This paper reports a case of hepatoblastoma that is inclined to misdiagnosis and missed diagnosis. The patient, a 6-month-old male, was admitted to Dermatology Department of Children’s Hospital of Nanjing Medical University and Beijing Children’s Hospital successively, because of a erythema on the neck for 6 months and a mass in the neck for 3 months. Abdominal ultrasonography and CT indicated the possibility of hepatic hemangioma, but further examination of alpha fetoprote and other indicators suggested hepatic malignant tumor. Therefore, surgery was performed to remove the liver mass, and postoperative pathology revealed hepatoblastoma. Postoperative chemotherapy was combined, and follow-up was conducted six months after the end of chemotherapy, with no recurrence of the disease. This article summarized the diagnosis and treatment process of this case and combined with literature review to provide experience for clinicians in the diagnosis and treatment of relevant cases.

BACKGROUND:Psoralen has a strong anti-osteoporotic activity and may have a restorative effect on chemotherapy-induced osteoporosis. OBJECTIVE:To explore the restorative effect of psoralen on the osteogenic differentiation of bone marrow mesenchymal stem cells in mice inhibited by cyclophosphamide and its mechanism. METHODS:C57BL/6 mouse bone marrow mesenchymal stem cells were isolated and cultured.Effect of psoralen on viability of bone marrow mesenchymal stem cells was detected by MTT assay.Osteogenic induction combined with alkaline phosphatase staining was used to determine the optimal dose of psoralen to restore the osteogenic differentiation of bone marrow mesenchymal stem cells inhibited by cyclophosphamide.The mRNA expression levels of Runx2,alkaline phosphatase,Osteocalcin,osteoprotegerin,and Wnt/β-catenin signaling pathway-related genes Wnt1,Wnt4,Wnt10b,β-catenin,and c-MYC were measured by RT-qPCR at different time points under the intervention with psoralen.The protein expression of osteogenic specific transcription factor Runx2 and Wnt/β-catenin signaling pathway related genes Active β-catenin,DKK1,c-MYC,and Cyclin D1 was determined by western blot assay at different time points under the intervention with psoralen. RESULTS AND CONCLUSION:(1)There was no significant effect of different concentrations of psoralen on the viability of bone marrow mesenchymal stem cells.The best recovery of the inhibition of osteogenic differentiation of bone marrow mesenchymal stem cells caused by cyclophosphamide was under the intervention of psoralen at a concentration of 200 μmol/L.(2)Psoralen reversed the reduction in osteogenic differentiation marker genes Runx2,alkaline phosphatase,Osteocalcin and osteoprotegerin mRNA expression and Runx2 protein expression in bone marrow mesenchymal stem cells caused by cyclophosphamide conditioned medium.(3)Psoralen reversed the decrease in Wnt/β-catenin pathway-related genes Wnt4,β-catenin,c-MYC mRNA and Active β-catenin,c-MYC,and Cyclin D1 protein expression and the increase in DKK1 protein expression in bone marrow mesenchymal stem cells caused by cyclophosphamide conditioned medium.(4)The results showed that cyclophosphamide inhibited osteogenic differentiation of bone marrow mesenchymal stem cells in mice,and psoralen had a restorative effect on it.The best intervention effect was achieved at a concentration of 200 μmol/L psoralen,and this protective effect might be related to the activation of Wnt4/β-catenin signaling pathway by psoralen.

Psychological factors have become significant contributors to the onset and progression of insomnia. This article explored the treatment of insomnia from the perspective of “liver governs wei qi （defensive qi）”. The concept of “liver governs wei qi （defensive qi）” is summarized in three aspects， firstly， the liver assists the spleen and stomach in transformation and transportation， governing the generation of wei qi； secondly， the liver aids lung qi diffusion and dispersion， governing the distribution of wei qi； thirdly， the liver regulates circadian rhythms， governing the circulation of wei qi. It is proposed that the clinical treatment of insomnia should focus on the following methods： for regulating the liver to harmonize the five viscera， and facilitate the circulation of wei qi， medicinals entering the liver channel include Chaihu （Bupleuri radix）， Baishao （Paeoniae Radix Alba）， Zhizi （Gardeniae Fructus）， and Suanzaoren （Ziziphi Spinosae Semen） could be commonly used； for nourishing the liver， the treatment should align with the day-night rhythm， and herbs such as Baihe （Lilium）， Hehuan （Albizia julibrissin）， and Yejiaoteng （Polygoni multiflori caulis） are commonly used； for soothing the liver and address both mental and physical health to calm wei qi， treatment should advocate verbal counseling， psychological regulation， and health education. Ultimately， this treatment approach can free liver qi to flow， soothe qi movement， restore the motion of wei qi， regulate during day and night， balance yin and yang， and resolve insomnia effectively.

ObjectiveBased on ultra-high performance liquid chromatography-quadrupole-electrostatic field orbital trap-linear ion-trap mass spectrometry（UPLC-Orbitrap Fusion Lumos Tribrid-MS）， the plasma concentration of ziyuglycoside Ⅰ was determined at different time points after oral administration， and its pharmacokinetic characteristics in normal rats and rats with acute kidney injury were compared. MethodsRats were randomly divided into normal group and model group， the model group received intraperitoneal cisplatin（10 mg·kg^-1） to establish the acute kidney injury model， the normal group was given the same volume of saline. After successful modeling， rats in the normal and model groups were randomly divided into the normal low， medium and high dose groups（2.5， 5， 7.5 mg·kg^-1） and the model low， medium and high dose groups（2.5， 5， 7.5 mg·kg^-1）， 6 rats in each group， and the plasma was collected at different time points after receiving the corresponding dose of ziyuglycoside Ⅰ. Then， the concentration of ziyuglycoside Ⅰ in rat plasma was determined by UPLC-Orbitrap Fusion Lumos Tribrid-MS， and the drug-time curve was poltted. The pharmacokinetic parameters were calculated by Kinetica 5.1 software， and the differences in pharmacokinetic parameters between different administration groups were compared by independent sample t-test with SPSS 22.0. ResultsThe pharmacokinetic results showed that after receiving the different doses of ziyuglycoside Ⅰ， its concentration increased first and then decreased， and all of them reached the maximum plasma concentration at about 0.5 h. The area under the curve（AUC_0-t） and mean retention time（MRT_0-t） of normal and model rats increased with the increased dose， and the clearance（CL） decreased with the increasing dose. Compared with the normal group， the AUC_0-t was significantly increased（P<0.01）， peak concentration（C_max） and CL decreased in model rats at different doses， indicating that the physiological state of the rats could affect the absorption and elimination of ziyuglycoside Ⅰ in vivo. ConclusionThe pharmacokinetic characteristics of ziyuglycoside Ⅰ are quite different in normal rats and acute kidney injury model rats， which may be due to the change of the body environment in the pathological state， then lead to changes in absorption and metabolic processes.

The operation time, intraoperative blood loss, incision length, hospitalization time, time to return to work, exercise and VAS scores in the group B and group C were lower than those in the group A: (49.32 ± 4.74), (48.12 ± 4.68) min vs. (66.71 ± 5.84) min; (15.32 ± 1.01), (15.62 ± 0.79) ml vs.(19.86 ± 1.20) ml; (7.69 ± 0.57), (3.76 ± 0.50) cm vs. (8.98 ± 0.62) cm; (7.01 ± 0.91), (6.82 ± 0.83) d vs.(8.74 ± 1.12) d; (56.32 ± 8.01), (55.17 ± 7.84) d vs. (63.17 ± 6.68) d; (6.13 ± 1.20), (5.94 ± 1.04) months vs. (8.21 ± 1.20) months; (2.76 ± 0.50), (2.55 ± 0.76) scores vs. (3.98 ± 0.62) scores, there were statistical differences ( P<0.05). At 1, 6 and 12 months after surgery, the American Society for Foot and Ankle Surgery (AOFAS) scores in the three groups were significantly increased, and the AOFAS scores in the group B and group C were higher than those in the group A, there were statistical differences ( P<0.05). The total incidence of complications in the group C was lower than that in the group A: 2/20 vs. 8/20, there was statistical difference ( χ2 = 4.80, P<0.05). The total incidence of complications in the group B and group C had no statistical difference ( P>0.05). Conclusions:Modified Kessler method and minimally invasive suture with threaded rivets have the advantages of high efficiency and safety in the treatment of acute closed Achilles tendon rupture, and their efficacy is higher than that of traditional open suture.

YTHDF2 is a key m6A RNA modification"reader"that plays a crucial role in cell biological processes and tumor development.This review deeply explores the biological role of YTHDF2 and the advances in its application in tumors.The YTHDF2 structures are divided into mRNA procsomes and YTH domains,which recognize and bind m6A modified RNA molecules.It plays a biological role by promoting mRNA degradation,regu-lating cell signaling pathways and metabolism,and can regulate macrophage function and maintain an immunosup-pressive state in the tumor microenvironment.YTHDF2 has the potential to serve as diagnostic markers,therapeu-tic targets and prognostic evaluation biomarkers in different tumors,but currently relevant studies are insufficient in sample size,molecular mechanism and clinical application.In the future,research can be conducted on compre-hensive clinical research,in-depth analysis of molecular mechanisms,and research and development of optimized treatment strategies.

Objective:To investigate the expression and clinical value of integrin-associated protein 47 (CD47) and soluble programmed death receptor-ligand 1 (sPD-L1) in patients with primary immune thrombocytopenia (ITP).Methods:The method of retrospective study was adopted, 76 patients with ITP admitted to the Affiliated Hospital of Jining Medical University from July 2016 to July 2022 were regarded as the study group, and another 76 cases of physical examination were regarded as the control group. The levels of serum CD47, sPD-L1, interleukin-33(IL-33) and transforming growth factor beta (TGF-β) were determined by the enzyme-linked immunosorbent assay, the diagnostic value of CD47 and sPD-L1 for ITP was analyzed by the receiver operating characteristic (ROC) curve, Pearson test was applied to analyze the correlation between serum CD47 and sPD-L1 in ITP patients, multivariate Logistic regression analysis was applied to analyze the risk factors affecting ITP.Results:The levels of serum CD47, sPD-L1 and IL-33 in the study group were higher than those in the control group: (40.31 ± 6.59) μg/L vs. (32.16 ± 6.33) μg/L, (78.42 ± 10.22) ng/L vs. (64.49 ± 10.36) ng/L, (73.29 ± 14.26) ng/L vs. (26.54 ± 5.16) ng/L; the level of serum TGF-β in the study group was lower than that in the control group: (1 752.66 ± 310.73) ng/L vs. (2 625.88 ± 389.58) ng/L, there were statistical differences ( P<0.05). The result of the Pearson test showed that there was a positive correlation between serum CD47 and sPD-L1 in ITP patients ( r = 0.572, P<0.05). The result of the ROC curve showed that the area under the curve predicted by the combination of serum CD47 and sPD-L1 was 0.948 (95% CI 0.916 - 0.979), which was better than that predicted by CD47 and sPD-L1 alone ( P<0.05). The result of multivariate Logistic regression analysis showed that CD47, sPD-L1, and IL-33 were the risk factors affecting ITP ( P<0.05), and TGF-β was the protective factor affecting ITP ( P<0.05). Conclusions:The serum levels of CD47 and sPD-L1 in patients with ITP are elevated, and the combined detection of the two indicators has a good diagnostic value for ITP.

Objective·To investigate the therapeutic effects of neferine(Nef)on intervertebral disc degeneration(IDD)and the underlying regulatory pathways.Methods·The effects of Nef on the viability and proliferation of nucleus pulposus cells were assessed using the cell counting kit-8(CCK-8)assay.Molecular docking software was employed to analyze the potential binding sites of Nef within the Kelch domain of kelch-like ECH-associated protein 1(KEAP1).Tumor necrosis factor-α(TNF-α)was used to induce ferroptosis and inflammation in nucleus pulposus cells.Western blotting was performed to detect the expression levels of nuclear factor erythroid 2-related factor 2/glutathione peroxidase 4(NRF2/GPX4)pathway-and nuclear factor-KB(NF-κB)pathway-related proteins under TNF-α stimulation with or without Nef.The effect of Nef on the metabolism of extracellular matrix in nucleus pulposus cells was evaluated using high-density cell culture.A needle puncture-induced IDD rat model was established,and 5 μL of 1.5 μmol/L Nef was injected twice into the intervertebral disc at the Co3/4 level(IDD+Nef group),while an equivalent volume of PBS was injected into the Co2/3 disc(IDD group).After 4 weeks,the intervertebral space height was detected by X-ray,disc degeneration was detected by magnetic resonance imaging,and disc structure was evaluated by histological staining.Results·The CCK-8 assay revealed that Nef at concentrations of 1.5 μmol/L and below did not inhibit the viability and proliferation of nucleus pulposus cells.Molecular docking results suggested that Nef might activate NRF2 by directly binding to the KEAP1 Kelch domain,thereby reducing the interaction between KEAP1 and NRF2.Western blotting indicated that Nef significantly increased the expression of the key ferroptosis-inhibiting proteins NRF2 and GPX4,while decreasing the expression of the phospho-P65 protein in the NF-κB pathway(all P＜0.05).The high-density culture of nucleus pulposus cells demonstrated that Nef mitigated the TNF-α-induced degradation of the extracellular matrix(P＜0.05).Animal study results showed that compared to the IDD group,the IDD+Nef group exhibited a greater intervertebral disc space height,a lower Pfirrmann grade(both P＜0.05),and a reduced degree of histological degeneration.Conclusion·Nef may inhibit TNF-α-induced ferroptosis in nucleus pulposus cells by activating the KEAP1/NRF2/GPX4 pathway and reduce TNF-α-induced inflammation and extracellular matrix degradation by suppressing the NF-κB pathway,thereby alleviating IDD in rats.
