Exploring Modern Mechanism of Treating Diabetic Retinopathy and Coronary Heart Disease from Perspective of Blood Stasis Under Viewpoint of Treating Different Diseases with the Same Method / 中国实验方剂学杂志

Diabetic retinopathy（DR） and coronary heart disease（CHD） are both major chronic vascular complications that seriously jeopardize the health of the population and often occur together in clinical practice， it is of great clinical value to actively explore the association between the two in the process of disease development and methods of prevention and treatment of modern medicine and traditional Chinese medicine（TCM）. According to TCM， the heart and eyes physiologically communicate with each other by taking Qi， blood and veins as bridges， blood stasis obstructing collaterals is the common TCM etiology of DR and CHD， whose mechanism involves inflammation， oxidative stress and endothelial dysfunction. Promoting blood circulation and removing blood stasis plays an important role in the same treatment for different diseases and prevention and treatment of comorbidities， possibly by inhibiting the expression of interleukin-1β（IL-1β）， endothelin-1（ET-1） and hypoxia inducible factor-1α/vascular endothelial growth factor（HIF-1α/VEGF）， regulating phosphatidylinositol 3-kinases/protein kinase B/mammalian target of rapamycin（PI3K/Akt/mTOR） pathway， initiating adenosine monophosphate（AMP）-activated protein kinase/silent information regulator 1（AMPK/SIRT1） and nuclear transcription factor erythroid 2-related factor 2/heme oxygenase-1（Nrf2/HO-1） signaling pathways， inhibiting Hippo/Yes-associated protein（Hippo/YAP） signaling pathway， inhibiting mitochondrial permeability transition pore and anti-platelet agglutination for treating DR and CHD， which provides a multi-component， multi-pathway and multi-target selection strategies and ideas for the prevention and treatment of DR and CHD by TCM from a biological perspective. Based on this， subsequent studies should focus on constructing clinically relevant comorbidity models， conducting multicenter prospective studies， and fully utilizing artificial intelligence technology to gain a deeper understanding of the relationship between the two diseases， so as to elucidate the mechanism of promoting blood circulation and removing blood stasis in preventing and treating panvascular diseases.

Cardiac output and the pharmacology of general anesthetics: a narrative review

The relationship between cardiac output and anesthetic drugs is important to anesthesiologists, since cardiac output determines the speed with which a drug infused into the bloodstream reaches its target and the intensity of the drug's effect. But rather than focus on how anesthetic drugs affect cardiac output, this narrative review focuses on how changes in cardiac output affect the pharmacokinetics and pharmacodynamics of general anesthetics during the three phases of anesthesia. At induction, an increase in cardiac output shortens both the onset time of propofol for hypnosis and the neuromuscular blocking effect of rapid-acting neuromuscular blockers, favoring the conditions for rapid sequence intubation. During maintenance, changes in cardiac output are followed by opposite changes in the drug plasma concentration of anesthetic drugs. Thus, an increase in cardiac output followed by a decrease in the plasma concentration of the anesthetic could expose the patient to a real risk of intraoperative awakening, which can be avoided by increasing the dose of hypnotic drugs. At emergence, an increase in cardiac output secondary to an increase in pC02 allows for a more rapid recovery from anesthesia. The pC02 can be increased by adding CO2 to the respiratory circuit, lowering the ventilatory rate, or placing the patient on partial rebreathing. Finally, the reversal action of sugammadex for rocuronium-induced neuromuscular block can be shortened by increasing the cardiac output.

La relación entre el gasto cardíaco y los fármacos anestésicos es importante para los anestesiólogos puesto que el gasto cardíaco determina la velocidad con la cual un medicamento que se infunde al torrente sanguíneo llega a su diana y la intensidad del efecto del agente. Pero en lugar de concentrarnos en cómo los fármacos anestésicos afectan el gasto cardíaco, esta revisión narrativa se enfoca en cómo los cambios en el gasto cardíaco afectan la farmacocinética y la farmacodinámica de los agentes anestésicos generales durante las tres fases de la anestesia. En el momento de la inducción, un incremento en el gasto cardíaco acorta tanto el tiempo de inicio del efecto del propofol para la hipnosis como el efecto del bloqueo neuromuscular causado por los bloqueadores neuromusculares de acción rápida, favoreciendo las condiciones para la intubación de secuencia rápida. Durante la fase de mantenimiento, los cambios en el gasto cardíaco vienen seguidos de cambios opuestos en la concentración plasmática del medicamento de los agentes anestésicos. Por lo tanto, un aumento del gasto cardíaco, seguido de una reducción en la concentración plasmática del anestésico, podría exponer al paciente a un riesgo real de despertar intraoperatorio, lo cual puede evitarse aumentando la dosis de los fármacos hipnóticos. En la educción, un aumento en el gasto cardíaco secundario al incremento en el pCO2 permite una recuperación más rápida de la anestesia. El pCO2 puede aumentar agregando CO2 al circuito de la respiración, reduciendo la tasa ventilatoria, o colocando al paciente en re-inhalación parcial. Finalmente, la acción de reversión de sugammadex en caso de bloqueo neuromuscular inducido por rocuronio, puede acortarse aumentando el gasto cardíaco.

Conclusion:The methods of activating blood and removing blood stasis, invigorating the spleen and soothing the liver can reverse the precancerous lesions of patients with gastric collateral stasis syndrome of chronic atrophic gastritis and have a good prognosis.

Pharmacodynamic Material Basis of Astragali Radix and Angelicae Sinensis Radix Drug Pair in Supplementing Qi and Activating Blood Circulation / 中国实验方剂学杂志

ObjectiveTo evaluate the effect of Astragali Radix （AR）-Angelicae Sinensis Radix （ASR） drug pair on supplementing Qi and activating blood circulation in rats with Qi deficiency and blood stasis and provide a theoretical basis for clinical rational medication and identification and quality control of compound pharmacodynamic substances from the three aspects of characteristic map， identification of pharmacodynamic substances， and comparison of blood components. MethodHigh-performance liquid chromatography （HPLC） was employed to establish the fingerprint of AR∶ASR （3∶1）， and ultra-high performance liquid chromatography-Q-Exactive Orbitrap-mass spectrometry （UPLC-Q-Exactive Orbitrap-MS） was employed to analyze the ingredients of the decoction. Adult male Wistar rats with SPF grades were selected and randomly divided into a blank group， a model group， a 3∶1 group， and a 5∶1 group. The rat model of Qi deficiency and blood stasis syndrome was prepared by controlling food intake and swimming in cold water every day. In parallel， each group was given medicine （or water） once a day. The dose of drug groups was 10.2 g∙kg-1， and the model group and blank group were given the same amount of distilled water for 15 d. Animal behavior， body weight， whole blood and plasma viscosity， thymus index， spleen index， the levels of adenosine triphosphate （ATP）， adenosine diphosphate（ADP）， von willebrand factor （vWF）， and ATP/ADP value in serum of rats were recorded. The morphology of vascular endothelium was observed by hematoxylin-eosin （HE） staining and scanning electron microscopy. UPLC-Q-Exactive Orbitrap-MS was used to analyze prototype and metabolic components in serum. ResultThe fingerprint of AR-ASR drug pair （AR-ASR 3∶1） was established. UPLC-Q-Exactive Orbitrap MS identified 49 chemical components in vitro and preliminarily identified 11 prototype components absorbed into blood in vivo. As compared with the blank group， the body mass decreased significantly （P<0.01）， the whole blood （high shear， middle shear， and low shear） viscosity and plasma viscosity were significantly increased （P<0.05， P<0.01）， the thymus index and spleen index decreased significantly （P<0.05， P<0.01）， serum ATP content decreased significantly （P<0.01）， ADP content increased significantly （P<0.01）， ATP/ADP value decreased significantly （P<0.01）， and vWF content increased significantly （P<0.01）. The results of HE staining and scanning electron microscopy showed that the vessels were partially damaged， showing the structural disorder of the intima， the bulge， defect， and roughness of the endothelium， and the obvious cell adhesion and migration in the model group. As compared with the model group， the body mass also increased significantly （P<0.01）. The results of whole blood and plasma viscosity showed that the whole blood low shear viscosity was significantly decreased in the 3∶1 group （P<0.05）. The results of thymus index and spleen index showed that 5∶1 group significantly increased the thymus index of rats （P<0.05）. The results of serum ATP and ADP levels showed that the 5∶1 group had more significant effects on ATP and ADP levels （P<0.05）， and both groups significantly reduced ATP/ADP values （P<0.01）. The results of serum vWF level showed that the vWF content in the 3∶1 group decreased significantly （P<0.05）. The results of HE staining and scanning electronic microscopy showed that the damage of vascular endothelium was improved in the treatment group and the structure of intima was neat. ConclusionAR-ASR drug pair can improve the macro and micro indexes of rats with qi deficiency and blood stasis in the 3∶1 and 5∶1 groups. Overall， the 5∶1 ratio has a better effect on supplementing Qi but 3∶1 ratio has a better effect on promoting blood circulation.

Research progress on using traditional Chinese medicine and extracts for activating blood circulation in prevention and treatment of silicosis / 中国职业医学

Occupational silicosis features as irreversible pulmonary fibrosis, which is caused by long-term inhalation of free silica dust. The pathogenesis of silicosis is complex and there is no cure at present. Traditional Chinese medicine classifies silicosis fibrosis into the category of diseases as "pulmonary paralysis" and "pulmonary arthralgia", and its treatment is based on promoting blood circulation and activating qi. Traditional Chinese medicine for activating blood circulation is one of the commonly used medications, which has the effects of anti-oxidation, anti-inflammation, anti-fibrosis and immunomodulation, and has broad application prospect in the prevention and treatment of silicosis. At present, animal experiments and clinical studies have been carried out using the single Chinese herbs extracts that could activate blood circulation such as Salvia miltiorrhiza, Ligusticum chuanxiong Hort., Panax notoginseng, Curcuma longa L., peach kernel and Carthamus tinctorius L. as well as their compound herbs for the prevention and treatment of silicosis. The mechanisms of anti-pulmonary fibrosis and the efficacy and safety of treating silicosis and its complications were explored. There are also scholars studying Salvia miltiorrhiza, Curcuma longa L. and Danhong injection, Taohong Siwu Decoction and others for prevention and treatment of pulmonary fibrosis. Additionally, network pharmacological research, analyzing potential targets and pathways, were carried out to provide scientific rationale for prevention and treatment of silicosis. However, the effectiveness of research is still uncertain, and it cannot meet the clinical needs. In the future, it is necessary to explore the application of more high-quality active components of traditional Chinese medicine monomer or mixture of activating blood circulation in the prevention and treatment of silicosis, to provide new ideas and scientific basis for the prevention and treatment of silicosis using traditional Chinese medicine.

Differences in Protective Effect of Five Formulas for Promoting Blood Circulation and Removing Blood Stasis on Endothelial Cells of New Zealand Rabbits with Heart Blood Stasis Syndrome Through JNK Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo explore the differences in the protective effects of five formulas for promoting blood circulation and removing blood stasis on the aortic endothelial cells of New Zealand rabbits with heart blood stasis syndrome. MethodEighty New Zealand rabbits were randomly divided into a normal group （n=10） and an experimental group （n=70）. The heart blood stasis syndrome model was induced by starvation combined with a high-fat diet and adrenaline in the rabbits of the experimental group. Subsequently， the model rabbits were randomly divided into a model group， a Xuefu Zhuyutang group （3.55 g·kg-1·d-1）， a Taohong Siwutang group （2.66 g·kg-1·d-1）， a Danshenyin group （1.962 g·kg-1·d-1）， a Huoluo Xiaolingdan group （2.80 g·kg-1·d-1）， a Shixiaosan group （0.56 g·kg-1·d-1）， and a c-Jun N-terminal kinase （JNK） inhibitor （SP600125， 5 μg·kg-1）group. The normal group and the model group received the same amount of distilled water. The rabbits in five Chinese medicine groups were treated correspondingly by gavage， and those in the SP600125 group were injected with 0.5 mL of SP600125-dimethyl sulfoxide diluent. After the treatment， the aorta was collected， and terminal deoxynucleotidyl transferase dUTP nick end labeling （TUNEL） assay was used to detect the apoptosis of aortic endothelial cells. The enzyme-linked immunosorbent assay （ELISA） was used to detect serum levels of tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6）. Western blot was used to detect the protein expression of JNK， phosphorylated JNK （p-JNK）， B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， cysteinyl aspartate-specific protease-9 （Caspase-9）， and cysteinyl aspartate-specific protease-3 （Caspase-3） in aortic tissues. Real-time fluorescence-based quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA levels of JNK， Bcl-2， Bax， Caspase-9， and Caspase-3 in aortic tissues. ResultFive formulas could improve the apoptosis of aortic endothelial cells to varying degrees. To be specific， Xuefu Zhuyutang and Taohong Siwutang were optimal in efficacy， followed by Huoluo Xiaolingdan， Shixiaosan， and Danshenyin， and SP600125 was the worst （P<0.05， P<0.01）. Five formulas could reduce the content of TNF-α and IL-6 （P<0.05， P<0.01）， down-regulate the protein expression levels of JNK， p-JNK， Bax， Caspase-9， and Caspase-3 （P<0.05， P<0.01）， decrease the mRNA expression levels of JNK， Bax， Caspase-9， and Caspase-3 （P<0.05， P<0.01）， and up-regulate the protein and mRNA expression levels of Bcl-2 （P<0.05， P<0.01）. ConclusionFive formulas can all reduce the apoptosis of aortic endothelial cells in New Zealand rabbits with heart blood stasis syndrome with different efficacies. It may be related to the different effects of five formulas on the JNK signaling pathway.

Stasis Caused by Depression and Coronary Heart Disease / 中国实验方剂学杂志

Anxiety and depression are common comorbidities of coronary heart disease and are considered as independent risk factors in addition to traditional cardiovascular risk factors. Anxiety，depression and other mental abnormalities belong to the category of "depressive syndrome" of traditional Chinese medicine，which can lead to stasis of blood due to the lack of Qi flow. "Blood stasis" involves abnormal blood rheology， vascular endothelial dysfunction， chronic inflammatory response， abnormal lipid metabolism and other comprehensive pathological changes， and is the core pathogenesis of coronary heart disease in traditional Chinese medicine. "Depressive syndrome"can aggravate the development of coronary heart disease by promoting blood stasis in multiple ways. Prescriptions and herbs of promoting blood circulation and removing blood stasis can have a clinical effect by promoting blood circulation （improving physiological functions） and removing blood stasis （eliminating pathological changes）. In clinical practice， strengthening the screening of the mental and psychological status of patients with coronary heart disease and providing early and effective psychological interventions and combined Chinese and Western medicine drug treatment can significantly improve the clinical symptoms and prognosis of patients. This article was the first to put forward the academic view of "stasis caused by depression" for the first time，and discuss the modern biological research progress of "depression" in Chinese medicine that promotes blood stasis and aggravates coronary heart disease，in order to provide a basis for the subsequent development of Chinese medicine in the prevention and treatment of coronary heart disease. The aim is to provide a theoretical basis for the subsequent systematic research on the prevention and treatment of coronary heart disease with emotional abnormalities in Chinese medicine.

Effect of Taohong Siwu Decoction() early intervention on mesenchymal stem cells homing in fracture healing in rats / 中国骨伤

OBJECTIVE@#To observe the effects of Taohong Siwu Decoction(, THSWD) on the mesenchymal stem cells(MSCs) migration, homing number and cytokine expression in callus during the early process of fracture healing, and to explore the mechanism of THSWD on accelerationg fracture healing by regulating the homing of MSCs in rats.@*METHODS@#A rat model of right femoral shaft open fracture was established. Thirty-two 5-week-old male Sprague-Dawley rats, weighting 110 to 130 g, were divided into control group, low-dose group, medium-dose group and high-dose group by using random number table. Distilled water was given to the control group, and the other groups were given Taohong Siwu Decoction. The rats were gavaged twice a day for 5 consecutive days after surgery. Bone volume/tissue volume(BV/TV) and bone mineral density(BMD) were observed using micro-computed tomography (micro-CT) at 21 days after surgery. At 5 days post-fracture, peripheral blood MSCs from THSWD treated and untreated rats were cultured in vitro. Subsequently, the migration ability of MSCs was observed by cell migration assay. The number of MSCs homing to the callus at the early stage of fracture (5 d) was detected by Immunohistochemistry (IHC). Protein chip was used to detect the expression of cytokines in callus.@*RESULTS@#Micro-CT results showed that BV/TV was higher in the high-dose group than in the medium-dose group (P=0.032), and higher in the medium-dose group than in the low-dose group(P=0.041), with no difference between the control and low-dose group (P=0.651). In addition, there was no difference in BMD between low-dose group and the model group (P=0.671), and lower in the low-dose group than in the medium-dose group(P=0.018), and the medium-dose group was lower than the high-dose group(P=0.008). Cell migration assay showed that THSWD promotes enhanced the migration ability of peripheral blood MSCs. IHC assay revealed that CD45-, CD90+, CD29+ MSCs significantly increased in bone callus after THSWD intervention compared with the control group. Protein chip showed that THSWD promoted the upregulation of CINC-1(×2.91), CINC-3(×1.59), LIX(×1.5), Thymus Chemokine (×2.55), VEGF (×1.22) and the down-regulation of TIMP-1 (×2.98).@*CONCLUSION@#THSWD, a representative formula of "promoting blood circulation and removing blood stasis", can significantly accelerate fracture healing, and its mechanism may be related to enhancing the migration ability of peripheral blood MSCs and up-regulating CINC-1, CINC-3, LIX, Thymus Chemokine, VEGF and down-regulating TIMP-1 in bone callus, which promotes the peripheral blood MSCs homing in the early stage of fracture.

Protective effect of Qilong Capsules(QL) on the myocardial fibrosis and blood circulation of rats with coronary heart disease of Qi deficiency and blood stasis type was investigated. Sleep deprivation and coronary artery ligation were used to construct a disease-symptom combination model, and 60 SD rats were divided into sham operation(sham) group, syndrome(S) group, disease and syndrome(M) group and QL group randomly. The treatment group received administration of QL 0.4 g·kg~(-1)·d~(-1). Other groups were given the same amount of normal saline. The disease indexes of each group [left ventricular end diastolic diameter(LVESD), left ventricular end systolic diameter(LVEDD), left ventricular ejection fraction(LVEF), left ventricular axis shortening rate(LVFS), myocardial histopathology, platelet morphology, peripheral blood flow] and syndrome indexes(tongue color, pulse, grip power) were detected. In sham group, cardiomyocytes and myocardial fibers were arranged neatly and densely with clear structures. The tongues' color in sham were light red, and the pulse shape were regular. RGB is a parameter reflected the brightness of the image of the tongue. In the S group, the amplitude and frequency of the animal's pulse increased accompanied by decreasing R,G,B, however, the decreased R,G,B was accompanied by reduced pulse amplitude in M group. And in M group, we observed fuzzy cell morphology, hypertrophied myocytes, disordered arrangement of cardiomyocytes and myocardial fibers, reduced peripheral blood flow and increased collagen volume fraction(CVF). Increased LVESD and LVEDD, and decreased LVEF and LVFS represented cardiac function in S group was significantly lower than that in sham. In QL group, the tongue's color was red and the pulse was smooth. The myocardial fibers of the QL group were arranged neatly and secreted less collagen. It improved the blood circulation in the sole and tail, and reversed the increasing of LVEDD, LVESD and the decreasing of LVEF and LVFS of M group. Platelets in M and S group showed high reactivity, and QL could decrease aggregation risk. In conclusion, Qilong Capsules has an obvious myocardial protective effect on ischemic cardiomyopathy, which may inhibit the degree of myocardial fibrosis and reduce platelet reactivity.

Experimental Research Progress of Replenishing Qi and Activating Blood Circulation Traditional Chinese Medicine on Mitochondrial Quality Control in Treatment of Chronic Heart Failure / 中国实验方剂学杂志

Heart failure is a complex clinical syndrome，which is the final result of compensatory failure of heart injury caused by various reasons. Long-term persistent cardiac stress leads to mitochondrial dysfunction，which in turn further damages cardiomyocytes and leads to disease progression. Timely removal of damaged mitochondria in cardiomyocytes and maintaining a good living environment of viable mitochondria is not only an effective means to protect cardiomyocytes，but also a new way to prevent and treat heart failure and ventricular remodeling. Mitochondrial quality control is a series of cellular activities for mitochondria to maintain their structural and functional stability，including oxidative stress response，regulation of mitochondrial dynamics，mitochondrial autophagy，intracellular calcium regulation and so on. Traditional Chinese medicine（TCM） mostly uses drugs of replenishing Qi and activating blood circulation in the treatment of chronic heart failure，and Qi and mitochondria are similar in function. According to TCM，the performance of the body as "static，descending and inhibitory" in the case of Qi deficiency can also be compared with the energy defect of mitochondria. The classical method of tonifying qi and activating blood circulation in TCM can be applied here. In recent years，TCM takes mitochondria as the target and carries out many related experimental studies from the point of view of myocardial energy supply. It is found that Chinese herbs for replenishing Qi and activating blood circulation can participate in regulating the quality control mechanism of intracellular mitochondria with multiple targets and links. It is proved by experiments that Chinese herbs for replenishing Qi and activating blood circulation can exert myocardial protective effect through this mechanism.
