNG), and Z (VRT) directions were recorded. Statistical analysis was performed on the setup errors in each direction to determine differences, and the expansion margins for PTV and PRV were calculated using empirical formulas. Results A total of 229 cone beam CT images were collected. Statistical analysis found that the setup errors (systematic error ± random error) of the patients in the X, Y, and Z directions were 1.05 ± 0.72, 1.30 ± 0.80, and 1.29 ± 0.82 mm, respectively. The expansion margins for PTV in the left-right, superior-inferior, and anterior-posterior directions were 1.40, 1.76, and 1.8 mm, respectively. The expansion margins for PRV in these directions were 0.83, 1.02, and 1.05 mm, respectively. Conclusion For patients immobilized using Styrofoam and head-neck-shoulder mask, it is recommended that the expansion margins for PTV and PRV be set at 2 mm and 1 mm, respectively, in the left-right, superior-inferior, and anterior-posterior directions, and the PRV margin for the spinal cord be set at 3 mm in all directions.

Objective:To prepare decellularized extracellular matrix (dECM)-gelatin methacryloyl (GelMA) composite hydrogels and to study their effects on hepatocyte proliferation.Methods:Hepatic dECM was prepared by elution, and GelMA hydrogel and 10%, 30% and 50% dECM-GelMA composite hydrogels were prepared by pepsin solubilization. The morphology of normal liver and dECM liver was observed by eyes and scanning electron microscopy using hematoxylin-eosin, Sirius red and periodate-Schiff staining, respectively. The internal structure of the dECM-GelMA composite hydrogels was observed by scanning electron microscopy, and the pore diameter was measured. Liver HL-7702 cells were co-cultured with GelMA hydrogel and 10%, 30% and 50% dECM-GelMA composite hydrogels, and the cell proliferation viability was determined by cell counting kit-8. The expression of proliferating cell nuclear antigen (PCNA), Wnt family protein 5a (Wnt5a), β-catenin, extracellular-regulated protein kinase 1/2 (ERK1/2) and phosphorylated ERK1/2 (p-ERK1/2) were detected by Western blotting. Comparisons were made using independent sample t-test or one-factor analysis of variance. Results:After decellularization, the hepatocyte morphology showed rounded depressions, and the extracellular matrix structure was intact. The GelMA hydrogel and 10%, 30% and 50% dECM-GelMA composite hydrogels showed inernally porous structures. The pore diameter increased from (3.06±1.35) μm in the GelMA hydrogel to (16.01±4.02) μm in the 50% dECM-GelMA composite hydrogel. On the 3rd, 5th and 7th day, the relative cell proliferation was higher in the 50% dECM-GelMA composite hydrogel group than that in the GelMA hydrogel group (1.89±0.04 vs 1.53±0.01, 9.36±0.04 vs 3.89±0.09, 7.15±0.27 vs 4.89±0.15, all P<0.05). The relative expression levels of PCNA, Wnt5a, β-catenin, and p-ERK1/2/ERK1/2 proteins in the 50% dECM-GelMA composite hydrogel group were higher than those in the GelMA hydrogel group (2.14±0.04 vs 1.00±0.03, 2.36±0.09 vs 1.00±0.08, 1.45±0.03 vs 1.00±0.04, 1.43±0.04 vs 1.00±0.01, all P<0.05). Conclusions:A dECM-GelMA composite hydrogel can be prepared, which may promote hepatocyte proliferation by upregulating the phosphorylation of ERK1/2 and activating Wnt/β-catenin signaling pathway.

ObjectiveTo explore the molecular mechanism of modified Shengjiangsan in alleviating endoplasmic reticulum (ER) stress and reducing urinary protein in the rat model of diabetic nephropathy (DN). MethodSeventy-five SD rats were randomized into normal, model, low-, medium-, and high-dose (4.37, 8.73, 17.46 g·kg-1, respectively) modified Shengjiangsan, and irbesartan (0.014 g·kg-1) groups, with 10 rats in each group. Rats were administrated with corresponding doses of medications or distilled water by gavage, once a day, for 8 consecutive weeks. After the last administration, the levels of glucose (GLU) in the blood, 24-hour urinary protein (24 h-UTP), and superoxide dismutase (SOD), malondialdehyde (MDA), and glutathione peroxidase (GSH-Px) in the renal tissue were measured. Hematoxylin-eosin staining, periodic acid-Schiff staining, and transmission electron microscopy were employed to observe the pathological changes in rat kidneys. Immunohistochemistry was employed to measure the expression levels of nephrin, podocin, glucose-regulated protein 78 (GRP78), C/EBP homologous protein (CHOP), and activating transcription factor 4 (ATF4) in the kidneys of rats. Western blot was employed to measure the protein levels of silent information regulator 1 (Sirt1), phosphorylated (p)-protein kinase RNA-like endoplasmic reticulum kinase (PERK), and p-eukaryotic translation initiation factor 2 alpha (eIF2α) in rat kidneys. ResultCompared with the normal group, the modeling caused pathological damage to the kidneys, elevated the levels of GLU and 24 h-UTP (P<0.05), up-regulated the protein levels of GRP78, CHOP, ATF4, p-PERK, and p-eIF2α (P<0.05), and down-regulated the protein level of Sirt1 (P<0.05) in rat kidneys. Compared with the model group, modified Shengjiangsan and irbesartan lowered the GLU and 24 h-UTP levels (P<0.05), alleviated the pathological damage in the renal tissue, down-regulated the protein levels of GRP78, CHOP, ATF4, p-PERK, and p-eIF2α (P<0.05), and up-regulated the protein level of Sirt1 (P<0.05). ConclusionModified Shengjiangsan up-regulates Sirt1 expression and inhibits phosphorylation of proteins in the PERK/eIF2α pathway to reduce ER stress and oxidative stress in the renal tissue, thus alleviating the pathological damage in the renal tissue and reducing urinary protein in DN rats.
