Objective To assess the outcomes of modified spiral ileal orthotopic neobladder.Methods From January 1998 to January 2008, 32 patients (all male) underwent radical cystectomy and spiral ileal orthotopic substitution for muscle invasive bladder cancer. A segment of 40 to 45 cm ileal loop was isolated, detubularized, and reconfigured in spiral shape to form a pouch. Bilateral ureters were reimplanted by inserting the 1 cm distal segment into the pouch to form a Split-Cuff nipple.The bottom of the pouch was opened and anastomosed with the urethra (4 stitches). Results There were no perioperative deaths. The mean operative time was 281.2±48.7 min. Blood loss was 545.4±181.9 ml. Twenty cases required a blood transfusion, the mean volume of intraoprative blood transfusion was 430.8±235.9 ml. The average hospital stays were 26.8±9. 7 days. Rate of daytime continence was 93. 7% (30/32) while nighttime continence was 81.3% (26/32). Urodynamic studies were carried out in 23 cases 6 months after surgery. Neobladder capacity at first desire to urinate was 315.0± 33.4 ml(270-420 ml). The maximum neobladder capacity was 490. 3±39.7 ml(350-600 ml).The maximum flow rate (Qmax) was 16.5 ± 5.9 ml/s. Full resting pressure was 22. 5 ± 11.8 cm H2O. Peak voiding pressure was 78.3 ± 14.7 cm H2O. After mean 58. 4 months' follow up (range 22 to 132), 4 cases died of metastasis of bladder cancer. Conclusion Modified spiral ileal orthotopic neobladder is a reasonable option for treating invasive bladder cancer.

BACKGROUND:Previous studies have shown that kainic acid injected into hippocampus can significantly upregulate the expression of excitatory KA1 subunit of the kainate receptor in the hippocampus, and endoplasmic reticulum stress markers, phosphorylation of the alpha subunit of eukaryotic initiation factor 2, accompanied by celldeath. OBJECTIVE:To explore the mechanism of endoplasmic reticulum stress after kainic acid is injected into the hippocampus.METHODS:0.15 nmol kainic acid was injected into the hippocampal CA1 region of 32 adult male Kunming mice, the injection time was 60 seconds. At different time points (1, 2, 3, 4, 5, 6, 8 and 12 hours) after kainic acid was injected, the Bederson score analysis was performed, and then the brain was harvested after cerebral perfusion. FJB staining of brain sections and immunofluorescence double labeled observation were also performed. RESULTS AND CONCLUSION:(1) At 3, 4, 5, 6, 8 hours after kainic acid injection, Bederson score showed severe injury of central nervous system function, and FJB staining showed the increased of celldeath in the hippocampus (P<0.05);At 1, 2, 12 hours after injection, Bederson score showed no obvious injury of central nervous system function, and FJB staining showed unobvious celldeath in the hippocampus (P>0.05). (2) According to the results of FJB staining, the brain sections were selected at 3, 8 hours for immunohistochemistry. The expressionlevels of KA1 receptors and endoplasmic reticulum stress marker P-eIF2αwere up-regulated at the same time after kainic acid was injected into hippocampus. Two single-staining KA1 and P-eIF2αimmunofluorescence images were synthesized into one over-lapped double-stained image, and two images overlapped, indicating that the up-regulated expression of KA1 and endoplasmic reticulum stress occurred in the same nerve cells. Kainic acid first up-regulated the excitatory receptor KA1 expression, which may cause cellendoplasmic reticulum dysfunction and result in the endoplasmic reticulum stress response, further promoting neuronal celldeath.

Objective To study the expression of Ca-A/K channel-related molecules glutamate receptor 2 and 1(GluR2/1) in hippocampus tissues of neonatal rats with hypoxic-ischemic brain damage (HIBD). Methods A total of 60 7-day-old Sprague-Dawley rats were randomly divided into sham operation group and HIBD group. Hippocampal tissues were obtained at 0 h, 1 h, 6 h, 24 h, 48 h and 72 h after HIBD. The expression of GluR2, GluR1 and autophagy marker protein Beclin-1, LC3 were detected by Western blot assay. Results Edema and focal softening and necrosis were observed 6 h after HIBD in the brains of neonatal rats. Compared with Con group, at each time point, the expression levels of GluR2 were lower while the levels of GluR1, Beclin-1 and LC3 were higher significantly in HIBD group (P<0.05). The protein levels of LC3, Beclin-1, GluR1 and GluR2 in hippocampus tissues of HIBD group were significantly different among different time points after the estab-lishment of HIBD model (F=10.65~701.14, P<0.01). The protein level of GluR2 was decreased from 1 h to 24 h after HIBD and reached the lowest level at 24 h. The levels of GluR1, Beclin-1 and LC3 were increased at 6 h, plateaued at 24 h and remained there until 48 h. The levels of these proteins returned back to the initial level at 72 h. Conclusions Ca-A/K channel-related mol-ecules GluR2 and GluR1 play important roles in the autophagic cell death of hippocampus tissues in neonatal rats with hypoxic-ischemic brain damage.
