Objective To observe the microanatomy of the bridging veins emptying into the superior sagittal sinus (SSS) for preservation of the bridging veins in surgeries through the anterior transcallosal approach. Methods Blue latex was injected into the SSS and internal jugular veins in 20 cadaver heads (40 sides), in which the bridging veins of the frontal zone and central zone were dissociated and their positions relative to the body surface were determined. Such indexes of the lateral veins in each zone as the caliber, the number of bridging veins, and convergence angle were determined. The opposite hemisphere was manipulated in an identical manner to measure the indexes of the sagittal sinus. Results in an area posterior to the frontal region of the SSS, a "safe zone" was identified where no bridging veins drained into the SSS, covering the area 32.6 nun anterior and 7.5 mm posterior to the coronal suture. After complete dissociation of the bridging veins near the longitudinal fissure in the "safe zone", the fissure allowed an opening width of 4.48~10.86 mm. Conclusion Thorough knowledge of the venous anatomy can help avoid the bridging veins in the anterior transcallosal approach. Total dissociation of the sticking segment and arachnoid segment of the bridging veins can broaden the opening width of the longitudinal fissure without increasing the tension of the bridging veins to better preserve the bridging veins during surgery.

OBJECTIVETo explore the relationship between abdominal fat volume and obstructive sleep apnea hypopnea syndrome in obesity people.
METHODSFrom July 2009 to July 2010, 50 patients with BMI > 25 were prospectively selected for study from the patients who complained of snoring in the Respiratory department. The patients were divided into OSAHS group and non-OSAHS group according to the result of sleep apnea monitoring. All the patients also received full abdominal CT and the whole abdominal fat volume was measured by 3-D CT reconstruction system. SPSS 13.0 was used for statistical analysis.
RESULTSThe whole abdominal fat volume in the two groups was analyzed by T- test, which was significantly different between the two groups (P < 0.01). It showed that there was a statistical relationship between OSAHS and abdominal fat in obesity people.
CONCLUSIONIn obesity people, OSAHS has a close relationship with abdominal fat volume. The abdominal fat volume is markedly higher in OSAHS patients than that in non-OSAHS people.

Objective To express HPV6bL2△N360E7E6 fusion protein in E.coli and preliminarily evaluate its immune effect.Methods Three HPV6b gene fragments,which were L2(1-360 bp),E7 and E6,were fused by overlapping PCR,then were inserted into a prokaryotic expression vector and expressed in E.coli.C57BL/6 mice were immunized with purified fusion protein plus Al(OH)3 and/or CpG adjuvants through intramuscular route,the cellular and humoral immune responses were detected by IFN-γ ELISPOT and ELISA respectively.Results Protein plus CpG adjuvant could induce the strongest cellular immune response to E7 and E6,high antibody titer against L2 could be detected in all immunized groups but there were no significant difference among these groups.Conclutions HPV6bL2△N360E7E6 gene was successfully cloned into pQE30 vector and expressed in E.coli,the fusion protein was also purified and proved that could induce strong cellular and humoral immune responses with appropriate adjuvant in C57 BL/ 6 mice and could be used for future research.
