Effects of bisdemethoxycurcumin promoting neuronal differentiation of neuroblastoma cells in mice and its mechanism / 中国药房

OBJECTIVE To study the effects of the curcumin derivative bisdemethoxycurcumin （BC） promoting neuronal differentiation of neuroblastoma cells Neuro-2a （N2a） in mice and its mechanism. METHODS The effects of BC （1， 2， 4， 6， 8， 10 μmol/L） on the viability of N2a cells were detected by MTT assay to determine the concentration range of drug treatment. The control group， retinoic acid （RA） group （10 μmol/L） and BC groups （1， 2 and 4 μmol/L） were set up， and the length of neural protrusions of the differentiated cells was measured and the cell differentiation rate was calculated after 48 h and 72 h of culture. Compared with 0 min group， Western blot was used to detect the phosphorylation levels of protein kinase B （Akt）， extracellular- signal regulated kinase 1/2 （ERK1/2）， and p38 mitogen-activated protein kinase （p38） proteins in cells treated by 4 μmol/L BC for 5， 15， 30， 60， 120 min. After intervention with inhibitors LY294002 （LY） and PD98059 （PD）， the effects of BC on Akt and ERK1/2 protein phosphorylation levels and promoting neural differentiation were further validated. RESULTS According to the MTT experiment， the BC concentrations for subsequent induction of cell differentiation were determined to be 1， 2， and 4 μmol/L. After 48 hours of differentiation， compared with the control group， the cell differentiation rate in RA group and BC 1， 2 and 4 μmol/L groups， the length of cellular neural processes wjxhhxx413@163.com in the BC 4 μmol/L group significantly increased （P＜0.05 or P＜0.01）；after inducing differentiation of BC for 72 hours，compared with the control group， the cell differentiation rate and the length of cellular neural processes in the RA group， the cell differentiation rate in the BC 4 μmol/L group， and the length of cellular neural processes in the BC 2 μmol/L group all significantly increased （P＜0.05 or P＜0.01）.Compared with the 0 min group， the phosphorylation levels of Akt， ERK1/2， and p38 proteins in cells of the 5， 15， 30， 60 and 120 min groups increased to varying degrees after treated by 4 μmol/L BC， and some differences were statistically significant （P＜0.05 or P＜0.01）. After adding the inhibitor LY/PD， compared with the BC group， the phosphorylation level of ERK1/2 protein in the PD+BC group cells were significantly reduced （P＜0.01）， and the cell differentiation rates in the LY group， LY+BC group， PD group， and PD+BC group was significantly reduced （P＜0.01）. CONCLUSIONS BC promotes N2a cell differentiation mainly by increasing cell differentiation rate and neural protrusion length. The mechanism may be related to the activation of mitogen-activated protein kinase/ ERK and PI3K/Akt signaling pathways.

【Objective】 To investigate the relationship of miRNA gene polymorphisms with blood pressure (BP) responses to the sodium and potassium diet intervention. 【Methods】 In 2004, we recruited 514 participants from 124 families in seven villages of Baoji, Shaanxi Province, China. All subjects were given a three-day normal diet, followed by a seven-day low-salt diet, a seven-day high-salt diet, and finally a seven-day high-salt and potassium supplementation. A total of 19 miRNA single nucleotide polymorphisms (SNPs) were selected for analysis. 【Results】 Throughout the sodium-potassium dietary intervention, the BP of the subjects fluctuated across all phases, showing a decrease during the low-salt period and an increase during the high-salt period, followed by a reduction in BP subsequent to potassium supplementation during the high-salt diet. MiR-210-3p SNP rs12364149 was significantly associated with systolic BP (SBP), diastolic BP (DBP) and mean arterial pressure (MAP) responses to low-salt diet. MiR-4638-3p SNP rs6601178 was significantly associated with SBP while miR-26b-3p SNP rs115254818 was significantly associated with MAP responses to low-salt intervention. In addition, miR-26b-3p SNP rs115254818 was significantly correlated with SBP, DBP and MAP responses to high-salt intervention. MiR-1307-5p SNPs rs11191676 and rs2292807 were associated with SBP and MAP responses to high-salt diet. MiR-4638-3p SNP rs6601178, miR-210-3p SNP rs12364149, miR-382-5p SNP rs4906032 and rs4143957 were significantly associated with SBP response to high-salt diet. In addition, miR-26b-3p SNP rs115254818 was significantly associated with SBP, DBP and MAP responses to potassium supplementation. MiR-1307-5p SNPs rs11191676, rs2292807, and miR-19a-3p SNP rs4284505 were significantly associated with SBP responses to high-salt and potassium supplementation. 【Conclusion】 miRNA gene polymorphisms are associated with BP response to sodium and potassium, suggesting that miRNA genes may be involved in the pathophysiological process of salt sensitivity and potassium sensitivity.

CD38 regulates macrophagic cholesterol efflux by promoting lysosome reformation via TFEB / 中国病理生理杂志

AIM:To explore the effects of CD38 on lysosome reformation and cholesterol efflux in macro-phages.METHODS:Bone marrow-derived macrophages from low-density lipoprotein(LDL)receptor knockout(LDLr-/-)mice were cultured as cell model.Live cell imaging system was applied to evaluate the effect of nicotinic acid adenine di-nucleotide phosphate(NAADP)on lysosome number.ELISA was conducted to measure NAADP level in macrophages.After the cells were treated with nicotinic acid(NA),RT-qPCR was conducted to detect CD38 mRNA expression,and Western blot was conducted to observe CD38 protein expression and phosphorylated transcription factor EB(TFEB)level.Laser scanning confocal microscopy was applied to evaluate the influence of CD38/NAADP signaling on lysosome number and cholesterol egression.RESULTS:NAADP remarkably increased lysosome number(P<0.05),and this effect was significantly inhibited by NAADP antagonist NED-19,Ca2+ chelator BAPTA,and calcineurin inhibitor CsA(P<0.05).CD38 markedly enhanced NAADP synthesis in macrophages(P<0.05).NAADP synthetic substrate NA prominently ele-vated the expression of CD38 mRNA and protein(P<0.05).NA significantly decreased the phosphorylated TFEB level;this effect was also attenuated by NED-19,BAPTA and CsA(P<0.05).Disrupting CD38/NAADP signaling pathway markedly inhibited NA-induced enhancement of lysosome number,lysosomal free cholesterol and cytosol cholesterol ester efflux in macrophages(P<0.05).NA-induced enhancement of lysosome number,lysosomal free cholesterol and cytosol cholesterol ester efflux abolished in LDLr/CD38 DKO macrophages(P<0.05),whereas these effects induced by NA were recovered after CD38 gene rescue.CONCLUSION:CD38 triggers lysosome reformation via TFEB and consequently pro-motes the efflux of lysosomal free cholesterol and cytosol cholesterol ester.

Effect of perioperative hydroxychloroquine on cardiac surgery in patients with systemic lupus erythematosus / 中华胸心血管外科杂志

Objective:To evaluate the effect of perioperative application of hydroxychloroquine on the prognosis of patients undergoing cardiac surgery.Methods:All SLE patients in the Department of Cardiovascular Surgery of the First Affiliated Hospital of Zhengzhou University who took hydroxychloroquine and glucocorticoid for more than 7 days before operation were enrolled in the observation group(28 cases), including 3 males and 25 females, aged(38.3±8.2)years old. Patients who did not use hydroxychloroquine but only used glucocorticoid before operation were included in the control group(24 cases), including 2 males and 22 females, aged(37.9 ±9.8)years old. There was no significant difference in preoperative clinical data between the two groups in terms of sex, age, BMI, course of systemic lupus erythematosus, hemoglobin, albumin, C-reactive protein, ALT, serum creatinine, ejection fraction, diabetes, hypertension, hyperlipidemia, smoking, alcoholism, preoperative atrial arrhythmia, ventricular arrhythmia, atrioventricular block and so on. The constituent ratio of preoperative operation plan was basically the same between the two groups. The postoperative complications and survival of the two groups were compared.Results:There was no significant difference in early clinical indexes between the two groups, such as cardiopulmonary bypass time( t=0.12, P=0.19), chest drainage volume( t=0.30, P=0.77), second thoracotomy hemostasis( χ2=1.17, P=0.46). There was no significant difference in drug-related complications such as new retinopathy, myocardial concentric hypertrophy, atrial arrhythmia( χ2=1.27, P=0.26), ventricular arrhythmia( χ2=0.98, P=0.32), atrioventricular block( χ2=0.06, P=0.82) and other drug-related complications between the observation group and the control group. There was no significant difference between the two groups in postoperative acute heart failure( χ2=1.17, P=0.28), acute liver insufficiency( χ2=1.17, P=0.28), sternal infection and IABP use( χ2=0.47, P=0.50). Compared with the control group, the incidence of acute renal insufficiency after operation was lower in the observation group( χ2=4.51, P=0.04). The incidence of new postoperative pneumonia was lower( χ2=8.26, P=0.01). The length of postoperative antibiotic use, the length of postoperative ICU hospital stay, the postoperative hospital stay and the total cost of hospitalization in the observation group were significantly less than those in the control group( z=2.71, 2.09, 2.02, 2.02, P=0.01, 0.04, 0.04, 0.04). Compared with the control group, the in-hospital mortality rate of patients in the observation group was lower than that in the control group(3.6% vs. 12.5%, χ2=0.47, P=0.50), and the 6-month and 1-year survival rates of the observation group were higher than those of the control group(92.9% vs.83.3%, 92.9% vs.79.2%; χ2=0.41, 2.17; P=0.53, 0.34), but the difference was not statistically significant. Conclusion:Perioperative administration of hydroxychloroquine can significantly reduce the incidence of postoperative acute renal insufficiency and pneumonia, reduce the duration of postoperative antibiotic use, postoperative ICU hospital stay, postoperative hospital stay, and the cost of hospitalization. Hydroxychloroquine may reduce the in-hospital mortality and improve the long-term survival rate after cardiac surgery, but long-term large sample clinical studies are still needed.

Advances in the study of the pathogenesis of squamous cell carcinoma / 中国综合临床

Squamous cell carcinoma, which originates from squamous epithelium or tissue that undergoes squamous epithelial metaplasia, is one of the most common pathological types of solid human carcinoma. Although squamous cell carcinoma can occur in different anatomical locations, its pathogenesis has commonalities and distinctive features. Genetic mutations and abnormal expression of squamous differentiation markers, epigenetic modifications regulating target gene expression, and tumor microenvironment inducing immune escape of cancer cells are all involved in the development of squamous cell carcinoma. At present, great progress has been made in the research on the pathogenesis of squamous cell carcinoma. This article, combined with relevant research in recent years, reviews the pathogenesis of squamous cell carcinoma in terms of genome changes, epigenetic changes, non coding RNA regulation, tumor microenvironment changes and risk factor induction, so as to provide reference for the prevention and treatment of squamous cell carcinoma.

Medication guidelines for glucagon-like peptide-1 receptor agonist （2023 edition） / 中国药房

The prevalence of diabetes in China is increasing year by year， and has become a health issue of close concern to the whole society. Glucagon-like peptide-1 （GLP-1） receptor agonist （GLP-1RA）， as a new class of glucose-lowering drugs， is now widely used in the treatment of type 2 diabetes mellitus （T2DM） because of its significant glucose-lowering efficacy and low risk of hypoglycemia. As the level of evidence for its effects on improving cardiovascular system and renal protection and reducing body mass continues to improve， its status in the treatment guidelines for T2DM is gradually increasing. Currently， nine GLP-1RA drugs have been approved for the clinical treatment of T2DM in China. Although all of these drugs exert hypoglycemic effects based on the activation of GLP-1 receptors in the body， the differences in their own structures and natural GLP-1 amino acid homology lead to large differences in pharmacokinetic parameters and clinical efficacy among different analogs. In order to enable clinicians and pharmacists to have a full understanding of the characteristics and clinical evidence of these analogs and to better perform their therapeutic effects， Liaoning Provincial Pharmaceutical Society organized clinical medicine and pharmacy experts to develop a medication guide for nine GLP-1RA drugs to provide a reference for clinical medication needs and promote rational and standardized use by compiling and summarizing the pharmacological characteristics， clinical applications， adverse reactions， interactions， the medications in special populations and medication management.

Inhibition of gasdermin D-dependent pyroptosis attenuates the progression of silica-induced pulmonary inflammation and fibrosis

Silicosis is a leading cause of occupational disease-related morbidity and mortality worldwide, but the molecular basis underlying its development remains unclear. An accumulating body of evidence supports gasdermin D (GSDMD)-mediated pyroptosis as a key component in the development of various pulmonary diseases. However, there is little experimental evidence connecting silicosis and GSDMD-driven pyroptosis. In this work, we investigated the role of GSDMD-mediated pyroptosis in silicosis. Single-cell RNA sequencing of healthy and silicosis human and murine lung tissues indicated that GSDMD-induced pyroptosis in macrophages was relevant to silicosis progression. Through microscopy we then observed morphological alterations of pyroptosis in macrophages treated with silica. Measurement of interleukin-1β release, lactic dehydrogenase activity, and real-time propidium iodide staining further revealed that silica induced pyroptosis of macrophages. Additionally, we verified that both canonical (caspase-1-mediated) and non-canonical (caspase-4/5/11-mediated) signaling pathways mediated silica-induced pyroptosis activation, in vivo and in vitro. Notably, Gsdmd knockout mice exhibited dramatically alleviated silicosis phenotypes, which highlighted the pivotal role of pyroptosis in this disease. Taken together, our results demonstrated that macrophages underwent GSDMD-dependent pyroptosis in silicosis and inhibition of this process could serve as a viable clinical strategy for mitigating silicosis.

The diagnostic value of glucose transporter 1 level of erythrocyte membrane and glucose uptake rate of erythrocytes in glucose transporter type 1 deficiency syndrome / 中华实用儿科临床杂志

Objective:To explore new methods to assist the diagnosis of glucose transporter type 1 deficiency syndrome (GLUT1-DS).Methods:Sixteen children with epilepsy and/or movement disorder carrying the SLC2A1 mutation who admitted to Department of Pediatrics, the First Medical Center, Chinese People′s Liberation Army General Hospital and Department of Nutrition, Shanghai Deji Hospital from October 2019 to October 2020 were retrospectively analyzed.GLUT1-DS was diagnosed based on clinical phenotype, glucose level in CSF and/or genetic testing results.Forty-four healthy children who underwent physical examination in the First Medical Center, Chinese People′s Liberation Army General Hospital during the same period were selected as healthy control group.Glucose transporter 1 (GLUT1) level on the membrane surface of peripheral red blood cells and erythrocyte glucose uptake rate were measured by flow cytometry and glucose oxidase method, respectively.Their differences between groups were compared by the rank sum test.The receiver operating cha-racteristic (ROC) curve was plotted to assess their diagnostic value. Results:Sixteen children were diagnosed as GLUT1-DS.GLUT1 levels of 16 children with GLUT1-DS were significantly lower than those of healthy control group [17.96% (13.43%, 22.12%) vs.27.93% (24.76%, 34.30%), Z=5.249, P<0.001]. Area under curve (AUC) was 0.946, and weighted Kappa was 0.791 ( P<0.001). The erythrocyte glucose uptake was measured in 12 children with GLUT1-DS, which was significantly lower than that of healthy control group [23.14% (14.80%, 26.45%) vs.27.40% (24.61%, 32.82%), Z=2.366, P=0.018]. AUC and weighted Kappa were 0.724 and 0.344, respectively ( P<0.001), showing a poor consistency. Conclusions:GLUT1 level on the surface of human erythrocyte membrane measured by flow cytometry may be a new method to assist the diagnosis of GLUT1-DS.The erythrocyte glucose uptake rate test requires stricter experimental conditions and needs further investigation.

Clinical and cardiac MR characteristics of heart involvement in patients with Fabry disease / 中华放射学杂志

Objective:To investigate the clinical and cardiac magnetic resonance (CMR) characteristics of heart involvement in patients with Fabry disease (AFD).Methods:From January 2018 to March 2021, eight AFD patients [3 males and 5 females, mean age (50±11) years old, range 26-60 years old] confirmed by genetic testing or pathology in Fuwai Hospital were retrospectively included in this study. At the same time, sixteen patients with hypertrophic cardiomyopathy (HCM) [6 males and 10 females, mean age (46±15) years old] and 16 healthy individuals [6 males and 10 females, mean age (51±11) years old] were included as controls. The clinical baseline data and CMR data of the patients were collected and analyzed. The CMR data were analyzed using the software CVI42, with the corresponding parameters automatically generated. One-way ANOVA or Kruskal-Wallis test was used to compare the differences in the parameters among the three groups. Independent-samples t test, Fisher precise test or Mann-Whitney U test were used for the comparison between each two groups. Results:Statistically significant difference was found in renal insufficiency between the HCM group and the AFD group; No other significant difference was found in other clinical factors and ECG results (all P>0.05). CMR results showed that in the AFD group, there were 5 cases with symmetric or roughly symmetric hypertrophy, and 3 with asymmetric hypertrophy. The late gadolinium enhancement (LGE) showed myocardial enhancement in 5 patients, mainly presenting as multiple intermural enhancement, and partially as local subendocardial enhancement. In the HCM group, fourteen cases suffered mainly asymmetric ventricular septal thickening, with or without thickening of other parts of left ventricular wall; and 2 cases had thickening of middle and distal part of the left ventricle. The LGE showed myocardial enhancement in 14 patients, which manifested as focal or patchy enhancement in hypertrophic myocardium, including focal enhancement in the right ventricular insertion of ventricular septum (more common) and subendocardial enhancement in the middle and far segments of left ventricle. Statistically significant difference was found in the differences between the left atrial anterior posterior diameter, the maximum wall thickness of left ventricular, the left ventricular myocardial mass index (LVMI) and the native T 1 value among the three groups (all P<0.001). However, there was no statistically significant difference in the left atrial anterior posterior diameter and the maximum wall thickness of left ventricular between AFD group and HCM group ( P>0.05). The LVMI in AFD group was higher than that in healthy group and HCM group (all P<0.05). Significant difference was found in the native T 1 value among the three groups, with the native T 1 value of the AFD group [(1 177.4±46.0) ms] was significantly lower than that of the healthy group [(1 244.5±34.3) ms] and the HCM group [(1 278.8±41.6) ms], with ( F=13.10, P<0.001). Conclusions:The clinical characteristics of AFD and HCM are quite similar. When AFD is suspected, CMR imaging should be the first choice for imaging examination. Especially, T 1 mapping imaging can provide important information for the diagnosis of AFD.

Diabetes Mellitus and Cause-Specific Mortality: A Population-Based Study

BACKGROUND: To investigate whether diabetes contributes to mortality for major types of diseases. METHODS: Six National Health and Nutrition Examination Survey data cycles (1999 to 2000, 2001 to 2002, 2003 to 2004, 2005 to 2006, 2007 to 2008, and 2009 to 2010) and their linked mortality files were used. A population of 15,513 participants was included according to the availability of diabetes and mortality status. RESULTS: Participants with diabetes tended to have higher all-cause mortality and mortality due to cardiovascular disease, cancer, chronic lower respiratory diseases, cerebrovascular disease, influenza and pneumonia, and kidney disease. Confounder-adjusted Cox proportional hazard models showed that both diagnosed diabetes category (yes or no) and diabetes status (diabetes, prediabetes, or no diabetes) were associated with all-cause mortality and with mortality due to cardiovascular disease, chronic lower respiratory diseases, influenza and pneumonia, and kidney disease. No associations were found for cancer-, accidents-, or Alzheimer's disease-related mortality. CONCLUSION: The current study's findings provide epidemiological evidence that diagnosed diabetes at the baseline is associated with increased mortality risk due to cardiovascular disease, chronic lower respiratory diseases, influenza and pneumonia, and kidney disease, but not with cancer or Alzheimer's disease.

Objective To investigate the differences in the gene expression profiles between SW480 and SW620 cell lines.Methods A dataset of GDS756 containing the gene expression profiles of SW480 and SW620 was downloaded from the GEO database in NCBI.The differential expression genes between SW480 and SW620 were analyzed with gene set enrichment analysis (GSEA) and leading edge subset analysis.The genes in leading edge subset were re-annotated by FunRich software.The core genes of leading edge subset closely relating to SW480 or SW620 were analyzed with the STRING on-line analytical system.The functional core genes closely relating to SW480 or SW620 were obtained by the combined analysis of the core genes and high frequency genes from leading edge subset.Results GSEA identified 12 significantly enriched gene sets,491 leading edge genes and 7 highly overlapping genes from SW480 and 80 significantly enriched gene sets,870 leading edge genes and 6 highly overlapping genes from SW620.The STRING system identified 5 core genes from SW480 and 8 from SW620.The combined analysis of GSEA and bionetwork obtained 2 functional core genes,TOP2A and CDK1,from SW620.Conclusion The SW480 and SW620 cells with identical genetic background have different functional gene expression profiles,and the functional core genes TOP2A and CDK1 in SW620 cells may be related to the signal pathways of colon cancer metastasis.

Downscaling research of spatial distribution of incidence of hand foot and mouth disease based on area-to-area Poisson Kriging method / 中华流行病学杂志

Objective To understand the spatial distribution of incidence of hand foot and mouth disease (HFMD) at scale of township and provide evidence for the better prevention and control of HFMD and allocation of medical resources.Methods The incidence data of HFMD in 108 counties (district) in Shandong province in 2010 were collected.Downscaling interpolation was conducted by using area-to-area Poisson Kriging method.The interpolation results were visualized by using geographic information system (GIS).The county (district) incidence was interpolated into township incidence to get the distribution of spatial distribution of incidence of township.Results In the downscaling interpolation,the range of the fitting semi-variance equation was 20.38 km.Within the range,the incidence had correlation with each other.The fitting function of scatter diagram of estimated and actual incidence of HFMD at country level was y=1.053 1x,R2=0.99.The incidences at different scale were consistent.Conclusions The incidence of HFMD had spatial autocorrelation within 20.38 km.When HFMD occurs in one place,it is necessary to strengthen the surveillance and allocation of medical resource in the surrounding area within 20.38 km.Area to area Poisson Kriging method based downscaling research can be used in spatial visualization of HFMD incidence.
