Objective To investigate the feasibility and efficacy of iliofemoral endovascular therapy for the treatment of chronic ischemia of lower extremities due to arterial atherosclerosis. Methods During the period of September 2005-January 2009 percutaneous endovascular angioplasty and stent implantation were performed in 15 consecutive patients with CTA-proved chronic occlusive iliofemoral artery disease. The patients included 11 males and 4 females with a mean age of (72.1 ± 5.9) years (ranged from 61 to 82 years). Before the procedure, all patients underwent clinical and imaging assessments, including Fontaine classification, ankle-brachial pressure index (ABI), and lower limb computed tomography angiography (CTA). According to the length, morphology and location of the occlusive segment, different types of stents were employed together with pereutaneous transluminal angioplasty (PTA) to treat the occluded lilac or superficial femoral artery. At the end of the procedure, distal angiogram was performed to assess the success of the procedure and to exclude thromboembolism or dissection complications. After PTA, the residual stenosis < 30% and/or pressure gradient < 10 mmHg were defined as technical success. Clinical success was identified when patient's clinical symptoms were improved by one or more grade according to Fontaine classification. Results Technical success was totally achieved in all patients with no occurrence of complication. Recanalization of the occluded artery was performed preferably by retrograde ipsilateral femoral artery approach in 5 patients and by contralateral access using the crossover aorta technique in 10 patients. PTA was performed in all patients after stent release to open the occluded vessel to its normal diameter. The mean length of the lilac arterial segment covered with 8 stents was (7.6 ± 1.4) cm (ranged from 6 cm to 10 cm). The mean diameter ± SD of the iliac stents was 9.5 mm ± 1.4 mm (ranged from 8 mm to 12 mm). The mean length of 5 superficial artery implanted stents was (4.5 ± 1.1) cm (ranged from 4 cm to 6 cm). The mean ABI before treatment and six months after treatment was 0.64 (range 0.41 to 0.89) and 0.76 (range 0.50 to 0.95), respectively. The difference in ABI between pre-interventional and post-interventional procedure was statistically significant (t = -4.64, P < 0.01). Clinical improvements according to Fontaine classification were obtained in all patients, in whom technical success was achieved (100%). Conclusion Endovascular interventional procedure is a safe and effective treatment for iliofemoral arterial occlusive disease due to arterial atherosclerosis. PTA combined with subsequent stent implantation can well improve the patient's quality of life as well as the hemodynamics of lower extremities, which is very important for preserving the diseased limb for a long period of time.

To study the protective effect of Danshen Tongluo capsule on rat hearts in the myocardial infarction (MI) model. After being fed with high fat diets for one month, the SD rats were randomly divided into the sham group and the model group according to the left ventricular ejection fraction (EF). The MI model group was duplicated by ligating coronary artery and then divided into five groups: the model group, the positive control group (model + captopril), the small dose group (model + Danshen Tongluo), the medium dose group (model + Danshen Tongluo) and the high dose group (model + Danshen Tongluo). Four weeks later, changes in myocardium ultra-structure were observed by hemodynamics, cardiac ultrasound and electron microscope. The results showed: (1) All doses of Danshen Tongluo capsule could significantly reduce the left ventricular end diastolic pressure (LVEDP) (P <0.01), increase the maximum internal pressure of the left ventricle (+ dp/dtmax), and lower the drop rate of left ventricular pressure (- dp/dtmax), with statistical significances in medium and high dose groups; (2) The B ultrasound results showed increase in EF and left ventricular shortening fraction (FS) in all dose groups of Danshen Tongluo capsule; (3) The medium dose group showed significant decrease in myocardial infarction index (P <0.01) and injured and fractured myofilament and sarcomere of ischemic myocardium in myocardial ultra-structure; All of Danshen Tongluo capsule-treated groups revealed reduction in myocardial injury and myocardial infraction area. The study preliminarily proves that Danshen Tongluo capsule can improve hemodynamic function, and has a protective effect on myocardial ischemia.

This study was aimed to explore the expression of 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2) in 3 different lymphoblastic cell lines with relation to their glucocorticoid (GC) sensitivity. The 11β-HSD2 expressions in acute lymphoblastic leukemia Jurkat cells, lymphoma Daudi and Raji cells, and peripheral blood T cells of a healthy volunteer were analyzed by real time PCR and Western blot. Glucocorticoid (GC)-induced apoptosis in 3 different cell lines was detected by flow cytometry. Cell growth in Jurkat cells treated with cortisol was analyzed by trypan blue dye exclusion. Flow cytometry was performed to observe GC-induced apoptosis in Jurkat cells treated by combination of GC with 11β-HSD2 inhibition 18β-glycyrrhetinic acid (18β-GA). The results demonstrated that 11β-HSD2 highly expressed in Jurkat cells, but not in Daudi, Raji cells and normal blood T cells. Compared to Daudi and Raji cells, Jurkat cells were more resistant to GC-induced apoptosis. Furthermore, the inhibition of 11β-HSD2 by 18β-GA resulted in increased cellular sensitivity to GC as shown by elevated induction of apoptosis. it is concluded that 11β-HSD2 is at least partly responsible for GC resistance in Jurkat cells. 11β-HSD2 may be a potential target for reduction of GC-resistance in therapeutic applications.

OBJECTIVETo access the feasibility of employing metabonomics method in clinical studies. This pilot study intends to introduce nuclear magnetic resonance (NMR)-based metabonomics method to elucidate the metabolism of non-syndromic cleft lip and/or palate (NSCLP) patients.

METHODSHigh-resolution 1H NMR spectroscopy was performed on blood plasma obtained from NSCLP and non-malformed children. All signal of 1H NMR spectra were recognized within MESTRE-v4.7, and the 1H NMR spectra integration into bins (or buckets) across the spectral regions of bin 0.04 was performed automatically in MESTRE-v4.7. The resulting data matrix was further analyzed, which was performed by SIMCA-P 11.0. The principal component analysis (PCA) was applied to the centered data to explore any clustering behavior of the samples.

RESULTSThe results demonstrated the metabonomic difference in plasma between NSCLP and non-malformed children at least lies in 3-Hydroxybutyrate gamma-CH3, arginine and valine. Arginine excretion appeared to be higher in the non-malformed children population, while NSCLP population excreted higher concentrations of 3-Hydroxybutyrate gamma-CH3 and valine.

CONCLUSIONThe present study clearly demonstrated the great potential of the NMR-based metabonomics approach in elucidating the NSCLP plasma metabolism and the possibility of application in clinic diagnosis and screening.

To compare the growth characteristics of non-hematopoietic adult stem cells (NASC) derived from rat fetal blood and rat bone marrow in vitro, and to study the differentiation of these stem cells into neuron-like cells in vitro, the fetal blood of pregnant rats and bone marrow of adult rats were sterilely collected; mononuclear cells (MNC) were isolated by using standard Ficoll-hypague techniques and then cultured in DMEM/LG containing 10% fetal bovine serum (FBS). The acquired NASCs were subcultured for passage. The immunophenotype of NASCs was detected by flow cytometry. The expanded NASCs were induced to differentiate into neurons-like cells by beta-mercaptoethanol (beta-ME), dimethylsulfoxide (DMSO), butylated hydroxyanisole (BHA). The specific markers of these neuron-like cells were detected by immunocytochemistry. The results showed that two kinds of subcultured NASCs showed homogeneous spindle-shaped and expressed antigens CD44 and CD54, but did not expressed CD11b and CD45. The both induced cells were similar to neuron in morphology and were positive for nestin and neuron-specific enolase (NSE), but negative for glial fibrillary acidic protein (GFAP). It is concluded that no significant difference of NASCs derived from pregnant rat fetal blood and adult rat bone marrow found in cell morphology and biological characteristics. NASCs of both origins can be induced to differentiate into neuron-like cells, so fetal blood can be regarded as another resource of NASC.
