B.限制活动和石膏固定

C.体疗加内服药物

D.伤湿止痛膏局部贴敷

答案

参考答案:E

解析:根据典型的临床表现即可诊断。狭窄性腱鞘炎也是一种慢性损伤性炎症,与手指长期快速用力活动有关,好发于手的屈指肌腱鞘和腕部拇长展肌和拇短伸肌的腱鞘,后者称为桡骨茎突狭窄性腱鞘炎。疗效较好的治疗方法是腱鞘内醋酸强的松龙注射,注射一定要准确。局部制动也有一定疗效。如非手术治疗无效,可考虑行狭窄腱鞘切除术。

Five million people visit Grand Canyon in the US every year. For the purpose of helping project Grand Canyon for your fellow visitors and future generations, please follow the guidelines below.

To project the park, camping is allowed only within permitted campgrounds. Permits are required for overnight camping at the North Rim. Advance booking can be received by mail. Please write: Information Center, P.O. Box 129, Grand Canyon, AZ 86023

Fires

Because of the extreme fire danger, campfires are not allowed except at Mather and Desert View campgrounds. Collection of firewood is not allowed either.

Please stay on permitted paths. Otherwise you may destroy desert plants. Pack out what you pack in, so you leave no signs of your visit. It is important to keep in mind that you are in a national park where wildlife exists.

Wildlife

Hungry deer can be danger and have kicked and bitten visitors at Grand Canyon. Some other animals will also beg and bite. For your own safety and the well-being of the animals, please do not feed wildlife, no matter how gentle they may appear.
