Objective To compare the tannin contents of Platycladus orientalis(L.) Franco and its carbonisatus.Method A tungsten molybdophosphate-casein colorimetric method was used with gallic acid as reference substance.Results The standard curve in the range of 0.026~0.26 mg(r =0.999 4),and the average recovery rate was 97.85%,RSD=1.07%(n =9).Conclusion The method is reliable and can be used to determine the tannic of and its different processed products.

Angiotensin (Ang Ⅱ),a main effector peptide of the renin-angiotensin system (RAS),mediates a hormonal action in the maintenance of blood pressure and electrolyte levels,and thus fluid homeostasis.Recent studies have implicated that it correlates with tumor growth,angiogenesis,metastasis and it has drawn more and more attention.Many studies show that Ang Ⅱ-AT1R/AT2R play crucial roles in tumor growth,metastasis,invasion and tumor angiogenesis,which are formed new targets for treating malignant tumors.

Objective:
To assess value of immediate postoperative intravesical instillation of pirarubicin after transurethral resection (TURBT)of non-muscle invasive bladder cancer.
Methods:
484 patients diagnosed with non-muscle-invasive bladder cancer admitted to the Second Affiliated Hospital of Kunming Medical University were divided into two groups after transurethral resection of bladder tumor. 285 patients received postoperative intravesical instillation of pirarubicin within 6 hours after the surgery, 199 patients received first instillation of pirarubicin at 10 days after the surgery, after that, all the patients received routine bladder perfusion chemotherapy. Patients who received intravesical instillation of pirarubicin within 6 hours were defined as immediate intravesical instillation group and the other patients as the control group. Based on the European Organisation for Research and Treatment of Cancer risk tables, scores of recurrence and progression of patients were calculated and then stratified into risk groups accordingly. Recurrence and progression rates of the immediate intravesical instillation group were analyzed and then compared with the corresponding reference of the risk tables.
Results:
The 1-year and 5-year recurrence rate of patients with EORTC table scoring 0 in the immediate intravesical instillation group were significantly lower than that of the EORTC reference group (5.3% and 14.0% vs 15.0% and 31.0%,
