目的 探究预防性静滴钾离子、镁离子对急性心梗后并发室性心律失常的预防作用。方法 选择2015年1月-2018年1月于西宁市第一人民医院进行治疗的78例急性心肌梗死患者为研究对象,按照随机数字表法将其均分为观察组与对照组,每组各39例患者。对照组患者进行常规急性心梗治疗,观察组患者在对照组基础上加用门冬氨酸钾镁进行治疗,对比两组治疗有效率,对比两组治疗前后血液流变学指标纤维蛋白原(Fib)、凝血酶原时间(PT)、血小板计数(Plt),对比两组治疗期间不良反应发生率及心律失常发生率。结果 治疗后,观察组患者治疗有效率为87.18%,对照组为76.92%,两组对比差异具有统计学意义(P<0.05)。治疗前两组患者Fib、PT以及Plt水平对比差异不具有统计学意义;治疗后,两组患者Plt及Fib水平低于治疗前,PT水平高于治疗前,差异有统计学意义(P<0.05);治疗后观察组患者Plt及Fib水平低于对照组,PT水平高于对照组(P<0.05)。观察组患者不良反应发生率稍高于对照组,但对比差异不具有统计学意义。观察组心律失常发生率为7.69%,对照组为15.38%,两组对比差异具有统计学意义(P<0.05)。结论 预防性静滴钾离子与镁离子能够显著降低急性心梗患者心律失常发生率,同时有利于提高治疗有效率,改善其血流变指标,且安全性较高。  相似文献

The aim of this study was determining the effect of acupressure on the severity of pain associated with intramuscular injections of magnesium sulfate administered by the Z-track technique in patients with eclampsia and preeclampsia. Forty-eight patients participated in this single-group clinical trial, which was conducted in three stages. For each patient, three intramuscular injections were administered by the Z-track technique. The first injection was administered by the conventional method. The second injection at a sham control point and the third injection using acupressure (BL32) were administered. Pain severity was measured on a visual analogue scale. The mean pain intensity was 7.22 in the first, 4.75 in the second and 1.94 in the third injections (p < 0.001). The results of the study showed that acupressure at the BL32 point before intramuscular injection of magnesium sulfate significantly reduced the injection-related pain.  相似文献

目的观察槲皮素对低钙高镁饮食大鼠血清矿量和骨代谢水平的改善作用,为骨质疏松临床预防提供参考。方法将60只清洁雄性SD成年黑色大鼠随机等分为空白对照组、模型对照组和槲皮素喂养组,每组20只。空白对照组实验过程中均正常喂养,模型对照组和槲皮素喂养组均适应性喂养2周后,进行低钙高镁(钙5 mg/L,镁60 g/L,蒸馏水溶液作为饮用水)喂养3个月,槲皮素喂养组给予低钙高镁喂养期间同时给予槲皮素(2.64 kg/d)。观察各组大鼠的日常饮食量、饮水量、体重、毛发、毛发色泽、活动等一般情况,分别于低钙高镁喂养前(实验前)和给药喂养3个月时(实验后)两个时刻点进行血清矿量(血钙、血镁、血磷)及骨代谢指标(BALP、CTX-1、BGP、t PINP)测定。结果实验期间,空白对照组、模型对照组和槲皮素喂养组大鼠的日常饮食量、饮水量、体重比较无显著差异(P0.05),但空白对照组、槲皮素喂养组实验大鼠更具活力,毛发更光润。模型对照组大鼠实验后的血钙量、血磷量、BALP均下降,血镁量、BGP、CTX1、t PINP均提升,与实验前比较差异有统计学意义(P0.05)。槲皮素喂养组大鼠实验后的血钙量、血磷量、BALP均显著高于模型对照组大鼠实验后(P0.05),槲皮素喂养组大鼠实验后的血镁量、BGP、CTX1、t PINP均显著低于模型对照组大鼠实验后(P0.05)。结论槲皮素可显著改善低钙高镁饮食大鼠血清矿量和骨代谢水平,可能在低钙高镁交互作用诱导骨质疏松症的预防中起到重要作用。  相似文献

BACKGROUND Bowel preparation in children can be challenging.AIM To describe the efficacy, safety, and tolerability of sodium picosulfate, magnesium oxide, and citric acid(SPMC) bowel preparation in children.METHODS Phase 3, randomized, assessor-blinded, multicenter study of low-volume, divided dose SPMC enrolled children 9-16 years undergoing elective colonoscopy. Participants 9-12 years were randomized 1:1:1 to SPMC ? dose × 2, SPMC 1 dose × 2, or polyethylene glycol(PEG). Participants 13-16 years were randomized 1:1 to SPMC 1 dose × 2 or PEG. PEG-based bowel preparations were administered per local protocol. Primary efficacy endpoint for quality of bowel preparation was responders(rating of ‘excellent' or ‘good') by modified Aronchick Scale. Secondary efficacy endpoint was participant's tolerability and satisfaction from a 7-item questionnaire. Safety assessments included adverse events(AEs) and laboratory evaluations.RESULTS 78 participants were randomized, 48 were 9-12 years, 30 were 13-16 years. For the primary efficacy endpoint in 9-12 years, 50.0%, 87.5%, and 81.3% were responders for SPMC ? dose × 2, SPMC 1 dose × 2, and PEG groups, respectively. Responder rates for 13-16 years were 81.3% for SPMC 1 dose × 2 and 85.7% for PEG. Overall, 43.8% of participants receiving SPMC 1 dose × 2 reported it was ‘very easy' or ‘easy' to drink, compared with 20.0% receiving PEG. Treatment-emergent AEs were reported by 45.5% of participants receiving SPMC 1 dose × 2 and 63.0% receiving PEG.CONCLUSION SPMC was an efficacious and safe for bowel preparation in children 9-16 years, with comparable efficacy to PEG. Tolerability for SPMC was higher compared to PEG.  相似文献

[目的]了解维持性血液透析病人不宁腿综合征(RLS)现状,为透析病人RLS干预提供依据。[方法]采用回顾性研究对华中科技大学同济医学院附属同济医院的维持性血液透析病人135例进行RLS现状调查。RLS诊断标准是按照国际不宁腿综合征研究小组(IRL-SSG)的诊断标准进行诊断。[结果]维持性血液透析病人中RLS的患病率为18.5%(n=25);单因素分析表明,维持性血液透析RLS病人与非RLS病人在性别、高血压、皮肤瘙痒、透析时间、血清镁、血清铁、甲状旁腺素、血清磷等人口学和临床指标比较差异有统计学意义(P<0.05)。多因素Logistic回归模型显示,4个独立影响因素与维持性血液透析病人RLS的发生显著相关,分别为每日饮酒(OR=2.832,95%CI=2.023~3.378),血清铁(OR=1.560,95%CI=1.274~1.740),血清镁(OR=1.927,95%CI=1.792~2.219),女性(OR=1.307,95%CI=1.187~1.534)。[结论]每日饮酒、血清镁、血清铁、女性是维持性血液透析病人RLS的影响因素。因此,临床工作者应针对相关因素制定相关干预措施,降低维持性血液透析病人RLS发生率,提高维持性血液透析病人生活质量。  相似文献

To reduce the drug plasma concentration fluctuation without being destroyed by gastric fluid, novel Esomeprazole magnesium modified-release pellets (EMZ-MRPs) with suitable in vitro release profiles and good in vitro and in vivo correlation (IVIVC) were developed. Fluid-bed was used to obtain EMZ-loaded pellets by spraying drug suspension onto blank sugar pellets. The drug-loaded pellets were subsequently coated with Eudragit® RS30D/RL30D (ERS/ERL) aqueous dispersion to achieve sustained-release (SR) characteristics. Furthermore, the SR pellets were coated with Eudragit® L30D-55 (EL-55) aqueous dispersion to achieve enteric properties. Besides, isolated coating film was necessary between drug layer and SR layer, as well as SR and enteric-coated layer to protect from their possible reaction. The resulting pellets were filled into the hard gelatin capsules for in vitro release processing and single-dose pharmacokinetic study in rats. The optimal formulation achieved good SR feature both in vitro and in vivo with a relative bioavailability of 103.50%. A good IVIVC was characterized by a high coefficient of determination (r?=?0.9945) by deconvolution method. Compared to those of EMZ enteric-coated pellets (EMZ-ECPs, trade name NEXIUM), the in vivo study make known that the EMZ-MRPs with decreased maximum plasma concentration (Cmax), prolonged peak concentration time (Tmax) and mean residence time (MRT), and similar values both area under concentration–time curve from 0 to t (AUC0–t) and 0 to infinity (AUC0–∞). Collectively, these results manifested EMZ-MRPs had a satisfactory sustained-release behavior, a desired pharmacokinetic property, improved in vivo retention and decreased plasma drug concentration fluctuation.  相似文献

Background: Magnesium has been used as degradable fixation material for osteosynthesis, but it seems that mechanical strength is still a current issue in these fixations. The aim of this study was to evaluate the axial pull-out force of compression headless screws made of magnesium alloy during their resorption. Methods: The tests included screws made for osteosynthesis of the mandible head: 2.2 mm diameter magnesium alloy MgYREZr (42 screws) and 2.5 mm diameter polylactic-co-glycolic acid (PLGA) (42 pieces, control). The screws were resorbed in Sørensen’s buffer for 2, 4, 8, 12, and 16 weeks, and force was measured as the screw was pulled out from the polyurethane block. Results: The force needed to pull the screw out was significantly higher for MgYREZr screws than for PLGA ones (p < 0.01). Within eight weeks, the pull-out force for MgYREZr significantly decreased to one third of its initial value (p < 0.01). The dynamics of this decrease were greater than those of the pull-out force for PLGA screws (p < 0.05). After these eight weeks, the values for metal and polymer screws equalized. It seems that the described reduction of force requires taking into account when using magnesium screws. This will provide more stable resorbable metallic osteosynthesis.  相似文献
