ABSTRACT
OBJECTIVE: To investigate the underlying protein molecular mechanisms of "Qi stagnation and blood stasis syndrome" (QS) and "Qi deficiency and blood stasis syndrome" (QD), as two subtypes of coronary artery disease (CAD) in Traditional Chinese Medicine (TCM), following percutaneous coronary intervention (PCI). METHODS: In this study, a total of 227 CAD patients with QS and 211 CAD patients with QD were enrolled; all participants underwent PCI. Label-free quantification proteomics were employed to analyze the changes in serum in two subtypes of CAD patients before and 6 months after PCI, aiming to elucidate the intervention mechanism of PCI in treating CAD characterized by two different TCM syndromes. RESULTS: Biochemical analysis revealed significant changes in tumor necrosis factor-α, high density lipoprotein cholesterol, blood stasis clinical symptoms observation, and Gensini levels in both patient groups post-PCI; Proteomic analysis identified 79 and 95 differentially expressed proteins in the QS and QD patient groups, respectively, compared to their control groups. complement C8 alpha chain, complement factor H, apolipoprotein H, apolipoprotein B, plasminogen, carbonic anhydrase 2, and complement factor I were altered in both comparison groups. Furthermore, enrichment analysis demonstrated that cell adhesion and connectivity-related processes underwent changes in QS patients post-PCI, whereas lipid metabolism-related pathways, including the peroxisome proliferator-activated receptor signaling pathway and extracellular matrix receptor interaction, underwent changes in the QD group. The protein-protein interaction network analysis further enriched 52 node proteins, including apolipoprotein B, lipoprotein (a), complement C5, apolipoprotein A4, complement C8 alpha chain, complement C8 beta chain, complement C8 gamma chain, apolipoprotein H, apolipoprotein A-â ¡, albumin, complement C4-B, apolipoprotein C3, among others. The functional network of these proteins is posited to contribute to the pathophysiology of CAD characterized by TCM syndromes. CONCLUSION: The current quantitative proteomic study has preliminarily identified biomarkers of CAD in different TCM subtypes treated with PCI, potentially laying the groundwork for understanding the protein profiles associated with the treatment of various TCM subtypes of CAD.

ObjectiveTo observe and compare the electrocardiogram index, myocardial morphology, and connexin 43 (Cx43) expression of two rat models of acute cerebral infarction (ACI) due to stasis combined with toxin complicated with cerebral-cardiac syndrome (CCS), and to provide experimental evidence for the research on the occurrence mechanism of cardiac diseases induced by ACI and the clinical diagnosis and treatment of CCS. MethodSixty SPF-grade male SD rats were randomized into six groups (n=10): normal , syndrome of stasis combined with toxin induced by carrageenin combined with dry yeast (CA/Y), multi-infarct induced by micro-embolism (ME), middle cerebral artery occlusion (MCAO), CA/Y+ME, and CA/Y+MCAO groups. The model of syndrome of stasis combined with toxin was established by intraperitoneal injection with carrageenan (CA) at 10 mg·kg-1 on the first day and subcutaneous injection with dry yeast (Y) suspension (2 mg·kg-1) on the second day of modeling. Twenty-four hours after the modeling of ACI, the electrocardiograms (ECGs) of rats in each group were collected and the number/percentage (%) of abnormal ECG was calculated. The infarct area of the brain was evaluated by 2,3,5-triphenyltetrazolium chloride (TTC) staining, and myocardial injury was assessed by hematoxylin-eosin (HE) staining. Immumohistochemical staining and Western blot were employed to determine the expression of Cx43 in the myocardium. ResultA certain number of rats in each model group presented abnormal ECG. Compared with the normal group and CA/Y group, CA/Y+MCAO group had the highest rate of abnormal ECG (P<0.01). Compared with the normal, CA/Y, ME, and CA/Y+ME groups, the CA/Y+ME and CA/Y+MCAO groups showed decreased amplitudes of P-wave and T-wave, shortened P-R interval, and extended Q-T interval, which were particularly obvious in the CA/Y+MCAO group (P<0.05, P<0.01) and in accordance with the cerebral infarction area and pathological changes. The expression of Cx43 was up-regulated in both CA/Y+ME and CA/Y+MCAO groups, especially in the CA/Y+MCAO group (P<0.01). ConclusionThe two rat models of ACI due to stasis combined with toxin complicated with CCS can be used to study the mechanism of heart diseases caused by cerebrovascular diseases and the therapeutic effects of Chinese medicines with the functions of resolving stasis and detoxifying. Moreover, the CA/Y+MCAO method has higher abnormal electrocardiogram rate, severer myocardial pathological injury, and higher expression of Cx43 protein. The models can be chosen according to specific experimental purpose.

ObjectiveTo explore the protective effect and mechanism of Zingiberis Rhizoma Recens alcohol extract on lipopolysaccharide (LPS)-induced acute lung injury in mice. MethodBalb/c mice were randomly divided into normal group, model group, dexamethasone group, and low- and high-dose Zingiberis Rhizoma Recens groups. Mice in the normal group were instilled with normal saline through the nose, and the other groups were instilled with normal saline containing LPS (50 μg). After 30 minutes of modeling, the dexamethasone group was gavaged with 5 mg·kg-1 of dexamethasone acetate solution, the low- and high-dose Zingiberis Rhizoma Recens groups were gavaged with different doses of (7, 14 g·kg-1) of Zingiberis Rhizoma Recens alcohol extract, and the normal group and the model group were gavaged with the same volume of water. After 24 hours of modeling, the total number of white blood cells in bronchoalceolar lavage fluid (BALF) was detected by cell counter, and the levels of the inflammatory factors including tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, and superoxide dismutase (SOD), and myeloperoxidase (MPO) was detected by enzyme-linked immunosorbent assay (ELISA). Haematoxylin-eosin (HE) staining method was used to observe the pathological changes of lung tissue in each group, and the Western blot was used to detect the protein expression of nuclear transcription factor (NF)-κB p65, phosphorylation (p)-NF-κB p65, and Toll-like receptor 4 (TLR4) in lung tissue. ResultCompared with the normal group, the white blood cell count in BALF and the levels of TNF-α, IL-1β, IL-6, and MPO in the model group was increased (P<0.01), and the level of SOD was decreased (P<0.05). Pathological damage of lung tissue was obvious, and the protein expression of NF-κB p65, p-NF-κB p65, and TLR4 in lung tissue was increased (P<0.01). Compared with the model group, the white blood cell count in BALF and the levels of TNF-α, IL-1β, IL-6, and MPO in the treatment group was decreased (P<0.05,P<0.01), and the level of SOD was increased (P<0.05,P<0.01). Pathological damage of lung tissue was alleviated, and the protein expression of NF-κB p65, p-NF-κB p65, and TLR4 in lung tissue was decreased (P<0.01). ConclusionZingiberis Rhizoma Recens alcohol extract may play a protective role in LPS-induced acute lung injury in mice by inhibiting the TLR4/NF-κB signaling pathway.
ABSTRACT
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.
ABSTRACT
Ferroptosis is a new type of programmed cell death, characterized by iron overload and lipid peroxidation. Cardiovascular disease (CVD) is an ischemic or hemorrhagic disease of the heart caused by various factors, mainly including myocardial infarction, heart failure, etc. Ferroptosis is involved in the process of myocardial cell damage and plays a driving role in the progression of various CVDs. Its main mechanisms include the destruction of iron homeostasis, the production of reactive oxygen species, the disorder of the antioxidant system, mitochondrial membrane damage, endoplasmic reticulum stress, tumor suppressor gene p53, transcription factor Nrf2 pathway, etc. Myocardial injury is one of the causes of death in many patients with heart disease. Monomers or compounds of traditional Chinese medicine have shown good effects in the treatment of myocardial cell injury caused by ferroptosis, including baicalin protecting cardiac microvascular endothelial cells of myocardial ischemia-reperfusion (I/R) rats through intracellular phosphatidylinositol kinase/phosphokinase B/endothelial nitric oxide synthase (PI3K/Akt/eNOS) pathway, Aralia elata saponin inhibiting myocardial cell ferroptosis through glucocorticoid receptor/p53/solute carrier family 7 members 11 (NR3C1/p53/SLC7A11) pathway, Xinyang tablets improving oxidative stress by regulating phosphorylated serine/threonine protein kinase/stress-activated protein kinase/p53 (MLK3/JNK/p53) signaling pathway. It is of great significance to explore the mechanism of ferroptosis and the protective effect of related traditional Chinese medicine after myocardial cell injury. This article reviews the mechanism of ferroptosis and its relationship with myocardial cells, as well as traditional Chinese medicine monomers and formulas for treating CVDs through the ferroptosis pathway. The article focuses on the pathways and effects of traditional Chinese medicine treatment, so as to provide a reference for the treatment of CVDs with traditional Chinese medicine.
ABSTRACT
ObjectiveTo explore whether the mechanism of Shuangshen Ningxin capsules (SSNX) in alleviating myocardial ischemia-reperfusion injury (MIRI) in rats is related to the regulation of mitochondrial fission and fusion. MethodThis study focused on Sprague Dawley (SD) rats and ligated the left anterior descending branch of the coronary artery to construct a rat model of MIRI. The rats were divided into the sham operation group, model group, SSNX group (90 mg·kg-1) and trimetazidine group (5.4 mg·kg-1). The activity of superoxide dismutase (SOD) and the content of malondialdehyde (MDA) were detected by micro method. Changes in mitochondrial membrane potential (△Ψm) and the degree of mitochondrial permeability transition pore (mPTP) opening were detected by the chemical fluorescence method. The intracellular adenosine triphosphate (ATP) level was detected by the luciferase assay. The messenger ribonucleic acid (mRNA) and protein expression levels of mitochondrial fission and fusion related factors dynamin-related protein 1 (DRP1), mitochondrial fission 1 protein (FIS1), optic atrophy protein 1 (OPA1), mitochondrial outer membrane fusion protein 1 (MFN1), and MFN2 were detected by real-time polymerase chain reaction (real-time PCR) and Western blot. ResultCompared with the sham operation group, the model group showed a decrease in serum SOD activity and an increase in MDA content. The opening level of mPTP, the level of △Ψm and ATP content decreased, the protein expressions of mitochondrial fission factors DRP1 and FIS1 increased, and the protein expressions and mRNA transcription levels of fusion related factors OPA1 and MFN1 decreased. Compared with the model group,SSNX significantly increased serum SOD activity, reduced MDA content, increased intracellular ATP level and △Ψm, reduced the opening level of mPTP, downregulated the protein expressions of mitochondrial fission factors DRP1 and FIS1, and increased the mRNA transcription levels and protein expressions of fusion related factors OPA1 and MFN1. ConclusionSSNX inhibits the expressions of mitochondrial fission factors DRP1 and FIS1, and increases the expressions of fusion related factors OPA1 and MFN1, inhibiting mitochondrial fission and increasing mitochondrial fusion, thereby alleviating MIRI.
ABSTRACT
OBJECTIVE To establish a method for simultaneous determination of atorvastatin (ATV) and its active metabolites 2-hydroxy atorvastatin acid (2-HAT), 4-hydroxy atorvastatin acid (4-HAT) and toxic metabolite atorvastatin lactone (ALT) in rat plasma and apply it for pharmacokinetic study. METHODS LC-MS/MS method was adopted for analysis. The one-step precipitation method was used for processing plasma samples (plasma samples were pretreated by acidification to adjust pH value so as to prevent inversion of configuration), gradient elution was used to analyze the samples, and the analysis time was 5 min. Electrospray positive ionization was adopted, and positive ion scanning was performed in multi-reaction monitoring. The m/z of quantified ion pairs of ATV and its metabolites such as 2-HAT, 4-HAT and ATL, and internal standard pitavastatin were 559.3→ 440.2, 575.2→440.3, 575.0→440.2, 540.9→448.2 and 422.2→290.0, respectively. After conducting a comprehensive methodological investigation of the analytical method, the concentrations of ATV and its metabolites 2-HAT, 4-HAT,and ATL were determined, and the pharmacokinetic parameters of ATV and its metabolites were calculated using the non- compartment model of WinNonlin 6.1. RESULTS The results of methodological validation showed that endogenous substances in blank plasma did not interfere with the determination of the components to be tested, and the standard curve had a good linear relationship; the lower limits of quantification for ATV, 2-HAT, 4-HAT and ATL were 0.5, 0.5, 0.25 and 0.063 nmol/L, respectively. The precision, accuracy, recovery, matrix effect and stability investigation were all in line with the requirements of biological analysis. Pharmacokinetic analysis showed that after intragastric administration in rats, ATV calcium metabolized rapidly, and was mainly exposed to blood circulation in the form of ATV and 2-HAT, with the lowest concentration of lactone-type metabolites. CONCLUSIONS The established method is precise, rapid and accurate for plasma concentration analysis of ATV and its active/toxic metabolites. The application of the method could help to fully elucidate the pharmacokinetic characteristics of atorvastatin calcium in rats.

ABSTRACT
ObjectiveTo screen and establish animal models of combined stasis and toxin syndrome based on the comparison of three modeling methods, i.e., carrageenan (Ca), Ca combined with dried yeast (Ca+Yeast), and Ca combined with lipopolysaccharide (Ca+LPS). MethodForty SPF male SD rats were randomly divided into normal group, Ca group, Ca+Yeast group, and Ca+LPS group, with 10 rats in each group. The Ca group, Ca+Yeast group, and Ca+LPS group received an intraperitoneal injection of Ca (10 mg·kg-1) on the first day. The Ca+LPS group received an intraperitoneal injection of LPS (50 μg·kg-1) on the second day, and the Ca+Yeast group received a subcutaneous injection of dry yeast suspension (2 mg·kg-1) on the back on the second day. The rectal temperature of each group was dynamically observed after modeling. After 24 hours of modeling, the macroscopic evaluation indexes, including tongue manifestation, pulse, and black tail length in each group were observed. The PeriCam PSI imaging system was used to detect the blood flow perfusion of the rat tail. The automatic hemorheology analyzer was used to measure the whole blood viscosity and plasma viscosity of each group. The PL platelet function analyzer was used to detect the platelet aggregation rate of the rats. The enzyme-linked immunosorbent assay (ELISA) was used to detect the interleukin-6 (IL-6) level in the rat plasma. The myocardial tissue, brain tissue, and lung tissue of each group of rats were observed by hematoxylin-eosin (HE) staining. ResultCompared with the normal group, all three model groups showed varying degrees of black tail (P<0.05, P<0.01), reduced blood flow perfusion at the tail end (P<0.05, P<0.01), decreased R, G, and B values of tongue manifestation (P<0.05, P<0.01), and increased maximum platelet aggregation rate (P<0.05, P<0.01). The pulse amplitudes of the Ca+Yeast group and the Ca+LPS group were lower than that of the normal group (P<0.05, P<0.01). In addition, the average rectal temperature of the Ca+Yeast group increased after 24 hours of modeling (P<0.01), and the low-, medium-, and high-shear whole blood viscosity and plasma viscosity increased (P<0.05, P<0.01) as compared with those in the normal group. Additionally, the expression level of the plasma inflammatory factor IL-6 was significantly up-regulated (P<0.05). Pathological morphology results showed that the Ca+Yeast group had the most severe pathological changes, with small foci of myocardial fiber dissolution, inflammatory cell infiltration, and fibroblast proliferation observed. In the hippocampal area, the neurons were sparse and had undergone red degeneration. In the small focus of the lung interstitium, lymphocytes and neutrophils were infiltrated. ConclusionThe animal model of combined stasis and toxin syndrome was properly established using Ca+Yeast. The systematic evaluation system of the model, which includes traditional Chinese medicine four diagnostic information, western medicine microscopic indicators, and tissue pathological morphology, is worthy of consideration and reference by researchers.
ABSTRACT
ObjectiveTo explore the effect of Jiangtang Xiaozhi tablet (JTXZT) on metabolic dysfunction-associated fatty liver disease and to study the mechanism from the perspective of circadian clock-related genes such as circadian locomotor output cycles kaput (CLOCK), brain and muscle aryl hydrocarbon receptor nuclear translocator-like protein 1 (BMAL1), reverse-eritroblastosis receptor (REV-ERB)α and β. MethodA total of 50 male SPF C57BL/6J mice were randomized into normal group (n=10) and modeling group (n=40). The normal group was fed with normal diet, and the modeling group with high-fat diet for 4 weeks. Then the model mice were randomly classified into model group, high-dose (12.5 g·kg-1) and low-dose (6.25 g·kg-1) Jiangtang Xiaozhi tablet groups, and orlistat group (70 mg·kg-1), with 10 mice in each group. The normal group and model group received equivalent volume of distilled water (8 weeks). Then, the body weight of mice was measured, and the content of serum triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) was determined with biochemical method. Serum content of free fatty acid (FFA) and leptin was detected by enzyme-linked immunosorbent assay (ELISA). Pathological changes of liver tissue and epididymal adipose tissue were observed based on hematoxylin-eosin (HE) staining. Liver fibrosis was examined based on Masson's trichrome staining, and changes of lipids based on oil red O staining. The expression of CLOCK, BMAL1, REV-ERBα, and REV-ERBβ was detected by Western blot and immunohistochemistry assay. ResultCompared with the normal group, the model group had high content of TG, TC, LDL-C, HDL-C, AST, ALT, FFA, and leptin (P<0.05, P<0.01), showed ballooning degeneration and focal microvesicular steatosis of liver cells, enlarged adipocytes, and inflammatory cell clusters and fibrous tissue hyperplasia, and displayed increased protein expression of sterol regulatory element binding protein (SREBP) 1 and peroxisome proliferators-activated receptor (PPAR)γ (P<0.01) and decreased protein expression of PPARα (P<0.05), CLOCK, BMAL1, REV-ERBα and β (P<0.05, P<0.01). Compared with the model group, JTXZT-H group down-regulated the content of TG, TC, LDL-C, HDL-C, AST, ALT, FFA, and leptin in mice (P<0.05, P<0.01), and the JTXZT groups demonstrated reduction in the degree and range of ballooning degeneration of liver tissue, alleviation of the compression of hepatic sinusoidal tissue, unobvious inflammatory cell infiltration and fibrous tissue proliferation, reduction in the expression of SREBP1 and PPARγ (P<0.05, P<0.01), and rise of the protein expression of PPARα (P<0.01), CLOCK, BMAL1, REV-ERBα, and REV-ERBβ (P<0.05, P<0.01). ConclusionJTXZT can significantly alleviate the metabolic dysfunction-associated fatty liver disease in mice caused by high-fat diet. The mechanism is the likelihood that it regulates downstream related lipid metabolism proteins (such as SREBP1, PPARγ, and PPARα).
ABSTRACT
ObjectiveTo collect common prescriptions from multiple channels based on the mainstream guidance materials combined with ancient books to provide references for the selection principles of common prescriptions in clinical practice guidelines of traditional Chinese medicine (TCM) and western medicine. MethodWith the research on the selection of commonly used prescriptions in Clinical Practice Guidelines of Chinese and Western Medicine for Cough in Children as an example,the nation-recommended Schedule Ⅲ drugs and prescriptions for cough in children in the clinical diagnosis and treatment guidelines of TCM (TCM and western medicine)/expert consensus/clinical pathway/diagnosis and treatment protocols,three TCM pediatric textbooks, the experience of famous experts, and ancient books were searched for the establishment of a prescription database and analysis of medication regularity. ResultThe results showed that there were 71 commonly used prescriptions for the treatment of cough in children. The top 3 clinically indicated syndromes were the syndrome of phlegm-heat blocking the lung,the syndrome of wind-heat invading the lung,and the syndrome of wind-cold attacking the lung,and the top 5 efficacies corresponding to high-frequency drugs were reliving cough and dyspnea, clearing heat/resolving phlegm, dispersing wind/dissipating cold, clearing heat/purging fire, and dispersing wind/dissipating heat. The most commonly used Chinese medicines included Armeniacae Semen Amarum, Platycodonis Radix, Bolbostemmatis Rhizoma, Ephedrae Herba, Scutellariae Radix, Pinelliae Rhizoma, and Citri Reticulatae Pericarpium. Some drugs showed high internal correlations with Armeniacae Semen Amarum and Platycodonis Radix. There were 228 prescriptions for the treatment of cough in children based on the ancient books in the Chinese Medical Code. The most commonly used Chinese medicines were Pinelliae Rhizoma, Armeniacae Semen Amarum, Ginseng Radix et Rhizoma, Poria, Citri Reticulatae Pericarpium, Platycodonis Radix, Zingiberis Rhizoma Recens, and Bolbostemmatis Rhizoma. The top 5 efficacies corresponding to high-frequency drugs were dispersing wind/dissipating cold, relieving cough and dyspnea, clearing heat/resolving phlegm, warming cold/resolving phlegm, and tonifying Qi. Some drugs showed high internal correlations with Pinelliae Rhizoma and Platycodonis Radix. As revealed by the comparison of ancient and modern medication, the medication principles could be roughly classified into two categories: ventilating the lung/descending Qi and resolving phlegm. In ancient medication, the drugs for cough in children were mainly used for warming, tonifying, dissipating cold, excreting water, alleviating edema, and astringing lung and intestines, while in modern medication, the prescriptions were mainly for dispersing wind, clearing heat, tonifying yin, and moistening dampness. ConclusionThis study systematically analyzed the commonly used prescriptions for the treatment of cough in children and provided references for the selection of TCM in clinical practice guidelines.
ABSTRACT
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.
ABSTRACT
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).

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.
ABSTRACT
ObjectiveTo explore the effect of Jiangtang Xiaozhi tablet (JTXZT) on metabolic dysfunction-associated fatty liver disease and to study the mechanism from the perspective of circadian clock-related genes such as circadian locomotor output cycles kaput (CLOCK), brain and muscle aryl hydrocarbon receptor nuclear translocator-like protein 1 (BMAL1), reverse-eritroblastosis receptor (REV-ERB)α and β. MethodA total of 50 male SPF C57BL/6J mice were randomized into normal group (n=10) and modeling group (n=40). The normal group was fed with normal diet, and the modeling group with high-fat diet for 4 weeks. Then the model mice were randomly classified into model group, high-dose (12.5 g·kg-1) and low-dose (6.25 g·kg-1) Jiangtang Xiaozhi tablet groups, and orlistat group (70 mg·kg-1), with 10 mice in each group. The normal group and model group received equivalent volume of distilled water (8 weeks). Then, the body weight of mice was measured, and the content of serum triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) was determined with biochemical method. Serum content of free fatty acid (FFA) and leptin was detected by enzyme-linked immunosorbent assay (ELISA). Pathological changes of liver tissue and epididymal adipose tissue were observed based on hematoxylin-eosin (HE) staining. Liver fibrosis was examined based on Masson's trichrome staining, and changes of lipids based on oil red O staining. The expression of CLOCK, BMAL1, REV-ERBα, and REV-ERBβ was detected by Western blot and immunohistochemistry assay. ResultCompared with the normal group, the model group had high content of TG, TC, LDL-C, HDL-C, AST, ALT, FFA, and leptin (P<0.05, P<0.01), showed ballooning degeneration and focal microvesicular steatosis of liver cells, enlarged adipocytes, and inflammatory cell clusters and fibrous tissue hyperplasia, and displayed increased protein expression of sterol regulatory element binding protein (SREBP) 1 and peroxisome proliferators-activated receptor (PPAR)γ (P<0.01) and decreased protein expression of PPARα (P<0.05), CLOCK, BMAL1, REV-ERBα and β (P<0.05, P<0.01). Compared with the model group, JTXZT-H group down-regulated the content of TG, TC, LDL-C, HDL-C, AST, ALT, FFA, and leptin in mice (P<0.05, P<0.01), and the JTXZT groups demonstrated reduction in the degree and range of ballooning degeneration of liver tissue, alleviation of the compression of hepatic sinusoidal tissue, unobvious inflammatory cell infiltration and fibrous tissue proliferation, reduction in the expression of SREBP1 and PPARγ (P<0.05, P<0.01), and rise of the protein expression of PPARα (P<0.01), CLOCK, BMAL1, REV-ERBα, and REV-ERBβ (P<0.05, P<0.01). ConclusionJTXZT can significantly alleviate the metabolic dysfunction-associated fatty liver disease in mice caused by high-fat diet. The mechanism is the likelihood that it regulates downstream related lipid metabolism proteins (such as SREBP1, PPARγ, and PPARα).
ABSTRACT
ObjectiveTo collect common prescriptions from multiple channels based on the mainstream guidance materials combined with ancient books to provide references for the selection principles of common prescriptions in clinical practice guidelines of traditional Chinese medicine (TCM) and western medicine. MethodWith the research on the selection of commonly used prescriptions in Clinical Practice Guidelines of Chinese and Western Medicine for Cough in Children as an example,the nation-recommended Schedule Ⅲ drugs and prescriptions for cough in children in the clinical diagnosis and treatment guidelines of TCM (TCM and western medicine)/expert consensus/clinical pathway/diagnosis and treatment protocols,three TCM pediatric textbooks, the experience of famous experts, and ancient books were searched for the establishment of a prescription database and analysis of medication regularity. ResultThe results showed that there were 71 commonly used prescriptions for the treatment of cough in children. The top 3 clinically indicated syndromes were the syndrome of phlegm-heat blocking the lung,the syndrome of wind-heat invading the lung,and the syndrome of wind-cold attacking the lung,and the top 5 efficacies corresponding to high-frequency drugs were reliving cough and dyspnea, clearing heat/resolving phlegm, dispersing wind/dissipating cold, clearing heat/purging fire, and dispersing wind/dissipating heat. The most commonly used Chinese medicines included Armeniacae Semen Amarum, Platycodonis Radix, Bolbostemmatis Rhizoma, Ephedrae Herba, Scutellariae Radix, Pinelliae Rhizoma, and Citri Reticulatae Pericarpium. Some drugs showed high internal correlations with Armeniacae Semen Amarum and Platycodonis Radix. There were 228 prescriptions for the treatment of cough in children based on the ancient books in the Chinese Medical Code. The most commonly used Chinese medicines were Pinelliae Rhizoma, Armeniacae Semen Amarum, Ginseng Radix et Rhizoma, Poria, Citri Reticulatae Pericarpium, Platycodonis Radix, Zingiberis Rhizoma Recens, and Bolbostemmatis Rhizoma. The top 5 efficacies corresponding to high-frequency drugs were dispersing wind/dissipating cold, relieving cough and dyspnea, clearing heat/resolving phlegm, warming cold/resolving phlegm, and tonifying Qi. Some drugs showed high internal correlations with Pinelliae Rhizoma and Platycodonis Radix. As revealed by the comparison of ancient and modern medication, the medication principles could be roughly classified into two categories: ventilating the lung/descending Qi and resolving phlegm. In ancient medication, the drugs for cough in children were mainly used for warming, tonifying, dissipating cold, excreting water, alleviating edema, and astringing lung and intestines, while in modern medication, the prescriptions were mainly for dispersing wind, clearing heat, tonifying yin, and moistening dampness. ConclusionThis study systematically analyzed the commonly used prescriptions for the treatment of cough in children and provided references for the selection of TCM in clinical practice guidelines.
ABSTRACT
Stroke is the leading cause of death and disability. Therefore, it is critical to develop the approaches for improving recovery and neural repair after stroke. Recovery after stroke involves complex interrelated systems of neural repair. The whole process of neural repair requires a series of coordinated interactions, such as response of neuronal cell body to traumatic stimuli, neural stem cell proliferation and migration, axoplasmic transport of signaling molecules, construction of cytoskeleton, and formation of axonal growth cone, to achieve regeneration and growth. As a potential new target for the treatment of neurologic defects, neural remodeling has important research significance in both the specific mechanism of neural repair and the clinical treatment of neurologic defects. After brain injury, single therapy is often ineffective due to the complex mechanism of internal repair, and thus comprehensive therapy becomes the development direction to improve the brain repair. Invigorating qi and promoting blood can promote nerve function remodeling after injury through neural protection, angiogenesis, neurogenesis, loop reconstruction, and cytokine regulation, playing a key role in nerve repair after stroke. Its mechanism is associated with autophagy, immunomodulation, and microRNA regulation, which fully embodies the multi-pathway, multi-target, and overall regulation characteristics of invigorating Qi and activating blood. Therefore, it is of theoretical and guiding significance to study the brain function rehabilitation after stroke by invigorating qi and activating blood.
ABSTRACT
ObjectiveTo explore the effect of Buyang Huanwutang (BYHWT) on platelet function and inflammatory cytokines in the rat model of acute blood stasis. MethodThe model of acute blood stasis was established with SD rats by ice water bath combined with injection of epinephrine. Rats were randomly assigned into four groups: normal group, model group, BYHWT (3.2 g·kg-1) group, and aspirin (60 mg·kg-1) group. The rats were injected with epinephrine hydrochloride on day 8 after 7 days of modeling. The macroscopic indexes of triditional Chinese medicine (TCM) syndrome including tongue manifestation and pulse manifestation were observed, while hemorheological indexes, blood coagulation, and platelet aggregation were detected. The serum levels of the inflammatory cytokine matrix metalloprotein-9 (MMP-9) and the adhesion factor intercellular adhesion molecule-1 (ICAM-1) and were determined by enzyme-linked immunosorbent assay (ELISA). ResultThe pulse distention of rats in the model group was lower than that in the normal group (P<0.01), while BYHWT improved the pulse distention of the rats with the syndrome of blood stasis (P<0.01). In the model group, the tongue showed the characteristics of blood stasis syndrome, with dark purple veins at the tongue bottom and lower values of R, G, B on the tongue surface than those in the normal group (P<0.01), which, however, can be recovered by BYHWT (P<0.01). The blood viscosity at high, medium, and low shear stress and the plasma viscosity in the model group were higher than those in the normal group (P<0.01, P<0.05). Compared with the model group, BYHWT restored the whole blood viscosity under high, medium and low shear stress and plasma viscosity (P<0.05,P<0.01). The model group had shorter prothrombin time (PT), shorter thrombin time (TT), and higher fibrinogen (FIB) than the normal group (P<0.05, P<0.01). BYHWT improved the TT and reduced the FIB in the rats with blood stasis syndrome (P<0.01). The platelet aggregation rate induced by arachidonic acid (AA) and adenosine diphosphate (ADP) in the model group was higher than that in normal group (P<0.01) and BYHWT decreased the platelet aggregation rate of the rats with blood stasis syndrome (P<0.01). The results of scanning electron microscopy showed that the model group exhibited excessive platelet activation, obvious pseudopodia, and increased aggregation of platelets compared with the normal group, while platelet activation and aggregation were rare in the BYHWT group. The serum levels of MMP-9 and ICAM-1 in the model group were higher than those in the normal group (P<0.01), which were decreased in the BYHWT group (P<0.05, P<0.01). ConclusionThe SD rats with the syndrome of acute blood stasis induced by ice water bath combined with injection of epinephrine demonstrate obvious changes in platelet function and morphology, inflammation, and abnormal cell adhesion. In the treatment of acute blood stasis in rats, BYHWT may reduce thrombosis and improve blood consistency and cohesion by mitigating inflammation, down-regulating cell adhesion factor overexpression, and improving platelet shape and function.

The content of type Ⅲ collagen [(6.566±1.620)ng/ml,(7.170±0.470)ng/ml vs. (11.241±2.234)ng/ml] in Ginsenoside Re high, medium group were significantly decreased ( P<0.01). The expression of β-catenin (0.281±0.016, 0.301±0.021 vs. 0.409±0.037) was significantly decreased and the expression of p-GSK-3β (0.369±0.049 vs. 0.268±0.048) in Ginsenoside Re high, medium group were significantly increased ( P<0.01). Conclusion:Ginsenoside Re plays an important role in inhibiting CFs proliferation and reducting the synthesis of collagen and TGF-β 1 by regulating abnormal expression of Wnt/β-catenin signaling pathway. It has the potential to delay the myocardial fibrosis of diabetes mellitus.
ABSTRACT
Objective This study aims to analyze the prevalence, distribution, and risk factors of abnormal glucose metabolism in urban and rural adult hypertension patients in Zhengzhou. Methods The study was conducted on permanent residents aged 18 years and over (with at least 6 months of residence) in urban and rural areas of Zhengzhou. The survey subjects were chosen by the multi‐stage sampling method. Basic information regarding the height, weight, waist circumference, and blood pressure of 6 798 people who met the standards of admission and discharge were obtained through an on‐site questionnaire survey and physical examination. Blood samples were collected and blood glucose and lipid levels were detected. Results There were 1 985 patients with hypertension, with a prevalence rate of 29.20% and the standardized prevalence rate was 26.53%. Blood samples were collected from 1 936 hypertensive patients (55.8±13.6 years), of whom 903 were male (46.64%) and 1 033 female (53.36%). Among 1 050 patients (54.24%) with abnormal glucose metabolism, the impaired fasting glucose rate was 4.44%, the decreased glucose tolerance rate was 22.21%, and the diabetes rate was 27.56%. Blood samples were collected from 4 748 non‐hypertensive patients and 1 123 patients (23.65%) with abnormal glucose metabolism. The prevalence of abnormal glucose metabolism in hypertensive patients was significantly higher than that in non‐hypertensive patients, and the difference was statistically significant (χ2=586.264, P<0.001). The prevalence rate of abnormal glucose metabolism in hypertensive patients was higher in females, 58.57%, than in males, 49.28% (χ2=16.743, P<0.001). Urban patients showed a higher abnormal glucose metabolism, 57.68%, than rural patients did, 51.67% (χ2=6.984, P<0.001), and the prevalence of abnormal glucose metabolism in hypertensive patients showed a significant upward trend with an increase in age. Patients with central obesity, abnormal blood lipids, family diabetes history, non‐smokers, and non‐drinkers showed a higher prevalence of abnormal glucose metabolism, and the differences were statistically significant (P<0.05). The prevalence of abnormal glucose metabolism increased with age and body mass index, and decreased with increase in education level, with differences being statistically significant (P<0.001). Multivariate logistic regression analysis showed that age, obesity, centripetal obesity, dyslipidemia, and family history of diabetes were the main risk factors for abnormal glucose metabolism in patients with hypertension. Conclusions There is a relatively high prevalence of abnormal glucose metabolism in hypertension patients among the urban and rural residents of Zhengzhou. In the management of hypertension, the detection and intervention for reducing abnormal glucose metabolism should be strengthened and related risk factors must be prevented. The age for health management objectives among hypertension and diabetes patients should be further reduced.
