A system for developing and implementing empirically derived algorithms to generate decision rules to determine participant noncompliance and fraud with research protocols in clinical trials allows for the identification of complex patterns of variables that detect or predict participant noncompliance and fraud with research protocol, including performance and enrollment goals, in the clinical trial. The data may be used to overall predict the performance of any participant in a clinical trial, allowing selection of participants that tend to produce useful, high-quality results. The present invention can also be used to monitor participant compliance with the research protocol and goals to determine preferred actions to be performed. Optionally, the invention may provide a spectrum of noncompliance, from minor noncompliance needing only corrective feedback, to significant noncompliance requiring participant removal from the clinical trial or from future clinical trials. The algorithms and decision rules can also be domain-specific, such as detecting non-compliance or fraud among subjects in a cardiovascular drug trial, or demographically specific, such as taking into account gender, age or location, which provides for algorithms and decision rules to be optimized for the specific sample of participants being studied.

The present invention relates to the technical field for the medical and biological material. In the recent ten years, researchers all over the world have proved that it is possible that the nerve frame can replace the antilogous transplantation in nerve defect repairing. But the chitosan tube of a single element has poor elastic property, which is easy to fracture; therefore the nerve stump is hard to be fixed in the tube. The present invention provides a preparation method for the chitosan nerve tube, which has great stretching intensity, long time maintenance in the body and capacity of biodegradation and absorption. In the present invention, the collagen protein and the acid solution of the chitosan are mixed into a composite according to a proper volume ratio. The composite liquid receives layers solidification on the model. The animal test and the clinical research discover that the present invention is capable of bridge joint between the nerve defect ends; the stretching intensity is strong and maintenance in the body is long; reproduction of the nerve is promoted. The technique of the present invention is simple with low cost, which can replace the traditional nerve joint method. The present invention has good application prospect in clinical treatment for the peripheral nerve defect.
