[Progress on the regulation of quorum sensing in wastewater treatment].

Quorum sensing is a phenomenon that microorganisms secrete some signal molecules, when such molecules accumulate to a threshold level, which would realize the information communication by regulating specific gene expression. Quorum sensing, which is widely found in information communication of various microorganisms, regulates a variety of social behaviors, such as biofilm formation, public goods production, and gene horizontal transfer of bacteria. The phenomenon of quorum sensing is widespread in biological aggregates, such as activated sludge, biofilm and granular sludge.

[Influence of different skin reactions of acupoint-application on clinical outcomes in the prevention and treatment of bronchial asthma].

Objective: To observe the influence of different skin reactions of acupoint-application in summer on outcomes of prevention and treatment of bronchial asthma.

Methods: All of the bronchial asthma patients were treated with acupoint-application therapy in the dog-days of summer, once every ten days, 3 times altogether. After the treatment, according to scores of the skin reactions including flush, itching, pain, vesicles, etc.
