Gaucher disease is an autosomal recessive genetic disorder, with membranoproliferative glomerulonephritis (MPGN) being a rare complication. Here we present a case of type I Gaucher disease complicated with MPGN to improve the understanding of this disease. For patients presenting with abdominal distension, hepatosplenomegaly and myelofibrosis, Gaucher disease should be considered to avoid misdiagnosis and inappropriate treatment. The detection of β-glucosidase, genetic mutation analysis and histopathological examination can play crucial roles in the diagnosis of Gaucher disease. Treatment with glucocorticoids combination with immunosuppressants can improve patient's prognosis.
2.Regulatory mechanism of urolithin B in osteoclastic differentiation of bone marrow-derived macrophages
Chinese Journal of Tissue Engineering Research 2025;29(11):2201-2209
BACKGROUND:Urolithin B plays an important role in regulating the body's immune response and has antioxidant,anti-cancer and anti-inflammatory properties.Notably,urolithin B has been reported to have inhibitory effects on osteoclast differentiation of Raw 264.7 cells.However,a more comprehensive understanding of its specific mechanism of action in the context of osteoclast differentiation in bone is worth exploring.Systematic research on the regulatory mechanisms of osteoclast overactivation can help to explore new therapeutic targets,screen and develop safer and more effective therapeutic drugs,and provide new ideas to block the overactivation of osteoclasts. OBJECTIVE:By establishing an in vitro osteoclast differentiation model using bone marrow-derived macrophages,to investigate the effect of urolithin B on nuclear factor-κB receptor-activating factor ligand-mediated osteoclast differentiation and to systematically analyze its mechanism of action. METHODS:(1)The safe working concentration of urolithin B was screened by cell counting kit-8 method.(2)Different concentrations of urolithin B(0,12.5,25,and 50 μmol/L)were used to intervene with the osteoclast differentiation of bone marrow-derived macrophages,and the number of osteoclasts and the size of osteocytes were observed using tartrate-resistant acid phosphatase staining.(3)Different concentrations of urolithin B(0,12.5,25,and 50 μmol/L)were used to intervene with the osteoclast differentiation of bone marrow-derived macrophages,and the relative expression levels of osteoclast-specific genes were detected using real-time fluorescence quantitative PCR.(4)The effect of urolithin B on the P65 and ERK signaling pathways of bone marrow-derived macrophages was observed by western blot.(5)The effect of urolithin B on the key transcription factors nuclear factor of activated T cells 1 and c-Fos in the osteoclastic differentiation of bone marrow-derived macrophages was detected by western blot. RESULTS AND CONCLUSION:50 μmol/L or lower concentration of urolithin B had no effect on the proliferation of bone marrow-derived macrophages but significantly inhibited osteoclastic differentiation of bone marrow-derived macrophages.Urolithin B mainly inhibited osteoclastic differentiation of bone marrow-derived macrophages in pre-medium term.Urolithin B down-regulated the relative expression levels of osteoclast specific genes in bone marrow-derived macrophages.50 μmol/L urolithin B inhibited the phosphorylation levels of P65 and ERK in bone marrow-derived macrophages,which led to the inhibition of osteoclast formation.50 μmol/L urolithin B inhibited the expression of key transcription factors nuclear factor of activated T cells 1 and c-Fos in bone marrow-derived macrophages into osteoclasts.To conclude,urolithin B inhibits bone marrow-derived macrophages from differentiating into osteoclasts by suppressing the expression of downstream osteoclastogenic-related signature genes and downregulating the expression of the important osteoclastogenic transcription factors,nuclear factor of activated T cells 1 and c-Fos,via the P65/ERK signaling axis.

Diuretics are the first-line drugs for the treatment of hypertension. Long-term use of diuretics often causes elevated blood sugar, electrolyte disturbances (most commonly hypokalemia), abnormal lipid metabolism (such as increased triglycerides, elevated cholesterol), increased serum uric acid levels and so on. In order to clarify the specific mechanism of the adverse reactions related to diuretics which are widely used in the treatment of hypertension, many documents have reported the pharmacogenomics research of diuretics-related adverse reactions. This review discusses the related genes and their variants of adverse reactions caused by commonly used diuretics in the treatment of hypertension in hope of providing a basis for the study of individualized use of diuretics.

Membrane creates the functions of protection, supporting, dispersion and separation. More functions can be designed by modifying membrane surface and grafting/loading selective ligands or catalysts on the membrane, thus membrane technology has been widely applied in biological detection, and its application approaches becomes diverse. Rational design of functional membranes can meet the demands in different steps of biological detection process, including sample pretreatment, preparation, response and sensing. This review summarized the functionalization methods of filtration membranes, applications of membrane technology in sample preparation and detection process, as well as the research on the integration of functional membranes. By revisiting the research progress on functional membrane design, preparation and applications for biological detection, it is expected to take better advantage of membrane materials structure and performance for constructing efficient and stable detection platform, which is more "adapted" to the detection environment.

Metabolic syndrome is the fundamental factor in the pathogenesis of a variety of diseases, and it has not yet been fully understood due to its complicated mechanism. Multiple re-searches have implicated that Wnt/β-catenin signaling pathway may have a significant effect on the formation and development of metabolic syndrome. LRP6 is an important co-receptor of Wnt/β-catenin signaling pathway ,and there are some researches im-plicating the correlation between LRP6 and metabolic syndrome. The in-depth research on the gene polymorphism and its modula-tion mechanism can provide new ideas and directions for meta-bolic syndrome therapy.
