“Please help me find the Rh AB negative blood(熊猫血) for my father!” Miss Huang from Wuhan asked for help on Changjiang Daily on July 21, 2019. Her father was over 70 and he was in a serious situation when she took him to a hospital. He needed an immediate operation(手术), or he could lose his life. However, there was no Rh AB negative blood for him. The doctors had to put off the operation.

“An old man with Rh AB negative blood is in great danger. We need such blood for his operation!” Shen Jian who works in the Wuhan Blood Center called out the volunteers in their public QQ groups. He checked their information on the computer and called them one by one. Yu Zhou was doing housework when he received Shen’s call at nine o’clock at night. He went to the center and donated(捐) 400 ml of blood at once. Wang Bing was at work when he picked up the phone. As soon as he finished working, he went to donate 400 ml of blood as well. Xu Huijun donated 200 ml. Tan Peng and Lu Juanzhi also donated their blood in the closest blood center.

By July 22, the five volunteers donated 1,600 ml of Rh AB negative blood after passing examinations. The doctor had an operation on the old man soon.

Just three percent of people own(拥有) Rh AB negative blood. Wuhan Blood Center set up three QQ groups for volunteers in 2002. They give their blood regularly(定期地) and have helped people in trouble for years.

“Amy! Milk!” Mama called.

Milk. It was Amy’s turn to get it. Amy sighed and shut her first-aid(急救) book.

Amy tied the cow close to a tree. Somewhere down the mountain, some volunteer doctors were teaching medical skills to village nurses. Amy heard Betty drive off hours ago. “She should have taken me with her. She thinks I’m too young,” Amy thought. “But she’s wrong. I am already 15!”

Amy carried the milk back to Mama, and then wandered up the road. Roy, a village boy, was trying to stand on a horse’s back. “No wonder they don’t trust kids with anything important,” Amy thought.

She had just turned away when she heard a heavy fall and a few cries. Roy was on the ground. “Roy!” The kids nearby ran towards him. “Get Betty,” one said. Amy shook her head. “Betty’s gone to the city.”

The kids didn’t know what to do. Amy ran to Roy and saw one of his legs out of shape. A broken leg! She remembered what the first-aid book said about it.

“Victor!” Amy called to one of the boys. “Go get Roy’s mama, and find someone with a truck.” She turned to the others. “Give me your shirts. We need something to tie his leg with.”

Amy then found a strong, straight stick. She carefully wrapped the shirts around Roy’s leg and the stick. Roy cried out in pain. “I know it hurts,” Amy said softly. “But this will hold it still until you get to the hospital.”

When Amy was done, she looked up and saw Roy’s mama and a man watching beside a truck. “Thank you, Amy,” Roy’s mama said. Amy helped them lift Roy into the truck, and then they drove down the hillside towards the hospital.

The next day, Betty came to Amy’s home. “I heard what you did,” Betty said. “You kept your head in an emergency. That’s an important skill.”

Amy’s face turned red. “I was afraid...”

Betty shook her head. “It’s OK for a nurse to be afraid, as long as she has a clear head. The volunteer doctors are coming tomorrow with vaccines(疫苗). We need some more hands. Can you help?”

“I’d love to,” Amy replied at once.

“Come early, then. There is a lot to learn.” Amy smiled. “I’ll bring my first-aid book.”

Burns

Burns from fire or other sources of heat are different from mild（轻微的）to life threatening. Some burns can be treated at home. While others need emergency（紧急的）medical care.

·First, check and decide if you can take care of the burn yourself. Go to the hospital immediately if the burn is serious.

·If you can’t get to a hospital right away or must wait for an ambulance, follow these steps:

Remove clothing from the burned area. Do not remove clothing that is stuck to the skin and don’t break any blisters（水泡）.

Run cool (not cold) water over the burn until the pain becomes lighter. Do not put butter, Oil, or ice on burns.

Lightly apply a bandage（绷带）over the burn.

Remove jewelry that’s close to the burn.

The burn is serious.

The burned area is large (cover the area with a clean, soft cloth or towel).

The burn comes from a fire, electrical wire or chemicals.

The burn looks infected（被感染的）.

Be careful when using candles, heaters, and curling irons. Do not allow children to play in the kitchen while someone is cooking. Children can easily get burned in kitchens.
