Objective To explore the side effects of pemetrexed in the maintenane therapy of nonsmall-cell lung cancer (NSCLC) at advanced stage and summarize the nursing measures. Methods Fifty-one NSCLC patients were treated maintenance therapy by pemetrexed. The side effects were observed and corresponding nursing measures were taken. Results The side effects included bone marrow depression of 33 cases, adverse reactions in gastrointestinal tract of 14 cases, and skin rashes of 4 cases, all at the degree of I-II. All of them were alleviated after active treatments. Conclusion Such nursing measures as close of side effects and careful nursing to the NSCLC patients treated with maintenance therapy with temetrexed are main measures for the success of treatment.

AIM: To investigate the relations between the proliferation and phenotype change of adventitial cells and the expression of T GF-?1 in adventitia after arterial injury. METHODS: After abdominal artery injury in rabbits, adventitial cel l proliferation and phenotype were identified by immunohistochemistry, transmissi on electron microscope and in situ Hybridization. RESULTS: Three days and 7 days after injury, the PCNA-positive ce lls were significantly increased. The previously weakly actin-positive adventiti al cells became strong-actin staining, the typical myofibroblast featurses of ad ventitial cells were detected by TEM 7 and 14 days after injury. Three days afte r vascular injury, there was a marked increase in the nu mber of cells that demonstrated the presence of TGF-?1 transcripts within the adventitia. Seven days after arterial injury, adventitial cells continued to ex press TGF-?1. on day 28, the number of TGF-?1-expressing cells was markedly r e duced in the adventitia. CONCLUSION: This study demonstrates that the proliferation and p henotype modulation of adventitial cells are associated with induction of TGF- ?1 expression in adventitia after arterial injury.
