Attention deficit hyperactivity disorder （ADHD） is often accompanied by tic disorder. The core pathogenesis is considered to be ministerial fire scorching yin and internal stirring of deficient wind， which leads to disharmony between the body and spirit， resulting in clinical manifestations. The treatment principles emphasize nourishing yin fluids， calming ministerial fire， and extinguishing endogenous wind （内风）. The method of nourishing yin fluids is applied throughout the entire treatment process， commonly using ingredients such as Shudihuang （Rehmanniae Radix Praeparata）， Shanzhuyu （Corni Fructus）， Gouqizi （Lycii Fructus）， Wuweizi （Schisandrae Chinensis Fructus）， and Tusizi （Cuscutae Semen）. These are combined with approaches to harmonize the zang-fu organs， primarily including extinguishing liver wind， clearing heart fire， nourishing kidney water， and strengthening spleen earth， thereby stabilizing ministerial fire and extinguishing endogenous wind. Additionally， emotional regulation and smoothing emotional constraint are essential to improve clinical symptoms in children with ADHD comorbid with tic disorder.

IgA nephropathy (IgAN) is the most common primary glomerulonephritis worldwide and a major cause of chronic kidney disease and kidney failure. IgAN exhibits marked heterogeneity in clinical presentation, histopathology, and pathogenic mechanisms, contributing to variable treatment responses and prognosisamong patients. Precise risk assessment and individualized intervention are therefore of critical importance. This review systematically traces the evolution of IgAN management from traditional risk stratification toward biomarker-driven precision medicine. We first review the clinical utility and limitations of established risk stratification tools, including the KDIGO guidelines, the Oxford MEST-C classification, and the International IgAN Prediction Tool. We then discuss emerging biomarkers closely linked to disease pathogenesis, including galactose-deficient IgA1 (Gd-IgA1), anti-Gd-IgA1 autoantibodies, B cell activating factor (BAFF), a proliferation-inducing ligand (APRIL), and complement components, as well as the targeted therapies they have informed. In addition, urinary biomarkers and multi-omics approaches show promise for dynamic disease monitoring and individualized risk stratification.

AIM: To investigate the correlation between serum Sestrin 2(SESN2), signal peptide, CUB and EGF-like domain-containing protein 1(SCUBE-1), and longpentraxin 3(PTX3)levels, with disease severity and prognosis in patients with diabetes macular edema(DME). METHODS:Prospective study. The study included DME patients who were treated at the hospital between January 2023 and October 2024, as well as patients with type 2 diabetes mellitus(T2DM)and healthy individuals who underwent physical examinations during the same period. Serum levels of SESN2, SCUBE-1, and PTX3 were measured using the ELISA method. Factors influencing poor prognosis in DME patients were analyzed. RESULTS:This study included a total of 114 eye from 114 DME patients, For unilateral disease, the affected eye was enrolled; for bilateral disease, the more severely affected eye was selected for enrollment.(72 men and 42 women, with a mean age of 56.94±7.38 y), 114 T2DM patients(65 men, 49 women, mean age 56.18±7.22 y), and 114 healthy individuals(77 men, 37 women, mean age 56.33±7.26 y). There were no cases of loss to follow-up. FPG and HbA1c levels in the DME and T2DM groups were significantly higher than those in the healthy group(all P<0.05). Serum SESN2 levels decreased progressively from the healthy group to the T2DM group to the DME group, while SCUBE-1 and PTX3 levels increased progressively(all P<0.05). DME patients were classified by disease severity into a mild group of 23 cases(14 men, 9 women, mean age 55.81±7.52 y), a moderate group 54 cases(35 males, 19 females, mean age 56.97±7.35y), and a severe group 37 cases(23 males, 14 females, mean age 57.60±7.41 y). Serum SESN2 levels decreased progressively from the mild to the moderate and to the severe group, while SCUBE-1, PTX3, and CST levels increased progressively(all P<0.05). Serum SESN2 levels were negatively correlated with DME severity and CST, whereas SCUBE-1 and PTX3 levels were positively correlated with both DME severity and CST(all P<0.001). Among the 114 DME patients, 81 were in the favorable prognosis group and 33 were in the unfavorable prognosis group. In the poor prognosis group, serum SESN2 levels were lower than those in the favorable prognosis group, while SCUBE-1 and PTX3 levels were higher(all P<0.05). Low serum SESN2 levels, high SCUBE-1 levels, and high PTX3 levels were factors associated with poor prognosis in DME patients(all P<0.05). The AUC(0.916)for the combined prediction of poor prognosis in DME patients using serum SESN2, SCUBE-1, and PTX3 levels was higher than that for each marker individually(0.780, 0.782, and 0.783, respectively, all P<0.05). CONCLUSION:Serum SESN2 levels are reduced in DME patients, while SCUBE-1 and PTX3 levels are elevated. Changes in these three markers are associated with disease severity and prognosis, and the combined detection has high predictive value for poor patient outcomes.

Background: Malignant pleural effusion (MPE), a common complication of advanced cancers, is associated with poor prognosis and reduced quality of life. Although host–tumor interactions are known to drive MPE development, the associated immune dynamics during disease progression remain unclear. Using a Lewis lung carcinoma-induced MPE model in C57BL/6JNidfc mice, we systematically evaluated general parameters and immune cell changes at two-day intervals throughout disease progression. Results: The day of Lewis lung carcinoma cell injection into the pleural space was designated as day 0. By day 10 post-injection (p.i.), MPE-bearing mice exhibited ~ 10% body weight loss, marking the experimental endpoint. Pleural tumor mass and pleural effusion volume were minimal up to day 4 p.i. but increased sharply from day 6 onward.CD45⁺ immune cell counts rose over time, and days 6, 8, and 10 p.i. marked key stages of MPE progression. On day 6, B cells, T cells, and natural killer cells, but not macrophages and neutrophils, increased significantly compared to earlier timepoints. By day 8, all immune cell subsets except T cells exceeded day 6 levels, and at day 10, natural killer cell numbers declined while others continued to increase. Besides, the numbers of CD8⁺ T cells, Th1 cells, regulatory T cells, and M2 macrophages progressively increased from day 6 to 10. Based on these data, days 6 and 10 were defined as early and advanced MPE stages, respectively, with distinct immune phenotypes. In advanced MPE, CD8⁺ T cells displayed reduced IFN-γ, TNF-α, Granzyme B, Perforin, FasL, and Ki-67, but upregulated PD-1 and CTLA-4 relative to early stage. Similarly, Th1 cells showed decreased IFN-γ, TNF-α, and IL-2 production along with reduced Ki-67 expression. Advanced-stage M2 macrophages exhibited lower MHC-II levels and impaired phagocytosis, but higher PD-L1 and IL-10 production, while neutrophils showed reduced TNF-α release and phagocytic activity. Conclusions Our findings characterize the temporal immune dynamics associated with MPE progression in a mouse model, revealing a transition from an early immunostimulatory state to a late immunosuppressive state. This study enhances our understanding of MPE immunopathogenesis and provides a foundation for developing precise, stagespecific therapeutic strategies.

Objective: To systematically evaluate the influencing factors for autism spectrum disorder (ASD) in Chinese children, so as to provide the evidence for risk prediction and intervention of ASD. Methods: The publications pertaining to the influencing factors for ASD in Chinese children were retrieved from CNKI, Wanfang Data, VIP, PubMed and Embase database from inception to August 2024. A meta-analysis was performed using R package version 4.4.1. Sensitivity analysis was performed using the "leave-one-out" evaluation procedure. Publication bias was assessed using Egger regression test. Results: A total of 38 high-quality articles out of 9 015 articles were finally included, covering 149 607 individuals, with 5 974 cases of ASD. The meta-analysis showed that demographic factors including family history of related diseases (OR=14.958), maternal age of ≥35 years (OR=2.287) and parental history of hazardous occupations (OR=3.511); pregnancy-related factors including history of abortion (OR=5.832), no folate supplementation before and during pregnancy (OR=4.566), tobacco exposure before and during pregnancy (OR=2.596), history of other adverse exposures before and during pregnancy (OR=3.533), history of infectious diseases during pregnancy (OR=3.753), history of non-infectious diseases during pregnancy (OR=2.563), psychological problems during pregnancy (OR=3.864), history of medication during pregnancy (OR=6.651), adverse environmental exposures during pregnancy (OR=3.754), severe pregnancy reactions (OR=5.082), abnormal perinatal period (OR=2.987), cesarean delivery (OR=1.659), other perinatal adverse factors (OR=3.856), history of neonatal asphyxia (OR=2.792) and neonatal jaundice (OR=3.687); parenting factors including non-exclusive breastfeeding (OR=2.510), early/excessive screen exposure (OR=3.589) and feeding problems (OR=3.113); and individual factors including being male (OR=3.333) and history of convulsions/epilepsy (OR=7.035) were influencing factors for ASD in Chinese children. Conclusions The prevalence of ASD in Chinese children is primarily associated with 23 influencing factors, including family history of related diseases, history of abortion, no folate supplementation before and during pregnancy, medication during pregnancy, early/excessive screen exposure and history of convulsions/epilepsy.

BACKGROUND:Immunosuppression leads to impaired body immune function and aggravates the disease.Herb-partitioned moxibustion can effectively regulate immune function and improve immunity in the body,but its regulatory mechanism has not been elucidated. OBJECTIVE:To sequence immunosuppressed model rats treated with herb-partitioned moxibustion using bioinformatics techniques based on transcriptomics and to explore the mechanisms by which it regulates immunity. METHODS:Twenty-four Sprague-Dawley rats were randomly assigned to three groups:control,model,and herb-partitioned moxibustion groups,with eight rats in each group.The model and herb-partitioned moxibustion groups were subjected to establishment of an immune suppression model by intraperitoneal injection of cyclophosphamide at a dose of 35 mg/kg for 3 consecutive days.No interventions were administered to the control and model groups after modeling.In contrast,the herb-partitioned moxibustion group received moxibustion treatment at Zhongwan,Shenque,Guanyuan,and Zusanli acupoints using a combination of moxa and herbal cakes,once a day,for 10 consecutive days,with samples being collected the day after the end of the intervention.Peripheral blood was collected from all groups of rats to measure their white blood cell count.RNA-seq was performed on the Illumina sequencing platform,and differentially expressed genes were selected for bioinformatics analysis using the GO and KEGG databases. RESULTS AND CONCLUSION:Compared with the control group,the model group exhibited a significant decrease in white blood cell count(P<0.001).RNA-seq analysis identified 3 026 differentially expressed genes between the model and control groups,with 1 565 upregulated and 1 461 downregulated.There were 535 differentially expressed genes identified between the herb-partitioned moxibustion group and the model group,with 280 upregulated and 255 downregulated.The Venn diagram analysis revealed that 159 genes were downregulated in the model group compared with the control group.However,after moxibustion with herbal cakes,these genes were upregulated.Protein-protein interaction network analysis identified 10 core targets,including Oasl,Oas2,Isg15,Herc6,Mx2,Helz2,Mx1,Syk,Hspa1a,and Ret.According to GO and KEGG analyses,moxibustion with herbal cakes regulated the body through pathways related to immune response,viruses,angiogenesis,and the autoimmune system.To conclude,there is a significant association between herbal cake-separated moxibustion intervention and immune suppression targets,including Oasl,Oas2,Isg15,Herc6,Mx2,Helz2,and Mx1.The intervention exhibits regulatory effects in the pathways related to immune responses,viral activities,and angiogenesis.

Objective:To investigate the application value of dual-layer detector spectral CT in the precise outlining of gross tumor volume (GTV) in lung cancer patients.Methods:Imaging data of 39 patients with pathologically confirmed lung cancer on dual-energy enhanced CT scans in Hebei Medical University Third Hospital were retrospectively analyzed. Among them, 13 patients were not complicated with lung atelectasis and 26 cases were complicated with lung atelectasis and 9 of them received positron emission computed tomography (PET-CT) scan. The virtual single-energy images of arterial and venous dual-phase 40 keV images were reconstructed with the spectral base images of Iqon dual-energy CT, and the GTV of the primary foci was outlined using the reconstructed images and conventional enhanced CT images. The GTV outlined by conventional enhanced CT image, 40 keV virtual monoenergetic (VM) CT image, 40 keV VM-iodine density (VM-ID) fusion image in the arterial phase, conventional enhanced CT image, 40 keV VM image and 40 keV VM-ID image in the venous phase and PET-CT image was defined as GTV ACT, GTV A40VM, GTV A40VMID, GTV VCT, GTV V40VM, GTV V40VMID and GTV PET-CT, respectively. The consistency of target area outlining was assessed by calculating the GTV volume, the Dice similarity coefficient (DSC), and the 95 th percentile of the Hausdorff distance (HD95). Pairwise comparison among groups was conducted by Friedman test and corrected by Bonferroni correction. Results:In GTV comparisons, the differences in GTV ACT, GTV VCT, GTV A40VM and GTV V40VM in patients without pulmonary atelectasis were not statistically significant ( χ2=1.89, P=0.595). The DSC and HD95 of GTV ACTvs. GTV A40VM were 0.96 and 3.00, and the DSC and HD95 of GTV VCTvs. GTV V40VM were 0.94 and 2.93, respectively. The differences in GTV ACT, GTV A40VM, GTV A40VMID, GTV VCT, GTV V40VM, GTV V40VMID and GTV PET-CT in patients complicated with pulmonary atelectasis were statistically significant (all P<0.001). Pairwise comparison of Bonferroni correction showed that there was no statistically significant difference in GTV A40VM, GTV A40VMID, GTV V40VM, GTV V40VMID and GTV PET-CT (all P=1.000), all of which were significantly smaller than those of GTV ACT and GTV VCT (both P=0.001), and there was no statistically significant difference between GTV ACT and GTV VCT (both P=1.000). Based on the tumor extent shown by PET-CT (standardized uptake value =2.5), DSC were slightly higher and HD95 were slightly lower than conventional enhanced CT of GTV A40VM, GTV V40VM, GTV A40VMID, GTV V40VMIDvs. GTV PET-CT, respectively. When the arterial phase sequences were compared with PET-CT, pairwise comparison of Bonferroni correction showed that the DSC and HD95 of GTV A40VMvs. GTV PET-CT and GTV ACTvs. GTV PET-CT were statistically significant (both P<0.01), and the differences were not statistically significant among the remaining groups (all P>0.05). When intravenous phase sequences were compared with PET-CT, pairwise comparison of Bonferroni correction revealed that the DSC and HD95 of GTV V40VMIDvs. GTV PET-CT and GTV VCTvs. GTV PET-CT were statistically significant (both P<0.01), and the differences were not statistically significant among the remaining groups (all P>0.05). Conclusions:The use of 40 keV VMI-ID fusion images to outline the target area of the primary tumor lesions is closer to that of PET-CT, which provides a novel option for the precise outlining of the target area of clinical radiotherapy.

ObjectiveTo study the mechanism of Huanglian Jiedutang （HLJDT） in treating mice with atherosclerosis （AS） by improving ferroptosis. MethodsA total of 10 SPF C57BL/6J mice were selected as a normal group， and 50 ApoE^-/- mice were randomly divided into five groups： model group， low-dose group of HLJDT， medium-dose group of HLJDT， high-dose group of HLJDT， and atorvastatin （ATV） group. ApoE^-/- mice were fed a high-fat diet for eight weeks to establish the AS model， and at the 9th week， they were given normal saline， low， medium， and high doses of HLJDT （3.9， 7.8， 15.6 g·kg^-1·d^-1）， and atorvastatin calcium tablets （0.01 g·kg^-1·d^-1）， respectively， for a total of eight weeks. The formation of aortic plaque in mice was observed by gross oil red O staining and Masson staining. The levels of total cholesterol （TC）， low-density lipoprotein cholesterol （LDL-C）， triglyceride （TG）， and high-density lipoprotein cholesterol （HDL-C） in blood fat were measured by the automatic biochemical analyzer， and the mitochondrial structure of the aorta was observed by transmission electron microscopy. The content of serum superoxide dismutase （SOD） in serum was detected by enzyme-linked immunosorbent assay （ELISA）. The content of reduced glutathione （GSH） in serum was detected by the microplate method， and that of malondialdehyde （MDA） in serum was detected by the TBA method. The protein expression of nuclear factor E₂-associated factor 2 （Nrf2）/glutathione peroxidase 4 （GPX4） signaling pathway was detected by Western blot. ResultsCompared with those of the normal group， the contents of TC， LDL-C， TG， HDL-C， and MDA in the serum and the aortic vascular plaque deposition of the model group were significantly increased （P<0.01）， while the expression levels of SOD and GSH in serum， as well as Nrf2， solute carrier family 7 member 11 （SLC7A11）， and GPX4 in aorta were significantly decreased （P<0.01）. Mice in the model group appeared mitochondrial fragmentation and vacuolation in the aorta， volume atrophy， mitochondrial crista reduction， or a loose and disorganized form. Compared with those in the model group， the aortic vascular plaque deposition was significantly decreased in the low-dose， medium-dose， and high-dose groups of HLJDT and ATV group， and the contents of serum TC， LDL-C， TG， and MDA in serum were significantly decreased （P<0.05， P<0.01）. The contents of serum SOD and GSH and the expression levels of Nrf2， SLC7A11， and GPX4 in the aorta were increased （P<0.05， P<0.01）， and the symptoms of aortic mitochondrial vacuolation were alleviated. The number of cristae was increased， and they were ordered neatly. ConclusionHLJDT can reduce aortic vascular plaque deposition， decrease blood lipid and MDA expression， increase SOD and GSH expression， and ameliorate the pathological changes of ferroptosis， the mechanism of which is related to the Nrf2/GPX4 signaling pathway.

ObjectiveTo explore the mechanism of herbal cake-separated moxibustion using the classical formula Xiaoyaosan in alleviating neuroimmune inflammatory responses in chronic fatigue syndrome （CFS） rats， based on the regulation of the toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear transcription factor-κB （NF-κB） signaling pathway. MethodsFifty SPF-grade SD rats aged 6-8 weeks were randomly divided into five groups： Normal group， model group， sham herbal cake moxibustion group， Chinese medicine intragastric administration group， and herbal cake-separated moxibustion group， with 10 rats in each group. Except for the normal group， all other groups underwent a 21-day modeling process， followed by behavioral testing. The herbal cake-separated moxibustion and sham herbal cake moxibustion groups received interventions at the Shenque （CV8）， Guanyuan （CV4）， Zusanli （ST36）， and Qimen （LR14） acupoints. The Chinese medicine intragastric administration group was treated with a Xiaoyaosan suspension via gavage. Behavioral tests were conducted after 10 days of continuous intervention. Serum levels of interleukin （IL）-1β， IL-6， and tumor necrosis factor-α （TNF-α）， as well as hippocampal levels of IL-1β， IL-6， TNF-α， and NF-κB， were detected by enzyme-linked immunosorbent assay （ELISA）. Morphological changes in the hippocampus were observed using hematoxylin-eosin （HE） staining. Real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect mRNA expression levels of TLR4， MyD88， and NF-κB in the hippocampus. Western blot analysis was performed to detect the relative expression levels of TLR4， MyD88， NF-κB， and p65 proteins in the hippocampus. ResultsCompared with the normal group， the model group showed a significant decrease in upright times during the open field test （P<0.01）， as well as significant reductions in total movement distance， resting time， and center region duration （P<0.01）. In the tail suspension test， immobility time increased （P<0.01）， and struggle times decreased （P<0.01）. Serum and hippocampal levels of IL-1β， IL-6， and TNF-α， as well as hippocampal NF-κB levels and TLR4， MyD88， and NF-κB mRNA expression， were significantly elevated （P<0.01）. After treatment， compared with the model group， the total movement distance and upright times in the open field test were significantly increased in all treatment groups （P<0.01）， while resting time and center region duration were notably prolonged （P<0.05， P<0.01）. Immobility time in the tail suspension test was significantly shortened （P<0.01）， and struggle times significantly increased （P<0.05）. Serum and hippocampal levels of IL-1β， IL-6， TNF-α， hippocampal NF-κB levels， and TLR4 and NF-κB mRNA expression were significantly reduced （P<0.05， P<0.01）. Compared with the sham herbal cake moxibustion group， the herbal cake-separated moxibustion group showed a significant extension in center region duration during the open field test （P<0.05） and a significant increase in upright times （P<0.01）. In the tail suspension test， immobility time was reduced （P<0.01）， and struggle times increased （P<0.01）. Serum TNF-α levels in the Chinese medicine intragastric administration group were significantly reduced （P<0.01）， while serum IL-6 levels， as well as hippocampal levels of IL-1β， TNF-α， NF-κB， and TLR4， MyD88， and NF-κB mRNA expression， were significantly decreased in both the Chinese medicine intragastric administration group and the herbal cake-separated moxibustion group （P<0.05， P<0.01）. Compared with the Chinese medicine intragastric administration group， the herbal cake-separated moxibustion group exhibited significantly increased upright times in the open field test （P<0.01）. In the tail suspension test， immobility time was reduced （P<0.01）， and struggle times increased （P<0.01）. Serum IL-1β， hippocampal TNF-α levels， and TLR4， MyD88， and NF-κB mRNA expression were significantly decreased （P<0.05， P<0.01）. ConclusionHerbal cake-separated moxibustion effectively improves fatigue and memory function in CFS rats， regulates neuroimmune inflammatory responses， and its mechanism may be related to the modulation of the TLR4/MyD88/NF-κB signaling pathway.

ObjectiveTo explore the sequential effects of hypoxic exercising on miR-27/PPARγ and lipid metabolism target gene and protein expression levels in the obesity rats’ liver. Methods13-week-old male diet-induced obesity rats were randomly divided into three groups (n＝10): normal oxygen concentration quiet group (N), hypoxia quiet group (H), hypoxic exercise group (HE). Exercise training on the horizontal animal treadmill for 1 h/d, 5 d/week for a total of 4 week, and the intensity of horizontal treadmill training was 20 m/min (hypoxic concentration was 13.6%). Comparison of the weights of perirenal fat and epididymal fat in rats across different groups and calculation of Lee’s index based on body weight and body length of rats in each group were done. And the serum concentrations of total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) levels were detected. RT-PCR and Western Blot were used to detect the levels of miR-27, PPARγ, CYP7A1 and CD36. ResultsHypoxic exercise decreased the expression levels of miR-27 in the obese rats’ liver, however, the expression level of PPARγ was gradually increased. The expression levels of miR-27 in HE group were significantly lower than N group (P<0.05). The expression levels of PPARγ mRNA in N group were significantly lower than H group (P<0.05), especially lower than HE group (P<0.01). The protein expression of PPARγ protein in N group was significantly lower than that other groups (P<0.01). The expression of lipid metabolism-related genes and proteins increased in the obese rats’ liver. The expression of CYP7A1 mRNA in N group was significantly lower than H group (P<0.05), especially lower than HE group (P<0.01). The expression of CYP7A1 protein in the obese rats’ liver in N group was extremely lower than H group and HE group (P<0.01). The protein expression of CD36 in N group was significantly lower than that in HE group (P<0.05). Hypoxia exercise improved the related physiological and biochemical indexes of lipid metabolism disorder. The perirenal fat weight of obese rats in HE group was extremely lower than N group and H group (P<0.01), and the perirenal fat weight in N group was significantly higher than H group (P<0.05). The epididymal fat weight in N group was significantly higher than H group (P<0.05), and extremely higher than HE group (P<0.01). The Lee’s index in HE group was extremely lower than N group and H group (P<0.01). The serum concentration of TC in obese rats in HE group was extremely lower than N group and H group (P<0.01). The serum concentration of TG in HE group was extremely lower than N group and H group (P<0.01). The serum concentration of LDL-C in N group was extremely higher than HE group (P<0.01). The serum concentration of HDL-C in N group was extremely lower than H group (P<0.01). ConclusionHypoxia and hypoxia exercise may negatively regulate the levels of PPARγ by inhibiting miR-27 in the obese rats’ liver, thereby affecting the expression of downstream target genes CYP7A1 and CD36, and promoting cholesterol, fatty acid oxidation and HDL-C transport in the liver, and ultimately the lipid levels in obese rats were improved. The effect of hypoxia exercise on improving blood lipid is better than simple hypoxia intervention.
