This study will detect the expression of neurexophilin 1 gene in the epithelial cells of the UVJ, DF-1 cells and Hela cells, aims to look for convenient cells when studying the function of neurexophilin 1 gene in chicken genital tract.
Neurons and small ganglia were identified in the UVJ of the turkey and chicken oviduct, and nerve fibres appeared to terminate on individual sperm storage tubules (Freedman et al., 2001), suggesting that neural factor may regulate sperm storage in and release of spermatozoa from the SST of hens.
Expression of neurexophilin 1 gene in adult chicken UVJ was corresponded to fertility (Liu et al., 2009).
The expression of neurexophilin 1 gene was elevated in the UVJ of high fertility hens (Liu et al., 2009).
The movement of the UVJ is 5.1mm for the healthy support system in our study which is in good agreement with the MRI examination (5 mm) of a nulliparous (asymptomatic or healthy or continent) female without tissue impairment .

Early transient obstruction is frequently due to edema of the UVJ. On the other hand, persistent obstruction is often due to stenosis or kinking of the ureter and may need a repeat reimplantation.
Conclusion: The assessment of color Doppler pattern of ureteric jet flow at the UVJ is valuable in the diagnosis of nonobstructive nephrolithiasis.
Treatment modalities of ureteral strictures Treatment modality N=25 n Surveillance 3 Balloon dilation +/- ureteric stent 3 Laser endoureterotomy +/- balloon 8 (2 required multiple dilation endoscopic procedures) Transurethral resection of UVJ + 1 ureteric stent Nephrectomy (MIS/open) 2 (1 after failed endoureterotomy) Open ureteroureterostomy 2 (1 after failed endoureterotomy) Open ureteral re-implant 3 (1 after failed endoureterotomy) Urinary diversion 3 Ileal conduit 1 Indiana 1 (after failed ureteral reimplant) Nephroureterectomy + ileal conduit 1 Autotransplant 1 Ongoing chronic stent changes 4 MIS: minimally invasive surgery; UVJ: ureterovesical junction.
CCEG is a benign inflammation of the bladder, characterized by von Brunn's nests that grow into the lamina propria forming cysts and/or metaplastically changing into goblet cells.[sup.1] Although a common incidental finding in many bladder investigations, CCEG is usually asymptomatic.[sup.4] There have been previous documented cases of CCEG causing obstruction, reminding us of a rare but potentially important cause for obstruction.[sup.3]-[sup.5] We believe this is the first reported case of recurrent CCEG causing obstruction of the UVJ leading to hydronephrosis and acute azotemia.
Ureteroscopy confirmed that there was no physical obstruction of the distal ureter and UVJ. The distal ureter was voluminous immediately above the intramural segment, and proximally it tapered to normal calibre.
