ObjectiveTo observe the effect of Liuwei Dihuangwan on behavioral impairments in the rat model of autism spectrum disorder (ASD) and explore the mechanism of action. MethodsTwelve SD pregnant rats were intraperitoneally injected with valproic acid (VPA) (10 rats) or normal saline (2 rats), and male offspring were selected to establish the model of ASD and the control rats. Rats were randomly assigned into model, low-dose (0.75 g·kg-1) and high-dose (1.5 g·kg-1) Liuwei Dihuangwan, vitamin D (positive drug, 3.7×10-5 g·kg-1), and blank groups. Each group was administrated with the corresponding concentration of drugs or the same volume of normal saline by gavage for 2 weeks. After the intervention, the three-chamber social test was conducted to evaluate social interaction and social preference. The open field test was carried out to observe spontaneous behavior and anxiety state. Hematoxylin-eosin staining (HE) was used to observe the pathological changes of the prefrontal tissue. Transmission electron microscopy was employed to observe the ultrastructure of mitochondria in prefrontal neurons. Immunofluorescence was used to detect the expression of ionized calcium-binding adapter molecule-1 (Iba-1) in the prefrontal tissue. Enzyme-linked immunosorbent assay (ELISA) was adopted to measure the levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). Western blot was employed to assess the expression differences of phosphorylated adenosine monophosphate-activated protein kinase (p-AMPK), adenosine monophosphate-activated protein kinase (AMPK), phosphorylated Unc-51-like autophagy-activating kinase 1 (p-ULK1), Unc-51-like autophagy-activating kinase 1 (ULK1), and FUN14 domain-containing protein 1 (FUNDC1). ResultsCompared with the blank group, the model group spent less time sniffing stranger 1 and stranger 2 in the three-chamber social test (P<0.01) and showed reductions in the total distance traveled, average speed, distance traveled in the central area, and time spent in the central area in the open field test (P<0.01). In addition, the model group showed extensive apoptosis of neurons, with shrunken nuclei and red-stained cytoplasm, and extensive necrosis of neurons in the prefrontal tissue, mitochondrial swelling, decreased matrix density, disrupted cristae, and autophagic lysosomes in neurons, increases in the rate of Iba-1 positive cells in the prefrontal area (P<0.01) and the levels of TNF-α and IL-6 (P<0.01), and down-regulation in the expression of p-AMPK/AMPK, p-ULK1/ULK1, and FUNDC1 (P<0.01). Compared with the model group, low-dose and high-dose Liuwei Dihuangwan and the vitamin D prolonged the time spent sniffing stranger 1 and stranger 2 in the three-chamber social test (P<0.05, P<0.01), increased the total distance traveled, average speed, distance traveled in the central area, and time spent in the central area in the open field test (P<0.05, P<0.01), restored the morphology of neurons in the prefrontal tissue, decreased the number of apoptotic cells, alleviated the swelling of mitochondria in neurons, increased the matrix density, mitigated the fragmentation and disorder of cristae, and increased the number of autophagosomes. Moreover, the drugs decreased the rate of Iba-1 positive cells in the prefrontal area (P<0.01), lowered the levels of TNF-α and IL-6 (P<0.01), and up-regulated the expression of p-AMPK/AMPK, p-ULK1/ULK1, and FUNDC1 (P<0.01). ConclusionLiuwei Dihuangwan ameliorate autism-like behaviors and reduce neuronal apoptosis and neuroinflammatory damage in the rat model of ASD by promoting mitophagy mediated by the AMPK/ULK1/FUNDC1 pathway.

ObjectiveTo investigate the effects of Huangqi Jianzhongtang (HQJZ) on macrophage polarization and fat consumption in cancer cachexia (CC) mice. MethodsUltra-performance liquid chromatography-quadrupole/electrostatic field Orbitrap high-resolution mass spectrometry (UPLC-Q-Orbitrap HRMS) was used to control the quality of HQJZ. (1) In vitro experiment: HQJZ-containing serum was prepared, and the optimal concentration was determined by cytotoxicity assay. Mouse monocyte-derived macrophages (RAW264.7) were cultured and randomly divided into six groups, including a blank group, a classically activated macrophages (M1) group, an alternatively activated macrophages (M2) group, a HQJZ + blank group, a HQJZ+M1 group, and a HQJZ + M2 group. The relative expression of macrophage marker genes CD86, inducible nitric oxide synthase (iNOS), CD206, and arginase-1 (Arg1) was detected by real-time quantitative polymerase chain reaction (Real-time PCR ). (2) In vivo experiment: Thirty-two BALB/c mice were randomly divided into a control group, a model group, a medroxyprogesterone acetate (MPA) group, and a HQJZ group. Except for the control group, the other mice were injected with CT-26 colon cancer cells to establish a CC model. Mice in the MPA and HQJZ groups were given MPA (0.13 g·kg-1·d-1) or HQJZ (13.13 g·kg-1·d-1) by gavage, respectively, while mice in the control and model groups were given an equal volume of saline by gavage, with interventions continued for 10 d. Real-time PCR was used to detect the expression of macrophage markers (iNOS, Arg1, CD86, CD206) and fat browning-related genes uncoupling protein 1 (UCP1) and peroxisome proliferator-activated receptor γ (PPARγ) in epididymal adipose tissue. Western blot (WB) was used to detect protein expression levels of UCP1 and PPARγ. Micro-computed tomography (micro-CT) was used to measure residual fat volume, and hematoxylin-eosin (HE) staining was used to assess fat browning and calculate pathological scores. ResultsIn vitro, the dominant effective concentration of HQJZ-containing serum was 12.5%. Real-time PCR results showed that, compared with the blank group, Arg1 expression decreased in the HQJZ+blank group (P<0.05), CD206 showed a downward trend without statistical significance, while iNOS and CD86 expression were significantly increased (P<0.05). Compared with the M1 group, Arg1 and CD206 expression decreased in the HQJZ+M1 group (P<0.05). Compared with the M2 group, CD206 expression decreased in the HQJZ+M2 group (P<0.05), CD86 expression increased significantly (P<0.01). In vivo, Real-time PCR results showed that, compared with the control group, CD86 and CD206 expression levels were significantly increased in the model group (P<0.01). Compared with the model group, CD206 expression in the MPA group was significantly decreased (P<0.01). In the HQJZ group, CD206 was significantly decreased (P<0.01). WB results showed that, compared with the model group, protein expression of UCP1 and PPARγ was significantly reduced in the HQJZ group (P<0.05, P<0.01). micro-CT results showed that the total white fat volume in the HQJZ group was greater than that in the model group (P<0.05). HE staining results showed that pathological scores in the HQJZ group were lower than those in the model group (P<0.05). ConclusionHQJZ may inhibit white adipose tissue browning by promoting macrophage M1 polarization and suppressing M2 polarization, thereby delaying fat consumption in CC mice.

ObjectiveTo investigate the migration and distribution characteristics of chemical constituents in blood and hippocampal tissues before and after vinegar processing of Citri Reticulatae Pericarpium Viride(CRPV), and to explore the potential material basis and mechanisms underlying their regulatory effects on emotional disorders by comparing the effects of raw and vinegar-processed products of CRPV. MethodsUltra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS) was employed to characterize and identify the chemical constituents of raw and vinegar-processed products of CRPV extracts, as well as their migrating components in blood and hippocampal tissues after oral administration. Reference standards, databases, and relevant literature were utilized for compound annotation, with data processing performed using PeakView 1.2 software. Seventy male C57BL/6 mice were randomly divided into seven groups, including the blank group, model group, diazepam group(2.5 mg·kg-1), raw CRPV low/high dose groups(0.6, 1.2 g·kg-1), and vinegar-processed CRPV low/high dose groups(0.6, 1.2 g·kg-1), with 10 mice per group. Except for the blank group, all other groups underwent chronic restraint stress(2 h·d-1) for 20 d. Each drug-treated group received oral administration at the predetermined dose starting 10 d after modeling, with a total treatment duration of 10 d. Following model-based drug administration, mice underwent open-field, forced swimming, and elevated plus maze tests. After anesthesia with isoflurane, whole brains were collected from each group of mice, and hippocampi were dissected. Reactive oxygen species(ROS) level in hippocampal tissues was quantified by enzyme-linked immunosorbent assay(ELISA). Hematoxylin-eosin(HE) staining was used to observe hippocampal tissue morphology. Immunofluorescence was performed to detect neuronal nuclei(NeuN) and peroxisome proliferator-activated receptor alpha(PPARα) expressions in hippocampal tissue. Then, pharmacodynamic evaluations were conducted to assess the effects of raw and vinegar-processed CRPV on mood disorders, exploring the potential mechanisms. ResultsVinegar processing caused significant changes in the chemical composition of CRPV, with 18 components showing increased relative content and 35 components showing decreased relative content. The primary changes occurred in flavonoid compounds, including 20 flavonoids, 20 flavonoid glycosides, 3 triterpenes, 3 phenolic acids, 1 alkaloid, and 6 other compounds. Twenty-one components were detected in blood(15 methoxyflavones, 4 flavonoid glycosides, and 2 phenolic acids), with 17 shared between raw and vinegar-processed CRPV. Seven components reached hippocampal tissues(all common to both forms). In regulating emotional disorders, Vinegar-processed CRPV exhibited superior antidepressant-like effects compared to raw products. HE staining revealed that both treatments improved hippocampal neuronal morphology, particularly in the damaged CA1 and CA3 regions. Immunofluorescence and ELISA analyses demonstrated that both raw and vinegar-processed CRPV significantly modulated NeuN and PPARα expressions in hippocampal tissue while alleviating oxidative stress induced by excessive ROS(P<0.05). ConclusionThe chemical composition of CRPV undergoes changes after vinegar processing, but the migrating components in blood and hippocampus are primarily methoxyflavonoids. These components may serve as the potential material basis for activating the PPARα pathway, thereby negatively regulating ROS generation in the hippocampus, reducing oxidative stress, and promoting the development of NeuN-positive neurons. These findings provide experimental evidence for enhancing quality standards, pharmacodynamic material research, and active drug development of raw and vinegar-processed CRPV.

Objective To systematically analyze the literature characteristics of Journal of Organ Transplantation since its inception. Methods Using the China National Knowledge Infrastructure (CNKI) academic journal full-text database as the data source, all articles published in the Journal of Organ Transplantation from January 2010 to August 2025 were retrieved. After excluding non-academic papers, a total of 1 568 research papers were included. R language 4.3.0, Bibliometrix package 3.2.1, and Citespace software were used to analyze the number of publications, publishing institutions, authors, keywords and other aspects. Results The number of publications in Journal of Organ Transplantation increased from an average of 82 articles per year in the early years after its inception to 113 articles per year in recent years, a growth of 37.8%. The geographical distribution of publishing institutions covers 32 provinces, cities and autonomous regions nationwide, mainly concentrated in the South China, East China and North China regions, and has now basically covered the central and western regions in recent years. The author collaboration network includes 45 authors distributed across 7 major collaboration clusters, forming a stable multi-level national research system centered on key university-affiliated hospitals. The high-frequency keywords are dominated by "liver transplantation" (425 times) and "kidney transplantation" (396 times). The theme evolution shows a clear three-stage characteristic: initially focusing on clinical technology application, deepening to immune mechanism exploration in the middle stage, and recently (since 2022) focusing on cutting-edge research areas such as xenotransplantation. Conclusions Journal of Organ Transplantation has witnessed the rapid development of China's organ transplantation cause, fully reflecting the research status and trends in China's organ transplantation field, and has provided an important platform for the future development and international cooperation in China's organ transplantation field.

Objective:
To investigate the trend in disease burden of asthma attributable to tobacco in China from 1990 to 2021, so as to provide the basis for improving intervention measures of asthma.
Methods:
Data on asthma-related mortality and disability-adjusted life years (DALY) attributable to tobacco among adults aged ≥30 years in China from 1990 to 2021 were collected from the Global Burden of Disease (GBD) 2021 database. Age-standardized mortality and age-standardized DALY rate were calculated using the GBD world standard population structure to analyze the tobacco-attributable asthma burden. The average annual percent change (AAPC) was employed to evaluate temporal trends in the age-standardized mortality and DALY rate from 1990 to 2021.
Results:
In China, the age-standardized mortality and age-standardized DALY rate of asthma attributable to tobacco decreased from 0.73/100 000 and 22.20/100 000 in 1990 to 0.17/100 000 and 6.64/100 000 in 2021, showing downward trends (AAPC=-4.603% and -3.888%, both P<0.05). Among males, the tobacco-attributable age-standardized mortality and age-standardized DALY rate declined from 1.44/100 000 and 41.05/100 000 in 1990 to 0.36/100 000 and 12.79/100 000 in 2021 (AAPC=-4.369% and -3.810%, both P<0.05). Among females, the corresponding rates decreased from 0.21/105 and 5.37/105 to 0.03/105 and 1.08/105 (AAPC=-6.074% and -5.074%, both P<0.05). In 2021, males had higher tobacco-attributable age-standardized mortality and age-standardized DALY rate for asthma than females. Both the mortality and DALY rate of asthma attributable to tobacco increased with age, peaking in the age group ≥80 years at 7.84/100 000 and 112.07/100 000, respectively.
Conclusion
From 1990 to 2021, the disease burden of asthma attributable to tobacco showed a declining trend in China, with males and elderly population aged ≥80 years bearing a relatively heavier disease burden.

Chinese Journal of School Health 2026;47(1):70-74
Objective:
To understand the impact of childhood trauma on psychological distress among upper grade elemetary school students, and to explore the mediating role of leisure activities in the relationship, so as to provide a basis for developing mental health intervention strategies.
Methods:
From August to November 2024, a combination of convenience sampling and stratified cluster random sampling was employed to recruit 1 373 fourth to sixth grade students from four primary schools in Harbin. The Childhood Trauma Questionnaire(CTQ), a self designed leisure activity scale (including active and passive leisure activities), and the Kessler Psychological Distress Scale (K10) were used to assess childhood trauma experiences, leisure activities, and levels of psychological distress. Spearman correlation analysis and linear regression analysis were conducted to explore the relationships among childhood trauma, leisure types, leisure time, and psychological distress. Based on the mediation analysis framework proposed by Hayes (Model 4), the mediating role of leisure types in the relationship between childhood trauma and psychological distress was examined.
Results:
Totally 19.1% of the upper elemetary school students exhibited psychological distress, while 30.2% had experienced childhood trauma. During school days, 64.6% of the students were reported of having leisure time concentrated between 1 and 5 hours per day, whereas 67.4% reported leisure time exceeding 5 hours per day on weekends. After controlling for potential demographic confounders such as gender, grade, ethnicity, household registration, being an only child, parents educational level, co residence, and whether parents are first time married,linear regression analysis showed that childhood trauma experience had positive predictive effect on psychological distress in upper primary school students( β =0.20, P <0.01). Leisure time showed no statistically significant association with psychological distress, both on school days ( β =-0.58 to -0.56) and weekends ( β =0.26- 0.98 )(all P >0.05). Active leisure activities were negatively associated with psychological distress ( β =-0.20), while passive leisure activities were positively associated with psychological distress ( β =0.29)(both P <0.01). Leisure type partially mediated the relationship between childhood trauma and psychological distress, accounting for 11.7% of the indirect effect.
Conclusion
Childhood trauma experiences positively predict psychological distress in upper elementary school students, and affect psychological distress through active leisure and passive leisure.

ObjectiveTo investigate the efficacy of sequential tenofovir alafenamide fumarate (TAF) therapy versus the regimen of entecavir (ETV) combined with TAF in chronic hepatitis B (CHB) patients experiencing low-level viremia (LLV) after ETV therapy, as well as their impact on virologic response, liver and renal function, and blood lipid levels. MethodsA total of 217 CHB patients with LLV after ETV treatment who were admitted to Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from May 2020 to December 2023 were enrolled, and according to the treatment regimen, they were divided into TAF group (180 patients receiving sequential TAF therapy) and combined group (37 patients receiving ETV+TAF therapy). The propensity score matching (PSM) method was used to match the patients at a ratio of 1∶1, and finally 37 patients were included in each group to balance the baseline confounding factors. The two groups were compared in terms of hepatitis B virus DNA (HBV DNA) clearance rate, hepatitis B envelope antigen (HBeAg) clearance rate, liver and renal function parameters (liver stiffness measurement [LSM], platelet count [PLT], aspartate aminotransferase [AST], alanine aminotransferase [ALT], and creatinine [Cr]), blood lipid levels (total cholesterol [TC], triglyceride [TG], high-density lipoprotein cholesterol [HDL-C], and low-density lipoprotein cholesterol [LDL-C]), and the incidence rate of adverse reactions. The independent samples t-test was used for comparison of normally distributed continuous data between two groups, and the paired t-test was used for comparison within each group; the chi-square test was used for comparison of categorical data between groups. ResultsAfter 48 weeks of treatment, compared with the TAF group, the combined group had significantly higher HBV DNA clearance rate (86.49% vs 59.46%, χ²=6.852, P=0.009) and HBeAg clearance rate (59.46% vs 35.14%, χ²=4.391, P=0.036). After treatment, compared with the TAF group, the combined group had significantly lower levels of LSM (7.01±1.50 kPa vs 7.90±1.68 kPa, t=2.404, P=0.019), AST (18.02±2.28 U/L vs 21.12±2.85 U/L, t=5.166, P<0.001), and ALT (19.85±3.86 U/L vs 22.00±3.90 U/L, t=2.383, P=0.020) and significantly higher levels of PLT [(218.35±42.60)×109/L vs (192.82±44.13)×109/L, t=2.532, P=0.014] and Cr (70.92±6.54 μmoL/L vs 67.60±6.13 μmoL/L, t=2.253, P=0.027). After treatment, there was a slight increase in the level of TC in both the TAF group (5.60±0.89 mmol/L vs 5.18±0.85 mmol/L, t=2.076, P=0.041) and the combined group (5.45±0.80 mmol/L vs 5.02±0.83 mmol/L, t=2.269, P=0.026). There was no significant difference in the incidence rate of adverse reactions between the TAF group and the combined group (21.62% vs 18.92%, χ²=0.084, P=0.772). ConclusionFor ETV-treated CHB patients experiencing LLV, compared with sequential TAF therapy, the ETV+TAF combined therapy can effectively increase virologic response rate, alleviate liver fibrosis, and improve liver function, whereas sequential TAF therapy has less impact on renal function. Sequential or combined therapy with TAF may induce a slight increase in the level of TC, which should be taken seriously in clinical practice.

OBJECTIVE To study the ameliorative effect and mechanism of Forsythia suspensa-Lonicera japonica herb pair on acute lung injury (ALI) based on serum exosomal microRNA (miRNA). METHODS The rats were randomly divided into a blank group (normal saline), model group (nomal saline), and F. suspensa-L. japonica herb pair group (2.55 g/kg), with 10 rats in each group. Except for the blank group, the other groups were used to establish an ALI model by intratracheal dripping of 5 mg/ mL lipopolysaccharides. After modeling, each group was given relevant medicine/normal saline intragastrically, once a day, for 3 consecutive days. After the last medication, the pathological status of lung tissue was observed; lung wet-to-dry weight ratio and leukocyte counts in bronchoalveolar lavage fluid (BALF) were determined. The levels of inflammatory factors [tumor necrosis factor-α(TNF-α), interleukin-1β (IL-1β), IL-10] in BALF were determined. Exosomes were isolated from rat serum, and high- throughput sequencing technology was employed to screen differentially expressed miRNA within the exosomes, followed by Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Based on the screened differentially expressed miRNA and the enriched KEGG pathways, in vitro cellular experiments were conducted for validation. RESULTS The animal experimental results demonstrated that after intervention with the F. suspensa-L. japonica herb pair, the wet-to-dry weight ratio, the number of leukocytes in BALF, as well as the levels of TNF-α and IL-1β in BALF of ALI rats were all significantly reduced (P<0.01), while the level of IL-10 was significantly increased (P<0.01). The results of high-throughput sequencing experiments revealed that the F. suspensa-L. japonica herb pair could significantly up-regulate the expressions of miR-345-3p, miR-194-5p, miR-653-5p, and others in exosomes. Among them, the KEGG pathways involved in the target genes of differentially expressed miRNA included the hypoxia-inducible factor-1(HIF-1) signaling pathway, among others. The results of cellular E-mail:huang.haiying@126.com validation experiments showed that overexpressed miR-345-3p could significantly elevate the level of IL-10 in the cell supernatant (P<0.01), while significantly reducing the levels of TNF-α and IL-1β in the cell supernatant, as well as the mRNA and protein expression levels of protein kinase B1, phosphatidylinositol 3- kinase, and HIF-1α (P<0.01). CONCLUSIONS F. suspensa-L. japonica herb pair can alleviate inflammatory responses and thereby exert a therapeutic effect in improving ALI by up-regulating the expression of miR-345-3p in serum exosomes and inhibiting the activity of the HIF-1 signaling pathway.

AIM: To analyze the factors influencing total corneal surgically induced astigmatism(SIA)following implantable collamer lens(ICL)implantation.METHODS:This prospective study enrolled 162 patients(162 eyes)who underwent ICL implantation at our hospital between July 2023 and January 2024. Based on preoperative assessment of anticipated postoperative residual astigmatism, different incisions were selected. Superior incision was selected for patients with expected residual astigmatism with the rule in 75 eyes, and temporal incision was selected for patients with expected residual astigmatism againist the rule in 87 eyes. Parameters including total corneal refractive power, incision length, internal ostium-to-visual axis distance, central corneal thickness, preoperative total corneal astigmatism, and corneal diameter were measured using the Pentacam anterior segment analyzer before and at 3 mo after surgery. Postoperative total corneal SIA was calculated based on the changes in total corneal refractive power. Multiple linear regression analysis was performed to assess the influence of the above parameters on postoperative total corneal SIA.RESULTS:A total of 162 cases(162 eyes)that implanted with ICL were included in the analysis, and 8 cases were lost to follow-up, with a loss rate of 4.9%. Eventually 154 cases(154 eyes)completed the research. The superior incision group comprised 72 cases(72 eyes), including 17 males and 55 females, with a mean age of 25.96±6.17 years, while the temporal incision group comprised 82 cases(82 eyes), including 20 males and 62 females, with a mean age of 27.79±6.47 years. No significant difference in postoperative total corneal SIA was observed between the two groups [0.31(0.21, 0.49)D vs. 0.27(0.13, 0.485)D, P=0.159]. Multiple linear regression analysis revealed that internal ostium-to-visual axis distance and preoperative total corneal astigmatism significantly influenced postoperative total corneal SIA in the superior incision group(P=0.001). The regression equation was: postoperative total corneal SIA=0.71-0.381×internal ostium-to-visual axis distance+0.16×preoperative total corneal astigmatism. No significant influencing factors for postoperative total corneal SIA were identified in the temporal incision group.CONCLUSION: During ICL implantation, the magnitude of total corneal SIA is comparable between superior and temporal incisions. For patients receiving a superior incision, the internal ostium-to-visual axis distance and preoperative total corneal astigmatism value can be used to quantitatively predict postoperative total corneal SIA to a certain extent, thereby aiding in the optimization of postoperative visual quality.

ObjectiveTo investigate the differential expression of integrin alpha-6(ITGA6) in abdominal wall endometriosis (AWE) tissues and its molecular mechanisms in regulating AWE. Methods36 AWE lesions were designated as the experimental group, while 36 cases of normal endometrial tissues served as the controls. Differential expression of ITGA6 between the two groups was assessed through immunohistochemical (IHC) staining. Human ITGA6 gene-specific interference sequences were designed, synthesized, and packaged into lentiviral vectors to establish the Ishikawa cell line with ITGA6-knockdown. Similarly, the ITGA6-overexpression cell line was constructed using the coding sequence (CDS) of the gene. Real-time PCR and Western blot were performed to detect changes in epithelial-mesenchymal transition(EMT)-related markers and angiogenesis-related indicators. Cell invasion and migration capabilities were assessed by Cell Scratch and Transwell assays. Furthermore, Western blot was conducted to profile PI3K/AKT pathway dynamics. ResultsEctopic endometrial tissues exhibited a marked increase in the number of ITGA6-positive cells and their expression intensity compared to eutopic endometrium (each P < 0.001). Compared with the NC group, the ITGA6-knockdown group showed significantly reduced expression of N-cadherin, VEGF, and TGF-β1 (all P < 0.01), while E-cadherin expression was markedly increased (P < 0.01). Concomitantly, the invasion and migration capacities of ITGA6-low expression were significantly impaired (P < 0.001 for both), accompanied by a marked reduction in AKT and phosphorylated AKT(p-AKT) levels (P < 0.001). Conversely, overexpressing ITGA6 resulted in opposite effects. ConclusionITGA6 modulates EMT and angiogenesis in Ishikawa cells via the PI3K/AKT signaling pathway, thereby enhancing cell invasion and migration capabilities, which contributes to the pathogenesis of AWE.
