Blood coagulation dynamic testing sensor based on electromagnetic vibration.

Rapid detection techniques and methods of blood coagulation have attracted wide attention in academia and the business community in the presence of the increased demands for rapid assessment (point-of-care testing) of patients from surgery, intensive care unit, and other departments. The differential equation of vibration system composed of elastic support and electromagnetic induction devices was set up using the principle of damping vibration and establishing the dynamics model; meanwhile, the harmonic response analysis and vibration fatigue coupling analysis were carried out, the analysis results were optimized, and the experimental device of the electromagnetic induction testing sensor was established. In addition, the experimental device with blood coagulation reagent was assorted to establish the standard point-of-care testing rapid blood coagulation detection curve, and to compare the testing curve with that of the imported point-of-care testing blood coagulation instrument.

[Environmental geochemical baseline of heavy metals in soils of the Ili river basin and pollution evaluation].

Environmental geochemical baseline models of Cu, Zn, Pb, As, Hg were established by standardized method in the ehernozem, chestnut soil, sierozem and saline soil from the Ili river valley region. The theoretical baseline values were calculated. Baseline factor pollution index evaluation method, environmental background value evaluation method and heavy metal cleanliness evaluation method were used to compare soil pollution degrees.

The union of anti-CD34 antibody can improve the performance of drug-eluting stents.

Objectives: The authors investigate whether the combination of anti-CD34 antibody with DES is win-win cooperation.

Background: DES may reduce the risk of restenosis compared to bare-metal stents (BMS), but they were found to inhibit the healing process of intima.

Methods: Fifteen BMS, 17 DES, and 16 combined anti-CD34 antibody and DES were randomly implanted in the coronary arteries of 22 minipigs.

[Monitoring early toxicity of heavy metals including Hg using a HSE-SEAP reporter gene].

Objective: To develop a cellular assay based on heat shock signal pathway and secreted alkaline phosphatase (SEAP) reporter gene for investigating/predicting the early toxicity of heavy metals on HeLa cells in Chinese traditional medicine (TCM).

Method: The pHSE-SEAP plasmid was transfected into HeLa cells to build a HSE-SEAP-HeLa cell model. For validation of the model, the transfected cells were treated by either heating at 42 degrees C for 1 h or incubated with 5 mol x L(-1) CdCl2 for 4 h.
