[Evaluation of eutrophication level changes in Baiyangdian Lake based on multiple biological groups].

Baiyangdian Lake is the largest shallow lake in the North China Plain. Due to the increases in upstream water consumption in recent decades, the amount of natural water entering the lake has decreased, resulting in a significant drop in the water level of Baiyangdian Lake. Severe eutrophication has occurred in Baiyangdian Lake owing to the discharge of domestic sewage around the sub-lakes.

Anaphylactic shock caused by haemocoagulase injection in China.

Haemocoagulase injection is a mixture of purified enzymes isolated from the venom of , which is used for the prevention and treatment of haemorrhage. It is a relatively safe pharmacological agent that does not require a skin test prior to administration. However, following a literature search, 14 reported cases of anaphylactic shock caused by haemocoagulase injection were identified, including one lethal case in China.

Analysis of anaphylactic shock caused by 17 types of traditional Chinese medicine injections used to treat cardiovascular and cerebrovascular diseases.

Several reports describing anaphylactic shock following treatment of cardiovascular and cerebrovascular diseases with Chinese herbal injections were described. Our analysis of these reports showed that anaphylactic shock caused by traditional Chinese medicine (TCM) injections for the treatment of cardiovascular and cerebrovascular diseases is common but also sometimes fatal. Therefore, we proposed the following four suggestions for improving the clinical safety of delivering Chinese herbal injections and reducing the occurrence of allergic shock.
