Advance in Clinical Evaluation Methods of Facial Paralysis(review) / 中国康复理论与实践

The clinical evaluation methods of facial paralysis can be divided into functional evaluation scales,neuro-electrophysiologi-cal tests and computer evaluation systems.The commonly used function evaluation scales include House-Brackmann Grading Scale(HB-GS),Burres-Fisch Facial Nerve Scoring System,Nottingham System,Sunnybrook facial grading System(SFGS),Degree of Facial Nerve Paralysis Hierarchical Scale,Facial Disability Index(FDI)and Facial Clinimetric Evaluation(FaCE)Scale,etc.Neuro-electrophysiological tests mainly consist of facial electromyography (EMG), electroneurography (ENoG), blink reflex (BR), and neural excitatory test (NET), etc.The computer evaluation system based on the sensor is mainly divided into the computer evaluation system based on infrared thermal image technology and the computer evaluation system based on biomedicine image recognition.This article briefly summarized the existing methods of facial paralysis evaluation in terms of sensitivity,stability,accuracy,ease of operation and economics.

[Prokaryotic expression and purification of a tandem repeat of ovarian cancer antigen CA125 and preparation of its antiserum].

AIM: To establish a prokaryotic expression system of the tandem repeat of CA125 (CA125R), express and purify the recombinant CA125R protein, prepare its antiserum. METHODS: The full gene sequence of one tandem repeat of CA125 was synthesized and cloned into pET-32a(+) to construct a prokaryotic expression vector of the CA125R protein (pET-CA125R). The pET-CA125R was transformed into E.coli BL21 (DE3) and the soluble expression conditions were optimized; the pure recombinant CA125R protein was prepared by affinity Ni-NTA chromatography and identified by Western blotting. A rabbit was immunized with the pure recombinant CA125R protein to prepare its antiserum. RESULTS: The prokaryotic expression vector of CA125R was successfully constructed. The optimal soluble induction expression conditions were 0.5 mmol/L isopropyl ß-D-1-thiogalactopyranoside (IPTG) at 15DegreesCelsius for 6 h. Western blotting confirmed the pure CA125R recombinant protein of high purity. The prepared antiserum specifically recognized recombinant CA125R protein and natural CA125 glycoprotein. CONCLUSION: We successfully established the efficient prokaryotic expression system of the CA125R, and prepared the recombinant CA125R protein of high purity and its antiserum.

One Case of Traumatic Pericallosal Artery Aneurysm: A Case Report

Traumatic aneurysm is known to be very rare vascular disease. The authors experienced one case of traumatic aneurysm that occured on pericallosal artery after closed head injury. Traumatic aneurysm was suspected by enlarged traumatic ICH on the corpus callosum in brain CT scan and presence of signal voiding at the center of the hematoma in brain MRI scan and then confirmed by transfermoral carotid angiography. Clipped neck of this traumatic aneurysm successfully via interhemispheric approach, we report a case of traumatic pericallosal artery aneurysm with review of literatures.
