Objective To explore the expression of interleukin 13(IL-13) mRNA in peripheral blood mononuclear cells (PBMCs) and its association with serum C-reaction protein(CRP) in patients with ulcerative colitis(UC). Methods IL-13 mRNA expression in PBMCs was detected by RT-PCR in patients with UC(21 cases of active UC and 10 cases of quiescent UC)and 20 healthy subjects. At the same time, the serum level of CRP was detected by ELISA. Results The expression level of IL-13 mRNA in PBMCs of patients with active UC was significantly lower than that in PBMCs of patients with quiescent UC and healthy subjects (6.45?1.23 vs 14.72?2.12 or 15.17?2.38,P0.05). The expression level of IL-13 mRNA in PBMCs of active UC patients was negative correlation with serum level of CRP (r=-0.589,P

BACKGROUND: The onset of vascular dementia (VD) is closely related to brain ischemic-hypoxia. Previous research has proved that behavioral disturbance can be obviously attenuated by xingnao qizhi capsule in VD rats; however, it remains unclear whether the improvement of VD is due to the protection on ischemic cells.OBJECTIVE: Pheochromocytoma PC12 cells were cultured in vitro and exposed to Na2S2O4 to induce hypoxia injury. Then serum pharmacological technique was used to investigate the protection of xingnao qizhi drug serum on hypoxia-injured PC12 cells.DESIGN: Randomized controlled study.SETTING: School of Traditional Chinese Medicine of Hebei Medical College.PARTICIPANTS: This study was conduced at the Experimental Animal Laboratory and Cell Culture Laboratory, School of Traditional Chinese Medicine of Hebei Medical College, between June and December 2003.Forty SD rats were randomized into 5 groups, namely serum control group (n=12) and xingnao qizhi serum 25.42, 12.71, 6.35 and 3.18 g/kg groups (n=7). PC12 cell line was purchased form the Cell Center of Chinese Academy of Medical Sciences.serum 25.42, 12.71, 6.35 and 3.18 g/kg groups were exposed through gastric lavage to xingnao qizhi of corresponding dosages (composed of wolfberwhile normal saline was given by gastric lavage to rats in control group in dosage of 10 mL/kg, twice a day at an interval of 12 hours for 3 consecutive days. One hour after the last administration, femoral blood samples were collected when rats were deeply anaesthetized and serum was sepainto 6 groups. Cells in control group were cultured with control serum while in experimental model groups cells were exposed to Na2S2O4 to induce hypoxia injury 1 hour later. Cells in Xingnao Qizhi 25.42, 12.71,6.35 and 3.18 g/kg groups were cultured in 5% drug serum with corresponding dosage of xingnao qizhi drug for 1 hour before being exposed to changes of PC12 cells in the six groups were observed under reversal microscope after exposure to Na2S2O4 for 16 hours; the inhibition rate of lactate dehydrogenase production and PC12 cell injury (MTT method) was calculated for assessing cell activity.nase production and PC12 cell injury.of xingnao qizhi displayed better refraction, with fewer cell fragments that tion: It was 81.6%, 69.6%, 54.4% and 27.8% in xingnao qizhi 25.42,PC12 cell injury: It was 82.9%, 75.6%, 65.9% and 53.7% in Xingnao Qizhi 25.42, 12.71, 6.35 and 3.18 g/kg groups, respectively.CONCLUSION: xingnao qizhi drug serum can markedly attenuate hypoxia injury of PC12 cells in dose-dependant manner, which is presented by strengthened cell activity and decreased lactate dehydrogenase activity.
