Intratumor bacteria, which are involved with complex tumor development mechanisms, can compromise the therapeutic efficiencies of cancer chemotherapeutics. Therefore, the development of anti-tumor agents targeting intratumor bacteria is crucial in overcoming the drug inactivation induced by bacteria colonization. In this study, a double-bundle DNA tetrahedron-based nanocarrier is developed for intratumor bacteria-targeted berberine (Ber) delivery.

Methods: Altogether 130 children with pneumonia caused by multi-drug resistant bacteria admitted to our hospital from January 2016 to January 2019 were recruited as the study cohort. The children were randomly divided into a combined group (n=80, combined therapy) and a control group (n=50, cefoperazone sulbactam sodium therapy).
Objective: To study the effect of Bifidobacterium on the expression of β-defensin-2 (BD-2) in intestinal tissue of neonatal rats with necrotizing enterocolitis (NEC).
Methods: A total of 40 rats were randomly divided into four groups: normal control, Bifidobacterium control, NEC model, and Bifidobacterium treatment, with 10 rats in each group. A rat model of NEC was induced by hypoxia, cold stimulation, and artificial feeding.

Objective: To investigate the relationship between the quality of life (QOL) and disability level in patients with occupational disease and to investigate the influencing factors for QOL.
Methods: A total of 255 patients with occupational disease were selected from three specialized hospitals dedicated to occupational disease and the department of occupational medicine of one comprehensive hospital using cluster sampling from December 2013 to May 2014. A survey was carried out using WHOQOL-BREF and general questionnaire (including disability level), and statistical analysis was also performed using t test, F test, analysis of variance, and multivariate stepwise regression analysis.

Objective: To investigate the effect of adenosine and its agonist on hypoxia-induced right ventricular hypertrophy (RVH) and explore the underlying mechanism.
Methods: Fifty-six rats were randomly divided into normoxia group, hypoxia group, and treated hypoxia groups (with different treatments with adenosine, A1 receptor agonist CPA, A2 receptor agonist NECA, CPA plus A1 receptor inhibitor DPCPX, or NECA plus A2B receptor inhibitor MRS1754). The rats except for those in normoxia group were exposed to normobaric chronic hypoxia (9.
