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 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 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 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 Rereach into the pharmaceutical mechnisms of Ganzhixiao Granule which is used to treat fatty liver. Method Build up fatty cirrhosis-rat models by feeding with high-fat food and alcohol. Contract with Dongbaogantai and observe the influence of Ganzhixiao granule on SOD, MDA and the liver function ferment. Result In the group of Ganzhixiao, the activeness of the liver’s SOD can be increased, while the content of MDA and the activeness of ALT and AST can be decreased, that is much better than Dongbaogantai. Conclusion Ganzhixiao granule has strong effect on fatty cirrhosis, and its mechanism may be concerned with the rat’s liver cell membrane and restraining damaging kuffer cell cytokine.

Objective Through testing the immune functions of SD rats in spring and autumn, the internal mechanisms that lung corresponding with the autumn of TCM were explored, in order to provide the experimental evidence for the pathological and physiological mechanisms of respiratory system seasonal diseases. Method The pineal extirpating rat model was employed, and the indexes of spleen and thymus gland and the phagocytosis function of alveolar macrophage were observed at vernal equinox and autumnal equinox respectively. Result The indexes of spleen and thymus in the normal group and the false operation group at autumnal equinox were significantly lower than those at vernal equinox (P

Objective To establish the quality standard for Xuanshi Texiao Yaoshui(mainly composed of Radix Sophorae Flavescentis,Cortex Pseudolaricis,etc).Methods Radix Sophorae Flavescentis and Cortex Pseudolaricis were identified by TLC.The content of oxymatrine was determined by HPLC.Symmetry C18 column(4.6 mm? 250 mm,5 ? m)with mobile phase of methanol-water-triethylamine(40:60:0.04)was used.The detective wavelength was 220 nm.Results TLC for Radix Sophorae Flavescentis and Cortex Pseudolaricis was specific .HPLC for oxymatrine had a good separation with other components,and the linear range of oxymatrine was 0.60～ 1.80 ? g and recovery rate was 99.34 %(RSD =0.71 %).Conclusion This method can be used to control the quality of Xuanshi Texiao Yaoshui.

Objective To evaluate the efficacy and clinical application value of endoscopic transpapillary cyst drainage(ETCD)on huge pancreatic pseudocysts(HPP)and pancreatic abscess.Methods According to unification standard from 2003 Jun to 2006 Jun,to select 10 disquisitive cases,in which patients with uninfected HPP were 8 cases and that with infected HPP was 1 case,and pancreatic abscess was 1 case.ETCD was adopted in all cases.The clinical treatment process and the change of relative investigation subjects were retrospectively studied.Results Endoscopic transpapillary treatment failed in 1 case,postoperative infection of HPP occurred in 2 cases and acute pancreatitis was found in 1 case.Mean follow-up was 16.5 months in 8 cases.Finally,four patients had complete resolution of HPP,3 cases had partial resolution,and the remains cavity of HPP was formed in 1 caes.Acute grave pancreatitis were cured in 2 cases and Chronic pancreatitis had resolution in 6 cases.Conclusion ETCD was safe and efficient in HPP and pancreatic abscess.Postoperative infection of HPP was the familiar complication,and obstruction of drainage path of HPP was major cause.So the crux of complications precaution and treatment was that the drainage path of HPP was unhindered.
