Purpose To investigate the effects of oxytocin(OT) and prostaglandins intervention on oxytocin receptor(OTR) expression of primary culture of human myometrial smooth muscle cell.Methods Using respectively oxytocin, prostaglandin E2(PGE2),and prostaglandin F2alpha(PGF2alpha) intervened on human myometrial smooth muscle cell.The expression of OTR mRNA and protein of cell hemogenate was examined.Results The expression of OTR between oxytocin intervention group and untreated group was similar.The expression of OTR in cell was significantly higher in the PGE2 or PGF2alpha intervention group than that in the untreated group.The expression of OTR in cell was significantly higher in the PGE2 and PGF2alpha joint intervention group than that in the untreated group and than that in the PGE2 or PGF2alpha individual intervention group.Conclusion Oxytocin didn′t increse the expression of OTR in human myometrial smooth muscle cell.PGE2 and PGF2alpha incresed the expression of oxytocin receptor in human myometrial smooth muscle cell.Furthermore PGE2 and PGF2alpha joint intervention more significantly increased the expression of oxytocin receptor than PGE2 or PGF2alpha individual intervention in human myometrial smooth muscle cell.

Objective Development of eyeball is visually regulated by messengers that released from the retina, and research demonstrated that retinoic acid (RA) is the only extrinsic biochemical candidate that could act as a growth controller. Present study was designed to evaluate the RA system in retina of guinea pig eye with experimental form deprivation myopia. Methods The form deprivation myopia models were monocularly established in the 24 2-week-old guinea pigs by occluding the lateral eyes using white translucent hemispheres for two weeks, and the fellow eyes were as normal control. Refraction diopter was detected with streak retinoscopy after cycloplegia, and axial length and vitreous depth were calculated with Cinescan A/B ultrasonography before and 2 weeks after experiment. All animals were sacrificed and retina was dissected 2 weeks after experiment. The RA level in retina was delected by High Performance Liquid Chromatography (HPLC). The expressions of RA-binding proteins Ⅰ(CRABP-Ⅰ) and RA receptor-β(RAR-β) protein and mRNA were assayed by Western-blotting and Real-time PCR, respectively. The experiment and use of animals followed the Standard of Association for Research in Vision and Ophthalmology. Results The spherical equivalent refraction was (+ 3. 00 ± 0. 75) D in the model group and (+ 2. 88 ± 0. 67) D in control eyes (t= 0. 672, P ＞ 0. 05), the ocular axial length was (7. 822 ± 0. 083) mm in model group and (7. 791 ±0.073) mm in control eyes before experiment (t = 0. 346, P ＞ 0. 05). In 2 weeks after experiment, the spherical equivalent refraction was (- 3. 82 ± 0. 13) D versus (1. 99 ± 0. 58) D and axial length was (8. 346 ± 0. 047) mm versus (7. 888 ± 0. 042) mm between model eyes and control eyes (t = 8. 376, P ＜ 0. 001; t = 3. 343, P ＜0. 05). No significant difference in the level of RA in retina before and after experiment (1. 394 ±0. 079 μg/g vs 1. 295 ±0. 023 μg/g) (t =0. 897, P ＞0. 05) but obviously elevated after experiment in model eyes compared with control eyes (2. 356 ± 0.098 μg/g vs 1.499 ±0.035 μg/g) (t =4. 934, P ＜0. 01). The expression of CRABP-Ⅰ and RAR-β mirrored these directional changes. Conclusion The RA system in retina is upregulated in the eye of guinea pig with form deprivation myopia. This findings suggests that RA may act as a messenger in the development of experimental myopia.

Temporal and spatial expressions of ?-catenin investigated in the hair follicle and epidermis of the hoof periphery in bovine embryonic development. IHC (immunohistochemical method) was applied to qualitatively detect the temporal and spatial expressions of ?-catenin. ?-catenin was detected in suprabasal, epidermal basal layer, placode, hair bud in early phase(E68～93),and expressed strongly in epidermal basal layer, placode, and hair bud, in suprabasal expressed less strongly; in metaphase(E94～184), ?-catenin was detected in epidermis, hair peg, and in suprabasal, epidermal basal layer, hair follicle bulge, inner root sheath, outer root sheath, follicular infundibulum expressed less strongly; in late phase(E184～225), ?-catenin expressed weakly in epidermal basal layers, while expressed strongly in epidermal keratinocytes. The result suggested that ?-catenin plays an important role in hair follicle morphogenesis in the periphery of bovine hoof in bovine embryos.

ObjectiveTo investigate the diagnostic value of N-terminal pro-brain natriuretic peptide (NT-proBNP) and MB isoenzyme of creatine kinase (CK-MB) for heart failure (HF) in pneumonia children.MethodsThe NT-proBNP and CK-MB were assayed in 132 pneumonia children with HF, 138 pneumonia children without HF and 62 healthy children were recruited into this study. A receiver operating characteristics (ROC) curve and a logistic regression model were employed to assess the diagnostic accuracy of NT-proBNP and CK-MB for HF in pneumonia children.ResultsPneumonia children with HF had higher blood NT-proBNP and CK-MB than those in pneumonia children without HF and healthy controls (P<0.01 for both). Pneumonia children with HF had higher blood NT-proBNP and CK-MB than the pneumonia children without HF. The area under curves (AUCs) of NT-proBNP and CK-MB for HF were 0.85 and 0.72, respectively. The AUC for their combinational usage was 0.87.ConclusionBoth NT-proBNP and CK-MB are effective markers as diagnostic adjuncts for HF in pneumonia children. Combination of NT-proBNP and CK-MB can improve the diagnostic accuracy for HF in pneumonia children.

After the application of associated data in digital library and in library resources integration was described, the necessity of library resources integration was analyzed, the semantic association process of library resources and the problems of library resources in research on semantic association were studied in terms of system construction, technical implementation and discovery algorithm.

Objective To analyse the survival time and related factors of patients with brain stem glioma who received 3DCRT.Methods Thirty-six patients with brain stem tumor were admitted from October 2004 to December 2008 and all received 3D-CRT with the dosage (50-54 Gy,25-30 f,5-6 weeks).During treatment,the patients’ outcomes were analyzed by observing the changes of symptoms,signs and adverse radiotherapy reaction and all of them were followed-up in the next 3 years.The survival data were analyzed by Kaplan-Meire method.Results The median survival time was 9 months in the 23 pediatric patients and 15 months in 13 adult patients.One-,two-and three-year survival rates between pediatric group and the adult group were 43.5 ％ (10/13) vs 76.9 ％ (10/13),26.1％ (6/23) vs 46.2 ％ (6/13),8.7 ％ (2/23) vs 38.5 ％ (5/13).Karnofsky performance scale score at admission (x2 =20.059,P =0.000),tumor site (x2 =17.585,P =0.000),growth pattern (x2 =21.247,P =0.000) were associate with survival time.Conclusion 3DCRT is an effective therapy to brain stem glioma,childhood onset,pontine glioma,diffusion style and Karnofsky performance scale less than 80 are risk factors of poor prognosis.

Objective To compare the efficacy and safety between flumatinib and imatinib in patients with newly diagnosed chronic myeloid leukemia (CML). Methods A multi-center, randomized and parallel comparison clinical trial was conducted in 24 newly diagnosed patients with Philadelphia chromosome-positive CML-chronic phase (Ph+ CML-CP) who were treated by flumatinib 400 mg/d, 600 mg/d or imatinib for 6 cycles (24 weeks). The hematology was evaluated at pre-medication and the 2nd, 4th, 6th, 8th, 10th, 12th, 16th, 20th, 24th week of post-medication. The morphology, cytogenetics and molecular biology were evaluated at pre-medication and 12th, 24th week of post-medication. Results In terms of efficacy, the main molecular remission (MMR) rate of flumatinib 600 mg/d group was higher than that of imatinib group after 24 weeks [44.44 % (4/9) vs. 14.29 % (1/7), P=0.017]. The rate of bcr-ablIS≤10 % in flumatinib 600 mg/d group was significantly higher than that in imatinib group (P=0.002). PK/PD analysis also hinted that patients treated by flumatinib 600 mg/d was more likely to get molecular reaction in the early stage compared with those treated by flumatinib 400 mg/d. In terms of safety, there was no significant difference in grade Ⅲ-Ⅳ of adverse events among flumatinib 400 mg/d group, flumatinib 600 mg/d group and imatinib group (P >0.05). The common adverse events in flumatinib group included skin toxicity, gastrointestinal reactions and diarrhea.There was no heart and cardiovascular toxicity in flumatinib group, and incidence of edema in flumatinib group was lower than that in imatinib group. Conclusions Flumatinib is a safe and effective drug for newly diagnosed patients with Ph+ CML-CP, and 600 mg/d is the appropriate clinical starting dose. Flumatinib and imatinib have similar safety in clinic.

BACKGROUND:Recombinant adeno-associated virus serotype 9 has a high affinity in myocardial tissue, and the expression of recombinant adeno-associated virus serotype 9-enhanced green fluorescent protein (rAAV9-eGFP) in the aorta of atherosclerosis mice is not clear. OBJECTIVE:To explore the optimal time point of rAAV9-eGFP expression in the aorta of atherosclerosis mice. METHODS:Atherosclerosis model was established with high-fat diet in 30 ApoE-/-mice for 16 weeks. Among them, 25 mice were injected with 5.0×1011 vg (virus genomes) rAAV9-eGFP through the tail vein, while the remaining 5 mice were injected with saline, serving as the control group. The virus-transfected mice were kil ed at 14, 21, 28, 35 and 60 days after transfection, and aortic tissue was harvested. The expression of enhanced green fluorescent protein was detected with laser scanning confocal microscope. Western blot assays were used to detect the expression of enhanced green fluorescent protein in aorta. The expression of enhanced green fluorescent protein in vivo was observed and the optimal expression time point was determined. RESULTS AND CONCLUSION:rAAV9-eGFP effectively transfected the aorta of atherosclerosis mice, enhanced green fluorescent protein was expressed in aortic tissue, and the expression intensity increased gradual y with the increasing transfection time. The highest expression level was found at 35 days after transfection and then maintained stable at 60 days. There were significant differences at different time points after transfection (P<0.001). These data indicate that rAAV9-eGFP can be effectively expressed in the aorta of atherosclerosis ApoE-/-mice and rAAV9-eGFP can be regarded as the optimal vector in the treatment of atherosclerosis.
