Background and purpose:Brucine is one of the active components from Strychnos nux vomica,with signifi cant analgesic,anti-inflammatory and platelet-aggregating inhibitory properties.Due to its cytotoxic effect,the anti-tumor effect of brucine has increasingly been appreciated.In this study,we investigated the impact of brucine on A549 cells proliferation,apoptosis as well as the underlying mechanisms.Methods:MTT assay was used to examine the cell viability,flow cytometric analysis and fluorescent microscope were applied to examine cell apoptosis,ELISA method was used to examine the effect of brucine on PGE2 release from A549 cells and RT-PCR analysis was used to measure mRNA content,western blotting analysis was used to measure protein expression and luciferase activity was detected to examine the effect of brucine on COX-2 promoter activity.Results:Brucine was able to suppress the proliferation of A549 cells and induce cell apoptosis to time-dependent and dose-dependent manner.To understand the mechanisms,COX-2 was identifi ed to be an important target molecule involved in the apoptosis induced by brucine because brucine could suppress the COX-2 mRNA,protein expressions as well as PGE2 release in A549 cells in a timedependent manner.Furthermore,overexpression of COX-2 abrogated brucine-induced cell apoptosis,in contrast,when A549 cells were transfected with COX-2 siRNA,the apoptotic effect of brucine was dramatically enhanced.Further analysis revealed that brucine was able to suppress COX-2 transcriptional activation.Conclusion:Brucine was able to induce lung cancer apoptosis via downregulation of COX-2.

Objective To explore the effect of prospective nursing on preventing constipation for patients with acute myocardial infarction(AMI). Methods 43 AMI patients during July 2008 and June 2010 in our hospital were classified as the observation group, besides the nursing routine of the acute myocardial infarction plus routine therapy to prevent constipation, prospective nursing was implemented.Through the retrospective analysis of medical record, 41 of AMI in our hospital during March 2006 and June 2008 were classified as the control group, they were given the nursing routine of the acute myocardial infarction plus routine therapy to prevent constipation and the nursing intervention after occurrence of constipation. The defecation condition was assessed for the two groups of patients on admission and the defecation and mortality rate was compared on the eighth day of hospitalization. Results There was significant difference in constipation and mortality rate between the two groups of patients during hospitalization. Conclusions The prospective nursing for AMI patients to prevent constipation can obviously reduce the incidence of constipation, thus to avoid serious complications caused by constipation and reduce mortality.

This study was conducted to assess the effects of over ten years of antihyper-uricemic follow-up therapy on 65 patients out of 118 cases of primary gout. It was found that reduced tophaceous deposition correlated with normalization of the serum uric acid concentration. The patients with lower mean uric acid concentrations were more likely to have a reduction in tophi. There was a lack of correlation between mean serum uric acid concentrations and radiographic changes of gout. Although treatment allowed better control of the disease in general, serum uric acid concentration alone may not provide an effective means of monitoring the progression of the disease. In this series,antihyperuricemic agents were generally well tolerated. Gastrointestinal upset was seen in 13 of the 65 cases (20%),mild leukopenia in 6 patients. skin rash in 2 and herpes simplex in 1. No patient was withdrawn from the therapy owing to the untoward side effects.

Objective To evaluate the effect of concomitantdifferent regimens chemotherapy and radiotherapy for inoperable stage Ⅲ non small cell lung cancer (NSCLC). Methods From September 1995 to December 1998, 62 patients with inoperable stage Ⅲ NSCLC were randomized into two groups. Twenty nine patients received paclitaxel 30 mg and cisplatin 30 mg weekly for 5~6 weeks (paclitaxel group), and 33 patients received etoposide (Vp 16) 100 mg and cisplatin 30 mg weekly for 5~6 weeks (VP 16 group). All patients received concomitant radiotherapy as well. Radiotherapy was given with conventional fraction in 2Gy per fraction and five fractions per week. The total tumor doses were 60~70 Gy. Treatment fields covered clinical tumor and lymph node involved. Results The overall response (CR+PR) rate in paclitaxel group was 82.8% with a complete response (CR) rate of 10.3%. The overall response rate in the VP 16 group was 54.6% with a CR rate of 18%. The difference of overall response rate between the two groups was statistically significant (P0.05). The major toxic effects of chemotherapy were gastrointestinal tract reaction and myelosuppression. Conclusions Concomitant chemotherapy of paclitaxel plus cisplatin and radiotherapy for inoperable stage Ⅲ NSCLC is acceptable, and its efficacy is superior to cisplatin plus etoposide combined with radiotherapy.
