| 1 | Relevance of α-defensins(HNP1-3) and defensin β-1 in diabetes显示文摘AIM: To investigate the genetic background of human defensin expression in type 1 and 2 diabetes.METHODS: Associations between DEFA1/DEFA3 gene copy number polymorphism and diabetes as well as between the promoter polymorphisms of DEFB1 and diabetes were studied. The copy number variation of the DEFA1/DEFA3 genes was determined in 257 diabetic patients(117 patients with type 1 and 140 with type 2 diabetes). The control group consisted of 221 age- and gender-matched healthy blood donors. The cumulative copy numbers of the DEFA1/DEFA3 genes were detected by using quantitative PCR analysis. To evaluate the HNP 1-3(human neutrophil peptide 1-3 or α-defensin) levels in the circulation, plasma HNP 1-3 concentrations were measured by ELISA. The expression of DEFA1/A3 in peripheral leukocytes of the diabetic patients was measured by quantitative RT PCR analysis. Three SNPs of the human DEFB1(human defensin β-1) gene: DEFB1 G-20A(rs11362), DEFB1 C-44G(rs1800972) and DEFB1 G-52A(rs1799946) were genotyped by Custom TaqMan? Real Time PCR assay.RESULTS: Significant differences were observed in HNP1-3 levels between the healthy subjects and both groups of diabetic patients. The mean ± SE was 28.78 ± 4.2 ng/mL in type 1 diabetes, and 29.82 ± 5.36 ng/mL in type 2 diabetes, vs 11.94 ± 2.96 ng/mL in controls; P < 0.01 respectively. There was no significant difference between patients with type 1 and type 2 diabetes in the high plasma concentrations of HNP1-3. The highest concentrations of α-defensin were found in diabetic patients with nephropathy(49.4 ± 4.8 ng/mL), neuropathy(38.7 ± 4.8 ng/mL) or cardiovascular complications(45.6 ± 1.45 ng/L). There was no significant difference in the cumulative copy numbers of DEFA1/DEFA3 genes between controls and patients, or between patients with the two types of diabetes. Comparisons of HNP 1-3 plasma level and DEFA1/A3 copy number of the same patient did not reveal significant relationship between defensin-α levels and the gene copy numbers(r2 = 0.01). Similarly, no positive correlation was observed between the copy numbers and the mRNA expression levels of DEFA1/A3. Regarding the C-44G polymorphism of DEFB1, the GG 'protective' genotype was much less frequent(1%-2%) among both groups of patients than among controls(9%).CONCLUSION: Elevated HNP1-3 levels in diabetes are independent of DEFA1/DEFA3 copy numbers, but GG genotype of C-44G SNP in DEFB1 gene may result in decreased defensin β-1 production. | Balázs Csaba Németh Tamás Várkonyi Ferenc Somogyvári Csaba Lengyel Katalin Fehértemplomi Szabolcs Nyiraty Péter Kempler Yvette Mándi | 2014 | World Journal of Gastroenterology2014，20，27： | 4 |
| 2 | Prophylactic transcatheter arterial embolization reduces rebleeding in non-variceal upper gastrointestinal bleeding: A meta-analysis显示文摘BACKGROUND Despite the improvement in the endoscopic hemostasis of non-variceal upper gastrointestinal bleeding(NVUGIB),rebleeding remains a major concern.AIM To assess the role of prophylactic transcatheter arterial embolization(PTAE)added to successful hemostatic treatment among NVUGIB patients.METHODS We searched three databases from inception through October 19th,2020.Randomized controlled trials(RCTs)and observational cohort studies were eligible.Studies compared patients with NVUGIB receiving PTAE to those who did not get PTAE.Investigated outcomes were rebleeding,mortality,reintervention,need for surgery and transfusion,length of hospital(LOH),and intensive care unit(ICU)stay.In the quantitative synthesis,odds ratios(ORs)and weighted mean differences(WMDs)were calculated with the random-effects model and interpreted with 95%confidence intervals(CIs).RESULTS We included a total of 3 RCTs and 9 observational studies with a total of 1329 patients,with 486 in the intervention group.PTAE was associated with lower odds of rebleeding(OR=0.48,95%CI:0.29–0.78).There was no difference in the 30-d mortality rates(OR=0.82,95%CI:0.39–1.72)between the PTAE and control groups.Patients who underwent PTAE treatment had a lower chance for reintervention(OR=0.48,95%CI:0.31–0.76)or rescue surgery(OR=0.35,95%CI:0.14–0.92).The LOH and ICU stay was shorter in the PTAE group,but the difference was non-significant[WMD=-3.77,95%CI:(-8.00)–0.45;WMD=-1.33,95%CI:(-2.84)–0.18,respectively].CONCLUSION PTAE is associated with lower odds of rebleeding and any reintervention in NVUGIB.However,further RCTs are needed to have a higher level of evidence. | Eszter Boros Zoltán Sipos Péter Hegyi Brigitta Teutsch Levente Frim Szilárd Váncsa Szabolcs Kiss FanniDembrovszky Eduard Oštarijaš Andrew Shawyer Bálint Erőss | 2021 | World Journal of Gastroenterology2021，27，40： | 2 |
