Objective To observe the effect of stress caused by neuropathic pain on serum cortisol concentration and expres-sion of 11β-hydroxysteroid dehyarogenase 1(11βHSD1)and investigate the action mechanism of curcumin for alleviating neuropathic pain. Methods The 72 male SD rats were randomly divided into 4 groups with 18 rats in each group:sham operation group(Sham), chronic constrictive injury group(CCI),solvent contrast group(SC)and curcumin treated group(Cur100). Curcumin(100 mg/kg/d) was given after the operation in Cur100 group. Paw thermal withdrawal(PTWL)and paw mechanical withdrawal threshold(PMWT)of rats were measured on 2 pre-operative and 1,3,5,7,10,and 14 post-operative days. The animals were deeply anesthetized,the blood was taken from the heart,and the L4-L5 dorsal root ganglion(DRG)of the operated side was removed. The change of cortisol was measured by ELISA and the change of 11βHSD1 expression in spinal cord and DRG was determined by immunochemistry and Western blot. Results Compared with sham group,PTWL and PMWT decreased significantly after operation in CCI group(P<0.01),serum cortisol concentration was significantly increased(P<0.01)and the expression of 11βHSD1 was significantly increased in CCI group(P<0.01). Compared with CCI group,the PMWT and PTWL was increased in CCI group(P<0.05),the serum cortisol concentration was decreased(P<0.05)and the expression of 11βHSD1 was inhibited in Cur100 group(P<0.05). Conclusion Stress caused by neuropathic pain triggered the release of cortisol to the blood and increased the expression of 11βHSD1 at the same time. Cur-cumin could alleviate thermal hyperalgesia and mechanical hyperalgesia induced by CCI and could also inhibit the serum cortisol con-centration and the expression of 11βHSD1 in spinal cord and DRG,which was likely to be related to pathogenesy and maintenance of neuropathic pain.

Objective To investigate the effects of polysaccharide from Spirulina platensis (PSP) on the growth of HeLa cells. Methods The antiproliferation activities of PSP on HeLa cells were evaluated by MTT assay. The morphologic changes of HeLa cells were observed under light microscope. Cells division cycle was measured by flow cytometry. Results It was showed that with the increase of PSP concentration, the inhibited rate on HeLa cells increased and the survived rate declined; The HeLa cells exposed to PSP for 24～48h displayed significant morphologic changes; PSP had a specific effect on the HeLa cell division cycle, increased the number of cells in phase G 1. Conclusion These results indicated that the effects of PSP on HeLa cells may probably be attributed to increase of the number of cells in phase G 1.

This paper is to study the inhibitory effect of water soluble polymers--methyl cellulose (MC), hydroxypropyl methyl cellulose (HPMC), hydroxypropyl cellulose (HPC-M), poloxamer (F68) and polyvidon (PVP) on osthole (OST) crystallization and investigate the impact of polymer concentration and viscosity on crystallization behavior. Also, UV spectrophotometry method was used to determine the drug concentration at different time point to draw the OST concentration-time curve. Results show that HPMC has the most significant inhibition effect on OST crystallization, and drug concentration level is 1.61 times higher than that in control solution within 8 h followed by PVP (1.54) and MC (1.45) respectively. The kinetics of OST recrystallization can be described using first-order reaction, and the crystallization rate constants obtained by analyzing the regression equation indicate that HPMC-60SH-4000 and HPMC-60SH-10000 can greatly influence OST crystal formation. The dissolution rate of drugs precipitated from water-soluble polymer solutions is faster compared with controls in pH 1.2 HCl and pH 6.8 phosphate buffers, which demonstrated that water-soluble polymers can not only change the behavior of drug crystallization but markedly improve the dissolution rate of water insoluble drugs.

Objective　To obtain staphylococcal enterotoxin B (SEB) mutant with normal antigenicity but low toxicity. Methods　Using PCR technique, normal SEB (SEB-N) gene which was amplified from S. aureus S6B. SEB mutant gene (SEB-M) was prepared from the same strain, but one nucleotide in SEB gene was changed from asparagine (N23) to serine (S23). SEB-N and SEB-M were cloned into procaryotic expression vector pTrc99A then and transferred into E. coli JM109. SEB-N and SEB-M which were cloned into plasmid were sequenced directly by dideoxynucleotide method. The crude expressed proteins were identified by double agar immunodiffusion. The level of IL-2 in supernatants of mouse splenocytes stimulated by crude expressed proteins was determined by ELISA. Results　SEB-N and SEB-M were obtained through PCR. The sequence of SEB-N was changed with non site-directed mutagenesis, threonine at the residue 150 of SEB-N was replaced with alanine (ACT→GCT, T150A). As being expected, at the residue 23 of SEB-M, serine substituted for asparagine (AAT→AGT, N23S) with site-directed mutagenesis. Double agar immunodiffusion showed obvious precipitin line with anti-SEB by both crude SEB-N and SEB-M mutant proteins could produce, but not by non-recombinant strain. ELISA demonstrated that the level of IL-2 in supernatant of mouse splenocytes stimulated by natural SEB protein (containing equal amount of JM109P crude protein) was 40 times as much as that stimulated by SEB-M and 12.5 times as much as that stimulated by SEB-N. Conclusions　We obtained two recombinant strains which produced T150A and N23S mutant SEB protein. The mutant proteins showed binding ability to anti-SEB as the normal protein. However, their biological activity as superantigen decreased sharply. We consider that it is promising for further study of molecular adjuvant or superantigen vaccine.
