Promyelocytic leukemia (PML) protein can regulate many cellular processes, Here we summarize the role of PML protein in cell and mechanisms according to researches in recent years.

Objective To assess the value of procalcitonin( PCT) in anti-infective therapy by observing PCT concentration change in therapy. Methods Sixty-eight patients with bacterial infection meet the diagnostic criteria were divided into effective group and invalid group,the PCT level on day 1,day 3,day 5 and day 7 were observed respectively. Results PCT concentrations of two groups showed no sig-nificant difference on day 1. The PCT level of effective group gradually declined and PCT level of invalid group gradually rised with significant difference on day 3,day 5 and day 7(P<0. 05). Conclusion PCT level that is positively correlated with inflammation of infectied patients, which can be used as an effective indicator to optimize antibiotic therapy.

This study was aimed to find the optimal conditions for seed propagation of Fritillaria cirrhosa in the plateau region in order to summarize the best sowing time and method of artificial propagation. Seeds were stored in appropriate environment. After the seeds matured, the seedbed of F. cirrhosa was treated with cattle dung humus and small shed. The results showed that early March is the best sowing time and cattle dung humus with a thickness about 1 cm is the best coving for propagation of F. cirrhosa; the growing period of film propagation (FP) is about 160 days each year compared with that of control about 50-60 days, respectively. It was concluded that the propagating seeds in plastic greenhouses by using cattle dung humus as planting substrates, using sunshade nets for shading and keeping humidity by spraying can effectively prolong the growing period, improve the retention rate of annual bulbs and the production of F. cirrhosa.

[Objective]To evaluate the methods of operation and clinic effective of thoracolumbar spinal tuberculosis with paraplegia.[Method]Thirty cases of thoracolumbac spinal tuberculosis with paraplegia had been treated with primary anterior debridement,decompression of spinal cord,interbody graft bone,and interbody fixation,anti-tuberculosis drug was taken at 18 monthes ofter the operation.[Result]Thirty cases were followed-up for an overage of 19 months and were healed,in which 2 cases recurrence,29 cases spinal fusion of graft bone,12? of kyphosis correction had been gained,the neuropathic fuction had gained improvement excellently(90%).[Conclusion]It had gained good outcome that operation of the primary anterior debridement decompression of spinal cand interbody graft bone and interbody fixation to treat thoracolumbac spinal tuberculosis with pacaplegia.

Objective To investigate formalin-induced nociceptive behavior and c-fos expression of interbrain following stellate ganglionic block (SGB) in rabbits. Methods Catheters were inserted closely to right stellate ganglia in rabbits by operation.One week later,twenty-four rabbits were randomly divided into three groups, each group containing 8 animals. groups A,B and C received 0.5ml of normal saline,3% formalin and 3% formalin stimulation by intraplantar injection , respectively. 10 minutes before stimulation,0.5 ml of 0.25% bupivacaine was administered via the catheter in group B, while in groups A and C 0.5 ml of normal saline was applied. Nociceptive behavior was observed for 1 hour using weighted pain score. 2 hours after stimulation, whole interbrain was removed to immunohistochemically detect the expression of c-fos. Results Formalin-induced nociceptive behavior in phase 2 was relieved following SGB, c-fos expression level of hypothalamus in group B was significantly lower than that in group C(P0.05). Conclusion SGB could relieve formalin-induced nociceptive behavior, and downregulate formalin-induced c-fos expression of hypothalamus, which may be related to the mechanisms of SGB for the treatment of inflammatory pain.
