Preoperative embolization of meningiomas is performed to decrease blood loss at *** it is also observed to produce necrosis and apoptosis in embolized tumors,very little has been described about the immunohistochemical and ultrastructural study on apoptotic tumor cells after embolization of *** this study we pick out four definite embolized meningiomas *** these four cases embolization materials in tumor-feeding blood vessel are observed in paraffin section of HE *** staining and transmission electron microscope(TEM) were submitted to observe meningiomas cells variations after *** apoptosis is detected in these four cases by electron microscope and transferase -mediated dUTP nick end labeling(TUNEL) *** conclusion is that the apoptotic morphological changes is not clear by HE staining,but immunohistochemical and ultrastructural studies show a definite apoptotic features in the embolized meningiomas.

Objective To evaluate effectiveness and complication in microvascular decompression(MVD) treating idiopathic trigeminal neuralgia(ITN).Methods Data from 78 trigeminal neuralgia cases dealt with microvascular decompression were retrospectively and systematically *** Immediate complete relief were found in 67 cases(85.9%),partial relief in 7 cases(8.9%) and failure in 3(3.8%).After a follow-up for 3-37 months in 71 cases,recurrence were found in 5 cases(7.5%). Non-completed peripheral facial paralysis in 7 cases(8.9%)、prosopo-numbness in 5 cases(6.4%)、acoustic sensibility degression、ambiopia and bourdonnement in each 4 cases(5.1%),coordination dyskinesia in 3 cases(3.8%) and intracranial infeion、epilepsy in each 2 cases(2.6%) were found after operation,but no death was *** Microvascular decompression is a safe and efficient way in treating idiopathic trigeminal neuralgia and pay great attention in the entire decompression procedure is the key point to elevate therapeutic efficacy.

Objective To explore the causes of scalp wound infection,pathogen distribution,characteristics of antimicrobial susceptibility and therapeutic measures following craniocerebral trauma caused by the 2008 Sichuan earthquake disaster. Methods Retrospectively analysed the microbiology records of patients admitted with craniocerebral trauma to the Department of Neurosurgery,West China Hospital affiliated to Sichuan *** scalp wound infections following craniocerebral trauma caused by the Wenchuan earthquake on May 12,2008(5.12 earthquake).Results A total of 82 patients suffered from scalp trauma in this study,including 43 cases(50.4%) with wound infections mostly accompanied by severe foreign body contamination,for which the time of first debridement was significantly *** were 59 bacterial strains of infectious pathogenic bacteria,26(44.06%) strains of Gram-positive Staphylococcus aureus and 12(20.33%) strains of Staphylococcus epidermidis;there were 13(22.06%) strains of Gram-negative Enterobacter cloacae,3(5.08%) strains of Klebsiella pneumoniae and 5(8.47%) strains of Serratia *** The rate of scalp wound infections following earthquake-induced craniocerebral trauma,which was dominated by Gram-positive Staphylococcus aureus infection,has been markedly *** debridement and suturing,nutritional support and application of sensitive antibiotics can ameliorate the therapeutic effect.
