Objective To evaluate the increased carotid artery pulsatility index(PI) and resistance index (RI) in young obese males by Doppler ultrasound.Methods All of the volunteers without local and systemic disease included 48 young obese males (observation group) and 100 healthy males with the same age(control group).Common carotid artery had to come into practice in all of the volunteer by pulsed Doppler ultrasound to calculate the PI and R[.Results The average of RI,PI,body mass index (BMI),systolic pressure,diastolic pressure,fasting plasma insulin,fasting C-peptide,triglyceride,low density lipoprotein cholesterol and high sensitivity C reactive protein in observation group were significantly higher than those in control group [0.70 ± 0.10 vs.0.60 + 0.10,1.48±0.30 vs.1.00 ± 0.10,(36.6 ± 3.4) kg/m2 vs.(23.6 ± 1.6) kg/m2,(127.5 ± 14.3) mm Hg(1 mm Hg =0.133 kPa) vs.(110.5 ± 11.0) mm Hg,(78.8 ±9.8) mm Hgvs.(69.9 ±7.6) mm Hg,(27.5 ± 19.6) mU/L vs.(8.8 +8.8) mU/L,(3.7 ± 1.6) pmol/L vs.(1.8 ± 1.2)pmol/L,(3.9 ± 2.0) mmol/L vs.(2.1 ± 1.3) mmol/L,(3.1 ± 0.7) mmol/L vs.(2.3 ± 0.7) mmol/L,(4.0 ± 4.4)mg/L vs.(1.3 ± 1.2) mg/L,P ＜ 0.05].Conclusions The characteristic of vascular properties in young obese males with normal blood pressure and without other cardiac risk factor is the decrease of blood wall compliance and the increase of resistance.The change of artery in the incipient properties in young obese males is the vascular function.Further studies will be required to prove thai whether early intervention will improve vascular function such as diet and practice.

Objective To study the estimated value on normal reference ranges of inferior vena cava (IVC) Doppler indices from gestation 16 to 40 weeks of fetus with color ultrasound.Methods Seven hundred and forty-four single birth gravida with gestation 16 to 40 weeks were grouped according to the gestational weeks with 27-35 cases each.The IVC Doppler indices were measured by color ultrasound,including preload index,peak velocity index and pulsatile index.Results All IVC Doppler indices rapidly declined from gestation 16 to 24 weeks,and they were relatively constant or slightly decreased throughout the end of pregnancy.Conclusions To set up the normal reference ranges of IVC Doppler indices for gestation from 16 to 40 weeks means a lot for every pregnant.This normative data may be a useful noninvasive tool for evaluation of fetal cardiac function.

Objective To discuss the application effects of fast track surgery treatment in hysterectomy. Methods 120 patients underwent hysterectomy. They were randomly assigned to two groups,namely,fast track sur-gery group(60 cases) and control group(60 cases ). two groups underwent separately fast track surgery mode and tradi-tional mode therapy. To observe the duration of passing flatus, the hospital stay, the aching time, the complication rate after operation between two groups. Results All patients got recovery. The duration of passing flatus(29.2±7.9) h,the aching time 96.7% (58/60)、the hospital stay( 3.9±2.5 )d of fast track surgery group were significantly shorter than the duration of passing flatus (50.3±15.8 ) h 、the aching time 8.3% (5/60)、the hospital stay (6.7±2.8 ) d of control group( allP<0.01 ). there was no severe complication in two groups. Conclusion Fast track surgery treat-ment mode could accelerate postoperative rehabilitation of hysterectomy patients. It shoud be popularized.

requirement of medical materials for hemolysis experiment (<5%) .MTT assay showed that , after 4 days of culture , the optical densi-ties were 0.498 ±0.218 and 0.566 ±0.266 in the 120℃12 h and 24 h groups and 0.668 ±0.268 and 0.769 ±0.213 in the 150℃12 h and 24 h groups, while after 8 days, the optical densities were 0.767 ±0.267 and 0.836 ±0.236 in the 120℃12 h and 24 h groups and 0.765 ±0.265 and 0.903 ±0.303 in the 150℃12 h and 24 h groups, all significantly higher than in the non-CaTiO3 group at 4 (0.341 ±0.143) and 8 days (0.731 ±0.121) (P<0.05). Conclusion The CaTiO3 coating on titanium is neither mutagenic nor hemolytic and has no toxicity on osteoblasts .Instead, it can promote the proliferation of osteoblasts , and therefore is a valuable coating material for implants .

Objective To investigate the effect of preconditioning with sodium butyrate on myocardial I/R injury. Methods Anesthetized rats were treated with sodium butyrate (100 or 300 mg/kg, i.p.) 30 mins before ischemia, and then subjected to ischemia for 30 min followed by reperfusion for 4 h. LDH, CK, TNF-α, IL-6, HMGB1, infarct size, MDA and SOD activity were measured. The infracted size was tested by TTC assay; The expression of HMGB1 was observed by western blot. Results After 4 h reperfusion, pretreatment of sodium butyrate (300 mg/kg) could significantly reduce the infarct size and the levels of LDH and CK (P<0.05)comparing to the control group; inhibit the increase of the MDA level and the decrease of the SOD level(P<0.05), also inhibit the expression of TNF-α, IL-6 and HMGB1 (all P < 0.05) induced by I/R. Conclusion Preconditioning of sodium butyrate can attenuate myocardial I/R injury by inhibiting inflammation response.

Objective To study the incidence of ventilator-associated pneumonia(VAP)and antimicrobial resistance of pathogens in an intensive care unit(ICU).Methods The occurrence of VAP in hospitalized patients with mechan-ical ventilation>48 hours between January 2011 and December 2012 were investigated,species and antimicrobial re-sistance of pathogens causing early onset-VAP (E-VAP,mechanical ventilation≤4 d)and late-onset VAP(L-VAP, mechanical ventilation>4 d)were compared.Results A total of 1 76 patients were investigated,incidence of VAP was 44.32% (78 cases);With the prolongation of mechical ventilation,incidence of VAP increased gradually (χ2=52.561,P<0.001).The incidence of L-VAP was significantly higher than E-VAP (58.33% [70/120]vs 14.29%[8/56])(χ2= 30.02,P<0.001).A total of 178 pathogens were isolated,gram-negative bacteria,gram-positive bac-teria and fungi were 104(58.43% ),46(25.84% ),and 28(15.73% )isolates respectively;97(54.49% )multidrug-resistance/pandrug resistance organisms (MDRO)were isolated. MDRO isolation rate in L-VAP patients was high-er than E-VAP patients([58.86% ,n= 93]vs [20.00% ,n= 4]),resistance rate of major pathogens causing L-VAP was significantly higher than E-VAP patients(allP<0.05).Fungi infection only occurred in L-VAP patients,the total antimicrobial resistance rate was 12.14% .Conclusion The prolongation of mechanical ventilation can increase the incidence of VAP,and resistance rate of pathogen in L-VAP is high.

Objective To investigate the changes of multifocal electroretinogram ( mf-ERG ) in patients with Parkinson′s disease.Methods Forty-five Parkinson′s disease patients ( 70 eyes ) and 35 normal controls (60 eyes) enrolled in the Second Affiliated Hospital of Soochow University from February 2015 to February 2016 received mf-ERG examination and general ophthalmology examinations including best corrected vision acuity, slit-lamp test, fundus examination, intraocular pressure and vision field test. Results The amplitude density of P 1 wave in Parkinson′s disease patients was dramatically decreased in ring 1, ring 2 and ring 5 compared with the normal controls (amplitude density of P1 in ring 1:(100.58 ± 41.19) nV/deg2 vs (138.10 ±17.16) nV/deg2,t=5.086,P<0.01; amplitude density of P1 in ring 2:(21.93 ±7.46) nV/deg2 vs (37.56 ±9.39) nV/deg2, t=9.844, P<0.01; amplitude density of P1 in ring 5:(7.07 ±3.04) nV/deg2 vs (10.22 ±3.68) nV/deg2 ,t=4.924, P<0.01).The latency of P1 wave in ring 1, ring 3 in Parkinson′s disease patients was significantly higher than the control group (latency of P1 wave in ring 1:(42.72 ±8.09) ms vs (37.90 ±5.95) ms, t=-3.155, P<0.01;latency of P1 wave in ring 3:(41.20 ±7.63) ms vs (37.80 ±4.59) ms, t=-2.995, P<0.01).The implicit time of N1 wave in ring 1 in Parkinson′s disease patients was delayed , which had statistically significant difference compared with the normal controls ((21.92 ±7.87) ms vs (19.04 ±4.19) ms, t=-2.012, P=0.046).However, in the amplitude of N1 wave, there was no statistically significant difference between the two groups . Conclusions The vision function has already decreased in Parkinson′s disease patients , even before the vision acuity is normal .The mf-ERG test can find the changes of vision function in Parkinson′s disease patients, which are the decrease of amplitude density of P 1 , the latency of implicit times of P 1 wave and N1 wave in some regions of the retina .
