Animal Model of Cold Congeal and Blood Stasis Syndrome： A Review / 中国实验方剂学杂志

The cold congeal and blood stasis syndrome is a common clinical traditional Chinese medicine（TCM） syndrome. The animal model of cold ongeal and blood stasis syndrome is the basis for exploring the essence of TCM cold congeal and blood stasis syndrome，and the premise of follow-up TCM clinical research.This paper summarized the preparation method， theoretical support，and evaluation method of animal models of cold congeal and blood stasis syndrome in recent years and analysed the strengthens and weaknesses of different models. At present，the common animal models of cold congeal and blood stasis syndrome mainly include etiological model，etiological and pathological composite model and disease-syndrome combination model. The etiological model was mainly prepared by cold exposure，which could be divided into whole-body freezing， ice bath and local frostbite. The etiological and pathological composite model was mainly prepared by cold stimulation combined with epinephrine injection. The common disease-syndrome combination models included the coronary heart disease model of cold congeal and blood stasis syndrome，primary dysmenorrhea model of cold congeal and blood stasis syndrome，endometriosis model of cold congeal and blood stasis syndrome， and arteriosclerosis obliterans model of cold congeal and blood stasis syndrome. The three models have both advantages and disadvantages. Specifically， the disease-syndrome combination model had the highest consistency with clinical practice and was more reliable and practical. However， the disease types of this model were specific，and the combination method of disease and syndrome was controversial. The evaluation indicators of the animal models of cold congeal and blood stasis syndrome focused on the characterization of the syndrome and the physico-chemical indicators related to blood flow，such as blood rheology，coagulation function and microcirculation. In addition， some scholars explored the evaluation indicators from the aspects of vasomotor function，endocrine and energy metabolism. The objectivity and specificity of the current model evaluation methods needed to be further improved. The research of animal model of cold congeal and blood stasis syndrome should be based on clinical practice and oriented by clinical demand. Only by establishing animal models that are highly consistent with the characteristics of clinical disease and syndrome can we better reveal the essence of cold congeal and blood stasis syndrome and promote the modernization of TCM.

A glucose-insulin-potassium solution improves glucose intake in hypoxic cardiomyocytes by a differential expression of glucose transporters in a metabolic syndrome model

Among the last consequences of metabolic syndrome are cardiovascular complications such as infarcts. The hypoxic heartswitches its lipid-based metabolism to carbohydrates, and a glucose-insulin-potassium (GIK) solution can be the metabolicsupport to protect the organ. Due to the physiology and cardiac risks associated with the metabolic syndrome, we studied theeffect of GIK solution during hypoxia in a metabolic syndrome model by observing the participation of glucose transporters(GLUTs). The metabolic syndrome characteristics were established by giving a 30% sucrose drinking solution to Wistar ratsfor 24 weeks. The GIK solution’s effect on myocyte glucose uptake during hypoxia and oxygenation was observed using acolorimetric method, and Western blot technique visualized the GLUT participation. Oxygenated control myocytes consumed1.7 ± 0.2 µg of glucose per gram of fresh tissue per hour using the GLUT1, and during hypoxia, they incorporated 41.1%more glucose by GLUT1 and GLUT4. The GIK solution improved glucose uptake in oxygenation by 70.5% through GLUT1.In hypoxia, the uptake was 21% more than the hypoxic control group and by both GLUTs too. Oxygenated metabolicsyndrome myocytes uptake was similar to control cells but achieved by both carriers in oxygenation and hypoxia. Also, theGIK solution had a better response in both oxygenation (113%) and hypoxia (71%). Despite the metabolic energy disorders ofthis syndrome, the GIK solution protects cardiomyocytes, in conditions of hypoxia, through the modulation of both GLUTs.So, this solution can be considered a useful resource during a heart attack in cases of metabolic syndrome.

Study on establishment of an animal model of Qi deficiency syndrome base on theory of over exertion leading to Qi consumption in traditional Chinese medicine / 中国中药杂志

Based on the theory of "overexertion leading to Qi consumption", this study aimed to compare the intervention factors of nervous and physical fatigue to establish a rat model of Qi deficiency syndrome, moreover, the systematic evaluationsystem was necessary with the standard of syndrome diagnosis of Qi deficiency. According to the clinical-mimetic principle the Qi deficiency syndrome animal model is established by the factors of sleep deprivation(SD) and exhaustive swimming(ES). Rats were randomly divided into four groups, normal group, SD group, ES group and compound group (exhaustion swimming complex sleep deprivation). The method of ES was force rats to swim until the exhaustion with 5% of weight, and the SD method by using multi-platform sleep deprivation of water environment randomly 14-16 h daily, and the complex set by using of two methods was combined. The movement distance, average speed, activity time and numbers into the central area were detected by open field test, swimming exhaustion time was detected by swimming exhaustion method, the cardiac function (LVEF, CO, FS, LVDd) was detected by echocardiography, tongue imaging analysis and pulsedistention as the index of tongue and pulse diagnosis, the content of ATP and ADP in serum was detected by ELISA, the blood coagulation indexes for blood stasis syndrome as the additional. These results indicated that independent activity, body weight and exercise capacity were decreased significantly, the neurological function injured significantly, heart function was decreased significantly, the tongue surface color was pale white, and the pulse distention was decreased significantly. The content of ATP decreased significantly and the ADP increased significantly. By the method of four-diagnostic evaluation system to compare the factors of SD and ES, the Qi deficiency syndrome animalmodel could be successfully established by sleep deprivation method.

Methods to establishment of serum induced syndrome of liver-depression and spleen-deficiency cell model / 中国中药杂志

To explore the method of establishing a cell model of traditional Chinese medicine (TCM) syndromes, HepG2 cells were induced by human serum of liver-depression and spleen-deficiency syndrome(LDSDS) to establish a cell model of LDSDS in this research. The concentration of cells, the content of human serum in culture medium and the growth characteristics of model-cell (cell growth curve, the survival rate and apparent morphology were investigated by MTT assay and microscopy. Evaluation of syndrome cell model: metabolomics was used to analyze the human serum of normal individuals and patients with LDSDS, and cell models induced by these serums, respectively. We obtained the difference metabolites from serums and cell models of LDSDS, respectively; then compared the biomarkers from two metabolomics and their metabolic pathways, to verify that the reliability and applicability of the model. Metabolomics data were collected by UPLC-Q-TOF-MS, and then all data were analyzed by multivariate statistical (PCA，OPLS-DA). The results showed that, model cells have the characteristics of normal growth, slow proliferation and stable morphological structure inducted by 10% serum of LDSD in 24-72 h. There were the same 19 difference metabolites which from the human serum of normal individuals and patients with LDSDS, and cell models induced by these serums; including 9 metabolic pathways that play an important role in maintaining normal physiological activities of the human body, such as lipids, amino acids, nucleotides, and energy metabolism etc. It was shown that the established syndrome cell model can reflect the biological basis of LDSDS to some extent. This research provides a reference method for the establishment of TCM syndrome cell model.

Advantages, Disadvantages and Sticking Points of Traditional Chinese Medicine Animal Syndrome Models And Disease-syndrome Combination Models / 世界科学技术-中医药现代化

Studies showed that animal model of the so-called simple syndrome currently have corresponding modern medical disease without exception. Even such animal model is called simple syndrome model, its properties is a cer-tain modern medicine disease. There is no specific corresponding relationship between the syndrome-attribution and the syndrome. The signs and symptoms differentiation and abnormal physical and chemical detection indices after pathogen-modeling of traditional Chinese medicine (TCM) cannot be determined since there are no specific corre-sponding relationships. The study on disease-syndrome combination model contains both modern medical modeling method and TCM modeling method. This type of modeling method has its own existing shortcomings. Meanwhile, two modeling methods used in the model establishment have uncertain relationship. The disease-syndrome combination model is usually not established in the comparison among different syndromes of one disease. Therefore, it has no ex-clusive attribute. There are many problems existed in the TCM modeling method, disease-syndrome combination modeling method, and syndrome-attribute evaluation methods. The basic reasons are the wide difference between symptoms and signs for diagnosis in modern medicine disease. There are a few symptoms and signs for diagnosis in modern medicine. But there are much more symptoms and signs for syndrome differentiation of the same disease. Many symptoms for syndrome differentiation are unknown for its source of origin existed in a virtual state. It caused that many virtual syndromes abstracted by virtual symptoms, and was reflected by the relevant standards. It leads to devastating consequences for the development of animal modeling method.
