Rescue teams have been using boats in relay operations to deliver emergency supplies to stranded residents, local authorities said. The flooding in Shangjin Township has affected 1,479 households, or 3,719 people, according to Hou Yong, a local official. As of 9:30 a.m. Tuesday, 27 village settlements in the township had been cut off due to damaged roads. Power supplies had been disrupted in 22 settlements, while four had lost internet access and 14 were without running water. Floodwaters had entered 329 homes, affecting 902 people, while more than 20,000 mu (about 1,333 hectares) of cropland had been submerged. All residents of the flooded homes had been evacuated and relocated in advance, Hou said. More than 60 rescuers were mobilized in Shangjin Township on Tuesday, using assault boats and inflatable dinghies to establish emergency water-and-land supply routes. Meng Lichun, head of Shangjin Township, said most stranded villagers had moved to the upper floors of their homes and did not require large-scale evacuation. The immediate priorities were delivering daily necessities and providing emergency medical assistance to critically ill patients, she said. Rescue teams aimed to complete supply deliveries to remote villages before nightfall. The local emergency command post had three assault boats at its disposal, with two used to transport supplies and one kept on standby for emergency response. At 5:30 p.m., rescuers reached Huashan Tun, where residents who had been stranded by floodwaters finally received relief supplies. "I'm 54 years old, and I've only seen flooding this severe once before, in 1986," said villager Huang Xuhua. The water rose rapidly, Huang said. After the village lost power, refrigerators stopped working, raising concerns among some residents about food shortages. The timely arrival of government supplies had helped ease the immediate difficulties, he added. Fu Quan, a township official, said rescue teams distributed milk, bread, porridge, bottled water and other necessities based on the needs of affected villages. Authorities had issued early warnings ahead of the flooding, advising residents to move electrical appliances and gas canisters to upper floors. Personnel were also assigned to purchase and deliver supplies to elderly residents, people who were ill and those with limited mobility. Emergency supply coverage had been secured for all six affected settlements in Yunjiang Village. Medicines for remote communities were being delivered by drone and assault boat to ensure residents' basic medical and daily needs were met. "We have successfully transferred three patients with uremia over the past two days and taken them to Longzhou County People's Hospital for dialysis," Meng said. (By Zhang Dongfang) 
。长沙市第三医院骨科副主任医师张卓介绍，近期发生跟腱损伤的青少年患者增加。
三 | 有的青少年在踢足球时和伙伴进行激烈身体对抗，发生了跟腱断裂。
四 | 长沙市第三医院骨科二十三病室主任陈松介绍，跟腱是人体最强壮的肌腱，它的主要功能是传导小腿肌肉力量至足部，是支持人体直立、完成跑跳等动作的“主力”。突然的蹬地动作、猛烈跑跳等动作容易导致跟腱断裂。
五 | 跟腱一旦断裂，脚后跟会出现明显的疼痛、肿胀，无法完成单脚踮起脚尖、提起脚后跟的动作，不能正常行走。
六 | 专家提醒，青少年在运动时，如果听到跟腱处有“啪”的断裂声，并且局部出现可触及的凹陷，脚后跟肿胀、疼痛时，就要考虑跟腱断裂的可能，应立即停止一切活动，以免造成断裂的加重，及时到医院进行检查和治疗。陈松提醒，青少年在运动之前，应进行充分的热身活动，舒展全身的关节、肌肉，降低受伤的风险；青少年要根据身体条件选择合适的运动方式，避免突然过猛地进行跑跳等动作；青少年在打篮球、踢足球等激烈运动中可以戴相应护具，加强对肌肉和关节的保护。专家提醒，青少年可以找专业教练根据自己的体重、身高、肌肉水平等设计训练方案和计划，还可以到医院运动科进行测试，了解自己的心肺功能情况，并根据自身情况设计科学的运动方案。湖南省人民医院儿科门急诊主任曾赛珍提醒，青少年骨骼相对于成人骨骼来说更柔软，在进行一些激烈运动时更容易骨折变形。
七 | 青少年可以根据自身生长发育特点，选择慢跑、跳绳、仰卧起坐、游泳、健身操等运动。中南大学湘雅三医院儿科副教授陈志衡建议，青少年在酷暑时节不要进行激烈的户外运动，以免发生严重中暑。
