Objective To develop the clinical application and the method for functional repair in fa- cial nerve defect in parotideetomy of parotid carainoma.Methods Defect of facial nerve in parotidectomy was repaired by transplantation of sternocleidomastoid muscle-great auricular nerve flap with anastomosis of great auricular nerve-facial nerve under microscope.Results Eight eases of facial nerve defect in parotid carcinoma were repaired by this method.The facial nerve function almost recovered and access to normal dur- ing 3 to 6 month after operation in this series.6 of 8 patients achieved a gradeⅡ,2 of 8 patients achieved a gradeⅢ.Conclusion Reconstruction of facial nerve defect using sternocleidomastoid muscle-great auricu- lar nerve flap can provide better blood supply for the plerosis and regeneration of nerve.The nerve flap also ac- celerate the functional recovery after nerve grafting.

Objective To evaluate the relationship between carotid artery plagues and the clinical risk factors in patients with diabetes mellitus type 2 by observing the ultrasonic characteristics of carotid atherosclerosis plagues.Methods The ultrasound results of carotid arteries in 665 patients with diabetes mellitus type 2 from January 2009 to December 2011 in Beijing Amery General Hospital were retrospectively analyzed.The location and quantity of carotid atherosclerotic plaques were observed .The relationship between the occurrence and risk factors of diabetes such as hypertension ,family history of diabetes and age were analyzed.Single factor and multi-factor analysis were applied for the related risk factors .Results The ultrasonography showed 405 cases of carotid artery plaques.Most carotid artery plaques were located in the posterior wall of carotid sinus and were hyperechoic ,hypoechoic or isoechoic.The single factor analysis showed hypertension,family history of diabetes and age are risk factors of carotid atherosclerosis (χ2 =42.322,9.682 and 140.658,all P<0.01).Multi-factor logistic regression analysis showed age was an independent risk factor of carotid atherosclerosis in patients with diabetes mellitus type 2.The risk factors scores of patients who were less than 45 years,45-65 years and over 65 years of age were (3.50 ±1.16)scores,(3.46 ±0. 92)scores and (3.21 ±0.88)scores,and the difference was statistically significant (F=5.781,P<0.001). There were significant differences between risk factors scores of different age groups ( t =2.084,2.002, 3.786,3.474,2.877 and 2.504,all P<0.05).In patients more than 65 years of age,the risk of atherosclerosis plaques is 28.732 times higher than that of patients less than 45 years of age.After controlling the age factor,the possibility of atherosclerosis plaque increased 1.201 times for each additional one point of score. Conclusions Most carotid artery plaques in patients with diabetes mellitus type 2 are located in the posterior wall of carotid sinus and are hyperechoic ,hypoechoic or isoechoic.Age is an independent risk factor for the formation of carotid plaque.Patients more than 45 years of age should undergo early intervention to avoid the occurrence of major vascular complications .

Objective To assess the influencing factors of the progression of carotid atherosclerotic stenosis using color Doppler flow imaging (CDFI). Methods From January 2009 to December 2014, a total of data 279 consecutive patients first assessed by CDFI as moderate stenosis of carotid atherosclerosis (stenosis rate 50 -69%)and regularly reexamined with CDFI at 12,24 and 36 months after initial examination were enrolled retrospectively. The residual diameter of vascular lesions and the changes of hemodynamic parameters were documented,and they were divided into either a progression group (n = 40)or a non-progression group (n = 239,and the non-progression group was divided into steady group[n = 210]and improved group [n = 29])according to whether the degree of stenosis progressed into severe stenosis (stenosis rate 70 -99%)or occlusion. The effects of the risk factors for common cerebrovascular disease and taking lipid lowering drugs (atorvastatin 20 mg/ d)on stenosis progression were compared in patients between the 2 groups. There were significant differences in hypertension,smoking and the regular use of atorvastatin . The effects of those factors on the progression of carotid stenosis were compared further through Logistic regression analysis. Results The residual vascular diameters of stenosis at 24,and 36 months were reduced obviously in the progression group compared with those of the non-progression group. There was significant difference (all P < 0. 05),and both the stenotic sites and distal peak systolic flow velocity ratio were significantly higher than those of the steady group and improved group (all P < 0. 05). Among the risk factors for cerebrovascular disease,hypertension (OR,2. 686,95% CI 1. 120 -6. 442,P = 0. 027)and smoking (OR,2. 265,95% CI 1. 081 -4. 746,P = 0. 030)were the major risk factors for affecting the progression of carotid stenosis. Regularly taking atorvastatin was a protective factor of delaying the progression of carotid stenosis (OR,0. 383,95% CI 0. 178 -0. 827,P = 0. 015). Conclusions CDFI may objectively evaluate the progression of carotid stenosis. Smoking and hypertension are the independent risk factors for affecting the progression of carotid stenosis,and regularly taking atorvastatin contributes to delay the progression of carotid stenosis.
