The location of jugular foramen is deep and hidden, and its local anatomical structure is complex, so it can be called "the most complicated foramen of skull base". Most of the tumors in this area are benign or low-grade malignant; currently, radical resection is the main treatment method. However, the surgery in the jugular foramen region is still a ticklish problem in neurosurgery, and there are still many shortcomings in the relevant surgical approaches and methods. This paper reviews the development of anatomical research and surgical approaches in the jugular foramen region, and discusses the advantages and disadvantages of common surgical approaches for tumors in this region, so as to provide references for further clinical anatomical research or improved surgical approaches.

A new biosensor was prepared based on conductive polymer poly ( 3 , 4-ethylenedioxythiophene ) ( PEDOT) and 1-pyrenebutanoic acid ( PBA) through π-π stacking, as well as hematin associated with PBA through coordinate bonds of Zr4+ and carboxyl group. Its stability and sensitivity were examined by cyclic voltammetry ( CV) , electrochemical impedance spectroscopy ( EIS) and current-time ( i-t) method. A pair of well defined and quasi-reversible redox peaks was observed when GCE/PEDOT/PBA/hematin was tested by CV in PBS without oxygen. The electron transfer rate constant was estimated to be 4. 8 s-1 . Results indicated that the PEDOT film enhanced the electron transfer process of hematin. When the i-t method was used to detect the response of biosensor to catechol with different concentrations, it displayed a linear response for the reduction of catechol in the range of 0. 5-200 μmol/L. The linear equation was i=0. 018C+0. 006 ( R=0. 9998), and the detection sensitivity was 0. 258 μA (μmol/L· cm2) with a detection limit of 0. 33 nmol/L (S/N=3). The results illustrate that the GCE/PEDOT/PBA/hematin biosensor is very sensitive and stable.

OBJECTIVETo explore the factors that affect the curative effect and the best method of treatment for the patients with maxillofacial cavernous hemangiomas.
METHODS102 cases of maxillofacial cavernous hemangiomas were performed DSA examination and taken serial photography. According to the diameter, number and draining speed of efferent veins of the tumor, the cavernous hemangiomas were classified into two types-the high efferent speed and low efferent speed type. For all of them, were randomly performed embolization of efferent veins with absolute ethanol plus bleomycin-A5 intratumor injection (group I) and bleomycin-A5 intratumor injection alone (group II).
RESULTSThe cure rate and general effective rate has significant difference (P < 0.01) between two groups in 70 patients with high efferent speed veins, while no significant difference (P > 0.05) in 32 patients with low efferent speed veins.
CONCLUSIONSThis new classification is beneficial for seeking method of treatment. The embolization of efferent veins is an effective method for cavernous hemangioma with high efferent speed veins; but for the type with low efferent speed veins, bleomycin-A5 intratumor injection alone could acquire a good results.

Background and purpose: Malignant tumors often relapsed or metastasized after first-line chemotherapy and needed second-line or above treatment. We conducted this study to deifne the maximum-tolerated dose (MTD) of lobaplatin with ifxed docetaxel for Chinese patients in previously treated solid tumors. Methods:Escalating doses of lobaplatin with fixed docetaxel were administered in a modified Fibonacci sequence. The initial doses were lobapla-tin 30 mg/m2 and docetaxel 60 mg/m2, respectively. Escalating doses was 5 mg/m2. The regimen was repeated every 21 days. If no dose-limiting toxicity (DLT) was observed, the next dose level was applied. The procedures were repeated until DLT appeared. The MTD was declared to be one dose level below the level at which DLT appeared. Results:Seventeen patients received fifty-eight cycles chemotherapy at lobaplatin of levelⅠ(30mg/m2), levelⅡ(35 mg/m2)and levelⅢ(40 mg/m2). Cases of complete response (CR), partial response (PR), stable disease (SD) and progression disease (PD) for the whole group were 0, 1, 10 and 3, respectively. Response rate (RR, CR+PR) and disease control rate (DCR, CR+PR+SD) were 7.1%(1/14) and 78.6%(11/14), respectively. The most common toxicity was leukopenia. Three DLTs occurred in 3 patients in the whole group, including 2 DLTs in dose levelⅢ. We declared thus levelⅡwas MTD. Conclusion:MTD of lobaplatin in our re-search was 35 mg/m2 combined with fixed dose of docetaxel. This combination regimen was well tolerated.

OBJECTIVETo analyze the clinical features and treatment of skull base osteosarcoma.
METHODSThe clinical data of 18 patients with skull base osteosarcoma, who were admitted to the CAMS Cancer Hospital from January 2005 to November 2013, were retrospectively analyzed. The patients were followed up by telephone, outpatient review and other means. Fifteen patients were followed up, 4 cases received surgery only, and 11 cases received surgery with adjuvant chemotherapy and/or radiotherapy. Kaplan-Meier survival curve analysis was used to analyze the clinical data and Log rank method was used for verification.
RESULTSNine patients died among the 15 patients who were followed up for 3-103 months (mean 25.0 months): seven patients died of local recurrence, and two patients died of distant metastasis, and six patients were still alive. Four patients received surgery only, with a median survival time of 25.0 months, and 11 patients received comprehensive treatment, with a median survival time of 47.0 months (P = 0.02). Five patients received sub-total resection, with a mean survival time of 47.0 months, and 10 patients received total resection, with a mean survival time of 45.0 months (P = 0.37). The 1- and 2-year recurrence rates were 46.6% and 68.9%, respectively. The overall 1-, 2-, 3- and 5-year survival rates were 82.4%, 61.8%, 36.0% and 36.0%, respectively, with a median survival time of 30.0 months.
CONCLUSIONSTo compare the long bone and head and neck osteosarcoma with skull base osteosarcoma, the skull base osteosarcoma has a lower total resection rate, a higher recurrence rate, and a poorer prognosis. Radical surgery and comprehensive treatment are appropriate for skull base osteosarcoma.
