[Act of Arc siRNA via lentivirus on the memory consolidation of amygdala-kindled rats].

Objective: To explore the memory consolidation related role of gene Arc in amygdala-kindled rats.

Methods: A total of 60 male amygdala-kindled rats were divided equally into 3 groups: 0.9% sodium chloride injection, null vector lentivirus injection and silencing lentivirus injection.

[The effects of low-frequency electric stimulus on hippocampal of Effects of low-frequency electric stimulus on hippocampal of α5 subunit of extra synapse GABAA receptor in kainic acid-induced epilepsy rats].

Objective: To explore the effects of low-frequency electric stimulus (LFS) on hippocampal of α5 subunit of extrasynaptic GABAA receptor in kainic acid-induced epilepsy rats and explore the possible mechanism of LFS on hippocampus to treat epilepsy.

Methods: A total of 32 male Sprague-Dawley rats were divided randomly into 4 groups:epileptic, pseudo-surgery, LFS treatment and control. The expression of α5 subunit of extrasynaptic GABAA receptor and the association with the curative effects of LFS were evaluated by behavioristics, real-time fluorogenic quantitative polymerase chain reaction (PCR) and Western blot.

Relationship between the transmission of schistosomiasis japonica and the construction of the Three Gorge Reservoir.

Objective: To study the relationship between the changes of environment and the transmission of Schistosomiasis japonica after the construction of the Three Gorge Reservoir.

Methods: On the basis of the predictive data on changes of water level and sediment in the middle and lower reaches of the Yangtze River after the dam construction provided by the Yangtze River Committee on Water Conservancy, corresponding data were collected and analyzed. In order to understand the effects of changes of water level and sediment on Oncomelania hupensis, the intermediate host of Schistosoma japonicum, field surveys and ecologically intimated experiments were done.
