Causal relationship between genetically predicted type 2 diabetes mellitus and male infertility.

Background: Diabetes mellitus (DM) stands as the most prevalent endocrine abnormality affecting the physiological systems and organs and impairing the male reproductive functions. Type 2 Diabetes Mellitus (T2DM), accounting for about 90-95% of DM, is closely associated with male infertility. However, the magnitude of the causal relationships between T2DM and male infertility remains unclear.

LncRNA LBX2-AS1 inhibits acute myeloid leukemia progression through miR-455-5p/MYLIP axis.

Acute myeloid leukemia (AML) is a common blood cancer primarily affecting the bone marrow and blood cells, which is prevalent among adults. Long non-coding RNAs (lncRNAs) have been shown to play a crucial role in the development and progression of AML. LBX2-AS1 is a recently discovered lncRNA that has been linked to the pathogenesis and progression of several types of cancer.

Gilteritinib-based combination therapy in adult relapsed/refractory FLT3-mutated acute myeloid leukaemia.

Gilteritinib, a potent FMS-like tyrosine kinase 3 (FLT3) inhibitor, was approved for relapsed/refractory (R/R) FLT3-mutated acute myeloid leukaemia (AML) patients but still showed limited efficacy. Here, we retrospectively analysed the efficacy and safety of different gilteritinib-based combination therapies (gilteritinib plus hypomethylating agent and venetoclax, G + HMA + VEN; gilteritinib plus HMA, G + HMA; gilteritinib plus venetoclax, G + VEN) in 33 R/R FLT3-mutated AML patients. The composite complete response (CRc) and modified CRc (mCRc) rates were 66.

[Correlation between Serum Interleukin-33, β-Microglobulin Levels and DS Stage in Patients with Multiple Myeloma].

Objective: To investigate the correlation between serum interleukin-33 (IL-33), βmicroglobulin (β-MG) levels and Durie-Salmon (DS) stage in patients with multiple myeloma (MM).

Methods: 100 MM patients admitted to the First Affiliated Hospital of Fujian Medical University from March 2019 to January 2021 were selected and divided into stage I, stage II and stage III groups according to the DS staging system. A baseline data questionnaire of patients was designed, then the relevant baseline data and laboratory test results of patients were recorded.

Associations of long-term cadmium exposure with peripheral white blood cell subtype counts and indices in residents of cadmium-polluted areas.

Background: Experimental evidence suggests that exposure to cadmium (Cd) could affect immune cells in vivo and in vitro. However, the associations of long-term Cd exposure with white blood cell (WBC) subtype counts and hemogram-derived indices have been rarely investigated. Therefore, we evaluated these relationships in residents of cadmium-polluted areas.

Leukemia cutis with IDH1, DNMT3A and NRAS mutations conferring resistance to venetoclax plus 5-azacytidine in refractory AML.

Recently, novel drugs like venetoclax plus 5-azacytidine (VA) were reported to have promising efficacy in refractory acute myeloid leukemia (AML). However, there are still some cases presented with novel drugs resistance, and its genetics composition and clinical phenotype are urging to study. We described a 58-year-old patient who was resistant to intensive chemotherapy.

Improvement and Evaluation of a Staining Method for Measuring Sperm Lactate Dehydrogenase C4 Activity.

Background: This study sought to improve and evaluate a 2-hydroxyvaleric acid based staining method for detection of lactate dehydrogenase C4 (LDH-C4) activity in human spermatozoa.

Methods: A staining method for measuring sperm LDH-C4 activity with the substrate 2-hydroxyvaleric acid was improved. Expression level of LDH-C4 was assessed by Western blotting.

Pathological Effects of the FMR1 CGG-Repeat Polymorphism (5-55 Repeat Numbers): Systematic Review and Meta-Analysis.

The fragile X mental retardation 1 (FMR1) gene contains a highly polymorphic trinucleotide (CGG) repeat and consists of various allelic forms. Traditionally, 55-200 repeats and over 200 CGG repeats have been highlighted to be associated with ovarian dysfunction and neuro-psychiatric risks. However, previous studies had paid little attention to the allelic forms of 5-55 CGG repeats.

[Advances in the studies of spermatogonial stem cells in primate mammals].

Spermatogonial stem cells(SSCs) are a type of spermatogonial cells that play an important role in the spermatogenesis of males. SSCs not only possess the properties of stem cells but also differentiate into sperm. They are the unique adult stem cells that transmit genetic information to subsequent generations.

[Efficacy of HAA regimen in the treatment of 64 patients with refractory/relapsed acute myeloid leukemia].

Objective: To evaluate the efficacy and safety of the HAA regimen (homoharringtonine,cytarabine and aclarubicin)as salvage chemotherapy in the treatment of refractory/relapsed acute myeloid leukemia (AML).

Methods: We retrospectively analyzed 64 patients with refractory/relapsed AML who received the HAA regimen as salvage chemotherapy. The complete remission (CR)rate was analyzed.
