Bacterial DNA gyrase is a proven target for antibacterial agents. Aim of this study was to investigate the in-vitro inhibitory effect of methanol extracts of CHDs against supercoiling activity of bacterial DNA gyrase. Fifteen CHDs were selected and extracted with methanol, respectively. Inhibitory effect of the extracts on DNA gyrase was tested using gel-based DNA supercoiling assay. Among fifteen CHDs tested, methanol extracts of Lonicerae Japonicae Flos (S2), Taraxaci Herba (S7), Glycyrrhizae Radix et Rhizoma Praeparata cum Melle (S8) demonstrated an obvious inhibitory effect against supercoiling activity of DNA gyrase, and the others were either less active or could not be determined with the present method. Moreover, it was likely that S7 and S8 inhibit gyrase in a concentration-dependent manner. In conclusion, DNA supercoiling assay is a promising method to study the inhibitory activity of CHDs on bacterial DNA gyrase. Some CHDs do have gyrase-inhibitory activity as proposed. Further investigations are needed to elucidate the inhibition mechanism of these CHDs on supercoiling activity of gyrase.展开更多

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.展开更多

It presently lacks an effective therapy for its complex pathogenesis. Adverse effects from Western drug-based medical intervention prevent long-term adherence to these therapies in many patients. Traditional Chinese medicine (TCM) has long been used to improve the treatment of PD by alleviating the toxic and adverse effects of Western drug-based intervention. Therefore, the aim of this study is to evaluate the efficacy and safety of Xifeng Dingchan Pill (XFDCP), a compound traditional Chinese herbal medicine, taken in conjunction with Western medicine in the treatment of PD patients at different stages in the progression of the disease. METHODS AND DESIGN: This is a multicenter, randomized controlled trial. In total, 320 patients with early- (n = 160) and middle-stage PD (n = 160) will be enrolled and divided evenly into control and trial groups. Of the 160 patients with early-stage PD, the trial group (n = 80) will be given XFDCP, and the control group (n = 80) will be given Madopar. Of the 160 patients with middle-stage PD, the trial group (n = 80) will be given XFDCP combined with Madopar and Piribedil, and the control group (n = 80) will be given Madopar and Piribedil. The Unified Parkinson's Disease Rating Scale scores, TCM symptoms scores, quality of life, change of Madopar's dosage and the toxic and adverse effects of Madopar will be observed during a 3-month treatment period and through a further 6-month follow-up period. DISCUSSION: It is hypothesized that XFDCP, combined with Madopar and Piribedil, will have beneficial effects on patients with PD. The results of this study will provide evidence for developing a comprehensive therapy regimen, which can delay the progress of the disease and improve the quality of life for PD patients in different stages. TRIAL REGISTRATION: This trial has been registered in the Chinese Clinical Trial Registry with the identifer ChiCTR-TRC-12002150.展开更多

In abroad, attention has been mainly payed to raising antisera and monocolonal antibodies against the endotoxin and the induced mediators. However, the allergic reactions and the cost are still the problems. Till now, there is no drug that can antagonize endotoxin with high effectiveness and low toxicity. Clinical treatments are still confined in inhibiting or killing the pathogen, and correcting the internal environmental disturbance. Being less toxic and rich in resources with low cost and less side-effects, screening of effective Chinese drugs for antagonizing endotoxin is of important and practical significance. Endotoxin belongs to the category of toxic evils, or more precisely, the heat toxin in TCM. Therefore the application of heat-clearing and detoxifying Chinese drugs to antagonizing endotoxins is consistent with the theory of TCM. Some achievements in this field are reported as follows.展开更多

文摘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.

文摘BACKGROUND: Parkinson's disease (PD) is a complicated disease, commonly diagnosed among the elderly, which leads to degeneration of the central nervous system. It presently lacks an effective therapy for its complex pathogenesis. Adverse effects from Western drug-based medical intervention prevent long-term adherence to these therapies in many patients. Traditional Chinese medicine (TCM) has long been used to improve the treatment of PD by alleviating the toxic and adverse effects of Western drug-based intervention. Therefore, the aim of this study is to evaluate the efficacy and safety of Xifeng Dingchan Pill (XFDCP), a compound traditional Chinese herbal medicine, taken in conjunction with Western medicine in the treatment of PD patients at different stages in the progression of the disease. METHODS AND DESIGN: This is a multicenter, randomized controlled trial. In total, 320 patients with early- (n = 160) and middle-stage PD (n = 160) will be enrolled and divided evenly into control and trial groups. Of the 160 patients with early-stage PD, the trial group (n = 80) will be given XFDCP, and the control group (n = 80) will be given Madopar. Of the 160 patients with middle-stage PD, the trial group (n = 80) will be given XFDCP combined with Madopar and Piribedil, and the control group (n = 80) will be given Madopar and Piribedil. The Unified Parkinson's Disease Rating Scale scores, TCM symptoms scores, quality of life, change of Madopar's dosage and the toxic and adverse effects of Madopar will be observed during a 3-month treatment period and through a further 6-month follow-up period. DISCUSSION: It is hypothesized that XFDCP, combined with Madopar and Piribedil, will have beneficial effects on patients with PD. The results of this study will provide evidence for developing a comprehensive therapy regimen, which can delay the progress of the disease and improve the quality of life for PD patients in different stages. TRIAL REGISTRATION: This trial has been registered in the Chinese Clinical Trial Registry with the identifer ChiCTR-TRC-12002150.
文摘Research into anticancer substances madefrom Chinese herbal drugs and their clinicalapplication is gaining international attention bythe medical profession of the more than 20analogues of camptothecine isolated from Camp-totheca tree in China, most exhibited anticanceractivity. Among them, 10-hydroxycamptothe-cine has a wide anticancer spectrum and is lesstoxic. In suspension, it exhibits some therapeu-tic effects on primary hepatic cancer, gastriccarcinoma, cancer of the urinary bladder andleukemia.
文摘In the recent decade, interest in treatment and prevention of many critical, severe and acute diseases caused by bacterial endotoxins has been aroused along with the advance of the knowledge on the nature of the endotoxin and the conditions involved. In abroad, attention has been mainly payed to raising antisera and monocolonal antibodies against the endotoxin and the induced mediators. However, the allergic reactions and the cost are still the problems. Till now, there is no drug that can antagonize endotoxin with high effectiveness and low toxicity. Clinical treatments are still confined in inhibiting or killing the pathogen, and correcting the internal environmental disturbance. Being less toxic and rich in resources with low cost and less side-effects, screening of effective Chinese drugs for antagonizing endotoxin is of important and practical significance. Endotoxin belongs to the category of toxic evils, or more precisely, the heat toxin in TCM. Therefore the application of heat-clearing and detoxifying Chinese drugs to antagonizing endotoxins is consistent with the theory of TCM. Some achievements in this field are reported as follows.
