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.

Objective To study the influence of exposure factors on posttraumatic stress disorder( PTSD) and Posttraumatic Growth( PTG) in middle school students in disaster area four years after the Wenchuan earth?quake . Methods 1 526 students from four schools in Worst?Hit Areas were investigated with Self?compiled Earth?quake Exposure Factors Questionnaire,Posttraumatic Growth Inventory( C?PTGI) and Impact of Event Scale( IES?R). Data were analyzed by ANOVA and multiple linear regression analysis.Results The score of IES?R had sig?nificant difference between different levels of all exposure factors(F=5.75~89.10, P<0.05) ,and students with high exposure level((26.68±14.66),(26.80±15.56),(27.83±14.62),(29.02±15.36),(27.77±15.74),(26.74± 15.63),(25.43±14.32),(29.51±14.36)) had heavier symptoms of PTSD than those with low exposure level ((22.84±13.96),(23.98±13.99),(23.63±14.21),(23.53±13.96),(23.64±13.83),(24.24±14.15),(21.27± 14.35),(17.54±13.34)). Only exposure factors of having witnessed someone injured and having close friends se?riously injured or being killed could significantly influence the score of PTGI(F=11.82, P=0.001;F=6.23, P=0.013). Regression analysis showed that five exposure factors (grade,having felt scared,having family members being killed,having close friends seriously injured or being killed,having witnessed someone injured) had signifi?cant effect on IES(ΔR 2=0.141) ,but only one factor( having witnessed someone injured) had weak effect on PTG (ΔR 2=0.007).Conclusion Exposure factors can predict posttraumatic stress symptoms in middle school students in Wenchuan four years after the earthquake,and the emotion of fear is a strongest predictor,but they can not pre?dict posttraumatic growth.

Objective:To investigate the protective effects of Panax notoginseng on myocardial ischemia injury in dogs and study the spectrum-activity relationship of Panax notoginseng. Methods:Firstly, the HPLC fingerprint analytical method for Panax notogin-seng was established, and then the dog model of acute myocardial ischemia was established by left anterior descending coronary liga-tion. Bivariate correlation analysis and multivariate regression analysis were used to correlate the spectrum-activity relationship between the fingerprints and the anti-myocardial ischaemia activity, and the spectrum-activity relationship and efficacy material foundation of Panax notoginseng were determined. Results:The main effective components were Ginseng saponin Rg1 and Rb1 and notoginseng sapo-nins R1 etc. Notoginseng saponins R1 could significantly inhibit the increase of serum lactate, and ginseng saponin Rg1 could inhibit the increase of FFA in serum, which was the main component in Panax notoginseng for the treatment of myocardial ischemia. Conclusion:The effective substances in Panax notoginseng are obtained by investigating the relationship between the spectrum and efficiency, and a new method for the evaluation of spectrum-activity relationship for Panax notoginseng is established. It can objectively reflect the inher-ent quality of the drug and provide a new strategy for the further research of traditional Chinese medicines.

Objective To explore the effect of different diary method on daily affect of college students.Methods 75 numbers of under-graduates were randomly assigned into information recording group,feeling recording group and control group.Beck Depression Inventory (BDI) and Positive And Negative Affect Scale (PANAS) were used before and after two months intervention.Results For positive emotion,ANOVA results showed no significant (P＞0.05) main effect of time,a significant (P＜0.05) main effect of group(2.76±0.41,2.97±0.50,3.24±0.45),and the time × group had a significant interaction (P＜0.05).Simple effect analysis showed that after the intervention,the positive emotions of information recording group (2.47 ± 0.62) and feeling recording group (2.86±0.64) was lower than the positive emotions of control group(3.35±0.46) significantly(P＜0.05).For negative emotions,there was no significant difference (P＞0.05) in main effects of time,group and interaction;for depression,the main effect of the level of time (8.02± 5.65,5.38 ± 5.04,5.20± 5.51) was significant (P＜ 0.01),and main effect of group and the interaction were not significant(P＞0.05).Conclusion Different diary methods have different effects on the subject's daily affect.

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.
