Objective The aim of this paper is to study the hemostasis and security of soluble hemostatic gauze in the rabbit liver hemorrhage model.Methods After making the rabbit liver hemorrhage model, the control group used sterile gauze to stop bleeding, the positive control group used TISTAT to stop bleeding, the test group used soluble hemostatic gauze to stop bleeding. Hemostasis, blood loss and animal clinical symptoms were measured. Liver and kidney parameters, along with histopathology were recorded and analyzed. Transmission electron microscopy examination was also done. Results The blood loss is cut back and hemostasis is shortened in the test group. Other tests have no difference with the control group.Conclusion No toxic effects on rabbit are found in the test group. The hemostatic effects have no difference with positive control group.

Objective Analyzing the performance of microbial barrier of needleless positive pressure closed connectors. Methods Three kinds of brand needleless positive pressure closed connectors were chosen to do the access of microorganisms test. Results Positive results were detected in the three experimental groups. Conclusions So far, lots of the connectors are not qualified strictly on the market, some improvement is required in the structure design and process.

This review introduces a brief description on the featured properties of polyvinyl alcohol based on hydrogel dressings. During past ten years many new artificial polymeric dressings have been developed, which meet requirements of wound healing. This review mainly focuses on one representative of ideal polymeric wound dressing membranes, polyvinyl alcohol based hydrogel dressings. But as the hydrogels with single component have low mechanical strength, recent trends have offered composite hydrogel membranes to achieve the ideal wound dressing requirements.
