[Spatial distribution and risk factors of tuberculosis in Songjiang district, Shanghai during 2006 and 2009].

Objective: To identify spatial distribution and risk factors among tuberculosis (TB) cases in Songjiang district, Shanghai, 2006 - 2009.

Methods: All active TB cases and all bacteriologically confirmed TB cases diagnosed during the period from 2006 to 2009 were recruited into the study. Spatial scan statistics were used to identify spatial clusters.

[Studies of the association between angiotensinogen gene regulation and cytokines in essential hypertension].

This study is to explore the association between M235T allele polymorphism of angiotensinogen (AGT) gene and cytokines using essential hypertension probands research method. In hypertensives and controls, polymerase chain reaction combined with restriction endonuclease digestion was used to detect the target genotype variation, and enzyme-lined immunosorbant assay (ELISA) was used to detect the cytokine concentrations (IL-1, IL-6, TNF). The results showed that in hypertensives AGT gene, TT genotype was 55.
