[Distribution characteristics and model establishment of microorganisms in electrokinetic remediation of organic contaminated soil.].

Soil microorganisms would reproduce rapidly and migrate directionally under the applied electric field. In this study, tetradecane-degrading bacteria were added at different locations in soil, and 1 V·cm unidirectional DC electric field was applied to investigate the migration, distribution, and degradation characteristics of target bacteria in soil. The results showed that microorga-nisms migrated to the cathode and anode by electrodialysis and electrophoresis, respectively.

[Pollution assessment in the intertidal zone of Beibu Gulf using multi-biomarker pollution index].

This paper assessed the coastal environmental quality along the Beibu Gulf using a statistical approach, multi-biomarker pollution index (MPI). Samples of clam (Paphia undulata) and sediment were collected at nine sites from the intertidal zone of Beibu Gulf in April 2011. Nine biomarkers of response were measured both in gill and digestive gland in Paphia undulata, and twelve kinds of contaminants were measured in different sediment samples.

[Marine environmental assessment approaches based on biomarker index: a review].

Biomarkers are applied worldwide in marine environmental assessment due to their "early warning" function to chemical pollutants. Several integrative index approaches such as multi-marker pollution index (MPI), integrated biomarker response (IBR), bioeffect assessment index (BAI), biomarker response index (BRI), and health assessment index (HIS), have been developed based on biomarkers. By transforming the complex alterations of biomarkers into a single class or value, these approaches have been so far the useful tools for assessing the environmental quality.

Clinical study on the treatment of premature ejaculation by Uighur medicine gu-jing-mai-si-ha tablet.

Objective: To observe the effect of Uighur medicine gu-jing-mai-si-ha tablet (GJMSHT) for treatment of premature ejaculation (PE) and to explore part of its mechanism.

Methods: The condition of patients was scored by related questionnaire, and the intravaginal ejaculation latency time (IELT) was observed before and after GJMSHT treatment, with the blood levels of nitric oxide (NO) and prostaglandin F2alpha (PGF2alpha) detected in PE patients as well. The results were compared with those in the control group.

[Study on the quantitative change of anthraquinonoids of Rhei in the preparation of dachengqi].

Objective: To study the scientific evidence of the traditional preparation of Dachengqi: "Boiling Aurantii Immaturus and Magnoliae Officinalis first, and then adding Rhei to decoct together. Discarding the dregs, adding Natrii Sulfas into the decoction and drinking the upper solution when the Natrii Sulfas has dissolved completely".

Method: The concentrations of free and combined anthraquinonoids(emodin, rhein, chrysophanol, physcion) in different decoctions were determined with HPLC method respectively.
