Extracts of Monascusus Purpureus beyond Statins——Profile of Efficacy and Safety of the Use of Extracts of Monascus Purpureus

Monascus purpureus is a fungus that has been tradi-tionally used in China for thousands of years to produce ricewine . Traditionally the fungus is used to ferment non-gluti-nous cooking of rice ,to produce a kind of famous red ricewine .Its main traditional indications consist of disordersdue to the accumulation of fats (nosologically linked withthe problems of stasis of circulation in traditional Chinesemedicine) ,liver disorders and some forms of tumor as ithelps i mprove the circulation of …     

Sexual precocity: sex incidence and aetiology

The aetiology of 197 girls and 16 boys presenting with sexual precocity was reviewed. Ninety one girls and four boys had central precocious puberty (M:F 23:1); a cause was identified in all the boys but in only six girls. All boys with precocious puberty need detailed investigation; in girls investigation should be based on clinical findings, particularly the consonance of puberty.     

显微注射后家兔转基因受精卵的体外培养和移植成活率的观察研究

目的：研究家兔受精卵经显微注射转基因过程的耐受性，建立转基因动物技术平台。方法：(1)家兔超数排卵诱导；(2)对2000个家兔受精卵进行显微注射技术操作；(3)对1280个受精卵进行显微注射后体外培养观察；(4)216个注射后受精卵向13只受体母兔输卵管进行移植．结果：(1)经显微注射后受精卵进行体外培养有68％的受精卵能够发育至桑椹胚和囊胚；(2)目前有7只受体母兔经输卵管转基因受精卵移植分别产下3，4，5，2，6，13，7只仔兔。结论：(1)受精卵能够在体外经受显微注射转基因过程的损伤，但暴露于体外的操作时间应尽可能的缩短；(2)显微注射操作技术的熟练程度是实验成功的关键。     

同种异体原位心脏移植术后心电图分析

目的：探讨同种异体原位心脏移植术后患者的心电图改变特点，方法：对3例心脏移植的患者术后分别进行体表12导联心电图跟踪观察，主要观察心率、心律、ST-T演变情况，结果：共同表现的ST段抬高系心肌再灌注后损伤性改变，不完全性右束支传导阻滞与手术中机械刺激或损伤有关，由于去神经作用心率变化较小，应用标准术式患者易出现心律失常，应用双腔静脉原位心脏移植术后心律失常发生率较少，结论：心脏移植术前、术后心电图追踪观察有助于指导治疗和评估预后。     

Low calorie commercial sugar is a sensitive marker of glomerular filtration rate

BACKGROUND: Glomerular filtration rate (GFR) in humans and animals might be determined with precision by measuring the clearance of an ideal marker, such as inulin. However, the use of inutest, an inulin analog, is limited by its cost and accessibility. The present study tested whether low calorie commercial sugar (LC sugar) can be used to measure GFR during normal and renal dysfunction. METHODS: Two groups of 6 male Wistar rats weighing 300 to 350 g were included. One group was treated with a daily dose of cyclosporine (CsA) 30 mg/kg subcutaneously for 7 days and the other group was formed by nontreated control rats. In one half of each group, GFR was evaluated by using inutest and in the other half by using LC sugar. GFR was also evaluated by using a wide LC sugar plasma concentration range in an additional group. RESULTS: In nontreated rats, the mean GFR evaluated with LC sugar was 2.2 +/- 0.1 mL/min. This value is equal to that obtained with inutest: 2.3 +/- 0.1 mL/min. CsA administration produced a significant reduction of renal blood flow and renal function. The GFR reduction induced by CsA was similarly determined by both LC sugar and inutest to be at 1.0 +/- 0.2 and 1.1 +/- 0.2 mL/min (P= NS), respectively. In addition, GFR did not change when LC sugar plasma concentration gradually increased. CONCLUSION: Our results show that in both normal and pathophysiologic conditions, LC sugar is a good marker of GFR similar to the gold standard inutest.     

Better Living Through Chemistry: Does It Still Apply to Patients After Myocardial Infarction?

Sudden cardiac death is an elusive process that claims a significant number of lives annually in the United States. It is often associated with increased mortality within the first year after myocardial infarction, with the highest frequency occurring among patients with left ventricular dysfunction. Therefore, increasing survival rates in patients with a history of both disorders is an important goal of therapy. Recent trials suggested that an implantable cardioverter-defibrillator (ICD) in these patients may be superior to medical intervention in reducing the high mortality rate. Four major trials measured the benefits of an ICD for patients at risk for life-threatening ventricular arrhythmias. We assessed whether patients in these trials received adequate drug therapy as directed by American College of Cardiology-American Heart Association guidelines. One aim was to determine if medicated patients who served as controls in the trials were fairly represented. Furthermore, the need for improved overall guideline adherence was apparent.     

尿微量蛋白与老年2型糖尿病合并缺血性心脏病关系的研究

目的探讨在老年2型糖尿病合并缺血性心脏病患者中尿微量蛋白在加重缺血性心脏病进展方面的作用。方法将66例老年2型糖尿病合并缺血性心脏病患者按24h尿微量蛋白排泄量分为:尿微量蛋白正常组及尿微量蛋白阳性组,分别对血脂、空腹血糖、血清胰岛素、胰岛素敏感指数、纤维蛋白原、颈动脉内-中膜厚度、颈总动脉粥样硬化等级积分、硬化斑块指数、心脏彩超室间隔厚度及射血分数等加重缺血性心脏病进展等指标进行比较分析。结果66例老年2型糖尿病合并缺血性心脏病患者尿微量蛋白阳性组高密度脂蛋白、载脂蛋白A、胰岛素敏感指数、年龄、纤维蛋白原、硬化斑块指数、颈总动脉粥样硬化等级积分、室间隔厚度及射血分数显著高于尿微量蛋白阴性组(P<0.05,P<0.01)。结论尿微量蛋白的出现能够加速糖尿病合并缺血性心脏病的发展进程,它的出现预示着缺血性心脏病的预后不良。
