Objective To introduce a proposal that can standardize the clinical information of urine manifestation in Chinese medicine.Methods A hypothesis of symptomatic units was proposed in this paper,herein,the attribute,name and definition of the symptomatic units of urine manifestations in the clinical records of Chinese medicine in the past dynasties were summarized according to the stipulation of logic classification and denomination of a scientific term.Results The 23 symptomatic units,2 bounds and their assembly can express 3867 descriptions on the clinical manifestation of urine.Conclusion The symptomatic unit is a feasible hypothesis that can simplify the clinical information of Chinese medicine.The attribute extraction,denomination and definition may become one of the effective procedures to standardize the clinical information of Chinese medicine.

OBJECTIVE: To probe into a construction model of TCM resource science meeting the need of teaching practice and fitting for teaching and education, which focuses on the both characteristics of TCM and nature of resource. METHODS: Guided by "the three basic key points" theory, the content of the construction of TCM resource science are analyzed, such as foundational theories, elementary knowledge and basic skills, etc., considering academic characteristics and position, write of textbook. RESULTS: Based on current demand, theory analysis, content of system and advantages of the construction of TCM resource science, the new idea characterized with teaching being harmonious with education was put forward and fit for "the three basic key points" theory. CONCLUSIONS: The construction model of TCM resource science is an efficient and technical way to meet the demand of teaching.

Alzheimer's disease (AD) is a progressive, degenerative disease of the brain, which causes learning and memory to become seriously impaired. AD not only influences the patient's quality of life, but also places a great burden on caregivers. With the increasing of aging population, the pressures can be wide-ranging, involving social, psychological, physical, and economic elements of the caregivers' life.The cause and progression of Alzheimer's disease are not well understood. Currently used treatments include pharmaceutical and psychosocial ones, each offering a small symptomatic benefit. Actually, there are still no available medicines and treatments to delay the progression of the disease. Therefore, the development of a new ideal medicine to treat AD patients becomes the first priority. In recent years, most researchers have turned to natural products, hoping to find a drug candidate to cure AD patient. Baicalein, a traditional Chinese medicine extracted from Scutellaria Baicalensis (Chinese herb), has been demonstrated holding the properties of anti-inflammatory, anti-apoptosis, anti-oxidant, and improving learning and memory of human brain. Baicalein is becoming a potential ideal medicine for treating AD patient.

In the opinion of dialectical materialism, concept is developing with the deepening and broadening of human being's mind. The developing process of syndrome concept in traditional Chinese medicine also takes the same way. In the Sui and Tang Dynasties, the connotation of syndrome concept was defined and the embryonic form of syndrome differentiation of zang-fu viscera was formed. In the Song, Jin and Yuan Dynasties, the development of syndrome concept embodied in optimizing the theoretical research based on clinical practice and experiences according to many medical masters in different denominations. The syndrome differentiation of eight principles was established to standardize and perfect the principles of syndrome differentiation in the Qing Dynasty. Modern research of syndrome concept is manifested in objectifying the process of research of syndrome and diseases in different levels and aspects by use of advanced scientific technology.

Objective To optimize the process of extracting total saponins from Platycodon grandiflorum by orthogonal experimental design and central composite design-response surface method. Methods Independent variables were concentration of ethanol, reflux extraction time, reflux time and solvent fold. Dependent variables were extraction rate of total saponins in Platycodon grandiflorum and the yield of dry extract.Linear or nonlinear mathematic models were used to estimate the relationship between independent and dependent variables. Results The result of the orthogonal experimental design was 70%ethanol, 180 min for reflux, 6 fold of solvent and 2 times for extraction. The result of central composite design-response surface method was 70% ethanol, 140 min for reflux, 10 fold of solvent and 2 times for extraction. Conclusion The central composite design-response surface method is better than orthogonal experimental design in studying extraction process of Platycodon grandiflorum, which provides basis for feasibility of application of central composite design-response surface method in optimization of extraction process of Chinese traditional medicine.

Objective To investigate mesenchymal stem cells genetically modified by nerve growth factor to repair acute spinal cord injury in rats. Methods Fifty six Wistar rats of inbred strain were randomly divided into sham operation group cell transplantation group and simple injury group. The spinal cord injury model was prepared according to the modified Allen's method. NGFβ (hNGFβ) and GFP genes were transfected into MSCs by replication-deficient recombinant adenovirus vector (Ad-hNGFβ) and replication-deficient recombinant retrovirus vector (Rt-GFP) respectively. GFP positive MSCs were transplanted into intradural space of injured spinal cord at 7 days after spina coral injury. Spinal cord was dissected at 24 h, 1 and 2 weeks after transplantation. To observe the expression of GFAP and nestin and the distribution of MSCs after transplantation following the spina corol injury. Results MSCs migrated to the injured parenchyma In transplantation group, the expression of GFAP and NGF protein was higher than in the control group (P<0.05), the BBB score in transplantation group was higher than that in the control group (P<0.05). Conclusion The MSCs transplantation repaired the injured spinal cord to some extent.

Gene chips can detect the expression of thousands of genes simultaneously.In this article,gene chips,as a screen apparatus and an imaging apparatus,were depicted according to its main uses.As a screen apparatus,in most researches,on account of different objects,the differential genes were screened by using experimental samples or tissues/cells on different times and different dosage;as an imaging apparatus,gene expression profile was used to discriminate different physiological and pathological characters in different tissue in order to diagnose a disease,which was good for vast data towards application.For bioinformatics analysis on data,at present,some cluster analyses such as non-supervised cluster,k-means and SOM are common analytical means,which presume the function of unknown genes by assisting experimental effects of chips through different algorithms,and judge pathogenesis,diagnose and treated target of diseases.In a word,gene chips is not only a kind of simple molecular biology technology,but also brings us from the period of acquiring knowledge to the period of dealing with information,which provides necessary preparation for researches from decomposed analysis to systemic biology.
