Objective To investigate the effect of ? 3-adrenoceptors(? 3-AR) on rat detrusor instability(DI) secondary to bladder outflow obstruction(BOO). Methods Animal models of DI were made in 15 female Wister rats.The filling cystometry was conducted after 6 weeks,and the rats were divided into DI group and detrusor stabitily (DS) group based on the detrusor function. The effects of ? 3-AR agonist BRL37344A on the frequency of contraction and relaxation response to isolated detrusor were examined by means of the in vitro detrusor strip study.And the expression of ? 3-AR subtypes mRNA was investigated in rat detrusor muscle by RT-PCR. Results The occurrence rate of DI was 67%(10/15).BRL37344A could inhibit the contraction frequence and amplitude of the isolated detrusor which was concentration-dependent.The intensity did differ significantly between normal controls or DS group and DI group.The relative contents of ? 3-adrenoceptor mRNA in DI group,controls and DS group were 10.27?3.54,19.84?2.62 and 18.38?1.95.There was a significant decrease in the concentration of ? 3-adrenoceptors in DI group compared with controls and DS group( P

To investigate the expression of ? adrenoceptors(? AR) and its possible function in rat detrusor. The relaxation response produced by ? AR subtypes(? 1 , ? 2 , ? 3 AR) agonists or antagonists were examined by means of the in vitro detrusor strip study, and the expression of ? AR subtypes mRNA was investigated in rat detrusor muscle by RT PCR. The selective ? 1 agonist T 0509, ? 2 agonist salbutamol, ? 3 agonist BRL37344A depressed the contractions of the detrusor muscle induced by KCl. The relaxant response to isoproterenol was antagonized by the ? 1 ,? 2 AR antagonists(100?mol/L) and the ? 3 AR antagonists SR59230(1?mol/L).RT PCR, showing that all three subtypes of ? AR subtypes mRNA were expressed in rat detrusor smooth muscles, in which ? 3 AR mRNA occupied 70%. All the ? 1 ,? 2 ,? 3 adrenoceptors participate in mediating relaxation of rat detrusor, among them ? 3 AR is the main one.

To investigate the role of ?and ? 3 adrenoceptors(? 3 AR) in rat detrusor instability secondary to bladder outflow obstruction(BOO). Animal models of detrusor instability were replicated in female rats, the relaxation response produced by ISO and ? 3 AR agonists BRL37344A were examined by means of in vitro detrusor strip study. ? and ? 3 adrenoceptors were detected in bladder specimens with radioligand binding assay. The concentrations of ISO and BRL37344A to produce relaxation were different in normal, stable and instable groups. There was a significant decrease in the density of ? adrenoceptors in the instable group compared with the controls and the stable group (66 23?6 39, 85 85?7 53, and 81 36?6 72 fmol/mg protein, respectively) ( P

Objective To investigate the molecular mechanisms of beta3 adrenoceptor subtypes mediating rat detrusor relaxation. Methods Cyclic adenosine monophosphate(cAMP) was detected by radioimmunoassay, the effects of the cyclic AMP inhibitor SQ 22,536 and the cyclic AMP dependent protein kinase inhibitor H 89 on the relaxation elicited by ISO and BRL37344A in the rat ditrusor were investigated based on pharmacological evaluations. Results After the stimulating of ? AR by ISO, the levels of intracellular cAMP was increased, and the relaxation mediated via ISO could be partly inhibited by SQ 22,536 or H 89 The concentrations of intracellular cAMP had no changes in the presence of SQ 22,536 or H 89, and the relaxant responses to BRL37344A was not affected by SQ 22,536 or H 89. Conclusion The effects of ISO via? AR on relaxant responses to detrusor was mediated mainly by the cyclic AMP independent pathway and in part by the cyclic AMP dependent pathway, but cAMP PKA pathway were not involved in the beta3 adrenoceptor signaling pathway

Objective To study the rule of lower-cervical lymphatic metastasis in thoracic esophageal carcinoma,and make evaluation about the reasonable extent of lymphadenectomy. Methods One hundred and eight cases of thoracic esophageal carcinoma through chromatic ultrasound and CT before operation were divided into different groups selectively,while three fields lymphadenectomy (3-FL) was adopted in 31 cases,and two fields lymphadenctomy (2-FL) was adopted in 77 cases. Results The rate of lower-cervical lymphatic metastasis was 87.1%(27/31) through chromatic ultrasound and CT,and that was 25.0%(27/108) before the two up-mentioned examinations (P<0.05). In all cases, the rate of lower-cervical lymphatic metastasis in the upper pectoral esophageal carcinoma was 47.6% (10/21),that in the middle pectoral esophageal carcinoma was 21.3%(13161),and that in the middle and lower pectoral esophageal carcinoma was 19.5%(17187) ,P<0.05. Through 3-FL, the rate of lower--cervical lymphatic metastasis in the upper pectoral esophageal eareinoma was 57.1%(12/21), that in the middle pectoral esophageal carcinoma was 23.0%(14/61), and that in the middle and lower pectoral esophageal carcinoma was 21.8%(19/87), P<0.05. Conclusions The regionality metastasis is the main fashion in thoracic esophageal carcinoma with lower-cervical lymphatic metastasis. It is feasible to judge lower-cervical lymphatic metastasis through chromatic ultrasound and CT before operation.The 3-FL of the upper pectoral esophageal carcinoma is recommended. The 3-FL is selectable in the middle and lower pectoral esophageal carcinoma according to the result of chromatic ultrasound and CT.

Objective:To analyze the clinico-pathological characteristics, pathological diagnosis, and treatment of rhabdoid tu-mor. Methods:The medical records of four rhabdoid tumor patients that were admitted to the Tianjin Medical University Cancer Insti-tute and Hospital since 2000 were analyzed based on existing literature. Results:In one of the four cases, the tumor originated from the kidney, whereas in the other three, the tumor occurred from extra-renal soft tissues. Histologic analysis revealed that the tumor cells were loosely arranged with diffuse growth, vesicular nuclei, dyed cytoplasm, visible eosinophilic inclusions, and more nuclear fission. The results of immunohistochemical staining showed that the vimentin and epithelial membrane antigen were positive, whereas CK, CD99, CD34, and S-100 were positive at different degrees. MyoD1, Desmin, and INI-1 were negative. Conclusion:Rhabdoid tumor is rare and highly aggressive. It occurs mainly in the kidney and can also be found in other systems. The unique pathological form and im-munohistochemical staining observed on the tumor can be used as reference for diagnosis.

Objective To investigate the safety and short-term effectiveness of the hybrid operation for the treatment of intracranial complex ruptured aneurysms.Methods From December 2014 to March 2017,14 consecutive patients with complex ruptured aneurysm treated with hybrid operation at the Department of Neurosurgery,Nanfang Hospital,Southern Medical University were enrolled retrospectively,including 13 with acute spontaneous aneurismal subarachnoid hemorrhage and 1 with hemorrhage in the recurrent aneurysm embolization.Twelve aneurysms were treated with shape clipping.Digital subtraction angiography (DSA) was used to evaluate the clipping effect of aneurysms.Two patients with aneurysm were treated with extracranial-intracranial (EC-IC) bypass and aneurysm trapping.Endovascular balloon occlusion for trapping aneurysms was performed after DSA evaluation of the patency of bridge vessel.Results Of the 14 patients,11 were treated with emergency hybrid operation after angiography,2 were treated with elective surgery,and 1 with emergency surgery for rescue because of bleeding during embolization.DSA revealed that the aneurysm clips in 3 of 12 patients needed to be adjusted,including 2 parent artery stenosis and 1 with incomplete clipping.After adjustment,the clipping was satisfactory.In intracranial and extracranial bypass surgery,angiography revealed that the blood vessels were patent.Trapping of the aneurysms was performed in the one-stage operation.One patient discharged voluntarily after procedure because of serious vasospasm.Onepatient had perfusion pressure breakthrough after surgery and received hematoma evacuation and decompression.The Glasgow outcome scale (GOS) score was 3 at discharge.Other patients had no new neurological dysfunction after operation.Thirteen patients were followed up for 3-24 months after operation.There were no new neurological dysfunction,including GOS 5 in 8 cases and 4 in 5 cases.Six patients underwent DSA examination,in 4 of them the aneurysm clipping did not show aneurysm recurrence,and the parent arteries were patent.Two patients treated with vascular bypass.There were no recurrence of aneurysms,and the parent arteries and anastomotic vessels were patent.Conclusion After preliminary observation,using hybrid operation for the treatment of complicated intracranial ruptured aneurysms was safe and effective.
