OBJECTIVE: To observe the protective effects of Corydalis ambailis migo total alkaloids (COAMTA) on cerebral ischemia/reperfusion injury in rats and to investigate its mechanism. METHODS: The effects of COAMTA on decapitated gasping mouse model and rat model of middle cerebral artery ischemia (2 h)/reperfusion (22 h) were observed. The neurological scale, cerebral infarcted volume and cerebral water content subjected to cerebral middle artery ischemia/reperfusion in rats were recorded. The activities of nitric oxide synthase (NOS) and superoxide dismutase (SOD) and the content of malondialdehyde (MDA) in the ratso brain were measured. Cell apoptosis in ischemic penumbral area was observed with light microscope in the method of terminal deoxynucleotidyl transferase mediated dUTP-biotin nick end labeling (TUNEL). RESULTS: The average gasping time of the mice (6.0 mg/kg or 9.0 mg/kg COAMTA) was significantly prolonged, the cerebral infarcted volume and cerebral water content of the rats (5.0 mg/kg or 7.5 mg/kg COAMTA) were significantly decreased, as compared with the control groups. The average activity of SOD in cerebral tissue of the rats (5.0 mg/kg or 7.5 mg/kg COAMTA) was significantly higher than that of the control groups, meanwhile, the average activity of NOS and the content of MDA declined significantly. The cell apoptosis in ischemic penumbral area of the rats (5.0 mg/kg COAMTA) was significantly inhibited as compared with the control groups. CONCLUSION: COAMTA can facilitate the protection against cerebral ischemia/reperfusion damage. The mechanism is related to inhibiting the activity of NOS and lipoperoxidation, increasing the activity of SOD and decreasing the neuronal apoptosis.

Background and purpose:The prognosis of high grade gliomas remains poor, and multidisciplinary treatment strategy has been much investigated recently. This study was to explore the efficacy of Temozolomide as first-line treatment combined with radiotherapy and followed by adjuvant chemotherapy for the treatment of newly diagnosed high grade gliomas. Methods:18 patients who had been pathologically proven to be high grade gliomas were enrolled into the study. The patients received 40 Gy/20fractions for the whole brain and followed by 20Gy/10fractions as a boost to tumor bed. All of the patients were given daily oral temozolomide 75mg/ m2 during radiotherapy. 4 weeks after radiotherapy, all of the patients received 6 cycles of Temozolomide, each cycle lasted 5 days with 28 days interval between each cycles. 150 mg/m2 of temozolomide was given for the first cycle for five days,followd by 200 mg/m2 of drug for the rest of the cycles if no significant drug related toxicities were observed. Results:Median follow-up was 12.5 months, 11 cases had either recurrence or progression, 5 of them died from the disease. The median time for disease progression-free survival was 9.8 months (95% CI, 6.1~9.8months), the median time for overall survival was 14 months (95% CI, 8.5 ~ 19.5months), 1-year overall survival rate was 55.6% ,6-month progression-free survival rate was 81.8%. there were no severe temozolomide related toxicities. Conclusion: Concurrent temozolomide with radiotherapy and followed by 6 cycles of temozolomide in the treatment of high grade gliomas had better clinical efficacy, the patients tolerated the strategy well and no severe toxicities were observed.

Objective The aim of the current study was to investigate the prognostic value of extracapsular lymph node spread in gastric cancer patients and to find correlations with clinicopathological parameters.Methods Clinicopathological data of 131 gastric cancer patients who underwent gastrectomy with lymphadenectomy were analyzed retrospectively. The number of metastatic lymph nodes with extracapsular spread were determined. Multivariate analysis was performed to find the clinical prognosis affecting extracapsular lymph node involvement. Results Seventy-eight patients (59.5%)had perigastric lymph node metastasis. Fortysix cases were detected extracapsular lymph node involvement. The 5-year cumulative survival rate for patients with extracapsular lymph node spread was 13. 5% , while 32 patients with lymph node metastasis but without extracapsular involvement had a 5-year survival rate of 39.3%. The survival rate decreased significantly with the increase of extracapsular lymph node involvement(P =0.001). Extracapsular lymph node involvement was significantly associated with the higher number of metastatic lymph nodes, the location of lymph node metastasis, tumor invasion depth and distant lymph node metastasis. In the multivariate analysis, extracapsular lymph node spread also remained as an independent prognostic factor(P =0.003). Conclusions Extracapsular lymph node involvement is a convenient and reliable prognostic index, and is an independent prognostic factor in gastric cancer patients. In future staging systems for gastric cancer, extracapsular lymph node involvement should be considered, be pathologically checked and reported in order to determine extracapsular spread status.

Aim To study the protective effects of Rhynchophyll a of total alkaloids ( RTA ) on cerebral ischemia/reperfusion injury and the possi ble mechanism of action. Methods The effects of RTA on decapit ated gasping model and model of middle cerebral artery ischemia 2 h/reperfusion 22 h were observed. The neurological scores, cerebral infarct volume and cerebr al water content after ischemia/reperfusion were observed in rats respectively. The activities of NOS and SOD and the content of MDA in rat's brain tissue were measured. Neuron apoptosis in ischemia penumbral area were detected by terminal depoxynucleotidyl transferase mediated dUTP-biotin nick end labeling ( TUNEL ) . Results The average gasping times in mice treated with RTA 50 , 75 mg?kg -1 was significantly prolonged. The cerebral infarct volume and cerebral water content in rats treated with RTA 40, 60 mg?kg -1 were sign ificantly decreased in ischemic rats. RTA 40, 60 mg?kg -1 increased the ac tivity of SOD ,and decreased the activity of NOS and the content of MDA in the i schemic brains of rats. The number of apoptotic neurons in ischemia penumbral ar ea of cerebral tissue of rats treated with RTA 40, 60 mg?kg -1 was signif icantly lower than that in control rats. Conclusions RTA has pr otective effect on cerebral ischemia/reperfusion injury; this may be related to inhibit the activity of NOS and lipoperoxidation, and increasing the activity of SOD and decreasing neuron apoptosis.
