Objective To evaluate the efficacy of post-operative radiotherapy and prognosis of renal cell carcinoma(RCC). Methods Between 1981 and 1998 , 90 s uch patients with disease limited to the kidney underwent nephrectomy at our ins titution. According to TNM classification(UICC,1997) the pathological stage was: Ⅰin 27 patients(30%),Ⅱ in 18 (20%), Ⅲ in 35(38.9%), and Ⅳ in 10(11.1%).Post - operative irradiation, with a median dose of 50?Gy in 25 fractions over 5 weeks w as given to 52 patients in 3～5weeks after surgery, using AP-PA opposing portal s or oblique portals. Results The 5- and 10-year survival rates in the irradiate d patients(S+Rt) were 75% and 60%,respectively, but in the non-irradiated patien t s(S) 50% and 40%, respectively.This difference is statistically significant. 5- y ear survival rates by TNM stage in the two groups were as follows: stageⅠ:S 67 %,S+Rt 100%;stageⅡ: S 55%,S+Rt 71%;stageⅢ: S 47%,S+Rt 65% (P=0 .010);stageⅣ: S 0%, S+Rt 43%.Diseases recurred locally in a total of 12 patients: 3 had tumo r b ed recurrence and 6 had regional lymph node recurrence and 3 had both. Local rec urrence in S was 29% and that of S+R was 2% (P=0.001). and local recurrence by T NM stage:Ⅲ were 33% and 5%, respectively. One patient developed radiation-indu c ed small bowel obstruction which necessitated surgical intervention, but no pat i ent died from radiotherapy-induced complications. By multivariate analysis: per f ormance status, symptomatic presentation, lymph node involvement, post-operativ e radiation and post-operative residual were all independent predictors of overa l l survival in the RCC patients. Conclusions In renal cell carcinoma, radiothera py is beneficial in reducing the locoregional recurrence. Radiotherapy has a sup prisingly positive effect on both local control and survival in TNM stage Ⅲ pat ients. Performance status, symptomatic presentation, lymph node involvement, pos t-operative radiation and post-operative residual are prognostic indicators of RCC. TNM staging is superior to Robson staging in predictive values .

Objective To observe clinical effects of compound Muniziqi granules combined with vitamin A acid cream, and analyze its mechanism of action.Methods 76 cases of patients with chloasma treated in our hospital in March 2010 to February 2014 were selected.They were divided into two groups according to random number table method, 38 cases in each group.Observation group was given compound Muniziqi granules( three times per day,orally) combined with vitamin A acid cream(smear once respectively each morning and evening),control group was taken vitamin C 0.3 g and vitamin E 0.2 g ( three times per day, orally ) comined with vitamin A acid cream ( smear once respectively each morning and evening ) treatment.Observed clinical effects, scores of lesion area and color, detected serum estrogen level in both groups by radioimmunoassay. Results Compared with pre-treatment lesion area and color scores of observation group significantly reduced ( P<0.05 ).Compared with control group post-treatment, lesion area and color scores of observation group significantly reduced(P<0.05).Clinical effective rates of observation group and control group was 94.74%and 75.31%, respectively, the difference was significantly between two groups(P<0.05).Compared with pre-treatment, serum E2, FSH, LH levels of observation group were remarkably reduced(P<0.05).Compared with control group post-treatment, serum E2,FSH,LH levels of observation group significantly reduced(P<0.05).Conclusion The clinical effect of compound Muniziqi granules combined with vitamin A acid cream on chloasma is significant.Its mechanism may be relate to levels of estradiol, follicle-stimulating hormone and luteinizing hormone.
