Based on the study of four diagnostic methods in Treatise on Exogenous Febrile Diseases,this dissertation analysed the cause of differentiation of syndrome unavailable,and indicated that:differentiation of syndrome unavailable resulted from multi-reasons.The patients who had symptoms and signs but all the modern physics and chemistry index were normal,the data get from traditional four diagnostic methods were useful to discriminate and estimate diseases.Modern physics and chemistry index can help in improving exactitude,but we cannot ignore traditional diagnostic methods.

Objective To investigate the relationship of the polymorphisms of hURAT1gene in exon 1 C258T and the compnents of metabolism syndrome.Methods This research is divided into the hyperuricemia groop(138 examples)and the healthy matched controls(117 examples),which selected of the two groops were determined body high,body medical history;They were checked blood uric acid,fasting blood glucose,blood-fat,hepatic enzyme,urea nitrogen and blood creatinine.Analysis the polymorphisms of hURAT1 gene in exon 1 C258T by polymerase chain reaction technique.Investigate the dependablity beween the blood uric acid,fasting blood glucose,systolic blood pressure,diastolic blood pressure,total chloesterol,triacylglycerol,body mass index,waistline,rump circumference and the different genetypes.Results The differences have statiscal significance in UA,SBP,DBP,TC,TG,BMI,WHR beween the CC genetype and the CT genetype(P

Objective To investigate the risk factors,management and prophylaxis of dangerous placenta previa.Methods The clinical data of 407 cases of placenta previa were reviewed,36 cases of them with dangerous placenta previa.Comparison was made between group A (dangerous placenta previa,36 cases) and group B (non dangerous placenta previa,371 cases) in terms of age,number of pregnancy and number of ceasarean delivery.Results The incidence rates of pregnant women in group A age ≥ 35years,number of pregnancy ≥3times,and cesarean delivery≥2times were 55.6％,61.1％,25.0％,which were significantly higher than those of group B (25.6％,27.7％,2.4％),the differences were statistically significant (x2 =7.71,8.99,21.97,all P ＜ 0.01).Among the 36 cases of dangerous placenta previa,12 cases were diagnosed with concomitant placenta increta.The specificity and sensitivity for detection of placenta increta were 90.5％ (19/21) and 83.9％ (10/12) of ultrasonography respectively,and those were 100.0％ (3/3) and 87.5％ (7/8) of MRI.Of the 36 dangerous placenta previa patients,two patients were treated with induced labour due to unexpected pregnancy under 28 weeks,while the others were refer to surgical operation.5 surgical patients experienced uncontrollable postpartum haemorrhage which necessitated histectomy,while the other 31 cases received conservative operation.Rate of histectomy was 13.9(5/36).Conclusion Dangerous placenta previa is associated with advanced age,multiple pregnancy and multiple cesarean delivery.Accurate preoperational evaluation of the placenta previa should be acquired with ultrasonography and MRI to detect placenta increta,provide information for treatment selection,and prevent postpartum haemorrhage.

Objective To investigate the applicable value of tissue synchronization imaging (TSI)by real-time thriplane echocardiography (RT3PE)in cardiac resynchronization therapy (CRT).Methods Twenty-four patients with heart failure scheduled for CRT and 24 healthy controls were enrolled.Two dimensional echocardiography was performed to get the left ventricular internal diameter at end-diastole and end-systole(LVIDd,LVIDs ),left ventricular ejection fraction (LVEF ),velocity time integral of left ventricular outflow tract flow (VTILVOT ).The RT3PE TSI was performed to measure the time to peak systolic velocities(Tp)of left ventricle basal and middle segments(12 segments),software will automatically calculate the maximal difierence (12-Tp-DIF)and standard deviation (12-Tp-SD)of Tp in 12 segment. Identity the segment where wall motion most delay and to guide electrode placement.AV and VV interval optimization were performed under guidance of TSI after 1 month of CRT.Results In before CRT,after CRT,after optimization and control group,LVIDd,Tp,LVIDs,12-Tp-DIF and 12-Tp-SD were decreased in the order,LVEF and VTILVOT were increased in the order.There were significant difference between the groups(all P < 0.05 ).TSI showed that left ventricular systolic dyssynchrony was present in all patients before CRT.The most delay segment and electrode location was consistent.There were close correlation between 12-Tp-DIF and LVEF (r =-0.70,P =0.000),between 12-Tp-SD and LVEF(r =-0.73,P =0.000).Conclusions Left ventricular systolic synchronicity can be evaluated accurately and intuitively using TSI by RT3PE.It has important clinical significance in prospectively select patients for CRT,help to guide electrode placement and to optimize device programming.

Objective:To analyze the curative effect of tripterygium on NOD mice and the possible mechanisms.Methods:NOD mice were divided into 2 groups,Group A:tripterygium treatment(0.07 mg/kg,intraperitoneal injection,12 weeks);Group B:saline control.BALB/c mice were enrolled as control group( Group C).Results:After experiment,Group A had lower salivary flow rate than these of Group C,but higher than these of Group B at 12 and 20 weeks old( P<0.05).Group A had higher rate of inflammatory cells apoptosis than these of Group B and Group C(P<0.05).Group A mice had lower levels of TNF-α,IL-6 and IL-1βthan these of Group B(P<0.05),but higher than these of Group C(P<0.05).Group A mice had a higher level of SHIP-1 but a lower level of Mir-155 than these of Group B mice(P<0.05).Group A mice had a better neuroelectrophysiological outcomes than these of Group B mice ( P<0.05).Conclusion:Tripterygium can meliorate the sailoadentitis of NOD mice,which may though activating the SHIP-1/Mir-155 signaling pathway.

Objective To investigate the effect of VEGF on proliferation and migration of oligodendrocyte precursor cells. Methods To isolate and culture of oligodendrocyte precursor cells from mice. VEGF acts on the oligodendrocyte precursor cells for 48 h, meanwhile, the control group was set up and treated without VEGF. The proliferation of cells was detected by MTT assay, the cell migration was detected with a Boyden chamber, the levels of MMP-9, MMP-2, β-catenin, C-myc, cyclin D1 proteins in the cells were detected by western blotting. Wnt/β-catenin signaling pathway activator LiCl treated the oligodendrocyte precursor cells for 48 h, and the cell proliferation and migration were detected. Results The survival rate and number of migrated oligodendrocyte precursor cells were significantly higher than those of the control group after treated with VEGF (P＜ 0. 01). The levels of MMP-9, MMP-2, β-catenin, C-myc and cyclin D1 in the oligodendrocyte precursor cells after treated with VEGF were significantly higher than those in the control group (P＜ 0. 01). The cell proliferation and migration after treated with Wnt/β-catenin signaling activator LiCl were consistent with the proliferation and migration of cells after treated with VEGF. Conclusions VEGF promotes proliferation and migration of oligodendrocyte precursor cells. The mechanism of action is related to Wnt/β-catenin signaling pathway.
