OBJECTIVE:To optimize the toxicity attenuation processing technology of Amorphophallus sinensis Belval.. METH-ODS:With the overall score of taste stimulation and rabbit eye irritation of A. sinensis Belval. as the index,and based on the sin-gle factor method,orthogonal test was designed to investigate the the influences of the amount of saturated calcium hydroxide solu-tion,heating time and heating temperature on the processing effect,and verification tests as well as irratation comparison before and after processing were conducted. RESULTS:The amount of saturated calcium hydroxide solution and heating temperature had significant influence on the processing effect. The optimal processing technology was to add saturated calcium hydroxide solution 30 times as much as the amount of medicinal materials at 100 ℃ and heat it for 30 min. The verification tests showed overall scores of 8.05,8.44 and 8.37(RSD=2.5%,n=3). The average overall scores before and after processing were 0.12 and 8.54(n=10)re-spectively. CONCLUSIONS:The medicinal materials processed by the optimal technology have lower stimulation and irritation. The optimal technology is stable and reliable.

OBJECTIVE:To provide reference for lung cancer therapy in the filed of TCM and offer guidance for pharmacy work. METHODS:266 lung cancer prescriptions were collected from the department of TCM of our hospital during Jan. to Dec. in 2014,in-vestigated and analyzed in respects of patient’s age,the number of TCM ingredient,the weight and number of dose,cost,drug catego-ries,the frequency of each ingredient use. RESULTS:The high-risk population of lung cancer were over 40 years old group;the num-ber of TCM ingredient were from 16 to 20;the weight of dose was from 200 g to 300 g;the average number of dose was 10.01 with 53.79 yuan in average. Top 3 TCM were tonics (16.5%),TCM for relieving cough,reducing phlegm and preventing asthma (13.5%),TCM for clearing heat(11.5%). Fritillaria thunbergii,Morus alba,Citrus reticulate and Tetrastigma hemsleyanum took up the front place in the list of frequency. CONCLUSIONS:TCM for relieving cough,reducing phlegm and preventing asthma(13.5%) and TCM for clearing heat are frequently used in TCM prescription for lung cancer;all of them are easily damaged by worms,mildew, rot and extensive diffusion of oil. The management should be strengthened.
