Objective To explore the short- term efficacy of argon- helium knife cryotherapy followed by chemotherapy in treating advanced non- small cell lung cancer (NSCLC) and to investigate its effect on the long- term survival. Methods During the period from March 2005 to March 2008, a total of 61 patients withⅢb or Ⅳ stage NSCLC received argon- helium knife cryotherapy followed by chemotherapy (study group), and other 52 patients with Ⅲb or Ⅳ stage NSCLC were treated with chemotherapy only (control group). The clinical data were retrospectively analyzed. The pain was evaluated by numeric rating scale (NRS) and the quality of life (QOL) was assessed by functional assessment of cancer therapy- general (FACT- G) scale. The clinical effect was evaluated according to RECIST criteria for solid tumor, and the patient’s survival time was recorded. Results (1) Twenty- six patients had local pain before the treatment, and the pain was relieved in different degrees after cryotherapy. The QOL, including all respects of FACT - G, was significantly improved after cryotherapy in all 61 patients. (2) The remission rate of the study group and the control group was 34.4% and 15.4% respectively, the difference between the two groups was statistically significant (P <0.05). (3) The median survival time of the study group and the control group was 12.9 months and 9.5 months respectively, and the one- year survival rate of the study group and the control group was 53.6% and 35.4% respectively. The differences between the two groups were statistically significant (P < 0.01). Conclusion Argon- helium knife cryotherapy is a safe and effective local treatment for advanced NSCLC, which can quickly reduce the tumor load, relieve the pain and improve patient’s quality of life. Cryotherapy with subsequent chemotherapy is superior to simple chemotherapy in improving the patient’s survival rate.

Objective To investigate thermal degradation kinetic characteristics of Cefmenoxime Hydrochloride in infusion solutions, and predict its thermal stability. Methods The HPLC was applied to determine the contents of Cefmenoxime Hydrochloride. Classical isothermal kinetic method and multivariate linear model were used to predict the expiration date of the injection. Results It was found that the thermal degradation kinetics of Cefmenoxime Hydrochloride in two infusion solutions corresponded with the first-order kinetics. The expiration dates of Cefmenoxime Hydrochloride in 0. 9%sodium chloride injection calculated by two different methods were 2. 20 days and 1. 52 days,and in 5% glucose injection were 2. 09 days and 1. 53 days,respectively. Conclusion The thermal stability of Cefmenoxime Hydrochloride in infusion solutions is poor and its expiration dates are the same calculated by two different methods.
