Bacillus coagulans alleviates intestinal barrier injury induced by Klebsiella pneumoniae in rabbits by regulating the TLR4/MyD88/NF-κB signalling pathway.

Probiotics effectively alleviate host diarrhoea, but the specific mechanism is not clear. Therefore, we explored the protective mechanism of Bacillus coagulans (BC) on intestinal barrier injury induced by Klebsiella pneumoniae (K. pneumoniae) in rabbits by HE, immunofluorescence and 16S rRNA.

Traditional Chinese medicine combined with chemotherapy for breast cancer after operation: A systematic review and meta-analysis.

Background: This systematic review aims to explore the effect of traditional Chinese medicine combined with chemotherapy on the clinical efficacy of breast cancer postoperative patients, providing theoretical basis for the treatment of breast cancer postoperative patients with traditional Chinese medicine.

Methods: A comprehensive search was conducted on databases such as China National Knowledge Infrastructure, Wanfang Database, VIP Database, Chinese Biomedical Literature Database, PubMed, and the Cochrane Library from their inception to August 2023 to screen RCTs comparing the effect of traditional Chinese medicine combined with chemotherapy with that of chemotherapy alone on the clinical efficacy of breast cancer postoperative patients. The included literature was systematically reviewed.

Clinical implications of residual normal plasma cells within bone marrow across various disease stages in multiple myeloma.

Residual normal plasma cells (NPCs), which compete with tumor plasma cells, play an important role in multiple myeloma. However, large-scale cohort studies investigating residual NPCs, especially at the minimal residual disease (MRD) phase, are currently lacking. In this study, we conducted a comprehensive investigation into the clinical significance of residual NPCs throughout the entire disease course in 1363 myeloma patients from the NICHE cohort (NCT04645199).

Adipose-derived stem cells can alleviate RHDV2 induced acute liver injury in rabbits.

Rabbit hemorrhagic disease virus (RHDV) can cause fatal fulminant hepatitis, which is very similar to human acute liver failure. The aim of this study was to investigate whether adipose-derived stem cells (ADSCs) could alleviate RHDV2-induced liver injury in rabbits. Twenty 50-day-old rabbits were divided randomly into two groups (RHDV2 group, ADSCs + RHDV2 group).

Monitoring Minimal Residual Disease in Patients with Multiple Myeloma by Targeted Tracking Serum M-Protein Using Mass Spectrometry (EasyM).

Purpose: We investigated both the clinical utilities and the prognostic impacts of the clonotypic peptide mass spectrometry (MS)-EasyM, a blood-based minimal residual disease (MRD) monitoring protocol in multiple myeloma.

Experimental Design: A total of 447 sequential serum samples from 56 patients with multiple myeloma were analyzed using EasyM. Patient-specific M-protein peptides were sequenced from diagnostic samples; sequential samples were quantified by EasyM to monitor the M-protein.

Immunophenotypic profile defines cytogenetic stability and unveils distinct prognoses in patients with newly-diagnosed multiple myeloma (NDMM).

Prognostic significance of multiple immune antigens in multiple myeloma has been well established. However, a level of uncertainty remains regarding the intrinsic relationship between immunophenotypes and cytogenetic stability and precise risk stratification. To address these unresolved issues, we conducted a study involving 1389 patients enrolled in the National Longitudinal Cohort of Hematological Diseases in China (NCT04645199).

Selenomethionine attenuates ochratoxin A-induced small intestinal injury in rabbits by activating the Nrf2 pathway and inhibiting NF-κB activation.

The aim of this study was to investigate whether selenomethionine (SeMet) could attenuate intestinal injury in rabbits induced by ochratoxin A (OTA). Sixty 35-day-old IRA rabbits with similar weights were randomly assigned to the control group, OTA group (0.2 mg OTA/kg b.

Clinical Effects of Neoadjuvant Chemotherapy in Treating Breast Cancer.

To explore clinical effects of neoadjuvant chemotherapy (NAC) in treating breast cancer. Retrospective analysis was performed among 26 breast cancer patients receiving NAC. Chemotherapeutic effects were evaluated using Response Evaluation Criteria In Solid Tumors (RECIST), Japanese Breast Cancer Society (JBCS) grading, and Miller and Payne (MP) grading.

The immunophenotypic characteristics and flow cytometric scoring system of acute myeloid leukemia with t(8;21) (q22;q22); RUNX1-RUNX1T1.

Introduction: The translocation t(8;21) is one of the most frequent chromosome translocations in AML. Molecular (cyto)genetics is regarded as the gold standard for diagnosis. However, due to the complicated variety of AML-related genetic abnormalities, comprehensive screening for all of these abnormalities may not be cost-effective.

Elevated neutrophil-to-lymphocyte ratio and monocyte-to-lymphocyte ratio and decreased platelet-to-lymphocyte ratio are associated with poor prognosis in multiple myeloma.

Elevated inflammatory markers are associated with poor outcomes in various types of cancers; however, their clinical significance in multiple myeloma (MM) have seldom been explored. This study investigated the prognostic relevance of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR) in MM. Totally 559 MM patients were included in this study.

The Prevalence of JAK2, MPL, and CALR Mutations in Chinese Patients With BCR-ABL1-Negative Myeloproliferative Neoplasms.

Objectives: To evaluate the mutation frequency of JAK2 V617F, JAK2 exon 12, MPL exon 10, and CALR exon 9 and the value of the combined tests in the diagnosis of BCR-ABL1-negative myeloproliferative neoplasms (MPNs).

Methods: In the current study, mutations of JAK2 V617F, JAK2 exon 12, MPL exon 10, and CALR exon 9 were analyzed in 929 Chinese patients with BCR-ABL1-negative MPN, including 234 cases of polycythemia vera (PV), 428 ETs, 187 PMFs, and 80 unclassifiable MPNs (MPN-Us).

Results: Our result showed that the positive rate of any of four mutations in patients with PV, ET, PMF, and MPN-U was 89.

The impact of clone size on the prognostic value of chromosome aberrations by fluorescence in situ hybridization in multiple myeloma.

Purpose: Accumulating evidence indicates that intratumor heterogeneity is prevalent in multiple myeloma and that a collection of multiple, genetically distinct subclones are present within the myeloma cell population. It is not clear whether the size of clonal myeloma populations harboring unique cytogenetic abnormalities carry any additional prognostic value.

Experimental Design: We analyzed the prognostic impact of cytogenetic aberrations by fluorescence in situ hybridization at different cutoff values in a cohort of 333 patients with newly diagnosed myeloma and 92 patients with relapsed myeloma.

Rabbit antithymocyte globulin as first-line therapy for severe aplastic anemia.

Rabbit antithymocyte globulin (rATG) was proven effective as salvage therapy for refractory aplastic anemia (AA), or for relapse after initial therapy with horse ATG (hATG). Several clinical trials were performed to assess the efficiency of rATG as a first-line therapy for AA patients; however, their results were variable. The aim of the present study was to assess hematologic response and survival in severe AA (SAA) and very severe AA (VSAA) patients treated with rATG and cyclosporin A (CsA) in our center.

Cytogenetic and clinical marks for defining high-risk myeloma in the context of bortezomib treatment.

Multiple myeloma (MM) is a heterogeneous disease, and the benefit from bortezomib treatment is not uniform among all patients subgroups. Currently, little information is available to predict patients response to bortezomib treatment. In this study, we aimed to identify patients benefiting minimally from bortezomib as part of first-line therapy and to define high-risk MM in the context of bortezomib treatment.

Multiple myeloma patients with low proportion of circulating plasma cells had similar survival with primary plasma cell leukemia patients.

The common features shared by primary plasma cell leukemia (pPCL) and multiple myeloma (MM) with circulating plasma cells (CPCs) are peripheral blood invasion and expansion of plasma cells independent of the protective bone marrow (BM) microenvironment niche. However, few studies have addressed the relationship between pPCL and MM with CPCs. Here, we quantitated the number CPCs by conventional morphology in 767 patients with newly diagnosed MM; their clinic features were compared with those of 33 pPCL cases.

Polyclonal serum IgM level identifies a subgroup of multiple myeloma patients with low-risk clinicobiological features and superior survival.

Normal plasma cells (PCs) are either undetectable or outnumbered by the myelomatous PC compartment in bone marrow of multiple myeloma (MM). However, residual normal PCs have been detected in a minority of symptomatic MM patients with superior survival. The number of normal PCs is also an important factor to identify monoclonal gammopathy of undetermined significance (MGUS)-like MM.

Secondary monoclonal gammopathy of undetermined significance is frequently associated with high response rate and superior survival in patients with plasma cell dyscrasias.

Secondary monoclonal gammopathy of undetermined significance (MGUS) is a special phenomenon that occurs during the treatment of multiple myeloma (MM). The incidence, biological characteristics, and prognostic value of secondary MGUS in patients with MM remain undefined. We proceed with a retrospective systematic review of serum immunofixation electrophoresis studies performed in 438 cases of patients with plasma cell dyscrasias, including 409 cases of newly diagnosed MM and 29 cases of primary plasma cell leukemia.

Chromosome 1q21 gains confer inferior outcomes in multiple myeloma treated with bortezomib but copy number variation and percentage of plasma cells involved have no additional prognostic value.

Chromosome 1q21 aberrations have not been yet been made part of routine clinical tests and their effect in multiple myeloma is still under investigation. The prognostic value of copy number variation and percentage of plasma cells involved have remained unclear. In the present study, we analyzed the prognostic value of 1q21 in a series of 290 cases of newly diagnosed multiple myeloma treated in a prospective, non-randomized clinical trial (BDH 2008/02).

t(11;14) multiple myeloma: a subtype associated with distinct immunological features, immunophenotypic characteristics but divergent outcome.

Unlabelled: t(11;14)(q13;q32) is the most common chromosome translocation in multiple myeloma (MM), but a consensus of clinicopathological features and impact on survival is yet to be reached. We analyzed a cohort of 350 patients with various plasma cell malignancies, including newly diagnosed MM (NDMM, n=253), relapsed/refractory MM (RRMM, n=77), as well as primary and secondary plasma cell leukemia (PCL, n=10 and n=10, respectively).

Results: A remarkably higher frequency of t(11;14) was observed in the PCL than in the NDMM.

High-dose cyclophosphamide compared with antithymocyte globulin for treatment of acquired severe aplastic anemia.

A modified regimen of high-dose cyclophosphamide (CTX) plus cyclosporine (CsA) was adopted for patients with severe or very severe aplastic anemia, and the effectiveness was compared with a regimen of antithymocyte globulin (ATG) plus CsA. A total of 121 patients enrolled in this study received either CTX plus CsA (CTX group, 48 cases) or ATG plus CsA (ATG group, 73 cases). The early death rate was 4.

[Effects of concentration of cyclosporine A on the early response to immunosuppressive therapy in severe aplastic anemia].

Objective: To evaluate the effects of cyclosporine A (CsA) whole-blood concentration on the early response to immunosuppressive therapy (IST) in severe and very severe aplastic anemia (SAA/VSAA).

Methods: Ninety SAA/VSAA patients treated with rabbit antithymocyte globulin (ATG) plus CsA as first line therapy in our hospital were retrospectively analysed. CsA levels between the response group and non-response group, and response rates of patients with variant CsA levels were compared respectively.
