Mutations of CALR, JAK2 have different clinical characteristics and blood pathological changes of Chinese ET patients, and their clinical significance is worth to explore. Mutations of CALR, JAK2 have different clinical characteristics and blood pathological changes of Chinese ET patients, and their clinical significance is worth to explore. To investigate the clinical characteristics of essential thrombocytopenia (ET) patients with positive mutations including JAK2, CALR, MPL, or negative mutations. A total of 66 newly diagnosed ET cases from January 2016 to December 2018 in Department of Hematology, Huaian No.1 People's Hospital affiliated to Nanjing Medical University were analyzed. Statistical analysis data included the patient's sex, age, symptoms, thrombosis and embolism events, spleen omegaly, platelet count (Plt), leukocyte (WBC) count, hemoglobin (Hb), fibrinogen (FIB), thrombus elastic diagram (TEG), serum potassium, blood glucose (GLU), lactate dehydrogenase (LDH), JAK2, CALR and MPL mutations, treatment options, and efficacy. All the patients were not MPL-positive, and divided in three groups JAK2 mutation (46 cases, 69.7%), CALR mutation (9 cases, 13.6%) and gene negative mutation (11 cases, 16.7%) group. The average age of patients in the JAK2 mutation group was 63.2 years old, and significantly higher than that in the CALR mu clinical diagnosis and treatment. To explore the abnormal hemoglobinopathy in couples of child-bearing age in Chongqing. A total of 34 800 subjects of child-bearing age were screened for thalassemia by using capillary electrophoresis from January 2015 to September 2018. PCR-flow cytometry fluorescence hybridization assay was used to detect the common thalassemia gene deletions and mutations. 8 kinds of abnormal hemoglobinopathy were detected in 200 cases from 34 800 subjects of child-bearing age, the detection rate was 0.57% in couples of child-bearing age in Chongqing Among 200
