Topology and Semantic Information Fusion Classification Network Based on Hyperspectral Images of Chinese Herbs

Most methods for classifying hyperspectral data only consider the local spatial relation-ship among samples,ignoring the important non-local topological relationship.However,the non-local topological relationship is better at representing the structure of hyperspectral data.This paper proposes a deep learning model called Topology and semantic information fusion classification network(TSFnet)that incorporates a topology structure and semantic information transmis-sion network to accurately classify traditional Chinese medicine in hyperspectral images.TSFnet uses a convolutional neural network(CNN)to extract features and a graph convolution network(GCN)to capture potential topological relationships among different types of Chinese herbal medicines.The results show that TSFnet outperforms other state-of-the-art deep learning classification algorithms in two different scenarios of herbal medicine datasets.Additionally,the proposed TSFnet model is lightweight and can be easily deployed for mobile herbal medicine classification.

Cell-Based Biological Markers for Blood-Enriching Chinese Herbs: Erythropoietin Production in HepG2 Cells and Nitric Oxide Release in Human Umbilical Vein Endothelial Cells (HUVECs)

Chinese tonifying herbs, which are classified into four functional categories (namely, Yang, Qi, Yin, Blood) are commonly used for restoring normal body function and the prevention of diseases. To explore cell-based biological markers for Blood-enriching Chinese herbs, we investigate the effect of 11 commonly used Blood-enriching herbs on erythropoietin (EPO) production in HepG2 cells. Herbs for nourishing Yin were tested for determining the specificity of Blood-enriching herbs in inducing EPO production. In addition, the effects of Blood-enriching herbs on nitric oxide (NO) production in both HepG2 cells and human umbilical vein endothelial cells (HUVECs) were also investigated. The results indicated that methanolic extracts of Blood-enriching herbs (but not Yin-nourishing herbs) showed characteristic pharmacological activity in inducing EPO production in HepG2 cells and NO release in HUVECs. The experimental findings, therefore, support the use of cell-based EPO production and NO release as biological markers for Blood-enriching Chinese tonifying herbs.

Herbs and management of hypertension:Claims,criticism,and challenges

Hypertension(HTN)is one of the most common chronic diseases affecting over 30%of the adult population globally,with a growing incidence rate.This article aims to identify the commonly used herbs for HTN treatment and examine their claims,criticisms,and challenges.It further aims to provide useful recommendations regarding the use of herbs for HTN treatment.HTN complications,such as coronary heart disease,stroke,peripheral vascular disease,vision impairment,and renal failure can result in morbidity and mortality.The high cost of conventional medications,which sometimes may not even be available or easily accessible with their unfavorable side effects as well as taking more than one pill per day,has led hypertensive patients,particularly those in rural areas,to explore alternative treatments such as herbal therapies.It is crucial to determine the different modes of action,doses,safety,and efficacy of herbal remedies used in combination with conventional medications to improve treatment adherence and enhance patient outcomes.

Advances in treatment of ulcerative colitis with herbs: From bench to bedside

Ulcerative colitis(UC), an idiopathic inflammatory disorder in the colon, has become a clinical challenge, owing to the increasing incidence and poor prognosis. The conventional treatments for UC including aminosalicylates, corticosteroids, and immunosuppressants, induce remission in only half of patients. Meanwhile, the treatments often come with serious side effects which can be life-threatening. Herbal medicine, one of the most common traditional Chinese medicine modalities, has been introduced for centuries into clinical treatment of many human diseases such as infections and functional disorders. Recently, the potential effectiveness of herbs has been suggested as the treatment of UC, as shown by a variety of clinical trials and experimental studies. The herbs reported in the literature include aloe vera gel, butyrate, tormentil extracts, wheat grass juice, and curcumin. In the review, bioactivity of the herbs and their involvement in UC treatment are discussed.

Essential oils and functional herbs for healthy aging

As total life expectancy increases, the prevalence of age-related diseases such as diabetes and Alzheimer's disease is also increasing. Many hypotheses about Alzheimer's disease have been developed, including cholinergic neuron damage, oxidative stress, and inflammation. Acetylcholine is a major neurotransmitter in the brain and cholinergic deficits leads to cognitive dysfunction and decline. Recent studies have linked diabetes as a risk factor in developing Alzheimer's disease and other types of dementia. The incidence of patients with type II diabetes and increased levels and activity of α-amylase is higher in patients with dementia. It has been shown that aromatherapy with essential oils from the mint family can improve cognitive performance in Alzheimer's disease patients. Selected monoterpenoids from these essential oils are reported to inhibit acetylcholinesterase, both in vitro and in vivo. Terpenoids are small, fat-soluble organic molecules that can transfer across nasal mucosa if inhaled, or penetrate through the skin after topical application, enter into the blood and cross the blood-brain barrier. Recent evidence supports the idea that the common constituents of essential oils also inhibit α-amylase, a starch digestive enzyme that plays an important role in the control of diabetes. The mint family is a fragrant plant family that contains most of the culinary herbs found in the Mediterranean diet. The Mediterranean diet is considered to be one of the healthiest diets in the world, and is found to be beneficial not only for the heart but also for the brain. Herbs used in this diet are rich in antioxidants that can prevent oxidative damage caused by free radicals. However, our study shows that they also contain biologically active compounds with potent α-amylase and acetylcholinesterase inhibitory activities. Consumption of fresh herbs can help boost memory and reduce sugar levels in the body. The use of herbs as a functional food could lead to significant improvements in health. Cognitive stimulation with medical food and medical herbs could delay development of cognitive decline, and improve the quality of life of Alzheimer's disease patients. This effect can be enhanced if combined with aromatherapy, topically or by inhalation, and/or by ingestion. Terpenes and terpenoids, the primary constituents of these essential oils are small, lipid soluble organic molecules that can be absorbed through the skin or across nasal mucosa into the systemic blood circulation. Many terpenes can also cross the blood-brain barrier. Therefore, topical application or inhalation of essential oils will also produce a systemic effect.

Safely Using TCM Herbs： Adverse Reactions and Precautions

Effects of Chinese herbs on lactation of rat and performance of offspring

An experiment was conducted to study the effects of different Chinese herbs on lactation in the rat. Seventy-two Sprague Dawley female rats at gestation day 18 were assigned to 9 groups randomly, with 8 rats each. Control rats were offered basal diets until the end of the weaning period. Rats in the other 8 groups were administered diets supplemented with 1% Medulla tetmpanacis （MT）, Astragalus membranacens （AM）, Vaccaria segetalis （VS）, Leonurus heterophyllus sweet （LHS）, Radix rehmarmiae preparata （RRP）, Squama man/t/s （SM）, Schisandra chinensis （SC）, Ligustrum lucidum （LL）, respectively. After parturition, the litter size was culled to 8 pups per dam. Pup weight and milk yield were significantly higher in the VS, LHS, AM and SM groups than these in the control group during middle and late lactation （P〈0.05 or P〈0.01）. The weight and feed intake were not different in the dams fed either diet.

Perspectives and challenges of tropical medicinal herbs and modern drug discovery in the current scenario

Tropical diseases such as malaria, tuberculosis, trypanosomiasis, and leishmaniasis, account for a large number of deaths annually. Herbs are an excellent source of tropical medicines. Many advancements and discoveries have taken place in the field of drug discovery but still, a major population of tropical diseases relies on herbal traditional medicine. There are some challenges related to policy implementation, efficacy, resistance and toxicity of tropical medicines. There are many tropical diseases such as such as schistosomiasis, leishmaniasis, African sleeping sickness, filariasis and chagas disease which are neglected because very few pharmaceutical companies have shown their interest in developing therapeutics against these diseases of poor people. There are many benefits associated with herbal medicine such as the cost of production, patient tolerance, large scale availability, efficacy, safety, potency, recyclability, and environment friendly. A large number of natural extracts such as curcumin, artemisinin, morphine, reserpine, and hypericin, are in use for treatment of different tropical diseases for a long time. The current review is to discuss the overview of tropical medicinal herbs, its scope and limitations in the modern drug discovery process.

Relationship of species diversity between overstory trees and understory herbs along the environmental gradients in the Tianshan Wild Fruit Forests, Northwest China

In forest ecosystems, interactions between overstory trees and understory herbs play an important role in driving plant species diversity. However, reported links between overstory tree and understory herb species diversity have been inconsistent, due to variations in forest types and environmental conditions. Here, we measured species richness(SR) and diversity(Shannon-Wiener(H') and Simpson's(D) indices) of overstory trees and understory herbs in the protected Tianshan Wild Fruit Forest(TWFF), Northwest China, to explore their relationships along the latitudinal, longitudinal, elevational, and climatic(current climate and paleoclimate) gradients in 2018. We found that SR, and H' and D diversity indices of overstory trees and understory herbs exhibited a unimodal pattern with increasing latitude and elevation(P<0.05) and negative associations with longitude(P<0.01). Along the climatic gradients, there were U-shaped patterns in SR, and H' and D diversity indices between trees and herbs(P<0.05). SR, and H' and D diversity indices for overstory tree species were positively associated with those for understory herbs(P<0.01). These findings indicate that overstory trees and understory herbs should be protected concurrently in the TWFF to increase effectiveness of species diversity conservation programs.

Microdilution inhibition test of Chinese herbs to assess their effect against clinical strains of Ureaplasma urealyticum in vitro

Objective：To explore the antibacterial effect of Chinese crude drugs against clinical strains of Ureaplasma urealyticum（UU）, including eight pure herbs and three compound herbs, and determine their minimal inhibitory concentrations（MICs）. Methods：Isolates were collected from clinical patients with UU infection, and cultured in UU broth. In order to test the different effects on clinical strains of UU, the assays were performed by microdilution inhibition tests, and MICs of the herbs against the clinical strains of UU were calculated. Results：The MICs of eight pure herbs against clinical strains of UU were as follows： Galla Chinensis：0.313-1.25 g/L; Fructus Forsythiae： 1.25-5.00 g/L; Cortex Phellodendri： 1.25-5.00 g/L; Radix Paeoniae Rubra： 1.25-2.50 g/L; Semen Plantaginis：2.50-10.00 g/L; Herba Lysimachiae： 5.00-20.00 g/L; Rhizoma Coptidis： 5.00-20.00g/L, Herba Houttuyniae： 10.00-20.00 g/L. The MICs of compound herbs were： Liuheji： 0.625-2.50 g/L; Bazhengsan： 5.00-20.00 g/L; Wulinsan：2.50-20.0 g/L.Conclusion：Galla Chinensis, Fructus Forsythiae, Cortex Phellodendrim, Radix Paeoniae Rubra, and Semen Plantaginis, exerted the stronger antibacterial effect against clinical strains of UU, whereas Herba Lysimachiae, Rhizoma Coptidis and Herba Houttuyniae, had relatively weaker activity against UU. Compound herbs, Bazhengsan and Wulinsan, and particularly Liuheji, also had antibacterial effects against UU. Further studies of the effects and mechanisms of action of Chinese crude drugs against UU infections are worthwhile.

Utilization of Dispersive Liquid-Liquid Microextraction Coupled with HPLC-UV as a Sensitive and Efficient Method for the Extraction and Determination of Oleanolic Acid and Ursolic Acid in Chinese Medicinal Herbs

Isomeric triterpenic acids of oleanolic acid (OA) and ursolic acid (UA) both have very low ultraviolet absorption and always exist in the same plant, so the separation and simultaneous determination of them have been a difficult task. In this study, a sensitive method combining dispersive liquid-liquid microextraction (DLLME) with HPLC-UV was developed for the extraction and determination of OA and UA in traditional Chinese medicinal herbs (CMHs). Variables influencing DLLME such as type and volume of extraction solvent, volume of dispersive solvent, ionic strength, aqueous phase pH, extraction time, centrifugation speed and time, and sample volume were investigated and optimized. Under the optimum conditions, both OA and UA attained favorable extraction efficiencies with enrichment factors 1378 and 933, respectively. The linear dynamic ranges of 0.07 - 30.4 μg?mL–1 for OA and 0.08 - 33.6 μg?mL–1 for UA were obtained with square correlation coefficients of 0.9963. The detection limits of OA and UA were both 0.02 μg?mL–1. The method recoveries ranged between 88.2% - 116.2% for OA and 85.7% - 108.2% for UA with the RSDs (n = 5) lower than 8.6%. The proposed method was successfully applied to concentrate and simultaneously determine these two triterpenic acids in Hedyotis diffusa and Eriobotrya japonica samples.

Antioxidant activity and hepatoprotective effect of 10 medicinal herbs on CCl4-induced liver injury in mice

BACKGROUND Many natural products confer health benefits against diverse diseases through their antioxidant activities.Carbon tetrachloride(CCl4)is often used in animal experiments to study the effects of substances on liver injury and the related mechanisms of action,among which oxidative stress is a major pathogenic factor.AIM To compare antioxidant and hepatoprotective activities of ten herbs and identify and quantify phytochemicals for the one with strongest hepatoprotection.METHODS The antioxidant activity of ten medicinal herbs was determined by both ferricreducing antioxidant power and Trolox equivalent antioxidant capacity assays.The total phenolic and flavonoid contents were determined by Folin–Ciocalteu method and aluminum chloride colorimetry,respectively.Their effects on CCl4-induced oxidative liver injury were evaluated and compared in a mouse model by administrating each water extract(0.15 g/mL,10 mL/kg)once per day for seven consecutive days and a dose of CCl4 solution in olive oil(8%,v/v,10 mL/kg).The herb with the strongest hepatoprotective performance was analyzed for the detailed bioactive components by using high-performance liquid chromatography-electrospray ionization source-ion trap tandem mass spectrometry.RESULTS The results revealed that all tested herbs attenuated CCl4-induced oxidative liver injury;each resulted in significant decreases in levels of serum alanine transaminase,aspartate transaminase,alkaline phosphatase,and triacylglycerols.In addition,most herbs restored hepatic superoxide dismutase and catalase activities,glutathione levels,and reduced malondialdehyde levels.Sanguisorba officinalis(S.officinalis)L.,Coptis chinensis Franch.,and Pueraria lobata(Willd.)Ohwi root were the three most effective herbs,and S.officinalis L.exhibited the strongest hepatoprotective effect.Nine active components were identified in S.officinalis L.Gallic acid and(+)-catechin were quantified(7.86±0.45 mg/g and 8.19±0.57 mg/g dried weight,respectively).Furthermore,the tested herbs displayed a range of in vitro antioxidant activities proportional to their phenolic content;the strongest activities were also found for S.officinalis L.CONCLUSION This study is of value to assist the selection of more effective natural products for direct consumption and the development of nutraceuticals or therapeutics to manage oxidative stress-related diseases.

Effect of Natural Phytogenic Extract Herbs on Physiological Status and Carcass Traits of Broiler Chickens

This paper was conducted to monitor the effect of mixed essential oils (AROMIX&#64;) as phytogenic extract herbs administration in drinking water on growth performance, hematological, biochemical, immunological statuses and carcass traits of broiler chickens. A total number of 240 unsexed broiler chicks (Cobb-500) strain, were randomly divided to four equal groups, 60 chicks each at seven days of age. The first group drank tap water (control), the second, third and fourth group were drank the same water, adding 1 ml AROMIX&#64;per 5, 10 and 15 liter tap water, respectively for 5 week of age. It was cleared from the results that there was a significant improve in feed conversion ratio, red and white blood cell counts, total protein, albumin, globulin, calcium, inorganic phosphorus and a relative reduction in the liver enzymes but in the normal range. However, it was observed that mix essential oils have no significant impact on carcass organs. High levels of the vital parameters, low levels of hepatic enzymes showed that birds health was good and relative improvement in immune system. The relative improvement of the absorption of minerals such as calcium and inorganic phosphorus to the positive role of essential oils. Administration in drank water was occasion, a regular activity of hepatic enzymes which can evidence safety and hepato-protective nature of these oils. Therefore, it is cleared from the results that the addition of these extract herbs in drinking water enhances the health meat, performance and physiological status of broiler chicks, which helps to obtain healthy meat and suitable for human consumption.

The Effect of TCM Herbs on Mitochondrial Functions: The Linkage between Qi and Mitochondria

The linkage between Qi and mitochondria was investigated by exploring the effect of Traditional Chinese Medicine (TCM) Qi-invigorating herbs on mitochondrial function at the biochemical and molecular levels. Three Chinese herbs (Astragali radix, Herba cistanche, Panax ginseng) were used to treat cultured mouse kidney cells and the generation of adenosine triphosphate (ATP) was measured. The Qi-invigorating herb, Astragali radix, was selected for further study using additional biological and molecular parameters, including ATP, reactive oxygen species (ROS), mitochondrial membrane potential (MMP), mtDNA copies, superoxide dismutase (SOD), glutathione (GSH), cell growth, cell viability and transcriptomes. We also chose two concentrations of Astragali radix to study the hormetic effect. The results indicated that: 1) Qi-invigorating herbs have significant effects on the function of mitochondria, with ATP production and the antioxidant capacity being significantly enhanced, and ROS levels being reduced, allowing for a more optimal oxidation environment. The effect of the herbs followed a hormetic curve with a stimulating effect at lower doses but an inhibiting effect at high doses;2) The growth of the cells was not affected despite numerous biochemical changes associated with mitochondrial function, indicating the powerful ability of mitochondria to maintain cellular homeostasis;3) The up-regulation of NOCT gene, related to nicotinamide adenine dinucleotide (NADH) synthesis, offers a molecular basis for the ATP-promoting effect of the Qi-invigorating herbs. This work provides additional insight into the efficacy of TCM herbs from a western perspective.
