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 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.

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 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 compare the efficacy of different therapies for idiopathic membranous nephropathy (IMN) patients, and to discuss their rationality. Methods The clinicopathological data and therapies of 76 patients with IMN in our hospital was retrospectively analyzed and reviewed, and the efficacy was followed up.According to the different therapies, 76 patients were divided into 4 groups, including symptomatic treatment group, glucocorticoid-alone group, immunosuppressant-alone group, and glucocorticoid in combination with immunosuppressant group (combination group). Comparison and analysis of the efficacy of the different therapies were made. Results (1) The incidence of nephrotic syndrome and 24-hour proteinuria of patients in symptomatic treatment group were significantly lower than those in glucocorticoid-alone group and combination group. (2) The remission rates of 4 groups were 56.3%,73.7%,66.7% and 78.9%, respectively. In general, no statistical differences were observed in the remission rates of patients among the symptomatic treatment group, glucocorticoid-alone group and combination group. The 2-year and 5-year renal survival rates were 89.2% and 79.3%, respectively. (3) Patients in glucocorticoid-alone group and combination group were divided into low-risk, moderate-risk and high-risk patients. No difference in remission rate was observed between the two therapies for low-risk and moderate-risk patients.But for high-risk patients,the remission rate in combination group was significantly higher than that in glucocorticoid-alone group.(4) Patients in glucocorticoid-alone group and combination group were divided into remission subgroup and non-remission subgroup. It showed that only estimated glomerular filtration rate (eGFR) between these two subgroups had statistical difference, and eGFR in non-remission subgroup was lower than that in the remission subgroup. Conclusions For high-risk patients,treatment with glucocorticoid combined with immunosuppressant may improve the remission rate of proteinuria significantly.Glomerular filtration rate before treatments is an important prognostic factor.

Objective To investigate risk factors and prognosis of hemorrhagic transformation(HT)in acute cerebral infarction patients treated by intravenous thrombolysis with recombinant tissue plasminogen activator(rt-PA).Methods All 128 patients with acute cerebral infarction were treated with intravenous rtPA within 6 hours from stroke onset.The clinic records and laboratory datas of pre-and post-treatment were statistically analyzed between HT group and non-HT group to find potential risk factors to HT and contributors of prognosis.Results HT occurred in 29 patients(22.66％),including 16 patients with symptomatic ICH(12.50％)and 2 patients died(6.90％ of HT).Logistic regression analysis showed that history of atrial fibrillation(OR =1.293,95％ CI 1.224-1.589,P =0.001),CT density changes with mass effect or edema(OR =2.452,95％ CI 1.132-3.309,P =0.034),diastolic blood pressure ≥ 100 mm Hg before thrombolytic therapy(1 mm Hg =0.133 kPa,OR =9.265,95％ CI 1.435-59.836,P =0.019),blood glucose ≥ 11.1 mmol/L(OR =3.037,95％ CI 0.252-57.593,P =0.047),NIHSS score ＞ 15 points (OR =8.752,95％ CI 1.035-30.285,P =0.023)and thrombolysis time ＞ 3 h(OR =98.74,95％ CI 5.067-186.120,P =0.002)are independent risk factors for HT; among these factors,baseline blood glucose(OR =3.265,95 ％ CI 0.435-59.863,P =0.045),NIHSS score(OR =10.453,95 ％ CI 5.647-38.185,P =0.003)and thrombolysis time(OR =2.541,95％ CI 1.098-51.086,P =0.017)also are prediction factors of the prognosis of HT.Conclusion Risk factors associated with HT are diastolic blood pressure before thrombolysis,glucose level,degree of neurological deficits,CT early changes,atrial fibrillation and thrombolytic time.Glucose level,neurological deficits and thrombolysis time affects the prognosis of patients.
