OBJECTIVE: Circadian rhythm disruption (CRD) is a risk factor that correlates with poor prognosis across multiple tumor types, including hepatocellular carcinoma (HCC). However, its mechanism remains unclear. This study aimed to define HCC subtypes based on CRD and explore their individual heterogeneity. METHODS: To quantify CRD, the HCC CRD score (HCCcrds) was developed. Using machine learning algorithms, we identified CRD module genes and defined CRD-related HCC subtypes in The Cancer Genome Atlas liver HCC cohort (n = 369), and the robustness of this method was validated. Furthermore, we used bioinformatics tools to investigate the cellular heterogeneity across these CRD subtypes. RESULTS: We defined three distinct HCC subtypes that exhibit significant heterogeneity in prognosis. The CRD-related subtype with high HCCcrds was significantly correlated with worse prognosis, higher pathological grade, and advanced clinical stages, while the CRD-related subtype with low HCCcrds had better clinical outcomes. We also identified novel biomarkers for each subtype, such as nicotinamide n-methyltransferase and myristoylated alanine-rich protein kinase C substrate-like 1. CONCLUSION We classify the HCC patients into three distinct groups based on circadian rhythm and identify their specific biomarkers. Within these groups greater HCCcrds was associated with worse prognosis. This approach has the potential to improve prediction of an individual's prognosis, guide precision treatments, and assist clinical decision making for HCC patients.

Treatment primarily focused on symptomatic and supportive care. Through the multidisciplinary rare disease consultation, holistic support was provided to the patient, offering comprehensive care from various specialtiesx.We also aim to use this case report to enhance clinicians′ under-standing of SIOD and improve the management and treatment of rare diseases.

Objective:To investigate the expression and clinical significance of CD30 in patients with diffuse large B-cell lymphoma(DLBCL).Methods:A retrospective analysis was conducted on 124 cases of primary DLBCL diagnosed at Changzhou Second People's Hospital Affiliated with Nanjing Medical University from January 2018 to July 2020.The expression of CD30 in patients with DLBCL was detected by immunohistochemical method,and the clinicopathological characteristics were analyzed and compared between CD30+and CD30-groups.Kaplan-Meier analysis was used for survival analysis.The relationship between CD30 expression and clinical features and prognosis were analyzed.Results:Among the 124 patients with DLBCL,19 patients expressed CD30,and the positive rate is 15.32％.The clinico-pathological characteristics of CD30+in patients with DLBCL were characterized by low age,more common in males,fewer extranodal lesions,lower international prognostic index(IPI),GCB type being more common in Hans subtype,and achieving better therapeutic effects(P＜0.05).However,there were no significant statistical differences in B-symptoms(P=0.323),Ann Arbor staging(P=0.197),Eastern Cooperative Oncology Group(ECOG)score(P=0.479),lactate dehydrogenase(LDH)(P=0.477),and the involvement of bone marrow(P=0.222).There were significant differences in OS and PFS between the CD30+and CD30-groups(x2=5.653,P=0.017;x2=4.109,P=0.043),the CD30+group had a better prognosis than that of the CD30-group.The results of subgroup analysis showed that the CD30+group in the IPI score=1-2,LDH elevated group had a better prognosis(P＜0.05).In the subgroups of Ann Arbor staging Ⅲ-Ⅳ(P=0.055)and non GCB type(P=0.053),the CD30+group had a good prognosis trend,but the difference was not statistically significant.The results of univariate analysis showed that the good prognosis of DLBCL patients was closely related to CD30+expression,no B-symptoms,early Ann Arbor staging,low ECOG score,normal LDH,low IPI score,fewer extranodal involvement,and obtaining the best therapeutic effect as CR(all P＜0.05).COX multivariate regression analysis showed that the presence of B-symptoms and achieving the best therapeutic effect as Non-CR were independent risk factors affecting the prognosis of DLBCL patients(P＜0.05).Conclusion:The CD30+expression in DLBCL patients indicates a good prognosis and has certain diagnostic value in evaluating the prognosis of DLBCL patients.

Objective:RS4;11 cell line was used to establish BCL-2 inhibitor-resistant cell lines of B-cell acute lymphoblastic leukemia(B-ALL)and explore the possible mechanisms of drug resistance.Methods:RS4;11 cell line was continuously induced and cultured by low and ascending concentrations of BCL-2 inhibitors navitoclax and venetoclax to construct navitoclax-resistant cell line RS4;11/Nav and venetoclax-resistant cell line RS4;11/Ven.The cell viability was detected by MTT assay,and the cell apoptosis was detected by flow cytometry.Differentially expressed genes(DEGs)between RS4;11 drug-resistant cell lines and parental cell line were detected by transcriptome sequencing technology(RNA-seq),and mRNA expression levels of DEGs between drug-resistant cell lines and parental cell line were detected by real-time PCR(RT-PCR).Western blot was used to detect the expression levels of BCL-2 family anti-apoptotic proteins in drug-resistant cell lines and parental cell line.Results:The drug-resistant cell lines RS4;11/Nav and RS4;11/Ven were successfully established.The resistance index(RI)of RS4;11/Nav to navitoclax and RS4;11/Ven to venetoclax was 328.655±47.377 and 2 894.027±300.311,respectively.The results of cell apoptosis detection showed that compared with the drug-resistant cell lines,RS4;11 parental cell line were significantly inhibited by BCL-2 inhibitors,while the apoptosis rate of drug-resistant cell lines was not affected by the drugs.Western blot assay showed that the expression of anti-apoptotic proteins of BCL-2 family did not increase significantly in drug-resistant cell lines.RNA-seq,RT-PCR and Western blot assays showed that the expression of EP300 in drug-resistant cell lines was significantly higher than that in parental cell line(P＜0.05).Conclusion:Drug-resistant B-ALL cell lines could be successfully established by exposing RS4;11 cell line to the ascending concentration of BCL-2 inhibitors,and the drug resistance mechanism may be related to the overexpression of EP300.

Objective To systematically evaluate the clinical efficacy and safety of therapy of tonifying kidney and promoting blood circulation(shortened as Bushen Huoxue method)combined with cyclosporine plus androgen for the treatment of aplastic anemia(AA).Methods Randomized controlled trials(RCTs)of Bushen Huoxue method combined with cyclosporine plus androgen(trial group)versus cyclosporine plus androgen alone(control group)for the treatment of AA were retrieved from the major domestic and oversea databases,and then high-quality RCTs that met the inclusion criteria were screened.RevMan 5.3 software was used for meta-analysis.Results A total of 6 RCTs involving 365 patients were included.The results of meta-analysis showed that the total effective rate of AA in the trial group was significantly superior to that of the control group[OR=4.43,95%CI(2.50,7.84);P＜0.000 01].The trial group was superior to the control group on improving the peripheral blood indicators such as hemoglobin(HGB)level[MD=14.85,95%CI(10.66,19.05);P＜0.000 01],white blood cell(WBC)level[MD=0.61,95%CI(0.21,1.01);P=0.003],platelet(PLT)level[MD=16.51,95%CI(9.28,23.75);P＜0.000 01],and did not increase the incidence of adverse reactions such as hirsutism[OR=0.24,95%CI(0.10,0.61);P=0.003],acne[OR=0.30,95%CI(0.13,0.66);P=0.003],and abnormal liver function[OR=0.28,95%CI(0.09,0.83);P=0.02].Conclusion Bushen Huoxue method combined with cyclosporine plus androgen for the treatment of AA is superior to the use of cyclosporine plus androgen alone on enhancing clinical efficacy and improving the peripheral blood indicators,and has certain advantages in reducing the incidence of adverse reactions.

Objective To analyze the stress changes of thoracic vertebra(T)11-sacrum(S)titanium rods in patients with ankylosing spondylitis after vertebral column decancellation(VCD)osteotomy,and provide reference for the selection and improvement of titanium rods before surgery.Methods The original data of the continuous scanning tomographic images of patients with ankylosing spondylitis after VCD osteotomy were imported into Mimics 21.0 in DICOM format,and T11-S vertebrae,screws and titanium rods were respectively reconstructed.They were imported into 3-Matic to establish a preliminary geometric modeling,and then processed with noise removal,paving,smoothing,etc.The improved model was imported into Hypermesh 10 software for grid division,and the material was imported into ANSYS 19.2 to display the finite element model after attribute assignment,Set the boundary and load conditions,and measure the stress value at the connection between the screw and the titanium rod.Results Under neutral position,forward bending,lateral bending,and axial rotation conditions,the titanium rod had the highest stress at the upper vertebrae(T11)and the lowest stress at the top vertebrae(L3);Under the backward extension condition,the titanium rod has the highest stress at the lower end vertebra(L5).Conclusion In the upper and lower vertebrae,it is possible to consider increasing the diameter of the titanium rod,enhancing its hardness,or changing it to a double rod.

Objective: To explore the value of catheter-based adrenal ablation in treating Cushing's syndrome (CS)-associated hypertension. Methods: A clinical study was conducted in patients with CS, who received catheter-based adrenal ablation between March 2018 and July 2023 in Daping Hospital. Parameters monitored were blood pressure (outpatient and 24-hour ambulatory), body weight, clinical characteristics, serum cortisol and adrenocorticotropic hormone (ACTH) at 8 am, 24-hour urinary free cortisol (24 h UFC), fasting blood glucose and postoperative complications. Procedure effectiveness was defined as blood pressure returning to normal levels (systolic blood pressure<140 mmHg (1 mmHg=0.133 kPa) and diastolic blood pressure<90 mmHg), cortisol and 24 h UFC returning to normal and improvement of clinical characteristics. The parameters were monitored during follow up in the outpatient department at 1, 3, 6, and 12 months after catheter-based adrenal ablation. Results: A total of 12 patients (aged (40.0±13.2) years) were reviewed. There were 5 males, with 5 cases of adenoma and 7 with hyperplasia from imaging studies. Catheter-based adrenal ablation was successful in all without interruption or surgical conversion. No postoperative complication including bleeding, puncture site infection, adrenal artery rupture or adrenal bleeding was observed. The mean follow up was 28 months. Compared to baseline values, body weight declined to (59.48±11.65) kg from (64.81±10.75) kg (P=0.008), fasting blood glucose declined to (4.54±0.83) mmol from (5.53±0.99) mmol (P=0.044), outpatient systolic blood pressure declined to (128±21) mmHg from (140±19) mmHg (P=0.005), diastolic blood pressure declined to (78±10) mmHg from (86±11) mmHg (P=0.041), and the mean ambulatory daytime diastolic blood pressure declined to (79±12) mmHg from (89±8) mmHg (P=0.034). Catheter-based adrenal ablation in 8 patients was defined as effective with their 24 h UFC significantly reduced after the procedure (1 338.41±448.06) mmol/L from (633.66±315.94) mmol/L, P=0.011). The change of 24 h UFC between the effective treatment group and ineffective group was statistically significant (P=0.020). The postoperative systolic blood pressure in the treated adenoma group was significantly lower than those of hyperplasia group (112±13) mmHg vs. (139±20) mmHg, P=0.026). Conclusions: For patients with CS-associated hypertension who are unwilling or unable to undergo surgical treatment, catheter-based adrenal ablation could improve the blood pressure and cortisol level. Catheter-based adrenal ablation could be a safe, effective, and minimally invasive therapy. However, our results still need to be validated in further large-scale studies.
