Objective:To study the clinical characteristics of malignant lymphomas of the head and neck.Methods:The clinical data of 139 patients with malignant lymphomas of the head and neck were retrogradely analyzed,and the long term follow up was carried out.Results:Among all the cases there were 128 non Hodgkin's lymphoma(NHL) and 11 Hodgkin's disease(HD). The average ages of patients with HD and NHL were 41.8 and 50.0 years old respectively.There were lymphadenopathy in all patients with HD and 72.7% of those with NHL. Extranodal involvement occurred in 27.3% HD patients and 75.8% NHL patients; general symptoms appeared in 45.5% HD patients and 37.5% NHL patients. Most patients received chemotherapy of CHOP and improved CHOP scheme.The average follow up time was 23.4 months. Twelve patients died and the 3 year survival rate was 55.6%.Conclusion:In our group, the patients present an older age and NHL is more common than HD.The cases with cervical lymphadenopathy are easy to be diagnosed,and the clinical stage classification is useful for the prognosis.

Objective To study the clinical effect of parecoxib sodium for injection combined with psychological intervention on postoperative analgesia in the patients with thyroid cancer. Methods 100 patients with thyroid cancer Hangzhou tumor hospitalfrom July 2015 to April 2017 were randomly divided into two groups, the experimental group and the control group. The control group were given parecoxib sodium for injection, and the experimental group were received parecoxib sodium for injection combined with psychological intervention. Three days after treatment, the average amount of parecoxib sodium for injection and SAS, SDS score in the two groups were compared. Results The average dosage of parecoxib sodium for injection in the experimental group was (45.6±9.7) mg, and (67.9±9.5) mg in the control group. In the control group, SAS was (45.88± 7.56)points before treatment and (50.42±7.91) points after treatment, SAS was (45.94±7.32)points before treatment and (40.81 ± 6.61) points after treatment. SDS in the control group before treatment was (45.53±8.62) points and (50.29±7.24) points after treatment. In the experimental group, SDS before treatment was (45.41±7.18) points and (40.36±6.15) after treatment. The differences of all the data were statistically significant in the two gorups(P<0.01). Conclusion Postoperative psychological intervention can effectively enhance the analgesic effect of parecoxib sodium for injection, reduce the dosage and also improve the psychological score. This treatment is worthy of clinical promotion.
