Objective To investigate the effects of DanzhiⅠ on rats acute skin trauma model.Method Perforate back of the rats was made with special puncher to establish acute trauma model.Wound surface was applied with Danzhi Ⅰ and the healing process was observed.Result Danzhi Ⅰ significantly shrinked the rim of raw surface and shorten the time of healing.The number of completely healed rats increased obviously.Conclusion Danzhi Ⅰ can significantly accelerate the healing of acute skin trauma of rats.

Objective The purpose of this paper is to study the variations of the bone conduction hearing in the patients with chronic suppurative otitis media complicated by bone conduction deterioration after tympanoplasty and to analyze the relative factors. Methods In 54 cases (61 ears) of decreased bone conduction thresholds associat-ed with chronic suppurative otitis media, reviewed retrospectively were the data before the operation and during the follow-ups from 3 to 27 months. The bone conduction thresholds at 0. 5,1, 2 and 4 kHz were studied in relation to the courses of disease, the complications of cholesteatoma, the operation procedures and the reconstructions of os-sicular chains before and after surgeries. Results Before operation the most obvious hearing loss of bone conduction was found at 4 kHz in 61 ears, while after operation the average bone conduction hearing at the 4 frequencies was improved at different degrees with the most at 2 k Hz. Thirty-two of 61 cases (52.50%) were found to have their hearing improved at least by more than 10 dE at two frequencies without any deterioration at the 4 frequencies. Con-clusion The factors of the duration of disease and complications of cholesteatoma are obviously not related to the improvement of hearing after operation. A patient with reconstruction of ossicular chain is markedly superior to one without the reconstruction in improvement of hearing. When the auditory ossicular chains and functions of the oval and/or round windows are damaged, the bone conduction hearing can be affected accordingly. However the hearing of some cases will be improved after tympanoplasty. Also, the possible improvement is also related to different sur-geries in treating patients with middle ear infections.

OBJECTIVE: To study the clinical effect of Treatment of blow-out fracture of medial orbital wall with nasoseptal cartilage under nasal endoscope. METHOD: Under a nasal endoscope, the fracture and the prolapsed orbital contents were reduced to the orbit, and then an autogenous nasoseptal cartilage was grafted into the orbital defect. The variations in the visual acuity, diplopia, enophthalmos degree and eyeball position were detected preoperatively and postoperatively. RESULT: During the follow up of three months to four years after operation, all the 28 cases showed neither loss nor distinct descent of visual acuity. The postoperative mean enophthalmos degree (1.5 +/- 0.6) mm was lower than the preoperation one(3.6 +/- 1.1) mm (P<0.05). Diplopia disappeared completely of 25 cases during 3 month after operation,while it appeared in the primary position of 2 cases. The eye movement was normal of 26 cases after operation t, and the abduction was slightly limited of 2 cases, but which was better than be for). Any displacement of filling material, infection, rejection reaction were not found of all the 28 cases. CONCLUSION The medial orbital blow out fracture with nasal endoscope has many advantages, such as short operative route, clear surgical visual field, simple performance, light injury and no scars, and the effect of which will be really certain in the operative practice.

Objective To study the risk factors for progressive cardiogenic stroke (CS).Methods Seventy-one acute ischemic stroke patients admitted to our hospital from 2008-08-01 to 2014-12-31 were divided into progressive CS group (n=14) and non-progressive CS group (n=57).The NIHSS was used to assess the neurologic deficit when the patients were admitted and 30 days after the stroke onset.Their clinical data were retrospectively analyzed.The risk factors for progressive CS were analyzed by univariate logistic regression analysis and multivariate logistic regression analysis respectively,their critical thresholds were analyzed according to the ROC curve.Results The NIHSS improvent of the progressive CS group was significantly less than that of the non-progressive CS group (P＜0.01).The age was significantly older,the incidence of right-side infarction and the serum level of D-dimer were significantly higher while the serum level of glutamic pyruvic transaminase was significantly lower in progressive CS group than in non-progressive CS group (77.29±8.87 years vs 71.44±9.51 years,P=0.041;71.4％ vs 33.3％,P=0.009;2.82 mg/L vs 0.91 mg/L,P=0.048;13.79±4.44 U/L vs 21.98±17.34 U/L,P=0.002).Lo gistic regression analysis showed a significant difference in age,right-side infarction and serum D-dimer level between the two groups (P=0.030,P=0.007,P=0.025).The area under the ROC curve revealed that age ＞ 70.75 years and serum D-dimer level ＞1.23 mg/L were the risk factors for progressive CS.Conclusion Age,right-side infarction and serum D-dimer level are the risk factors for progressive CS and can thus be used as predictors of progressive CS.
