[Therapeutic effects of cannulated compression screws for treating femoral neck fractures].

Objective: To explore the relevant factor of cannulated compression screws in treating femoral neck fractures.

Methods: From January 2004 to January 2011, 190 patients with femoral neck fractures treated by cannulated compression screws were analyzed retrospectively. In all of the 190 cases, there were 104 males and 86 females with an average of 65 years (ranged, 21 to 83 years).

[Surveillance of schistosomiasis in Hubei section of the Three Gorge Reservoir areas, 2007 - 2009].

The source of infection of schistosomiasis and snail situation in Hubei section of the Three Gorge Reservoir areas from 2007 to 2009 were investigated by combined epidemiological, immunological and field survey. The results showed that there were no local residents and livestock infected with shchistosome, and no Oncomelania snails were found, but 4 cases of imported patients with chronic schistosomiasis were checked out. It is suggested that the surveillance and intervention should be strengthened pointing to the risk of schistosomiasis transmission in the Three Gorge Reservoir areas, so as to prevent schistosomiasis being endemic in these areas.

[Determination of the allergic impurities in the parenteral injection of Chinese traditional medicines containing Salvia miltiorrhiza].

The residual protein mixture (the content is 4%, approximately), called Salvia miltiorrhiza antigen, was extracted from the Salvia miltiorrhiza cruel materials by mimicking the alcohol-deposit extracts process. Both rabbits and guinea pigs sensitized by Salvia miltiorrhiza could produce specified antibodies. Large molecular antigenic impurities were extracted from the Danshen injection and Xiangdan injection using the centrifugal filtering method.
