23、potlight, but common fears are unfounded, says epidemiologist Rory Collins. Millions of people take statins (他汀类药物) to lower cholesterol. So there was (26) interest when two articles appeared in The BMJ, a leading British medical journal, last year (27) their safety.This week the journal admitted bo
24、th had overstated the extent of (28) in some patients. That part of both papers has now been corrected. But some researchers are worried that coverage has caused (29) and will put some people off taking these drugs. So what are the facts about statins? Jon White spoke to epidemiologist Rory Collins.
25、 What are statins? They are a group of drugs that lower the risk of cardiovascular events such as (30) and ischaemic strokesstrokes due to clots in the arteries to the brainand the need for (31) such as a heart bypass. The short name is “statin“ because all the drug names end in it. Simvastatin and
26、atorvastatin are two (32) available ones.They stop a liver enzyme (酶) which (33) making cholesterol; blocking it reduces (34) cholesterol made in the liver. In response to that, liver cells put more (35) for a form of cholesterol known as LDLsometimes called bad cholesterolon their surface. Those re
27、ceptors pull more LDL out of the blood, so lowering levels. That LDL cholesterol is metabolised by the liver and excreted.（分数：71.00）填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_九、Part Reading Compr(总题数：0，分数：0.00)十、Section A(总题数：1，分数：35.50)Basic health interventions may signi

If
34、 you have high blood pressure, youre in good company. Hypertension (高血压) afflicts 67 million Americans, including nearly two-thirds of people over age 60. But it isnt an inevitable part of the aging process. Its better to think of it as chronic sodium intoxication (钠中毒). And, as an important new stu
35、dy from Britain shows, theres a way to prevent the problemand to save many, many lives.B. A lifetime of consuming too much sodiummostly in the form of sodium chloride (氯化钠), or table saltraises blood pressure, and high blood pressure kills and disables people by triggering strokes and heart attacks.
36、 In the United States, according to best estimates, excess sodium is killing between 40,000 and 90,000 people and running up to $20 billion in medical costs a year.C. Americans on average take in about 3,300 milligrams of sodium per day, but experts recommend less than 2,300 milligramsand less than
37、1,500 milligrams for people over age 50, black people, or those who already have hypertension, diabetes (糖尿病) or kidney (肾脏) disease, which adds up to a majority of American adults. Either target is far below where most Americans are now.D. The reason that nearly everyone eats too much sodium is tha
38、t our food is loaded with it, and often where we dont taste or expect it. Of course ham and canned soup are full of salt, but so are many foods that are surprising: A blueberry muffin (松饼) can have more than double the salt of a serving of potato chips. Even healthy-sounding food can pack heavy sodi
39、um loads. Two slices of whole wheat bread can have nearly 400 milligrams of sodium, as can two tablespoons of fat-free salad dressing. Eight ounces of V8 vegetable juice contains well over 500 milligrams. Many restaurant entrees (主菜) have far more sodium than is recommended for an entire day. Appleb
40、ees lemon shrimp fettuccine (意大利宽面条), at 5,100 milligrams, has more than twice as much.E. Doctors warn people with high blood pressure to go on a low-salt diet, but thats virtually impossible in todays world, because nearly 80 percent of the sodium that Americans eat comes in packaged and restaurant
41、 food (whether its a bagel, a sandwich or a steak dinner). You cant take it out. And nearly everyone, not just people with hypertension puzzling over food labels, should be taking in less sodium. The only way to prevent millions of Americans from developing high blood pressure is for companies and r
42、estaurants to stop loading up their food with sodium.F. Health experts have been asking the food industry to do that for decades. Its not easy, but it isnt impossible either. Sure, we all like the taste of salt, but there is much that food companies can do without driving away customers. Often they
43、add sodium for leavening (发酵) or food texture (质地) rather than taste, when replacement ingredients are available. And sodium levels in similar popular foods made by different manufacturers often vary two- or threefold (for example, a slice of pizza can pack anywhere from between 370 and 730 milligra
44、ms), which suggests that many manufacturers Can cut sodium levels in their foods sharply without hurting taste. When salt levels in food drop, peoples preference for salt also shifts down, so no one would notice a gradual reduction in sodium across all foods.G. Thats exactly what Britains Food Stand
45、ards Agency has done. It divided processed food into different categories, set salt-reduction targets in each category and then asked companies to meet those targets over time. And as these companies did that, from 2001 to 2011, sodium consumption by the British fell 15 percent. The new study shows
46、that this drop in salt intake has been accompanied by a substantial reduction in average blood pressure, a 40 percent drop in deaths from heart attacks and a 42 percent decline in deaths from stroke.H. A few scientific critics have been arguing for years that reducing salt intake is risky because it
47、 might increase mortality in some people receiving aggressive treatment for congestive heart failure, but the British data show at a national level what smaller studies projectthat when sodium levels in everyones food drop, so does the number of people dying from heart disease and stroke.I. Lower sm
48、oking rates in Britain no doubt are helping as well, but as the authors of the study point out, the fall in mortality echoes the success of Japan and Finland in earlier decades, both of which reduced sodium consumption from sky-high levels with focused government efforts and saw huge drops in heart attacks and strokes.J. Here in the United States, in 2010, an Institute of Medicine panel was so troubled by salt-caused deaths
