Yifan waves goodbye to those who came to see her off when she left for the U.S. for treatment The Beijing News (reporter Ying An) - Recently, not long after her sixth birthday, Yifan, a girl nicknamed "oxygen hood girl" who had been plagued by lung disease, passed away in the U.S. It has been ten months since she went to the U.S. for treatment. Relay rescue At the end of 2009, the urgent need for donations for five-year-old Yifan was reported by many media outlets. Her strength touched many people and numerous netizens started relays to help her. Her parents immediately received donations after revealing their bank account information, and the Children's Medical Foundation of Peking Union Medical College Hospital where Yifan had previously sought medical care also set up a "Yifan Fund" for her. Foreign doctors from that hospital even helped Yifan contact Boston Hospital in the United States for treatment. Pan Junting, Yifan's father, introduced in the blog "This Affection Can Be Waited For" he created for his daughter that the doctor confirmed her condition as "pulmonary cell metabolic defect" leading to "pulmonary arterial hypertension", which caused breathing difficulties and required a full lung transplant for treatment. Untreatable death On March 17 last year, accompanied by her mother, Yifan arrived in the U.S., where local charities donated money to her one after another. Local volunteers and Chinese people also reached out to help, taking turns going to the hospital to accompany Yifan in order to reduce her mother's burden. Yifan's father revealed in the blog that they received about 500,000 US dollars in donations from both inside and outside China, but actually needed 2 million US dollars. Moved by the hardships of Yifan's family, the hospital decided to waive all expenses during her treatment. At the end of April last year, Yifan officially became a candidate for lung transplantation and underwent the surgery in late June. Afterward, it wasn't until late September that her condition gradually stabilized, followed by three infections. At 7:26 am on January 18 this year, Yifan died due to organ failure. Donating her heart Fu Boxue, a staff member of the Children's Medical Foundation of Peking Union Medical College Hospital, introduced that while Yifan was hospitalized there, the hospital established the "Yifan Fund" to accept social donations, all of which were used for her treatment. During Yifan's treatment in the U.S., Peking Union Medical College Hospital also continuously paid attention to her treatment situation and expressed gratitude to the entire society for their care and concern for Yifan. This staff member said that currently, Yifan's parents are still in the U.S. handling their daughter's posthumous affairs. Yifan's parents agreed to donate her heart to patients in need.
