Objective To explore the possibility of hearing protection in acoustic neurinoma (AN) resection and to evaluate the effect of dynamic auditory monitoring and the effect of oto-endoscope for hearing protection. Methods From July 2003 to July 2007, there were a total of 138 cases of AN received surgical treatment. Continuous hearing monitoring was conducted in 18 cases with residual hearing. In these 18 cases, there were 6 males and 12 females, with 12 cases in left side and 6 cases in right. Fifteen cases were solitary AN, 3 cases were diagnosed as neurofibromeatosis Ⅱ. Maximal diameters of the tumor varied between 12 and 33 millimeters with an average of 19. 9 millimeters. All cases were operated on by retrosigmoid approach with routine facial nerve monitoring. Ten cases were assisted by oto- endoscope. Eighteen cases were performed accompanying continuous auditory brainstem response (ABR) and electro-cochleogram (EcochG). The patients were given routine hearing function test 7 to 10 days after operation, and reexamined 6 months to 1 year. The duration of follow-up ranged 6 months to 2. 5 years. Hearing data of the last time was thought as the judging result. Preoperative and postoperative hearing standard refer to (AAO-HNS)classifying. Results In all 18 cases, tumors were rsected completely in 16 cases, but sub-totally removed in 2 cases which were Ⅱ neurofibromeatosis. There was no mortality and no severe complication in this series. All the 18 cases had no facial paralysis before operation, and during operation facial nerves in 18 cases were kept anatomic integrity. According to House-Brackmann grade system, for 18 AN patients 7 days after operation only 50.0% (9/18) were kept at grade Ⅰ to Ⅱ, but 88.9% (16/18) were kept at grade Ⅰ to Ⅱ 6 months after operation. Out of 18 cases, hearing function were preserved in 11 cases (61.1%, 11/18) . After operation, there were 4 cases at hearing grade A, 4 cases at hearing grade B, 2 cases at hearing grade C and 1 cases at heating grade D. In all 18 cases, there were 5 cases with tumor diameter more than 20 millimeters, in which only 2 cases of them preserved hearing function (2/5). However, 9 cases preserved their hearing function in the other 13 cases whose tumors diameter less than 20 millimeters (69. 2% ,9/13). In 10 cases assisted by oto-endoscope, 8 cases obtained hearing protection (80.0% ,8/10)and 2 cases lost hearing. During operative monitoring, when drilling posterior lip of internal auditory canal (IAC), dragging and electric coagulating nearby IAC, especially clamping labyrinthine artery, removing tumor in IAC or electric coagulating arachnoid blood vessel on the top of tumor tissue, the ABR waves were affected greatly. Conclusions For the AN patient with preoperative residual hearing, it was necessary to protect hearing by combining continuous auditory monitoring with oto- endoscope technique. Based on these efforts the patient could preserve applicable hearing after operation. Whether or not arachnoidal on the top of AN remain and the conditions about blood supplying were the main factors that affect postoperative hearing. Moreover trauma of labyrinthine artery was the key to postoperative hearing loss.

A total of 1 100 patients underwent renal transplantation in the Organ Transplantation Center,Second Affiliated Department of General Hospital of Chinese PLA between 1988 and 2008 were collected,and retrospective analysis was performed in five female patients with malignant tumor,which appeared at 68 months (20-132 months) following renal transplantation,including 2 with renipelvic and uretal cancer and 3 with bladder cancer. Two of the 3 patients with bladder cancer presented homolateral renipelvic and uretal metastasis. Three cases and 1 case of upper uretal cacer were observed at the homolateral or heterolateral of kidney grafts respectively. The main characteristic of sign was iterative and painless gross hematuria. The 5 patients underwent renal transplantation with intravesical instillation therapy and nephrectomy. All patients were survived without rejection in the 1-62 months follow-up. The incidence of malignancy in renal allograft recipients is much higher than that in normal ones,which is related to the long term use of immunosuppressants. Urinary epithelial cancer is the main complicating carcinoma and the first choice of treatment is surgical operation. Based on the normal renal grafts function,the dose of immunosuppressants should be as low as possible,Moreover,radiotherapy or chemiotherapy should be adopted according to the types and stages of tumor complicating renal transplantation.

Objective To investigate the therapeutic effects of electroacupuncture (EA) on post stroke depres- sion (PSD) after lacunar infarction (LI).Methods Seventy-five PSD patients with lacular infarction were recruited and randomly divided into a control group and an EA group.All patients were treated with Fluoxetine,in addition to EA treat- ment in the EA group.Then all patients were evaluated using the Hamilton Depression Scale (HAMD),the Chinese stroke scale (CSS) and the Barthel Index (BI).The evaluations were carried out at 0,14 and 28 days.Results Depression symptoms (DSs) in the EA group were improved by day 14 of the treatment,and their HAMD scores had decreased.DSs in both groups had improved significantly by day 28,and the HAMD scores in the EA group were then significantly lower than those in the control group.Improvements in neurological impairment and in the activities of daily living were observed earlier in the EA group.Conclusion The combination of EA and Fluoxetine is helpful for PSD with complex patho- genesis and clinical symptoms.Therapeutic effects are enhanced and side effects are reduced.

Objective To investigate the impact of PET-CT on the target volume delineation and precise radiothera?py planning for patients with advanced non-small cell lung cancer (NSCLC). Methods PET-CT scanning was performed in 30 histologically proved NSCLC patients. The gross tumor volume (GTV) was delineated, and radiotherapy planning was es?tablished with identical parameters based on the CT image and PET-CT fused image, respectively. The differences of doses between GTV, planning target volume (PTV) and organsat rise (OAR) were compared. Results PET-CT image results changed the target volume delineation in 30 patients with 8 increased and 22 decreased. There were no differences in GTV and PTV between the VGTV and VPTV statistically, although PET-CT image changed conventional CT image size sketch of GTV and PTV. The V20 of total lung decreased in the PlanPET-CT compared with that of PlanCT (P<0.05), but no differences were found in the V30 of total lung, mean lung dose (MLD), the data of spinal cord, esophagus and heart. Conclusion PET-CT may reduce the radiation injuries in the lung and improve the target dose.

Objective To investigate the clinical value of VVI assessment normal fetal segmental myocardial performance and to establish a nomogram of normal fetus.Methods Digital dynamic fourchamber imaging of 151 healthy fetus(divided 5 groups according to gestation)were collected,then the longitudinal velocity,strain and strain rate of interventricular septal and left lateral wall were measured in systolic and diastolic period respectively.Results Normal systolic and diastolic values for tissue velocitv.strain,and strain rate were established.Tissue velocity was age dependent,whereas strain and strain rate were stable throughout gestation(P>0.05).Tissue velocity was gradually decreased from the base segment to the apical segment(P<0.01),whereas strain and strain rate were stable among all segments in every group(P>0.05).Conclusions Fetal myocardial velocity,strain,and strain rate measuraments are easy to obtain and reproducible,VVI is a novel noninvasive tool to assess quantitatively and objectivelv regional systolic and diastolic function in fetal heart,it is providing another useful modality for evaluating cardiac function.
