They were followed up for 2 years. Results Detrusor areflexia was found in 76.33% (129/169) patients, among them there were 27.22% (46/169) patients appeared hyper-compliance, and 7.10% (12/169) patients appeared reflux. The video-urodynamic characteristics showed over activity and low-compliance in 12.43% (21/169) patients, including reflux in 5 cases. Different management was chosen according to the video-urodynamic examination. No special complication was observed after 2 years follow-up. Conclusion The majority patients with infra-sacral cord injury appeared detrusor areflexia and hyper-compliance. Special management according to the video-urodynamic characteristics is important for protecting upper urinary tract and preventing urinary system infection.

Objective To analyse the clinical efficacy of methotrexate (MTX) combined with intrauterine embryo sac garrotte injection in the treatment of cesarean scar pregnancy (CSP), and discuss its clinical significance. Methods A total of 77 patients with CSP treated in our hospital during June 2013 to December 2016 were selected in this study. Forty patients treated with embryo sac destruction and methotrexate injection were included in the observation group, while 37 cases treated by uterine artery embolization combined with curettage were used as the control group. The time of vaginal bleeding, the time of postoperative blood level of human chorionic gonadotropin (HCG) returned to the normal level, average hospitalization cost and the curative rate were recorded in two groups. All patients were followed up by the outpatient visit. Results In the observation group, the vaginal bleeding time [(22.1±6.7) days vs. (29.5±10.8) days] and treatment cost [(8774.2 ± 714.5) yuan vs. (15258.3 ± 1084.2) yuan] were less than those of the control group (P<0.001). There were no significant differences in the recovery time of HCG [(26.4±9.0) days vs. (25.1±10.4) days] and treatment success rate (87.5%vs. 91.9%) between the two groups (P>0.05). No bleeding or threatened rupture of scar were found in two groups of patients. Conclusion In this study, we take the embryo sac puncture combined with methotrexate injection in the treatment of scar pregnancy. This method has the advantages of low operative difficulty, definite clinical curative effect and low cost

Objective To prepare and explore the pharmacokinetic parameters for ~ 99 Tc~ m -ASON-EGF in healthy rabbits. Methods ~ 99 Tc~ m -ASON-EGF was prepared according to previous methods and its changes of concentration in blood were measured by radioactivity counts per minute. The experimental data were dealt with by 3p97 software and its true compartment model was estimated by AIC value, R~ 2 value, the 1/c and F test. Subsequently, its half-life of distribution (T_ 1/2 ?), half-life of elimination (T_ 1/2 ?), central compartment volume of distribution (Vc), total apparent volume of distribution (Vd) and total rate of clearance (CL) were calculated by the software. Finally, the binding rate of plasma protein was determined by trichloroacetic acid precipitation. Results The best model of ~ 99 Tc~ m -ASON-EGF in vivo was two-compartment model and its T_ 1/2 ?, T_ 1/2 ?, Vc, Vd and CL were 5.28 min, 89.23 min, 67.8 ml, 915.6 ml and 7.1 ml/min respectively. After being incubated with fresh plasma for 1.5 h, its binding rate was 10.69%. Conclusion Its process of transportation in healthy rabbits is fitted to two-compartment model and the pharmacokinetic properties are desirable.
