Recent advances of histone modification in gastric cancer.

Epigenetics play important roles during development progress of tumor. The histone modifications are the most important constituted field. Recently, accumulating research focused on exploring the roles of those modifications in regulating tumorigenesis.

[Application of EITB in immunodiagnosis of cysticercosis].

Objective: To establish a sensitive and specific method EITB for the immunodiagnosis of cysticercosis.

Methods: Two-dimensional electrophoresis was used to analyze and purify the cyst fluid antigen. Western blotting using the sera of patients with cysticercosis, hydatidosis, and other heteroserum was used to screen the specific antigens.

[The correlation between DDVP resistance of Culex pipiens pallens and esterase activity].

Objective: To detect the resistance index and esterase activity of each generation of DDVP-resistant Culex mosquitoes and analyze the relationship between insecticide resistance and esterase.

Methods: WHO bioassay and micro-plate measurement were used for the detection.

Results: The resistance index increased to 12.
