Objective To evaluate the clinical characteristics, diagnosis and treatment procedures for adrenal pheochromocytoma and adrenal ganglioneucoma.Methods Thirty-two cases of adrenal pheochromocytoma and 14 cases of adrenal ganglioneucoma surgical treated between 1999—2005 were analysed, The average of ganglioneucoma was 39 years old (16~63). tumor size ranged from 2.5 cm to 15 cm. The mean age of pheochromocytoma was 42 years old (19~74), tumor size ranged from 2cm to 16 cm. Tumor located in the adrenal area. All cases accepted surgical operation and were confirmed by pathology. Results Most cases of adrenal ganglioneucoma did not have any symptom but were founded incidentally. Differentials were obviously between ganglioneucoma and pheochromocytoma. Conclusion Both adrenal ganglioneucoma and pheochromocytoma are rare diseases.CT、urinary CA and 131I-MIBG are good methods for diagnosis.The final diagnosis depends on the pathology, surgical resection of tumor is a preferred choice.

Chinese Journal of Digestive Endoscopy 1996;0(05):-
Objective To investigate the role of endoscopic nasobiliary drainage ( ENBD) of bile duct instead of T tube drainage during laparoscopic common bile duct exploration (LCBDE). Methods All the patients accepted ENBD before LCBDE / laparoscopic cholecystectomy (LC) + LCBDE. During the operation the stones were extracted by choledochoscopy or crashed with electrohydraulic lithotripsy. After removing all of the biliary stones, the nasobiliary tube still remained in the common bile duct, then primary closure of the exploration wound on the duct wall was made, and with routine abdominal drainage. After operation , radiography of the nasobiliary tube was taken to investigate if there were any residual stones or leakage in the bile duct remained. Subsequently the drainage tube and nasobiliary tube were respectively removed as indicated. Results Totally 43 cases accepted ENBD preoperatively, after 6. 1 days LCBDE was performed, in 36 cases (83. 7% ) the operation was successfully using nasobiliary drainage and primary closure of the duct wound. Postoperative radiography of the duct system through the nasobiliary tube showed only in one case (2. 6% ) a small stone left which was then extracted under ERCP. There were no bile duct stricture and bile leakage, so the nasobiliary tube was removed smoothly. Seven cases ( 18. 6% ) were transferred to open abdominal exploration, 2 of them still kept the nasobiliary tube and the choledochal incisions were primary closed. Totally 38 patients (88.4% ) were successfully drained by ENBD. The abdominal drainage and nasobiliary tubes were removed in average of 3.2 and 6.7 days respectively without complications. Conclusion ENBD is an effective and safe procedure for bile duct drainage in LCBDE. It has the advantage of minimal trauma, short drainage period and rare complications. It suggested that this procedure should be a new satisfied way in treatment of bile duct stones.

Objective To investigate the dosage, efficacy and safety of intravitreal injection of plasmin in producing posterior vitreous detachment (PVD), and the possible role of plasmin in degrading adhesion glycoproteins of inner limiting membrane (ILM). Methods Twenty eyes of young human cadavers within 24 hours after death were divided into 4 groups that received 0 1 ml balanced salt solution (group 1) as control, 1 (group 2), 2 (group 3), or 3 (group 4) U of human plasmin. Optical and transmission electron microcopies were performed to examine the ultrastructure of the vitreoretinal interface. Electron immunocytochemical techniques were carried out on ILM to estimate the content of fibronectin (FN) and laminin (LN). Flow cytometry was used for cell viability analysis of variance (ANOVA) and Tukey test was employed for statistical analysis. Results Microscopy demonstrated that plasmin especially in group 4 cleaved the attachment of the vitreous collagen fibrils to the ILM with no evident damage to the inner retina. The content of LN, FN in ILM decreased with injection of plasmin (group 3 and 4 had statistical significance from control group for FN, P

Objective To explore the relationship of thyrotropin receptor antibody (TRAb) and soluble intercellular adhesion molecule-1 ( sICAM-1 ) in patients with thyroid-associated ophthalmopathy ( TAO), and the role played by TRAb and sICAM-1 in the pathogenesis of TAO. Method Twenty-three TAO patients were assigned to groups according to the clinical activity score and EUGOGO. All patients were treated with intravenous methylprednisolone pulse. The levels of serum TRAb and sICAM-1 were evaluated by a competitive radioimmunoassay and enzyme-linked immunosorbent assay respectively before treatment and by the end of each methylprednisolone pulse. Results The differernce in serum TRAb levels was associated with activity scores of TAO (P=0. 020). The change in serum sICAM-1 was associated with durations of TAO ( P = 0.015). During methylprednisolone treatment in active TAO patients, the levels of TRAb kept on decreasing gradually and markedly declined after the third methylprednisolone pulse in active TAO patients (P<0.05). The trends of changes in serum TRAb and sICAM-1 levels were both different in active and inactive TAO patients by tendency analysis. Conclusion TRAb level was related to the activity of TAO and might serve as a significant predictor of response to methylprednisolone therapy. The negative correlation between sICAM-1 levels and duration of TAO corroborates the role played by ICAM-1 during the early stage of TAO. Higher sICAM-1 levels are not expected to be specific to TAO and may not predict a response to methylprednisolone therapy.

Objective To identify the suitable echocardiographic predictor,the standard 2-demensional echocardiography and speckle tracking imaging (STI) techniques were applied for the late referred children with transposition of great arteries with intact ventricular septum (TGA-IVS) after neonatal period.Methods 22 children with TGA-IVS after neonatal period were enrolled.According to the intraoperative left ventricular (LV)/right ventricular systolic pressure ratio,they received pulmonary artery banding (PAB group,n =10) or arterial switch operation (ASO group,n =12).15 body surface area matched healthy children were served as control group,Echocardiography was performed before the operation.The dynamic images in basal and apical short axis view were collected respectively.Meanwhile,using the STI technique,the rotation curves at apex and base was analyzed.Results All the patients discharged eventually.A right to left bulging of the ventricular septum was observed in all the patients by the 2D short-axis view.There were no differences in wall thickness and ejection fraction between control,PAB and ASO group.Compared with the control group,the end diastolic diameter,end diastolic volume and indexed LV mass in PAB and ASO group were significantly reduced,however,no difference in the end diastolic diameter and volume and LV mass was observed between the PAB and ASO group.The hypoplasia of LV in PAB and ASO group was associated with an extended time to peak basal rotation and reduced basal rotation and global torsion.Furthermore,the shorter time to peak apical rotation and reduced apical rotation and global torsion were only observed in PAB group.Conclusions The standard echocardiography could be useful for the initial evaluation for regressed LV of the children with TGA-IVS.However,STI allows a much more precious approach to the assessment of LV regressing after neonatal period.The apical rotation and global torsion might be the better predictor to identify the borderline or regressed LV for the surgical management for the children with TGA-IVS.
