Antibacterial mechanism of Biochanin A and its efficacy for the control of Xanthomonas axonopodis pv. glycines in soybean.

Background: Xanthomonas axonopodis pv. glycines (Xag) is a hazardous pathogen able to cause bacterial pustule disease in soybean, reducing crop yield and quality. Although flavonoids rutin and genistein are known to play an important role in soybean defence, soybean is only able to produce Biochanin A in low concentration.

[A comparative study of the clinical effects between two kinds of negative-pressure wound therapy].

Objective: To compare the differences of the clinical effects, side effects and treatment-related cost between two kinds of negative-pressure wound therapy (NPWT).

Methods: Forty-four inpatients with acute, subacute, and chronic wounds were divided into simplified NPWT group (A group) and conventional NPWT group (B group) according to the random number table. Wounds of patients in A group were treated with gauze + continuous suction with hospital central negative pressure (-10.

[Observation on the therapeutic effects of negative-pressure wound therapy on the treatment of complicated and refractory wounds].

Objective: To study the effects of negative-pressure wound therapy (NPWT) on the treatment of complicated and refractory wounds.

Methods: Sixty-seven patients with complicated or refractory wounds admitted to our hospital from September 2005 to November 2008 were randomly divided into NPWT group (n = 35) and conventional treatment (CT) group (n = 32). Wounds of patients in NPWT group were treated with interrupted suction under a pressure of -16.
