Objective To study the clinical features,pathological characteristics and prognosis of renal cell carcinoma(RCC)in young adults,and to improve the recognition of RCC in young population. Methods The data of 35 young patients with RCC under the age of 35 years from August 1983 to June 2005 were analyzed retrospectively.There were 22 males and 13 females with a mean age of 31 years(age range, 19-35 years).The clinical presentations were as follows:painless hematuria in 12 cases(34%),low back pain in 12(34%),abdominal mass in 2(6%),fever in 3 and Stauffer syndrome in 1.The tumor size was 1.2-13.8 cm in diameter(mean,6.0cm).AJCC staging showed stage I tumor in 8 cases,stageⅡin 4, stageⅢin 18 and stageⅣin 5.Of the 35 cases,28 underwent radical nephrectomy(including simultaneous extraction of the vena cava emboli in 3 cases and extraction with pulmonary lobectomy in 1);5 cases under- went partial nephrectomy;and 2 cases lost the chance of operation(1 of them had biopsy).Results The operations were successful.The postoperative pathologic diagnoses consisted of clear cell carcinoma in 23 ca- ses,mixed cell carcinoma in 5,papillary cell carcinoma in 2,and chromophobe cell carcinoma in 2,low-dif- ferentiated and undifferentiated cell carcinoma each in 1.Of them,26 cases were followed for 12-148 months(mean,56 months).Postoperative 3-and 5-year survival rates were 65% and 50%,respectively. Conclnsions In young population,RCC is difficult to diagnose because of occult symptoms at early stage and lack of tumor specificity,which leads to relatively late clinical staging at diagnosis.RCC is characterized by higher malignancy,easy invasion to surrounding tissues and metastasis,and thus poor prognosis.

Objective To explore the value and the most reasonable procedure of EN by naso-intestinal tube in digestive tract disease after operation.Methods Data of 25 cases of indigestive tract disease subject to EN through a naso-intestinal tube after operation were reviewed and analysed.Results Insertion of naso-intestinal tube was completed in all cases.Nasal feeding could be completed in 24 cases;postoperative complications included 1 case of leakage,1 case of arrhythmia and heart failure and 4 cases of fat liquefication.Conclusion EN by naso-intestinal tube in digestive tract disease was favorable for reduction of postoperative risk.It could be applied in almost all pa- tients when the doctor had grasped the technique skillfully.

Objective To investigate therapeutic effects of muscle sliding operation treating Volkmann ischemic contracture of the forearm. Methods 32 cases Volkmann ischemic contracture were classified two types: the single type and the complex type. Three approaches were employed to treat different types which were single muscle sliding operation, muscle sliding plus skeletal operation, muscle sliding operation plus neurolysis.Results 29 cases were followed up, which excellent and good was 93.7 percent.Conclusions Muscle sliding operation was effective management for Volkmann ischemic contracture, and the skeletal operation or neurolysis could managed for the complex type in the meantime.

Objective To evaluate the clinical diagnostic value and limitation of MRI and contrast enhancement MRA (CE-MRA) in congenital heart disease of children. Methods Three hundred patients with congenital heart disease underwent CE-MRA. 173 were confirmed by operation. The results of MRA and CE-MRA were compared with operation data. Results 196 (86.0%) intracardiac malformation including septal defect and valve anomaly were diagnosed correctly by MRI within 228 abnormalities which were confirmed by operation. 101 (96.2%) extracardiac malformation including great vessels stenosis and anomalous connection were diagnosed correctly by MRI and MRA within 105 abnormalities which were confirmed by operation. Conclusion MRI and CE-MRA are very accurate diagnostic method for extracardiac malformation. CE-MRA is the best sequence for congenital heart disease.

Objective To report 6 cases of congenital heart disease with high origin of coronary artery and to evaluate the imaging method for diagnosis of congenital high origin of coronary artery. Methods Six patients with congenital high origin of coronary artery underwent angiocardiography ,echocardiography ,and 2 patients also underwent magnetic resonance examination. All 6 cases were confirmed by operation. Results All 6 cases were congenital high origin of right coronary artery. Angiocardiography made correct diagnosis in all 6 cases; MRI made the correct diagnosis in 1 of the 2 cases; echocardiography made 1 correct diagnosis. Conclusion Correct diagnosis of congenital high origin of coronary artery was very important for patients with congenital heart disease. Angiocardiography was a very reliable imaging method and MRI can play an important role in preoperative diagnosis of congenital high origin of coronary artery.

Abstract?AlM: To assess the efficacy and safety of trypan blue and indocyanine green ( lCG ) for continuous curvilineal capsulorrhexis ( CCC ) in mature or hypermature phacoemulsification.?METHODS: A total of 122 eyes of 122 cases with cataracts in mature and hypermature were randomly divided into three groups, trypan blue staining group was 46 eyes of 46 cases as group A, lCG staining group was 40 eyes of 40 cases as group B, control group was 36 eyes of 36 cases as group C. Staining groups were used to 0. 2mL trypan blue or lCG injected into the anterior chamber during operation, respectively. The success rate of CCC, lens posterior capsule rupture and implanted intraocular lens pouch were observed and compared during operation. Anterior chamber inflammation was observed after operation, and compared with the control group to observe and analysis.? RESULTS: The success rate of CCC, implanted intraocular lens pouch were statistically significant difference in trypan blue staining group ( group A ) than that in control group (group C) (P<0. 05). lmplanted intraocular lens pouch was statistically significant difference in lCG group ( group B ) than that in control group ( group C ) ( P<0. 05 ) . The rate of lens posterior capsule rupture was no statistically significant difference in all three groups ( P > 0. 05 ) . Anterior chamber inflammation was no significant difference in the postoperative reaction among the three groups.?CONCLUSlON:The application of trypan blue or lCG for lens capsule staining before CCC in lack of red reflective mature and hypermature cataracts is safe and effective, both results are comparable. lt guarantees a complete CCC and improves the success rate of phacoemulsification.

Objective To evaluate the feasibility and efficacy of minimally invasive percutaneous nephrolithotomy(MPCNL)in the lateral position.Methods A total of 48 patients with staghorn(12 cases,2.2 to 5.8 cm in diameter)or multiple renal calculi(31)or upper ureteral stones(5)were treated with MPCNL in our hospital between July 2004 to October 2007.The patients were placed in a lateral position with the head 10? lower and the feet 20? lower.The puncture was made under the guidance of X-ray or ultrasonography,and then Holmium laser or EMS lithotripter was used for stone fragmentation.The stone debris was removed by irrigation.Results The procedure was completed in all of the 48 patients except one,who was converted to a supine position because of the difficulty in puncture.Among the 47 cases,41 were cured with the first operation,the other 6 received catheterization in the first procedure,and then underwent calculi removal in a second-stage operation.None of the patients were converted to open surgery.The mean operation time in this series was(137.5?39.6)min.The one-stage cure rate in our patients was 82.9%(34/41).None of the cases had massive blood loss,or injuries to the pleura and other organs.Follow-up was available in 21 cases for 1 to 3 months.During the period,among the 17 patients who had hydronephrosis,11 were cured and 6 were improved;and among the 4 who had residual stones,1 received ESWL in 1 months after the first operation and was cured afterwards;the other 3 were treated by traditional Chinese medicine,2 of them were cured.Conclusions The MPCNL performed on the patients in the lateral position is an effective alternative for renal calculi,and favorable to intra-operative anesthesia monitor.

Objective To report 115 cases of congenital aortic arch anomalies, and to evaluate the imaging diagnostic techniques. Methods One hundred and fifteen patients with congenital aortic arch anomalies underwent angiocardiography and(or)contrast enhancement magnetic resonance angiography (CE MRA). Results In this 115 cases, double aortic arch was seen in 5 cases, right aortic arch with aberrant left subclavian artery in 45 with isolated left subclavian artery in 11, left aortic arch with aberrant right subclavian artery in 33, right aortic arch with left descending aorta in 7, left aortic arch with right descending aorta in 4, cervical aorta in 4, and others in 6. Conclusion CE MRA is a reliable noninvasive imaging diagnostic method.

Objective To evaluate MR findings and clinical features in patients with spontaneous spinal epidural hematoma (SSEH). Methods Eight patients (5 men, 3 women; aged 16-50 years ) with SSEH underwent MR imaging during 1994-2001, including 7 cases without history of trauma or coagulation disorders and 1 case with history of hypertension. MR imaging was performed from 4 hours to 3 days after the onset of symptoms in all 8 patients with surgical and pathologic diagnosis. Results The hematomas were in lateral posterior or posterior epidural space, including 3 cases in cervical vertebra, 2 cases in thoracic vertebra, 2 cases in cervical and thoracic junction region, and 1 case in thoracic and lumbar part. The MRI confirmed an encapsulated hematoma caused by arteriovenous malformation in 1 case and two hematomas associated with disc herniation. The signal intensity of the hematoma varied with the hematoma age, but T 1-weighted images reflected its typical signal changes. Sagittal and coronal T 1- weighted images revealed isointense (7 cases) and slight high-intense (1 case) signal; Sagittal and axial T 2-weighted images revealed mixed-intensity (6 cases) and mixed high-intensity (2 cases). Conclusion MR imaging has an important value on localization, identification, and differential diagnosis of the lesion, therefore, it is the most helpful diagnostic tool for this condition.
