Objective:To compare the diagnosis value of color echocardiography and high resolution CT for early left ventricular dysfunction.Methods:72 cases of left ventricular dysfunction patients in our hospital were chosen, and all of patients were detected with color echocardiography and high resolution CT inspection. Each patient was followed-up for 18 months and then to compare the diagnosis values of the two kind methods.Results: After 18 months follow-up review, the diagnostic accuracy of color echocardiography and high resolution CT were 95.8% (69/72) and 97.2% (70/72), respectively. Both of two methods were higher, and the difference was not statistically significant (x2=0.207,P=0.649). All sorts of cardiac function detection result, such as LVSV, LVEF, LVEDV and LVESV, were similar between color echocardiography and high-resolution CT, and the difference was not statistically significant (t=-0.775,t=1.387,t=-0.624,t=-1.209;P>0.05). Conclusion: Both of the diagnostic accuracy of color echocardiography and high-resolution CT for early left ventricular dysfunction were higher. All of them are worthy generalization and applying in clinical diagnosis for early heart failure.

Objective To detect the new views for pulmonary vascular by transesophageal echocardiography(TEE) during lung transplantation.Methods Seventeen cases with respiratory failure underwent lung transplantation.A series of scans were detected by TEE during preoperative anesthesia, preand pro-pulmonary vascular occlusion and pro-donor lung, and bronchus, pulmonary veins, pulmonary artery anastomoses.Left and right lung veins open and left and right pulmonary artery branch were key to observed.Pulmonary artery trunk and branch diameter, velocity of blood flow were measured.Results All left and right pulmonary artery,pulmonary vein images were given by TEE.TEE detected the normal blood flow velocity of pulmonary artery branches during pre-operation,average of 65 cm/s.After clipping the side of the pulmonary artery, the lateral pulmonary blood flow disappeared.TEE detected pulmonary veins,pulmonary artery anastomoses pro-operation.Except for 1 case of anastomotic pulmonary vein flow velocity increased,all the pulmonary vein and pulmonary artery branch anastomoses flow velocity increased slightly faster than those before transplantation (mean pulmonary artery branch of 160 cm/s, the average pulmonary vein 149 cm/s).Conclusions TEE can monitor diameter and flow velocity of pulmonary artery branch and pulmonary vein during lung transplantation,and can detect the rightventricular function.The views of left and right branch pulmonary artery and pulmonary vein branches play an important role during lung transplantation.

Objective To investigate the clinical value of transesophageal echocardiography during the lung transplanta tion. Methods From August 2005 to August 2009, 19 patients with advanced lung diseases received lung transplantation.The average age was(48.35±13.04) years. The echocardiographic probe was placed in patient's esophagus before surgery.The left and right pulmonary venous openings, artery blood flow velocity, right ventricular wall motion, left and right ventricular volume, right ventricular ejection fraction were recorded at different time intervals during lung transplantation, especially at the break and after completion of bronchus, pulmonary veins, and pulmonary artery anastomosis. Results The procedure included sequential-type lung transplantation in 6 cases and single lung transplantation in 13. The blood flow disappeared when blocking pulmonary artery and vein and right ventricular volume increased slightly. The right ventricular volume restored after completion of trachea, pulmonary veins, pulmonary artery anastomosis. TEE detected that the blood flow velocity of pulmonary veins, pulmonay artery anastomosis increased slightly. In 1 case the opening of the right pulmonsry artery blood flow velocity increased significantly and blood flow velocity decresed and blood oxygen partial pressure resumed after re-anastomosis of pulmonary artery. Conclusion TEE play an important role in monitoring pulmonary artery and vein anastomosis diameter and blood flow velocity and right ventricular function and predicting complications during lung transplantation.

Objective To improve the finding of prostate cancer (PCa) and prevent the unnecessary biopsies, we select proper patients for biopsy and analyze. Methods The retrospective study included 258 patients who were biopsied for suspected early PCa. Then we analyse how the age, prostate volume, PSA, transrectal ultrasound sonography (TRUS) and MRI affect the finding of prostate cancer. Results Altogether 146 BPH and 112 prostate cancer by biopsy were detected. Positive ratio of biopsy was increased with the age or PSA increases but has no relationship with the prostate volume. Combination with digital rectal examination, PSA and TRUS, the positive ratio was improved and unecessary biopsies were avoided. The detective rate reached 84.6% when all of these three parameters were positive. The sensitivity of MRI was 98.3% but specificity was only 22.4%. The total efficacy was 21.8%. Conclusions The effect of DRE, PSA and TRUS in the screening of prostate cancer should be emphasized. However, importance of MRI is limited for the early detection of PCa.

Objective To verify the safety and advantages of total transperitoneal laparoscopic nephroureterectomy (ttLNU) in the treatment of upper urinary tract urothelial carcinoma (UTUC).Methods From Jun.2013 to Jun.2014,there were 13 UTUC patients treated with ttLNU,including 7 males and 6 females.The mean age was 70.4 ± 8.3 yrs,and BMI was 23.3±4.1.Of them,11 cases were diagnosed with renal pelvis carcinoma,6 in the left and 5 in the right.2 cases were diagnosed with left ureteral carcinoma.TNM stages were T1-T3N0M0.Patients were put on lateral position and the position was not changed during the operation.A ttLNU was performed,and the specimen was removed from the middle extended inferior umbilical incision.Results The mean operative time was 188±33 (150-240) min,the intraoperative blood loss was 150.5±60.1 (50-700) ml,and the time of out-of-bed activity was between 1 and 4 d.The mean postoperative drainage time was 6.8±4.6 (3-6) d.The mean postoperative bowel function recovery time was 1.5± 1.0 (2-4) d and postoperative hospital stay was 12.8±7.0 (3-27) d.The ttLNU procedures were successfully performed in all cases without conversion to open surgery.Pathological results showed urothelial carcinoma in all cases,including 8 high grade and 5 low grade.All the surgical margins were negative.The followed up was from 2 to 12 mon,and there was no tumor recurrence and metastasis found.Conclusions Total transperitoneal laparoscopic nephroureterectomy in the treatment of upper urinary tract urothelial carcinoma is characterized by short operative time,low blood loss,decreased trauma and quick recovery.This is a safe and effective treatment option for the treatment of upper urinary tract urothelial carcinoma.

Objective To investigate the dynamic changes and coordination of macrocirculation and microcirculation in rats with severe hemorrhagic shock and septic shock. Methods A total of 20 male Sprague-Dawley rats (450～550 g) were randomly divided into two groups (n = 10) : hemorrhagic shock group (H-Shock) and septic shock group (S-Shock). 40％ of the systemic blood volume was withdrawn in 1 hour in H-Shock group.While in the S-Shock group, cereal ligation and puncture (CLP) was performed and then the abdomen was closed.Mean arterial pressure (MAP) and the end-tidal carbon dioxide (ETCO2) were recorded continuously. Cardiac ultrasonography and sublingual microcirculation were performed per hour till 12 hours or the rat die (End). A total of 12 hours were observed or the rat die. Arterial blood gas was measured at baseline (BL) , MAP ≤ 65 mmHg (Shock) and at the termination of observation respectively. Results The values reflect macrocirculation or microcirculation in the H-Shock group were all decreased than BL respectively at each time. In the S-Shock group, the values that reflect macrocirculation such as MAP, ETC02 and cardiac output (CO) showed no significant changes within 3 hours (P> 0.05) , while the values of microcirculation were decreased compared with BL respectively at each time (P < 0.05). With the progress of shock, the pH was decreased compared with BL in both groups, while the level of Lac were increased (P < 0.05). Conclusions The changes of macrocirculation and microcirculation in severe hemorrhagic shock are basically the same; while they are inconsistent in septic shock, the changes of microcirculation occurred earlier than that of macrocirculation.

To analyze respectively a case,presented with recurrent petechial and epistaxis after a 2 years history of diabetes mellitus (DM),who was hospitalized in Beijing Children's Hospital Affiliated to Capital Medical University.The clinical manifestation,examination,diagnosis and treatment were recorded.The patient was diagnosed with immune thrombocytopenia (ITP) and DM at the first admission.The initial therapy with gamma globulin didn't show ideal effect.The pediatric specialists from the department of ENT,Hematology/Oncology,Endocrinology,Pharmacy and Immunodeficiency Clinic were invited to discuss the case.The final diagnosis of autoimmune polyglandular syndrome (APS) was made and supplementary steroid treatment was started.But the response of the steroid therapy was poor.Once again with the multidisciplinary consultation,the patient received several schemes of Rituximab under the informed consent.This treatment reached a stable condition for almost 7 years.APS should be considered when DM patient showed the manifestation of other immune organ damages.Rituximab immunosuppressive therapy should be tried when the response to first-line treatment was poor.

Objective To investigate the application value of transesophageal echocardiography(TEE) in allogeneic lung transplantation. Methods The study enrolled 37 patients receiving allogeneic lung transplantation because of end stage lung disease,including sequential bilateral lung transplantation 20 cases and unilateral lung transplantation 17 cases,the latter included 4 cases with extracorporeal membrane oxygenation (ECM O).Echocardiographic parameters before surgery,including right ventricular transverse diameter (RVTD),left ventricular transverse diameter (LVTD),right atrial transverse diameter (RATD), left atrial transverse diameter (LATD),main pulmonary artery (DMPA),left ventricular ejection fraction (LVEF),pulmonary arterial systolic pressure (SPAP),and TEE parameters during surgery,including pulmonary artery anastomosis diameters (DRPAand/or DLPA) and blood flow velocity (VRPAand/or VLPA), pulmonary vein anastomosis blood flow velocity (V RPVand/or VLPV),were measured. Results ①Preoperative transthoracic echocardiographic showed a slight increase of right heart in patients with allogeneic lung transplantation,different degrees of increase in SPAP,a normal or slightly increase of D MPA and a normal LVEF,according to the ASE guidelines. ②Compared with pre-operation,the diameters of left and right pulmonary artery decreased ( P < 0.001) and the blood flow velocity of arteries and veins increased ( P <0.001). ③Patients with ECMO support had a higher SPAP before operation ( P <0.05) and a lower LVEF ( P <0.05),but within a normal range.The blood flow velocity of pulmonary artery and vein had no difference between two groups ( P > 0.05). Conclusions During allogeneic lung transplantation,TEE plays an important role in the monitor of pulmonary arteriovenous anastomosis. It could remind the surgeon whether anastomosis is narrow timely,and determine the patient′s hemodynamic status and cardiac load to guide the surgical process.

Objective To investigate the effects of radical prostatectomy on the overall survival (OS)and tumor-specific survival in prostate cancer(PCa)patients aged 75 years and older.Methods Clinical data of patients aged 75 and older with localized PCa from Surveillance,Epidemiology,and End Results(SEER)Database from 2004 to 2016 were retrospectively analyzed.There were 17 899 cases of PCa undergoing radical prostatectomy and 3 648 cases of PCa without surgery in this study.The OS and prostate cancer-specific survival(PSS)were compared between the surgery group and the nonsurgery group.Results For 75-79-year-old patients with high-risk localized PCa,the OS and PSS in the surgery group were better than in the non-surgery group (OR =1.49,95 ％ CI:1.22 ～ 1.82,P ＜ 0.01;OR=1.43,95％CI:1.09～2.04,P＜0.05).For patients aged 75-79 years with low-risk PCa and patients aged 80 years and older with low-,middle-,or high-risk PCa,the OS was worse in the surgery group than in the non-surgery group(OR =0.54,95％CI:0.38～0.76,P＜0.01;OR =0.47,95％CI:0.34～0.66,P＜0.01;OR =0.58,95％CI:0.44～0.78,P＜0.01;OR =0.59,95％CI:0.51 ～0.68,P＜0.01).For patients aged 75-79 years with low-or medium-risk PCa and patients aged 80 years and older with medium-risk PCa,there was no statistical difference in PSS between the surgery and non-surgery groups(P＞0.05).Conclusions Age limits for prostatectomy should be extended as a result of increasing average life expectancy.Patients aged 75-79 years with high-risk PCa can be considered for surgical treatment,while it should not be recommended for patients aged 75-79 years with low-or medium-risk localized PCa or aged more than 80 years.Many factors should be considered in making treatment decisions for prostate cancer.
