The significance of the study on the human healht effects of inhalable particulates(PM10) was pointed out,specific properties of inhalable particulates,such as chemical components,aerodynamic behavior and transference in respiratory tract,were then presented.The serious harm of inhalable particulates on human health were summarized based on research results of epidemiological study,animal toxicological study and clinical study,and research emphasis to which should pay more attention in the future study of this aspects was also suggested.

The adhesion in the gallbladder triangle is the most important factor influencing the conversion to laparotomy in laparoscopic cholecystectomy (LC).The degree of adhesion in the cholecystic triangle is closely related to the difficulty of LC operation.With the reduction of cholecystic triangle adhesion,the treatment of gallbladder during LC will be easy and the rate of conversion to laparotomy will decrease accordingly.In order to investigate the causes of cholecystic triangle adhesion and its influence on LC,this paper reviews the current research progress.
