RESUMO

The leaves of Vernonia amygdalina Delile of the family Asteraceae(also known as "bitter leaf"), rich in biological activities, are used as both medicine and food for a long time in West tropical Africa. They have been introduced into Southeast Asia and Fujian and Guangdong provinces of China in recent years. However, little is known about the properties of the plant in traditional Chinese medicine(TCM), which limits its combination with other Chinese medicinal herbs. In this study, 473 articles on V. amygdalina leaves were selected from PubMed, Web of Science, CNKI, Wanfang Data and VIP to summarize their components, pharmacological effects and clinical research. V. amygdalina leaves presented anti-microbial, hypoglycemic, anti-hypertensive, lipid-lowering, anti-tumor, anti-inflammatory, antioxidant, and other pharmacological effects. On the basis of the theory of TCM properties, the leaves were inferred to be cold in property and bitter and sweet in flavor, acting on spleen, liver, stomach and large intestine and with the functions of clearing heat, drying dampness, purging fire, removing toxin, killing insects and preventing attack of malaria. They can be used to treat dampness-heat diarrhea, interior heat and diabetes, malaria, insect accumulation and eczema(5-10 g dry leaves by decoction per day and an appropriate amount of crushed fresh leaves applying to the affected area for external use). Due to the lack of TCM properties, V. amygdalina leaves are rarely used medicinally in China. The determination of medicinal properties of the leaves is conducive to the introduction of new exotic medicinal herbs and the development of new TCM resources, which facilitated further clinical application and research and development of Chinese medicinal herbs.

RESUMO

This study aimed to investigate the anti-fatigue effect and mechanism of Lubian(Cervi Penis et Testis) on kidney Yin deficiency and kidney Yang deficiency mice. After one week of adaptive feeding, 88 healthy male Kunming mice were randomly divided into a blank group, a kidney Yin deficiency model group, a kidney Yin deficiency-Panacis Quinquefolii Radix(PQR) group, kidney Yin deficiency-Lubian treatment groups, a kidney Yang deficiency model group, a kidney Yang deficiency-Ginseng Radix et Rhizoma(GR) group, and kidney Yang deficiency-Lubian treatment groups, with eight mice in each group. The kidney Yin deficiency model and kidney Yang deficiency model were prepared by daily regular oral administration of dexamethasone acetate and hydrocortisone, respectively, and meanwhile, corresponding drugs were provided. The mice in the blank group received blank reagent. The treatment lasted 14 days. The exhaustive swimming time was measured 30 min after drug administration on the 14th day. On the 15th day, blood was collected from eyeballs and the serum was separated to determine the content of lactic acid(LD), blood urea nitrogen(BUN), lactate dehydrogenase(LDH), cyclic adenosine monophosphate(cAMP), and cyclic guanosine monophosphate(cGMP). The liver was dissected to determine the content of liver glycogen and the protein expression of phosphoinositide 3-kinase(PI3K) and protein kinase B(Akt). Compared with the kidney Yang deficiency model group, the kidney Yang deficiency-Lubian treatment groups showed increased body weight(P<0.05), relieved symptoms of Yang deficiency, decreased cGMP content(P<0.01), increased cAMP/cGMP(P<0.01), prolonged exhausted swimming time(P<0.01), reduced LD(P<0.01), elevated BUN content(P<0.01), increased liver glycogen content(P<0.01), and increased protein expression of PI3K and Akt in the liver(P<0.05). Compared with the kidney Yin deficiency model group, the kidney Yin deficiency-Lubian treatment groups showed increased body weight(P<0.01), relieved symptoms of Yin deficiency, increased content of cGMP(P<0.01), decreased cAMP/cGMP(P<0.01), prolonged exhausted swimming time(P<0.01), decreased LD(P<0.01), decreased BUN content(P<0.01), increased liver glycogen content(P<0.01), and increased protein expression of PI3K(P<0.05) and Akt in the liver(P<0.05). To sum up, Lubian can regulate Yin deficiency and Yang deficiency and increase glycogen synthesis by affecting the PI3K-Akt pathway, thereby exerting an anti-fatigue role.

RESUMO

"Taking drugs for a long term" is a qualitative expression of medication method based on the efficacy and safety of Chinese medicine, and the study on it is conducive to the full utilization of the efficacy and rational use of drugs. There are 148 drugs that can be taken for a long time recorded in Shen Nong's Classic of Materia Medica, accounting for 41% of the total drugs. This paper analyzed three-grade classification, natural qualities, four properties and five flavors, and efficacy features of the "long-term taking" drugs(LTTD), thus exploring the herbal source of traditional Chinese medicine health care and the rationality of effect accumulation by long-term taking. It was found that there were more than 110 top-grade LTTD in Shen Nong's Classic of Materia Medica, most of which were herbs, with sweet flavor, flat property, and no toxicity. The efficacies were mainly making body feel light and agile(Qingshen) and prolonging life. Eighty-three LTTD were included in the Chinese Pharmacopoeia(2020 edition). In the modern classification, tonic LTTD accounted for the most, followed by damp-draining diuretic LTTD and exterior-releasing LTTD. Twenty LTTD were included in the "List of Medicinal and Edible Products" and 21 were in the "List of Products Used for Health-care Food", involving in various modern health care effects, such as enhancing immunity, assisting in reducing blood lipids, and anti-oxidation. Shen Nong's Classic of Materia Medica is the classic source of traditional Chinese medicine health care, and its medication thought of taking drugs for a long term to accumulate effects has guiding significance for the regulation of sub-health and chronic diseases nowadays. The efficacy and safety of LTTD have been examined in practice for a long time, and some of the drugs are edible, which is unique in the whole cycle of health-care service, especially in line with the health-care needs in the aging society under the concept of Big Health. However, some records in the book are limited by the understanding of the times, which should be scientifically studied according to the Chinese Pharmacopoeia and the related regulations and technical requirements, under the attitude of eliminating falsifications and preserving the truth and keeping the right essence, so as to achieve further improvement, innovation, and development.

RESUMO

BACKGROUND: M2-type macrophages are inflammation-suppressing cells that are differentiated after induction by cytokines such as IL-4 or IL-13, which play an important regulatory role in inflammation and influence the regression of inflammation-related diseases. All-trans retinoic acid (ATRA) has an important role in suppressing immune-mediated inflammatory responses but the effect and underlying mechanism of ATRA on the polarization of M2 macrophages remains unclear. METHODS: Macrophages were isolated from peritoneal wash fluid, and IL-4 (20 ng/mL) was used to construct a m2-type macrophage polarization model. The model was incubated with different concentrations of ATRA (15 µg/ml, 30 µg/ml, 45 µg/ml) for 24 h, and pretreated macrophages with p38MAPKα inhibitor SB202190 (20 µM). MTT, Trypan blue staining, Annexin V-PE/7-AAD staining, flow cytometry, real-time PCR and western blotting were used to investigate the effect and mechanism of ATRA on the polarization of M2 macrophages. RESULTS: Compared with the IL-4 group, the proportion of F4/80+CD206+ M2-type macrophages was significantly higher in the ATRA group (P < 0.01). mRNA and protein expression levels of Arg-1, IL-10 and TGF-ß1 were as significantly higher (P < 0.01) in the ATRA group as phosphorylation levels of STAT6 and p38MAPK (P < 0.01). After pretreatment with the addition of the inhibitor SB202190, M2-type macrophages proportion and their associated factors expression were significantly (P < 0.01) reduced, as compared with those in the ATRA group, but they were comparable (P > 0.05) with the IL-4 group. CONCLUSION: The combination of ATRA and IL-4 activated the p38MAPK/STAT6-signaling pathway to promote polarization of M2 macrophages.

RESUMO

Background: Lepidium meyenii Walp. (Maca) has emerged as a functional plant food and traditional herb owing to its biological activities; Maca polysaccharides as an important active component of Maca have good immunomodulatory effect; however, studies on the immunomodulatory effect of Maca polysaccharides are mainly focused on macrophages; little attention has been devoted to the mechanisms and other immune cells. This study is aimed at investigating the immunomodulatory effects and mechanisms of Maca polysaccharides. Methods: Sixty mice were divided into five groups, and the mice were injected with cyclophosphamide to establish an immunosuppression model except for those in the common group. The body weights were measured, as well as immune-related indices, such as organ indices, haematological parameters, lymphocyte cycle, and proliferation, cytokine, and protein expression levels. Results: The weight loss and immune organ index decline caused by cyclophosphamide could be reversed by MP. Furthermore, MP increased WBC and HGB counts and reduced the ratio of G0/G1 phase obviously, increased the proportion of S phase and G2/M phase in peripheral blood lymphocytes, increased the counts of CD4+ T cells and the ratio of CD4+/CD8+, and reduced the inhibition rate of splenic lymphocytes. MP affected the production of cytokines by increasing IFN-γ, TNF-α, and IL-2 levels and by decreasing IL-4 levels. MP increased the mRNA expression of T-bet and the protein expression of Bcl-2 in the spleen and decreased the protein expression of caspase-3 and Bax. Conclusions: Maca polysaccharides might be the basic material for Maca's immunomodulatory effect. The mechanism was perhaps related to inhibiting lymphocyte apoptosis and promoting the balance of Th1/Th2 cell subsets.

RESUMO

Despite the remarkable similarities between convolutional neural networks (CNN) and the human brain, CNNs still fall behind humans in many visual tasks, indicating that there still exist considerable differences between the two systems. Here, we leverage adversarial noise (AN) and adversarial interference (AI) images to quantify the consistency between neural representations and perceptual outcomes in the two systems. Humans can successfully recognize AI images as the same categories as their corresponding regular images but perceive AN images as meaningless noise. In contrast, CNNs can recognize AN images similar as corresponding regular images but classify AI images into wrong categories with surprisingly high confidence. We use functional magnetic resonance imaging to measure brain activity evoked by regular and adversarial images in the human brain, and compare it to the activity of artificial neurons in a prototypical CNN-AlexNet. In the human brain, we find that the representational similarity between regular and adversarial images largely echoes their perceptual similarity in all early visual areas. In AlexNet, however, the neural representations of adversarial images are inconsistent with network outputs in all intermediate processing layers, providing no neural foundations for the similarities at the perceptual level. Furthermore, we show that voxel-encoding models trained on regular images can successfully generalize to the neural responses to AI images but not AN images. These remarkable differences between the human brain and AlexNet in representation-perception association suggest that future CNNs should emulate both behavior and the internal neural presentations of the human brain.

The information on memory-boosting health products published by the Department of Special Food Safety Supervision and Management,the State Administration for Market Regulation( SAMR) was collected and the Chinese patent medicines on DRUGDATAEXPY were searched. Microsoft Excel and the TCMISS were used to statistically analyze the characteristics of formulations. A total of 212 memory-boosting health products were obtained from SAMR,including 83 ones containing Chinese medicinal materials. Twelve Chinese herbal medicines showed a usage frequency ≥ 8,with 151 times in use. In DRUGDATAEXPY,258 similar Chinese patent medicines were collected.Twelve Chinese herbal medicines showed a usage frequency ≥ 58,with 907 times in use. Through unsupervised hierarchical entropybased clustering of the above-mentioned Chinese medicinal health products and Chinese patent medicines separately,5 and 12 new formulas were obtained. The selection of Chinese herbal medicines for the new formulas was consistent with the principles of traditional Chinese medicine( TCM) theories,i. e.,tonifying kidney and marrow,benefiting Qi,nourishing Yin,resolving phlegm,and eliminating stasis. According to TCM theories,syndrome differentiation of the users was conducted,and the formulas were designed following the correspondence of syndromes with formulas and Chinese herbal medicines. This study is expected to provide new ideas and methods for the development of Chinese medicinal health products and accurately guide practical applications to exert the advantages of TCM in health care based on syndrome differentiation and improve the effect of Chinese medicinal health products.

RESUMO

This study summarized and analyzed the current acne-relieving Chinese medicinal health products and Chinese patent medicines,aiming at providing references for the formulation and development of acne-relieving health products. The information on acne-relieving health products published by the Department of Special Food Safety Supervision and Management,the State Administration for Market Regulation( SAMR) was retrieved,and the Chinese patent medicines on DRUGDATAEXPY were searched. Microsoft Excel and the Traditional Chinese Medicine Inheritance Support System V2. 5( TCMISS) were employed to statistically analyze the characteristics of formulations. Forty-three acne-relieving health products were obtained,including 40 ones containing Chinese herbal medicines. Six Chinese herbal medicines showed a usage frequency ≥8,with 61 times in use totally,including Salviae Miltiorrhizae Radix et Rhizoma( 13),Lonicerae Japonicae Flos( 12),Taraxaci Herba( 11),ALOE( 9),Carthami Flos( 8),and Rhei Radix et Rhizoma( 8). A total of 29 Chinese patent medicines with similar efficacy were collected in DRUGDATAEXPY. Nine Chinese herbal medicines showed a usage frequency ≥6,with 63 times in use,including Rhei Radix et Rhizoma( 10),Glycyrrhizae Radix et Rhizoma( 8),Scutellariae Radix( 8),Lonicerae Japonicae Flos( 7),Angelicae Sinensis Radix( 6),Paeoniae Radix Rubra( 6),Astragali Radix( 6),Paeoniae Radix Alba( 6),and Gardeniae Fructus( 6). Through unsupervised hierarchical entropy-based clustering of the above-mentioned Chinese medicinal health products and Chinese patent medicines,five and three new formulas were obtained,respectively. The selection of Chinese herbal medicines was consistent with the principles of traditional Chinese medicine( TCM) theories in relieving acne,i. e.,dispelling exterior wind,ventilating lungs,clearing heat,dissipating mass,promoting diuresis,relaxing bowels,removing toxin,activating blood,resolving stasis,eliminating phlegm,and regulating Qi. According to the " lung governing skin and body hair" and " interior-exterior relationship between lung and large intestine" in TCM theories,the idea that acne could be treated by relieving constipation was proposed,which provided new methods and references for the research and development of Chinese medicinal health products.

RESUMO

Myrtus communis is a traditional medicinal aromatic plant in the Mediterranean. At present, the plant has been introduced and cultivated in the southern part of China, and it is mostly used for ornamental or cosmetic purposes. Based on literature analysis and the theory of Chinese medicine, we discussed the medicinal parts and properties of M. communis in this paper to provide a theoretical basis for exploring the medicinal value of M. communis and its compatibility with traditional Chinese medicines. Literatures were searched from Web of Science(core collection), PubMed, CNKI, VIP and Wanfang by using the set conditions as key words. Then the obtained literatures were screened and classified. Finally, a total of 376 articles were included, consisting of 44 reviews, 54 germplasm resources, 78 chemical researches, 48 studies on application, extraction, or quality, 18 human trials, 132 pharmacological studies, and 2 safety studies. Based on literature analysis and theories of Chinese medicine, the leaves of M. communis were finally selected as the medicinal part of Chinese medicine, and the traditional Chinese medicine properties of M. communis leaves were deduced as pungent, bitter, and cool. The channel tropisms of M. communis leaves included lung, liver, and large intestine, with functions of detoxifying, resolving a mass, and insecticide. It was used for mouth sores, vaginal itching, hemorrhoids and warts, etc.; appropriate amount shall be applied for external use, and the decoction form shall be used for washing the affected parts; 3-12 g equivalent product shall be used in decoction, and this herb shall be put into the decoction in a later stage. The clarification of the medicinal parts of M. communis, and the determination of the Chinese medicine properties of M. communis leaves would lay a theoretical foundation for its compatibility and application with Chinese medicines, and can do more contribution to the medical and healthcare industry in our country.

RESUMO

Kaempferiae Parviflorae Rhizoma is the dried rhizome of Kaempferia parviflora in Zingiberaceae. It is originated and widely distributed in Thailand and other tropical and subtropical regions, where it has been used as food and medicine for thousands of years. K. parviflora is also planted in Yunnan and other places of China, but its traditional Chinese medicine properties are not clear, which greatly limits its compatibility with traditional Chinese medicines. In this article, the English and Chinese literatures of K. parviflora were searched from Web of Science, PubMed, Scopus, CNKI, Wanfang, and VIP databases for research and analysis. The medicinal properties of K. parviflora were preliminarily discussed based on the theory of traditional Chinese medicine under the guidance of clinical application and research literatures. The traditional Chinese medicine properties of K. parviflora were inferred as follows: flat, acrid, sweet. The channel tropisms of K. parviflora included kidney, spleen, stomach, and liver. The function of K. parviflora included tonifying kidney to strengthen essence, tonifying Qi and invigorating spleen, soothing liver and relieving depression. K. parviflora was clinically applied for the diseases such as syndrome of kidney essence deficiency, sex apathy, deficiency of spleen Qi, lassitude and asthenia, a weary spirit, obesity, diabetes, liver Qi stagnation, depression, and restless. The equivalent of dry power is 1.5 g·d~(-1) and the equivalent of decoction is 1.5-6 g·d~(-1). The determination of traditional Chinese medicine properties of K. parviflora has indeed laid a theoretical foundation for its application in the field of traditional Chinese medicine and enriched traditional Chinese medicine resources.

RESUMO

BACKGROUND: Ganoderma lucidum has certain components with known pharmacological effects, including strengthening immunity and anti-inflammatory activity. G. lucidum seeds inherit all its biological characteristics. G. lucidum spore polysaccharide (GLSP) is the main active ingredient to enhance these effects. However, its specific biological mechanisms are not exact. Our research is aimed at revealing the specific biological mechanism of GLSP to enhance immunity and inhibit the growth of H22 hepatocellular carcinoma cells. METHODS: We extracted primary macrophages (Mø) from BALB/c mice and treated them with GLSP (800 µg/mL, 400 µg/mL, and 200 µg/mL) to observe its effects on macrophage polarization and cytokine secretion. We used GLSP and GLSP-intervened macrophage supernatant to treat H22 tumor cells and observed their effects using MTT and flow cytometry. Moreover, real-time fluorescent quantitative PCR and western blotting were used to observe the effect of GLSP-intervened macrophage supernatant on the PI3K/AKT and mitochondrial apoptosis pathways. RESULTS: In this study, GLSP promoted the polarization of primary macrophages to M1 type and the upregulation of some cytokines such as TNF-α, IL-1ß, IL-6, and TGF-ß1. The MTT assay revealed that GLSP+Mø at 400 µg/mL and 800 µg/mL significantly inhibited H22 cell proliferation in a dose-dependent manner. Flow cytometry analysis revealed that GLSP+Mø induced apoptosis and cell cycle arrest at the G2/M phase, associated with the expression of critical genes and proteins (PI3K, p-AKT, BCL-2, BAX, and caspase-9) that regulate the PI3K/AKT pathway and apoptosis. GLSP reshapes the tumor microenvironment by activating macrophages, promotes the polarization of primary macrophages to M1 type, and promotes the secretion of various inflammatory factors and cytokines. CONCLUSION: Therefore, as a natural nutrient, GLSP is a potential agent in hepatocellular carcinoma cell treatment and induction of apoptosis.

RESUMO

The depressant-like effects of albiflorin (AF) were studied on stressed chronic restraint stress (CRS) rats. Experimental rats were subjected to immobilization stress for a daily 6 h-restraining in a plastic restrainer for continuous 21 d and were treated with 30 or 15 mg·kg-1 of AF for 21 d. Control rats were maintained in completely non stressed conditions. Behavioral tests and biochemical analysis were applied to investigating a regulatory mechanism of anti-stress of AF. Treatment with AF significantly restored the depressant-like behaviors. Besides, AF increased the levels of 5-hydroxytryptophan (5-HT), 5-hydroxyindoleacetic acid (5-HIAA), noradrenaline (NE) and dopamine (DA) in the hippocampus and increased the level of brain-derived neurotrophic factor (BDNF) in serum and protein expression in hippocampus. In addition, AF decreased the levels of hypothalamo-pituitary-adrenal (HPA) cascade, reduced the level of NO and cGMP in serum and inhibited the overexpression of 5-HT2AR mRNA and protein expression. Taken together, AF can modulate the NO-mediated network pathway in the hippocampus against stress-induced depressive-like behaviors. These physiological and behavioral changes allow rats to avoid potential deleterious effects of stress that may result from chronically elevated levels of glucocorticosteroids over days.

RESUMO

With the development of society, more and more foreign natural medicines have entered China, but they are faced with the problem that they are not given with the traditional Chinese medicine(TCM) properties when they are used with other TCM. When we carried out the research on introducing foreign natural plant resources to TCM, gradually, a new research model and field with original characteristics of TCM--the study of new foreign introducing TCM had been formed. In the process of it, we explored and summarized research rules to form the research paradigm, which will be conducive to the standardization and scientization of new foreign introducing TCM research. For the research of foreign introducing TCM, we analyzed the research background, reviewed the application history, sorted out the research status, elaborated the concept and summarized the research achievements. On this basis, we put forward the concept and system of the modern research paradigm of new foreign introducing TCM, studied and clarified the core elements, properties and research principles of this paradigm, and summarized the research contents and methods of new foreign introducing TCM. We interpreted the foundation of paradigm construction from multiple perspectives. The paradigm was the practical application of theoretical innovation of TCM. Under the guidance of it, more and more varieties of new foreign introducing TCM will be studied, the study will be more standardized, the conclusions will be more scientific and reliable, which will inspire and guide more researchers to focus on the research of new foreign introducing TCM, and the paradigm itself will be constantly improved. The construction and application of the paradigm will certainly accelerate the innovative research of foreign introducing TCM and play a historic role in promoting the enrichment of traditional Chinese medicine varieties.

RESUMO

By consulting the literatures of foreign plant medicine Echinacea purpurea at home and abroad, this paper discusses the property and function of E. purpurea from the point of view of traditional Chinese medicine theory, so as to realize "herbalization", provide the theoretical basis of traditional Chinese medicine for the correct clinical application and rational compatibility of E. purpurea, and broaden the scope and varieties of clinical selection of traditional Chinese medicine. Relevant literatures of E. purpurea were selected from PubMed and CNKI databases and classified based on clinical application, chemical composition, pharmacological action, toxic and side effects. Those with a high reliability were screened out, including 313 articles in English and 46 in Chinese. Finally, the basic theory of traditional Chinese medicine was analyzed. In our view, E. purpurea features pungent and bitter tastes and a cold nature, and enters lung, spleen, heart meridians, with effects in evacuating wind-heat, clearing heat and detoxifying, invigorating Qi, strengthening body resistance, and treating wind-heat cold, sore throat swelling pain, cough, heat toxin stagnation, sore carbuncle swelling toxin, red swelling heat pain, body deficiency and multiple diseases, fatigue burnout. This paper analyzes the research literatures of E. purpurea, "herbalize" it, endows it with the property and function of traditional Chinese medicine, lays the foundation for further animal experiment and clinical research, and provides scientific theoretical guidance for the better application of E. purpurea in clinic and its proper compatibility and rational application. This research model will also provide reference for further studies of "traditional Chinese medicine" of foreign plant drugs, enrich traditional Chinese medicine resources, and promote the healthy and sustainable development of traditional Chinese medicine.

RESUMO

Noni is a dry and mature fruit of Morinda citrifolia, which is widely distributed in the islands in the southern Pacific Ocean and the Indochina Peninsula in Asia. It is edible and has been used as a natural medicine for thousands of years. At present, Noni has been legally introduced into China, but there is no clear standard of traditional Chinese medicine properties and clinical application of traditional Chinese medicine, which greatly limits the application of compatibility with traditional Chinese medicine in China. This article appllied our pioneering modern research technology of new herbal medicine outside of China, theoretically studied the traditional Chinese medicine properties of Noni, and scientifically guided the reasonable compatibility and application of Noni with traditional Chinese medicine. The Web of Science and PubMed databases were selected to access the literatures on Noni. The retrieval time was August 1, 2018, with Noni or Morinda citrifolia as the search term. A total of 862 articles were retrieved. By reading the titles and abstracts of the articles, in addition to repetitive and irrelevant literature, 251 scientific research literatures with reasonable design and high credibility were selected, including 25 clinical trials, 94 pharmacological experiments, and 51 chemical composition literatures. Through analysis of scientific research literatures, led by clinical experiments, supported by pharmacological experiments, combined with the research progress of chemical components, the medicinal properties were studied under the guidance of traditional Chinese medicine theory. The Chinese medicine property of Noni is flat, with acid and sweet flavor.The channel tropisms of Noni included kidney, liver and spleen. The function of Noni included tonifying kindey and liver, strengthening tendon and bone, yiqi yangyin. The clinical application of Noni is used for liver and kidney deficiency, waist and knee weakness, weak muscles and bones; Qi and Yin deficiency, tiredness and thirst. Taken as fruit pulp or dry powder, the equivalent of dried product is 1-4 g. Noni is also distributed in Taiwan, Hainan in China. Hainan, Yunnan have been cultivated and introduced. Give Noni a clear Chinese medicine property, and lay a theoretical foundation for the compatibility of Noni with traditional Chinese medicine, which can enrich the Chinese medicine resources and promote the development of Chinese medicine.

RESUMO

To investigate the effect of resolution components, such as Açaí oil, alcohol extract and water extract, on the temperature tendency animal behavior and intrinsic biochemical indexes, such ascyclic nucleotides and metabolic level, in mice with deficiency-heat and deficiency-cold syndrome, in order to study the characteristics of the cold and heat properties of each resolution component of Açaí and the material basis of cooling. KM mice were randomly divided into 12 groups, namely blank group, deficiency-heat model group, deficiency-heat+Açaí group, deficiency-heat+Açaí oil group, deficiency-heat+Açaí alcohol extract group, deficiency-heat+Açaí water extract group, deficiency-cold model group, deficiency-cold+Cinnamomi Cortex group, deficiency-cold+Açaí group, deficiency-cold+Açaí oil group, deficiency-cold+Açaí alcohol extract group, deficiency-cold+Açaí water extract group. The mice in deficiency-heat group were given thyroid tablet solution(160 mg·kg~(-1)), the mice in deficiency-cold group were given hydrocortisone solution(25 mg·kg~(-1)) through gastric perfusion every afternoon for 14 days, and each administration group was given the corresponding drug. The temperature tendency, cyclic nucleotides and metabolic level of animals were measured after the experiment. The Açaí alcohol extract was consistent with the Açaí powder, with a regulatory effect on the deficiency-heat model mice; Açaí oil and its water extract were consistent with Cinnamomi Cortex, with a regulatory effect on the deficiency-cold model mice. In this study, based on the parable theory of traditional Chinese medicine's properties and tastes, property of alcohol extract of Açaí was cool, while the property of oil and water extract were warm, the alcohol extract of Açaí was the material basis of Açaí cold medicine by the methods of homogeneous comparison and heterogeneous disproval.

RESUMO

To investigate the characteristics of the cold and heat properties of each resolution component of Açaí and the material basis of cooling by observing the effect of resolution components, such as Açaí oil, alcohol extract and water extract, on the neurotransmitter, endocrine hormone and immune factor level in mice with deficiency-heat and deficiency-cold syndrome. KM male mice were randomly divided into 12 groups, namely blank group, deficiency-heat model group, deficiency-heat+Açaí group, deficiency-heat+Açaí oil group, deficiency-heat+Açaí alcohol extract group, deficiency-heat+Açaí water extract group, deficiency-cold model group, deficiency-cold+Cinnamomi Cortex group, deficiency-cold+Açaí group, deficiency-cold+Açaí oil group, deficiency-cold+Açaí alcohol extract group, and deficiency-cold+Açaí water extract group. The mice in deficiency-heat group were given with thyroid tablet solution(160 mg·kg~(-1)), and the mice in deficiency-cold group were given with hydrocortisone solution(25 mg·kg~(-1)) by intragastric administration every afternoon for 14 days. The mice in each administration group received corresponding drug. The neurotransmitter, endocrine hormone and immune factor levels in the mice were measured after the experiment. The Açaí alcohol extract, consistent with the Açaí powder, showed a regulatory effect on the deficiency-heat model mice; Açaí oil and its water extract were consistent with Cinna-momi Cortex, showing a regulatory effect on the deficiency-cold model mice. In this study, on the basis of proving that Açaí was was cool in property, it also revealed that alcohol extract of Açaí was cool while oil and water extract were warm in property based on the effect of Açaí on neuro-endocrine-immune network. The results suggested that the medicine property of Açaí was the result of the comprehensive action of the resolution components with different properties, and the alcohol extract of Açaí was proved as the material basis of Açaí cold medicine by using the methods of homogeneous comparison and heterogeneous disproval.

RESUMO

Here we report a novel strategy for controllable preparation monodisperse alginate microcapsules with oil cores, where the thickness of the alginate shells, as well as the number and diversity of the oil cores can be tailored precisely. Monodisperse oil-in-water-in-oil (O/W/O) emulsions are generated in a microfluidic device as templates, which contain alginate molecules and a water-soluble calcium complex in the middle aqueous phase. Alginate microcapsules are produced by gelling O/W/O emulsions in oil solution with acetic acid, where the pH decreasing will trigger the calcium ions being released from calcium complex and cross-linking with alginate molecules. Increasing the alginate molecule concentration in emulsion templates affects little on the thickness of the microcapsules but improves their stability in DI water. The strength of alginate microcapsules can be reinforced by post cross-linking in calcium chloride, polyetherimide, or chitosan solution. Typical payloads, such as thyme essential oil, lavender essential oil and W/O emulsions are encapsulated in alginate microcapsules successfully. Furthermore, tailoring the thickness of the alginate shells, as well as the number and the diversity of the oil cores precisely by manipulation the emulsion templates with microfluidics is also demonstrated. The proposed method shows excellent controllability in designing alginate microcapsules with oil cores.
