尽管人们普遍同意血清胆固醇升高和高血压二者均和冠心病发病密切相关,但是目前内科医生们认为,针对血胆固醇的预防措施在预防心脏病方面的作用比针对高血压的作用来得小.1971年到1980年接受内科治疗的高血压病人从36%增加到56%,而且血压得到满意控制的从16%增加到34%.流行病学研究揭示高血压是冠心病的一个易患因素,临床资料也表明,治疗高血压对预防冠心病有效.因而制定了防治政策,提出了有关筛选标准,以及那些病人需要治疗以及如何

世界核心医学期刊文摘（妇产科学分册） 2006年第11期2卷 58-59页

作者： Pocock s.b. 柳蕴

ObJECTIVE: To evaluate infective endocarditis prophylaxis practices during the intrapartum period and to assess obstetric providers’ adherence to the American Heart Association and American College of Obstetrics and Gynecology guidelines for infective endocarditis prophylaxis. METHODs: We performed a chart review of pharmacy, electronic nursing, and physician records to report this case series of obstetric patients who received infective endocarditis prophylaxis during the intrapartum period at a single tertiary referral care center during a 1-year study period from August 1, 2004, to July 31, 2005. REsULTs: Fifty patients received antibiotics for infective endocarditis prophylaxis. Three of the 50 patients who received infective endocarditis prophylaxis had high-risk cardiac lesions and three other patients had moderate-risk cardiac lesions and evidence for intrapartum infection. Thus, only six patients (12.0% , 95% confidence interval 4.5% - 24.3% )met the American Heart Association and American College of Obstetricians and Gynecologists criteria for an appropriate indication for infective endocarditis prophylaxis. Of these six patients who had an appropriate indication for infective endocarditis prophylaxis, only three (50.0% , 95% confidence interval 11.8% - 88.2% ) received appropriate antibiotic regimens. CONCLUsION: Antibiotics are frequently given to obstetric patients during pregnancy. Although many obstetric patients receive antibiotics for recommended indications, some patients, as our study shows, do not. A concerted effort by all practitioners and institutions to reduce the amount of inappropriate antibiotics given to obstetric patients will have positive public health effects in addition to benefiting individual mothers and neonates.

We have synthesized mannich base cyclohexanone using microwave irradiation method,and studied their pharma-cological *** on analytical and spectral(IR,NMR and Mass) data,a number of mono as well as double mannich base cyclohexanones have been synthesized from primary and secondary amines and formaldehyde,and then purified and characterized. The required 3-aryl-2,4-diacetyl-5-hydroxy-5-methylcyclohexanone was prepared from appropriate aldehyde and acetylacetone. The synthesized compounds were screened for analgesic activity via standard approaches,and they have shown positive analgesic activity.

肉用仔鸡的屠宰

作为家禽屠宰方法的制订依据的某些研究结果是错误的。因此用目前使用电击器的方法,只有约三分之一肉用仔鸡是被电击器击的;其他不是当场被击毙。就是未充分被击晕的。虽然死鸡在静脉切开后最初90秒钟内比电击晕的鸡放血稍慢,但在180秒后两组的放血量是没有差别。留存在胴体内的血液量的差别并不造成胴体有可察觉的差别,留存在胴体的血液量也不会影响胴体的保存质量。业已提出,胴体放血量和胴体质量之间的这种不相关性,可能是由于肌肉毛细血管床没有失去任何血液——所有自颈部流出的血液都来自内脏和大血管。这些研究结果表明,所有的家禽都应当用电击器击毙,从而防止与目前的屠宰方法联系在一起的残忍。为此。应将电击器的电压调节到能保证至少有120毫安电流通过每一只鸡的水平。一般调到200伏即可。但是电击器刻度盘常常会严重夸大实际通过电击器的电压,所以应当由电工来测量运行中的电击器的实际电压和电流(可能比空转的电击器的电压和电流的一半还低)。
