C.高胰岛素血症

E.多毛、痤疮等高雄激素血症的临床表现
参考答案：C
解析：PCOS诊断依据临床症状、血清激亲水平及B超检查综合判断，但目前对PCOS的诊断标准尚不统一。主要诊断标准是：①稀发排卵或无排卵；②高雄激素血症或高雄激素的临床表现，如多毛、痤疮等；③超声检查在月经周期或黄体酮撤退后出血的3～5日进行，显示一侧卵巢均有≥10个且直径2～9mm的小卵泡，即卵巢多囊样改变，和（或）卵巢体积增大。

| One day the bathroom door had slammed on Timmy's finger. The doctor asked if we had found the tip of Timmy's finger. He said there was a small chance of 1 it if we could get it to him quickly. Pulling myself out of a daze, I ran back to the bathroom. 2 , it had already turned blue. I knew from the look on the doctor's face that it was too late. I felt helpless, unable to take the pain away from my little boy. Then a(n) 3 came to me. I whispered in his ear, "Timmy, did you know that lizards grow their tails 4 and little boys can grow their fingers back too?" Timmy's soft green eyes grew wide with 5 ,"They can?" he asked, obviously surprised by the thought,"And 6 ?" I told him, "Inside your head you have a little voice telling your finger how much you love it and how much you 7 it." I could see Timmy's little face focused in deep concentration. Then I continued, "Now just say, grow for me finger, grow. I love you and I need you."A few days later, Timmy said to me quietly, "I'm talking to my finger every day, 8 it well." Weeks later, with a joyful burst of 9 , Timmy ran towards me. "See," he said, "It's growing back really good!" A year later, Timmy's finger grew back and became well again just as any finger 10 be. Timmy remains forever in my heart as a constant reminder of the 11 of miracles. He also inspires me to 12 beyond the accepted knowledge of the times, and to remember that all things are possible if you truly believe. | ||||
