Objective To study the current status of catheter - related thrombosis(CRT)in Chinese children through a retrospective analysis of the inpatients in the Department of Medicine,Beijing Children's Hospital Affiliated to Capital Medical University. Methods The clinical data of the inpatients with CRT from November 2010 to November 2013 were collected retrospectively,and the causes,clinical symptoms,diagnosis,treatment and prognosis were ana-lyzed. Results There were 42 cases of children with CRT in Beijing Children's Hospital Affiliated to Capital Medical University. Among the cases,the male to female ratio was 1. 0:0. 5;the median age of onset was 88(2 - 186)months with ﹤ 1 year old counted for 16. 7%(7 / 42 cases)and 13 - 14 years old counted for 11. 9%(5 / 42 cases);the distri-bution differences between the male and the female age were not significant(P = 0. 826). The median time from cathe-terization to CRT onset was 9(1 - 81)days,0 - 10 days after catheterization was the peak of onset(52. 5% ,21 / 40 ca-ses)followed by 10 - 20 days(35. 0% ,14 / 40 cases). The protopathy was usually hematologic tumor,kidney disease or deep fungal infection. Slightly more cases developed CRT on the right side(57. 1% ,24 / 42 cases)than on the left side (38. 1% ,18 / 42 cases). All cases were diagnosed by using B - ultrasound,of whom 28. 6%(12 / 42 cases)were symp-tom - free. After being diagnosed,7. 1%(3 / 42 cases)were treated with conservative methods such as immobilization of the affected limbs and hot compress;7. 1%(3 / 42 cases)had catheter removed;anticoagulant and/ or thrombolytics after catheter removal used in 33. 3% patients(14 / 42 cases). After 1 week,22 cases were reviewed,of whom 54. 5%(12 / 22 cases)had thrombosis reduced(all with intervention),thrombosis growing in 22. 7% patients(5 / 22 cases), and thrombosis did not change in 22. 7% patients(5 / 22 cases). Three cases needed re - catheterization after catheter removal,and all of 3 cases had CRT recurrences(100% ). Conclusions CRT is more common among infants and senior children. CRT usually develops within 20 days after catheterization. Children with hematologic tumor,kidney disease or deep fungal infection are more likely to have CRT. Routine ultrasound test should be conducted to monitor CRT in catheterized children. Once CRT is diagnosed,patients need to be treated with anticoagulants and/ or thrombo-lytics. Catheter should also be removed if necessary. Recatheterization can result in CRT recurrence.

The clinical and laboratory data of a patient with chronic refractory immune thrombocytopenia (ITP) who had a significant increase in the proportion of inhibitory T cells in the hematological oncology center of Beijing Children′s Hospital Affiliated to Capital Medical University in February 2018 and regularly followed up in the outpatient department received a retrospective analysis.This 8-year-old patient′s clinical features were 6 years of skin and mucous membrane bleeding spots and petechiae recurring, with occasionally nasal epistaxis.Physical examination: cardiopulmonary abdomen and nervous system examinations are normal, and no superficial lymphadenopathy is touched.Blood routine indicated that the platelets were 2.00×10 9/L, and white blood cell count and hemoglobin level were normal.Bone marrow suggested that hyperplasia was significantly active, with more than 300 megakaryocytes.The patient was diagnosed with ITP, and he was treated with first-line treatment with gamma globulin and oral Corticosteroids.The first-line treatment with high-dose Dexamethasone therapy was repeated, and the second-line treatment was low-dose Rituximab combined with high-dose Dexamethasone.Evaluations had been conducted with every relapsed course, and Cyclosporine was administered orally on the basis of the highly suppressive T cells.After half a month, the child achieved partial remission and continued for 3 months, and then reached a complete remission of 6 months (till this paper). It is suggested that, with ITP as an immunological disease with high heterogeneity, the immune abnormality index is expected to become a breakthrough in the development of precise treatment.
