ObjectiveThis paper aims to explore the action and molecular mechanism of modified Tongluo Tangtai Formula（MTLTT） on myelin damage in diabetic peripheral neuropathy （DPN） based on network pharmacology and in vitro experiments. MethodsThe chemical components of the MTLTT were retrieved from the Traditional Chinese Medicine Systems Pharmacology （TCMSP） database and literature， and the component targets were collected from the SwissTargetPrediction database. The targets of DPN were collected from the GeneCards， OMIM， Disgenet， and GEO databases. Gene ontology （GO） and Kyoto encyclopedia of genes and genomes （KEGG） enrichment analyses were performed using the Metascape database， and a network diagram was constructed using Cytoscape software. The binding actions of core components with glycogen synthase kinase 3 beta （GSK-3β） and β-catenin were analyzed by Autodock Vina. An in vitro DPN model was established by high glucose-induced Schwann cells and dorsal root ganglion cells （SCs/DRGs）. The ultrastructural morphological changes of SCs and DRGs were observed by scanning electron microscope（SEM）， and the expressions of myelin-associated glycoprotein （MAG） and myelin basic protein （MBP） were detected by immunofluorescence staining. The mRNA and protein expression levels of MAG， MBP， myelin protein 0 （P0）， peripheral myelin protein 22 （PMP22）， and Wnt/β-catenin signaling pathway-related protein β-catenin， GSK-3β， Wnt family member 3α （Wnt3α）， and Wnt inhibitory factor-1 （Wif-1） were detected by real-time polymerase chain reaction （Real-time PCR） and Western blot. ResultsNetwork pharmacology analysis revealed that MTLTT components may treat DPN via the Wnt signaling pathway， involving key proteins such as GSK-3β， β-catenin and Wif-1. The molecular docking results indicate that atropine， apigenin， baicalein， isoflavanone， and albiflorin have good binding activity with GSK-3β， and that all 13 core components have stable binding activity with β-catenin. Cell experiments showed that compared with the blank group， SCs and DRGs in the model group exhibited severe morphological and structural abnormalities such as disintegration， shrinkage and axonal rupture， while these abnormal changes were improved after MTLTT intervention. Immunofluorescence results indicated that the fluorescence intensity of MAG and MBP was markedly decreased in the model group relative to the blank group（P<0.01）， while MTLTT treatment obviously upregulated the expression of MAG and MBP compared with the model group （P<0.01）. Real-time PCR and Western blot assays revealed that the expression levels of myelin-related molecules MAG， MBP， P0 and PMP22 were significantly reduced in the model group （P<0.05，P<0.01）， and MTLTT remarkably increased their expression levels （P<0.05）. In the Wnt/β-catenin signaling pathway， the mRNA levels of GSK-3β， Wif-1 and Wnt3α were elevated and β-catenin mRNA expression was declined in the model group （P<0.01）. Meanwhile， the protein expressions of GSK-3β and Wif-1 were upregulated， whereas those of Wnt3α and β-catenin were downregulated （P<0.01）. Compared with the model group， MTLTT at different doses reduced the mRNA and protein levels of GSK-3β and Wif-1 to varying degrees （P<0.05）， and distinctly enhanced the protein expression of Wnt3α and β-catenin（P<0.01）. ConclusionMTLTT can alleviate high glucose-induced myelin damage. Its protective mechanism may promote myelin repair by upregulating the expression of MAG， MBP， P0 and PMP22， and the therapeutic effect is possibly associated with the activation of Wnt/β-catenin signaling pathway.

Objective To explore the imaging manifestations of Rosai-Dorfman disease(RDD)in children.Methods A total of 12 children with RDD confirmed by pathology were retrospectively enrolled,including 8 cases underwent non-contrast CT(NCCT)+contrast enhanced CT(CECT),2 cases underwent NCCT+CECT+non-contrast MR(NCMR)+contrast enhanced MR(CEMR),1 case underwent NCCT+NCMR and CEMR,while 1 case underwent NCCT and X-ray examinations.Imaging manifestations of RDD in children were observed.Results Among 12 cases,intranodal type RDD was found in 7 case,extranodal type RDD in 3 cases,and mixed type(with both lymph nodes and extranodal sites affected)RDD were noticed in 2 cases.In 7 cases of intranodal type RDD,NCCT and CECT showed multiple lymph node enlargements in both sides of the neck,with uniform isodensity on NCCT and mild-moderate progressive enhancement in 5 cases,while with low-density necrotic area and ring-shaped enhancement in 2 cases.Among 3 cases of extranodal RDD,the lesion in 1 case involved nasal cavity and posterior group of ethmoid sinuses on CT and MRI,which developed circular soft tissue mass centered on nasal septum with moderate heterogeneous enhancement,also compressed the adjacent bone with destruction.In another case of extranodal RDD,CT showed that the lesion involved left ilium and bilateral parietal bones,with bone destruction accompanied by obvious periosteal reaction and soft tissue mass,which was mildly enhanced.In the rest 1 case of extranodal RDD,CT and X-ray film showed that the lesion involved the upper segment of right femur and left parietal bone,with osteolytic destruction accompanied by layered periosteal reaction.The lesions in both 2 cases of mixed type RDD involved brain(1 case involved left parieto-occipital lobe,1 case involved bilateral temporal lobes,left frontal lobe and bilateral occipital lobes),presented as isodensity on CT and equal or slightly low signal intensity on T 1WI,equal-high mixed signal intensity on T2WI,some shaped like brain gyral with mild edema of surrounding tissue,and nodular or mass-like significant enhancement.RDD involvements of bilateral lung,mediastinum and hilar lymph nodes were also observed in the above 2 cases,chest CT showed multiple nodular or small patchy uniform high-density shadows in bilateral lungs,as well as enlarged mediastinum and hilar lymph nodes.Conclusion Imaging manifestations of pediatric RDD had certain specificity,being helpful to diagnosis.

Getah virus(GETV)is an arbovirus capable of infecting humans and vertebrates such as horses and pigs via blood-sucking mosquitoes,which is extremely harmful to the livestock indus-try.Current monitoring methods are time-consuming,costly,and dependent on specialized instru-ments.These characteristics hinder rapid detection in clinical samples.Therefore,the development of a simple,rapid,specific,and sensitive method for detecting GETV antigen is crucial for the pre-vention and control of GETV.In this study,a GETV E1 monoclonal antibody strain SD17/09-E1-mAb was prepared by a prokaryotic expression system for GETV E1 protein expression,and a col-loidal gold double-antibody sandwich assay encapsulating two strains of GETV E1 monoclonal an-tibody wasestablished.The results showed that the prepared colloidal gold test strips had good sen-sitivity and did not cross-react with other common porcine virus-positive tissue samples;the test strips had a high compliance rate with the IFA assay for GETV,and could be stored at 37 ℃ for one month and at room temperature for at least three months.In this study,a colloidal gold anti-surveillance test strip for rapid detection of GETV was successfully prepared,which provides a powerful tool for GETV detection.

Objective To analyze the factors influencing the occurrence of post-embolization syndrome(PES)after transhepatic arterial chemoembolization(TACE).Methods A total of 107 patients with hepatocellular carcinoma(HCC),who received TACE treatment at authors'hospital between February 2021 and March 2023,were included in the study.Among them,56 patients developed PES(PES group)and 51 patients did not develop PES(non-PES group).The demographic data,medical history,pathological findings,laboratory indicators and operation-related materials were compared between the two groups,and the risk factors for PES were analyzed.Results There were statistically significant differences in tumor diameter,albumin(ALB)level,preoperative physical condition(ECOG)score,type of embolization agent,drug-loaded microspheres,number of microspheres,and dosage of loaded drug between the two groups(all P＜0.05).Multivariate Logistic analysis revealed that drug-loaded microspheres,number of microspheres,and dosage of loaded drug were the independent risk factors for PES occurring after TACE(all P＜0.05).Conclusion HCC patients treated with TACE using drug-loaded microspheres,large amount of microspheres and high dosage of loaded drug have a higher risk of PES occurring after TACE.For patients having the above risk factors,the formulation of corresponding perioperative intervention strategies is necessary so as to avoid the occurrence of PES and to improve the safety of TACE.

Objective To observe the efficacy of percutaneous mechanical thrombectomy(PMT)for treating different traditional Chinese medicine(TCM)syndrome type lower extremity arterial thromboses.Methods Forty patients with lower extremity arterial thromboses who underwent PMT were retrospectively enrolled and divided into dampness-heat syndrome group(n=18)and blood stasis syndrome group(n=22)according to TCM syndrome types.The technical success rate,ankle-brachial index(ABI),Rutherford grade and vascular patency rate 12 months after PMT were compared between groups.Perioperative complications and adverse events during follow-up were recorded.Results The technical success rate of PMT in dampness-heat syndrome group and blood stasis syndrome group was 94.44%(17/18)and 100%(22/22),respectively.Twelve months after PMT,ABI was 0.45±0.11 and 0.52±0.14,and vascular patency rate was 94.44%(17/18)and 81.82%(18/22)in dampness-heat syndrome group and blood stasis syndrome group,respectively,both not significantly different between groups(all P＞0.05).No significant difference of Rutherford grade before treatment was found between groups(P＞0.05),while 12 months after PMT,Rutherford grade in dampness-heat syndrome group was higher than in blood stasis syndrome group(P＜0.05).During perioperative period,false aneurysm of brachial artery occurred in 1 case in dampness-heat syndrome group,while osteofascial compartment syndrome and atrial fibrillation occurred each in 1 case in blood stasis syndrome group,both relieved after treatments.No serious adverse event such as amputation nor death occurred during follow-up.Conclusion PMT was effective and safe for treating different TCM syndrome type lower extremity arterial thromboses.The prognosis of patients with blood stasis syndrome type lower extremity arterial thromboses was better than that of those with dampness-heat syndrome.

Objective To assess the impact of statins combined with sorafenib(SRF)therapy on survival outcomes in patients with metastatic renal cell carcinoma(mRCC).Methods Clinical data of mRCC patients treated in the 908th Hospital of the Joint Security Force from November 2019 to November 2023 were retrospectively analyzed.They were categorized into statin group and non-statin group according to whether they used statins or not,and the differences in the primary endpoint of overall survival(OS),secondary endpoints of progression-free survival(PFS),objective response rate(ORR),and disease control rate(DCR)were compared between the two groups.Results A total of 80 patients were included in the study,with 27 in the statin group and 53 in the non-statin group.There were no statistically significant differences in partial remission,stable disease,disease progression,and DCR between the two groups(P＞0.05);complete remission and ORR were significantly higher in the statin group than in the non-statin group(P＜0.05).Kaplan-Meier analysis showed that,compared with the non-statin group,the median PFS and OS of the statin group were prolonged,and the difference in median PFS between the two groups was statistically significant(P＜0.05).In terms of safety,the incidence of other adverse events was similar in both groups(P＞0.05).Conclusion Statins combined with SRF treatment regimen can improve ORR and DCR and prolong median PFS and OS in patients with mRCC.
