World Health Organization aims to develop safe, effective and practical traditional medicine. Traditional Chinese medicine (TCM) and other complementary and alternative medicine are being recognized in the whole world nowadays. However, the definite effect of Chinese medicine is still in need of scientific research proof. Placebo control is of equal importance to active control and blank control in clinical trial of TCM. This article briefly reviewed the importance of placebo control and commented on its present situation in clinical trial of TCM. This article also brought up the preliminary proposals of placebo application in TCM clinical trial. We should emphasize scientific placebo preparation and good design of placebo-controlled trial, which are directed by International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use. A good clinical trial project will avoid unnecessary wastes and provide safe and effective treatment for people.

This article discusses the variation process of the sense of justice in western and traditional Chinese society,and its effect on regulatory ethics.Western regulatory ethics takes "making use of evil to restrain evil" as its regulatory principle,whose purpose is "to increase goodness by evil",while Chinese regulatory ethics employs "taking goodness in restraining evil" as its regulatory principle.The Chinese regulatory ethics puts morality in the first place,using morality to replace regulatory systems.The distinctions of cultures and the sense of justice between western and Chinese societies cause the different viewpoints in relevant systems and regulations.

Objective To investigate the effects of 2-(3carboxy-1-oxoprogy1)amino-2-deoxy-D-glucose(COPADG) on the proliferation and cell cycle of human esophageal cancer cells Eca-109 and TE-1.Methods In vitro experiments,MTT colorimetric assay was performed to determine the growth inhibitory rates of Eca-109 and TE-1 cells treated by COPADG.Flow cytometry was applied to observe the change of cell proliferation cycle and apoptosis index.Cell morphological change was observed by transmission electron microscopy.Results COPADG inhibited effectively the growth of esophageal cancer cells Eca-109 and TE-1 in a time-and dose-dependent manner(P

To investigate the application of the teaching model of disease-based PBL combined with the interest group in clinical ophthalmology teaching. A clinical ophthalmology interest group was set up among interns and a PBL teaching with the theme of a single disease was carried out. The students demonstrated group presentation and discussion, and finally the teacher made comments in combination with clinical experience. The results shows that students' feedback was good. It has mobilized students' enthusiasm and initiative and can be used as a transition for carrying out PBL teaching complement to the traditional teaching model and be applied to the clinical ophthalmology teaching.

Objective To observe the effect of Da Jianzhong Decoction on cerebral cyclooxygenase-2 (COX-2) mRNA and protein and calmodulin-dependent protein kinase II(CaMKⅡ) mRNA in spleen-yang deficiency pain rats, so as to investigate the therapeutic mechanism of Da Jianzhong Decoction for spleen-yang deficiency pain. Methods Forty SD rats were randomly divided into normal group, model group, and high-and low-dose Da Jianzhong Decoction groups(3, 0.75 g·kg-1·d-1), 10 in each group. Spleen deficiency rat model was established by comprehensive modeling methods. After the rats in various groups were given gastric administration of Chinese medicine for 15 continuous days, rat cervical dislocation was performed for the sampling of the brain tissue. The expression levels of COX-2 mRNA and CaMKⅡmRNA in brain tissue were detected by real time polymerase chain reaction (RT-PCR). The COX-2 protein expression was determined by immunohistochemistry. Results Compared with the normal group, mRNA and protein expression levels of COX-2 in rat brain tissue of spleen-yang deficiency model group were increased(P﹤0.01), and CaMKⅡ mRNA expression was decreased (P<0.01). Compared with the model group, COX-2 mRNA and protein expression levels were decreased(P<0.01) and CaMKⅡexpression was increased(P<0.01) in high-and low-dose Da Jianzhong Decoction groups(P<0.01). Conclusion Da Jianzhong Decoction can suppress cerebral COX-2 mRNA and protein expression, and up-regulate CaMKⅡmRNA expression, which probably contribute to its therapeutic mechanism for relieving the pain.

Extracellular matrix plays an important role in maintaining organic structure and function, cellular proliferation and differentiation of normal aorta. Extracellular matrix proteolysis and remodeling of aortic wall resulting from degradation of matrix proteins characterize abdominal aortic aneurysm (AAA). Matrix metalloproteinase and its inhibitor have been implicated as potentially important in this disease, and MMP/TIMP ratios may be the key of AAA formation and development.

Objective To investigate the application value of warming humidification oxygen therapy in patients after tracheotomy.Methods Forty-one patients after tracheotomy were collected consecutively for this study.All patients were randomly assigned into the treatment group (21 cases)and the control group (20 cases).The treatment group adopted warming humidification oxygen therapy,and the control group adopted common airway moistening method.Moist effect judgment,viscosity of sputum,phlegm scab formation,respiratory irritation symptoms,airway mucosal bleeding,air way resistance,lung infection cases,average days in the ICU were investigated.Results There were statistically significant differences in moist effect judgment,viscosity of sputum,phlegm scab formation,respiratory irritation symptoms,airway mucosal bleeding,air way resistance,lung infection cases,average days in the ICU between the two groups.Conclusions Warming humidification oxygen therapy is more suitable to patients with tracheotomy than common airway moistening method.

In coloreetal cancer,there are multiple abnormally expressed microRNA (miRNA),suggesting that the miRNA may be involved in tumor development process.Recently,more and more evidence shows that miRNA are more stable in the blood,compared with mRNA,which makes circulating miRNA are helpful to become the non-invasive tumor marker for the diagnosis,treatment and prognosis evaluation in coloreetal cancer.

Voluntary control of saccadic eye movements is a kind of saccades controlled by conscious and always used to investigate the brain areas related to saccades and ability of response inhibition and work memory.Researching the neural mechanisms of voluntary control of saccadic eye movements could provide a basis to study the advanced cognitive function of brain and facilitate to explore basic neural mechanisms of abnormal saccadic in brain disorders.As neuroimaging technologies develops,intensive studies about the neural mechanisms of voluntary control of saccadic eye movements have been made great progress.It is showed that several brain areas such as prefrontal cortex,subcortical areas and parietal cortex mainly in participate.These multiple brain regions are involved in voluntary control of saccadic eye movements at different stages.Antisaccades and memory-guided saccades including different brain regions because of their different characteristics of saccadic.The future direction of the research is to combine study with neural imaging technology,and to study more about the brain regions and their functional connectivity involved in voluntary control of saccadic eye movements.
