诊断库欣综合征最有意义的检查是()

A.AcrrH兴奋性试验

B.甲吡酮试验

C.赛庚啶试验

D.地塞米松抑制试验

E.螺内酯试验

答案

参考答案:D

解析:促肾上腺皮质激素试验(简称ACTH试验):ACTH刺激肾上腺皮质分泌激素,可反映皮质贮备功能,本试验可用以鉴别原发性或继发性肾上腺皮质机能低下。甲吡酮试验:甲吡酮抑制11β-羟化酶而使11-去氧皮质酮转变为皮质酮及11-去氧皮质醇转变成皮质醇的过程受阻,使血浆皮质醇降低,从而反馈抑制减弱,促使垂体分泌大量ACTH,此试验可测定垂体分泌ACTH的储备能力。地塞米松抑制试验:给予地塞米松可反馈抑制垂体分泌ACTH。本法用于测定皮质醇增多症原因。螺内酯试验:螺内酯可拮抗醛固酮,使醛固酮增多症病人电解质紊乱得到纠正,血压常有不同程度的下降,有助本症诊断,但不能鉴别原发或继发性醛固酮增多症。赛庚啶试验:血清素具有兴奋醛固酮分泌作用,可能为特醛症发病因素之一。赛庚啶为血清素拮抗剂。此试验可用来鉴别特发性醛固酮增多症还是醛固酮瘤。

     The story of Madame Tussaud is as fascinating as that of the exhibition itself. From a housekeeper's

daughter to a successful business woman, her life has all the marks of a Hollywood blockbuster.

     Madam Tussaud was born in 1761 and named Marie Grosholtz. Her father was killed in battle only two

months before Mane's birth. For the first five years of her life, Marie lived in Berne with her mother, who

worked as housekeeper for Dr Philippe Curtius. A doctor, with a talent for wax modeling, Curtius became

her teacher.

     It was Curtius who opened the original wax exhibition in Paris in 1770 and introduced Marie to some

famous people. At only 17, she modeled the famous writer Francois Voltaire, followed by a portrait of

American statesman Benjamin Franklin when he was in Paris as US ambassador. Both figures are still on

display at Madame Tussaud's, London today.

     Her work at Curtius successful wax exhibition led to an invitation to the court of Louis XVI and his

queen. For nine years she lived at the palace of Versailles guiding the artistic education of the king's sister.

Meanwhile the French Revolution was about to erupt. Aware of the political arrest, Philippe Curtius called

Marie back to Paris. Marie's connection with the royal family made her guilty. Both she and her mother

were arrested. After she was set free, Marie was forced to make death masks (a death mask is a model of

a dead person's face, made by coving their face with a soft substance and letting it become hard) of executed

(被处决的) nobles. Many were former friends at court, including her former employers, the king and queen.

     By 1800 Marie was married with two young children and a poor business inherited from Curtius. Madame

Tussaud made the decision to take her exhibition on tour. In 1802, she left France. For the next 33 years,

Madame Tussaud traveled the British Isles, exhibiting her growing collection of portraits. In those pre-television

days, this was the only way most people had direct contact with the famous people of the time. The exhibition

became permanently based in London in 1835, moving to its present site in Marylebone Road in 1884. Her last

work, a remarkable self-portrait that is still on show, was completed only eight years before her death aged 89.
