Objective To assess the clinical application of contrast-enhanced MR angiography using three-dimensional(3D)time-resolved imaging of contrast kinetics(CE-MRA 3D-TRICKS).Methods TRICKS is a high temporal resolution(2—6s)MR angiographic technique using a short TR(2.8— 4.0 ms)and TE(0.9—1.3 ms),partial echo sampling and the central part of the k-space being updated more frequently than the peripheral part of the k-space.Pre-contrast mask 3D images are first acquired and 15--20 sequential 3D images following bolus injection of Gd-DTPA are then acquired.Results Thirty patients underwent contrast-enhanced MR angiography using TRICKS.Twelve vertebral arteries were well displayed on TRICKS.Seven of them showed normal,bilateral vertebral artery stenosis was shown in 1 case, and unilateral vertebral artery stenosis was shown in 4 wth aecompaning ipsilateral carotid artery bifurcation stenosis in one case.Bilateral renal artery showed normal in 4 cases,and the artery in transplanted kidney showed normal in one case and stenosis in another case.The cerebral artery showed normal in 2 cases, sagittal sinus thrombosis was detected in one case and intracranial arteriovenous malformation in one case. Pulmonary artery displayed normal in 3 cases,pulmonary artery thrombosis was seen in one case and pulmonary sequestration's abnormal feeding artery and draining vein was revealed in one case.The feeding artery in left lower limb fibrolipoma was showed in one case.The radial-ulnar artery artificial fistula stenosis was seen in one case,and left antebrachium hemangioma was showed in one case.Conclusion TRICKS can clearly delineate the whole body vascular system and can reveal any vascular abnormality.It is convenient and with high successful rate,which make it the first method of choice in displaying vascular abnormality.

Objective To study the immunologic and pathologic features of an accelerated rejection model of renal allotransplantation in presensitized monkeys.Methods The accelerated rejection model of renal allotransplantation was established in presensitized monkeys,which received donor skin transplantation in advance(n=3).The changes of donor specific antibody(DSA)levels in the recipient monkeys before/after skin and kidney transplantation were measured.The kidney grafts were examined for routine pathology,antibody and complement depositions,various lymphocyte subsets infiltration by HE staining,immunofluorescence,or immunohistochemistry.Results All renal allografts in 3 presensitized monkeys developed accelerated rejection within 4 days.In 2 presentized monkeys,the levels of DSA and their mediated complement-dependent cytotoxicity(CDC)were significantly increased after skin transplantation,and further markedly elevated at the time of kidney graft rejection.In the rejected renal grafts,massive C3,C4,C5b-9 and IgG deposits with few lymphocytes infiltration were found.Typical pathologic changes included severe arterionecrosis,thrombosis,interstitial hemorrhage,and infiltration of neutrophils.In the rest one presentized monkey,the levels of DSA and CDC were only marginally increased,and the pathological changes of the rejected renal graft were characterized mainly by the injury of renal tubules.Conclusion Presensitization by donor skin transplantation could elevate the levels of DSA and CDC in recipient monkeys,which resulted in severe antibody-mediated acute humoral rejection in most of the following renal transplants.

OBJECTIVETo determine the equilibrium solubility of pulchinenosiden D in different solvents and its n-octanol/water partition coefficients.

METHODCombining shaking flask method and high performance liquid chromatography (HPLC) to detect the n-octanol/water partition coefficients of pulchinenosiden D, the equilibrium solubility of pulchinenosiden D in six organic solvents and different pH buffer solution were determined by HPLC analysis.

RESULTn-Octanol/water partition coefficients of pulchinenosiden D in different pH were greater than zero, the equilibrium solubility of pulchinenosiden D was increased with increase the pH of the buffer solution. The maximum equilibrium solubility of pulchinenosiden D was 255.89 g x L(-1) in methanol, and minimum equilibrium solubility of pulchinenosiden D was 0.20 g x L(-1) in acetonitrile.

CONCLUSIONUnder gastrointestinal physiological conditions, pulchinenosiden D exists in molecular state and it has good absorption but poor water-solubility, so increasing the dissolution rate of pulchinenosiden D may enhance its bioavailability.
