83 results about "Bcg bladder instillation" patented technology

BCG is used in the treatment of superficial forms of bladder cancer. Since the late 1970s, evidence has become available that instillation of BCG into the bladder is an effective form of immunotherapy in this disease. While the mechanism is unclear, it appears a local immune reaction is mounted against the tumor.

Medicine combination and application thereof in preparing preparations for treating chronic hepatitis B

The invention relates to a medicine combination and the application thereof in preparing preparations for treating chronic hepatitis B. The combination comprises a medicine combination with polysaccharide nucleic acid of bacillus calmette guerin as the active component and a Chinese traditional medicine combination, wherein the Chinese traditional medicine combination is prepared from astragalus, herba artemisiae scopariae, oldenlandia diffusa, herba lysimachiae, codonopsis pilosula, processed polygonum capitatum, salvia, radix paeoniae alba, chinaberry fruit, taraxacum, cortex moutan, poria and atractylodes; the polysaccharide nucleic acid of bacillus calmette Guerin is nonspecific immunity active reinforcer, and can effectively restrain the reproduction of hepatitis virus and promote the rapid negative turning of HBV-DNA and HbeAg; and the Chinese traditional medicine combination has the efficacy of invigorating qi and spleen, promoting blood circulation by removing blood stasis and clearing away heat and toxic material. The medicine combination can reduce the incidence rate of variation and drug resistance and effectively promote the improvement under the condition of improving the healing efficacy, and provides a novel, safe and effective drug choice for clinics.

Recombinant bacillus calmette-guerin vaccine strain with over-expression mycobacterium tuberculosis Rv3586 and application of recombinant bacillus calmette-guerin vaccine strain

The invention relates to a recombinant bacillus calmette-guerin vaccine strain with over-expression mycobacterium tuberculosis Rv3586 and application of the recombinant bacillus calmette-guerin vaccine strain. Plasmids with encoding genes of the mycobacterium tuberculosis Rv3586 are transformed into bacillus calmette-guerin vaccine, and the recombinant bacillus calmette-guerin vaccine strain can be obtained by means of screening, is called as Bacillus calmette-Guerin rBCG-DisA and is called as rBCG-DisA for short, and a preservation number of the bacillus calmette-guerin vaccine strain is CCTCC M 2016335. The recombinant bacillus calmette-guerin vaccine strain and the application have the advantages that the recombinant bacillus calmette-guerin vaccine strain with the over-expression mycobacterium tuberculosis Rv3586 has merits of target antigens and bacillus calmette-guerin vaccine and can be used for individual immunization, or booster immunization can be carried out by the recombinant bacillus calmette-guerin vaccine strain and mycobacterium tuberculosis Ag85B-ESAT6 subunit vaccine, high immune response of normal and affected mice can be induced, the mycobacterium-resistant protective ability of organisms can be improved, and accordingly the recombinant bacillus calmette-guerin vaccine strain has an excellent application prospect.

Reagent and method for detecting Mycobacterium tuberculosis infection in vitro

InactiveCN102305855AValid in vitro assayOvercome the disadvantages of unsatisfactory effectImmunoglobulins against bacteriaFermentationAntigenParatuberculosis
The invention discloses a reagent and a method for detecting Mycobacterium tuberculosis infection in vitro. The reagent comprises a segment of specific T cell reactive polypeptide, namely M232 polypeptide shown as SEQ ID No.1 and screened from early secreting antigen target-6 (ESAT-6) polypeptide; and the M232 polypeptide is contacted with a T cell of a Mycobacterium tuberculosis host to detect cell factors released by the T cell and determine whether the T cell identifies the M232 polypeptide. The invention has the advantages of high sensitivity, no influence of Bacillus Calmette-Guerin (BCG) vaccine and nontuberculosis mycobacterial vaccine, high specificity, capacity of detecting patients with active pulmonary tuberculosis and patients with potential infection, and capacity of detecting healthy Mycobacterium tuberculosis contacts. The invention is particular suitable for detecting tuberculosis and/or potential infection of the tuberculosis for Chinese people. The invention also relates to a kit for detecting Mycobacterium tuberculosis infection in vitro, which comprises two mixed polypeptides, namely M232 and M233, and a tool for detecting the identification of the T cell on protein, or polypeptide or analogs of the polypeptide.

Prediction method and prediction system of irresponsive gamma globulin Kawasaki disease

The invention provides a prediction method and prediction system of an irresponsive gamma globulin Kawasaki disease. The method comprises the following steps that 21 original parameters of SVM model building are collected; the modelling original parameters comprise gender, age, fever time during treatment, clinical classification, CRP detection value, WBC value, PLT value, Hb value, ALT value, AST value, ALB value, gamma globulin using time and clinical diagnosed symptom indicators; the clinical diagnosed symptom indicators comprise conjunctival injection, erythra, cracked lips, a strawberry-like tongue, lymphadenectasis of a neck, hard and swollen hands and feet, digit peeling, crissum peeling and a red and swollen bacillus calmette-guerin scar; discretization is conducted on the original parameters to obtain SVM characteristic values corresponding to the original parameters; the SVM characteristic values are regarded as base data, a SVM model is built, and through the SVM model, a complication with irresponsive gamma globulin of the Kawasaki disease is predicted. By means of the prediction method and prediction system, early intervening treatment can be conducted on a patient, recovery of damage to a coronary artery is promoted, and the prediction method and prediction system have important significance and value on diagnosis and treatment of the Kawasaki disease in the future.

The invention relates to a recombinant BCG vaccine rBCG-IFN alpha-2b for secreting human IFN alpha-2b and a construction method and an identification method thereof, wherein a BCG vaccine Ag85B signal peptide fragment which has the function of secretion and genes of human IFN alpha-2b are cloned to pMV261 by the genetic engineering technology, and a BCG vaccine shuttle expression vector pMV261-Ag85B-IFN alpha-2b is obtained; and the vector is induced into BCG by the electrotransformation technology, and the recombinant BCG vaccine rBCG-IFN alpha-2b is established; and the human IFN alpha-2b can be highly efficiently secreted in virtue of the secretion function of the pMV261-Ag85B-IFN alpha-2b on BCG replication and signal peptide. The recombinant BCG vaccine rBCG-IFN alpha-2b obtained not only keeps the immunogenicity of the prior BCG but also can continuously secrete the cell factor-the IFN alpha-2b, thereby improving the immunocompetence of the BCG; the IFN alpha-2b can be directly acted on tumor cells to inhibit proliferation and induced differentiation of the tumor cells, has good antitumor action, and can reduce the application dosage and reduce the toxic and side effect caused by the BCG; and the IFN alpha-2b solves the problems of large application dosage, high incidence rate of side effects, short response time and expensive cost caused by exogenous IFN alpha-2b.
