Correlation between monocyte to high-density lipoprotein cholesterol ratio and insulin resistance in male patients with type 2 diabetes mellitus combined with metabolic-related fatty liver disease / 中国热带医学

@#Abstract: Objective　To explore the correlation between monocyte to high-density lipoprotein cholesterol ratio (MHR) and insulin resistance (IR) in male patients with type 2 diabetes mellitus (T2DM) combined with metabolic-related fatty liver disease (MAFLD). Methods A total of 454 male patients with T2DM combined with MAFLD in National Metabolic Management Center (MMC) of the Affiliated Hospital of Jiangsu University from May 2018 to July 2020 were enrolled. The general clinical data of subjects were collected, blood routine and biochemical indexes were tested, homeostasis model insulin resistance index (HOMA-IR) was calculated, visceral fat area (VFA) and subcutaneous fat area (SFA) were measured. Accordingtothe MHR quartile, patients were divided into group Q1 (MHR≤0.38), group Q2 (0.38<MHR≤0.48), group Q3 (0.48<MHR≤0.64) and group Q4 (MHR>0.64) to compare the differences in measured indicators above. In addition, patients were divided into two groups according to HOMA-IR, HOMA-IR<2.5 and HOMA-IR≥2.5, and the differences in MHR were compared. Results The patients were divided into four groups according to MHR:group Q1 (n=115), group Q2 (n=110), group Q3 (n=120) and group Q4 (n=109). Fasting insulin (FINS) were respectively 6.17(4.20,9.76), 7.73(4.94,10.66), 8.92(5.32,11.33) and 9.13(5.25,12.27) mU/L, 2-hour postprandial insulin were 22.75(12.87,39.59), 27.55(16.44,39.77), 30.98(17.46,43.11) and 31.28(18.54,45.92) U/L. HOMA-IR were 3.12(1.63,4.25), 3.72(2.26,4.66), 3.87(2.48,5.44) and 3.95(2.42,5.31). Neutrophil (Neu) were 3.10(2.60,3.70), 3.20(2.50,3.93), 3.60(2.80,4.28), 4.20(3.30,5.00)×109/L. Subcutaneous fat area (SFA) were (181.27±53.60), (192.64±62.41), (199.53±61.40) and (203.69±71.51) cm2. They all increased gradually. However, the levels of high-density lipoprotein cholesterol (HDL-c) [1.18(1.06,1.35), 1.02(0.86,1.17), 0.96(0.80,1.03) and 0.80(0.69,0.92) mmol/L] and low-density lipoprotein cholesterol (LDL-c) [(3.00±0.79), (2.76±0.83), (2.67±0.85) and (2.59±0.92) mmol/L] decreased gradually. Pearson's or Spearman's correlation analysis showed that MHR was positively correlated with FINS, 2-hour postprandial insulin (2hINS), HOMA-IR, VFA and SFA (r=0.190, 0.153, 0.184, 0.114, 0.127, P<0.05). The coronary heart disease history, systolic blood pressure,diastolic blood pressure,fasting plasmaglucose (FPG), FINS, alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood uric acid (Ur), body mass index (BMI), VFA, SFA and MHR of patients in group HOMA-IR≥2.5 were higher than group HOMA-IR<2.5 (P<0.05). Conclusion　MHR is positively correlated with IR in male patients with T2DM combined with MAFLD, and as MHR increases, the degree of IR is higher.

Specific inhibition of Notch1 signaling suppresses properties of lung cancer stem cells

Objective: Lung cancer is the leading cause of cancer-related death worldwide with a relatively low 5-year relative survival rate of 16%. Novel and efficient therapeutic approach for lung cancer is desperately needed. Materials and Methods: Targeting cancer stem cells (CSCs) provides a promising strategy to eradicate malignancies. The Notch signaling pathway plays an important role in the control of cell fates and developmental processes including CSCs. The function of Notch1 in the regulation of CSCs and whether targeting Notch1 could be a potential therapy for lung cancer were explored in this study. Lung CSCs (LCSCs) were isolated from A549 cells and identified as CD44+/CD24– cells by magnetic-assisted cell sorting, then the putative LCSCs were treated with Notch1 inhibitor and Notch1 small interfering RNAs (siRNAs); the growth and proliferation of LCSCs were investigated to test the effect of Notch1 blocking on the growth and viability of LCSCs. Results: CD44+/CD24– cells isolated from A549 cells possessed stem cell-like properties with high expression of Notch1. Blocking Notch1 by inhibitor DAPT or siRNA both inhibited the growth capacity of LCSCs. Conclusion: Our discovery demonstrated a depression of growth in CD44+/CD24– and A549 cells caused by blockade of Notch signaling pathway. Further studies are needed to demonstrate the detailed effects of Notch1 blocking on the LCSCs. Nevertheless, targeting the Notch pathway has exhibited great potential to be an improved lung cancer treatment

Associations Between Knowledge on Optimal Control of Serum Phosphate, Perceived Social Support, Dietary Phosphorus Intake and Phosphate Compliance Among Hemodialysis Patients

@#Introduction: Hyperphosphatemia is common among hemodialysis patients, often accompanies with unfavourable clinical outcomes. Several factors affect phosphate compliance among hemodialysis patients, with lack of such information at the local context. Thus, this cross-sectional study aimed to determine the associations of sociodemographic factors, knowledge on optimal control of serum phosphate, perceived social support from family, dietary phosphorus intake and phosphate compliance among hemodialysis patients. Methods: Structured questionnaire was used to obtain information on socioeconomic factors, knowledge, family social support and dietary phosphorus intakes of hemodialysis patients, with serum phosphate level was used as the surrogate marker for phosphate compliance. Results: A total of 76 patients (Mean age of 52 years old) were recruited. Hyperphosphatemia was prevalent with approximately 60% of the patients failed to achieve the target. Approximately 90% of the patients perceived low level of family social support. Young patients had significant higher serum phosphate compared to their older counterparts (r = -0.297, p =0.009). Serum phosphate was positively correlated with dietary intake of phosphorus, dialysis vintage (r = 0.301, p = 0.006) and comorbidity score (r = 0.325, p = 0.008) while negatively correlated with dialysis dose (r = -0.582, p = 0.002) and family social support (r = -0.263, p = 0.024). Conclusion: The promising role of dietary phosphorus intake in managing hyperphosphatemia deserves further attention. Innovative approaches are needed to promote self-adherence on serum phosphate especially the younger patients. It is imperative to promote family social support in the management of hyperphosphatemia among hemodialysis patients.

Expression of JMJD2A in infiltrating duct carcinoma was markedly higher than fibroadenoma, and associated with expression of ARHI, p53 and ER in infiltrating duct carcinoma.

Jumonji Domain Containing 2A (JMJD2A) may be a cancer-associated gene involved in human breast cancer. With a view to investigating expression of JMJD2A in human breast cancer and benign lesion tissues as well as relationship between JMJD2A and tumor related proteins, histological and immunohistochemical analysis, Western blot and quantitative real-time PCR in infiltrating duct carcinoma and fibroadenoma for JMJD2A and immunohistochemical analysis and quantitative real-time PCR in infiltrating duct carcinoma for tumor related proteins (ARHI, p53, ER, PR and CerbB-2) were performed. Histological examination validated the clinical diagnosis. The JMJD2A positive rate of infiltrating duct carcinoma was significantly higher than fibroadenoma by immunohistochemical analysis. The mean optical density of JMJD2A in infiltrating duct carcinoma was higher than fibroadenoma by western blot. JMJD2A mRNA level in infiltrating duct carcinoma was higher than fibroadenoma by quantitative real-time PCR. Spearman correlation analysis revealed that the expression of JMJD2A was associated with ARHI, p53 and ER from immunohistochemical results respectively. Pearson correlation analysis revealed that the expression of JMJD2A was associated with ARHI, p53 and ER from quantitative real-time PCR results respectively. Expression of JMJD2A in infiltrating duct carcinoma was higher, and associated with ARHI, p53 and ER. The results may take JMJD2A as a potential diagnostic and therapeutic target in human breast cancer.

Transforming growth factor-β in graft vessels: histology and immunohistochemistry

OBJECTIVES: The biological functions of transforming growth factor-β signaling that involves Smad proteins have not been previously investigated with respect to coronary artery bypass grafts. The aim of the present study was to observe the immunostaining of proteins that are related to this signaling pathway. METHODS: Fifteen remnants of coronary artery bypass grafts, including nine saphenous veins, three radial arteries and three mammary arteries, were collected from 12 patients who were undergoing coronary artery bypass. Hematoxylin and eosin, Masson's trichrome, and immunohistochemical staining of transforming growth factor-β1, type I receptor of transforming growth factor-β, Smad2/3, Smad4, and Smad7 were performed. RESULTS: The saphenous veins showed more severe intimal degeneration, more severe smooth muscle cell proliferation and more collagen deposition than the arterial grafts, as evidenced by hematoxylin and eosin and Masson's trichrome stainings. Immunohistochemical assays demonstrated that the majority of the transforming growth factor-β1 signaling cytokines were primarily localized in the cytoplasm in the medial layers of all three types of grafts, whereas ectopic transforming growth factor-β1, type I receptor of transforming growth factor-β, and Smad7 overexpressions in the interstices were observed particularly in the saphenous vein and radial arterial grafts. CONCLUSION: Enhanced transforming growth factor-β1 signal transduction with medial smooth muscle cell proliferation and ectopic transforming growth factor-β1, the presence of the type I receptor of transforming growth factor-β, and Smad7 overexpressions in the extracellular matrix may provide primary evidence for early or late graft failure.
