Objective:To explore the clinical treatment and postoperative nursing experiences of penile urethral cavernous shunt and tunneling for low-flow priapism greater than 48 hours.Methods:Five patients with low-flow priapism longer than 48 hours underwent penile urethral cavernous shunt and tunneling after surgical contraindications were excluded. Postoperative medical care was closely coordinated through anticoagulation, antiandrogen and based on the theory of empowerment education Milk technology-encourage patients and their families to participate in disease management, using Milk technology to promote penile blood circulation, regularly assess the erection hardness of the penis, perform perioperative care, and try to restore penile cavernous arterial blood flow.Results:The operations were successfully completed. After treatment, the penis of the 5 patients was gradually weakened and the pain was relieved. They were discharged smoothly within 3 days of hospitalization, and all the abnormal erections were eliminated within 1 month after discharge. Follow-up for 6 to 12 months, 1 case was able to maintain Grade 3 erectile hardness and could complete sexual intercourse. One patient maintained Grade 2 erectile hardness. Three patients could only maintain Grade 1 erectile hardness and could not complete sexual intercourse.Conclusion:Penile urethral cavernous shunt and tunneling is safe and effective to treat low-flow priapism longer than 48 hours. Milk technology provides a new way to promote the recovery of blood circulation after penile surgery, which is worthy of further clinical promotion. These 5 patients with priapism have a long course of priapism, and the proportion of sexual function recovery is not high. The treatment of sexual function recovery needs further study.
大脑空间定位系统探讨了神经细胞参与空间定位的机制.该系统参与空间定位时,大脑不断收集周围环境的空间信息,构建脑内空间“地图”,指导空间定位和整合最佳路径.啮齿动物的空间定位信息主要来源于嗅觉、触觉和前庭感觉;不同于啮齿动物,灵长类动物和人类的空间定位信息主要来源于视觉,视觉捕捉和高分辨率的视觉成像在空间定位中的重要性不容忽视,且视觉信息可以增强空间认识感,视觉剥夺也会影响空间定位.本文主要综述了视觉与空间定位系统的联系以及视觉对空间定位的重要性.
A kind of mierosporidia was isolated from the infected larvae of Trichoplusia ni. The spores were oval in shape and (2.832±0.486)μm×(1.947+0.317)μm in size. Most tissues of T.ni could be parasited by the microsporidian.According to its developmental process it should be classified into genus Nosema,named as Nosema sp.
