简述亚急性联合变性的预后。

答案

参考答案:

亚急性联合变性的预后:(1)神经症状一般在补充维生素B治疗后8~14天开始改善,可能在6个月后缓慢恢复,并且与病情程度和病程相关。(2)维生素B治疗可使病情发展停止。SCD若能在3个月内早发现、早治疗,预后良好并可望完全恢复,病变较重者可能遗留不同程度的神经功能缺损,如不治疗2~3年后可逐渐加重,甚至死亡。(3)SCD是一种可治疗性疾病,预后较好。早期诊断、早期治疗是决定本病预后的关键。

With the holidays coming up, lots of people will be having parties. Want to make sure you’re a perfect host or guest(客人)? Now it’s a good time to brush up on your party manners.

When inviting guests to your party,  send invitations to their homes instead of passing them out at school. This way, you won’t hurt the feeling of classmates you didn’t invite.

<83>Wait for all your guests to arrive before starting any activities. If people at the party don’t know each other, make sure you introduce everyone.

If your guests bring gifts for you, thank each gift----giver as you open his/her present. After the party, be sure to send a hand-written thank-you card to each guest, telling them how much you appreciate their gifts.

When you receive a invitation to a party, be sure to let the host know whether you can come.

Arrive on time. Bring a gift to a birthday party. <84>If it’s a holiday party, ask the host if there’s anything you can bring. Adults often bring a desert or a bottle of wine to a party, even when the host tells them that he/she doesn’t need anything. Young people don’t have to do this, but it’s always polite to ask.

Be friendly to the other guests. Remember to say “Please” and “Thank you”! When you leave, thank the host for the party.
