Phytoene synthase is a rate-limiting enzyme in the pathway of carotenoid biosynthesis.To aim at establishing a transformation of Ginseng callus cells, elevating the nutritive value through encouraging the composition of corresponding carotenoid,taking Ginseng callus cells as acceptor,psy gene were transformed into cells via Agrobacterium-mediated. The factors affecting genetict ransformation were also investigated seperately from concentrations of A.tumefaciens, age of Ginseng callus cells, infection time and co-culture time. PCR,PCR-Southern and RT-PCR analysis from the transferred gene plants proved that psy gene has been transferred into Ginseng callus cells and can be expressed. The content of ?-carotene was increased by an average of 26 times.A base of improving and raising the contents of carotenoid in the Ginseng callus cell was established.

Objective To study the relationship between self-esteem and childhood abuse, life events among male violent adolescent. Methods According to the modified overt aggression scale, juvenile delinquents were divided into violent group (n = 128 )and nonviolent group (n = 118 ). All the participants were investigated by Self-Esteem Scale (SES), Childhood Trauma Questionnaire-28 Item Short Form (CTQ-SF) and Adolescent SelfRating Life Events (ASLEC) and conducted correlation and regression analysis. Results ①Violent group had lower self-esteem scores ( 22.73 ± 3.30 ) than the nonviolent group ( 23.81 ± 3.30, P ＜ 0.05 ). Violent group had higher scores in physical abuse, sexual abuse, total life events, interpersonal relationship, punishment, and other (8.30 ±4.07, 7.23 ±2.26, 54.48 ±18.60, 10.09 ±3.84, 14.43 ±5.87, 4.93 ±3.15, 9.93 ±3.64), compared to the nonviolent group (7.27 ± 3.27, 6.60 ± 2.09, 45.40 ± 18.45, 8.42 ± 4.13, 11.07 ± 5.75, 3.66 ±2.81, 7.84 ±3.66, P＜0. 05). ②The self-esteem was significantly negative correlated with the childhood abuse and life events( r= -0. 143 ～ -0. 358, P＜ 0.01 ) among violent male adolescents. ③The physical abuse and punishment had significant prediction function of 15.6% on self-esteem. Conclusions Violent adolescents have low self-esteem, which is closely related to childhood abuse and adolescent life events.

Background Eicosapentaenoic acid(EPA)function as the critical lipid mediators involved in several biological events in human body and play important role in suppressing the genesis of vascular endothelial growth factor (VEGF),migration and proliferation of vascular endothelial cells.Many ocular diseases were proved to be associated with neovascularization.Objecfive The purpose of this study was to investigate the inhibitory effect of EPA on the proliferation of human umbilical vein endothelial cells (HUVEC) indueed by VEGF. Methods HUVEC strain was cultured and passaged,and difierent concentrations of EPA were added to the medium with and without VEGF.The cultured cells were identified by antiofactor Ⅷ polyclonal antibody.The suppressing role of different concentrations of EPA on the proliferation of VEGF-induced or-uninduced HUVEC was assessed by MTT method.The influence of difierent concentrations of EPA on the cellular cycle of VEGF-induced HUVEC was assayed using flow eytometry.The expression of Flk-1,a receptor of VEGF,in the HUVEC Was detected by immunohistochemistry. Results Cultured HUVEC showed the ftlsiform in shape and presented with the cobblestone-like arrangement with the positive response for Ⅷ factor-related antigen.Various concentrations of EPA showed obviously inhibitory effect on VEGF-induced or-unindueed HUVEC at a dose-dependent manner (F=23.072.P=0.000).The inhibitory ability of EPA on VEGF-induced HUVEC was stronger than VEGF-uninduced HUVEC(F=41.417,P=0.000).In 24,48 and 72 hours,the action of EPA on the proliferation of HUVEC was gradually enhanced with the prolong of time(F=1.495,P=0.236).Cell cycle analysis indicated that EPA arrested VEGF-induced HUVEC in G0/G1 phase.The ratio of HUVEC in G0/G1 phase in EPA group was(75.83±1.56)%,and that in control groups was(68.62±1.44)%,showing a significant difference between them(t=-5.88,P=0.00),and no apoptosis of HUVEC was found in both groups.Flk-1 was strongly expressed in the cellular nucleus and cytoplasm in control group.However,the positive expressing intensity of Flk-1 in the HUVEC weakened,and the positive cell number was evidently less in EPA group. Conclusion EPA can inhibit the proliferation of VEGF induced HUVEC through arresting the synthesis of DNA of HUVEC and downregulate the expression of Flk-1 in HUVEC.These results suggest that EPA might exert an antiangiogenic effect.

Background Researches have showed that the extraocular muscle injection of insulin-like growth factor(IGF) results in the thickness of extraocular muscle and enhancement of contractility,and lack of IGF probably is associated with pathogenesis of strabismus.If extraocular muscle injection of insulin-like growth factor binding protein 4(IGFBP-4),an inhibitor of IGF,can further ensure the effect of IGF is still under-investigation.Objective The aim of this study was to evaluate the effects of IGFBP-4 on the developing extraocular muscle.Methods IGFBP-4 of 2 μl(1 g/L)was injected into superior rectus muscles via supraorbital margin in the left eyes of 24 postnatal l-day-old chickens once every other day for five times,and the equivalent amount of normal saline solution was used in the same way in the fellow eyes as controls.The animals were sacrificed by overdose of anesthesia 2 days after the final injection and 12 animals were randomly selected for the maximal contractility test of superior rectus muscle.The other 12 pieces of superior rectus muscle of the chickens were obtained for the hematoxylin & eosin staining to evaluate the morphology of superior rectus muscle and calculate the myofiber diameter using imaging system.Results The maximal contractility was (1.602 ± 0.080) mN and(1.815±0.O10)mN in the IGFBP-4 injection group and normal saline solution group respectivily,showing a significant difference between the two groups(t =13.65,P＜0.01).The maximal contraction force in cross-sectional area was (95.500 ± 7.420) mN/cm2 in the IGFBP-4 injection group and it was significantly lower than that of the normal saline solution group(101.510±5.220)mN/cm2(t =28.81,P＜0.01).Histological examination showed that thin myofibers were obvious more in the IGFBP-4 injection group than those with saline injection.The mean diameter was (8.7 ± 0.5) μm in the IGFBP-4 injected group,and that of the normal saline group was(9.1 ±0.4) μm,there was no significant difference between them (t =0.75,P =0.46).However,significant differences were found in the number of different diameters of myofibers between the two groups(all at P＜0.05).Conclusions IGF is one of the key nutrition factors in the development of extraocular musele.The extraocular muscle injection of IGFBP-4 may cause the dysfunction and morphologic abnormality of extraocular muscle.

OBJECTIVETo discuss the application of automated DNA image cytometry (ICM) and fluorescence in situ hybridization (FISH) in the diagnosis of urothelial carcinoma of bladder.

METHODSFrom August 2008 to March 2009, 60 volunteers with informed consent were divided into two groups, 40 patients proven as urothelial carcinoma of bladder by pathology and 20 healthy individuals as control. Urine was collected and tested by cytology, ICM and FISH.

RESULTSOverall sensitivity of FISH was significantly higher in detection of malignancy than that of ICM (82.5% vs 62.5%, P < 0.05) and that of urine cytology (82.5% vs 25.0%, P < 0.05), while ICM was more sensitive to diagnose urothelial carcinoma of bladder than urine cytology (62.5% vs 25.0%, P < 0.05). Specificities of urine cytology, ICM and FISH were 100% in diagnosis of urothelial carcinoma of bladder (P > 0.05). Sensitivities of urine cytology, ICM and FISH have no correlation with pathological stage (P > 0.05), but have significant correlation with grade (P < 0.05).

CONCLUSIONSICM and FISH have the same specificity as urine cytology in diagnosis of urothelial carcinoma of bladder, but they have significantly higher sensitivity than urine cytology. FISH has the highest sensitivity among three diagnostic methods. Therefore, FISH may become a newly non-invasive technique for the diagnosis and surveillance of urothelial carcinoma of bladder.
