RESUMO
Based on the clinical characteristics of multiple sclerosis （MS） in traditional Chinese medicine （TCM） and western medicine and literature analysis， this paper aims to formulate the diagnostic criteria of TCM and western medicine for MS. Moreover， the modeling methods of experimental autoimmune encephalomyelitis （EAE）， animals for the modeling， and characteristics of the models were analyzed and summarized， and the consistency between the EAE models and the diagnostic criteria of TCM and western medicine was evaluated. The results showed that animal models had low consistency with the clinical characteristics in TCM （highest consistency 68%） and western medicine （highest consistency 60%）. Pathological models account for the majority of animal models for MS research， but there is a lack of intuitive performance indicators. Thus， it is difficult to comprehensively evaluate the models. The mental state， limb numbness， lack of strength， loss of muscle tone， tremor， and balance disorders of the mice are among the diagnostic criteria in western medicine. In TCM diagnostic criteria， the major symptoms which are reflected in animal behavior， such as physical fatigue， lack of strength， mental fatigue， distinclination to talk， and weak heavy numb limbs， are consistent with the western diagnostic criteria. The minor symptoms， including mental decline， bitter taste in mouth， frequent and urgent urination， fecal incontinence， and aggravated fever， are not well reflected in the models. According to TCM， MS is caused by deficiency of kidney essence and external contraction of pathogen， but no index is available for evaluating the external contraction of pathogen in existing animal models. The key to experimental research on MS is to establish an appropriate animal model based on the clinical pathogenesis and characteristics. However， there is a lack of MS animal model with TCM characteristics for syndrome classification. Therefore， renewed efforts should be made to prepare animal models with both TCM and western medicine characteristics that can be used in both basic experiments and clinical research.
RESUMO
<p><b>OBJECTIVE</b>To explore the clinical effects of locking plates in the treatment of intertrochanteric hip fractures.</p><p><b>METHODS</b>From February 2006 to December 2008,108 patients with intertrochanteric hip fractures treated with locking plate and DHS were retrospective analyzed. Fifty-one patients were treated with locking plates, including 23 males and 28 females, aged 45 to 86 years old (averaged 66.0 years old); and fifty-seven patients were treated with DHS, including 26 males and 31 females,aged 43 to 81 years old (averaged 64.1 years old). The outcome measures collected for statistical analysis on the following aspects: operative time, blood loss, drainage, healing time, complications and Harris scores.</p><p><b>RESULTS</b>One hundred and eight patients were followed up ranging from 8 to 24 months (averaged 12.5 months). In locking plate group, the operative time was (87 +/- 14) minutes; blood loss was (367 +/- 213) ml; drainage was (63 +/- 14) ml; healing time was (11.9 +/- 3.4) weeks; 7 patients had complications; and the Harriss score was (85 +/- 6). While in DHS group, the operative time was (115 +/- 23) minutes; blood loss was (582 +/- 243) ml; drainage was (98 +/- 16) ml; healing time was (12.4 +/- 2.5) weeks; 9 patients had complications; and the Harriss score was (84 +/- 8). There were no significant differences in the healing time, complications and Harris scores between two groups (P > 0.05),but there were significant differences in the operative time,blood loss, drainage between two groups (P < 0.05). Comparing with DHS group, the locking plate group was of shorter operative time, fewer blood loss and drainage.</p><p><b>CONCLUSION</b>Proximal femoral locking plate is simple, minimally invasive,stable fixation with fewer complications, and is an effective method for intertrochanteric hip fractures.</p>
