Objective To establish virtual three-dimensional instrument and cerebral aneurysm models by using three-dimensional moulding software,and to explore the effect of the models in interventional preoperative simulation.Methods The virtual individual models including cerebral arteries and aneurysms were established by using the three-dimensional moulding software of 3D Studio MAX R3 based on standard virtual cerebral aneurysm models and individual DSA image.The virtual catheter,guide wire,stent and coil were also established.The study of interventional preoperative simulation was run in personal computer,and included 3 clinical cases.Results The simulation results of the working angle and the moulding angle of the head of catheter and guide wire in 3 cases were identical with that of operation results. The simulation results of the requirement of number and size of coil in 1 case of anterior communicating aneurysm and 1 case of posterior communicating aneurysm were identical with that of operation results.The simulation results of coil for aneurysmal shape in 1 case of giant internal carotid artery aneurysm were more than 2 three-dimensional coils with size of 3mm?3 cm from the operation results,and the position of the second coil in aneurysmal neck was adjusted according to the results of real-time simulation.The results of retrospective simulation of operation procedure indicated that the simulation methods for regular and small aneurysms could become a routine simulation means but more simulation experience was needed to build up for the giant aneurysms.Conclusions The virtual three-dimensional instrument and cerebral aneurysm models established by the general software provided a new study method for neuro-interventional preoperative simulation,and it played an important guidance role in developing neuro- interventional operation.

In vivo fast cyclic voltammetry (FCV) was used to investigate dopamine (DA) release from amygdala (Amy) of female rats in different phases of estrus cycle, ovaricectomized (OVX) rats and male rats. Tyrosine hydroxylase (TH) immunohistochemistry was employed to measure the numbers of immunoreactive neurons in ventral tegmental area (VTA) of midbrain in the rats. We also observed the effect of intracerebroventricular injection of phytoestrogen-soy isoflavones on DA release from the Amy. The results are as follows: DA release from the Amy of proestrus female rats was apparently higher than that in estrus, metaestrus, diestrus female rats and OVX rats. Amy DA release and the numbers of the TH immunoreactive neurons in VTA showed a significant sex difference. DA release from Amy of female and OVX rats increased significantly within 5 min after i.c.v injection of soy isoflavones, which elicited no effects in male rats. The above-mentioned results suggest that endogenous estrogen may play an important role in regulating the activity of DA neurons in mid-limbic systems, and that soy isoflavones exert an estrogen-like effect on the dopaminergic systems in the Amy.

Objective To demonstrate the effect of comprehensive treatment under nasal endoscopy for epistaxis. Methods The bleeding sites of 92 patients were defined by nasal endoscopic examination. Epistaxis was cured by single pole or bipolar coagulation, combined with micro packing and systemic treatment. The bleeding sites and effect were studied retrospectively. Results The hemorrhagic foci were found in the following sites: 60.87%(56/92) in Little area, 13.04%(12/92) in the middle and back of nasal septum, 10.87% (10/92) in olfactory sulcus, 8.70% (8/92) in middle turbinate , 3.26% (3/92) at the top of inferior meatus, 2.17% (2/92) at the top of nasal cavity, 1.09% (1/92) at unknown part at the back of nasal cavity. Epistaxis was successfully controlled by once nasal endoscopic examation and hemostasis in 86 of 92 patients. While in 5 of 92 patients, epistaxis was cured by twice nasal endoscopic examation and hemostasis. Endoscopicligation of the sphenopalatineartery was performed in 1 patient with unknown posteriorepistaxis. In 92 patients,15 cases were given micro packing combined with systemic treatment. All the patients were cured and were followed up for 3 months without recurrence and the cure rate was 100.00%. Conclusions The major bleeding site is Little area. Single pole or bipolar coagulation, combined with micro packing and systemic treatment under nasal endoscope is effective for epistaxis and worth of clinic application extensively.

AIM:To investigate the surgical method and extent of reoperation in the concomitant strabismus patients with surgical under-correction and over-correction.
METHODS: Ninety - six concomitant strabismus patients with surgical under - correction and over -correction were recruited in this study, which included 41 males and 55 females, aged 21. 90±14. 70. All individuals underwent routine eye examinations for strabismus before the surgery. Among the cases with concomitant esotropia, there were over-correction in 23 cases, under-correction in 15 cases. Among the cases with concomitant exotropia, there were over-correction in 28 cases, under - correction in 30 cases. The method of reoperation were based on angle of deviation, the method of original operation and acute visual acuity of patients.

In under - correction cases with concomitant esotropia, 6 cases were performed resection of lateral rectus muscle, the corrective extent was (4. 03±0. 98) ? /mm; 6 cases were performed resection of lateral rectus muscle and recession of medial rectus muscle, the corrective extent was (6. 86 ± 1. 32) ? / mm; 3 cases were performed recession of medial rectus muscle, the corrective extent was ( 4. 33 ± 0. 29 ) ? / mm. In over -correction cases with concomitant exotropia, 16 cases were performed advance of lateral rectus muscle, the corrective extent was (5. 37 ± 1. 56) ? / mm; 6 cases were performed recession of medial rectus muscle, the corrective extent was (6. 29 ± 3. 68) ? / mm; 5 cases were performed advance of lateral rectus muscle and recession of medial rectus muscle, the corrective extent was (5. 46±1. 78) ? / mm; 1 case were performed resection of lateral rectus muscle, the corrective extent was 5. 00? / mm. In under - correction cases with concomitant exotropia, 12 cases were performed resection of medial rectus muscle, the corrective extent was (4. 47 ± 0. 54) ? / mm; 16 cases were performed recession of lateral rectus muscle and resection of medial rectus muscle, the corrective extent was ( 5. 11 ± 0. 75 ) ? / mm; 2 cases were performed recession of lateral rectus muscle, the corrective extent was (2. 65±0. 42) ? / mm.
CONCLUSION: In reoperation of concomitant strabismus patients with over-correction, weakening or/and strengthening the horizontal muscle which were performed surgery before has a greater and more unstable surgical corrective extent. While In reoperation of concomitant strabismuspatients with under -correction, weakening or/ and strengthening the horizontal muscle which were not performed surgery has a normal corrective extent as usual.
