Purpose:To study the effect of amifostine on ef ficacy in patients with advanced non-small-cell lung cancer(NSCLC) treated w ith chemotherapy and the protection of amifostine on myelosuppression induced by chemotherapy and to investigate major adverse reaction induced by amfostine. Methods:33 patients with advanced NSCLC were randomly divided i nto protection group (amosfostine + MMC +VDS + DDP) and control group (MMC + VDS + DDP), The regimen was given every 4 weeks , All enrolled patients were evalua ted for efficacy and hematologic toxicity after 3 cycles of treatment , Patients in both groups were well-matched for baseline disease characteristics. Results:In protection group (PG) , the response rate was 40% (1 CR , 5 PR , 6 NC , 3 PD), whereas in control group (CG) , the response rate was 33.3% (0 CR , 5 CR , 8 NC , 2 PD), the differentce of response rates betwee n two the groups was not statistically significant (P=0.705). The minimum wh ite blood cell (WBC) counts after chemotherapy in treatment group and in control group were (3.387?1.169)?109/L and (2.46?0.98)?109/L respectively (P =0.026). The minimum blood platelet cell (BPC) counts in PG and in CG were (11 4.53?48.24)?109 /L and (88.2?32.83)?109 /L respectively (P=0.091) . The minimum hemoglobin (HB) counts in CG and in CG were (94.4?14.69)g/L and (89 .33?13.98)g/L respectively (P=0.341). Grade (Ⅱ-Ⅳ) leukopenia rate in PG and in CG were 66.7% (10/15) and 33.3% (5/15) respectively (P= 0.068), Gr ade (Ⅱ-Ⅳ) thrombocytopenia rate in PG and in CG were 33.3% (5/15) and 20% (3/ 15) respectively (P= 0.409), Grade (Ⅱ-Ⅳ) hypochromia rate in PG and in CG were 53.3% (8/15) and 46.7% (7/15) respectively (P= 0.715). Major ad verse effects of amifostine were mild hypotension , nausea and vomiting , dizzin ess , malaise etc. Conclusions:Amifostine does not reduce the efficacy of chemothe rapy in patients with advanced NSCLC , it can reduce the hematologic toxicity as sociated with chemotherapy of MVP regimen , the adverse effects of amifostine ar e mild.

Objective To investigate the influence of high-motivated affect background on the holistic face processing and its neural mechanism.Methods Totally 26 subjects were instructed to perform composite-face process under the priming condition of three emotional pictures (food,neutral and fear).Results (1)Behavioral studies showed a significant interaction between emotion type and face combination(F(2,50) =5.37,P=0.008).Composite-face effect was observed in neutral emotional condition due to the fact that the recognition accuracy of the misaligned face ((90.21 ± 11.20)％) was significantly higher than that of the aligned face((84.83 ± 11.20) ％,t (25) =3.95,P=0.001).However,the composite-face effect disappeared under the condition of high-motivated emotion.That is,there was no significant difference in the recognition accuracy of the misaligned faces ((87.88± 10.28)％) and aligned faces ((85.12± 8.81)％,t(25)=1.93,P=0.065) under the condition of high-motivated negative emotion.Under the condition of high-motivated positive emotion,there was also no significant difference in the recognition accuracy between the misaligned faces ((87.92±11.00)％) and aligned faces((88.33±8.89)％,t(z5)=0.263,P=0.795).(2) According to the results of ERP,P3 components showed significant interaction between emotion type and face combination form(F(2,50) =3.23,P=0.048).Under the neutral emotional condition,the P3 amplitude of aligned faces ((3.46 ± 1.26) μV) was significantly higher than that of misaligned faces ((2.82 ± 1.43)μV,F (1,25)=5.28,P=0.03).In the case of high-motivated negative condition,there was no significant difference in P3amplitude between aligned faces ((3.21 ± 1.16) μV) and misaligned faces ((3.07 ± 1.22) μV,F (1,25) =0.53,P=0.476).The P3 amplitude of aligned faces((3.33±1.20) μV) and misaligned faces((3.42±1.40) μV) were also not significantly different under the condition of high-motivated positive affect (F(1,25)=0.23,P=0.638).Conclusion The study shows a high correlation between face processing and emotional processing.Additionally,the emotional motivation has a stronger influence on face processing.Regardless of the emotional valence,high-motivated intensity affect can cause local attention bias and reduce the holistic processing level of the face,which is mainly manifested in the later cognitive processing stage.
