    Abstract WD repeat- and FYVE domain-containing protein 4 (WDFY4), coded by a gene on 10q11.23, is a member of the BEACH (Beige and Chediak-Higashi) domain-containing family. Genome-wide association studies identified WDFY4 variants as a risk factor for SLE in Asian and European populations. WDFY4 variants are also associated with RA and primary biliary cholangitis, in different ancestry populations. The WDFY4 protein plays an essential role in the cross-presentation of classic dendritic cells, reactive oxygen species-induced apoptosis of CD8+ T cells, and non-canonical autophagic activity in B cells. A novel variant rs7919656 was identified in Japanese clinically amyopathic dermatomyositis patients, with a highly expressed truncated isoform augmenting the melanoma differentiation-associated gene 5 (MDA5) signalling pathway. The same variant was later found to be significantly associated with RP-ILD in Chinese MDA5+DM patients. Here, we briefly review the association of WDFY4 with autoimmune diseases and its known function in immune response.

    Abstract Chimeric antigen receptor T cell (CAR-T) therapy, an innovative immune cell therapy, has revolutionised the treatment landscape of haematological malignancies. The past two years have witnessed the successful application of CD19-targeting CAR constructs in refractory cases of autoimmune rheumatic diseases, including systemic lupus erythematosus, systemic sclerosis, and anti-synthetase syndrome. In comparison to existing B cell depletion therapies, targeting CD19 has demonstrated a more rapid and profound therapeutic effect, enabling drug-free remission with manageable adverse events. These promising results necessitate validation through long-term, large-sample, randomized controlled studies. Corroborating the role of CAR-T therapy in refractory rheumatological disorders and affirming safety, efficacy and durability of responses are the aims of future clinical studies. Optimising the engineering strategies and better patient selection are also critical to further refining the successful clinical implementation of CAR-T therapy.

    Abstract Objective: To investigate the relationship between average interval time of chemotherapy and prognosis in patients with acute leukemia (AL) during intensive treatment.
    Methods: Data of 92 newly treated adult AL patients who received chemotherapy in The First Hospital of Lanzhou University from January 2010 to June 2019 were analyzed retrospectively. The patients were divided into groups according to the average interval time of chemotherapy during intensive treatment, and its influence on prognosis was analyzed.
    Results: The median interval of chemotherapy during intensive therapy was 38 (20-64) days. According to the average interval of chemotherapy, patients were divided into 4 groups, including < 30 days group, 30-39 days group, 40-49 days group and ≥ 50 days group. The 3-year overall survival (OS) rate of the four groups was (84.9±8.0)%, (73.5±8.7)%, (56.5±11.1)% and (41.8±13.6)%, respectively (P=0.008). The 3-year progression-free survival (PFS) rate of the four groups was (63.6±11.1)%, (52.8±10.2)%, (38.2±10.8)% and (14.0±9.0)%, respectively (P=0.001). After comparison between the 4 groups, it was found that OS and PFS in ≥ 50 days group were significantly shorter than those in < 30 days group (P<0.008). Multivariate analysis showed that risk stratification and average chemotherapy interval ≥ 50 days were the common adverse factors affecting OS and PFS.
    Conclusion: The average chemotherapy interval ≥ 50 days during intensive therapy is an independent risk factor affecting the prognosis and survival of patients with AL. When the bone marrow is completely relieved and the peripheral hemogram recovers to an acceptable level, the consolidation therapy should be started as soon as possible. The interval < 30 days can significantly improve the prognosis compared with the interval ≥ 50 days.

    Abstract Background: Radiofrequency ablation (RFA) and chemotherapy are used to treat lung cancer or pulmonary metastases, but no direct comparison of overall survival (OS) has been published. The present study aimed to assess the OS of RFA and/or chemotherapy in patients with lung cancer or pulmonary metastases who were not candidates for surgical resection.
    Methods: To identify relevant studies, the following databases were electronically searched from their inception to 31 March 2023: PubMed, Embase, Web of Science, Cochrane Library, Scopus, Ovid, ScienceDirect, SinoMed, China National Knowledge Infrastructure Database, Chongqing VIP Chinese Science and Technology Periodical Database, Wanfang Database, LILACS, ClinicalTrials.gov, and Chictr.org. Manual retrieval was also conducted. We used published hazard ratios (HRs) if available or estimates from other survival data.
    Results: A total of 1,387 participants from 14 trials were included in the final analysis. Patients treated with RFA combined with chemotherapy significantly improved OS compared with those treated with chemotherapy alone [HR 0.50, 95% confidence interval (CI) 0.41-0.61; p < 0.00001], with an absolute difference at 12 months of 29.6% (95% CI 23.7-35.5), at 24 months of 19.2% (95% CI 10.1-28.2), and at 36 months of 22.9% (95% CI 12.0-33.7). No statistically significant difference was observed in the subgroups of case type, cancer type, chemotherapy drugs, and tumor size. The HR for OS with RFA plus chemotherapy vs. RFA alone was 0.53 (95% CI 0.41-0.70; p < 0.00001), corresponding to a 27.1% (95% CI 18.3-35.8), 31.0% (95% CI 19.9-41.9), and 24.9% (95% CI 15.0-34.7) absolute difference in survival at 12 months, 24 months, and 36 months, respectively. Subgroup analysis by geographic region and TNM stage showed that RFA combined with chemotherapy still significantly improved OS compared to RFA. The HR of RFA vs. chemotherapy was 0.98 (95% CI 0.60-1.60; p = 0.94), with an absolute difference at 12 months of 1.4% (95% CI -19.2 to 22.1), at 24 months of 7.8% (95% CI -11.3 to 26.8), and at 36 months of 0.3% (95% CI -13.2 to 13.8). The overall indirect comparison of OS for RFA vs. chemotherapy was 0.95 (95% CI 0.72-1.26; p = 0.74). Data on progression-free survival were not sufficiently reported.
    Conclusion: RFA combined with chemotherapy might be a better treatment option for patients with lung cancer or pulmonary metastases than chemotherapy alone or RFA alone. The comparison between RFA and/or chemotherapy remains to be specifically tested.

    Abstract Background: Data with fine granularity about COVID-19-related outcomes and risk factors were still limited in the idiopathic inflammatory myopathies (IIMs) population. This study aimed to investigate clinical factors associated with hospitalized and severe COVID-19 in patients with IIMs, particularly those gauged by myositis-specific antibodies.
    Methods: This retrospective cohort study was conducted in the Renji IIM cohort in Shanghai, China, under an upsurge of SARS-CoV-2 omicron variant infections from December 2022 to January 2023. Clinical data were collected and analyzed by multivariable logistic regression to determine risk factors. High-dimensional flow cytometry analysis was performed to outline the immunological features.
    Results: Among 463 infected patients in the eligible cohort (n=613), 65 (14.0%) were hospitalized, 19 (4.1%) suffered severe COVID-19, and 10 (2.2%) died. Older age (OR=1.59/decade, 95% CI 1.18 to 2.16, p=0.003), requiring family oxygen supplement (2.62, 1.11 to 6.19, 0.028), patients with anti-synthetase syndrome (ASyS) (2.88, 1.12 to 7.34, 0.027, vs. other dermatomyositis), higher IIM disease activity, and prednisone intake >10mg/day (5.59, 2.70 to 11.57, <0.001) were associated with a higher risk of hospitalization. Conversely, 3-dose inactivated vaccination reduced the risk of hospitalization (0.10, 0.02 to 0.40, 0.001, vs. incomplete vaccination). Janus kinase inhibitor (JAKi) pre-exposure significantly reduced the risk of severe COVID-19 in hospitalized patients (0.16, 0.04 to 0.74, 0.019, vs. csDMARDs). ASyS patients with severe COVID-19 had significantly reduced peripheral CD4+ T cells, lower CD4/CD8 ratio, and fewer naive B cells but more class-switched memory B cells compared with controls.
    Conclusion: ASyS and family oxygen supplement were first identified as risk factors for COVID-19-related hospitalization in patients with IIMs. JAKi pre-exposure might protect IIM patients against severe COVID-19 complications.

    Abstract Background: Mild cognitive impairment affects 36% of people aged ≥65 years in China, around 50% of whom will develop dementia within 3 years. Early intervention can slow disease progression and delay the onset of dementia; however, whether a multicomponent intervention can decelerate the progression of mild cognitive impairment remains unknown.
    Objective: To evaluate the effects of a multicomponent intervention to slow mild cognitive impairment progression in Chinese patients.
    Design: Randomized controlled trial.
    Setting(s) and participants: This study was conducted in two large regional communities in Guangzhou, China. Patients aged ≥ 65 years diagnosed with mild cognitive impairment were included.
    Methods: A total of 112 eligible participants were assigned to receive either a 6-month multicomponent intervention or usual care from September 2019 until January 2021. Data were collected at the beginning of the study and at 1, 3, and 6 months thereafter. The primary outcomes were cognitive function, comprehensive physical capacity, depression, and quality of life. Analysis followed the intention-to-treat principle. A generalized estimating equation was used to determine intervention effects.
    Results: At baseline, clinical characteristics did not differ significantly between groups. Significant interaction effects between time and group were detected (p < 0.001), indicating that the scores of five outcomes (cognitive function, short physical performance battery, timed up and go test, quality of life, and depression) of intervention and control groups changed differently over time. Participants in the intervention group were found to have a significantly greater improvement in cognitive function, physical function, quality of life, and fewer depression symptoms compared with the control group at baseline and follow-up periods.
    Conclusions: This study demonstrates the beneficial effects of a multicomponent intervention on cognitive function, physical function, depression symptoms, and quality of life in people with mild cognitive impairment in the East Asia region. The effectiveness and feasibility of this intervention program suggest that its application should be promoted in community settings to delay the progression of disease in people with mild cognitive impairment. Registration number:ChiCTR1900026042 Tweetable abstract: The multicomponent intervention improves cognitive/physical function, depression, and quality of life, slowing cognitive impairment progression.

    Abstract The cell division cycle associated 8 (CDCA8) is a crucial component of the chromosome passenger complex (CPC). It has been implicated in the regulation of cell dynamic localization during mitosis. However, its role in hepatocellular carcinoma (HCC) is not clearly known. In this study, data of 374 patients with HCC were retrieved from the Cancer Genome Atlas (TCGA) database. Pan analysis of Gene Expression Profiling Interactive Analysis (GEPIA) database was performed to profile the mRNA expression of CDCA8 in HCC. Then, the Kaplan-Meier plotter database was analysed to determine the prognostic value of CDCA8 in HCC. In addition, samples of tumour and adjacent normal tissues were collected from 88 HCC patients to perform immunohistochemistry (IHC), reverse transcription-quantitative polymerase chain reaction (qRT-PCR) and Western blotting. The results obtained from bioinformatic analyses were validated through CCK-8 assay, EdU assay, colony formation assay, cell cycle assays and Western blotting experiments. Analysis of the Kaplan-Meier plotter database showed that high expression of CDCA8 may lead to poor overall survival (OS, p = 4.06e-05) in patients with HCC. For the 88 patients with HCC, we found that stages and grades appeared to be strongly linked with CDCA8 expression. Furthermore, the high expression of CDCA8 was found to be correlated with poor OS (p = 0.0054) and progression-free survival (PFS, p = 0.0009). In vitro experiments revealed that inhibition of CDCA8 slowed cell proliferation and blocked the cell cycle at the G0/G1 phase. In vivo experiments demonstrated that inhibition of CDCA8 inhibited tumour growth. Finally, blockade of CDCA8 reduced the expression levels of cyclin A2, cyclin D1, CDK4, CDK6, Ki67 and PCNA. And, there is an interaction between CDCA8 and E2F1. In conclusion, this research demonstrates that CDCA8 may serve as a biomarker for early diagnosis and prognosis prediction of HCC patients. In addition, CDCA8 could be an effective therapeutic target in HCC.

    Abstract Background: Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor type 1 blockers (ARBs) are often prescribed for renal transplant recipients (RTRs), but the outcomes of these medications in RTRs remain controversial.
    Methods: The PubMed, Embase, and Cochrane Library databases were systematically searched. Randomized controlled trials investigating the outcomes of ACEI/ARBs in RTRs were included for meta-analysis.
    Results: Twenty-two trials with 2242 patients were identified. After treatment for at least 12 months, ACEI/ARBs were associated with a decline in glomerular filtration rate (GFR) (weighed mean differences [WMD] -5.76 mL/min; 95% confidence intervals [CI]: -9.31 to -2.20) and a decrease in hemoglobin (WMD -9.81 g/L; 95% CI: -14.98 to -4.64). There were no significant differences in mortality between ACEI/ARB and non-ACEI/ARB groups (risk ratio [RR] 0.98, 95% CI: 0.58 to 1.76), nor in graft failure (RR 0.68, 95% CI: 0.38 to 1.32). After short-term treatment (less than 1 year), significant differences were found in changes of 24-hour proteinuria (WMD-0.57 g/d; 95% CI: -0.72 to -0.42) and serum potassium (WMD 0.25 mEq/L; 95% CI: 0.14 to 0.37) in ACEI/ARB groups compared to control arm, while these differences were not confirmed in the long run.
    Conclusion: This meta-analysis indicates ACEI/ARBs may be prescribed to RTRs with GFR and hemoglobin being carefully monitored.

    Abstract Background: Lung cancer has become the leading cause of death in many regions. Carcinogenesis is caused by the stepwise accumulation of genetic and chromosomal changes. The aim of this study was to investigate the chromosome and gene alterations in the human lung adenocarcinoma cell line OM. Methods: We used Giemsa banding and multiplex fluorescence in situ hybridization focusing on the human lung adenocarcinoma cell line OM to analyze its chromosome alterations. In addition, the gains and losses in the specific chromosome regions were identified by comparative genomic hybridization (CGH) and the amplifications of cancer-related genes were also detected by polymerase chain reaction (PCR). Results: We identified a large number of chromosomal numerical alterations on all chromosomes except chromosome X and 19. Chromosome 10 is the most frequently involved in translocations with six different interchromosomal translocations. CGH revealed the gains on chromosome regions of 3q25.3-28, 5p13, 12q22-23.24, and the losses on 3p25-26, 6p25, 6q26-27, 7q34-36, 8p22-23, 9p21-24, 10q25-26.3, 12p13.31-13.33 and 17p13.1-13.3. And PCR showed the amplification of genes: Membrane metalloendopeptidase (MME), sucrase-isomaltase (SI), butyrylcholinesterase (BCHE), and kininogen (KNG). Conclusions: The lung adenocarcinoma cell line OM exhibited multiple complex karyotypes, and chromosome 10 was frequently involved in chromosomal translocation, which may play key roles in tumorigenesis. We speculated that the oncogenes may be located at 3q25.3-28, 5p13, 12q22-23.24, while tumor suppressor genes may exist in 3p25-26, 6p25, 6q26-27, 7q34-36, 8p22-23, 9p21-24, 10q25-26.3, 12p13.31-13.33, and 17p13.1-13.3. Moreover, at least four genes (MME, SI, BCHE, and KNG) may be involved in the human lung adenocarcinoma cell line OM.
