Diagnosis-Related Groups payment reform and hospital cost control.

Background: This study explores the influence of Diagnosis-Related Groups (DRG) payment reform on hospital cost control and offers pertinent cost management strategies for public hospitals. It situates the research by elucidating the significance of the DRG payment method and comparing its advantages and drawbacks with the traditional 'pay per project' model.

Objective: The primary aim is to assess the impact of DRG payment reform on hospital cost control and propose effective cost management strategies for public hospitals.

Interaction Between Environmental Risk Factors and Catechol-O-Methyltransferase (COMT) and X-Ray Repair Cross-Complementing Protein 1 (XRCC1) Gene Polymorphisms in Risk of Lung Cancer Among Non-Smoking Chinese Women: A Case-Control Study.

BACKGROUND Various studies have highlighted the link between polymorphisms in the XRCC1 gene (encoding X-ray repair cross-complementing group 1) with the incidence of decreased DNA repair capacity and an increased predisposition to cancer. Catechol-O-methyltransferase (COMT) plays a crucial role in estrogen-induced cancers. In the present study was analyzed the potential influence of XRCC1 and COMT gene polymorphisms as predisposing factors from a lung cancer perspective, in addition to conducting an investigation into their interaction with environmental risk factors in relation to lung cancer among non-smoking Chinese women.

[Effect of simvastatin on bone morphogenetic protein-2 expression in the periodontal tissue after rat tooth movement].

Objective: To investigate the effect of systematic administration of simvastatin on the bone morphogenetic protein-2 (BMP-2) expression in the periodontal tissue after rat tooth movement and on the relapse of tooth movement.

Methods: Orthodontic tooth movement of upper first molar was performed in 32 rats with coil spring for 21 days. The 32 rats were randomly allocated into 4 groups: negative control group (isotonic saline) and three experimental groups (2.
