Objective:To study the effect of interleukin-18 on transdifferentiation in renal tubular epithelial cells(TECs).Methods:Human proximal tubular epithelial cell line(HK-2) was cultured in vitro.TECs were exposed to different concentrations(0,0.1,1,10 and 100 ng/ml) of IL-18 for 24,48 and 72 hours.At the end of each incubation,the expressions of the ?-SMA and TGF-?_1 mRNA were assessed by RT-PCR,the rate of ?-SMA expressing TECs was assessed by immunocytochemistry,and the expression of the ?-SMA protein was assessed by Western blotting.Results:(1)The expressions of ?-SMA and TGF-?_1 mRNA were increased significantly by a dose- and time-dependent manner when TECs were exposed to IL-18(P

Objective To study the effects of panax notoginseng saponins (PNS)on rat superficial renal medulla cells after femoral fracture and to discuss the protective role of PNS in renal injury after fracture. Methods We divided 102 Wistar rats randomly into simple fracture group (n =36),fracture and medication group (n =36)and normal control group (n =30).In the former two groups 6 rats were respectively executed at 1,6,12, 24,36,48 h after fracture modeling,while 5 rats in normal control group were executed at the corresponding time points.Regular HE staining was used to observe pathological changes and TUNEL was used for apoptotic cells.And immunohistochemistry and in situ hybridization were used to detect the expressions of Bcl-2 and Bax in superficial renal medulla tissues.Results In simple fracture group,mild granular degeneration could be seen in renal tubular epithelial cells of superficial renal medulla and the interstitial small vessels were slightly expanded and congested. Compared with simple fracture group,the lesions were slighter in fracture and medication group.In simple fracture group,Bcl-2 and Bcl-2 mRNA expressions were significantly higher than those in normal control group at 1 -36 h (P <0.01).Bax expression was higher than that in normal control group at 12-36 h (P <0.01),and Bax mRNA expression was higher than that in normal control group after 6 h after fracture (P < 0.01 ).In fracture and medication group,Bcl-2 expression was obviously higher than that in simple fracture group at 1 h (P <0.01),and Bcl-2 mRNA expression was higher than that in simple fracture group at 1 -48 h (P <0.01).Bax and Bax mRNA expressions were both lower than those in simple fracture group at 1 - 48 h (P < 0.01 ).Conclusion Fracture trauma has significant influences on protein expression and mRNA transcription of Bcl-2 and Bax in superficial renal medulla.PNS can upregulate anti-apoptosis gene Bcl-2 and downregulate pro-apoptosis gene Bax,thus playing the role of inhibiting tissue cell apoptosis.

Objective To optimize conditions for extraction of alkaloids from Evodia rutaecarpa by means of 732 cation exchange resin and performe its anti-breast cancer bioactivity.Methods The optimum processing route on extraction of alkaloids from Evodia rutaecarpa was investigated by means of 732 cation exchange resin.The performance of 732 cation exchange resin was compared with tranditonal process ( aqueous extraction-ethanol precipitation in extraction-purification process).The alkaloid reagent-potassium mercuric iodide test and MTT test were performed on the crudes.Results Compared with traditional purification process, it was much better to use 732 cation exchange resin approach for extraction of alkaloids from Evodia rutaecarp with high yield(16.81%) The best eluent should be saturated brine with excellent purification.No obvious correlations were found between the toxin of breast cancer cell and concentration of total alkaloids.When the concentration of total alkaloids was 50μmol/mL, cellular survival rate was 68%afterward 24 h.When the concentration of total alkaloids comes to 100 μmol/mL and 150 μmol/mL, cellular survival rates were slightly decreased by 66% and 60%.Conclusion 732 cation exchange resin performes much higher than traditional process in purification of total alkaloids extracted from Evodia rutaecarpa.Simultaneously, the extracted total alkaloids showe remarkable inhibition in breast cancer cell.

Objective To investigate the effect of electro-acupuncture at Guanyuanshu, Xinshu, Neiguan points on cardiac function after acute myocardial ischemia in rabbits. Methods A total of 36 rabbits were randomly divided into a control group, a model group and a treatment group. Acute myocardial ischemia was induced with Jugular vein injection of pituitrin. At 10 min before modeling, 1 hour and 1 week after modeling, the levels of malondialdehyde (MDA) and creatine kinase(CK) were determined respectively, the cardiac function was assessed as the maximum rate of left ventricular pressure rise(dp/dtmax)and the peak left ventricular pressure (LVSP). Results After 1 week of treatment, the serum levels of CK and MDA in the treatment group reduced significantly(120.21±10.67 U/L, 21.35±2.04 mmol/L], compared to the model group (162.37±13.21 U/L, 30.13±2.75 mmol/L) (all P<0.05);the dp/dtmax and LVSP decreased percentage in the treatment group (20%±2.43%, 7.22%±0.97%) decrease significantly compared to the model group (31.5%± 4.14%, 12.19%±2.21%) (all P<0.05). Conclusion Electro-acupuncture of Guanyuanshu, Xinshu, Neiguan acupoints can significantly improve cardiac function after acute myocardial ischemia and protect against acute myocardial ischemia in rabbits.
