OBJECTIVETo investigate the impact of adding folic acid, vitamin B(12) and probucol to standard antihypertensive medication on plasma homocysteine (Hcy) and asymmetric dimethylarginine (ADMA), serum NO and eNOS of essential hypertensive patients.

METHODA total of 120 patients with hypertension were randomly divided to three groups (n = 40 each): group 1 (standard medication), group 2 (adding folic acid 5 mg/day and vitamin B(12) 500 µg twice daily) and group 3 (adding folic acid 5 mg/day and vitamin B(12) 500 µg twice daily and probucol 500 mg twice daily). Plasma Hcy and ADMA, serum NO and eNOS levels were observed at baseline, 2 and 12 weeks after various therapy.

RESULTSIn group 1, concentrations of plasma Hcy [(23.06 ± 14.15) µmol/L, (23.67 ± 12.31) µmol/L, (23.25 ± 11.64) µmol/L], ADMA [(0.21 ± 0.12) µmol/L, (0.23 ± 0.13) µmol/L, (0.21 ± 0.09) µmol/L] and serum NO [(64.14 ± 15.07) µmol/L, (65.29 ± 15.04) µmol/L, (65.32 ± 13.58) µmol/L], eNOS [(20.02 ± 4.50) µg/L, (20.79 ± 4.03) µg/L, (19.82 ± 5.70) µg/L] remained unchanged during the 12 weeks therapy (all P > 0.05). In group 2, concentrations of plasma Hcy [(12.54 ± 6.49) µmol/L] and ADMA[(0.18 ± 0.07) µmol/L] were significantly decreased after the treatment of 12 weeks than the treatment baseline value [(21.51 ± 7.82) µmol/L, (0.20 ± 0.12) µmol/L] and 2 weeks value[(19.38 ± 8.14) µmol/L, (0.21 ± 0.12) µmol/L], however the concentrations of serum NO and eNOS showed contrary results of the Hcy and ADMA's. (all P < 0.05). In group 3, similar changes occurred at 2 weeks after therapy (P < 0.05 2 weeks vs. baseline and 12 weeks vs. 2 weeks). Plasma ADMA level was positively correlated with Hcy at baseline (r = 0.546, P < 0.05).

CONCLUSIONSSupplementation of folic acid, VitB(12) and/or probucol helps to improve endothelial function and reduce plasma Hcy and ADMA levels in patients with hypertension.

Objective To explore the relationship of vascular endothelial growth factor(VEGF),IFN-? and IL-4 and effect of Bude-sonide on their in asthmatic rats.Methods Thirty-six male SD rats were randomly divided into 3 groups:asthma group,Budesonide-treatment group and control group.On the first day of the experiment and the 8th day,the rat models of the asthma group and Budesonid treatment group were allergized by the OVA/Al(OH)3 through intraperitoneal injection,respectively.And starting from the 15th day,they were challenged by the OVA through atomization for 2 weeks.Control group was allergized and challenged by NS atomization.Budesonid treatment group was interfered in Budesonide inhalation before suscitation in 0.5 h.After 12 h the same inhal done was again in Budesonide group.Twenty-four hours after the last challenge,the rats in 3 groups were sacrificed,and blood and bronchoalveolar lavage fluid(BALF) were collected.The concentrations of IL-4,IFN-? and VEGF in serum and BALF were measured by enzyme-linked immunosorbent assay.Results The concentrations of IL-4 in serum and BALF in asthma group and Budesonide treatment group were significantly increased than those in control group(P

OBJECTIVETo investigate the clinical effect of penile augmentation with superficial fascia retrocession.

METHODSThe first annular incision line was designed, reserving the inner plate 0.5 -0.8 cm. The second annular incision line was determined, according to the length of penile erection. The skin tissue between the double loops was stripped, reserving the superficial fascia and the superficial dorsal veins. Before the closure of two annual incision with no tension, the superficial fascia tissue was pushed proximally and fixed sectionally to augment penis.

RESULTSFrom Jun 2009 to Jun 2011, 60 patients with redundant prepuce or phimosis were treated with this method. During 3 to 12 months follow-up, the postoperative penile perimeter increased significantly. The glans were exposed and the prepuce looked smooth. The function of the penis maintained undamaged.

CONCLUSIONSThe penile augmentation with superficial fascia retrocession can make full use of autologous tissue to augment penis, meanwhile, redundant prepuce can be resected. It is very practical for clinical application.

OBJECTIVETo explore the possibility of using an endovascular microcoil as a gene delivery system.

METHODSAnti-adenoviral monoclonal antibodies were covalently attached to the collagen-coated surface of platinum microcoil. These antibodies were used to tether adenovirus encoding green fluorescent protein (Ad-GFP). Cell culture studies with rat arterial smooth muscle cells (A10) assessed transduction on or near the coil. Platinum coils coated with Ad-GFP were implanted into the ligated common carotid artery (CCA) of adult rats in a model of arterial stasis and pressurization. After 7 days, CCA segments were harvested, and coils were removed for histopathology and GFP expression studies, while organs were evaluated by polymerase chain reaction to assess viral biodistribution.

RESULTSIn cell culture studies, GFP-positive smooth muscle cells were detected only on the platinum coil surface. After 7 days, GFP was detected on the harvested platinum coil and in the organizing thrombus within the CCA according to fluorescence microscopy and immunohistochemistry. Morphometric analyses revealed that (13.3 +/- 2.0)% of cells within the organized thrombus were transduced with Ad-GFP via the gene delivery system. Ad-GFP was not detectable by polymerase chain reaction in lung, liver, or kidney.

CONCLUSIONSGene delivery endovascular microcoils represents an interventional device-based gene therapy system that can serve as a suitable platform for either single or multiple gene therapy vectors.

OBJECTIVETo identify antigens which may help evaluate the therapeutic effect of angiostrongyliasis from adult worm antigen of Angiostrongylus cantonensis.

METHODSThe adult worm antigens of A. cantonensis were analyzed by Western blotting with the sera of rats infected with A. cantonensis before and after treatment. The sera of rats were tested by enzyme-linked immunosorbent assay (ELISA).

RESULTSThe antigens with relative molecular mass between 38,000 and 78,000 reacted not only with the sera of rats before treatment, but also with that after treatment. The antigens with M(r) between 190,000 and 17,000 reacted with the sera of rats before treatment but not with that after treatment; those with M(r) between 32,000 and 24,000 antigens strongly reacted with the former, but the reaction became much weakened with the latter. The AC32-IgG antibody appeared earlier than the AC-IgG, and disappeared rapidly after treatment. Six of the 10 treated rats became negative for AC-IgG as found by ELISA.

CONCLUSIONThe antigens of adult worm antigen of A. cantonensis with M(r) of 190,000, 32,000, 24,000, 17,000 and 16,000 may serve as candidate antigens for therapeutic effect evaluation of angiostrongyliasis.

OBJECTIVETo establish a novel Myc gene transgenic mouse model for spontaneously forming B-lymphoma and assessing its tumorigenesis potential.

METHODSFreshly isolated hematopoietic progenitor cells served as the target for Myc gene transfer mediated by a retrovirus vector. These cells were engrafted into C57BL/6 mice with (60)Co-gamma ray radiation in advance. Tumor latency was measured and the tumor loaded mice were followed for survival time. Tumor was identified with histology and immunostaining. The exogenous Myc gene was detected by Western blot (in liver, spleen, tumor tissue) and flow cytometry (FCM) \[in bone marrow (BM)\].

RESULTSMice BM-infected with mutant Myc gene more readily gave rise to B-cell lymphomas than those infected with wild type Myc gene did Myc gene was expressed highly in BM and tumor tissues but not in liver and spleen.

CONCLUSIONOur model will be a tool in assessing the transforming potential of Myc mutants and in studying cooperation between Myc and other oncogenes. Mutant Myc is more effective than wild-type Myc in promoting B cell lymphomagenesis in mice.

OBJECTIVETo study the effect of RAR-beta transfection plus treatment with the corresponding ligand ATRA on the proliferation and phenotype of platelet-derived growth factor (PDGF)-activated hepatic stellate cells (HSC).

METHODSPDGF-activated hepatic stellate cells of rats were transfected with eukaryotic expression vector pCMV-script-RAR-beta, which was verified by western blot. The proliferation of transfected HSC was assayed by BrdU incorporation as well as MTT methods. Their phenotype (alpha-SMA and desmin) was observed by immunocytochemistry assay with image analysis and RAR-beta protein expression was detected by western blot.

RESULTSTransfection of RAR-beta gene and treatment with ligand ATRA could increase the expression of RAR-beta protein for at least 144h and inhibit the proliferation and the expression of alpha-SMA and desmin in PDGF-activated HSC. Significant statistical differences were perceived comparing with sham-transfected, only-PDGF treated, non-ligand treated and irrelevant ligand-treated HSC.

CONCLUSIONSTransfected with RAR-beta gene as well as using related ligand ATRA could suppress the proliferation and reverse the activation phenotype of activated HSC.
