ABSTRACT
The early mortality of spontaneous intracerebral hemorrhage is higher. Hematoma enlargement is the main determinant of early neurological deterioration and poor outcome in patients with intracerebral hemorrhage. The use of non-contrast computed tomography (NCCT) signs to predict hematoma enlargement and poor outcome after cerebral hemorrhage is a current research focus. This article reviews the predictive value of various NCCT signs for hematoma enlargement and poor outcome in patients with acute cerebral hemorrhage, including liquid level, hypodensity, blend sign, swirl sign, black hole sign, satellite sign, and island sign.
ABSTRACT
Objective To investigate the clinical effects of Kangfuxin Solution used together with Baofukangshuan on chronic cervicitis after having been processed cervical LEEP circumcision.Methods Retrospective analysis was made among 176 out-patients diagnosed of chronic cervicitis from November 2007 to January 2009.Of all these patients,90 patients were treated with Kangfuxin Solution and Baofukangshuan after LEEP circumcision(the treatment group),and 86 patients were treated with simple cervical LEEP circumcision(the control group).The wound healing,vaginal discharge,bleeding volume,and side effects were observed in both groups.Results The method in the treatment group significantly reduced the amount of vaginal discharge and the duration,decreased the amount of bleeding and the duration;excluded wound infection and adverse reactions,and facilitated cervical wound recovery.The curative rate(98.89%)in the treatment group was significantly higher as compared to the control group(86.05%)after 8 weeks of the treatment.Conclusion Cervical LEEP circumcision surgery supplemented by Kangfuxin solution and Baofukangshuan therapy has better efficiency than treated by simple cervical LEEP circumcision.
ABSTRACT
An electrogenerated chemiluminescence ( ECL) sensor was fabricated by employing ruthenium complex polymer as ECL signal and ionic liquid as binding reagent and a sensitive ECL method for the determination of heroin was developed. The ECL sensor was prepared by thoroughly mixing ruthenium complex polymer,graphite powder and ionic liquid,which shows good electrochemical and ECL behaviors. The detection limit for tripropylamine (TPA) was one order of magnitude lower than that observed at the paraffin modified carbon paste electrode. ECL intensity of the fabricated sensor was greatly enhanced in the presence of heroin and a sensitive ECL method was proposed for the determination of heroin based on the enhancement ECL. The ECL intensity was linear with the concentration of heroin in the range from 2. 0 ×10~(-9) mol/L to 2. 0×10~(-5) mol/L and the detection limit was 8×10~(-10) mol/L. The ECL sensor exhibited a long-term stability,fine reproducibility with relative standard deviation less than 5% for 5. 0×10~(-9) mol/L heroin in 60 continuous determinations. The developed method allows the detection of heroin in a serum sample with recovery in 94% -101%.
