Silicosis is a diffuse pulmonary fibrosis disease caused by occupational exposure to silica, which is one of the occupational diseases with high incidence in developing countries. Up to now, there is no definite drug to relieve or reverse the lung injury caused by silicosis, so it is very important to prevent, diagnose and treat pulmonary fibrosis as soon as possible. Studies have shown that a chronic inflammatory environment contributes to pulmonary fibrosis to a certain extent. Interleukin-1β is a cytokine that increases the number of inflammatory factors in the microenvironment in the immune response and plays a key role in inflammatory reaction. Therefore, the release of interleukin-1β is of great significance in the pathogenesis of silicosis. This paper aims to systematically expound the development course of silicosis, the signal pathway of interleukin-1β production, and the relationship between them.

OBJECTIVE To ex plore the economic value of medication therapeutical management （MTM）service for patients with stable coronary disease. METHODS Totally 140 patients with stable coronary disease were divided into a control group and a intervention group ，70 cases in each group. Patients in control group were received routine medical services ，and patients in intervention group additionally received standardized MTM services on this basis. Medication complication ，satisfaction degree ， safety indexes and efficacy indexes were compared between 2 groups. From the perspective of the whole society ，the economic value of MTM service for patients with stable coronary disease were evaluated by pharmacists using cost minimization analysis. RESULTS A total of 15 patients did not complete the study ，including 5 cases in intervention group and 10 cases in control group ； there was no death endpoint during the follow-up period. MMAS- 8 score，satisfaction score of drug communication dimension and score of overall satisfactionin of intervention group were obviously higher than control group （P＜0.01）. There was no significant difference in blood pressure standard rate ，blood lipid standard rate ，the incidence of adverse drug reaction ，and the incidence of acute coronary events between 2 groups（P＞0.05）. The total cost of intervention group was lower than that of control group （P＜ 0.01）；the results of sensitivity analysis were consistent with those of cost minimization analysis. CONCLUSIONS Pharmacists implement MTM service for patients with stable coronary disease can reduce total cost ，save medical resources and has economic advantages.
