Objective To observe the expression of zinc finger protein A20(A20), NF-κB and related inflammatory factors before and after lipopolysaccharide (LPS) stimulates degeneration of rabbit intervertebral disc nucleus pulposus cells.Methods The normal and degenerative nucleus pulposus cells were isolated and cultured, then divided into normal group,degenerative group,LPS stimulation group and NF-κB inhibition group.HE staining observe the morphological changes of nucleus pulposus and annulus fibrosus,immunohistochemistry was used to detect the expression of A20,NF-κB/p65 and COL-Ⅱ.Real-time PCR was employed to analyze the expression of A20,IL-1β,TNF-α,NF-κB and COL-Ⅱ,Western blot was used to observe the A20 protein,p65 and COL-Ⅱexpression in the four groups, and TNF-α, IL-1β in cell supernatant was determined by ELISA.Results The number of nucleuspulposus cells significantly decreased, aggregation occured in the degenerative group.COL-Ⅱ was obvious lower and A20, p65 significantly higher than that in normal group by immunohistochemical staining.Compared with the normal group,A20,TNF-α,IL-1β,p65 expression was significantly increased and COL-Ⅱ decreased in the mRNA and protein levels in degenerative group.Above indexes changed more significant in LPS stimulation group than in degenerative group.The expression of A20, TNF-α, IL-1β, p65 in the NF-κB inhibitor group was lower than that in the LPS group, and the expression of type Ⅱ collagen increased(P<0.05).Conclusions Intervertebral disc inflammatory response is closely related to the development of intervertebral disc degeneration, A20 may play an important role.

Objective To evaluate the molluscicidal effect of suspension concentrate of niclosamide ethanolamine salt(SC-NE)against Oncomelania hupensis snails in laboratory and field. Methods The experiment of SCNE against the snails by using the immersing and spraying methods was performed in laboratory and field,with control groups of wettable powder of ni-closamide ethanolamine salt(WPN). Results In the laboratory,LC50(s) of SCNE for 24,48 h and 72 h by using the immersion method were 0.0926,0.0629 mg/L and 0.0549 mg/L,respectively. The mortality rates of snails for 24,48 h and 72 h by using the immersion method were all 100％ with the concentrations of 0.25 mg/L. The mortality rates of snails were all 100％ while spraying SCNE for 3 d in the laboratory with the concentrations of 0.25 g/m2. In Jiangling County,except 0.5 g/m3 SCNE immers-ing the snails for 24 h,the mortality rates of snails by using SCNE with the immersing method were all 100％. While the concen-tration of SCNE was 0.5 g/m3 or above,the mortality rates were all 100％after the use of it with the immersion method for 2 d in Gong'an County. In Jiangling County,the mortality rates of snails by using SCNE 0.5 g/m3 for 1 d,3 d,and 7 d with the spray-ing method were 87.5％,92.82％and 97.40％respectively. While the concentration of SCNE was 0.5 g/m3,the mortality rates were 85.94％,86.78％and 94.21％respectively after the use of it with the spraying method for 1 d,3 d,7 d in Gong'an Coun-ty,and the molluscicidal effect of SCNE(1.0 g/m2)was higher than that of WPN. Conclusion SCNE has a high molluscicidal effect in the laboratory and field,and it is a novel and simple formulation of niclosamide.
