前列腺素E1联合硫酸镁在肺心病急性加重期应用中的临床研究

Objective To study the curative effect and medchanism of action about prostaglandin E1 and magnesium sulfate in the treatment of chronic pulmonary heart disease in the aggravation period. Methods Fifty-three patients with chronic pulmonary heart disease in the aggravation period were accepted emergencyward in the Guangzhou Red Cross Hospital during June 2007 to May 2008,they were randomly divided into the treatment group (28 case) and control group (25 case) . Both groups were given low flux breathe in oxygen and dissipate phlegm and relieve a cough and resist infection and spasmo]ysis and calm down asthma and strive heart and diuresis colligate therapy. Mean while,patients in the treatment group,beside the colligate therapy,were treated with prostaglandin E1 10 ml and magnesium sulfate 10 ml ,the course of treatment lasted 2 weeks. Then we investigate the amelioration of clinical symptom and alteration of blood gas analysis in the two groups before and after the treatment. Results The rate of clinical efficacy were 89.3% (25/28) and 76.0% (18/25),with superiority in the treatment group (χ2=1.87,P<0.05) . Whole blood viscosity,fibrinogen,PaO2 and PaCO2 were improved in both groups,amelioration of blood gas analysis observation superiority in the treatment group compared with control group (P<0.05). Conclu-sions Prostaglandin E1 and magnesium sulfate can depress pulmonary artery pressure and abate the afterload of right ventricle,which have better treatment effect in chronic pulmonary heart disease in the aggravation period.     

Combined therapy for migraine prevention? Clinical experience with a beta-blocker plus sodium valproate in 52 resistant migraine patients

The aim was to explore whether combining a beta-blocker and sodium valproate could lead to an advantage in efficacy in patients with migraine previously resistant to the two medications in monotherapy. Fifty-two patients (43 women) with a history of episodic migraine with or without aura, and previously unresponsive to beta-blockers and sodium valproate in monotherapy, were treated with a combination of propranolol or nadolol and sodium valproate in an open-label fashion. Eight patients (15%) discontinued due to adverse events. Fifteen (29%) did not respond. The remaining 29 cases (56%) showed response (> 50% reduction in migraine days). The response was excellent in nine (17%). From this open trial, combination therapy with a beta-blocker and sodium valproate appears to be a good migraine preventative in some previously resistant migraine cases. Controlled trials are now necessary to determine the true advantage in efficacy of this combination in difficult to treat migraineurs.

丙戊酸钠改善精神分裂症患者认知功能障碍的对照研究

目的 探讨丙戊酸钠改善精神分裂症患者认知功能障碍的疗效.方法 将80例精神分裂症患者随机分成研究组(40例)和对照组(40例),研究组患者使用新型抗精神病药合并丙戊酸钠系统治疗,对照组患者单用新型抗精神病药物系统治疗,共治疗8周.全部病例在治疗前后分别进行阳性和阴性综合征量表(PANSS)、韦氏成人智力量表(WAIS-RC)、韦氏记忆量表(WMS)、威斯康星卡片分类测验(WCST)进行疗效评定,应用治疗中需处理的不良反应症状量表(TESS)评定不良反应.结果 与基线时比较,两组在治疗后第4、8周末PANSS总分及各因子分均有明显降低(P＜0.05),研究组治疗后第8周末PANSS总分及各因子分均显著低于对照组(P＜0.05).治疗后第8周末,两组WMS、WAIS-RC、WCST评分与基线时比较,除即刻记忆评分外其余各项评分差异均有统计学意义(P＜0.05),两组间比较,除即刻记忆评分外其余各项评分均有显著性差异(P ＜0.05,P＜0.01).结论 丙戊酸钠对精神分裂症患者的认知功能障碍有明显改善效果.     

School-age human figure drawings by very preterm infants: Validity of the Draw-a-Man test to detect behavioral and cognitive disorders

Detecting an abnormal developmental trajectory in very preterm infants remains challenging. The objective of this study was to determine the correlation between the Draw-a-Man test (DAMT) and behavioral and cognitive disabilities in very preterm infants. From the school-age follow-up of the Premag study, which evaluated the neuroprotective effect of prenatal magnesium sulfate before 33 weeks of gestation, 281 human figure drawings were assessed (mean age, 11 years). Behavioral and cognitive disabilities were associated with delayed DAMTs but test performance indicators were insufficient to use DAMT as a screening or a diagnostic test.     

Efeitos de tramadol,magnésio e cetamina por via intra‐articular sobre a dor pós‐operatória em meniscectomia artroscópica

Objective

Postoperative pain control is important in terms of early recovery and rehabilitation in arthroscopic meniscectomy. For this purpose, we aimed to compare the effects of intraarticular tramadol, magnesium, and ketamine with combinations of pericapsular bupivacaine on postoperative pain and recovery in arthroscopic meniscectomy.

硫酸镁注射液治疗婴幼儿喘息性疾病的分析

调查分析我院门诊、急诊患儿硫酸镁注射液的应用情况，为临床合理用药和儿科安全用药提供参考依据。对2017年11月门急诊含硫酸镁电子处方进行回顾性分析，内容包括年龄、用法用量、临床诊断、联合用药，使用天数等。共计204例患儿使用硫酸镁注射液，年龄在6个月至1岁之间的患儿最多，共72例，占比35.29%。67.65%的患儿使用剂量是30~50 mg·kg-1·d-1。临床诊断分别为急性喘息性支气管炎（32.35%）、肺炎（29.41%）、支气管炎（23.53%）等。在治疗方案中，硫酸镁常和糖皮质激素合用，其中有58.82%和醋酸甲泼尼龙合用，55.88%和布地奈德合用。目前硫酸镁在婴幼儿喘息性疾病的应用尚无统一、权威标准，可能存在用药风险。临床用药应加以重视、规范管理，保证用药安全。本研究结果对儿科合理使用硫酸镁注射液有参考价值。     

Potassium,Magnesium, and Electrolyte Imbalance and Complications in Disease Management

Electrolyte balance is a critical issue in managing comorbid conditions in both diseased and elderly patients. Patients with hypertension and diabetes need careful regulation of their calcium and magnesium levels, whereas in patients with congestive heart failure, sodium and potassium levels also are critical. Herein we report the outcome of a round table discussion at which issues of renal magnesium clearance, magnesium and arrhythmic risk, ion balance in heart failure, diabetes, ischemic stress, oxidative stress in the cardiomyopathy of magnesium deficiency, roles of magnesium and potassium in bone metabolism and the aging population, and the role of electrolyte balance in hypertension have been discussed. In all these issues the maintaining homeostasis of potassium and magnesium is critical and the various therapies that impact on retaining these ions were discussed. Hallmark studies, i.e., Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial and Studies of Left Ventricular Dysfunction, have provided insight into treatment of patients with cardiovascular and progressive heart failure. These studies and the availability of potassium- and magnesium-sparing diuretics for use in these disorders provide relevant perspectives for treatment.     

SLC41A1 is the only magnesium responsive gene significantly overexpressed in placentas of preeclamptic women

Objective: To examine expression profile of magnesium responsive genes (MRGs) in placentas of normoevolutive and preeclamptic women. Methods: The expression profiles of MRGs were determined in placentas of normoevolutive (N?=?26) and preeclamptic (N?=?25) women by RT-qPCR. Results: Among all tested MRGs (9) only SLC41A1 (encoding for Na⁺/Mg²⁺ exchanger) was significantly overexpressed in ～54.2% of preeclamptic (n?=?24) and in ～9.5% of normoevolutive (n?=?21) specimens. On average, SLC41A1 was overexpressed sixfold in the preeclamptic group. Presence of SLC41A1 in placentas was confirmed by Western blot analysis. Conclusion. SLC41A1 is significantly overexpressed in nearly 55% of preeclamptic placentas. This may indicate a direct contribution of changed Mg homeostasis in the development of preeclampsia.
