Objective To investigate the synergistic effect of 11 β-hydroxysteriod dehydrogenase (11 β-HSD1) and S100A16 on the differentiation of3T3-L1 preadipocytes and its mechanism.Methods Lentiviral vectors PLJM1-11β-HSD1 and PLJM1-S100A16-GFP were respectively constructed and co-transfected into 3T3-L1 preadipocytes.The cell strains expressing 11 β-HSD1/S100A16 were screened with 2.5 μg/ml puromycin for two weeks.Western blot was employed to verify the lentiviral carrier transfection effects.The expressions of marker genes related to the adipocyte differentiation were detected by mean of realtime PCR.Oil red O staining was used to observe the lipid droplet accumulation and the content of triglyceride was measured after differentiation of preadipocytes.The effect of 11β-HSD1 and S100A16 on PPARγ promoter activity was detected by luciferase reporter gene.Results Compared with the empty vector group,the expressions of 11β-HSD1 and S100A16 protein in the lentivirus cotransfected 3T3-L1 cell strain were significantly higher.After 3T3-L1 cell strain co-expressing 1 1β-HSD1 and S100A16 was induced to differentiate for 8 days,the lipid droplets accumulation and triglyceride content were siginificantly increased,along with increased expressions of adipocyte differentiation marker genes such as PPARγ,CCAAT/enhancer binding protein α,lipoprotein lipase,fatty acid synthase,and adipocyte fatty acid-binding protein,in comparison with 11 β-HSD1 or S100A16 overexpression.The result of reporter gene indicated that 11 β-HSD1/ S100A16 enhanced PPARγ promoter activity.Conclusions 11β-HSD1 and S100A16 may jointly promote the differentiation of 3T3-L1 preadipocytes through a synergistic effect on PPARγexpression and play a critical role in the development of obesity.

To improve 3-ketosteroid-△1-dehydrogenase(KSDH) activity and the transformation level for androst-4-ene-3,17-dione, 3-ketosteroid-△1-dehydrogenase gene(ksdD) from Arthrobacter simplex was cloned into plasmid pWB980 and expressed in B. subtilis WB600 under the control of promoter P43. The molecular weight of expressed enzyme was about 55kDa by SDS-PAGE analysis. The activitities assayed by spectrophotometrical method of intracellular and extracellular soluble enzyme were 110?0.5mU and 15?0.6mU per milligram of protein respectively. The transformation rate of androst-4-ene-3,17-dione by the B. subtilis recombinant cells was 45.3%. Compared with Arthrobacter simplex, the enzyme activity of KSDH expressed in B. subtilis was improved about 30 fold, and the transformation level of androst-4-ene-3,17-dione by the B. subtilis recombinant cells was improved about 10 fold. The recombinant B. subtilis cells used in biotransformation of steroids provided a new way for steroid medicines production.

In order to test the equilibrium solubility of puerarin in different solvents and solubilizer,cilia toxicity and irritation of these excipient, the balance method, toad in the ciliary body toxicity and rat nasal mucosa irritation were used respectively. Results showed that puerarin solubility was 56.44 g x L(-1) in combined solvent of 30% PEG200 and 10% Kolliphor HS 15. With normal saline solution as negative control and sodium deoxycholate as positive control, the effects of 30% PEG200, 30% PEG 400, 10% Kolliphor HS 15 and combination of 30% of PEG200 and 10% Kolliphor HS 15 on toad palate cilium were observed and cilia movement duration was recorded. The results indicated that there was no significant difference in cilia movement duration among 30% PEG200, 10% Kolliphor HS 15 and normal saline group. The rats long-term nasal mucous membrane irritation of 30% PEG 400, 10% Kolliphor HS 15, which had no cilia toxicity, was studied, with normal saline solution as negative control. There were no significant difference revealed on rat nasal mucosa epithelial thickness among 30% PEG 400, 10% Kolliphor HS 15 and normal saline. Above researches showed 30% PEG 400, 10% Kolliphor HS 15 was ideal for solubility of puerarin nasal drops and showed a lower cilia toxicity and irritation, and can be used as the solvent and solubilizer of puerarin nasal drops.

BACKGROUNDSilicon gel is unfavourable for cell attachment and growth. This study was to study if pretreating the surface of silicon gel with chemical agents affects the proliferation of epithelial cells.
METHODSSilicon gel was made and treated with either mixed acid solution (containing 232 g/dm(3) of H(2)SO(4) and 8 g/dm(3) of K(2)Cr(2)O(7)) or 300 cm(3)/dm(3) peroxide for 5, 10, and 15 minutes or 10, 15, and 20 minutes, respectively. The cultured corneal epithelial cells were seeded onto those silicon gels and kept for 13 days. Immunohistochemical investigations were then carried out for integrin (alpha 6 or beta 4) and actin.
RESULTSGrowth of the epithelial cells in silicon gels treated with mixed acid solution for 10 minutes and 15 minutes was much significant than that in the untreated gels. After a 12-hour culture, a small number of corneal epithelial cells were proliferated on the surface of the silicon gels that had been treated with peroxide for 15 minutes. After a 3-day culture, those cells were further proliferated and fused together. The corneal epithelial cells did not grow well in the silicon gels treated with peroxide for 10 or 20 minutes. Immunostaining revealed the expression of actin and integrin alpha 6 or beta 4 on the silicon gels that were treated with mixed acid solution for 10 minutes or peroxide for 15 minutes.
CONCLUSIONSilicon gels treated either with mixed acid solution for 10 or 15 minutes or with peroxide for 15 minutes improves cell proliferation.
