[Clinical experience of Tianxiong Granules in treatment of hypertension based on treatment principle of supressing Yang and promoting blood circulation].

Hypertension is the most common chronic disease in clinics and has become the most common risk factor for cardiovascular diseases. Because of its high incidence rate, disability rate, and mortality, it has attracted worldwide attention. Despite continuous progress in modern medicine in the treatment of hypertension with new antihypertensive drugs such as Zilebesiran, a nucleic acid drug that acts on microRNA, direct renin inhibitors, and renal sympathetic blockade, the control rate is still not ideal. How to effectively prevent and control hypertension has become one of the urgent clinical challenges to be solved. Traditional Chinese medicine(TCM) has a long record of treating hypertension and has accumulated rich experience, including theoretical understanding, effective single medicine, compound medicine, traditional Chinese patent medicines, and classic famous prescriptions. In TCM, hypertension belongs to the categories of diseases such as dizziness and headache. Previous literature and clinical studies have found that hypertension has key pathogenesis such as fire syndrome, fluid syndrome, deficiency syndrome, and blood stasis syndrome. Among them, the hyperactivity of liver Yang is closely related to blood pressure fluctuations, blood pressure variability, inflammation, and sympathetic activity stimulation. Internal obstruction by blood stasis is closely related to the damage of target organs such as the heart, brain, and kidneys in hypertension. Therefore, the two key pathogenesis of liver yang hyperactivity and internal obstruction by blood stasis run through the entire process of hypertension. Previous studies have found that the effective empirical formula Tianxiong Granules, based on the principles of suppressing Yang and promoting blood circulation, originated from the classic formula Xiongqiong Tianma Pills in Yu Yao Yuan Fang. It is composed of Gastrodiae Rhizoma, Chuanxiong Rhizoma, Puerariae Lobatae Radix, Achyranthis Bidentatae Radix, and Cyathulae Radix and has significant therapeutic effects in the treatment of hypertension. The clinical indications include headache, dizziness, bloating, strong neck, and weak waist and legs. At the same time, it may be accompanied by poor speech, thirst, normal or loose stools, soreness in the waist and legs, lower limb pain, muscle and pulse spasm, menstrual and abdominal pain, dark red tongue, strong pulse strings, or straight and long pulse strings that pass through the mouth of an inch. In the combination rule, it can be used according to the different pathogenesis stages of hypertension patients. In the fire syndrome stage, it is often combined with Tianma Gouteng Decoction and Chaihu Jia Longgu Muli Decoction. In the fluid syndrome stage, it is often combined with Banxia Baizhu Tianma Decoction. In the deficiency syndrome stage, it is often combined with Liuwei Dihuang Pills and Shenqi Pills. In terms of dosage, it is important to focus on the main symptoms and adjust the dosage of key drugs based on blood pressure values. Some drugs can be used in sufficient quantities. By analyzing the compatibility of Tianxiong Granules, clinical application indications, combined formula experience, and dosage application experience, we provide effective treatment methods and more options for TCM to treat hypertension with Yang hyperactivity and blood stasis syndrome.

Uric acid-lowering effect of harpagoside and its protective effect against hyperuricemia-induced renal injury in mice.

Hyperuricemia (HUA) is caused by increased synthesis and/or insufficient excretion of uric acid (UA). Long-lasting HUA may lead to a number of diseases including gout and kidney injury. Harpagoside (Harp) is a bioactive compound with potent anti-inflammatory activity from the roots of Scrophularia ningpoensis. Nevertheless, its potential effect on HUA was not reported. The anti-HUA and nephroprotective effects of Harp on HUA mice were assessed by biochemical and histological analysis. The proteins responsible for UA production and transportation were investigated to figure out its anti-HUA mechanism, while proteins related to NF-κB/NLRP3 pathway were evaluated to reveal its nephroprotective mechanism. The safety was evaluated by testing its effect on body weight and organ coefficients. The results showed that Harp significantly reduced the SUA level and protected the kidney against HUA-induced injury but had no negative effect on safety. Mechanistically, Harp significantly reduced UA production by acting as inhibitors of xanthine oxidase (XOD) and adenosine deaminase (ADA) and decreased UA excretion by acting as activators of ABCG2, OAT1 and inhibitors of GLUT9 and URAT1. Moreover, Harp markedly reduced infiltration of inflammatory cells and down-regulated expressions of TNF-α, NF-κB, NLRP3 and IL-1ß in the kidney. Harp was a promising anti-HUA agent.

Helical Nanographenes Bearing Pentagon-Heptagon Pairs by Stepwise Dehydrocyclization.

The incorporation of pentagon-heptagon pairs into helical nanographenes lacks a facile synthetic route, and the impact of these pairs on chiroptical properties remains unclear. In this study, a method for the stepwise construction of pentagon-heptagon pairs in helical nanographenes by the dehydrogenation of [6]helicene units was developed. Three helical nanographenes containing pentagon-heptagon pairs were synthesized and characterized using this approach. A wide variation in the molecular geometries and photophysical properties of these helical nanographenes was observed, with changes in the helical length of these structures and the introduction of the pentagon-heptagon pairs. The embedded pentagon-heptagon pairs reduced the oxidation potential of the synthesized helical nanographenes. The high isomerization energy barriers enabled the chiral resolution of the helicene enantiomers. Chiroptical investigations revealed remarkably enhanced circularly polarized luminescence and luminescence dissymmetry factors with an increasing number of the pentagon-heptagon pairs.

Antifungal mechanism of rose, mustard, and their blended essential oils against Cladosporium allicinum isolated from Xinjiang naan and its storage application.

AIMS: To reveal the inhibition mechanism of rose, mustard, and blended essential oils against Cladosporium allicinum isolated from Xinjiang naan, and investigate the effect of the three essential oils on oxidative damage and energy metabolism. METHODS AND RESULTS: Rose and mustard essential oils significantly inhibited mycelial growth and spore viability in a dose-dependent relationship. After essential oil treatment, the cell membrane permeability was altered, and significant leakage of intracellular proteins and nucleic acids occurred. SEM observations further confirmed the disruption of cell structure. ROS, MDA, and SOD measurements indicated that essential oil treatment induced a redox imbalance in C. allicinum, leading to cell death. As for energy metabolism, essential oil treatment significantly reduced Na+K+-ATPase, Ca2+Mg2+-ATPase, MDH activity, and CA content, impairing metabolic functions. Finally, storage experiments showed that all three essential oils ensured better preservation of naan, with mustard essential oil having the best antifungal effect. CONCLUSIONS: Rose and mustard essential oils and their blends can inhibit C. allicinum at multiple targets and pathways, destroying cell morphological structure and disrupting metabolic processes.

[Interpretation and review of Clinical Practice Guidelines for Management of Hypertension in China (2020 edition) and exploration of traditional Chinese medicine for antihypertensive treatment].

Hypertension is the most important risk factor for cardiovascular disease-related deaths among urban and rural residents, and it has become a significant global public health issue. In October 2022, the Clinical Practice Guidelines for the Management of Hypertension in China(hereinafter referred to as the Practice Guidelines) were jointly released by the National Cardiovascular Center and other academic organizations. The Practice Guidelines sparked extensive discussions as they clearly lowered the diagnostic criteria for hypertension, raised the blood pressure targets for elderly patients, and proposed changes in the timing of early medication intervention. While these adjustments have some international evidence-based support, there is still debate regarding the cardiovascular benefits of intensified blood pressure control based on the existing level of evidence. Furthermore, whether the series of new standards proposed in the Practice Guidelines are suitable for the Chinese population and whether the hypertension control level in primary care in China can adapt to the new diagnostic and treatment standards require further in-depth research. In contrast to the strict blood pressure control concept emphasized in the Practice Guidelines, traditional Chinese medicine(TCM) emphasizes the concept of comprehensive prevention and treatment and holistic therapy in the treatment of hypertension, including prehypertension, hypertension, and target organ damage. In recent years, based on abundant clinical trial research and high-quality evidence-based support, the advantages of TCM in treating hypertension have gradually emerged. Previous studies by this research team have found that the pathogenesis of hypertension includes three major types: fire syndrome, fluid retention syndrome, and deficiency syndrome. TCM treatment of hypertension features stable blood pressure reduction, gentle blood pressure lowering, and long-lasting effects. In addition to blood pressure reduction, it also has effects such as reversing risk factors and protecting target organ damage. It demonstrates the characteristics of multiple targets, multiple components, and comprehensive regulation, and can be applied throughout the entire process of prevention and treatment, including prehypertension, hypertension, and target organ damage in the early, middle, and late stages of hypertension. Therefore, it has certain clinical application prospects.

[Connotation of Shenqi Pills based on severe cases in cardiovascular care unit and modern pathophysiological mechanism and application of Shenqi Pills for heart failure, renal failure, cardiorenal syndrome, and diuretic resistance in critical care medicine].

Shenqi Pills, first recorded in Essentials from the Golden Cabinet(Jin Kui Yao Lue) from ZHANG Zhong-jing in Han dynasty, have the effect of warming and tonifying the kidney Qi and are mainly used for the treatment of insufficiency of kidney Qi and kidney Yang. According to modern medicine, kidney Qi involves heart function, kidney function, immune function, and so on. The clinical indications of Shenqi Pills include kidney deficiency, abnormal fluid, and abnormal urination, and the last one is classified into little urine, much urine, and dysuria. In clinical settings, Shenqi Pills can be applied for the treatment of heart failure, renal failure, cardiorenal syndrome, and diuretic resistance, as well as endocrine, urological, orthopedic, and other chronic degenerative diseases. Shenqi Pills are ideal prescriptions for the weak constitution and emergency treatment. It is of great value and significance to carry out in-depth research on the connotation of the classic articles by integrating TCM and western medicine based on "pathogenesis combined with pathology and drug properties combined with pharmacology".

[Connotation of distal bleeding based on modern pathophysiological mechanism and application of Huangtu Decoction for acute coronary syndrome complicated with acute upper gastrointestinal hemorrhage in critical care medicine].

Huangtu Decoction, first recorded in Essentials from the Golden Cabinet(Jin Kui Yao Lue) from ZHANG Zhong-jing in Han dynasty, is used to treat distal bleeding. It is mainly treated for the syndrome of failing to control blood with spleen-yang deficiency. The connotation of distal bleeding is more extensive, including not only upper gastrointestinal bleeding in the traditional sense such as peptic ulcer bleeding, gastrointestinal tumors, gastric mucosal lesions, vascular dysplasia, esophagogastric variceal bleeding, and pancreatic and biliary tract injury, but also other anorectal diseases such as part colon and rectal cancer swelling or polyps, hemorrhoids, and anal fissure and other parts of bleeding such as epistaxis, thrombocytopenia, functional uterine bleeding, threatened abortion, and unexplained hematuria. Distal bleeding also involves syndromes of failing to keep part deficient and cold fluids in interior, such as nocturia, enuresis, clear nose, sweating, cold tears, and leucorrhea, and excessive gastrointestinal bleeding caused by anti-plate and anticoagulant drugs, unexplained positive in the fecal occult blood test, and other modern clinical new problems. The indications of Huangtu Decoction include not only lower blood, defecation before blood, distant blood, hematemesis, epistaxis, and other diseases in traditional Chinese medicine, but also three types of clinical manifestations including bleeding, deficiency syndrome, and stagnant heat syndrome. In the clinic, Huangtu Decoction can be used to treat acute upper gastrointestinal bleeding, acute coronary syndrome complicated with acute upper gastrointestinal bleeding, bleeding events caused by excessive antiplatelet and anticoagulant drugs, unexplained positive in the fecal occult blood test, gastrointestinal tumor with bleeding, thrombocytopenia, and other acute and critical diseases. The dosage of Cooking Stove Earthkey, Rehmanniae Radix, and Asini Corii Colla in Huangtu Decoction is the key to hemostasis.

[Zhenwu Decoction:connotation interpretation based on severe cases and modern pathophysiological mechanisms and application in treatment of heart failure in critical care unit].

Zhenwu Decoction is recorded in Treatise on Febrile Diseases by an outstanding physician ZHANG Zhong-jing in the Han dynasty. With effect of warming yang, transforming Qi, and promoting urination, Zhenwu Decoction is mainly used to treat edema due to yang deficiency. The studies of the severe and critical cases and the pathophysiological mechanisms have demonstrated that the record of Zhenwu Decoction in Treatise on Febrile Diseases describes the clinical symptoms and therapeutic regimen of acute heart failure. The syndrome treated by this formula may be related to the misdiagnosis and wrong treatment. Due to the difficult distinguishing between cardiogenic dyspnea and pulmonary dyspnea, high doses of Ephedrae Herba may be misused for inducing sweating, which may finally lead to the acute aggravation of heart failure, electrolyte disorder, and pulmonary infection. The syndrome treated by Zhenwu Decoction can illustrate the lack of experience of ancient physicians in treating acute heart failure. The description of "trembling and shivering" may be the clinical manifestation of heart failure, which is an upgraded version of "trembling and shaking" treated by Linggui Zhugan Decoction.(1)In terms of diseases, Zhenwu Decoction is suitable for the treatment of acute or chronic heart failure, cardiorenal syndrome, and diuretic resistance. The decoction is especially suitable for treating whole heart failure, acute heart failure, heart failure with reduced ejection fraction, and heart failure with the syndrome of sold and dampness. In addition, it can be used to treat both type Ⅱ and type Ⅳ cardiorenal syndrome.(2)In terms of symptoms, Zhenwu Decoction can be used for treating chest tightness, palpitations, lower limb edema, difficult urination or increased urine output, fear of cold, pale fat tongue with teeth marks, white and slippery tongue fur, and deep or slow pulse.(3)In terms of the pharmacological mechanism, Zhenwu Decoction treats heart failure following the principle of promoting urination, expanding blood vessels, and invigorating heart in modern medicine. Aconiti Lateralis Radix Praparata is the sovereign herb in the formula, with the recommended dosage of 30-60 g. However, arrhythmia may be caused by high doses of Aconiti Lateralis Radix Praparata, which should be used with concern. In addition to Zhenwu Decoction, Shenqi Pills, Renshen Decoction, Wuling Powder, and Fangji Huangqi Decoction with the effect of invigorating spleen, replenishing Qi, warming Yang, and promoting urination can be used in the recovery stage. The therapy of reinforcing Yang was the last choice for critical cases due to the lack of medical conditions, unclear clinical diagnosis in history, which should be treated objectively now.

[Connotation of Xiao Chaihu Decoction combined with Maxing Shigan Decoction based on severe cases and modern pathophysiological mechanism and application for severe pulmonary infection and acute exacerbation of chronic obstructive pulmonary disease in critical care medicine].

Xiao Chaihu Decoction combined with Maxing Shigan Decoction is a classic herbal formula. All of them are derived from Treatise on Cold Damage(Shang Han Lun) by ZHANG Zhong-jing. This combination has the effects of harmonizing lesser yang, relieving exterior syndrome, clearing lung heat, and relieving panting. It is mainly used for treating the disease involving the triple-Yang combination of diseases and accumulation of pathogenic heat in the lung. Xiao Chaihu Decoction combined with Maxing Shigan Decoction is a classic combination for the treatment of exogenous diseases involving the triple-Yang combination. They are commonly used in exogenous diseases, especially in the north of China. This combination is also the main treatment strategy for coronavirus disease 2019(COVID-19) accompanied by fever and cough. Maxing Shigan Decoction is a classical herbal formula for treating the syndrome of phlegm-heat obstructing the lung. "Dyspnea after sweating" suggests the accumulation of pathogenic heat in the lung. Patients with mild symptoms may develop cough and asthma along with forehead sweating, and those in critical severe may develop whole-body sweating, especially the front chest. Modern medicine believes that the above situation is related to lung infection. "Mild fever" refers to syndromes rather than pathogenesis. It does not mean that the heat syndrome is not heavy, instead, it suggests that severe heat and inflammation have occurred. The indications of Xiao Chaihu Decoction combined with Maxing Shigan Decoction are as follows.(1) In terms of diseases, it is suitable for the treatment of viral pneumonia, bronchopneumonia, lobar pneumonia, mycoplasma pneumonia, COVID-19 infection, measles with pneumonia, severe acute respiratory syndrome(SARS), avian influenza, H1N1 influenza, chronic obstructive pulmonary disease with acute exacerbation, pertussis, and other influenza and pneumonia.(2) In terms of syndromes, it can be used for the syndromes of bitter mouth, dry pharynx, vertigo, loss of appetite, vexation, vomiting, and fullness and discomfort in the chest and hypochondrium. It can also be used to treat alternate attacks of chill and fever and different degrees of fever, as well as chest tightness, cough, asthma, expectoration, dry mouth, wanting cold drinks, feeling agitated, sweating, yellow urine, dry stool, red tongue, yellow or white fur, and floating, smooth, and powerful pulse, especially the right wrist pulse.

[Arrhythmia:innovative understanding from traditional Chinese medicine and treatment by classic herbal formulas].

Arrhythmia, a common and frequently occurring cardiovascular disease, causes a heavy burden on the public health of China. Approximately 20 million patients are suffering from this disease in China and treated by pharmacological and surgical therapies. However, antiarrhythmic drugs can cause arrhythmia and surgical treatment has the risks of failure and recurrence. Therefore, the clinical outcome of arrhythmia remains to be improved. According to the traditional Chinese medicine(TCM) theory, arrhythmia is a disease of palpitation induced by 7 conditions: liver depression and Qi stagnation, accumulation of turbid phlegm, fluid retention attacking the heart, fire-heat disturbing the heart, stasis obstruction of heart vessel, cold congealing in heart vessel, and the deficiency of Qi, blood, Yin, and Yang. Therefore, this study concisely proposed 7 TCM syndromes of arrhythmia, including the palpitation due to depression, phlegm, fluid retention, fire, blood stasis, cold, and deficiency. The corresponding treatment strategies were recommended as follows: Chaihu Longgu Muli Decoction for the palpitation due to depression, Wendan Decoction for the palpitation due to phlegm, Linggui Zhugan Decoction for the palpitation due to fluid retention, Sanhuang Xiexin Decoction for the palpitation due to fire, Xuefu Zhuyu Decoction for the palpitation due to blood stasis, and Mahuang Fuzi Xixin Decoction for the palpitation due to cold, and Guizhi Gancao Decoction, Guizhi Gancao Longgu Muli Decoction, Huanglian Ejiao Decoction, Zhigancao Decoction, and Guipi Decoction for the palpitation due to the deficiency of Qi, blood, Yin, and Yang. Multiple formulas should be combined if the patient presents several TCM syndromes simultaneously. According to the principles of the correspondence between formula and syndrome and the treatment with consideration to both pathogenesis and pathology and both herbal nature and pharmacology, this study proposed an integrated treatment model of "pathogenesis-pathology-nature-pharmacology" to enhance the clinical efficacy of classic herbal formulas in the treatment of arrhythmia.

[Clinical application of Chaihu Jia Longgu Muli Decoction based on modern pathophysiology mechanism].

Chaihu Jia Longgu Muli Decoction was firstly recorded in Treatise on Cold Damage(ZHANG Zhong-jing, Eastern Han dynasty). According to this medical classic, it is originally used in the treatment of the Shaoyang and Yangming syndrome. Based on the modern pathophysiological mechanism, this study interpreted the classic provisions of Chaihu Jia Longgu Muli Decoction. Original records of "chest fullness" "annoyance" "shock" "difficult urination" "delirium" "heavy body and failing to turn over" all have profound pathophysiological basis, involving disorders in cardiovascular, respiratory, nervous, and mental systems. This formula is widely used, which can be applied to treat epilepsy, cerebral arteriosclerosis, cerebral infarction, and other cerebrovascular diseases, hypertension, arrhythmia, and other cardiovascular diseases, insomnia, constipation, anxiety, depression, cardiac neurosis and other acute and chronic diseases as well as diseases in psychosomatic medicine. The clinical indications include Bupleuri Radix-targeted syndrome such as fullness and discomfort in chest and hypochondrium, bitter taste mouth, dry throat, and dizziness, the insomnia, anxiety, depression, susceptibility to fright, upset, dreamfulness and other psychiatric symptoms, red tongue, thick and yellow tongue coating, and wiry hard and powerful pulse. This formula was found to be used in combination with other formulas, such as Gualou Xiebai Decoction, Wendan Decoction, Zhizhu Pills, Juzhijiang Decoction, Suanzaoren Decoction, and Banxia Baizhu Tianma Decoction.

[Research ideas of core formulas-syndromes based on disease-syndrome-treatment combination].

The relationship between disease and syndrome is a research focus in integrated traditional Chinese and western medicine. Depending on the focus, the disease-syndrome combination for treatment is manifested as the different treatment methods for the same disease and the same treatment method for different diseases based on the syndrome, and different treatment methods for the same syndrome and the same treatment method for different syndromes based on the disease. The mainstream model is the combination of di-sease identification in modern medicine with syndrome identification and core pathogenesis in traditional Chinese medicine. However, current research on the combination of disease and syndrome and core pathogenesis tends to focus on the heterogeneity between disease and syndrome and the separation of syndrome and treatment. Therefore, the study proposed the research idea and model of core formulas-syndromes(CFS). According to the theory of formula-syndrome correspondence, the research idea of CFS deepens the research on core pathogenesis, which aims to summarize the core formulas and syndromes for diseases. The research fields include diagnostic criteria for the indications of formulas, distribution patterns of formulas and syndromes for diseases, the evolution of medicinal-syndrome based on formulas-syndromes, formula combination law based on formulas-syndromes, and the dynamic evolution of formulas-syndromes. Through the summary of ancient classics, clinical experience, and medical records, and with the methods of expert consultation, factor analysis, and clustering analysis, research on the diagnostic criteria for the indications of formulas aims to explore the diagnosis information such as the diseases, symptoms, signs, and pathophysiology. The research on the distribution patterns of formulas and syndromes for diseases tends to summarize the specific types of formulas and syndromes for the diseases through literature research and clinical cross-sectional studies based on the establishment of diagnostic criteria for the indications of formulas. The research on the evolution of medicinal-syndrome aims to clarify the medicinal-syndrome law through literature and clinical research. The formula combination law refers to the fact that the core prescriptions for a disease often appear in combination with other prescriptions on a regular basis. The dynamic evolution of formulas-syndromes refers to the continuous transformation and change of formulas and syndromes in the process of disease development with changes in time and space. The CFS is conducive to the unification of disease, syndrome and treatment and to the deepening of the research model of disease and syndrome integration.

[TCM understanding and treatment strategy of hypertension complicated with sexual dysfunction].

Hypertension and its target organ damage have become a major public health problem. Sexual dysfunction is a new problem in the treatment of modern hypertension. Modern pathophysiological studies have shown that hypertension can lead to sexual dysfunction. In addition, three major hypotensive drugs represented by diuretics can also lead to sexual dysfunction. In traditional Chinese medicine(TCM), hypertension belongs to "vertigo" "headache" "head wind", etc. In the past, the understanding of the TCM pathogenesis of hypertension was mainly from the perspectives of "liver wind" and "Yang hyperactivity". However, based on the in-depth research on ancient and modern literature and medical records and many years of clinical practice, it has been identified that kidney deficiency was the key pathogenesis. Hypertension complicated with sexual dysfunction belongs to the category of kidney deficiency syndrome in TCM, especially the deficiency of kidney Yin. Previous studies by other research groups showed that Yin-enriching and kidney-tonifying method could effectively reduce blood pressure, improve sexual dysfunction, reverse risk factors, and protect target organs. This article systematically discussed the TCM understanding, modern pathophysiological mechanism, and the clinical treatment strategy of kidney-tonifying drugs(single drugs and compounds) in the treatment of hypertension complicated with sexual dysfunction in order to provide a scientific basis for kidney-tonifying method in the treatment of hypertension complicated with sexual dysfunction.

Jasminoidin and ursodeoxycholic acid exert synergistic effect against cerebral ischemia-reperfusion injury via Dectin-1-induced NF-κB activation pathway.

BACKGROUND: Jasminoidin (JA) and ursodeoxycholic acid (UA) were shown to act synergistically against ischemic stroke (IS) in our previous studies. PURPOSE: To investigate the holistic synergistic mechanism of JA and UA on cerebral ischemia. METHODS: Middle cerebral artery obstruction reperfusion (MCAO/R) mice were used to evaluate the efficacy of JA, UA, and JA combined with UA (JU) using neurological function testing and infarct volume examination. High-throughput RNA-seq combined with computational prediction and function-integrated analysis was conducted to gain insight into the comprehensive mechanism of synergy. The core mechanism was validated using western blotting. RESULTS: JA and UA synergistically reduced cerebral infarct volume and alleviated neurological deficits and pathological changes in MCAO/R mice. A total of 1437, 396, 1080, and 987 differentially expressed genes were identified in the vehicle, JA, UA, and JU groups, respectively. A strong synergistic effect between JA and UA was predicted using chemical similarity analysis, target profile comparison, and semantic similarity analysis. As the 'long-tail' drugs, the top 20 gene ontology (GO) biological processes of JA, UA, and JU groups primarily reflected inflammatory response and regulation of cytokine production, with specific GO terms of JU revealing enhanced regulation on immune response and tumor necrosis factor superfamily cytokine production. Comparably, the Kyoto Encyclopedia of Genes and Genomes (KEGG) signaling of common targets of JA, UA, and JU focused on extracellular matrix organization and signaling by interleukins, immune system, phagosomes, and lysosomes, which interlock and interweave to produce the synergistic effects of JU. The characteristic signaling pathway identified for JU highlighted the crosstalk between autophagy activation and inflammatory pathways, especially the Dectin-1-induced NF-κB activation pathway, which was validated by in vivo experiments. CONCLUSIONS: JA and UA can synergistically protect cerebral ischemia-reperfusion injury by attenuating Dectin-1-induced NF-κB activation. The strategy integrating high throughput data with computational models enables ever-finer mapping of 'long-tail' drugs to dynamic variations in condition-specific omics to clarify synergistic mechanisms.

Niche Filling Dynamics of Ragweed (Ambrosia artemisiifolia L.) during Global Invasion.

Determining whether the climatic ecological niche of an invasive alien plant is similar to that of the niche occupied by its native population (ecological niche conservatism) is essential for predicting the plant invasion process. Ragweed (Ambrosia artemisiifolia L.) usually poses serious threats to human health, agriculture, and ecosystems within its newly occupied range. We calculated the overlap, stability, unfilling, and expansion of ragweed's climatic ecological niche using principal component analysis and performed ecological niche hypothesis testing. The current and potential distribution of A. artemisiifolia was mapped by ecological niche models to identify areas in China with the highest potential risk of A. artemisiifolia invasion. The high ecological niche stability indicates that A. artemisiifolia is ecologically conservative during the invasion. Ecological niche expansion (expansion = 0.407) occurred only in South America. In addition, the difference between the climatic and native niches of the invasive populations is mainly the result of unpopulated niches. The ecological niche model suggests that southwest China, which has not been invaded by A. artemisiifolia, faces an elevated risk of invasion. Although A. artemisiifolia occupies a climatic niche distinct from native populations, the climatic niche of the invasive population is only a subset of the native niche. The difference in climatic conditions is the main factor leading to the ecological niche expansion of A. artemisiifolia during the invasion. Additionally, human activities play a substantial role in the expansion of A. artemisiifolia. Alterations in the A. artemisiifolia niche would help explain why this species is so invasive in China.

The role of traditional herbal medicine for ischemic stroke: from bench to clinic-A critical review.

BACKGROUND: Ischemic stroke (IS) is a leading cause of death and severe long-term disability worldwide. Over the past few decades, considerable progress has been made in anti-ischemic therapies. However, IS remains a tremendous challenge, with favourable clinical outcomes being generally difficult to achieve from candidate drugs in preclinical phase testing. Traditional herbal medicine (THM) has been used to treat stroke for over 2,000 years in China. In modern times, THM as an alternative and complementary therapy have been prescribed in other Asian countries and have gained increasing attention for their therapeutic effects. These millennia of clinical experience allow THM to be a promising avenue for improving clinical efficacy and accelerating drug discovery. PURPOSE: To summarise the clinical evidence and potential mechanisms of THMs in IS. METHODS: A comprehensive literature search was conducted in seven electronic databases, including PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, the Chinese National Knowledge Infrastructure, the VIP Information Database, the Chinese Biomedical Literature Database, and the Wanfang Database, from inception to 17 June 2022 to examine the efficacy and safety of THM for IS, and to investigate experimental studies regarding potential mechanisms. RESULTS: THM is widely prescribed for IS alone or as adjuvant therapy. In clinical trials, THM is generally administered within 72 h of stroke onset and are continuously prescribed for over 3 months. Compared with Western medicine (WM), THM combined with routine WM can significantly improve neurological function defect scores, promote clinical total effective rate, and accelerate the recovery time of stroke with fewer adverse effects (AEs). These effects can be attributed to multiple mechanisms, mainly anti-inflammation, antioxidative stress, anti-apoptosis, brain blood barrier (BBB) modulation, inhibition of platelet activation and thrombus formation, and promotion of neurogenesis and angiogenesis. CONCLUSIONS: THM may be a promising candidate for IS management to guide clinical applications and as a reference for drug development.

Helical Trilayer Nanographenes with Tunable Interlayer Overlaps.

The synthesis of well-defined nanocarbon multilayers, beyond the bilayer structure, is still a challenging goal. Herein, two trilayer nanographenes were synthesized by covalently linking nanographene layers through helicene bridges. The structural characterization of the trilayer nanographenes revealed a compact trilayer-stacked architecture. The introduction of a furan ring into the helicene linker modulates the interlayer overlap and π-conjugation of the trilayer nanographenes, enabling the tuning of the interlayer coupling, as demonstrated by optical, electrochemical, and theoretical analyses. Both synthesized trilayer nanographenes are rigid chiral nanocarbons and show a chirality transfer from the helicene moiety to the stacked nanographene layers. These helical trilayer nanographenes reported here represent the covalently linked multilayer nanographenes rather than bilayer ones, showing the tunable multilayer stacking structure.

[Review and prospect of traditional Chinese medicine in treatment of hypertension].

Hypertension, a primary cause of cardiovascular and cerebrovascular events, has become a major global public health problem and caused a heavy burden of health economics on the society. In "the 20 Most Important and Most Preventable Health Problems" released by the Chinese Academy of Engineering, hypertension was ranked the second. Due to the disease complexity, many hypertension patients need to take antihypertensive drugs for life. Although significant progress has been achieved in blood pressure lowering by western medicines, the problems including adverse reactions, poor compliance due to long-term medication, and ineffective mitigation in clinical symptoms related to hypertension remain to be addressed. In the last decade, the research on traditional Chinese medicine(TCM) treatment of hypertension has received much attention and achieved remarkable progress. The TCM treatment of hypertension is the most active area of research with integrated Chinese and western medicine in China. In addition to lowering blood pressure smoothly, TCM can alleviate clinical symptoms, reverse risk factors, improve the quality of life, and protect target organs from the damage caused by hypertension. This article systematically reviews the research progress of TCM in treating hypertension in the last decade from the following four aspects: consensus on guideline, clinical trial, experimental study, and systematic review/Meta-analysis. It summarized the evidence of TCM in reducing blood pressure and clarified the mechanism of TCM in reducing blood pressure, aiming to provide a reference for the TCM diagnosis and treatment of hypertension and the development of new drugs.

There were 22 cases of hematuria, 13 cases of pain, 12 cases of bladder spasm and 2 cases of mild fever in group B. There was no significant difference between the two groups.@*CONCLUSION@#Active migration technique is safe and effective in the treatment of 1-2 cm upper ureteral calculi.

Clinical Features and Prognosis of Multiple Myeloma Patients with Secondary Primary Malignancies / 中国实验血液学杂志

OBJECTIVE@#To explore the clinical characteristics and prognosis of multiple myeloma(MM) patients with secondary primary malignancies.@*METHODS@#The clinical data of newly diagnosed MM patients admitted to the First Affiliated Hospital of Zhengzhou University from January 2011 to December 2019 were retrospectively analyzed. The patients with secondary primary malignancies were retrieved, and their clinical features and prognosis were evaluated.@*RESULTS@#A total of 1 935 patients with newly diagnosed MM were admitted in this period, with a median age of 62 (18-94) years old, of which 1 049 cases were hospitalized twice or more. There were eleven cases with secondary primary malignancies (the incidence rate was 1.05%), including three cases of hematological malignancies (2 cases of acute myelomonocytic leukemia and 1 case of acute promyelocytic leukemia) and eight cases of solid tumors (2 cases of lung adenocarcinoma, and 1 case each of endometrial cancer, esophageal squamous cell carcinoma, primary liver cancer, bladder cancer, cervical squamous cell carcinoma, and meningioma). The median age of onset was 57 years old. The median time between diagnosis of secondary primary malignancies and diagnosis of MM was 39.4 months. There were seven cases with primary or secondary plasma cell leukemia, the incidence rate was 0.67%, and the median age of onset was 52 years old. Compared with the randomized control group, the β2-microglobulin level in the secondary primary malignancies group was lower (P=0.028), and more patients were in stage I/II of ISS (P=0.029). Among the 11 patients with secondary primary malignancies, one survived, ten died, and the median survival time was 40 months. The median survival time of MM patients after the secondary primary malignancies was only seven months. All seven patients with primary or secondary plasma cell leukemia died, with a median survival time of 14 months. The median overall survival time of MM patients with secondary primary malignancies was longer than that of the patients with plasma cell leukemia (P=0.027).@*CONCLUSION@#The incidence rate of MM with secondary primary malignancies is 1.05%. MM patients with secondary primary malignancies have poor prognosis and short median survival time, but the median survival time is longer than that of patients with plasma cell leukemia.
