Abstract
Description
Technical Field
[0001] The present application relates to the field of intelligent medicine, and specifically relates to a method, device, program product, and computer-readable storage medium for predicting oral mucosal canceration based on pathological images. Background Art
[0002] The oral mucosal canceration process usually goes through three stages: normal oral mucosa, potentially malignant oral lesions, and oral cancer. The growth and metastasis of tumors are closely related to the angiogenesis of tumor microvessels. That is, the formation of microvessels is an important sign of tumor occurrence and development, which can promote genetic changes in normal cells and accelerate the transformation from the potentially malignant lesion stage to the cancer stage. Research shows that there are significant phenomena of neovascularization in oral mucosal diseases such as lichen planus and oral submucous fibrosis, which manifest as potentially malignant disorders. This suggests that the formation, characteristics, and differentiation of microvessels may run through the occurrence and development process of oral mucosal canceration and play a crucial role in regulating this process. Therefore, there is an urgent hope to establish an objective pathological diagnosis standard for predicting the oral mucosal canceration process, aiming to objectively and accurately predict oral mucosal canceration and each stage of the canceration process based on this standard, so as to guide clinical targeted vascular treatment methods to improve the prognosis and survival of patients.

[0045] In a specific embodiment, the results of an animal disease model in which TSCs interfere with the process of oral mucosal carcinogenesis showed that TSCs labeled with EdUApollo 567 entered the vascular system via tail vein injection, circulated through the blood and survived, and resided around the microvessels of tissues and organs at various stages of disease, and at the same time invaded the walls of blood vessels, causing changes in microvascular morphology.
[0046] By comparing the classical microvascular morphological characteristics in the oral mucosa carcinogenesis process between the control group and the experimental group, the statistical results of the microvascular morphology in the carcinogenesis process of the control group showed that in the normal group, the oval microvascular morphology was the main type; in the precancerous lesion tissue group, the fused and budding microvascular morphologies were the main types; in the well-differentiated squamous cell carcinoma group, the fused and budding microvascular morphologies were the main types; in the moderately differentiated squamous cell carcinoma group, the fused, budding, and finger-like advancing microvascular morphologies were the main types; in the poorly differentiated squamous cell carcinoma group, the finger-like advancing microvascular morphology was the main type.

[0047] The LCM targeted and captured the characteristic microvascular structures at each stage of the oral mucosal carcinogenesis process in the control group and the experimental group, and was associated with TMT analysis. A total of 2,215 differentially expressed proteins with different expression levels were identified. Among them, there were 1,025 up-regulated proteins and 1,190 down-regulated proteins in the experimental group of the carcinogenesis process compared with the control group of the carcinogenesis process; there were 5 up-regulated proteins with differential expression and 1 down-regulated protein with differential expression at each stage between the control group and the experimental group of the carcinogenesis process; when comparing each stage of the control group of the carcinogenesis process with each other, there were 4 up-regulated proteins and 17 down-regulated proteins; when comparing each stage of the experimental group of the carcinogenesis process with each other, there were 2 up-regulated proteins and 2 down-regulated proteins. Through statistical analysis, 1 up-regulated protein and 4 down-regulated proteins were screened out by t-test or chi-square test, and differentially expressed proteins (DEPs) with FC>0.8 were selected for subsequent experimental verification, namely angiopoietin-like protein 2 (ANGPTL2), cytokeratin 15 (CK15), and eukaryotic translation elongation factor 1 epsilon 1 (EEF1E1). The results of Western blot and immunohistochemistry showed that: compared with the control group of the carcinogenesis process, the expression level of CK15 showed an upward trend in the experimental group of the carcinogenesis process, while the expression levels of ANGPTL2 and EEF1E1 showed a downward trend. In each stage of oral mucosal carcinogenesis in the control group, the expression level of CK15 gradually increased, the expression level of ANGPTL2 gradually increased from normal to well-differentiated squamous cell carcinoma stage, and gradually decreased from well-differentiated squamous cell carcinoma to poorly-differentiated squamous cell carcinoma stage, with the highest expression level in the well-differentiated squamous cell carcinoma stage. The expression level of EEF1E1 gradually increased from normal to moderately-differentiated squamous cell carcinoma stage, and gradually decreased from moderately-differentiated squamous cell carcinoma to poorly-differentiated squamous cell carcinoma stage, with the highest expression level in the moderately-differentiated squamous cell carcinoma stage. In each stage of oral mucosal carcinogenesis in the experimental group, the expression level of CK15 gradually increased, the expression level of ANGPTL2 gradually increased from normal to precancerous lesion stage, and gradually decreased from precancerous lesion to poorly-differentiated squamous cell carcinoma stage, with the highest expression level in the precancerous lesion stage. The expression level of EEF1E1 gradually increased from normal to well-differentiated squamous cell carcinoma stage, and gradually decreased from well-differentiated squamous cell carcinoma to poorly-differentiated squamous cell carcinoma stage, with the highest expression level in the well-differentiated squamous cell carcinoma stage.
[0048] In a specific embodiment, nude mice were purchased from Beijing Huafukang Bioscience Co., Ltd. They were 4 weeks old, male, with a body weight of about 20 g, and there were 100 in total. They were randomly divided into an experimental group and a control group. Each group was further divided into 5 subgroups, resulting in a total of 10 subgroups with 10 mice in each subgroup. The grouping of the control group and the experimental group was as followsFigure 4 As shown in Figure 4 , primary culture of HGECs: In a sterile laminar flow hood, healthy and non - inflamed human gingival epithelial tissues were washed with normal saline and double antibiotics, and the surface epithelial tissues of the gingiva were separated. The epithelial tissues were cut into small pieces of about 1 mm³ and spread flat on the bottom of the culture flask, with a 5 - mm interval between each small piece of tissue. An appropriate amount of high - glucose culture medium containing 15% fetal bovine serum was added to the bottom of the culture flask. The culture flask was incubated in an incubator at 37°C and 5% CO₂ for 2 h, then gently flipped and placed flat to allow the culture medium to slowly cover the tissue pieces at the bottom of the culture flask for primary culture. The culture medium was changed once every 3 - 5 d. When the cells around the tissue pieces covered about 85% of the bottom of the flask, sub - culture and amplification were carried out at a ratio of 1:2.

After injection, the status of the nude mice and the conditions of the injection sites were closely observed, and the body weights of the nude mice were regularly recorded when lumps appeared at the injection sites. 3. One week after injecting HGECs into egn nude mice, and 1 week, 3 weeks, 5 weeks, and 7 weeks after inoculating HSC4 into egpl, eghdscc, egmdscc, and egpdscc nude mice respectively, the suspension of TSCs labeled with EdU Apollo 567 (the cell count was 1×107 cells / mL) was injected into the tail vein of the nude mice, 0.1 mL per mouse, and a total of 50 mice were injected. 4. One week after receiving the tail vein injection of the TSCs suspension, egn, egpl, eghdscc, egmdscc, and egpdscc nude mice were euthanized (a 5% sodium pentobarbital solution prepared with normal saline, intraperitoneally injected at 0.5 mL / 100 g). Under sterile conditions, the tissues of the right upper limb of the nude mice with oral mucosal carcinogenesis process in the experimental group were dissected, and samples were taken from the heart, liver, spleen, lungs, and kidneys labeled with EdU Apollo 567, and marks were made respectively. Some tissues of the oral mucosal carcinogenesis process and various organ tissues were fixed with 10% neutral formalin and stained with HE and EdU Apollo 567 in vivo tracer staining; some fresh tissues were frozen-embedded and sectioned onto metal slides, and the microvascular structure with heterogeneity-dominated morphology in the tumor tissue was targeted and captured by LCM for TMT detection; some tissues were stored in a -80°C refrigerator for immunofluorescence staining and western blot.
[0053] In a specific embodiment, morphological identification of the microvascular structure of the oral mucosa carcinogenesis process in the control group and the experimental group: HE staining of the oral mucosa carcinogenesis process tissue: (1) Dewaxing of paraffin sections: Dewax with xylene I and xylene II for 12 minutes each, and treat with ethanol gradients (100%, 95%, 85%, 75%) for 2 minutes each; (2) Treat with hematoxylin for 5 minutes and rinse with water for 2 s; (3) Differentiate with hydrochloric acid alcohol for 2 s and rinse with water for 2 s; (3) Rinse with 1% ammonia water for 1 minute and rinse with water for 2 s; (4) Stain with eosin stain for 30 s and rinse with water for 2 s; (5) Dehydrate with ascending gradient ethanol (75%, 85%, 95%) for 2 s each, and dehydrate with absolute ethanol for 10 minutes; (6) Clear with xylene for at least 5 minutes; (7) Mount with neutral gum, observe the staining results under an upright microscope, collect images and analyze them.
[0054] Analysis of the morphological heterogeneity of the microvascular architecture of the oral mucosa carcinogenesis process in the control group and the experimental group: After identifying the HE-stained oral mucosa carcinogenesis process tissue in the control group, samples were included in each group, with a sample size of n≥3 for each group. Observe the morphological characteristics of microvessels in each group of samples under an upright microscope, and determine the microvascular morphology that dominates the morphological heterogeneity of the microvascular architecture during the oral mucosa carcinogenesis process. Statistically analyze the microvascular morphology composition ratio of n≥3 sections for each group of samples, and perform one-way ANOVA on the proportion of microvascular morphology at each stage of the oral mucosa carcinogenesis process in the control group.
[0055] Immunofluorescence chemical staining: Immunofluorescence staining was performed on the tissues at each stage of the oral mucosa carcinogenesis process dissected from the experimental group and the normal group. (1) The specific steps for preparing and dewaxing paraffin sections are the same as in section 2.7 of the second part; (2) Treat with 3% H2O2 for 10 minutes to block endogenous peroxidase, wash with PBS 3 times, 5 minutes each time; (3) Incubate with primary antibodies (rabbit anti-human ANGPTL2, CK15, and EEF1E1 antibodies are diluted with PBS solution in a certain proportion and used), overnight in a 4°C refrigerator, wash with PBS 3 times, 5 minutes each time; (4) Incubate with secondary antibodies (dilute secondary antibody goat anti-rabbit Rhodamine with PBS solution at a ratio of 1:100), incubate at 37°C in the dark for 1 h, wash with PBS 3 times, 5 minutes each time; (5) Dilute DAPI solution to the working concentration (1:1000), incubate at room temperature in the dark for 30 mim, wash with PBS 3 times, 5 minutes each time; (6) Drop 5% glycerol for mounting, collect images and analyze them under an inverted fluorescence microscope.
[0056] In one embodiment, the pathological characteristics of the animal model of oral mucosa carcinogenesis in the control group are as Figure 5 shown, and the experimental group is as Figure 6as shown. The microvascular morphology of different phenotypes in the control group is as Figure 7 shown.
[0057] In a specific embodiment, Western blot was used to analyze the expression of each protein in cgn, cgpl, cghdscc, cgmdscc, cgpdscc, egn, egpl, eghdscc, egmdscc, and egpdscc. The expressions of ANGPTL2, CK15, and EEF1E1 were detected in all 10 groups, as Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 shown. Normalization was performed using the internal reference GADPH, and the expression of each protein in each group was analyzed by the difference in gray values. Compared with the control group, the expression levels of CK15 in the experimental group showed an upward trend, while the expression levels of ANGPTL2 and EEF1E1 showed a downward trend. In each stage of oral mucosal carcinogenesis in the control group, the expression level of CK15 gradually increased. The expression level of ANGPTL2 gradually increased from the normal stage to the well-differentiated squamous cell carcinoma stage, and gradually decreased from the well-differentiated squamous cell carcinoma stage to the poorly-differentiated squamous cell carcinoma stage, with the highest expression level in the well-differentiated squamous cell carcinoma stage. The expression level of EEF1E1 gradually increased from the normal stage to the moderately-differentiated squamous cell carcinoma stage, and gradually decreased from the moderately-differentiated squamous cell carcinoma stage to the poorly-differentiated squamous cell carcinoma stage, with the highest expression level in the moderately-differentiated squamous cell carcinoma stage. In each stage of oral mucosal carcinogenesis in the experimental group, the expression level of CK15 gradually increased. The expression level of ANGPTL2 gradually increased from the normal stage to the precancerous lesion stage, and gradually decreased from the precancerous lesion stage to the poorly-differentiated squamous cell carcinoma stage, with the highest expression level in the precancerous lesion stage. The expression level of EEF1E1 gradually increased from the normal stage to the well-differentiated squamous cell carcinoma stage, and gradually decreased from the well-differentiated squamous cell carcinoma stage to the poorly-differentiated squamous cell carcinoma stage, with the highest expression level in the well-differentiated squamous cell carcinoma stage.
[0058] In a specific embodiment, the morphological heterogeneity of microvessels in the oral mucosa carcinogenesis process presents different characteristic features at each stage. Among them, the elliptical microvessel morphology is the main type in the normal stage, the fused type and budding type microvessel morphologies are the main types in the carcinomatous lesion stage, the fused type and budding type microvessel morphologies are the main types in the well-differentiated squamous cell carcinoma stage, the fused type, budding type and finger-like advancing type microvessel morphologies are the main types in the moderately differentiated squamous cell carcinoma stage, and the finger-like advancing type microvessel morphology is the main type in the poorly differentiated squamous cell carcinoma stage; 2 TSCs interfere with the oral mucosa carcinogenesis process and induce characteristic changes in microvessel morphological heterogeneity, promoting tumor growth. Among them, the elliptical microvessel morphology is the main type in the normal stage, the fused type microvessel morphology is the main type in the precancerous lesion stage, the fused type microvessel morphology is the main type in the well-differentiated squamous cell carcinoma stage, the budding type microvessel morphology is the main type in the moderately differentiated squamous cell carcinoma stage, and the finger-like advancing type microvessel morphology is the main type in the poorly differentiated squamous cell carcinoma stage; 3 In the oral mucosa carcinogenesis process, the expression level of ANGPTL2 gradually increases from the normal stage to the well-differentiated squamous cell carcinoma stage and gradually decreases from the well-differentiated squamous cell carcinoma stage to the poorly differentiated squamous cell carcinoma stage. After TSCs interfere with the oral mucosa carcinogenesis process, the expression level of ANGPTL2 gradually increases from the normal stage to the precancerous lesion stage and gradually decreases from the precancerous lesion stage to the poorly differentiated squamous cell carcinoma stage; 4 In the oral mucosa carcinogenesis process, the expression level of CK15 gradually increases. After TSCs interfere with the oral mucosa carcinogenesis process, the expression level of CK15 still gradually increases; 5 In the oral mucosa carcinogenesis process, the expression level of EEF1E1 gradually increases from the normal stage to the moderately differentiated squamous cell carcinoma stage and gradually decreases from the moderately differentiated squamous cell carcinoma stage to the poorly differentiated squamous cell carcinoma stage. After TSCs interfere with the oral mucosa carcinogenesis process, the expression level of EEF1E1 gradually increases from the normal stage to the well-differentiated squamous cell carcinoma stage and gradually decreases from the well-differentiated squamous cell carcinoma stage to the poorly differentiated squamous cell carcinoma stage; 6 Compared with each stage of the oral mucosa carcinogenesis process, the expression level of CK15 shows an upward trend in each stage of TSCs interfering with oral mucosa carcinogenesis, while the expression levels of ANGPTL2 and EEF1E1 show downward trends; 7 Based on the characteristics of microvessel architectural morphological heterogeneity in the oral mucosa carcinogenesis process, targeting microvessels by combining ANGPTL2, CK15 and EEF1E1 may be the best strategy for anti-angiogenic therapy in the oral mucosa carcinogenesis process.
