To study an improved translabyrithine approach, twenty adult cadaver heads (40 sides) fixed with formalin were dissected by mimicking translabyrithine method under light microscope ,and measurements were performed . The results showed that the rate of meeting with mastoid emissary was 33/40(82. 50%). The distance between the middle part of sigrnoid and the vertical part of facial nerve was 7. 22 ?1.95 mm. The width of the middle part of sigmoid was 10. 5 ? 0. 79mm, the left side was 8. 89 ? 1. 03mm, and the right side was 9. 88 ?2.14mm. The height of jugular bulb was 8. 08?3. 46mm,the left side was 6. 78 ? 3. 17mm,and the right side was 9. 07?3. 04mm. The distance between the highest point of jugular bulb and the base of internal acoustic meatus was 4. 54 ? 2. 81 mm, the left side was 5. 93?3. 12mm, and the right side was 2. 65?1. 87 mm. The distance between the inferior margin of internal acoustic meatus aperture and superrior petrosal sinus was 5. 09?1. 29mm . The diameter of superrior petrosal sinus was 1. 43?0. 08 mm. There were two types of superrior petrosal sinus entering to the sigmoid (or transverse sinus). The angle between superrior petrosal sinus and sigmoid was 52. 17 ?6. 93?. The results suggest that the improved translabyrithine approach can give enough vision for cerebellopontine angle operation.

In order to verify the dependability of 3D data, twenty-four temporal bones of adult head specimen fixed with formaldehyde were scanned by multi-slice helical CT. The technique of shade surface display and volume rendering were used in reconstruction. The 3D data of the surface structure of temporal bone were compared with anatomical specimens. The result showed that the new type CT has more rapid speed in 3D reconstruction and clearer imaging. The technique of shade surface display and volume rendering can give very clear structure of temporal bone. The 3D data makes no difference with anatomical measurement (no statistic difference). It is suggested that the 3d data can instruct the clinic directly.

Objective To observe the effects of different models of rehabilitation education on stroke rehabilitation. Methods There were 35 stroke patients in group Ⅰ，40 patients in group Ⅱ. All the patients received the same rehabilitation treatment, but different model of rehabilitation education. They were evaluated with Functional Independence Measure (FIM) before and after treatment, and the incidence of complications were investigated. Results The FIM grade in all patients increased significantly after treatment (P<0.05), and increased more in the group Ⅱ (P<0.05). The incidence of shoulder pain/ shoulder subluxation, edema in hemiplegic extremity, muscle atrophy were a lower in the group Ⅱ than that in the groupⅠ (P<0.05). Conclusion Improving the model of rehabilitation education can improve the efficacy of stroke rehabilitation.

Objective To observe the effect of rehabilitation education on upper-limb motor function in stroke patients. Methods 40stroke patients were divided randomly into treatment group and control group. The treatment group (n=20) accepted rehabilitation and rehabilitationeducation, and control group (n=20) accepted rehabilitation only. They were assessed with Modified Ashworth Scale (MAS),Fugl-Meyer Assessment (FMA) of upper-limb and Barthel Index (BI) before and after treatment. Results The scores of FMA and BI improvedin both groups after treatment (P<0.01), but the score of MAS improved only in the treatment group (P<0.01). The scores of FMA,BI and MAS improved more in the treatment group than in the control group (P<0.01). Conclusion Rehabilitation education plays an importantrole in motor function rehabilitation after stroke.

To improve efficiency and quality of the laboratory animal in military research institutes,we designed an information management system for which employs advanced technology and provides convenience.Its functions,and operating methods and else are introduced so as to provide reference for elevation level of the scientific research management.

Objective To investigate the underlying neural mechanism of left hemiparalexia and left hemialexia in reading Chinese characters. Methods A patient with reading disorders caused by brain infarctions at the left ventralis medialis occipitotemporal lobe and the splenium of the corpus callosum was studied. A series of neuropsychological tests, such as reading Chinese characters presented in the central foveal field or in the left and right half of the foveal field, were conducted with the patient, and neuroimaging techniques including high spatial resolution 3D-MRI and diffusion tensor tractography (DTT) were used to examine whether or not there were lesions of the neural pathway. Results The patient showed left hemiparalexia, which was characterized by making substitution or omission mistakes, mostly in the left parts of Chinese characters, and also left hemialexia(alexia for characters presented in left visual field). 3D-MRI demonstrated infarctions in the left ventral mesial occipitotemporal area and in the left side of the splenium of the corpus callosum. The left lateral mid-fusiform cortex, which has been identified as the visual word form area(VWFA), was almost intact. DTT indicated the major forceps fibers running through the splenium were all disconnected due to the infarction of the left splenium. Conclusion As a result of disruption of the splemium-major forceps pathway, visual character information in the left visual field which is initially projected to the right occipital cortex cannot be transferred from the right visual cortex to the left VWFA. This mechanism of left hemiparalexia and left hemialexia in reading Chinese characters is similar to that in reading English words.

Objective: To observe antipyretic, diuresis, anti inflammatory and antisepsis effects of Qinglin Granules. (Herba Polygoni Avicularis, Herba Dianthi, Caulis Aristolochiae Manshuriensis, Semen Plantaginis, Fructus Gardeniae, etc.) Methods: The model of pyretic rats induced by yeast was used to prove antipyretic action. The diuresis action was observed by the test. The anti inflammatory effect was observed by pettitoes swelling in rats and auricle swelling in mice. The paper diffuse methods were used to confirm the antisepsis effect. Results: Qinglin Granules not only had the obvious effect of relieving fever and increasing the amount of urine, but also had the strong inhibition on the two kinds of inflammatory models, moreover it can widen the diameter of the antisepsis ring which showed it had the inhibition on cdibacillus, pseudomonas, aeruginosa, bacillus gasoformans, staphylococcus aureus and gonococcic. Conclusion: Qinglin Granules have the obvious antipyretic, diuresis, anti inflammatory and antisepsis effects.

Objective:To investigate clinical application of preoperative "second eye" ultrosound guided orientation in non-palpable breast lesions surgery.Methods:100 patients were involved in the present study, with 136 impalpable breast lesions. Patients were divided into treatment group and control group by using random number table method. Patients of the control group were operated according to the preoperative ultrasonic location alone, while lesions of patients from the treatment group were located not only by preoperative surface location, but also by the "second eye" ultrasonic examination performed by surgeons. Volume of resected specimen and the operation time and the average length of incision were observed and compared between the two groups.Results:All lesions were completely resected. The average operation time of the treatment and control groups was 20 minutes vs 28 minutes ( P<0.05) , the average volume of resected specimens was 3.0 ml vs 4.1 ml ( P<0.05) , and the average length of incision was 25 mm vs 30 mm ( P=0.21) . Conclusions:It is an accurate, safe and effective method to remove clinical non-palpable breast lesions by the "second eye" ultrasound operated immediately before the surgery. It can obviously shorten the operation time, precisely remove the specimen, and reduce damage to normal tissues. In clinical practice, breast ultrasonic characteristics are recommended to be mastered by surgeons so that it could be helpful to the surgery.
