Objective To investigate the influence of combined thrombolysis therapy on clinical effects for short -and long -term of patients with acute cerebral infarction caused by sudden occlusion of anterior and posterior circulation.Methods 75 patients with cerebral infarction caused by sudden occlusion of anterior and posterior circulation were chosen and divided into A group (46 patients)with sudden occlusion of anterior circulation and B group (29 patients)with sudden occlusion of posterior circulation by comprehensive therapy for intra -arterial thrombolysis combined with mechanical crushing and dilation.The recanalization rate,the excellent and good rate of ADL -Barthel score,NIHSS score and GCS score before and after treatment,intracranial hemorrhage rate and mortality rate of two groups were compared.Results The recanalization rates of A group and B group were 50.00%(23 /46), 89.66%(26 /29).After treatment,the excellent and good rates of ADL -Barthel score of A group and B group were 58.70%(27 /46),62.07%(18 /29).The recanalization rate of B group was significantly higher than A group(χ2 =7.44,P <0.05).There was no significant difference in the excellent and good rate of ADL -Barthel score after treatment between the two groups(χ2 =1.21,P >0.05).After treatment,the NIHSS scores of A group and B group were (8.66 ±2.48)points,(8.72 ±2.51 )points,the GCS scores of A group and B group were (12.89 ± 3.61)points,(13.10 ±3.72)points.There were no significant differences in NIHSS score and GCS score after treatment between the two groups(t =1.47,1.52,all P >0.05).After treatment,the intracranial hemorrhage rate of B group was significantly lower than A group (χ2 =8.16,P <0.05 ).There was no significant difference in the mortality rate between the two groups(χ2 =0.98,P >0.05).Conclusion Compared with acute cerebral infarction caused by sudden occlusion of anterior circulation,combined thrombolysis therapy in treatment of patients with sudden occlusion of posterior circulation has advantages including higher recanalization rate and lower risk of intracranial hemorrhage.

Objective To analyze the efficacy and safety of suprapubic arc sling (SPARC) and transobturater vaginal tape (TOT) for female stress urinary incontinence (SUI). Methods A retrospective study was conducted on 275 women ( 139 in TOT group and 136 in SPARC group) in our institute from September 2008 to January 2011.We had compared the complications of the two groups.All the patient's ICI-Q-SF scores and PISQ-12 scores were collected.We compared the pre- and post-operative Qmax and PVR to find out if SPARC or TOT tap cause bladder outlet obstruction (BOO). Results The operative time was 25.1 ± 3.3 min for TOT and 34.8 ± 5.6 min for SPARC.There was statistical difference between the two groups in the aspects of operative time (P =0.00).The improvements of average symptom and QOL scores in patients undergoing TOT and SPARC were statistically significant (P =0.00).The improvements of the PISQ-12 scores in the two groups were statistically significant (P ＜0.05 ) as well.There was no significant difference (P ＞ 0.05 ) in the total cure rate of TOT and SPARC.The complications post SPARC and TOT were low.In the TOT group,the Qmax changed from 30.2 ± 8.7 ml/s per-operatively to 24.9 ± 8.6 ml/s post-operatively in a week.PVR changed from 1.6 ± 4.2 ml pre-operatively to 3.2 ± 6.5 ml post-operatively in a week.In the SPARC group,the Qmax changed from 31.7 ±9.4 ml/s pre-operatively to 26.9 ± 8.9 ml/s post-operatively in a week.PVR changed from 1.4 ± 3.7 ml pre-operatively to 3.5 ± 6.3 ml postoperatively in a week.All the changes were significant ( P ＜ 0.05 ).And in the SPARC group,the Qmax changed from 31.2 ± 10.0 ml/s pre-operatively to 26.2 ± 9.1 ml/s post-operatively; the PVR changed from 1.8 ± 3.2 ml pre-operatively to 4.7 ± 8.8 ml post-operatively (P ＜ 0.05). Conclusions Both the TOT sling and the SPARC sling have high cure rates for SUI.But the retropubic sling may lead to BOO and other complications,so the transobturate sling is a better treatment option for SUI.

OBJECTIVE: To provide the anatomic data for the correlated otologic microsurgery by the microdissection of temporal bone through facial recess approach. METHOD: Sixteen human temporal bones of eight adult cadaveric heads were dissected under surgical microscope through facial recess approach, and the relative anatomic structures were observed and measured, such as the bony entrance of facial recess approach, facial nerve, stapes, round window, round window niche, pyramidal eminence, cochleariform process, etc. The data were analyzed statistically. RESULT: The width of the bony entrance of facial recess approach was (2.94 +/- 0.32) mm, the height was (8.83 +/- 0.84) mm, the depth was (3.51 +/- 0.17) mm. The distances from stapes to tympanic segment of facial nerve, mastoid segment of facial nerve, round window, cochleariform process and anterior ligament of malleus were (1.38 +/- 0.21) mm, (6.94 +/- 0.47) mm, (3.60 +/- 0.55)mm, (2.23 +/- 0.33)mm, (4.93 +/- 0.61) mm, respectively. The distances from pyramidal eminence to tympanic segment of facial nerve, mastoid segment of facial nerve, round window, round window niche and cochleariform process were (1.05 +/- 0.09) mm, (5.63 +/- 0.41) mm, (3.01 +/- 0.34) mm, (3.29 +/- 0.44) mm, (4.13 +/- 0.51) mm, respectively. The distances from round window to cochleariform process and tympanic segment of facial nerve were (5.11 +/- 0.61) mm and (3.97 +/- 0.61) mm. The distances from round window niche to tympanic segment of facial nerve and mastoid segment of facial nerve were (4.13 +/- 0.38) mm and (7.28 +/- 0.29) mm. CONCLUSION The facial recess approach played an important role in modern otologic microsurgery. The position of anatomical structure was constant relatively, including short crus of incus, stapes, pyramidal eminence and cochleariform process, etc. These could be used as reference marks for otologic microsurgery.

Objective To investigate and analyze the clinical effect of neural interventional treatment in cerebrovascu-lar diseases. Methods 50 patients with cerebrovascular disease who hospitalized in our department from May 2010 to May 2014 were selected. According to their willingness, they were divided into the observation group and the control group. They were given the satisfaction investigation after operation, which included patients' symptoms (physical activity, language, consciousness and headache), body condition (muscle tension classification) and satisfaction of related compli-cations (hemorrhage of digestive tract, infection of lung and heart conditions etc.) remission. Results DSA showed that carotid and vertebral artery stenosis of the observation group (with more than 75% reduction) were superior to those of the control group (with about 45%reduction). 1 case in the control group recurred, and the observation group had lower cerebral vascular recurrence rate. Postoperative satisfaction results showed that satisfaction of the observation group (92.68%) was higher than that of the control group (44.44%) and the neural interventional treatment was more satisfying for patients with cerebrovascular disease (P<0.05). Conclusion Neural interventional therapy is not only remarkably curative, but also helpful for the recovery and life quality improvement of patients. It should be promoted in clinic.
