ABSTRACT

Due to a rapidly aging global population, osteoporosis and the associated risk of bone fractures have become a wide-spread public health problem. However, osteoporosis is very heterogeneous, and the existing standard diagnostic measure is not sufficient to accurately identify all patients at risk of osteoporotic fractures and to guide therapy. Here, we constructed the first prospective multi-omics atlas of the largest osteoporosis cohort to date (longitudinal data from 366 participants at three time points), and also implemented an explainable data-intensive analysis framework (DLSF: Deep Latent Space Fusion) for an omnigenic model based on a multi-modal approach that can capture the multi-modal molecular signatures (M3S) as explicit functional representations of hidden genotypes. Accordingly, through DLSF, we identified two subtypes of the osteoporosis population in Chinese individuals with corresponding molecular phenotypes, i.e., clinical intervention relevant subtypes (CISs), in which bone mineral density benefits response to calcium supplements in 2-year follow-up samples. Many snpGenes associated with these molecular phenotypes reveal diverse candidate biological mechanisms underlying osteoporosis, with xQTL preferences of osteoporosis and its subtypes indicating an omnigenic effect on different biological domains. Finally, these two subtypes were found to have different relevance to prior fracture and different fracture risk according to 4-year follow-up data. Thus, in clinical application, M3S could help us further develop improved diagnostic and treatment strategies for osteoporosis and identify a new composite index for fracture prediction, which were remarkably validated in an independent cohort (166 participants).

ABSTRACT

Purpose: We constructed biomimetic nanoparticles with biocompatible, tumor-targeting, laser-responsive properties for ferroptosis-induced colorectal cancer chemo-photothermal therapy, with the aim to realize double-hit ferroptosis treatment for colorectal cancer. Methods: The nanoparticles were prepared by first loading the chemotherapy drug bufotalin (CS-5) with Prussian blue (PB), then combining a hybridized erythrocyte-tumor membrane (M) with PB@CS-5 to produce PB@CS-5@M. The chemo-photothermal therapy efficiency of PB@CS-5@M was tested by in vitro and in vivo experiments. Results and conclusion: The combined PB and CS-5 act as promising ferroptosis inducers to enhance ferroptosis efficacy. The hyperthermia induced by laser stimulation can trigger PB to release CS-5 and iron and ferrous ions, which further promotes ferroptosis.

ABSTRACT

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.

ABSTRACT

The development of cobalt-based supported catalysts with high PMS catalytic activity and stability by adjusting the composition of the support is highly desirable yet remains scarce. In the work, a series of catalysts (Co2AlO4/Al2O3-xSiO2) were prepared by impregnation and high-temperature calcination using Al2O3-xSiO2 with a low Si-Al ratio as the support. Measurement techniques such as XRD, XPS, UV-DRS, FTIR, BET, SEM and HRTEM were used to characterize textural and chemical properties (ratio of Co3+/Co2+, specific surface area, pore size, pore volume, etc.). The ratio of Co3+/Co2+ and pore volume of Co2AlO4/Al2O3-xSiO2 can be turned by controlling the ratio of Si to Al, which are closely related to the catalytic performance and reusability of the catalysts. The optimized catalyst (Co2AlO4/Al2O3-0.25SiO2) can completely degrade 10 mg/L p-nitrophenol (PNP) in 40 min in the pH range of 3-9 with excellent reusability. The effects of several reaction parameters (i.e., PMS dosage, Co2AlO4/Al2O3-0.25SiO2 dosage, reaction temperature, initial pH value, and inorganic ions) on PNP removal were comprehensively investigated. Sulfate radical (SO4•-) and singlet oxygen (1O2) are making a major contribution to the degradation of PNP. Moreover, a millimeter-scale catalyst (CoSiAl-0.25/Al2O3 pellet) was prepared by sol adsorption and high-temperature calcination method, which maintained high oxidation activity after treatment of 18 L wastewater (PNP of 10 mg/L) in a continuous flow process. The method is simple and easy to operate on a large scale, providing a new perspective on the design and preparation of cobalt-aluminum spinel catalysts for activated PMS.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Gastric cancer (GC) is a common gastrointestinal tumor. Gastric precancerous lesions (GPL) are the last pathological stage before normal gastric mucosa transforms into GC. However, preventing the transformation from GPL to GC remains a challenge. Traditional Chinese medicine (TCM) has been used to treat gastric disease for millennia. A series of TCM formulas and active compounds have shown therapeutic effects in both GC and GPL. This article reviews recent progress on the herbal drugs and pharmacological mechanisms of TCM in preventing the transformation from GPL to GC, especially focusing on anti-inflammatory, anti-angiogenesis, proliferation, and apoptosis. This review may provide a meaningful reference for the prevention of the transformation from GPL to GC using TCM.

ABSTRACT

Background: Clinacanthus nutans (Burm.f.) Lindau (C. nutans) has been used in the therapy of hepatitis B (HB) and is effective; however, the mechanism of action has not been elucidated. Objective: To investigate the protective effects of C. nutans aqueous extract on the hepatitis B virus (HBV) mouse model based on correlation analysis between gut microbiota and liver metabolomics. Materials and Methods: We firstly constructed the animal model by high-pressure injection of pcDNA3.1(+)/HBV plasmid into the tail vein and treated it with C. nutans. The biomarkers and inflammatory cytokines of HB were detected by enzyme-linked immunosorbent assay and quantitative PCR; the Illumina-MiSeq platform was used for investigating gut microbiota; the LC-MS/MS method was utilized on screening liver tissue metabolites; multiomics joint analysis was performed using the R program. Results: Compared with the modeling group, C. nutans significantly decreased the expression levels of HBsAg, IL-1ß, TNF-α(P < 0.05) in the serum, and cccDNA (P < 0.05) in the liver tissues of mice. C. nutans dramatically reduced the ratio of Firmicutes and Bacteroidetes (P < 0.05) and significantly declined the proportion of Lactobacillaceae and Lactobacillus(P < 0.05), dramatically increasing the relative abundance of Bacteroidales_S24-7_group, Rikenellaceae, and Alistipes(P < 0.05); LC-MS/MS analysis results showed that C. nutans dramatically upregulate hippuric acid, L-histidine, trehalose, D-threitol, and stachyose and downregulate uridine 5'-diphosphate, cholic acid, trimethylamine N-oxide, CDP-ethanolamine, and phosphorylcholine (P < 0.05). The correlation analysis revealed that C. nutans affects the related metabolite levels of hippuric acid and cholic acid through the modulation of crucial bacteria (Alistipes) (P < 0.01), exerting specific anti-inflammatory effects. Conclusion: These results suggest that C. nutans exerts protective effects in HBV model mice, showing the therapeutic potential for anti-HBV infection.

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.

ABSTRACT

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.

ABSTRACT

A novel composite catalyst prepared by fixing cobalt aluminate (CoAl2O4) spinel on formed alumina carrier by impregnation-calcination route is reported, which can be used to efficiently activate peroxymonosulfate (PMS) to degrade p-nitrophenol (PNP). The internal laws of phase composition and preparation conditions are explored in detail, and the results show that the introduction of additional aluminum ions in the preparation process changes the coordination environment and the electronic state of cobalt ions, which leads to the transformation of spinel/inverted spinel in the composition, and further affects the activity and stability of the catalyst. The selected CoAl-Aaps-600 catalyst has high CoAl2O4 content, showing good cycle performance and low cobalt leaching, and has great catalytic degradation performance at different temperatures and a wide pH range. Most notably, a fixed bed reactor packed with 20 g of CoAl-Aaps-600 exhibits excellent capacity to continuously treat 60 L of PNP solution with acceptable PNP removal ratio and low cobalt leaching content. Sulfate radical and singlet oxygen are identified as the main reactive oxygen species produced in CoAl-Aaps-600/PMS system, and the reaction mechanism is reasonably inferred. This work provides a potential application material and process for the treatment of continuous organic wastewater.

ABSTRACT

Second near-infrared (NIR-II) window type-I photosensitizers have intrinsic advantages in photodynamic/photothermal therapy (PDT/PTT) of some malignant tumors with deep infiltration, large size, complicated location, and low possibility of surgery/radiotherapy. Herein, three chalcogen-element-based donor-acceptor-type semiconducting polymers (poly[2,2″-((E)-4,4″-bis(2-octyldodecyl)-[6,6″-bithieno[3,2-b]pyrrolylidene]-5,5″(4H,4″H)-dione)-alt-2,5-(thiophene)] (PTS), poly[2,2″-((E)-4,4″-bis(2-octyldodecyl)-[6,6″-bithieno[3,2-b]pyrrolylidene]-5,5″(4H,4″H)-dione)-alt-2,5-(selenophene)] (PTSe), and poly[2,2″-((E)-4,4″-bis(2-octyldodecyl)-[6,6″-bithieno[3,2-b]pyrrolylidene]-5,5″(4H,4'H)-dione)-alt-2,5-(tellurophene)] (PTTe)) are synthesized and fully characterized, demonstrating strong absorption in the NIR-II region. Upon adjusting the chalcogen elements, the intramolecular charge-transfer characteristics and the heavy-atom effect are tuned to enhance the intersystem crossing rate, improving the photodynamic effect. Moreover, the energy levels and Gibbs free energies are tuned to facilitate the type-I photodynamic process. As a result, PTTe nanoparticles (NPs) produce superoxide anion radicals (O2 •- ) more efficiently and demonstrate higher photothermal conversion efficiency than PTS and PTSe NPs upon NIR-II (1064 nm) laser irradiation, exhibiting unprecedented NIR-II type-I PDT/PTT performance in vitro and in vivo. This work provides ideas for achieving high-performance NIR-II type-I PDT/PTT semiconducting polymers for hypoxic oncotherapy.
