[Clinical analysis of acute cerebral infarction by Dengzhanhua injection and Xiongqin injection combined with Xuesaitong treatment].

Objective: To study the clinical effect of Dengzhanhua injection and Xiongqin injection combined with Xuesaitong to treat the elderly patients with acute cerebral infarction.

Methods: From March 2012 to March 2013,140 patients with acute cerebral infarction elderly patients were treated, as research subjects were randomly divided into two groups, the observation group and the control group,70 cases in each group. The control group were treated using Xuesaitong;The observation group using Dengzhanhua injection and Xiongqin injection combined with Xuesaitong.

Extrinsic fiber-optic Fabry-Perot interferometer sensor for refractive index measurement of optical glass.

A simple fiber-optic sensor based on Fabry-Perot interference for refractive index measurement of optical glass is investigated both theoretically and experimentally. A broadband light source is coupled into an extrinsic fiber Fabry-Perot cavity formed by the surfaces of a sensing fiber end and the measured sample. The interference signals from the cavity are reflected back into the same fiber.

Rapid determination of surfactant critical micelle concentration in aqueous solutions using fiber-optic refractive index sensing.

We describe a simple and rapid method for determining the critical micelle concentration (CMC) of surfactants from fiber-optic measurements of refractive index. The refractive index of an aqueous surfactant solution was monitored as the surfactant concentration was increased using an automated dispensing system. On reaching the surfactant's CMC value, an abrupt change was observed in the rate of increase of the refractive index with increasing concentration.
