[Method] The cuttings of 1, 2 or 3 years old, with different length, were soaked in different hormones at different concentrations for different time and planted at different dates. Finally, their rooting rate and survival rate in different treatments were measured and compared. [Result] The rooting rate and survival rate of one-year old cuttings with length of 10-13 cm and planted on September 20 and October 20, 2012 were relatively higher among all the treatments. Hormone treatment could significantly promote the callus formation and accelerate the rooting of the cuttings, and improve their survival rate. The cuttings treated with 120-200 mg/L ABT1 or NAA for 35-45 min had higher rooting rate and survival rate. Among them, the survival rate of cuttings treated with 160 mg/L ABT1 for 35 min was the highest, up to 92.5%. [Conclusion] The study provided basis for improving the survival rate of L. japonica by cuttage, and for optimizing the rapid propagation technique.展开更多

Methods： Retrospective study of 7 patients with hepatic angiosarcoma. Results： Symptoms and signs such as abdominal pain were extremely nonspecific. The levels of the tumor markers were within the normal range. Four cases were positive for hepatitis B viruses. Among the 5 patients who received chemotherapy, improvement in survival was seen in 3 cases which also received surgery. Conclusion： Hepatic angiosarcoma is a rare and diffficult-to-diagnose malignant liver tumor. Surgery is the definitive treatment and adjuvant chemotherapy after surgery may improve survival.展开更多
