Objective To analyze the index of relative apparent diffusion coefficient (rADC)of magnetic resonance diffusion weighted imaging (DWI)for nasopharyngeal carcinoma with cervical metastatic lymph node before and after treatment,assess the application value of rADC in the recent curative effect after radiotherapy and chemotherapy.Methods 45 cases of nasopharyngeal carcinoma with cervical metastatic lymph nodes proved pathologically were selected as the research objects,which was including 107 pieces of metastatic lymph nodes and underwent DWI.The rADC index of cervical metastatic lymph nodes before and after radiotherapy and chemotherapy was measured and calculated.The cervical metastatic lymph nodes were divided into effective group (CR+PR,n=84)and ineffective group(SD+PD,n=23),and the difference of the rADC index between the two groups was compared.Results For the target volume disappeared or reduced more than 30% in the effective group after treatment,the rADC index was significantly higher than that before treatment(t=4.981, P<0.05).The rADC difference between effective group and ineffective group was statistically significance (t=3.471,P<0.05).Conclusion rADC can be used as the auxiliary marker for the evaluation of short-term curative effect of nasopharyngeal carcinoma with cervical metastatic lymph nodes.

Objective To explore the effect of the single maximum of alcohol consumption on vomiting induced by chemotherapy in male patients with nasopharyngeal carcinoma.Methods According to the single maximum of alcohol consumption,48 cases of male patients with nasopharyngeal carcinoma were divided into two groups:group A (small capacity for liquor group 10-50 g),group B (large capacity for liquor group >50 g).The amount of alcohol intake was assessed by a questionnaire.The responses of vomiting and the effects of antiemetic therapy between the two groups during the first cycle after induction chemotherapy were observed.Results The incidence rates of vomiting induced by chemotherapy between the two groups were 52.0% and 17.4%,respectively.There were significant differences between the two groups (x2 =6.273,P <0.05).The incidence rates of grade 0,1,2 and 3 of vomiting in group A were 48.0%,20.0%,20.0%,12.0%,in group B were 82.6%,13.0%,4.4%,O,respectively.There were significant differences between the two groups (x2 =6.013,P =0.024).In the two groups,the complete control rate for acute vomit were 48.0% and 82.6% (x2 =6.273,P =0.012),for delayed vomit were 36.0% and 65.2% (x2 =4.090,P =0.043).There were also significant differences between the two groups.Conclusion With the increasing of capacity for liquor,the incidence of vomiting is significantly reduced,the degree of vomiting is distinctly alleviated,and the antiemetic efficacy is distinctly increased.
