OBJECTIVES: To investigate the role of ferroptosis in diquat-induced acute kidney injury (AKI) and its molecular mechanisms. METHODS: Transgenic zebrafish models with Tg (Eco.Tshb:EGFP) labeling of the renal tubules and Tg (lyz:dsRed2) labeling of the neutrophils were both divided into control group, gentamicin (positive control) group, diquat poisoning group, ferroptosis inhibitor group. The indicators of kidney injury, inflammatory response, and ferroptosis were examined in the zebrafish, and the changes in expressions of voltage-dependent anion-selective channel protein 1 (VDAC1) and mitochondrial ferritin (FTMT) were detected using Western blotting. RESULTS: AKI induced by diquat exhibited a significant dose-effect relationship, and the severity of injury was proportional to the exposure concentration. Diquat also caused marked oxidative stress and inflammatory responses in the zebrafish models. Rhodamine metabolism assay and HE staining revealed significantly declined glomerular filtration function of the zebrafish as diquat exposure concentration increased. Immunofluorescence staining highlighted significant changes in the expressions of ferroptosis markers GPX4 and FTH1 in zebrafish renal tissues following diquat exposure. In diquat-exposed zebrafish, treatment with ferrostatin-1, a ferroptosis inhibitor, obviously upregulated GPX4 and downregulated FTH1 expressions and improved the metabolic rate of glucan labeled with rhodamine B. Diquat exposure significantly upregulated the expression of VDAC1 and FTMT in zebrafish, and the application of ferrostatin-1 and VBIT-12 (a VDAC1 inhibitor) both caused pronounced downregulation of FTMT expression. CONCLUSIONS Ferroptosis is a critical mechanism underlying diquat-induced AKI, in which VDAC1 and FTMT play important regulatory roles, suggesting their potential as therapeutic target for AKI caused by diquat.

Anxiety disorder is a major symptom of autism spectrum disorder (ASD) with a comorbidity rate of ~40%. However, the neural mechanisms of the emergence of anxiety in ASD remain unclear. In our study, we found that hyperactivity of basolateral amygdala (BLA) pyramidal neurons (PNs) in Shank3 InsG3680 knock-in (InsG3680^+/+) mice is involved in the development of anxiety. Electrophysiological results also showed increased excitatory input and decreased inhibitory input in BLA PNs. Chemogenetic inhibition of the excitability of PNs in the BLA rescued the anxiety phenotype of InsG3680^+/+ mice. Further study found that the diminished control of the BLA by medial prefrontal cortex (mPFC) and optogenetic activation of the mPFC-BLA pathway also had a rescue effect, which increased the feedforward inhibition of the BLA. Taken together, our results suggest that hyperactivity of the BLA and alteration of the mPFC-BLA circuitry are involved in anxiety in InsG3680^+/+ mice.

Chronic pain, frequently comorbid with neuropsychiatric disorders, significantly impairs patients' quality of life and functional capacity. Accumulating evidence implicates the chemokine CCL2 and its receptor CCR2 as key players in chronic pain pathogenesis. This review examines the regulatory mechanisms of the CCL2/CCR2 axis in chronic pain processing at three hierarchical levels: (1) Peripheral Sensitization: CCL2/CCR2 modulates TRPV1, Nav1.8, and HCN2 channels to increase neuronal excitability and CGRP signaling and calcium-dependent exocytosis in peripheral nociceptors to transmit pain. (2) Spinal Cord Central Sensitization: CCL2/CCR2 contributes to NMDAR-dependent plasticity, glial activation, GABAergic disinhibition, and opioid receptor desensitization. (3) Supraspinal Central Networks: CCL2/CCR2 signaling axis mediates the comorbidity mechanisms of pain with anxiety and cognitive impairment within brain regions, including the ACC, CeA, NAc, and hippocampus, and it also increases pain sensitization through the descending facilitation system. Current CCL2/CCR2-targeted therapeutic strategies and their development status are discussed, highlighting novel avenues for chronic pain management.

Objective:To investigate the efficacy of immune checkpoint inhibitor maintenance therapy after radical radiotherapy and chemotherapy for stage Ⅲ-ⅣA esophageal squamous cell carcinoma (ESCC) in the real world.Methods:The clinical data of 65 patients with stage Ⅲ-ⅣA ESCC treated by radical radiotherapy and chemotherapy from January 1, 2018 to December 31, 2022 in Hefei Cancer Hospital, Chinese Academy of Sciences were retrospectively analyzed. According to whether to undergo immune checkpoint inhibitor maintenance therapy after radical radiotherapy and chemotherapy, the patients were divided into a control group ( n=29) and an immune maintenance therapy group ( n=36) . The objective response rate (ORR) , progression-free survival (PFS) , and overall survival (OS) between the two groups were compared. Kaplan-Meier method was used to draw the survival curve accompanied with log-rank test. Cox regression model was used to conduct both univariate and multivariate analyses. Results:The ORR was 34.5% (10/29) in the control group and 61.1% (22/36) in the immune maintenance therapy group, with a statistically significant difference ( χ2=4.56, P=0.032) . The median PFS of control group and immune maintenance therapy group were 7.2 and 17.9 months, respectively, with a statistically significant difference ( χ2=7.86, P=0.005) . The median OS was 14.1 and 27.8 months, respectively, with a statistically significant difference ( χ2=5.40, P=0.020) . Univariate analysis showed that, objective response ( HR=0.09, 95% CI: 0.03-0.28, P<0.001) and immune maintenance therapy ( HR=0.38, 95% CI: 0.17-0.88, P=0.024) were the influential factors of OS in ESCC patients treaded by radical chemoradiotherapy in stage Ⅲ-ⅣA. Multivariate analysis showed that, objective response ( HR=0.09, 95% CI: 0.03-0.29, P<0.001) and immune maintenance therapy ( HR=0.40, 95% CI: 0.17-0.92, P=0.032) were the independent influencing factors for OS in ESCC patients treaded by radical chemoracial therapy in stage Ⅲ-ⅣA. The incidence of adverse reactions was 22.22% (8/36) in the immune maintenance therapy group and 10.34% (3/29) in the control group, with no statistically significant difference ( χ2=1.61, P=0.204) . All the adverse reactions were grade 1-2, and the symptoms were relieved after symptomatic treatment. Conclusion:Maintenance therapy with immune checkpoint inhibitors after radical chemoradiotherapy of stage Ⅲ-ⅣA ESCC can significantly improve the prognosis of patients with good safety.

As people's living standards improve， the development trend of diabetes has gradually become severe. Diabetes is a chronic inflammatory disease associated with abnormal expression of nuclear factor-kappa B （NF-κB） in patients. NF-κB exists in various tissue cells and participates in the regulation of a variety of genes related to immune function and inflammation. Varieties of factors can activate NF-κB when the body is stimulated by external factors， so as to produce inflammation and other reactions. Previous studies on NF-κB mainly focus on cancer， and the pathological mechanism of the treatment of diabetes by related signaling pathways and the progress of traditional Chinese medicine （TCM） treatment have not been systematically elaborated on. By referring to the relevant literature in China and abroad， it was found that NF-κB is not isolated in the development and progression of diabetes but is associated with signal molecules related to inflammation， oxidative stress， and energy metabolism， and it is involved in mediating inflammation， pancreatic β cell apoptosis， insulin signal transduction， and other physiological functions. Therefore， blocking the transmission of NF-κB signaling pathway is beneficial to the treatment of diabetes. At present， Western medicine for the treatment of diabetes mainly includes oral hypoglycemic drugs and insulin injections， but the adverse reactions are obvious. TCM has been characterized by multi-target， extensive action， and excellent curative effects in the treatment of diabetes. TCM and its compounds with functions of tonifying Qi and promoting blood circulation， regulating qi and eliminating phlegm， clearing heat and detoxifying， and nourishing Yin and moistening dryness can effectively intervene in the abnormal expression of NF-κB signaling pathway in vivo through anti-inflammatory effects. In this paper， the association between NF-κB signaling pathway and diabetes was summarized， and the modern research progress of TCM intervention of NF-κB signaling pathway in the treatment of diabetes in the past five years was reviewed， so as to lay a laboratory foundation for the study of a new pathological mechanism of diabetes based on NF-κB signaling pathway and provide new targets and research direction for the prevention and treatment of diabetes and development of related TCM.

Objective: To investigate the second-hand smoke behavior at home among smokers, so as to provide the reference for developing home tobacco control strategies. Methods: Permanent residents who were smokers and at the ages of 15 years and above were sampled from 10 streets (townships) in Xuhui District, Shanghai Municipality using the multi-stage random sampling and population-size proportional sampling methods in 2022. Demographic information, smoking status, awareness of second-hand smoke hazards and second-hand smoke behavior at home were collected by questionnaire surveys. Factors affecting second-hand smoke behavior at home were identified using a multivariable logistic regression model. Results: A total of 1 024 smokers were surveyed, including 769 males (75.10%) and 255 females (24.90%). The awareness of hazards of second-hand smoke was 33.59%; the awareness rate of second-hand smoke causing lung cancer in adults was the highest at 76.76%, while the awareness rate of second-hand smoke leading to premature birth and low birth weight in newborns was the lowest at 39.45%. There were 459 smokers with second-hand smoke behavior at home, accounting for 44.82%. Multivariable logistic regression analysis showed that occupation (the retired, OR=2.320, 95%CI: 1.276-4.218), frequency of smoking (often, OR=5.722, 95%CI: 3.977-8.231), smoking duration (a year and above, OR=10.089, 95%CI: 5.508-18.480), electronic cigarette use (occasionally, OR=2.994, 95%CI: 1.283-6.986), living with pregnant women or infants (no, OR=2.171, 95%CI: 1.367-3.448), family indoor smoking restrictions (no restriction, OR=13.926, 95%CI: 7.538-25.727) and awareness of second-hand smoke hazards (unknown, OR=1.562, 95%CI: 1.067-2.287) were the influencing factors for second-hand smoke behavior at home. Conclusion There were 44.82% smokers in Xuhui District with second-hand smoke behavior at home, which was influenced by occupation, living situation, smoking status, family indoor smoking restriction and awareness of second-hand smoke hazards.

Objective:To detect itching,anxiety,depression behaviors in chronic itch models of mice and observe the activation of γ-aminobutiric acid(GABA)neurons in the ventral sector of the zona incerta(ZIv),and provide mor-phological evidence for their involvement in the modulation of itch information.Methods:Diphenylcyclopropenone(DCP)was used in glutamic acid decarboxylase 67-green fluorescent protein(GAD67-GFP)knock-in mice to establish chronic itch model.Itch behaviors were detected by video tracking system to verify whether the models were successfully established.The anxiety,depression behaviors of chronic itch model mice were detected by using elevated plus maze test(EPM)and tail suspention test(TST).By using GAD67-GFP mice,the distribution of GABAergic neurons in va-rious sectors of the zona incerta(ZI)was observed.And combined with immunofluorescence staining method,double labeling of GABAergic neurons with FOS in ZIv were observed respectively in control and DCP group mice.Results:In brain slices of GAD67-GFP mice,GABAergic neurons can be observed within all sectors of ZI and are more concentrat-ed in ZIv.Compared with control group mice,DCP group mice showed a significant increase in the bouts of scratching(P＜0.001).The time of immobility in TST was significantly higher in DCP group mice than in control group mice,which displayed depression-like behavior.The EPM test showed that the numbers of entries and proportion of time in the cross region in DCP group mice were less than in control group mice.EPM test revealed that DCP group mice exhibited anxiety-like behavior.The results of immunofluorescence staining showed that the number of FOS-positive cells in ZIv was significantly higher in DCP group mice than in control group mice,and abundant co-labeled neurons of FOS and GABAergic neurons were observed in ZIv.Conclusion:GABAergic neurons were predominantly distributed in ZI,and were more concentrated in ZIv.The activation of GABAergic neurons in ZIv of DCP group mice provides morphological evidence on the involvement of GABAergic neurons in chronic itch and associated negative emotions.
