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 investigate the role and related mechanism of the soluble guanylate cyclase(sGC)-cGMP-protein kinase G(PKG)signaling pathway in the amelioration of isoproterenol(ISO)-induced cardiac hypertrophy in mice by aqueous extract of Curcuma kwangsiensis root tubers(GYJS).Methods 72 KM male mice were divided randomly into 6 groups:normal,model,propranolol control(40 mg/kg),and GYJS low-(1 g/kg),medium-(2 g/kg),and high-dose(4 g/kg)groups.Mice in the experimental groups were injected subcutaneously with ISO 10 mg/kg on days 1~3 and ISO 5 mg/kg on days 4~14 to establish a mouse cardiac hypertrophy model.4h after each subcutaneous injection of ISO,the mice in each group were administered the corresponding drugs orally for a dosing cycle of 14 days.The hearts were then removed and whole heart and left ventricle weight were measured.Myocardial tissue pathology was observed using hematoxylin and eosin and Masson staining,and sGC subunit beta-1(GUCY1B3)and transforming growth factor(TGF-β1)were detected by immunohistochemistry.Serum lactate dehydrogenase(LDH),creatine kinase(CK),and Nitric Oxide(NO),and myocardial superoxide dismutase(SOD)activity and malondialdehyde(MDA)content were measured using respective kits.Serum cGMP was detected by enzyme-linked immunosorbent assay and quantitative reverse transcription PCR(RT-qPCR),and atrial natriuretic peptide(ANP),brain natriuretic peptide(BNP),GUCY1B3,PKG Ⅰ,and phosphodiesterase(PDE)5A mRNA expression levels were also determined by RT-qPCR.Results Compared with the model group,whole heart and left ventricle weights were significantly reduced in mice treated with propranolol or GYJS(P<0.001 or P<0.0001)and myocardial hypertrophy and myocardial fibrosis were significantly reversed.All the treatments significantly elevated myocardial expression of GUCY1B3(P<0.05 or P<0.01)and significantly reduced expression of TGF-β1(P<0.05 or P<0.01).The myocardial damage markers LDH and CK were significantly reduced(P<0.05 or P<0.01)while NO and cGMP were significantly elevated(P<0.05 or P<0.01),the myocardial oxidative stress indicator MDA was significantly reduced(P<0.05 or P<0.01)and SOD activity was significantly increased(P<0.05 or P<0.01).mRNA levels of the myocardial hypertrophy markers ANP,BNP,and PDE5A were significantly reduced(P<0.05,P<0.01,or P<0.001)and the mRNA levels of GUCY1B3 and PKG Ⅰ were significantly increased(P<0.01 or P<0.001).Conclusions GYJS may improve cardiac hypertrophy by modulating the sGC-cGMP-PKG signaling pathway.

Systemic lupus erythematosus (SLE) is a diffuse, systemic autoimmune disorder that can impact multiple organs and systems, with patients exhibiting abnormal levels of various autoantibodies and immune markers in their serum. It is currently understood that dysregulation of B cells activation plays a pivotal role in the pathogenesis of SLE, as aberrantly activated B cells produce autoantibodies that inflict damage on multiple organs through complement activation and antibody-dependent cell-mediated cyto-toxicity. Traditional therapies for SLE may prove ineffective for certain patients or lead to adverse reactions. In most instances, conventional treatment merely alleviates symptoms and necessitates lifelong immunotherapy. A limited number of clinical cases have explored chimeric antigen receptor T cells (CAR-T) therapy as a potential treatment for autoimmune diseases such as SLE. Research indicates that CAR-T can specifically target CD19 expressed on the surface of B cells and plasma cells, achieving profound depletion while minimizing drug-related side effects. This report details a female patient diagnosed with SLE and lupus nephritis who was successfully treated using dual-targeting B cells maturation antigen CAR-T by our research team; following treatment, she ceased steroid and immunomodulator use, attaining sustained remission without these medications. The patient was a 23-year-old female. Multiple examinations in other hospitals and in our hospital showed positive anti-double-stranded DNA (dsDNA) antibody and low complement C3. Renal biopsy in our hospital showed lupus nephritis Ⅳ-G (A/C), and National Institutes of Health (NIH) activity index (AI) score=4. She was diagnosed with "SLE, lupus nephritis (LN)". She was treated with hormones, immunosuppressants and Chinese medicine, but the effect was not good. After the CAR-T treatment, She stopped using hormones and immune agents and achieved continuous remission with zero hormones and zero immune agents. She became pregnant six months after CAR-T infusion, and gave birth to a healthy full-term, full-weight baby successfully. She is the first patient in China who successfully discontinued hormone, immune preparations and gave birth after CAR-T therapy. During the follow-up of the patient, we found that the immune indexes had basically returned to normal, and the safety was good. It indicates that CAR-T therapy may represent a promising and innovative therapeutic approach for the management of SLE. This offers hope and establishes a precedent for SLE women of childbearing age.

The relationship between pyroptosis and immune microenvironment and disease has received increasing attention. Pyroptosis plays a dual role in anti-tumor immunotherapy by promoting the release of inflammatory factors, forming the tumor microenvironment and suppressing tumour immunity on the one hand, and inducing the tumour inflammatory response to inhibit the proliferation of tumor cells on the other hand. The relationship between pyroptosis, immune microenvironment and tumors is different in different tissues and genetic backgrounds. This article reviews the molecular mechanisms of pyroptosis and the regulatory role of tumor immune microenvironment in hematologic malignancies, with a view to providing ideas for the anti-hematologic malignancies treatment and research based on the target of pyroptosis-regulated immune microenvironment.

ObjectiveTo reveal the effects of different microbial agents on quality of Lycii Fructus by comparing the differences in the contents of multiple types of chemical components in Lycii Fructus after the application of different microbial agents. MethodTaking Ningqi No. 7 as experimental material, four microbial agents, namely Peiyuan combined with Xinterui(TP group), Trichoderma harzianum combined with Bacillus subtilis(BW group), Genwuyou(MT group) and Junyiduo(JYD group), were applied, and no microbial agents was used as the blank group(CK group). Then the contents of total phenolics, total flavonoids, saccharides, amino acids, nucleosides and bases, betaine and other components in Lycii Fructus were determined by ultraviolet spectrophotometry(UV), high performance liquid chromatography(HPLC) and ultra-high performance liquid chromatography-mass spectrometry(UHPLC-MS/MS), and the methods such as multiple comparisons, principal component analysis(PCA) and partial least squares-discriminant analysis(PLS-DA) were used to analyze the effect of different microbial agents on the quality of Lycii Fructus. ResultMicrobial agents had different effects on chemical components of Lycii Fructus. The content of total phenolics was the highest in the TP group, and it varied significantly from the CK group(P<0.05). The total flavonoid content was the highest in the BW group, followed by the TP group. Both polysaccharide and alduronic acid contents were the highest in the JYD group. Betaine content in the TP and BW groups were significantly higher than that in the CK group(P<0.05). For the determined 23 kinds of amino acids, most of them were the lowest in the JYD group, and the highest in the MT group, while the nucleoside bases were higher in the MT and BW groups. It indicated that Lycii Fructus from different treatment groups could be distinguished clearly based on the determined 45 chemical components. The result of PLS-DA showed that the major differential components in each group were polysaccharides, glucose, fructose, betaine, alduronic acid, asparagine, sucrose, threonine, total flavonoids, alanine and total phenolics. The results of PCA composite scores based on the main differential components showed that composite scores of chemical components in each group were BW group>TP group>MT group>CK group>JYD group. ConclusionThe application of microbial agents of BW, TP and MT can promote the quality improvement of Lycii Fructus, and the application of JYD can promote the accumulation of polysaccharides and alduronic acid to a certain extent, but the overall effect on the quality of Lycii Fructus is not clear. This study lays the foundation for the green and healthy development of Lycii Fructus industry.

Reoperation due to degenerated bioprostheses is an important factor of high-risk thoracic surgeries. In 2020 ACC/AHA guideline, Valve in Valve (ViV) was recommended for high-risk patient instead of surgical mitral valve replacement. This report described a 77-year-old male patient with a failed mitral bioprosthetic valve, evaluated at high risk of surgery, received a transvenous, transseptal transcatheter mitral valve replacement (TMVR). Tracheal intubation was removed at CCU 3 h after surgery without discomfort such as polypnea. The patient was transferred out of the CCU and discharged on the 3rd day. Compared with transapical access, transvenous transseptal access was less invasive, with shorter duration in CCU and hospitalization.
