Janus kinase 2,myeloproliferative leukemia virus and tet encogene family member2 mutations affect a variety of cytokines signal transduction pathway in BCR/ABL-negative myeloproliferative neoplasms (MPN). In the influence of mutation load,co-mutation and genetic susceptibility,these mutations can induce different MPN phenotypes,and affect the characteristics of patients,the distribution of peripheral blood cells and prognosis. But how these mutations contribute to disease initiation,development,and transformation needs further reseach.

Objective To investigate the effect of cobalt chloride on tumor cell proliferation and apoptosis in vitro, to explore the reasonable strategy of chemical hypoxia induced by CoCl2. Methods Two tumor cell lines (A549 and HeLa) were respectively exposed to CoCl2(0.05～2 mmol/L) for different time period (4～48 h), cells viability、proliferation and apoptosis were maesured by MTT and FCM methods. HIF-1? and related apoptosis proteins expression were detected by Western blot. Results Cells viability was weakly changed in low concentration(≤200 ?mol/L)of CoCl2 within 24 h. However, higher dose or prolonged challenge of CoCl2 significantly decreased cell survival rate (P

Objective To explore the effect of oxytocin on uterine fibroids treated by ultrasound ablation. Methods Eighty-two single points in 29 uterine fibroids from 26 patients were sonicated with magnetic resonance imaging guided by high intensity focused ultrasound before and after using oxytocin. The required total energy, sonication time required to reach 60 ℃ and the acoustic energy for increasing 1 ℃ of temperature at the single point before and after using oxytocin were compared. Results Before intravenous infusion of oxytocin, the average total sonication energy required to reach 60 ℃ was (5320 ±910) J and it took (21 ±20) seconds for sonicating a single point, the energy required for increasing 1 ℃ was (255 ± 302) J. In contrast, after intravenous infusion of oxytocin, the average total sonication energy required to reach 60 ℃ was (2890 ±325) J, and it took (12 ±7) seconds for sonicating a single point, the energy required for increasing 1 ℃ was ( 126 ± 94 ) J. Those three index all reached statistical difference ( P = 0.002, P = 0.001, P= 0.002, respectively). Conclusion It seemed that Oxytocin could significantly decrease the energy required for ablating uterine fibroids, shorten treatment time and improve the treatment efficiency.
