    • 摘要: 试验旨在探讨白肉灵芝水提物(Ganoderma leucoconetextum aqueous extracts,GLAE)对脑缺血后海马神经元的保护作用及机制.将50只健康大鼠分为对照组、模型组、GLAE低(0.05 mg/(g·BW))、中(0.1 mg/(g·BW))、高(0.2 mg/(g·BW))剂量组.利用双侧颈总动脉夹闭法建立大鼠脑缺血模型,GLAE组灌胃不同剂量的GLAE干预,对照组和模型组灌胃同体积的生理盐水,连续2周.用跳台试验方法检测记忆获得、记忆巩固和记忆再现障碍大鼠的学习记忆能力,HE染色观察大鼠海马组织的病理形态的变化,比色法检测海马组织一氧化氮合酶(nitric oxide synthase,NOS)活性和一氧化氮(nitric oxide,NO)含量,Western blotting和实时荧光定量PCR法分别检测海马组织生长相关蛋白-43(growth associated protein-43,GAP-43)和脑源性神经生长因子(brain derived neurotrophic factor,BDNF)的水平.结果显示,与对照组相比,模型组大鼠跳台试验的逃避潜伏期显著缩短、电击次数显著增加(P<0.05);海马神经元细胞出现明显核固缩、排列松散紊乱等退行性改变,细胞数量显著减少(P<0.05);海马组织NOS活性和NO含量均显著降低(P<0.05);大鼠海马组织GAP-43蛋白表达量显著升高(P<0.05);海马组织BDNF mRNA表达量显著下调(P<0.05).与模型组相比,GLAE干预后,大鼠逃避潜伏期均显著延长、电击次数均显著减少(P<0.05);GLAE高剂量组大鼠CA1区和齿状回锥体神经元细胞形态明显改善,神经元数量显著增加(P<0.05);GLAE低剂量组对NOS活性影响不明显(P>0.05),显著增加NO含量(P<0.05),GLAE中、高剂量组NOS活性和NO含量均显著升高(P<0.05);GLAE低、中、高剂量组海马组织GAP-43蛋白表达量均显著增加(P<0.05);GLAE低、中、高剂量组海马组织BDNF mRNA表达量均显著增加(P<0.05).以上结果表明,GLAE可通过提高NOS活性和NO水平、促进海马神经发生和功能恢复对脑缺血后海马神经元损伤有一定的保护作用,从而改善大鼠认知功能,0.2 mg/g GLAE效果最好.

    • 摘要: 目的 评价辛伐他汀对大鼠随意皮瓣作用时一氧化氮合酶(NOS)及细胞间粘附因子-1(ICAM-1)表达的影响.方法 健康清洁级雄性SD大鼠60只,6周龄,体重(220±20)g,随机分为实验组及对照组各30只,背部制作随意皮瓣模型后,分别通过腹腔注射给予辛伐他汀(5mg/kg,实验组)和等容积的生理盐水(对照组),1次/d,7d后大体观察两组皮瓣的成活情况并计算成活率、皮瓣病理变化,切取皮瓣近、中、远3段长0.5cm、宽0.5cm的全厚皮瓣组织匀浆离心后,检测组织中NOS、ICAM-1的含量.结果 术后7d,皮瓣中、远段组织学病理切片提示,实验组组织中炎症细胞浸润、坏死程度较对照组轻.实验组皮瓣成活率及NOS活性均较对照组高(P<0.05),ICAM-1活性明显低于对照组(P<0.05).结论 辛伐他汀提高随意皮瓣成活率,其机制可能与辛伐他汀增加NOS生成,抑制ICAM-1表达,进而减轻炎性反应有关.

    • 摘要: AIM To investigate the effects of Shuxuening Injection (Ginkgo biloba leaf extract) on serum lactic acid (Lac),soluble CD14-st (Presepsin) and nitric oxide synthase (NOS) levels in sepsis patients.METHODS One hundred and eight patients with sepsis treated by routine treatment in our hospital from Jan.2014 to Oct.2016 were randomly divided into two groups,control group and Shuxuening group (therapy group).Two weeks were one therapeutic course.Before the treatment (the onset of patients within 3 hours),at 6 hours and 5 days after the treatment,Lac and Presepsin levels were detected,and the changes of nitric oxide (NO),NOS,inducible nitric oxide synthase (iNOS) and sequential organ failure assessment (SOFA) score were observed.Incidence of major adverse cardiac events (MACE) and 28-day survival were recorded at the same time.RESULTS Before the treatment,there were no significant differences in SOFA score and the levels of Lac,Presepsin,NO,NOS and iNOS between the two groups (P > 0.05).Six hours after the treatment,the levels of Lac and Presepsin in the therapy group were lower than those in the control group (P < 0.05),both the two groups had lower levels of Lac and Presepsin than those before the treatment (P < 0.05);five days after the treatment,the levels of Lac and Presepsin in the two groups were lower than those at 6 hours after the treatment (P < 0.05),the levels of Lac and Presepsin in the therapy group were lower than those in the control group (P < 0.05).The SOFA score,NO,NOS and iNOS levels after the treatment in the therapy group were lower than those in the control group (P < 0.05).The levels of Lac and Presepsin in sepsis patients were positively correlated with SOFA score (r =0.245,0.261,P =0.011,0.006).The patients in the therapy group had lower incidence of MACE and 28-day mortality rate than those in the control group (P < 0.05).CONCLUSION The therapeutic effect of Shuxuening Injection combined with routine treatment on sepsis patients is superior to that of routine treatment,which can improve the prognosis of patients to a certain extent.%目的 考察舒血宁注射液(银杏叶提取物)对脓毒症患者血乳酸(Lac)、可溶性CD14亚型(Presepsin)、一氧化氮合酶(NOS)水平的影响.方法 我院2014年1月至2016年10月给予常规治疗的108例脓毒症患者随机分成对照组和舒血宁组(治疗组),2周为1个疗程.两组患者均在治疗前(患者发病3h内)及治疗后6h、5d,检测血Lac和Presepsin水平,观察一氧化氮(N0)、NOS、诱导型一氧化氮合酶(iNOS)和序贯器官功能衰竭评分(SOFA)变化,同时记录主要心脏不良事件(MACE)发生率和28 d生存情况.结果 治疗前两组Lac、Presepsin、NO、NOS、iNOS水平及SOFA评分比较无显著差异(P>0.05).治疗后6h,治疗组Lac和Presepsin水平均低于对照组(P<0.05),两组Lac和Presepsin水平均较治疗前降低(P<0.05).治疗后5d,两组Lac和Presepsin水平较治疗后6h降低(P<0.05),治疗组Lac和Presepsin水平低于对照组(P<0.05).治疗组治疗后SOFA评分、NO、NOS和iNOS水平低于对照组(P<0.05).脓毒症患者Lac和Presepsin水平与SOFA评分呈正相关(r=0.245、0.261,P=0.011、0.006).治疗组患者MACE发生率和28 d病死率低于对照组(P<0.05).结论 舒血宁注射液联合常规治疗对脓毒症患者的疗效优于常规治疗,在一定程度上可以改善患者预后.

    • 摘要: Objective: To investigate the relationship of plasma nitric oxide, nitric oxide synthase levels and the severity of acute cerebral infarction in patients. Methods:The study included 126 patients diagnosed with acute cerebral infarction as experimental group, and 78 patients with healthy body as control group. According to CT and the stroke scales, the area of cerebral infarction and neurological function in brain were assessed. Meanwhile, nitric oxide and nitric oxide synthase activity from serum were measured using nitrate reductase method and chemical colorimetric method, And the correlations between the levels of nitric oxide , nitric oxide synthase and the degree of cerebral infarction, and neurological damage were analyzed. Results:Compared with control group, significant increases in nitric oxide and nitric oxide synthase was observed in experimental group (P<0.05). There was significant difference levels of nitric oxide and nitric oxide synthase in the different areas of cerebral infarction and NIHSS scores (P<0.05). Conclusion:these findings suggested the levels of NO and NOS in patients with acute cerebral infarction were significantly increased, which may be associated with the exacerbations of neurological damage. Therefore, the combined detection of NO and NOS may be a more beneficial method to diagnose acute cerebral infarction and determine the patients' condition.%目的:探讨急性脑梗死患者血浆一氧化氮(NO)和一氧化氮合酶(NOS)与病情严重程度的关系。方法:收集确诊急性脑梗死患者126例为实验组,健康体检者78例为对照组,头颅CT测量急性脑梗塞面积,采用脑卒中量表(NIHSS)评分法评价神经功能,分别采用硝酸还原酶法和化学比色法测定血浆NO水平和NOS活性,分析NO和NOS水平与梗死面积及神经功能损害程度的相关性。结果:与健康对照组比较,急性脑梗死组血浆NO和NOS水平均高于对照组(P<0.05);急性脑梗死患者血浆NO和NOS水平在不同的梗死面积以及不同NIHSS评分中的差异均有统计学意义(P<0.05)。结论:急性脑梗死NO和NOS水平均显著升高,可能与其加重脑梗死神经功能损害有关,两者联合检测更有利于急性脑梗死的诊断和病情判断。

Methods:30 cases of SACC from 2006 to 2012 were used to determine the expression of ILK and NOS by immunohistochemistry examination. The correlation of ILK and NOS were statistically analyzed by SPSS software. Results: The positive rate of ILK expression was 76.67%; The positive rate of eNOS expression was 63.33%; The positive rate of iNOS expression was 80%. ILK and iNOS expression manifested significant differences between experiment and control groups;but expression of eNOS did not show statistical difference. No positive correlation of expression of ILK and eNOS in SACC was confirmed. Expression of ILK were negatively correlated with iNOS expression in SACC, r=0.512. Conclusion: The iNOS plays a role that promoting the growth of SACC and tumor angiogenesis, and eNOS effects are not obvious. ILK and iNOS positive correlation may start signal transduction pathways and motivate VEGF expression, thus promote early tumor angiogenesis and formation.
