ABSTRACT
In recent years, living kidney donors is getting valuable with the increasingly needs of kidney transplantation. However, living kidney donors can receive no benefits but greater incidence and severity of pain compared to other kinds of renal surgeries. Thus, it is getting popular on how to relief the postoperative pain during perioperative period for living kidney donors. As multidisciplinary cooperation developing, preoperative predictive nursing, changed analgesia mode, modified pneumoperitoneum, and postoperative application of different kinds of analgesic drugs can further relief the postoperative pain of living kindney donors. This paper sums up different modalities of pain relief in patients undergoing live donor nephrectomy to provide reference to clinical decision of living kidney transplantation.
ABSTRACT
Objective To explore the efficacy and safety of Gemcitabine and Cisplatin combination chemotherapy in treatment of muscle-invasive urothelial cell carcinoma.Methods Analyse of 72 cases of patients with muscle-invasive urothelial cell carcinoma receiving chemotherapy from September 2010 to September 2012,including 47 male and 25 female,the avarage age was 65 (86-33).All patients were received GC chemotherapy (Gemcitabine 800-1 000 mg/m2,ivgtt,dl,d8,d15; Cisplatin 70 mg/m2,ivgtt,d2).Efficacy was reviewed after 1 cycle of chemotherapy.Results Fifty-one cases in all the patients completed two or more chemotherapy cycles and CR 10 cases,PR 27 cases,total effective rate was 51.39％ (37/72).The main toxic reactions included nausea,vomit,myelosuppression,and then damage of liver and renal function.Cconclusion GC regimen is a good choice for urothelial cell carcinoma.Close follow-up and the usage of adjuvant drugs can contribute to reduce the side effect of chemotherapy.
ABSTRACT
Objective Concluding the clinical feature and prognosis of primary testicular lymphoma to improve the understanding of this disease.Methods During 1995 and 2010,17 cases of primary testicular lymphoma treated in Beijing Friendship Hospital of Capital Medical University were retrospectively analyzed of its clinical features,diagnosis,treatment and prognosis.Results Seventeen patients with a mean age of 68 years complained the testicular sohd mass as their first symptoms.The mean tumor diameter was 4.7 cm,and all patients underwent orchidectomy,and testicular non- Hodgkin's lymphoma was confirmed by pathologic examination.Fourteen cases were diffuse large B cell type and 3 cases were anaplastic large cell type.The clinical stage of all the patients was IE.Fourteen cases were followed up (3 cases were lost)with mean follow-up time of 37.8 months by outpatient interview and telephone,all patients were treated with CHOP chemotherapy,and some of them were combined with rituximab and preventive lowdose pelvic radiotherapy.Five cases died of other chronic medical complications,1 case with contralateral testicular metastasis received surgery again.There were 9 tumor free survival cases in total.Conclusion Primary testicular lymphoma is rare and more common in older men.Postoperative pathologic diagnosis is gold standard.The systemic treatment and individual therapy is the first choice for primary testicular lymphoma.
ABSTRACT
Objective To investigate the clinical characteristics and treatmentof ureteral endometriosis.MethodsA retrospective analysis was made on the clinical data of 16 cases of ureteral endometriosis of the Department of Vrology,Beijing Friendship Hapital,Affiliated to Copital Medical Universty from January.1991 to Augest.2011.ResultsSixteen cases were pathologically confirmed endometriosis,including 11 cases of outer lumen type,5 cases of lumen type ; endomctriosis lesions were all located in the lower ureter.Ureteral stricture length was 1.0-4.0 cm.During 12 months to 20 years follow-up,hydronephrosis detected by ultrasonography in 15 patients was released significantly,and no recurrence occurred except one case who was found hydronephrosis 3 years later.Ureter anastomosis was undergone later.ConclusionsUreteral endometriosis onset is undetectable which could impact renal function.Renal ultrasonography can reduce misdiagnosis.The principle of treatment is to remove the obstruction and protect renal function,and well follow-up to prevent recurrence.
ABSTRACT
Objective To investigate the feasibility and accuracy of velocity vector imaging(VVI)to assess strain and strain rate of right ventrieule(RV)during varying myocardial functional states.Methods VVI of the longitudinal RV were recorded in 7 closed-chest anesthetized mongrel dogs from the apical 4-chamber view during 3 different inotropic states.Peak dp/dt from the RV contraction during the right cardiac catheterization,which was used as the gold standard of RV contractility,was obtained simultaneously in each inotropic state.Peak systolic velocities(V), peak systolic strain rates(SR),peak systolic strains(S)at the basal, middle and apical segments of RV free wall and septal from the longitudinal axis were quantitatively measured by using VVI software system respectively.Results The peak systolic strain and strain rate of the longitudinal RV free wall and septal were increased with the infusion of dobutamine and decreased with the infusion of metoprolol.A significant correlation was found between peak RV dp/dt and RV mean strain and mean strain rate(r=0.79, 0.75;P <0.01).Among all RV segments, the peak systolic S,SR of RV basal free wall had the most significant correlation to peak dp/dt (r=0.83,0.78;P<0.01).Conclusions Strain rate imaging drived from VVI could quantitatively and sensitively detect the longitudinal RV contractile function.Peak systolic S and SR determined at the longitudinal RV basal free wall were the strong noninvasive indices of RV contractility.
ABSTRACT
Objective To investigate strain and strain rate of right ventricular(RV)based on twodimensional image by velocity vector imaging in normal subjects.Methods Thirty-two healthy adults were rolled in this study.Echocardiographic images in 4 chamber view were analyzed by conventional manual tracing for volumes and ejection fractions,which were also measured by velocity vector imaging.Myocardial velocity,strain rate,and strain were determined at the basal,mid,and apical segments of the RV free wall and ventricular septum by velocity vector imaging.Results RV ejection fractions obtained with manual tracing correlated strongly with the same indexes obtained by velocity vector imaging method in all subjects(r=0.91,P＜0.01).The strain and strain rate value of middle segment and basal segment in RV free wall were higher than those of apical segment.There were same trend in ventricular septal.The strain and strain rate of middle segment and basal segment in RV free wall were higher than those of homologous segments in ventricular septal,but the indexes of apical segment in free wail and septal had no difference.The strain and strain rate in RV were not correlated with age.Conclusions Velocity vector imaging could accurately and quantitatively assess the strain and strain rate of RV.
ABSTRACT
Objective To assess left ventricular systolic and diastolic function in patients with hypertrophic cardiomyopathy(HCM) with the aid of pulsed Doppler tissue imaging (DTI) to measure the four sides of mitral annular. Methods Thirty subjects with HCM and Twenty five age and sex matched controls were performed 2D and Doppler echocardiography . Two groups were studied with pulsed tissue Doppler imaging of the 4 sides of the mitral annulus (septal, lateral, inferior, anterior) in 4 and 2 chamber views. The velocities of systolic wave(Sa)、early diastolic filling wave (Ea)、late filling wave (Aa) and isovolumetric relaxation time were measured by DTI. Results Compared with normal control group, HCM group shows: (1) conventional data: LV wall thickness and mass indices were significantly greater. There were no significant difference in mitral flow Velocity. (2) DTI: There were more lower velocities of systolic and early diastolic filling wave. But isovolumetric relaxation time、mitra flow velocity / mitral annual early diastolic velocity ratio(E/Ea) increased. The velocities of systolic and early diastolic of septal site were the lowest among the 4 sides of the mitral annular and were the most closely with the average velocities of systolic and early diastolic of mitral annual. In addition, DTI may detect the pseudonormalization of mitral inflow. Conclusions DTI is more sensitive than conventional echocardiogram data and may be clinically used in exactly detecting left ventricular systolic and diastolic dysfunction in patients with HCM
