Diabetic nephropathy（DN） is a common and severe microvascular complication of diabetes. In recent years， the classical herbal formula Shenqi dihuang decoction has demonstrated unique advantages in the clinical treatment of DN. This article conducts a systematic review of the mechanisms of action and clinical applications of Shenqi dihuang decoction in the treatment of DN. It reveals that the mechanism by which this formula improves DN involves multi-target synergistic regulation. For instance, Shenqi dihuang decoction exerts multiple pharmacological effects by regulating signaling pathways including phosphatidy linostiol 3-kinase/protein kinase B， AMP-activated protein kinase/silent information regulator 1/forkhead box O1， and nuclear factor erythroid 2-related factor 2/heme oxygenase-1 pathways.These effects include regulating glucose and lipid metabolism， inhibiting oxidative stress， reducing inflammation， improving insulin resistance， modulating cell death （apoptosis/autophagy/ferroptosis/pyroptosis）， and preventing renal fibrosis. Existing clinical studies indicate that Shenqi dihuang decoction and its modified formulas， alone or in combination with other therapeutic methods， can significantly improve glucose and lipid metabolism， reduce proteinuria， and delay renal function decline in patients with DN. These effects are superior to those of Western medicines such as irbesartan， valsartan， and empagliflozin， and the treatment demonstrates good safety. Future research should leverage systems biology and artificial intelligence technologies to further elucidate the integrated mechanisms in the treatment of DN by Shenqi dihuang decoction， thereby advancing the precision and standardization of its clinical application.

Objective: To investigate the attention cognitive function and symptom correlations of school aged children with attention deficit hyperactivity disorder (ADHD)using event related potential (ERP) technology, so as to provide references for the early diagnosis of children with ADHD. Methods: A total of 52 school aged children diagnosed with ADHD at the outpatient department of the Third Affiliated Hospital of Zhengzhou University from September 2022 to September 2024 and 50 age /sex matched healthy controls were selected. The ERP experiment adopted the auditory Oddball task to conduct comparative analyses of the amplitude and latency of the mismatch negative(MMN) at the Fz, Cz, and Pz points of the scalp electrode and the P3a component respectively. The symptom assessment scales adopted the Swanson,Nolan,and Pelham-Ⅳ Rating Scale (SNAP-Ⅳ) and the Parent Symptom Questionnaire (PSQ), which were filled out by the parents. Spearman correlation analysis was used to analyze the correlation between ERP components and symptoms in schoolaged children with ADHD. Results: The latency of MMN components in the healthy control group on the Fz lead was (188.30±2.06)ms, and the amplitude was (-15.54±1.35)μV; the latency of the P3a component on the Pz lead was (312.82±7.80)ms, and the amplitude was (3.80±0.18)μV. The latency of MMN components in the ADHD group on the Fz lead was (188.94±1.39)ms, and the amplitude was (-14.78±1.40)μV; the latency of the P3a component on the Pz lead was (317.21±5.65)ms, and the amplitude was (3.70±0.13)μV. Compared with normal children, the MMN of children with ADHD had smaller amplitudes in the Fz and Cz leads, and the P3a had greater latency and smaller amplitudes in the Cz and Pz leads ( t =2.79,2.20；-2.04，-3.25；2.35,3.21， P <0.05). Correlation analysis showed that the latency of MMN in children with ADHD was positively correlated with the inattention score in the SNAP-Ⅳ( r =0.22), and the amplitude of MMN was negatively correlated with the inattention score in the SNAP-Ⅳ and the learning problem score in PSQ ( r = -0.26 , -0.34)( P <0.05). The latency of P3a was positively correlated with the scores of inattention in the SNAP-Ⅳ and the score of learning problems in the PSQ ( r =0.26 ,0.24); the amplitude of P3a was negatively correlated with the scores of attention deficit and hyperactivity/impulsivity in the SNAP-Ⅳ and the scores of learning problems and impulsivity/hyperactivity in the PSQ( r = -0.26 , -0.22, -0.25,-0.32)( P <0.05). Conclusions School aged ADHD children exhibit abnormal MMN/P3a components, indicating attention related cognitive dysfunction. Symptoms such as inattention, learning problems and hyperactivity/impulsivity in children with ADHD are related to abnormal components of MMN and P3a.

Objective To investigate the clinical diagnostic value of lung ultrasound(LUS)com-bined with serum interleukin(IL)-1β and IL-12p70 for pediatric community-acquired pneumonia(CAP).Methods A total of 136 pediatric patients with suspected CAP were enrolled and divided in-to CAP group(95 patients)and non-CAP group(41 patients)based on chest computed tomography(CT)results as the gold standard.The LUS characteristics,LUS scores,serum levels of IL-1 β and IL-12p70 were compared between the two groups at admission.Receiver operating characteristic(ROC)curves were plotted to analyze the diagnostic efficacy of LUS combined with serum IL-1 β and IL-12p70 for CAP.Results The incidence rates of interstitial disease,pleural line abnormalities,pleural effusion,lung consolidation,and bronchial signs were higher in the CAP group than those in the non-CAP group(P＜0.05).The serum levels of IL-1 β,IL-12p70 and LUS scores were also high-er in the CAP group than in the non-CAP group(P＜0.05).ROC curve analysis showed that the area under the curve for the diagnosis of CAP using LUS scores combined with serum IL-1 β and IL-12p70 at admission was 0.981,with a sensitivity of 93.68％,a specificity of 95.12％,and a diagnostic effica-cy was significantly higher than that of each index alone(P＜0.05).Conclusion LUS combined with serum IL-1 β and IL-12p70 has high diagnostic value for pediatric CAP.

Asthma is a chronic inflammatory airway disease,and airway inflammation,airway hyper-respon-siveness and airway remodeling are the major pathological alterations in asthma.Numerous studies have demon-strated sphingosine metabolism disorders exist in asthma patients,and sphingosine-1-phosphate(S1P)is the end product of sphingolipid metabolism,which has become the focus of research as an important mediator of immune and inflammatory diseases,and is closely related to the development of asthma.In this paper,we summarize the role of S1P in the pathological changes of asthma from the relationship between S1P and asthma as well as its application in the clinical diagnosis,treatment and efficacy assessment of asthma,with a view to exploring more directions in the diagnosis and treatment of asthma.

Objective This study aimed to identify PAX9 variants in non-syndromic tooth agenesis families of Chi-na,as well as to analyze the genotype-phenotype of non-syndromic tooth agenesis caused by PAX9 variants,which can provide a basis for the genetic diagnosis of tooth agenesis.Methods We collected the data of 44 patients with non-syn-dromic oligodontia who underwent treatment at Stomatological Hospital of Hebei Medical University between 2018 and 2023.Whole-exome sequencing was performed on the peripheral blood of the proband and its core family members,and the variants were verified by Sanger sequencing.Pathogenicity analysis and function prediction of the variants were per-formed using bioinformatics tools.The correlation between the genotype of PAX9 variant and its corresponding pheno-type was examined by reviewing 55 publications retrieved from PubMed.The studies involved 232 tooth agenesis pa-tients with PAX9 variants.Results A novel PAX9 c.447delG(p.Pro150Argfs*62)and a reported PAX9 c.406C>T(p.Gln136*)were identified in two Chinese families.Through bioinformatics analysis and three-dimensional structural mod-eling,we postulated that the frameshift variant was pathogenic.The outcome was the premature cessation of PAX9 pro-tein,which caused severe structural and functional deficiencies.Summarizing the PAX9 genotype-phenotype relationship revealed that patients carrying the PAX9 variant commonly led to loss of the second molars.Conclusion We identified the novel PAX9 c.447delG(p.Pro150Argfs*62)in a Chinese family of non-syndromic oligodontia,expanding the known variant spectrum of PAX9.The most susceptible tooth position for PAX9 variants of tooth agenesis was the second mo-lars and the deciduous molars during the deciduous dentition.

Respiratory syncytial virus(RSV)infection is a potential susceptibility factor for recurrent wheezing,which can affect the occurrence and development of asthma through immune damage,airway epithelial barrier damage,airway inflammatory infiltration,airway hyperresponsiveness,and high expression of induced susceptibility genes.Traditional Chinese medicine believes that asthma caused by RSV infection is mostly caused by the imbalance of the body's qi after infection and the retention of evil qi.By combing the mechanism of RSV infection in the occurrence and development of asthma and the research on traditional Chinese medicine intervention in recent years,it is hoped to provide ideas for the future application of combined Chinese and Western medicine to prevent and treat asthma.

Aim To investigate the role of cholesterol in the regulation of lipid raft and the function of platelets.Methods Using in vitro incubation of methyl β-cyclodextrin(MβCD)and in vivo elevation of peripheral blood total cho-lesterol levels to remove and load platelet cholesterol,respectively.Cholera toxin B staining combined with flow cytometry was used to detect platelet lipid raft content,fluorescence antibody staining combined with flow cytometry was used to detect the expression levels of P-selectin and activated integrin α Ⅱ bβ3,annexin Ⅴ labeling combined with flow cytometry was used to detect the level of phospholipid efflux,in vitro experimental system and rat tail bleeding experiment were used to detect platelet aggregation ability.Results The content of lipid raft on B lymphocytes decreased with the removal of cholesterol,while in vitro incubation of MβCD to remove platelet cholesterol significantly increased its lipid raft level(P＜0.05).Consistent with this,in vivo cholesterol loading increased the lipid raft content of B lymphocytes but decreased the lipid raft content of platelets(P＜0.05).The increase in lipid raft after removing cholesterol was not conducive to platelet activation and aggregation function.In vivo cholesterol loading downregulated platelet lipid raft content(P＜0.05),enhanced its ability to respond to low concentration stimulant for activation aggregation and coagulation,and this enhancing effect disappeared after cholesterol removal.Conclusion Platelet cholesterol is a key regulator of platelet lipid raft content and platelet function,which can negatively regulate lipid raft,promote platelet activation,and enhance their coagulation function.
