新华社长沙7月6日电（记者帅才）暑期来临，孩子们有更多时间参加体育锻炼。记者近日从长沙市部分医院了解到，近期医院骨科收治发生运动损伤的青少年患者增多。    Chinese Premier Li Qiang has signed a State Council decree publicizing a decision to revise the Regulations on Management of Housing Provident Fund, which will take effect on Sept. 20, 2026.    According to the decision, the scope of the fund's withdrawal and use will be expanded. For those withdrawing from the housing provident fund to pay rent, the eligibility threshold requiring rent to exceed a prescribed proportion of a household's wage income will be removed.    Housing provident fund savings can be withdrawn for new purposes under the revised regulations, including renovating the homes the contributors live in and paying property management fees for such homes.    The decision also states that the channels for the investment and utilization of the housing provident fund will be appropriately broadened, specifying that housing provident fund management centers are allowed to use the funds to purchase policy-oriented financial bonds.    To enhance the efficiency of management services, the decision also underscores efforts to simplify the procedures for employees to apply for housing provident fund withdrawals and to shorten the review period for housing provident fund loan applications.    The decision, which strengthens risk prevention and control, stipulates that housing provident fund management centers should establish comprehensive, complete and accurate credit records and incorporate them into the national credit information sharing platform.    Amid efforts to expand the coverage of the system, the decision clarifies that individual business owners, part-time employees and other people in flexible employment can pay voluntary contributions into the housing provident fund and enjoy policy support in accordance with the regulations.                    。专家提醒，青少年暑期运动要注意安全，合理选择运动项目。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 | 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。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。

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。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。
