Objective To elucidate the clinical features and treatment of hemangiopericytomas (HPCs) in different parts of the body, especially in CNS. Methods Clinical data of 41 cases with HPC which were treated at 301 Hospital from 1993 to 2004 were retrospectively analyzed with a review of relevant literature. Follow-up periods ranged from 4 to 150 months after surgery (mean 34 months). Results Among 41 patients of HPC, 21 tumors (51.2%) were found in CNS, and the rest 20 (48.8%) in other systems. Thirteen tumors were diagnosed as malignant HPC. Surgery for tumor removal was performed in all 41 patients. Among the 62 operations, total removal of tumor was achieved in 49 cases and subtotal removal in 13 cases. Recurrence in original site of the tumor occurred 21 times (33.9%) in 14 patients. Five patients (12.1%) presented one or more distant metastasis, and 5 patients died. HPCs in CNS and in other systems displayed similar clinical characteristics and pathological morphology. Conclusions HPC is a rare angioneoplasm that may arise in any part of the body. It is a great challenge to neurosurgeons as well as other surgeons to surgically manage the tumor. HPC has an unfavorable prognosis because its high rate of recurrence and metastasis. HPC in CNS and in other parts of the body should be recognized as one disease. At the same time, HPC in CNS has its distinct features.

Objective To explore the neuroprotective effects of Buchang Naoxintong Capsule on focal cerebral ischemia/reperfusion in rats.Methods Rat model of ischemic reperfusion of cerebral middle artery was established according to Zea Longa's pattern. Rats were randomly divided into pseudo-operation group, ischemia/reperfusion group and Buchang Naoxintong Capsule treated group. The ischemia/reperfusion group and Buchang Naoxintong Capsule treated group were both divided into five subgroups according to reperfusion time or administration time such as 1 d, 3 d, 7 d, 10 d and 15 d. Using immunohistochemical staining method and color image analysis, we measured the expression of vessel endothelium growth factor (VEGF) and Laminin in the region of ischemia. Pathological changes were observed with HE staining and transmission electron microscope. Besides that, the content of brain water was assayed.Results Compared with ischemia/reperfusion group, less numbers of shrinkage or swelling neurons were found in Buchang Naoxintong Capsule treated group.The content of brain water, the expression of VEGF were obviously different between Buchang Naoxintong Capsule treated group and the other two groups (all P

The data of 30 patients simulated before surgery were analyzed using Dextroscope operation planning system in Department of Neuresurgery,General Hospital of Chinese PLA between August 2004 and September 2005,including 2 patients with basilar artery aneurysm,1 with posterior cerebral artery aneurysm,3 with ophthalmic aneurysm,2 with middle cerebral artery aneurysms,1 with anterior cerebral artery aneurysm,7 atlas-occipital malformation,4 meningioma,5 schwannomas,and 5 deep gliomas. The primary CT and MRI data of 30 patients were input to the workstation of Dextroscope system for 3D reconstruction,reunion,segmentation and simulation the entire process of the operation. The relationship of the cranial nerves,vessels and skull base bone with lesions during operations were similar with that of the preoperative simulation on the workstation. The time of clipping aneurysms was reduced from (37.60±13.43) minutes to (23.51±7.62) minutes following application of Dextroscope system,and time of resections of odontoid processes was shortened from 81 minutes to 50 minutes. The ratios of complications were decreased and the patients' Karnofsky scales were 88.7 scores 3 months after operation. Dextroscope operation planning system can help doctors to analyze the patients' image data on a 3-D view and video outlook. The system can raise a precise and detailed operation plan before operation based on the simulation of the operation process,to well know the difficulty and shorten operation duration.

BACKGROUND: Traditional treatment of intertrochanteric fractures includes dynamic hip screw (DHS), dynamic condylar screw (DCS), proximal femoral nail (PFN) and locking compress plate (LCP), most of them have positive results. However, these techniques are not utility for all patients with intertrochanteric fractures, especially for the senile patients whose ages are over 75 years. The intertrochanteric fractures are usually unstable, and most of them have medical complications, thus all these lead to a high failure rate of internal fixation. OBJECTIVE: To identify the methods and the therapeutic effects of hemiarthroplasty or arthreplasty with bone cement for unstable intertrochanteric fractures in senile patients. METHODS: There were 27 senile patients with unstable intertrochanteric fractures, including 11 males and 16 females, with the mean age of 84.6 years. All patients were adopted improved Gibson approach, and greater trochanter should be reduced anatomically as an important sign for measuring the lengths of the lower extremities and fixing of prostheses. Long-stem cementless calcar-raplacements were used in all patients, 2 arthroplasty owing to preexisting osteoarthritis and 25 hemiarthroplasty. RESULTS AND CONCLUSION: Nobody was dead during perioperative period. Weight bearing was permitted as soon as acute pain subsides (7-16 days after operation); 27 patients were followed up for 6 to 48 months, for 20 months on average. No prosthetic looseness and sinking happened, and the calluses were well mineralized. The Harris score was used to evaluate the therapeutic effect at 6 months after operation, which was 78 to 94, of 85.4 points on average, and the rate of fineness was 78%. One posterior hip dislocation and two deep venous thrombosis (DVT) of lower extremities occurred owing to improper caring. The results showed that the prosthetic replacement with bone cement is a reasonable preference for unstable intertrochanteric fractures in senile patients because of many virtues, such as earlier period weight bearing out of bed, low incidence of complications, and satisfaction of functional recovery of extremities.

ObjectiveTo analyze the effect of Tetrandrine (Tet) on neuronal apoptosis and reletted gene expression after acute spinal cord injury (ASCI) in SD rats so as to provide experimental basis for treatment of ASCI.MethodsA total of 95 adult SD rats were.randomly divided into four groups,ie,control group ( n =5 ),ASCI group ( n =30),Tet treatment group ( Tet group,n =30) and methylprednisolone treatment group ( Mp group,n =30).The ASCI model was established with the aid of modified Allen method.The five rats from each group were sacrificed at postoperative 8 hours and 1,3,7,14,21 days respectively to observe the morphology of the injury spinal cord and expressions of cell apoptosis regulation genes ( Bcl-xl,Bcl-xs).The flow cytometry ( FCM ) was used to semiquantitatively analyze the apoptotic cells. ResultsExcept for the control group,the other three groups had morphological changes.Tissue edema,neuronal degeneration with some necrosis and marked inflammatory cell infiltration were founded in the ASCI group.Tissue injury was alleviated in the Tet group and was relatively much milder in the Mp group,with no obvious necrosis or inflammatory cell infiltration.Except for the control group,the number of Bcl-xs positive cells at the same time point was the most in the ASCI group in comparison with the Tet and Mp groups.Meanwhile,the expression of Bcl-xl in all groups reached the peak at day 7 post-injury.The semiquantitative analysis of the apoptotic cells displayed that,except for the control group,the number of apoptotic neurons in other three groups reached the peak at day 7 postinjury and then declined gradually.At the same time point,the apoptotic neurons in the Tet group were less than that in the ASCI group,but more than that in the Mp group. ConclusionsAfter ASCI,Tet plays an active role in intervening the expression of the apoptosis regulation gene and can evidently decrease neuronal apoptosis.Tet treatment can work within 7 days and should be given for ASCI as early as possible.However,Tet exerts weaker effect on ASCI in comparison with MP.
