A 57-year-old man with long-standing diabetes mellitus and newly diagnosed hypertension presents to his primary care physician for follow-up. The patient has been trying to alter his dietary habits and now exercises more frequently, but the hypertension has persisted. The patient is started on an angiotensinconverting enzyme inhibitor (ACE inhibitor) with good results. He is instructed to continue this medication and follow up in several months. Questions: 1. What are the effects of angiotensin II? 2. How would inhibition of ACE decrease blood pressure?

【简答题】Case file study（You can answer the question either in Chinese or English) A 68-year-old female in a hypertensive crisis is being treated in the intensive care unit (ICU) with intravenous nitroprusside for 48 hours. The patient’s blood pressure was brought back down to normal levels; however, she was complaining of a burning sensation in her throat and mouth followed by nausea and vomiting, diaphoresis, agitation, and dyspnea. The nurse noticed a sweet almond smell in her breath. An arterial blood gas revealed a significant metabolic acidosis. A serum test suggests a metabolite of nitroprusside, thiocyanate, is at toxic levels. 1.What is the likely cause of her symptoms? 2.What is the biochemical mechanism of this problem? 3.What is the treatment for this condition?

高血压性脑病(hypertensive encephlopathy)(名词解释)

Many millions of people have high blood pressure(hypertension 高血压). What's so frightening about this so called silent killer is that it often does not produce (51) for years, secretly damaging arteries and organs throughout the body until it erupts (爆发) in the form. of stroke, heart attack, congestive heart failure(充血性尽力衰竭) or kidney disease. (52) left untreated, even mild hypertension can reduce the life expectancy of a 35-year-old (53) several years. (Readings of 140 to 159 over 90 to 99 are mildly high; about 120/80 is normal. )

That's why high blood pressure is commonly treated with anti-hypertensive drugs. But studies (54) that in some people an increase in calcium(钙) consumption can help (55) blood pressure without medication(药物治疗)。

Calcium also seems to help prevent high blood pressure. (56) the results of 13-year survey (57) by the U.S. National Center for Health Statistics, James H. Dwyer, associate professor of (58) medicine at the University of Southern California School of Medicine, found that people who consumed 1300 milligrams of calcium a day were 12 percent (59) likely to develop hypertension than those (60) only 300 mg. a day. In people under age 40, risk was reduced by up to 25 percent.

Soon doctors may (61) some hypertension patients to increase their calcium intake, (62) the way they now advise sodium(钠) restriction. "It's (63) to add food or supplements than to go on a low-sodium diet," (64) Dr. David McCarron, professor of medicine at Oregon Health Sciences University. "Our studies show that people who try the low-sodium (65) don't stay with it very long. "
