问题 单项选择题

新生儿尤其是早产儿易发生寒冷伤综合征的病理生理中,错误的是()。

A.体温调节中枢发育不成熟

B.皮肤表面积相对较大

C.血流较丰富

D.棕色脂肪含量较多

E.体内能量储存少

答案

参考答案:D

解析:新生儿体温调节与皮下脂肪组成特点:新生儿因体温调节中枢发育不成熟,造成其体温调节功能不足;新生儿皮肤表面积相对较大,血流丰富,易于失热;体内能量贮存少,产热不足;产热方式又以棕色脂肪组织的化学产热为主,缺乏寒战等物理产热方式;因此,新生儿,尤以早产儿、低出生体重儿和小于胎龄儿更易发生低体温。新生儿皮下脂肪组织的含量以熔点高的饱和脂肪酸多于不饱和脂肪酸,当受到寒冷或各种原因引起体温下降时,皮脂容易发生硬化,出现硬肿症。

Cambodians are continuing to mourn the death of King-Father Norodom Sihanouk, who died in Beijing this week. In an exclusive interview with CCTV, China’s ambassador to Cambodia, Pan Guangxue, says Sihanouk made indelible(不可磨灭的) contributions to Sino-Cambodian relations and his death will not affect the friendship between the two countries.

Since its founding, the People’s Republic of China has maintained close contact with Cambodia. Bilateral(双边的) trade volume has increased rapidly in recent years, from 200 million US dollars in 2002 to nearly 2.5 billion US dollars in 2011.

China is now not only Cambodia’s third largest trading partner, but for many years has been Cambodia’s number one investor. Norodom Sihanouk, Cambodia’s “King-Father” pioneered the relationship.

Pan Guangxue said, “If we look back at previous decades, I think Sihanouk made the right choice, a choice good to Cambodian national development. It was because of his commitment to the development of Sino-Cambodia friendship that we’ve achieved what we have today.”

In 2010, the two countries established a comprehensive strategic partnership, during its Prime Minister Hun Sen’s visit to China.

And 2013 is set to be China-Cambodia Friendship Year.

Pan Guangxue said, “Cambodian Prime Minister Hun Sen said on many occasions that China does not tell Cambodia what to do or what not to do. China does not point fingers at Cambodia. I think this is a true evaluation of Sino-Cambodian relations. China pursues an independent peaceful foreign policy of non-alignment(不结盟) and non-interference in the internal affairs of other countries.”

The ambassador says Sihanouk’s death is a huge loss to both China and Cambodia, but that bilateral relations will not be affected.

Pan Guangxue said, “I believe the bilateral relationship will be sustained and grow even stronger.”

With both countries enjoying the benefits of the fruitful relationship, the governments of China and Cambodia have promised that Sihanouk’s legacy(遗产) will continue to be the foundation of even stronger ties.
