Diabetic nephropathy （DN） is one of the most common and severe microvascular complications of diabetes， with a complex pathogenesis involving immune inflammatory responses， oxidative stress， apoptosis， glomerulosclerosis， renal interstitial fibrosis， and other pathological processes. In recent years， numerous animal or cell model experiments have revealed that the transforming growth factor-β （TGF-β）/mothers against decapentaplegic homolog （Smad）， phosphoinositide 3-kinase （PI3K）/ protein kinase B （Akt）/mammalian target of rapamycin （mTOR）， mitogen-activated protein kinase （MAPK）， AMP-activated protein kinase （AMPK）， nuclear factor-κB （NF-κB）， Janus kinase （JAK）/signal transducer and activator of transcription （STAT）， neurogenic locus notch homolog protein （Notch）， nuclear factor E₂-related factor 2 （Nrf2）， secretory glycoprotein （Wnt）/β-catenin， and other classical signaling pathways play important roles in the occurrence and development of DN. Traditional Chinese medicines， as natural drugs， possess characteristics such as multiple components， multiple targets， and few adverse reactions， demonstrating unique advantages in regulating the aforementioned signaling pathways and improving renal pathological changes. This review summarized recent research progress on the intervention of DN through the regulation of the aforementioned signaling pathways by single compounds and formulas of traditional Chinese medicine， focusing on their mechanisms of action in regulating immune inflammatory responses， inhibiting renal fibrosis， oxidative stress， improving metabolic disorders， and other aspects. The aim is to provide theoretical references for a deeper understanding of the modern pharmacological basis and clinical application of traditional Chinese medicine in the treatment of DN.

Objective:To analyze the efficacy of enzyme replacement therapy and anti-drug antibody production in children with Fabry disease.Methods:The clinical data of 7 children with Fabry disease treated with enzyme replacement therapy for more than 1 year at Children′s Hospital of Zhejiang University School of Medicine from July 2021 to June 2024 were retrospectively analyzed. The basic information and the changes of related clinical indicators before and after treatment were collected. Paired sample t test was used to compare renal function, left heart mass index, pain score and other related indexes before and after treatment. The anti-drug antibodies were detected by enzyme-linked immunosorbent assay. Results:A total of 6 boys and 1 girl were included. The age of diagnosis was (12.2±1.8) years. After 1 year of enzyme replacement therapy, the abnormal substrate globotriaosylsphingosine and brief pain inventory scores of all children were significantly lower than those before treatment ((16±11) vs. (63±42) μg/L, 22±19 vs. 45±29, t=3.88, 3.43, both P<0.05). There were no significant differences in glomerular filtration rate, urinary microalbumin to creatinine and left heart mass index before and after treatment ((124±35) vs. (136±26) ml/(min·1.73 m 2), (9.3±8.3) vs. (3.8±2.5) mg/g, (38±9) vs. (33±6) g/m 2.7, t=1.33, 1.74, 1.19, all P>0.05). Patients 4, 5 and 6 developed anti-drug antibodies at 1 month, 4 months and 1 month after medication, respectively. Patient 4 had persistently high anti-drug antibody titers (absorbance 3.65-3.73) accompanied by urticaria, elevated globotriaosylsphingosine and worsening clinical symptoms. Conclusions:The enzyme replacement therapy can effectively improve the clinical symptoms and reduce the level of globotriaosylsphingosine in children with Fabry disease. The anti-drug antibody is common in patients after long-term enzyme replacement therapy and may diminish the efficacy, which needs dynamic monitoring.

Objective To investigate the effect and mechanism of lentivirus-mediated overexpression of suppressors of cytokine sig-naling 3(SOCS3)on the heart of rats with experimental autoimmune myocarditis(EAM).Methods Thirty Lewis rats were randomly di-vided into a control group,EAM group and EAM+SOCS3 group.The EAM rat model was established by subcutaneous injection of cardiac myosin.On day 0 of the experiment,the EAM+SOCS3 group was injected with lentivirus overexpressing SOCS3 via the tail vein,and the EAM group was injected with an equal amount of empty vector lentivirus.On day 21 of the experiment,all rats underwent echocardio-graphy to evaluate cardiac function and were then euthanized.Hematoxylin-eosin(HE)staining was used to observe the pathological changes of myocardial tissue.Enzyme-linked immunosorbent assay(ELISA)was used to detect the levels of serum cardiac troponin T,creatine kinase-myocardial band,B-type natriuretic peptide,and myocardial interleukin-6,interleukin-1 β and tumor necrosis fac-tor-α.Immunohistochemistry,real-time quantitative PCR(RT-qPCR)and Western blot(WB)were used to detect the expressions of SOCS3,Janus kinase 2(JAK2),signal transducer and activator of transcription 3(STAT3),monocyte chemoattractant protein-1(MCP-1),and transforming growth factor-β(TGF-β)in myocardial tissue.Results The myocardial pathological score,serum lev-els of cardiac troponin T,creatine kinase-myocardial band,B-type natriuretic peptide,and myocardial levels of interleukin-6,inter-leukin-1β,and tumor necrosis factor-α in the EAM group were significantly higher than those in the control group(P＜0.05).The cardiac function of the EAM group was significantly lower than that of the control group(P＜0.05).The mRNA and protein expressions of myocardial JAK2,STAT3,MCP-1 and TGF-β in the EAM group were significantly higher than those in the control group(P＜0.05).These indexes in the EAM+SOCS3 group were significantly restored compared with those in the EAM group(P＜0.05).The mRNA and protein expressions of SOCS3 in the myocardial tissue of the EAM+SOCS3 group were significantly higher than those in the EAM group(P＜0.05).Conclusion Overexpression of SOCS3 may ameliorates the inflammatory response of the myocardium in EAM rats and im-prove cardiac function by inhibiting the JAK2/STAT3 signaling pathway and downregulating the expressions of MCP-1 and TGF-β.

Objective:To investigate the effect of repetitive transcranial magnetic stimulation(rTMS)on sleep structure and quality in children with autism spectrum disorder(ASD).Methods:Sixty children with ASD who met the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)criteria were randomly assigned to rTMS treatment group and pseudo-treatment group.The rTMS group received bilateral low-frequency(0.5 Hz)stimulation,and the pseudo-treatment group received pseudo-stimulation at the same time and place.Sleep quality and autism symptoms were assessed at baseline,midpoint(15 sessions),and endpoint(30 sessions),using the Childhood Sleep Disorders Scale(SDSC)and the Behavior Rating Scale for Children with Autism Spectrum Disorders(ABC)before treatment,15 times and 30 times of intervention,and statistical analysis was performed.Results:There was no significant difference in SDSC factor and total score between the two groups before treatment(P＞0.05).After 15 and 30 treatments,the total scores of SDSC and all factors were lower in the rTMS group than in the pseudo-treatment group(P＜0.05).Repeated measurement ANOVA found that there was an interaction be-tween the groups and the number of interventions,that is,the scores of the two groups had different downward trends,and the decline of the treatment group was more obvious than that of the pseudo-treatment group.There was no significant difference in the interaction between ABC scale scores and intervention times(P＞0.05).Conclu-sion:Repetitive transcranial magnetic stimulation significantly improves the sleep structure and quality in children with autism spectrum disorder.

ObjectiveTo investigate the effect and underlying mechanism of the Wulao Qisun prescription on pathological new bone formation in ankylosing spondylitis （AS）. MethodsSynovial fibroblasts were isolated from the hip joints of AS patients and observed under a microscope to assess cell morphology. The cells were identified using immunofluorescence staining. The isolated AS fibroblasts were divided into blank group， low drug-containing serum group， medium drug-containing serum group， high drug-containing serum group， and positive drug group. After drug intervention， cell proliferation was measured using the cell counting kit-8 （CCK-8） assay to observe fibroblast growth and determine the optimal intervention time. Alkaline phosphatase （ALP） activity was measured using the alkaline phosphatase assay. Protein expression of osteocalcin （OCN）， osteopontin （OPN）， and runt-related transcription factor 2 （Runx2） was detected by Western blot. The mRNA expression levels of Wnt5a， β-catenin， and Dickkopf-1 （DKK-1） were measured by real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsCompared with the blank group， each drug-containing serum group of Wulao Qisun prescription and the positive drug group inhibited the proliferation of AS fibroblasts and reduced ALP expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription downregulated β-catenin mRNA expression （P<0.05）. The medium and high drug-containing serum groups and the positive drug group significantly downregulated Wnt5a and β-catenin mRNA expression （P<0.05， P<0.01）， with the positive drug group showing the most pronounced effect （P<0.01）. The high drug-containing serum group and the positive drug group significantly upregulated DKK-1 mRNA expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription inhibited the expression of OPN and Runx2 proteins （P<0.05， P<0.01）， while the medium and high drug-containing serum groups and the positive drug group inhibited the expression of OCN， OPN， and Runx2 proteins （P<0.05， P<0.01）. ConclusionThe Wulao Qisun prescription can inhibit the proliferation and osteogenic differentiation of AS fibroblasts， thereby delaying the formation of pathological new bone in AS. The possible mechanism involves the regulation of Wnt/β-catenin-related gene expression， further inhibiting the transcription of downstream target genes.
