Purpose To explore the value of direct CT venography (CTV) for the diagnosis of varicose veins of lower limb. Materials and methods Forty patients diagnosed as varicose veins of lower limbs were enrolled. 40 patients with 56 involved limbs underwent direct CTV examination, and their images were stratified and evaluated according to the severity and the scope of the disease. Main assessment:definition and scope of CT axial scans combined with volume rendering (VR) and maximum intensity projection for the display of the varicose veins; situation for the display of perforating veins, deep veins and iliac veins;diagnostic compliance between CTV and DSA. Results All of the 56 involved limbs underwent laser intra-cavity occlusion surgery, among them 7 cases with 11 limbs underwent venous angiography under DSA at the same time. In the evaluation of the VR, excellent proportion was 92.86%(52/56), moderate proportion was 7.14%(4/56). Among the deep veins, ratio of the imaging that was able to meet the diagnostic standard was 94.34%, 88.46%and 27.27%, respectively for calf vein, femoral vein and external iliac vein. The total demonstration rate of perforating veins was 98.21%(55/56). Diagnostic compliance between CTV and DSA was 100.00%. Conclusion Lower extremity direct CTV imaging is convenient and noninvasive for patients with varicose veins, with high compliance with DSA results, thus is significantly valuable for the guide of clinical treatment.

Objective To investigate clinical efficacy of finasteride on chronic heart failure(CHF)compli-cated with benign prostatic hyperplasia(BPH)in elderly patients.Methods 100 cases of elderly patients with CHF complicated with BPH were chosen,according to the number table method,they were divided into the observation group and control group,50 cases in each group,all patients were treated according to their cardiac function to regulate anti -CHF therapy.The patients in the observation group were added with finasteride treatment,the control group pla-cebo treated patients,the measurement indexes were compared between the two groups after treatment,including pros-tate volume,N terminal pro brain natriuretic peptide concentration,creatinine,international prostate symptom score and symptom score,need operation treatment intervention,incidence acute urinary retention rate.Results After treat-ment,the prostate volume,N terminal pro brain natriuretic peptide concentration,creatinine,international prostate symptom score of symptom scores of the observation group were (23.86 ±10.27)mL,(352.63 ±72.55 )g/L, (84.0 ±11.6)mol/L,(9.3 ±4.9),those in the control group were (39.11 ±12.53)mL,(483.46 ±76.47)g/L, (99.0 ±12.8)mol/L,(13.9 ±5.6).The difference was statistically significant(t =9.47,17.56,12.33,8.48,all P <0.05);the observation group need operation treatment intervention was 16.0%,obviously less than 52.0% in the control group,there was significant difference between two groups(χ2 =21.85,P <0.05);acute urinary retention in patients with the observation group the incidence rate of 14.0%,significantly lower than 38.0% in the control group, there was significant difference between two groups(χ2 =12.83,P <0.05).Conclusion Patients with CHF compli-cated with BPH aged at the same time standard anti heart failure treatment using finasteride,significantly reduce the prostate volume,reduce the measurement indexes,and significantly reduce the rate of operation intervention patients, safe and reliable,which is worthy of clinical application.

Objective To investigate the clinical features of neonatal lower respiratory tract infection (LRTI)with respiratory syncytial virus(RSV),and to explore the relationship between clinical features and recurrcnt cough or wheezing after discharge.Methods From May 2008 to May 2013,the data of 41 neonates diagnosed as LRTI with RSV infection in New Century International Children's Hospital were analyzed retrospectively.The clinical features and follow-up results were observed.Results All the neonates had cough,92.7％ (38/41 cases) had choking,85.4％ (35/41 cases) had runny nose and nasal obstruction,31.7％ (13/41 cases) had fever,65.9％ (27/41 cases) had wheezing sound during physical examination,29.3％ (12/41 cases)of the neonates were accompanied with bacterial infection(n=29),in which 50.0％ (6/12 cases) were infected by staphylococcus aureus.Compared to the neonates only with RSV infection,the proportion of fever was higher in those with RSV combined with bacterial infection (n =12)(x2 =6.034,P ＜ 0.05),and there were no statistical differences between the neonates with or without bacterial infection in white blood cell count and with or without shadow in chest X-ray(x2 =0.859,2.064,P =0.485,0.202).Compared with the neonates without family history of atopy,the neonates with the family history of atopy were more likely to get wheezing (88.2％ vs 57.1％,x2 =4.871,P ＜ 0.05) during primary infection.During the follow-up,there was higher proportion of children with family history of atopy in the group with subsequent recurrent cough and/or wheezing than in the group without subsequent recurrent cough and/or wheezing (71.4％ vs 26.3％,x2 =6.388,P ＜ 0.05).Conclusions Cough,choking are most common symptoms in neonatal LRTI with RSV,and there is no wheezing sound during phy-sical examination in some neonates.LRTI with RSV is likely combined with bacterial infection.Wheezing is more common in the neonates with family history of atopy.The RSV LTRI neonates with family history of atopy incline to get subsequent recurrent cough or wheeze after discharge.

Objective To explore the value of the ultrasound contrast agent in conjunction with advanced contrast imaging techniques in the evaluation of the renal cortical perfusion. Methods The animal model was established with ligating renal artery to cause the renal cortical perfusion decrease of rabbits. Real-time harmonic gray scale imaging was performed to visualize the contrast enhancement of the renal cortex. After bolus injection of contrast agent SonoVue, dynamic image was observed and recorded during the first three minutes. According to the time-intensity curve (TIC), accelerating time (AT),Peak intensity (A), time to half of peak intensity (T), difference between peak and base (PBD), slope rate of the curve (β) and the product of A and β (A·β) were obtained before and after the renal artery operation. The t test and correlation analysis was used to examine the above parameters. Results Before the renal artery operation, renal cortex enhanced rapidly and obviously, the way of the enhancement was renal artery-cortex-pyramids. After ligation of renal artery, AT prolonged evidently (P<0.001), A decreased obviously (P<0.001), T obviously shortened (P<0.001), PBD decreased markedly (P<0.001), while the decline of βinduced (P<0.002) and A·βobvious dropped(P<0.001). AT, BPD and A·βcorrelated with stenosis level of renal artery. Compared with 31%－69% group, AT prolonged evidently (P<0.001). A decreased obviously (P<0.029), PBD decreased obviously (P<0.001), A·β was dropped markedly (P<0.02) in 70%-93% stenosis group. Conclusions Contrast agent combining with developed contrast specific imaging is able to detect changes of renal cortical microcirculation sensitively with the help of analysis of TIC.

Objective To observe the changes of cerebral blood flow velocities and carbon dioxide (CO_2) reactivity of cerebral vessels in children after cardiopulmonary resuscitation,and the relationship between the changes of cerebral blood flow and outcome.Methods The waveforms,cerebral blood flow velocities of left middle cerebral artery and extracranial internal carotid artery were monitored by Transcranial Doppler (TCD) in 35 post-resuscitation children. Glasgow coma score (GCS) was estimated at the same time.They were divided into three groups according to the diastolic blood flow velocities:low perfusion group,high perfusion group and near-normal perfusion group.CO_2 reactivity of cerebral vessels was induced by hyperventilation in 26 children under ventilation.Results In both low and high perfusion groups,GCS and CO_2 reactivity of cerebral vessels were significantly lower than that of near-normal perfusion group (P＜0.05);the numbers of died and withdrawing treatment patients were significantly higher than that of near-normal perfusion group (P＜0.01).Conclusion TCD monitoring is a useful technique for estimating cerebral perfusion,outcome and CO_2 reactivity of cerebral vessels of children after cardiopulmonary resuscitation.A secondary ischemic event may be caused by a forced hyperventilation therapy in the condition without TCD monitoring in post-resuscitation patients.
