ABSTRACT

Objective To develop a pharmacogenomics study of ticagrelor in patients with acute coronary syndrome (ACS), identify the genetic factors that can predict individual differences in antiplatelet aggregation effects of ticagrelor, and provide a reference for the development of individualized regimens for ticagrelor. Methods 75 ACS patients of Chinese Han in a hospital in Fujian province in 2018 who met the entry criteria were recruited. The patient was given the tests for platelet function test, platelet aggregation rate and DNA detection. The whole exon sequencing method (WES) was used to detect the single nucleotide polymorphisms of SLO1B1, UGT2B7, P2Y12, PEAR1, ITGA2B and ITGB3. At the same time, the general clinical data of the patients were collected and recorded. The correlation between antiplatelet aggregation effects of ticagrelor and pharmacogenetic polymorphism was analyzed by one-way analysis of variance, multiple linear regression analysis and binary logistic regression analysis. Results One-way analysis of variance showed that SLCO1B1 rs2306283 mutant allele G could affect the antiplatelet aggregation effect of ticagrelor, the average platelet aggregation rate of patients carrying at least one allele G (AG+GG type) was significantly lower than that of wild homozygotes AA patients (8.07%±6.17% vs 13.88%±6.39%, P≤0.05). However, multivariate regression analysis after adjusting for confounding factors showed that SLCO1B1 rs2306283 mutant allele G was not an independent variable affecting the antiplatelet effects of ticagrelor (P>0.05). Conclusion Single nucleotide polymorphisms of genes related to ticagrelor transport receptors, targets, and platelet membrane receptors (including SLO1B1, UGT2B7, P2Y12, PEAR1, ITGA2B, ITGB3) in ACS patients of Han Chinese in Fujian province will not significantly affect the antiplatelet aggregation effect of ticagrelor, which provides a new treatment option for patients with genetic defects who are not suitable for clopidogrel.

ABSTRACT

BACKGROUND@#Scleroderma is a multisystem disease in which tissue fibrosis is caused by inflammation and vascular damage. The mortality of scleroderma has remained high due to a lack of effective treatments. However, exosomes derived from human umbilical cord mesenchymal stem cells (HUMSCs)-Ex have been regarded as potential treatments for various autoimmune diseases, and may also act as candidates for treating scleroderma. @*METHODS@#Mice with scleroderma received a single 50 lg HUMSCs-Ex. HUMSCs-Ex was characterized using transmission electron microscopy, nanoparticle tracking analysis and nanoflow cytometry. The therapeutic efficacy was assessed using histopathology, immunohistochemistry, immunofluorescence, quantitative real-time polymerase chain reaction, enzyme-linked immunosorbent assay and western blot. @*RESULTS@#HUMSCs-Ex ameliorated the deposition of extracellular matrix and suppressed the epithelial-mesenchymal transition process, and the effects lasted at least three weeks. In addition, HUMSCs-Ex promoted M1 macrophage polarization and inhibited M2 macrophage polarization, leading to the restoration of the balance of M1/M2 macrophages. @*CONCLUSION@#We investigated the potential antifibrotic and anti-inflammatory effects of HUMSCs-Ex in a bleomycininduced mouse model of scleroderma. So HUMSCs-Ex could be considered as a candidate therapy for scleroderma.

ABSTRACT

BACKGROUND: Studies have demonstrated that intermittent high glucose can have a more severe impact on vascular endothelial function in comparison with persistent hyperglycemia.OBJECTIVE: To investigate the effect of intermittent high glucose on the proliferation and apoptosis of endothelial progenitor cells (EPCs) from human peripheral blood in vitro as well as the production of malondialdehyde (MDA) and antioxidant. METHODS: Total mononuclear cells were isolated from human peripheral blood by Ficoll density gradient centrifugation and then the cells were placed on fibronectin-coated culture dishes. After 7 days of culture, the adherent cells were identified as EPCs by laser scanning confocal microscope. The cells were synchronized and then stimulated with glucose 5.5 mmol/L (normal control group), 20 mmol/L (constant high glucose group), and 5.5/20 mmol/L (intermittent high glucose group, 5.5 and 20 mmol/L glucose culture solution was changed every 8 hours) for 72 hours. EPCs proliferation and apoptosis was measured by MTT assay and flow cytometry, respectively. The content of MDA and the activity of superoxide dismutase (SOD) in culture solution were detected with colorimetry.RESULTS AND CONCLUSION: After EPCs were exposed to constant high glucose (20 mmol/L) and intermittent high glucose (5.5/20 mmol/L) for 72 hours, proliferated cells were significantly reduced and the apoptosis rate was significantly increased compared with those exposed to normal glucose (P < 0.01). Furthermore, there was a significant increase in MDA contents as well as a significant reduce in SOD activities in the constant high glucose and intermittent high glucose group (P < 0.01), especially in the latter group. These findings indicated that both intermittent high glucose and constant glucose could inhibit the proliferation and promote the apoptosis of EPCs; however, intermittent high glucose appears to worsen the effects on EPCs. This is maybe due to the increased oxidative stress.

ABSTRACT

OBJECTIVE@#To investigate the effect and mechanism of glucagon like peptide 1(GLP-1)on the proliferation and differentiation of endothelial progenitor cells(EPCs)derived from the peripheral blood.@*METHODS@#Mononuclear cells were isolated from human peripheral blood by density gradient centrifugation. After 7 days of culture,attached cells were stimulated with different cultures of 0.2% BSA,and GLP-1(1,10,and 20 nmol/L). Laser scanning confocal microscope was used to determine the EPCs from human peripheral blood.The activity of EPCs was observed under reverse microscope. MTT was used to determine the proliferation of EPCs. The expression of KDR,Flt-1,VE-cadherin,and eNOS mRNA was detected by RT-PCR.The concentration of serum VEGF was detected by ELISA. The expression of VEGF protein was detected by immunohistochemical SP method. The EPCs cultured in GLP-1 were intervened by VEGFmAb.@*RESULTS@#EPCs was proliferated more in the GLP-1 group(1,10,and 20 nmol/L) than in the control group (P<0.05 or P<0.01). The expression of KDR,FLT-1,VE-cadherin,eNOS mRNA and VEGF protein was higher than that in the control group(P<0.05 or P<0.01). VEGFmAb(100 ng/mL)down-regulated the expression of KDR,Flt-1,VE-cadherin,and eNOS mRNA.@*CONCLUSION@#GLP-1 can promote the proliferation and differentiation of EPCs derived from the peripheral blood by up-regulating VEGF autocrine.

ABSTRACT

Objective To detect the expression of vascular endotheilal growth factor (VEGF), stromal cell-derived factor-1α (SDF-1α), and its receptor CXCR-4 in the retinopathy of diabetic rats, and to explore the relationship between those factors and diabetic-retinopathy(DR). Methods Diabetes was induced in 40 rats with a single intraperitional injection of streptozotocin(STZ). Experimental rats were randomly divided into M1 (diabetic for 1 month), M3 (diabetic for 3 months), and M5 (diabetic for 5 months) groups, and another 10 rats served as a normal control group (NC). Retinal vascular status was observed by transmission electron microscope. After retinal stretched preparation, VEGF, SDF-1α and CXCR-4 immunohistochemistry were done. Retinal VEGF, SDF-1α, and CXCR-4 mRNA were detected by semi-quantitative RT-PCR. Protein expression was measured by Western blot. Results Under transmission electron microscope, change in vascular status was found in M1 to M5 groups, but not in the NC group. The changes became increasingly serious with the prolongation of the disease. By immunohistochemistry, we found the expression of VEGF, SDF-1α, and CXCR-4 on the retina increased gradually. It increased after injecting STZ for 1 month and increased significantly after 5 months.VEGF, SDF-1α, and CXCR-4 mRNA expression increased obviously after injecting STZ for 1 month and increased significantly after 5 months. Western blot showed that protein of VEGF, SDF-1α, and CXCR-4 had no change after injecting STZ for 1 month. It began to increase in the M3 group and increased most in the M5 group. Conclusion The expression of VEGF, SDF-1α, and CXCR-4 on the retina in retinopathy of diabetic rats increases gradually with the prolongation of the disease. It is an important factor for diabetic retinopathy.

ABSTRACT

Objective To explore the relativity of preoperative health status and perioperative com-plication incidence of aged patients. Methods The chnical data of 3108 old aged people (60 and above 60 years old)who were operated from January 2006 to November 2007 was retrospectively analysed. General e-valuated preoperative health status, and summarized perioperative complication incidence. Results Before operation, 68.7% patients had one or more coexist disease, 41.1% patients had two or more coexist dis-eases, 38.7% had three coexist diseases in the meantime. After operation,one or more complications oc-curred in 21.4% (666/3108)patients, 2.8% (88/3108) patients died because of heart,brain,lung, kidney function failure. Conclusions Aged patients have more coexist diseases, the complications and death rates are higher than those in younger patients. The complications are correlated with preoperative health status and coexist diseases. Some factors could influence the patients rehabilitation,such as heart,brain,lung, kidney function, water-electrolyte balance and blood glucose change.
