Methods: Sixty-four cases of patients advanced colorectal cancer from August 2004 to February 2008 were selected for radical surgery, including 32 cases injected with intraoperative fluorouracil controlled release formulation in local implantation for 600 mg (the treatment group). Patients in another 32 cases received abdominal washing surgery by distilled water (the control group). All patients were followed up for 2 years and observed in aspects of the toxicity, 2-year survival rate, local recurrence rate and distant metastasis rate. Results: The 2-year survival rate and local recurrence rate in the treatment group was better than those in the control group (P < 0.05); as for toxicity and distant metastasis rate, no significant difference was observed. Conclusion: The effect of fluorouracil controlled release formulation in local implantation treatment was significant and the patient tolerance was satisfactory. Thus, it is an effective approach in the treatment of advanced colorectal cancer.展开更多

Among its various chemical constituents,(-)-hinokinin, a trypanosomicidal dibenzylbutyrolactone lignan, is found in significant quantities.For quality evaluation of P. cubeba fruit and its commercial formulations, there is an urgent need to develop an analytical method based on(-)-hinokinin. For this purpose, an HPLC method was developed using photo diode array detector and Waters HR C18 column with gradient elution consisting of water and acetonitrile. The developed method was validated as per ICH-Q2 B guidelines and found to be accurate, precise and linear over a wide range of concentrations(5–300 mg/m L).(-)-Hinokinin contents were found to be in the range of 0.005–0.109%(m/m) in various P. cubeba samples. The developed method was extended to LC–MS for further identification and characterization of(-)-hinokinin in samples. The developed method is simple,rapid and specific, and can be used as a tool for quality control of P. cubeba fruits and its commercial formulations.展开更多
