Methods: Female Sprague-Dawley rats were randomly divided into four groups: normal (N), central precocious puberty (CPP) model (M), CPP fed with normal saline (S) and CPP fed with Nourishing “Yin”-Removing “Fire” Chinese herb mixture (TCM). Rats of postnatal day 5 were given a single subcutaneous injection of 240 μg danazol to establish CPP model rats. Rats of S and TCM groups were continuously administered with saline or nourishing “Yin”-removing “Fire” Chinese herb mixture since postnatal day 15. The expression of GABABRs was detected by means of real-time PCR and immunohistochemistry. Results: The expression of hypothalamic GnRH mRNA in M was significantly increased on the day of pre-puberty when compared with that of N (P < 0.01). On the day of onset-puberty, LH levels were higher in M than those in N (P < 0.01), while the serum E2 and LH levels of TCM decreased when compared with those of M (P <sub>B1</sub> receptor (GABABR1) immunoreactive cells in the arcuate nucleus (ARN) was decreased in M when compared with that of N (P < 0.05) and increased in TCM compared with that of M (P < 0.05);simultaneously, the expression of GABABR1 mRNA in hypothalamus was significantly decreased in M when compared with that of N (P < 0.01) and increased in TCM compared with that of M (P < 0.01). On the day of onset-puberty, the number of GABABR1 immunoreactive cells in medial septum (MS) was decreased in M compared with that in N (P < 0.05) and increased in TCM comparing with that of M (P < 0.05);meanwhile, the mRNA expression of GABABR1 in hypothalamus was decreased in M compared with that in N (P <sub>B2</sub> receptor (GABABR2) immunoreactive cells in the ARN, MS and diagnonal band of broca (DBB) were decreased in M when compared with those of N (P < 0.05) and increased in TCM compared with those of M (P < 0.05) on the day of onset-puberty. At the same time, the mRNA expression of GABABR2 was significantly decreased in M compared with that of N (P < 0.01). Conclusions: These results indicated that the GABABRs might involve in the curative effect of Nourishing “Yin”-Removing “Fire” Chinese herbal mixture on CPP rats.展开更多

Methods: From perspective of systems biology, we used Associate Network to identify useful relationships among "Nature- Family-Component" of Herbs. In this work, Associate Network combines association rules mining method and network construction method to evaluate the complicate relationship among "Nature-Family-Component" of herbs screened. Results: The results of association rules mining showed that the families had a close relationship with nature properties of herbs. For example, the families of Magnoliaceae, Araceae had a close relationship with hot nature with confidence of 100%, the families of Cucurbitaceae has a close relationship to cold nature with confidence of 90,91%. Moreover, the results of constructed Associate Network implied that herbs belonging to the same families generally had the same natures. In addition, some herbs belonging to different families may also have same natures when they contain the same main components. Conclusion: These results implied that the main components of herbs might affect their natures; the relationships between families and natures were based on the main compounds of herbs.展开更多

[ Method] Pigs artificially infected by Toxoplasma gondii were treated with compound suffonamide and a self-designed Chinese herbs formula, and the quantities of toxoplasma in ascites were determined. Animal regression experiment was per- formed after mice were inoculated with pathological samples of the pigs infected with toxoplasma. After treatment with integrated Chinese herbs and western medicine, the clinical manifestations of pigs were observed and the level of circulating antigen (CAg) in sera was detected. Curative effect indexes of integrated Chinese herbs and western medicine-treated group were compared with that of Chinese herbs-treated group, western medi- cine-treated group and positive control group. [ Result] All the toxoplasma trophozoites were killed by integrated and westem medicine. Regression expedment results showed that toxoplasma appeared only in one mouse that was inoculated with brain of pig. The treated pigs had nonsignificant clinical symptoms; the peak of serum CAg was lower than that of the positive control group and CAg turned negative faster than that of Chinese herbs-treated group, westem medicine-treated group, and positive control group. [ Conclusion] The integrated Chinese herbs and western medicine has good effect on the treatment of swine toxoplasmosis.展开更多

It is believed that a multiple-gene inheritance is involved and it also involves various factors such as immunity, inflammation, cell proliferation, apoptosis, neural media, etc. Since cytokines are key mediators in inflammation, a number of Chinese medicines (CMs) have been reported to have certain antagonist effects on pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α), platelet active factor (PAF) and interleukin-8 (IL-8). Some researches on CMs have made significant breakthroughs in psoriasis by intervening with cytokines. Abnormalities with keratinocyte proliferation and apoptosis are considered to be present in patients with psoriasis and a number of studies show that the mechanism of CMs on psoriasis may be through the inhibition of the keratinocyte proliferation and induction of apoptosis. Other studies also show that the inhibition of fibroblast-secreted cytokines could regulate keratinocyte proliferation and differentiation and reduce the level of Calcitonin gene-related peptide (CGRP) in plasma and in lesions so as to slow down the process of inflammation and proliferation in psoriasis. The most commonly used models for psoriasis are the scaled tails or the vaginal epithelium of mice in China. They were used to observe the histopathological changes after the model mice were treated with CMs with the inhibition on the mitosis of vaginal epithelium or promotion of granular layer in rat tail taken as the indices of clinical efficacy. A variety of signs occur in psoriasis patients with TCM blood-stasis syndrome type and the effect of CMs in activating blood circulation to remove blood stasis on psoriasis suggested that the mechanism of CMs may be partially correlated to hemorrheology and microcirculation. Along with the continuous development of the biosciences, some TCM theories for psoriasis have been confirmed by laboratory studies. However, the exploration into traditional Chinese medicines' biomechanics in psoriasis and the therapeutic mechanism of CMs by integrative medicine still requires further studies.展开更多

Methods: From perspective of systems biology, we used Associate Network to identify useful relationships among "Nature- Family-Component" of Herbs. In this work, Associate Network combines association rules mining method and network construction method to evaluate the complicate relationship among "Nature-Family-Component" of herbs screened. Results: The results of association rules mining showed that the families had a close relationship with nature properties of herbs. For example, the families of Magnoliaceae, Araceae had a close relationship with hot nature with confidence of 100%, the families of Cucurbitaceae has a close relationship to cold nature with confidence of 90,91%. Moreover, the results of constructed Associate Network implied that herbs belonging to the same families generally had the same natures. In addition, some herbs belonging to different families may also have same natures when they contain the same main components. Conclusion: These results implied that the main components of herbs might affect their natures; the relationships between families and natures were based on the main compounds of herbs.

文摘Objective:Identifying novel strategies to prevent particulate matter(PM)-induced lung injury is crucial for the reduction of the morbidity of chronic respiratory diseases.The combined intervention represented by herbal formulae for simultaneously targeting multiple pathological processes can provide a more beneficial effect than the single intervention.The aim of this paper is therefore to design a safe and effective medicinal and edible Chinese herbs(MECHs)formula against PM-induced lung injury.Methods:PM-induced oxidative stress,inflammatory response and apoptosis A549 cell model were used to screen anti-oxidant,anti-inflammatory and anti-apoptotic MECHs,respectively.A network pharmacology method was utilized to rationally design a novel herbal formula.Ultra performance liquid chromatography-mass spectrometer was utilized to assess the quality control of MECHs formula.The excretion of magnetic iron oxide nanospheres of the MECHs formula was estimated in zebrafish.The MECH formula against PM-induced lung injury was investigated with mice experiments.Results:Five selected herbs were rationally designed to form a new MECH formula,including Citri Exocarpium Rubrum(Juhong),Lablab Semen Album(Baibiandou),Atractylodis Macrocephalae Rhizoma(Baizhu),Mori Folium(Sangye)and Polygonati Odorati Rhizoma(Yuzhu).The formula effectively promoted the magnetic iron oxide nanospheres excretion in zebrafish.The mid/high dose formula significantly prevented PM-induced lung damage in mice by enhancing the activity of SOD and GSH-Px,reducing the MDA and ROS level and attenuating the upregulation of pro-inflammatory cytokine(IL-6,IL-8,IL-1βand TNFa),down regulating the protein expression of NF-κB,STAT3 and Caspase-3.Conclusion:Our findings suggest that the effective MECHs formula will become a novel strategy for preventing PM-induced lung injury and provide a paradigm for the development of functional foods using MECHs.
文摘Objective: To study the effects of 24 Chinese medicinal herbs on nucleic acid, protein and cellcycle of human lung adenocarcinoma cells. Methods: Using flow cytometry the authors analysed the effects of 24Chinese medicinal herbs (CMH) in compound recipe on proliferation index (PI), DNA index, protein index andratio of various phases in cell cycle of human lung adenocarcinoma cells (SPC-A-1). Results: The PI was morethan 20%, in 4 CMH, while 3 CMH, Gynostemma Pentaphylla, Radix Glehnia, and Radix Ginseng couldstrengthen the body resistance. That suggested using CMH of strengthening body resistance could not only serveas conventional ionic but also as tumor cell inhibitor. Meanwhile the action points of 24 CMH on cell cycle weredifferent from one another. Conclusions: According to these results, Chinese recipes were more effective in clinical practice.
文摘Objective: To find new photosensitizers from Chinese medicinal herbs for cancer photodynamic therapy. Methods: The extracts of thirteen herbs were examined: (1) Their fluorescence excitation wave lengths and emission wave lengths; (2) Their fluorescence intensity in living cells and (3) Their distribution and localization in the living cells and the fixed cells both stained in each extract, and responses of cell fluorescence intensity to pH value change. Furthermore, the herb's anticancer photosensitive efficiencies were studied by using BGC823 human stomach cancer cells. Results: Cortex Phellodendri and Rhizoma Coptidis, were found with optimal fluorescence properties as photosensitizers in this test. The latter could remarkably reduce the cell metabolic viability, proliferative ability and increase the cell mortality when the cells exposed to both drugs and luminance but not to drug only. Conclusions: The potential of Chinese medicine as a new kind of photosensitizer and its possibility for using in anticancer photodynamic therapy are existed.
文摘The inhibitory activities of more than 40 species of Chinese medicinal herbs or their singlechemical components against simian immunodeficiency virus (SIV) have been studied. The study revealedthat four species of medicinal herbs and a single chemical component had a more than 50% inhtbition ef-fect on SIV antigen expression. and the inhibitory rate of five other herbs on SIV antigen expression wasbetween 30%-50%. The results suggest Chinese medicinal herbs could inhibit SIV activity.
文摘[ Objective] To evaluate the efficacy of integrated Chinese herbs and western medicine on the treatment of swine toxoplasmosis, in order to increase cure rate and lower recurrence rate. [ Method] Pigs artificially infected by Toxoplasma gondii were treated with compound suffonamide and a self-designed Chinese herbs formula, and the quantities of toxoplasma in ascites were determined. Animal regression experiment was per- formed after mice were inoculated with pathological samples of the pigs infected with toxoplasma. After treatment with integrated Chinese herbs and western medicine, the clinical manifestations of pigs were observed and the level of circulating antigen (CAg) in sera was detected. Curative effect indexes of integrated Chinese herbs and western medicine-treated group were compared with that of Chinese herbs-treated group, western medi- cine-treated group and positive control group. [ Result] All the toxoplasma trophozoites were killed by integrated and westem medicine. Regression expedment results showed that toxoplasma appeared only in one mouse that was inoculated with brain of pig. The treated pigs had nonsignificant clinical symptoms; the peak of serum CAg was lower than that of the positive control group and CAg turned negative faster than that of Chinese herbs-treated group, westem medicine-treated group, and positive control group. [ Conclusion] The integrated Chinese herbs and western medicine has good effect on the treatment of swine toxoplasmosis.
文摘Psoriasis is a common, chronic, recurrent inflammatory skin disorder whose etiology is still unknown. It is believed that a multiple-gene inheritance is involved and it also involves various factors such as immunity, inflammation, cell proliferation, apoptosis, neural media, etc. Since cytokines are key mediators in inflammation, a number of Chinese medicines (CMs) have been reported to have certain antagonist effects on pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α), platelet active factor (PAF) and interleukin-8 (IL-8). Some researches on CMs have made significant breakthroughs in psoriasis by intervening with cytokines. Abnormalities with keratinocyte proliferation and apoptosis are considered to be present in patients with psoriasis and a number of studies show that the mechanism of CMs on psoriasis may be through the inhibition of the keratinocyte proliferation and induction of apoptosis. Other studies also show that the inhibition of fibroblast-secreted cytokines could regulate keratinocyte proliferation and differentiation and reduce the level of Calcitonin gene-related peptide (CGRP) in plasma and in lesions so as to slow down the process of inflammation and proliferation in psoriasis. The most commonly used models for psoriasis are the scaled tails or the vaginal epithelium of mice in China. They were used to observe the histopathological changes after the model mice were treated with CMs with the inhibition on the mitosis of vaginal epithelium or promotion of granular layer in rat tail taken as the indices of clinical efficacy. A variety of signs occur in psoriasis patients with TCM blood-stasis syndrome type and the effect of CMs in activating blood circulation to remove blood stasis on psoriasis suggested that the mechanism of CMs may be partially correlated to hemorrheology and microcirculation. Along with the continuous development of the biosciences, some TCM theories for psoriasis have been confirmed by laboratory studies. However, the exploration into traditional Chinese medicines' biomechanics in psoriasis and the therapeutic mechanism of CMs by integrative medicine still requires further studies.
