Objective To analyze the alterations of serum protein fingerprint in patients with hypertensive disorder complicating pregnancy(HDCP),screen serum biomarker and establish a diagnostic model of HDCP.Methods Surface-enhanced laser desorption lionization-time of flight-mass spectrometry (SELDI-TOF-MS)technology was used to analyze serum including 25 cases of HDCP patients and 30 cases of age-,gravity-and parity-matched healthy term pregnant women on IMAC3-Cu proteinchip before delivery. Biomarker Wizard and Biomarker Pattern software was used to detect protein peaks significantly different between HDCP and controls,and establish a primary diagnostic model of HDCP.This model was further evaluated by blind test using other 16 parts of serum protein fingerprint.Results Ten protein peaks were significantly different at the molecular range of 2000-50 000(P

Objective To assess the feasibility of three-dimensional contrast-enhanced ultrasonic cholangiography(3D-CEUSC) in cadaver liver.Methods The 3D-CEUSC was performed in 6 cases of cadaver liver.Image quality of 3D-CEUSC was evaluated.The visualization of branching orders,the degree of visibility and coincidence of morphous were compared with those of cholangiagraphy using fluoroscopy.Results The imaging quality of 3D-CEUSC was inferior to that of cholangiography with significant difference.The three-dimensional biliary tree structures were visualized in all 6 3D-CEUSC.The maximum visualization of branching orders in 3D-CEUSC was (3.67±0.52),which was equal to the results(4.00±0.63)by cholangiography (P=0.465).The degrees of visibility of biliary tree were equivalent with those by cholangiography in the first and second order with significant difference.The coincidence of morphous was excellent compared the images of 3D-CEUSC with direct X-ray cholangiography.Conclusion 3D-CEUSC is a new technique as a useful supplement to cholangiography in evaluation of biliary anatomy and variation before graft harvesting in LDLT.

Objective To investigate children′s myelodysplastic hematopoietic cells reaction to interleukin (IL)-15.Methods CD 34 + cells in bone marrow from 18 myelodysplast syndrome(MDS) patients were purified by an immunomagnetic beads sorting system. Apoptosis of hematopoietic precursors was assayed by propidium iodine staining and flow cytometric analysis.Results On 8th cultured day,when IL-15 concentration was between 0-100 ng/ml,it could suppress apoptosis of hematopoietic cells in MDS patients in a dose-and- time dependent manner. IL-15 in study group significanthy lower than that of control group.Conclusion IL-15 may partly suppress apoptosis of hematopoietic cells in MDS patients.

OBJECTIVETo study the protective effect of carbon monoxide (CO) inhalation on the serious limb ischemia/reperfusion (I/R) injury, and which effects caused to shock in rats.

METHODS36 SD rats were randomly divided into I/R, I/R + CO (RC), sham operation (S) groups. I/R injury models were made by the occlusion of the femoral artery for 8 h and the reperfusion for 12 h, 10 d. Before reperfusion of 2 h, RC group started to breathe medical air containing CO (the volume fraction of CO: 0.075%) continuously, until after reperfusion for 4 h, a total of inhalation 6 h. S, I/R groups exposed to air, breathe freely. Caudal artery pressures (CAP), ten days survival rate, serum lactate dehydrogenase (LDH) and creatine kinase (CK) activity, limb wet - to - dry weight ratio (W/D) and the pathologic changes of limb were observed.

RESULTSOnce the reperfusion started, the CAP decreased rapidly in I/R group, and the mean reduced to(5.3259 +/- 0.3832) kPa when reperfusion for 8 h. Compared to I/R group, the CAP decreased slower and smaller in RC group, moreover, its mean reduced to (8.3300 +/- 0.4224) kPa when reperfusion for 8 h. The 10 d survival rate in I/R group was that 8 rats died all between reperfusion for 13 - 20 h. Only 1 rat died in RC group and the other 7 rats were still alive when reperfusion for 10 d. Compared to I/R group, the pathological features of the ischemic limb were significant ly improved, and the figures of W/D, serum LDH and CK value were remarkable lower in RC group (P < 0.05).

CONCLUSIONInhaling exogenous low-dose CO has a reverse regulation in the blood pressure decline caused by serious limb I/R injury in rats. And at the same time, it can effectively prevent the occurrence of shock, reduce physical damage, significantly increase the survival rate of animals.

OBJECTIVETo study the protective effect of carbon monoxide(CO) inhalation in the limb ischemia/reperfusion (I/R) injury of rats.

METHODSForty-four Sprague-Dawley rats were randomly divided into three groups: S, I/R and RC groups. I/R injury model was made by the occlusion of the femoral artery for four hours and the reperfusion for forty-eight hours. RC group was exposed to medical air mixed CO (the volume fraction of CO: 0.05%) during limb reperfusion in rats. The other two groups were exposed to the routine air. Gross morphology of the ischemic limb, wet-to-dry weight ratio (W/D), and skeletal muscle histopathology were observed. The apoptosis index and expression levels of Bax and Bcl-2 in the muscle were assessed with Flow Cytometry. The activities of serum lactate dehydrogenase (LDH) and creatine kinase (CK) were tested by Automatic Biochemical Analyzer.

RESULTSCompared to I/R group, W/D, serum LDH and CK activities, the apoptosis index and Bax expression level in the muscle were all significantly decreased, the Bcl-2 expression level was significantly increased, gross morphology of the ischemic limb and muscle histopathology were obviously improved in RC group.

CONCLUSIONInhaling exogenous CO can attenuate limb I/R injury.
