Methods:Human atrial myocytes were isolated by enzyme dispersion method. IKur in human atrial myocytes were recorded by using the whole cell patch clamp. The changes of IKur were compared in the absence and the presence of sodium ferulate. Results:There was no effect of 0.4 g/L sodium ferulate on I-V relation of IKur. However, 0.4 g/L sodium ferulate inhibited IKur to some degrees at each test pulse. The current densities of IKur at +60 mV decreased from 4.997 ± 0.35 PA/PF to 3.331 ± 0.26 PA/PF(n = 6, P < 0.05). The inhibitory effect was concentration-dependent. IC50 was(0.41±0.03)g/L and the Hill coefficient was 0.95±0.05. Conclusion:Sodium ferulate as a potassium channel blocker can inhibit IKur in human atrial myocytes effectively.展开更多

Ferulic acid (FA) is a ubiquitous phenolic acid of low toxicity, and sodium ferulate (SF) is its sodium salt. Our previous studies have revealed that FA and SF show significant protective effect on excitotoxicity, we now test its potential neuroprotective and antidepressant-like effects. MTT assay and morphological analysis by fluorescence microscopy were adopted to measure the neuroprotective effects of SF;forced-swimming, tail-suspension, and chronic mild stress (CMS) tests were performed to assess its antidepressant-like activity. The results showed that SF had protection against H2O2-induced oxidative damage and dexamethasone (DXM)-induced neurotoxicity pheochromocytoma (PC12) cells. Acute administration of SF markedly decreased the duration of immobility during forced-swimming in rats and mice and tail-supension tests in mice. However, SF has no any effects on reserpine-induced hypothermia, 5-hydroxytryptophan-induced head-twitch response, and potentiation of noradrenaline toxicity in mice. Chronic administration of SF reversed the effects of CMS on consumption of food and sucrose solution, weight gain, and histopathology of hippocampus by light microscopy, and potently shortened the immobility time during forced-swimming test following CMS in rats. This study provides evidence that SF possesses obviously antidepressant-like activity, and the antidepressant-like effect may result from its neuroprotective effects.展开更多

Methods: The maternal mice were assigned randomly into seven groups (n = 10 animals in each group): control, 3SF, 20SF, 23SF, MSG, MSG + 3SF, MSG + 20SF, MSG + 23SF groups. The mice at 17 days of pregnancy were treated with or without MSG (2.0 g/kg body weight, ig, once) or/and SF (40 mg/kg body weight, ip), and their offerings treated with or without SF. And then their filial behaviors and hippocampal histopathology were studied. Results: The results showed that maternal, newborn, and both maternal and newborn administration of SF facilitated their filial brain repair, and attenuated the behavioral disorders and histopathological damages of their filial mice in MSG + 3SF, MSG + 20SF, and MSG + 23SF groups in varying degrees. However, the best effects were detected in the filial mice in MSG + 23SF group. Conclusion: Both maternal and newborn administration of SF is conducive to the filial neuronal repair following excitotoxic damages induced by glutamate.展开更多

Our previous studies have revealed that FA shows neuroprotective effect and significant antidepressant- like effect. The aim of this study was to investigate its potential neurogenesis-enhancing effect and its role in repair following stress-induced neuronal damage. MTT assay was performed to measure the effect of SF on the growth of rat pheochromocytoma (PC12) cells;morphological and immunocytochemical meth- ods were used for assessing its differentiation-induc- ing action. Chronic mild stress (CMS) tests were per- formed to establish rat model of depression. The histopathology of animal brains was studied to ana- lyze CMS-induced morphological changes and the effect of SF on the repair of CMS-induced brain in- jury. The expressions of nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) and the proliferation of neural stem cell/neural progenitor cells were assessed in the hippocampi of chronic mild stress (CMS)-induced depression-like model rats by immunohistochemistry and bromodeoxyuridine (BrdU)- incorporation assays, respectively. Our in vitro tests showed that SF promoted the proliferation of PC12 cells in the concentration range of 5 - 320 μM, and induced PC12 cells to differentiate to more mature cells with the morphological characteristics and mo- lecular marker of neuronal-like cells. In vivo tests showed that SF up-regulated the expressions of NGF and BDNF, and induced the proliferation of neural stem cell/neural progenitor cells in the hippocampi of CMS-induced depression-like model rats. This study provides evidences that SF shows neurogenesis-en- hancing effect, and its antidepressant-like effect of SF may be related directly and closely to its above-men- tioned effect.展开更多

Methods: A total of 119 patients with AMI who were treated in our hospital between December 2014 and December 2017 were reviewed and divided into the control group (n=60) who received conventional western medicine +Shenmai injection therapy and the sodium ferulate group (n=59) who received conventional western medicine + sodium ferulate + Shenmai injection therapy. The differences in serum levels of myocardial injury markers, inflammatory mediators and ventricular remodeling-related indexes were compared between the two groups before treatment and after 2 weeks of treatment. Results: Before treatment, serum levels of myocardial injury markers, inflammatory mediators and ventricular remodeling-related indexes were not significantly different between the two groups. After 2 weeks of treatment, serum myocardial injury markers GMP-140, cTnT, MYO, NT-proBNP and H-FABP levels of sodium ferulate group were lower than those of control group;serum inflammatory mediators MCP-1, IL-18 and hs-CRP levels were lower than those of control group;serum ventricular remodeling-related indexes GDF-15, MMP-10 and CgA levels were lower than those of control group whereas IGF-1 level was higher than that of control group. Conclusion: Western medicine combined with sodium ferulate+ Shenmai injection therapy can effectively protect the myocardial function and inhibit the systemic inflammatory response and ventricular remodeling in patients with AMI.展开更多

Methods: A total of 111 patients with DN who were admitted in our hospital from January, 2016 to April, 2017 were included in the study and randomized into the observation group and the control 1 and 2 group with 37 cases in each group. The patients in the control group were given routine blood sugar reducing, blood pressure reducing, and high quality low protein diet. On the above basis, the patients in the control 2 group were orally administrated with atorvastatin before sleep (20 mg).

The fasting peripheral venous blood before and after treatment in the three groups was collected. The glycse oxidase (GOD) method was used to detect FPG. ELISA was used to detect SCr, TGF-β, AngⅡ, CTGF, hs-CRP, TNF-α, and IL-6. RIA was used to detect BUN and 24hUAER. The strengthened chemiluminescence immunoassay was used to detect CⅣ and PCⅢ. MAP was recorded. Results: FPG, MAP, BUN, 24hUAER, and SCr after treatment in the control 2 group were significantly lower than those in the control 1 group. FPG, MAP, BUN, 24hUAER, and SCr after treatment in the observation group were significantly lower than those in the control 2 group. AngⅡ, TGF-β, CTGF, PCⅢ, and CⅣ after treatment in the control 2 group were significantly lower than those in the control 1 group.

文摘目的:探究阿魏酸钠(SF)通过miR-216b-3p/Nrf2通路对缺氧缺血性脑病(HIE)胚胎大鼠大脑的干预作用以及减轻氧化应激损伤的作用机制。方法:将成年雌性SD大鼠和雄鼠,按照3∶1比例合笼获得怀孕的雌鼠。然后将孕鼠分为假手术组(sham)、缺氧缺血性脑病模型组(HIE)、SF低剂量组(HIE+SF-L)和SF高剂量组(HIE+SF-H)。通过无创止血钳夹闭子宫两侧动脉和卵巢血管法制备胚胎大鼠HIE模型。SF治疗组腹膜腔注射SF。采用HE染色观察胚胎大鼠大脑皮质的病理变化;免疫荧光观察核因子红细胞系2相关因子2(Nrf2)、过氧化还原酶1(PRDX1)的表达情况;Western Blot检测胚胎大鼠脑组织中Nrf2和PRDX1蛋白的表达;real time RT-PCR检测miR-216b-3p的表达以及Nrf2和PRDX1的mRNA表达;WST-8法和TBA法检测脑组织中的超氧化物歧化酶(SOD)活性和丙二醛(MDA)含量。结果:与sham组对比,HIE组胚胎大鼠的大脑损伤加重,病理改变明显;HIE组中Nrf2蛋白表达和mRNA水平降低(P<0.05),PRDX1的蛋白水平和mRNA水平显著上调(P<0.05),miR-216b-3p表达水平显著升高(P<0.05);并且Nrf2的平均荧光强度显著降低(P<0.05),PRDX1的平均荧光强度显著增加(P<0.05);SOD活性显著下调,MDA含量显著增加(P<0.05)。与HIE组对比,各剂量SF组的大脑皮质病理结构明显改善,脑损伤减轻;Nrf2和PRDX1的蛋白表达、mRNA水平以及平均荧光强度均显著上升(P<0.05);miR-216b-3p表达水平均显著下调,以SF高剂量组下调最为显著(P<0.05);并且SOD活性显著上调,MDA含量显著下调(P<0.05)。结论:SF通过miR-216b-3p/Nrf2信号通路在HIE的发生发展过程中发挥重要作用,并减轻胚胎大鼠受到的氧化应激损伤。
