Chinese Journal of Biochemical Pharmaceutics 2014;(2):86-89
Objective To investigate the clinical efifcacy of Tiotropium Bromide inhaler on patients with stable chronic obstructive pulmonary disease(COPD). Methods 134 cases with stable COPD were equally randomized into three groups. The conventional treatment group(n=46) were 40 male and 6 femal, aged (63.20±9.3)years old and treated with sustained-release theophylline 0.1 g orally. Observation group with 18μg Tiotropium Bromide(n=45) were 40 male and 5 femal, aged (63.4±85)years old, and given inhaled Tiotropium Bromide 18μg. Observation group with 32μg Tiotropium Bromide(n=43) were 39 male and 4 femal, aged (63.2±9.0)years old, and given inhaled Tiotropium Bromide 32 μg. All patients received same routine therapy, and lasted for 4 weeks. improvement Pre-and post-treatment Lung function and quality of life were compared among those groups. Results In observation group, the results of St George respiratory questionnaire decreased signiifcantly after treatment, which was signiifcantly lower than those of the routine-treatment group (P<0.05). FEV 1/FVC, FEV 1/Pred, FEV 1 were signiifcantly higher than those before treatment (P<0.05). However, the control group showed no signiifcant difference. Conclusion Inhaled Tiotropium Bromide can improve lung function and life quality of paitents with stable COPD, the dose with 32μg per day, which was signiifcantly lower than 18μg per day.

Objective To retrospectively analyze the data of patients with T3N0-1M0 nasopharyngeal carcinoma (NPC) who underwent radiotherapy (RT) alone or concurrent chemoradiotherapy (CCRT), and to investigate the relationship between therapeutic modality and prognosis. Methods From January 2004 to December 2004, 781 patients with biopsy-proven newly diagnosed non-metastatic NPC were analyzed in Sun Yat-Sen University Cancer Center, who had MRI data of nasopharynx and neck. With restaged based on the Chinese 2008 staging system, 82 cases of T3N0-1M0 patients who were treated by RT alone or CCRT were enrolled. They were divided into group A (46 cases, RT) and group B (36 cases, CCRT). Results The clinical data was comparable between the two groups. The 5-year overall survival rate (OS) was 93.5 % (group A) and 100 % (group B)(P =0.046), while the 5-year disease-free survival rate (DFS) was 85.2 % (group A) and 91.7 % (group B) (P =0.498). N-Staging was the factor affecting the DFS. Stratified analysis showed that the 5-year OS of T3N0M0 patients was 94.7 % (group A) and 100 % (group B) (P =0.432), those of T3N1M0 patients were 92.6 %(group A) and 100 %(group B) (P =0.066), while the 5-year DFS was 73.7 % (group A) and 89.3 % (group B) (P =0.244). Multifactor analysis showed that CCRT was not the independent factor affecting the OS(HR =0.019; 95 % CI, 0 to 21.793), and N-stage was not the independent factor affecting the DFS (HR = 0.203; 95 % CI, 0.135 to 1.231×104). Conclusion For T3N0M0, NPC patients, CCRT is not superior to RT alone. Whether CCRT can improve survival of T3N1M0 NPC patients needs further study.

Objective To assess the efficacy and feasibility of neoadjuvant therapy of TPF regimen including docetaxel (TAX), cisplatin (DDP) and 5-fluorouracil (5-Fu) combined with concurrent DDP and radiotherapy (RT) in patients with local advanced nasopharyngeal carcinoma (NPC). Methods From April 2008 to May 2009, 40 patients with newly diagnosed UICC stage Ⅲ orⅣ local advanced NPC were enrolled. Patients were randomly assigned to group A(DDP every 3 weeks) and group B(DDP every week). Two cycles of induction chemotherapy with TAX 60 mg/m2 dl, DDP 60 mg/m3 dl and 5-Fu 600 mg/m2 dl-5 were given on a 3-weekly cycle, followed by RT and chemotherapy(group A: DDP 80 mg/m2 every 3 weeks for 2 times; group B: DDP 30 mg/m2 weekly for 6 times). Two-dimension conformal RT technique with 68-72 Gy/(34-36) fractions for 7 weeks was administered to the nasopharynx and 60-66 Gy/(30-33) fractions for 6-6.5 weeks to the node-positive area. Results 38 patients (78 Cycles) were evaluable for efficacy and toxicity. One patient in each group was excluded due to toxicity. 17 (17/19) patients of group A finished 2 cycles of planed DDP chemotherapy, while only 10 (10/19) patients of group B completed 6 weeks of planed DDP chemotherapy, 4 completed 5 weeks, 4 completed 4 weeks and 1 completed 2 weeks. Response to neoadjuvant TPF was as follows: 4 patients (10.5 %) achieved complete response(CR), 27(71.1%) achieved partial response(PR) and 7 (18.4 %) achieved stable disease (SD), so the overall response (CR+PR) rate was 81.6 %. After RT, 32 patients (84.2 %) achieved CR, 5 (13.2 %) PR and 1 (2.6 %) SD, so the overall response rate was 97.4 %. Conclusion TPF induction chemotherapy followed by concurrent DDP and RT is an effective regimen in the treatment of advanced NPC. Concurrent DDP chemotherapy on a 3-weekly cycle is recommended. Further study should be made to investigate how to increase the dose intensity of chemotherapy.
