All organisms regulate their life activities through the biological clock, which makes a variety of activities regular.For example, many physiological activities such as sleep-wake cycle, temperature, heart rate, blood pressure, endocrine and metabolic activity of the kidney and liver are subject to the regulation of circadian rhythms, that is to say they are all under the control of circadian pacemaker.Physiological activity of cell cultured in vitro also possess rhythms.This paper conducts a brief overview of biological clock of cell cultured in vitro and analyzes the molecular mechanism of the biological clock of the neurons and peripheral tissue cell as well as the existing problems, which provide reference for comprehensive interpretation of the molecular mechanism of biological clock.

Objective　To study the alterations of surfactant protein A (SP-A) and B (SP-B) in rats in the early stage of acute lung injury induced by oleic acid. Methods　An acute lung injury model was established by injecting oleic acid into the superior vena cava of rats and the levels of SP-A and SP-B in branchoalveolar lavage fluid (BALF) were determined with Western Blot and ELISA. Results　The levels of SP-A and SP-B in BALF were significantly decreased in the injured group 1 h after acute lung injury (P<0.01) and remained low in the next 6 h. Conclusion　The levels of SP-A and SP-B were decreased in the early stage of acute lung injury. The methods used for detecting SP-A and SP-B we adopted are specific and sensitive, and might be helpful for other experimental study.

OBJECTIVE: To study the chemical constituents of Scirpus yagara Ohwi. METHODS: Column chromatography techniques were applied to isolate the constituents. The chemical structures of the constituents were elucidated on the basis of physicochemical properties and spectral data. RESULTS: Forteen compounds were isolated and identified as sanleng diphenyllactone (1), β-sitosterol (2), ferulic acid(3), succinic acid(4), azelaic acid(5), docosanoic acid (6), 6, 7, 10-trihydroxy-8-octadecenoic acid(7), 4, 4-dime-thyl-1, 7-pimelic acid(8), vanillic acid(9), 3, 5-dihydroxy-4-methoxy-benzoic acid(10), p-hydroxybenzaldehyde(II), 3, 4-dihydroxy-benzoic acid(12), 2, 7-dihydroxy xanthone(13) and daucosterol(14). CONCLUSION: Compounds 1-10 and 12-14 are obtained from this plant for the first time, and compounds 1 and 13 were obtained from the genus Scirpus for the first time.

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.

Professor GAO Yuchun is considered as the key successor of GAO's academic school of acupuncture and moxibustion in Yanzhao region. Professor GAO's clinical experience of, "sequential acupuncture" is introduced in details in this article. In Professor GAO's opinions, appropriate acupuncture sequence is the key to satisfactory clinical effects during treatment. Based on different acupoints, sequential acupuncture can achieve the aim of qi following needles and needles leading qi; based on different symptoms, sequential acupuncture can regulate qi movement; based on different body positions, sequential acupuncture can harmonize qi-blood and reinforcing deficiency and reducing excess. In all, according to the differences of disease condition and constitution, based on the accurate acupoint selection and appropriate manipulation, it is essential to capture the nature of diseases and make the order of acupuncture, which can achieve the aim of regulating qi movement and reinforcing deficiency and reducing excess.
