Therapeutic effects of Buzhong Yiqi decoction in patients with spleen and stomach qi deficiency after routine surgery and chemotherapy for colorectal cancer.

Background: According to the theory of traditional Chinese medicine (TCM), the spleen and stomach are the basis of acquired nature and the source of qi and blood biochemistry. After surgery and chemotherapy, patients with colorectal cancer often develop spleen and stomach qi deficiency syndrome, leading to decreased immune function. Buzhong Yiqi decoction, a classic TCM prescription, has the effect of tonifying middle-jiao and invigorating qi, boosting Yang, and suppressing immune-related inflammation.

[Microcystin safety study during Cyanobacteria removal by pressure enhanced coagulation process].

Pressure enhanced coagulation and sedimentation technique is an effective way for blue algae treatment. It is not clear whether Cyanobacteria balloon rupture will cause Cyanobacteria cells rupture, resulting in high intracellular concentrations of microcystin LR leak into the water, affecting drinking water safety. Therefore, in this study experimental comparative study of pressure and pre-oxidation of water containing Cyanobacteria was carried out to examine the microcystin LR concentration changes and Cyanobacteria removal efficiency.
