Objective To study the changes of platelet function in patients with hypertensive disorder complicating pregnancy (HDCP). Methods Forty non-pregnant women, 40 normal late pregnant women and 50 women with HDCP were in cluded in this study. Platelet count were determined by cell-DYN, the platelet alphagranule membrane protein (GMP-140) by radio-immunoassay and thrombosis bla smixgenz (TXB_2) and ?tissue platelet protein (?-tg) by ELISA. Platelet aggregation rate (Pagt) and pletelet adhesion rate (PADT) were also measured. Results The platelet count in non-pregnant, late pregnant and HDCP group were (206?48)?109/L, (204?52)?109/L and (172?51)?109/L, respectively, and that in the HDCP group was significantly lower than the other two. The levels of GMP-140, TXB_2, ?-TG, PAdT and PAgT were (7.9?2.8) ?g/L, (73.6?40.8) ng/L, (16.3?9.5) ?g/L, (18?9)% and (28?10)% in the non-pregnant group, (12.2?3.8) ?g/L, (80.0?39.6) ?g/L, (18.5?9.8) ?g/L, (20?8)% and (29?10)% in the late pregnant group and (25.1?3.8) ?g/L, (107.6?32.8) ng/L, (23.9?9.2) ?g/L, (30?10)% and (40?12)% in the HDCP group. All the above values in the HDCP group were significantly higher than those in the other two groups (P

OBJECTIVE:To observe the clinical efficacy of recombinant human brain natriuretic peptide (rhBNP) combined with levosimendan in acute decompensated heart failure(ADHF). METHODS:In retrospective study,120 cases diagnosed as AD-HF were divided into observation group and control group according to treatment plan,with 60 cases in each group. The patients of control group received rhBNP on the basis of conventional treatment,intravenously pulsed with dose of 0.15 μg/kg firstly,then maintained dose of 0.007 5 μg/kg viacontinuous intravenous pumping for 24-72 h;On the basis of control group,treatment group received levosimendan with loading-dose of 12 μg/(kg·min)for 10 min,maintenance dose of 0.1 μg/(kg·min)via intravenous pump,for 24 h,adjusted according to clinical manifestations of patients. The vital signs,hemodynamic and UCG indexes,the rate of dyspnea recovery,plasma level of BNP,urine and the occurrence of ADR were recorded in 2 groups. RESULTS:The vital sign and hemodynamic indexes of control group had no significant change 1 h after treatment;the levels of HR,RR,SBP,MPAP and MPCWP in 2 groups after treatment were significantly lower than before,while the levels of SaO2 and CO were significantly higher than before,with statistical significance (P<0.05). The levels of HR,RR,SBP,MPAP and MPCWP in observation group 1,2, 4 h after treatment were significantly lower than in control group,while the levels of SaO2 and CO were significantly higher than control group,with statistical significance (P<0.05);there was no statistical significance in vital sign and hemodynamic indexes between 2 groups at other time points (P>0.05). 48 h after treatment,LVEF of 2 groups were increased while plasma levels of BNP were decreased,compared to before treatment;the improvement of observation group was more significant than control group,with statistical significance(P<0.05). And the urine volume of observation group were significantly higher than that of con-trol group 24,48 h after treatment,with statistical significance(P<0.05). There was no statistical significance in the rate of dys-pnea recovery at different time points and the incidence of ADR after treatment between 2 groups (P>0.05). CONCLU-SIONS:rhBNP combined with levosimendan could effectively improve vital sign,hemodynamic indexes,UCG indexes and dys-pnea,and decrease the plasma level of BNP with good safety.

Objective To investigate the imaging findings of primary hepatic carcinoid tumor with dynamic MRI and spiral CT.Methods Eleven cases with pathologically confirmed primary hepatic carcinoid tumor were analyzed retrospectively.Four cases were examined with spiral CT,and 8 cases were examined with MRL Results Two of 11 cases had multiple tumors,presenting as two or more nodular lesions,while the remaining 9 cases had single tumor.Four cases showed well-defined low density on the plain scan of CT,with central irregular cystic areas.Lesions enhanced unevenly on arterial phase of CT,with no enhancement in the central part The edge of lesions showed delayed reduced enhancement on portal vein phase.than the arterial phase,while non-enhanced lesions in the center areas.Eight cases were detected by MRI,seven On MRI,7 of 8 lesions showed uneven low signal on T_1WI and high signal with central low intensity on T_2WI.On arterial phase of MRI,7 cases had uneven enhancement at the peripheral part and irregular non-enhanced signal in center.Lesions showed delayed mild enhancement in the peripheral parts,with a relatively smaller non-enhanced central area.One case was cystic,with high signal included in the extensive low density on T_1WI.The case appeared high signal on T_2WI and had uneven enhancement at the edge on arterial phase,low signal on delayed phase.Conclusion Primary hepatic carcinoid tumor exhibits some imaging features on plain and dynamic contrast-enhanced MRI and spiral CT,which can be the clue for the diagnosis.

Objective To summarize the clinical symptoms of patients with non-erosive reflux disease(NERD) and reflux esophagitis(RE),which is helpful to the differential diagnosis.Methods Outpatients who met the criteria of NERD or RE according to the Montreal definition in Gastroenterology Department Wuhan Union Hospital from 2010-2014 were enrolled in our study.Clinical data were comprehensively collected.Incidence of disease,severity,frequency of esophageal and extraesophageal symptoms,and the rates of overlapping with functional dyspepsia (FD) or irritable bowel syndrome (IBS) were all studied.Results Totally 446 subjects were recruited,including 225 patients with NERD and 221patients with RE.The occurrence rates of esophageal symptoms including heartburn [76.0％ (171/225) vs 52.0％ (115/221),P ＜ 0.01] and acid regurgitation [74.7％ (168/225) vs 54.3％ (120/221),P ＜0.05] in NERD group were significantly higher than those in RE patients,with more severe and frequent (P ＜ 0.05).Despite the rates of food regurgitation were similar,NERD patients behaved more severely and frequently (P ＜ 0.05).Extraesophageal symptoms including throat burning and foreign body sensation in NERD group [40.9％ (92/225) vs 27.6％ (61/221),42.2％ (95/225) vs 31.7％ (70/221),all P ＜0.05] were also higher than those in RE group,the degree of which was more severe too (P ＜ 0.05).RE patients claimed a higher proportion of chronic cough.The incidences of overlapping with IBS in two groups were similar.But there were more patients with FD in NERD group [72.0％ (162/225) vs 62.9％ (139/221),P ＜ 0.05] than in RE group.Conclusions The menifestations and degree of esophageal and extraesophageal symptoms in patients with NERD or RE are different,as well as comorbidities such as FD and IBS.These results suggest that NERD and RE are independent diseases.

Objective　To evaluate the effectiveness of intratracheal tube suctioning by respiratory mechanics measurement.Methods　The indexes of respiratory mechanics,including respiratory rate,expiratory tidal volume,% leak around the tube,dynamic respiratory compliance and mean airway resistance were measured just before and 20 minutes after intraendotracheal tube suction in mechanical ventilated children with respiratory failure.Results　Fifty-two measurements was carried out in 11 patie nts.The mean values of respiratory risistance was (116.73±27.12)cmH2O/L.s before suctioning and (93.38±26.64)cmH2O/L.s after suctioning,with significant differrence(P＜0.01)；The mean values of % leak around the tacheal tube dereased from(18.12±4.12)% before suctioning to (8.71±3.76)% after suctioning (P＜0.05),The mean values of expiratory tidal valume was markedly increased from(7.31±2.12)ml/kg before suctioning to(5.72±1.2)ml/kg after suctioning(P＜0.01),The total respiraory rate markedly decreased after suctioning.Conclusion　The respiratory mechanics measurement is very useful to evaluate the airway patient.The removal of secretions is crucial in respiratory managemet.

ObjectiveTo design multi-adaptive filter based on radial basis function (MAF-RBF) for efficiently extracting somatosensory evoked potential (SEP) in real-time SEP monitoring.MethodsWith the optimization of important parameters that influence the performance of radial basis function neural network,the performance of extracting SEP was compared to that of a multi-adaptive filter (MAF),which developed from the combination of well-developed adaptive noise canceller and adaptive signal enhancer.ResultsIn this simulation study,the outputs of MAF-RBF showed a similar waveform with SEP template signals,and a smoother waveform than the.output of MAF.ConclusionWith appropriate parameter values,MAF-RBFNN is able to extract the latency and amplitude of SEP from the extremely noisy background rapidly and reliably without averaging.
