Clinical Effect and Prognosis of Off-Pump Minimally Invasive Direct Coronary Artery Bypass.

BACKGROUND Coronary artery bypass grafting (CABG) is a common procedure to circumvent the obstruction of coronary arteries when stents are unsuitable. CABG is a very traumatic surgery that requires redirecting blood flow to an external pump. Thus, this procedure has many risks during and after surgery, and minimizing these risks would greatly benefit the patients.

Serum TNF-α levels in children with congenital heart disease undergoing cardiopulmonary bypass: A cohort study in China and a meta-analysis of the published literature.

Objective: To investigate the changes in tumor necrosis factor alpha (TNF-α) serum levels after cardiopulmonary bypass (CPB) in children with congenital heart disease (CHD), followed by a meta-analysis to analyze the clinical value of TNF-α in CPB.

Methods: Our cohort study enrolled 67 CHD children, assigned into off-pump group (n=32) and CPB group (n=35). The TNF-α serum levels in two groups were detected by ELISA before the operation (T1), at the end of the operation (0 hour, T2), and after 24 hours of the operation (T3).

[Ecological technique of cultivating Coptis chinensis in woods and co-cultivating it with maize].

Objective: To establish ecologically new modes of cultivating Coptis chinensis in woods and co-cultivating it with maize.

Methods: Based on the experience obtained from plot comparative test and production test, we used application-oriented research methods, and established new Coptis chinensis cultivation techniques that protect the natural environment.

Results: Coptis chinensis was harvested 6 years after cultivation.
