Objective Co-stimulation cells is a kind of natual killer (NK)-like T cells, which can kill tumor cells.Previous studies show that lupeol , an natural plant extracts , can change the growth of NK cells ,γδT cells and their effects on tumor cells .This study aimed to investigate the effects of lupeol on human co-stimulation cells and colonic cancer cell lines SW 480 . Methods The peripheral blood mononuclear cells ( PBMC) from healthy volunteers were induced in vitro by different cytokines and transferred into Co-simulation cells.After SW480 and Co-stimulation cells were incubated with different concentrations of lupeol for different durations , methyl thiazolyl tetrazolium (MTT) was used to detect the effects of lupeol on co-stimulation cells and colonic cancer cell lines SW480. Lactate dehydrogenase was used to determine the cell-killing activity of Co-simulation cells to colonic cancer lines SW 480 . Results The concentration of lupeol in 0.1-200.0 mg/L promoted the growth of Co-stimulation cells and inhibited the colonic cancer cell lines SW480.When the concentration of lupeol is at 12.5 mg/L, the cell-killing activity of Co-simulation cells to colonic cancer lines SW 480 was enhanced significantly compared with the controls (76%vs 40%, P<0.05). Conclusion Lupeol could promote the prolifera-tion of Co-stimulation cells, inhibit the growth of cancer lines SW480, and strengthen the cytotoxicity of Co-stimulation cells against co-lonic cell lines SW480.

Objective To investigate the effects of sufentanil on activation of spinal astrocytes in mice after unilateral sciatic nerve injury.Methods Eighty healthy male BALB/c mice,aged 6-8 weeks,weighing 18-22 g,were randomly divided into 4 groups (n=20 each): sufentanil high dose group (group H),middle dose group (group M),low dose group (group L) and model group (group MO).After model of sciatic nerve injury was established by unilateral sciatic nerve transection,group H,M and L,sufentanil 10 μg/kg,5 μg/kg,2.5 μg/kg was injected intraperitoneally once a day continuously for 3 days,while the equal volume of saline was injected in group MO.Five mice in each group were selected,and the sciatic nerve functional index were measured at 4,8,12 weeks.The 5 mice were sacrificed from each group and the damage on the same side L4-L6 segments of the spinal cord were removed at 2,4,8,12 weeks.The pathological changes were examined under light microscope at 8 week point.The expression of GFAP was determinatied at each time points by immuno-histochemistry.Results Compared with group L and MO,sciatic nerve functional index significantly was increased in groups H and M (P<0.05),and no significantly change was found in group L.Spinal cord neurons had a better morphology in groups H and M than in group L and MO.Compared with group MO,The expression of GFAP were significantly up-regulated in groups H,M and L (P<0.05).Compared with group L,the expression of GFAP were significantly up-regulated in groups H and M (P<0.05).Conclusion Sufentanil promotes spinal astrocyte activation after peripheral nerve injury in mice and improves repair after peripheral nerve injury.

OBJECTIVETo evaluate the clinical efficacy of syndrome differentiation-based treatment with traditional Chinese medicine (TCM) versus losartan therapy in addition to basic treatment for management of proteinuria in patients with chronic kidney disease.

METHODSThis multicenter, randomized, and case-controlled clinical trial was conducted among 81 consecutive patients meeting the inclusion criteria. The patients were randomized consecutively to receive TCM treatments according to the syndrome patterns in TCM (spleen and kidney Qi and Yin deficiency, and spleen and kidney Qi and Yang deficiency, n=60) or oral losartan therapy (50 mg/day, n=21) in addition to the basic treatments. All the patients were followed up for 24 weeks to observe the clinical effects.

RESULTSThe patients in TCM group showed a significantly higher overall response rate (93.33%) than those in losartan group (76.20%, P<0.05). The TCM score in the two groups were all decreased at week 24 as compared with baseline (P<0.01 or P<0.05). The TCM scores in both groups decreased significantly after the treatments as compared with the baseline scores (P<0.05). After a 8-week-long treatment, Scr, eGFR and Cys-C, U-Pro/24 h, and MA/Cr all decreased significantly in TCM group (P<0.05) but showed no significant changes in losartan group (P>0.05).

CONCLUSIONSyndrome differentiation-based TCM treatment in addition to basic treatments can produce satisfactory therapeutic effects on proteinuria in patients with chronic kidney disease by improving the clinical symptoms, reducing TCM symptom scores and proteinuria, and protecting the renal functions.
