Article Synopsis
  • The study aimed to assess the clinical significance of prothrombin time (PT) and activated partial thromboplastin time (APTT) in patients newly diagnosed with multiple myeloma (MM).
  • Researchers analyzed data from 116 patients and compared those with normal PT/APTT levels to those with prolonged levels, noting differences in factors like age, blood levels, and bleeding events.
  • Results indicated that patients with prolonged PT/APTT were more prone to bleeding, had lower albumin and platelet levels, and shorter overall survival, identifying prolonged PT/APTT and older age as independent risk factors for worse survival outcomes in these patients.

This study explored the impact of different maintenance therapies on survival outcomes in patients with multiple myeloma (MM), focusing on changes in minimal residual disease (MRD) during maintenance. Conducted at a single center, this retrospective study included 259 newly diagnosed MM patients who did not undergo autologous stem cell transplantation (ASCT). The results indicated that patients receiving lenalidomide as maintenance therapy showed significantly better progression-free survival (PFS) and overall survival (OS) compared to those treated with bortezomib or no maintenance therapy.

Article Synopsis
  • The study aims to explore how nicotinamide phosphoribosyltransferase (NAMPT) functions and its potential clinical significance in multiple myeloma (MM).
  • Researchers used techniques like RT-qPCR and Western blot to analyze NAMPT expression in MM cells and normal cells, investigating its role in cell growth and death.
  • Results showed that NAMPT levels were significantly higher in MM cells, promoting cell growth and inhibiting death, with its expression regulated by the IRE1α-XBP1 signaling pathway, which influences how susceptible these cells are to the treatment drug bortezomib.

Objective: To study the expression level of nicotinamide phosphoribosyltransferase (NAMPT) in multiple myeloma (MM), its relationship with clinical indicators, prognosis and potential role.

Methods: Immunohistochemical staining was used to detect the expression of NAMPT in bone marrow biopsies of patients with newly diagnosed multiple myeloma (NDMM) and patients with iron deficiency anemia (IDA) hospitalized during the same period. According to the median expression level of NAMPT, NDMM patients were divided into high expression group and low expression group.

Multiple myeloma (MM) is a common plasma cell malignancy, accounting for the second largest hematological malignancy. Proteasome inhibitors represented by bortezomib (BTZ) have been the main treatment for patients with newly diagnosed and relapsed or refractory myeloma in nearly two decades. Although BTZ has improved the prognosis of MM patients, MM remains incurable in most patients, mainly because MM cells become resistant to BTZ.

Background: Hydrodissection is a widely used technique during radiofrequency ablation (RFA) for benign thyroid nodules. Although it could effectively avoid thermal injury to the surrounding critical structures and achieve complete treatment, routine operation of the remaining needle could cause perithyroidal hemorrhage. In this report, we present 2 cases of perithyroidal hemorrhage during RFA caused by a hydrodissection needle, which have not been reported before.

Objective: To investigate the prognostic value of hemopoietic scoring system composed of hemoglobin (HB), platelet count (PLT) and mean corpuscular volume (MCV) in MM patients and its correlation with curative effect.

Methods: The clinical data of 172 newly diagnosed MM patients treated by bortezomib as the first-line regimen in our hospital from May 2014 to December 2019 were collected, three variables (HB≤100 g/L, PLT≤150×10/L, MCV≥96 fl) were introduced, each variable was distributed 1 score, the patients were divided into four groups (0, 1, 2 and 3 points in group 1, 2, 3 and 4, respectively), and the clinical characteristics and prognosis of the patients in the four groups were analyzed. The initial efficacy evaluation after 3-4 courses of treatment was carried out, and the curative effect of the patients in the different hematopoiesis score groups were compared.

Autoimmune cytopenia is a general term for all hemocytopenia diseases caused by humoral or cellular immunity abnormalities, and its common immune mechanism determines the importance of immunosuppressive therapy. Sirolimus, as an immunosuppressant against of mTOR, induces immune tolerance by adjusting Treg cells, which has application prospect in the treatment of refractory autoimmune cytopenia. This article reviews the mechanism, application, and possible adverse reactions of sirolimus in the treatment of idiopathic autoimmune cytopenia.

To understand the responses of soil extracellular enzyme activities to the desert grassland-shrubland anthropogenic transition, we examined soil properties and six extracellular enzyme activities, in soil under vegetation patches and bare interspaces in desert grassland, grassland edge, shrubland edge, shrubland in a typical anthropogenic desert grassland-shrubland mosaic in desert steppe of eastern Ningxia, China. The six measured enzymes included cellobiohydrolase, β-1,4-xylosidase, β-1,4-glucosidase, β-1,4-N-acetylglucosaminidase, leucine aminopeptidase and alkaline phosphatase. We found that soil moisture, soil organic carbon, total nitrogen, total phosphorus, microbial biomass carbon and microbial biomass nitrogen decreased significantly by 26.

In this study, desert grassland, grassland edge, shrubland edge, shrubland were selec-ted as four transition sites in a nearly 30 years typical desert grassland-shrubland mosaic formed by anthropogenic shrub introduction. Soil properties and soil microbial characteristics under vegetation patches and bare interspace in each site were investigated to examine the responses of soil nitrogen to the desert grassland-shrubland state transition. It was shown that the aboveground biomass increased with transition from desert grassland to shrubland.
