ABSTRACT
OBJECTIVE:To observe the clinical efficacy and safety of Aidi injection combined with TP regimen in the treat-ment of non-small cell lung cancer. METHODS:62 patients with non-small cell lung cancer were randomly divided into control group and observation group,31 cases in each group. Control group received TP regimen alone,observation group additionally re-ceived 40 ml Aidi injection,dissolved in 500 ml 0.9% Sodium chloride injection by intravenous infusion. 21 d was a treatment course,and it lasted 4 courses. The level of inflammatory cytokines before and after treatment and post-treatment quality of life, short-term efficacy,patients’satisfaction and toxicity reactions in 2 groups were compared. RESULTS:After treatment,the level of inflammatory cytokines in 2 groups were significantly lower than before,and observation group was lower than control group, the differences were statistically significant (P<0.05). The effective rate of life quality (80.64%) and short-term efficacy (83.87%)in observation group significant were higher than control group(32.25%,64.52%,respectively),the differences were statistically significant (P<0.05). Satisfaction degree (96.77%) in observation group was significantly higher than control group (77.42%);and the incidences of thrombocytopenia,leukopenia,abnormal liver function were significantly lower than control group,the differences were statistically significant (P<0.05). CONCLUSIONS:Aidi injection combined with TP regimen shows good efficacy and little toxicity in the treatment of non-small cell lung cancer,and it helps to reduce the level of inflammatory cyto-kines in patients,improving immune function and the quality of life of patients.
ABSTRACT
Silver nanoparticles ( AgNP) , the metallic silver par-ticles with the diameter of 1 ~100 nm are now widely used in many fields. Many researches show that the smaller size of Ag-NP, the stronger toxicity it shows. Generally speaking, AgNP with 20 nm shows strongest toxicity. After entering the body, they are distributed in different organs in the body, and the dis-tribution in the kidney shows a certain gender difference. They also produce some toxic effects after entering body organs. AgNP often exhibit dose effect on the toxicity in vitro cells,while in vivo experiments, their toxic effects change with the different objects and ways of acting. In addition, AgNP can produce toxic effects on reproduction, and may cause parental reproductive activity to deteriorate, and pass the toxic effects to offspring through the placenta to exert a negative influence on the growth and develop-ment of the offspring. The toxicity mechanisms of AgNP are oxi-dative stress injury caused by producing free radicals;metabolic disorders caused by reducing of drug metabolic enzyme activity;and also related gene expression defects and certain molecules, such as transcription factor NF-E2-related factor 2(Nrf2) prote-ase caused by abnormal expression. In short, AgNP can be toxic to organisms, and we must evaluate their biological safety when we use it, to minimize or even avoid the danger it brings about.
