[The Effect of γ-secretase Inhibitor Combined with BMSC on the aGVHD in Mice Model].

Objective: To establish the aGVHD mouse model，and investigate the regulatory effect and its mechanism of low-dose GSI combined with BMSC on aGVHD mice.

Methods: C57BL/6 (H-2b) and BALB/c (H-2d) were selected as donor and recipient of allogeneic transplantation to establish the aGVHD mouse model. BALB/c mice were randomly divided into 6 groups, which were the bone marrow cell infusion after irradiation (BM) group; the bone marrow cells + spleen cells after irradiation (BM+SC) group; the bone marrow cells + spleen cells + DMSO (BM+SC+DMSO) (transplant control) group; bone marrow cells + splenocytes +GSI after irradiation (BM+SC+GSI) group; bone marrow cells + spleen cells + bone marrow mesenchymal stromal infusion after irradiation cell (BM+SC+BMSC) group; bone marrow cells + spleen cells + bone marrow mesenchymal stromal cells +GSI infused after irradiation (BM+SC+BMSC+GSI) group.

Changes of Anti-tuberculosis Herbs Formula During Past Three Decades in Contrast to Ancient Ones.

Objective: To investigate the evolution of herbal medicine in treating tuberculosis (TB) and encourage anti-TB drug discovery and development.

Methods: In this study, 477 ancient traditional Chinese medicine formulae were collected from the Dictionary of Traditional Chinese Medicine Prescriptions and 172 modern Chinese medicine formulae (from 1986 to 2016) were collected by searching 4 databases: WanFang Data Knowledge Service Platform, China National Knowledge Infrastructure Database (CNKI), China Science and Technology Journal Database (VIP) and Chinese Bio-medical Literature and Retrieval System (SinoMed) in Chinese. We restricted the search to publications in Chinese.

Clinical isolates of Mycobacterium abscessus in Guangzhou area most possibly from the environmental infection showed variable susceptibility.

Background: Mycobacterium abscessus (M. abscessus) can cause a variety of human infections, involving the lung, skin and soft tissues, and is generally believed to be acquired from environmental sources. The aim of this study was to investigate the molecular diversity and antibiotic susceptibility of M.

[Influences of Mycobacterium tuberculosis on the levels of human acute monocytic leukemia cell line THP-1 apoptosis and death].

Objective: To explore the influences of Mycobacterium tuberculosis on the levels of human acute monocytic leukemia cell line THP-1 apoptosis and death.

Methods: Human acute monocytic leukemia cell line THP-1 were infected with Mycobacterium tuberculosis strains H37Ra, H37Rv, or Beijing genotype (BJTB), respectively, to construct the infection models. Cell apoptosis was detected using flow cytometry.

[Purification of the heparin-binding haemagglutinin adhesin of Mycobacterium tuberculosis and its application in diagnosis of tuberculosis].

Objective: To investigate the application of heparin-binding haemagglutinin adhesin (HBHA) in tuberculosis (TB) diagnosis.

Methods: We prepared native HBHA from cultivated Mycobacterium Bovis Calmetta Guerin (BCG) in Suton liquid medium. After BCG grew to the stationary status, native HBHA was acquired by specific CL-6B chromatography column binding heparin.

[Detection of streptomycin resistance in Mycobacterium tuberculosis clinical isolates by denaturing high-performance liquid chromatography and DNA sequencing].

Objective: To determine the rpsL and rrs gene mutation in Mycobacterium tuberculosis (M. tuberculosis) and compare the consistency between the results of denaturing high-performance liquid chromatography (DHPLC) and those of DNA sequencing.

Methods: The values of streptomycin minimum inhibitory concentration (MIC) against 215 M.

[Study on the genotype of Mycobacterium tuberculosis isolates from hospitals in Tianjin].

Objective: To explore the characteristics on molecular epidemiology of Mycobacterium tuberculosis isolates from hospitals in Tianjin area.

Methods: One hundred M. tuberculosis isolated strains were collected in succession from August 16th-December 25th, 2005 in Tianjin Haihe Hospital and genotyped by spoligotyping and multiple locus variable number-tandem repeat(VNTR).
