  • Publication number: 20220380829
    Abstract: Disclosed are methods of identifying pathogens and determining their antimicrobial susceptibility. The methods comprise detecting biomarkers in a test sample, locating the sample in a phylogenetic tree based on biomarker information, obtaining drug susceptibility prediction rules based on the phylogenetic tree positioning of the sample, and determining the drug susceptibility of a pathogen according to the prediction rules. Further disclosed are an application of the phylogenetic tree in the preparation of pathogen identification and/or drug susceptibility diagnostic product, and a pathogen identification and drug susceptibility diagnostic kit.

  • Publication number: 20150283318
    Abstract: The current invention discloses methods to treat disease caused by virus infection, bacterial infection, parasites infection, autoimmune disease, disease caused by production of unwanted antibodies, sepsis as well as methods to treat cancer and methods for virus infection detection using blood purification method. The current invention provides a method to treat pathogen infection by inactivating the pathogens in the blood. During the treatment, blood is withdrawn from a patient and is separated into its plasma and cellular components. The plasma portion is treated with physical means such as UV radiation to inactivate the pathogens inside and then is returned to the patient. The current invention also provide a method to treat cancer especially to prevent tumor metastasis and tumor recurrence by removing and/or inactivating (e.g. killing) the circulating tumor cells (CTC) in the blood after removing the tumor or treating the tumor with therapeutical means.

  • Patent number: 5375693
    Abstract: Methods and compositions are disclosed utilizing metabolic derivatives of terfenadine for the treatment of allergic disorders while avoiding the concomitant liability of adverse effects associated with the terfenadine. The metabolic derivatives of terfenadine are also useful for the treatment of retinopathy and other small vessel disorders associated with diabetes mellitus and such other conditions as may be related to the antihistamine activity of terfenadine. For example, the metabolic derivatives of terfenadine are useful for the treatment of asthma, motion sickness, and vertigo, without the concomitant liability of adverse effects associated with terfenadine.
