Objective To explore therapeutic effects and indications of stereotatic puncture and drainage under multi-parameter orientation in the treatment of hypertensive intracerebral hemorrhage(HICH).Methods A total of 56 patients with HICH underwent stereotatic puncture and drainage from October 2003 to May 2005.The entrance position,the puncture plane,the puncture angle and depth,and the length of side hole of drainage tube were accurately designed before operation,and,if necessary,multiple drainage tubes were introduced via one hole.Results According to the Glasgow Outcome Scale(GOS) scores,12 patients recovered well(21.4%),29 patients were moderate disability(51.8%),and 12 patients were severe disability(21.4%).No longstanding coma was noted.Three patients died(5.4%). Conclusions Stereotatic puncture and drainage under multi-parameter orientation has better therapeutic effects and less damages than open operation.The procedure is suitable for 10~60 ml hematoma,especially in elderly patients and deep-located hematoma.The best operation timing is 3~6 hours after the onset of hemorrhage.

Objective To explore the clinical value of CT-guided selective radiofrequency thermocoagulation of the semilunar ganglion for the treatment of primary trigeminal neuralgia(PTN).Methods A total of 24 patients with PTN were included.Under local anesthesia and CT guidance,the semilunar ganglion was punctured by way of the oval foramen via the anterior approach using the Hartel's technique.Selective radiofrequency thermocoagulation was performed after the targets were confirmed by electrical stimulation. Results The pain was completely relieved in 18 patients,partially relieved in 5 patients,and unchanged in 1 patient,the total effective rate being 95.8%(23/24).Follow-up observations for 3~18 months(mean,12 months) in the 24 patients showed recurrence in 2 patients(8.3%).Conclusions CT-guided selective radiofrequency thermocoagulation is a safe,simple,and effective option for the treatment of PTN,especially suitable for the elderly and high-risk patients.

Objective To analysis the efficacy and safety of endovascular graft exclusion for patients with Stanford type B aortic dissection.Methods The clinical data of 46 patients with Stanford type B aortic dissection who received endovascular graft exclusion were analyzed retrospectively.The stents were inserted from the femoral artery to exclude the tear of dissection,and all operation were peformed under digital subtraction angiography (DSA).The operative technique,outcome and complications were observed.Results The stents were successfully performed in all patients.The length of stay in hospital time after operation was 5-20 (12.9 ± 3.4) d.Endo-leak occurred in 2 patients and relieved after re-expanding.Followed up for 2 d to 5.1 years,average 36 months,1 patient got lacunar infarction and 1 patient died after leaving hospital 2 d.The others were free from the serious complications such as aortic dissection and paraplegia.Conclusion Endovascular graft exclusion is safe and effective for the treatment of Stanford type B aortic dissection in hospital and mid-term,and can significantly improve the survival rate and quality of life.

Background and purpose:Glioblastoma is one of the most common intracranial tumors, the morbidity and mortality are both high, and the molecular biological mechanism of the disease is still unclear. In this study, we detected the gene expression of tyrosine kinase receptor (TKR) pathway in primary glioblastoma(GBM) with low-density array, furthermore we analyzed the significance of the gene expression change. Methods:We detected 26 genes of RTK pathway in 10 primary GBM tissues and 9 normal brain tissues (gained from the decompression operation of brain trauma), and analyzed the different expressions of these two kinds of tissues by statistic method.Results:The Ct values of MAP2K1 and MAP2K4 in normal brain tissues were 1.6?1.7 and 2.2?2.1, the Ct values of MAP2K1 and MAP2K4 in primary GBM tissues were 3.9?1.5 and 5.0?2.0, and the Ct different values between normal brain tissues and primary GBM tissues of both genes were -2.3 and -2.8(P

Objective To analyze the biomechanical changes of lateral atlantoaxial articulation by means of three‐dimensional fnite element models of craniocervical junction malformation(CJVM) .Methods CT scan images of 1 patients with CJVM were ob‐tained .The analytical model was constructed by advanced three‐dimension modeling and finite element softwares .A comparison of range of motion difference between the deformity model and normal model ,referring to the experience of clinical observation ,was used to verify the validity of the model .Applying respectively the same loads and boundary conditions on finite element model .The effectiveness was verified by contrastive analysis of the variation in lateral atlantoaxial joint stresses .Results The finite CJVM ele‐ment model with high geometric accuracyand reliable parameter had built .Compared to the results of cadaver test and finite element model based in normal cranio‐cervical junction ,the segment mobility coincides with the actual clinical performance in patients .The stress distribution the lateral junction between atlas and axis of can be reasonably explained the deformation of lateral atlanto‐axial joint structure and its important role in remaining stable between atlantoaxial vertebraeunder different physiological conditions .Con‐clusion The structure of lateral atlantoaxial joint changes in patients of CJVM ,the biomechanical stability for preoperative diagno‐sis and intraoperative treatment operation has a certain value .

Objective To evaluate the security and effect of combination of adjuvant hormonal thera- py and brachytherapy for localized prostate cancer.Methods 22 patients with T1-T2c prostate cancer were treated with transperineal ultrasound-guide 125I seeds prostate implantation and adjuvant hormonal therapy for 4～7 months.The hormonal therapy include 2-4 months before brachytherapy and 1～4 months after brachytherapy.Results The median operation time was ninety minutes,the median number of ~(125)I seeds used was 56.The follow up time was 12～48 months,the cases of PSA
