Objective To compare the result of T2/T3 transitional cell carcinoma (TCC) of the urinary bladder after segmental cystectomy, treated by postoperative radiation plus intravesical chemotherapy and postoperative intravesical chemotherapy alone.Methods From 1985 to Dec.1995 patients with T2/T3 TCC bladder cancer who had been treated by segmental cystectomy were eligible for this retrospective analysis. Fifty-eight patients received postoperative radiotherapy plus intravesical chemotherapy (RT+IVC) and 35 patients were given postoperative intravesical chemotherapy (IVC) with thio-TEPA or calmette-Gue'rin bacilli (BCG). For radiation,8 or 18 ?MV X-ray was given with total dose of 50-60 ?Gy. Vesicoclysis was performed on 50-60 mg thio-TEPA twice per week and 0.5 mg BCG per week.Results The 3-year local control rates of RT+IVC and IVC groups were 68.6% and 48.2% showing a difference statistically significant (? 2=4.08,P=0.044).The 3- and 5-year survival rates of RT+IVC and IVC groups were 70.7%,49.5% and 59.9%,35.7% ,showing no significant difference (? 2=1.77,P=0.184). Among the 5 year survivors of the RT+IVC patients, 78.6% had their bladder preserved. Though untoward radiation reactions were severer, they were tolerated well.Conclusions Combined radiation therapy plus intravesical chemotherapy is indicated for T2/T3 bladder cancer after segmental cystectomy. Multimodality therapy is more favored to improve both the local control and the possibility of preserving the bladder.

Denture stomatitis is one of the most common problems appearing after patients wearing removable dentures,which appears more frequently in maxillary complete dentures. The clinical symptom is that the mucosa of the stress-bearing area of denture base broadly gets red,and forms the boundary diffusion erythema. Sometimes when the surface of denture base and the mucosa of stress-bearing area are not close well,some granules will be found at the surface of the erythema. With the world's gradually stepping into the aging society,the number of people who have to wear removable dentures is increasing,because dentition defect or edentulous affected by any reasons. As a result,how to solve the secondary disease such as denture stomatitis is becoming a hot spot which more and more researchers concern about. This paper summaries the development of prevention of denture stomatitis in prosthetic area via selection of base materials,manufacture of denture,sterilization of denture,and improvement of base.

AIM: To investigate the angiogenesis in the process of sarcoma 180 (S_(180)) tumor transplantation and changes of regulator factors, and explore the possible mechanism. METHODS: The S_(180) transplanted tumor in the Km mouse was used to detect the tumor angiogenesis by immunohistochemical examination of FⅧ. The levels of VEGF (V) and endostatin (E) in serum and the homogenate of tumor tissue were measured by ELISA and EIA, and the correlation between tumor weight and microvessel count (MVC) and morphology in tumor was also analyzed by multiple ANNOVA method. RESULTS: MVC, the relative count of total vessels and relative total vessel area increased with the development of transplanted S_ 180 . VEGF level in tumor tissue were higher at the 10th and 15th day than the 5th day after tumor transplantation. Endostatin in the tumor tissue and serum both reached the highest level at the 15th day, V/E ratio did not changed in this process. Furthermore, MVC, average vessel area and relative total area had a significant correlation with tumor weight. CONCLUSION: MVC increases in the development of S_(180) transplantation tumor and is related with the tumor weight; the positive regulator of angiogenesis in the tumor tissue is up-regulated during tumor growth, and the regulators in the tumor tissue maintains a relative balance.

Objective To study the effect of labeling esophageal carcinoma with sliver clips on two sides by esophagoscopy in mapping the target for conformal radiotherapy (CRT). Methods Eighty patients with esophageal carcinoma (28 patients in early stage, 52 patients in late stage), who were eligible for CRT, were collected and the tumor volume was detected by three methods: CT (A),CT combined with X-ray (B) and CT combined with sliver clip labeling by esophagoscopy (C). The differences of the tumor length and position in head-foot site (Y-axsis) among three methods were compared. Results The comparison of average length of tumor in early stage patients showed significant difference among three methods in all types of tumor (F= 4.07 ~ 7.43, P<0.05 ) except papillary type (F= 1. 71, P>0. 05). There was difference (ranged from 0. 5 cm to 2. 0 cm) in detection of position in head-foot site between A and B methods and C method. Significant difference was found in determining the displacement on head-foot site among three methods (F = 34. 36 ~193.50,P <0.01). The comparison of average length of tumor in middle or terminal stage patients showed significant difference among three methods in all types of tumor (F=4. 07~30.10 ,P<0.05) except mushroom type (F = 2.44, P> 0. 05). Significant difference was found in determining the displacement on head-foot site among three methods (F= 12.00 ~ 21.16, P < 0. 01 ). Conclusion These findings indicate that C method is more sensitive and correct in mapping the target for CRT in comparison with other two methods.
