The article is study about principle of lower extremities on Guides to the Evaluation of Permanent Impairment. We reviewed the latest concept in lower extremities evaluation of GEPI, such as regional impairment, diagnosis based impairment and grade modifier. We also introduced maximum medical improvement and conversion from lower extremities impairment to whole person impairment. To provide advice for construction of disability evaluation system in China.

The article is comparative study about spine and extremities on clause for the identification of the body injured and The classification of the body impairment. We reviewed the terms and provisions about spine and extremities as follows, amputation impairment, function impairment, and amputation impairment combined function impairment. This paper provides a comprehensive access and analysisofthe similarities and differences between the two standards.

The article is study about range of motion on lower extremities on Guides to the Evaluation of Permanent Impairment. We reviewed the latest range of motion concept about lower extremities evaluation of GEPI. We also introduced measurement and procedure of range of motion evaluation. To provide advice for construction of disability evaluation system in China.

Objective The article is to study on the detection of α-helix proteins in post-traumatic epileptogenic focus by FTIR-mapping. Methods Fourier transform infrared spectroscopy-mapping were applied to identifying α-helix by point-by-point scanning in post-traumatic epileptogenic focus sections and to develop FTIR-mapping profiles. Result The high absorbance of α-helix is accord with post-traumatic epilepsy, there are some significant differences between high absorbance and low absorbance. Conclusion α-helix proteins are distributed in post-traumatic epileptogenic focus widely, thus α-helix protein are involved in post-traumatic epilepsy.
