单选题Have you ever been startled by a loud noise or by someone appearing suddenly behind you on dark night or by a snake in the grass? Do you remember the sudden, tight feeling in your chest, the way your heart started go pound, the way you seemed to breathe more rapidly? Such reactions occurred because you were frightened. Your brain sent a signal to the special gland (腺) in your body caned the adrenal (肾上的) gland. Other parts of your body were involved, too, but the adrenal gland has a very special function. The adrenal gland is located on top of your kidney. Since you have two kidneys. You also have two adrenal glands. Each adrenal gland is divided into two parts: a cortex (外皮) and a medulla (髓质). The cortex forms the outer shell; the medulla forms the central core. Both the cortex and the medulla secrete (分泌) hormones, but they have different functions. The cortex produces more than forty different chemical compounds and hormones. All these things are essential to sustain life. The medulla secretes adrenalin (also called epinephrine, the hormone that prepares the body for emergencies.) When you are suddenly faced with a dangerous or stressful situation, part of your brain instantly sends a signal to the adrenal gland, and all sorts of things begin to your body. The medulla releases an extra amount of adrenalin into the bloodstream. The adrenalin is carried rapidly throughout the body, stimulating other glands and systems.

单选题 Studies have hinted that breast cancer survivors tend to gain weight after their diagnosis and treatment, but it's not yet clear why. Because breast cancer rates tend to rise around menopause (更年期), doctors weren't sure whether the weight gain was part of normal aging and changes in women's reproductive status, or whether something about cancer made patients more vulnerable to gaining weight. In a new study published in Cancer Epidemiology, Biomarkers Prevention, researchers compared a group of women who survived breast cancer with a similar group of women who did not have the disease. All women were at higher risk of developing breast cancer because of family history. The scientists found that even after they adjusted for the influence of age, menopause and other factors, those who survived breast cancer did indeed gain more weight— almost four pounds more, on average, within five years of their diagnosis compared to those who didn't have cancer. Among these women, those who were treated with chemotherapy (化疗) were twice as likely to gain weight—about 11 pounds more, on average—compared to women who were treated with hormone-based therapies (who did not get any heavier with their treatments) and women who didn't have cancer. While weight has been implicated in possibly playing some role in certain cancers, this study is among the first to tease apart what effect cancer itself, and treatments for cancer, might have on changing metabolism, inflammation, the immune system and other body functions to make weight gain more likely. By following the women for four years, the researchers, led by Dr. Kala Visvanathan, director of clinical cancer genetics and prevention service at the Johns Hopkins Kimmel Cancer Center, compared their weight changes from diagnosis onward. The team is planning to continue to follow the women for a longer period of time to track other patterns in weight. 'Obviously treatment for the cancer is a priority,' says Visvanathan. 'But these findings show that it's also important to take note of weight changes, especially for women getting chemotherapy. Chemotherapy treatment usually goes for six months or a year, so monitoring weight in that time and taking steps to intervene if weight is clearly increasing is important.'
