Effects of centralized volume-based procurement policy on the use of drugs for non-small cell lung cancer in a third-grade class-A cancer hospital / 中国药房

OBJECTIVE To analyze the effects of centralized volume-based procurement policy （hereinafter referred to as “centralized procurement”） on the use of anti-tumor drugs in medical institutions. METHODS The interrupted time series model was used to analyze the changes in the monthly purchase volume and purchase amount of docetaxel， gemcitabine and pemetrexed disodium in a third-grade class-A cancer hospital in Shanxi province from January 2018 to December 2021. RESULTS & CONCLUSIONS After the implementation of the centralized procurement policy， both the selected drugs and the non-selected drugs had different degrees of price reduction， and the price reduction of the selected drugs was far greater than that of the non- selected drugs； average monthly purchase volume and amount of docetaxel decreased significantly in that month after the implementation of the policy， while those of gemcitabine and pemetrexed disodium increased significantly （P＜0.05 or P＜0.01）. After the implementation of the policy， the average monthly purchase volume and amount of gemcitabine showed a downward trend， while those of docetaxel and pemetrexed disodium showed an upward trend （P＜0.05 or P＜0.01）. It is suggested that hospitals should strengthen pharmaceutical administration， and avoid adopting a “one size fits all” approach to non-selected drugs； relevant departments should further expand the collection range of anti-tumor drugs or carry out special collection of anti-tumor drugs， so as to save medical insurance funds and reduce medical expenses.

Role of liver sinusoidal endothelial cells in the pathogenesis of nonalcoholic fatty liver disease / 临床肝胆病杂志

With the increasing incidence rate of nonalcoholic fatty liver disease (NAFLD) in Western developed countries and rich regions of China year by year, the treatment methods for NAFLD have been constantly improved and NAFLD has become a research hotspot. As an important physiological structure of the liver, liver sinus endothelial cells (LSECs) play an important role in the development and progression of NAFLD. This article summarizes the mechanism of action of LSECs in the pathogenesis of NAFLD, which included the following aspects: LSEC capillarization occurs in nonalcoholic fatty liver and promotes steatosis; meanwhile, LSECs contribute to oxidative stress in nonalcoholic steatohepatitis (NASH) and is a major effector of liver inflammation in NASH, thus promoting liver fibrosis; in addition, angiogenesis is highly stimulated and promotes NAFLD-related hepatocellular carcinoma in NAFLD. However, the role of LSECs in NASH-associated liver cirrhosis has not been validated, which needs to be further clarified to provide new ideas and directions for treatment.
