Objective To explore the clinical application value of blood routine examination in judgment of the activity of inflammatory bowel diseases.Methods 102 patients with inflammatory bowel disease were selected as the main research objects,60 healthy persons in the same period were selected as the control group,all of the subjects were received routine testing of blood,C-reactive protein and erythrocyte sedimentation rate,and the relationships between disease and blood routine indexes were compared.Results In UC group,the PLT,WBC RDW index levels of remission were higher than those of the control group,the differences were statistically significant(t =6.75,8.21,5.73,all P ＜0.05).In patients with UC,the HGB,HCTand MPV index levels were lower than those in the remission patients and the control group,the differences were statistically significant(t =8.12,11.03,6.72,9.35,10.23,8.71,all P ＜0.05).But the PLT index was higher than that of patients in remission,the RDW and WBC indexes were higher than those in the control group and the remission period,there were statistically significant differences (t =7.59,8.51,6.03,all P ＜ 0.05).The routine blood indexes of the relief patients of CD group had significant differences compared with the control group(t =6.17,7.29,9.01,10.35,8.27,7.69,8.01,9.91,allP ＜ 0.05),the HCT,MCV,HGB and MPV indexes were lower than those of the control group,the differences were statistically significant (t =9.01,10.35,8.27,9.9i,all P ＜ 0.05),the WBC,PLT,N and RDW indexes were higher than those of the control group,the differences were statistically significant (t =6.17,7.29,7.69,8.01,all P ＜ 0.05).In UC group,the HGB,HCT,MCV and MPV indexes were lower than those in the remission patients and the control group,there were statistically significant differences(t =8.19,6.97,7.53,9.02,all P ＜ 0.05).But the PLT,RDW,WBC and N indexes were higher than those in the remission patients and the control group,the differences were statistically significant (t =9.81,7.94,8.36,7.61,P ＜ 0.05).In the active patients of CD group,the WBC and N indexes were significantly higher than those of UC group,the differences were statistically significant (t =8.15,9.07,all P ＜ 0.05).In the remission patients of CD group,the PLT index was significandy higher than that in the remission patients of UC group,the difference was statistically significant (t =10.35,P ＜ 0.05).Conclusion Indexes of blood routine has obvious significance in activity of inflammatory bowel disease,and it is significant correlation with inflammation index,which can be used as one of the routine clinical method to determine the activity of inflammatory bowel diseases.

Objective To analyze the status of quality of life (QOL) and the related factors in pa-tients with uasopharyngeal carcinoma (NPC) after radiotherapy, and to explore the significance of intensity modulated radiotherapy (IMRT) in decreasing side effects and improving QOL. Methods A questionnaire including 35 items was designed according to EORTC QLQ-30 and the related symptoms and side effects of NPC. 142 NPC patients surviving with disease-free after radiotherapy were surveyed for the evaluation of QOL. The median follow-up was 25 months. The information of social demography and clinical details were collected. The patients were divided into IMRT group (75 patients) and conventional radiotherapy (CRT) group (67 patients). A statistical software package SAS 8.1 was used to compare the marks of QOL between the groups and analyze the influencing factors. Results In IMRT group and CRT group, the marks of affec-tire cognitive domain were 82.8±14.7 and 77.5±16.0(t=2.07, P=0.040);and the marks of disease and treatment-related symptoms, and reactive domain were 78.9±10.3 and 69.8±13.3 (t=4.59, P=0.000). The marks were significantly different in xerostomia, trismus, deglutitory choke, hoarseness, re-striction of neck movement and dysphagia (P < 0.05). Of the influencing factors of QOL, the domain of body function was sex (regression coefficient was -4.692), the self-evaluation of total QOL were follow-up time and educational background (regression coefficients were -0.618 and 12.316, respectively), the fi-nancial status was family monthly income per capita (regression coefficient was -11.133), and the disease and treatment-related symptoms and reactive domain were group (techniques of radiation) and age (regression coefficients were -9.384 and -5.853, respectively). Conclusions IMRT could improve the QOL through decreasing the side effects of patients with NPC including xerostomia, trismus, restriction of neck movement and dysphagia. Sex, age, family monthly income per capita, educational background, fol-low-up time and the irradiation techniques may affect QOL.
