Polygonatum sibiricum, as a traditional Chinese medicine with both medicinal and edible properties, has attracted considerable attention due to its functions of nourishing Yin and moistening the lungs, tonifying the spleen and benefiting Qi, and nourishing the kidneys and filling essence. Recent studies have demonstrated that Polygonatum sibiricum plays a significant role in regulating the immune system, effectively enhancing and improving the morphology and function of immune organs, stimulating the proliferation and activation of immune cells, and regulating the secretion and release of immune factors, thereby enhancing the immune function of the body and improving various immune-related diseases. Although a large number of studies have explored the pharmacological effects and mechanisms of P. sibiricum, there has been no systematic review and summary of its immune regulatory activity and mechanisms. Therefore, this article comprehensively reviews the research achievements of P. sibiricum polysaccharides and saponins in the field of immune regulation in recent years, and further sorts out the immune regulatory mechanisms of P. sibiricum in multiple aspects: including increasing the organ index of the spleen and thymus, increasing the number and activity of tumor-suppressive bone marrow hematopoietic stem cells, improving intestinal flora imbalance, regulating the quantity and proportion of T lymphocyte subsets, increasing the level of immunoglobulin, promoting the proliferation of macrophages, enhancing the activity of natural killer cells, increasing the number of white blood cells, and promoting the maturation of dendritic cells, providing a solid theoretical basis and scientific evidence for the research and application of P. sibiricum, and promoting its development and application in traditional Chinese medicine immune enhancers and various functional products.

ObjectiveThe aim of this study was to investigate the prophylactic effects of caloric restriction (CR) on lipopolysaccharide (LPS)-induced septic cardiomyopathy (SCM) and to elucidate the mechanisms underlying the cardioprotective actions of CR. This research aims to provide innovative strategies and theoretical support for the prevention of SCM. MethodsA total of forty-eight 8-week-old male C57BL/6 mice, weighing between 20-25 g, were randomly assigned to 4 distinct groups, each consisting of 12 mice. The groups were designated as follows: CON (control), LPS, CR, and CR+LPS. Prior to the initiation of the CR protocol, the CR and CR+LPS groups underwent a 2-week acclimatization period during which individual food consumption was measured. The initial week of CR intervention was set at 80% of the baseline intake, followed by a reduction to 60% for the subsequent 5 weeks. After 6-week CR intervention, all 4 groups received an intraperitoneal injection of either normal saline or LPS (10 mg/kg). Twelve hours post-injection, heart function was assessed, and subsequently, heart and blood samples were collected. Serum inflammatory markers were quantified using enzyme-linked immunosorbent assay (ELISA). The serum myocardial enzyme spectrum was analyzed using an automated biochemical instrument. Myocardial tissue sections underwent hematoxylin and eosin (HE) staining and immunofluorescence (IF) staining. Western blot analysis was used to detect the expression of protein in myocardial tissue, including inflammatory markers (TNF-α, IL-9, IL-18), oxidative stress markers (iNOS, SOD2), pro-apoptotic markers (Bax/Bcl-2 ratio, CASP3), and SIRT3/SIRT6. ResultsTwelve hours after LPS injection, there was a significant decrease in ejection fraction (EF) and fractional shortening (FS) ratios, along with a notable increase in left ventricular end-systolic diameter (LVESD). Morphological and serum indicators (AST, LDH, CK, and CK-MB) indicated that LPS injection could induce myocardial structural disorders and myocardial injury. Furthermore, 6-week CR effectively prevented the myocardial injury. LPS injection also significantly increased the circulating inflammatory levels (IL-1β, TNF-α) in mice. IF and Western blot analyses revealed that LPS injection significantly up-regulating the expression of inflammatory-related proteins (TNF-α, IL-9, IL-18), oxidative stress-related proteins (iNOS, SOD2) and apoptotic proteins (Bax/Bcl-2 ratio, CASP3) in myocardial tissue. 6-week CR intervention significantly reduced circulating inflammatory levels and downregulated the expression of inflammatory, oxidative stress-related proteins and pro-apoptotic level in myocardial tissue. Additionally, LPS injection significantly downregulated the expression of SIRT3 and SIRT6 proteins in myocardial tissue, and CR intervention could restore the expression of SIRT3 proteins. ConclusionA 6-week CR could prevent LPS-induced septic cardiomyopathy, including cardiac function decline, myocardial structural damage, inflammation, oxidative stress, and apoptosis. The mechanism may be associated with the regulation of SIRT3 expression in myocardial tissue.

Objective:To investigate the safety,efficacy,and prognosis of high-dose melphalan in combination with autologous hematopoietic stem cell transplantation (ASCT) for the treatment of multiple myeloma (MM). Methods:The clinical data of 17 patients with newly diagnosed MM who underwent ASCT as first-line consolidation therapy at the Yijishan Hospital of Wannan Medical College from March 2020 to October 2022 were retrospectively analyzed. The safety,efficacy,and prognosis of this treatment approach were evaluated. Results:Of the 17 patients,10 were male and 7 were female,with a median age of 56 (45-64) years. The stem cell engraftment rate was 100%,with a median neutrophil engraftment time of+10 (9-12) days and a median platelet engraftment time of+12 (10-21) days. The incidence of oral mucositis and intestinal infection after transplantation was 100%,with 2 cases of pulmonary infection,1 case of urinary tract infection,1 case of skin infection,and 11 cases of transient elevation of serum amylase. After transplantation,13 patients achieved a complete response (CR) or better,and the CR rate showed an increasing trend compared to before transplantation (13/17 vs 8/17;P=0.078). The median follow-up time was 18 (6-36) months,and 15 patients survived without progression,1 patient experienced disease progression,and 1 patient died due to clinical relapse and abandonment of treatment. The 2-year overall survival (OS) rate and progression-free survival (PFS) rate were approximately 90.0% and 83.9%,respectively. Conclusion:High-dose melphalan in combination with ASCT as first-line consolidation therapy for MM can enhance the depth of patient response,further improve therapeutic efficacy,and the transplant-related complications are controllable,making it a viable option worth promoting in clinical practice.

Objective:To investigate expression and significance of mitochondrial ribosomal protein L37(MRPL37)in colorectal cancer.Methods:RNA-seq data and clinical information of colorectal cancer patients were obtained from the TCGA and GEO databases to analyze the differ-ential expression,clinicopathological features,and prognosis of MRPL37 in colorectal cancer.En-richment analysis was performed to explore the biological functions and signaling pathways in-volved in MRPL37,and the TISID database was analyzed for the correlation between MRPL37 and immune-infiltrating cells.Results:MRPL37 was found to be significantly overexpressed in colorectal cancer(P<0.05)and was significantly correlated with the T-stage(P=0.0041),N-stage(P=0.0053),and TNM-stage(P=0.0159)of colorectal cancer patients.The enrichment analysis indi-cates that MRPL37 is primarily involved in mitochondrial physiological activities,cell cycle,oxida-tive phosphorylation,and immune pathways in colorectal cancer.Regarding tumor immunity,changes in MRPL37 expression were found to be correlated with changes in multiple types of im-mune cells in the tumor microenvironment.MRPL37 was an independent prognostic factor(P=0.011),and its expression level was positively associated with patient prognosis(P=0.0017).Con-clusion:MRPL37 may serve as a new potential biomarker for colorectal cancer,which can be used in the future to predict patient prognosis and guide precise patient treatment.
