Objectives To evaluate the relationship between phaeochromocytoma and renal cell carcinoma,and to present 2 cases of coexisting phaeochromocytoma and renal cell carcinoma. Methods 2 cases of coexisting phaeochromocytoma and renal cell carcinoma diagnosed and treated were reviewed and studied. A case of left adrenal phaeochromocytoma was disdiagnosed as metastatic carcinoma from the left kidney.Nephrectomy and adrenalectomy were carried out without preoperative preparation crisis occurred in the operation and was managed in time.The another is a case of coexising right adrenal phaeochromocytoma and right renal cell carcinoma.After adequate preoperative preparation,the operation was carried out safely.The postoperative course of both the patients has been uneventful. Conclusions An adrenal growth on the same side of a renal cases may not be a metestatic carcinoma.The possibility of an coexisting phaeochromocytoma shuld be kept in mind.Surgical management was the only means for cure and preoperative preparation was extremely important.

Objective To explore a best operative method in order to improve operative manipulated skill of simultaneous pancreas-kidney transplantation(SPKT),a model of SPKT was established in dogs.Methods 12 dogs of SPKT were performed in animal model.A renoportal end-to-end anastomoses between the renal and the spleen vein.Only two vascular end-to-side anastomoses between the donor portal vein and recipient ilio-vein,and between the donor celiac arteries and recipient abdominal aorta were constructed.Pancrease was placed in the right iliac fossa and kidney in the left.Pancreatic exocretion goes through bladder drainage.Results Combined resection was successfully performed in 6 dogs and the other underwent simultaneous pancreas-kidney transplantation.Satisfactory result was obtained in 5 survival dog for a mean of (1 5?0 8)days,although 1 dog died from hypopiesis.Conclusions The model is practically feasible and might be used in studying the problems involved in SPKT,which is effective for the treatment of end-stage diabetic nephropathy.

Objective To study the radiation effects on the serum concentration of urea nitrogen (BUN), creatinine (Cre), ?2-microglobulin (?2-MG) and uric acid (UA), and to evaluate the injuries to renal function induced by a 60 Co irradiation accident in Shandong province. Methods The concentrations of urea nitrogen, serum creatinine and serum uric acid were determined by enzymatic methods. The concentrations of serum ?2-microglobulin were determined by the immunoturbidity methods using HITACHI 7170s automatic biochemical analyzer. Results The serum concentrations of BUN and Cre of 2 patients increased significantly after irradiation, and the serum concentration of UA in the two cases elevated too after irradiation, but didn't reach the normal value. The serum concentrations of ?2-microglobulin also increased significantly after irradiation. In case A which received 20~25Gy irradiation, the concentrations of serum BUN, creatinine and ?2-microglobulin increased to 41.63mmol/L, 364?mol/L and 9.2mg/L, respectively. In case B which received 9~15Gy irradiation, the concentration of serum BUN, creatinine and ?2-microglobulin increased to 52.2mmol/L, 199?mol/L and 11.3mg/L, respectively. There seemed a dosage-dependent effect on the BUN, Cre and ?2-microglobulin concentration. Conclusion 60 Co may irradiate the tissues of kidney directly, and irradiate the cells of other tissues and organs, lead to necrosis and degenerations accordingly on the tissues of kidneys and other organs. In the process of necrosis and degenerations, a large amount of metabolic products was released which is poisonous to the kidney. The present results showed the concentrations increased of all the four renal serum markers mentioned above. It is supposed that the renal cells might be damaged by the Cobalt ? ray irradiation.

The structure determination was based on spectral (UV, IR, 1H & 13CNMR and MS) and chemical evidence. RESULTS: Its structure was characterized to be 7-O-galloyl-D-sedoheptulose (I). The proportion of its three major conformation forms of β-F, α-F and α-P in aqueous solution was estimated to be 57:24:19 according to their C-1 peak heights in the 13CNMR spectrum. CONCLUSION: I was found in natural world for the first time and its β-D-heptufuranosyl form was the predominant existing tautomer in its equilibrated aqueous solution according to NMR determination.

Objective To evaluate the clinical value of laparoscopy in adrenal surgery.Methods From December 2000 to May 2006,86 cases of adrenal space-occupying lesion received laparoscopic adrenalectomy via transperitoneal(n=1),retroperitoneal(n=81) and hand-assisted transperitoneal(n=4) approach,respectively.Results All the operations were successful without conversion to open surgery and severe complications.The mean operative time was 72 min(range,50-175 min).The mean blood loss was 54 ml(range,15-120 ml).The postoperative hospital stay was 6.3 d(range,5-8 d).Imaging examinations revealed no tumor recurrence and metastasis during the mean follow-up period of 26.5 months(range,2-65 months)in 86 patients.The symptoms of patients with functional tumor was alleviated or disappeared.Conclusions Laparoscopic adrenalectomy has advantages of minimal invasion,less blood loss,and quicker recovery,and it should be the fist choice for most adrenal space-occupying lesions.

Objective Evaluated NOS expression in bladder tissue from the patients with transitional cell carcinoma (TCC) of the bladder and studied its relationship with angiogenesis. Methods Bladder carcinoma tissue specimens were procured from 58 patients with TCC and 14 cases of benign bladder tissue as contrast group. NOS immunohistochemistry was performed on all tissue specimens and microvessal density (MVD) was counted by endothelial cells immunostained. Results Inducible NOS specific proteins were found in 47 of 58 bladder cancer specimens but not in control bladder tissue. The malignant cells and inflammatory cells within the carcinomas were highly iNOS positive whereas specimens of bladder mucosa outside the malignant regions showed only a weak positive iNOS immunostaining. The endothelial cells in both normal urothlium and tumor tissue showed a highly positive eNOS immunostaining but its immunoreaction was not detected in either malignant or benign epithelium. MVD was (39.3?19.5)/HP and (29.3?10.5)/HP in iNOS positive and negative tissues respectively (P

Objective: To analyze the role of frequency complemcntarities of vestibular tests including caloric test (CT),head shaking test(HST),and vibration test(VT) in the evaluation of vestibular function. Methods: Five hundreds and eightyfour patients with unilateral peripheral lesions were tested with CT, HST and VT in order to compare the frequency characteristic of abnormal vestibular function. Results: Of the 584 patients, 189 (32.36%), 283 (48.46%) and 368 (63.01%)cases showed vibration-induced nystagmus (VIN), head shaking nystagnms (HSN) and abnormal unilateral weakness (UW)respectively. There were 22 isolated VIN, 52 HSN and 145 cases of abnormal UW respectively. One hundred and fifty-nine (27.23%) cases had combination damage of two frequency bands, 101 (17.29%) had vestibular damage at all frequency bands,479 (82.02%) had abnormal results in any of the three tests, and 105 (17.98%) had no abnormality in all those three tests.Through consistency test, CT and HST (Kappa=0.106, P＜ 0.05), CT and VT(Kappa=0.068, P＜ 0.05), VT and HST (Kappa=0.321, P＜0.05) showed low consistency among them. VIN and HSN were more hkely to be evoked with the increasing of the UW (X'2VIN=22.686,X2HSN=23.023, P＜ 0.05). Conclusion: The vestibular damage in the patients with vertigo could reflect at isolated low, middle, high frequency or multi frequency bands. Thus, CT, HST and VT all make significant contributions to multiple-frequency analysis of vestibular function and show a well complementarities. So they can be used in evaluating the overall function of the vestibular and indicating a serious vestibular lesion if the damage affected multi frequency bands.
