Linlin, a 13-year-old girl, was diagnosed with acute B-lymphoblastic leukemia in 2018. However, she had no response to multiple courses of chemotherapy. She received the first hematopoietic stem cell transplant in her hometown in October 2019. Unfortunately, her leukemia relapsed in October 2020.

Linlin came to GHG medial center with her parents for further treatment in 2021. She was recommended to first receive CAR-T treatment, followed by hematopoietic stem cell transplant after careful evaluation by GHG medical team. Accompanied by the GHG team, she successfully received CAR-T therapy and the second hematopoietic stem cell transplant. She went through difficulties including nausea, vomiting, fever, and rejection and was discharged from the hospital. More than two years have passed since the second transplant, and there have been no other serious post-transplant complications. Linlin said happily, "The sky in Beijing is so blue." when she walked out from GHG medial center because she had a good re-examination recently.
