Inflammatory diseases (IDs) are a general term of diseases characterized by chronic inflammation as the primary pathogenetic mechanism, which seriously affect the quality of patient′s life and cause significant social and medical burden. Current drugs for IDs include nonsteroidal anti-inflammatory drugs, corticosteroids, immunomodulators, biologics, and antioxidants, but these drugs may cause gastrointestinal side effects, induce or worsen infections, and cause non-response or intolerance. Given the outstanding performance of metal polyphenol network (MPN) in the fields of drug delivery, biomedical imaging, and catalytic therapy, its application in the diagnosis and treatment of IDs has attracted much attention and significant progress has been made. In this paper, we first provide an overview of the types of IDs and their generating mechanisms, then sort out and summarize the different forms of MPN in recent years, and finally discuss in detail the characteristics of MPN and their latest research progress in the diagnosis and treatment of IDs. This research may provide useful references for scientific research and clinical practice in the related fields.

Objective:
To analyze the effects of health literacy on overweight and obesity among primary school students and their parents in terms of salt, oil and sugar reduction (referred to as the "three reductions"), so as to provide a theoretical basis for the development of obesity control measures.
Methods:
From March to April 2024, a total of 1 022 fourthgrade primary school students and 913 parents were surveyed in 24 classes in six counties in Shandong Province using multistage cluster random sampling, and physical measurements of primary school students were conducted. Pearsons correlation analysis and ordered multivariate Logistic regression were used to investigate the associations between health literacy of primary school students and their parents with overweight and obesity among children.
Results:
The detection rates of overweight and obesity primary school students in Shandong Province were 14.87% and 24.66%, respectively, with significant sex difference in obesity rate (29.46% for boys and 19.76% for girls) (χ2=12.93, P<0.01). In addition to students reducing oil scores, parental reducing salt,reducing oil,reducing sugar, comprehensive health literacy scores and students reducing salt,reducing sugar and comprehensive health literacy scores showed a negative relationship with students overweight and obesity (r=-0.10, -0.08, -0.07, -0.10, -0.04, -0.07, -0.03, P<0.05). The overweight and obesity rates among primary school students with high parental reducing salt,reducing oil,reducing sugar and composite health literacy scores were lower (OR=0.69, 0.69, 0.71, 0.63, P<0.05); and the overweight and obesity rate among students with high parental and low parental and high and low parental health literacy scores were lower (OR=0.68, 0.57, P<0.05).
Conclusion
Improving health literacy regarding "three reductions" for parents and children, especially parents, can effectively reduce the risk of childhood overweight and obesity.

ObjectiveTo investigate the potential machanism of Xiaozhong Zhitong Mixture (消肿止痛合剂, XZM) in the treatment of diabetes foot ulcer (DFU). MethodsFifty SD rats were randomly divided into blank group, model group, XZM group, inhibitor group, XZM plus inhibitor group (combination group), with 10 rats in each group. Except for the blank group, rats were fed with high-sugar, high-fat, high-cholesterol diet, intraperitoneally injected with streptozotocin, and subjected to skin defect to establish DFU model. After successful modeling, the XZM group and the combination group were given 1 ml/(100 g·d)of XZM by gavage, while the blank group, model group, and inhibitor group were all given an equal volume of 0.9% sodium chloride injection by gavage. Thirty minutes later, the inhibitor group and the combination group were intraperitoneally injected with 5 mg/(kg·d) of Notch1 inhibitor DAPT. All groups were treated once a day. After 14 days of administration, the skin tissue from the dorsal foot of the blank group rats and wound tissue from the other groups were collected. The pathological changes of granulation tissue in the wound were detected using hematoxylin eosin (HE) staining. The microvascular density (MVD) in wounds was detected through immunohistochemical staining. Real time fluorescence quantitative polymerase chain reaction (RT-PCR) and western blotting were used to detect the mRNA and protein levels of Notch1 homolog (Notch1), Delta-like ligand 4 (Dll4), Delta-like ligand 4 (VEGF), and angiopoietin 2 (Ang-2), respectively. ResultsHistological results showed that the epidermal structure in the dorsal foot skin tissue of the rats in the blank group was intact. In the wound tissue of the model group, the epidermis exhibited excessive keratinization, vacuolar cytoplasm, and a large number of inflammatory cells infiltrating the tissue, while in the XZM group, a large amount of scab formation was observed in the epidermis, with no significant inflammatory cell infiltration and a noticeable increase in fibroblasts. In the combination group and the inhibitor group, partial epidermal scab formation was observed in the wound tissue with a small amount of inflammatory cell infiltration. Compared to those in the blank group, the MVD in the wound tissue increased in the model group, as well as the mRNA expression and protein levels of Notch1 and Dll4, while VEGFA and Ang-2 mRNA expression and protein levels significantly decreased (P<0.05 or P<0.01). Compared to those in the model group, the MVD in the wound tissue of all medication groups significantly increased, and the mRNA and protein levels of Notch1 and Dll4 decreased, while VEGFA and Ang-2 mRNA expression and protein levels increased (P<0.05 or P<0.01). Compared to the XZM group, the inhibitor group and the combination group showed decreased MVD in wound tissue, increased Notch1 and Dll4 mRNA and protein levels, and decreased expression of VEGFA and Ang-2 mRNA and proteins (P<0.05 or P<0.01). ConclusionXZM can effectively promote wound healing in DFU rats, and its mechanism of action may be related to the inhibition of Dll4/Notch1 signaling pathway in the wound tissue, therey promoting angiogenesis.

OBJECTIVE To investigate the inhibitory effects of Ginkgo biloba extract (GBE) on renal inflammation in diabetic nephropathy (DN) model mice, and its potential mechanism. METHODS KK/Ay mice were fed with high fat and high sugar to induce DN model. They were divided into model group, positive control group [metformin 200 mg/(kg·d)], GBE low-dose and high-dose groups [100, 200 mg/(kg·d)], with 6 mice in each group. Six C57BL/6J mice were fed with a regular diet as the control group. Administration groups were given relevant liquid intragastrically, control group and model group were given constant volume of normal saline intragastrically, once a day, for 8 consecutive weeks. The body weight, fasting blood glucose, 24-hour food intake, 24-hour urine output, monocyte chemoattractant protein-1 (MCP-1), interleukin-12 (IL-12), IL-10, advanced glycation end products (AGEs), blood urea nitrogen (BUN) and serum creatinine (Scr) of mice were measured, and the ratio of bilateral kidneys to body weight was also calculated. The pathological injury and fibrotic changes of the renal cortex were observed, and the expressions of macrophage polarization marker proteins [type M1: inducible nitric oxide synthase (iNOS); type M2: arginase-1 (Arg-1)] and AGEs-the receptor of advanced glycation end products (RAGE)/Ras homolog gene pharm_chenjing@163.com family member A (RhoA)/Rho-associated coiled-coil forming protein kinase (ROCK) signaling pathway-related proteins were determined in renal cortex. RESULTS Compared with the model group, the symptoms such as renal cortical hyperplasia, vacuoles, infiltration of inflammatory cells, and renal cortical fibrosis had been improved in GBE low-dose and high-dose groups; body weight, serum level of IL-10, the expression of Arg-1 in the renal cortex were significantly higher than model group (P< 0.01); fasting blood glucose, 24-hour food intake, 24-hour urine output, serum levels of MCP-1, IL-12, BUN, Scr and AGEs, the ratio of bilateral kidneys to body weight, renal injury score, the proportion of renal interstitial fibrosis, the protein expressions of iNOS, RAGE, RhoA and ROCK1 (except for GBE low-dose group) in renal cortex were significantly lower than model group (P<0.01). CONCLUSIONS GBE could improve kidney damage and alleviate inflammatory response in DN model mice, the mechanism of which may be related to inhibiting the AGEs-RAGE/RhoA/ROCK signaling pathway and regulating macrophage polarization.

Objective:
To gain an in depth understanding of the cognitive appraisal of middle school students with mental illness after experiencing childhood trauma, so as to provide a reference for the development of effective interventions.
Methods:
From March to September in 2023, 21 middle school students with childhood trauma experiences and mental illnesses were selected from outpatient and inpatient departments through purposive sampling in a tertiary grade A psychiatric hospital in Wuhan. Semistructured interviews were conducted and the seven steps of Colaizzi phenomenology were used to analyze the data and extract themes.
Results:
A total of 3 themes and 11 subthemes were extracted:insufficient awareness of childhood trauma (lack of selfawareness, lack of awareness of primary caregivers), multiple hurtful experiences after experiencing childhood trauma (complex negative affective experiences, multiple physical discomfort, pessimistic attitudes toward life, social impairment, and academic impairment), and influences on childhood trauma experiences (personality traits, inappropriate personal coping styles, poor upbringing environment, and difficulty in obtaining social support).
Conclusions
Middle school students with mental illnesses and their caregivers generally lack knowledge about childhood trauma, which brings widespread harm and are affected by multiple factors. It should jointly strengthen the popularization of scientific knowledge, intervene in a timely manner, and thereby reduce the adverse consequences of childhood trauma experiences.

AIM:To explore the expression of RhoC in oral squamous cell carcinoma(OSCC)and its effects on the malignant biological behavior of OSCC cells.METHODS:The UALCAN and K-M plotter databases,alongside tis-sue sample analyses,facilitated understanding RhoC expression in cancer and its links to clinicopathological traits.Two small interfering RNAs(RhoC-siRNA)were constructed according to the RhoC gene sequence.The mRNA and protein ex-pression levels of RhoC in OSCC cells were determined.The protein levels of FAK,p-FAK,MAPK,p-MAPK,matrix me-talloproteinase-2(MMP-2)and MMP-9 were also examined by Western blot.Furthermore,the invasion and migration of OSCC cells were analyzed by Transwell assay and scratch test.Finally,the pulmonary metastasis model of nude mice was established.RESULTS:The results of the databases showed that RhoC was highly expressed in OSCC tissues,which was closely related to pathological stage,pathological grade and lymph node metastasis,but not significantly related to the sur-vival rate of patients.Furthermore,compared with paracancer tissues,the mRNA and protein expression levels of RhoC were increased in OSCC tissues(P<0.01).Silencing of RhoC prominently reduced the migration and invasion of OSCC cells as well as the protein levels of p-FAK,p-MAPK,MMP2 and MMP9(P<0.05).The protein levels of MAPK and FAK were unchanged(P>0.05).The fluorescence intensity of the experimental group was significantly lower than that of the control group,and the results of HE staining showed that the number of lung nodules in the experimental group was sig-nificantly reduced(P<0.05).CONCLUSION:RhoC can effectively influence the migration and invasion of OSCC cells,and its potential mechanism may be related to FAK/MAPK/MMPs signaling pathway.
