This paper develops an application and appraisal system for new technologies and projects based on No.1 Military Medical Project. With this system, all application and appraisal work can be performed through network so that the appraisal efficiency is raised and the traditional management of scientific research is infused new energy.

Objective: To study the influence of negative electrets on apoptosis of fibroblast cells and to probe its mechanism. Methods: Fibroblast cell were treated with -300, -500 and -1 000V PTFE electrets for 24, 48 and 72 h, respectively, and the influence of negative electrets on cell apoptosis was studied by means of flow cytometry and transmission electron microscope. Results: Compared with control group, apoptosis cells increased from 0.5% to 10% (some even to 15%) after 24，48 and 72 h action of -300, -500 and -1 000 V electrets. After action of -500 V PTFE electrets for 48-72 h, fibroblast cells showed characteristic morphological features of apoptosis. These features included chromatin aggregation, nuclear and cytoplasmic condensation and partition of cytoplasm and nucleus into membrane bound-vesicles (apoptotic bodies). The effect of negative electrets on apoptosis was in proportion to the time and electric field intensity. Conclusion: Negative electrets can enhance apoptosis of fibroblast cells.

Objective To explore the feasibility and superiority of the simplified partial pressurized tourniquet used in bleeding or injured limbs in battlefield.Methods The tourniquet was composed of the disposable infusion bag,bulb for blood pressure apparatus,pressure gauge and heparin cap.The disposable infusion bag wrapped around the bottom of the cravat took the places of the balloon and the harness.The pressure on the upper and lower limbs were 180mmHg and 200mmHg respectively.Results The low-cost tourniquet,with easily adjustable pressure,was easy to operate and carry.It was efficient in hemostasis and had a low rate for complications.Conclusion The tourniquet can be applied to self and buddy aid,and thus the incidence of shock can be decreased.
