Establishment and Evaluation of Animal Model of Acute Myocardial Infarction with Syndrome of Qi and Yin Deficiency / 中国实验方剂学杂志

ObjectiveTo explore the establishment and evaluation methods of the rat model of acute myocardial infarction （AMI） in coronary heart disease with the syndrome of Qi and Yin deficiency by sleep deprivation （SD） combined with isoproterenol （ISO） and preliminarily explore its biological basis. MethodForty SD rats were assigned into normal （no treatment）， SD （treatment in modified multi-platform water environment for 96 h）， ISO （subcutaneous injection of ISO at 100 mg·kg-1 once every other day for a total of 2 times）， and SD+ISO （injection of 100 mg·kg-1 ISO after SD for 72 h and 96 h） groups. The cardiac function was detected by small animal echocardiography. The serum levels of creatine kinase （CK）， creatine kinase isoenzyme （CK-MB）， lactate dehydrogenase （LDH）， and cardiac troponin T （cTnT） were measured by biochemical methods. The pathological changes of the myocardial tissue were observed by hematoxylin-eosin staining. The general state， body weight， grip strength， body temperature， behaviors in open field test， serum levels of cyclic adenosine monophosphate （cAMP）， cyclic guanosine monophosphate （cGMP）， cAMP/cGMP ratio， red （R）， green （G）， blue （B） values of the tongue surface， and pulse amplitude were observed and measured to evaluate the modeling results. Enzyme-linked immunosorbent assay was employed to determine the serum levels of interleukin-18 （IL-18）， tumor necrosis factor-α （TNF-α）， superoxide dismutase （SOD）， malondialdehyde （MDA）， corticotropin-releasing factor （CRF）， adrenocorticotropic hormone （ACTH）， triiodothyronine （T3）， tetraiodothyronine （T4）， cluster of differentiation 4 （CD4）， and cluster of differentiation 8 （CD8）. ResultIn terms of disease indicators， the ISO and SD+ISO groups had lower cardiac function indicators than the normal group （P<0.01）. The levels of CK， CM-MB， LDH and cTnT elevated in each model group compared with the normal group （P<0.01）. The pathological changes of myocardial tissue were obvious in the ISO and SD+ISO groups. In terms of syndrome indicators， compared with the normal group， the SD and SD+ISO groups showed decreased body weight at each time point （P<0.01）， and the ISO group showed decreased body weight at the time points of 48 h and 72 h （P<0.05， P<0.01）. The paw temperature and rectal temperature increased in the SD group （P<0.01）. The model groups showed weakened grasp strength， lowered R， G， and B values of the tongue surface （P<0.01）， prolonged immobility time （P<0.01）， reduced total distance and number of entering the central area （P<0.01）， decreased average speed （P<0.05， P<0.01）， and increased cAMP and cGMP （P<0.05， P<0.01）. The cAMP/cGMP ratio was increased in the SD+ISO group （P<0.01）， and the pulse amplitude was decreased in the SD and SD+ISO groups （P<0.01）. In terms of serological indicators，compared with the normal group， the levels of IL-18， TNF-α， SOD and MDA were significantly increased in the ISO and SD+ISO groups （P<0.01）， the CRF， ACTH， CORT， T3， T4， CD4 and CD8 in the model groups were increased （P<0.05， P<0.01）. ConclusionSleep deprivation for 96 h combined with high-dose ISO can successfully establish a rat model of acute myocardial infarction in coronary heart disease with the syndrome of Qi and Yin deficiency. The model evaluation system can be built with disease indicators of western medicine， histopathological indicators， macroscopic indicators of traditional Chinese medicine， and serological indicators.

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.

Establishment and Evaluation of Rat Model of Acute Coronary Syndrome with Combined Blood Stasis and Poison / 中国实验方剂学杂志

ObjectiveTo compare the feasibility of establishing the rat model of acute coronary syndrome with combined blood stasis and poison by lipopolysacharide （LPS） injection， ligation of coronary artery and different combinations of the two methods. MethodA total of 225 male SD rats were randomly divided into sham operation group， simple coronary artery ligation group， first injected LPS group ［LPS（5 mg·kg）injection 24 h before coronary artery ligation］ and follow injected LPS group ［LPS（5 mg·kg）injection 10 min after coronary artery ligation］. The indexes of each group were detected at 3， 24， 72 h after modeling， and the model was comprehensively evaluated. The general state and macroscopic evaluation indexes of traditional Chinese medicine （TCM） syndrome （tongue and pulse） of rats in each group were observed. ECG and echocardiography were used to evaluate cardiac function， and the myocardial ischemia and infarction areas were measured by Evans blue/2，3，5-triphenyltetrazolium chloride （TTC） staining. The content of creatine kinase isoenzyme （CK-MB）， lactate dehydrogenase （LDH）， creatine kinase （CK）， and troponin T （cTnT） in serum as well as interleukin-1 β （IL-1β） and IL-6 changes were determined by biochemical method or enzyme-linked immunosorbent assay （ELISA）. Hematology analyzer was adopted to determine the white blood cell （WBC） count， and the four coagulation indexes， platelet aggregation rate， hemorheology and other coagulation evaluation indexes were also detected. The myocardial tissue was observed by hematoxylin-eosin（HE）staining. ResultAfter 3 h of modeling， compared with the conditions in sham operation group， the R， G and B values of tongue of rats （P<0.01）， pulse amplitude （P<0.01）， and cardiac function in simple coronary artery ligation group were decreased， and the color of hypoglossal veins became purple（P<0.01）. The content of CK， LDH， cTnT， IL-1β and IL-6 in serum（P<0.05）， myocardial infarction area（P<0.01）， and total number of WBCs （P<0.05）were increased. Compared with simple coronary artery ligation group， first injected LPS group and follow injected LPS group had increased hypoglossal veins， decreased R value of tongue and elevated cTnT content （P<0.01）， while follow injected LPS group had reduced B value of tongue， decreased cardiac output （CO）（P<0.05）， increased IL-1β content， and thinned left ventricular anterior walls at end-systole （LVAWs）（P<0.01）. After 24 h of modeling， compared with sham operation group， simple coronary artery ligation group presented significantly decreased R， G and B values of tongue， lengthened purplish dark hypoglossal veins （P<0.01）， reduced pulse amplitude（P<0.01） and cardiac function， enlarged myocardial infarction area（P<0.01）， increased whole blood viscosity， platelet aggregation rate， fibrinogen （FIB）， shortened prothrombin time （PT） and thrombin time （TT）（P<0.01）， and elevated total number of WBCs （P<0.01）and content of CK， LDH， cTnT and IL-6 in serum（P<0.05）. Compared with the conditions in simple coronary artery ligation group， the pulse amplitude， R， G and B values of tongue （P<0.01）， and ejection fraction （EF） and fractional shortening （FS） scores （P<0.05）dropped， and hypoglossal veins were deepened and lengthened（P<0.05）， and cTnT content was increased（P<0.01）in first injected LPS group and follow injected LPS group. However， follow injected LPS group had thinned LVPWs， increased LDH content， platelet aggregation rate（P<0.05）， myocardial infarction area， and total number of WBC， level of IL-1β（P<0.05）， and shortened TT（P<0.01）. Additionally， 72 h after modeling， compared with sham operation group， simple coronary artery ligation group showed significantly reduced pulse amplitude， lowered R， G and B values of tongue， thickened and lengthened hypoglossal veins（P<0.01）， decreased cardiac function， and increased content of cTnT， FIB， whole blood viscosity（P<0.01），platelet aggregation rate， level of IL-6 and IL-1β（P<0.05）. Compared with the conditions in simple coronary artery ligation group， the hypoglossal veins of the first injected LPS group and the follow injected LPS group were more purple， and the content of cTnT was boosted（P<0.01）， whereas follow injected LPS group had decreased pulse amplitude， R， G and B values of tongue， EF and FS scores （P<0.05）， and enlarged myocardial infarction area（P<0.01）. ConclusionCompared with the other modeling methods and models at different modeling time， the established model by LPS injection 10 min after coronary artery ligation for 24 h was more consistent with the clinical characteristics of acute coronary syndrome with combined blood stasis and poison.

Chronic heart failure due to Qi deficiency and blood stasis and intervention mechanism of Compound Renshen Buqi Granules:a proteomics-based study / 中国中药杂志

Compound Renshen Buqi Granules have been widely used to treat chronic heart failure(CHF) due to Qi deficiency and blood stasis, but the mechanism of action remains unclear. This paper explored the pathogenesis of CHF due to Qi deficiency and blood stasis and the intervention mechanism of Compound Renshen Buqi Granules based on quantitative proteomics for uncovering the biological basis. SD rats were divided into the normal control(N) group, normal+Compound Renshen Buqi Granules(ND) group, model(M) group, model+Compound Renshen Buqi Granules(D) group, and positive control(Y) group. The rat model of CHF due to Qi deficiency and blood stasis was established by ligation of the left anterior descending(LAD) coronary artery and chronic sleep deprivation. The rats in the ND group and D group were provided with Compound Renshen Buqi Granules, while those in the Y group received valsartan. Six weeks later, the serum was sampled and the data-dependent acquisition(DDA) was employed for the non-targeted quantitative proteomics analysis of the differences in protein expression among groups, followed by the targeted analysis of differentially expressed proteins(DEPs) generated by data-independent acquisition(DIA). Compared with the N group, the rats in the M group pre-sented with decreased body weight, grip strength, and pulse amplitude and increased RGB value on the tongue surface. The pathomorphological examination revealed inflammatory cell infiltration, cell degeneration and necrosis, tissue fibrosis, etc. After the intervention with Compound Renshen Buqi Granules, multiple indicators were reversed. As demonstrated by proteomics results, there were 144 and 111 DEPs found in the M group and ND group in comparison with the N group. Compared with the M group, 107 and 194 DEPs were found in the D group and the Y group, respectively. Compared with the ND group, 119 DEPs were detected in the D group. As illustrated by DIA-based verification, the quantitative results of six proteins in each group were consistent with those by DDA. The syndrome indicators and pathomorphological examination results demonstrated that the protein expression profile of rats with CHF due to Qi deficiency and blood stasis changed obviously. However, Compound Renshen Buqi Granules were able to reverse the differential expression of immune proteins to regulate CHF of Qi deficiency and blood stasis syndrome, which has provided clues for figuring out the pathogenesis of CHF due to Qi deficiency and blood stasis and the intervention mechanism of Compound Renshen Buqi Granules.

Study on construction of rat model of acute pancreatitis with syndrome of liver depression and Qi stagnation / 中国中药杂志

The aim of this paper was to construct a rat model of acute pancreatitis(AP) with syndrome of liver depression and Qi stagnation, and provide evaluation tools for pharmacodynamic research and efficacy network verification of related traditional Chinese medicine in view of the etiology, pathogenesis and clinical manifestations of AP. According to the Chinese and Western medicine diagnosis and treatment guidelines for AP with syndrome of liver depression and Qi stagnation, etiology, pathogenesis and clinical syndromes in TCM, Meta-analysis results, and evaluation strategy of establishing an animal model combining disease and syndrome in our laboratory, the biological surrogate outcomes suitable for the evaluation of animal models of AP with syndrome of liver depression and Qi stagnation were extracted then. The chronic unpredictable stress(CUS) method and chronic unpredictable stress +L-arginine(CUS +L-Arg) method were used to construct the rat model, and the above biological surrogate outcomes were used to evaluate whether an AP rat model was established. During the experiment, the weight and syndrome scores of the rats were observed and recorded. At the end of the experiment, the rats' serum, organs and tissues were collected from the operation to detect the various indicators. As compared with the normal group, the syndrome scores of the CUS group and CUS +L-Arg group were significantly increased(P<0.01); the anti-syndrome medicine Chaihu Shugan Pills could significantly reduce the syndrome scores of the two groups of rats(P<0.01), indicating that both modeling methods can replicate the syndrome of liver depression and Qi stagnation in the rat model. As compared with the normal group, the serum amylase(AMY) activity level was increased by 3 times in the CUS +L-Arg group(P<0.01), and the AMY activity level was also increased in CUS group, but not up to 3 times of the normal value. As compared with the normal group, the le-vels of TNF-α and IL-6 mRNA in the pancreatic tissues of the CUS +L-Arg group were significantly increased(P<0.01); the levels of TNF-α mRNA in the pancreatic tissues of the CUS group were significantly increased(P<0.05), but IL-6 mRNA level only showed a rising trend, indicating that only the CUS + L-Arg method can be used to replicate the AP damage in the disease-syndrome combination model. The CUS + L-Arg method can be used for continuous modeling for 4 weeks to establish a disease-syndrome combination model of AP rats with syndrome of liver depression and Qi stagnation. The model has the characteristics of repeatability, stability after mode-ling, low animal mortality, and similar clinical pathogenesis. It can be used for the evaluation of traditional Chinese medicine efficacy and the verification of efficacy network.

Disease-syndrome combination in integrated traditional Chinese and Western medicine in andrology: Confusions and countermeasures in studies / 中华男科学杂志

Researches on the mechanisms underlying the therapeutic effects of the disease-syndrome combination approach in integrated traditional Chinese and Western medicine are becoming a hot spot in andrology, but many recent studies of this kind have failed to explain the connotation of integrated traditional Chinese and Western medicine in andrology. Related existing problems include repeated researches into the same indexes of action mechanisms of different therapeutic principles of traditional Chinese medicine (TCM), Chinese herbal compound and special prescriptions, studies focusing on individual diseases but ignoring symptoms, immature syndrome models for studies of mechanisms, and too much attention to uncertain or immature target mechanisms. The stress should be placed on the action mechanisms of Chinese herbal compound and special prescriptions on male diseases and, what is more important, on the clarification of the essential principles of differentiation and treatment of TCM syndromes. In the recent years, proteomics, genomics, transcriptomics and metabolomics have shed some light upon researches into the mechanisms underlying the therapeutic effects of the disease-syndrome combination approach in integrated traditional Chinese and Western medicine in andrology. An insight into the TCM syndrome, a macroscopic inductive analysis, and a comprehension of such microcosmic aspects as the gene, protein, metabolism and metagenome may contribute to some breakthroughs and new ideas in the studies of disease-syndrome combination in integrated traditional Chinese and Western medicine in andrology.

Randomized Controlled Study of Disease-syndrome Combination Therapy for Anovulatory Infertility / 广州中医药大学学报

Objective To investigate the clinical effectiveness of disease-syndrome combination therapy for anovulatory infertility through randomized controlled trial, thus to provide high-level evidence-based medical reference for the diagnosis and treatment of WHO typeⅡovulation disorder infertility. Methods Eighty-six patients with WHO typeⅡovulation disorder infertility were randomized into treatment group and control group , 43 cases in each group. Both groups were given the treatment for correcting endocrinic disorder if necessary. Additionally, by following the principle of combination of disease differentiation and syndrome differentiation , Zhuyun Recipe 1, Zhuyun Recipe 2, and Zhuyun Recipe 3 were separately given orally to the patients with kidney-yang deficiency (WHO type Ⅱ ovulation disorder without PCOS), patients with liver-kidney insufficiency(WHO typeⅡovulation disorder complicated with hyperandrogenitic lean-PCOS),and patients with kidney-deficiency complicated with phl egm-dampness (WHO type Ⅱ ovulation disorder complicated with insulin-resistant obesity-PCOS) in the treatment group respectively. The patients in the control group was given oral use of the first-rate ovulation induction drug Clomiphene. The treatment covered 3 menstruation cycles. Ovulation rate,pregnancy rate and alive fetus rate were used as the indicators for evaluating the effectiveness,and the safety was also monitored. Results(1)Of the 86 cases,5 cases dropped out(loss to follow-up or being excluded),with the drop-out rate being 6%. Of the 5 drop-out cases,3 were from the control group,and 2 were from the treatment group. (2)Ovulation rate of the treatment group was 70.7%,and that of the control group was 85.0%. The ovulation rate of the two groups was enhanced,but the difference between the two groups was insignificant(P > 0.05).(3)Pregnancy rate of the treatment group was 51.2%,and that of the control group was 30.0%, the differen ce being significant between the two groups(P < 0.05).(4)Alive fetus rate of the treatment group was 45.2%,and that of the control group was 22.5%,the difference being significant between the two groups(P < 0.05).(5)No adverse reaction was found in the two groups during the treatment. Conclusion The disease-syndrome combination therapy for WHO type Ⅱanovulatory infertility shows the advantages of higher pregnancy rate and alive fetus rate, which makes up for the disadvantages of low pregnancy rate and high abortion rate of Clomiphene.

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.
