ObjectiveTo establish a rat model of nerve damage induced by intrathecal(IT) lidocaine.MethodsFifty-five adult male SD rats weighing 200-220 g were randomly divided into 5 groups (n =11 each):group normal control (group C); group dimethyl sulfoxide (DMSO)-the solvent(group D) and groups IT 5％,10％,15％ lidocaine (groups L5.10.15 ).IT catheter was successfully implanted without complication in groups D,L5,L1o,L15.DMSO,5％,10％ and 15％ lidocaine 20 μl were injected IT in groups D,L5,L10,L15 respectively.Motor dysfunction of hindlimb was assessed and scored (0 =normal,2 =complete block) and paw withdrawal threshold to mechanical stimulation (von Frey filaments) (MWT) and paw withdrawal latency to thermal nociceptive stimulus (TWL) were measured before (baseline) and at 1,2,3,4,5,7 d after IT administration in 8 animals in each group.Three animals in each group were sacrificed at 1 d after IT administration.The lumbar segment (L4-5) was removed for microscopic examination.ResultsThere was no significant difference in motor dysfunction score,MWT and TWL among groups C,D and L5.MWT was significantly increased and TWL prolonged at 1 and 2 d after IT administration in group L10,while in group L15 motor dysfunction score was significantly increased at 1,2 d after IT administration and MWT was significantly increased and TWL prolonged at 1,2,3 d after IT administration.There was significant histologic damage to spinal cord in groups L10 and L15.Conclusion Nerve damage can be induced by IT 10％ lidocaine.

OBJECTIVETo verify the pharmacological hypothesis of prescriptions by studying the targeted distribution of major components in stewed rhubarb in the rat model with acute pancreatitis (AP).

METHODNormal SD rats (control group, n = 5) and the AP model induced with intraperitoneal cerulein (model group, n = 5) were taken as the experimental objects. Rats of the two groups were orally administered with stewed rhubarb granules (20 g x kg(-1)). Their heart, liver, spleen, lung, kidney and pancreas were collected two hours after the administration. Such constituents as emodin, chrysophanol, physcion, rhein and aloe-emodin and their concentrations in each tissue homogenate were detected by high performance liquid chromatography-mass-mass.

RESULTAloe-emodin and physcion in stewed rhubarb whose concentrations in liver and kidney of normal rats were higher than that in pancreatic tissues, while the distribution spectrums and concentrations of the remaining components in pancreatic tissues had no significant difference with that of other organs. The concentrations of emodin, aloe-emodin, rhein and chrysophanol in stewed rhubarb in pancreatic tissues of the AP model group were higher than that in other tissues and organs, while their concentrations in pancreatic, renal and splenic tissues were notably higher than that in the normal group.

CONCLUSIONIn the conditions of AP, effective components in stewed rhubarb show a targeted distribution feature in pancreas, which provides experimental basis for the pharmacological hypothesis of prescriptions.

The growth inhibition and pro-apoptosis effects of dracorhodin perchlorate on human prostate cancer PC-3 cell line were examined. After administration of 10-80 μmol/L dracorhodin perchlorate for 12-48 h, cell viability of PC-3 cells was measured by MTT colorimetry. Cell proliferation ability was detected by colony formation assay. Cellular apoptosis was inspected by acridine orange-ethidium bromide fluorescent staining, Hoechst 33258 fluorescent staining, and flow cytometry (FCM) with annexin V-FITC/propidium iodide dual staining. The results showed that dracorhodin perchlorate inhibited the growth of PC-3 in a dose- and time-dependent manner. IC50 of dracorhodin perchlorate on PC-3 cells at 24 h was 40.18 μmol/L. Cell clone formation rate was decreased by 86% after treatment with 20 μmol/L of dracorhodin perchlorate. Some cells presented the characteristic apoptotic changes. The cellular apoptotic rates induced by 10-40 μmol/L dracorhodin perchlorate for 24 h were 8.43% to 47.71% respectively. It was concluded that dracorhodin perchlorate significantly inhibited the growth of PC-3 cells by suppressing proliferation and inducing apoptosis of the cells.

Objective The comparison of the clinical role of stress-redistribution/reinjection with dual isotopes of 99Tcm-methoxyisobutylisonitrile (MIBI) and 201TI in the detection of myocardial viability.Methods One hundred and sixty patients with clinically suspicious coronary artery disease (CAD) were included.All had intravenous injection with 740 MBq of 99Tcm-MIBI.Pharmacological challenge with dobu-macological challenge with dobutamin,111 MBq of 201Tl Was injected to all.Myocardial SPECT images were performed in all at 10-min (stress) and 3-h (redistribution/rest) after injection.The 201Tl(37 MBq)would be given to those patients with myocardial perfusion defect at stress images by 201Tl and were demon-strated by both 201Tl(redistribution) and 99Tcm-MIBI (rest).Coronary angiography (CAG) Was performed within two weeks.X2-test was used with SAS 6.12.Results Coronary artery abnormalities were found in all with 76 patients had one vessel disease,51 had two and 33 had three.Of the 152 patients who had myo- cardial perfusion defect during stress images,63 had redistribution by both 201TI and 99Tcm-MIBI.5 had re-distribution by 201Tl only.9 had redistribution by 99Tcm-MIBI only,and 75 had no redistribution in 201Tl or 99Tcm-MIBI images.The sensitivity of detection myocardial viability with myocardial SPECT images between 201Tl at redistribution (66.0%,68/103) and 99Tcm-MIBI at rest (69.9%,72/103) were insignificant (x2=O.36.P>0.05).Of the 75 patients who did not have redistribution in 201Tl or 99Tcm-MIBI images.34.7% (26/75)had myocardial perfusion when reinjection of 201Tl.In all,there were eight false negative myocardial perfusion SEPCT images.Three were triple vessel disease,one Was two, three were one, and the other was patent collateral circulation.Conclusions Stress.redistributed/reinjection 201TI myocardial perfusion SPECT imaging is superior to stress 201Tl/rest 99Tcm-MIBI simultaneous dual-isotopic myocardial imaging in the detec-tion of myocanrdial viability.
