京万红软膏上调PDGF mRNA表达改善大鼠缺血合并外伤型糖尿病足的研究

目的考察京万红软膏对大鼠缺血合并外伤型糖尿病足的疗效及作用机制。方法建立糖尿病大鼠模型,在此基础上建立大鼠缺血合并外伤型糖尿病足模型。实验设置4组,每组大鼠15只,分别为假手术组、模型组、京万红软膏组、重组人表皮生长因子外用溶液(rhEGF)组。给药14 d,记录给药前后大鼠体质量、血糖、足部形态及溃疡面积的变化情况。并于给药后取足部溃疡部位组织行HE染色,采用RT-PCR法检测京万红软膏对血小板源性生长因子(PDGF)、血管内皮生长因子(VEGF)及其受体FLT-1 mRNA表达的影响。结果京万红软膏对大鼠缺血合并外伤型糖尿病足具有消肿生肌,促进创面愈合的功效。与模型组相比,京万红软膏组给药14 d后可极显著减少大鼠足部外伤部位的溃疡面积(P0.01);可极显著上调PDGF mRNA的表达(P0.01)。结论京万红软膏对大鼠缺血合并外伤型糖尿病足具有促进伤口愈合的功效,可能与上调PDGF mRNA的表达相关,但对VEGF及其受体Flt-1 mRNA的表达没有影响。     

MMP-9 and MMP-2 regulation in patients undergoing non-oncological and non-vascular elective surgery independent of the use of propofol or sevoflurane

BackgroundThere is debate regarding whether inhaled sevoflurane or intravenous propofol used during anesthesia achieves the best outcome. Propofol has been shown to affect expression of matrix metalloproteinases (MMPs). MMPs are enzymes that play a role in extracellular matrix remodeling, with activity balance disturbances during surgery. The goal of this study was to compare MMP-2/9 concentrations, activity, and tissue inhibitors of metalloproteinases (TIMPs) 1/2 concentrations in blood of who had undergone 2 types of anesthesia: based on volatile sevoflurane and intravenous propofol during non-oncological, non-vascular surgery.Methods39 patients were enrolled into analysis, 20 anesthetized with total intravenous anesthesia with propofol (P), 19 with volatile induction/maintenance of anesthesia with sevoflurane (S). Plasma samples collected before and 24 h after surgery were analyzed for MMP-2/9, and TIMP-1/2 concentrations using ELISAs. Additionally, MMP-2/9 activities were assessed by gelatin zymography.ResultsStudy revealed increased MMP-9 concentration (ELISA) (P:p = 0.011; S:p = 0.001) and activity (zymography) (P:p = 0.004; S:p = 0.008) in both groups 24 h after surgery. We noticed decreased (both groups) MMP-2 concentration (P:p = 0.044; S:p = 0.027) with MMP-2 activity increase (P:p = 0.002; S:p = 0.006) 24 h after surgery. We observed decreased TIMP-1 plasma concentrations (P:p = 0.002; S:p = 0.000) 24 h after procedures, while TIMP-2 plasma levels remain unchanged (P:p = 0.097; S:p = 0.172). There were no differences between concentration and activity of MMPs and TIMPs in regard to anesthetic used. Meperidine administration correlated with lower MMP-9 activity (R=-0.430; p = 0.006).ConclusionsConcluding, neither sevoflurane nor propofol used as anesthetics modulate MMP-2 and MMP-9 concentrations and activities during non-oncological, non-vascular elective surgery. Meperidine seems to decrease MMP-9 activity.     

Mitigation of acetamiprid – induced renotoxicity by natural antioxidants via the regulation of ICAM,NF-kB and TLR 4 pathways

BackgroundAcetamiprid (ACMP) is a member of the neonicotinoid group of insecticides. It is extensively used worldwide. The misuse of ACMP creates danger hazards to human and animal.MethodsACMP induced renal damage evidenced by an increase in kidney injury biomarkers. So the goal of this work is to clarify the reno protective effect of Quercetin (Qrctn) and/or Nano-glutathione (N-Gluta) solely or in combination to counterbalance the danger effect of ACMP. All treatments with the previous agents were coadministered orally with ACMP for one month.ResultsACMP ingestion caused a significant rise in serum creatinin, urea, and uric acid, TNF α along with renal cystatin C, lipid peroxidation and nitric oxide with the concomitant decline in the levels of reduced glutathione and IL-10 levels. Protein expression of ICAM was upregulated as well as mRNA expression of NF-κB while mRNA expression of Nrf2 was down-regulated. Immune histochemistry of TLR 4 revealed strong immune reaction. The administration of Qrctn or N-Gluta either individually or together modulated all the preceding aforementioned parameters.ConclusionFascinatingly Qrctn and N-Gluta combination was the most powerful regimen to frustrate ACMP reno-toxicity and may be deliberate as a hopeful applicant for renal therapy.

鸭源H7N9亚型禽流感病毒感染SPF鸡转录组学分析

目的 为了分析鸭源H7N9亚型禽流感病毒感染SPF鸡后宿主基因表达水平的变化。方法 以鸭源H7N9亚型禽流感病毒感染SPF鸡,收集肺脏进行高通量测序。结果 与对照组相比,感染组得到差异表达基因740个,其中上调基因有602个,下调基因有138个。GO条目分析发现,差异基因主要涉及免疫应答反应和炎症反应等。经KEGG 数据库比对注释及富集分析显示有7个通路富集显著,其中Toll-like信号通路有11个基因表达上调,分别为IL-6、TLR4、PIK3、IRF7、MD-2、IRF5、MYD88、CD86、STAT1、TLR2和CCL4,NOD-like受体信号通路有7个基因表达上调,分别为IRF7、CTSB、P2RX7、CYBB、PSTPIP1、HSP90AA1和NAMPT。结论 鸭源H7N9亚型病毒感染SPF鸡后,免疫相关基因表达明显增强。在Toll-like信号通路中, TLR4在MD-2的协助下被激活,随后依赖MYD88途径激活下游的IRF5,继而引起CCL4、IL-6显著表达。同时NLRP3炎症体在H7N9亚型病毒感染过程中也发挥着重要作用。
