Background: SM-like (LSM) genes a family of RNA-binding proteins, are involved in mRNA regulation and can function as oncogenes by altering mRNA stability. However, their roles in B-cell progression and tumorigenesis remain poorly understood. Methods: We analyzed gene expression profiles and overall survival data of 123 patients with mantle cell lymphoma (MCL). The LSM index was developed to assess its potential as a prognostic marker of MCL survival. Results: Five of the eight LSM genes were identified as potential prognostic markers for survival in MCL, with particular emphasis on the LSM.index. The expression levels of these LSM genes demonstrated their potential utility as classifiers of MCL. The LSM.index-high group exhibited both poorer survival rates and lower RNA levels than did the overall transcript profile. Notably, LSM1 and LSM8 were overexpressed in the LSM.index-high group, with LSM1 showing 2.5-fold increase (p < 0.001) and LSM8 depicting 1.8-fold increase (p < 0.01) than those in the LSM.index-low group.Furthermore, elevated LSM gene expression was associated with increased cell division and RNA splicing pathway activity. Conclusions The LSM.index demonstrates potential as a prognostic marker for survival in patients with MCL. Elevated expression of LSM genes, particularly LSM1 and LSM8, may be linked to poor survival outcomes through their involvement in cell division and RNA splicing pathways. These findings suggest that LSM genes may contribute to the aggressive behavior of MCL and represent potential targets for therapeutic interventions.

Objective:To establish and validate a reliable and sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the detection of 12 ceramides in human plasma.Methods:From October 2021 to October 2022, 438 apparently healthy individuals were enrolled in the Affiliated Hospitals of Zunyi Medical University for reference intervals of 12 ceramides in this population. Plasma samples were collected, and separated using the ACQUITY UPLC BEH C18 (2.1×50 mm, 1.7 μm) column, deuterated isotopes were used as internal standards. The mobile phase is water (containing 0.1% formic acid) and isopropanol: acetonitrile (1∶1, v/v, containing 0.1% formic acid) at a flow rate of 0.4 ml/min with gradient elution. The detection method was established using the Qlife Lab 9000 Plus triple quadrupole mass spectrometer. The performance of the method was evaluated in terms of linearity, the lower limit of quantification, precision, recovery, and stability.Results:The method passed the performance evaluation in terms of linearity, the lower limit of quantification, recovery, precision, and stability. The intra-and inter-batch precision of the 12 ceramides ranged from 1.3% to 14.3%, the correctness was verified by spiked recovery experiments, and the recoveries ranged from 91.9% to 111.0%. The lower limit of quantification ranged from 0.001 to 0.100 μmol/L. Standard curve showed good linearity (correlation coefficient r>0.990). Stability tests showed that the 12 ceramides were stable in the biological matrix and after processing under different conditions for a specified period of time. The corresponding biological reference intervals were established for each of the 12 ceramides: 0.103-0.326 μmol/L for Cer(d18∶1/16∶0), 0.018-0.098 μmol/L for Cer(d18∶1/18∶0), 0.933-3.919 μmol/L for Cer(d18∶1/24∶0), 0.243-1.072 μmol/L for Cer(d18∶1/24∶1), 0.001-0.007 μmol/L for Cer(d18∶1/14∶0), 0.022-0.095 μmol/L for Cer(d18∶1/20∶0), 0.185-0.835 μmol/L for Cer(d18∶1/22∶0), 0.003-0.022 μmol/L for Cer(d18∶0/16∶0), 0.001-0.016 μmol/L for Cer(d18∶0/18∶0), 0.017-0.156 μmol/L for Cer(d18∶0/24∶0), 0.008-0.074 μmol/L for Cer(d18∶0/24∶1), and 0.106-0.721 μmol/L for LacCer(d18∶1/24∶1). Conclusion:Our study shows that the newly established LC-MS/MS method for the determination of 12 ceramides in human plasma is reliable, and suitable for clinical application.

Purpose: We aimed to evaluate whether the addition of pemetrexed is effective in improving progression-free survival (PFS) in epidermal growth factor receptor (EGFR)–mutated patients with or without concomitant alterations. Materials and Methods: This multicenter clinical trial was conducted in China from June 15, 2018, to May 31, 2019. A total of 92 non–small cell lung cancer (NSCLC) patients harboring EGFR-sensitive mutations were included and divided into concomitant and non-concomitant groups. Patients in each group were randomly treated with EGFR–tyrosine kinase inhibitor (TKI) monotherapy or EGFR-TKI combined with pemetrexed in a ratio of 1:1. PFS was recorded as the primary endpoint. Results: The overall median PFS of this cohort was 10.1 months. There were no significant differences in PFS between patients with and without concomitant and between patients received TKI monotherapy and TKI combined with pemetrexed (p=0.210 and p=0.085, respectively). Stratification analysis indicated that patients received TKI monotherapy had a significantly longer PFS in non-concomitant group than that in concomitant group (p=0.002). In concomitant group, patients received TKI combined with pemetrexed had a significantly longer PFS than patients received TKI monotherapy (p=0.013). Molecular dynamic analysis showed rapidly emerging EGFR T790M in patients received TKI monotherapy. EGFR mutation abundance decreased in patients received TKI combined chemotherapy, which supports better efficacy for a TKI combined chemotherapy as compared to TKI monotherapy. A good correlation between therapeutic efficacy and a change in circulating tumor DNA (ctDNA) status was found in 66% of patients, supporting the guiding role of ctDNA minimal residual disease (MRD) in NSCLC treatment. Conclusion EGFR-TKI monotherapy is applicable to EGFR-sensitive patients without concomitant alterations, while a TKI combined chemotherapy is applicable to EGFR-sensitive patients with concomitant alterations. CtDNA MRD may be a potential biomarker for predicting therapeutic efficacy.

Objective:To explore the TCM syndromes and risk factors of patients with anxiety and/or depression after coronary revascularization through real-world data mining based on the national pilot project of Chinese and Western medicine clinical collaboration for major difficult diseases; To provide clinical evidence and guide practice for the diagnosis and treatment of bicardiac diseases after coronary revascularization.Methods:A retrospective multi-center clinical study was conducted. From September 2018 to December 2019, 577 patients who underwent successful percutaneous coronary intervention in the Department of Cardiovascular Medicine of Affiliated Hospital of Liaoning University of Traditional Chinese Medicine, Department of Cardiovascular Medicine of the People's Hospital of Liaoning Province were enrolled using the collaborative platform system of TCM and Western Medicine Diagnosis and follow-up for coronary disease. Clinical data database was established. Baseline data, TCM syndrome types and elements, coronary angiography and stent implantation status, relevant disease history, Hamilton Anxiety and Depression Scale, etc. were collected. A combination of postoperative phone calls and outpatient visits was performed, with follow-up every 3 months for a total of 1 year. The TCM treatment patterns and risk factors of patients with anxiety and depression after coronary artery revascularization surgery were analyzed and explored.Results:A total of 577 patients were enrolled and 561 patients were followed up. Age distribution: The age of males and females undergoing coronary revascularization due to ACS was (61.80±11.00) years and (68.37±10.13) years, with no statistical significance between groups ( P>0.05), but the age of onset in males tended to be earlier than in females. The distribution pattern of TCM syndrome elements showed that the most deficiency syndrome elements were qi deficiency (61.75%, 176/285), followed by yin deficiency (28.77%, 82/285). The most common excessive symptom was blood stasis (39.13%, 108/276), and the other syndromes were phlegm turbidity (36.23%, 100/276) and qi depression (20.29%, 56/276), etc. The distribution of TCM syndrome types was as follows: in the population with anxiety and depression state of coronary revascularization, the TCM syndrome types with frequency higher than 10% were successively phlegm and blood stasis with depression syndrome, qi deficiency and blood stasis syndrome, heart, gallbladder and qi deficiency and qi-yin deficiency with blood stasis syndrome. Among the people without anxiety and depression, the TCM syndromes with a frequency higher than 10% were heart blood stasis syndrome and qi deficiency and blood stasis syndrome, with statistical significance ( χ2=12.07, P<0.01). Correlation analysis showed that the number of stents, and LDL-C were positive correlated with anxiety and depression( r values were 0.107, 0.118,respectively, P<0.05), and the uric acid was negative correlation ( r=-0.127, P=0.011). Multivariate Cox proportional hazards regression showed the age [ RR (95% CI)=1.052 (1.012-1.094), P=0.010] and diabetes mellitus [ RR (95% CI)=4.561 (1.028-20.238), P=0.046] at the sixth month of treatment. Conclusions:The age of acute coronary syndrome and coronary revascularization is mainly concentrated in patients aged 60-70 years, and male patients tend to have earlier onset than female patients, and the risk of coronary heart disease is relatively high. Qi-deficiency syndrome accounts for the highest proportion, and the most excessive syndrome is blood stasis syndrome. The TCM syndromes with high frequency of anxiety and depression are phlegm and blood stasis with depression syndrome and qi-yin deficiency with blood stasis syndrome. The number of stents implanted and low density lipoprotein cholesterol are positively correlated with postoperative anxiety and depression. Age and diabetes history are independent risk factors for end-point events at about 6 months after treatment.

Objective:Four cases with NLRP3-related autoinflammatory diseases were reported to summarize the clinical characteristics, genotype, and treatment responses of the disease, and to improve clinical pediatricians' understanding of the disease.Methods:A retrospective analysis was performed on 4 cases with NLRP3-related autoinflammatory diseases diagnosed in Children's Hospital of Anhui Province in 2016—2021, and the clinical features and treatment progress of NLRP3-related autoinflammatory diseases were retrospectively analyzed based on the clinical features, gene reports, and literature review.Results:① All 4 cases were male. Cases 1, 2, and 3 had the disease onset after birth, and case 4 had the disease onset 6 months after birth. All showed periodic fever, repeated urticaria-like rash, protruding forehead, and saddle nose. White blood cells count, erythrocyte sedimentation rate, and C-reactive protein were increased during the attack period, and those in the interval period were normal, and antibiotic treatment was ineffective. ② The genetic test of all these 4 children showed NLRP3 mutation. Children 1, 2, and 3 were heterozygous mutations, and their parents were wild-type. The mutation was located at chromosome Chr1: 247587658, exon c913 (exon3). G>A, the 305th aspartic acid (Asp) of the protein was changed to asparagine (Asn) in child 1. The mutation was located at the chromosomal Chr1: 247588072, the nucleic acid was changed to c1327(exon3)T>C, and the amino acid was changed to p.Y443H in cases 2 and 3. Somatic heterozygous mutation was found in case 4, and the child's parents were wild-type. In this case, the mutation was located at chromosomal Chr1: 247587658, exon3 G>A, and the 305th Asp of the protein was changed to Asn. ③Children in cases 1, 2, and 3 were treated with glucocorticoids and non-steroidal anti-inflammatory drugs at the initial stage, but the effects were limited. After receiving IL-1 antagonist treatment fever, skin rash, joint swelling and pain disappeared, and the inflammatory indexes were returned to normal. The child 4 received non-steroidal anti-inflammatory drugs and methotrexate, but he failed to respond to the treatment. Treatment with tocilizumab was not effective, however, fever, skin rash, or joint pain disappeared after treated with Khanna.Conclusion:①NLRP3-related autoinflammatory diseases can cause periodic fever, urticaria, joint involvement, and severe involvement of the central nervous system and organ amyloidosis. Which are early misdiagnosis is prone to systemic juvenile idiopathic arthritis. ②The disease was an inflammatory disease mediated by interleukin-1. At present, non-steroidal anti-inflammatory drug, glucocorticoid and chronic anti-rheumatic drugs have limited effects. IL-1 antagonists are effective and safe in the treatment of the disease.

Objective:To investigate the role of miR-146a in the pathogenesis of systemic juvenile idiopathic arthritis (sJIA) and its clinical significance.Methods:This article is a prospective clinical cohort study.Twenty-six patients with sJIA (14 cases of initial active group and 12 cases of stable group), 15 patients with multijoint juvenile idiopathic arthritis (JIA) and 15 patients with oligojoint JIA diagnosed in the Department of Rheumatology and Immunology of Anhui Provincial Children′s Hospital from June 2018 to December 2020 were enrolled.Twenty healthy controls from the out-patient clinic were also recruited.The expression level of miR-146a in peripheral blood mononuclear cells (PBMCs) of research objects was detected by real-time fluorescence quantitative polymerase reaction (qPCR), and the serum levels of interleukin (IL) - 6, tumor necrosis factor (TNF) - α and IL-1β in sJIA patients and healthy controls were detected by enzyme-linked immunosorbent assay.The expression levels of miR-146a in PBMCs and cytokines among different groups were compared by analysis of variance. Pearson correlation analysis was used to analyze the correlation of the relative expression level of miR-146a in PBMCs with clinical inflammatory indexes and serum cytokines in sJIA patients. Results:(1) The expression level of miR-146a in PBMCs of early sJIA patients was significantly higher than that in the multijoint JIA group and oligojoint JIA group (8.77±3.15 vs.4.40±1.59, 2.55±1.15, t=6.27, 14.23; all P<0.05). The expression level of miR-146a in PBMCs of sJIA active patients was significantly higher than that in sJIA stable patients (8.77±3.15 vs.3.63±1.37, t=10.27, P<0.05). There was no significant difference in the expression level of miR-146a between the sJIA stable group and healthy control group ( P>0.05). (2) The expression levels of IL-1β, IL-6 and TNF-α were significantly higher in sJIA active patients group than those in sJIA stable group[(58.56±17.47) ng/L vs.(26.32±10.54) ng/L, (73.72±11.16) ng/L vs.(23.20±9.12) ng/L, (70.93±19.97) ng/L vs.(24.25±9.49) ng/L, all P<0.05]. There was no significant difference in the expression levels of IL-1β, IL-6 and TNF-α between the sJIA stable group and healthy control group(all P>0.05). (3)The expression of miR-146a in PBMCs of sJIA patients was positively correlated with serum ferritin levels, platelets, erythrocyte sedimentation rates, C-reactive proteins, IL-1β, IL-6 and TNF-α( r=0.542, 0.433, 0.329, 0.306, 0.333, 0.342, 0.319, all P<0.05). Conclusions:miR-146a may be involved in the inflammatory process of sJIA disease.miR-146a can well distinguish sJIA from multijoint JIA and oligojoint JIA.TNF-α, IL-1β and IL-6 are involved in sJIA inflammatory responses.
