ABSTRACT
Objective To investigate the effect of matrine on migration, proliferation and apoptosis of hepatic stellate cell (HSC) induced by PDGF in vitro. Methods HSC line was incubated separately with matrine in different concentration of 0.25 and 0.5 mg/ml, cell proliferation was assessed by MTT assay. Apoptosis was tested by TUNEL in situ assay. The migration ability of HSCs was observed with Transwell chamber assay. Results The cell migration rate and absorbance value of the groups with 0.25 mg/ml and 0.5 mg/ml matrine were significantly lower than those of the control group, as well as in PDGF groups. But there was no difference in rates of cell apoptosis among three groups. Conclusion Matrine can inhibit HSC migration, proliferation and induce apoptosis of HSC, which might be one of the mechanisms that matrine counteracts against liver fibrosis. But there was no effect of matrine on HSC apoptosis induced by PDGF.
ABSTRACT
Objective To investigate the frequencies of variant of lipoprotein lipase(LPL)gene,HindIII site at intron 8 and PvuII site at intron 6,and its relation with type 2 diabetes mellitus and insulin resistance(IR).Methods PCR-RFLP method was used to determine the DNA polymorphism of 8 th intron and 6 th intron of LPL gene in 78 T2DM patients and 49 controls.Results(1)Compared with control group,the frequencies of H+H+ genotypes and alleles ″H+″ was significantly higher in type 2 diabetes patients(P
ABSTRACT
With the development of the times and the constant change of the forms of labor, it is imperative to explore the value of labor and principle of distribution of medical workers. The authors first describe a number of relevant concepts, including instruments of labor, forms of labor, value of labor, and human resources. Then they analyze the value of labor of medical workers and their administrators, including the features and forms of the creation of value by medical workers and their administrators. Finally, they expound the importance of deepening reform in the distribution system of medical institutions. By analyzing the theoretical basis for readjusting the distribution mechanism, they put forward the principles of giving expression to the creation of the value of labor in readjusting the distribution system and taking efficiency, capital and production factors into account in distribution and offer suggestions respectively for the reform of the distribution system in profit and non profit medical institutions.
ABSTRACT
The authors give an account of the changes in both internal and external environments that hospitals confront in the new century, emphasizing that it is imperative for hospital managers to manage their hospitals with new concepts and means so as to meet the needs of the times. The paper is focused on 10 ways of management, namely, knowledge management, human resources management, operational management, efficiency and benefit management, new medical quality content management, fuzzy management, information management, image management, humanistic management, and hospital culture management.
ABSTRACT
Firstly the authors expound the management attribute of hospital management ethics, clarifying the connotation of hospital management ethics, the basic issues in the study of hospital management ethics, and the eight functions, tasks and goals of hospital management ethics. Secondly they discuss the relationship between hospital management and hospital management ethics. Thirdly they offer a preliminary account of the application of hospital management ethics in hospital management: ①illustrating via a diagram the application of hospital management ethics in hospital decision-making; ②presenting ways of judging “good” and “evil” activities in the hospital; and ③describing the application of hospital management ethics to the monitoring and assessment of medical programs. Finally they propose some methods for cultivating the capability of the entire staff of the hospital to fulfill the obligations of moral excellence.
