Objective To evaluate the clinical efficacy of endovascular embolization with detachable balloon, based on the characteristics of traumatic carotid-cavernous fistulae (TCCF), in treating TCCF. Methods The clinical data of 188 patients with TCCF, who had received endovascular embolization with detachable balloon via femoral artery access, were retrospectively analyzed. The risk factors for recurrence were statistically analyzed. Results Of the total 188 patients, complete cure after the first balloon embolization was obtained in 160, certain improvement of clinical symptoms was achieved in 22, and balloon embolization failed in 6, for whom other surgical options had to be carried out. Complications occurred in three patients. Recurrence was seen in 23 patients within the period from one day to 5 years after the treatment, and the recurrent lesion was successfully cured in all patients. Univariate analysis and chi square test or correction chi square test indicated that factors affecting postoperative recurrence were the use of multiple balloons for embolization and the presence of residual fistula after operation (P<0.05), while patient’s sex, age, duration of disease showed no statistically significant correlation with the recurrence (P>0.05). Multivariate logistic regression analysis revealed that the independent factors affecting recurrence included the number of used balloon≥2 (OR=7.80, 95%CI:2.28-26.73,P=0.001) and postoperative residual fistula that was observed immediately after the embolization (OR=10.46, 95%CI:2.99-36.50,P=0.000). Conclusion For the treatment of TCCF, transcatheter embolization with detachable balloon is minimally-invasive, safe and reliable with fewer complications, therefore, this technique should be regarded as the therapy of first choice. The use of multiple balloons and the presence of residual fistula observed immediately after the embolization procedure are the risk factors for recurrence. Other possible risk factors are still to be furtherstudied.

Objective A new mechanical thrombectomy instrument with preliminary clinical application were introduced. Methods Four cases (3 men and one woman; 61-71 years of age, mean age 66) consisting six legs with subacute or chronic occlusion of the femoropopliteal arteries having a course of 75 days to 10 months, were included in this study. All patients were treated with Straub Rotarex System (Straub Rotarex, patent pending. Straub medical, Wangs, Switzerland). Among them 2 cases were caused by atherosclerosis, 1 by emboli and 1 by diabetes mellitus. The lengths of the occluded segments were 3.8-56 cm. Results The thrombi were removed, and the arteries were undergone recanalization. The blood loss was low, amounting to 5-180 ml. Distal emboli formation in 3 legs were treated successfully by thrombsuction or thrombolysis. Conclusion Straub Rotarex System is a new safe and effective mechanical thrombectomy instrument.

ObjectiveTo explore efficacy,durability and possible impacts on life quality of carotid occlusion treatment to carotid cavernous fistula (CCF) patients.MethodsCCF patients since 2001 were retrospectively analyzed,the clinical features,2 weeks post procedure mRS score and ratio of carotid occlusion were recorded.Headache impact test (HIT-6) and Short form health survey(SF-36) were used to assess impact of sequelae in patients' daily life,by phone call,questionnaire and clinic recheck.Results Total 96 cases were studied composed of 81 direct CCF and 15 dural AVF.Thirty-two direct CCF cases underwent carotid occlusion during procedure and many ophthalmologic signs but visual impairment got recovery after 2 weeks,the mRS score less than 2 were revealed.The one year post operation HIT-6 score more than 50 was more likely found in carotid occlusion cases comparing with those preserved carotid artery while the 3 year SF-36 scores of carotid occlusion cases revealed inferior to those with patent artery,especially in body pain,general health and vitality subscales.ConclusionCarotid occlusion seems to be a feasible,effective and durable alternative for CCF treatment,but which could play a negative role on quality of patients' life in the long run.

Background and purpose: Epithelial ovarian carcinoma is the most malignant tumor in female reproductive system because of its resistance to chemotherapy. Fructose-1, 6-bisphosphatase (FBP1) is a rate-limiting enzyme in gluconeogenesis used to catalyze the hydrolysis of fructose-1, 6-bisphosphate to fructose-6-phosphate and inorganic phosphate, thereby inhibiting the effect of glycolysis in tumor cells. This study aimed to investigate the association between the expression of FBP1 and chemosensitivity. Methods: The expression level of FBP1 in ovarian cancer patients was measured by immunohistochemistry. Results: According to the results of immunohistochemistry in 209 ovarian carcinoma specimens, the percentage of positive FBP1 expression was about 49.3% (103/209). Loss of FBP1 was a negative factor of survival (42.6 months vs 62.1 months, P=0.003). Besides, patients who were sensitive to chemotherapy displayed significantly higher scores of FBP1 expression than patients who were resistant to therapy (P=0.007). Conclusion: The rate-limiting enzyme FBP1 in gluconeogenesis can be used as a biomarker for predicting the chemoresistance and prognosis of ovarian cancer patients.

Objective To provide guidance for oral health prevention by investigating oral health status of 480 Lahu people.Methods Oral health status of 480 Lahu people were investigated by trained dental therapists using standard diagnostic criteria and record.Participants were divided into 4 groups according to their age.Results The Lahu People in Linxiang county suffered from severe dental caries and periodontal disease.The caries prevalence rate among children of 5 years old was 78.3％.The rate of calculus among the children of 12 years old was 75％.The prevalence rates of caries and periodontal pockets were 91.7％ and 43.3％ among the adults between 35 and 44 years old.The above data were significantly higher than the results of the Third National Oral Health Survey.The rates of gingival bleeding and periodontal pocket were 51.7％ and 49.2％ among the aged from 65 to 74 years old,which were lower than that of the Third National Oral Health Survey.Among the participants,76％ never brushed teeth and 85％ brushed teeth only once a day in people who brushed teeth regularly.Conclusion Poor status and maintenance of oral health in the Lahu People suggest that education and resources for oral health should be invested.

Objective To evaluate the feasibility,efficacy and complication of early middle cerebral artery(MCA) mechanical recanalization(MER) for treatment of acute ischemic stroke.Methods Seven cases undergone MER of MCA for the treatment of acute cerebral infarct were retrospectively reviewed and analyzed,including the etiology,mechanism,Qureshi grading scale,location and size of infarcts,NIHSS score of pre and post procedure,endovascular technique and complications.Referring to the literature,the indications of MCA recanalization were further identified.Results A total of 7 cases with mean age of 48 yrs were reviewed,which included 3 cases of atherosclerotic thrombosis and 4 embolic cases with pre NIHSS score ranging from 3 to 22.Mechanical recanalization succeeded in 6 cases,but 2 cases of cardiogenic embolism died of intrac ranial hemorrhage postoperatively.Favorable clinical outcomes were achieved in 4 cases whereas 1 deteriorated.Overall complications seemed to be consistent with literatures reviewed.Conclusions Early MER of MCA may benefit to a certain subset of acute ischemia stroke patients,however,embolic cases,elder patients and those with severe neurologic deficits are often accompanied by higher complications and unfavorable outcome.
