Objective To establish a neuropathic pain model by transection of L4 spinal nerve in rats.Methods Twenty-eight male SD rats weighing 270-310 g were randomly divided into 3 groups: A experimental group (n = 12) received transection of right L4 spinal nerve; B sham operation group ( n = 8) in which right L4 spinal nerve was exposed but not transected and C control group ( n = 8) received no surgery. The paw withdrawal threshold (PWT) to mechanical stimulation was measured by using modified von Frey test. The response to cold stimulation evoked by applying acetone to the plantar region of hindpaw was measured and scored. The threshold to both noxious mechanical and thermal stimuli was measured once a week for 8 weeks. Results In experimental group the pain threshold to mechanical stimuli (von Frey hair stimulation) and cold stimuli (acetone test) on the operated side were significantly decreased after L4 spinal nerve transection as compared to the baseline values before operation and significantly lower than in sham operation and control groups. There was no significant change in the withdrawal response of the hindpaw to mechanical and cold stimuli after surgery on the unoperated side. Conclusion Hyperalgesia to mechanical and cold stimuli develops after L4 spinal nerve transection on the operated side and lasts more than 8 weeks

Objective:To establish a volt-ampere polarography method for the determination of thimerosal in chondroitin sulfate eye drops, and study the adsorption of thimerosal in different packing materials. Methods:The hanging mercury drop electrode ( HM-DE) in multi-functional electrode was used and the sample solution was added to potassium chloride-hydrochloric acid buffer solution. Nitrogen deoxygenation time was 200 s, the enrichment time was 60 s, and the equilibrium time was 5 s. The potentiometric scan was performed using a two standard addition method. Results:Thimerosal had a good linear relationship within the range of 0. 01-1. 0 mg· ml-1(r=0. 9990). The detection limit was 1. 78 μg·ml-1 and the average recovery was 99. 1% (RSD=2. 7%, n=9). Conclu-sion:The method is simple and accurate, and suitable for the determination of thimerosal in chondroitin sulfate eye drops. Low-density polyethylene and polypropylene both show obvious adsorption of thimerosal,so chondroitin sulfate eye drops should not be packed in the above packing materials.

Objectives To detect the clinical significance of high sensitive C-reactive protein (hs-CRP) and immune function in children with Mycoplasma pneumoniae pneumonia (MPP). Methods 103 children with MPP, 47 cases of systemic inflammatory response syndrome (SIRS group), 56 cases of non-systemic inflammatory response syndrome (non-SIRS group) were recruited. 26 healthy children served as the control group. ELISA was used to detect the level of serum hs-CRP, immune in-dexes, IgG, IgA, and IgM, Cellular immune CD3+, CD4+, CD8+, CD4+/CD8+. Results The level of serum hs-CRP、IgG、IgM and CD8+in control group were significantly lower than those in non-SIRS group and SIRS group (P<0.05). The level of IgA、CD3+, CD4+, CD4+/CD8+in control group were significantly higher than those in non-SIRS group and SIRS group (P<0.05). The level of serum hs-CRP、IgG in SIRS group were significantly higher than those in non-SIRS group (P<0.05). The level of IgA、CD3+、CD4+、CD4+/CD8+in SIRS group were significantly lower than those in non-SIRS group. There was no significant difference in non-SIRS group and SIRS group of IgM and CD8+(P>0.05). The level change of serum hs-CRP were positively related with IgG (r=0.66,P=0.001) and were negatively related with IgA、CD4+、CD4+/CD8+(r=0.79, 0.67, 0.82, P all were<0.05) in chil-dren with MPP.
