Parkinson's disease (PD) is a common neurodegenerative disorder associated with aging.Recent studies in animal models of PD and analyses of brain specimen from PD patients revealed an increase in the level and activity of the non-receptor tyrosine kinase Abelson (c-Abl) in dopaminergic neurons with phosphorylation of protein substrates,such as a-synuclein and the E3 ubiquitin ligase, Parkin.Most significantly inhibition of c-Abl kinase activity by small molecular compounds used in the clinic to treat human leukemia has shown promising neuroprotective effects in cell and animal models of PD.This has raised hope that similar beneficial outcome may also be observed in the treatment of PD patients by using c-Abl inhibitors.Here we highlight the background for the current optimism, reviewing c-Abl and its relationship to pathophysiological pathways prevailing in PD, as well as discussing issues related to the pharmacology and safety of current c-Abl inhibitors.Clearly more rigorously controlled and well-designed trials are needed before the c-Abl inhibitors can be used in the neuroclinic to possibly benefit an increasing number of PD patients.

OBJECTIVE:To investigate the effects,prognosis and safery of recombinant human brain natriuretic peptide on the treatment of patients with acute decompensated heart failure. METHODS:90 inpatients with acute decompensated heart failure were divided into observation group and control group according to the use of recombinant human brain natriuretic peptide or not,with 45 cases in each group. Control group received rountine anti-heart failure therapy and intravenous dripping of Nitroglycerin injection at 20 μg/min continuously for 72 h. Observation group was additionally given Lyohilized recombinant human brain natriuretic peptide with initial loading amount of 1.5 μg/kg,iv,then intravenous dropping at 0.007 5 μg/(kg·min)continuously for 72 h,on the basis of control group. Hemodynamic parameters,brain natriuretic peptide level,the difference of liquid intake and output,dyspnea,lung rales,systemic edema,the improvement of cardiac function were observed and compared between 2 groups before and after treat-ment as well as re-hospitalization rate and surriral rate 30 d after medication,the occarrence of ADR. RESULTS:After treatment, left ventricular ejection fraction of observation group was significantly higher than that of control group,and central venous pressure and brain natriuretic peptide level were lower than those of control group,with statistically significance (P<0.05). The difference of liquid intake and output after treatment was (1 171.60 ± 444.80)ml in observation group and (822.30 ± 268.40)ml in control group,with statistical significance between 2 groups(P<0.05). After treatment,the scores of dyspnea,lung rales and systemic ede-ma were decreased in 2 groups;the improvement of observation group was significantly better than that of control group,with statis-tical significance(P<0.05). Total effective rates of observation group and control group were 95.56% and 82.22%;re-hospitaliza-tion rates 30 d after medication were 17.78%and 26.67%;survival rates 30 d after medication were 88.89%and 75.56%,with sta-tistical significance between 2 groups (P<0.05). There was no statistical significanse in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:Recombinant human brain natriuretic peptide can significantly improve hemodynamic parameters and heart function of patients with acute decompensated heart failure,and effectively relieve dyspnea,lung rales and systemic edema. It is better than routine treatment in prognosis with good safety.

Objective To build a nomogram of normal fetal lung volumes (left,right and total)throughout gestational age estimated by 3-dimensional ultrasonography.Methods Left and right lung volumes were assessed in 324 normal and singleton fetuses of gestational age 16-37 weeks by 3-dimensional ultrasonography using the technique of virtual organ computer-aided analysis(VOCAL) at a rotational step of 30 degrees.The relationships between left,right,and total lung volumes,and gestational age were assessed by correlation and regression analysis.Results The right,left,and total lung volumes were highly correlated with gestational age (P＜0.001),and the correlation coefficient was 0.966,0.973 and 0.990respectively.The best-fit exponential curve regression equations of left lung volume was:y=0.207exp~(0.143X);right lung volume was:y=0.301 exp~(0.14X);total lung volume was:y=0.508 exp~(0.142X).Conclusions A nomogram of fetal lung volumes estimated by 3-dimensional ultrasonography from 16 to 37weeks gestation is described,and reference values may be useful for the prenatal prediction of pulmonary hypoplasia.

Objective To investigate the correlation between phosphatidylinositol 3 kinase (PI3-kinase) and the pathogenesis of psoriasis. Methods By dot hybridization, in situ hybridization and immunohistochemistry, expression of PI3 kinase was observed in twelve psoriatic and five normal epidermis. Results In psoriatic epidermis, expression of PI3 kinase gene and protein was elevated obviously compared with that of normal skin. Conclusion PI3 kinase may be closely associated with hyperproliferation of psoriatic keratinocytes.

Objective To evaluate the efficacy and safety of ultrasound-guided percutaneous umbilical blood sampling. Methods Eight hundred and seventy-two pregnancies with proper indications underwent ultrasound-guided percutaneous umbilical sampling. The data of each procedure were prospectively collected and subsequently analyzed for successful rate and pregnancy outcomes. Results Of 872 ultrasound-guided percutaneous umbilical sampling, 62.7% were done successfully at the first attempt, 36.0% were done successfully by two to four attempts. 31.4% fetuses had mild procedure-related complications and 0.3% fetuses had severe complications. Conclusion We should improve the efficacy and safety of ultrasound-guided percutaneous umbilical sampling and make it a correct, safe and effective procedure for prenatal diagnosis.

Objective To screen the microsatellites with low occurrence rate of stutter band and establish the effective bovine STR typing system.Methods The tetranucleotide STR loci in bovine genome were searched with Tandem Repeat Finder software.Primers were designed and used to amplify these candidate loci and the PCR products were separated with electrophoresis.DNA samples from 100 head of unrelated cattle were typed.Results Among these candidate loci,6 bovine tetranucleotide STR loci showed high polymorphism,and their CDP and CPE value were 0.99995 and 0.859591 respectively.Conclusion The 6 bovine tetranucleotide STR loci can be used for bovine identification and parentage testing.

Objective To study the expression of insulin like growth factor binding proteins 3 (IGFBP-3) during inhi-bition of resveratrol (Res) on cell proliferation. Methods The inhibitory effect of Res on BGC-823 cells was determined by MTT method; Real-time qRT-PCR and western blot were applied to detect the expression of IGFBP-3 in Res-treated BGC-823 cells. In addition, cytometry was used to determine the proliferation and apoptosis of Res-treated BGC-823 after knockdown of IG-FBP-3 by siRNA. Results Upon Res (20,40, 80 and 160 μmol · L-1 ) treatment,the viability of BGC-823 cells was (82. 35±10. 65)% ,(74. 30±12. 36)% ,(62. 80±14. 66)% and (50. 75±11. 14)% , respectively. The mRNA and protein ex-pression of IGFBP-3 elevated as high as 2. 96-fold compared to the control group (P<0. 05). The cell viability of BGC-823 cells with IGFBP-3 knockdown was significantly higher than that of the wild type ( P < 0. 05 ) only at high Res concentration (160 μmol·L-1 ). Meanwhile,IGFBP-3 knockdown led to a significant decrease on cell apoptotic rate by Res (160 μmol·L-1 ) [(20. 13±9. 12)% vs (35. 48±11. 12)% ,P<0. 05)]. Conclusion Res can inhibit BGC-823 cell proliferation and promote cell apoptosis, the underlying mechanism of which may be related to the overexpression of IGFBP-3 in BGC-823 cells.

Objective To approach the relationship of the expression of hepatocyte growth factor (HGF)/c-met and clinical characteristics of patients with ovarian tumor. Methods Immunohistochemistry (SABC)was used to detect the expressions of HGF and c-met in different pathology group with ovarian cancer. Results HGF positive cells are chromatosised to yellow and take strong expression in the ovarian cancer tissue. C-met takes strong expression in epithelial cell and amply-chromatosis in interstitial cell. HGF and c-met have significant deviation in ovarian tumors, commissurotome tumors and benign tumors (P
