Some researchers focus on research of the nature of syndromes. The methods of combining traditional Chinese medicine syndrome and diseases and the correspondence between formulas and syndromes may be used in research of the nature of syndromes. According to combined theories of zang-organ state and seven emotions in traditional Chinese medicine with stress theory in modern medicine, the authors applied the methods of chronic immobilization stress to induce liver depression and spleen deficiency syndrome in rats based on the thinking of relativity on formula and syndrome. The research showed that the central neurobiology mechanism of liver depression and spleen deficiency syndrome closely correlates to the hypothalamic-pituitary-adrenal axis, brain-gut axis, myriad central neurotrophic factors, neurotransmitters, neuropeptides and hormones and their receptors, involving in many encephalic regions such as the hypothalamus, hippocampus, cortex, amygdale, etc. The authors will combine their previous work with multi-disciplinary research, such as genomics, proteomics, metabolomics and bioinformatics in future studies, to reveal the scientific connotations of liver depression and spleen deficiency syndrome.

BACKGROUND: The application of adipose derived stromal cells to tissue engineering has been more and more popular around the world. Compatibility of scaffold material is the key point for its further research.OBJECTIVE: To determine the growth rules of rabbit adipose-derived stromal cells with polylactic-co-glycolic acid (PLGA).DESIGN, TIME AND SETTING: An in vitro study was performed at the Institute of Ophthalmology, Otolaryngology Hospital,Fudan University and Shanghai Tissue Engineering Center from September 2007 to March 2009.MATERIALS: Six female New Zealand rabbits aged six months were used for extraction of adipose-derived stromal cells. PLGA was provided by Sigma, USA.METHODS: Adipose tissue was harvested from the nape fat pad of the rabbits following anesthesia. Primary cultured cells were established using type I collagenase and cell cultures were maintained with DMEM containing 10% volume fraction of fetal bovine serum. Cells were passaged when 80% was confluent. The fourth passages of cells were utilized for the study. PLGA consisted of polylactic acid and polyglycolic acid as the ratio of 7:3, and the relative molecular mass was 104900.MAIN OUTCOME MEASURES: Initially, the adherent rate of cells to scaffold was detected. After one week co-culture, the scaffold bearing adipose-derived stromal cells labeled with Dio agent were investigated by fluorescence inverse microscope,scanning electron microscopy and laser scanning microscope.RESULTS: The best adherent rate of adipose-derived stromal cells with PLGA reached 99%. After one-week-incubation in vitro,cells of fiber-shaped or ovule-shaped proliferated well and exhibited stratified growth on the surface of PLGA scaffold. In addition,it also secreted visible extracellular matrices, which could be examined by scanning electron microscopic examination.Meanwhile, the adipose-derived stromal cells grew well and distributed equably inside the PLGA in terms of the investigation with laser scanning microscope.CONCLUSION: The compatibility of adipose-derived stromal cells to PLGA in vitro was well.

Xiang-thinking is the main way of thinking in the form of traditional Chinese culture, which included Xiang and thinking. In viscera theory of traditional Chinese medicine(TCM) formation, Xiang-thinking has run through and played a role in pushing forward on the formation of manifestation theories. Among five internal organs, take liver as an example. The formation of the liver manifestation is through the description of the liver and intuitive form and structure of the object, which were on the basis of the extract of abstract thinking, and the summarization on rules of the process. In this paper, the formation of liver manifestation theory was taken as an example to discuss the application of Xiang-thinking in formation of liver manifestation theory.

Objective: Pervious RT-PCR results revealed the possibility of effective regulation channel of Xiaoyao San in treating rats of syndrome of liver invading the spleen. This experiment was designed to explore CIS rats’ immunohistochemistry findings in hippocampal subregion CA1 and amygdaloid subregion BLA after suppressing both amygdaloid AMPA receptors by microinjection of CNQX. To compare Xiaoyao San group with CNQX group, and to analysis of these findings may prove the possibility of effective regulation channel of Xiaoyao san treating this syndrome. Methods: 75 male SD rats were randomly divided into 5 equal groups: normal group, CIS group, sham-operation group, CNQX group and Xiaoyao San group. The number of GluR2 positive cells in hippocampal subregion CA1 and amygdaloid subregion BLA in these 5 groups were examined by immunohistochemistry test. Results: Compared with control group, the number of GluR2 positive cells decreased in hippocampal subregion CA1. Statistical analysis showed that no difference existed in control, CNQX and Xiaoyao San groups in CA1 region. Except CNQX group, tendency of changes were contradictory in BLA and CA1 region. In addition, the least in BLA in CNQX group. This finding revealed that Xiaoyao San may act the same as CNQX, thus Xiaoyao San afforded effective protection against this depression syndrome through suppression of both amygdaloid excitability. Conclusion: The balance coordination between hippocampus and amygdala may be the key in transformation from adaption to damage in a state of stress, was one of the central mechanisms of liver governing smoothing qi flow (LGSQF) on regulating the stress. Xiaoyao San may effectively regulate the balance of the excitability of hippocampus and amygdala. This hypothesis may reveal the regulation channel on Xiaoyao San affording effective protection against liver invading the spleen syndrome.

In this study,adults of Armillifer agkistrodontis (A.agkistrodontis) were collected from Agkistrodon acutus,and then the eggs were separated to feed mice.In the next step,when the infection model was established,blood serum of infected mice were collected after 1,2 and 3 weeks,respectively.Furthermore,ELISA and dot- ELISA were used to detect the dynamic change of specific antibodies and circulating antigens respectively.The specific antibodies increased from 8th week,reached the top at 12th week,decreased from 16th week,and then maintain at the same level constantly.Meanwhile,the specific antibodies were typed.It is evident that IgM antibody appeared first.However,it was substitute by IgG1 after 16 weeks.Moreover,the circulating antigens have been detected in the 1st week by dot-ELISA.Then,the dilution between 1:8 to 1:128were founded in 3rd week.The highest dilution with 1:256 appeared at 8th week,maintained before 11th week and then decreased gradually,which might provide a significant clinical implication for early diagnosis of circulating antigens.

Objective To evaluate the rat model of type 2 diabetes mellitus ( T2DM) associated with depres-sion by body weight, fasting blood glucose, manifestations, and open field test.Methods The T2DM rat model was induced by high fat diet and low dose of STZ injection, and in addition, the T2DM rats were made restraint stress for 21 days.32 Wistar rats were randomly divided into three groups: normal group ( group N) , T2DM group ( group T)and T2 DM with depression group ( group T +D) , with 8 rats in each group.After the model was established, to measure the body weight, fasting blood glucose at day 0, 7, 14, and 21, and observe the gross manifestations, drink-ing and diet, feces, urine, and mental state, and test the rat depression by open field test.Results After establish-ment of the T+D rat model, the rats in group T+D showed some symptoms, including messy dark and gloomy hair, slow movement, increasing drinking, diet, feces and urine and mental fatigue.At day 0, 7, 14, and 21, compared with the group N, the body weight of the group T and group T+D were decreased, showing a significant difference ( P<0.05;P<0.01).At day 0, 7, 14, and 21, compared with the group N, and the fasting blood glucose in the groups T and T+D were increased, with a significant difference ( P<0.01 ) .After 21 days of restraint stress, the fasting blood glucose in the group T+D was significantly higher than that in the group T ( P<0.01 ) .Compared with the group N, the total movement distance in 5 minutes in the group T+D was reduced, but without a significant differ-ence (1532.6 ±126.8 cm vs.940.5 ±208.3 cm, P>0.05).Compared with the group N, the movement speed in 5 minutes in the group T was significantly slower than that in the group T , with a significant difference ( 5.1 ±0.4 cm/s vs.2.9 ±0.6 cm/s, P<0.05 ) , and even more slower than that in the group T +D, with a significant differ-ence (5.1 ±0.4 cm/s vs.2.4 ±0.5 cm/s, P<0.01) .Conclusions A rat model of type 2 diabetes mellitus as-sociated with depression has been successfully established by high fat diet and injection of low dose streptozotocin in combination with restraint stress for 21 days.This rat model is useful for further relevant studies.

Liver is no longer the only organ in the concept of anatomy,but it is a concept that has some specific functions in the visceral manifestations of liver.Liver is wood in the five element theory.It is yang of yin.Liver qi connects to the spring qi.Therefore,the liver function is to dredge and smooth qi of the whole body,which influences the blood and body fluid operation,the operation of the spleen and stomach,emotional changes and reproductive function and many other aspects.Suwen said "liver stores blood",which means that liver has the function of storing,regulating and controlling blood."Liver corresponds to the spring",which means changes in four seasons can affect the function of organs,but also contain the disease occurrence with a seasonal concept,which is an important part of visceral manifestation of liver.Modern medical research achieved some results from the nerve-endocrine-immune network,traditional four-axis,liver-blood vessels as the starting point for the liver as the theoretical mechanism of in-depth study.It was found that depression due to liver failed in soothing was related to the central cortex,the marginal system and the hypothalamicpituitary-adrenal (HPA) axis.The study covered neuropeptide and neurotrophic factor,monoamine neurotransmitter,central amino acid level,and etc.Liver stores blood,which is related to human coagulation system,EPO pathway and hemorheology.Liver corresponds to the spring,which is related to the neuroendocrine-immune network.And the pineal gland may be the highest regulatory site.At present stage,the study was conducted on the microcosmic mechanism of liver visceral manifestations from the gene and protein level.It was used to verify the regulation of liver function abnormality caused by the regulation of liver function in order to greatly explore the biological basis of traditional Chinese medicine (TCM) theory.
