Objective To investigate the enhancing effect of Celecoxib on the anti-proliferative effect of cisplatin (DDP) against human cervical carcinoma HeLa cells and to explore the possible mechanism. Methods After treatment of HeLa cells with Celecoxib or/and DDP, the growth suppression of HeLa cells was measured by MTT assay. Cell cycle and apoptosis were examined by flow cylometry. Results The inhibition of Celecoxib on HeLa cells was dose -dependent and time -dependent.The inhibitory effect was remarkable enhanced in asynergistic or additive pattern after treatment with the combination of Celecoxib and DDP (P =0.000) . Celecoxib (50 μmol/L) and DDP (16 μmol/L) could respectively induce the apoptosis of HeLa cells and this effect of apoptosis induction was increased when combinated Celecoxib with DDP. They could change cell cycle of HeLa cells lines with G_0/G_1 phase cells increasing and S phase cells decreasing. Conclusion Celecoxib combined with DDP shows synergistic anti-tumor effects.

Univariate analyses revealed that the disorder of DR was positively correlated with the duration of diabetes, microalbuminuria, blood cholesterol (P<0.01 or <0.05), and negatively correlated with the glomerular filtration rate (P<0.01). Conclusion The incidence OFDN and DR has the highly concordance, and their lesions have some parallel relationship.

Potency is one of the most important indexes of inactivated vaccines.A number of methods have been established to assay the potency,of which the NIH test and single-dose mouse protection test are the prescribed methods.Here,we report a method to semi-quantitatively assay the potency of an inactivated rabies vaccine,which uses fewer animals and takes less time to complete.Depending on the quality requirements of a vaccine(e.g.minimum potency),a rabies reference vaccine is,for example,diluted to the minimum potency,and 50 μL of the dilution is taken to inoculate 10 mice.The same amount of the test rabies vaccine is inoculated into another 10 mice.After two weeks,all mice are bled and serum samples are assayed for viral neutralizing antibody by the fluorescent antibody virus neutralization(FAVN) test.By comparing the median and interquartile range of antibody titers of the reference vaccine with those of the test vaccine,the test vaccine potency can be semi-quantitatively judged as to whether it is in accord with the required quality.The reliability of this method was also confirmed in dogs.The procedure can be recommended for batch potency testing during inactivated rabies vaccine production.
