OBJECTIVETo investigate the antithrombotic effects and its molecular mechanisms of prazosin combined with anisodamine (Ani).

METHODSIsolated rat tail artery rings model was employed to evaluate the vasodilative effects of drugs, mice tail thrombosis model induced by carrageenan was used to study the antithrombotic effects and its molecular mechanisms of the drug composition.

RESULTSAmong alpha1-adrenoreceptor antagonists, prazosin(Pra) had the greatest relaxation rate, which was (82.6 +/- 8.9)%, and the EC50 value was 0.44 micromol/L. The drug composition of anisodamine and prazosin of different doses could decrease the length of the tail thrombosis from (24.6 +/- 4.6)mm to (6.9 +/- 2.7)mm, and the rate of thrombosis was decreased from 86.6% to 50.0%. The drug composition could prolong the prothrombin time (PT) distinctively, but it had no effect on the activated partial thromboplastin time (APTT). It also could restrain the decrease of serum levels of tissue plasminogen activator (t-PA) and 6- Keto -PGF1alpha as well as the increase of type-1 plasminogen activator inhibitor (PAI-1) and thromboxane B2 (TXB2) in the mice.

CONCLUSIONThe drug composition formed by anisodamine and prazosin has good effects of relaxing extremities tiny blood vessels and it can fight against thrombosis, its antithrombotic mechanisms may be related to the influence of the extrinsic coagulation pathway, inhibition of platelet activation functions and the promotion of fibrinolysis function.

Purpose To investigate the value of MRI T2 mapping imaging in diagnosis of lumbar intervertebral disc degenerative (IVDD).Materials and Methods A prospective study was performed on 100 patients who underwent 1.5T MRI examination because of lumbar and back pain from October 2013 to December 2015 at the Fifth People's Hospital of Shanghai,Fudan University.The MRI examinations included conventional sagittal T1WI and T2WI,axial T2WI and median sagittal T2 mapping imaging.According to Pfirrmann standard,475 lumbar intervertebral discs were graded.T2 values of nucleus pulposus (NP) and annulus fibrosus (AF) of anteriority and posterior with different grades were measured and compared.The correlations between T2 value,age and grade were further analyzed.30 patients were selected and underwent a second MR examination after half a year,and the difference of T2 values between the two MR examinations were compared.Results Except for grade Ⅳ and grade Ⅴ,the differences of T2 values of NP between the other grades of lumbar intervertebral discs were statistically significant (P＜0.05).T2 values of NP were negatively correlated with the grades (r=-0.77).There were no significant differences in T2 values of NP and AF of anteriority and posterior in 30 patients with back pain between the two MR measurements of half year interval (P＞0.05).Conclusion T2 mapping imaging can quantitatively assess the degree of IVDD,especially T2 values of NP can reflect the differences of IVDD with grade Ⅰ-Ⅳ,so it can provide the imaging evidence for the diagnosis of IVDD.

Objective To investigate the role of astrocytes activation in post herpetic neuralgia (PHN). Methods The kunming mice (20-25 g) were used in this study. Resiniferatoxin was injected into the peritoneal cavity.Immunofuorescence was used to detect the activation of astrocytes , mechanical paw withdrawal threshold (MWT)and thermal withdrawal latency (TWL) were used to assay the mechanical allodynia and thermal hyperalgesia, respectively. Fluorocitrate, an inhibitor of astrocytes was intrathecally (i.t.) or intraperitonealy (i. p.) injected into the mice. Results Compared with the vehicle group, MWT was decreased, and TWL was increased significantly in the RTX group. Pre-treatments of fluorocitrate (Fc, i.t.,or i.p.) inhibited the decrease of MWT. Conclusion The activation of astrocytes mediates the post herpetic neuralgia.
