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.

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.

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.

Transient receptor potential vanilloid 1 (TRPV1) is a non-selective positive ion channel that is mainly expressed in sensory neurons and a member of transient receptor potential (TRP) family. The receptor could be activated by mechanical irritation, chemical irritation or endogenous ligand to mediate pains and cause injury to body functions. Traditional Chinese medicine believes that the mechanism of pain is that "stagnation leads to pain". Specifically, both of the contracture and tautness caused by cold and the blood stasis could result in blood impassability and pain. Most of traditional Chinese medicines for clearing heat and removing toxicity have the anti-inflammatory effect, while those for warming interior, and promoting blood circulation to remove blood stasis have the effect in smoothening blood vessels. Therefore, either with the anti-inflammatory effect or the effect in smoothening blood vessels, traditional Chinese medicines for clearing heat and removing toxicity, warming interior, and promoting blood circulation have the analgesic effect In this paper, the authors summarize the analgesic effect of the above three traditional Chinese medicines, with TRPV1 as the target.

Objective To investigate the career decision-making self-efficacy as well as the psychological well-being of medical students and to discuss the correlation between them.Methods A cross-sectional survey with cluster random sampling was performed anonymously among 714 students of different majors and different grades in an medical University.The contents of the survey included the career decision making self-efficacy scale (CDMSE) as well as the self-reporting inventory(SCL-90).All data in the two groups were analyzed with t test; comparison of data between groups were analyzed with One-Way ANOVA; multiple comparison was analyzed with S-N-K; Pearson and Partial correlation analysis were used to analyzed the correlation between the career decision making self-efficacy and wellbeing.Results Totally 659 students completed the inventory,with response rate being92.3％.Average score of the participants' career decision-making self-efficacy was (124.72 ± 26.76)points,situating at the middle and lower level.There were differences in the scores of career decision making selfefficacy among different sexes,sources,grades and being student cadres or not (P =0.019,0.000,0.027,0.026) ; No differences was found among students of different majors and whether being the only child(P =0.243,0.223).Results of the SCL-90 inventory demonstrated that medical students had some psychological problems including obsessive-compulsive,interpersonal sensitivity and anxiety.Correlation analysis showed that psychological well-being and career decision-making self-efficacy was negatively correlated.Conclusions Measures should be taken to improve the medical students' career decision-making self-efficacy according to their psychological characteristics and to improve the medical students' psychological status by the improvement of career decision-making self-efficacy.

Objective To study the effect of mixed purified autogenic and allogeneic hematopoietic stem cell transplantation for the treatment of systemic lupus erythematosus. Methods Thirty-six MRL/lpr mice were randomly divided into the control group, the study group,the mixed group ( the ratio of autogenic to hematopoietic stem cells, mixed in different proportions were infused intravenously after 60Co irradiation. The study group were treated with daily intraperitoneal infusion of dexamethasone 1 mg·kg-1·d-1, while the control group were treated with intraperitoneal infusion of equivalent volume of saline daily. The changes of serum creatinine level, the urine protein excretion of the mice and blood WBC count were compared. Repeat measures ANOVA was used for data analysis. ELISA was used for anti-nuclear antibody detection Light microscopy, electronic micros-copy, immunofluorescence were applied to detect the pathological changes in renal tissue. Results Serum creatinine and urine protein excretion levels increased with time in the ontrol group, while those of the transplant group and the study group decreased. The reduction in mixed transplantation group and the study group was more evident compared with that of the allogeneic group. The difference was statistically significant (P＜0.05), but there was no significant difference between the mixed transplantation groups and the study group (P＞0.05). The histopathologic damage was most serious in the control group as pathological injury score of most mice were in grade 3 or 4. The majority of the histopathologic damage of the allogeneic group was in grade 2. Most f pathological damage of the study drug group and the mixed transplantation group were grade 1 or 2. Conclusion Mixed hematoopoietic stem cell transplantation for the treatment of murine systemic lupus erythematosus can effectively correct heavy proteinuria in murine systemic lupus erythematosus so improve the renal damage. It is a safe and effectively way to treat murine systemic lupus erythematosus.

AIM: To investigate the efficacy of N-acetylcysteine (NAC) and taurine (Tau) in preventing hyperoxia-induced the lens opacification and the changes of biochemical parameters on organ cultured rabbit lenses.METHODS: Twenty-four lenses from adult rabbits were divided into the control group, the hyperoxia-exposed group, the hyperoxia-exposed group containing 20mmol/L of NAC, the hyperoxia-exposed group containing 80mmol/L of Tau, respectively. The treated groups incubated with hyperoxia ( pO2>80%) for 4 hours per day throughout a 7-day period. Lens transparency, histology and enzymatic activities measurements were determined after this incubation.RESULTS: Gross morphological examination of these lenses revealed some severe cortical opacification in the hyperoxia-exposed group, moderate cortical opacification in the control group and the Tau treated group. There was minimal cortical opacification in the NAC treated group. The glutathione (GSH) content and the activity of Na, K-ATPase were significantly decreased in the hyperoxia-exposed group than that of the control group, by 37.8% (P<0.05) and 53.5% (P<0.05), respectively. However, they were increased in the two treated groups, especially in the NAC treated group. There were no significant differences in the water-soluble protein content and the catalase and GSH reductase activities in all group lenses.CONCLUSION: Hyperoxia can induce the cortical opaci-fication in the lens. The role of NAC in the prevention of hyperoxia-induced cataract is superior to Tau.
